Introduction: Medulloblastoma is the most common central nervous system tumour in children representing, approximately 20% of childhood brain tumours. Cure can be achieved with surgery, chemotherapy and radiotherapy. However, disease survivors encounter long term endocrine complications including short stature due to growth hormone (GH) deficiency and spinal radiotherapy.Patients and Methods: We aimed to investigate long...

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...

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Introduction and Aim: In this study, we aimed to investigate the admission characteristics, the ratio of permanent/transient hypothyroidism, and the predictors of permanent or transient hypothyroidism at initial evaluation in newborns admitted in 2013 and 2014 from neonatal TSH screening program.Method and Results: During two years period, 985 babies were admitted to our clinic with screening results for evaluation, and ...

Context: Clinical experience is limited regarding the efficacy of different depot Leuprolide acetate (dLA) treatment protocols in girls with central precocious puberty (CPP).Aim: To compare the 3.75 mg/4 weeks versus 11.25 mg/12 weeks ıntramuscular injection of dLA in suppressing gonadotropins and pubertal development.Subjects and Methods: In a prospective study, 92 girls wit...

Context: Intravenous Gonadotropin-Releasing-Hormone (GnRH) stimulation test has a central role in evaluating gonadotropic activation in the diagnosis and monitorization of the treatment in patients with central precocious puberty (CPP). However, this test is invasive, laborious, costly and availability of GnRH preparation is limited in some countries.Objective: To evaluate the utility of the LH level measured 40-minutes ...

Background/aims: Pilocytic astrocytomas (PA) are low-grade neoplasms that affect the precortical visual pathway and are most commonly detected in children and adolescents, representing 2–5% of childhood central nervous system (CNS) tumours. Optic gliomas (OPGs) can occur sporadically, or in association with neurofibromatosis type 1 (NF1). We assessed the prevalence of endocrine dysfunction in children with PA and evaluated outcomes between subgroups of P...

Background: Human peroxisomal fatty acyl CoA oxidase 1, encoded by the ACOX1 gene, catalyzes the first and rate limiting step in the beta oxidation of straight chain fatty acids in the peroxisomes. Biallelic mutations in ACOX1 are associated with pseudo-neonatal adrenoleukodystrophy characterized by severe hypotonia, seizures, psychomotor retardation followed by neuroregression, and death in early childhood. To date, primary adrenal insuffici...

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...

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), ...
