Surgical abortion up to 63 days by vacuum aspiration or dilatation and curettage has been the method of choice since the 1960s. Medical abortion became an alternative method of first trimester pregnancy termination with the availability of prostaglandins in the early 1970s and anti-progesterones in the 1980s. The most widely researched drugs are prostaglandins (PGs) alone, mifepristone alone, methotrexate alone, mifepristone with prostaglandins and methotrexate with prostaglandins. ⋯ Safe and effective medical abortion methods are available. Combined regimens are more effective than single agents. In the combined regimen, the dose of mifepristone can be lowered to 200 mg without significantly decreasing the method effectiveness. Misoprostol vaginally is more effective than orally. Some of the results are based on small studies only and therefore carry some uncertainty. Almost all trials were conducted in hospital settings with good access to support and emergency services. It is therefore not clear if the results are readily applicable to under-resourced settings where such services are lacking even if the agents used are available.

Many people with schizophrenia do not achieve a satisfactory treatment response with ordinary antipsychotic drug treatment. In these cases, various add-on medications are used, among them valproate. ⋯ Based on randomised trial-derived evidence which is currently available, there are no data to support or to refute the use of valproate as a sole agent for schizophrenia. There is some evidence for a more rapid improvement with valproate augmentation, but this effect vanished over time. Given this limited evidence, further large, simple well-designed and reported trials are necessary. These might focus on people with schizophrenia and violent episodes, on those with treatment resistant forms of the disorder and on people with schizoaffective disorders.

ReviewDesmopressin for minimising perioperative allogeneic blood transfusion.
Public concerns regarding the safety of transfused blood have prompted re-consideration of the use of allogeneic (from an unrelated donor) red blood cell (RBC) transfusion, and of a range of techniques designed to minimise transfusion requirements. ⋯ There is no convincing evidence that desmopressin minimises perioperative allogeneic RBC transfusion in patients who do not have congenital bleeding disorders. These data suggest that there is no benefit from using DDAVP as a means of minimising perioperative allogeneic RBC transfusion.

Dysmenorrhoea refers to the occurrence of painful menstrual cramps of uterine origin and is a common gynaecological condition. One possible treatment is spinal manipulation therapy. One hypothesis is that mechanical dysfunction in certain vertebrae causes decreased spinal mobility. This could affect the sympathetic nerve supply to the blood vessels supplying the pelvic viscera, leading to dysmenorrhoea as a result of vasoconstriction. Manipulation of these vertebrae increases spinal mobility and may improve pelvic blood supply. Another hypothesis is that dysmenorrhoea is referred pain arising from musculoskeletal structures that share the same pelvic nerve pathways. The character of pain from musculoskeletal dysfunction can be very similar to gynaecological pain and can present as cyclic pain as it can also be altered by hormonal influences associated with menstruation. ⋯ Overall there is no evidence to suggest that spinal manipulation is effective in the treatment of primary and secondary dysmenorrhoea. There is no greater risk of adverse effects with spinal manipulation than there is with sham manipulation.

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.
