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.

Interest in zinc as a treatment for the common cold has grown following the recent publication of several controlled trials. The objective of this review was to assess the effects of zinc lozenges for cold symptoms. ⋯ Evidence of the effects of zinc lozenges for treating the common cold is inconclusive. Given the potential for treatment to produce side effects, the use of zinc lozenges to treat cold symptoms deserves further study.

Surgical bypass of an occluded arterial segment is the mainstay of treatment for patients with critical limb ischaemia. As with many surgical interventions, however, it was introduced without formal evaluation. ⋯ There is limited evidence for the effectiveness of bypass surgery and further large trials are required.

ReviewProphylactic synthetic surfactant for preventing morbidity and mortality in preterm infants.
This section is under preparation and will be included in the next issue. ⋯ Prophylactic intratracheal administration of synthetic surfactant to infants judged to be at risk of developing respiratory distress syndrome has been demonstrated to improve clinical outcome. Infants who receive prophylactic synthetic surfactant have a decreased risk of pneumothorax, a decreased risk of pulmonary interstitial emphysema, and a decreased risk of neonatal mortality. Infants who receive prophylactic synthetic surfactant have an increased risk of developing patent ductus arteriosus and pulmonary hemorrhage.

ReviewProphylactic natural surfactant extract for preventing morbidity and mortality in preterm infants.
This section is under preparation and will be included in the next issue. ⋯ Prophylactic intratracheal administration of natural surfactant extract to infants judged to be at risk of developing respiratory distress syndrome (intubated infants <30 weeks gestation) has been demonstrated to improve clinical outcome. Infants who receive prophylactic natural surfactant extract have a decreased risk of pneumothorax, a decreased risk of pulmonary interstitial emphysema, a decreased risk of mortality, and a decreased risk of bronchopulmonary dysplasia or death.
