RESUMEN
OBJECTIVE: The aim of this study was to investigate the relationship between C-reactive protein and erythrocyte sedimentation rate and neutrophil-to-lymphocyte, platelet-to-lymphocyte, and monocyte-to-lymphocyte ratios in acute rheumatic fever in children. METHOD: In this retrospective study, 182 patients with acute rheumatic fever and 173 controls were included. Complete blood count parameters, and neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios were recorded for all the patients underwent transthoracic echocardiography. RESULTS: Neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios were significantly higher in patients with rheumatic heart disease than patients without cardiac involvement (p < 0.05). C-reactive protein and erythrocyte sedimentation rate levels were found to have a positive correlation with neutrophil-to-lymphocyte (r = 0.228, p = 0.001; r = 0.355, p = 0.001), platelet-to-lymphocyte (r = 0.227, p = 0.01; r = 0.149, p = 0.005), and monocyte-to-lymphocyte ratios (r = 0.117, p = 0.005; r = 0.107, p = 0.044). Cardiac involvement was present in 152 (83.5%) of the patients. Neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios were significantly higher in patients with rheumatic heart disease than patients without cardiac involvement (p < 0.05). Patients with carditis were grouped according to mitral, aortic, or both valve involvement but there was no significant difference between the groups with respect to neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios. In addition, neutrophil-to-lymphocyte and monocyte-to-lymphocyte ratios were significantly higher in patients with Sydenham's chorea than without chorea (p < 0.05). CONCLUSION: Neutrophil-to-lymphocyte, platelet-to-lymphocyte, and monocyte-to-lymphocyte ratios may help make the diagnosis of acute rheumatic fever and its prognosis by serial measurements in follow-up but none of them tell us the severity of carditis. Also, this is the first study showing the positive correlation between Sydenham's chorea and neutrophil-to-lymphocyte and monocyte-to-lymphocyte ratios. Further studies are needed to confirm this hypothesis, as this is the first study in the literature on this topic.

IntroductionThe aim of this study is to determine early changes in cardiac function of children with chronic kidney disease by using 2D-speckle tracking echocardiography. METHOD: The study included 38 children - 16 girls and 22 boys - diagnosed as having chronic kidney disease in the nephrology department with a glomerular filtration rate of <90 ml/minute/1.73 m2 for at least 3 months. A total of 37 - 15 girls and 22 boys - age- and sex-matched healthy children were included as the control group. 2D-Speckle tracking echocardiography was performed in all subjects. RESULTS: The mean age was 13.45±2.8 years in patients and 12.89±3.07 years in controls. Systolic and diastolic blood pressures and left ventricular mass index were significantly higher in patients (p<0.05). The values of mitral e, mitral a, mitral e/a ratio, and mitral deceleration time were not different between the groups. Tricuspid annular plane systolic excursion values were lower in patients (p<0.01). Global strain values in apical long-axis 3-chamber and 2-chamber views were significantly lower in patients (p<0.05). Longitudinal, radial, and circumferential peak systolic strain values were lower in patients, but the difference was statistically significant in all segments of longitudinal view and basal segment of circumferential view (p<0.05). Radial and circumferential systolic strain rates were significantly lower in patients in all three segments (p<0.05). Moreover, early diastolic strain rate was significantly lower in longitudinal and radial apical segments and in all segments of circumferential measurements in patients. Besides, strain rate e/a ratio was significantly lower in all longitudinal segments of patients (p=0.01). CONCLUSION: The study concluded that 2D-speckle tracking echocardiography method can determine cardiac involvement earlier than conventional echocardiography in children with chronic kidney disease having preserved ejection fraction.

