Background: Sickle cell anemia (SCA) leads to chronic end organ damage including the thyroid gland. This is postulated to be due to recurrent hemolysis leading to iron overload, vaso-occlusive crises, micro-vasculature obstruction due to red cell entrapment and frequent transfusions. Some studies have demonstrated a relationship between hypothyroidism and SCA with a prevalence of 6% in children and adolescents. Hypothyroidism may affect brain and physical deve...

Background: The association of GH deficiency (GHD) with central precocious puberty (CPP) has been reported in individuals with central nervous system (CNS) abnormalities, congenital or acquired. Co-existence of GHD and CPP has been rarely reported, always as an isolated, sporadic disorder.Objective and hypotheses: To present the familial occurrence of combined GHD and CPP.Method: GH was measured post L DOPA, glucagon and GHRH and g...

Background: Since the initiation of neonatal screening-programs for congenital hypothyroidism (CH) in the 1970’s, an increase in the incidence of CH has been observed. This change has been attributed to the gradual use of lower TSH cut-offs that lead to the detection of milder cases of CH. Based on currently used screening cut-offs, CH occurs in approximately 1:2 000 to 1:4 000 newborns, varying by geographic location and ethnicity. A female predominance, approaching a 2:...

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...

The insulin-like growth factor (IGF) system is fundamental for physiological processes such as growth and metabolism. In addition, in the brain it regulates glucose metabolism and neuroprotection. The IGF axis can be altered by nutritional status, but little is known regarding the effects of specific dietary components on this system.Our aim was to examine how high-fat diet (HFD) and low-fat/high sucrose diet (LFHSD) intake affect the central and circula...

The most common hyperthyroidism in children is Graves' disease. The other rare cause of hyperthyroidism is activating mutation in receptor TSHR in thyroid gland.We would like to introduce a case of familial hyperthyroidism with a novel mutation M453V in the TSHR in three membersActually 11-year-old boy is a patient in outpatient clinic for first days after birth. During gestation his mother was treated with thyreostatic drugs b...

Introduction-Purpose: In addition to chromosomal abnormalities, a number of genes have been implicated as causes of Disorders of Sexual Development (DSD). The NR5A1 (SF-1) gene expresses a transcription factor that plays a role in steroidogenesis by controlling multiple stages of adrenal and gonadal development, and its mutations have been reported in cases of DSD.Case presentation: A 152/12-year-old teenager ...

Background: Fibroblast growth factor 21 (FGF-21) is a complex molecule involved in lipid and glucose metabolism. FGF-21 shares biochemical pathways and sites of action with thyroid hormones. Current data correlate FGF-21 levels to thyroid function. The aim of the present study was to investigate possible associations among FGF-21 levels, resting metabolic rate (RMR), lipidemic profile and L-thyroxin replacement therapy treatment in children and adolescents wit...

Background&: Arrhythmias associated with hyperthyroidism are mainly tachyarrhythmias, such as sinus tachycardia and atrial fibrillation. In comparison, hypothyroidism shows several electrocardiographic changes, including sinus bradycardia, low amplitude QRS complexes, QT interval prolongation. There are few reports of bradyarrhythmia with hyperthyroidism, and it remains unclear.Case: The patient is a 13-year-old girl with Down's syndrome. She underw...

Background: Several bone metabolic pathways seem to be disrupted in patients with type 1 diabetes mellitus (T1DM), leading to reduced bone mass.Objective and hypotheses: Our aim was to study bone metabolism markers in children and adolescents with T1DM and their correlation with bone mineral density (BMD).Method: We evaluated 40 patients (mean±S.D. age 13.04±3.53 years, mean±S.D. T1DM du...
