[Alcoholic hepatopathy, deficiency pathology and serum transaminases. Presentation of 2 clinical cases].

The authors describe two cases of Vit B1 and B6 deficiency in alcoholics with malnutrition. In the first case serum levels of AST and ALT, initially below norm became higher after Vit B1 and Vit B6 intake; the second, with AST and ALT above norm in previous months, had AST and ALT with normal activity during the disease. The authors suggest that normal activity of AST and ALT during alcoholic hepatopathy could be related to a depletion of Vit B1 and Vit B6.

Lung function in essential mixed cryoglobulinemia: a short-term follow-up.

Lung involvement in essential mixed cryoglobulinemia (EMC) has been recently described. In order to assess whether patients with EMC experience an accelerated deterioration of lung function, nineteen patients (17 females, 2 males; 49.6 +/- 6.

Variability of maximal expiratory flow-volume curve in young volley players.

In order to assess the variability of forced expiratory flows, 15 male players (age 16-19 years, height 182-201 cm) of the Italian National Junior Volley team were studied twice with the pneumotachygraph of the computerized Hewlett-Packard Pulmonary System. The first time (April), but not the second (July), all the subjects were physically trained. Each subject performed at least three acceptable forced vital capacity (FVC) maneuvers, following the standard of the American Thoracic Society, with the exception of the criterion for determining the FVC end point.
