Prevalence of metabolic syndrome in schoolchildren and adolescents in Turkey: a population-based study.

AIM To determine prevalence of the metabolic syndrome (MS) in the pediatric population. METHODS We studied 2,491 schoolchildren randomly selected aged 10-19 years using a multistage, stratified sampling design. Obese and overweight participants were called for further investigation (n = 456). Of these, 310 participants underwent OGTT. MS was defined according to IDF, NCEP and modified WHO guidelines. RESULTS The prevalence of obesity and overweight were 6.8% and 11.5%, respectively. While MS was found in 2.3% of the total population according to IDF guidelines, its prevalence was increased among overweight and obese individuals. MS prevalence was similar by both IDF and NCEP definitions but higher according to WHO definition. Individuals with MS were consistent by both IDF and NCEP definitions (sensitivity = 100%, specificity = 99%, positive predictive value = 95.2%). IDF and WHO defined different individuals as having MS (sensitivity = 67.5%, specificity = 90%, positive predictive value = 67.5%). CONCLUSIONS Although not as high as in developed countries, MS prevalence determined in schoolchildren and adolescents in Turkey warrants preventive measures. MS diagnosis in one of every three obese children shows that MS is an important public health problem in Turkey as well.

Free vitamin D supplementation for every infant in Turkey.

We read with interest the article by Zipitis et al 1 concerning primary care trusts providing funds for vitamin D supplementation of Asian children for at least the first 2 years of life. Nutritional rickets remains prevalent in developing regions of the world such as Africa, the Indian subcontinent, Asia and the Middle East, and ranks among the five most common diseases in children.2–,4 The prevalence of nutritional rickets in developed countries also seems to be rising.5,6,7,8,9,10,11 In Turkey, nutritional rickets has long been among the leading diseases in childhood. Although the prevalence is not known, a recent study indicates that 6% of children <3 years of age presenting to a general outpatient clinic were found to have nutritional rickets.12 Maternal vitamin D deficiency is also endemic. Severe vitamin D deficiency was identified in 46–80% …

Evaluation of glucose intolerance in adolescents relative to adults with type 2 diabetes mellitus.

AIM There is an increasing trend in the prevalence of type 2 diabetes mellitus (DM2) in childhood and adolescence, while positive family history of DM2 and obesity are the most important risk factors. To study the influence of family history and obesity on glucose intolerance in our country was the aim of this study. STUDY DESIGN AND METHODS A total of 105 children and adolescents aged 10-18 years (mean 13.3 +/- 2.5 years) were included in the study. All children and adolescents were divided into three groups according to positive family history of DM2 and obesity, and an oral glucose tolerance test (OGTT) was performed for all. Prediabetes was defined as impaired glucose tolerance (IGT) and/or impaired fasting glucose (IFG). Insulin secretion and insulin resistance were estimated using the insulinogenic index; and the homeostatic model assessment for insulin resistance (HOMA-IR) and Matsuda index, respectively. RESULTS The prevalence of prediabetes was 15.2% in the whole group, while it was 25.5% in obese children who also had a positive family history of DM2. The frequency of hyperinsulinism was 57.1% in all groups. Prediabetic children had significant insulin resistance (HOMA-IR 11.5 +/- 7.1 and 4.1 +/- 6.4, respectively, p = 0.034). CONCLUSIONS Obesity and glucose intolerance are also a problem in developing countries. The risk of prediabetes in children is highest in obese children who also have a positive family history of DM2. There is a need for a lifelong preventive program starting in childhood to avoid DM2 and decrease cardiovascular risk factors

Prevention of Vitamin D deficiency in infancy: daily 400 IU vitamin D is sufficient

SummaryAim-objectiveVitamin D deficiency and rickets in developing countries continues to be a major health problem. Additionally, the increase of cases of rickets in children of some ethnic groups in the United States and European countries has provided this issue to be updated. Obviously, powerful strategies are necessary to prevent vitamin D deficiency nation-wide. In 2005, a nationwide prevention program for vitamin D deficiency was initiated, recommending 400 IU vitamin D per a day.This study was designed to evaluate the efficacy of the prevention program.MethodsEighty-five infants who were recalled as part of the national screening program for congenital hypothyroidism between February 2010 and August 2010 at Kocaeli University Childrens Hospital were evaluated in terms of their vitamin D status as well. All babies had been provided with free vitamin D (Cholecalciferol) solution and recommended to receive 400 IU (3 drops) daily. Information regarding the age at start of supplementation, the dosage and compliance were obtained from the mothers with face-to-face interview. Serum 25-hydroxy vitamin D (25-OH-D), alkaline phosphatase (AP), parathormone (PTH) levels were measured.ResultsThe mean age at which Vitamin D3 supplementation began was 16.5 ± 20.7 (3-120) days. Ninety percent of cases (n:76) were receiving 3 drops (400 IU) vitamin D3 per day as recommended; 70% of cases (n:59) were given vitamin D3 regularly, the remainder had imperfect compliance. Among those children who are older than 12 months, only 20% continued vitamin D supplementation. No subject had clinical signs of rickets. The mean 25-OH-D level was 42,5 ± 25,8 (median: 38.3) ng/ml. Ten subjects (12%) had their serum 25-OH-D levels lower than 20 ng/ml (6 between 15-20 ng/ml, 3 between 5-15 ng/ml and only one < 5 ng/ml).Conclusions400 U/day vitamin D seems adequate to prevent vitamin D deficiency. However, we believe that the program for preventing vitamin D deficiency in Turkey, needs to be reinforced to start immediately after birth, and to continue beyond 1 year of age at 400U regular daily dosage.

