ReviewInternal fixation implants for intracapsular proximal femoral fractures in adults.
Numerous different implants with screws, pins and side plates have been used for the internal fixation of intracapsular hip fractures. ⋯ No clear conclusions can be made on the choice of implant for internal fixation of intracapsular fractures from the available evidence within randomised trials.

There have been many randomised trials of adjuvant tamoxifen among women with early breast cancer, and an updated overview of their results is presented. ⋯ For women with tumours that have been reliably shown to be ER-negative, adjuvant tamoxifen remains a matter for research. However, some years of adjuvant tamoxifen treatment substantially improves the 10-year survival of women with ER-positive tumours and of women whose tumours are of unknown ER status, with the proportional reductions in breast cancer recurrence and in mortality appearing to be largely unaffected by other patient characteristics or treatments.

ReviewRemoval of nail polish and finger rings to prevent surgical infection.
Surgical wound infection may be caused by transfer of bacteria from the hands of the surgical team during operative procedures. Careful surgical scrubbing is therefore performed to reduce the number of bacteria on the skin. The wearing of finger rings and nail polish is thought to reduce the efficacy of the scrub as they are thought to harbour bacteria in microscopic imperfections of nail polish and on the skin beneath finger rings. ⋯ There is no evidence of the effect of removing nail polish or finger rings on the rate of surgical wound infection. There is insufficient evidence of the effect of wearing nail polish on the number of bacteria on the skin. However, the one trial making this comparison trial was too small to exclude anything other than a very large difference in the number of bacteria on the skin.

Hepatitis B virus infection is a serious health problem worldwide. Traditional Chinese medicinal herbs have been widely used to treat chronic liver diseases, and many controlled trials have been done to investigate their efficacy. ⋯ Some Chinese medicinal herbs may work in chronic hepatitis B. However, the evidence is too weak to recommend any single herb. Rigorously designed, randomised, double-blind, placebo-controlled trials are required.

ReviewBisphosphonates for osteoporosis in people with cystic fibrosis.
Osteoporosis is a disorder of bone mineralization that can lead to reduced bone mineral density and an increased risk for fractures. It is found in about one third of adults with cystic fibrosis. Bisphosphonates have been shown to increase bone mineral density and decrease the risk of new fractures in post-menopausal women and in patients receiving long-term oral corticosteroids. ⋯ Intravenous pamidronate increases bone mineral density at axial sites in people with cystic fibrosis, although it can cause severe bone pain in patients not receiving corticosteroids. Additional studies in larger populations are needed to determine the effect on fracture rate and survival.
