Bilici M, Fidanci-Dedeoglu Z, Demir F, Akin A, Türe M, Balik H, Tan I, Ertugrul S. Prolonged QT dispersion is associated with pediatric syncope. Turk J Pediatr 2019; 61: 85-91. We aimed to find out whether QT dispersion can be used as a diagnostic marker in terms of syncope type, and recurrence risk. Fifty-two patients (28 male, 53.8%) admitted to the pediatric cardiology clinic with syncope were compared with 50 healthy controls (28 male, 56%; mean age: 13.8±2.3 years, range: 11-17 years) for QT dispersion (QTd) and other electrocardiographic findings. Gender, age, echocardiography, blood pressure while standing and sitting, electrolyte levels, liver and kidney function tests, and QTd and QTcd (calculated with corrected QT: QTc) in electrocardiography (ECG) of patients were all evaluated. Patients` ages varied between 7-17 years and the mean age at first syncope was 13.9±2.4 years. Mean follow-up duration of the patients was 10±5 months (range: 5-18 months). Mean number of syncope attacks was 2.8±2.2. QTd (72±46 ms vs. 34±14 ms) and QTcd (77±45 ms vs. 33±14 ms) values of the patients were significantly longer, compared to control group (p < 0.001). The age, gender, QTd, and QTcd values did not differ between the subtypes of syncope based on pathogenetic mechanism. Additionally, these parameters did not differ in terms of the number of syncope recurrence and tilt test. Patients` complaints reduced after cardiologic evaluation and advice regarding prevention of syncope. We think that in follow-up period, education and preventive precautions that can be taken in the daily life must be emphasized, and drug treatment can be started in unresponsive cases.

Türe M, Bilici M, Akin A, Demir F, Balik H, Darakçi SM. Complete atrioventricular block associated with clozapine intoxication: case report. Turk J Pediatr 2019; 61: 618-621. Clozapine is one of the atypical anti-psychotic drugs used in the treatment of resistant schizophrenia. Although cardiac side-effects are rare, it has been reported that there may be development of myocarditis, dilated cardiomyopathy, postural orthostatic hypotension and prolonged QT duration. Complete atrioventricular (AV) block is characterized by the inability to transmit all of the atrial signal to the ventricles. Causes may be congenital, idiopathic or acquired which are associated with surgery, infection, or muscle disease. AV block is extremely serious and permanent pacemaker insertion is usually necessary for all patients. Complete AV block may develop due to clozapine intoxication through increase in vagal tonus, sinoatrial node (SN) and the inhibition of atrioventricular node signalling. The case presented here is of a 15-year old female patient who developed AV total cardiac block associated with the taking of clozapine in a suicide attempt.

Sabaz MN, Akin A, Bilici M, Demir F, Türe M, Balik H. Factors affecting mortality in children with dilated cardiomyopathy. Turk J Pediatr 2019; 61: 485-492. Dilated cardiomyopathy (DCMP) is a heart disease with high mortality rates that is often seen in children. Genetic and infectious reasons are primary in the etiology. The aim of this study was to investigate the etiology of DCMP and the parameters predicting mortality. A retrospective examination was made of 37 patients diagnosed with DCMP between January 2012 and October 2016. Data were recorded from the patient files of age, gender, complaints on presentation, findings of the physical examination, laboratory test results, echocardiography and electrocardiography findings at the time of diagnosis. These parameters were then compared between the surviving and nonsurviving patients. The patients comprised 21 males with a mean age of 27.50±50 months. Diagnosis was made at the age of < 12 months in 67.6% patients. Within mean 8 months of diagnosis, 16.2% of the patients were lost to mortality and 83.8% of the patients survived. In 83.3% of the non-surviving patients and in 29% of the surviving patients, sinus tachycardia was present at the time of diagnosis (p=0.023). Corrected QT (QTc) at the time of diagnosis was longer in the non-surviving patients (p=0.007). On ECG, the rate of ST-T wave change was higher in the non-surviving patients (80% vs. 17.8%, p=0.012). In conclusion, a significant proportion of the patients were diagnosed below the age of one year. In the non-surviving patients, as sinus tachycardia and ischaemic changes on ECG were seen more often and the QTc was longer, these findings could be considered to be predictors of mortality.

