Cystic echinococcosis (CE) is one of the most important zoonotic diseases in a wide geographic area, including Turkey. In the present project, a total of 4275 students from Celal Bayar University, Manisa, Turkey, were screened by ultrasonography (US) and specific antibodies for CE were examined by Western blotting (WB) and ELISA in finger prick blood samples of 2034 of 4275 volunteered students. We aimed to report the apparent prevalence of CE based on different diagnostic procedures and to compare WB and ELISA with US in diagnosis of CE in a mass screening setting. Six new cases were diagnosed as CE by US during the survey. In addition to these cases, three students were also detected to have been previously operated and pathologically confirmed for hepatic CE. US revealed parenchymal changes in these cases in concordance with their operation history; so, the prevalence of CE by US was calculated as 0.21% (9/4275) (95%CI, 0.11-0.39%) among university students in Manisa. Bands were detected at 8, 28, 32, 38, 42, 47, 70 and 90kDa by WB and the cases were considered to be positive for CE when at least three of the bands were seen together. Apparent prevalence of CE by ELISA and WB were found to be 2.11% (43/2034) (95%CI, 1.57-2.83%) and 0.25% (5/2034) (95%CI, 0.10-0.57%), respectively. Of the six US positive cases, WB was positive in only one case with two cysts in the liver. All of four cases with liver involvement were positive by ELISA. The high prevalence of CE among university students in Manisa indicated that CE is a major health problem in this area of Turkey. Our results supported that WB is rather difficult and not feasible as a mass screening test and may not be effective for confirmation especially in asymptomatic cases. As a result, we recommend US to be used initially in mass screening surveys for CE followed by confirmation by ELISA for suspected cases. Further examination primarily by chest X-ray followed by computed tomography and/or magnetic resonance imaging, if needed, should be recommended for US negative, ELISA and WB positive individuals who may have non-abdominal cysts.

BACKGROUND Hypoxic ischemic encephalopathy may result in many neurological deficits. It is crucial to make early diagnosis and assess the prognosis correctly. AIMS We aimed to determine the factors to evaluate the prognosis of hypoxic ischemic encephalopathy. METHODS Electroencephalography, neuroimaging, periodic neurological exams and a developmental test at 44-48 months after discharge from the hospital were performed on twenty five term newborn infants with clinical evidence of hypoxic ischemic encephalopathy. RESULTS Normal/mildly abnormal neonatal electroencephalography correlated with favorable outcome, particularly if neuroimaging was normal. The cranial MRI sensitivity was 83.3%, while the specificity was 57.9%, the positive predictive value was 38.5%, and the negative predictive value was 91.6%. Moderate/severely abnormal electroencephalography and multifocal/diffuse cortical or deep gray matter lesions correlated with poor outcome. CONCLUSIONS Newborn infants with hypoxic ischemic encephalopathy should be treated in neonatal intensive care units, assessed with periodic neurological examination, electroencephalogram and brain imaging. This would help to initiate early intervention and improve the outcome of patients.

Blau syndrome is a rare, multisystem, autosomal-dominant, and granulomatous disorder caused by susceptibility variants in the NOD2 gene. We describe here a 14-year-old girl with Blau syndrome with incidentally diagnosed renal carcinoma. The index case presented with growth retardation and recurrent symmetric arthritis. Her clinical symptoms included bilateral cataract due to recurrent uveitis, camptodactyly, and persistent erythematous rash with ichthyosis. Her two sisters and her mother were affected with combinations of these conditions—symmetric polyarthritis, uveitis, and skin involvement—suggesting an autosomal dominant trait. The index case developed a chronic renal insufficiency, and an abdominal computerized tomography scan revealed a 2.5-cm mass in the left kidney. The histopathological examination showed renal clear cell carcinoma, chronic tubulointerstitial nephritis, and giant cell granulomas in both the tumor and non-neoplastic renal tissue. Granulomatous inflammation was observed in the skin biopsy specimen. The patient was diagnosed with Blau syndrome based on her family history, uveitis, granulomatous inflammation proved by skin biopsy, and polyarthritis. Sequencing of the NOD2 gene showed a heterozygous p.R334Q mutation in all affected family members. To the best of our knowledge, this is the first reported case of a patient with Blau syndrome accompanied by chronic renal failure and renal carcinoma.

