Type 1 diabetes

*Cause*: autoimmune destruction of beta cells in the pancreas, causing insulin to not be able to produce. Fat breakdown produces ketones which can cause diabetic ketoacidosis *Treatment*: insulin: pump or multiple daily injections (3-4/d between basal and bolus). Rapid- and long-acting insulins are preferred over short- and intermediate-. Start at TDD of 0.6 U/kg/d Carbohydrate counting: recommended. Prandial (mealtime) insulin is dose adjusted based on number of carbs eaten. 1 carbohydrate serving = 15 g [small piece of fruit, slice of bread, 1/3 cup rice/pasta, or 1/2 cup oatmeal *Initiating insulin*: start a basal-bolus regimen with Lantus and Humalog 1. Calculate TDD 2. Divide TDD into 50% basal, 50% bolus 3. Divide bolus insulin among 3 meals

Rigid or tense muscles Absence: momentary loss of awareness. Generalized seizure with non-motor symptoms Focal: start on one side of the brain Focal aware: focal with no loss of consciousness. Used to be known as simple partial seizure Focal seizure with impaired awareness: focal with loss of consciousness. Used to be known as a complex partial seizure Generalized: start on both sides. Loss of consciousness Status epilepticus: seizure lasting longer than 5 minutes *Diagnosis*: EEG *Chronic seizure management*: Non-drug: marijuana.

Started at 0.1 - 0.2 U/kg/d or 10 U/d. Dose is titrated once or twice a week until pt is at fasting blood glucose goal

Cystic Fibrosis

*Cause*: mutation in the gene for the protein CFTR (Cystic Fibrosis Transmembrane conductance Regulator; most common mutation is homozygous F508del mutation), causing an abnormal transplant of chloride, bicarbonate, and sodium, leading to thick viscous secretions. The thick mucus affects the lungs, pancreas, liver, and intestines, which causes difficulty breathing, lung infections, and digestive complications *Symptoms*: salty tasting skin, poor growth, poor weight gain, steatorrhea (fatty stools), malnutrition *Diagnosis*: "sweat test." Usually diagnosed by 2 yo *Intermittent infections*: early stages of disease: most commonly due to staph aureus and h. influenzae Adolescents/adults: pseudomonas (treat with 2 IV drugs to provide potential synergy and prevent resistance. Aminoglycosides recommended. Doses tend to be larger than normal) Chronic: inhaled antibiotics for chronic pseudomonas (28d on therapy, 28d off). Azithromycin not recommended *Treatment order*: order is very important. All inhaled (vitamin supplementation also essential, many will end up requiring insulin) 1. Bronchodilator (albuterol): opens the airways 2. Hypertonic saline (HyperSal): mobilize mucus to improve airway clearance 3. Dornase alfa (Pulmozyme): thins mucus to promote airway clearance 4.

Tremor, Rigidity, Akinesia/bradykinesia, Postural instability Initial: tremors on one-side Additional: micrographia, shuffling walk, muffled speech, drooling, dysphagia, dpression, anxiety, constipation, incontinence *Treatment*: goal is to reduce "off" periods (periods where drug isn't working and disease worsens) and limit dyskinesias Primary: replace dopamine. Give a precursor to dopamine that becomes dopamine in the brain (levodopa). Give dopamine agonist. Sinemet sometimes works better as initial treatment in elderly. Centrally-acting anticholinergic can be used for younger pts *Can cause*: depression: SSRIs, TCAs (preferably secondary amines) Psychosis: quetiapine preferred due to low risk of movement disorders, but it can cause metabolic complications. Clozapine has a high risk of agranulocytosis and seizures

Variceal bleeding cause and treatment

Antiplatelet therapy (commonly ASA) recommended *AE*: HTN Premature closure of ductus arteriosus: before birth, this connects pulmonary artery to aorta, allowing oxygenated blood to flow to the baby, bypassing immature lungs. It closes on its own after birth, if not, IV NSAIDs (indomethacin, ibuprofen) can be used within 14d of birth to help it close Nausea: take wc to avoid Renal dysfunction: will worsen it if patient has liver toxicity *CI*: renal failure (avoid or use cautiously), uncontrolled HTN (avoid), third trimester of pregnancy

