Circadian rhythmicity is affected in obese subjects. This article analyzes the effect of a high-fat diet (35% fat) on 24-h changes circulating prolactin, luteinizing hormone (LH), testosterone, corticosterone, thyroid-stimulating hormone (TSH) and glucose, and pineal melatonin content, in rats. When body weight of rats reached the values of morbid obesity,(More)
A prospective study of serum cytokine levels was performed in patients randomly assigned to undergo either laparoscopic cholecystectomy (LC) or open cholecystectomy (OC). The kinetics of serum interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10), and cortisol were studied in both groups of(More)
HYPOTHESIS Complications associated with thyroidectomy for intrathoracic goiters have been underestimated because of the lack of a precise definition of high-risk patients. DESIGN Retrospective multicenter multinational review of medical records and radiographic images of patients who underwent thyroidectomy for intrathoracic goiters reaching the carina(More)
BACKGROUND There is clinical evidence that the surgical insult experienced by patients who undergo laparoscopic cholecystectomy (LC) differs significantly from that experienced by those undergoing open cholecystectomy (OC). LC is accompanied by less pain, better ventilatory function and almost total absence of secondary paralytic ileus. The aim of the(More)
A hemangiopericytoma in a male breast was studied by fine needle aspiration (FNA) biopsy. The FNA smears contained tissue clumps showing knob-like formations of atypical cells, spindle-shaped cells and fragments of capillaries lined by normal endothelial cells. Immunocytochemical study showed a positive reaction for vimentin, but a negative reaction for(More)
An interdisciplinary panel of specialists met in Mallorca in the first European Symposium on Morbid Obesity entitled; "Morbid Obesity, an Interdisciplinary Approach". During the two and half days of the meeting, the participants discussed several aspects related to pathogenesis, evaluation, and treatment of morbid obesity. The expert panel included basic(More)
OBJECTIVE To assess the immediate and long-term clinical results of 2 different surgical procedures for the treatment of asymmetrical multinodular goiter (AMG). BACKGROUND Half of the patients presenting with a single benign thyroid nodule have contralateral subclinical disease. There is a controversy whether these patients should be treated with(More)
Somatostatin and octreotide both enhance closure of gastrointestinal fistulas. The present trial was undertaken to test whether early combined treatment with parenteral nutrition and octreotide 100 micrograms every 8 h by subcutaneous injection had a beneficial effect compared with parenteral nutrition plus placebo. Thirty-one patients with post-operative(More)
The present work analyses the possible influence of the colon in weight gain of obese animals. Subtotal colectomy was performed in rats fed with standard chow or high-fat diets. The results, suggested that subtotal colectomy did not exert any effect on the % of weight gain in rats administered a high-fat diet during the whole experiment as compared to(More)
