Meta AnalysisRisk factors for seizure recurrence in children with febrile seizures: a pooled analysis of individual patient data from five studies.
To reassess the relations between postulated risk factors and seizure recurrence after a first febrile seizure (FS), the individual data from five follow-up studies that used similar definitions of FSs and risk factors were pooled and reanalyzed. The risk of frequent recurrent seizures and of the occurrence of complex seizures in previously healthy, untreated children was studied. Seizure recurrence hazard was described as a function of the child's attained age. ⋯ Young age at onset (< 12 months), a family history of unprovoked seizures, and a partial initial FS were all associated with an increased risk of complex seizures. A higher recurrence rate in clinic-based studies compared with population-based studies could not be explained by a difference in the presence of the risk factors studied. Thus other factors must influence seizure recurrence after an initial FS.

Meta Analysis
The role of selective digestive tract decontamination on mortality and respiratory tract infections. A meta-analysis.
To review available clinical trials of selective digestive decontamination (SDD) in patients requiring intensive care. ⋯ These results suggest that SDD decreases the overall incidence of acquired pneumonia and tracheobronchitis in patients requiring intensive care. SDD had no apparent effect on the hospital mortality rate. The routine use of SDD cannot be supported by this meta-analysis. SDD may be useful in specific circumstances where a particular ICU or ICU population is found to have an excessive incidence of acquired infections. Any use of SDD should include careful patient surveillance for the emergence of infection due to bacteria not covered by the prophylaxis regimen and due to antibiotic-resistant bacteria.

Meta Analysis
Efficacy of BCG vaccine in the prevention of tuberculosis. Meta-analysis of the published literature.
To quantify the efficacy of BCG vaccine against tuberculosis (TB). ⋯ On average, BCG vaccine significantly reduces the risk of TB by 50%. Protection is observed across many populations, study designs, and forms of TB. Age at vaccination did not enhance predictiveness of BCG efficacy. Protection against tuberculous death, meningitis, and disseminated disease is higher than for total TB cases, although this result may reflect reduced error in disease classification rather than greater BCG efficacy.

Meta Analysis Comparative StudyA meta-analysis of the therapeutic role of oil soluble contrast media at hysterosalpingography: a surprising result?
To evaluate the therapeutic effect of oil-soluble contrast media compared with water-soluble contrast media after hysterosalpingography (HSG) in infertile couples. ⋯ Oil-soluble contrast media have a therapeutic effect compared with water-soluble media and this effect is greatest for patients who have been diagnosed as having unexplained infertility. New techniques for the evaluation of tubal patency support the hypothesis that tubal "plugs" may be involved in proximal tubal blockage.

Meta Analysis
Antibiotics to prevent infection in patients with dog bite wounds: a meta-analysis of randomized trials.
To determine whether prophylactic antibiotics prevent infection in patients with dog bite wounds. ⋯ Prophylactic antibiotics reduce the incidence of infection in patients with dog bite wounds. The full costs and benefits of antibiotics in this situation are not known. It may be reasonable to limit prophylactic antibiotics to patients with wounds that are at high risk for infection.
