OBJECTIVE: To correlate the Thyroid Imaging Reporting and Data System (TI-RADS) and the Bethesda system in reporting cytopathology in 1,000 thyroid nodules. METHODS: A retrospective study conducted from November 2011 to February 2014 that evaluated 1,000 thyroid nodules of 906 patients who underwent ultrasound exam and fine needle aspiration. RESULTS: A significant association was found between the TI-RADS outcome and Bethesda classification (p<0...

BACKGROUND: Thyroid hormone deficiency during fetal life could affect the cardiac function in later life. The mechanism underlying this action in fetal hypothyroidism (FH) in rats has not been elucidated thus far. OBJECTIVE: The aim of this study is to evaluation the effect of FH on cardiac function in male rats and to determine the contribution of α-myosin heavy chain (MHC) and β-MHC isoforms. METHODS: Six pregnant female rats were randomly divided into two groups: The hypothyroid group received water containing 6-propyl-2-thiouracil during gestation and the controls consumed tap water...

BACKGROUND: Familial adenomatous polyposis is a hereditary disease with autossomic and dominant features, frequently associated to many extracolonic manifestations. AIM: To report extracolonic manifestations incidence and to analyze its impact on the disease's outcome. PATIENTS AND METHODS: Revision of patient charts treated from 1977 to 2001, relating associated extracolonic manifestations and its complications. RESULTS: Among 59 familial adenomatous polyposis patients, 23 (38,9%) presented some extracolonic manifestations at diagnosis or during follow-up...

A study of 17 muscle biopsies from patients with myasthenia gravis was done, using freshfrozen section and histochemistry tecnics. It was found 15 abnormal muscle biopsies. The most common abnormality were small dark angular fibers, excess of lipids droplets outside the muscle membrane, changes in fiber size and type II fiber atrophy. These findings suggested denervation in 11 biopsies, type II fiber atrophy in 7, linfocyte infiltration in 4, fiber necrosis with fagocitosis in 1 and 2 were normal. Was noted a direct correlation between the disease duration and the severity of the histological abnormality...

COMPARATIVE STUDY
N I Dubinskaia, E B Burlakova
The highest increase in the mitotic index (MI) reticuloendothelial cells observed in the experiment after antioxidant treatment coincided in time with the maximal MI value of these cells in the untreated animals. However, the maximal increase of MI in hepatocytes took place when the minimal value of MI was registered in cells of the control animals. A significant increase in MI occurred both in hepatocytes and reticuloendothelial cells within the two first hours after antioxidant injection, but at this very time a more evident stimulation was observed for the hepatocytes...
