RESUMO

INTRODUCTION: Acute rheumatic fever is an autoimmune disease that develops due to streptococcal infection. The positive effect of breastfeeding on the development of the child's immune system is well documented. In this study, we aimed to investigate the effect of breast milk intake period on the development of carditis. MATERIALS AND METHODS: Patients (n: 182) who were diagnosed with acute rheumatic fever between 2010 and 2019 were enrolled in the study. The patients were divided into groups according to carditis development. The demographic, socio-economic, and breastfeeding data were compared between groups. RESULTS: The mean age of the patients was 10.5 ± 3.4, and 43.4 % (n: 79) of them were female. Independent predictors of the development of carditis in the first acute rheumatic fever episode were the number of children at home (OR: 1.773, CI 95%: 1.105, 2.845; p: 0.018) and breast milk intake less than 6 months (OR: 0.404, CI 95%: 0.174, 0.934; p: 0.034). Independent predictors of the development of carditis in any of the acute rheumatic fever episodes were the number of children at home (OR: 1.858, CI 95%: 1.100, 3.137; p: 0.021) and female gender (OR: 3.504, CI 95%: 1.227, 10.008; p: 0.019). The only independently predictor of the development of chorea during acute rheumatic fever was female gender (OR: 3.801, CI 95%: 1.463, 9.874; p: 0.006). CONCLUSION: Although the occurrence of carditis is less common during the first acute rheumatic fever attack in patients with breast milk intake less than six months, this advantage is lost in recurrent attacks. This study showed that breast milk does not have a negative effect on acute rheumatic fever carditis.

RESUMO

AIM: There are increasing reports about the potential role of kynurenine pathway metabolites in autism spectrum disorder (ASD). Early childhood is a very crucial period of time for the etiopathogenesis of ASD and previous studies reported an age-dependent alteration in kynurenine metabolism. However, no study specifically examined kynurenine metabolites in very young children with ASD. This study aimed to investigate kynurenine pathway metabolite levels, kynurenine pathway enzyme activities and neuroprotective index (kynurenic acid/3-hydroxykynurenine ratio) in toddlers and preschool children with ASD. MATERIALS AND METHODS: A total of 68 children with ASD and 44 healthy controls aged between 18 and 60 months were included in this study. Serum levels of kynurenine pathway metabolites were determined by liquid chromatography-mass spectrometry/mass spectrometry system. RESULTS: Serum 3-hydroxykynurenine and kynurenic acid concentrations were significantly higher in the ASD group than in the control group, whereas serum 3-hydroxyanthranilic acid concentrations were significantly lower. CONCLUSIONS: These findings showed that the kynurenine pathway may play a role in the etiopathogenesis of ASD in early childhood.

RESUMO

BACKGROUND: The aim of this study was to investigate the efficacy of computed tomography (CT) findings for characterizing pleural effusions with the use of attenuation values. MATERIAL/METHODS: One hundred and twenty eight patients with pleural effusions on thoracic CT who underwent thoracentesisis within two weeks were studied. Pleural effusions were classified as exudates or transudates according to the Light's criteria. A region of interest was placed for the measurement of Hounsfield Unit (HU) values in the area of the greatest amount of effusion on each slice of the three slices used. CT features that were evaluated for distinguishing pleural exudates from transudates included pleural nodules, pleural thickening and loculation. RESULTS: Thirty three (26%) of the 128 pleural effusions were transudates and 95 (74%) were exudates. The mean HU values of the exudates (8.82±7.04) were significantly higher than those of the transudates (2.91±8.53), (p<0.001). No statistically significant difference was found between transudate and exudate patients in terms of pleural thickness, pleural nodules and loculation (p>0.05). CONCLUSIONS: HU values can help in differentiating exudative pleural effusions from transudative pleural effusions. Because of overlapping HU values, correlation with clinical findings is essential.

