Extrahepatic bile duct obstruction and erosive disruption by cavitating porta hepatis nodal metastasis, treated by uncovered wallstent.

A 45-year-old woman with advanced gastric carcinoma presented with obstructive jaundice. Percutaneous transhepatic cholangiography (PTC) revealed erosive disruption of the extrahepatic bile ducts by a cavitating metastasis in the porta hepatis, as well as a biliary-duodenal fistula. External-internal biliary drainage via the fistula was plagued by recurrent drain occlusion by necrotic debris.

Long-term follow-up of tuberculoma of the brain in an AIDS patient.

Human immunodeficiency virus infection and extrapulmonary TB are defined as AIDS. The clinical manifestations of the TB are related to the interplay of the organism and the host's immune system. A seven-year follow-up of a woman successfully treated for biopsy- and culture-documented tuberculous brain abscess is described.

Rapid oral desensitization to isoniazid and rifampin.

A 45-year-old black woman, sputum positive for acid-fast bacilli, developed hypersensitivity to both isoniazid and rifampin. She was admitted to the hospital and desensitized to both medications using modified penicillin protocols. Skin testing was negative to both drugs.

Occupational tuberculous infections among pulmonary physicians in training.

The invasion of the lower respiratory tract by procedures and support measures such as fiberoptic bronchoscopy, endotracheal intubation, and mechanical ventilation generates respiratory aerosols. These aerosols have a potential for the transmission of tuberculosis and other infections. The follow-up of tuberculin skin test status among staff with exposure to this millieu was observed in hope of delineating whether a significant problem does exist.
