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: The variable presence of adrenal insufficiency (AI) due to hypocortisolemia (HC) in patients with thalassemia is well established; however, the prevalence of adrenocortical hypofunction (ACH) in the zona glomerulosa and zona reticularis of the adrenal cortex is unknown.Objective and hypotheses: To establish the prevalence of ACH, we examined the cortisol response to 1 μg- and 250 μg- ACTH tests, plasma aldosterone (A)/plasma renin a...

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: Data on the epidemiology of type 1 diabetes among children in Turkey are limited.Objective and hypotheses: The aim of this study was to report, for the first time, the incidence and prevalence of childhood type 1 diabetes in Turkey using a nationwide registry.Method: Information on birth date, city of birth, diagnosis date and gender of all type 1 diabetes patients aged less than 18 years were obtained from the Turkish ...

Background: Congenital hyperinsulinism (CHI), is the most common cause of severe hypoglycaemia in neonates and infants. The cornerstone of medical therapy is diazoxide. Octreotide, a somatostatin analogue, is the second therapeutic option in diazoxide unresponsive cases. However, due to its short half-life and requirement of multiple daily doses, lack of compliance may cause recurring hypoglycaemia and related neurological deficits, particularly for the family with low socioec...

Background: Graves disease is the most common cause of hyperthyroidism in children. The frequency of the disease increases with age, peaking during adolescence.Thyroid storm is a rare but critical, ilness that can lead to multiorgan failure and carries a high death rate. Antithyroid drugs are usually recommended as the initial treatment and are generally well tolerated. Although current treatment options include radioactive iodine, but long term complications of thyroid irradi...

Context: Type 1A pseudohypoparathyroidism (PHP-1A) is characterized by target organ resistance to PTH and Albright’s hereditary osteodystrophy (AHO). Basal ganglia calcifications and subcutaneous ossifications can be seen in PHP-1A. Acetazolamide, a carbonic anhydrase inhibitor, causes metabolic acidosis by increasing bicarbonate excretion from the proximal renal tubule thereby diminish precipitation of calcium and phosphorus. Acetazolamide had been used ...

Background: RASopathies are a group of diseases with common clinical features that occur as a result of pathogenic variants in genes encoding components of the RAS/MAPK pathway. The aim of this study was to evaluate the clinical and molecular features of RASopathy cases in our pediatric endocrinology unit.Subjects and Methods: The clinical and molecular data of 42 patients (18 girls) from 39 families were evaluated, retr...

Purpose: We aimed to determine the frequency and distribution of intracranial pathologies in patients over 8 years of age by evaluating MRI images of patients diagnosed with early puberty-rapidly progressive.Materials and Methods: The study comprised 118 female patients diagnosed with precocious puberty (PP) and rapidly progressive early puberty (RPEP). The onset of puberty in girls before the age of 8 years is defined a...
