Objective: Obesity is a common epidemic issue in all over the world. In order to prevent obesity it is essential to know about obesity and its detrimental consequences. This study aimed to evaluate children's awareness about obesity and to determine the associations between level of awareness, healthy lifestyle, dietary habits and risk factors for metabolic syndrome. Methods: Two hundred and thirty-six overweight children (119 boys and 117 girls) aged 10-14 years were enrolled to the study. Anthropometric and biochemical measurements were taken and metabolic syndrome (MetS) definition were done according to the International Diabetes Federation (IDF) consensus and divided into two groups as MetS (+) and MetS (-). Obesity awareness scale (OBA) and Adapted Healthy Lifestyle-Diet Index for Turkey (HLD-TR) were performed. Results: Among children, the prevalence of having MetS was found as 26.3%. Obesity awareness and HLD-TR index sores were lower in MetS (+) group than MetS (-) group. Metabolic syndrome related biochemical parameters and anthropometric measurements were associated with obesity awareness level of the children. The binary logistic regression model shows that a one-unit increase in the OBA index score increases the odd of not having MetS for 1.12 times after adjustments for age, gender, body mass index, and HLD-TR index score. Conclusions: Increased awareness about obesity among children will help to reduce the risk of metabolic syndrome, type 2 diabetes and atherosclerotic cardiovascular diseases in the future.

Kistik fibrozis ile ilişkili diyabet (KFİD), kistik fibrozisin (KF) yaygın bir komplikasyonudur. Kistik fibrozis ile ilişkili diyabetin temel nedeni hastalarda yıllar içerisinde pankreas hasarının artması ile beraber pankreas adacık hücrelerinin kaybı ve insülin eksikliğinin gelişmesidir. Tedavideki amaç çocuk ve adolesanlarda normal büyüme ve gelişmenin ve kan glukoz regülasyonunun sağlanmasıdır. Tedavinin temelini insülin tedavisi ve tıbbi beslenme tedavisi oluşturur. İnsülin tedavisi, KFİD hastalarında akciğer fonksiyonunu stabilize eder ve beslenme durumunu iyileştirir. Kistik fibrozis ile ilişkili diyabetli hastalara yüksek enerji, yüksek yağ ve yüksek tuz içeren bir beslenme planı önerilmektedir. Karbonhidrat sayımı, insülin tedavisi alan hastalarda öğün öncesi insülin dozunun belirlenmesinde yararlıdır. Bu yazıda kliniğimizde izlenen KFİD’li bir çocuk olgunun medikal ve tıbbi beslenme tedavisi literatür derlemesi eşliğinde sunulmuştur.

Objective: Soluble endoglin (S-endoglin) has been implicated as a potential marker of endothelial dysfunction (ED) and was reported to be elevated in diabetic adults, correlating with the severity of diabetic vasculopathy. However, circulating S-endoglin and its association with other markers of ED have not been formerly analyzed in the first decade of diabetes onset in adolescents with type 1 diabetes mellitus (T1DM). Methods: Fifty-eight adolescents with moderately/poorly controlled T1DM were included in this study and twenty-nine healthy adolescents served as controls. The diabetic group was divided into two groups based on the presence of microalbuminuria, as the microalbuminuria group (n=15) and the normoalbuminuria group (n=43). Functional vascular alterations were evaluated by measuring serum S-endoglin and plasma nitric oxide (NO) concentrations, the flow-mediated dilatation (FMD) of the brachial artery. Carotid intima media thickness (CIMT) was measured for evaluation of structural vascular alterations. Results: The S-endoglin and NO levels of both microalbuminuria and normoalbuminuria groups were higher than those of the control group (for S-endoglin, p=0.047 and p

Individuals with 45,X/46,XY karyotype are at increased risk for germ cell tumor development. We report a case with a diagnosis of 45, X/46, XY gonadal dysgenesis who presented with short stature, physical stigmata of Turner syndrome. Her pubertal development was at Tanner stage 3. At follow-up, bilateral prophylactic gonadectomy was performed when considering the risk factors. Pathological assessment was consistent with gonadoblastoma in the left gonad, and dysgerminoma and gonadoblastoma in neighboring areas in the right gonad. The karyotype analysis of the right and left gonadal tissues reveled 45,X[97,3]/46,XY[2,7] and 45,X[92,7]/46,XY[4,5]/47,XYY [2,8] mosaic, respectively. The clinical management of such patient should be individualized according to the present risk factors. Additionally, signs of estrogenization like advanced breast development always suggest the possible presence of germ cell tumor.

Cardio-facio-cutaneous (CFC) syndrome is a rare disorder characterized by craniofacial dysmorphia, ectodermal abnormalities, cardiac malformations, as well as growth and developmental delay. Although some endocrine abnormalities have been reported in this syndrome, very little is known about CFC syndrome-related endocrine disorders. A 7.5-year-old boy was admitted to our endocrinology clinic with the complaint of short stature. He had a height of 103 cm [-4 standard deviation (SD)], a weight of 16 kg (3(th) percentile, -1.7 SD), a facial appearance typical for the CFC syndrome, optic nerve hypoplasia and pulmonary stenosis. Genetic investigation revealed a heterozygous mutation in exon 3 of the MEK1 gene, c.389AG (p. Y130C). During his long-term follow-up, the patient developed a variety of endocrine disorders including precocious puberty, growth hormone deficiency and hyperprolactinemia.

