Öğe Clinical and Laboratory Characteristics of Hyperprolactinemia in Children and Adolescents: National Survey(Galenos Yayincilik, 2019) Eren, Erdal; Ergur, Ayca Torel; Isguven, Sukriye Pinar; Bitkin, Eda Celebi; Berberoglu, Merih; Siklar, Zeynep; Bas, FirdevsObjective: We aimed to report the characteristics at admission, diagnosis, treatment, and follow-up of cases of pediatric hyperprolactinemia in a large multicenter study. Methods: We reviewed the records of 233 hyperprolactinemic patients, under 18 years of age, who were followed by different centers. The patients were divided as having microadenomas, macroadenomas, drug-induced hyperprolactinemia and idiopathic hyperprolactinemia. Complaints of the patients, their mode of treatment (medication and/or surgery) and outcomes were evaluated in detail. Results: The mean age of the patients with hyperprolactinemia was 14.5 years, and 88.4% were females. In terms of etiology, microadenomas were observed in 32.6 %, macroadenomas in 27 %, idiopathic hyperprolactinemia in 22.7% and drug-induced hyperprolactinemia in 6.4 %. Other causes of hyperprolactinemia were defined in 11.3%. Common complaints in females (n = 206) were sorted into menstrual irregularities, headaches, galactorrhea, primary or secondary amenorrhea and weight gain, whereas headache, gynecomastia, short stature and blurred vision were common in males (n = 27). Median prolactin levels were 93.15 ng/mL, 241.8 ng/ml, 74.5 ng/mL, 93.2 ng/mL, and 69 ng/mL for microadenomas, macroadenomas, idiopathic hyperprolactinemia, drug-induced hyperprolactinemia, and other causes of hyperprolactinemia, respectively. Of 172 patients with hyperprolactinemia, 77.3 % were treated with cabergoline and 13.4 % with bromocriptine. 20.1 % of the patients with pituitary adenomas underwent pituitary surgery. 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.Öğe CLINICAL AND LABORATORY CHARACTERISTICS OF HYPERPROLACTINEMIC CHILDREN AND ADOLESCENTS: NATIONAL SURVEY(Karger, 2017) Eren, Erdal; Ergur, Ayca Torel; Isguven, Sukriye Pinar; Bitkin, Eda Celebi; Berberoglu, Merih; Siklar, Zeynep; Genens, Mikayir[Abstract Not Availabe]Öğe Survey to Investigate Adherence to Growth Hormone Treatment in Children: The Impact of COVID-19 Pandemic(Karger, 2022) Eren, Erdal; Cetinkaya, Semra; Ongen, Yasemin Denkboy; Tercan, Ummuhan; Darcan, Sukran; Turan, Hande; Aydin, Murat[Abstract Not Availabe]Öğe Turner Syndrome and Associated Problems in Turkish Children: A Multicenter Study(2015) Yeşilkaya, Ediz; Bereket, Abdullah; Darendeliler, Fatma Feyza; Baş, Firdevs; Poyrazoğlu, Şükran; Küçükemre Aydın, Banu; Darcan, Şükran; Dündar, Bumin Nuri; Büyükinan, Muammer; Kara, Cengiz; Sarı, Erkan; Adal, Servet Erdal; Akıncı, Ayşehan; Atabek, Mehmet Emre; Demirel, Fatma; Çelik, Nurullah; Özkan, Behzat; Orbak, Zerrin; Ersoy, Betül; Doğan, Murat; Ataş, Ali; Turan, Serap; Gökşen Şimşek, Ruhsar Damla; Tarım, Ömer Faruk; Yüksel, Bilgin; Ercan, Oya; Hatun, Şükrü; Şimşek, Enver; Ökten, Ayşenur; Abacı, Ayhan; Döneray, Hakan; Özbek, Mehmet Nuri; Keskin, Mehmet; Önal, Hasan; Akyürek, Nesibe; Bulan, Kezban; Tepe, Derya; Emeksiz, Hamdi Cihan; Demir, Korcan; Kızılay, Deniz; Topaloğlu, Ali Kemal; Eren, Erdal; Özen, Samim; Abalı, Saygın; Akın, Leyla; Selver Eklioğlu, Beray; Kaba, Sultan; Anık, Ahmet; Baş, Serpil; Ünüvar, Tolga; Sağlam, Halil; Bolu, Semih; Özgen, İlker Tolga; Doğan, Durmuş; Çakır, Esra Deniz; Şen, Yaşar; Andıran, Nesibe; Çizmecioğlu, Filiz Mine; Evliyaoğlu, Saadet Olcay; Karagüzel, Gülay; Pirgon, Mustafa Özgür; Çatlı, Gönül; Can, Hatice Dilek; Gürbüz, Fatih; Binay, Çiğdem; Baş, Veysel Nijat; Fidancı, Muzaffer Kürşat; Polat, Adem; Gül, Davut; Açıkel, Cengizhan; Demirbilek, Hüseyin; Cinaz, Peyami; Bondy, CarolynObjective: 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