Akin A, Bilici M, Demir F, Yilmazer MM, Ipek MS, Kara H. Percutaneous retrieval of umbilical vein catheter fragment in an infant two months after embolization. Turk J Pediatr 2018; 60: 191-193. Umbilical vein catheterization is frequently preferred and a safe route of venous access especially in newborns. However, some cases with breaking and embolization of those catheters have been rarely reported. Herein we present a two-and-a-half-month-old infant being catheterized within first postnatal week and diagnosed to have embolization of the catheter fragment to conjunction of hepatic vein and right atrium. Percutaneous withdrawal of broken catheter was achieved despite several months after the embolization took place. We suggest that transcatheter removal of catheter fragment embolizations may be safe even in late diagnosis cases.

The aim of this study was to evaluate the feasibility, efficacy and safety of transcatheter closure of patent ductus arteriosus (PDA) with the Occlutech duct occluder (ODO) in children. We reviewed the clinical records of 71 patients who underwent percutaneous closure of PDA with an ODO between September 2014 and August 2016. The Occlutech duct occluder was applied to 71 patients during the study period (September 2014-August 2016), and the results were analyzed in this study. Forty-two of the patients were female and 29 male. The median age was 20.5 months (range, 6-194 months) and median weight was 16 kg (range, 6-68 kg). The PDA was classified as type A in 54 patients (76.1%), type E in 14 (19.7%), type C in 2 (2.8%) and type B in 1 (1.4%) based on the Krichenko classification. A standard ODO device was used for the transcatheter closure procedure in 66 patients and the long-shank ODO device in 5. In the echocardiographic measurement of PDA, the median smallest diameter was 2.7 mm (range, 1.5-7.0 mm), and in the angiographic measurement, the median smallest diameter was 2.5 mm (range, 1.5-6.5 mm). All 71 patients underwent successful PDA closure with the ODO. Angiography following the procedure showed complete closure in 47 patients (66.2%), mild residual shunt in 13 patients (18.3%) and a trivial shunt in 11 patients (15.5%). Color flow Doppler echocardiogpaphy at 24 h post-implantation showed that complete closure was achieved in 65 patients (91.5%), and 6 patients (8.5%) had mild residual shunt. All patients (100%) had complete closure at 30 days of follow-up. The results of this study showed that the Occlutech PDA occluder device is safe and effective in the closure of PDA. As the pulmonary artery side of the device is wider than the aortic side, protrusion toward the aortic side and embolization are prevented, but there is residual shunt in the early period, although this residual shunt disappeared after a few months.

BACKGROUND: The clinical spectrum of Brucella infection is quite diverse and characterized by multi-system involvement. Patients present with myocarditis, endocarditis, or pericarditis. Infective endocarditis is the most common cardiovascular complication in patients with brucellosis. Although conduction abnormalities are seen in cases with endocarditis, they are reported very rarely in the setting of cardiac Brucella infection. CASE REPORT: An eight and a half-year-old male patient was referred to our clinic due to inadequate response to cotrimaxazole plus streptomycin treatment at the 15th day of admission. Although local hospital records on the patient showed a heart rate of 80 bpm, we determined a heart rate of 46 bpm. The electrocardiogram showed complete atrioventricular (AV) block. The average heart rate was determined as 48 bpm with 24-hour Holter electrocardiogram (ECG) monitoring. The echocardiographic examination showed normal-sized heart chambers and the absence of valvular involvement. An agglutination test for brucellosis was found to be positive with a titer of 1/320. High fever, arthralgia, and splenomegaly regressed following doxycycline plus rifampicin therapy, but there was no improvement in the AV block. A permanent pacemaker was implanted because of the detection of an average heart rate of 48 bpm. CONCLUSION: Because cardiac failure and rhythm abnormalities are reported in the course of Brucella infection and may be associated with significant outcomes, cases with brucellosis should be evaluated carefully in terms of cardiac involvement. This report aims to draw attention to complete AV block as an extremely rare complication of Brucella infection.
RESUMO
Double-chambered left ventricle (DCLV) is a rare congenital abnormality in which the left ventricle is divided into two separate chambers by a septum or anomalous muscular structure. The chambers are observed mostly parallel to each other without stenosis, and less frequently in a superior-inferior arrangement. An asymptomatic girl is presented here who was diagnosed with DCLV on echocardiographic examination that was performed for the evaluation of cardiac murmur detected by a pediatrician. She has been followed up without treatment.