INTRODUCTION: Microvolt T-wave alternans (TWA) is known to be useful in prediction of ischemia and sudden death in high-risk populations and there are no studies in children with chronic renal failure (CRF). Cardiac problems seem to be responsible for an important part of death in children and young adults with CRF. The aim of this study is to evaluate Holter microvolts TWA measurements in children with CRF comparing to the control group. METHODS: This prospective study included 40 patients with CRF and 48 healthy controls. The history, echocardiography and microvolt TWA values based on 24-hour ECG recordings of the patients were evaluated. Analysis of microvolt TWA was considered on the basis of three leads (V5, V1 and AVF). RESULTS: Compared with the controls, the mean systolic and diastolic blood pressure values and average heart rates were significantly higher in the children with CRF (pâ¯=â¯0.001 and pâ¯=â¯0.026, respectively). Also, the values of left ventricular internal dimensions at end diastole and end-diastolic volume were significantly higher in CRF group (pâ¯=â¯0.01 and pâ¯=â¯0.049, respectively) and couplet ventricular extrasystole was detected in 2 patients with CRF. Consequently, all TWA values in three leads were increased in CRF group than the control group but the only increase in V5 lead was statistically significant (pâ¯=â¯0.028). CONCLUSIONS: This study has demonstrated that microvolt TWA values increased in pediatric patients with CRF. TWA might be used for early risk assessment in pediatric patients with CRF in the future.

MicroRNAs (miRNAs) are fine regulators of gene expression which participate in the regulation of almost every phase of cell physiology, including development of immune cells and adjustment of immune response. In the studies with in vitro/in vivo model systems, specific miRNAs are revealed to have various roles in cardiovascular development and physiological functions. Furthermore, some studies have been done to understand the role of miRNAs about myocarditis, heart failure and coronary artery diseases. miRNAs crucial role in the pathogenesis of other rheumatic diseases have been investigated, however rheumatic carditis was not studied. The aim of this study is to assess values of miRNAs in children with rheumatic carditis and compare them with healthy children. This study included 36 children with rheumatic carditis (mean aged 12.1 ± 2.1 years) and age-gender matched 35 healthy controls (mean aged 11.1 ± 2.3 years). Conventional echocardiography was performed to all subjects. Using real-time polymerase chain reaction, the expression of some miRNAs (hsamiR-16-5p, hsa-miR-221-3p, hsa-miR-223-3p, hsa-miR-10a-5p, hsa-miR-24-3p, hsamiR-92a-3p, hsa-iR-320a, hsa-miR-21-5p, hsa-miR-155-5p, hsa-miR-132-3p, hsamiR-146a-5p, hsa-miR-499a-5p, hsa-miR-1, hsa-miR-125, hsa-miR-196a-5p, hsa-miR-130b-3p, hsa-miR-133b, hsa-miR150-5p,hsa-miR-204-5p, hsa-miR-203a) were analyzed. hsa-miR-16-5p(-1.46 fold, p < 0.01), hsa-miR-223-3p(-1.46 fold, p < 0.01), and hsa-miR-92a-3p(-1.27 fold, p < 0.05) expressions in the patients were lower than those of controls, whereas other examined miRNAs did not differently express between the groups. Results of the study demonstrated that significant downregulation of hsa-miR-16-5p, hsa-miR-223-3p and hsa-miR-92a-3p in children with rheumatic carditis. Since, this is the first study in children with rheumatic carditis, further studies are needed for lightening whether these miRNAs might be helpful as biomarkers.

