Study Notes

Endocrine and Metabolic Disorders Summary

Type 2 diabetes is characterized by insulin resistance and β-cell dysfunction, while type 1 diabetes is characterized by destruction of pancreatic β cells.
Obesity is a major risk factor for the development of type 2 diabetes.
Insulin binding to its receptor on target cells results in increased facilitated cellular diffusion of glucose, not glycogen breakdown or gluconeogenesis.
Glycosylated hemoglobin levels (HbA1c) are most helpful in evaluating long-term blood glucose management in patients with diabetes mellitus.
Graves disease is an autoimmune disorder associated with autoantibodies to TSH receptors and characterized by low serum TSH levels, not high levels.
Celiac sprue is a malabsorptive disorder associated with an inflammatory reaction to gluten-containing foods, not megacolon or deficient production of pancreatic enzymes.
An infusion of mannitol would be prescribed to treat cerebral edema, not varices, encephalopathy, or peritonitis.
Patients taking high-dose oral glucocorticoids should be routinely evaluated for peptic ulcer disease due to the risk of excess acid production or gastric mucosal defense destruction.
A clinical finding consistent with a hypoglycemic reaction is tremors, not acetone breath, warm, dry skin, or hyperventilation.
Aldosterone secretion is regulated by the presence of angiotensin II in the circulation, not progesterone, corticoglobulin, or ACTH.
A tumor which results in excessive production and release of catecholamines is pheochromocytoma, not goiter, Conn syndrome, or Cushing disease.

Clinical Gastroenterology Key Points

Hyperuricemia is not associated with hepatic encephalopathy, which is characterized by a range of neuropsychiatric symptoms.
Chronic gastritis is tested for Helicobacter pylori, which causes chronic, superficial gastritis and sets up persistent inflammation in the gastric mucosa.
Jaundice is a common sign of liver disease and is not typically associated with malabsorption syndromes, anemia, or cholecystitis.
Elevated serum lipase and amylase levels indicate pancreatitis, not gallbladder disease, appendicitis, or peritonitis.
Most gallstones are composed of cholesterol, not bile, calcium, or uric acid salts.
Absent bowel sounds indicate a need for urgent surgical consult in the presence of acute abdominal pain and vomiting, as they may indicate functional bowel obstruction.
Esophageal varices are a complication of portal hypertension, often resulting from cirrhosis due to alcoholism or viral hepatitis.
Fecal leukocyte screening is indicated in suspected enterocolitis, not lactose intolerance, laxative abuse, or giardiasis.
A low-protein and high-fiber diet is indicated for patients being treated for hepatic encephalopathy, with a gradual reintroduction of protein as ammonia levels drop.
An elevation in alkaline phosphatase and bilirubin levels suggests a biliary cause of acute pancreatitis, indicating the possibility of biliary disease or obstruction, particularly by gallstones.
The definitive treatment for cholecystitis is cholecystectomy, not lithotripsy of stones, chemical dissolution of stones, or antibiotics and anti-inflammatories.
Premature infants are at greater risk for developing necrotizing enterocolitis, not pseudomembranous colitis, appendicitis, or diverticular disease.

Endocrine Disorders and Diabetes Mellitus

Ultralente insulin is not suitable for acute hyperglycemia treatment.
Type 2 diabetes is characterized by insulin resistance and β-cell dysfunction.
Insulin binding to its receptor on target cells leads to increased facilitated cellular diffusion of glucose.
Glycosylated hemoglobin (HbA1c) levels are crucial for evaluating long-term blood glucose management in diabetes mellitus patients.
Graves disease is an autoimmune disorder associated with autoantibodies to TSH receptors.
Celiac sprue is a malabsorptive disorder linked to an inflammatory reaction to gluten-containing foods.
Mannitol infusion is prescribed to treat cerebral edema.
High-dose oral glucocorticoids increase the risk of peptic ulcer disease.
Tremors are a clinical finding consistent with a hypoglycemic reaction.
Aldosterone secretion is regulated by the presence of angiotensin II in the circulation.
Pheochromocytoma is a tumor resulting in excessive production and release of catecholamines.
