Evaluation of circulating cell-free nucleic acids in health workers occupationally exposed to ionizing radiation.

Radiology workers might constantly be exposed to low-dose ionizing radiation due to their profession. Low doses of radiation in a short exposure time have the potential to alter the genome, which might potentially lead to diseases. The main objective of this study was to determine whether the amount of cell-free nucleic acids in plasma samples of radiation-exposed workers was different from the general public, in other words, non-exposed individuals.

Patterns of motor branching of the musculocutaneous nerve in human fetuses and clinical significance.

The purpose of this morphologic study is to investigate the course and the branching pattern of motor branches of musculocutaneous nerve (MCN) in human fetuses. Twenty upper limbs (10 right, 10 left) of spontaneously aborted formalin-fixed fetuses were dissected under a stereomicroscope to determine motor branches for the biceps brachii and brachialis and the communicating branches between the MCN and median nerve (MN). The MCN entered the proximal and middle part of coracobrachialis in 13/20 and 5/20 of arms, respectively, and the remaining 2/20 did not pierce coracobrachialis.

[Analysis of genetic penetrance in the pedigree of cases with Van der Woude syndrome: report of five cases].

Van der Woude syndrome is a congenital abnormality characterized by labial cysts, accessory salivary glands, pits, fistulas and paramedian sinuses of the lower lips, and is frequently associated with cleft lip and palate. This disease is the most common syndromic cleft abnormality. The disease is characterized by a single gene abnormality where craniofacial morphogenesis is affected.

Distraction osteogenesis is inhibited by cancer radiotherapy with Co 60.

Aim: To investigate the effects of radiotherapy on distraction osteogenesis performed on the same bone in an area that has not received radiation. Radiotherapy (Co60) was carried out in a region where tumors may develop, and then, on the assumption that the tumoral region had been removed, distraction osteogenesis was carried out, and the effects were investigated.

Method: Thirty New Zealand rabbits were randomized into two groups, a study group (15 rabbits) and a control group (15 rabbits).

Whole-body exposure of radiation emitted from 900 MHz mobile phones does not seem to affect the levels of anti-apoptotic bcl-2 protein.

The purpose of the present study was to investigate the anti-apoptotic bcl-2 protein in rat brain and testes after whole-body exposure to radiation emitted from 900 MHz cellular phones. Two groups (sham and experimental) of Sprague-Dawley rats of eight rats each were used in the study. Exposure began approximately 10 min after transferring into the exposure cages, a period of time when rats settled down to a prone position and selected a fixed location inside the cage spontaneously.

Mucormycosis is a rare, saprophytic, invasive, and fulminant fungal disease. It occurs in immunocompromised patients such as those with diabetes mellitus or blood dyscrasia, or in patients under immunosuppressive therapy. A 17-year-old female patient with diabetic ketoacidosis presented with a black-colored lesion in the auricle and external ear canal.

Does adding misoprostol to standard intravenous proton pump inhibitor protocol improve the outcome of aspirin/NSAID-induced upper gastrointestinal bleeding?: a randomized prospective study.

Aspirin and nonsteroidal anti-inflammatory drug (NSAID)-induced gastrointestinal bleeding is recognized as an important health problem. We performed a single-center randomized clinical trial to compare the effect of high-dose intravenous proton pump inhibitor (omeprazole) alone (group 1) with omeprazole in combination with a low-dose prostaglandin analog (misoprostol; group 2) on clinical outcomes in patients with aspirin/NSAID-induced upper gastrointestinal bleeding. Additionally, we evaluated the contribution of Helicobacter pylori eradication therapy on the late consequences.

A proposal for a new and more practical grading scheme for pancreatic ductal adenocarcinoma.

There is no uniformly applied grading system for pancreatic ductal adenocarcinoma (DA). The scheme advocated by the WHO is essentially that of Kloppel et al, and is based on the "highest grade" focus. Although it is precise with good prognostic value, it is unfortunately not widely applied, largely because of the lack of recognition and partly because of its complex nature (interpretation of multiple parameters).

Evaluation of optimal gastric mucosal biopsy site and number for identification of Helicobacter pylori, gastric atrophy and intestinal metaplasia.

Background/aims: The study is designed to identify the optimal gastric mucosal biopsy site and number for identification of Helicobacter pylori, gastric atrophy and intestinal metaplasia.

Methodology: Ninety-two patients were included in the study, gastric biopsies were obtained from 5 different sites: lesser curvature of the mid-antrum (A1), greater curvature of the mid-antrum (A2), incisura angularis (IA), lesser curvature of the mid-corpus (B1), greater curvature of the mid-corpus (B2). Helicobacter pylori was evaluated in sections stained with toluidine blue, and histopathological examination was performed in sections stained with hematoxylin-eosin.

Strong association of HMB-45 expression with renal angiomyolipoma.

Objective: Angiomyolipoma (AML) is a benign neoplasm consisting of varying mixtures of smooth muscle, blood vessels and fat. Although, most of these tumors are easy to recognize, some may pose a diagnostic dilemma due to unusual histologic features. Recently, it was suggested that melanosome-associated protein (HMB-45) immunoreactivity may be used for diagnostic confirmation of several neoplasm.