Influence of earthquake on the quality of life of patients with type 1 diabetes

We read with great interest the article by Wang et al.1 We would like to draw your attention to the results of our study which evaluated the impact of Marmara earthquakes (Turkey) on 17 August and 12 November 1999, on the quality of life (QoL) of our type 1 diabetic patients using the WHO Well Being Questionnaire (W-BQ). The study included a group of patients (n = 77; males 47%; age 24.2 ± 8.5 years) who had participated in a previous QoL study in October 1998 and they were affected by at least one of the quakes. For the new study, data were collected in the third month following the second quake and compared to results of the previous ones. In addition, metabolic control (HbA1c), body mass index and daily insulin requirement were assessed before and after earthquakes. In the meanwhile, the type of effect by the earthquake, socioeconomically and/or physically, was investigated via a questionnaire which was completed by the patients. According to our results,W-BQ scores were affected inversely by the quake. Mean total W-BQ score was decreased from 69 ± 13 to 44 ± 14 (P < 0.001). However, depression and anxiety scores increased significantly (prior and after the quake; 34 ± 14 vs 54 ± 13; P < 0.001 and 41 ± 18 vs 70 ± 19; P < 0.001, respectively). Our results also revealed the scores for positive well-being and energy decreased from 64 ± 21 to 36 ± 20 (P < 0.001) and from 73 ± 18 to 62 ± 20 (P = 0.008), respectively. When the data were compared before and after the quakes there was no difference for body mass index (23 ± 1.4 vs 23 ± 2.8 kg/m2). However, HbA1c (7.4 ± 1.5 vs 8.8 ± 2.5%; P < 0.001) and daily insulin requirement (0.58 ± 0.3 vs 0.75 ± 0.3 IU/kg per day; P < 0.001) were increased. Moreover, physical and/or socioeconomic impacts of the quake obtained from the questionnaire were not found to be changed in parallel to the psychological impact (DW-BQ scores) of the quake. Finally, we did not find any meaningful difference in W-BQ scores of the subgroups of those who were affected seriously or those who were affected minimally by the earthquake in terms of physical and socioeconomical levels. The fact may be explained by the limited number of injured people in the study cohort. Those who were not seriously affected still have a strong fear of a new quake.

Does common channel length affect surgical choice in female congenital adrenal hyperplasia patients

OBJECTIVE Partial/total urogenital sinus mobilization (UGSM) is one of the recommended techniques for treatment of female congenital adrenal hyperplasia (CAH). In this study we compared the length of common channel (CC) and type of operation performed in CAH patients. PATIENTS AND METHODS We retrospectively analyzed data of patients receiving surgery for female CAH. Patients were separated into three groups: group 1 had partial UGSM, group 2 had total UGSM, and group 3 had total UGSM plus the vaginal anterior wall was made from CC. Age at surgery, length of CC, surgical time, follow-up time, and complications were compared. RESULTS There were a total of 29 patients. For groups 1, 2, and 3, the average age at surgery was 47.2 months, 14.4 months, and 21.3 months, respectively, and the average CC length was 1.25 cm, 3.1 cm, 4.3 cm, respectively. The average time of surgery was 165 min, 193.1 min, 282.5 min, respectively. The average follow-up time was 34.7 months, 36.3 months, 28.3 months, respectively. There were two complications (UGS flap necrosis and opening of sutures) in the third group. CONCLUSION We advise the use of partial UGSM for CC of 0.5-2 cm, total UGSM for CC of 2.5-3.5 cm, and total USM with use of CC as the anterior vaginal wall in CC ≥ 4 cm in length. Good cosmetic and functional results are obtained with this approach.

Ovotesticular disorder of sexual development and a rare 46,XX/47,XXY karyotype

Abstract Ovotesticular disorder of sexual development (DSD) is characterized by the presence of both ovarian and testicular tissues in the same individual. The most common karyotype is 46,XX. Here, we report the case of a boy with a 46,XX/47,XXY karyotype diagnosed as ovotesticular DSD by gonadal biopsy. A 5-month-old boy presented with hypospadias, unilateral cryptorchidism, and a micropenis. Pelvic magnetic resonance imaging revealed a suspicious gonad tissue that is solid in structure in the right scrotum and a suspicious gonad that is cystic in structure in the left inguinal canal. He underwent a diagnostic laparoscopy. Cytogenetic analysis of peripheral blood revealed a 46,XX/47,XXY karyotype. Histopathologic examination of the left gonad showed ovarian tissue containing primordial follicles with ipsilateral undifferentiated tuba uterina. The right gonad showed immature testis tissue. He underwent left gonadectomy and hypospadias repair, and was raised as a male. Through this rare case, we highlight the importance of histological and cytogenetic investigation in DSD.

Two siblings with familial subclinical hyperthyroidism with unknown etiology

Subclinical hyperthyroidism is defined as low or undetectable concentration of serum thyrotrophin (TSH) with normal free triiodothyronine (FT3) and free thyroxine (FT4) levels. . Familial subclinical hyperthyroidism is a rare entity. Activating mutations of the TSH receptor (TSH-R) gene cause genetic hyperthyroidism. Here we present a family with more than one affected individual. All family members were investigated for TSH-R mutation. No mutation was detected, while a A459 polymorphism was found in one of the cases and three other siblings. Despite the clinical and biochemical findings suggesting a TSH-R mutation, a reasonable cause could not be detected. Epigenetic and environmental modifiers, including iodine intake, should be considered in families with mutation negative, familial non auto-immune hyperthyroidism (FNAH).
