A 45-year-old male who presents to the emergency department with sudden onset of lip swelling, which began shortly after awakening this morning. He denies any history of allergies and denies any new medications. His current medications include hydrochlorothiazide (HCTZ), captopril, atenolol, atorvastatin, and fexofenadine. What is the most likely cause of this gentleman's symptoms?
ACE inhibitor angioedema is a potentially life-threatening known side effect of captopril. The patient may need emergency intubation to ensure that his airway remains patent. Patients with a history of ACE inhibitor angioedema should not be placed on any ACE inhibitor or an ARB due to the possibility of similar reaction. HCTZ (a diuretic) and atenolol (a beta blocker) are antihypertensives that are generally unlikely to be associated with angioedema. Atorvastatin (a statin) and Fexofenadine (an antihistamine) are unlikely to present with angioedema.

Sinusitis
80% of cases will improve within 2 weeks without antibiotic therapy. MCC is viral. Results from mucociliary clearance and sinus obstruction due to mucosal edema. Mucus accumulation becomes secondarily infected. Bacterial pathogens are similar to those of Ottis media (S pneumoniae, Other strep, Hflu, S aureus, Moraxella). May present with unilateral facial fullness, pressure, tenderness in cheek area. Pain may refer to upper incision or canines. Prudent yellow-green nasal drainage or expectoration. Fever, malaise halitosis, HA and cough. MC site is MAXILLARY for adults, FRONTAL for peds. Bacterial variant will persist more than 10 days. Viral variant will tend to be improving at 10 days. Tx with NSAIDs, oral or nasal decongestants. If symptoms persist for more than 10 days, ABX are indicated. 1st line = amoxicillin, macrolide, or tetracycline therapy if PCN resistance or allergy. Tx for 10 days.

A 30-year-old male presents to your office complaining of sinus and facial pain, congestion, and purulent nasal discharge for one month. He has been treated with two courses of different antibiotics by another provider, and does not feel any improvement in his symptoms. What diagnostic test is indicated?
A CT scan is the current preferred method for sinus imaging of chronic sinusitis. CT imaging has better visualization of mucosal thickening air-fluid levels and bone structures. Plain radiographs and CT scans are of limited use in acute sinusitis, because viral pathogens that cause sinus abnormalities are indistinguishable from bacterial causes.
is characterized by a pale retina, as well as a cherry red spot on the macula.
A central retinal artery occlusion
A 66-year-old female has a chief complaint of vision loss in her left eye. She denies pain and states that this occurred over the past few hours. Her past medical history includes hypertension, high cholesterol, and peripheral vascular disease. Upon funduscopic exam, you note marked hemorrhages in all quadrants and disc edema. The contralateral eye shows only mild hypertensive vascular changes. What is your diagnosis?
A central retinal vein occlusion is characterized by a "blood and thunder" fundus, with marked hemorrhages, tortuous vessels, and optic disc edema.
A 45-year-old male presents with a non-tender nodule protruding from his lower eyelid. There is some surrounding erythema to the conjunctiva, but no discharge is seen. He states that it has been there for one month. He has no visual problems. What is your diagnosis?
A chalazion is a sterile, chronic, and non-painful granulomatous nodule, caused by a previous acute infection in a meibomian gland. It can develop over a period of a few weeks. Treatment is intralesional steroids or surgical curettage.
Hyphema
A collection of red blood cells in the anterior chamber of the eye. Results from trauma to the ciliary body, iris, or anterior structures causes bleeding. May present after incurring trauma to the eye. Perform CT and US to exclude associated orbital fracture or foreign body. If no increase in IOP, limit activity for 72 hours. If increased IOP, topical oral ocular hypotensives, and cycloplegics (atropine).
A 45-year-old presents with a markedly tender nodule protruding from the edge of his upper eyelid. He states that this has been present for 12 hours. No discharge is seen. He denies visual problems. What is the most likely diagnosis?
A hordeolum (sty) is caused by an acute infection of the Zeis or Moll's glands of the eyelid. Symptoms include pain and tenderness. An "internal hordeolum" points to the inner conjunctiva of the lid and an "external hordeolum" points to the skin surface of the eyelid.
A 12 year old male presents with lesions on the palmar surface. They have been present for less than a week. Prior to the lesion appearing there was a small lesion that was assumed to be a bug bite. The lesion bleeds profusely with minimal provocation. What is the most likely diagnosis?
A pyogenic granuloma (PG) occurs at the site of minor trauma such as a bug bite or scratch. The PG grows rapidly forming a popular lesion with a collarette of scale. It will bleed profusely with minimal provocation. The only effective treatment is shave excision with curetting and ablation of the blood vessels that form the base of the PG.
A 35-year-old homeless male presents with a painful red right eye and decreased visual acuity, which occured over the past 48 hours. He doesn't recall any trauma, and prior to this his vision was good. His past history includes alcoholism and liver disease. On physical exam you notice a white opacity in the center of his right cornea. You are unable to do an ophthalmoscopic exam due to the opacity, and a fluorescein staining is strongly positive. What is the likely etiology of the white opacity?
A rapidly progressing central corneal ulcer must be considered first and treated aggressively. An ulcer will show fluorescein staining, due to a break in the corneal epithelium. Pseudomonas, strep pneumonia, herpes, and fungus must be considered as possible causes. An emergent ophthalmology consult can be sight saving.
Corneal Ulcer
A red eye with circumcorneal injection. Commonly a result of infection (bacterial, viral, fungal, or amoebas). Noninfectious causes inculde neurotrophic keratitis, exposure keratitis, severe dry eyes or allergic eye disease, and various ocular or systemic inflammatory disorder. May present with pain, photophobia, tearing, and reduced vision. PE reveals a red eye with mainly circumcorneal injection and purulent watery discarge.
A 24-year-old intoxicated male presents to the emergency department after being in a fight. He was punched in the nose, and now has mild deformity of the nose and some epistaxis. An x-ray reveals a fractured nasal bone. During his physical exam, what must you look for in order to prevent permanent destruction of his nasal septum?
A septal hematoma can cause ischemic necrosis of the nasal septal cartilage if not identified and drained. A deviated septum can be expected with a nasal bone fracture, and must be addressed by the otolaryngologist. Excessive epistaxis that does not resolve with direct pressure and anterior packing may indicate a posterior bleed.

A 54-year-old male presents to you with a sudden onset of severe left eye pain and blurred vision. He states that he is nauseated and vomited twice. He denies any history of eye problems, other than having to wear glasses for reading. His only recent problem has been a mild upper respiratory infection, for which he is taking an over-the-counter decongestant. On physical exam, the vision in the affected eye is 20/200. His pupil is mid-sized and non-reactive to light, and the conjunctiva is markedly injected. What diagnosis must you consider first?
Acute angle closure is characterized by sudden onset of severe eye pain, blurred vision, nausea, vomiting, visual halos, and headache. Physical exam findings can include conjunctival injection, a rock hard ocular globe on palpation, a cloudy cornea, and a mid-position fixed pupil. Normal intraocular pressure is below 21mm Hg. Acute angle closure glaucoma can develop pressures of 60 to 80mm Hg.

Presents as acute onset of continuous vertigo lasting several days to a week. Hearing loss and tinnitus are present. Vertigo gradually improves, but hearing improvement varies. Tx with ABX for febrile patients with suspected bacterial infection. Vestibular suppressants (diazepam, meclizine) during acute phase.
Demographically speaking, in whom are cataracts *most common*?
Adults > 60 yrs old
You are asked to examine an 88-year-old female resident of a nursing home, who presents with a red eye. Her notes from the nursing home say that the patient has had this problem for six months, but now seems to be getting worse despite using daily artificial tears and occasional topical antibiotic drops. On physical exam you notice markedly injected conjunctiva to the right eye, with no discharge. The lower lid appears to be curled in toward the bulbar conjunctiva, with the eyelashes pointing inward. What is the name of this condition?
Aging causes a relaxation in the lower lid retractors, resulting in an entropion. This causes chronic irritation to the bulbar conjunctiva and corneal abrasions. Treatments include taping the lower lid to the cheek, botulinum toxin injection, or surgery.
A 45-year-old female presents with a sudden onset of vertigo, nausea, and vomiting. Upon physical exam, you note that she is holding on to the rails of the bed, and her pain gets worse when you attempt any movement of her head. Neurologic exam is grossly normal. Which combination of the following medications is indicated to treat the patient's symptoms?
All other combinations include an ototoxic medication: furosemide, gentamycin, aspirin, and cisplatin. Treatment of acute vertigo is more effective using a combination of vestibular suppressants (benzodiazepines), anti-emetics (prochlorperazine), and anticholinergics (diphenhydramine or scopolamine).
Your patient has symptoms consistent with perennial allergic rhinitis, and after performing a history and physical examination, you elect to perform an IgE-specific serum antibody test for both food and respiratory allergens. The results return and the patient does not have an IgE positive response to a single allergen tested, yet the patient's total serum IgE is elevated dramatically. What would be the most appropriate next step in the diagnosis and treatment of this patient?
Allergen-specific serum IgE testing is an easy and accurate method for determining the presence of atopic allergy, and with newer in vitro technology available, in vitro testing is at least equivalent to skin testing in efficacy. In vitro assays are safe, specific, cost-effective, and reproducible, and do not require the patient to be free of antihistamines and other medications that may interfere with skin testing. They are also easy and quick and are therefore preferred, especially in children and in anxious patients.

A pt that complains of sudden loss of vision in one eye is experiencing what (term)?
Amaurosis Fugax
Which of the following diagnostic studies is indicated for a patient with amaurosis fugax?
Amaurosis fugax is a monocular vision loss that appears like a curtain passing over the eye, and comes from carotid artery disease. A CT of the head is indicated for lateralizing stroke symptoms. Intraocular pressure is taken for evaluation of chronic or acute glaucoma. A temporal artery biopsy is taken if giant cell arteritis is suspected. An ocular fluorescein angiogram is done to evaluate retinal disorders.

Amoxicillin-clavulanate 45 to 90 mg/kg, divided into BID dosing and administered for 10 days
An 18-year-old female presents with two weeks of severe sore throat and fatigue. Her exam shows an exudative tonsillitis. A mono-spot test is positive, and a rapid strep test is positive. Which of the following medications should be avoided?
Ampicillin should be avoided, because a high percentage of mononucleosis patients develop a fine, non-allergic maculopapular rash when given ampicillin class drugs. The remaining antibiotics are appropriate for treating group A strep. Prednisone is used to reduce the pain and inflammation associated with severe tonsillitis.

What is the most likely type of vertigo in a patient with vertigo who has a positive Dix Hallpike maneuver?
BPPV (Benign Paroxysmal positional vertigo)
A 48-year-old female complains of ear fullness, episodes of tinnitus, and vertigo. She also complains that her hearing is not as good as it used to be. She states that this has occurred sporadically over the past year. What is the most likely diagnosis?
BPPV is characterized by sudden vertigo, made worse with head position change, and accompanied by nausea and vomiting. Meniere syndrome is characterized by episodic severe vertigo, fluctuating sensorineural hearing loss, tinnitus, and ear "fullness." Pathologically, there is distention of the endolymphatic system throughout the inner ear, presumably due to dysfunction of the endolymphatic sac. Labyrinthitis is characterized by severe vertigo and hearing loss, and is likely a result of a viral inner ear infection. Vestibular neuronitis is also a result of a viral inner ear infection, with symptoms of severe vertigo, nausea, and vomiting, without hearing loss. Both labyrinthitis and vestibular neuronitis resolve in one to two weeks. Presbycusis is age related hearing loss.

