Epidemiological studies on patients with a persistent vegetative state.

Persistent vegetative state after severe brain damage was studied epidemiologically in 110 cases from 1973 to 1976. The causes of brain damage were varied. More than one-third of the cases were due to trauma, and about one-fifth were the result of vascular accidents. Three year observation revealed that 65% of the patients died during this period. Mean survival time for dead patients was 38 months. Reactivity, clinical signs, EEG findings, methods of management, and results of various trials of treatment were investigated in connection with the patient's prognosis.

Treatment of carcinoma of the biliary system.

A series of 23 patients with carcinoma at the hilus of the bile duct were studied. Fourteen of the 23 patients underwent surgical resection. Nine of the 14 patients had a curative resection. Six patients are alive after a follow-up period of five to 25 months. The remaining five patients had noncurative resection, and four of them died from metastatic carcinomas during the next 14 months. One patient who had a left hepatic lobectomy is still alive eight months after operation. The other three patients with advanced carcinoma at the hilus of the bile duct were treated by intraoperative radiotherapy. A single dose of 3,000 rads was emitted directly to the tumors. The remaining six patients were treated by drainage procedures only. Four patients with advanced carcinoma of the gallbladder had received radiotherapy. Six of the eight patients who were treated by radiotherapy are alive, although the follow-up period extends to 11 months only.

Papilloma of the gallbladder.

A case of papilloma of the gallbladder is reported. The gallbladder was associated with cholesterosis but not with stones. The causes of colicky pain in this case are discussed. Papillomas of the gallbladder exhibit no characteristic clinical picture; the symptoms are similar to those of any type of gallbladder disease. Papillomas of the gallbladder may be associated with malignant degeneration. Cholecystectomy is the treatment of choice.
