An easy way to memorize the 7 different roles that the kidneys play in human health, medical students all around the world often use a simple and funny mnemonic formula: A WET BED.

• A - controlling ACID-base balance
• W - controlling WATER balance
• E - maintaining ELECTROLYTE balance
• T - removing TOXINS and waste products from the body
• B - controlling BLOOD PRESSURE
• E - producing the hormone ERYTHROPOIETIN
• D - activating vitamin D

Telangiectasia is a condition where blood vessels near the surface of the skin are dilated and cause threadlike lines or patterns on the skin. They are sometimes called spider veins. It can be caused by a variety of conditions such as rosacea or liver disease.

Burrows are tunnels formed in the skin that appear as linear marks. They are a result of an infestation of the skin by parasites such as scabietic mites.

A wheal is a red, swollen mark that is often itchy and changes shape. They usually occur in response to a stimulus like a bug bite or food allergies. They are also known as welts or hives.

A pustule is a small bump on the skin that contains pus. They can be infected but not always, as in the case of pustular psoriasis.

Bullae are fluid-filled sacs that form when fluid is trapped under a thin layer of skin. They are similar to blisters and vesicles except that bullae have a diameter larger than 1 centimeter.

A vesicle is a raised bump less than 1 centimeter in diameter filled with air or clear liquid.

A plaque is a flat-topped, raised lesion larger than 1 centimeter. It is often red, scaly and itchy. Plaques are typically found on the scalp, elbows, and knees.

A tumor is a solid mass on the skin or subcutaneous tissue (under the skin). It is firm and usually larger than 2 centimeters.

A nodule is an elevated bump on the skin that is larger than a papule (greater than 1 centimeter in diameter). It may occur in all layers of the skin including the epidermis, dermis and subcutaneous tissue.

A papule is a raised skin area with no visible fluid and sized up to 1 centimeter in diameter. They have distinct borders and come in a variety of shapes.

A macule is a distinct discoloration of the skin that is flat and smaller than 1 centimeter in diameter. It does not cause a change in skin texture or thickness. Macules are noticed visually.

Grandiosity is a symptom experienced by individuals who have bipolar disorder, during manic and hypomanic episodes. With bipolar disorder, this causes individuals to have extreme mood swings that include emotional lows (depression), and highs (mania or hypomania).

A nasoenteric tube is passed through the nares into the duodenum or jejunum when it is necessary to bypass the esophagus and stomach.

Nasoenteric tubes have a decreased risk of aspiration compared with nasogastric tubes; however, a nasoenteric tube can become dislodged to the lungs, causing aspiration of enteral feedings.
If a client with a feeding tube develops signs of aspiration pneumonia (diminished or adventitious lung sounds [eg, crackles, wheezing], dyspnea, productive cough), the feeding should be stopped immediately and tube placement checked (eg, measure insertion depth, obtain x-ray, assess aspirate pH).

Some facilities use capnography to determine placement; if a sensor detects exhaled CO2 from the tube, it is in the client's airway and must be removed immediately

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing.

Seborrheic dermatitis is a non-contagious skin condition. It leads to scaly patches of skin with oily, dandruff-like flakes, especially on your face and scalp. It is only rarely itchy.

Cushing's syndrome is a disorder caused by the body’s exposure to an excess of the hormone cortisol. Cortisol affects all tissues and organs in the body. These effects together are known as

Cushing’s syndrome can be caused by overuse of cortisol medication, as seen in the treatment of chronic asthma or rheumatoid arthritis (iatrogenic Cushing’s syndrome), excess production of cortisol from a tumor in the adrenal gland or elsewhere in the body (ectopic Cushing’s syndrome) or a tumor of the pituitary gland secreting adrenocorticotropic hormone (ACTH) which stimulates the over-production of cortisol from the adrenal gland (Cushing’s disease).

A rate-limiting enzyme is a key enzyme of which the activity determines the overall rate of a metabolic pathway.

A bone density test uses x-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are tested are in the spine, hip and forearm.

Bone density test results are reported in 2 numbers: T-score and Z-score.

The T-score is the bone density compared with what is normally expected in a healthy young adult of the same sex. The T-score is the number of units—standard deviations—that bone density is above or below the average. T-score >2.5 SD indicates the likelihood of osteoporosis and increased risk of fracture. The diagnosis of osteoporosis by DEXA scan also means that treatment
should be initiated with bisphosphonates, oral daily calcium supplementation, and vitamin D.

The Z-score is the number of standard deviations above or below what is normally expected for someone of the same age, sex, weight, and ethnic or racial origin. Z-score ≤-2 may suggest that
something other than aging is causing abnormal bone loss (consider drugs causing osteoporosis such as corticosteroids). The goal in this case is to identify the underlying problem.

Electroconvulsive Therapy is the induction of a grand mal (generalized) seizure through the application of electrical current to the brain.

Lipoprotein lipase helps breakdown triglycerides into fatty acids and glycerol so they can be absorbed by tissue. A defect in this enzyme leads to type I familial hyperlipidemia, which causes pancreatitis and eruptive xanthomas.

