ReviewNon-invasive physical treatments for chronic/recurrent headache.
Non-invasive physical treatments are often used to treat common types of chronic/recurrent headache. ⋯ A few non-invasive physical treatments may be effective as prophylactic treatments for chronic/recurrent headaches. Based on trial results, these treatments appear to be associated with little risk of serious adverse effects. The clinical effectiveness and cost-effectiveness of non-invasive physical treatments require further research using scientifically rigorous methods. The heterogeneity of the studies included in this review means that the results of a few additional high-quality trials in the future could easily change the conclusions of our review.

ReviewMinilaparotomy and endoscopic techniques for tubal sterilisation.
Worldwide, the most commonly used method of fertility regulation is tubal sterilisation. In developed countries sterilisation is generally performed by laparoscopy rather than by minilaparotomy, based on the belief that this approach is both safe and effective. In developing countries, where the resources are limited for the purchase and maintenance of the more sophisticated laparoscopic equipment, minilaparotomy may still be the most common approach. In both resource poor and industrialised countries using the technique with the greatest effectiveness and safety, together with the least costs, is extremely important. Though both methods are widely used, the advantages and disadvantages of laparoscopic sterilisation compared to mini-laparotomy have not been systematically evaluated. The ideal method would be one which is highly effective, economical, able to be performed on an outpatient basis, allowing rapid resumption of normal activity, producing a minimal or invisible scar and having a potential for reversibility. This review considers the methods to enter the abdominal cavity through the abdominal wall, either by minilaparotomy, laparoscopy or culdoscopy regardless of the technique used for tubal sterilisation. ⋯ Major morbidity seems to be a rare outcome for both, laparoscopy and minilaparotomy. The included studies had limited power to demonstrate significant differences especially for the relatively rare but potentially serious outcomes. Personal preference of the woman and/or of the surgeon can guide the choice of technique. Practical aspects (e.g. cost, maintenance, and sterilisation of the instruments) must be taken into account before implementing the more sophisticated endoscopic techniques in settings with limited resources. Culdoscopy is not recommended as it carries a higher complication rate.

ReviewHormonally impregnated intrauterine systems (IUSs) versus other forms of reversible contraceptives as effective methods of preventing pregnancy.
In the 1970s a new approach to the delivery of hormonal contraception was researched and developed. It was suggested that the addition of a progestogen to a non-medicated contraceptive device improved its contraceptive action. An advantage of these hormonally impregnated intrauterine systems (IUS) is that they are relatively maintenance free, with users having to consciously discontinue using them to become pregnant rather than taking a proactive daily decision to avoid conception. ⋯ Current evidence suggests LNG-20 IUS users are no more or less likely to have unwanted pregnancies than IUD >250mm2 and Norplant-2 users. The LNG-20 IUS was more effective in preventing either intrauterine or extrauterine pregnancies than IUDs <=250mm2. The contraceptive effectiveness of Progestasert was significantly better than non-medicated IUDs, but no difference was observed when compared to IUDs<=250mm2. Continuation of LNG-20 IUS use was similar to continuation of the non-hormonal IUDs and Norplant-2. Amenorrhoea was the main reason for the discontinuation for the LNG-20 IUS and women should be informed of this prior to starting this method.

ReviewNon-pharmaceutical measures for prevention of post-thrombotic syndrome.
Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) characterised by chronic pain, swelling and skin changes in the affected limb. One in every three patients with DVT will develop post-thrombotic complications within five years. ⋯ There is substantial evidence that elastic compression stockings reduce the occurrence of PTS after DVT. No serious adverse effects were mentioned in the studies. Hence, elastic compression stockings should be added to the treatment of DVT to prevent the development of post-thrombotic syndrome.

ReviewBotulinum toxin A as an adjunct to treatment in the management of the upper limb in children with spastic cerebral palsy.
Cerebral palsy (CP) is a central nervous system deficit resulting from a non-progressive lesion in the developing brain. Although the brain lesions are static, the movement disorders that arise are not unchanging and are characterised by atypical muscle tone, posture and movement (Rang 1990). The spastic motor type is the most common form of CP and its conventional therapeutic management may include splinting/casting, passive stretching, facilitation of posture and movement, spasticity-reducing medication and surgery. More recently, health care professionals have begun to use botulinum toxin A (BtA) as an adjunct to interventions in an attempt to reduce muscle tone and spasticity to improve function ⋯ This systematic review has not found sufficient evidence to support or refute the use of intramuscular injections of BtA as an adjunct to managing the upper limb in children with spastic cerebral palsy. Only one of the two identified RCTs reported some promising results in support of reduced muscle tone following BtA injections. Further research incorporating larger sample sizes, rigorous methodology, measurement of upper limb function and functional outcomes is essential.
