The application of mesh-reinforced hiatal closure has resulted in a significant reduction in recurrence rates in comparison with primary suture repair. However, the use of meshes has not completely extended in all the cases of large paraesophageal hiatal hernias (LPHH) due to the complications related to them. The aim of this study is to present our(More)
The most common sex chromosome complex in sex chromatin-positive males with Klinefelter's syndrome is XXY. When the complex is XXYY or XXXY, the clinical findings do not seem to differ materially from those seen in XXY subjects, although more patients with these intersexual chromosome complements need to be studied to establish possible phenotypical(More)
Increased intra-abdominal pressure during laparoscopy changes visceral flow. The objective of the present study was to analyze the changes in peripheral and intra-abdominal flow induced by laparoscopic living-donor nephrectomy in an experimental model. Twenty pigs underwent left-sided nephrectomy, 10 at laparoscopy and 10 in an open approach. Renal blood(More)
To evaluate the effect of two supplementary diets to determine the consequence on productive and reproductive performance in heifers (Bos indicus x Bos taurus) averaging between 24 and 36 months of age and grazing tropical pastures, two trials were conducted. Thirty animals (initial BW 325.1+/-33.6 kg) were divided in two groups in the initial study:(More)
Measurement of interleukins (IL) and C-reactive protein (CRP) have demonstrated that a laparoscopic approach may induce less surgical stress than an open approach. The potential influence of this observation in living donor nephrectomy has scarcely been analyzed. The aim of the study was to analyze the immunohumoral response induced by laparoscopic versus(More)
Bariatric surgery results in the complete resolution of male obesity-associated secondary hypogonadism (MOSH) in many patients. However, the effects of different bariatric surgical procedures on male sexual hormone profiles and sexual dysfunction have not been compared to date. We compared the pre- and post-operative (at least 6 months after initial(More)
The effects of gallamine on the intraspinal field potentials and the dorsal root potentials produced by antidromic stimulation of motor fibres were studied in the isolated frog spinal cord preparation. After gallamine (10-3 M), the duration of the negative field potential produced by antidromic activation of motoneurons (N1 response) was increased often(More)
Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive procedure for diagnosis and treatment of biliary and pancreatic disease that even in expert hands can have complications in 2%–10% of cases, with mortality rates of 0.5%–1% [1,2]. Pancreatitis, cholangitis, perforation, and bleeding from papillotomy have been the most frequently(More)
