Review Meta AnalysisCombination formoterol and inhaled steroid versus beta2-agonist as relief medication for chronic asthma in adults and children.
Formoterol has a fast onset of action and can therefore be used to relieve symptoms of asthma. A combination inhaler can deliver formoterol with different doses of inhaled corticosteroid; when used as a reliever both drugs will be delivered more frequently when asthma symptoms increase. This has the potential to treat both bronchoconstriction and inflammation in the early stages of exacerbations. ⋯ In mild asthma it is not yet known whether patients who use a budesonide/formoterol inhaler for relief of asthma symptoms derive any clinically important benefits. In more severe asthma, one study that enrolled patients who were not controlled on quite high doses of inhaled corticosteroids, and had suffered an exacerbation in the previous year, demonstrated a reduction in the risk of exacerbations that require oral corticosteroids with budesonide/formoterol for maintenance and relief in comparison with budesonide/formoterol for maintenance and terbutaline or formoterol for relief. The incidence of serious adverse events in children was also less using budesonide/formoterol for maintenance and relief in one study, which similarly enrolled children who were not controlled on medium to high doses of inhaled corticosteroids, and compared to terbutaline relief with an explorative maintenance dose of budesonide/formoterol that is not approved for treatment.

Review Meta AnalysisHormone replacement therapy to maintain cognitive function in women with dementia.
As estrogens have been shown to have several potentially beneficial effects on the central nervous system, it is biologically plausible that maintaining high levels of estrogens in postmenopausal women by means of estrogen replacement therapy (ERT) could be protective against cognitive decline in women with Alzheimer's disease (AD) or other dementia syndromes. ⋯ Currently, HRT or ERT for cognitive improvement or maintenance is not indicated for women with AD.

Review Meta AnalysisMagnesium sulphate for women at risk of preterm birth for neuroprotection of the fetus.
Epidemiological and basic science evidence suggests that magnesium sulphate before birth may be neuroprotective for the fetus. ⋯ The neuroprotective role for antenatal magnesium sulphate therapy given to women at risk of preterm birth for the preterm fetus is now established. The number of women needed to be treated to benefit one baby by avoiding cerebral palsy is 63 (95% confidence interval 43 to 87). Given the beneficial effects of magnesium sulphate on substantial gross motor function in early childhood, outcomes later in childhood should be evaluated to determine the presence or absence of later potentially important neurological effects, particularly on motor or cognitive function.

Review Meta AnalysisMultiple versus single doses of exogenous surfactant for the prevention or treatment of neonatal respiratory distress syndrome.
Randomized controlled trials have demonstrated the efficacy of surfactant therapy in the treatment of infants at risk for or having respiratory distress syndrome (RDS). Due to surfactant inactivation, multiple doses of surfactant may lead to improved outcome. ⋯ In infants with established respiratory distress, a policy of multiple doses of animal derived surfactant extract resulted in greater improvements regarding oxygenation and ventilatory requirements, a decreased risk of pneumothorax and a trend toward improved survival.In infants at high risk of respiratory distress, a policy of multiple doses of synthetic surfactant resulted in greater improvements regarding oxygenation and ventilatory requirements, a decreased risk of NEC and decreased mortality.The ability to give multiple doses of surfactant to infants with ongoing respiratory insufficiency leads to improved clinical outcome and appears to be the most effective treatment policy.

Review Meta AnalysisIntravenous immunoglobulin for chronic inflammatory demyelinating polyradiculoneuropathy.
Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) causes progressive or relapsing weakness and numbness of the limbs, developing over at least two months. Uncontrolled studies suggest that intravenous immunoglobulin (IVIg) helps. ⋯ The evidence from randomised controlled trials shows that intravenous immunoglobulin improves disability for at least two to six weeks compared with placebo, with a number needed to treat of 3.00. During this period it has similar efficacy to plasma exchange and oral prednisolone. In one large trial, benefit of IVIg persisted for 24 and possibly 48 weeks.
