Study Notes

Blumberg's Sign

Blumberg's sign, also known as rebound tenderness, is a clinical sign of peritoneal inflammation or irritation.
It's elicited by applying deep pressure to the abdomen and then suddenly releasing the pressure.
A positive sign is sudden pain felt when pressure is released, rather than when pressure is applied.

Trousseau's Sign

Trousseau's sign indicates carpopedal spasm, an involuntary contraction of the hand and wrist muscles.
It is a clinical sign of hypocalcemia, meaning low calcium levels in the blood.

T-Tube

A T-tube is a medical device shaped like the letter "T" used for various purposes, including biliary drainage and airway healing.
After surgery on the common bile duct (CBD), a T-tube is inserted to drain bile and prevent buildup.
T-tubes are typically made of silicone, PVC, latex, or red rubber.
They are used to treat retained stones and help the bile duct heal.
The use of T-tubes for biliary tree injuries is controversial, with some surgeons concerned about the possible leakage of bile after removal.

Other Medications

Lactulose is a laxative and ammonia reducer that treats constipation and liver disease.
Octreotide is an injection medication that treats high growth hormone levels caused by acromegaly, a condition affecting bone and tissue growth.
Spironolactone is a diuretic that treats high blood pressure, fluid retention (edema), and high levels of the hormone aldosterone.
Asterixis, also called flapping tremor, indicates the inability to maintain sustained muscle contraction, resulting in brief, irregular lapses during a sustained posture.

Cholecystitis

Cholecystitis is an inflammatory condition of the gallbladder caused by bile getting trapped within the organ.
It can be acute (sudden onset) or chronic (long-term).
Symptoms include pain in the upper right abdomen or upper middle of the belly, pain that spreads to the right shoulder or back, nausea and vomiting, fever, sweating, loss of appetite, jaundice (yellowing of the skin and whites of the eyes), and a bulge in the abdomen.

Myxedema Coma

Myxedema coma is a rare, life-threatening medical emergency caused by severe hypothyroidism.
It's characterized by a triad of symptoms: altered mental status (confusion, non-responsiveness, or mental slowness), hypothermia (low body temperature), and a precipitating event (such as infection, stroke, or myocardial infarction).
Other symptoms include hypotension, decreased pulse pressure, periorbital edema, enlarged tongue and tonsils, slow respiratory rate, soft or distant heart sounds, abdominal distention, and urinary bladder distention.

Graves' Disease

Graves' disease is an autoimmune disease that causes the thyroid to overproduce thyroid hormone, resulting in hyperthyroidism.
Symptoms include weight loss, bulging eyes (exophthalmos), fast or irregular heartbeat, heat sensitivity, thick, red skin on the shins or feet, changes in menstrual cycles, problems getting an erection, and low sex drive.
Other characteristics include a diffuse goiter (enlarged thyroid gland).
