Acute Fatty Liver of Pregnancy (AFLP) For
Acute fatty liver of pregnancy (AFLP) is a rare but life-threatening obstetric emergency that occurs exclusively in the third trimester of pregnancy (typically between 30-38 weeks gestation), characterized by microvesicular fatty infiltration of hepatocytes leading to acute liver failure.
Start
Acute Mesenteric Ischemia
Acute mesenteric ischemia (AMI) is a vascular emergency caused by sudden reduction or cessation of blood flow to the small intestine and/or colon, resulting in intestinal ischemia, infarction, and potentially fatal bowel necrosis with peritonitis and sepsis.
Start
Boerhaave Syndrome
Boerhaave syndrome is a transmural perforation of the esophagus caused by a sudden, dramatic increase in intraesophageal pressure against a closed glottis, most commonly occurring during forceful vomiting or retching.
Start
Budd-Chiari Syndrome
Budd-Chiari syndrome (BCS) refers to hepatic venous outflow obstruction occurring anywhere from the small hepatic venules to the junction of the inferior vena cava (IVC) with the right atrium, excluding obstruction caused by cardiac disease or sinusoidal obstruction syndrome (formerly known as…
Start
Carcinoid Syndrome
Carcinoid syndrome is a clinical constellation of symptoms caused by the systemic release of vasoactive substances -- primarily serotonin (5-hydroxytryptamine/5-HT), histamine, kallikrein, prostaglandins, and tachykinins -- from neuroendocrine tumors (NETs, formerly called carcinoid tumors).
Start
Celiac Crisis
Celiac Crisis: historical RN/RPN lesson restored from legacy corpus.
Start
Cholecystitis
Cholecystitis results from gallstone impaction in the cystic duct causing bile stasis, gallbladder distension, and inflammation.
Start
Esophageal Variceal Hemorrhage
Esophageal varices develop as a consequence of portal hypertension, most commonly from hepatic cirrhosis.
Start
Gastrointestinal System Advanced
Gastrointestinal hemorrhage is classified as upper (proximal to the ligament of Treitz) or lower (distal), with upper GI bleeds most commonly caused by peptic ulcer disease, esophageal varices, and Mallory-Weiss tears.
Start
Hepatitis: Viral Types and Liver Function
Viral hepatitis involves inflammation and necrosis of hepatocytes caused by hepatotropic viruses (A through E).
Start
Hepatopulmonary Syndrome
Hepatopulmonary syndrome (HPS) occurs in patients with liver disease when pulmonary capillaries dilate abnormally (from 8-15 micrometres to 15-500 micrometres).
Start
IBD: Crohn Disease Vs Ulcerative Colitis
Inflammatory bowel disease (IBD) encompasses two chronic, relapsing conditions: Crohn disease (CD) and ulcerative colitis (UC).
Start
Liver Cirrhosis
Cirrhosis is the end-stage of chronic liver disease characterized by irreversible replacement of normal hepatic parenchyma with fibrous scar tissue and regenerative nodules.
Start
Mallory-Weiss Tear
A Mallory-Weiss tear is a longitudinal mucosal laceration at the gastroesophageal junction (GEJ) or gastric cardia caused by sudden increases in intra-abdominal pressure against a closed glottis, most commonly from forceful retching or vomiting.
Start
Portal Vein Thrombosis
Portal vein thrombosis (PVT) involves partial or complete obstruction of the portal vein by thrombus, disrupting hepatic portal blood flow.
Start
Primary Biliary Cholangitis
Primary biliary cholangitis (PBC, formerly primary biliary cirrhosis) is a chronic autoimmune liver disease characterized by progressive destruction of small intrahepatic bile ducts by T-cell-mediated granulomatous inflammation.
Start
Primary Sclerosing Cholangitis (PSC)
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by progressive inflammation, fibrosis, and stricturing of the intrahepatic and extrahepatic bile ducts, leading to bile duct obliteration, secondary biliary cirrhosis, and liver failure.
Start
Superior Mesenteric Artery Syndrome
Superior mesenteric artery (SMA) syndrome is a rare vascular compression disorder in which the third portion of the duodenum is compressed between the SMA anteriorly and the aorta and vertebral column posteriorly.
Start
Whipple Disease
Whipple disease is a rare, chronic systemic infection caused by Tropheryma whipplei, a gram-positive actinobacterium that infects macrophages throughout the body.
Start
Wilson Disease
Wilson disease is an autosomal recessive disorder of copper metabolism caused by mutations in the ATP7B gene encoding a copper-transporting ATPase in hepatocytes.
Start
Zollinger-Ellison Syndrome
Zollinger-Ellison syndrome (ZES) is caused by gastrin-secreting neuroendocrine tumors (gastrinomas) that produce massive, unregulated gastrin secretion, driving continuous maximal stimulation of parietal cell hydrogen-potassium ATPase pumps and causing gastric acid hypersecretion.