OBJECTIVES: Recently, mean platelet volume-to-lymphocyte ratio has emerged as a novel parameter of inflammation. No study has investigated the role of mean platelet volume-to-lymphocyte ratio in children with Kawasaki disease. We aimed to evaluate the relationship between mean platelet volume-to-lymphocyte ratio and coronary artery abnormalities in Kawasaki disease. METHODS: Between January 2008 and January 2017, a total of 58 children with Kawasaki disease and 42 healthy subjects matched for sex and age were enrolled. Before the treatment, transthoracic echocardiography for all children was performed. Clinical and laboratory results including mean platelet volume, platelet distribution width, red blood cell distribution width, and counts of platelets, neutrophils, lymphocytes, and white blood cells, erythrocyte sedimentation rate, and C-reactive protein levels were measured. Mean platelet volume-to-lymphocyte ratio was calculated as mean platelet volume divided by lymphocyte count. RESULTS: Compared with healthy controls, mean platelet volume-to-lymphocyte ratio was significantly lower in the children with Kawasaki disease (p<0.01). A total of 14 patients (24.1%) had incomplete Kawasaki disease and 15 (25.8%) children with Kawasaki disease had coronary involvement. Mean platelet volume-to-lymphocyte ratio was significantly lower in patients with coronary artery abnormalities (p<0.01). According to receiver operating characteristic curve analysis performed for the prediction of coronary artery abnormalities, the best cut-off point for mean platelet volume-to-lymphocyte ratio was 2.5 (area under curve=0.593, sensitivity 53.3%, specificity 51.1%). CONCLUSION: It was first shown that the children with Kawasaki disease have lower mean platelet volume-to-lymphocyte ratio compared with control subjects. Mean platelet volume-to-lymphocyte ratio may be helpful in predicting coronary artery lesions in patients with Kawasaki disease.

OBJECTIVE: To determine the values of microvolt T-wave alternans (MTWA) in children and adolescents with Eisenmenger syndrome (ES) and controls. METHODS: Thirteen were included in the study. After analyzing the 24-h ECG recordings, MTWA was considered using three leads (V5, V1, and aVF). Right heart catheterization and 6-minute walk test (6-MWD) were applied to the patients and pro-brain natriuretic peptide levels were assessed; echocardiographic parameters were obtained from both the groups and the results were compared. RESULTS: The MTWA value in lead V5 was 81.08±10.73 µV in the patient group (63.50±18.78 µV in the control group), in lead V1 was 75.00±16.86 µV (73.94±16.77 µV in the control group), and in lead aVF was 73.77±17.81 µV (72.61±16.21 µV in the control group). Comparison of MTWA values between patients and controls revealed that only lead V5 values were statistically different in the ES group. The 6-MWD scores significantly correlated with lead V5. Right atrial volume and right ventricular fractional area change were significantly correlated with lead V1. The Tei index was significantly correlated with lead aVF. CONCLUSION: The MTWA lead V5 value was significantly higher in children with ES than in controls and was also correlated with decreased exercise tolerance.

BACKGROUND: The aim of this study was to investigate whether the outcome of congenital diaphragmatic hernia (CDH) in newborns can be predicted using left ventricular (LV) diameter and estimated pulmonary artery pressure. METHODS: Patients in the newborn unit in 2012-2016 were screened retrospectively. Echocardiographic measurements of 35 patients with isolated left lateral CDH and 27 healthy newborns were compared in the first 24 h of life. RESULTS: Mean LV end-diastolic diameter (LVEDD) and end-systolic diameter (LVESD), and LV ejection fraction were significantly lower in the CDH group. Moreover, tricuspid regurgitation (TR) and pulmonary regurgitation (PR) were significantly higher than in the controls (P < 0.001). Six CDH patients died within the next 40 days after birth. Mean LVEDD and LVESD were significantly lower in the CHD patients who died compared with those who were discharged (P < 0.001, P = 0.016). Also, mean TR and PR (P < 0.001) and the frequency of pulmonary hypertension (PH; P = 0.001) were significantly higher in these patients. On receiver operating characteristic analysis of the CDH non-survivors, LVEDD < 11 mm (sensitivity, 100%; 95%CI: 87.9-100; specificity, 100%; 95%CI: 54.1-100) and TR > 3.5 m/s (sensitivity, 89.66%; 95%CI: 72.6-97.7; specificity, 100%; 95%CI: 54.1-100) were associated with poor prognosis. CONCLUSIONS: Decrease in LVEDD and presence of PH are associated with poor prognosis. Also, PH was associated with mortality in CDH patients. Thus, outcome may be predicted on careful echocardiographic evaluation of the LV diameters and pulmonary pressure.

