Abstract: Ninety-six patients with disseminated malignant melanoma received thrice weekly intramuscular injections of leukocyte A recombinant interferon (rIFN-alpha A, Roferon-A, Hoffmann La Roche) at doses of 12 X 10(6) U/m2 or 50 X 10(6) U/m2 with or without cimetidine as an immunorestorative agent. Four patients, two with prior chemotherapy, demonstrated either a complete response (3 months, soft tissue metastasis) or exceptionally durable response durations (months) of 29+ (soft tissue; lung lesion), 31+ (soft tissue), and 35+ (soft tissue; liver lesions). None of these patients had particularly characteristic clinical parameters. As noted previously, using chemotherapy, a small proportion of patients with advanced malignant melanoma, despite prior therapy, may achieve prolonged objective regression with rIFN-alpha A.

Abstract: A man with no previous medical problems had two documented exposures to an insecticide containing the organophosphorous compounds chlordane and heptachlor. Six months to one year later, he began to experience neurological symptoms which progressed until his death. At autopsy, his brain showed classic findings of multiple sclerosis, and he had a severe peripheral neuropathy. Review of the literature indicates that the findings are not compatible with chlordane toxicity. Some of the factors to be used in determining the casual relationship between toxic exposure and disease processes are discussed.

Abstract: Today, echocardiography enjoys a prominent place in the physician's diagnostic armamentarium. Its safe application, accuracy, and reproducibility have made its widespread use popular. The ability of echocardiography to visualize cardiac valves, intracardiac masses, and ventricular wall motion is unique. This article highlights the applications of echocardiography from the physician's vantage point.
