Review Comparative StudyNedocromil sodium vs. sodium cromoglycate for preventing exercise-induced bronchoconstriction in asthmatics.
Nedocromil sodium and sodium cromoglycate inhaled shortly before exercise appear to reduce the severity of exercise-induced bronchoconstriction. There is some debate over which drug may be more effective. ⋯ No significant differences were evident between the effect of NCS and SCG during the immediate post-exercise period in adults and children with EIB with regards to pulmonary function - specifically maximum percent decrease in FEV1, complete protection, clinical protection, or side effects.

ReviewNonsteroidal anti-inflammatory drugs for heavy menstrual bleeding.
Heavy menstrual bleeding is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Nonsteroidal anti-inflammatory drugs or prostaglandin synthetase inhibitors reduce prostaglandin levels which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea. ⋯ NSAIDs reduce heavy menstrual bleeding when compared with placebo but are less effective than either tranexamic acid or danazol. However, adverse events are more severe with danazol therapy. In the limited number of small scale studies suitable for evaluation, no significant difference in efficacy was demonstrated between NSAIDs and other medical treatments such as oral progestogen given in the luteal phase, ethamsylate, oral contraceptive pill and the progesterone releasing IUS.

Artemisinin derivatives are a relatively new group of drugs with antimalarial properties. As resistance to other antimalarial drugs continues to increase, artemisinin drugs may be useful alternatives. ⋯ The evidence suggests that artemisinin drugs are effective and safe for treating uncomplicated malaria. There is no evidence from randomised trials that one artemisinin derivative is better than the others. In areas where there is mefloquine resistance, combination therapy with an artemisinin derivative appears to improve sustained parasite clearance compared with either drug alone.

To assess the efficacy of fluoride therapy on bone loss, vertebral and non-vertebral fractures and side effects in postmenopausal women. ⋯ Although fluoride has an ability to increase BMD at lumbar spine, it does not result in a reduction of vertebral fractures. In increasing the dose of fluoride, one increases the risk of non-vertebral fracture and gastrointestinal side effects without any effect on the vertebral fracture rate.

Sickle cell disease is an inherited disorder that occurs throughout the world with its highest incidence in areas of Africa where malaria is endemic. It affects up to one in 60 infants born in some areas of Africa. There are a number of potentially serious complications associated with the condition, and it is suggested that early treatment (before symptoms develop) can improve both morbidity and mortality. Screening for the condition in the neonatal period would enable early diagnosis and therefore early treatment. ⋯ There is a lack of evidence from trials of neonatal screening for sickle cell disease. There is evidence of benefit from early treatment which is made possible by screening and there are a number of reviews and economic analyses of non-trial literature suggesting that screening is appropriate. Health care providers must therefore assess whether the information provided by these documents is relevant to their practice and situation when making decisions regarding neonatal screening for sickle cell disease. Systematic reviews of early treatments/interventions, including penicillin prophylaxis, pneumococcal vaccine and parental education should be considered.