OBJECTIVES: The aim of the present study was to investigate the relationships between red blood cell distribution width, platelet distribution width, and mean platelet volume and the presence and severity of valvular involvement in patients with rheumatic heart disease. METHODS: Between April, 2012 and December, 2015, 151 patients who were admitted to the Pediatric Cardiology Unit with diagnosis of rheumatic heart disease and 148 healthy children were included to our study. Transthoracic echocardiography for all children was performed, and the values of red blood cell distribution width, platelet distribution width, and mean platelet volume, besides other blood count parameters, erythrocyte sedimentation rate, and C-reactive protein levels were recorded. RESULTS: Red blood cell distribution width, platelet distribution width, mean platelet volume, and C-reactive protein levels were significantly higher in patients with rheumatic heart disease when compared with healthy controls (p0.05). CONCLUSION: This is the first study in children with rheumatic heart disease that demonstrated significantly increased red blood cell distribution width, platelet distribution width, and mean platelet volume levels, as well as evaluated all three parameters together. Furthermore, red blood cell distribution width values in the chronical period of acute rheumatic fever, due to the positive correlation with the other chronic inflammatory markers, may help make the diagnosis in children.

INTRODUCTION: This study is to investigate ventricular repolarization on electrocardiogram (ECG) in a pediatric population receiving methylphenidate (MPH), risperidone (RIS) and combined therapy. METHODS: A total of 215 patients between 6 and 12years with ADHD/conduct disorder receiving methylphenidate, risperidone and combined therapy for minimum 3months and an untreated ADHD group (n=76) was consecutively included in the study. Twelve lead ECG parameters including mean QT, QTc, T-peak to T-end (TpTe) intervals, TpTe dispersion and TpTe/QT ratio were compared. RESULTS: QT interval, and QTc, TpTe interval, TpTe dispersion and TpTe/QTc ratio values for groups receiving RIS, MPH and combined therapy were found to be significantly higher than other groups. Moreover, in the combined therapy group TpTe and TpTe/QTc values were higher than the single drug administration groups (p<0.05). TpTe and TpTe/QT ratio was significantly higher in the RIS group compared to that of the MPH group. CONCLUSION: These results suggested that combined therapy of these drugs had a more prominent impact on the T wave and RIS could be strongly associated with it.

The aim of the current study is to investigate the effects of CO (carbon monoxide) on the cardiovascular system via electrocardiographic, echocardiographic and biochemical findings in children. This prospective study included 22 children with CO poisoning and 24 healthy children as a control group. The CO-intoxicated children were evaluated via electrocardiography and echocardiography 1 h after admission to the emergency department and daily until their discharge from the hospital. Blood gasses, complete blood account, troponin I and creatinine kinase-MB(CK-MB) were assessed daily. Tpeak-end (p:0.001), QTc durations (p:0.02), Tpeak-end dispersion (p:0.001) and Tpeak-end/QT ratio (p:0.001) of CO-intoxicated patients were significantly higher than those in the control group. Mitral E duration (p:0.001), mitral E/A ratio (p:0.001) and left ventricle contractile fraction (p:0.023) at admission were significantly lower, and left ventricle myocardial performance index was higher (p:0.001) in the CO poisoning group. Troponin I and CK-MB levels were higher at admission in 6 (27 %) and 4 (18 %) patients, respectively. The heart is the most critical organ in pediatric CO poisoning. These children present subclinical systolic and diastolic left ventricle dysfunction even in mild cases. Although, in children with acute CO-intoxication ventricular repolarization is impaired, it seems to be reversible like other findings.

