The F-18 FDG PET/CT and CT evaluation of pleural plaques.

Introduction: Pleural plaques have the possibility of bearing malignancy thus investigation of this entity is important and the most important indicator of malignancy in general is fluorodeoxyglucose (FDG) accumulation in radiological appearance. However there is discrepancy between results of previous studies in the literature about this subject. The aim of this study is to analyze the standardized uptake value of pleural plaques and the cut off levels for malignancy in comparison with computed tomography (CT).

Alternative Confidence Interval Methods Used in the Diagnostic Accuracy Studies.

Background/Aim. It is necessary to decide whether the newly improved methods are better than the standard or reference test or not. To decide whether the new diagnostics test is better than the gold standard test/imperfect standard test, the differences of estimated sensitivity/specificity are calculated with the help of information obtained from samples.

Mesenchymal stem cell treatment in hyperoxia-induced lung injury in newborn rats.

Background: The aim of this study was to evaluate the effectiveness of tracheally delivered mesenchymal stem cells (MSC) on lung pathology in a hyperoxia-induced lung injury (HILI) model in neonatal rats.

Methods: For the HILI model, rat pups were exposed to 85-95% oxygen during the first 10 days of life. Rats were divided into six groups: room-air normoxia (n = 11); room air, sham (n = 11); hyperoxia exposed with normal saline as placebo (n = 9); hyperoxia exposed with culture medium of MSC (n = 10); hyperoxia exposed with medium remaining after harvesting of MSC (n = 8); and hyperoxia exposed with MSC (n = 17).

Cultural adaptation of the Michigan Hand Outcomes Questionnaire in patients with Carpal Tunnel Syndrome: A Turkish version study.

Objective: Cultural adaptations of the questionnaires are important for easy use. We aimed to assess the reliability and validity of the Turkish Version of the Michigan Hand Outcomes Questionnaire in patients with Carpal Tunnel Syndrome.

Methods: To assess test-retest reliability, the Turkish "Michigan Hand Outcomes Questionnaire" and "Disabilities of Arm, Shoulder and Hand" questionnaires were answered by patients and controls and were repeated a week later.

Warthin's tumor: an unknown pathogenesis: a neoplasm or a reactive hyperplasia?

Background And Aims: To examine the probable role of angiogenesis and lymphangiogenesis in the pathogenesis of Warthin's tumor.

Materials And Methods: Sixty-one patients with Warthin's tumor (n = 40), branchial cysts (n = 6), thymic cysts (n = 3), or tonsillar lymphoepithelial cysts (n = 12) were included. Forty Warthin's tumors were used as the lesion group, and 21 lymphoepithelial cysts were used as a control group.

The diagnostic value of diffusion-weighted imaging and the apparent diffusion coefficient values in the differentiation of benign and malignant breast lesions.

Introduction: The goal of our study was to evaluate the diagnostic efficacy of diffusion-weighted imaging (DWI) in the differentiation of benign and malignant breast lesions.

Methods: Between June 2012 and March 2013, 60 patients with 63 lesions (age range 29-70 years, mean age 48.6 years) were included in our study.

Gender influences headache characteristics with increasing age in migraine patients.

Background And Aims: Migraine headache is one of the most common primary headache disorders and is three times more prevalent in women than in men, especially during the reproductive ages. The neurobiological basis of the female dominance has been partly established. The present study aimed to investigate the effect of gender on the headache manifestations in migraine patients.

Contribution of DOG1 expression to the diagnosis of gastrointestinal stromal tumors.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract, and the majority contain KIT or PDGFRA-activating mutations. However, up to 10% of GISTs are c-kit-negative. Antibodies with increased sensitivity and specificity for the detection of c-kit-negative GIST cases may be of value, especially because some of these cases may also benefit from tyrosine kinase inhibitor therapy.
