Urinary Tract Infections in Low Birth Weight Neonates.

OBJECTIVE: Our objective was to evaluate the incidence of urinary tract infections (UTIs) in low birth weight (LBW) neonates and to evaluate the compliance of neonatal intensive care unit (NICU) providers in performing urine cultures as a part of late-onset sepsis (LOS) evaluations following an educational intervention. STUDY DESIGN: A retrospective chart review for all LBW infants undergoing LOS evaluations was performed. An educational intervention was conducted to encourage NICU providers to perform urine cultures in LOS evaluations. Prospective chart reviews were conducted following the intervention to assess compliance with the urine culture directive and the incidence of UTIs before and after the intervention. RESULTS: Rate of UTIs among LBW neonates was 1.3% for the entire study period and typical uropathogens were the cause. UTIs were found concurrently with bacteremia in only 33.3% of cases and showed a predilection for male infants when analyzing based on the number of infections. Urine cultures were performed in 20% of LOS evaluations prior to our educational intervention and increased to 57% (p < 0.0001) postintervention. CONCLUSION: An educational intervention is effective at increasing the rate of obtaining urine cultures with LOS evaluations. Performing these cultures reveals that UTIs in LBW neonates are common without bacteremia and can be missed if they are omitted from LOS evaluations. KEY POINTS: · UTIs occur often in preterm infants, especially boys.. · Education increases the performance of urine cultures.. · UTIs in preterm infants occur often without bacteremia..

Ketamine as an Adjunct for Treatment of Methotrexate-induced Neurotoxicity.

Methotrexate (MTX) is used in the treatment of several childhood cancers and is a main component of the treatment regimen for osteosarcoma. MTX has been linked with side effects of varying severity; headaches, nausea, emesis, lethargy, blurred vision, aphasia, hemiparesis, paresis, convulsions, leukoencephalopathy, and arachnoiditis are symptoms of MTX toxicity. MTX-induced neurotoxicity can occur in up to 15% of patients receiving high-dose MTX. The effects may be transient but can have life-threatening implications, sometimes requiring intubation for respiratory support and airway protection. Elevated homocysteine levels in the cerebrospinal fluid are documented in cases of MTX-induced neurotoxicity; dextromethorphan is used as an initial treatment for MTX-induced neurotoxicity as it works as a noncompetitive antagonist for the N-methyl D-aspartate receptors and suppresses homocysteine activity. In severe cases requiring intubation, medications for sedation are utilized. Ketamine is also an N-methyl D-aspartate receptor antagonist, and as such, may be considered as an optimal treatment choice when sedation is required. We describe the use of ketamine in a pediatric patient with MTX-induced neurotoxicity. The use of ketamine in the treatment of MTX-induced neurotoxicity has not been described in the literature.

Towards Guideline-Based Management of Tethered Cord Syndrome in Spina Bifida: A Global Health Paradigm Shift in the Era of Prenatal Surgery.

An estimated 60% of the world's population lives in Asia, where the incidence of neural tube defects is high. Aware that tethered cord syndrome (TCS) is an important comorbidity, the purpose of this systematic review was to explore the treatment of TCS among individuals living with spina bifida (SB) in Asia. MEDLINE and Embase databases were searched for relevant studies published from January 2000 to June 2018. Search terms such as 'spinal dysraphism,' 'spinabifida,' 'diastematomyelia,' 'lipomeningocele,' 'lypomyelomeningocele,' 'meningomyelocele,' and 'tethered cord syndrome' were used in diverse combinations. Of the 1,290 articles that were identified in accordance with PRISMA (Preferred Items for Systematic Reviews and Meta-Analyses) guidelines, 15 Asia-based studies met the inclusion criteria. Significant differences in the diagnostic criteria and management of TCS were documented. As the surgical techniques for prenatal closure of the spinal defect continue to evolve, their adoption internationally is likely to continue. In this setting, a clear and evidence-based approach to the definition and management of TCS is essential. The recent publication by the Spina Bifida Association of America of their updated care guidelines may serve as a tool used to promote a systematized approach to diagnosing and treating TCS among individuals with SB in the region, as well as globally.
