Randomized Controlled Trial Comparative Study Clinical Trial[Effects on muscular and general proteolysis in burn patients of a solution enriched with branched amino acids].
In order to assess the effects of a branched chain amino acid (BCAA) enriched solution on urinary nitrogen loss and muscle protein breakdown, 22 burnt patients were randomly divided into two groups immediately after hospital admission: 11 patients received a 22% BCAA amino acid solution, 11 patients received a 41% BCAA amino acid solution. Nitrogen intake was 0.2 g per day during the first 4 days in each group. Urinary total nitrogen, urinary creatinine and urinary 3,methylhistidine (3,MeHis) were measured for 4 days. ⋯ The 3,MeHis/nitrogen ratio on day 1, day 2 and during the whole study period, as well as the 3,MeHis/creatinine ratio on day 2, were significantly lower in the 41% BCAA group. These results were in agreement with a decrease in muscle/whole body urinary nitrogen excretion. However, no beneficial effect upon nitrogen loss or nitrogen balance was shown by using the 41% BCAA rich amino acid solution.

Case Reports[Pneumomediastinum and subcutaneous emphysema after translaryngeal jet ventilation].
The use of emergency transtracheal jet ventilation in a 62 year-old female with laryngeal papillomatosis and respiratory distress is reported. Adequate ventilation of the lungs with an intermittent jet of oxygen under high pressure (5 bar) allowed anaesthesia and surgery to be carried out. Pathogenesis of the mediastinal and subcutaneous emphysema discovered at the end of the procedure is discussed.
