Background: Hepatocyte nuclear factor 1β (HNF1β) is a critical transcription factor that regulates the development of the kidneys, pancreas, liver and genital tract. Patients with deletions and mutations in the HNF1 β gene present with renal and extrarenal manifestations. The most important extrarenal finding is diabetes, also known as MODY5. Although it is generally diagnosed with hyperglycemia, diabetic ketoacidosis is rarely seen.<p class...

Aim: This study aims to investigate the presentation characteristics, follow-up, and treatment modalities in children and adolescents diagnosed with Type 2 Diabetes (T2D).Materials and Methods: This retrospective chart review includes 50 patients aged 4-20 years diagnosed with T2D between February 2013 and October 2023 according to American Diabetes Association (ADA) criteria in pediatric endocrinology clinic of a univer...

Post-OGTT hypoglycemia is common in Cystic Fibrosis(CF). The aim of the study is to determine of the role of glucagon in the pathogenesis of hypoglycemia in CF patients. A 3-hour-OGTT was performed fifty-three subjects (44CF,9 age-matched controls). Sixteen (36.4%) subjects had normal glucose tolerance (NGT), 13 (29.5%) had isolated hypoglycemia (IsoHypo), 8 (18.2%) had hypoglycemia with abnormal glucose intolerance (Hypo+AGT), 5 (11.4%) had AGT and 2 (4.5%) had CFRD. After AG...

A worldwide increase in pediatric thyroid cancers incidence over the years has been observed. Although pediatric thyroid cancers tend to have a more aggressive course compared to adults, the survival rate is better. In this study, we aimed to examine the demographic, clinical, pathological, and laboratory characteristics, prognostic and risk factors of children with thyroid cancer.Methods: We retrospectively analyzed 39 children with thy...

Objective: Congenital Hyperinsulinism (CHI) is a clinically, genetically and histologically heterogenous diesease. In recent years substantial developements have been observed in the genetics, imaging techniques and treatment options. We herein present the clinical characteristics, genetics and follow-up of 31 CHI patients from a single paediatric endocrine center with a particular emphasis on the new treatment options.Patients and method: Clinical chara...

Background: Osteogenesis imperfecta (OI) is a heterogeneous group of brittle bone disease mostly caused by quantative or qualitative defects in type I collagen. In most populations, more than 90% of the patients with OI have dominant mutations in COL1A1 or COL1A2 genes (AD-OI). Less than 10% of the cases have recessive inheritance (AR-OI). Currently 12 genes have been identified as a cause of AR-OI.Objective and hypotheses: We assumed h...

Background: Short stature (SS) is one of the most frequent reasons for referral to pediatric endocrinology clinics.Objective and hypotheses: We aimed to analyse the etiological factors of SS, in patients of our clinic, who are referred from general paediatrics with high likelihood of endocrinological problems after primary screening.Method: 1519 patients (693F) with height <3% were included. Clinical, anthropometric, radiologic...

Background: Hereditary vitamin D-resistant rickets (HVDRR) is a rare disease caused by mutations in vitamin d receptor (VDR). Patients with HVDRR are usually treated with intravenous calcium (i.v.-Ca) therapy via a central catheter. However, central catheter-related complications can cause important morbidity. In this report, we described four patients with HVDRR from different families. In three of these cases we used a novel therapeutic regime of intermittent IV-Ca ...

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...

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...