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.

Electric shock is a condition that may affect various organ systems and potentially cause death. Cardiac findings vary from asymptomatic mild injury to fatal myocardial involvement. Herein we present a five-year-old boy with a cardiac thrombus developing after an accidental electrical shock. Cardiac arrhythmias and evidence of ischemia have been reported after electric shock; we were, however, unable to identify an earlier case report of intracardiac thrombosis related to electric shock. Findings such as elevated cardiac enzymes and systolic dysfunction, which indicate myocardial damage following electric shock, were present in our patient. We think that the cardiac thrombus might have resulted from the myocardial damage and the slowed intracardiac blood flow related to systolic dysfunction. As the thrombus was thought to have been formed through known mechanisms, it was treated traditionally. However, further data regarding the etiology and management of such thrombi is needed.

Lightning strikes may cause injury to the heart, ranging from slight electrocardiographic changes to fatal damage. As heart injury is the most important cause of mortality in these patients, cardiac monitoring is crucial. Even though various ECG changes have been reported, published data on pathologic ST-segment changes is scarce. Herein, we present a seven-year old patient with ST-segment elevation following a lightning strike. There is not sufficient data regarding lightning-related myocardial ischemia. However, because of the similar effects of lightning strikes and high-voltage electric shocks, we believe myocardial injury related to lightning may be managed in the same manner as is cardiac involvement associated with electric shock.

ABSTRACT OBJECTIVE: To determine the factors affecting the smoking habits of high school students, their thoughts about changes resulting from anti-smoking laws, and how they are affected by those laws. METHODS: In this cross-sectional study, 11th-grade students at eight high schools in Ankara, Turkey, were invited to complete a questionnaire. RESULTS: A total of 1,199 students completed the questionnaire satisfactorily. The mean age of the respondents was 17.0 0.6 years; 56.1% were female, of whom 15.3% were smokers; and 43.9% were male, of whom 43.7% were smokers (p < 0.001). The independent risk factors for smoking were male gender, attending a vocational school, having a sibling who smokes, having a friend who smokes, and poor academic performance. Of the respondents, 74.7% were aware of the content of anti-smoking laws; 81.8% approved of the restrictions and fines; and 8.1% had quit smoking because of those laws. According to the respondents, the interventions that were most effective were the (television) broadcast of films about the hazards of smoking and the ban on cigarette sales to minors. The prevalence of smoking was highest (31.5%) among students attending vocational high schools but lowest (7.5%) among those attending medical vocational high schools. Although 57.1% of the smokers were aware of the existence of a smoking cessation helpline, only 3.7% had called, none of whom had made any attempt to quit smoking. CONCLUSIONS: Although most of the students evaluated were aware of the harmful effects of smoking and approved of the anti-smoking laws, only a minority of those who smoked sought professional help to quit.
RESUMO OBJETIVO: Determinar os fatores que afetam os hábitos de fumar de estudantes do ensino médio, seus pensamentos sobre as mudanças resultantes das leis antifumo e como eles são afetados por essas leis. MÉTODOS: Neste estudo transversal, alunos do 11º ano de oito escolas de ensino médio em Ancara, Turquia, foram convidados para preencher um questionário. RESULTADOS: Preencheram o questionário 1.199 estudantes de forma satisfatória. A média de idade dos participantes foi de 17,0 0,6 anos; 56,1% eram mulheres; das quais 15,3% eram fumantes; e 43,9% eram homens, dos quais 43,7% eram fumantes (p < 0,001). Os fatores de risco independentes para o tabagismo foram ser homem, frequentar escola técnica, ter um irmão/irmã que fuma, ter um amigo que fuma e ter baixo desempenho acadêmico. Dos participantes, 74,7% conheciam o conteúdo das leis antifumo; 8,1% aprovavam as restrições e multas, e 8,1% haviam cessado o tabagismo devido a essas leis. Na opinião dos participantes, as intervenções mais efetivas foram a exibição de curtas na TV sobre os malefícios do tabagismo e a proibição da venda de cigarros a menores. A prevalência do tabagismo foi maior (31,5%) nos estudantes de escolas técnicas, mas menor (7,5%) nos estudantes de escolas técnicas médicas. Embora 57,1% dos fumantes soubessem da existência de um serviço telefônico de ajuda para a cessação tabágica, somente 3,7% haviam ligado para esse serviço, mas nenhum tentou parar de fumar. CONCLUSÕES: Embora a maioria dos alunos avaliados conhecesse os efeitos deletérios do tabagismo e aprovasse as leis antifumo, apenas uma minoria dos fumantes procurou ajuda profissional para a cessação tabágica.

