A paraplegic patient, who had worn a rubber urinal in close contact with the scrotum for over 40 years, developed carcinoma of the scrotum. It is likely that this is a previously unsuspected example of chemical carcinogenesis, and in view of this, we believe that the use of rubber urinals should be discontinued.

We undertook a prospective study of the effect of incidental appendectomy on the safety of cholecystectomy in patients under the age of 50 years. One hundred twenty patients were randomized to have either cholecystectomy alone or cholecystectomy and appendectomy. All patients received preoperative antibiotic cover. Both groups were well matched for age, sex, obesity, and length of hospital stay. Twelve patients were withdrawn from the trial. Wound infections occurred in three of the 56 patients in the cholecystectomy group (5.3%) and in two of the 52 patients in the cholecystectomy plus appendectomy group (3.8%). Incidental appendectomy is a safe addition to elective cholecystectomy.

A case of idiopathic spontaneous aortoduodenal fistula treated surgically is reported. This case is probably the first successful repair of an idiopathic fistula to be recorded in the literature. The difficulty in diagnosis and possible aetiology are discussed.
