IntroductionHyperferritinemia is associated with increased mortality in pediatric sepsis, multiple organ dysfunction syndrome (MODS), and critical illness. The International Histiocyte Society has recommended that children with hyperferritinemia and secondary hemophagocytic lymphohistiocytosis (HLH) or macrophage activation syndrome (MAS) should be treated with the same immunosuppressant/cytotoxic therapies used to treat primary HLH. We hypothesized that patients with hyperferritinemia associated secondary HLH/sepsis/MODS/MAS can be successfully treated with a less immunosuppressant approach than is recommended for primary HLH.MethodsWe conducted a multi-center cohort study of children in Turkish Pediatric Intensive Care units with hyperferritinemia associated secondary HLH/sepsis/MODS/MAS treated with less immunosuppression (plasma exchange and intravenous immunoglobulin or methyl prednisolone) or with the primary HLH protocol (plasma exchange and dexamethasone or cyclosporine A and/or etoposide). The primary outcome assessed was hospital survival.ResultsTwenty-three children with hyperferritinemia and secondary HLH/sepsis/MODS/MAS were enrolled (median ferritin = 6341 μg/dL, median number of organ failures = 5). Univariate and multivariate analyses demonstrated that use of plasma exchange and methyl prednisolone or intravenous immunoglobulin (n = 17, survival 100%) was associated with improved survival compared to plasma exchange and dexamethasone and/or cyclosporine and/or etoposide (n = 6, survival 50%) (P = 0.002).ConclusionsChildren with hyperferritinemia and secondary HLH/sepsis/MODS/MAS can be successfully treated with plasma exchange, intravenous immunoglobulin, and methylprednisone. Randomized trials are required to evaluate if the HLH-94 protocol is helpful or harmful compared to this less immune suppressive and cytotoxic approach in this specific population.
Objective: To evaluate the accuracy of urine sample collection methods among children suspected of having urinary tract infections. Subjects and Methods: Four methods for urine sample collection were evaluated in 1,067 children aged 0–16 years with suspected urinary tract infections over 2 months at Dr. Sami Ulus Children’s Hospital. Within 30 min of collection, all specimens were sent to the laboratory, refrigerated and processed according to standard hospital microbiological procedures. Urine samples were analyzed using routine culture techniques. Results: At initial sending of the urine culture, 617 (57.8%) had negative culture results, 145 (13.6%) had positive culture results, and 305 (28.6%) had evidence of bacterial contamination. Clean catch specimens showed a contamination rate of 14.3% and urethral catheterization specimens showed a similar contamination rate (14.3%). However, urethral catheterization was preferred in only a small number of cases (n = 7). Suprapubic aspiration was also used in a small number of cases (n: 11) and the contamination rate for suprapubic aspiration was 9.1% (n: 1/11). The contamination rate for sterile urine bag was 43.9%, significantly higher than the other methods (p < 0.001). Conclusion: Suprapubic aspiration showed the lowest contamination rate and sterile urine bag showed the highest contamination rate among 4 methods of urine sample collection. Contaminated specimens, needed to be repeated and this procedure increased the cost of urine culture. In conclusion, measures should be taken to reduce the contamination rate in our center. This is an area where further investigation is required.
Parental education about 'fever in childhood' in our population may positively effect parental knowledge and approach to fever. However, parental education may not be effective in removing parental fear of fever in our population.
Severe disease and high mortality rates were seen in children with pandemic influenza. Death attributable to pandemic influenza occurred in all age groups of children with or without underlying illness. Multiple organ dysfunction syndrome is associated with increased mortality, and death is frequently secondary to severe lung infection caused by pandemic influenza.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
