Glucose tolerance was evaluated in all patients without overt diabetes using the oral glucose tolerance test (OGTT). Six patients showed a pathological OGTT and 2 patients had insulin-requiring diabetes mellitus. The mean age of the patients with impaired glucose tolerance was significantly higher than that of the subjects with normal glucose metabolism (p<0.0001). Patients with overt diabetes mellitus were the oldest subjects in the study group.

T he aim of the study wa s to determine the knowledge level of adolescents about cancer and it's symptoms. The 9-12 th class students of two high schools were involved in the study. After getting informed consent 1311 students were asked to answer a questionnaire form. The mean age was 16.3 ± 1.12. The cases were grouped as Group 1 (adolescents without family members with cancer) and Group 2 (the cases that had family members with cancer). The awareness rates for all of nine common cancer signs were significantly higher in adolescents that had family members with cancer. The presence of a family member with cancer increased the rates of being aware but the increased awareness in that group did not change the attitudes towards possible presence of cancer symptoms.

Paraoxonase, arylesterase and glutathione-S-transferase are antioxidants that resist oxidative stress. In this study, we analyzed the changes in these enzymes during intoxication due to mushrooms. The study enrolled 49 adult patients with a diagnosis of mushroom poisoning according to clinical findings and 49 healthy volunteers as the control group. The patients with mild clinical findings were hospitalized due to the possibility that the patient had also eaten the mushrooms and due to clinical findings in the late period, which could be fatal. Paraoxonase, arylesterase, and glutathione-S-transferase concentrations, as well as total antioxidant and oxidant status, were determined in the 49 patients and 49 healthy volunteers by taking blood samples in the emergency department. While paraoxonase, arylesterase, and total antioxidant status were significantly decreased in the patient gr...

We aimed to determine the level of resistance to the antipseudomonal antibiotics, the change in the rates of antibiotic resistance over the years, and mortality rate during hospital stay. Methods: The microbiology database of P. aeruginosa isolated from 3708 sputum and 485 bronchial lavage samples at Chest Diseases Public Hospital from January 2009 to December 2013 was retrospectively reviewed. Imipenem, amikacin, tobramycin, ciprofloxacin, piperacillin, piperacillin/tazobactam ceftazidime, and cefepime resistance rates of P. aeruginosa strains were determined. Antimicrobial susceptibility was determined by the disk diffusion method, according to the Clinical Laboratory Standards Institute (CLSI) guidelines. P. aeruginosa was defined as resistant (resistance to at least one of the antipseudomonal antibiotics), and multidrug resistant (MDR) (resistance to three or more drugs of following classes: β-lactam, carbapenem, aminoglycoside, and fluoroquinolone). Results: Five hundred and five P. aeruginosa isolates were tested. The antibiotic resistance rates were as follows; cefepime (26.7%), ceftazidime (23.2%), piperacillin (22.2%), imipenem (21.8%), piperacillin/tazobactam (19.2%), ciprofloxacin (17.4%), tobramycin (11.9%), and amikacin (7.3%). When compared 2009 and 2013, statistically significant reduction was observed in resistance rates to ciprofloxacin, amikacin, and cefepime antibiotics. Among 505 strains, 12.1% were designated as being MDR. Out of 505 patients investigated, 34 (6.7%) died during the hospital stay. Conclusion: The clinical significance of these findings is important in the selection of appropriate empirical treatment of serious P. aeruginosa infections.

A cross-sectional type study was conducted between November 2004 and September 2006 in 200 driver and 200 non-driver persons. A complete ophthalmologic examination was performed, including visual acuity, and dilated examination of the posterior segment. We used the auto refractometer for determining refractive errors. According to eye examination results, the prevalence of the refractive error was 21.5% and 31.3% in study and control groups respectively (P<0.05). The most common type of refraction error in the study group was myopic astigmatism (8.3%) while in the control group simple myopia (12.8%). Prevalence of dyschromatopsia in the rivers, control group and total group was 2.2%, 2.8% and 2.6% respectively. A considerably high number of drivers are in lack of optimal visual acuity. Refraction errors in drivers may impair the traffic security.

We aimed to investigate whether the presence of Helicobacter pylori increases the bleeding or severity of Crimean Congo hemorrhagic fever. Materials and Methods: Forty-two patients with Crimean Congo hemorrhagic fever who had dyspepsia and were hospitalized between April 2009 and July 2009 were included in the study. The patients were divided into two groups according to their fecal Helicobacter pylori antigen positivity. Clinical and laboratory severity criteria for Crimean Congo hemorrhagic fever were investigated in both groups. Results: We could not find any difference between the two groups with regard to severity as defined by clinical and laboratory criteria. Conclusion: This is the first study in the literature investigating the role of Helicobacter pylori in the severity of Crimean Congo hemorrhagic fever from a country in which both Crimean Congo hemorrhagic fever and Helicobacter pylori are endemic. Further studies including a larger number of Crimean Congo hemorrhagic fever patients are necessary to recommend Helicobacter pylori screening and eradication in Crimean Congo hemorrhagic fever.

One of the still open issues for the development of superconductive insertion devices, is the understanding of the heat intake from the electron beam. COLDDIAG, a cold vacuum chamber for diagnostics was designed and built specifically for this purpose. With the equipped instrumentation, which covers temperature sensors, pressure gauges, mass spectrometers as well as retarding field analyzers it is possible to measure the beam heat load, total pressure, gas content as well as the flux of electrons and/or ions hitting the chamber walls. Here we report about the preliminary measurements and results of COLDDIAG installed in the Diamond Light Source.
