The clinicopathological and prognostic significance of CD24, CD44, CD133, ALDH1 expressions in invasive ductal carcinoma of the breast: CD44/CD24 expression in breast cancer.

Background: Recently, there are several studies about cancer stem cells (CSC), indicating that they are the cells that initiate the tumor, provide progression, metastasis and responsible for the aggressive tumor behavior.

Materials And Methods: The purpose of this study is to investigate the expressions of CD24, CD44, their different combinations, ALDH1 and CD133 in invasive ductal carcinoma. Their relationships with clinicopathologic parameters, such as tumor grade, lymphovascular invasion, tumor size, axillary lymph node involvement, stage, hormone receptors, HER2 expression, basal like tumors, triple negative status and prognosis were also investigated.

Role of cytological characteristics of benign thyroid nodules on effectiveness of their treatment with levothyroxine.

Introduction: Levothyroxine (LT4) therapy has been used for the treatment of euthyroid nodular goiter, but there are controversial results about its usefulness. We aimed to evaluate the possible role of benign nodules' cytological characteristics in response to LT4 therapy.

Material And Methods: In total, 93 patients with 128 nodules were included in the study; 74 of the nodules were treated with LT4 (group 1), and 54 of them had no medication (group 2).

A clinical comparison of cordless and conventional displacement systems regarding clinical performance and impression quality.

Statement Of Problem: It is not clear whether newly introduced cordless displacement systems are better able to manage gingiva than conventional systems.

Purpose: The purpose of this in vivo study was to evaluate the gingival management ability of 4 different displacement methods with a standardized subgingival preparation finish line.

Material And Methods: The effects of 4 displacement techniques on gingival management and impression quality were evaluated by means of 6 evaluation criteria.

Body mass index, cholecystitis, cholelithiasis, pancreatitis and imaging of common bile duct stones.

Purpose: Studies to date have not investigated whether body mass index (BMI) affects the sensitivity and specificity of magnetic resonance cholangiopancreatography (MRCP). The purpose of this study was to investigate the effect of BMI and also concomitant pancreatitis, cholecystitis and cholelithiasis on the sensitivity and specificity of MRCP.

Materials And Methods: Between January 2004 and December 2011, 185 patients were included in the study and divided into 3 groups according to BMI as normal, overweight or obese.

Comparison of success and pain levels of supination-flexion and hyperpronation maneuvers in childhood nursemaid's elbow cases.

Objective: The aim of this study was to compare the hyperpronation (HP) and the supination-flexion (SF) reduction techniques for reducing nursemaid's elbow in terms of efficacy and pain.

Methods: This prospective, pseudorandomized, controlled, nonblinded study was conducted in an urban tertiary care emergency department between October 1, 2009, and October 1, 2010. A total of 150 patients (51 males [34%] and 99 females [66%] between the ages of 0 to 6 years) were included in the study.

Diagnostic accuracy of fine-needle aspiration cytology of palpable breast masses: an SROC curve with fixed and random effects linear meta-regression models.

We used various meta-analytic methods to compare 25 studies describing fine-needle aspiration (FNA) cytologic analyses performed from 1984 to 2007 on palpable breast masses. We found that in the 25 studies examined, the sensitivity ranged from 78% to 100%, the specificity ranged from 76% to 100%, and the diagnostic odds ratio (DOR) ranged from 15.83 to 33 198.
