Gonadotropin-releasing hormone (GnRH) is the central regulator of gonadotropins, which stimulate gonadal function. Hypothalamic neurons that produce kisspeptin and neurokinin B stimulate GnRH release. Inactivating mutations in the genes encoding the human kisspeptin receptor (KISS1R, formerly called GPR54), neurokinin B (TAC3), and the neurokinin B receptor(More)
OBJECTIVE Normosmic idiopathic hypogonadotropic hypogonadism (nIHH) is characterized by failure of initiation or maintenance of puberty due to insufficient gonadotropin release, which is not associated with anosmia/hyposmia. The objective of this study was to determine the distribution of causative mutations in a hereditary form of nIHH. METHODS In this(More)
Iron deficiency anemia (IDA) remains the most prevalent nutritional deficiency in infants worldwide. The purpose of this study was to determine the efficacy of daily and weekly iron supplementation for 3 months to improve the iron status in 4-month-old, exclusively breast-fed healthy infants. Infants 4 months of age were eligible for the open, randomized(More)
WISP3 is a member of the CCN (for CTGF, CYR61, and NOV) gene family, which encodes cysteine-rich secreted proteins with roles in cell growth and differentiation. Mutations in the WISP3 gene are associated with the autosomal recessive skeletal disorder, also known as progressive pseudorheumatoid arthropathy of childhood (PPAC). We diagnosed three siblings(More)
Growth Hormone (GH) is a 22 kDa protein that has effects on growth and glucose and fat metabolisms. These effects are initiated by binding of growth hormone (GH) to growth hormone receptors (GHR) expressed in target cells. Mutations or deletions in the growth hormone receptor cause an autosomal disorder called Laron-type dwarfism (LS) characterized by high(More)
BACKGROUND The aim of this study was to compare the chromium levels of plasma (PCL), erythrocyte (ECL) and urine (UCL) in type 1 diabetics and healthy subjects and to review the relation between metabolic parameters. METHODS We evaluated 165 subjects who were: newly diagnosed type 1 diabetics (group 1 [n= 29]); previously diagnosed type 1 diabetics (group(More)
OBJECTIVE The aim of this study was to elucidate the role of adiponectin, leptin, TNF-α and IL-6 on the early detection of the microvascular complications of type I diabetes. MATERIALS AND METHODS A total of 88 children were included in the study. There were 60 type I diabetic patients and 28 healthy control children. RESULTS The gender, age, weight,(More)
We aimed to investigate the effects of age onset of diabetes, glycemic control and frequency of hypoglycemia on neurocognitive functions in type I diabetic children. Sixty type I diabetic children with diagnosis before (Group 1) or after (Group 2) five years of age and 40 healthy children were tested. Wechsler Intelligence Scale for Children Revised(More)
Visceral leishmaniasis results in hematological problems such as cytopenias and coagulopathies. This disorder also has morphological effects on the bone marrow. Dyserythropoiesis is one of the most prominent seen with changes like multilobed nuclear cells and the appearance of bridges between nuclei and cytoplasms. Approximately half of the children with(More)
BACKGROUND Thanatophoric dysplasia (TD) is the most lethal and most severe type of dysplasia. It has distinct features, the most important of which is short tubular bones and short ribs with platyspondyly, allowing a precise radiologic and prenatal ultrasonographic diagnosis. It has been reported to be caused by mutations in the FGFR3 gene, but exactly how(More)
