ReviewSynthetic surfactant for respiratory distress syndrome in preterm infants.
This section is under preparation and will be included in the next issue. ⋯ Six randomized controlled trials of synthetic surfactant treatment of established respiratory distress syndrome were identified. Five of the studies used Exosurf Neonatal (a synthetic surfactant composed of dipalmitoylphosphatidylcholine, hexadecanol and tyloxapol); one small study utilized a mixture of dipalmitoylphosphatidylcholine (DPPC) and phosphatidylglycerol (PG). Treatment with intratracheal Exosurf Neonatal in premature infants with established respiratory distress syndrome improves pulmonary gas exchange and decreases the requirement for ventilatory support. In individual trials, the use of Exosurf Neonatal resulted in a statistically significant reduction in pneumothorax, patent ductus arteriosus, bronchopulmonary dysplasia (BPD), BPD or death at 28 days, and mortality. Similar results are seen when these large trials of Exosurf Neonatal are analyzed in conjunction with the smaller trial of dry powdered DPPC and phosphatidylglycerol (PG). The meta-analysis supports a decrease in the risk of pneumothorax (typical relative risk 0.64, 95% CI 0.55, 0.76, typical risk difference -0.09, 95% CI -0.12,-0.06), a decrease in the risk of pulmonary interstitial emphysema (typical relative risk 0.62, 95% CI 0.54, 0.71, typical risk difference -0.12, 95% CI -0.16, -0.09), a decrease in the risk of patent ductus arteriosus (typical relative risk 0.90, 95% CI 0.84, 0.97; typical risk difference -0.06 95% CI -0.10, -0.02), a decrease in the risk of intraventricular hemorrhage (typical relative risk 0.88, 95% CI 0.77, 0.99; typical risk difference -0.04, 95% CI -0.08, -0.00), a decrease in the risk of bronchopulmonary dysplasia (typical relative risk 0.75, 95% CI 0.61, 0.92; typical risk difference -0.04, 95% CI -0.06, -0.01), a decrease in the risk of neonatal mortality (typical relative risk 0. 73, 95% CI 0.61, 0.88; typical risk difference -0.05, 95% CI -0.07, -0.02), a decrease in the risk of bronchopulmonary dysplasia or death at 28 days (typical relative risk 0.73, 95% CI 0.65, 0.83; typical risk difference -0.06, 95% CI -0.11, -0.05), a decrease in the risk of mortality prior to hospital discharge (typical relative risk 0.79, 95% CI 0.68, 0.92; typical risk difference -0.05, 95% CI -0.07, -0.02) and a decrease in the risk of mortality during the first year of life (typical relative risk 0.80, 95% CI 0.69, 0.94; typical risk difference -0.04, 95% CI -0.07, -0.01).

Inotropes are widely used in preterm infants to treat systemic hypotension. The most commonly used drugs are dopamine and dobutamine. These agents have different modes of action which may result in different haemodynamic effects. ⋯ Dopamine is more effective than dobutamine in the short term treatment of systemic hypotension in preterm infants. There was no evidence of an effect on the incidence of adverse neuroradiological sequelae (severe periventricular haemorrhage and/or periventricular leucomalacia), or on the incidence of tachycardia. However, in the absence of data confirming long term benefit and safety of dopamine compared to dobutamine, no firm recommendations can be made regarding the choice of drug to treat hypotension.

Auranofin is an oral gold compound used for the treatment of rheumatoid arthritis RA. The use of auranofin has declined in the past few years, perhaps due in part to conflicting results from different studies. ⋯ Auranofin appears to have a small clinically and statistically significant benefit on the disease activity of patients with RA. The beneficial effects appear to be modest compared to drugs such as methotrexate or parenteral gold. Its effects on long term health status and radiological progression are not clear at this time.

ReviewProgestagens and anti-progestagens for pain associated with endometriosis.
Endometriosis is a gynaecological condition that presents either with the problem of infertility or with painful symptoms. The clinical observation of an apparent resolution of symptoms during pregnancy gave rise to the concept of treating patients with a pseudo-pregnancy regime. Initially combinations of high dose oestrogens and progestagens were used but this was subsequently replaced by progestogens alone. More recently progestogens of both progestagens and anti-progestagens in the treatment of symptomatiprogestogenssis ⋯ The limited available data suggests that both continuous progestagens and anti-progestagens are effective therapies in the treatment of painful symptoms associated with endometriosis. Progestagens given in the luteal phase are not effective. These conclusions should be accepted cautiously due to a lack of data.

ReviewInhaled short acting beta2-agonist use in asthma: regular vs as needed treatment.
Inhaled beta2-adrenergic agonists delivered by inhalation are very widely used in asthma. There has been much controversy of the use and possible consequences of the use of these agents for regular, as opposed as-needed use in asthma. ⋯ These results support current guidelines. There is little advantage in using short-acting beta2-agonists regularly, and potentially some small clinical disadvantage.
