Miscellaneous Flashcards
Extraintestinal manifestation of IBD
Pyoderma gangrenosum
Xray findings consistent with mesenteric vascular insufficiency
Pneumatosis intestinalis
Thumb printing
Free air in the peritoneal cavity
Crucial colonic ischemia areas
Griffith’s point: Splenic flexure
Sudeck’s point: Rectosigmoid
Gold standard for diagnosisnof mesenteric vascular insufficiency
Laparotomy
Mainstay of therapy for mild/moderate UC or CD
Sulfasalazine
Steatorrhea is an increase in stool fat excretion by
> 6% of dietary fat
Gold standard for establishing presence of steatorrhea
Quantitative stool fat determination
Malabsorption disorder characterized by chronic diarrhea, steatorrhea and weight loss
Tropical sprue
Nutritional deficiency associated with tropical sprue
Folate and cobalamin
Diagnosis of tropical sprue
Small intestinal mucosal biopsy
Diarrhea + Steatorrhea + MACROCYTIC anemia + proliferation of colonic-type bacteria
Bacterial overgrowth syndrome
Macrolide antibiotic with immunomodulatory properties effective in refractory IBD
Tacrolimus
MC location of colonic diverticula
Sigmoid colon
MC form of acute intestinal ischemia and most prevalent disease complicating cardiovascular surgery
Ischemic colitis
Most feared complication of acute intestinal obstruction
Closed loop
Hallmark of all forms of intestinal obstruction
Abdominal distention
Presence of palpable abdominal mass in the setting of acute intestinal obstruction
Closed loop strangulation
Stepladder pattern and absence of paucity of colonic gas are pathognomonic
SI obstruction
Bird beak on abdominal radio series
Volvulus
First indication of worsening fibrosis in chronic liver disease
Mild thrombocytopenia
Single most reliable lab finding in liver abscess
Elevated alk phos
Inherited disorder of bilirubin metabolism characterized by low grade, conjugated hyperbilirubinemia, usually asymptomatic but worsened by pregnancy or OCPs
Dublin Johnson syndrome
Occasional prodromal serum sickness-like syndrome seen with acute hepatitis B is due to
Immune complex formation and deposition
Most important risk factor for ultimate development of cirrhosis and HCC in both HBeAg reactive and HBeAg-negative chronic Hep B
Level of HBV replication
antiLKM1 positive
Autoimmune hepatitis
Presinusoidal portal hypertension
Schistosomiasis
Frequent, dreaded complication of transjugular intrahepatic portosystemic shunt (TIPS)
Hepatic encephalopathy
Hepatorenal syndrome with worse prognosis
HRS 1
Most important mecanism in the formation of lithogenic bile
Increased biliary secretion of cholesterol
Low levels of pancreatic enzymes in acute pancreatitis may be seen with
Hypertriglyceridemia
Unusual complication of acute pancreatitis manifested by sudden and severe loss of vision
Purtscher’s retinopathy
Watermelon stomach
Antral vascular ectasias
Risk of cecal perforation in colonic pseudoobstruction
Cecal diameter >12cm
Symptomatic hypopharyngeal webs + iron deficiency anemia
Plummer Vinson
Epigastric pain + protein-losing enteropathy +/- occult bleeding + large gadtric mucosal folds
Menetrier’s disease
