RESUMO

Background and objectives Accumulating studies have pointed out that gut-blood and blood-brain barrier dysfunctions due to the alterations in permeability may play a role in the pathophysiology of neurodevelopmental disorders. Tight junctions are crucial components of these barriers and some peptides including claudin-5, occludin, zonulin and tricellulin are important components of these structures. This study aimed to investigate the relationship between these molecules and attention deficit hyperactivity disorder (ADHD) in children and adolescents. Methods A total of 57 children with ADHD and 60 controls aged between 6 and 12 years were included in the study. The severity of ADHD symptoms was assessed through a parent-rated questionnaire, and Conner's Continuous Performance Test was administered to the study group. Serum levels of biochemical variables were measured using enzyme-linked immunosorbent assay kits. Biochemical parameter levels and scale scores were compared using Mann-Whitney U or Student's t tests. In addition, a multivariate analysis of covariance (MANCOVA) and a one-way analysis of covariance (ANCOVA) was performed on the outcome variables. Finally, a hierarchical regression model was conducted on the study group. Results Serum claudin-5 and tricellulin levels were significantly lower in the ADHD group compared to the control group. The difference between the groups in terms of serum claudin-5 and tricellulin levels remained significant after controlling for confounding factors such as age, gender and autistic characteristics. There was no significant difference between the groups in terms of serum zonulin and occludin levels.Conclusion These results reveal that claudin-5 and tricellulin levels vary in patients with ADHD. Alterations in these peptides may affect the brain by leading to a dysregulation in intestinal or blood-brain barrier permeability. The causal relationship between these peptides and ADHD requires further ... (AU)

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

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

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

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.

RESUMO

BACKGROUND: Volumetric shrinkage of normal tissues such as salivary glands, kidneys, hippocampus are observed after radiotherapy. We aimed to assess the alterations in pancreatic volume of patients who received abdominal radiotherapy and define pancreas as an organ at risk for radiation treatment planning. MATERIAL-METHODS: Forty-nine patients operated for gastric adenocarcinoma who received adjuvant abdominal radiotherapy were in the study group, 27 patients with early stage disease who did not need adjuvant treatment after surgery comprised the control group. An experienced radiologist contoured the pancreas of all the patients from computed tomographies imported to the planning system obtained either for radiation planning purpose or for follow-up after surgery. The same procedure was repeated one year later for both groups. Measured volume of the pancreas was expressed in cm3. RESULTS: Mean pancreatic volumes were similar in both groups at the onset of the study, 51,34 ± 20,33 cm3, and 50,12 ± 23,75 cm3 in the irradiated and the control groups respectively (p = 0,63). One year later, mean pancreatic volumes were significantly decreased in each group; 22,48 ± 10,53 cm3, 44,18 ± 23,08 cm3 respectively, p < 0,001. However, the decrease in pancreatic volume was significantly more pronounced in the irradiated group in comparison to the control group, p < 0,001. CONCLUSION: Volumetric decrease in normal tissues after radiotherapy is responsible for loss of organ function and radiation related late side effects. Although pancreas is a radiation sensitive organ losing its volume and function after radiation exposure, it is not yet considered as an organ at risk for radiation treatment planning. Pancreas should be contoured as an organ at risk, dose-volume histogram for the organ should be created, and safe organ doses should be determined. This is the first study declaring pancreas as an organ at risk for radiation toxicity and the necessity of defining dose constraints for the organ.

RESUMO

Tracheobronchomegaly (TBM) is a rare disease of unknown etiology, characterized by dilatation of the trachea and main bronchi. Despite its rarity, TBM has been reported to accompany several conditions, particularly Ehlers-Danlos syndrome. Herein, we report on a 15-year-old patient who was diagnosed with TBM on the basis of radiologic and endoscopic findings and with Ehlers-Danlos syndrome type IVB presenting with marfanoid features, severe kyphoscoliosis, increased skin elasticity, and ongoing hypotonia since the neonatal period.

