Bile duct abnormalities in the acquired immune deficiency syndrome.
Pathological changes in the liver have been described in patients with acquired immune deficiency syndrome; however, lesions of the bile ducts have not been noted. We report 2 patients with intrahepatic bile duct abnormalities, one having sclerosing cholangitis of the large ducts. We discuss the possibility that these changes are secondary to opportunistic infection or are induced more directly by immunologic mechanisms.

Whipple's disease, successful response to sulfamethoxazole-trimethoprim.
Because of allergy to penicillin and intolerance to tetracycline, a 47-year old man, known to have Whipple's disease, was treated with sulfamethoxazole-trimethoprim, one tablet two times a day for six months. The patient has remained in remission one year after medication was discontinued. Sulfamethoxazole-trimethoprim may be the treatment of choice for Whipple's disease.

Hepatic abscess due to Yersinia enterocolitica without bacteremia.
A 71-yr-old diabetic patient was evaluated because of right upper quadrant pain. He was found to have a large hepatic abscess secondary to Yersinia enterocolitica infection. He lacked clinical evidence of bacteremia or gastrointestinal infection. It is postulated that Yersinia enterocolitica reached the liver through the portal system from an inapparent intestinal infection. This is the first reported case of a liver abscess secondary to Yersinia enterocolitica without evidence of systemic infection.

Asymptomatic primary biliary cirrhosis.
Ten asymptomatic patients with biochemical, immunologic, and histologic features of primary biliary cirrhosis are described. Their liver disease was first suggested by an elevated alkaline phosphatase level upon routine biochemical screening tests. Increasing awareness of this disease has led to its increased detection in asymptomatic patients. It is this group of asymptomatic patients from whom we will learn more about the natural history of primary biliary cirrhosis.

Peyronie's disease and sclerosing cholangitis in a patient with ulcerative colitis.
A 51-year-old patient with a 30-year history of ulcerative colitis developed sclerosing cholangitis and later Peyronie's disease. The occurrence of these diseases in the same patient supports the view of an immunological origin of these associated disorders.
Cholangiography↗
Rod-shaped organism in the liver of a patient with Whipple's disease.
Histological review of a liver biopsy from a patient with known Whipple's disease revealed a prominence of Kupffer cells containing PAS-positive granules. Electron microscopy revealed rod-shaped organisms in the Kupffer cells but the presence of these structures were not associated with overt liver injury. This is thought to be the first reported demonstration of these bacillary bodies in this location.

Factitial bleeding: successful management with psychotherapy.
A young female nurse presented with unusual upper and lower-gastrointestinal bleeding, shown to be factitial. Following detection, she was successfully confronted and treated with psychotherapy. A plan for successful management of the Munchausen syndrome is discussed.

Erythromycin ethylsuccinate-induced cholestasis.
A 52-year-old Caucasian female developed abdominal pain, fever, and jaundice after erythromycin ethylsuccinate administration. Similar symptoms followed the administration of the same drug 5 mo earlier. It is believed that this is the first published case of erythromycin ethylsuccinate-induced cholestasis.

Alcohol and liver disease.
It has recently been shown that alcohol may produce liver damage even in the presence of adequate nutrition. Absolute intake, regardless of the type of alcoholic beverage consumed, appears to be the important determinant of whether liver damage will occur. The spectrum of liver injury produced by alcohol includes fatty liver, hepatitis, and cirrhosis. Liver biopsy is necessary for confirmation and to determine prognosis. Therapy includes abstinence, supportive care and nutritional replacement.

Renal response to secretin.
The effect of Jorpes secretin on the urinary volume, pH, and excretion of sodium, potassium, chloride, bicarbonate, titratable acidity, ammonia and phosphate was studied in five healthy male volunteers with and without simultaneous aspiration of duodenal fluids. A three- to fourfold increase in urinary volume and sodium excretion occurred within the first 30 min after secretin injection and this was accompanied by a significant rise in urinary pH in each instance. Urinary bicarbonate excretion increased from 55 plus or minus 13 to 395 plus or minus 33 mueq/30 min after secretin injection. Aspiration of alkaline duodenal contents was accompanied by an even greater postsecretin increase in urinary bicarbonate excretion. No significant changes in arterial pH or blood gases were detected throughout the study. These observations are compatible with a direct effect of secretin upon the renal tubular reabsorption of water, bicarbonate, and other ions, and could account for the transient alterations in urinary pH occurring in response to a meal.
