Pancreata from pediatric donors restore insulin independence in adult insulin-dependent diabetes mellitus recipients.

CONTEXT: The use of pediatric donors can increase the number of donors available for pancreas transplantation. AIM: The aim of this study was to verify if pancreas transplantation from pediatric donors is as effective as transplantation from adult donors to restore metabolic control in type 1 diabetic patients. MATERIALS AND METHODS: From 2000 to April 2009 we performed 17 pancreas transplantations from pediatric donors: 9 simultaneous kidney-pancreas (SPK), 6 pancreas transplantation alone (PTA), and 2 pancreas after kidney (PAK). All subjects received whole organs with enteric diversion of exocrine secretions; 11 underwent systemic and 6 underwent portal venous graft drainage. The immunosuppressive therapy was as follows: prednisone, mycophenolate mofetil, anti-thymocyte globulin (ATG), and cyclosporine or tacrolimus. The pediatric donor population had a mean age of 15.3 years (range, 12-17), a mean weight of 60.1 kg (range, 42-75), and a mean body mass index (BMI) of 21 (range, 17.9-23.4). RESULTS: After 9 years the overall patient survival rate was 94.12%, whereas the graft survival rate was 63.35%. Normal glucose and insulin levels were maintained either fasting or during oral glucose tolerance test (OGTT). The group of recipients of pediatric organs was compared with patients receiving organs from adult donors (n = 125); the mean glucose values were lower in the pediatric group, whereas insulin production was higher in the adult patients. Early venous thrombosis was 17.6% in the pediatric group and 20% in adult recipients (Fisher exact test, P = not significant [NS]). CONCLUSION: Pediatric donors restored insulin independence in adult diabetic recipients, representing a valid source of organs for pancreas transplantation.

[Therapeutic effects of trazodone in the treatment of tremor. Multicentric double-blind study]. / Effetti terapeutici del Trazodone nel trattamento del tremore. Studio policentrico in doppio cieco.

A 30 days therapeutical trial with trazodone has been performed in 47 patients suffering from different types of tremor. No significant improvement was detected in patients suffering from parkinsonian syndromes, multiple sclerosis, psycogenic tremor and hyperthyroidism. After the double-blind trial with trazodone, a significant improvement (p less than 0.025) was, instead, evident in 5 out of 6 patients with essential tremor, while the score did not change in the 3 patients with essential tremor who were treated with placebo.