RESUMO

BACKGROUND: The aims of this study were to (i) evaluate postoperative arrhythmias following congenital heart surgery, on 12-lead electrocardiography and Holter monitoring; and (ii) analyze the association between the type of repair and postoperative arrhythmia. METHODS: A total of 229 children and 10 neonates with a mean age of 4.71 ± 0.41 years (range, 15 days-17 years) who underwent congenital cardiac surgery were included the study. Twelve-lead electrocardiography and Holter monitoring were used to evaluate arrhythmias after the operation. RESULTS: Within the evaluation period, 104 patients (43.5%) developed arrhythmias after surgery. No arrhythmias were observed in neonates. Female sex (51.9%) was slightly associated with the occurrence of arrhythmias after operation. The most common arrhythmia was supraventricular extra-systoles (65.4%). Risk factors for supraventricular extra-systoles were repair of secundum atrial septal defect (32.3%), ventricular septal defect (25%) and tetralogy of Fallot (14.7%). Also, ventricular extra-systoles were associated with repair of ventricular septal defect. CONCLUSIONS: Postoperative arrhythmia is usually a frequent and transient phenomenon after congenital cardiac surgery, and is provoked by both mechanical irritation of the conduction system and humoral factors. Postoperative arrhythmia should be anticipated in patients with congenital cardiac surgery. Finally, the association between this type of surgical repair and arrhythmia may be helpful for estimating the type of arrhythmia that develops after congenital cardiac surgery in children.

RESUMO

BACKGROUND: Simple electrocardiogram (ECG) markers have been used to evaluate conduction times. Acute rheumatic fever (ARF) is an autoimmune disease that affects these conduction times. The aim of this prospective long-term follow-up study was to evaluate QT, QTc and P-wave dispersions in children with ARF and chronic rheumatic heart disease (CRHD). METHODS: Sixty-four patients with ARF, 33 patients with CRHD and 41 healthy, age- and sex-matched control subjects were included in the study. The ARF patients were divided into two subgroups: carditis and arthritis. Echocardiographic and ECG measurements at the onset of diagnosis and final evaluation were included. RESULTS: QT, QTc and P-wave dispersions were significantly greater in both the ARF carditis and CRHD groups than the ARF arthritis and control subjects during the initial and final analysis (for all, P < 0.001). There was no significant statistical difference in QT, QTc and P-wave dispersion between the initial and final analysis in each groups. Severity of mitral regurgitation and left atrial enlargement were found to be positively correlated with P-wave dispersion (r = 0.438, P < 0.001; r = 0.127, P < 0.001, respectively). QT, QTc and P-wave dispersion greater than 52, 60 and 57 ms, respectively, had higher sensitivity and specificity for predicting ARF carditis. CONCLUSION: These ECG measurements can be used in the diagnosis of ARF carditis as minor criteria with modified Jones criteria. In contrast, this increase in the dispersions is permanent in patients with ARF carditis.

RESUMO

INTRODUCTION: Ischaemia-modified albumin, a novel biochemical marker for tissue ischaemia, was found to be associated with oxidative stress. The purpose of this study was to assess the role of ischaemia-modified albumin in the diagnosis of acute rheumatic fever and also to evaluate the ischaemia-modified albumin levels in children with heart valve disease. METHODS: The study groups, aged 5-18 years, consisted of 128 individuals - 40 with acute rheumatic fever, 35 with congenital heart valve disease, 33 with chronic rheumatic heart disease, and 20 healthy control subjects. RESULTS: The ischaemia-modified albumin, erythrocyte sedimentation rate, and C-reactive protein levels of the acute rheumatic fever group were significantly higher than those in the chronic rheumatic heart disease, congenital heart valve disease, and control groups, separately (p < 0.001). The ischaemia-modified albumin levels in both carditis and isolated arthritis subgroups of children with acute rheumatic fever were significantly higher than in the control group (p < 0.001, p < 0.01, respectively). However, there was no statistically significant difference between the chorea subgroup and control subjects. In addition, significant correlations were observed between ischaemia-modified albumin and acute phase reactants of patients with acute rheumatic fever (p < 0.001 for both erythrocyte sedimentation rate and C-reactive protein). The ischaemia-modified albumin levels of chronic rheumatic heart disease, congenital heart valve disease, and control subjects were similar. CONCLUSIONS: The increased level of ischaemia-modified albumin in children with acute rheumatic fever seems to be associated with inflammation. However, further studies are needed to provide stronger evidence.

