A transitory serum elevation of hepatocellular enzyme alanine-aminotransferase (ALT) and gamma GT is reported during i.v. treatment with nitroderivatives of acute myocardial infarction. authors have reviewed 144 case (105 males and 39 females) admitted to the emergency ward for acute myocardial infarction: of the 144 cases reviewed, 54 males and 16 females (48.6% of the total) presented a significative increase of ALT and gamma GT, up to the maximum value of 220 U/l, during the first week of continuous i.v. therapy with nitroderivatives. This elevation was transient, with return to normal values during the first month. The AA postulate that this increase is dose-dependent, linked to individual susceptibility and possibly due to the production of free oxygen radicals.

In this retrospective study, we evaluated two different modes of weaning: assisted spontaneous breathing (ASB) plus CPAP with automatic tube compensation (Evita 4, Draeger Medical, Germany) versus assisted spontaneous ventilation (ASV) (Galileo Gold, Hamilton Medical, Switzerland) in 80 patients who had undergone abdominal surgery. Our target was to assess differences in weaning times using different modes of assistance.

The AA. report a case of thymine acute deficiency in a 35 year old chronic alcoholic and malnourished male, who was admitted to the hospital because of high-output heart failure, peripheral polyneuropathy, cortico-cerebellar atrophy (associated with RMN), ataxia and peripheral edema. The diagnosis of wet Beri-beri combined with Wernicke-Korsakoff syndrome was made and appropriate therapy with pulse daily dose of parenteral thymine instituted. At the fifth day of therapy the cardio-circulatory hyperkinetic syndrome was markedly improved and after three weeks neurological damage was also alleviated. The AA. outline the importance of early diagnosis and treatment for this form of high-output heart failure, which has a poor prognosis and, if left untreated, can determine the death of the patient in a few days.

A retrospective survey is made on 166 cases of acute myocardial infarction, treated with intravenous nitro-derivatives for eight days of continuous therapy. This therapeutic modality appears to gain four goals: a reduction in mortality of patients, a faster return of ST tract on isoelectric guideline, fewer ventricular pump failures. In the authors' point of view, a delay in the downward return of ST tract towards the isoelectric guideline is an important but ominous prognostic sign in this group of patients. Therefore, this modality of treatment is suggested for all patients with AMI, wherever the myocardial coronary lesion is localized.
