Background: Hypoparathyroidism (HP) is the most common first endocrinopathy in patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED or APS1), an autosomal recessive condition caused by mutations in the AIRE gene. Treatment of HP has not changed over the decades and parathyroid hormone is used only rarely.Aim: To describe clinical characteristics and course of HP in a cohort of patients with APECED and eva...

Introduction: Pseudo-precocious puberty may be triggered by either endogenous or exogenous sex steroids. Accidental ingestion of contraceptives, anabolic steroids or life style products containing sex steroids as well as transdermal transmission of topical sex steroids may cause early onset of secondary sexual development.Objective: To report the clinical course of incidental contamination with topical sex steroids in ch...

Background: Congenital hyperinsulinism (CHI) is the most common cause of the persistent hypoglycemia in children. Mutations in KCNJ11 and ABCC8 genes coding potassium channel subunits are responsible for a significant proportion of CHI patients. The type of mutation correlates with the type of B-cell hyperplasia (focal or diffuse), and determinates further diagnostics, treatment and prognosis of disorder.Aims and objectives: The aim of ...

Background/Aim: Parents wanting to predict adult height (AH) often resort to the old practice of doubling a boy’s height at age 2 years or a girl’s height at 18 months. We coined this the ’Grandma prediction’ (GMP1). It provides predictions with mean absolute error (MAE) 5.9 and 5.2, standard deviations of residuals (sdRES) 4.1 and 3.6, and Pearson correlation r=0.68 and 0.67 for boys and girls, respectively. The recent sophist...

Background:Calcium-sensing receptors (CaSR) located on parathyroid glands and kidneys act to regulate serum calcium levels. Inherited hypocalciuric hypercalcaemia and autosomal dominant hypercalciuric hypocalcaemia are due to inactivating and activating CaSR mutations respectively. We present the immediate and medium term postoperative clinical course of the first paediatric patient with hypercalciuric hypocalcaemia managed with a simultaneous parathyroid and ...

Background/Aim: The trade-off theory claims that a resource (calorie) stored in adipose tissue cannot be used for longitudinal growth, and a calorie used for growth will not be stored as fat.Methods: Out of 2339 children with longitudinal heights and weights (birth to adulthood) from the GrowUp1990 Gothenburg cohort, 1993 (996 girls) were analyzed. For everyone we calculated Energy Trade-Off Score: ETOS = at early adulth...

Introduction: Granulosa cell tumors (GSTs) of ovary are very rare, usually large gonadic neoplasms arising from the mesenchyme and sex cords. The main clinical appearance of the juvenile GCTs is represented of signs of excessive estrogen (Precocious puberty - 75% of cases) or testosterone secretion (rare).Aim: To present the different clinical presentation and outcome in a case series of a rare tumor patients.<p clas...

Introduction: Deficiency of 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3) enzyme encoded by HSD17B3 is a rare cause of disorders of sex development (DSD). The phenotype associated with 17β-HSD3 deficiency in 46, XY individuals is variable, ranging from predominantly male external genitalia with micropenis and hypospadias to completely female external genitalia. The diagnosis and management of this enzymatic defect is very challenging.<p class="abste...

Background: Jacobsen syndrome is a rare genetic condition caused by partial deletion of the long arm of chromosome 11 associated with delayed development, distinctive facial features, bleeding disorder, skeletal abnormalities and endocrine disorders.Case report: We report a rare case of Jacobsen syndrome in 4 year old boy addressed for short stature. Born at term (36 W) with low birth weight (1780 g) and delayed development, his height at presentation wa...

Background: Mixed gonadal dysgenesis (MGD) is a disorder of sex development associated with a numerical sex chromosome abnormality. Reported genital phenotypes range from female external genitalia or mild clitoromegaly through all stages of ambiguous genitalia to hypospadias or a normal penis, depending on the proportion of monosomic cells.Case presentation: 18 years old girl, with a history of hypertension, ventricular septal defect and obesity presente...
