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...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

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...

Seven Cases with Williams Beuren Syndrome: Endocrine Evaluation and Long-Term Follow-Up

Guven Ayla

Objectives: Hypercalcaemia, hypothyroidism, and early puberty are the most common endocrine disorders defined in Williams-Beuren syndrome (WBS). Here, endocrine evaluation and long-term follow-up of seven patients with WBS are given.Methods: Data were obtained from patientÂ’s medical records. WBS was diagnosed by demonstration of the deletion on chromosome 7 by using FISH method (7q11.23). OGTT were performed in four patients. Thyroid ultrasonography...
