Review Meta AnalysisAntibiotics for prolonged moist cough in children.
Cough is the most common symptom which presents to doctors. Chronic cough is reported in up to 9% of preschool aged children. American general practice guidelines suggest antimicrobial treatment may be indicated in children with cough lasting > 10 days. Questions concerning the benefits and harm of antibiotic treatment for prolonged cough in children need to be resolved. ⋯ Antibiotics are likely to be beneficial in the treatment of children with chronic moist cough. This evidence is however limited by study quality, study design and sensitivity analysis data. The use of antibiotics however has to be balanced against their well known adverse events. Further well-designed RCTs using valid cough outcome measures are needed to answer this question conclusively.

Because of concern that feedings may increase the risk of necrotizing enterocolitis, some high-risk infants have received prolonged periods of parenteral nutrition without enteral feedings. Providing trophic feedings (small volume feedings given at the same rate for at least 5 days) during this period of parenteral nutrition was developed as a strategy to enhance feeding tolerance and decrease time to reach full feedings. Whether trophic feedings result in better outcomes than initially withholding feedings or providing progressively increasing feedings can be established only in proper clinical trials. ⋯ In both comparisons, the group with the greater enteral intake (trophic feedings in the first comparison and advancing feedings in the second comparison) required significantly less time to reach full feedings and had a significant or near significant reduction in hospital stay. In both comparisons, the group with the greater intake also had a higher incidence of necrotizing enterocolitis although the difference was not statistically significant. The concern is greatest for the advancing feeding regimen. Even when trophic feedings were compared to no feedings, the relative risk for necrotizing enterocolitis was 1.16 (0.75 - 1.79), a finding consistent with a 16% increase in necrotizing enterocolitis and a number needed to harm of 50. A true increase of this magnitude might outweigh any short- or long-term benefits of trophic feedings. Moreover, the 95% confidence interval does not exclude the possibility that trophic feedings increase necrotizing enterocolitis by as much as 79% with a number needed to harm of 17. Whether no feedings, trophic feedings, or advancing feedings should initially be used is difficult to discern for a variety of reasons--the inherent difficulty of assessing enteral feedings in high-risk infants, the limited sample size and methodologic limitations of most studies to date, unexplained heterogeneity with respect to a number of outcomes, the potential for bias to affect the findings in unblinded studies, and the large number of infants who must be studied to assess the effect on necrotizing enterocolitis. One or more large, well designed, multi-center trials are needed to compare these approaches to early feeding with respect to important clinical outcomes. A conclusive evaluation would assess effects on not only the survival rate without necrotizing enterocolitis prior to discharge from the neonatal unit but also on the survival rate without severe gastrointestinal or neurodevelopmental disability at >= 18 months age.

Review Meta AnalysisPrevention and treatment of postpartum hypertension.
Postpartum blood pressure (BP) is highest three to six days after birth when most women have been discharged home. A significant rise in BP may be dangerous (e.g., lead to stroke), but there is little information about how to prevent or treat postpartum hypertension. ⋯ There are no reliable data to guide management of women who are hypertensive postpartum or at increased risk of becoming so. If a clinician feels that hypertension is severe enough to treat, the agent used should be based on his/her familiarity with the drug. Future studies of prevention or treatment of postpartum hypertension should include information about use of postpartum analgesics and outcomes of severe maternal hypertension, breastfeeding, hospital length of stay, and maternal satisfaction with care.

Corticosteroids continue to play a central role in induction of remission in active Crohn's disease. However, their use comes at a price of significant adverse effects when used repeatedly or for extended periods. Newer corticosteroid agents with limited systemic bioavailability offer a tantalizing option, if they can be shown to be efficacious and safer than conventional corticosteroids. Budesonide is the main alternative corticosteroid currently available in an enteric formulation. ⋯ With disease in the ileum or ascending colon, budesonide offers an effective therapy which is somewhat less efficacious but with fewer adverse effects than conventional corticosteroids (e.g. prednisone, prednisolone, or 6-methylprednisolone).

Review Meta AnalysisInhaled magnesium sulfate in the treatment of acute asthma.
Asthma exacerbations can be frequent and range in severity from relatively mild to status asthmaticus. The use of magnesium sulfate (MgSO4) is one of numerous treatment options available during acute exacerbations. While the efficacy of intravenous MgSO4 has been demonstrated, little is known about inhaled MgSO4. ⋯ Nebulised inhaled magnesium sulfate in addition to beta2-agonist in the treatment of an acute asthma exacerbation, appears to have benefits with respect to improved pulmonary function and there is a trend towards benefit in hospital admission. Heterogeneity between trials included in this review precludes a more definitive conclusion.
