In emergency contraception a drug or IUD is used to prevent pregnancy shortly after unprotected intercourse. Except for some Western-European countries and China, emergency contraception is largely under-utilised worldwide. In many developing countries lack of access to emergency contraception may subject women to unsafe abortions, which contribute significantly to maternal mortality and morbidity. Currently, several interventions (IUD, the Yuzpe regimen, levonorgestrel, mifepristone, danazol and some combination regimens) are available for emergency contraception. Information on the comparative efficacy, safety and convenience of these methods is crucial for reproductive health care providers and the women they serve. ⋯ Levonorgestrel 1.5 mg (two split doses or a single dose) and low and mid-doses (25-50 mg) of mifepristone offer high efficacy with an acceptable side-effect profile. Single dose simplifies the use of levonorgestrel for emergency contraception without an increase in side-effects. However, mifepristone might delay the following menstruation, which could increase anxiety, particularly in higher doses. The Yuzpe regimen could be used if levonorgestrel or mifepristone are not available. The intrauterine device (IUD) is another effective emergency contraceptive, and can be kept for ongoing contraception.

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.

Impetigo is a common superficial bacterial skin infection, most frequently encountered in children. There is no standard therapy and guidelines for treatment differ widely. Treatment options include many different oral and topical antibiotics as well as disinfectants. ⋯ Data on the natural course of impetigo are lacking. Placebo controlled trials are scarce. There is little evidence about the value of disinfecting measures. There is good evidence that topical mupirocin and topical fusidic acid are equally, or more effective than oral treatment for people with limited disease. It is unclear if oral antibiotics are superior to topical antibiotics for people with extensive impetigo. Fusidic acid and mupirocin are of similar efficacy. Penicillin was not as effective as most other antibiotics. Resistance patterns against antibiotics change and should be taken into account in the choice of therapy.

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.

ReviewProphylactic intravenous antifungal agents to prevent mortality and morbidity in very low birth weight infants.
Invasive fungal infection is an increasingly common cause of mortality and morbidity in very low birth weight infants. As the diagnosis is often difficult, and treatment is often delayed, there is a need to assess whether antifungal prophylaxis is beneficial. ⋯ We have found some evidence that prophylactic intravenous fluconazole reduces mortality prior to hospital discharge in very low birth weight infants. The meta-analysis suggests that there will be one fewer death in every nine infants treated with this intervention, but the 95% confidence interval around this estimate of effect is wide. The longer term neurodevelopmental consequences for infants exposed to this intervention remain to be determined. It will be important to identify any subgroups of very low birth weight infants that receive the most benefit from this intervention. There is also a need for further data on the effect of the intervention on the emergence of organisms with stable antifungal resistance.