Acute ear pain hemotympanum hearing loss after flying?
Barotrauma
You are evaluating a patient who is complaining of facial drooping , and inability to close his eye. During the cranial nerve exam you notice he is unable to wrinkle his forehead. Based on this information what is the most likely diagnosis?
Bell's palsy affects cranial nerve VII, the facial paralysis conforms to the all branches of the peripheral nerve including the side of the face, eyelid and forehead muscles. An acute cerebrovascular accident would present only with a facial droop, the ability to close the eye and wrinkle the forehead would be preserved and there would likely be other focal weakness on physical exam. Horner's syndrome is miosis, ptosis and facial flushing and hyperhydrosis caused by abnormalities of the supercervical ganglion along the internal carotid artery.

Blowout Fx
As a diver descends for a deep water dive, at about 10 feet of depth he begins to feel nausea, severe ear pain, and develops vertigo and vomiting. What is the most likely cause of his symptoms?
Boyle's law states that as a diver descends, the increasing external pressure causes an equal decrease in pressure in the middle ear, which must be equalized during the descent. If the middle ear pressure is not equalized, the tympanic membrane becomes severely retracted, due to the negative middle ear pressure. This can result in hemotympanum, hemorrhage, or tympanic membrane perforation. Ascent causes increased pressure in the middle ear as the external pressure is decreased. Equalization techniques must also be used to prevent a tympanic membrane perforation. Decompression sickness occurs on ascent, when nitrogen gas bubbles are forced into the middle ear, and vascular and lymphatic spaces.

A 22-year old female presents to your office complaining of itchy red welts all over her body now fading. She is vacationing from Florida. She has no past medical history and her only medication is an oral contraceptive, but she did take an over-the-counter dipenhydramine four days ago on the flight from Florida to calm her nerves. The welts began after swimming in the ocean in New England three days ago, lasted a few hours, then disappeared spontaneously. They reoccurred Saturday morning again shortly after swimming, lasted a little longer, and again resolved. She relates that they were intensely itchy, red, and raised. She ate out at a restaurant and had seafood Saturday night, and thought that she might be allergic to the seafood, although she ate nothing new or unusual. From the history, which of the following is the likely cause of her urticaria?
Cold urticaria is a hypersensitivity to cold exposure (ie, wind, freezer compartments, water) resulting in histamine release. The hypersensitivity usually presents as localized redness, burning, pruritus, and urticaria in the exposed areas, or the response may progress to generalized systemic reaction, shock, and death. This condition may be familial or acquired. Familial cold urticaria is an autosomal dominant inflammatory disorder (including the Muckle-Wells syndrome), manifested as a burning sensation of the skin occurring about 30 minutes after exposure to cold. Acquired cold urticaria may be associated with medication (ie, griseofulvin) or with infection. Cold urticaria may occur secondarily to cryoglobulinemia or as a complication of syphilis. Most cases of acquired cold urticaria are idiopathic. For diagnosis, an ice cube is usually applied to the skin of the forearm for 4 to 5 minutes, then removed, and the area is observed for 10 minutes. As the skin rewarms, an urticarial wheal appears at the site that may be accompanied by itching. Second-generation antihistamines have been used as first-line treatment. Ebastine is also reported to safely and effectively prevent symptoms from acquired cold urticaria. Use of antileukotrienes in cold urticaria is anecdotal.
An 18-year-old female presents with a history of large open comedones and painful abscesses in both axillae. She has been treated by her primary care provider with oral antibiotics. A thorough physical exam may show which other affected sites?
Common areas of involvement in hydradenitis suppurtiva include the axillae, breasts, anogenital region, perineum, and scalp.
Barotrauma
Common risk factors include air travel, rapid altitude changes, and deep diving. Poor eustachian tube function decreases ability to equalize pressure. Most acute during airplane descent. Swallowing, yawning, or autoinflating ears during airplane descent helps. Slow descent while diving. Myringotomy for severe otalgia and hearing loss. Ventilating tubes for frequent episodes Avoid diving during episodes of URI, allergies, or TM perforation.
vincent's angina
Common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of inter-dental papillae (the sections of gum between adjacent teeth). TRENCH MOUTH, Acute Necrotizing Ulcerative Gingivitis. Presents with severe gingival pain, Profuse gingival bleeding that requires little or no provocation, and Interdental papillae are ulcerated with necrotic slough. All three must be present to Dx. Tx with irrigation and debridement of infected areas. Oral ABX (metronidazole) for systemic involvement.
Gingival Hyperplasia
Commonly caused as a result of drug side effects of CCBs, Phenytoin (and many other anticonvulsants), and Cyclosporine.
Allergic Rhinitis
Condition is associated with pale or violaceous nasal turbinates. Exposure to airborne allergens activates humoral (B-cell) and cytotoxic (T-cell) responses. IgE causes release of inflammatory mediators (histamine, prostaglandins, kinins). Seasonal variant is associated with pollens and spores. Perennial variant is associated with dust, mites, pollution, and pet dander. May present with clear rhinorrhea, sneezing, tearing, conjunctival erythema, eye irritation, and pruritus. Accompanying symptoms may include cough, bronchospasm, and eczematous dermatitis. Yellow boggy masses of nasal polyps seen with chronic cases. Strong family history of atopy or allergies. Allergic Salute Dx with RAST - Radio allergosorbent test. Tx by reducing exposure referral to allergist for immunotherapy for resistant cases. Use of antihistamines, intranasal corticosteroids and saline, antileukotriene and anticholinergic agents.
What type of hearing loss will the Weber and Rinne tests assist in diagnosing?
Conductive
What type of hearing loss is experienced with cerumen impaction?
Conductive hearing loss
What type of hearing loss occurs with tympanic membrane rupture?
Conductive hearing loss
Which of the following will cause conductive hearing loss? A. Mumps B. Syphilis C. Multiple sclerosis D. Otitis media E. Medications
Conductive hearing loss is the result of blockage of sound waves from the external canal to the inner ear. Causes include cerumen, middle ear effusion, otitis media, and occiscle disruption. Multiple sclerosis causes VIIIth cranial nerve disruption and neural hearing loss. Mumps and syphilis can cause sensoryneural hearing loss.
Branchial Cleft Cyst
Congenital epithelial cysts, which arise on the lateral part of the neck from a failure of obliteration of the second branchial cleft in embryonic development, related to gill apparatus of fish. Commonly presents as a solitary, painless mass in the neck of a child or a young adult. A history of intermittent swelling and tenderness of the lesion during upper respiratory tract infection may exist. Discharge may be reported if the lesion is associated with a sinus tract. Tx with ABX if abscess if suspected. Definitive treatment is surgical excision.
A 35-year-old homeless male presents with a painful red right eye and decreased visual acuity, which occured over the past 48 hours. He doesn't recall any trauma, and prior to this his vision was good. His past history includes alcoholism and liver disease.

A 28-year-old male presents with a rashon his hands that is unresponsive to topical steroids. On physicalexam you notice periocular violaceous erythema and edema. He also exhibitssignificant proximal muscle weakness. What is the most likely diagnosis?
Dermatomyositis is an autoimmune disease that targets the skinand skeletal muscle. Skin lesions usually consist of a periorbitalheliotrope rash, which can have associated edema. There can alsobe flat topped violaceous papules (Gottron papules) located on theneck, shoulders, and knuckles. Periungual erythema with telangiectasiasmay also occur. Possible muscular symptoms include muscle tenderness,muscle atrophy, and progressive proximal muscle weakness.
A 16-year-old male was hit on the left side of his face by a line drive baseball. Marked swelling is noted externally to the left eye. There was no loss of consciousness. Upon physical exam, he complains of diplopia during extraocular motion testing. Enophthalmos is noted, as well as decreased sensation of the left cheek. Plain x-rays of the face demonstrate an air-fluid level in the left maxillary sinus, and a fracture of the orbit. Based on this information, what is the most likely diagnosis?
Diplopia is common in an orbital blow out fracture, due to entrapment of the inferior rectus and inferior oblique muscles. Loss of infraorbital sensation occurs from disruption or swelling of the infraorbital nerve. A Le Fort I fracture describes a transverse fracture separating the body of the maxilla from the pterygoid plate and nasal septum. A Le Fort II fracture describes a pyramidal through the central maxilla and hard palate. Movement of the hard palate and nose occurs, but not the eyes. A Le Fort III fracture describes a craniofacial disjunction, wherein the entire face is separated from the skull due to fractures of the frontozygomatic suture line, across the orbit and through the base of the nose, and ethmoids. The entire face shifts, with the globes held in place only by the optic nerve.

A 12-year-old male begins to sneeze, and develops itchy, watery eyes about 15 minutes after being exposed to a cat. There is no respiratory difficulty. What phase of allergic response is he in?
EXPLANATION: The humeral or early phase occurs in the first 15 minutes of being exposed to an allergen. The symptoms are caused by release of histamine. The cellular phase is the late phase, and occurs after four to six hours of allergen exposure. Seasonal allergic rhinitis occurs in a regular pattern each year, corresponding to pollen exposure. Perennial rhinitis occurs year round, and may be more linked with indoor allergen exposures.

Ectropion
A 65-year-old female presents with a red irritation in her right eye. She states that this has been occurring intermittently for about two years. She also states that her eyelids are "droopy," and that she needs plastic surgery. On physical exam you notice a diffusely injected conjunctiva and an outwardly tilted lower eyelid. What is the most likely diagnosis for the abnormal physical finding?
Ectropion Ageing causes a relaxation of the obicularis oris muscle, and will cause the lower eyelid to sag outwardly. This prevents the lower lid from protecting the eye, and frequently results in exposure conjunctivitis and keratitis. Treatment is surgical.

Diagnosis/ENT/Ophthalmology A 56 year-old female presents complaining of intense left eye pain associated with unilateral headache, nausea, and colored rings around lights. On examination you note decreased visual acuity, a pupil that is fixed and mid-dilated, and ciliary flushing. Which of the following is the most likely diagnosis? A. Acute glaucoma B. Migraine C. Episcleritis D. Acute uveitis
Explanations (c) A. Acute glaucoma is an ocular emergency that presents as an acutely painful eye and elevated intraocular pressure. Patients typically complain of acute eye pain associated with unilateral headache, nausea/vomiting, cloudy vision, and colored rings around lights. On exam the pupil is fixed and mid dilated with prominent ciliary flush. (u) B. Migraine headaches have associated unilateral headache and nausea however there would be no pupillary changes. (u) C. Episcleritis is an inflammation of the thin layer of connective tissue between the conjunctiva and sclera. Episcleritis resembles conjunctivitis but is a more localized process and discharge is absent. (u) D. Acute uveitis is frequently due to systemic disorders associated HLA-B27-related conditions ankylosing spondylitis, reactive arthritis, psoriasis, ulcerative colitis, and Crohn's disease. The pupil is usually small, inflammatory cells and flare within the aqueous are present.
Diagnosis/ENT/Ophthalmology A patient presents with a nontender, painless, nodule involving a meibomian gland. Which of the following is the most likely diagnosis? A. Chalazion B. Dacryocystitis C. Entropion D. Hordeolum
Explanations (c) A. Chalazion is characterized by a hard, nontender swelling on the upper or lower lid with redness and swelling of the adjacent conjunctiva and is due to granulomatous inflammation of a meibomian gland. (u) B. Dacryocystitis is an infection of the lacrimal sac due to obstruction of the nasolacrimal system. (u) C. Entropion is an outward turning of the lower lid. (u) D.

