A 47-year-old male with histiocytic lymphoma and no previous history of heart disease developed significant fluctuations of blood pressure, electrocardiographic evidence of myocardial ischemia, and life-threatening arrhythmia after the first dose of BACOP (bleomycin, adriamycin, cyclophosphamide, Oncovin, and prednisone) chemotherapy. The presence of pheochromocytoma was suspected, and it was demonstrated by elevated urinary metanephrines, catecholamines, and vanillylmandelic acid, and finally confirmed on autopsy. The possible role of chemotherapeutic agents in stimulating excessive catecholamine release, thus causing transient cardiac injury, is suggested.

The mortality experience of alcohol process workers (N = 1031) from two chemical plants was followed from the early 1940s to 1983. Reported associations of the production of ethanol and isopropanol by the strong-acid process with upper respiratory tract cancers, heart disease, and lympho- and reticulosarcoma were tested with both external and internal comparisons. Excesses of cancers of the larynx, buccal cavity, and pharynx, based on very small numbers, were observed. There was one death due to sinus cancer. It could not be concluded that there were work-related effects on mortality due to heart disease or lympho- or reticulosarcoma. Workers assigned to the production of isopropanol by the weak-acid method showed no evidence of excess cancer mortality (0 observed, 1.9 expected cancer deaths). The absence of major risks among strong-acid workers can be explained by the initiation of engineering controls and health monitoring that took place after the original medical observations.

Williams-Beuren syndrome (WBS) is a genetic disorder characterized by a distinctive facial gestalt, mental retardation, mild growth deficiency, and cardiovascular disease. The occurrence of sudden death in the WBS is known from several case reports, but information about the risk of sudden death as derived from the data of a large cohort of patients is lacking. We analyzed the data of 293 WBS patients who had been treated for 43 years at the same two institutions. We thus collected 5,190 patient years without loss to follow-up. During this period ten patients died. Five of them died from: reticulosarcoma (1), after accident (1), heart failure (1), following heart surgery (2). Of the remaining five patients, four died suddenly and one died of unknown cause suggestive of sudden cardiac death. Thus, the incidence of sudden death in our WBS cohort amounts to 1/1,000 patient years. This risk of sudden death is comparable to that following surgery for congenital heart disease, and is 25-100-fold higher compared to the age-matched normal population.
