Different Potent Glucocorticoids, Different Routes of Exposure but The Same Result: Iatrogenic Cushing's syndrome and Adrenal Insufficiency

Güven Ayla

Background: Cushing's syndrome (CS) is very rare in children and the most common cause is the high doses of glucocorticoids (GC) administered. It is well known that application of potent GCs cause iatrogenic CS (ICS) due to suppressing hypothalamo-hypophyseal-adrenal (HPA) axis and later even adrenal insufficiency (AI). Other side effects of GCs are also seen in these patients.Objective: The aim of this study is to r...

An Interesting Etiology in Childhood Central Diabetes Insipidus HIBERNOMA

Ergur Ayca Torel , Aslan Ayla , Canhilal Ece

Introduction: Central Diabetes Insipitus (CDI) results from the inability to secrete ADH secreted by the neurohypophysis system to control water-electrolyte metabolism. In the etiology of CDI many congenital and acquired CNS tumors, infiltrative diseases,infections, autoimmune events, head trauma and idiopathic can be responsible. In this article, a child case with CDI due to intracranial occurence which is very rare in etiology is presented and the approach and follow up are ...

Pubertal timing and characterization in children with congenital hypothyroidism: How important is preschool age anthropometry?

Güven Ayla , Nurcan Cebeci Ayşe

Introduction: The main purpose of the study was to determine whether anthropometric measurements at preschool (PS)-age, in which physiological adiposity rebound is detected, and LT4 dose have an effect on the age of onset of puberty in children with hypothyroidism.Methods: This is an observational and retrospective study.Results: Puberty had begun in 44 girls and 25 boys out of 115...

Idiopathic Infantile Hypercalcemia: Mutations in SLC34A1 and CYP24A1 in Two Siblings and Fathers

Güven Ayla , Konrad Martin , Schlingmann Karl Peter

Background: Both CYP24A1 and SLC34A1 gene mutations are responsible for idiopathic infantile hypercalcemia (IIH). Whereas loss-of-function mutations in CYP24A1 (25-OH-vitamin D-24-hydroxylase) lead to a defect in the inactivation of active 1,25(OH)2-vitamin D3, mutations in SLC34A1 encoding renal sodium-phosphate co-transporter NaPi-IIa lead to primary renal phosphate wasting combined with an inappropri...

A Case of Childhood Type 1 Diabetes Mellitus Who Developed Granuloma Annulare

Oztekin Aynure , Kendirci Havva Nur Peltek , Guney Guven

Introduction and aim: Granuloma Annulare (GA) is a granulomatous dermatitis of unknown etiology with numerous associations, consisting of a single or multiple small lesions (of nodular or papular shape) with annular configuration, usually localized on dorsal surfaces of the feet or hands and over other bony prominences; it is clinically painless and not pruriginous. Granuloma annulare has rarely been reported in childhood, and its association with type 1 diabetes mellitus (T1D...

A Rare Cause of Peripheric Precocious Puberty: Adrenocortical Tumor

Sari Erkan , Atas Erman , Guven Ahmet , Yesilkaya Ediz

Background: Adrenocortical tumor is very rare in the pediatric age group. These tumors may cause peripheric precocious puberty, Cushing’s syndrome or both. It is seen most commonly in children under 5 years of age and fourth decade. p53 mutation and other pathologies that may accompany should be investigated especially in young children.Objective and hypotheses: A 18-month-old boy was brought with pubarche and phallic enlargement, and was noticed 6 ...

Online Survey to Characterise the Burden of Illness in Children with X-Linked Hypophosphatemia

Linglart Agnes , Dvorak-Ewell Melita , Marshall Ayla , Martin Javier San , Skrinar Alison

Background: X-linked Hypophosphatemia (XLH), the most common heritable form of rickets, is a disorder of renal phosphate wasting caused by high circulating levels of fibroblast growth factor 23 (FGF23) that impairs normal phosphate reabsorption in the kidney and production of the active form of vitamin D. Affected children present with hypophosphatemia resulting in rickets, bowing of the legs and short stature. Limited information is available about the disease burden in child...

Background and Objective: Homozygous mutations in the “Centrosomal Protein-19 (CEP19)” gene are extremely rare causes of early-onset severe monogenic obesity. We, herein, report three siblings with CEP19 mutation.Case Presentation and Method: The index case was a 12-years-old female who presented with severe obesity (BMI:62.7kg/m2), metabolic syndrome and diabetic ketoacidosis. Her non-identical twin female s...

The Effect of Polychlorinobiphenyls on Premature Puberty in Girls

Guven Raziye Burcu , Ozen Samim , Gokşen Damla , Korkmaz Ozlem , Darcan Şukran

Introduction: Studies show that onset of puberty in girls is occurring at increasingly younger ages. Environmental endocrine disruptors are implicated in the etiology of early puberty. Polychlorobiphenyls (PCBs) are one of the endocrine disruptor with proven estrogenic effects.Aim: To investigate the effect of PCBs on premature puberty in girls.Materials-Methods: The study group was selected from girls aged 2–8 years with a di...
