ReviewInhaled beta2-agonists for treating non-specific chronic cough in children.
The pathophysiology of so called 'cough variant asthma' has not received a great deal of research interest and opinion lies divided as to whether it is really asthma or not. The proponents of cough variant asthma suggest a therapeutic trial of medications usually used to treat asthma ⋯ Salbutamol was no different from placebo in reducing the frequency of cough measured objectively or scored subjectively.

ReviewBreast stimulation for cervical ripening and induction of labour.
Breast stimulation has been suggested as a means of inducing labour. It is a non-medical intervention allowing women greater control over the induction process. This is one of a series of reviews of methods of cervical ripening and labour induction using a standardised methodology. ⋯ Breast stimulation appears beneficial in relation to the number of women not in labour after 72 hours, and reduced postpartum haemorrhage rates. Until safety issues have been fully evaluated it should not be used in high-risk women. Further research is required to evaluate its safety, and should seek data on postpartum haemorrhage rates, number of women not in labour at 72 hours and maternal satisfaction.

ReviewLaparoscopic "drilling" by diathermy or laser for ovulation induction in anovulatory polycystic ovary syndrome.
Problems in inducing ovulation in women with polycystic ovary syndrome (PCOS) and anovulation (failure to ovulate) are well recognised. Surgical ovarian wedge resection was the first established treatment for anovulatory PCOS patients but was largely abandoned due to the risk of post-surgical adhesions and the introduction of medical ovulation induction with clomiphene and gonadotrophins. However patients with PCOS treated with gonadotrophins often have an over-production of follicles and are exposed to the risks of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. Moreover ovulation induction with gonadotrophins, though effective, is an expensive, inconvenient and time-consuming treatment requiring intensive monitoring. Surgical therapy with laparoscopic ovarian "drilling" (LOD) may avoid or reduce the need for gonadotrophins or may facilitate their use. The procedure can be done on an outpatient basis with less trauma and fewer postoperative adhesions. Many uncontrolled observational studies have claimed that ovarian drilling is followed, at least temporarily, by a high rate of spontaneous ovulation and conception, and/or that subsequent medical ovulation induction becomes easier. ⋯ There was no evidence of a difference in the live birth rate and miscarriage rate in women with clomiphene resistant PCOS undergoing LOD compared to gonadotrophin treatment. The reduction in multiple pregnancy rates in women undergoing LOD makes this option attractive. However, there are ongoing concerns about long term effects of LOD on ovarian function.

ReviewCellulose, modified cellulose and synthetic membranes in the haemodialysis of patients with end-stage renal disease.
When the kidney fails the blood-borne metabolites of protein breakdown and water cannot be excreted. The principle of haemodialysis is that such substances can be removed when blood is passed over a semipermeable membrane. Natural membrane materials include cellulose or modified cellulose, more recently various synthetic membranes have been developed. Synthetic membranes are regarded as being more "biocompatible" in that they incite less of an immune response than cellulose-based membranes. ⋯ We found no evidence of benefit when synthetic membranes were compared with cellulose/modified cellulose membranes in terms of reduced mortality no reduction in dialysis-related adverse symptoms. Despite the relatively large number of RCTs undertaken in this area none of the included studies reported any measures of quality of life.

HIV-infected people and AIDS patients often seek complementary therapies including herbal medicines due to reasons such as unsatisfactory effects, high cost, non-availability, or adverse effects of conventional medicines. ⋯ There is insufficient evidence to support the use of herbal medicines in HIV-infected individuals and AIDS patients. Potential beneficial effects need to be confirmed in large, rigorous trials.