AIM: Over the past 2 decades, transcatheter occlusion of patent ductus arteriosus (PDA) with coils and the duct occluders evolved to be the procedure of choice. A new device, the Occlutech PDA® occluder (ODO) device has been designed. Herein, we aimed to evaluate the characteristics and short-term results of patients who underwent transcatheter closure of PDA using the ODO. METHODS: We reviewed the clinical records of 60 patients from different centers in Turkey between December 2013 and January 2016. The medical records were reviewed for demographic characteristics and echocardiographic findings. Device size was selected on the narrowest diameter of PDA. RESULTS: The median patient age was 2.5 years (6 months-35 years), and median PDA diameter was 2.5 mm (1.2-11 mm). Fifty-eight of 60 patients (96.6%) had successful ODO implantation. The occlusion rates were 37/58 (63.7%) at the end of the procedure, 51/58 (87.9%) at 24-48 hours post-procedure, and 57/58 (98.2%) on echocardiography at a median follow-up of 7.6 months. CONCLUSION: Our results indicate that transcatheter closure of PDA using the ODO is effective. Larger studies and longer follow-up are required to assess whether its shape and longer length make it superior to other duct occluders in large, tubular, or window-type ducts.

INTRODUCTION: Nowadays, assessment of brain oxygen saturation, which is simply appliable and noninvasive method, can provide the anesthesia plans to be optimized according to the needs of the brain, which is the main target organ. Brain may be exposed to hypoxia due to supply-demand imbalance of oxygen not only in general anesthesia procedures but also in sedation practices. The aim of the study is to compare the effects of dexmedetomidine and propofol which are widely used agents for pediatric catheterization procedures on brain oxygen saturation using Fore-Sight. MATERIAL AND METHODS: A total of 44 patients undergoing diagnostic cardiac catheterization between 1 and 18 years old were included in the study. All patients, who were randomly divided into two groups, had ASA physical status I-II. In Group Propofol (Group P, n = 22),induction of sedation was made by midazolam (0.5 mg,iv) + propofol (1m/kg,iv), and in Group Dexmedetomidine (Group D, n = 22), induction of sedation was made by midazolam (0.5 mg,iv) +dexmedetomidine (1mcg/kg, iv). Throughout the sedation, cerebral tissue oxygen saturation (SctO 2 ) was recorded by Fore-Sight in addition to routine monitoring. RESULTS: There were no statistically significant differences between the groups in terms of demographic data, hemodynamic data and sedation scores. On other hand, statistically significant decreases in cerebral tissue oxygen saturation were detected especially at 5th and 10th minutes, in Group D, while cerebral oxygenation level did not decrease in Group P. Though, statistically significant difference was determined between two groups in terms of cerebral oxygen saturation, the obtained data was not interpreted as cerebral desaturation. CONCLUSION: As a conclusion, there was a statistically significant but clinically insignificant decrease in cerebral tissue oxygen saturation in dexmedetomidine group compared to propofol group. Although it does not seem to be important in hemodynamic stabilization, we assume that may cause problems for clinically unstable patients.

Ectopia cordis is a rare congenital malformation in which the heart is located partially or totally outside the thoracic cavity. The estimated prevalence of ectopia cordis is 5.5-7.9 per million births and it comprises 0.1% of congenital heart diseases. Ectopia cordis is associated with other congenital heart diseases and various tissue and organ disorders. Common cardiac anomalies associated with ectopia cordis include ventricular septal defect, atrial septal defect, pulmonary stenosis, right ventricular diverticulum, double right ventricular outflow tract and tetralogy of Fallot. Extracardiac anomalies associated with ectopia cordis reported in the literature include omphalocele, gastrochisis, cleft lip and palate, scollosis and central nervous system malformations. Here we report a newborn with ectopia cordis who was diagnosed prenatally.
RESUMEN
OBJECTIVE: The purpose of this study was to compare neurological development of children with cyanotic or hemodynamically impaired congenital heart disease (CHD) and healthy controls by using "Bayley Scales of Infant and Toddler Development Screening Test, Third Edition" (Bayley-III). PATIENTS: Children with CHD (n = 37) and healthy controls (n = 24) aged between 1 and 41 months who were admitted to the Department of Pediatric Cardiology at our university hospital were included. The participants were assessed using Bayley-III test. All patients had cyanotic or hemodynamically impaired CHD. Weight, height, body mass index (BMI), mid-arm circumference (MAC), triceps skinfold thickness (TSF), and head circumference (HC) were measured and standard deviation scores (SDSs) were determined. RESULTS: SDS values of weight, height, BMI, MAC, and TSF of the patients as well as HC values were significantly lower than the control group (P < .001). Compared with controls, the patients had significantly lower mean scores in all Bayley-III subscales (P < .001). We observed similar results in Bayley-III scores including the mean values of cognitive, language, and global motor scores for the CHD patients with and without cardiac surgery (P > .05). CONCLUSION: This study demonstrated that children with cyanotic or hemodynamically impaired CHD have delayed neurodevelopmental outcomes compared with healthy children as assessed using Bayley-III.

