ReviewSurgical versus medical treatment with cyclooxygenase inhibitors for symptomatic patent ductus arteriosus in preterm infants.
Patent ductus arteriosus (PDA) with significant left to right shunt in preterm infants increases morbidity and mortality. Early closure of the ductus arteriosus may be achieved pharmacologically using cyclooxygenase inhibitors or by surgery. The efficacy of both treatment modalities is well established. However, the preferred initial treatment of a symptomatic PDA in a preterm infant, surgical ligation or treatment with indomethacin, has not been well established. ⋯ The data regarding net benefit/harm are insufficient to make a conclusion as to whether surgical ligation or medical treatment with indomethacin is preferred as initial treatment for symptomatic PDA in preterm infants. It should be noted that three recent observational studies indicated an increased risk for one or more of the following outcomes associated with PDA ligation; chronic lung disease, retinopathy of prematurity and neurosensory impairment . It is possible that the duration of the "waiting-time" and transport to another facility with surgical capacity to have the PDA ligated could adversely affect outcomes, as could the perioperative care.

Venous leg ulcers are a type of chronic wound affecting up to 1% of adults in developed countries at some point during their life. Many of these wounds are colonised by bacteria or show signs of clinical infection. The presence of infection may delay ulcer healing. There are two main strategies used to prevent and treat clinical infection in venous leg ulcers: systemic antibiotics and topical antibiotics or antiseptics. ⋯ At present, there is no existing evidence to support the routine use of systemic antibiotics to promote healing in venous leg ulcers. However, the lack of reliable evidence means that it is not possible to recommend the discontinuation of any of the agents reviewed. In terms of topical preparations, there is some evidence to support the use of cadexomer iodine. Further good quality research is required before definitive conclusions can be made about the effectiveness of systemic antibiotics and topical preparations such as povidone iodine, peroxide-based preparations, ethacridine lactate and mupirocin in healing venous leg ulceration. In light of the increasing problem of bacterial resistance to antibiotics, current prescribing guidelines recommend that antibacterial preparations should only be used in cases of defined infection and not for bacterial colonisation.

Review Meta AnalysisRocuronium versus succinylcholine for rapid sequence induction intubation.
Patients requiring emergency endotracheal intubation often require a rapid sequence induction (RSI) intubation technique to protect against aspiration or increased intracranial pressure, or to facilitate intubation. Succinylcholine is the most commonly used muscle relaxant because of its fast onset and short duration; unfortunately, it can have serious side effects. Rocuronium has been suggested as an alternative to succinylcholine for intubation. This meta-analysis is an update since our initial Cochrane systematic review in 2003. ⋯ Succinylcholine created superior intubation conditions to rocuronium when comparing both excellent and clinically acceptable intubating conditions.

Review Meta AnalysisCyclical progestogens for heavy menstrual bleeding.
Excessively heavy menstrual bleeding (HMB) or menorrhagia is an important cause of ill health in women. Eighty per cent of women treated for HMB have no anatomical pathology, which makes medical therapy, with the avoidance of possibly unnecessary surgery, an attractive alternative. Of the wide variety of medications used to reduce heavy menstrual bleeding, oral progestogens are the most commonly prescribed. This review assesses the effectiveness of two different regimens of oral progestogens in reducing ovulatory HMB. ⋯ Progestogens administered from day 15 or 19 to day 26 of the cycle offer no advantage over other medical therapies such as danazol, tranexamic acid, non-steroidal anti-inflammatory drugs (NSAIDs) and the IUS in the treatment of menorrhagia in women with ovulatory cycles. Progestogen therapy for 21 days of the cycle results in a significant reduction in menstrual blood loss, although women found the treatment less acceptable than intrauterine levonorgestrel. This regimen of progestogen may have a role in the short-term treatment of menorrhagia.

Several rehabilitation programs are available for individuals after lumbar disc surgery. ⋯ Exercise programs starting four to six weeks post-surgery seem to lead to a faster decrease in pain and disability than no treatment. High intensity exercise programs seem to lead to a faster decrease in pain and disability than low intensity programs. There were no significant differences between supervised and home exercises for pain relief, disability, or global perceived effect. There is no evidence that active programs increase the re-operation rate after first-time lumbar surgery.
