The effects of two solutions of amino acids (AA) were compared in the nutritional assessment of stressed patients requiring total parenteral nutrition (TPN) by finding anthropometric, biochemical and immune parameters on day 0 and day 8. In addition, calculations were made to find the nutritional prognosis index, stress index nitrogenated balance (NB) and net protein use (NPU). A double-blind prospective study was run in which 35 patients with moderate to high stress were divided at random into two groups to receive, for seven days, TPN that was both isonitrogenated (1.56 g/Kg/day of AA) and isocaloric (115.6 +/- 13.6 non-protein Kcal/g. nitrogen), 37% as lipids (LCT), differing only in the AA solution used, one being 15.6% and the other, 45% BCAA. Twenty-eight patients finished the study, 14 in each group. No significant differences were found between the groups in the parameters under study; however, the patients who received the 45% BCAA solution obtained superior development of the parameters evaluating nutritional status and an increase in their NB (p = 0.0213) and NPU (p = 0.0497). Total lymphocytes increased significantly in both groups. Disturbances in hepatic enzymes and alkaline phosphatase (AF) were higher than in the standard group. Gamma glutamyl transferase (GGT) increased in group I (p = 0.0168), while in group II there were increases of GGT (p < or = 0.05), glutamic pyruvic transaminase (GPT) (p < or = 0.025) and AF (p = 0.0213). In the standard group, plasma urea increased (p = 0.0117), and the creatine/size ratio decreased (p = 0.0094). Anthropometric measurements were not valid in this study. The results do not allow the conclusion to be drawn that the 45% BCAA solution is the most effective, but it does make clear that its use is suitable in patients with moderate and high levels of stress, changing to standard AA solutions when the patients improve.
Four cases of Aicardi's syndrome are presented, reporting in two of them angiographic and bone abnormalities such as arterial microaneurysm and scapula displacement, that have not been previously reported in the literature.
INTRODUCTION: The laryngostroboscopy allows analysis of the vocal fold vibrations during phonation. Disruption of normal viscoelastic properties of the superficial lamina propria results in aberrant vocal fold vibration and mucosal wave propagation. Therefore, an investigation was performed to relate the stroboscopic results with the anatomopathologic results of chronic laryngitis and glottic cancer. MATERIAL AND METHODS: We performed a retrospective study, which included 30 direct laryngoscopies with biopsy of 25 patients and their corresponding laryngostroboscopies. RESULTS: 60% of the cases of "absence of mucosal wave" displayed severe dysplasia or carcinoma. 20% of the cases of "limited or present mucosal wave" were carcinoma. CONCLUSIONS: The probability of finding severe dysplasia or carcinoma is significantly greater when we find absence of mucosal wave. The presence of mucosal wave does not exclude the possibility of malignant lesion of the vocal fold.