PDE5 inhibitors

*MOA*: blocks PDE5 from degrading cGMP, causing smooth muscle relaxation and pulmonary vasculature relaxation & vasodilation *Use*: PAH and sexual dysfunction (does not increase libido) *Dose*: decrease starting dose by 1/2 if ≥ 65 yo, using an alpha-blocker, using a CYP3A4 inhibitor, severe renal or liver disease *AE*: hearing loss, vision loss (may be due to NAION), priapism (seek medical help if > 4h), HoTN, HA, impaired color discrimination, chest pain (seek medical help immediately), flushing, dizziness, dyspepsia, back pain, dysphagia *CI*: nitrates or riociguat *DDIs*: alpha blockers: use with caution. Patient must be stable on alpha-1 blocker before starting PDE5 inhibitor Antihypertensive drugs: use caution Moderate and strong CYP3A4 inhibitors: use lower starting dose

How many mmol are in a mEq?

1 for monovalent ions (Na+, K+). 0.5 for divalent ions (Ca++)

Interpreting arterial blood gases

1. *Acidosis or alkalosis?* Based on pH 2. *Look at other values and see which match with pH*: respiratory: decreased CO2 (alkalosis). Increased CO2 (acidosis) Metabolic: increased HCO3 (alkalosis). Decreased HCO3 (acidosis) Example: low pH = acidosis. If patient had high CO2 and normal HCO3, this matches with respiratory acidosis 3. If both HCO3 and CO2 are abnormal, they usually go in different directions from pH due to compensation so just go with the one that matches pH

Normal potassium is 3.5 - 5.5, becomes concerning when >5. Most abundant intracellular cation. Renal potassium excretion is increased by aldosterone and diuretics (loop > thiazides). If an increase in potassium occurs due to a large meal, insulin will be released which will cause potassium to shift into the cells

Occurs when the heart is not able to supply sufficient oxygen-rich blood because of impaired ability to fill or eject ventricle *Causes*: usually due to MI or long-standing HTN *Patho*: during low cardiac output, blood volume is increased or force of speed of contractions are increased Main pathways: neurohormones that normally balance these systems (e.g. natriuretic peptides) are insufficient RAAS (Renin Angiotensin Aldosterone System. AngII causes vasoconstriction. Aldosterone causes sodium and water retention), SNS (Sympathetic Nervous System), and vasopressin (increases heart rate, contractility [positive inotropy], and vasoconstriction) *Diagnosis*: symptoms associated with fluid overload (SOB, edema), ECHO, and EF (<40% indicates systolic dysfunction or HFrEF [Heart Failure with reduced Ejection Fraction]) Labs: increased BNP, increased NT-proBNP Left-sided S&S: orthopnea, PND, bibasilar rales, S3 gallop, and hypoperfusion General S&S: dyspnea, cough, fatigue Right-sided S&S: peripheral edema, ascites, JVD, HJF, and hepatomegaly

Comminution

Reduce particle size by grinding, crushing, milling, or vibrating *Main methods*: trituration: mixing product thoroughly to make it homogenous. Usually grinding tables in a mortar and pestle until a fine powder is achieved or shaking a liquid emulsion Levigation and spatulation: levigation involves triturating the powder with a mortar and pestle by incorporating a small amount of liquid (levigating agent or wetting agent) to help with grinding process.

Adrenal suppression Other: buffalo hump, osteoporosis, impaired wound healing *Immunosuppressed*: pt becomes immunosuppressed if using ≥ 2 mg/kg/d or ≥ 20 mg/d x >2w. They cannot receive live vaccines. Due to HPA axis suppression, the steroid will need to be tapered slowly to allow the adrenal gland to resume normal cortisol production. Immunosuppression can lead to re-activation of TB, HepB, & HepC, viral infections which can be prevented by a live vaccine prior to start of therapy, lymphomas & certain skin cancers, and infections *Monitoring*: bp, weight, appetite, mood, growth (children), bone mineral density, blood glucose, electrolytes, IOP (if >6w), infection
