ReviewNonsteroidal anti-inflammatory drugs (NSAIDs) versus opioids for acute renal colic.
Renal colic is a common cause of acute severe pain. Both opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended for treatment, but the relative efficacy of these drugs is uncertain. ⋯ Both NSAIDs and opioids can provide effective analgesia in acute renal colic. Opioids are associated with a higher incidence of adverse events, particularly vomiting. Given the high rate of vomiting associated with the use of opioids, particularly pethidine, and the greater likelihood of requiring further analgesia, we recommend that if an opioid is to be used it should not be pethidine.

ReviewOral immunoglobulin for preventing necrotizing enterocolitis in preterm and low birth-weight neonates.
Necrotizing enterocolitis (NEC) is the most common emergency of the gastrointestinal tract occurring in the neonatal period. There have been published reports which suggest that oral immunoglobulins IgA and IgG produce an immunoprotective effect in the gastrointestinal mucosa. This systematic review was undertaken to clarify the issue. ⋯ Based on the available trials, the evidence does not support the administration of oral immunoglobulin for the prevention of NEC. There are no randomised controlled trials of oral IgA alone for the prevention of NEC.

Bronchodilators are commonly used in the management of bronchiolitis. A recent systematic review showed that bronchodilators produce modest short-term benefit among patients with mild or moderate bronchiolitis. ⋯ There is insufficient evidence to support the use of epinephrine for the treatment of bronchiolitis among inpatients. There is some evidence to suggest that epinephrine may be favourable to salbutamol and placebo among outpatients. A number of large, multi-centered trials are required to examine the effectiveness of epinephrine compared to placebo and salbutamol for infants presenting to outpatient settings. There is a need to develop a validated, reliable scoring system that is sensitive to important clinical changes in patients with bronchiolitis.

Review Meta AnalysisDual chamber versus single chamber ventricular pacemakers for sick sinus syndrome and atrioventricular block.
Dual chamber pacing or single chamber atrial pacing ('physiologic' pacing) is believed to have an advantage over single chamber ventricular pacing in that it resembles cardiac physiology more closely by maintaining atrioventricular (AV) synchrony and dominance of the sinus node, which in turn may reduce cardiovascular morbidity and mortality thus contributing to patient survival and quality of life. However, a significant proportion of pacemakers currently implanted are single chamber ventricular pacemakers. ⋯ This review shows a trend towards greater effectiveness with dual chamber pacing compared to single chamber ventricular pacing, which supports the current British Pacing and Electrophysiology Group's Guidelines regarding atrioventricular block. Additional randomised controlled trial evidence from ongoing trials in this area will further inform the debate.

While population based screening for lung cancer has not been adopted by most countries, it is not clear whether sputum examinations, chest radiography or newer methods such as computed tomography are effective in reducing mortality from lung cancer. ⋯ The current evidence does not support screening for lung cancer with chest radiography or sputum cytology. Frequent chest x-ray screening might be harmful. Further, methodologically rigorous trials are required.
