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: Pathogenic IGFI gene mutations causing childhood growth failure are rare. Only 5 autosomal recessive mutations, one IGFI copy number variant and 2 heterozygous frameshift mutations are reported. Heterozygous missense IGFI mutations have not previously been described.Objectives: To identify and functionally characterise a novel missense IGFI variant in a patient with postnat...

Background: AHDS is a devastating disease caused by defects in the thyroid hormone (TH) transporter MCT8. Endocrine expression is heralded by systemic hyperthyroidism with elevated serum T3, mildly increased TSH and decreased T4. However, the brain is hypothyroid, causing severe psychomotor retardation. Therapeutic attempts with PTU+levothyroxine or the T3-analogue DITPA could normalize TH derangements but without any neurological improvement. ...

Responsiveness to recombinant human growth hormone (rhGH) treatment in Turner syndrome (TS) is highly variable. Previous research has characterised genetic variants associated with rhGH response but these only have a minor impact. The relationship of these genetic variants to the blood transcriptome is unknown. The aim of this analysis was to relate unsupervised baseline blood transcriptome and genetic data from TS patients to their phenotype, karyotype and responsiveness to r...

Background: β-thalassemia major (β-TM) is the most common genetically determined chronic hemolytic anemia. Studies reported that patients with β-thalassemia are zinc deficient due to increased utilization of zinc by oxidative stress, increased urinary zinc excretion and sequestration in the liver.The development of abnormal glucose tolerance in β-TM is associated with alteration in oxidant-antioxidant status. Zinc plays an essen...

Background: Young adults with type 1 diabetes (T1D) are exempt from conscript military service due to risk of severe hypoglycaemia and metabolic compromise. Nevertheless, there are patients who volunteer to military service.Aims and objectives: To evaluate the effect of military service on metabolic control and incidence of acute diabetes complications.Methods: Study design: retrospective, comparative analysis. Data of 145 T1D pati...

Background: In humans GRB10 negatively regulates GH and IGF1 signaling predominantly via altering phosphorylation of PI3K/mTOR/AKT and MEK/ERK pathways which relate to both growth and metabolic function. We have previously shown that Grb10 knockdown in Zebrafish results in overgrowth with an increase in length and head size. However the impact on weight in relation to length has not been assessed.Objective: To develop a model t...

Background: Type 1 diabetes is associated with deficits in skeletal muscle and bone mass and quality. Inhibition of myostatin, a negative regulator of muscle mass, was explored as a therapeutic modality to improve the muscle and bone phenotype associated with insulin-deficient diabetes.Methods: We investigated whether an inhibitory myostatin antibody in streptozotocin (STZ)-induced diabetes in female mice is protective f...

Introduction: The most common cause of elevated TSH is iodine deficiency, and other common causes are drug use, systemic diseases, and underlying genetic conditions.Objective: We aimed to investigate molecular genetic etiology, genotype-phenotype relationships and the follow-up data in cases with elevated TSH initiated on L-thyroxine treatmentMethods: We retrospectively evaluated c...

Objective: Elevated serum alkaline phosphatase (ALP) levels in pediatric patients can result from various etiologies, with transient hyperphosphatasemia, bone pathologies, and hepatic diseases being the most common. This study aimed to elucidate the etiological factors responsible for elevated ALP levels and to evaluate the clinical presentations of transient hyperphosphatasemia in these patients.Materials and Methods: T...