BACKGROUND: Familial Mediterranean fever (FMF) is an inflammatory disease, which is suggested to be associated with increased risk of atherosclerosis. Epicardial adipose tissue (EAT) thickness and the mean platelet volume (MPV) are parameters used in prediction of atherosclerotic risk in various conditions. These parameters were evaluated in children with FMF and compared with healthy controls. METHODS: Forty-five patients with FMF and 54 age- and gender-matched healthy controls were assessed. Duration of symptoms, age at diagnosis, duration of delay in diagnosis, frequency and duration of FMF attacks, disease severity scores, response to colchicine therapy, MEditerraneanFeVer (MEFV) gene mutations, and MPV values were recorded. EAT thicknesses were measured by echocardiography. RESULTS: Epicardial adipose tissue thicknesses of the children with FMF were found to be significantly greater than that of controls (5.1 ± 1.4 vs. 4.5 ± 0.9 mm, p=0.036). FMF patients had significantly higher MPV values compared with the controls (7.8 ± 1.1 vs. 7.3 ± 1.4 fl, p=0.044). Age at diagnosis, duration of delay in diagnosis, and MPV values were found to be correlated with EAT thickness in the patient group (r=0.49, p=0.001 for the former parameters and r=0.32, p=0.04 for MPV). CONCLUSION: Epicardial adipose tissue thickness and MPV values seem to be increased in children with FMF. These findings may indicate an increased risk of atherosclerosis in FMF patients.

OBJECTIVE: To evaluate the epidemiologic, clinical and laboratory characteristics of a group of children with type 1 diabetes mellitus (T1DM) living in a Turkish city. METHODS: The records of 395 (boys/girls: 199/196) children with newly diagnosed T1DM hospitalized in the years 1985-2004 were evaluated retrospectively. The data were assessed by gender and age subgroups (≤5, 6-10 and ≥11 years). RESULTS: Mean age of children at diagnosis was 8.1±4.1 years. At T1DM onset, the number of children ≤5, between 6-10 and ≥11 years old was 110 (27.9%), 147 (37.2%) and 138 (34.9%), respectively. The patients were mostly diagnosed at ages 6-8 years (24.1%), followed by cases aged 3-5 years (22.0%). Polyuria and polydipsia were the most common symptoms (94.7%). Mean duration of symptoms was 21.5±18.6 days. Although the patients mostly presented in autumn (30.7%), no season-related significant differences were found. The frequency of ketoacidosis was relatively high (48.5%). When compared to boys, the girls experienced higher rates of ketoacidosis (55.1% vs. 41.7%, p=0.042); had a higher frequency of anti-thyroid peroxidase antibodies (11.7% vs. 4.2%, p=0.049) and higher insulin requirement (0.89±0.41 vs. 0.77±0.36 IU/kg, p=0.005). Cases with a family history of T1DM were more likely to have anti-endomysial antibodies (42.9% vs. 8.1%, p=0.027) and higher initial blood glucose levels (510.5±145.0 vs. 436.1±156.5 mg/dL, p=0.005). CONCLUSION: The findings possibly indicate a decreasing age of T1DM onset. The high frequency of ketoacidosis at presentation is noteworthy. Girls had higher rates of ketoacidosis, higher frequency of anti-thyroid antibodies and higher insulin requirements as compared to boys. Patients with a family history of T1DM had higher initial glucose levels and higher frequency of anti-endomysial antibodies.

