What is the difference between IPV and OPV?

-OPV(oral poliovirus vaccine) given orally- the live virus can be passed through stool to others; active form of virus! -IPV (inactive poliovirus vaccine) SUB-Q Each vaccine recommended for use against polio had its advantages and disadvantages. The advantage of the OPV was that it was almost 100 percent effective at preventing polio. Also, because the vaccine virus was present in the stool, about 25 percent of people who came in contact with someone who was immunized, would also be immunized (this is called contact immunity). In the early 1960s, when immunization rates in this country were low, contact immunity was an important feature of OPV. However, despite OPV's 40 years of success, there was an extremely rare but frighteningly dangerous side effect: permanent paralysis. The inactivated polio vaccine (or IPV) is now the only vaccine given in the United States to prevent polio

Live-attenuated influenza vaccine (LAIV) contains live attenuated influenza viruses that have the potential to cause mild signs or symptoms related to vaccine virus infection (e.g., rhinorrhea, nasal congestion, fever, or sore throat). LAIV is administered intranasally by sprayer, whereas TIV is administered intramuscularly or intradermally by injection. LAIV is licensed for use among nonpregnant persons aged 2-49 years; safety has not been established in persons with underlying medical conditions that confer a higher risk for influenza complications. TIV is licensed for use among persons 6 months and older, including those who are healthy and those with chronic medical conditions -2 types; both want to be given in October or November -Inactive vaccine mostly given! -LAIV Live attenuated influenza vaccine is a nasal spray; narrower range; so cannot give to children under 5 or asthma, diabetes, or immune compromised patients.

ADH replacement: Diabetes insipidus (DI) is a condition characterized by excessive thirst and excretion of large amounts of severely diluted urine, with reduction of fluid intake having no effect on the concentration of the urine. The most common type in humans is central DI, caused by a deficiency of arginine vasopressin (AVP), also known as antidiuretic hormone (ADH).

When should patients be advised to discontinue ASA and NSAIDs prior to surgery?

What is the primary difference between COX-1 and COX-2 inhibitors?

COX-1 ("Good COX" ) vs. COX-2 ("Bad COX") The most notable difference involves the COX 1 inhibitors' effect on breaking down gastric mucosa. COX 1 inhibitors cause gastric ulceration, while COX-2 inhibitors do not cause gastric ulceration. It is more beneficial to inhibit COX-2 because suppressing the "bad COX" results in more beneficial effects than adverse effects.

Inhibits oxidation, leading to lactic acidosis. Metaformin is not to be used in patients with renal insufficiency (decreases metaformin excretion), who are more prone to increased lactic acid production (liver disease, severe infection, or hx of lactic acidosis), patients who consume alcoold to excess, and pt's with shock and other conditions that can lead to hypoxemia.

What is the MOA of DPP4 inhibitors such as sitagliptin (Januvia)?

Januvia enhances the actions of incretin hormones, endogenous compounds that (1) stimulate glucose-dependent release of insulin, (2) suppress postprandial release of glucagon (a hormone that decreases glucose production in the liver). Both actions keep blood glucose level from climbing too high. So, it inhibits dipeptidyl peptidase 4 (DPP-4), and enzyme that inactivates the incretin hormones.31. Which drugs used to treat DM should be avoided in patients with a history of pancreatitis. Exenatide, Sitagliptin (Januvia)/DPP-4 inhibitors

Methotrexate. This causes fetal death and congenital abnormalities

Give an example of a COX-2 inhibitor that is considered safer than NSAIDs in the causation of gastric ulcers.

Second-generation NSAID, Celecoxib (Celebrex) is considered safer in the causation of gastric ulcers, especially for short term use because it only inhibits COX-2 and does not inhibit COX-1, "the good cox" , that produces the protective gastric mucosa. However, it is important to note, they are more dangerous in other ways; they increase the risk of MI and stroke.

What is the effect of histamine2 receptor stimulation?

Secretion of gastric acid. Histamine acts directly on parietal cells of the stomach to promote acid release.

Severe febrile illness, Severe allergic reaction (e.g., anaphylaxis) after a previous dose or to a vaccine component

Give an example of a patient that would be inappropriate for treatment with radioactive iodine.

Someone under the age of 30 or someone that is pregnant or lactating

What is the name of the gland that regulates calcium balance in the body?

The parathyroid gland

What are the mechanisms by which glucocorticoids interrupt the inflammatory response?

They inhibit synthesis of prostaglandins, leukotrienes and histamine to reduce swelling, warmth, redness and pain.

Why are doses of glucocorticoids discontinued with a drug taper?

They must give the adrenal glands time to learn how to function again on their own; Taper over 7 days (depending on time using the drug), so that adrenal glands can learn again how to make their own glucocorticoids

Name three drug classes that increase blood sugar.

Thiazide diuretics Sympathomimetics Glucocorticoids Antipsychotics Possibly statins

Why are glucocorticoids withdrawn gradually?

Withdrawal of glucocorticoids must be done slowly because you can cause adrenal hormone insufficiencies after the discontinuation of use. You can get a recurrence of the underlying disease as the glucocorticoid is being withdrawn You can also get steroid withdrawal symptoms You can also possibly cause Cushing's syndrome! (www.ncbi.nlm.gov)
