Amaç: Dikkat Eksikliği ve Hiperaktivite Bozukluğu (DEHB) tanısı ile metilfenidat kullanan hastalarda sık olmasa bile kardiyovasküler yan etkiler görülebilmektedir. Bu konu ile ilgili literatürde az sayıda çalışma bulunmaktadır. Bu çalışma ile DEHB olan çocuklarda metilfenidat kullanımının kardiyovasküler sistem üzerindeki etkilerini araştırmayı planladık. Gereç ve Yöntemler: Hastanemiz Çocuk Psikiyatrisi Kliniği tarafından Mayıs 2011-Mayıs 2012 tarihleri arasında DEHB tanısı ile metilfenidat tedavisi başlanan 141 hasta incelendi. Tedavinin ilk bir ayında kardiyovasküler semptom tariflemiş olan otuz hastaya ait demografik özellikler, kalp hızı, sistolik ve diyastolik kan basıncı, elektrokardiyografi (EKG) ile QTc süresi ve 24 saatlik ritim Holter sonuçları retrospekfik olarak değerlendirildi. Bulgular: Değerlendirilen 30 hastanın (8 kız, 22 erkek) yaş ortalaması kızlarda 10±3 yaş iken erkeklerde 9±2.2 yaştı. Tedavinin 1. ayında ortalama QTc süreleri hastalarda artmış olarak saptandı ve istatistiksel olarak anlamlı bulundu. Fakat hiçbir hastada QTc süresindeki uzama patolojik düzeyde değildi. Kız hastaların ortalama sistolik ve diyastolik kan basınçlarında ilk ayın sonunda artma olmasına rağmen istatistiksel olarak anlamlı bulunmadı. Benzer şekilde hastaların ortalama kalp hızlarında da artış vardı, ancak istatistiksel olarak anlamlı değildi. Başlıca semptomlar 14 hastada (%46.6) çarpıntı, 10 hastada (%33.4) göğüs ağrısı, 4 hastada (%13.4) çarpıntı ve göğüs ağrısı ve 2 hastada (%6.6) nefes darlığı idi. Bu hastaların tümünde EKG ve 24 saatlik ritim Holter sonuçlarının normal olduğu, ancak iki hastada tetkik sonuçları normal olmasına rağmen ailelerinin isteği ile tedavinin sonlandırıldığı görüldü. Sonuç: Bu çalışmada, metilfenidat tedavisinin kardiyovasküler sistem üzerine etkileri ortaya konulmaya çalışıldı. QTc süresinde uzamanın istatistiksel olarak anlamlı olduğu, ancak bu uzamanın patolojik sınırları geçmediği görüldü.
Objective: Some cardiovascular side effects can be seen in patients receiving methylphenidate treatment with a diagnosis of attention deficit and hyperactivity disorder (ADHD), although not frequent. There are few studies in the literature conducted in these patients about this issue. We aimed to investigate the early effects of methylphenidate on the cardiovascular system in children with ADHD in this study. Material and Methods: We analyzed 141 patients receiving methylphenidate treatment for ADHD in the pediatric psychiatry clinic of our hospital between May 2011 and May 2012. We retrospectively evaluated the demographic characteristics, heart rate, systolic and diastolic blood pressures, QTc duration at electrocardiogram (ECG) and 24-hour rhythm Holter results of thirty patients who had cardiovascular symptoms in the first month of treatment.Results: We evaluated a total of 30 patients (8 female and 22 male) with a mean age of 10±3 years for females and 9±2.2 years for males. The mean QTc duration increased at the end of the first month of treatment and the change was statistically significant. However, no patient had pathological prolongation of QTc duration. Although the mean systolic and diastolic blood pressures increased in female patients at the end of first month, this increase was not statistically significant. Similarly, there was an increase in the mean heart rates of the patients at the end of first month, but it was not statistically significant. The main symptoms of the patients were palpitation in 14 patients (46, 6%), chest pain in 10 patients (33.4%), palpitation and chest pain in 4 patients (13,4%) and dyspnea in 2 patients (6.6%). ECG and 24-hour rhythm Holter monitoring findings were normal in all patients. However, methylphenidate treatment was terminated in two patients because of the request of their families despite completely normal test results.Conclusion: This study was performed to demonstrate the early effects of methylphenidate treatment on the cardiovascular system in ADHD patients. This treatment caused prolongation of QTc duration, which was statistically significant but within normal ranges

The publication language of Turkish Journal of Pediatric Disease is English.
Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.
The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
