Review Meta AnalysisQuantitative versus qualitative cultures of respiratory secretions for clinical outcomes in patients with ventilator-associated pneumonia.
Ventilator-associated pneumonia (VAP) is a common infectious disease in intensive care units (ICUs). The best diagnostic approach to resolve this condition remains uncertain. ⋯ There is no evidence that the use of quantitative cultures of respiratory secretions results in reduced mortality, reduced time in ICU and on mechanical ventilation, or higher rates of antibiotic change when compared to qualitative cultures in patients with VAP. Similar results were observed when invasive strategies were compared with non-invasive strategies.

Review Meta AnalysisLate erythropoietin for preventing red blood cell transfusion in preterm and/or low birth weight infants.
Low plasma levels of erythropoietin (EPO) in preterm infants provide a rationale for the use of EPO to prevent or treat anaemia. ⋯ Late administration of EPO reduces the use of one or more RBC transfusions, the number of RBC transfusions per infant but not the total volume of RBCs transfused per infant. Any donor exposure is likely not avoided as most studies included infants who had received RBC transfusions prior to trial entry. Late EPO does not significantly reduce or increase any clinically important adverse outcomes. Further research of the use of late EPO treatment to prevent donor exposure is not indicated. Research efforts should focus on limiting donor exposure during the first few days of life in sick neonates, when RBC requirements are most likely to be required and cannot be prevented by late EPO treatment.

Review Meta AnalysisBotulinum toxin for the treatment of strabismus.
The use of botulinum toxin as an investigative and treatment modality for strabismus is well reported in the medical literature. However it is unclear how effective its use is in comparison to other treatment options for strabismus. ⋯ The majority of published literature on the use of botulinum toxin in the treatment of strabismus consists of retrospective studies, cohort studies or case reviews. Although these provide useful descriptive information, clarification is required as to the effective use of botulinum toxin as an independent treatment modality. Four RCTs on the therapeutic use of botulinum toxin in strabismus have shown varying responses ranging from a lack of evidence for prophylactic effect of botulinum toxin in acute sixth nerve palsy, to poor response in patients with horizontal strabismus without binocular vision, to no difference in response in patients that required retreatment for acquired esotropia or infantile esotropia. It was not possible to establish dose effect information. Complication rates for use of Botox™ or Dysport™ ranged from 24% to 55.54%.

Review Meta AnalysisIntra-uterine insemination for unexplained subfertility.
Intra-uterine insemination (IUI) is a widely used fertility treatment for couples with unexplained subfertility. Although IUI is less invasive and less expensive than in vitro fertilisation (IVF), the safety of IUI in combination with ovarian hyperstimulation (OH) is debated. The main concern about IUI treatment with OH is the increase in multiple pregnancy rate. ⋯ There is evidence that IUI with OH increases the live birth rate compared to IUI alone. The likelihood of pregnancy was also increased for treatment with IUI compared to TI in stimulated cycles. One adequately powered multicentre trial showed no evidence of effect of IUI in natural cycles compared with expectant management. There is insufficient data on multiple pregnancies and other adverse events for treatment with OH. Therefore couples should be fully informed about the risks of IUI and OH as well as alternative treatment options.

Review Meta AnalysisOrbital radiotherapy for adult thyroid eye disease.
Thyroid eye disease is an autoimmune inflammatory condition of the orbital and periorbital tissues. Orbital radiotherapy is an anti-inflammatory treatment used in the treatment of active thyroid eye disease. It is administered as an outpatient procedure in 10 to 12 fractionated doses. ⋯ This review found that orbital radiotherapy is more effective than sham radiotherapy for the treatment of mild-to-moderate thyroid eye disease. In a single trial no difference between radiotherapy and steroid monotherapy was found. A meta-analysis of our secondary outcome of disease severity was not possible but results from individual trials suggest a better outcome with combination treatment with steroids versus steroids alone. No significant changes in quality-of-life scores following treatment with radiotherapy versus alternative treatments were found. Short-term adverse events related to radiotherapy that were reported were local and mild but long-term data were lacking and development of retinal changes following radiotherapy was not reported on.