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

ABSTRACT Objective: To evaluate the Magnetic Resonance Imaging (MRI) findings and their validity in patients with ischiofemoral impingement syndrome (IFI) . Methods: We retrospectively analyzed 55 hips. MRI findings of 30 hips were consistent with IFI syndrome. Twenty five hips had no MRI findings consistent with IFI syndrome. We compared the ischiofemoral space (IFS), quadratus femoris space (QFS), ischial angle (IA) and femoral neck angle (FNA) between the age and gender matched groups. We also analyzed edema, fatty replacement and partial or total rupture of quadratus femoris muscle. Mann Whitney U test was used to compare the data. Results: We observed atrophy in eight, fatty replacement also in eight and edema in all of the quadratus femoris muscle. QFS (p<0.001) and IFS (p<0.001) were significantly lower in patients as compared to the control group. IA (p=0.012) and FNA (p=0.010) values were significantly higher in patients compared with the control group. Conclusion: MRI findings of IFI include narrowing of QFS and IFS and increase in IA and FNA. This condition should be kept in mind for patients with hip pain. Level of Evidence III, Retrospective Study.

RESUMO

PURPOSE: To evaluate the relationship of apparent diffusion coefficient (ADC) values of renal parenchyma with chronic kidney disease (CKD) stage and serum creatinine levels. MATERIALS AND METHODS: One hundred and ten patients who had undergone magnetic resonance imaging of the upper abdomen for different reasons were retrospectively studied. A region of interest (ROI) was placed on the renal parenchyma for measurement of ADC values of both kidneys, without any preference for cortex or medulla. Three circular ROIs were placed-one each in the upper pole, interpolar region and lower pole of both kidneys. The mean ADC values were recorded for each patient and the relationship between ADC values and stage of CKD and serum creatinine levels were evaluated. RESULTS: Statistically significant difference was determined between the ADC values of the cases according to CKD stages (p < 0.001). Paired comparisons performed to determine the group that caused the difference revealed that median ADC values of healthy subjects who formed the control group was statistically significantly higher than that of the cases with stage 3, stage 4 and stage 5 CKD (p: 0.008; p: 0.008; and p: 0.002, respectively). Sensitivity and specificity were found to be 75.44% and 69.81%, respectively in detecting stage 3, stage 4 and stage 5 CKD among the cases with ADC values of 1151 and lower. CONCLUSION: ADC values can play a role in the evaluation of renal dysfunction. However, population-and protocol-based cut-off ADC values are needed to identify renal dysfunction and to distinguish between different stages of CKD.

RESUMO

OBJECTIVE: Digitalis preparations are commonly used by children and adults with heart diseases worldwide, although excessive doses may cause cardiac effects. The aim of the study is to evaluate the antiarrhythmic effect of Crataegus oxyacantha extract on digoxin-induced arrhythmias in anesthetized Wistar rats. METHODS: Control and experimental groups were evaluated for arrhythmias induced by digoxin. Fifteen rats (7 as controls and 8 as the experimental group) were included in the study. The dry fruits of 100 mg Crataegus oxyacantha were extracted by percolation method. Digoxin, at a dose of 40 µg/kg/min, was infused to form the arrhythmias in all rats. Simultaneously, the extract was infused into the experimental group, while 0.9% NaCl was infused into control group. Electrocardiographic QRS prolongation and arterial blood pressure changes were analyzed. RESULTS: The experimental group lived longer (62.13±2.20 min) than the controls (p=0.002). On the other hand, the time to beginning of QRS prolongation did not differ between the two groups (p=0.812). Bradycardia was significant in the control group (288.01±10.54 beat/min and p=0.01). The maximum QRS duration was observed in the control group during the digoxin and 0.9% NaCl infusion period (53.29±3.99 ms and p=0.001). Also, the durations of atrial and ventricular arrhythmias were shorter in the experimental group. However, arterial blood pressure dipping was significant in the experimental group (23.67±10.89 mm Hg and p<0.001). CONCLUSION: Crataegus oxyacantha alcoholic extract produced an antiarrhythmic effect that was induced by digoxin in Wistar rats. However, in the clinical use of this extract, the hypotensive effect should be considered. Also, the alcoholic extract of Crataegus oxyacantha may be an alternative treatment medication for arrhythmias induced by digoxin toxicity in humans.