SUMMARY OBJECTIVE Aims of this study were to compare serum leptin levels, atherosclerotic markers and carotid intima media thickness (IMT) among the overweight, obese and normal weight healthy adolescents and to investigate the association of carotid IMT with leptin and atherosclerotic markers in adolescence. METHODS Seventy obese-overweight adolescents (27 of them obese, 43 of them overweight) and 72 two normal weight adolescents aged 14-18 years were included in this study. Leptin and homocysteine levels and lipid profiles were determined and carotid IMT were measured in all adolescents. Subjects were evaluated as obese-overweight and normal weight and obese, overweight and normal weight. RESULTS Carotid IMT was significantly different among the overweight adolescents, obese adolescents and the control group (p < 0.001). Leptin levels were significantly higher in obese-overweight adolescents compared to the control group (p < 0.001). Apolipoprotein (Apo) B levels were significantly higher in obese adolescents than the overweight ones and the control group (p < 0.016). There were significantly positive correlations of carotid IMT with leptin, homocysteine and Apo B levels (p < 0.05, r = 0.33, 0.28, 021, respectively). The factors associated with carotid IMT were leptin and ApoB levels (β = 0.632, p < 0.04, β = 0.264, p = 0.019, respectively). CONCLUSION Subclinical atherosclerosis determined by carotid IMT begins in overweight adolescents. Elevated leptin and Apo B levels are independent predictors of subclinical atherosclerosis. Leptin resistance, which is related to subclinical atherosclerosis, also begins in overweight adolescents. High Apo B levels, which promote development of atherosclerosis are more prominent in obese adolescents than other groups. For these reasons, all necessary precautions should be taken in overweight adolescents to prevent atherosclerosis as well as in obese adolescents.

Childhood constrictive bronchiolitis obliterans (CBO) is characterized clinically by the persistence of obstructive respiratory symptoms following a prolonged episode of lower respiratory viral infection. The diagnosis depends on the clinical, radiological and laboratory findings. Perfusion defects on scintigraphy may predict the severity. This report describes a 2‐year‐old girl who presented with a 15‐day history of respiratory distress despite treatment. Auscultation of the lungs revealed prolonged expiration and bilateral crepitant rales. CXR revealed bilateral paracardiac infiltration. She improved with a treatment regimen of bronchodilators, systemic steroids and antibiotherapy; however, rales were detected again 10 days after discharge. HRCT of the lung revealed an oligaemic‐mosaic pattern, more prominent in the left lung. The diagnosis of CBO was made on the basis of these clinical and radiological findings. Perfusion was normal in the right lung but diffusely decreased in the left lung on perfusion scintigraphy by Tc99m‐MAA. Magnetic resonance (MR) angiography source images of the lungs revealed significant but not diffuse perfusion defects in the left lung, in contrast to radionuclide scintigraphy. There were areas of low perfusion in the right lung, which were not evident in radionuclide scintigraphy. The use of source images of MRI angiography of the lungs may be more sensitive and specific for the detection of perfusion defects in patients with CBO and may assist in determining the prognosis.

Simple predictors are needed for the screening of nonalcoholic fatty liver disease (NAFLD) in obese children. We aimed to assess the role of anthropometric parameters in the prediction of NAFLD. Three hundred and thirty two obese children (152 male, 180 female) aged 4.6-17.0 years were included in this study. Weight, height, waist (WC), and hip circumference were measured. Body mass index (BMI), waist-hip-ratio (WHR), and waist-height-ratio (WHtR) were calculated. Obesity was defined as BMI for age and sex ≥ 95th percentile. NAFLD was diagnosed using ultrasonography (US). NAFLD was present in 60.8% of obese children. Fatty liver prevalence differed significantly by gender and puberty (55.0% of girls vs 67.7% of boys, and 28.7% in prepubertal vs 71.3% in pubertal children; p < 0.05). Significantly higher BMI, BMI standard deviation score (SDS), WC, and WHtR were found in obese children with NAFLD compared to obese children without NAFLD (p < 0.05). Only WHtR was found to be an independent predictor for NAFLD in a logistic regression analysis (p < 0.001, B:1.096, 95% CI 1.047-1.148). Fatty liver is common among obese children, particularly in obese boys. WHtR is a simple and easy index for predicting of NAFLD in obese children and can be used for mass screening in public health.