Pinguecula
Eye condition caused by chronic actinic exposure, repeated trauma, and dry and windy conditions. May present with elevated, yellowish, fleshy, conjunctiva mass found on the sclera adjacent to the cornea. Painless inflammation may occur. Tx - none necessary, may be respected if cosmetically undesirable or chronically inflamed.
Bacterial Conjunctivitis
Eye condition characterized by acute onset of copious, prudent discharge from BOTH eyes. May present with mild decrease in visual acuity and mild discomfort. Eyes may be "glued" shut upon waking. Common pathogens are strep pneumo, Staph aureus, Haemophilus aegyptius, and Mirabella. Transmitted via direct contact or famines, autoinoculation from one eye to other is typical. Infection is usually self limited. Rare pathogens via sexual contact or vaginal delivery and may result in permanent visual impairment if not treated. Tx is ABX for specific pathogen topically, for rare pathogens TX topical plus systemic ABX.
Blowout Fracture
Eye condition commonly caused by trauma from fist or ball, effecting the floor of the orbit, trapping orbital structures. May present with swelling and misalignment of the eyes, movement restriction, specifically the inability to look up due to entrapment of the infraorbital nerve and musculature. Double vision is common and subcutaneous emphysema and exophthalmos are present. Prompt referral to ophthalmologist, keep pt from sneezing or coughing, use of nasal decongestants, ice packs and cold compresses as well as ABX during transport to ophthalmology.
Amblyopia
Eye condition of reduced visual acuity not correctable by refractive means. Most commonly caused by Strabismus, but may caused by Uremia, or toxins such as alcohol, tobacco, lead, or other toxic substances.

Associated with childhood neck or head irradiation or exposure to readioactive isotopes or iodine with peak occurence 20-25 years later. 1/3 of medullary type are associated with multiple endocrine neoplasia type 2 (MEN2), 1/3 familial, 1/3 sporadic. May present with a painless neck swelling and have a single, palpable, nontender, firm nodule. May also have hoarseness, neck discomfort, or dysphagia. Nodule may enlarge, gland may be stony and hard. Medullary causes flushing, diarrhea, fatigue, cushings syndrome; anaplastic has signs of pressure or invasion (recurrent laryngeal nerve plasy) Dx with TSH, serum thyroglobulin is often elevated, Bx, US, MRI, PET, CT, CXR Tx with surgical resection an near total thyroidectomy are indicated, followed by radiation for anaplastic disease. Monitor for postoperative hypocalcemia. T4 HRT, Radioactive iodine ablation for residual disease.
Oral Candidiasis
Most common in individuals with local or systemic immunosuppression (corticosteroids, chemotherapy, antibiotics). May present with fluctuating throat or mouth discomfort. Erythema of the oral cavity or oropharynx with fluffy, whiter, CURD-LIKE patches overlying erythematous mucosa. White areas are EASILY SCRAPED OFF and bleed. Dx clinically, may use wet prep KOH.

Predisposing factors include trauma, rhinitis, supplemental O2 use, septum deviation, HTN, hereditary telangiectasia (Oiler-Weber-Rend), nasal cocaine, anticoagulants, or coagulopathies. Bleeding is most common in the anterior septum where a confluence of veins forms a superficial venous plexus. Posterior bleeds are associated with atherosclerotic disease and HTN. Most cases respond to direct pressure within 15 minutes. Pt should sit, leaning forward. May need nasal tampon, cauterization or surgicel patch. May use topical vasoconstrictors (phenylephrine, 4% cocaine, oxymetazoline).
Mononucleosis
Most commonly caused by Epstein-Barr Virus (HHV4) and transmitted via saliva. KISSING DISEASE, associated with burkitt's lymphoma, nasopharyngeal carcinoma, pediatric leiomyomas, collagen vascular disease, and other disorders. Presents with fever and sore throat, may have exudative pharyngitis, tonsilitis, gingivitis, and soft palate petechiae. Severe infections exhibit malaise, anorexia and myalgias. Typically have painless posterior cervical node lymphadenopathy. May include splenomegaly (50%), a maculopapular or petechial rash (15%). Administration of amoxicillin incrases incidence of rash to 90%. Hemolytic anemia and thrombocytopenia may develop. Dx with heterophile antibody and screen tests. Will show FALSE POSITIVE SYPHILIS TEST (VDRL) or RPR in 10% of patients. Tx is based on symptoms, use nonaspirin NSAIDs and antipyretics. Antivirals will decrease viral shedding but will not affect course of illness.
Jane, a 21-year-old female, was seen in the office 10 days ago and was diagnosed with perennial allergic rhinitis and sent home with instructions for increased fluids, decongestants, and nasal steroids. She returns today with worsened symptoms of malaise, low-grade fever, nasal discharge, cough that is worse at night, mouth breathing, early morning unilateral pain over sinuses, and congestion. Physical examination reveals thick purulent nasal discharge, postnasal discharge visible in the posterior pharynx, periorbital swelling, and tenderness of sinuses upon palpation. She is 36-weeks pregnant and allergic to penicillin. Of the following, what is the most appropriate antibiotic?
Most patients with a diagnosis of acute rhinosinusitis based on clinical grounds improve without antibiotic therapy. The preferred initial approach in patients with mild to moderate symptoms of short duration is therapy aimed at facilitating sinus drainage, such as oral and topical decongestants, nasal saline lavage, and—in patients with a history of chronic sinusitis or allergies—nasal glucocorticoids. Adult patients who do not improve after seven days, children who do not improve after 10 to 14 days, and patients with more severe symptoms (regardless of duration) should be treated with antibiotics. Empirical therapy should consist of the narrowest-spectrum agent active against the most common bacterial pathogens, including S. pneumoniae and H. influenzae—e.g., amoxicillin. But amoxicillin is contraindicated in patients with urticarial reactions to penicillins, and quinolones are similarly contraindicated in pregnancy. trimethoprim-sulfamethoxazole is contraindicated in the third trimester of pregnancy. The best choice is clindamycin.
What is the tx for TM perforation?

Open angle glaucoma
Asymptomatic, potentially blinding Loss of peripheral vision Intraocular pressure elevated
Open-Angle Glaucoma clinical features
A patient presents to your office with a sudden onset of headache, right eye pain, decrease visual acuity, nausea and vomiting. His intraocular pressure is 47. Which of the following classes of medications are indicated for treatment of this condition? A. Alpha agonists and antihistamines B. Alpha agonists and Beta blockers C. Mydriatics D. Cycloplegics E. Angiotensin converting enzyme inhibitors
Ophthalmic alpha-agonists (brimonidine) and beta blockers (timolol) decrease aqueous humor production, and decrease intraocular pressure. They facilitate aqueous flow through outflow tract and the canal of Schlemm. Other acute treatments include prostaglandin analogs(latanoprost) and carbonic anhydrase inhibitors(acetazolamide). Mydriatics, cycloplegics(tropicamide) and antihistamines( diphenhydramine) can precipitate angle closure glaucoma in patients at risk. Angiotensin converting enzyme inhibitors are used for treating systemic hypertension.

On examination and with staining, you notice a dendritic lesion to the cornea, and an otherwise normal examination. Which of the following medications would be contraindicated in this patient?
Ophthalmic corticosteroids in cases of suspected herpes simplex keratitis are contraindicated.
Papilledema
Optic disc swelling due to raised IOP. Usually bilateral, causing enlargement of the blind spot without visual acuity loss. Acute cases will result in profound loss of visual acuity. Tx with cerebrospinal fluid shunt or optic nerve sheath fenestration for those with progressive visual loss not controlled by medical therapy. Recommend weight loss when appropriate and acetazolamide.

A 60-year-old male presents with complaints of irritation and a white plaque on his tongue. He denies pain. During physical exam you are unable to remove the white plaque from the mucosa with a tongue depressor. What is the most likely diagnosis, represented as follows?
Oral leukoplakia cannot be removed from the mucosa using a tongue depressor like oral thrush can. Lichen planus can mimic candidiasis, squamous cell carcinoma, or hyperkeratosis, and requires a biopsy to diagnose. Glossitis is a generalized inflammation, and loss of papillae of the tongue is caused by vitamin deficiencies, medication reactions, auto immune reactions, or psoriasis. Geographic tongue is an asymptomatic serpiginous area of atrophy and erythema of the anterior tongue. The condition is self-limiting.
Hospitalization Broad spectrum antibiotics Nafcillin, metronidazole

Oropharyngeal melanoma is characterized by varying pigment occurringin an irregularly shaped lesion. Although this is a rarely occurringmelanoma, a biopsy should be done and any pigmented oral lesionshould be excised. Areas which are raised within the lesion usuallyindicate sites of invasion.
Acute Otitis Media
Otalgia in the setting of an upper respiratory tract infection. Bacterial infection of mucosa-lined air spaces of the temporal bone. Often results from eustachian tube obstruction caused by viral URI. Fluid accumulation becomes infected by bacteria (strep pneumo, Hflu, Strep pyogenes). May present with otalgia, aural pressure, decreased hearing, mastoid tenderness, fever, erythema and decreased TM mobility with occasional bullae. Rupture more likely with outward bulging of TM due to severe empyema. Decrease in pain after rupture and onset of otorrhea. Swelling over mastoid or associated cranial neuropathy requires urgent care. Tx with tympanocentesis for recurrent cases after multiple courses of ABX. Myringotomy for severe otalgia or complicated cases. Insertion of tubes if prophylaxis fails. Amoxicillin is 1st line. Erythromycin plus sulfonamide may be used. Augmentin for resistant cases. Prophylaxis for recurrent cases is sulfa or amoxicillin daily for 1-3 months.

Patients who suffer with acne rosacea can relate a history of which outcome?
Patients who suffer with acne rosacea can relate a history of their condition worsening with exposure to hot temperatures, spicy foods, or alcoholic beverages. This is in response to increased reactivity of capillaries. Acne that worsens with the onset of menses is characteristic of acne vulgaris, not acne rosacea. Acne rosacea may resolve spontaneously; however, it is usually present in some form for a lifetime. Exposure to high temperatures, such as those in a steam room, can worsen acne rosacea.
A 54-year-old male patient presents to your office complaining of pain to the left eye with nausea, vomiting, and a headache after being brushed in the eye with his grandchild's stuffed animal.

A 1-day-old infant being examined in the newborn nursery is noted to have a central, 4 mm cataract affecting his right eye. Which of the following is the most appropriate management for this patient? A. Cataract surgery within the next 6 weeks B. Cataract surgery within the next year C. Observation every 3 months D. Observation every 6 months
The answer is A. EXPLANATION: Congenital cataracts that are large and affect visual acuity (e.g., central) must be surgically corrected within the first two months of life (A) to avoid the development of deprivation amblyopia. Observation (C, D, and E) or delayed surgery (B) may result in permanent deprivation amblyopia.

