To study the events that might lead to an increased risk of cholesterol gallstones, we examined biliary lipid composition and secretion and bile acid composition and kinetics at different stages of pregnancy or ovulation in young, nonobese, healthy women. Lipid composition and bile acid distribution were determined in duodenal fluid obtained in the fasting(More)
Impaired gallbladder contraction has been previously shown in diabetes mellitus. In this study gallbladder contraction was measured by real-time ultrasonography in 20 subjects (eight healthy controls and 12 diabetics) studied twice on 2 consecutive days, before and after intravenous metoclopramide injection. Contraction was expressed by fasting gallbladder(More)
Individuals who take contraceptive steroids or estrogens are at increased risk of developing cholesterol gallstones. The mechanisms of the increased stone formation are incompletely understood. In this study we report biliary lipid composition and secretion, bile acid composition and kinetics, and gallbladder function in a group of healthy, nonobese women(More)
BACKGROUND Carbohydrate malabsorption of lactose, fructose and sorbitol has already been described in normal volunteers and in patients with functional bowel complaints including irritable bowel syndrome. Elimination of the offending sugar(s) should result in clinical improvement. OBJECTIVE To examine the importance of carbohydrate malabsorption in(More)
We reviewed retrospectively a cohort of 80 patients with hyperemesis gravidarum hospitalized between 1976 and 1986 for the presence of abnormal liver enzymes and ketonuria. Thirteen (16%) had abnormal liver enzymes, generally less than four times the upper limit of normal. In this group, hyperemesis gravidarum began at the 14th week of pregnancy as compared(More)
Hepatotoxicity has been recently described as a rare complication of sulfasalazine therapy. Two patients with hepatic damage after sulfasalazine treatment are reported. Liver biopsy performed in one patient revealed granulomatous hepatitis. On rechallenge with 5 aminosalicylic acid enema the second patient developed a hypersensitivity reaction without(More)
OBJECTIVES To determine the efficacy and safety of short chain fatty acids (SCFA) in the treatment of refractory distal ulcerative colitis (UC). METHODS Ten patients with distal UC who had failed to respond to rectal and oral therapy with 5-ASA and corticosteroids were treated with twice daily enemas containing sodium acetate 60 mM, sodium propionate 30(More)
We used real-time ultrasonography to study gallbladder kinetics in 11 nonpregnant women, 17 women using steroid contraceptives, and 33 pregnant women. Gallbladder volume was determined after an overnight fast and serially for 90 minutes after a standard liquid meal. After the first trimester of pregnancy, gallbladder volume during fasting and residual(More)
We report a patient with bile duct stone-induced pancreatitis who subsequently developed a large pseudocyst that became infected after endoscopic retrograde cholangiopancreatography (ERCP) was done for extraction of the stones. Percutaneous external drainage allowed control of the infection, but failed to seal the pseudocyst. We then treated the patient(More)
