İdiyopatik Boy Kısalığı

İdiyopatik boy kısalığı İBK , boyun - 2 standart deviasyon skorunun SDS altında olması ve altta yatan herhangi bir hastalığın olmamasıdır. Ailevi boy kısalığı ve ailevi olma- yan boy kısalığı olarak iki gruba ayrılır. İBK patofizyoloji- si çok geniş ve heterojendir. Boy kısalığı nedenleri açısın- dan uygun değerlendirmeler yapılıp, İBK tanısı ile takip edilmeye başlanan çocuklar için çok yönlü tedavi protokol- leri denenmekte ve olumlu sonuçlar alınabilmektedir

Idiopathic Short Stature

Idiopathic short stature ISS refers to the condition where the height is below-2 standard deviation score SDS wit- hout any underlying disease. It may be divided in two gro- ups as familial short stature and non-familial short stature. The pathophysiology of ISS is multifaceted and very hete- rogeneous. Following appropriate evaluations, children with ISS can be treated with a multifaceted treatment pro- tocol and satisfactory results can be achieved