 Enterohepatic circulation involves substances that are metabolized in the liver, excreted into the bile, and passed into the intestinal lumen; there they are reabsorbed across the intestinal mucosa and returned to the liver via portal circulation

Extracorporeal circulation is a procedure in which blood is taken from a patient's circulation to have a process applied to it before it is returned to the circulation

The mesenteric circulation refers specifically to the vasculature of the intestines, whereas the splanchnic circulation provides blood flow to the entire abdominal portion of the digestive system that includes the hepatobiliary system, spleen, and pancreas.

collateral circulation is a network of tiny blood vessels, and, under normal conditions, not open. ... This allows blood to flow around the blocked artery to another artery nearby or to the same artery past the blockage, protecting the heart tissue from injury

Positive symptoms of schizophrenia respond to drug therapy more readily than negative symptoms. The secondgeneration “atypical” nonphenothiazine drugs may be slightly more effective in treating negative symptoms of schizophrenia

Kallmann syndrome is a genetical disorder that prevents a person from starting or fully completing adolescence. It is a form of a group of conditions known as hypogonadotropic hypogonadism.

To distinguish it from other forms of hypogonadotropic hypogonadism, Kallmann syndrome has the additional symptom of a total lack of sense of smell or a reduced sense of smell

The mnemonic to master Kallman syndrome features is : KALMAN

   Color blindness (K sounds like C)
   Anosmia
   Low LH, FSH, Sex hormones → delayed puberty
   Midline defects (cleft palate, cleft lip)
   Ataxia (cerebellar ataxia)
   Nerve deafness

Imaging of Kallman Syndrome

 It is easiest to appreciate the anatomical anomalies present in Kallman syndrome by comparing it to a normal patient.

The normal anatomy of the region consists of the olfactory bulbs (blue arrows) located in the olfactory grooves of the anterior cranial fossa.

The inferior surface of the frontal lobes usually consists gyrus rectus (aka straight gyrus) (R) separated from the medial orbital gyrus (M) by the olfactory sulcus (yellow arrow). These are absent in Kallman syndrome. 

The duodenum has four parts; superior, descending, inferior and ascending part. Together these parts form a 'C' shape, that is usually around 25cm long, and wraps around the head of the pancreas

To rememner the length of these parts use the mnemonic;

"Counting 1 to 4 but staggered":
1st part: 2 inches
2nd part: 3 inches
3rd part: 4 inches
4th part: 1 inch

Diloxanide furoate is the drug of choice for asymptomatic patients with E. histolytica cysts in the faeces. Metronidazole and tinidazole are relatively ineffective.
Diloxanide furoate is relatively free from toxic effects and the usual course is of 10 days, given alone for chronic infections or following metronidazole or tinidazole treatment.

Biphasic pills are forms of COC pills containing two different dose combinations of oestrogen and
progestin usually in packets of 21 or 28 tablet e.g. in 21 active pills, 10 may contain one combination,
while 11 contain another. Examples include Biphasil, Ovanon, and Normovlar

Chvostek’s sign consists of twitching of muscles supplied by the facial nerve when the nerve is tapped about 2 cm anterior to the earlobe, just below the zygomatic arch.

Atopic dermatitis is a pruritic disease of unknown origin that usually starts in early infancy; approximately 85% of cases occur within first year of life. Usually presents with pruritus, eczematous lesions, xerosis (dry skin) and lichenification (thickening of skin)

Tactile or vocal fremitus is the palpable vibration you feel when the patient speaks (says ‘99’).

Assessment of tactile fremitus is used to evaluate airflow and density of underlying tissue. Normally, the thicker the chest wall, the more diminished the fremitus; the lower the voice pitch, the greater the fremitus.

Increased fremitus (low voice pitch): conditions causing fluid or exudates in lungs (e.g consolidating pneumonia, atelectasis, pulmonary fibrosis, pulmonary edema, or pulmonary infarction) and sometimes lung tumor depending on size and mobility.

Decreased or absent fremitus (high pich): air trapping, solid tissue, or decreased air movement (e.g. emphysema, asthma, pleural effusion, pneumothorax, or distal to airway obstruction)

The diagnosis is made by palpation and timing the length of contractions. Repeated vaginal examination will demonstrate a cervix which fails to dilate.

Contractions may be strengthened by rehydration, relaxation (e.g. by epidural anaesthesia), rupture of the membranes and the use of intravenous syntocinon.

Metformin must be withheld before and for 48-hours after injection of IV contrast media - due to the increased risk of renal impairment, metformin accumulation, and lactic acidosis

Group A streptococci and S. aureus are the most common causes of impetigo

Necrotizing fasciitis is commonly associated with varicella infection, where the skin lesions are infected by Streptococcus or Staph

Interstitial Syndromes of the Lung include:
• Sarcoidosis
• Histiocytosis X
• IPF (interstitial pulmonary fibrosis)
• Tumor
• Failure
• Asbestosis
• Collagen disorders
• Environmental
• Dust
• Drugs

Tetracycline is an antibiotic.

