1. A Three Point Assessment Protocol for Tympanoplasty Outcomes: A Retrospective Analysis
Abstract Introduction The surgical outcome of chronic otitis media (COM) of the mucosal type in the pediatric population with high rates of recurrent tympanic membrane perforation is indeed a concern for the attending surgeon. Objective The present study was done to evaluate the outcome of tympanoplasty in children with chronic otitis media mucosal type.

2. Renal transplant patients with preformed anti-HLA antibodies: early biopsy findings and clinical outcomes
Resumo Introdução: A fibrose renal é o desfecho de um processo iniciado no transplante, com reperfusão, isquemia e inflamação precoce, que progride ao longo do tempo com fenômenos imunológicos e não imunológicos. A identificação de marcadores morfológicos e a intervenção precoce poderiam melhorar a função e a sobrevida do enxerto. Objetivo

3. HLA alleles in renal transplant recipients with nonmelanoma skin cancer in southeastern Brazil
Abstract: Background: Renal transplant recipients are submitted to immunosuppression to avoid graft rejection, which makes them susceptible to various conditions. Furthermore, these individuals present malignant tumors more frequently than the general population, including nonmelanoma skin cancer. The individual genetic basis that acts in the pathogenesis o

4. Non-invasive messenger RNA transcriptional evaluation in human kidney allograft dysfunction
The aim of the present study was to evaluate messenger RNA expression in kidney allograft recipients. Forty-four kidney transplant recipients were evaluated up to three months after grafting. After transplantation, peripheral blood samples were drawn sequentially for real-time polymerase chain reaction analyses of perforin and TIM-3 genes. Biopsies were obta

5. Skin disorders in renal transplant recipients: a retrospective study
Abstract: Background: Immunosuppressive therapy, which is necessary to avoid graft rejection in renal transplant recipients, presents an increased risk of several pathologies, namely infectious and neoplastic. Objectives: To identify the most frequent skin diseases and their clinical and demographical risk factors within a population of renal transplant re

6. Upregulation of microRNA 142-3p in the peripheral blood and urinary cells of kidney transplant recipients with post-transplant graft dysfunction
We analyzed microRNA (miR)-142-3p expression in leucocytes of the peripheral blood and urinary sediment cell samples obtained from kidney transplant recipients who developed graft dysfunction. Forty-one kidney transplant recipients with kidney graft dysfunction and 8 stable patients were included in the study. The groups were divided according to histologica

7. Human islet xenotransplantation in rodents: A literature review of experimental model trends
Among the innovations for the treatment of type 1 diabetes, islet transplantation is a less invasive method of treatment, although it is still in development. One of the greatest barriers to this technique is the low number of pancreas donors and the low number of pancreases that are available for transplantation. Rodent models have been chosen in most studi

8. Remote ischemic preconditioning and tacrolimus in the fetal small bowel transplant in mice
ABSTRACT PURPOSE: To evaluate the effect of remote ischemic preconditioning (IPC-R) in the fetal small bowel transplantation model. METHODS: Two groups were constituted: The Isogenic transplant (ISO, C57BL/6 mice, n=24) and the allogenic transplant (ALO, BALB/c mice, n=24). In each group, the animals were distributed with and without IPC-R. It was obtained

9. Prognostic factors for the evolution and reversibility of chronic rejection in pediatric liver transplantation
OBJECTIVE: Chronic rejection remains a major cause of graft failure with indication for re-transplantation. The incidence of chronic rejection remains high in the pediatric population. Although several risk factors have been implicated in adults, the prognostic factors for the evolution and reversibility of chronic rejection in pediatric liver transplantati

10. Use of preoperative embolization prior to Transplant nephrectomy
ABSTRACT Introduction After a failed transplant, management of a non-functional graft with pain or recurrent infections can be challenging. Transplant nephrectomy (TN) can be a morbid procedure with the potential for significant blood loss. Embolization of the renal artery alone has been proposed as a method of reducing complications from an in vivo failed

11. CTLA4 enhances the osteogenic differentiation of allogeneic human mesenchymal stem cells in a model of immune activation
Allogeneic mesenchymal stem cells (allo-MSCs) have recently garnered increasing interest for their broad clinical therapy applications. Despite this, many studies have shown that allo-MSCs are associated with a high rate of graft rejection unless immunosuppressive therapy is administered to control allo-immune responses. Cytotoxic T-lymphocyte-associated pro

12. Quantification of C4d deposition and hepatitis C virus RNA in tissue in cases of graft rejection and hepatitis C recurrence after liver transplantation
Histology is the gold standard for diagnosing acute rejection and hepatitis C recurrence after liver transplantation. However, differential diagnosis between the two can be difficult. We evaluated the role of C4d staining and quantification of hepatitis C virus (HCV) RNA levels in liver tissue. This was a retrospective study of 98 liver biopsy samples divide
