Experimental stress and cystomanometric recordings of patients with primary enuresis, a preliminary report.

The motility of the bladder has been recorded for 20 children with nocturnal enuresis while they were submitted to emotional tenseness experimentally induced. The analysis showed that emotional stress leads to contractions of the detrusor only in patients with psychogenic enuresis and not in those for whom organic lesions were responsible for the disturbance and that the motor response depends on the level of emotional tenseness. Such results are of interest for diagnosis and physiopathology of psychogenic enuresis.

Pathogenesis of hepatic encephalopathy and hyperdynamic syndrome in cirrhosis. Role of false neurotransmitters.

We sought to determine whether false neurotransmitters (FNTs) play an important role as determinants not only of hepatic encephalopathy but also of hyperdynamic syndrome in cirrhosis. A combined biochemical and hemodynamics study of 55 bleeding cirrhotic patients was made. We evaluated the aromatic and aliphatic branched-chain amino acids and octopamine serum levels as well as the hemodynamic measurements. The results show that there is a correlation between levels of serum octopamine and aromatic amino acids and hepatic coma: the higher the octopamine level, the deeper the hepatic coma. There is also a correlation between aromatic amino acids and cardiac index and total peripheral resistance. Furthermore, when a narrowing of arteriovenous difference in oxygen occurs and oxygen consumption decreases, there is an increase not only in the level of aromatic amino acids, but also in octopamine level, suggesting an important linkage between hemodynamic and metabolic impairment.

Woolly hair and palmoplantar hyperkeratosis may present with hypertrophic cardiomyopathy.

Woolly hair and palmoplantar hyperkeratosis is an infrequent autosomal recessive ectodermal disorder that may be associated with arrhythmogenic right ventricular dysplasia (Naxos disease) or dilated cardiomyopathy. We report the sporadic occurrence of the aforementioned skin-hair anomalies in a patient with physical findings compatible with Noonan's syndrome and hypertrophic cardiomyopathy-an association heretofore not described.

Perioperative total parenteral nutrition in malnourished, gastrointestinal cancer patients: a randomized, clinical trial.

BACKGROUND: Clinical trials investigating the potential benefits of perioperative total parenteral nutrition (TPN) for reducing the risk of surgery in malnourished cancer patients have yielded controversial results. METHODS: Ninety elective surgical patients with gastric or colorectal tumors and weight loss of 10% or more of usual body weight were randomly assigned to 10 days of preoperative and 9 days of postoperative nutrition vs a simple control group. The daily per kilogram body weight TPN regimen included 34.6 +/- 6.3 kcal nonprotein and 0.25 +/- 0.04 g nitrogen per kilogram in a volume of 42.6 +/- 7.3 mL of fluid. The glucose-to-fat calorie ratio was 70:30. Control patients did not receive preoperative nutrition but received 940 kcal nonprotein plus 85 g amino acids postoperatively. RESULTS: Complications occurred in 37% of the patients receiving TPN vs 57% of the control patients (p = .03). Noninfectious complications mainly accounted for this difference, which was 12% vs 34%, respectively (p = .02). Mortality occurred in only 5 of the control group patients (p = .05). The total length of hospitalization for TPN patients was longer than for control (p = .00), whereas the length of postoperative stay in the two groups did not differ significantly. CONCLUSIONS: This study shows that 10 days of preoperative TPN that is continued postoperatively is able to reduce the complication rate by approximately one third and to prevent mortality in severely malnourished patients with gastrointestinal cancer.

Treatment of cancer of the base of the tongue and glosso-epiglottic region: a multicenter Italian survey. GLOCC Group. Gruppo di Lavoro in Oncologia Cervico Cefalica.

BACKGROUND: The current treatment options for cancer of the base of the tongue and glosso-epiglottic region are surgery, radiotherapy, or a combination of both modalities. Comparisons between different modalities are not common in the literature, and a real standard of treatment has not yet been established. The purpose of our study was to evaluate the results of treatment in a large series of patients from 18 Italian institutions in relation to the main treatment adopted. METHODS: The present study is a retrospective survey. The series was divided into a combined surgery group and a radiotherapy group. The Kaplan-Meier method and the log-rank test were used for survival calculations and comparisons. RESULTS: Eight hundred patients were registered (25.7% stage III and 62% stage IV), 336 in the surgery and 372 in the radiotherapy group. Conventional fractionation was adopted in almost all cases. The five-year overall and disease free survival of the whole series was 32% and 38%, respectively. Survival was slightly better for patients with tumors of the glosso-epiglottic region than for those with a tumor of the base of the tongue. Five-year disease-free survival was 55% for patients treated with surgery +/- radiochemotherapy and 26% for those submitted to radiotherapy alone or in combination with chemotherapy. As far as the total dose and the treatment duration were concerned, only 26% of the patients of the radiotherapy group met the established criteria of adequacy, but in patients with adequate radiation the control rate was better only for small tumors (T1-T2). CONCLUSIONS: The results in patients treated with surgery +/- postoperative radiotherapy were similar to or better than those reported in the best series in the literature. By contrast, the survival rate of irradiated patients was lower than those reported by other centers.