RESUMO

This study aimed to investigate homogeneity disorders of ventricular repolarization and atrial conduction via QT dispersion and P-wave dispersion in children with congenital heart disease (CHD) and pulmonary arterial hypertension (PAH). Three groups of 20 each were generated and involved in this study. The first group included 20 children with both CHD and PAH. The second group consisted of 20 children with CHD but no PAH, and the third group was composed of 20 age- and sex-matched healthy children. Electrocardiographic records were used to determine P-wave, QT, and corrected QT (QTc) dispersions. The pulmonary hypertension group compared with the group having no pulmonary hypertension and the control group showed a significantly longer P-wave dispersion duration (39.10 ± 9.54 vs. 26.30 ± 4.99 ms, p < 0.001; and 24.80 ± 6.94 ms, p < 0.001, respectively) and QT dispersion duration (52.80 ± 15.11 vs. 37.60 ± 6.00 ms, p < 0.001; and 35.00 ± 7.77 ms, p < 0.001, respectively). In addition, the durations of maximum QTc and QTc dispersion were significantly longer in pulmonary hypertension group than in the other two groups. The risk of atrial and ventricular arrhythmia was found to be increased in the patients with both CHD and PAH. Physicians should pay close attention to possible atrial and ventricular arrhythmias during the treatment and follow-up evaluation of these patients.

RESUMO

BACKGROUND: Tenascin-C (TnC) is an extracellular matrix glycoprotein that has a major role in tissue remodeling. OBJECTIVE: To evaluate the serum TnC level in acute rheumatic fever (ARF) and chronic rheumatic heart disease (CRHD) during childhood. METHODS: Twenty-five patients with ARF, 25 patients with CRHD and 20 control subjects were included in the study. The TnC levels were analyzed using the enzyme-linked immunosorbent assay method in the ARF group. RESULTS: The TnC levels were lower in the acute carditis group compared with the control group (p < 0.001). The cut-off level was estimated as 2.08 ng/ml for diagnosing carditis with 93.3% sensitivity and 95% specificity. On second analysis, prominent decrease was detected in valve insufficiency patients with markedly elevated TnC levels. In the CRHD group, TnC level was significantly lower in cases with severe valve insufficiency (p < 0.001). CONCLUSIONS: Serum TnC level can be used as a new biochemical marker for diagnosis and predicting the prognosis of rheumatic carditis.

RESUMO

INTRODUCTION: Familial Mediterranean fever (FMF) is one of the common autoinflammatory diseases with multisystemic manifestation. Pleuritis is the only known pulmonary involvement of FMF; however, as far as we know, thoracic involvements in pleural, parenchymal, bronchial, and vascular structures have not been evaluated yet. METHOD: We included 243 consecutive FMF patients who applied to our clinic within the last 5 years and were requested to have a thorax CT for any reason and 122 trauma patients without any comorbidity. An experienced radiologist evaluated the thorax CT images blindly according to the relevant guidelines. We then presented the common incidental pulmonary and mediastinal findings on the thorax CT. Additionally, we compared patients with and without lung involvement according to demographic and disease-related parameters. RESULTS: In our study, 167 of 243 patients (68.7%) had at least one of the pulmonary findings on their thorax CT. The most common pulmonary findings were apical fibrosis in 96 (39.5%) patients, parenchymal fibrotic changes in 48 (19.8%) patients, and a solitary parenchymal nodule smaller than 4 mm in 33 (13.6%) patients. All demographic, genetic, and disease-related characteristics, including the frequency of spondyloarthropathy, were similar in patients with and without pulmonary findings. CONCLUSIONS: We showed that the most common incidental pulmonary finding in our FMF cohort was apical fibrosis on thoracic CT. Our data did not show causality between FMF and apical fibrosis; therefore, more studies are needed to evaluate the frequency and clinical significance of apical fibrosis in FMF. Key Points • More than two-thirds of familial Mediterranean fever (FMF) patients in our study group who underwent a thoracic scan for any reason had pulmonary and mediastinal findings on thorax computed tomography (CT). • In our FMF cohort, the most common incidental pulmonary finding on their thorax CT was apical fibrosis. • All demographic and disease-related characteristics, including the frequency of spondyloarthritis, were similar between patients with and without pulmonary and mediastinal findings.

