Background: Assessment of beta-cell function in type 1 diabetes (T1D) has important implications in both clinical and research settings. Studies are limited by the lack of adjustments demonstrating the extent to which puberty influences C-peptide levels. The aim of this study was to evaluate the influence of pubertal stage as well as age and body mass index (BMI) on multiple C-peptide measures at T1D diagnosis.Methods: T...

Aim: To describe the clinical pattern and laboratory characteristics at presentation of a group of children with type 1 diabetes mellitus living in the Northwest region (Trakya) of Turkey.Methods: The clinical and laboratory data of a total of 315 children who presented with newly diagnosed type 1 diabetes mellitus during a 12 year period (2006–2018) were retrospectively analyzed based on hospital records. The data were assessed by gender and age su...

Backround: Short stature (SS) is one of the common disorders referred for investigation of an endocrine disorder. The etiologies of SS vary and are commonly grouped into pathological and nonpathological disorders. Despite standard clinical and laboratory evaluation, a pathological diagnosis is not reached in 50–90% cases.Aim: The aim of this study was to determine the etiologies and decribe the characteristic of short stature patients who were follo...

Background: Gitelmann syndrome, a rare autosomal recessive disorder, is characterised with hypokalemic metabolic alkalosis, hypomagnesemia and hypocalciuria. Mutations in the SLC12A3 gene, which encodes for ‘Thiazid sensitive sodium chloride co-transporter channels’ located at the renal distal convoluted tubules account for the underlying molecular mechanism of Gitelmann syndrome. Although, is less frequent than those seen in ‘Bartter Syndrome’, the exact m...

17 alpha hydroxylase, 17–20 lyase deficiency is an autosomal recessive inherited congenital adrenal hyperplasia type which is due to mutation in CYP17A1 gene and characterized with adrenal and gonadal sex steroid deficiency, delayed puberty in girls, XY sex development disorder in boys and hypergonadotrophic hypogonadism in both gender.Case: 15 year old girl referred to our clinic with vomiting, fatigue and muscle spasms. In her physical examination...

Background: 21-Hydroylase deficiency is the most common cause of congenital adrenal hyperplasia (CAH) and resulted from CYP21 gene mutations. Genotype and phenotype are usually concordant. Homozygous intron 2 splice mutation (IVS2/IVS2) is frequently associated with severe enzyme deficit, and causes classical CAH. Here, we present genotype–phenotype discordant members of two different families with IVS2/IVS2 mutation.Family 1: First child of family ...

Background: Childhood is a dynamic process with continuous growth and development. Growth charts are essential for the assessment of children’s health status. Standards previously established in children aged 6–18 years, according to percentile curves are used in Turkey.Objective and hypotheses: To determine the effect of different environmental factors on growth of children with the same genetic origin. We investigated the parameters of growth...

Background: Hypothyroidism is frequently associated with muscular disorders and sometimes with moderately elevated levels of muscle enzymes. On the other hand, neuromuscular manifestations are rarely the only symptoms/signs present. Kocher–Debré–Semelaigne syndrome is a myopathy of hypothyroidism in childhood characterized by muscular hypertrophy. Rhabdomyolysis due to hypothyroidism is very rare. A very high creatinine kinase level in the range seen with inflam...

Background: Premature pubarche (PP) is known to be a risk factor the development of metabolic syndrome (MS) and hyperandrogenism.Aims: To evaluate if glucose and insulin metabolism, cardiovascular risk factors and cardiovascular risk factors in family (FCVRF) create a risk for insulin resistance (IR) and if PP is a risk factor alone for MS and hyperandrogenism in normal weighted prepubertal PP girls.Methods: Prepubertal and non-obe...

Background: Boys with 21-hydroxylase deficiency (21-OHD) develop testicular adrenal rest tumors (TARTs) at a high percentage. TARTs may lead to testicular structure damage and infertility. Treatment consists of increasing the glucocorticoid dose to suppress ACTH or surgery when necessary.Objective and hypotheses: We present an adolescent with TART who was treated by testicular sparing surgery at the age of 11.Method: A 13 -year-old...
