ReviewSuperoxide dismutase for preventing chronic lung disease in mechanically ventilated preterm infants.
Free oxygen radicals have been implicated in the pathogenesis of chronic lung disease in preterm infants. Superoxide dismutase is a naturally occurring enzyme which provides a defence against such oxidant injury. Exogenously administered superoxide dismutase has been tested in clinical trials to prevent chronic lung disease in preterm infants. ⋯ Based on currently available published trials, there is insufficient evidence to draw firm conclusions about the efficacy of superoxide dismutase in preventing chronic lung disease of prematurity. Data from a small number of treated infants suggest that it is well tolerated and has no serious adverse effects.

ReviewOver-the-counter medications for acute cough in children and adults in ambulatory settings.
Acute cough due to upper respiratory tract infection (URTI) is a common symptom. Many health practitioners recommend non-prescription over-the-counter (OTC) medicines as a first-line treatment for cough, but there is little evidence as to whether these drugs are effective. ⋯ There is no good evidence for or against the effectiveness of OTC medicines in acute cough. The results of this review have to be interpreted with caution due to differences in study designs, populations, interventions and outcomes between studies. The numbers of studies in each group were small, and studies often showed conflicting results. Effect sizes in many studies were unclear and it is questionable as to whether all of the positive results are clinically relevant.

ReviewIntravenous immunoglobulin for suspected or subsequently proven infection in neonates.
Congenital and nosocomial infections are important causes of neonatal morbidity and mortality. Maternal transport of immunoglobulins to the fetus mainly occurs after 32 weeks gestation and endogenous synthesis does not begin until several months after birth. Administration of intravenous immunoglobulin provides IgG that can bind to cell surface receptors, provide opsonic activity, activate complement, promote antibody dependent cytotoxicity, and improve neutrophilic chemo luminescence. Theoretically infectious morbidity and morbidity could be reduced by the administration of intravenous immunoglobulin. ⋯ There is insufficient evidence to support the routine administration of IVIG preparations investigated to date to prevent mortality in infants with suspected or subsequently proved neonatal infection. Researchers should be encouraged to undertake well-designed trials to confirm or refute the effectiveness of IVIG to reduce adverse outcomes in neonates with suspected infection.

ReviewShort-term treatment with proton pump inhibitors, H2-receptor antagonists and prokinetics for gastro-oesophageal reflux disease-like symptoms and endoscopy negative reflux disease.
Heartburn affects 25% of the adult population on a monthly basis and represents the core symptom of gastro-oesophageal reflux disease (GORD). Treatment is readily available and puts a large demand on healthcare budgets. Research in the past has focused largely on the treatment of oesophagitis. A majority of GORD patients show no endoscopic abnormalities and in daily practice most patients are treated empirically. ⋯ The findings in this review suggest that antisecretory drugs are effective in the empirical treatment of complaints likely to originate from GORD and in treatment of ENRD and furthermore that PPIs are superior to H2RAs in empirical treatment of typical GORD symptoms, but not in treatment of ENRD.

ReviewActive chest compression-decompression for cardiopulmonary resuscitation.
Active compression-decompression cardiopulmonary resuscitation (ACD CPR) uses a hand-held suction device, applied mid sternum, to compress the chest then actively decompress the chest after each compression. Randomised controlled trials on use of active compression decompression cardiopulmonary resuscitation have results which are discordant. ⋯ Active chest compression-decompression in patients with cardiac arrest is not associated with clear benefit.
