Study Notes
Gallbladder Stones and Associated Conditions
- Radiolucent stones with 10-20% opacity due to calcifications are typically cholesterol stones.
- The most common complication of gallbladder stones is cholecystitis.
- Cholesterol stones have a higher incidence in populations with obesity and diabetes.
- Risk factors for gallbladder stones include obesity, rapid weight loss, pregnancy, and certain diets.
- Stones associated with infection and chronic hemolysis are pigment stones.
- Ultrasound is the primary imaging modality for diagnosing gallbladder stones.
- Treatment for symptomatic gallbladder stones often involves cholecystectomy.
Cholecystitis and Related Symptoms
- Cholecystitis is characterized by biliary colic, nausea/vomiting, and dull right upper quadrant (RUQ) pain.
- Radiopaque stones are associated with calcium bilirubinate and hemolysis.
- Potential complications from gallbladder stones include acute pancreatitis and acute cholangitis.
- Cholecystokinin, a hormone, triggers gallbladder contraction after a fatty meal.
- Elevated alkaline phosphatase levels are often found in cases of gallstones in the common bile duct.
- The most common type of cholecystitis is acute cholecystitis.
- Murphy's sign is observed during palpation of the RUQ in cholecystitis cases.
Diagnostic Imaging and Complications
- Diagnostic imaging for visualizing the gallbladder and diagnosing cholecystitis includes ultrasound and HIDA scan.
- A fistula between the gallbladder and the gastrointestinal tract can lead to gallstone ileus, causing obstruction at the ileocecal valve.
- A calcified gallbladder due to chronic cholecystitis is known as porcelain gallbladder.
- Ascending cholangitis, an infection of the biliary tree, is also called acute cholangitis.
- The classic triad of cholangitis consists of jaundice, fever, and right upper quadrant pain.
- Gallstone ileus exhibits radiographic findings of pneumobilia, small bowel obstruction, and a gallstone.
Multiple Choice Test Insights
- The key in a multiple-choice item is the correct answer that aligns with the question stem.
- Short-answer and essay tests better assess higher-order thinking skills.
- The strongest predictor of overall student performance is formative assessments.
- A significant disadvantage of multiple-choice tests is the potential for random guessing by students.
- A method to reduce random selection effects includes using a higher number of distractors.
- Misunderstandings about multiple-choice questions often relate to the perception of guessing and answer changes.
Thyroid Development and Ectopic Sites
- The thyroid structure arises from the floor of the primitive pharynx and descends into the neck.
- The normal remnant of the thyroglossal duct is known as a thyroglossal duct cyst.
- Ectopic thyroid tissue may persist as cysts or as the pyramidal lobe of the thyroid.
- The most common site for ectopic thyroid tissue is the base of the tongue.
- Removal of a lingual thyroid may lead to hypothyroidism due to the loss of functional tissue.