AIM: To evaluate the effects of bosentan, sildenafil, and combined therapy on the cardiovascular system using impedance cardiography (ICG) in rats with monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH). METHODS: Seventy male Wistar-albino rats were randomized into five groups. A single dose of MCT was given to all rats, except to the control group. After 4 weeks, bosentan, sildenafil, and combined treatment was started and lasted for 3 weeks. The last group that developed PAH did not receive any medication. Echocardiographic evaluation was performed to determine the PAH development. Thoracic fluid content index (TFCI), stroke volume index (SI), heart rate (HR), cardiac index (CI), and myocardial contractility index (IC) were determined. All procedures were performed at the baseline and after 4 and 7 weeks. RESULTS: Echocardiographic parameters showed that the all MCT-injected rats developed PAH. There were no significant inter- and intra-group differences in TFCI, SI, and IC (P>0.05), but at the 7th week, CI value in the sildenafil-treated PAH rats was significantly higher than in other groups and HR of PAH rats with combined therapy was significantly lower than in other groups. CONCLUSION: PAH did not have an effect on LV function of rats, or if it did, the effect was compensated by physiological processes. Also, sildenafil treatment deteriorated the LV cardiac index.

AIMS: Perinatal hypoxic-ischemic insult has acute and long term deleterious effects on many organs including heart. Although tumor necrosis factor alpha (TNF-α) has been reported to increase soon after hypoxia, the inhibition of this mediator has not been documented. The aim of this study was to investigate the effects of a TNF-α inhibitor (etanercept) on contractility and ultrastructure of rat heart muscles exposed to hypoxia-ischemia during neonatal period. MAIN METHODS: Forty-five seven-day old rats divided into three groups were included in this study. The right carotid arteries of Saline and Etanercept groups of rats were ligated and kept in a hypoxia chamber containing 8% oxygen for 2h. Immediately after hypoxia, while Etanercept group was administered 10mg/kg etanercept, Saline group had only saline intraperitoneally. The carotid arteries of rats in Sham group were located without ligation and hypoxia. Mechanical activity of heart was recorded and tissue samples were examined by electron microscopy in the sixteenth week following the hypoxia-ischemia. KEY FINDINGS: While atrial contractile force in Etanercept group was similar to Sham group, there was significant decrease in Saline group (p<0.001). However, there was only non-significant decrease in ventricular contractility of Saline group comparing to Sham group (p>0.05). After hypoxia-ischemia, ultrastructural degenerative changes and mitochondrial damage in atriums of Etanercept group were significantly less severe than Saline group. SIGNIFICANCE: This study demonstrated that neonatal hypoxia-ischemia caused long term cardiac dysfunction and ultrastructural degenerative changes in the heart of rats.

BACKGROUND: Children with congenital heart disease are under risk of delayed growth and development. We evaluated physical growth parameters and neurodevelopment in these patients in comparison with normal children and examined the effect of hemodynamic status. METHODS: Patients with congenital heart disease (n= 76) and healthy children (n= 51) aged 1-72 months applied to Mersin University Hospital, Mersin, Turkey were included. Patients with heart failure and those requiring intervention or surgery were classified as hemodynamically impaired (HI group, n= 30), and the others, hemodynamically normal (HN group, n= 46). Growth parameters including weight, height, body mass index (BMI), mid-arm circumference (MAC), and triceps skin fold thickness (TSF) were measured and standard deviations (SD) were determined. Functional development was assessed by Denver Developmental Screening Test-II (DDST II). RESULTS: MAC and BMI values of the group with impaired hemodynamic status were significantly lower than the hemodynamically normal and control groups (MAC P < 0.05 and BMI P < 0.01). In the DDST II, the group with hemodynamic abnormality had more failures in gross motor and fine motor skills than HN group and controls (gross motor P= 0.011, P < 0.001 and fine motor P= 0.028, P= 0.001, respectively) and more failures in language development than the control group (P= 0.001). CONCLUSION: The results showed the importance of hemodynamic status in growth and neurodevelopment of children with congenital heart disease. Besides routine growth parameters, more detailed examinations such as BMI, MAC, TSF, and developmental screening tests appear useful in identifying children with cardiac disease who are under risk for delayed growth and development.

