ReviewTranscutaneous electrical nerve stimulation (TENS) for chronic low back pain.
Low back pain (LBP) affects a large proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an alternative therapy to pharmacological treatments for chronic pain. However, despite its widespread use, the effectiveness of TENS is still controversial. ⋯ The results of the meta-analysis present no evidence to support the use of TENS in the treatment of chronic low back pain. Clinicians and researchers should consistently report the characteristics of the TENS device and the application techniques used. New trials on TENS should make use of standardized outcome measures. This meta-analysis lacked data on how TENS effectiveness is affected by four important factors: type of applications, site of application, treatment duration of TENS, optimal frequencies and intensities.

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.

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.

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.

ReviewEfficacy of nicergoline in dementia and other age associated forms of cognitive impairment.
Nicergoline is an ergot derivative currently in use in over fifty countries for more than three decades, for the treatment of cognitive, affective, and behavioral disorders of older people. It was initially considered as a vasoactive drug and mainly prescribed for cerebrovascular disorders. Recent findings suggest other actions which has provided a rationale for the use of nicergoline for the treatment of various forms of dementia, including Alzheimer's Disease. ⋯ The clinical studies on nicergoline were carried out with diverse criteria and modalities of evaluation. Despite this, the 14 studies included in this review, have presented generally consistent results. Results of this meta-analysis provide some evidence of positive effects of nicergoline on cognition and behaviour and these effects are supported by an effect on clinical global impression. There was some evidence that there were increased risk of adverse effects associated with nicergoline. These results were obtained on older patients with mild to moderate cognitive and behavioural impairment of various clinical origins, including chronic cerebrovascular disorders and Alzheimer's dementia. The few studies specifically performed on patients with Alzheimer's disease were performed with too few people to give a definitive answer to the questions concerning the use of nicergoline for this form of dementia. This drug has not been evaluated using current diagnostic categories such as MCI or in association with therapeutic agents of different nature such as cholinesterase or antioxidant drugs.
