Objective: Most recent evidence from conducted in human and animal studies suggests that vitamin D has a potential role in the physiology of reproductive function in both genders. We investigate the role of vitamin D in male and female gonadal function at mini-puberty period with particular emphasis on production of sex steroids and gonadal peptide hormones. Additionaly, this study evaluated serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradio...

Background: Hypothalamic-pituitary-gonadal axis is activated during the first 6 months of life, called as mini-puberty in which reproductive hormone levels may reach to adult levels. Although, our understanding of the pathophysiology of sex steroids interaction with growth in puberty is increasing, very little is known about the relationship between sex steroids and growth at this period of life.Material and Methods: 142...

Aim: To evaluate thyroid function tests and affecting factors in twin and triplet newborns.Method: 655 newborns from 320 multiple gestations (305 twins/15 triplets) were evaluated retrospectively with respect to thyroid function tests (FT4, TSH). The effects of birth order, birth weight SDS, gestational age, maternal thyroid disease, gestational diabetes, assisted reproduction, dopamine were analysed.Results: Gestational age was 25...

Introduction: Short stature is a common manifestation of Noonan syndrome (NS). GH deficiency, GH insensitivity, and neurosecretory dysfunction have been reported in the literature. The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...

Background: Adrenocortical carcinoma (ADCC) is a rare cancer in children and differs significantly in epidemiology, clinical characteristics, and biologic features from their counterparts in adults. Germline mutations of the TP53 tumor suppressor gene are associated with cancer predisposition in families with the Li-Fraumeni syndrome.Aim: To report a young girl with family a history of ADCC who presented with severe virilisation secondary to ADC...

Background: Adrenal insufficiency is an important and potentially life-threatening condition, and it is also known as a rare cause of hypercalcaemia.Objective and hypotheses: Resistant hypercalcemia may be associated with hypocortisolism.Method: A 18-day-old male infant was born at 36 weeks by emergency cesarean section for fetal distress and intrauterine growth retardation. He was referred to paediatric endocrinology because of th...

Background: Ovotesticular disorder of sexual development (DSD is a rare form of DSD in which both testicular and ovarian tissues are present in the same individual either in a single gonad (ovotestis) or in opposite gonads with a testis and an ovary on each side.Objective and hypotheses: To discuss rare cases of ovotesticular DSD and one of the novel findings of these cases.Methods and patients: Case 1 is the first child of unrelat...

Congenital rubella infection is a transplacental infection that can cause intrauterine growth retardation, cataract, patent ductus arteriosus, hearing loss, microcephaly, thrombocytopenia and severe fetal injury. It has been shown that type 1 diabetes mellitus develops in 12–20% of patients with congenital rubella infection and disorder in oral glucose tolerance test is observed in 40%. A 13-year-old male patient presented with complaints of new-onset polydipsia, urinatio...

Background and Objectives: Recent studies demonstrated that a 1-hour post-load plasma glucose (1-h PG) value of ≥155 mg/dL during an oral glucose tolerance test (OGTT) is a new risk factor for predicting atherosclerosis. Herein, we evaluated whether individuals with normal glucose tolerance (NGT), whose 1-h PG is ≥155mg/dl, or with impaired glucose tolerance (IGT) have an increased carotid intima–media thickness (CIMT), as compared with NGT in...

Introduction: The molecular mechanisms underlying insulin resistance (IR) is complex and has not been fully elucidated yet. The experimental studies point out the role of liver-derived proteins, called hepatokines.Aims: To compare metabolic parameters and hepatokines levels in obese adolescents and healthy controls and to assess the effect of metformin therapy on plasma hepatokines levels in obese, insulin-resistant adol...