BACKGROUND: The purpose of this study was to evaluate left and right ventricular functions by using the Doppler myocardial performance index (MPI), in children with sickle cell anemia (SCA). METHODS: We examined 32 patients with SCA and 30 age-matched healthy children. Echocardiography and Doppler examinations were completed for each of the subjects. MPI was calculated from the Doppler tracings. RESULTS: Compared with controls, left ventricle (LV) end-diastolic diameter, end-systolic diameter, early-diastolic mitral flow velocity and late-diastolic mitral flow velocity were significantly higher in the patients with SCA. Although, the LV ejection fractions were in the normal ranges in patients and controls, both LV and right ventricle (RV) MPI were significantly higher in patients than those in normal children. CONCLUSION: MPI may be a useful noninvasive and sensitive tool for assessing the sub-clinical cardiac LV and RV dysfunctions in patients with SCA.

Impaired cardiac autonomic function may contribute to the risk of sudden unexpected death in epilepsy. Heart rate variability (HRV) is a useful tool for the detection of sympathetic-parasympathetic balance of autonomic nervous system. In the present study, epilepsy patients who had never received antiepileptic medication and those whose seizures have been successfully controlled with antiepileptic drugs were compared with each other and a control group in order to investigate the effects of epilepsy and various antiepileptic drugs on HRV. HRV were tested via 5 min ECG monitoring in 92 patients and 83 controls. Time domain parameters including SDNN, RMSSD and the frequency domain parameters including HF (reflects parasympathetic activity) and LF (reflects sympathetic activity) were assessed. In this group, 78 patients were using antiepileptic drugs including valproic acid (n=33), oxcarbazepine (n=19), phenobarbital (n=11), combined regimens (n=10) and other drugs (n=5), while 14 patients had never received antiepileptic medication. For both of the epilepsy patients groups with or without treatment, time domain parameters were found to be significantly suppressed. In addition, parasympathetic activity was found to be decreased (HF was decreased, LF/HF ratio was increased) in epilepsy patients without antiepileptic drug therapy. Our results indicate that seizure control with antiepileptic drugs may help to improve the cardiac autonomic function impairment in epilepsy patients.

Patients with acute rheumatic fever (ARF) admitted to a tertiary hospital in Ankara between January 1999 and July 2002 were studied cross-sectionally to verify the clinical profile and were followed during the acute period. All patients were investigated for throat culture, streptococcal serologic study, C-reactive protein, and erythrocyte sedimentation rate, and telecardiograms, electrocardiograms and echocardiographic study were done. During the study period, 129 attacks of ARF were observed: 118 were initial attacks and 11 were recurrences. Age on admission was 11.2 +/- 2.73 years (mean +/- SD, range: 6-21 years). Polyarthritis alone was present in 42 cases (33%), carditis alone in 33 (25%), combined carditis and polyarthritis in 36 (28%), combined carditis and chorea in 15 (12%) and chorea alone in 3 (2%). Nineteen (14%) patients with isolated arthritis and pure chorea had silent mitral and/or aortic regurgitation. Carditis was a dominant presenting manifestation, but appeared to be mild or moderate. The present study indicates that ARF is still a significant problem in Turkey. The observation that 8.5% of the attacks were recurrent reaffirms the need for more effective secondary prevention programs.