Abstract Our aim is to determine the rational usage of imaging techniques in order to prevent or minimize permanent renal damage in recurrent urinary tract infections (UTIs). This study was enrolled children aged between 2 and 36 months, following-up with the diagnosis of recurrent UTI. All children had ultrasonography (USG) and dimercaptosuccinic acid scanning, 39 of them had underwent on voiding cystourethrography. There were 133 children (87 girls, 46 boys) with the mean age of 32.82 ± 38.10 months included into the study. Forty-three kidney units were normal in ultrasonogram of which seven units had reflux whereas among 35 units with hydronephrosis 22 units had reflux. Sensitivity and specificity presence of hydronephrosis in ultrasonogram for prediction of reflux was 75.9% and 73.5%, respectively. There were 19 dilated ureters in ultrasonogram, and among them 14 had reflux. Sensitivity and specificity of presence with ureteral dilatation in ultrasonogram for prediction of reflux was found as 48.3% and 89.8%, respectively. The sensitivity of parenchymal thinning seen in ultrasonogram for the evaluation of renal parenchyma was 15.9%, whereas specificity was 98.2% .Sensitivity and specificity of dimercaptosuccinic acid for prediction of reflux was 51.6% and 72.3%, respectively. The normal ultrasonogram findings cannot rule out neither possibility of reflux presence nor development of renal scarring. Therefore, DMSA scanning has major role both in determination of parenchymal damage and prevention of scarring. Also we get an important result as ureteral dilatation seen in USG, related to presence of reflux.

Aims: We aimed to evaluate asymmetric dimethylarginine levels in young patients with Type 1 diabetes mellitus according to diabetes duration and to examine the relationship between these levels and measures of atherosclerosis and myocardial function. Materials and methods: In total, 83 patients (8.5–22 years) with Type 1 diabetes mellitus were stratified by diabetes duration: 12–60 months (Group 1, n = 27), >60–120 months (Group 2, n = 29) and >120 months (Group 3, n = 27). Asymmetric dimethylarginine levels were assessed. Carotid intima–media thickness was measured. Myocardial function was assessed by M-mode, conventional Doppler and tissue Doppler echocardiography. Results: Asymmetric dimethylarginine level was significantly higher in Group 1, while carotid intima–media thickness was significantly greater in Group 3 (p < 0.05). Tissue Doppler echocardiography showed the ratio of peak early to peak late diastolic myocardial annular velocity decreased significantly in Groups 2 and 3 with a negative correlation with duration (r: −0.310, p = 0.004) and HBA1c levels (r = −0.391, p < 0.001). Myocardial performance index in all groups and isovolumic relaxation time in Group 3 increased significantly. Asymmetric dimethylarginine levels were negatively correlated with carotid intima–media thickness and isovolumic relaxation time (p < 0.05). Conclusion: In contrast to adult diabetics, asymmetric dimethylarginine concentration decreases as diabetes duration increases in young Type 1 diabetic patients and is associated with worsening measures of cardiovascular risk and poorer diastolic function.

Purpose: In this study we aimed to evaluate the radiological examinations of the pediatric patients who were operated with initial diagnosis of acute abdomen. Methods: We retrospectively reviewed the clinical records and imaging findings of 252 children. All patients were evaluated by plain abdominal radiographs (PAX) and ultrasonography (US). Only 10 patients were examined using computed tomography (CT). The findings of the PAX, US and CT of each patient were determined from their detailed archive records according to their clinical diagnosis. Results: The most frequent pathology was appendicitis in our study whereas the other pathologies were invagination, ovarian torsion, the complications of Meckel’s diverticulum, gastrointestinal obstruction and tuboovarian abscess in decreasing frequency. PAXs were valuable in diagnosis of the patients with ileus. It has been showed that US was the most useful for patients with appendicitis and invagination. CT was performed only in 4% of our cases as an advanced diagnostic method. Conclusion: The pediatric patients with acute abdomen have been evaluated radiologically by PAX and US routinely and frequently. CT was performed as an advanced diagnostic method very rarely. CT would be utilized to a lower extent as a more advanced method of imaging in unsolved patient group, as US and PAX solve the pediatric acute abdominal pathologies in high percentages.
