Background: Glucose is the main energy source for the brain’s cells. Glucose transporter 1 (GLUT1), encoded by the SLC2A1 gene, is a membrane protein that plays an essential role in the transport of glucose across the blood-brain barrier. A mutation in GLUT1, so-called GLUT1 deficiency syndrome (GLUT1 DS; OMIM #606777), results in low levels of glucose in the cerebrospinal fluid despite normoglycaemia. GLUT1 deficiency causes a series of symptoms that ma...

Objective: To determine the prevalences of goitre and thyroid nodule, and to analyse the associations among age, gender, anthropometrics and thyroid volume in school children.Materials and method: Schools governed by Ministry of Education in Van province were included into the study. Sonographic evaluations of thyroid glands were performed in children aged 6–17 years, and weight, height, waist circumference, hip circumference, and skinfold thickness...

A 13-year-old patient was admitted due to delayed puberty. Ovary and uterus had not seen in USG and MRI. On physical examination; body weight: 57 kg (79 P), height 157.7 cm (45P), BMI: 22.9 (83P), TA: 120/80 mmHg. The patient was externally in female appearance and there was no puberty development. Labia minora was seen. The urethral and vaginal openings were in the vestibulum and bilateral gonads could not be palpated in the inguinal canal. Mother and father was cousin. Fathe...

Background/Aim: Type 1 diabetes Mellitus (T1DM) often presents with clear clinical signs after a long-term asymptomatic autoimmune process. This long and silent period has been leading to an increase in awareness day by day in order to prevent and predict the development of the disease. Among the well-known genetic and environmental risk factors, close relatives of the index cases constitute a population that is quite suitable for predicting and preventing the...

Objective: The clinical, laboratory and prognostic findings of the patients diagnosed with Kowarski Syndrome (biologically inactive growth hormone) were evaluated between February 2009 and February 2019 in order to contribute to literature.Materals and Methods: 110 cases diagnosed with Kowarski syndrome between February 2009 and February 2019 were evaluated retrospectively. 97 cases continued to work. 92 cases at least one year, 62 cases...

Background: Pituitary resistance to exogenous thyroxine (RETH) refers to persistently elevated serum TSH levels despite high/normal T4 concentrations in levothyroxine-treated patients. The underlying mechanisms and natural history of RETH in children with congenital hypothyroidism (CH) are not well known.Objective: We aimed to describe the possible mechanisms and natural history of RETH in children with CH.<p class="...

Background: Primary ovarian insufficiency (POI), characterized by amenorrhea with elevated gonadotropin concentrations, includes a spectrum ranging from 46, XX gonadal dysgenesis to premature menopause. There is increased evidence that it has a strong genetic basis in its etiology, however, since its rarity and special condition that does not permit the definition of families with this disorder, the molecular diagnosis remains elusive in most of these patients...

Background: Leptin receptor (LEPR) deficiency is a rare genetic disorder that causes severe early-onset obesity. Most children with this condition are obese before the age of one. Leptin and LEPRs are needed for the regulation of appetite and body weight. The most common symptom, present in 96% of patients, is impaired appetite regulation, also known as hyperphagia. Other clinical features include pituitary hormone disorders; such as hypogonadotropic hypogonad...

Polycystic ovary syndrome is the most common endocrinological disease in women of reproductive age. Although it is thought that pathologies such as insulin resistance, chronic low-level inflammation and hyperandrogenism are central theme of the disease, the exact pathophysiology of the disease has not been fully understood. This study’s aim is to reveal the relationship between routine endocrinological and immunological markers related to chronic inflammation, and to inv...

Objective: Thyroid hormone resistance is a rare autosomal dominant disease. In the pathogenesis of this disease mutations have been reported in two types of thyroid hormone receptors, called alpha and beta. Deletions or mutations in cofactors required to demonstrate receptor effect also reported in the beta receptor gene. The symptoms vary according to the cases. Here; a case of thyroid hormone resistance which is noticed by chance and not treated is presented.<p class="ab...