Phenylephrine spray and anterior packing B. Triamcinolone spray and anterior packing C. Azelastine spray and anterior packing D. Momentasone spray and anterior packing
The answer is A. EXPLANATION: Phenylephrine is a topical decongestant, and acts as a vasoconstrictor to aid in stopping minor anterior septal epistaxis. Triamcinolone and momentasone are nasal steroids used for allergic rhinitis. Cromolyn sodium is a mast cell stabilizer, and azelastine is a topical H1 selective antihistamine, used for allergic rhinitis.
A 23-year-old male presents to the clinic complaining of left anterior neck pain that developed over the past week following recovery from an acute upper respiratory infection. On physical exam a tender mass is felt anterior to the left sternocleidomastoid muscle from the mandible inferiorly to the level of the cricoid cartilage. Which of the following is the most likely diagnosis? A. Branchial cleft cyst B. Dermoid cyst C. Peritonsillar abcess D. Salivary gland tumor
The answer is A. EXPLANATION: The development of a neck mass in a young adult following URI is consistent with branchial cleft cyst (A) and thyroglossal duct cyst (E). The location of this mass away from the midline and anterior to the SCM is most consistent with branchial cleft cyst (A). The location of the mass and history are inconsistent with dermoid cysts (B), which are typically midline, peritonsillar abcesses (C), which would be located in the retropharyngeal space, and salivary gland tumors (D), which would be located in the parotid, submandibular, or submental salivary regions.
A 43-year-old female presents to the outpatient clinic complaining of itching and irritation of her right eye. She denies decreased vision or photophobia. On physical exam the patient's eye has the following appearance: Which of the following is the most appropriate management for this patient's condition? A. Daily lid cleansing and application of bacitracin ophthalmic ointment 500 units/g B. Doxycycline 100 mg by mouth once daily C. Incision and drainage D. Referral to an ophthalmologist
The answer is A. EXPLANATION: The patient's symptoms of itching and irritation of the lid margin with an inflamed eyelid and eyelash scaling is consistent with mild anterior blepharitis, which is initially treated with cleansing and the potential addition of a topical antistaphlococcal antibiotic (A). Answers (C) and (E) are appropriate treatments for a hordeolum. Doxycycline once daily (B) can be used as a long-term treatment for posterior blepharitis. The condition doesn't warrant referral (D).
As a diver descends for a deep water dive, at about 10 feet of depth he begins to feel nausea, severe ear pain, and develops vertigo and vomiting. What is the most likely cause of his symptoms? A. Decompression sickness B. Decreasing pressure in the middle ear C. Benign paroxysmal positional vertigo D. Increasing pressure in the middle ear E. Equalization of pressure between the middle ear and eustachian tube
The answer is B. EXPLANATION: Boyle's law states that as a diver descends, the increasing external pressure causes an equal decrease in pressure in the middle ear, which must be equalized during the descent. If the middle ear pressure is not equalized, the tympanic membrane becomes severely retracted, due to the negative middle ear pressure. This can result in hemotympanum, hemorrhage, or tympanic membrane perforation. Ascent causes increased pressure in the middle ear as the external pressure is decreased. Equalization techniques must also be used to prevent a tympanic membrane perforation. Decompression sickness occurs on ascent, when nitrogen gas bubbles are forced into the middle ear, and vascular and lymphatic spaces.
A 60-year-old male presents with complaints of irritation and a white plaque on his tongue. He denies pain. During physical exam you are unable to remove the white plaque from the mucosa with a tongue depressor. What is the most likely diagnosis, represented as follows? A. Oral thrush B. Leukoplakia C. Geographic tongue D. Glossitis E. Lichen planus
The answer is B. EXPLANATION: Oral leukoplakia cannot be removed from the mucosa using a tongue depressor like oral thrush can. Lichen planus can mimic candidiasis, squamous cell carcinoma, or hyperkeratosis, and requires a biopsy to diagnose. Glossitis is a generalized inflammation, and loss of papillae of the tongue is caused by vitamin deficiencies, medication reactions, auto immune reactions, or psoriasis. Geographic tongue is an asymptomatic serpiginous area of atrophy and erythema of the anterior tongue. The condition is self-limiting.
A 65-year-old male presents to you with complaints of decreasing hearing, along with difficulty discerning words when in conversations in noisy environments, such as restaurants. His only medication is simvastatin for hyperlipidemia. The following is his audiogram. He has bilateral decreased high frequency hearing loss, and decreased speech recognition. What is the most likely diagnosis? A. Vestibular schwannoma B. Presbycusis C. Presbystasis D. Cerumen impactions E. Vestibulobasilar insufficiency
The answer is B. EXPLANATION: Presbycusis is age related bilateral loss of high frequency hearing, and decreased word recognition. Presbystasis is age related balance disorder. Vestibular schwannoma (acoustic neuroma) causes unilateral hearing loss. Vestibulobasilar insufficiency results from atherosclerosis of the vertebral arteries, and can cause many symptoms including double vision, speech defects, vertigo, ataxia, and drop attacks.
A 45-year-old male presents with purulent discharge from his right ear for three weeks. He states that despite being treated by his family doctor for an ear infection one month ago, the problem continues to get worse. Upon exam, you note purulent discharge in the ear canal, an erythemic tympanic membrane, and a possible perforation. What are the pathogens most likely to culture positive? A. Strep pneumoniae B. Pseudomonas aeroginosa C. Escherichia coli D. Candida albicans E. Mycoplasma pheumoniae
The answer is B. EXPLANATION: The clinical vignette describes a chronic otitis media. Usually, this refers to a complication of acute otits media with perforation. Pathogens that culture from these infections are usually pseudomonas, proteus, or staphylococcus aureus. Strep pneumoniae is often seen in acute otitis media. E.coli is a urinary tract pathogen. Candida albicans is a cause of vaginitis, and mycoplasma is a respiratory pathogen.
A 43-year-old woman presents to the outpatient clinic complaining of right eye redness, photophobia, and pain. She notes some blurred vision and denies the presence of discharge. On physical exam her visual acuity is 20/20 left eye, and 20/60 right eye. Her right eye has circumcorneal injections and the pupil is 3 mm and responds poorly to light. Her left pupil is 5 mm and responds well. Fluorescein staining of the eye is unremarkable and intraocular pressures are normal. Which of the following treatment regimens should be prescribed? A. Homatropine 5% solution four times daily B. Homatropine 5% solution four times daily and prednisolone 1% solution every 1 or 2 hours while awake C. Prednisolone 1% solution every 1 or 2 hours while awake
The answer is B. EXPLANATION: The patient's presentation of acute uveitis is best treated with topical corticosteroids and cycloplegics (B) once infectious causes (e.g., HSV) have been ruled out. The addition of a cycloplegic helps reduce pain. Antibiotic drops (D) aren't indicated for acute uveitis.
You are evaluating a patient who is complaining of facial drooping , and inability to close his eye. During the cranial nerve exam you notice he is unable to wrinkle his forehead. Based on this information what is the most likely diagnosis? A. Cerebrovascular accident B. Transient ischemic attack C. Bell's palsy
The answer is C. EXPLANATION: Bell's palsy affects cranial nerve VII, the facial paralysis conforms to the all branches of the peripheral nerve including the side of the face, eyelid and forehead muscles. An acute cerebrovascular accident would present only with a facial droop, the ability to close the eye and wrinkle the forehead would be preserved and there would likely be other focal weakness on physical exam. Horner's syndrome is miosis, ptosis and facial flushing and anhydrosis caused by abnormalities of the supercervical ganglion along the internal carotid artery.
A 37-year-old male presents to your office with a history of vision loss in his right eye. He denies any pain, and states that the vision loss occurred suddenly. He noted there was a wavy, "curtain-like" visual disturbance preceding the vision loss. Upon physical exam you notice a cherry red spot over the macula and retinal pallor. What is the most likely diagnosis? A. Macular degeneration B. Retinal detachment C. Central retinal artery occlusion D. Cerebrovascular accident
The answer is C. EXPLANATION: Central retinal artery occlusion is characterized by a sudden, painless vision loss. A cherry red spot is characteristic on the macula, along with pallor to the retina.
Jane, a 21-year-old female, was seen in the office 10 days ago and was diagnosed with perennial allergic rhinitis and sent home with instructions for increased fluids, decongestants, and nasal steroids. She returns today with worsened symptoms of malaise, low-grade fever, nasal discharge, cough that is worse at night, mouth breathing, early morning unilateral pain over sinuses, and congestion. Physical examination reveals thick purulent nasal discharge, postnasal discharge visible in the posterior pharynx, periorbital swelling, and tenderness of sinuses upon palpation. She is 36-weeks pregnant and allergic to penicillin. Of the following, what is the most appropriate antibiotic? A. amoxicillin B. trimethoprim-sulfamethoxazole C. clindamycin D. levofloxacin
The answer is C. EXPLANATION: Most patients with a diagnosis of acute rhinosinusitis based on clinical grounds improve without antibiotic therapy. The preferred initial approach in patients with mild to moderate symptoms of short duration is therapy aimed at facilitating sinus drainage, such as oral and topical decongestants, nasal saline lavage, and—in patients with a history of chronic sinusitis or allergies—nasal glucocorticoids. Adult patients who do not improve after seven days, children who do not improve after 10 to 14 days, and patients with more severe symptoms (regardless of duration) should be treated with antibiotics. Empirical therapy should consist of the narrowest-spectrum agent active against the most common bacterial pathogens, including S. pneumoniae and H. influenzae—e.g., amoxicillin. But amoxicillin is contraindicated in patients with urticarial reactions to penicillins, and quinolones are similarly contraindicated in pregnancy. trimethoprim-sulfamethoxazole is contraindicated in the third trimester of pregnancy. The best choice is clindamycin.
A 55-year-old male presents with severe swelling to his left eye. He denies injury or allergies. He states that he has had a severe sinus infection for the past two weeks. What is the most likely diagnosis for the following physical finding? A. Allergic reaction B. Eyelid abcess C. Orbital cellulitis D. Erysipelas
The answer is C. EXPLANATION: The image shows a severe orbital cellulitis. These infections often spread from paranasal sinus infections. Multiple pathogens may be involved, such as s.aureus, s. pheumoniae, and anaerobes. An eyelid abscess would be more localized. Allergic reactions that cause angioedema around the eye are usually bilateral, and also pruritic.
A 68-year-old man presents to the outpatient clinic complaining of decreased hearing in his left ear. The following is seen on otoscopic evaluation. Which of the following is the most likely diagnosis? A. Acute otitis media B. Cerumen impaction C. Cholesteatoma D. Chronic otitis media
The answer is C. EXPLANATION: The photo depicts a classic cholesteatoma (C) effecting the pars flaccida. The localized nature of the findings and lack of inflammation make otitis media (A and D) unlikely. Any perforation in the TM (E) would be secondary to the cholesteatoma and the visible TM is inconsistent with a diagnosis of impacted cerumen (B).
An 18-year-old female presents with two weeks of severe sore throat and fatigue. Her exam shows an exudative tonsillitis. A mono-spot test is positive, and a rapid strep test is positive. Which of the following medications should be avoided? A. Erythromycin B. Clindamycin C. Cephalexin D. Ampicillin E. Prednisone
The answer is D. EXPLANATION: Ampicillin should be avoided, because a high percentage of mononucleosis patients develop a fine, non-allergic maculopapular rash when given ampicillin class drugs. The remaining antibiotics are appropriate for treating group A strep. Prednisone is used to reduce the pain and inflammation associated with severe tonsillitis.
A 20-year-old male presents with cough, nasal congestion, and a low grade fever for one week. His cough seems to be getting worse, which is the reason for his visit. His past medical history includes asthma and nasal polyps. On physical exam, his temperature is 101°F, his pharynx is erythemic, and there is grey nasal discharge with a few nasal polyps seen using a nasal speculum. His lungs have a few expiratory wheezes bilaterally. What medication is to be avoided in this patient? A. Penicillin B. Acetaminophen C. Erythomycin D. Aspirin E. Ciprofloxacin
The answer is D. EXPLANATION: Aspirin should be avoided in patients with asthma and nasal polyps. Aspirin can precipitate bronchospasm in these patients, due to immunologic salicylate sensitivity.
A 5-year-old boy presents to urgent care complaining of painful lesions in his mouth that have made eating difficult the past 2 days. The mother confirms he has been unable to eat for 48 hours, but has been able to sip water. On physical exam he has a temperature of 102.6 F; numerous small vesicles and ulcers on the buccal mucosa and tongue, inflamed gingiva; and tender anterior cervical adenopathy. Which of the following is the most likely diagnosis? A. Aphthous ulcers B. Hand, foot, and mouth disease C. Herpangina D. Herpes simplex gingivostomatitis
The answer is D. EXPLANATION: The classic presentation of initial herpes simplex infection (D) includes multiple small, painful vesicles or ulcers on the mucousa with gingival involvement, fever, and adenopathy. (A), (B), and (C) all present with ulcers, but typically involve an isolated area (A), or the tonsils and posterior pharynx (B and C). Reference:
A 63-year-old female complains of a 5-day history of a persistent left-sided headache, which she has not experienced before. She also notes a tender swollen area around her left temple, which appeared around the same time. On examination you note tenderness and prominence of the left temporal artery. You order an ESR, which is 75 mm/h. What is your best course of action at this time? A. Repeat the ESR in 72 hours. B. Begin prednisone 20 mg/d and increase if symptoms persist. C. Refer to a rheumatologist for appointment next month, with a trial of nonsteroidal anti-inflammatory drugs (NSAIDs). D. Begin prednisone 60 mg/d immediately. E. Refer for a temporal artery biopsy next week, with a trial of hydrocodone for analgesia.
The answer is D. EXPLANATION: The correct answer is (D). The patient's history and physical examination findings point to giant cell arteritis (temporal arteritis) as the most likely cause, prompting immediate treatment with high-dose prednisone to prevent visual loss. The patient meets the criteria for clinical diagnosis of giant cell arteritis without a temporal artery biopsy, but it is recommended for definitive diagnosis due to the complications associated with long-term corticosteroid treatment. Treatment with prednisone should not be withheld while waiting for a temporal artery biopsy. NSAIDs and hydrocodone do not prevent the complications of temporal arteritis.
A 23-year-old man presents to the outpatient clinic for follow-up from a recent urgent care visit. He complains of sore throat, fever, fatigue, myalgias, and a rash that started 5 days ago, and have worsened since he was seen in the urgent care 3 days ago. The patient appears non-toxic with a temperature of 39.4 degrees Celsius. Physical exam reveals pharyngeal and tonsillar erythema without exudates, generalized lymphadenopathy, a morbilliform rash on his trunk, and no hepatosplenomegaly. A rapid strep screen and Monospot performed at the local urgent care were reportedly negative. Which of the following laboratory tests is most likely to confirm the expected diagnosis? A. Complete blood count B. Cytomegalovirus titer C. Group A beta-hemolytic strep culture D. HIV viral load
The answer is D. EXPLANATION: The patient presentation is consistent with acute retroviral syndrome, which is best confirmed during this initial presentation phase through direct testing for the HIV virus, such as an HIV viral load (D). The lack of tonsillar exudates, a negative monospot, and presence of generalized adenopathy make infectious mononucleosis (B and E) less likely. A CBC (A) may show lymphopenia and support the diagnosis, but it doesn't confirm the diagnosis.
A 3-year-old girl presents to the otolaryngologist for evaluation of a persistent left ear infection and drainage that have failed to respond to multiple antibiotic regimens. Which of the following is the most likely causative organism for this patient's condition? A. Aspergillus B. Chlamydia pneumoniae C. E. coli D. Streptococcus pneumoniae E. Staphylococcus aureus
The answer is E. EXPLANATION: Chronic otitis media is typically caused by P. aeruginosa, H. influenzae, S. aureus (D), Proteus species, Klebsiella pneumoniae, or Moraxella catarrhalis. Aspergillus (A) and E. coli (C) are associated with otitis externa and streptococcus pneumoniae (D) is the most common bacterial cause of otitis media. Reference:
Chronic Otitis Media
The clinical Hallmark of this disease is purulent aural discharge. Results from recurrent acute variant, certain diseases, and trauma. Pathogens include P aeruginosa, Proteus species, S aureus, and mixed anaerobic infections. May present with TM perforation, mucosal changes, osseous changes, purulent aural discharge with or without otalgia, and conductive hearing loss. Tx with regular removal of infected debris, protection against water exposure. Definitive management is TM reconstruction. Topic ABX drops, oral Cipro.
A 50 year old female presents multiple episodes of sudden onset of vertigo over the past few months. She states this began after turning her head suddenly. The events last for about 30 seconds. She complained of nausea during the spells. She denies headaches, hearing problems, focal weakness or recent illnesses. What is the most appropriate clinical intervention.
The clinical history suggests benign paroxysmal positional vertigo (BPPV). The Dix-Halpike test and Nylen Barany test are physical exam techniques to diagnose positional vertigo. The Epley maneuver is a therapeutic canalith repositioning maneuver for debris in the posterior semicircular canal, which is the cause of BPPV. The maneuver works in 80% of the patients with BPPV. A head CT would be indicated for any patient with neurologic symptoms or a new onset of headache.
A 60-year-old male presents with scaling feet for several months. The nails are spared. The patient has tried over-the-counter hydrocortisone cream with no help. KOH shows branching hyphae and spores. Which of the following should be part of an appropriate treatment regimen?
The clinical presentation and KOH results are consistent with tinea pedis or athlete's foot. Since the nails are unaffected, topical treatment with clotrimazole is appropriate. Lotrisone contains an antifungal and a steroid; this combination medication is not appropriate for this patient. Fluticasone is a class 3 topical steroid that would worsen this patient's condition. Mupirocin is a topical antibiotic and will not help resolve a fungal infection.
An 18 month old female is brought to the pediatricians office with a history of cough, fever of 102, and decreased fluid intake. Her immunizations are not up to date as the family just moved to the United States from out of the country. On physical exam she is drooling and sitting up in a "tripod position" with mild stridor. What is the most appropriate treatment indicated for this condition?
The clinical presentation suggests epiglotitis. This is an emergent airway condition. The anesthesiologist , or the pediatric otolaryngologist must be called to stand by to intubate or insert a tracheostomy if the patients airway closes. Racemic epinephrine via nebulizer relieves much of the edema to the upper airway in a patient with epiglotitis. It is a stabilizing measure until definitive care can be arranged. Oxygen and antibiotics should administered emergently also. No x-rays are indicated when the presentation is classic. Albuterol is a beta-agonist used for treatment of asthma. Budesonide,a steroid and ipratropium, an anticholinergic agent are most often used in combination with albuterol for treatment emphysema and asthma.
