Peritumoral stroma and systemic inflammatory response in cervical cancer.

Objective: To compare cervical stroma in advanced cervical cancer with the control group; to compare, in the pre-treatment period, hemogram parameters in patients with advanced cervical cancer with the same parameters as the control group; and to verify if there is an association of stromal markers with prognostic factors in cervical cancer.

Materials And Methods: We prospectively evaluated 16 patients diagnosed with advanced invasive cervical cancer. A control group of 22 patients was used (uterine leiomyoma).

Analysis of CD15, CD57 and HIF-1α in biopsies of patients with peri-implantitis.

Peri-implantitis is an infectious disease characterized by inflammation of the tissues surrounding the implant, bleeding on probing with or without suppuration, and bone loss. Peri-implant lesions contain a leukocyte infiltrate of plasma cells, lymphocytes, macrophages and neutrophils. A survey of the literature did not show any studies reporting an association between hypoxia and peri-implantitis.

Clinical and epidemiological prevalence of glomerulopathies elderly in the city of Uberaba - MG.

Introduction: Currently, the elderly population of Brazil is suffering significant increase. Aging is a physiological process that causes changes in various organs, including the kidney. A kidney biopsy is of paramount importance to clarify the morphological changes of these entities.

Immunohistochemical staining of tumor necrosis factor-α and interleukin-10 in benign and malignant ovarian neoplasms.

Ovarian cancer is the ninth most common malignancy and the fifth leading cause of cancer death in women in the USA. The majority of malignant tumors of the ovary are diagnosed at an advanced stage, making it the most fatal gynecological cancer. The aim of the current study was to determine whether there are differences in immunohistochemical tissue staining of cytokine tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) between benign tumors and malignant primary ovarian cancer.

Renal biopsy: use of biomarkers as a tool for the diagnosis of focal segmental glomerulosclerosis.

Focal segmental glomerulosclerosis (FSGS) is a glomerulopathy associated with nephrotic syndrome and podocyte injury. FSGS occurs both in children and adults and it is considered the main idiopathic nephrotic syndrome nowadays. It is extremely difficult to establish a morphological diagnosis, since some biopsies lack a considerable quantifiable number of sclerotic glomeruli, given their focal aspect and the fact that FSGS occurs in less than half of the glomeruli.

A retrospective study on cervical intraepithelial lesions of low-grade and undetermined significance: evolution, associated factors and cytohistological correlation.

Context And Objectives: Cervical cancer is an important cause of morbidity and mortality throughout the world. There is some controversy about the factors that may be associated with infection by the human papillomavirus (HPV) that may favor or protect against evolution from a low-grade intraepithelial lesion to a high-grade intraepithelial lesion or invasive neoplasia. The objective here was to evaluate the evolution of low-grade intraepithelial lesions and squamous or glandular lesions of undetermined significance, the associated factors and cytohistological correlations.

Correlation of cytokines and inducible nitric oxide synthase expression with prognostic factors in ovarian cancer.

The study related the immunohistochemical staining of cytokines (IL2, IL5, IL6, IL8, IL10, and TNF-alpha), and iNOS staining with clinical and pathological parameters of patients with primary ovarian malignancy. We prospectively evaluated 40 patients who underwent surgical treatment in accordance with pre-established criteria and later confirmed diagnosis of ovarian cancer. Immunohistochemistry study for cytokines (IL2, IL5, IL6, IL8, IL10, TNF-alpha) and iNOS was performed.

An overview of molecular mechanism of nephrotic syndrome.

Podocytopathies (minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS)) together with membranous nephropathy are the main causes of nephrotic syndrome. Some changes on the expression of nephrin, podocin, TGF-β, and slit diaphragm components as well as transcription factors and transmembrane proteins have been demonstrated in podocytopathies. Considering the pathogenesis of proteinuria, some elucidations have been directed towards the involvement of epithelial-mesenchymal transition.

Research on Trypanosoma cruzi and Analysis of Inflammatory Infiltrate in Esophagus and Colon from Chronic Chagasic Patients with and without Mega.

To compare parasitism and inflammatory process in esophagus and colon from chronic chagasic patients, immunohistochemistry was carried out to research for T. cruzi and to evaluate the inflammatory infiltrate in the muscular and myenteric plexus in 39 esophagi (20 with and 19 without megaesophagus) and 50 colons (25 with and 25 without megacolon). The frequency of T.
