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: Laron syndrome (LS) is a disorder of primary growth hormone (GH) resistance caused by genetic defects in GH and insulin-like growth factor 1 (IGF-1) axis. Here, we present the variable clinical spectrum in two sibling cases of Iraqi Arab origin with GH receptor (GHR) mutation.CASES: Two siblings referred to our clinic with the chief complaint of short stature. They had been born with a normal weight at term.Their parents were...

Type 1 Diabetes (T1DM) is a chronic metabolic disease characterized by hyperglycemia due to absolute insulin deficiency as a result of autoimmune damage of pancreatic β cells. In its treatment, insulin, medical nutrition therapy and exercise is recommended. Although it is known that exercise contributes to disease control, the mechanism of these effects has not been fully clarified. It is thought that myokines such as irisin and sestrin, can be effective by secreting with...

Introduction: Graves’ Disease (GD) is autoimmune hyperthyroidism occurring mostly in adolescent girls. The main pathogenic role of the disease is attributed to TSH receptor antibodies (TRAb), which stimulate the thyroid gland to increase the production of the most active thyroid hormone- triiodothyronine (T3). High levels of TRAb and a large goitre size are commonly known as poor prognostic factors for the disease and are used to predict relapse.<p c...

Background: Despite different genetic backgrounds, Noonan syndrome (NS) shares similar phenotype features to Turner syndromes (TS) such as short stature, webbed neck and congenital heart defects. The primary cause of short stature in Turner syndrome and Noonan syndrome is GH resistance [1]. Recombinant human growth hormone (rhGH) is being used to promote linear growth in short children with Noonan syndrome. However, its efficacy is still controversial.<p c...

Purpose: The aim of the present study was to determine the efficiency of three different predictive models [Bayley-Pinneau (BP), Roche-Wainer-Thissen (RWT), and Tanner-Whitehouse 2 (TW2)] by comparing their predictions with near-adult height (NAH) data of girls who received gonadotropin-releasing hormone agonist (GnRHa) therapy.Methods: Clinical findings were retrospectively analyzed. Bone age (BA) was determined by thre...

Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

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: Menarche is the endpoint of a complex sequence of maturational events but is the unique marker of female puberty. Timing of menarche is a strongly heritable trait. However, secular trends suggest that lifestyle and/or environmental factors are important.Objective: To assess the trend in age at menarche (AAM) in Istanbul over the last 12 years, and compare the patterns according to socioeconomic status (SES), ...
