Identification of candidate genes in a family with cancer overload by whole-exome sequencing.

BACKGROUND: Approximately 120 out of every 1 million children in the world develop cancer each year. In Turkey, 2500-3000 children are diagnosed with new cancer each year. The causes of childhood cancer have been studied for many years. It is known that many cancers in children, as in adults, cause uncontrolled cell growth, and develop as a result of mutations in genes that cause cancer. METHODS: The investigation of family history within this context in the study, a total of 13 individuals consisting of all children and adults in the family were examined using the whole-exome sequencing (WES) with the individuals who were diagnosed with cancer in the family, who were detected to have different cancer profiles, and defined as high risk and to determine the gene or genes through which the disease has developed. RESULTS: At the end of the study, a total of 30 variants with a pathogenic record in the family were identified. A total of 10 pathogenic variants belonging to 8 different genes from these variants have been associated with various cancer risks. CONCLUSIONS: A significant scientific contribution has been made to the mechanism of disease formation by studying a family with a high cancer burden and by finding the genes associated with the disease. In addition, by the results obtained, family members with cancer predisposition were selected after a risk analysis conducted in this family, and the necessary examinations and scans were recommended to provide an early diagnostic advantage.

Treatment of female pattern hair loss.

Female pattern hair loss (FPHL) as a distinctive entity was first described about 30 years ago. The objective of this study was to perform a systematic review of all randomized controlled trials for treatment of FPHL. A preliminary search was carried out in several databases up to August 2008 to identify all randomized controlled trials on nonsurgical interventions for treatment of FPHL. Studies reporting fewer than 10 patients and non-English articles were excluded. Additionally, references of relevant articles and reviews were checked manually in search for additional sources. Among 238 citations found in the preliminary search, 12 fulfilled all criteria to be included in the systematic review. Topical minoxidil 1% to 5% for 24 to 48 weeks was shown to be effective in FPHL and its effect was not related to age or androgen level of patients. In addition, it may be effective in women with FPHL, both with and without hyperandrogenism, and in young and old premenopausal or postmenopausal. In patients with increased serum androgens, oral flutamide but not finasteride or cyproterone acetate was more effective than no treatment. Topical minoxidil is effective in patients with FPHL, with or without hyperandrogenism, but there is limited evidence for the efficacy of antiandrogens.