RESUMO

OBJECTIVE: To retrospectively examine the success and complication rates associated with image-guided percutaneous bone biopsy with a simulated Van Sonnenberg removable hub system. MATERIALS AND METHODS: During a 3.5-year period, 27 bone lesions at different anatomic locations with an indication for biopsy based on plain film, computed tomography (CT) and/or magnetic resonance imaging (MRI) findings were determined, and a total of 28 image-guided (fluoroscopy or CT) percutaneous biopsies were performed using a simulated Van Sonnenberg -removable hub system. This technique entailed the use of a cut-out Chiba needle hub that performed as a guide for the insertion of a larger needle. Either core and aspiration biopsy or core biopsy alone was utilized. RESULTS: The procedure yielded diagnostic material 89% of the cases (48% infection, 22% benign lesions, and 19% malignant lesions). Combined use of core and aspiration biopsy resulted in a higher diagnostic accuracy as compared to core biopsy alone. No false positive or false negative diagnoses were observed. No serious complications such as neurological deficits, bleeding, or organ injury were observed. CONCLUSION: The simulated Van Sonnenberg removable hub system provides a useful technique for percutaneous bone biopsies and is particulary suitable for deep seated (such as vertebral) lesions with its ability to facilitate the accessibility of the lesion with its built-in guidance needle. The procedure is safe in light of the literature data.

RESUMO

Blunt chest trauma and its associated complications represent a rare cause of cardiac arrest in a healthy child, although an increasing number of these events have been reported. Victims are most often diagnosed in ventricular fibrillation or tachycardia. However, cardiac conduction abnormalities are also reported. In this report, a healthy adolescent with supraventricular tachycardia associated with blunt chest trauma due to a football is presented. This is the first report in the literature of atrial arrhythmia in these cases with chest trauma.

RESUMO

BACKGROUND: Childhood obesity is a cardiovascular risk factor. OBJECTIVE: Epicardial adipose tissue (EAT) thickness, carotid intima-media thickness (IMT) and cardiac functions of obese children and their correlations were evaluated. SUBJECTS: Five hundred obese children and 150 age- and sex-matched healthy controls. METHODS: Anthropometric, laboratory data and echocardiographic measurements of IMT, EAT and cardiac functions were determined. RESULTS: Increased M-mode echocardiographic measurements, E/e' ratios, Tei index values and decreased E/A and e'/a' ratios (where E and A are early and late mitral/tricuspid diastolic velocities, respectively, and e' and a' are peak early diastolic and peak atrial systolic myocardial velocities, respectively), were determined in the obese group. Also, carotid artery IMT and EAT thickness were significantly higher in obese children. Carotid artery IMT, EAT thickness and left ventricular mass (LVM) were found to be strongly associated with Tei index values. CONCLUSION: Obesity is a major risk factor for cardiovascular diseases. In our study, we showed that obese children have early subclinical systolic and diastolic dysfunctions. Also, these cardiac impairments are correlated with the increase in IMT, EAT thickness and LVM.

RESUMO

OBJECTIVES: Obesity and hypertension are associated with structural and functional cardiac change in children and adults. The aim of the study is to evaluate the effect of hypertension and obesity on left ventricular geometric patterns and cardiac functions assessed by conventional and Doppler echocardiography. METHODS: Four hundred and thirty obese children, aged 6-17 years and 150 age and sex-matched healthy controls, were included in the study. Left ventricular geometry was classified as concentric hypertrophy, eccentric hypertrophy, concentric remodeling and normal geometry. RESULTS: Concentric hypertrophy group had the worst subclinical systolic and diastolic cardiac functions among all left ventricular geometric patterns. BMI and total adipose tissue mass are the predictors of abnormal ventricular geometry. Apart from the increase in carotid intima-media and epicardial adipose tissue thicknesses in different left ventricular geometry patterns, they are not predictable for abnormal geometry. CONCLUSION: The variety of alterations in cardiac function and morphology that has been observed in obese adults, appears to start earlier in life. Obesity and hypertension were clearly associated with the left ventricular geometry. Also, subclinical systolic and load-depended diastolic dysfunctions can be detected in obese hypertensive children with concentric hypertrophy.
