Melioidosis is an infectious disease caused by a bacterium (Burkholderia pseudomallei) found particularly in some areas in the tropics. It is a serious condition which can be fatal. Beta lactam antibiotics have dramatically reduced the risk of death, but mortality still remains high. ⋯ Regimens for the acute phase of illness should contain ceftazidime or imipenem. It is not yet clear if combinations of treatments in the early phase reduce relapse. For oral therapy after the acute phase of treatment, trials suggest that conventional four drug regimens can be used for treatment.

Jet-lag commonly affects air travellers who cross several time zones. It results from the body's internal rhythms being out of step with the day-night cycle at the destination. Melatonin is a pineal hormone that plays a central part in regulating bodily rhythms and has been used as a drug to re-align them with the outside world. ⋯ Melatonin is remarkably effective in preventing or reducing jet-lag, and occasional short-term use appears to be safe. It should be recommended to adult travellers flying across five or more time zones, particularly in an easterly direction, and especially if they have experienced jet-lag on previous journeys. Travellers crossing 2-4 time zones can also use it if need be. The pharmacology and toxicology of melatonin needs systematic study, and routine pharmaceutical quality control of melatonin products must be established. The effects of melatonin in people with epilepsy, and a possible interaction with warfarin, need investigation.

ReviewAntibiotic prophylaxis for surgery for proximal femoral and other closed long bone fractures.
Wound infection and other hospital-acquired infections cause significant morbidity after internal fixation of fractures (osteosynthesis). The administration of antimicrobial agents (antibiotics) may reduce the frequency of infections. ⋯ Antibiotic prophylaxis should be offered to those undergoing surgery for closed fracture fixation. On ethical grounds, further placebo controlled randomised trials of the effectiveness of antibiotic prophylaxis in closed fracture surgery are unlikely to be justified. Trials addressing the cost-effectiveness of different effective antibiotic regimens would need to be very large.

ReviewWhat is the role of stimulant laxatives in the management of childhood constipation and soiling?.
Constipation is extremely common in childhood and may lead to overflow soiling/encopresis. Standard treatment of the more severe case is to empty the bowels of impacted faeces by the use of oral or rectal laxatives and then maintain regular bowel movements by the continuation of osmotic and stimulant laxatives. ⋯ The need exists to establish a secure footing for treatment decisions and adequately sized trials are required to provide comparative data on commonly used drugs.

This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology. ⋯ Oral prostaglandin consistently resulted in more frequent gastrointestinal side effects, in particular vomiting, compared with the other treatments included in this review. There were no clear advantages to oral prostaglandin over other methods of induction of labour.
