Although to be prevalence of onychomycosis in school children in central Anatolia of Turkey seems very low degree, pediatric onychomycosis is a growing public health concern all over the world. Children having more siblings or unemployed fathers and children living in small house as well as older children should be examined carefully for onychomycosis.
Objective: The aim of this study is to provide normative data about pituitary diameters in a pediatric population. Pituitary imaging is important for the evaluation of the hypothalamo-pituitary axis defect. However, data about normal pituitary gland diameters and stalk are limited, especially in children. Structure and the measurements of pituitary gland and pituitary stalk may change due to infection, inflammation, or neoplasia. Methods: Among 14,854 cranial/pituitary gland magnetic resonance imaging scans performed from 2011 to 2013, 2755 images of Turkish children aged between 0 and 18 were acquired. After exclusions, 517 images were left. Four radiologists were educated by an experienced pediatric radiologist for the measurement and assessment of the pituitary gland and pituitary stalk. Twenty cases were measured by all radiologists for a pilot study and there was no interobserver variability. Results: There were 10-22 children in each age group. The maximum median height of the pituitary gland was 8.48 ± 1.08 and 6.19 ± 0.88 mm for girls and boys, respectively. Volumes were also correlated with gender similar to height. Minimum median height was 3.91 ± 0.75 mm for girls and 3.81 ± 0.68 mm for boys. The maximum and minimum pituitary stalk basilar artery ratios for girls were 0.73 ± 0.12 and 0.59 ± 0.10 mm. The ratios for boys were 0.70 ± 0.12 and 0.56 ± 0.11 mm. Conclusion: Our study demonstrated the pituitary gland and stalk size data of children in various age groups from newborn to adolescent. It is thought that these data can be applied in clinical practice. Future prospective followup studies with larger samples, which correlate the structural findings with the clinical and laboratory results are awaited.
Serum sTREM-1, IL-6, endocan levels, and I/T ratio increased in septic neonates. However, the diagnostic accuracy of circulating sTREM-1 seemed to be better than endocan and I/T ratio, but lower than IL-6.
Objective: The aim of this study was to investigate the prevalence and risk factors of pediculosis capitis in schoolchildren living in rural and urban areas in Kayseri, a city located in central Anatolia in Turkey.Methods: This cross-sectional school-based study was performed in 24 randomly selected public schools. A total of 8,122 schoolchildren aged 5-16 years, from kindergarten to eighth grade, were examined for the presence of pediculosis capitis. A child was defined as being infested by the presence of live or dead lice or eggs/nits. The results were analyzed using the chi-squared test and logistic regression analysis.Results: The overall prevalence of head lice infestation was 13.1%. Pediculosis was more frequent in girls (25.2%) than in boys (0.86%) (p<0.001). The prevalence was lower in children aged 5-8 years than in those aged 9-11 or 12-16 years (p<0.001). In multiple regression analyses, the variables demonstrating statistically significant association with pediculosis were: being a girl (OR=40.93; 95% CI=29.06-57.66), being 9-11 years old (OR=1.54; 95% CI=1.25-1.89), residing with ≥ 3 siblings (OR=1.98; 95% CI=1.57-2.50), having a mother with no education (OR=1.73; 95% CI=1.29-2.33), having a father with no education (OR=1.45; 95% CI=1.08-1.94), living in a rural area (OR=2.34; 95% CI=2.02-2.71) and living in a one-room house (OR=2.39; 95% CI=1.41-4.08).Conclusions: Pediculosis capitis remains a health problem in schoolchildren in Kayseri, Turkey. In addition to improvement in socioeconomic status, collaborative and participation efforts among physicians, nurses, teachers, and parents are necessary to maintain effective epidemiological surveillance and provide treatment.
Serum CXCR4 and CXCL12 levels increase in septic neonates and that both chemokines decrease within 48-72 h of treatment. Serum concentrations of both chemokines represent promising novel biomarkers for neonatal sepsis.
Ventricle sizes are important for the early diagnosis of hydrocephalus or for follow-up after ventriculostomy. Diameters of ventricles may change, especially in childhood. This study aims to provide normative data about ventricle diameters. Among 14,854 cranial MRI performed between 2011 and 2013, 2,755 images of Turkish children aged 0-18 years were obtained. After exclusions, 517 images were left. Four radiologists were trained by a pediatric radiologist. Twenty images were assessed by all radiologists for a pilot study to see that there was no interobserver variation. There were 10-22 children in each age group. The maximum width of the third ventricle was 5.54 ± 1.29 mm in males in age group 1 and 4.98 ± 1.08 mm in females in age group 2. The Evans' index was <0.3 and consistent with the literature. The third ventricle/basilar artery width ratio was found to be >1 and <2 in all age groups and both gender groups. Our study showed the ventricle size data of children in various age groups from newborn to adolescent. The ventricle volume/cerebral parenchyma ratio seems to decrease with age. We think that these data can be applied in clinical practice, especially for the early diagnosis of hydrocephalus.
Procarbazine (P) is an effective chemotherapeutic drug especially used in lymphoma treatment; however testicular toxicity is a limiting factor. Various ways of treatment were tried to preserve testicular function including hormonal treatment, antioxidant treatment, and sperm cryopreservation but resulted with low rates of satisfaction. Procarbazine is a well known agent causing sterility even in the first doses of chemotherapy. Antioxidants such as N acetylcysteine and ascorbate have been used for protective purposes and were very successful. Melatonin (M) is another powerful antioxidant and we aimed to use M for the protection of P induced testicular toxicity in this study. Procarbazine was given peroral by gavage once a week at a dose of 62.5 mg/kg/week for 4 weeks (total dose: 250 mg/kg) (P group) and in procarbazine + melatonin (PM) group, 10 mg/kg melatonin was intraperitoneally administered daily for five days a week for 4 weeks (total 20 days). The experiment ended at day 90. In the P and PM groups the testicle width, length, and weight, sperm A and sperm AB properties (Sperm A: sperms straight line progressive, Sperm B: sperms straight slow progressive, Sperm AB: Sperm A + Sperm B), spermatogonia, Sertoli cells, seminiferous tubule, and germinative layer thickness were lowered as compared with the control group. However, there were no significant differences between the P and PM groups in regard to these parameters. Melatonin preserved Sertoli cell and spermatogonia function. The testosterone and follicle-stimulating hormone (FSH) levels were also preserved. Melatonin significantly decreased malondialdehyde (MDA) levels and preserved the antioxidant enzyme levels such as glutathione peroxidase (GPx) and nitrite nitrate (NO2-/NO3-). Melatonin may protect testicular functions in P treated patients and is open to consideration during chemotherapy since it appears to be without any side effects.