An 18 month old female is brought to the pediatricians office with a history of cough, fever of 102, and decreased fluid intake. Her immunizations are not up to date as the family just moved to the United States from out of the country. On physical exam she is drooling and sitting up in a "tripod position" with mild stridor. What is the most appropriate treatment indicated for this condition? A. Humidified air B. Albuterol nebulizer C. Budesonide nebulizer D. Recemic epinephrine nebulizer E. Ipratropium nebulizer
The clinical presentation suggests epiglotitis. This is an emergent airway condition. The anesthesiologist , or the pediatric otolaryngologist must be called to stand by to intubate or insert a tracheostomy if the patients airway closes. Racemic epinephrine via nebulizer relieves much of the edema to the upper airway in a patient with epiglotitis. It is a stabilizing measure until definitive care can be arranged. Oxygen and antibiotics should administered emergently also. No x-rays are indicated when the presentation is classic. Albuterol is a beta-agonist used for treatment of asthma. Budesonide,a steroid and ipratropium, an anticholinergic agent are most often used in combination with albuterol for treatment emphysema and asthma.
A 71 year old female presents with complaint of a severe headache for 2 days. The patient denies a history of headaches in the past. She complains of a 2 week periods of morning shoulder and pelvic stiffness. There also a history of jaw pain when she chews her food. The past medical history is remarkable for well controlled hypertension, hyperlipidemia. On physical exam there is a markedly tender scalp and left temporal artery. The neurologic exam is normal. Besides a temporal artery biopsy what other diagnostic test is most indicated?
The clinical scenario suggests giant cell arteritis (GCA) or temporal arteritis. An erythrocyte sedimentation rate( ESR) or C-reactive protein( CRP) can aid in the diagnosis of GCA when evaluating an inflammatory vasculitis such as GCA. Treatment is based on history and physical and not the result of the ESR. Temporal artery biopsy is the gold standard for diagnosis.
A 12-month-old female presents with bilateral lichenification, scaling, and excoriations in the antecubital fossae and popliteal fossae. Which of the following should treatment include?
The first line treatment for atopic dermatitis is a topical steroid, such as triamcinolone ointment. Oral hydroxyzine is an antihistamine that is used to control pruritis in atopic dermatitis. Clotrimazole/betamethasone diproprionate cream is a combination antifungal and topical steroid. There are no clinical indications for this medication. An antifungal such as ketoconazole is not indicated. The oral hydroxyzine is an antihistamine that is used to help control pruritis. Petroleum jelly is an excellent emollient; however, augmentin is not indicated unless there is a secondary infection. No infection is present in this patient.
The patient below comes to your office for a routine physical exam. She has no complaints. You note the following physical examination findings. There is an absence of tenderness with palpation. What is the most likely diagnosis?
The following finding represents xanthelasma, which is commonly associated with hyperlipidemia. In some familial hyperlipidemias, skin eruptions or nodules may form (xanthomas). Gout and rheumatoid arthritis are types of inflammatory arthritis and manifestations are more likely to be found around joints. Gouty tophi may also be found around the helix of the ear and are usually whitish in color in contrast to the yellow xanthelasma. There is no evidence of erythema consistent with cellulitis and the patient is asymptomatic. Lacrimal duct obstruction would likely be symptomatic and there would be tender swelling over the lacrimal duct.
You are evaluating an 80-year-old female for the first time. She has a history of mild Alzheimer's disease, for which she takes Aricept. She states that she feels fine but her daughter feels she is depressed and has been complaining of not feeling well. Her daughter admits that the patient has a history of primary hyperparathyroidism. What laboratory results would be most consistent with her diagnosis of hyperparathyroidism?
The hallmark of primary hyperparathyroidism is a high serum calcium and high intact PTH. A low intact PTH is consistent with hypoparathyroidism. The urine serum calcium is usually high in primary hyperparathyroidism. Cortisol is related to endocrine conditions affecting the adrenal cortex.
A 50-year-old male states that his eye is bothering him since yesterday. He complains of pain and redness. He states that he mowed his lawn yesterday and that it was windy outside. He attempted to irrigate the eye but still has significant irritation. He notes that it hurts to blink his eyes. What is the correct sequence of steps to treat this condition?
The history suggests a retained foreign body to the upper eyelid. A fluorescein stain will reveal significant superficial vertical scratches on the cornea. An upper eyelid eversion must be done, to inspect for and remove the foreign body. If the practitioner is successful in removing the foreign body, relief of the irritation will be immediate.
A 54-year-old female presents complaining of decreased visual acuity to her right eye over the past few hours. She denies pain, and describes having wavy vision and seeing flashes of light. Her visual acuity in the affected eye is 20/200. What condition best describes the following physical finding?
The image demonstrates a detached retina. The superior aspect of the retina appears wavy and flowing. A central retinal artery occlusion is characterized by a pale retina, as well as a cherry red spot on the macula. Open angle glaucoma does not cause acute vision loss. Angle closure glaucoma causes painful acute vision loss. Optic neuritis is characterized by painful visual loss and a swollen optic disc.
A 55-year-old male presents with severe swelling to his left eye. He denies injury or allergies. He states that he has had a severe sinus infection for the past two weeks. What is the most likely diagnosis for the following physical finding?
The image shows a severe orbital cellulitis. These infections often spread from paranasal sinus infections. Multiple pathogens may be involved, such as s.aureus, s. pheumoniae, and anaerobes. An eyelid abscess would be more localized. Allergic reactions that cause angioedema around the eye are usually bilateral, and also pruritic.
What is the most appropriate management for the lesion shown, which is noticed on a 50-year-old female?
The lesion is asymmetric with irregular margins. The optimal treatment of this lesion would be excision with 1 cm margins. A punch biopsy would only be performed if excision cannot be performed. Cryotherapy would destroy the lesion and prohibit a diagnosis and staging.
These lesions are visible on a 14-year-old female's forehead. What medication is this disorder best treated with?
The lesions are comedones (open and closed). Optimal treatment should be with topical retinoids such as tretinoin and adapalene, as these are comedolytic. Topical erythromycin is indicated in inflammatory acne, not comedonal acne as pictured. Benzoyl peroxide only has mild comedolytic activity and erythromycin has none. This combination medication would be more appropriate for inflammatory acne. Doxycycline has no comedolytic activity.
A 21-year-old man presents to the emergency department complaining of a swollen left ear (cauliflower) after he experienced blunt trauma in a collegiate wrestling match. Which of the following is the most appropriate management for this condition?
The patient has an auricular hematoma that must be evacuated to prevent cartilage necrosis or infection. answer: *Evacuation, antibiotics, and splinting* -remove the hematoma, minimize the risk of infection, and help prevent the re-accumulation of blood.
A 24-year-old female presents with hyperpigmented macules on her cheeks, nose, and upper lip. They have been present for a couple of months. Her current medications include oral LoEstrin 24 Fe, cetirizine, and a multivitamin daily. What is the most likely diagnosis?
The patient is experiencing melasma secondary to the use of oral contraceptives. This is a frequent cause of melasma. Melasma can also be precipitated by hormonal changes that occur during pregnancy. The condition will resolve upon discontinuation of the oral contraceptive. A congenital nevus is a nevus that presents within the first year of life. It is monitored in the same way as acquired nevi. They can be larger than acquired nevi, with only a slight increase in chance of malignant change over time. Post-inflammatory hyperpigmentation includes darker areas of pigmentation that can result after inflammation on the skin. Common causes include acne and atopic dermatitis. The hyperpigmentation will resolve over time. A Café-au-lait macule is a type of birthmark. It is usually light tan to light brown in appearance, and can vary greatly in size. They are usually benign, but can be associated with neurofibromatosis when more than six, with a diameter greater than 1.5 cm, are present.
A 25-year-old female presents with a complaint of dry, cracking hands for two months. She has never had any rashes or similar problems. She does not work outside the home. She is the mother of a 6-month-old healthy female. Over-the-counter lotions have been tried, but they sting with application. What is the next appropriate step?
The patient most likely has an irritant dermatitis, secondary to increased water exposure, from having an infant. Appropriate treatment includes a topical steroid, like triamcinolone. Ointments are better vehicles than creams, as they penetrate better and moisturize. Using petroleum based moisturizers are more effective than oil based in repairing the epidermis. There is no evidence at this point of an allergen causing the outbreak. If the disorder is resistant to treatment, then patch testing to determine the allergen may be an appropriate step. A punch biopsy is not indicated, unless there is no response to treatment. A KOH test would be indicated if the rash was suspicious for a fungal infection. If the patient does not respond to treatment with a topical steroid, KOH testing may be indicated.
A 45-year-old male presents with a history of thick, adherent yellow scaling in his scalp, and red scaling patches with fissuring in post auricular areas bilaterally. Which of the following are other areas of potential involvement?
The patient presents with seborrheic dermatitis. Other areas of potential involvement include the eyebrows, eyelashes, and beard area. Antecubital and popliteal fossae are common areas of involvement in atopic dermatitis; not seborrheic dermatitis. The palms and soles are not involved in seborrheic dermatitis. The trunk and neck are not usually affected in seborrheic dermatitis.
A 63-year-old female complains of a 5-day history of a persistent left-sided headache, which she has not experienced before. She also notes a tender swollen area around her left temple, which appeared around the same time. On examination you note tenderness and prominence of the left temporal artery. You order an ESR, which is 75 mm/h. What is your best course of action at this time?
The patient's history and physical examination findings point to giant cell arteritis (temporal arteritis) as the most likely cause, prompting immediate treatment with high-dose prednisone to prevent visual loss. The patient meets the criteria for clinical diagnosis of giant cell arteritis without a temporal artery biopsy, but it is recommended for definitive diagnosis due to the complications associated with long-term corticosteroid treatment. Treatment with prednisone should not be withheld while waiting for a temporal artery biopsy. NSAIDs and hydrocodone do not prevent the complications of temporal arteritis.
You are examining n 42-year-old male with the following physical examination findings (see picture below). What symptoms would most likely correspond to his diagnosis?
The patient's physical examination findings suggest acanthosis nigricans, a condition associated with diabetes mellitus. This patient would most likely present with polydipsia and polyuria at diagnosis. He may have weight loss and fatigue. Anxiety and palpitaions are not as likely to present symptoms of diabetes.
A 38-year-old male complains of increasing fatigue, weakness, weight loss, and intermittent nausea, vomiting, and diarrhea over the past few months. He has noted some agitation at times. When this first started he thought that this was related to a virus but the GI symptoms have reoccurred on multiple occasions. Labs show a complete blood count (CBC) within the normal reference range. He is noted to have hyponatremia. On examination you note the multiple areas of hyperpigmentation as seen below. His blood pressure in the office is 100/50, P = 66, T = 97.1˚F. What test would you order to confirm your suspected diagnosis?
The patient's symptoms and examination findings are consistent with a diagnosis of Addison's disease, which is most likely due to an autoimmune process that destroys the adrenal glands resulting in a chronic adrenal insufficiency. The cosyntropin (ACTH) stimulation test should reveal a low am cortisol level and an elevated ACTH level if he has Addison's disease. The dexamethasone suppression test, choice (A), is a laboratory test for Cushing's syndrome. The vasopressin challenge test, choice (B), is a laboratory test for diagnosis of diabetes insipidus. A radioactive iodine uptake scan, choice (C), is used in the diagnosis of thyroid disease (hyperthyroidism and thyroid nodules). A follicular stimulation test, choice (E), is a factitious test.
You are conducting a physical exam on a female, who was referred to you from an optometrist. She sought a visual screening due to progressive loss of visual acuity. She has not been seen by a physician in 10 years due to lack of insurance. She admits to a 15 lb weight gain in the past three years, and also complains of parasthesias in her feet. During an ophthalmoscopic exam you notice deep retinal microvascular hemorrhages, and cotton wool spots. What is the most likely cause of her visual disorder?
The patient's symptoms suggest a likelihood of diabetes. Retinal findings can include microaneurysms, deep hemorrhages, a flame-shaped hemorrhage, exudates, and cotton wool spots.
A 24-year-old female comes into the clinic complaining of a severe sore throat. She was seen three days ago at an urgent care facility, and was given amoxicillin. She states that the pain is worse, she is unable to drink fluids, and is now having difficulty swallowing. She talks with a muffled voice. A physical exam reveals a markedly swollen and erythemic right tonsil and tonsillar pillar, with the uvula deviating to the left. The patient has extreme difficulty opening her mouth. What is the most likely diagnosis?
The physical exam is highly suspicious for peritonsillar abcess, which must be considered first. Tonisllar cellulitis, or phlegmon, is swelling and enlargement of the tonsil and peritonsillar tissue, without the presence of fluctuant abcess. Uvulitis can exist with a peritonsillar abcess or tonsillitis, but isolated uvulitis usually includes symmetric swelling and erythema as a result of irritation (snoring), allergy (angioedema), or infection from upper respiratory pathogens. Diphtheria is a tonsillitis, with a characteristic gray pseudomembrane on the tonsils and upper airway, caused by corneybacterium diphtheriae.
An 8-year-old male with hair loss, pruritus, and posterior cervical lymphadenopathy has a + culture on dermatophyte test medium (DTM). Which of the following is the most appropriate treatment?
The positive DTM confirms the diagnosis of tinea capitis. The only approved treatment for tinea capitis is griseofulvin. In tinea capitis, the dermatophyte invades the hair shaft and topical treatment is not effective. An antifungal shampoo is often used as an adjunct to treatment. Keflex is an oral antibiotic, which will not help treat the fungal infection. Desonide is a topical steroid that will worsen the fungal infection.
What will fundoscopic exam reveal of the pt w/ retinal detachment?
There will be relative afferent pupillary defect. Fundoscopic exam may reveal the ridges (rugae) of the displace retina flapping in the vitreous humor
A 72-year-old farmer presents with multiple rough adherent scaly lesions on his scalp. They are better felt than seen. He reports mild pain when he inadvertently scratches them. What would the most effective management include for this patient?
These lesions are consistent with actinic keratoses. Treatment is indicated, as 10% of these lesions progress to squamous cell carcinoma. First line treatment is 5-Fu cream 5%. Excision is not indicated for actinic keratoses. Doxycycline is an antibiotic used to treat acne and various bacterial infections, and it is not an effective treatment for actinic Keratosis.
A two-year-old male presents with a noduleon the side of his index finger. His mother states that he has hadthis nodule on one prior occurrence during infancy, and it resolved onits own. What is the most likely diagnosis?
This child has a recurrent digital fibroma. It is a smooth, firm,pink nodule that occurs on the fingers and toes up through earlychildhood. Surgical excision is recommended so that the functionof the digit is not impaired.
A 5-year-old boy presents with a tense,fluid filled blister on his fingertip. What organism is most likelyto be found when the lesion is cultured?
This child has blistering distal dactylitis. This is a form ofimpetigo, and is caused by either streptococcuspyogenes or staphylococcus aureus.
A 12-year-old female presents with linearlydistributed light brown papules on her arm. They are asymptomaticand have been present for several years. The mother states that theyappear to grow as the child grows. What treatment is necessary?
This condition is consistent with a linear epidermal nevus. Theycan appear at any age, but are usually present at or shortly afterbirth. The pigmented papules are arranged linearly and can occuron any skin surface. They are not symptomatic and will grow withthe child. There is no treatment necessary.
A six-month-old infant presents to the primary care provider with complaints of a spreading rash. The physical exam shows multiple yellow-brown macules and plaques that urticate when stroked. What would an appropriate treatment regimen include?
This condition is consistent with urticarial pigmentosa, and it will resolve over time. However, certain things such as NSAIDS, codeine, and scopolamine, as well as extreme temperatures, can cause such reactions as anaphylaxis. This condition is frequently mistaken for child abuse, as the lesions can look like small finger sized bruises. It is consistent, however, with urticaria pigmentosa, which is an accumulation of mast cells in the skin, as indicated by urtication of the lesion after gentle stroking. Urticaria pigmentosa will resolve; however, it will take longer than a week to resolve. Ketoconazole cream is an antifungal that is used to treat fungal infections.
Cholesteatoma
This condition presents with granulation debris or keratin over the tympanic membrane. Variety of chronic otitis media, due to prolonged eustachian tube dysfunction. Creation of squamous epitherlium-lined sac filled with keratin, which may become chronically infected. Will usually erode bone (penetration of mastoid). May eventually erode inner ear, facial nerve, and spread intracranially (rare). Presents with epitympanic retraction pocket or marginal TM perforation that exudes keratin or granulation debris. Tx with surgical marsupialization or removal of sac.
How will papilledema look on fundoscopic exam?
This disc appears swollen and the margins are blurred with an obliteration of the vessels. The patient may be asymptomatic or may cmplain of transient visual alterations that last for seconds.
A two-month-old bottle fed infant female presents with a sharply demarcated scaling red rash on the face and in the diaper area. The mother reports that her child has been irritable and has had diarrhea. The primary care provider has treated with hydrocortisone 2.5% ointment bid for two weeks with no improvement. What should be the next step in confirming the diagnosis?
This infant is displaying classic signs of zinc deficiency. This disorder can occur in infants who are bottle fed. Treatment with topical steroids will not improve the condition until the zinc level is corrected. A punch biopsy would not help in diagnosing the zinc deficiency that this patient is exhibiting. Bacterial and viral cultures will not be helpful in establishing the diagnosis. A KOH is used to diagnose fungal infections. The KOH and bacterial culture will not be helpful in establishing the diagnosis of zinc deficiency.