RESUMO

BACKGROUND: Serum ischemia modified albumin (IMA) levels have been previously studied and found to correlate with some anthropometric and laboratory measurements in adult obesity. IMA had not been studied in obese children and adolescents. OBJECTIVE: The aim of the study is to analyze serum IMA levels and to evaluate their correlation with cardiovascular risk factors in obese children and adolescents with and without metabolic syndrome (MS). SUBJECTS AND METHODS: Sixty-one obese children/adolescents and 33 healthy children were included in the study. The obese group was divided into four subgroups, including MS (n=25), non-MS (n=36), liver steatosis (n=19) and non-liver steatosis (n=42) groups. Blood was collected to analyze biochemical parameters and IMA. Epicardial adipose tissue thickness was measured with echocardiography, and liver steotosis was determined with ultrasonography for each subject. RESULTS: Body mass index (BMI), waist circumferences (WC), left ventricular mass (LVM) and epicardial adipose tissue (EAT) thickness were significantly higher in obese subjects. Serum IMA levels were significantly higher in the metabolic syndrome (MS) and hepatosteotosis groups. Additionally, LVM and EAT thickness were found to be correlated with serum IMA levels in these groups. CONCLUSIONS: Our study suggests that serum IMA levels may be used to predict cardiovascular risk in obese children with MS and hepatosteotosis. This may be related to the duration of obesity in childhood ending in adulthood.

RESUMO

PHACE syndrome is characterized by posterior fossa malformations (P), large facial hemangiomas (H), arterial anomalies (A), cardiac anomalies or coarctation of aorta (C), and eye anomalies (E) and has striking female predominance. Endocrine abnormalities have recently been described in these patients, involving the thyroid and pituitary glands. We report the case of a 2-year-old girl with the clinical features of PHACE with absence of bilateral internal carotid arteries and isolated growth hormone deficiency.

RESUMO

INTRODUCTION: The aim of this study was to investigate the importance of myocardial performance index as an additive criterion to Sarnat criteria in differential diagnosis of newborn babies with moderate and severe hypoxic-ischaemic encephalopathy. METHODS: Our study group included 50 healthy term newborn babies and 20 newborn babies with hypoxic-ischaemic encephalopathy. The 20 newborn babies with hypoxic-ischaemic encephalopathy were scored using Sarnat grades. Left and right ventricular functions were determined on the first day and thereafter in the 1, 3-4, 6-7, and 11-12 months of life by M-Mode and pulsed Doppler. RESULTS: Myocardial performance indexes of the left ventricle were significantly higher in the severe hypoxic-ischaemic encephalopathy group than in the control group during the first, second, and third analyses (p = 0.01, p = 0.02, p = 0.02, respectively) and only during the first analysis (p = 0.01) in the moderate hypoxic-ischaemic encephalopathy group. In addition, the myocardial performance indexes of the right ventricle were significantly higher during the first, second, and third analyses in both severe and moderate hypoxic-ischaemic encephalopathy groups than in the control group (p = 0.01, all). Hypoxia-induced alterations last longer in the right ventricle than in the left ventricle in the moderate group, as during the second and third analyses myocardial performance index continues to be higher than the control group. CONCLUSION: Myocardial performance indexes for the left and right ventricles were significantly higher in both severe and moderate hypoxic-ischaemic encephalopathy groups than in the control group during the first analysis, and myocardial performance index greater than or equal to 0.5 can be used in order to distinguish moderate and severe hypoxic-ischaemic encephalopathy babies according to Sarnat grades as a discriminative additive criterion.

