Pancreas Transplantation at a Single Latin-American Center; Overall Results with Type 1 and Type 2 Diabetes Mellitus.

Background: Simultaneous pancreas-kidney transplantation (SPK) has become the treatment of choice for type 1 diabetes mellitus (T1DM) patients with chronic renal failure. Type 2 diabetes mellitus (T2DM), was once considered to be a contraindication for pancreas transplantation; however, it has been accepted as a new indication, under strict criteria. Although favorable results have increase the indication for T2DM in developed countries, there have been no reports of long-term results for this indication from Latin American centers.

Cumulative incidence, indications, morbidity and mortality of transplant nephrectomy and the most appropriate time for graft removal: only nonfunctioning transplants that cause intractable complications should be excised.

Purpose: We assessed the cumulative incidence of transplant nephrectomy in our population of patients who underwent transplantation and those in whom the transplant failed due to immunological causes. Transplant nephrectomy indications, morbidity and mortality were analyzed to establish the most appropriate time for graft removal.

Materials And Methods: We included all patients who underwent transplantation and graft removal at our institution from January 1, 1970 through January 1, 2000.

Comparing Taguchi and Lich-Gregoir ureterovesical reimplantation techniques for kidney transplants.

Purpose: We compared the incidence of urological and anastomotic complications, and the duration of ureteral reimplantation for the Taguchi and Lich-Gregoir techniques.

Materials And Methods: We recorded all urological and anastomotic complications that developed from the date of transplantation through December 31, 2001. The cutoff date for transplantation was August 30, 2000.

[Value of gray scale ultrasonography in the early diagnosis of urologic complications of renal transplantation].

Objective: To determine the significance of gray scale ultrasound as a tool for diagnosis, follow-up and treatment of urological complications of renal transplantation based on the experience of our institution.

Methods: A retrospective, longitudinal and observational study was carried out. We reviewed the patients' perioperative ultrasound scans and their respective urological complications from January 1, 1982 to January 1, 2000.

Enhanced expression of alpha(1,3)-fucosyltransferase genes correlates with E-selectin-mediated adhesion and metastatic potential of human lung adenocarcinoma cells.

Alpha(1,3)- and alpha(1,4)-fucosylated oligosaccharides such as sialyl-Lewis(x) (sialyl-Le(x)) and sialyl-Lewis(a) (sialyl-Le(a)) have been reported to participate in tumor cell adhesion to activated endothelium. We examined by cytofluorometry the expression of Le(x), sialyl-Le(x), sialyl-Le(x) dimeric, Le(a), and sialyl-Le(a) on the surface of two human lung adenocarcinoma cell lines with different lung colonization potential. High expression levels of all of these antigens were detected in the metastatic HAL-8Luc cells, whereas the closely related nonmetastatic HAL-24Luc cells only expressed the sialyl-Le(a) and sialyl-Le(x) dimeric antigens, both at lower level than in HAL-8Luc cells.