A 26-year-old female presents with a history of a rash around her neck, off and on for several years. It has been treated with mid potency prescription topical steroids, only to recur again. She reports that during treatment she will discontinue wearing jewelry until the rash resolves. The patient complains of pruritis but no other symptoms. What is the most likely diagnosis?
This is a classic contact dermatitis, secondary to nickel allergy. Nickel is a very common metal that is contained in metals, clothing, and jewelry. It is a delayed, cell mediated hypersensitivity reaction, so it takes multiple exposures before an allergic response is exhibited. Atopic dermatitis is usually manifested prior to the age of six. The classic distribution is the flexural surfaces of the extremities. Herpes zoster presents with prodromal neuralgic pain two to three weeks prior to outbreak. The rash has vesicles and erythema in a dermatomal distribution that crust over after three to five days. The pain may last after resolution of the lesions. Presentation of tinea corporis is pruritic, annular scaling patches that enlarge with central clearing.
An 8-year-old male presents to his primary care provider with the onset of a new rash, consisting of small, oval, discrete scaling plaques on his trunk, and a large red plaque with overlying thin, silvery scales in the gluteal cleft. Which of the following is a potentially important historical finding in this patient?
This is a classic guttate psoriasis. An acute strep infection is a known precipitating factor of guttate psoriasis. All patients need to be checked and treated for a strep infection. Atopy has no correlation with guttate psoriasis. It is not caused by contact with an allergen or irritant. It is also not caused by an allergic reaction.
A 30 year old male presents with bright red erythema over her cheeks and nose after spending a week at the beach. She has had no prior rashes. She states that the rash is pruritic and she has had a low grade fever accompanied by lethargy. Lab results show a (+) ANA and anti DS-DNA with an elevated ESR. What is the most likely diagnosis?
This is a classic presentation of systemic lupus erythematosus (SLE). This autoimmune disorder is more common in women who are in their 20s or 30s. Frequently it is precipitated or worsened by sun exposure.
A mother presents with her four-month-old infant for a well child check. While examining the child, you notice ill defined bluish macules on the back and lumbosacral regions. What is the appropriate next step?
This is a common presentation of hypermelanosis, sometimes commonly referred to as Mongolian spots. These usually occur in patients with more pigmented complexions. They usually spontaneously resolve prior to the child entering grade school. Hypermelanosis can sometimes be mistaken for child abuse by an inexperienced practitioner; however, hypermelanosis is a common benign condition that occurs in patients with pigmented skin. There is no increased incidence associated with hypermelanosis, and no treatment is required or available.
An 8-year-old female presents with numerous discrete, skin colored papules with a central umbilication. The lesions are mildly pruritic. What is the most likely diagnosis?
This is classic presentation of Molluscum contagiosum. Molluscum primarily affects younger children, from infancy through elementary age. Lesions appear as pearly, skin colored papules with a central umbilication. They can be pruritic. Herpes simplex virus is described as a vesicle that crusts after a few days. Neurogenic pain is associated with the outbreak. The varicella zoster virus is chicken pox. These lesions are described as "a dew drop on a rose petal," due to the characteristic vesicle on a red base. They occur in crops, with some being vesicular and some being crusted. There is no umbilication. Comedonal acne primarily affects teens. These lesions are located on the face, back, and chest.
A 62-year-old female diabetic patient complains of a pruritic rash under her breasts. A physical exam shows an eroded red plaque with satellite papules. What is the most likely cause?
This is consistent with a yeast infection of the skin, caused by Candida albicans. Diabetic patients are particularly susceptible to these infections. A staph infection of the skin will have either honey colored crusting or inflammatory papules and pustules with erythema of the skin. A strep infection of the skin will have inflammatory papules and pustules with erythema of the skin. A herpes simplex infection will have vesicles that crust over after a few days. There is often preceding neurogenic pain prior to the outbreak.
A 6-year-old male presents with multiple lesions on his shins. The lesions are annular dermal plaques with a central depression. There are no epidermal changes. He states the lesions are asymptomatic. The child has no other medical problems and is a normal active child. What is the most likely diagnosis?
This is the classic distribution of granuloma annulare. These lesions commonly occur over bony surfaces and are thought to be secondary to minor trauma (such as playing soccer, normal play activities, or insect bites). The lesions will spontaneously resolve and no treatment is indicated. The distribution in this patient is similar to that of classic necrobiosis lipoidica; however, the dermal changes are classic for granuloma annulare. Necrobiosis lipoidica starts as brown-red plaques that evolve to become waxy appearing. They are commonly misdiagnosed as tinea corporis; however, there are no epidermal changes such as scaling. The lesions are completely dermal. Atopic dermatitis in a 6-year-old child is most commonly distributed on the flexural surfaces and consists of red scaling plaques that are pruritic.
A 7-year-old presents with vesicles withsurrounding erythema, located on the sides of his fingers and toesand in his mouth. He has a low-grade fever and has difficulty eating,secondary to pain. What is the most likely cause of this rash?
This is the classic eruption of hand-foot-and-mouth (HFM) disease,which is caused by the Coxsackie A16 virus. HFM is highly contagious.Patients will present with painful ulcerative lesions, which maymake it difficult to eat. There are also vesicles on the hands and feetthat are relatively asymptomatic. HFM may be associated with a low-gradefever, malaise, abdominal pain, and respiratory symptoms.
A 30 year old female complains of a dome shaped slightly erythematous nodule on her right thigh. Upon clinical examination it exhibits the "dimple sign". The patient states the lesion is not changing and is asymptomatic. What is the most likely diagnosis?
This is the classic presentation of a Dermatofibroma. The dimple sign is when a depression forms after the lesion is laterally compressed between the fingers
A 22-year-old complains of a spreading rash. He states it began about a week ago, with one large spot on his abdomen. Very shortly thereafter, the rash rapidly spread on his torso. The lesions are small oval red plaques with a collarette of scale. He states they are only mildly pruritic. What is the most likely diagnosis?
This is the classic presentation of pityriasis rosea. The large initial lesion is the herald patch. The ensuing lesions are small, oval, and have a collarette of scale. The lesions are distributed along Blaschkoe's lines, which is the "Christmas tree" distribution. Presentation of tinea corporis is pruritic, annular scaling patches that enlarge with central clearing. Guttate psoriasis presents as salmon-pink papules or small plaques with overlying fine silvery scales. Atopic dermatitis is usually manifested prior to the age of six. The classic distribution is the flexural surfaces of the extremities.
A 25-year-old female presents for a skin exam. She has no family history of skin cancer, and has no moles that itch, bleed, or ulcerate. She is concerned about a mole on her arm that is surrounded by a hypopigmented area. She states that the mole appears to be decreasing in size. What would appropriate management of the lesion include?
This lesion is consistent with a halo nevus. The depigmented macule that surrounds the nevus is similar to vitiligo and may consume the nevus; therefore, reassurance that this will resolve is appropriate for this patient. There is no need for excision with margins as this is not indicative of malignant changes. Hydrocortisone 2.5% ointment is a low potency topical steroid. This treatment is not indicated for a halo nevus. Ketoconazole is an antifungal used to treat fungal infections. There are no indications of fungal infection in this halo nevus.
The parents of a four-month-old child present with concern regarding a birthmark on the child's scalp and left side of face. The lesion has been present since birth and is growing. It has an orange, pebbly appearance. What is the appropriate treatment?
This lesion is consistent with a nevus sebaceous. It will grow as the child grows. After puberty, the lesion becomes thicker with a warty appearance. There is a slight increase in incidence of basal cell carcinoma as the patient ages. It is recommended that the lesion be excised prior to puberty, when these changes occur in response to hormone secretion. It is confined entirely to the skin; therefore, a CT is not necessary. Laser therapy is not an effective treatment for a nevus sebaceous. It requires complete excision. It also has an increased risk of basal cell carcinoma. It will not spontaneously resolve.
A 28-year-old male presents with a tan-pink, well-demarcated waxy plaque, with raised firm borders located in the pretibial region of the left lower extremity. What is the next appropriate step to confirm the diagnosis?
This lesion is consistent with necrobiosis lipoidica, and is associated with diabetes mellitus. The patient should undergo glucose tolerance testing to be evaluated for diabetes.
An 8-year-old male with a history of atopicdermatitis presents with a widespread rash consisting of vesiclesand eroded lesions. What is the causative organism?
This patient has eczema herpeticum. This is caused by the herpessimplex virus. Transmission can occur innocuously via the parent.Atopic dermatitis is a risk factor for eczema herpeticum, secondaryto the impaired barrier function of the skin. This impaired barrier functionallows the virus to spread rapidly.
A 78-year-old Caucasian female has a 3-year history of stiffness and achiness of bilateral shoulders and hips. She has been tested for rheumatoid arthritis in the past and has been found negative. Multiple radiographs of her hips and shoulders are unremarkable. She admits that she was placed on prednisone for an allergic reaction and noted a temporary resolution of her symptoms. For the past two weeks she complains of increasing symptoms now involving her neck and pain in her jaw with chewing. Today she noticed that her scalp is sore when she brushed her hair on the right side. What is the most feared complication of this condition that may be prevented with prompt diagnosis and treatment?
This patient has long standing symptoms of PMR with current symptoms suggestive of giant cell (temporal) arteritis. Visual loss is the most feared complication of temporal arteritis, but it can be prevented by prompt initiation of high-dose prednisone. PMR often occurs with or prior to development of temporal arteritis and is not considered a complication. Large vessel involvement--which may result in choices (B), (C), and (D)--is less common than temporal artery involvement in GCA. The patient does not have symptoms of large vessel involvement.
A mother presents with a four-month-old male infant complaining of a dry, itchy rash that never seems to completely resolve. There are days when it appears to improve. She currently uses baby wash and baby lotion to care for his skin. She recently discontinued the lotion because he screams when it is applied. Which of the following is this condition exacerbated by?
This patient has the classic presentation of infantile atopic dermatitis. There are numerous factors that can irritate this condition including frequent (more than once a day) or long baths, soap based cleansers, cold dry environments, illness, stress, itchy clothing, and allergies. Lotions may sting, especially if the skin is dry and the skin barrier is broken. Atopic dermatitis usually improves in warm, humid environments. Petroleum based moisturizers are an important part of the treatment of atopic dermatitis. Soap free cleansers are recommended for patients with atopic dermatitis, as they are less irritating and drying. Topical steroids are the first line treatment of atopic dermatitis.
Parents present with their 8-month-old childwith complaints of a new rash. This rash appears as monomorphic,flat, and red papules, some of which coalesce to form plaques. Theyare present on the face, buttocks, and extremities. What is theappropriate management of this condition?
This patient has the rash of Gianotti-Crosti. It is also calledpapular acrodermatitis of childhood. This rash starts with classicmonomorphic, flat, and red papules that coalesce to form plaques.It is symmetric in its distribution and classically affects theface, elbows, and knees. It will resolve on its own; therefore,no treatment is necessary.
A 12-year-old male presents with hyperkeratoticpapules located on both hands. What is the causative organism?
This patient has verruca vulgaris orthe common wart. The causative organism is the human papillomavirus(HPV). They can affect patients of any age and can occur on anyskin surface. There is a predilection for the hands and fingers.
A 4 year old male presents with a fever for 3 days. His highest temperature was 39.4C. His mother brings him to the ED because she noticed this morning that his palms and soles were red. Now, there is blotchy erythema on the trunk with bulbar conjunctivitis and diffuse erythema on the tongue and prominent papillae. CBC shows leukocytosis. What is the appropriate management of this patient?
This patient is exhibiting classic signs and symptoms of Kawasaki Disease. Complications of Kawasaki Disease include coronary artery aneurysms, myocarditis, myocardial ischemia or infarction, and stroke. Recommended treatment is hospitalization to monitor for complications and administration of IvIg with aspirin.
An 18-year-old male presents with a rashconsisting of erythematous target-like lesions on his arms. Physicalexam shows a healing cold sore on his lips, but no other skin or mucosallesions are present. What is the most likely cause?
This patient is exhibiting the classic rash of erythema multiformeminor. Etiology of this disorder can be traced to herpes simplexoutbreaks or other viral or bacterial infections. Recurrent diseaseis most often associated with herpes simplex outbreaks.
A 14-year-old female presents with a 24-hour history of episodic outbreaks on her hands and feet. She describes the outbreaks as beginning on the sides of her fingers and toes, with small intensely pruritic vesicles. What should be the next step in treatment?
This patient is experiencing probable dyshidrotic eczema. It is necessary to rule out a secondary bacterial infection, so a bacterial culture is necessary. It is also necessary to rule out a fungal infection or parasitic by performing a KOH. This does not have any features of a viral infection, so a viral culture is not necessary. A punch biopsy is also not necessary because it can be diagnosed with a non-invasive procedure. A shave biopsy is not indicated because non-invasive techniques can be used to diagnose. Shave biopsies are not indicated when vesicles are present.
A 6-year-old male presents with crusted erythematous lesions on the nose, mouth, and chin. He has a history of atopic dermatitis. Which of the following should be part of an appropriate treatment regimen?
This patient is suffering from impetigo. Impetigo is easily treated with a topical antibiotic, such as mupirocin. Hydrocortisone is a topical steroid and may worsen the infection. Lotrisone is a combination medication that includes an antifungal and a topical steroid, neither of which is indicated in this patient. Ketoconazole cream is used to treat fungal infections, not bacterial infections.
A 15-year-old obese male presents with annularlyconfigured lesions in a generalized distribution. They are asymptomatic.What can these lesions be associated with?
This patient presents with a generalized form of granuloma annulare(GA). Generalized GA can be associated with diabetes mellitus.
A 15 year old male presents with lesions on his palms, dorsum of his hands and lower arm. They began as red macules that developed a central vesicle of a few days. The lesions are pruritic with no other symptoms. What is the most common etiology?
This patient presents with the classic iris or target lesion of erythema multiforme (EM). The most common cause of recurrent EM is herpes simplex outbreak which usually precedes EM by a few days.
A six-month-old male has recurrent diaper rashes, which are not responding to ketoconazole cream or zinc oxide diaper creams. Physical exam shows well demarcated perianal erythema, with scattered red papules on the buttocks. A KOH is negative. What would appropriate management include?
This rash is consistent with a perianal staph or strep infection. This bacterial infection is easily treated with topical mupirocin. If the rash does not resolve after two weeks of topical treatment, treatment with an oral antibiotic such as Keflex is usually successful. Treatment with a topical steroid may worsen the infection. Tretinoin is a topical retinoid indicated to treat acne, and is not appropriate for this patient. Lotrisone is a combination medication that includes an antifungal and a topical steroid, neither of which is indicated in this patient.
A 16-year-old male complains of a recurrent rash that is noticed each year during the summer. He states that the rash is asymptomatic but is spreading. A physical exam shows small hypopigmented macules with fine scale. A KOH exam shows budding yeast. What is the most likely diagnosis?
Tinea versicolor is a yeast infection that primarily affects teens and young adults. The area of infection is usually the upper back, upper chest, and lower face. It occurs in warm, humid environments and can recur yearly. The appearance of the infection can be hypo- or hyper-pigmented, slightly scaling macules. The characteristic microscopic appearance on a KOH is described as "spaghetti and meatballs," due to the shortened hyphae and spores of the yeast. Atopic dermatitis in a teen patient would normally be described as red scaling plaques that affect the flexural surface. Atopic dermatitis is also described as being pruritic. Post inflammatory hypopigmentation occurs following an inflammatory reaction on the skin. The hypopigmentation is not scaling and will have a negative KOH. Tinea corporis can be hypopigmented and scaling, but usually exhibits central clearing and pruritis. It does not recur seasonally and affects exposed surfaces. A KOH will show branching hyphae and spores.
Dysfunction of Eustachian Tube
Tube that connects the middle ear to the nasopharynx. When compramised, air becomes trapped in the middle ear causing negative pressure, usually results from viral URI or allergies. Presents with aural fullness, fluctuating hearing, discomfort with barometric pressure changes. Yawning or swallowing may elicit a pop or crackle. Retraction and decreased mobility of TM is present. Tx with forced autoinflation (unless active intranasal infection is present). Use of systemic or intranasal decongestants and oxymetazoline. Prevent with intranasal corticosteroids for allergies. Avoid air travel, altitude changes or driving during active disease.
Pain, decreased hearing and bloody drainage from the ear after a recent diving trip is the most likely what diagnosis?
Tympanic membrane perforation due to barotrauma
Bacterial Keratitis
Type of Corneal Ulcer commonly seen in people who wear contacts while sleeping, or following trauma or surgery. MC pathogens are pseudomonas, pneumococcus, Moraxella and staph. Has hazy cornea with central ulceration and hypopyon. Tx with high concentration topic antibiotics (typically quinolones) for 48 hours. Add aminoglycoside if quinolone resistance is prevalent in the area.
Herpes Zoster Ophthalmicus
Type of Corneal Ulcer that frequently involves ophthalmic division of the trigeminal nerve. Patients present with malaise, fever, HA, and periorbital burning and itching. Symptoms may precede eruption by a day or more. Rash is vesicular, then pustules develop which quickly crust. Lesions of the tip of the nose or lid margins predict eye involvement. Ocular symptoms include conjunctives, Keratitis, episcleritis, anterior uveitis, elevated intraocular pressure. HIV is a strong risk factor. Tx with high dose acyclovir, valacyclovir, or famciclovir started within 72 hours of rash presentation reduces ocular complications and postherpetic neuralgia.
Herpes Simplex Keratitis
Type of Corneal Ulcer that has recurrent cases that may be observed with colonization of trigeminal ganglion. Dendritic (branching) ulcer is characteristic. Tx with debridement, patching, topical antivirals. Consider long term oral antivirals in specific populations.