RESUMO

In the literature, cardiac response associated with blunt chest trauma in children has been reported generally as case reports, and interventricular septal rupture due to trauma is quite rare. Interventricular septal rupture can develop even in the absence of visible signs of a trauma because of the flexibility of the chest structure in children. In the present case, a seven-year-old boy with interventricular septal rupture at the mid-muscular region and left ventricle pseudoaneurysm developed due to injury to the left anterior descending coronary artery after a traffic accident is reported. Patients with cardiac murmur detected on physical examination after a blunt chest trauma must be considered as cardiac injury, and in those with signs of ischemia detected on electrocardiography, it should not be forgotten that the coronary artery may be affected.

RESUMO

Objective: Diabetic ketoacidosis (DKA) is an important complication of type 1 diabetes mellitus. We aimed to evaluate the effect of metabolic disorders of DKA on electrocardiography (ECG) parameters in children. Methods: This study was performed between December 2018 and March 2020 and included 39 children with DKA and 40 healthy children. Three ECGs (one before and two after treatment) were obtained from the patient group. P-wave dispersion (Pd), QT dispersion (QTd), QTc dispersion (QTcd), Tp-e intervals, and the ratios of Tp-e/QT and Tp-e/QTc were measured electrocardiographically. ECG parameters from children with DKA and healthy controls were compared statistically. Results: The mean age of the patient group was 10.50±4.12 years. There was no significant difference in terms of age, gender, weight, height and body mass index between patients and controls. In the patient group, a statistically significant increase was found in Pd, QTd and QTcd in the initial ECG compared to the second and third ECGs. Also, when the first and third ECGs were compared, a significant increase in Tp-e and Tp-e/QT was evident in the first ECG. There was a significant difference in the values of Pd, QTd, QTcd, Tp-e and Tp-e/QT in the first ECGs, obtained before DKA treatment, and those values obtained from the control group. Conclusion: This is the first article evaluating Pd and Tp-e parameters in children with DKA. Cardiac arrhythmia risk markers were increased in children with DKA compared to controls. Therefore, clinicians should be aware of the possibility of developing new arrhythmias during DKA treatment.

RESUMO

This study aimed to investigate the role of leptin, ghrelin, neuropeptide Y, and nesfatin-1 in young children with autism spectrum disorder (ASD). A total of 44 children with ASD and 44 healthy controls aged 18-60 months were included. Plasma levels of hormones were measured using commercial enzyme-linked immunosorbent assay kits. Plasma leptin and ghrelin levels were significantly higher in the ASD group than in the control group. However, no significant difference for plasma neuropeptide Y and nesfatin-1 levels was detected between the groups. No relation was found between the severity of ASD symptoms, severity of eating problems, and plasma levels of hormones. Leptin and ghrelin may play a potential role in the pathogenesis of ASD.

RESUMO

BACKGROUND: Acute rheumatic carditis is still an important cause of cardiac failure in developing countries. B-type natriuretic peptides, especially N-terminal segment of its prohormone are now recognised as essential parts of cardiologic evaluation. Increased plasma concentrations of B-type natriuretic peptide and its prohormone are markers of cardiac failure and hypoxia in adults. AIM: To measure the prohormone levels in children with acute rheumatic carditis and to determine whether its concentrations correlate with clinical and laboratory findings. METHODS: A total of 24 children with acute rheumatic carditis and 23 age and sex-matched healthy subjects were entered in the study. Transthoracic echocardiography was performed in all patients to assess the severity of the valve insufficiency and cardiac dysfunction. The prohormone plasma levels were tested for correlation with cardiac dysfunction and other biochemical markers, such as C-reactive protein, erythrocyte sedimentation rate, and anti-streptolysin-O titter. RESULTS: The prohormone plasma concentrations were significantly higher in children with acute rheumatic carditis than in control subjects at the time of diagnosis. A significant decrease of the plasma level was detected among patients after treatments (6-8 weeks). CONCLUSION: We found increased plasma prohormone levels in children with acute rheumatic carditis in the acute stage of illness compared with healthy subjects. Another result is increased plasma prohormone levels as acute rheumatic carditis are reversible.

