Prenatal bisphenol a and phthalate exposure are risk factors for male reproductive system development and cord blood sex hormone levels.

Bisphenol A (BPA) and phthalates can adversely affect the fetal development. However, observational studies on the effects of these chemicals on fetal male reproductive system are still limited. A hundred of umbilical cord blood samples were analyzed for the levels of BPA, di-2-ethylhexyl phthalate (DEHP), mono-2-ethylhexyl phthalate (MEHP), and sex hormones. After birth, male newborns underwent physical examination that included measurements of anogenital distance, stretched penile length (SPL), and penile width. BPA, DEHP and MEHP levels were detectable in ≈99% of cord blood samples. In covariate-adjusted models, cord blood BPA levels were inversely associated with SPL of newborns and positively associated with cord blood estradiol levels. In addition, there was a significant inverse relationship between cord blood DEHP levels and anogenital distance index of newborn males. Our results suggest that in utero BPA and DEHP exposure exerted adverse effects on fetal male reproductive development and cord blood estradiol levels

This paper summarizes the 5-year outcome. Methods: A team of instructors evaluated needs and held training activities in Turkey annually, and provided consultation when needed. Descriptive analysis was done via Excel and SPSS software. Results: Eighteen training activities were held with 3,570 attendees. Over the study period, the number of MDTs increased from 4 to 14. The MDTs got involved in organizing training activities in their institutions and communities. The number of medical curriculum lectures taught by MDTs to medical students/residents, conferences organized by the MDTs, and lectures to non-medical professional audiences increased significantly (R-2 = 91.4%, 83.8%, and 69.2%, respectively). The number of abuse cases assessed by the MDTs increased by five times compared to pre-training period. Conclusions: A culturally competent training program had a positive impact on professional attitudes and behaviors toward recognition and management of child abuse and neglect in Turkey. The need to partner with policy makers to revise current law in favor of a greater human services orientation became clear. Practice implications: Pioneers in developing countries may benefit from collaborating with culturally competent instructors from countries with more developed child protection systems to develop training programs so that professional development can improve recognition and management of child abuse and neglect.

Plasma Phthalate Levels in Pubertal Gynecomastia

OBJECTIVE: Several untoward health effects of phthalates, which are a group of industrial chemicals with many commercial uses including personal-care products and plastic materials, have been defined. The most commonly used, di-(2-ethylhexyl)-phthalate (DEHP), is known to have antiandrogenic or estrogenic effects or both. Mono-(2-ethylhexyl)-phthalate (MEHP) is the main metabolite of DEHP. In this study, we aimed to determine the plasma DEHP and MEHP levels in pubertal gynecomastia cases. PATIENTS AND METHODS: The study group comprised 40 newly diagnosed pubertal gynecomastia cases who were admitted to Hacettepe University Ihsan Dogramaci Children's Hospital. The control group comprised 21 age-matched children without gynecomastia or other endocrinologic disorder. Plasma DEHP and MEHP levels were measured by using high-performance liquid chromatography. Serum hormone levels were determined in some pubertal gynecomastia cases according to the physician's evaluation. RESULTS: Plasma DEHP and MEHP levels were found to be statistically significantly higher in the pubertal gynecomastia group compared with the control group (P<.001) (DEHP, 4.66 +/- 1.58 and 3.09 +/- 0.90 mu g/mL, respectively [odds ratio: 2.77 (95% confidence interval: 1.48-5.21)]; MEHP, 3.19 +/- 1.41 and 1.37 +/- 0.36 mu g/mL [odds ratio: 24.76 (95% confidence interval: 3.5-172.6)]). There was a statistically significant correlation between plasma DEHP and MEHP levels (r: 0.58; P < .001). In the pubertal gynecomastia group, no correlation could be determined between plasma DEHP and MEHP levels and any of the hormone levels. CONCLUSIONS: DEHP, which has antiandrogenic or estrogenic effects, may be an etiologic factor in pubertal gynecomastia. These results may pioneer larger-scale studies on the etiologic role of DEHP in pubertal gynecomastia. Pediatrics 2010; 125: e122-e129WoSScopu

Urinary bisphenol-A levels in children with type 1 diabetes mellitus

Background: Bisphenol-A (BPA) is one of the most abundantly produced chemicals globally. Concerns have been raised about BPA's possible role in the pathogenesis of type 1 diabetes mellitus (T1DM). The main aim of the current study was to evaluate the possible association between BPA exposure and T1DM. The second aim was to investigate children's possible BPA exposure routes in Turkey. Methods: A total of 100 children aged between 5 and 18 years including 50 children with T1DM and 50 healthy children were included. Urinary BPA levels of all children were measured using high-performance liquid chromatography. Mothers of children enrolled in the study were also requested to complete a survey that included questions on the sociodemographic characteristics, medical history and possible BPA exposure routes of their children. Results: In the T1DM group, urinary BPA levels were slightly higher compared to the control group, but this difference was not significant (p = 0.510). however, there was an inverse relationship between current urinary BPA levels and birth weight. It was found that the use of plastic kettles and the consumption of dairy products in plastic boxes significantly increased the urinary BPA concentrations in all subjects. Conclusions: Although there was no significant association between urinary BPA levels and T1DM, we found an inverse relationship between current urinary BPA levels and birth weight. This finding might be important for prenatal exposure, and further prospective research must be conducted. Also, the use of plastic kettles, which has not been mentioned much in the literature before, was found to be an important exposure route for BPA

Munchausen by Proxy Syndrome: A Case Series Study from Turkey

Munchausen syndrome by proxy (MSBP) is a rare form of child abuse in which a caregiver deliberately exaggerates, fabricates, and/or induces health problems in those in their care. The condition is extremely difficult to characterize and diagnose, as it manifests in many forms, often confusing the medical team. Insufficient knowledge regarding the syndrome and rare consideration of the differential diagnosis results in failure to recognize the problem. Literature suggests that an increase in physician awareness of the disorder can prevent or reduce its morbidity and mortality. For this reason, we believe that case series can help increase current knowledge on epidemiology, aetiology, diagnostic criteria, advised management of MSBP, and the psychological portrait of the perpetrator. Additionally, no data from Turkey has previously been presented on this issue. This study aimed to report characteristics of MSPB victims and alleged perpetrator, which were diagnosed and managed by a multidisciplinary team
