Review Meta AnalysisLow molecular weight heparin for prevention of venous thromboembolism in patients with lower-leg immobilization.
Immobilization of the lower leg is associated with venous thromboembolism. Low molecular weight heparin (LMWH) is an anticoagulant treatment which might be used in adult patients with lower-leg immobilization to prevent deep venous thrombosis and its complications. ⋯ Use of LMWH in outpatients significantly reduces VTE when immobilization of the lower leg is required.

Review Meta AnalysisAbsorbent products for moderate-heavy urinary and/or faecal incontinence in women and men.
Incontinence is a common and embarrassing problem which has a profound effect on social and psychological well-being. Many people wear absorbent products to contain urine and/or faeces and protect their clothes and dignity. Users of absorbent pads are very diverse, including younger women, particularly those who have had children, older men with prostate disease, people with neurological conditions and older people with mobility and mental impairment. Whilst small absorbent pads for light incontinence are adequate for some users with low volumes of urine loss, for others with higher volumes more absorbent products are needed. A practical definition of moderate-heavy incontinence is urine or faecal loss that requires a large absorbent pad (typically with a total absorbent capacity of 2000 g to 3000 g) for containment. ⋯ Although data were available from only two eligible trials the data were sufficiently robust to make some recommendations for practice. There is evidence that different designs are better for men and women. Diapers are the most cost-effective disposable design for men. Disposable pull-ups are most preferred for women but are expensive: disposable inserts are a cheaper alternative (except in nursing homes where diapers are preferred to inserts at night). Washable diapers are the cheapest design but have limited acceptability, confined mainly to some men at night. There were not enough people in the trials to draw any conclusions about which designs are best for faecal incontinence and no particular design seemed to be better or worse for skin health. People have different preferences for absorbent product designs and using a combination (different designs for day/night, going out/staying in) may be more effective and less expensive than using one design all the time.

Review Meta AnalysisCaudal epidural block versus other methods of postoperative pain relief for circumcision in boys.
Techniques to minimize the postoperative discomfort of penile surgery, such as circumcision, include caudal block; penile block; systemic opioids and topical local anaesthetic cream, emulsion or gel. ⋯ Differences in the need for rescue or other analgesia could not be detected between caudal, parenteral and penile block methods. In day-case surgery, penile block may be preferable to caudal block in children old enough to walk due to the possibility of temporary leg weakness after caudal block. Evidence from trials is limited by small numbers and poor methodology. There is a need for properly designed trials comparing caudal epidural block with other methods such as morphine, simple analgesics and topical local anaesthetic creams, emulsions or gels.

Review Meta AnalysisInterval debulking surgery for advanced epithelial ovarian cancer.
Primary debulking surgery, a crucial step in the management of epithelial ovarian cancer, is not always possible in patients with advanced stage disease (stage III to IV). In some circumstances, surgery may have been attempted but generally does not yield good results with residual tumour masses > 1 to 2 cm (so called suboptimal surgery). Induction or neoadjuvant chemotherapy followed by interval debulking surgery (IDS) may have an alternative role in this setting. However, the advantage of IDS compared to conventional methods is still a controversial issue. ⋯ No conclusive evidence was found to determine whether IDS between cycles of chemotherapy would improve or decrease the survival of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy. IDS appeared to yield benefit only in the patients whose primary surgery was not performed by gynecologic oncologists. Data on QOL and adverse events were inconclusive.

Review Meta AnalysisGalactomannan detection for invasive aspergillosis in immunocompromized patients.
Invasive aspergillosis (IA) is the most common life-threatening opportunistic invasive mycosis in immunocompromized patients. A test for IA needs to be not too invasive and not too big a burden for the already weakened patient. The serum galactomannan ELISA seems to have potential for both requirements. ⋯ At a cut-off value 0.5 ODI in a population of 100 patients with a disease prevalence of 8% (overall median prevalence), 2 patients who have IA, will be missed (sensitivity 78%, 22% false negatives), and 17 patients will be treated or further referred unnecessarily (specificity of 81%, 19% false negatives). If we use the test at cut-off value 1.5 in the same population, that will mean that 3 IA patients will be missed (sensitivity 64%, 36% false negatives) and 5 patients will be treated or referred unnecessarily (specificity of 95%, 5% false negatives). These numbers should however be interpreted with caution, because the results were very heterogeneous.