RESUMO

AIM: The aim of this study was to assess the cardiac functions using conventional echocardiography and tissue Doppler imaging in childhood cancers treated with anthracyclines. METHODS: The study group was selected from the patients admitted to the pediatric oncology department for a treatment protocol that included doxorubicin. Body surface area was calculated and complete 2-dimensional, M-mode, pulse wave Doppler and pulse wave tissue Doppler echocardiographic examinations were performed just before the first treatment and at least 6 months after the last treatment. RESULTS: This study included 20 patients (12 males and 8 females). Mean cumulative antracycline dose was 189 +/- 102.90 mg/m(2). There were no significant differences between the pre- and post-treatment groups regarding systolic and diastolic blood pressures, heart rates, left ventricular ejection fraction and fractional shortening, right and left ventricular conventional and tissue Doppler diastolic parameters (E and A waves, E/A ratio, E' and A' waves, E'/A' ratio), but there were significant differences between the pre- and post-treatment groups regarding body surface area, right and left ventricular myocardial performance index observed by conventional pulse wave and pulse wave tissue Doppler methods. CONCLUSION: Tissue Doppler imaging provided additional information on cardiac functions. While systolic and diastolic functions were in normal range, myocardial performance index observed by tissue Doppler method was impaired in children who were treated with anthracyclines.

RESUMO

Objectives Investigation of the association between epicardial adipose tissue thickness (EATT) and P-wave dispersion (Pd), QT dispersion (QTd), corrected QT dispersion (QTcd) and Tp-e interval in children with Type 1 Diabetes Mellitus (T1DM) was aimed. Methods Forty-one children with T1DM and 41 age- and gender-matched healthy children were included in the study. Demographical characteristics of all cases were examined. In echocardiography; in addition to conventional echocardiographic measurements, end-systolic EATT was measured from right ventricular free wall. In electrocardiogram; Pd, QTd, QTcd and Tp-e interval durations, as well as Tp-e/QT and Tp-e/QTc ratios were calculated. Correlation values between EATT and electrocardiographic parameters were also noted. Results Mean age of the patient group was determined to be 12.43 ± 3.04 years and that of the control group was determined to be 12.08 ± 2.56 years. There was no significant difference between the groups in regard to age, gender, body weight, height and body mass index. In the patient group; EATT, Pd, QTd, QTcd and Tp-e interval were determined to be significantly higher compared to the control group. In the patient group, no significant correlation was determined between EATT and Pd, QTd, QTcd and Tp-e. However, when both patient and control groups were evaluated together, a statistically significant positive correlation was determined between EATT and Pd, QTd, QTcd and Tp-e. Conclusions In children with T1DM, an increase in epicardial adipose tissue thickness and in risk of cardiac arrhythmias has been demonstrated. To reveal the possible unfavorable effects of EATT on cardiac conduction system in T1DM patients needs further studies.

RESUMO

OBJECTIVE: The aim of this study was to determine the usefulness of the Tei Index, an echocardiographic parameter, in the early determination of pulmonary artery pressure (PAP) in congenital heart disease (CHD) with a left-to-right shunt. METHODS: Right and left ventricular functions were evaluated using Tei Index values determined with tissue Doppler echocardiography. Cardiac catheterization was performed in all cases. The presence of pulmonary arterial hypertension (PAH) was defined as a mean PAP of ≥25 mm Hg and a pulmonary vascular resistance index of >3 WU/m2. Patients with a pulmonary/systemic blood flow ratio of ≥2 were considered candidates for surgery. RESULTS: The Tei Index values measured from the left ventricular posterior wall and the right ventricular anterior wall were found to be significantly higher in the patients with PAH (0.68±0.18, 0.67±0.16, respectively) compared with the patients without PAH (0.56±0.16, p=0.027; 0.51±0.12 p=0.001). A significant correlation was detected between the Tei Index value measured from the left ventricular posterior wall and the mean PAP (correlation coefficient: 0.491). CONCLUSION: The right ventricular Tei Index values in children with CHD and a left-to-right shunt can be used as a parameter to follow up on the potential development of PAH, to make a diagnosis in the early period, and to make a timely decision about surgery.
