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: Subclinical hypothyroidism (SH) is defined as an elevated serum concentration of TSH when serum free thyroxine (fT4) concentration is within its reference range. Impaired myocardial contractility in overt hypothyroidism and left ventricular (LV) diastolic dysfunction in adults with SH as well as beneficial effects of thyroid hormone replacement on systolic and diastolic functions in adults with SH has been documented, however the presence of similar alte...

Introduction: Ceratonia siliqua L. (CS) is from the legumes (Fabaceae) family, and different forms such as carob extract and flour are preferred by parents because it is a natural sweetener and a source of vegetable carbohydrates. CS is rich in polyphenols and flavonoids. When we questioned histories of the cases of early puberty and puberty variants who applied to our clinic, we noticed long-term and regular use in some cases. We planned to experimen...

Objectives: Thiamine responsive megaloblastic anemia syndrome (TRMA) is characterized by the clinical triad of megaloblastic anemia, non-immune diabetes mellitus and sensorineural deafness. It is a very rare autosomal recessive disease with an increased frequency in consanguineous marriages and isolated communities. The syndrome is due to intracellular thiamine deficiency which is the result of a defective high affinity low performance thiamine transporter pro...

Background: It has already been documented that selenium treatment has beneficial effects in adult patients with autoimmune thyroiditis, especially in those with a higher titer of antibodies and increased inflammatory disease activity.Objective and hypotheses: To investigate whether daily supplementation of organic selenium at a high dose (200 μg in the form of L-selenomethionine) has any effect on the titer of thyroid autoantibodies.<p class="a...

Body Mass Index (BMI) has a high association with body fat percentage and direct association with a higher degree of comorbidities. Categorizing patients only by the degree of obesity, as has been done over time, restricts the possibility of detecting and giving timely treatment to other aspects. The Edmonton Obesity Staging System for Pediatrics (EOSS-P) has been proposed as a tool to categorize obesity not only by BMI, but also by assessing metabolic complications, functiona...

The Silver-Russel syndrome (SRS) is characterized by an intrauterine growth retardation accompanied by postnatal growth deficiency. Affected individuals typically have proportionately short statue, finger deformities as well as typical facial features. About 10% of individuals with SRS have maternal uniparental disomy for chromosome 7 (UPD7) and 35%–50% showed hypomethylation of the parental imprinting center region 1 (ICR1) of chromosome 11p15.5. In the recent past also ...

Objective: To determine the prevalence of congenital hypothyroidism (CH) in children with dry bloodspot TSH (b-TSH) between 5 and 10 mIU/l in neonatal screening and evaluate their thyroid function evolution.Methods: Retrospective study of thyroid function in children born from 2003 to 2010 with b-TSH between 5 and 10 mIU/l who were put on treatment in the first two years of life due to serum TSH≥10 mIU/l. The prevalence of CH ...

Background: Pubertal gynaecomastia is thought to be a clinical sign of an oestrogen-androgen imbalance, affecting up to 60% of boys. In most cases no underlying endocrinopathy can be identified. In boys, Anti-müllerian hormone (AMH) is produced by immature Sertoli cells and circulating level decreases as testosterone increases during pubertal maturation. In a previous cross sectional study we found significant lower levels of AMH in boys with pubertal gynaecomastia (Mieri...

Background: Consultations for infantile hypercalcaemia have increased at Sydney Children’s Hospital since guidelines for vitamin D3 supplementation during pregnancy were introduced in 2006. Recent nationwide shortages of low-calcium formula (LCF) suggest this problem may be widespread.Aim: To determine if infantile hypercalcaemia is occurring more commonly, identify potential aetiologies and clinical significance.Me...
