Objective: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population-specific growth charts for TS. Considering national and ethnic differences, we undertook this multicenter collaborative study to construct growth charts and reference values for height, weight and body mass index (BMI) from 3 years of age to adulthood for spontaneous growth of Turkish girls with TS.Methods: Cross-sectional height and weight data of 842 patients with TS, younger than 18 years of age and before starting any therapy, were evaluated.Results: The data were processed to calculate the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for defined ages and to construct growth curves for height-for-age, weight-for-age and BMI-for-age of girls with TS. The growth pattern of TS girls in this series resembled the growth pattern of TS girls in other reports, but there were differences in height between our series and the others.Conclusion: This study provides disease-specific growth charts for Turkish girls with TS. These disease-specific national growth charts will serve to improve the evaluation of growth and its management with growth-promoting therapeutic agents in TS patients.
Infantile systemic hyalinosis with early thyroid dysfunction
(Walter De Gruyter Gmbh, 2007-07) Pirgon, Özgür; Atabek, Mehmet Emre; Esen, Hasan H.; Cangül, Hakan; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Genetik Anabilim Dalı.; 8911611600
Infantile systemic hyalinosis is an autosomal recessive disorder characterized by diffuse hyaline deposits in the skin, gastrointestinal tract, muscles and glands. The molecular basis of infantile systemic hyalinosis is unknown. The main pathological feature is widespread hyalinosis of many tissues and organs. We present an 18 month-old girl with infantile systemic hyalinosis and hypothyroidism. Newly diagnosed children with infantile systemic hyalinosis should have thyroid studies as a routine part of diagnostic work-up.
Pediatride hiperparatiroidizm
(Uludağ Üniversitesi, 2007) Pirgon, Özgür; Atabek, Mehmet Emre
Paratiroid hormon; kalsiyum ve fosfor dengesinde kemik, gastrointestinal sistem ve böbrekler üzerinde etkisiyle temel rol oynamaktadır. Patolojik durumlarda paratiroid hormonun aşırı artışı kemik sağlığı üzerinde olumsuz etkiler göstermektedir. Paratiroid hormonun birçok etkisinin anlaşılması iskelette anabolik ajan olarak tedavide kullanılmasına imkan sağlamıştır. Bu derlemede paratiroid hormonun sekresyonu ve etkisi özetlenmekte ve çocuklarda nadiren görülen hiperparatiroidizm tartışılmaktadır.

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45, X (50.7%), followed by 45, X/46, XX (10.8%), 46, X, i(Xq) (10.1%) and 45, X/46, X, i(Xq) (9.5%). Mean age at diagnosis was 10.2 +/- 4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45, X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan.