In this prospective study, we aimed to assess left and right ventricular function in terms of the presence of right bundle branch block (RBBB) in the cases with repaired ventricular septal defect (VSD). Fifty-three patients who had VSD surgery at least 1-year preceding admission and 52 healthy controls were enrolled into the study. All the participants underwent electrocardiographic and echocardiographic examination. The cases with RBBB were determined. The conventional and tissue Doppler echocardiographic measurements of the patients with and without RBBB were compared with each other and healthy controls. Twenty-eight of VSD repair groups were male and 25 were female. Control group consisted of 30 males and 22 females. The mean age of the study and control groups was 7.5 ± 5.0 and 6.9 ± 4.3 years, respectively. RBBB was detected in 20 of 53 (37.7 %) operated patients. The only significant difference between the cases with and without RBBB was decreased right ventricular fractional area change (%) in the former group (33 ± 7 vs. 39 ± 5 p < 0.05). When compared to controls, operated group had statistically lower [corrected] tricuspid annular plane systolic excursion (p < 0.05), lower systolic, early diastolic, and late diastolic myocardial velocities, higher left and right ventricular myocardial performance indices, irrespective of the presence of RBBB. The ratios of mitral or tricuspid inflow to left or right ventricular myocardial in early diastolic velocities measured from lateral annular levels were increased in operated group (all p values <0.05). In conclusion, RBBB in the cases with surgical VSD repair might be associated with right ventricular dysfunction. Biventricular systolic and diastolic dysfunction may develop following VSD repair irrespective of the presence of RBBB. Tissue Doppler-derived myocardial performance indices are useful in detection of those subclinical dysfunctions.

BACKGROUND: Kawasaki disease is an inflammatory condition. Neutrophil to lymphocyte ratio is a marker reflecting inflammation. AIMS: The aim of the study is to evaluate usefulness of neutrophil to lymphocyte ratio in diagnosis of Kawasaki disease and in prediction of coronary artery lesions. STUDY DESIGN: Retrospective cross-sectional study. METHODS: Seventy-five children with Kawasaki disease and 66 controls were retrospectively enrolled. Their leukocyte, neutrophil, and lymphocyte counts were recorded. Abnormally distributed data were shown as median (interquartile range). Cases having coronary artery diameter two standard deviation above mean were diagnosed to have coronary artery lesions. RESULTS: Median age of Kawasaki disease patients was 34 months. Twentyfive of those (33.33%) had incomplete Kawasaki disease and twenty-six (34.66%) had coronary artery lesions. Leukocyte [12.61 (6.09)×10(3)/µL vs. 8.48 (5.58)×10(3)/µL], neutrophil [6.73 (4.10) ×10(3)/µL vs. 4.62 (5.47)×10(3)/µL], and lymphocyte [4.04 (2.91)×10(3)/µL vs. 3.02 (2.57) ×10(3)/µL] counts were significantly higher in Kawasaki disease patients compared to controls (all p values <0.01). However, there was not significant difference between patients and controls regarding neutrophil to lymphocyte ratio [1.72 (1.22) vs. 1.71 (1.88)]. Findings of Kawasaki disease and incomplete Kawasaki disease cases did not differ, while comparison of patients with and without coronary artery lesions revealed significantly higher neutrophil to lymphocyte ratio values in former group [2.02 (1.63) vs. 1.50 (1.28), p=0.01]. The cut-off neutrophil to lymphocyte ratio value for prediction of coronary artery lesions was determined as 1.32. CONCLUSION: Neutrophil to lymphocyte ratio values in Kawasaki patients with coronary lesions were significantly higher than the ones without and values greater than 1.32 were useful in prediction of coronary lesions.
