The treatment of chronic low back pain is not primarily focused on removing an underlying organic pathology, but at the reduction of disability through the modification of environmental contingencies and cognitive processes. Behavioural interventions are commonly used in the treatment of chronic (disabling) low back pain. ⋯ Behavioural treatment seems to be an effective treatment for chronic low back pain patients, but it is still unknown what type of patients benefit most from what type of behavioural treatment.

ReviewGeneral versus spinal/epidural anaesthesia for surgery for hip fractures in adults.
The majority of hip fracture patients are treated surgically, requiring anaesthesia. ⋯ Regional anaesthesia and general anaesthesia appear to produce comparable results for most of the outcomes studied. Regional anaesthesia may reduce short-term mortality but no conclusions can be drawn for longer term mortality.

Review Meta AnalysisLong-acting beta2-agonists for chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) is characterised by airflow limitation which is only partially reversible. Long acting beta2-agonists, effective in the management of asthma,are also recommended for COPD management so it is important to establish whether these drugs are effective in reducing COPD symptoms in view of the potential side effect and cost burden. ⋯ Treatment of patients with COPD with long acting beta2-agonists produces only small increases in FEV1. In one study, a dose of salmeterol 50 mcg twice daily produced a reduction in breathlessness and a clinically significant improvement in quality of life. (ABSTRACT TRUNCATED)

Pre-eclampsia is a relatively common complication of pregnancy. Anticonvulsants are used in the belief they help prevent eclamptic fits and subsequent poor outcomes for mother and infant. ⋯ There is not enough evidence to establish the benefits and hazards of anticonvulsants for women with pre-eclampsia. If an anticonvulsant is used, magnesium sulphate appears to be the best choice.

ReviewProgesterone/progestogen releasing intrauterine systems versus either placebo or any other medication for heavy menstrual bleeding.
Heavy menstrual bleeding (HMB) is an important cause of ill health in women and it accounts for 12% of all gynaecology referrals in the UK. Heavy menstrual bleeding is clinically defined as greater than, or equal to, 80mls blood loss per menstrual cycle but women may complain of excessive bleeding when their blood loss is less than 80ml. Hysterectomy is often used to treat women with this complaint but medical therapy may be a successful alternative. The intrauterine coil device was originally developed as a contraceptive but the addition of uterine relaxing hormones, or progestogens, to these devices resulted in a large reduction in menstrual blood loss. Case studies of 2 types of progesterone/progestogen releasing systems, Progestasert and Mirena, report reductions of up to 90% and dysmenorrhoea may be improved. Insertion, however, may be regarded as invasive by some women affecting its acceptability as a treatment and frequent intermenstrual bleeding and spotting is likely during the first few months. ⋯ Progesterone/progestogen-releasing intrauterine systems have not been compared to placebo or no treatment. Progestasert has been compared to a number of different medical therapies in one small study but no conclusions can be made about effectiveness. The levonorgestrel-releasing intrauterine device (LNG IUS) has been compared to oral cyclical norethisterone (NET) administered on days 5-26 in one trial and was significantly more effective although there was a large reduction from baseline in both groups and these differences were not perceived by the women undergoing the treatment. Some side effects were more common in the LNG IUS group but a significantly greater proportion of women in this group were satisfied and willing to continue with their treatment. In one trial of women awaiting hysterectomy where the LNG IUS was compared with a control group taking their existing medical therapy, a higher proportion of the women in the former group cancelled their planned surgery after 6 months of treatment. The levonorgestrel-releasing intrauterine device has been compared to a surgical procedure (transcervical resection of the endometrium (TCRE)) in two trials. (ABSTRACT TRUNCATED)
