Use of leukotriene receptor antagonists are associated with a similar risk of asthma exacerbations as inhaled corticosteroids.
The researchers compared the effectiveness of different controller medication regimens under real-life conditions. They found that the risk of emergency department visits, hospitalizations, and oral corticosteroids did not differ between children who initiated leukotriene antagonist and those who initiated inhaled corticosteroid. These findings may be explainable by leukotriene antagonist having similar effectiveness as inhaled corticosteroid in real-life usage.

Comparative effectiveness of senna to prevent problematic constipation in pediatric oncology patients receiving opioids: a multicenter study of clinically detailed administrative data.
The researcher investigated senna’s effectiveness, compared with other prophylactic oral bowel medications, in reducing opioid-induced constipation in pediatric cancer patients. They found that initiating senna therapy within two days of starting opioids, compared with initiating another oral bowel medication, was significantly associated with a lower risk of problematic constipation.

Direct, indirect, total, and overall effectiveness of the rotavirus vaccines for the prevention of gastroenteritis hospitalizations in privately insured US children, 2007-2010.
This study demonstrated how direct, indirect, total, and overall effectiveness estimates and absolute benefits of rotavirus vaccines vary through the years following vaccine introduction. It found that direct effectiveness of 1 or more doses of rotavirus vaccine in preventing rotavirus gastroenteritis hospitalizations ranged from 87 to 92 percent each year.

Progressive multifocal leukoencephalopathy in pediatric patients: case report and literature review.
Progressive multifocal leukoencephalopathy is a rare, demyelinating disease of the central nervous system caused by JC virus. Fewer than 30 cases have been reported in HIV- and non-infected children. The researchers report the case of a 15-year-old girl with progressive multifocal leukoencephalopathy and AIDS who presented with nystagmus, dysarthria and ataxia. They also include a literature review.

A comparison of confounding adjustment methods for assessment of asthma controller medication effectiveness.
Using three confounding adjustment procedures—covariate-adjusted regression, propensity score regression, and high-dimemsional propensity score regression—on a population of 24,680 children with asthma, researchers found that patients treated with leukotriene antagonists were no more likely than those treated with inhaled corticosteroids to experience adverse outcomes.
