Pediatric posterior reversible encephalopathy syndrome: Age related clinico-radiological profile and neurologic outcomes.

BACKGROUND: The aim of this study was to analyze the characteristics of pediatric posterior reversible encephalopathy syndrome (PRES) to determine clinical and radiologic differences between younger and older age groups, and to identify risk factors for development of any neurologic sequelae. METHODS: The study cohort consisted of confirmed pediatric PRES patients in a tertiary care university hospital from January, 2015, to December, 2020. Demographic and clinical properties, radiological manifestations, and neurologic outcomes were noted. Children aged ≤6 years were compared with those older than 6 years and factors affecting neurologic outcomes were evaluated. RESULTS: The most common underlying diseases were oncological (37%) and kidney diseases (29%). Epileptic seizures were the most frequent symptoms at initial clinical presentation. The regions in the brain that were most commonly involved were the occipital region (n = 65, 96%), the parietal region (n = 52, 77%), and the frontal lobe (n = 35, 54%). Magnetic resonance imaging (MRI) findings were consistent with atypical patterns in most of the study cohort (71%). Patients with unfavorable clinical outcomes (n = 13, 19.1%) had longer initial seizure times and longer encephalopathy times, lower leucocyte and absolute neutrophil counts, and lower neutrophil to lymphocyte ratios. No relationship was found between MRI findings, involvement patterns, and neurologic outcomes. CONCLUSIONS: No clinically specific differences between two different age groups were found. Atypical imaging manifestations of pediatric PRES in our study had an incidence that was as high as those found in earlier adult studies. Multivariate logistic regression analysis showed that the initial neutrophil to lymphocyte ratio, absolute neutrophil counts, and white cell counts could not predict poor neurologic outcomes.

Central Venous Catheter Insertion for Vascular Access: A 6-year Single-center Experience.

Background: Central venous catheterization is performed for such reasons as hemodynamic monitoring, parenteral nutrition, drug and fluid administration, and extracorporeal treatment. This study aimed to retrospectively review the indications for central venous catheter (CVC) insertion for vascular access and removal by pediatric intensive care unit (PICU) physicians, catheter types, and catheter-associated complications. Materials and methods: The indications for CVC insertion and removal, catheter insertion site, types of catheters, catheter-associated complications, whether or not insertion was ultrasonographically guided, catheter-associated infections, and duration of use of 1200 catheters used by PICU physicians between 2015 and 2020 were retrospectively reviewed. Results: In all, 315 (26.3%) hemodialysis catheters and 885 (73.8%) CVCs were inserted. Mean duration of catheter use was 12.33 ± 7.28 days. CVCs were inserted most commonly (28.4% [n = 341]) based on the indication of multiple drug infusions. In total, 44.8% of the CVCs were inserted under ultrasonographic guidance. The most common reason for the removal of catheters was that they were no longer needed (76.8% [n = 921]). Catheter-associated bloodstream infection occurred at the rate of 5.5 days per 1000 catheter days. Conclusion: Central venous catheterization is becoming more widespread because of the benefits it provides during the follow-up and treatment of children. As central venous catheterization is a more invasive procedure than peripheral localization and is associated with severe complications, especially in pediatric patients, it should be carefully performed under sterile conditions and by experienced personnel based on appropriate indications. Central venous catheters should be removed as soon as the need disappears. How to cite this article: Misirlioglu M, Yildizdas D, Yavas DP, Ekinci F, Horoz OO, Yontem A.

Clinical predictive value of the urine leukocyte esterase test positivity in childhood.

BACKGROUND: False negative or positive results may occur in the urine dipstick test for leukocyte esterase (LE), which is used to determine urinary tract infection (UTI). We aimed to investigate the clinical importance of the presence or absence of pyuria in urine sediment for diagnosing UTI in the presence of positive LE in dipstick analysis. METHODS: Patients admitted to the pediatric nephrology outpatient clinic with positive urine LE tests were divided into two groups: those without pyuria (Group 1) and those with pyuria (Group 2) in their urine sediment. Hospital files of the patients were evaluated retrospectively for demographic variables, lower or upper UTI symptoms, physical examination for phimosis and vulvovaginitis, urinalysis for LE and nitrite tests, urine sediment microscopy, urine culture, complete blood count and C-reactive protein. Both groups were compared for the significant growth of pathogenic bacteria in urine cultures along with clinical and laboratory parameters. RESULTS: Among 578 children giving samples for urinalysis, there were 287 cases with positive LE tests. Groups 1 and 2 included 123 and 164 cases, respectively. The proportion of girls was higher in Group 1 and vulvovaginitis rate was higher among the girls in Group 1. Girls with vulvovaginitis were mostly prepubertal. Upper UTI symptoms, significant pathogen growth rate, and elevated acute phase response were more common in Group 2. In addition, the phimosis rate was more common among the boys in Group 1 with false positive LE test. CONCLUSIONS: Children with positive LE tests without pyuria are mostly prepubertal girls and there is a high rate of vulvovaginitis in these girls. Unnecessary tests and treatments for UTI may be avoided with detailed history and physical examination in prepubertal girls who have a false positive LE test. We also found, for the first time, that a false positive LE test is significantly associated with phimosis in boys.
