[Myocardial involvement in rhabdomyolysis caused by acute heroin intoxication].

It is well known that heroin overdose may cause rhabdomyolysis. Sometimes a myocardial involvement complicates its course. We report a case of heroin intoxication followed by rhabdomyolysis associated with myocardial injury, with symptoms, laboratory findings, ECG and echocardiography features of non-Q wave infarction. However, a 201 Tl myocardial scintigraphy, performed after patient discharging, did not show any abnormality. We think that heroin has a direct myotoxic effect on both myocardium and skeletal muscle. Yet we cannot exclude that hypoxia, acidosis, vasoconstrictive substances released by muscle necrosis, or hypersensitivity reactions associated with heroin or some of its adulterants are involved in myocardial injury.

[Toxic occupational liver diseases. Therapeutic effects of silymarin].

We considered two groups, one of 35 and the other of 20 patients, with occupational toxic hepatopathy caused by various toxic substances (mostly solvents, paints and glues). The patients were mostly suffering from chronic or subacute forms. We considered the work conditions in the anamnesis, the period of exposure and most important laboratory parameters of hepatic function checked before and after treatment with Silymarin (420 mg/die/os) for the first group and with "placebo" for the second group. Five patients of the first group were diagnosed by biopsy. The treatment with Silymarin has shown slight variations in some parameters. The therapeutic effect is probably not dependent upon the kind of pathogen noxa; it seems instead to be more evident when the exposure period is shorter. The group "placebo" does not show significant variations.
