Background/Aim: Diabetes with extra-pancreatic features in children can have a monogenic aetiology. Single gene testing is undertaken when children present with the characteristic clinical features suggestive of the underlying aetiology. We aim to assess the utility of comprehensive genetic testing for all monogenic diabetes genes in children with diabetes and any non-autoimmune extra-pancreatic features from a population with a high rate of consanguinity.<p class="abstext...

Background: Primary adrenal insufficiency other than congenital adrenal hyperplasia (non-CAH PAI) is very uncommon in children but associated with a variety of molecular defects. Biosynthesis of adrenocortical hormones is reduced although the relation of steroid profiles with underlying molecular etiology is not yet studied.Objective: Investigation of clinical and steroid hormone profiles of a multicenter cohort of child...

Background: Aromatase inhibitors (AIs) have been suggested to slow down estrogen-dependent skeletal maturation in pubertal boys with short stature. In the literature, few studies evaluate the efficacy and safety of AIs in boys with growth hormone deficiency (GHD). Objective: To evaluate the auxologic effects and short-term laboratory profiles of combined AI and rhGH therapy in adolescent males with GHD.Subjects and Methods:</stro...

Background: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires accurate diagnosis and urgent treatment. Congenital adrenal hyperplasia is the most common cause of PAI in children. Non-CAH causes of PAI are relatively rare. Although several molecular causes have been found, it is emerging that considerable overlap in the clinical and biochemical features of these conditions exists.Objective and hypotheses: We inv...

Aim: Hypophosphatemic rickets (HR) is a rare renal phosphate wasting disorder commonly related to X-linked form, caused by PHEX mutations and it treatment and follow-up is challenging due to imperfect treatment options. Here we presented nationwide data on HR with initial and follow-up data on the patients presented to the pediatric endocrinology clinics before the age of 18 years.Results: From 24 centers, 158 patients (93 male/65 female) were i...

Introduction and Aim: Pubertal gynecomastia is the transient proliferation of glandular tissue in breasts of men without any endocrin pathology. Relatively higher levels of estrogen than plasma testosteron levels and imbalance between tissue estrogen and testosteron levels are considered to be important in pathogenesis. In this study it is aimed to determine the clinical and laboratory properties of our patients who were diagnosed as pubertal gynecomastia and compare with heal...