A 14-year-old female patient presents to your family practice clinic having received a 1% total body surface area first and second degree burn to the left forearm. Of the following, what would you recommend for your patient?
Unless a critical surface (face, genitalia or hands) is involved, first and second degree burns may be treated in the outpatient setting. Blisters may be left intact as a physiologic dressing, and deroofed after they rupture. The patient requires tetanus prophylaxis and a topical antibiotic cream, usually either silver sulfadiazine or bacitracin. Sulfadiazine may permanently stain skin, so use it cautiously in potentially exposed skin areas for cosmetic reasons.
Which of the following is a result of untreated or partially treated otitis media, which presents with fever, ear pain, otorrhea, tenderness behind the ear, fluid collection, and destruction of air cells seen on head CT?
Untreated or partially otitis media can result in mastoiditis. Tenderness, redness, and fluctuance over the mastoid bone is characteristic. Peritonsillar abcess symptoms include severe sore throat, drooling, dysphonia, and outpouching of the tonsillar pillar on the affected side and trismus. Ethmoid sinusitis presents with nasal congestion, discharge, and headache. Suppurative otits media is contained in the middle ear, without spreading to adjacent structures.
Corneal Abrasion
Usually a result of minor trauma, such as AZ fingernail, contact lenses, eyelash or small FB. Presents with severe pain and sensation of FB and may be accompanied by photophobia, tearing, injection, and blepharospasm. Record visual acuity BEFORE examination or treatment. Slit lamp or fluorescein stain will reveal defect but a clear cornea. Must search for FB. Tx with topical anesthetics for immediate relief; however, only to assist in confirming Dx, DO NOT PRESCRIBE. ABX ointment, Acetaminophen or NSAIDS for analgesia. Patching for no more than 24 hours, only for large abrasions (>5-10mm), longer than 24hrs retards healing. 1-2 day follow ups are essential.

