Background: GH deficiency (GHD), can either be isolated (IGHD) or part of multiple pituitary hormone deficiency (MPHD), is a pituitary hormone disorder that manifests with short stature.Objective and hypotheses: To evaluate the presenting characteristics, auxological and etiologic factors of GHD in a large cohort from a single tertiary paediatric endocrine centre.Methods: Hospital files of patients followed with GHD deficiency at D...

Background: Euthyroid sick syndrome (ESS), also known as non-thyroidal illness or low T3 syndrome, is defined as low T3, low/normal T4 and inability of rise in TSH due to extrathyroidal diseases. Any condition resulting stress such as infectious diseases, sepsis, metabolic disorders and severe malnutrition can associate to ESS. Patients presented with type 1 diabetes mellitus (T1DM) are usually being screened for other autoimmune diseases inclu...

Background: Mutations in CHD7 cause a rare multi-organ system disorder, CHARGE syndrome (CS). Genital hypoplasia has been described in 60-80% of reported cases because of idiopathic hypogonadotropic hypogonadism (IHH), which is a result of inadequate GnRH secretion in the hypothalamus. Correspondingly, IHH and anosmia are expected in cases with CHD7 mutation. However, due to the phenotypic spectrum of CHD7, mutations have also be...

Introduction: PTEN Hamartoma Tumor Syndrome (PHTS) is a rare disease with dominant inheritance characterized by benign (hamartoma) and malignant tumors (breast, endometrium, thyroid). Mutations in the tumor suppressor gene phosphatase and tensin homologue (PTEN) gene are responsible for the etiology.Objective: In this case report, we present an 11-year-old male who was being monitored due to follicular thyroid cancer, an...

Introduction: Autoimmune polyglandular syndrome type 1 (OPS1) is characterized by chronic mucocutaneous candidiasis, hypoparathyroidism and autoimmune adrenalitis. The mutations in the localized autoimmune regulator gene (AIRE) at 21q22.3 present the etiological cause.Objective: In this case report, two siblings case who were diagnosed with OPS1 with different clinical findings except classic triad were presente...

Introduction: 17β-hydroxysteroid dehydrogenase type 3 (17βHSD3) enzyme deficiency is a rare cause of 46 XY disorder of sexual development. It is inherited autosomal recessively and clinical phenotype is highly heterogeneous and depends on the mutation severity. Conversion of androstenedione to testosterone deteriorates due to lack of enzyme.Objective: In this case report, we present a case who was born en...

Objective: Congenital Hyperinsulinism (CHI) is a clinically, genetically and histologically heterogenous diesease. In recent years substantial developements have been observed in the genetics, imaging techniques and treatment options. We herein present the clinical characteristics, genetics and follow-up of 31 CHI patients from a single paediatric endocrine center with a particular emphasis on the new treatment options.Patients and method: Clinical chara...

Background: Neonatal diabetes mellitus (NDM), either transient (TNDM) or permanent (PNDM), is a rare form of monogenic diabetes, and usually presents in the first 6 months of life.Objective and Hypotheses: To describe the clinical characteristics and molecular genetics of a large Turkish cohort of NDM from a single centre.Method: NDM patients presenting to Diyarbakır Children State Hospital between 2010 and 2013 were prospecti...

Background: Wolfram syndrome (WS or DIDMOAD) is a rare (prevalence of 1/770,000) autosomal recessive multi-systemic neurodegenerative disease, characterized by non-autoimmune diabetes mellitus (DM) and optic atrophy. Additional features include diabetes insipidus (DI), sensorineural deafness, urinary tract abnormalities, ataxia, psychiatric illness, and other endocrine disturbances leading to death in mid-adulthood. This syndrome is caused by recessive mutations in the wolfram...

Background: Recently, the first patients with resistance to thyroid hormone (RTHα) due to inactivating mutations in TRα1 have been identified. These patients are characterized by growth retardation, delayed bone development, mild cognitive defects, delayed motor development and abnormal thyroid function tests.Objective and hypotheses: We hypothesized that the phenotype of a TRα mutation depends on its location, e.g. if it is present only i...