Don't take with milk or other things containing calcium, bc will cause chelation and change absorption.

Also: Cholesteramine causes decreased absorption.

Quinidine is an anti-arrythmic drug.

It impairs Warfarin liver metabolism, so increases the amount of active Warfain, thus increasing INR and bleeding risk.

Also may be caused by decreased production of VitK in the gut.

Also: if taken with digoxin, binds to muscle tightly, so causes Dig Tox.

Probenecid inhibits uptake of uric acid in renal tubules.

Used in treatment of gout and to increase the action of penicillin and methotrexane (decrease excretion).

Phenobarbital is a barbituate.

It induces liver P450 enzymes that metabolize Warfarin. Thus, need to take more Warfarin when on this drug.

However, if taken patient off Penobarbital, INR rises, too much Warfarin effect.

Also: cholesteramine causes decreased abosorption.

Also: renal clearance is increased by alkalinization.

Penicillin use increase risk of bleeding when taking Warfarin.

2 possibilities

1) change gut flora, so decrease amt of VitK, so increase action of Warfarin.

2) inhibit liver enzyme responsible for Warfarin metabolism.

Also: cholesteramine causes decreased abosorption.

Also: excretion decreased by Probenecid and salicylate.

Methotrexate is used as chemo,

It can cause gout like symptoms from cell breakdown.

However, the drug is metabolized by xantine oxidase, so dont give with Allopruinol, as that would increase the effects of chemo.

Also: renal excretion decreased by Probenecid and Salicylate.

Lidocaine is given  with epinepherine to vasoconstrict and keept drug local.

Also: in CHF, increased action of the drug because decreased blood flow.

Erythromycin and other macrolides increase risk of bleeding when taking Warfarin. 2 possibilities 1) change gut flora, so decrease amt of VitK, so increase action of Warfarin. 2) inhibit liver enzyme responsible for Warfarin metabolism.

Also: increases Digoxin bioavailability by the above 2 mechanisms and also maybe inhibitin p-glycopritein transport system in kidney for Dig.

Epinephrine is given with lidocaine to vasoconstrict and keep the drug local.

Ditropan is an anticholinergic.

When taken with Amitriptyline, causes abdominal distension and constipation.

Because of a pharmacodynamic interaction : tricyclics inhibit the cholinergic system via a different mechanism.

Digoxin binds to muscle tissue, Vd=400.

If something else binds to muscle tissue, digoxin is displaced, leading to higher blood levels and lower Vd. = Digoxin toxicity. (eg, quinidine)

Also: Can cause increased bleeding if taken with Warfarin.

Also: Cholestyramine causes decreased absorption. Also: Erthromycin increases bioavail by 3 mechanisms.

Warfarin is an anti-coagulant, b/c reduces VitK dependent clotting factor production in the plasma.

It has a narrow therapeutic index: with a little Warfarin, the INR = 2, but with a little more, INR = 6+. Highly bound to plasma (95%).

Too much Warfarin leads to bleeding.

Interactions: Increased bleeding (asprin), GI bleeding (NSAIDS), Impairment of Warfarin metabolism and increased bleeding (Quinolone or phenytoin), increased bleeding, maybe bc less VitK (sulfa drugs). Bartituates like phenobarbital increase metabolism, so need more Warfarin.

Also: cholesteramine causes decreased abosorption.

Cholestyramine is an ion exchange binding resin. Used to lower cholesterol by disrupting enterohepatic circulation. It is a charged molecule, so it just sticks to the wall and blocks cholesterol absorption. Will also block the absorption of other drugs (decreased bioavail): such as digitalis, Warfarin, phenobarbitol, tetracycline, penicillin.

Calcium is found in milk etc. Ion, so can cause chelation. Ion binds to drug, gets trapped inside drug in a wierd shape.

It changes absorption of the drug (eg, Tetracycline).

Asprin works by inhibiting platlet function/ anti-thrombosis/ decreases vasoconstriction. 

Pharmacokinetic: Also, is highly bound to plasma (99%), so displaces Warfarin, leading to increased levels of Warfarin that is active. Therefore increases bleeding if taken with Warfarin.

Also: decreases renal excretion of Penicillin and Methotrexate by competing for the transport mechanism.

Amitriptyline is a tricyclic antidepressant. If taken with Ditropan (an anticholinergic), causes abdominal distension and constipation. Because of a pharmacodynamic interaction: tricyclics inhibit the cholinergic system also via diff mech. Also: tricyclics affect membrane pump that moves nts and antihypertensive drugs into intracellular storage sites. So may alter anti-HTN treatments. Also: metabolized via CYP 2D6, inhibited by Prozac.

Allopurinol is used in gout, xanthine-oxidase inhibitor. Xanthane-oxidase creates uric acid, but also metabolizes methotrexane. So, dont give this with methotrexane, even though it might be tempting to decrease gout symptoms in chemo. Also: Increased absorption if taken with iron.

Alcohol Induces cytochrome 2E1, increasing acetaminophen toxicity.
