Publication Metadata only A case of glycogen storage disease type II with double aortic arch(WILEY, 2000) AKALIN, FİGEN; Akalin, F; Alper, G; Oztunc, F; Kotiloglu, E; Turan, SPublication Metadata only Increased QT dispersion in epileptic children(WILEY, 2003) AKALIN, FİGEN; Akalin, F; Tirtir, A; Yilmaz, YAim: Epilepsy is a common paroxysmal disorder in childhood. Tachyarrhythmia, bradyarrhythmia, asystole, atrioventricular block, ventricular fibrillation or sudden death may occur during seizures. Mutations of ion-channel coding genes are found in patients with idiopathic or cryptogenic epilepsy. The ion channels also play a role in arrhythmogenesis. QT dispersion is a non-invasive method for assessment of regional repolarization differences within the myocardial tissue. This study investigated QT and QTc dispersion (QTcd) and the risk of dysrhythmia in epileptic children. Methods: The first group included 28 patients with newly diagnosed epilepsy and not taking antiepileptic treatment (range 10 mo to 15 y, mean+/-SD 6.86+/-3.92 y), the second group included 34 patients taking antiepileptic treatment (range 1-14 y, mean+/-SD 7.51+/-3.68 y) and the control group included 52 healthy children (range 4 mo to 15 y, mean+/-SD 6.94+/-3.92 y). Twelve-lead ECGs were obtained and heart rate, RR interval, P wave amplitude and duration, PR interval, QRS duration, QRS axis and QT intervals were measured, and QTc, QTd, QTcd were calculated in all subjects. The measurements were repeated in the first group under antiepileptic treatment. Results: While no significant difference in terms of heart rate, RR interval, P wave amplitude and duration, PR interval, QRS duration, QRS axis, QT intervals or QTc intervals was found, QTd and QTcd values were significantly increased in epileptic children compared with,the control group. QTd was 58.1+/-13.4 ms and 35.9+/-9.3 ms and QTcd was 91.0+/-22.9 and 68.6+/-18.0 ms in patients and controls, respectively. Antiepileptic treatment did not affect QT dispersion. Conclusion: QT dispersion is increased in epileptic children. Further investigation is needed to reveal the pathogenesis of myocardial repolarization abnormalities in epileptic patients.Publication Metadata only High-sensitivity C-reactive protein in children at risk for coronary artery disease(BLACKWELL PUBLISHING, 2007) AKALIN, FİGEN; Guran, Omer; Akalin, Figen; Ayabakan, Canan; Dereli, Feyza Yagmur; Haklar, GoncagulAim: To determine the value of high-sensitivity C-reactive protein (hs-CRP) in predicting risk factors for coronary heart disease (CHD) in children. Methods: We measured hs-CRP levels in 51 children (11.79 +/- 3.14 years) with risk factors for CHD (hypercholesterolemia, hypertension, obesity, low HDL cholesterol and familial history of CHD). The results were compared with 26 children (12.98 +/- 2.59 years) without any risk factors. Results: The children with risk factors had significantly higher serum levels of hs-CRP compared to the control group (3.33 +/- 4.58 vs. 0.92 +/- 1.90 mg/L, respectively, p < 0.01). CRP concentrations significantly increased in children with three or more risk factors. Hs-CRP levels correlated to body mass index (r = 0.411, p = 0.003), diastolic blood pressure (r = 0.323, p = 0.021), fibrinogen (r = 0.447 and p = 0.004) and HDL cholesterol levels (r = -0.461 and p = 0.001). Cutoff value for CRP was 1.04 mg/L with 58% sensitivity and 92% specificity. Conclusion: Serum hs-CRP level is a useful marker in screening the children who are under the risk of CHD in adulthood. Early identification of the children with risk factors and intervention for obesity, harmful habits and life style in childhood might decrease the incidence of coronary heart disease in adulthood.Publication Metadata only Effects of childhood bronchiectasis on cardiac functions(2003) AKALIN, FİGEN; AkalIn, Figen; Köroglŭ, Tolga F.; Bakaç, Serap; Dagli, ElifBACKGROUND: Bronchiectasis is still a widespread disease in developing countries. It is an important cause of mortality and morbidity. The information on cardiac involvement in bronchiectasis is limited. However, cor pulmonale is common in patients with chronic lung disease, such as cystic fibrosis. METHODS: We utilized echocardiography and exercise tests, along with clinical scoring, chest radiograph scoring, and pulmonary function tests in 21 patients to determine whether detectable changes in cardiac functions were present, and the nature of their relationship to the underlying disease severity. RESULTS: The ventricular systolic functions were preserved in all patients. Some of the patients had changes in left ventricular diastolic function indices, characterized by abnormal Ewave/Awave (E/A) ratios or isovolumetric relaxation time values. Isovolumetric relaxation time but not E/A ratios was found to have a significant negative correlation with the clinical score. In addition, exercise capacity was decreased in bronchiectatic children. Most of the patients stopped the exercise test due to exhaustion before reaching maximum heart rate. CONCLUSION: Left ventricular diastolic functions are affected in bronchiectasis, and the performance of patients is dependent on their pulmonary status. This is the first study demonstrating the cardiac effects of bronchiectasis according to our survey of the published literature.Publication Metadata only Increased QT dispersion in breath-holding spells(WILEY, 2004) AKALIN, FİGEN; Akalin, F; Turan, S; Guran, T; Ayabakan, C; Yilmaz, YAim: Breath-holding spells are common in infancy and early childhood, and patients are frequently referred to paediatric cardiology clinics for exclusion of heart disease. Recent data reveal subsequent development of epilepsy and neurocardiogenic syncope. Autonomic dysregulation and increased vagal stimulation leading to cardiac arrest and cerebral ischaemia is considered as the cause. Iron deficiency anaemia may be associated with these spells. We studied QT dispersion for the assessment of ventricular repolarization in these patients. Methods: The study group consisted of 19 girls and 24 boys between 3 and 108 mo of age (mean +/- SD = 22.7 +/- 17.7 mo); and the control group consisted of 13 girls and 12 boys between 3 and 57 mo of age (mean +/- SD = 22.9 +/- 15.1 mo). QT interval was measured; corrected QT interval (QTc), QT dispersion (QTd) and QTc dispersion (QTcd) were calculated from 12-lead surface electrocardiograms of the patients and the control group. Results: There was no statistically significant difference in terms of QT and QTc intervals between patient and control groups, while QTd and QTcd values were significantly increased in patients with breath-holding spells compared to the healthy children. QT dispersion was 59.5 +/- 35.9 ms and 44.8 +/- 11.9 ms, respectively, in patients and controls (p < 0.05). QTc dispersion was 102.1 +/- 41.9 ms and 79.6 +/- 24.6 ms, respectively (p < 0.01). The presence of iron deficiency did not effect the QT and QTc dispersion. Conclusion: QT dispersion is increased in patients with breath-holding spells, and this finding justifies further investigation for rhythm abnormalities and autonomic dysfunction in this patient group.
