Prevalence of idiopathic intracranial hypertension and associated factors in obese children and adolescents.

Abstract Background: Idiopathic intracranial hypertension (IIH) is one of the most important and rare complications of obesity. Prevalence of IIH in childhood obesity is not known. The purpose of this study was to determine the prevalence of IIH in obese children and adolescents and to investigate the relevant factors. Methods: In this study, 1058 obese children and adolescents between 2 and 18 years of age were included. Funduscopic examination was conducted for all subjects. In cases with papilledema, increase in intracranial pressure was clarified by measuring CSF pressure with a lumbar puncture. Other causes of IIH were ruled out with clinical, laboratory tests and imaging techniques. Results: Idiopathic intracranial hypertension was diagnosed in 14 subjects (1.32%). Rates of headache and systemic hypertension in subjects with IIH was determined to be 78.6% and 28.6%, respectively. Morning cortisol, fasting insulin and HOMA-IR values were found to be significantly higher in this cases (p<0.05). Conclusions: In childhood obesity, IIH should be kept in mind as a serious complication. Funduscopic examination is an easy method that suggests IIH. In particular, obese children with systemic hypertension and refractory headache should be considered for IIH.

Chemopreventive effect of bilberry (Vaccinium myrtillus) against cisplatin-induced oxidative stress and DNA damage as shown by the comet assay in peripheral blood of rats

The aim of this study was to evaluate the chemopreventive effect of bilberry on cisplatin induced oxidative stress and DNA damage in rat blood. Twenty-one female Wistar-Albino rats were divided into three groups: group I — untreated; group II — treated with cisplatin (single dose 7.5 mg/kg b.w.); and group III — treated with cisplatin (single dose 7.5 mg/kg b.w.) and bilberry (200 mg/kg b.w. for 10 days). Antioxidant enzyme systems including superoxide dismutase, catalase, glutathione peroxidase and the level of malondialdehyde (MDA) that might occur on erythrocytes have been determined and single cell gel electrophoresis (comet) was utilized to evaluate the DNA damage in lymphocytes. Treatment with cisplatin has increased the levels of MDA and decreased antioxidant enzymes in erythrocytes. Comet assay showed significantly higher values at dose of 7.5 mg/kg cisplatin as the result of oxidative DNA damage when compared to the control group. Cisplatin treatment with bilberry resulted in a highly significant (P < 0.05) decreased in the lymphocytes DNA when compared to the cisplatin group. Bilberry has been effective on antioxidant enzyme systems and MDA level and significantly decreased the comets. Our results indicate that bilberry is capable of preventing genotoxic and cytotoxic damage caused by cisplatin in peripheral blood cells in rats.

A novel PTCH1 gene mutation in a pediatric patient associated multiple keratocystic odontogenic tumors of the jaws and Gorlin–Goltz syndrome

Gorlin–Goltz syndrome (GGS) is an uncommon autosomal dominant inherited disorder which comprises the triad of basal cell carcinomas (BCCs), odontogenic keratocysts, and musculoskeletal malformations. Besides this triad, neurological, ophthalmic, endocrine, and genital manifestations are known to be variable. It is occasionally associated with aggressive BCC and internal malignancies. This report documents a case of GGS with a novel mutation in the PTCH1 gene in an 11-year-old child. The clinical, radiographic, histopathologic and molecular findings of this condition, and treatment are described, and a review of GGS was carried out.

Sürmüş Kompaund Odontoma: İki Olgu Sunumu

126 Odontomalar histolojik olarak; mine, dentin, sement ve bazen pulpa dokusunu da içeren benign, mikst odontojenik tümör kategorisinde olmalarının yanı sıra, gelişimsel bir anomali olarak da değerlendirilebilir.1 Odontomaların görülme oranlarında cinsiyetler arasında bir fark belirlenmemiş olmasına rağmen, genellikle yaşamın ikinci dekadında ortaya çıktıkları saptanmıştır.2 Etiyolojisi ise travma veya lokal enfeksiyon gibi çeşitli patolojik durumlara veya herediter anomalilere (Gardner ve Hermann’s sendromu) dayandırılabilmekle birlikte, kesin bir nedene bağlanamamıştır.3,4 Sürmüş Kompaund Odontoma: İki Olgu Sunumu
