ReviewAntiplatelet agents for preventing and treating pre-eclampsia.
Pre-eclampsia is associated with deficient intravascular production of prostacyclin, a vasodilator, and excessive production of thromboxane, a platelet-derived vasoconstrictor and stimulant of platelet aggregation. These observations led to the hypotheses that antiplatelet agents, and low dose aspirin in particular, might prevent or delay the development of pre-eclampsia. ⋯ Antiplatelet agents, in this review largely low dose aspirin, have small-moderate benefits when used for prevention of pre-eclampsia. Further information is required to assess which women are most likely to benefit, when treatment should be started, and at what dose.

ReviewNeuraminidase inhibitors for preventing and treating influenza in healthy adults.
Influenza is an acute respiratory infection associated with raised temperature, headache, muscle ache and cough. The objective of this review was to assess the effects of neuraminidase inhibitors (NIs) in preventing cases of influenza and shortening or reducing the severity of influenza in healthy adults. A further objective was to estimate the frequency of adverse effects associated with NI administration. ⋯ NIs are effective for the prevention and treatment of influenza. Overall NIs are safe, although Oseltamivir causes significant nausea.

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.

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.
