Marked seasonality of Cyclospora cayetanensis infections: ten-year observation of hospital cases, Honduras.

Background: Document seasonality occurrence and epidemiologic characteristics of Cyclospora cayetanensis infections during a 10-year period from patients consulting at the University Hospital, Honduras.

Methods: Retrospective non interventional hospital-based study analyzed laboratory results from the period 2002 to 2011 of fresh and Ziehl-Nielsen carbolfuchsin stained routine stool samples received for parasitologic examination. Sporadically a sample with numerous oocysts was allowed to sporulate in 2.

The FAT expandability (FATe) Project: Biomarkers to determine the limit of expansion and the complications of obesity.

Background: Obesity is an excessive accumulation of fat frequently, but not always, associated with health problems, mainly type 2 diabetes and cardiovascular disease. During a positive energy balance, as caused by excessive intake or sedentary lifestyle, subcutaneous adipose tissue expands and accumulates lipids as triglycerides. However, the amount of adipose tissue per se is unlikely to be the factor linking obesity and metabolic complications.

Laparoscopic biliopancreatic diversion with distal gastric preservation: technique and three-year followup.

Background: Biliopancreatic diversion (BPD) has been used satisfactorily as one of several surgical treatments against morbid obesity in order to achieve long-term weight reduction. Our goal was to develop the BPD laparoscopically in humans in order to improve postoperative recovery and to reduce early and late complications, above all those derived from the abdominal wall, while maintaining the weight reduction results achieved. In addition, in order to reduce the laparoscopic difficulty of BPD technique and some complications associated with gastrectomy, we only carried it out in cases in which we considered it indispensable.

Laparoscopic biliopancreatic diversion: technical aspects and results of our protocol.

Background: Biliopancreatic diversion (BPD) has been an excellent operation for morbid obesity to achieve long-term weight reduction. We present our laparoscopic BPD protocol, which includes laparoscopic BPD with or without gastrectomy.

Methods: Our two interventions are: 1) BPD (Scopinaro) by laparoscopy in patients with findings on gastroscopy; 2) BPD by laparoscopy with proximal gastric division without resection in patients without findings on gastroscopy.

Retroperitoneal mucinous cystadenoma.

Introduction: Retroperitoneal mucinous cystadenomas are rare tumors. Only 25 cases have been reported in the English literature until 2002. The histogenesis is unclear, diagnosis is never made preoperatively and surgery is the only treatment.
