SOTOS SYNDROME: A RARE CAUSE OF TALL STATURE

Sotos sendromu, endokrin bir bozukluk olmaksızın hızlı büyümeyle karakterize birhastalıktır. Ondört yaşında kız hasta boy uzunluğu şikayeti nedeniyle başvurdu. Doğumdave postnatal izlemlerinde boyunun yaşıtlarına göre üst sınırlarda olduğuöğrenilen hastanın klinik incelemelerinde mental retardasyon, makrosefali ve üstsınırda boy persentili saptandı. Bu bulgularla olguya sotos sendromu tanısı konuldu.Bu olgu sunumumuzda aşırı boy uzaması yakınması ile başvuran ve fizik muayenesindedismorfik bulgular saptanan hastaların ayırıcı tanısında sotos sendromunununda düşünülmesinin vurgulanması istenildi.Sotos syndrome is a disorder which is characterized by rapid growth without anyendocrine defect. A 14-year-old female patient was admitted with a complaint of tallstature. Her history revealed that her height was at the upper limits compared to herpeers at the time of birth and during the postnatal follow-ups. Clinical examinationsshowed mental retardation, macrocephaly, and a height percentile at the upper limit.Sotos syndrome was diagnosed with these clinic findings. In this case report, we aimedto stress the necessity of considering the rarely seen Sotos syndrome when making thedifferential diagnosis of patients who apply with the complaint of excessive growth anddemonstrate dismorphic findings at the physical examination

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 lifespa

Clinical and Laboratory Characteristics of Hyperprolactinemia in Children and Adolescents: National Survey

Conclusion: We present the largest cohort of children and adolescents with hyperprolactinemia in the literature to date. Hyperprolactinemia is more common in females and cabergoline is highly effective and practical to use in adolescents, due to its biweekly dosing. Indications for surgery in pediatric cases need to be revised