A 12-year-old presents with sharply demarcated depigmented macules on bilateral knees. The parents report that this began about one year ago, after the child fell and skinned his knees. After healing, he was left with these markings. What is the most likely diagnosis?
Vitiligo is the most likely diagnosis. Vitiligo is an autoimmune disorder that affects the melanocytes. There is often a history of trauma that can precede an occurrence of vitiligo. The course for vitiligo is variable. Sometimes it will resolve spontaneously. Other times, it will continue to progress despite treatment. Post-inflammatory hypopigmentation are areas of lighter pigment, not complete depigmentation, which result from a resolved inflammatory process. The pigment will return over time. A hypertrophic scar is one which is enlarged but stays within the borders of the original injury. No pigment changes are associated with these scars. Pityriasis alba is a yeast infection of the skin, and usually appears on the face. It usually occurs in elementary school aged children, and is more apparent in late summer or early fall.

When bacterial in origin, this inflammatory eyelid condition is usually caused by Staphylococci. Chronic inflammation of the eyelid margins. Caused by seborrhea, strep or Staph infection, dysfunction of the meibomian glands. Anterior involves the eyelid, lashes and nearby glands. May become ulcerative due to infection with sataph, or seborrheic due to seborrhea of the scalp, brows, and ears. Posterior results from meibomian gland inflammation. Staph may also cause infection in the posterior type. Glandular dysfunction in posterior type is strongly associated with acne rosacea.
