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...

Background: β-hCG secreting germ-cell tumors (β-hCG-ST) are rare causes of Peripheral precocious puberty (PPP) in boys and usually located in intracranial region. Liver, retroperitoneum, testis and mediastinal cavity are the other localizations reflecting embryonic germ cell sites.Objective and hypotheses: We present a patient with PPP due to elevated β-hCG levels, but extensive efforts to find the source of elevated β-hCG was unrevea...

Background: Diagnosis of GH deficiency (GHD) is a complicated issue especially in isolated GH deficiency. Auxological evaluation, IGFI, IGFBP3 levels and GH response to provocative testing are all considered in the diagnosis. However, cut-off values for GH levels at stimulation tests are controversial. We aimed to evaluate the response to rhGH treatment in patients with different GH peak levels in stimulation test.Objective: We aimed to evaluate the resp...

Itroduction: Thiamine responsive anemia (TRMA) known as Rogers syndrome; is an early-onset, autosomal recessive disorder characterized by diabetes mellitus, megaloblastic anemia and sensorineural deafness. Diabetes in this condition is well described in infancy but has only very rarely been reported in association with neonatal diabetes.Case: 3-months old male patient with neonatal diabetes was admitted to our outpatient clinic because of uncontrolled hy...

Background: Estimation of the child’s genetic height potential (target height) is an important tool in evaluating growth disorders. Midparental height (MPH) calculated as (Mothers height+Fathers height)/2±6.5 cm), used for this purpose, represents the child’s expected height based on parental heights.Objective and hypotheses: To evaluate the classical MPH calculations for our population and to explore the optimal MPH model using different ...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...
