ReviewRecombinant Factor VIIa concentrate versus plasma derived concentrates for the treatment of acute bleeding episodes in people with Haemophilia A and inhibitors.
In some people with haemophilia, therapeutic clotting agents are recognised as a foreign protein and anti-FVIII antibodies, known as 'inhibitors', are produced. This review investigates which treatment most effectively arrests acute bleeding in people with haemophilia A and inhibitors. ⋯ No RCTs on the relative effectiveness of Recombinant FVIIa concentrate compared to human plasma-derived concentrates in people with haemophilia A and inhibitors were identified for inclusion in this review. The research evidence on which to base clinical decisions is therefore limited to case reports, and other less robust evidence. There is need for a well-designed, adequately-powered randomised controlled trial to assess the relative benefits and risks of using Recombinant FVIIa concentrate compared to human plasma-derived concentrates in people with haemophilia A and inhibitors.

ReviewInhaled anti-cholinergics for prolonged non-specific cough in children.
Non-specific cough is defined as non-productive cough in the absence of identifiable respiratory disease or known aetiology. It is commonly seen in paediatric practice. These children are treated with a variety of therapies including inhaled anti-cholinergic medications. ⋯ There is currently no evidence to support the use of inhaled anti-cholinergics for symptomatic control of non-specific cough in children. Further research examining the effects of this intervention is needed.

Anticholinergic agents such as ipratropium bromide are sometimes used in the treatment of chronic asthma. They effect bronchodilation and have also been used in combination with beta2-agonists in the management of chronic asthma. ⋯ Overall this review provides no justification for routinely introducing anticholinergics as part of add-on treatment for patients whose asthma is not well controlled on standard therapies. This does not exclude the possibility that there may be a sub-group of patients who derive some benefit and a trial of treatment in individual patients may still be justified. The role of long term anticholinergics such as tiotropium bromide has yet to be established in patients with asthma and any future trials might draw on the messages derived from this review.

ReviewCurative surgery for obstruction from primary left colorectal carcinoma: primary or staged resection?
In 8 to 29% of patients with colorectal carcinoma, obstruction is the main symptom at diagnosis, and 85% of patients undergoing emergency colorectal surgery have obstruction from colorectal carcinoma. The prognosis of patients who undergo emergency surgery for obstruction is often poor. So far, two types of surgical approach have been used for this condition: primary resection (primary anastomosis or Hartmann's procedure) with simultaneous treatment of carcinoma and obstruction, or staged resection (treatment of the obstruction prior to resection).However, neither strategy has been found to have any advantages over the other. ⋯ The limited number of identified trials together with their methodological weaknesses do not allow a reliable assessment of the role of either therapeutic strategy in the treatment of patients with bowel obstruction from colorectal carcinoma. It would appear advisable to conduct high quality large scale RCT to establish which treatment is more effective. However, it is doubtful whether they could be carried out in a timely and satisfactory way in this particular surgical context.

ReviewBladder neck needle suspension for urinary incontinence in women.
Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of them have moderate or severe symptoms. ⋯ Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary and secondary urodynamic stress incontinence because the cure rates were lower in the trials reviewed. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity.