Background:The aim of this study was to investigate the early signs of atherosclerosis and to evaluate serum endoglin and obestatin levels as predictors of subclinical atherosclerosis in obese children.Methods:A total of 95 children (60 obese and 35 controls) aged 10–18 years were included in the study. Their endoglin and obestatin levels and biochemical parameters were measured. The carotid intima media thickness (cIMT) and brachial artery flow-mediated dilatation (FMD) responses were evaluated.Results:The cIMT values were higher (p < 0.001) and FMD responses were lower (p = 0.003) in the obese group than in the control group. A logistic regression multivariate analysis revealed that cIMT was independently associated with the body mass index (BMI) Z-score (β = 0.323, p = 0.003) and low density lipoprotein (LDL) (β = 0.29, p = 0.008), while FMD % was independently associated with waist circumference (β = −0.36, p = 0.002). The obese and control groups were similar in endoglin (p = 0.67) and obestatin levels (p = 0.70). The endoglin level was inversely correlated with the cholesterol and LDL levels (r = −0.23, p = 0.032; rho = −0.25, p = 0.019).Conclusions:The cIMT and brachial artery FMD response in obese children are significantly different compared to healthy controls. Circulating endoglin and obestatin levels are not predictive markers for subclinical atherosclerosis in obese children aged 10–18 years old.

Arachnoid cysts (ACs), particularly suprasellar cysts, cause a wide spectrum of endocrine disorders. Herein, we report two patients diagnosed with an extensive AC in the middle cranial fossa while being investigated for etiologies of precocious puberty and short stature. One of them required surgery due to his pubertal disorders associated with compression effects of cyst. After surgery, his puberty progression was regressed within one year. On the other hand, surgery was not planned for the second patient considering of his cranial imaging findings and the extremely low incidence of growth hormone (GH) deficiency caused by middle fossa AC (MFAC). We started treatment with recombinant human GH and no complication was found during treatment follow-up. Endocrine disorders associated with MFACs are extremely rare. By presenting with these two cases, we aimed to remain our fellow physcians that ACs can be possibly cause of endocrine disorders. Clinicians should be careful evaluating endocrine disorders because real cause may not be cyst itself but masked by it.

To investigate whether there is a change in bone turnover-related biochemical markers and bone mineral density of children with constitutional delay of growth and puberty (CDGP) in the prepubertal period.We measured serum calcium, phosphorus, alkaline phosphatase, parathormone, 25-OH vitamin D, osteocalcin, osteoprotogerin and urinary deoxypyridinoline levels (D-pyd), and bone mineral density (BMD) in 31 prepubertal boys with CDGP. These children were compared with 22 prepubertal boys with familial short stature (FSS) and 27 normal prepubertal boys.Urinary D-pyd was significantly high in CDGP group as compared to control group (p=0.010). Volumetric BMD did not significantly differ between CDGP, FSS, and control groups (p=0.450). Volumetric BMD and urinary D-pyd levels of FSS and control groups were similar. Mean or median levels of calcium, phosphorus, alkaline phosphatase, parathormone, and osteoprotegerin did not significantly differ between CDGP, FSS, and control groups.Our data suggest that prepubertal boys with CDPG have normal bone turnover. However, their significantly higher urinary D-pyd levels relative to those of FSS and control groups might be an indicator of later development of osteoporosis. Therefore, long-term follow-up studies monitoring bone mineral status of prepubertal boys with CDPG from prepuberty to adulthood are needed to better understand bone metabolism of these patients.

Background/Aims: Congenital hyperinsulinism (CHI) denotes an inappropriate secretion of insulin from pancreatic β-cells in the presence of a low blood glucose level due to various genetic causes. Diazoxide is the first-line medical treatment for CHI. In case of failure, a somatostatin analogue called octreotide is used. A prolonged QT interval is an unusual side effect of octreotide which can be lethal if unrecognized. Case Presentation: We report on a 35-day-old infant who was diagnosed with CHI on the 3rd day of his life and underwent pancreatectomy due to failure of medical treatment at 8 months. His genetic analysis revealed a compound heterozygosity for a novel missense mutation (p.Met115Val) and a nonsense mutation (p.Trp1339X) in the ABCC8 gene. Furthermore, at the 6th month of follow-up, a long QT (0.49 s) was determined by ECG examination, which was normalized following discontinuation of octreotide treatment after pancreatectomy. Thus, the long QT was considered to be secondary to octreotide medication. Conclusion: We recommend ECG monitoring before and during octreotide treatment in order to recognize a prolonged QT interval and to prevent related complications in cases with congenital hyperinsulinemia.

OBJECTIVE To investigate vitamin D status in children with Hashimoto thyroiditis. SUBJECTS AND METHODS The study group consisted of 78 children recently diagnosed as Hashimoto thyroiditis and 74 subjects as the control group. Parameters of calcium metabolism, thyroid function tests, and 25-hydroxyvitamin D [25(OH)D] levels were measured. RESULTS Vitamin D deficiency rate was significantly higher in the Hashimoto group compared with the control subjects (73.1% vs. 17.6%, p < 0.0001). In the Hashimoto group, mean 25(OH)D levels were significantly lower compared with the control group (31.2 +/- 11.5 versus 57.9 +/- 19.7 nmol/L, p < 0.001) and was inversely correlated with the anti-thyroid peroxidase (anti-TPO) levels (r = -0.30, p = 0.007). CONCLUSION The higher vitamin D deficiency rates besides lower vitamin D levels in the Hashimoto group together with the inverse correlation between vitamin D and anti-TPO suggest that vitamin D deficiency may have a role in the autoimmune process in Hashimoto thyroiditis in children.
