Prevalence, comorbidities and mediators of childhood anxiety disorders in urban Turkey: a national representative epidemiological study.

PURPOSE: The aim of this study is to evaluate the prevalence of anxiety disorders, its correlation with sociodemographic characteristics, its comorbidities with other psychiatric disorders and its predictors in school-aged children. METHODS: This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014-2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version. Impairment is assessed by a 3-point Likert type scale independently by the parent and the teacher. The final sample included 5842 children with the mean age of 8.7 years. RESULTS: The prevalence of any anxiety disorder without considering impairment is 16.7% and considering impairment is 5.2% in children according to our study. We found significant differences for comorbid Attention Deficit Hyperactivity Disorder, Disruptive Behavior Disorder, Mood Disorders, Tic Disorders, Obsessive Compulsive Disorder, Enuresis Nocturna, Encopresis, and Intellectual Disability. Having a history of paternal physical disorder, living in the regions of Marmara, Mediterranean and Black Sea were found to be the main predictors of having childhood anxiety disorders according to the logistic regression analysis. CONCLUSION: Better understanding of childhood anxiety disorders, comorbid conditions and predictors will result in earlier diagnosis and more appropriate treatment.

The effect of penile urethral fat graft application on urethral angiogenesis.

BACKGROUND: Autologous fat grafts are rich in adipose-derived stem cells, providing optimal soft-tissue replacement and significant quantities of angiogenic growth factor. Although fat grafts (FG) are used in several clinical conditions, the use of FG in urethral repairs and the effects of FG to urethral repairs have not yet been reported. OBJECTIVE: An experimental study was performed to evaluate the effect of FG on urethral angiogenesis and tissue growth factor (GF) levels. STUDY DESIGN: Sixteen Wistar albino, adult, male rats were allocated into two groups: the control group (CG) (n = 8) and the experiment group (EG) (n = 8). After anesthetization of all rats, 3-mm vertical incisions were made on the urethras, and then sutured with interrupted 5/0 vicryl sutures. The operations were performed under a stereo dissecting microscope under magnification (×20). In the CG, no additional procedure was performed. In the EG after the same surgical procedure, 1 mm(3) FG was removed from the inguinal region by sharp dissection with a knife. The grafts were trimmed to 1 × 1 mm dimensions on millimeter paper. The FGs were placed on the repaired urethras. The skin was then closed. Samples from urethral and penile skin were taken 21 days after surgery in both groups. Density and intensity of staining with vascular-endothelial GF (VEGF), VEGF-receptor, and endothelial-GF receptor (EGFR) in the endothelial and mesenchymal cells of the penile urethral vessels were immunohistochemically evaluated. Data obtained from immunohistochemical evaluations were analyzed with SPSS 15.0. The P-values lower than 0.05 were considered as significant. RESULTS: Density of VEGF staining was significantly decreased in the vascular endothelium of the EG compared to the CG (P < 0.05). Density of the EGFR staining was significantly decreased in the vascular endothelium of the EG compared to the CG (P < 0.05) (Table). Intensity of VEGF, VEGF-R and EGFR staining was not significantly different between the two groups. There were no significant differences between groups regarding to VEGFR staining and mesenchymal examination. DISCUSSION: Decreased density was found in the VEGF staining in the vascular endothelium. This could be explained by the day that the tissues were harvested or because autologous fat grafts might cause decreased growth factor levels, which is contrary to the literature data. CONCLUSION: Fat grafting has an immunohistochemical effect on the growth factor levels that are related to angiogenesis after urethral repair. It is difficult to make a firm conclusion about the role of fat grafting on urethral healing. Therefore, future studies are needed to see if FG can be used as an alternative to other procedures in order to avoid complications.

Specimen radiography: an assessment method for reduction mammaplasty materials.

Although, one out of every eight women has a risk of developing breast cancer, the reported incidence of breast carcinoma detection in reduction mammaplasty materials is rather low. To our knowledge, specimen radiography, which is used for breast biopsies has not been used for the assessment of breast reduction materials. We investigated the applicability of specimen radiography and its potential benefits in detection of the breast pathologies, especially malignancies in reduction mammaplasty materials. Forty patients scheduled for reduction mammaplasty operation were included. In all cases an inferior pedicle reduction technique was preferred and the radiographs of the resected breast tissues were taken immediately. The radiographs were evaluated for any possible pathologic appearance and all abnormal findings were marked. For the histopathologic evaluation, in addition to the random sampling of the pathologist, any marked areas were also microscopically examined. In two cases fibrocystic changes were found in radiographs and the same results were obtained in the histological examination. No false negative mammogram was seen. Specimen radiography, which is applicable for breast reduction materials is an easy and cheap method and does not cause any patient discomfort. It seems that the radiographs of reduction mammaplasty materials are useful to provide guidance to the pathologist during tissue sampling for microscopic examination especially when large amounts of breast tissue is excised.
