Introduction: The COVID-19 pandemic led to regional lockdowns and restrictions associated with changes in lifestyle and quality of life (QoL) thus potentially burdening metabolic control in Diabetes Mellitus (DM). We examined whether the stages of restrictions lead to changes in QoL and metabolic control in children with DM.Methods: Starting in April 2020, this monocentric prospective longitudinal cohort study included c...

Background: Intrathyroidal ectopic thymus (IET), a benign lesion due to aberrant thymic migration during embryogenesis, is often discovered incidentally. Most of the reports in the literature describe individual cases or small series. We aimed to present the ultrasound (US) features, diagnostic methods, and follow-up of IET in children and adolescents.Methods: We searched our database of patients under 18 years old with ...

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...

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: Obesity and its complications affecting many organ systems have been documented. Nevertheless, study conducted on the ophthalmological effects of obesity are scarce. The aim of the present study was to evaluate the changes in the ophthalmological parameters in obese children in comparison to their healthy counterparts.Material and methods: Study included 61 obese and 35 age-sex matched controls. Obesity was defined as body mass index- standard...

Background and objective: The first and rate-limiting step of steroidogenesis is the conversion of cholesterol to pregnanolone which is catalyzed by the P450scc side chain cleavage enzyme (encoded by CYP11A1 gene-SCC). Homozygous recessive mutations of the CYP11A1 gene cause a global steroid hormone deficiency thereby disorders of sexual development in 46, XY individuals with a variable phenotype depending on the mutation characteristics. About 60 cases of SCC...

Background: Hereditary hypophosphatemic rickets with hypercalciuria(HHRH; OMIM: 241530) is a rare autosomal recessive disorder,which is the result of loss-of-function mutations in the sodium-phosphate-cotransporter NPT2c.This disorder is characterized by renal phosphate(Pi) wasting,hypercalciuria,increased 1,25 (OH)2-D levels and decreased parathormone(PTH) levels.Here we report the clinical features of two siblings with HHRH,confirmed with molecula...

Background: In several studies it has been shown that BMI influences the timing of puberty, mostly in girls, but has not been a consistent finding in boys.Objective and hypotheses: To investigate the association between BMI and timing of pubertal onset in a population based sample of Turkish boys.Method: Data on growth and pubertal development were collected by biannual visits to six primary and secondary level schools in Istanbul ...

Background: Precocious puberty has a complex and polygenic etiology. To describe genetic factors affecting onset and regulation of puberty and pathophysiology of precocious puberty, further studies are needed. Although, it is reported that ACTH receptor MC4R has impact on premature adrenarche, MC2R is expressed in the adrenal cortex and has a major role on the control of hypothalamo-pituitary-adrenal cortex. Melanocortin signaling system is reported to have l...
