Objective-Thalamic abnormalities have been reported in people with pervasive developmental disorders (PDD) including Asperger’s Disorder (ASP). The aim of the present study was to compare the volume and volume fraction of the thalamus and the metabolite concentrations in children and adolescents with ASP using the magnetic resonance imaging and proton magnetic resonance spectroscopy. Additionally, the relationships between thalamic abnormalities and clinical features were examined. Methods-Volume and volume fractional and metabolic measurements of bilateral thalamus were collected from 15 boys with ASP with a total IQ over 70 (age range 7–18 years, mean age 11.6±3.79 years), and 15 healthy controls matching age, sex and IQ. The thalamic volumes, hemisphere volumes and total brain volumes (TBV) were estimated using the stereological methods on magnetic resonance images. Chemical metabolites of thalamus were evaluated by 1H spectroscopy. Results-No differences in thalamic volumes, volume fractions and metabolites were observed between the groups. There were significant correlation between thalamic volume and total brain volume in both groups. The ASP group showed a significant left-minus-right thalamus difference as well as a significantly greater laterality index. In addition, a significant correlation between the laterality index and Autism Behavior Checklist language scores was observed. Conclusion-Findings from this investigation point to a significant increase in laterality of the thalamus and a relationship with language problems in individuals with ASP. Our findings suggest that thalamic abnormalities may be related to mild language problems observed in ASP.

Background: The aim was to determine the lifestyle behaviors and the practices for early diagnosis of cancer of cancer patients. Materials and Methods: A descriptive cross-sectional design was used for this study. The sample consisted of 222 patients with a diagnosis of cancer (non-random sample method). Ethical permission was obtained of the Non-interventional Research Ethics Committee of our Institution. Values of p<0.05 were accepted as statistically significant. Results: It was observed that 54.4% of the patients had never performed breast self-examination, 60.8% had never had a mammography, and 71.2% had never had a Pap smear. Sixty-six point two percent of patients had never had screening for colon cancer within the past ten years. GIS cancers were higher in smokers and ex-smokers (p=0.005), in drinkers and in ex-drinkers (p=0.000). The breast cancer rate was higher in obese people (p=0.019). Conclusions: The results of this study provide information on the healthy lifestyle behavior of cancer patients before their diagnosis, and their use of early diagnosis practices. The important aspect of this study is to extend cancer patients' period of life after the diagnosis and treatment process, to make them conscious of risky lifestyle and nutritional behavior so that they can maintain a high quality of life, and to start initiatives in this direction that would ensure changes in behavior.

Background: The pathogenesis and etiology of endometrial polyps has not been elucidated. In this study, we aimed to examine the pathogenic mechanisms of endometrial polyp development using immunohistochemistry. We evaluated the expression of galectin-3 and cyclooxgenase-2 (COX-2) during the menstrual cycle in premenopausal women with endometrial polyps or normal endometrium. Methods: Thirty-one patients with endometrial polyps and 50 healthy control patients were included in this study. The levels of expression of COX-2 and galectin-3 were studied by immunohistochemistry. Results: The percentage of COX-2–positive cells and the intensity of COX-2 staining in the endometrium did not vary during the menstrual cycle either in the control group or in patients with endometrial polyps. However, expression of galectin-3 was significantly lower in endometrial polyps and during the proliferative phase of the endometrium compared with the secretory phase. Conclusions: Our data suggests that the pathogenesis of endometrial polyps does not involve expression of COX-2 or galectin-3.
