Brazilian consortium for the study on renal diseases associated with COVID-19 :...

Kidney involvement appears to be frequent in coronavirus disease 2019 (COVID-19). Despite this, information concerning renal involvement in COVID-19 is still scarce. Several mechanisms appear to be involved in the complex relationship between the virus and the kidney. Also, different morphological patterns have been described in the kidneys of patients with COVID-19. For some authors, however, this association ...

The Oxford Classification predictors of chronic kidney disease in pediatric pat...

Objective: The Oxford Classification for Immunoglobulin A nephropathy (IgAN) identifies pathological variables that may predict the decline of renal function. This study aimed to evaluate the Oxford Classification variables as predictors of renal dysfunction in a cohort of Brazilian children and adolescents with IgAN. Methods: A total of 54 patients with IgAN biopsied from 1982 to 2010 were assessed. Biopsies w...

The role of immunohistochemistry in the detection of vascular invasion in speci...

Introduction: Endoscopic submucosal dissection (ESD) of early neoplasias of the gastrointestinal tract (GIT) has been increasingly applied as an alternative to invasive surgical procedures, with the aim to preserve the patient’s organ and quality of life, although it does not allow the histopathological analysis of lymph nodes. Previous studies demonstrated that the presence of neoplastic emboli in lymphatic (l...

Hanseníase multibacilar em paciente transplantado renal : relato de caso.

O Brasil é um país onde a hanseníase ainda é um problema de saúde pública, apresentando mais de 30.000 novos casos por ano nos últimos anos. Apesar do crescente número de transplante de órgãos sólidos realizados no país, sobretudo o transplante renal, não são frequentes os relatos dessa micobacteriose em pacientes imunossuprimidos pelas medicações pós-transplante. Os autores relatam um caso de hanseníase multib...

Polyomavirus infection in renal allograft.

Combined use of Paracoccidioides brasiliensis recombinant rPb27 and rPb40 antig...

Paracoccidioidomycosis (PCM) is one of themost important endemicmycoses in LatinAmerica; it's usually diagnosed by observation and/or isolation of the etiologic agent, Paracoccidioides brasiliensis, as well as by a variety of immunological methods, such as complement fixation and immunodiffusion. Although these approaches are useful, historically their sensitivity and specificity have often been compromised by ...

Paracoccidioidomycosis case series with and without central nervous system invo...

Introduction: Paracoccidioidomycosis (PCM) is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC) and compare their characteristics with patients without neurological involvement, to identify unique characteristics...
