ReviewMinimal enteral nutrition for promoting feeding tolerance and preventing morbidity in parenterally fed infants.
Because of concern that feedings may increase the risk of necrotizing enterocolitis, some high-risk infants have received prolonged periods of parenteral nutrition without enteral feedings. Providing minimal enteral feedings during this period of parenteral nutrition was developed as a strategy to enhance feeding tolerance and decrease time to reach full feedings. ⋯ The evidence of benefit from MEN in these analyses is not convincing for a variety of reasons--the inherent difficulty of assessing enteral feedings in high-risk infants, the small size and methodologic limitations of the studies to date, unexplained heterogeneity with respect to some of the apparent benefits, the potential for bias to affect the findings in unblinded studies, and the unexcluded possibility that MEN might increase necrotizing enterocolitis. For these reasons, it is unclear whether MEN should be used in lieu of an equal period of time without enteral feedings.

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequently prescribed medications worldwide and are widely used for patients with low back pain. ⋯ In conclusion, the evidence from the 51 trials included in this review suggests that NSAIDs are effective for short-term symptomatic relief in patients with acute low back pain. Furthermore, there does not seem to be a specific type of NSAID which is clearly more effective than others. Sufficient evidence on chronic low back pain is still lacking.

Epilepsy is a common neurological disorder, affecting almost 0.5 to 1% of the population. Nearly 30% of patients with epilepsy are refractory to currently available drugs. Lamotrigine is one of the newer antiepileptic drugs and is the topic of this review. ⋯ Lamotrigine add-on therapy is effective in reducing the seizure frequency, in patients with drug-resistant partial epilepsy. Further trials are needed to assess the long term effects of lamotrigine, and to compare it with other add-on drugs.

Misoprostol is a synthetic prostaglandin which has been used to induce labour. Oral use of the drug misoprostol may be convenient, but an overdose could cause uterine hyperstimulation and precipitate labour which may be life-threatening for both mother and fetus. ⋯ Oral misoprostol may be an effective method for labour induction. However, the data on safety are lacking. It is possible that clinically effective oral regimens may have an unacceptably high incidence of complications such as uterine hyperstimulation and possibly uterine rupture.

ReviewLow-molecular-weight heparins or heparinoids versus standard unfractionated heparin for acute ischaemic stroke.
Low molecular weight heparins and heparinoids may be associated with lower risks of haemorrhage and more powerful antithrombotic effects than standard unfractionated heparin. ⋯ Low molecular weight heparin or heparinoid appear to decrease the occurrence of deep vein thrombosis compared to standard unfractionated heparin, but there are too few data to provide reliable information on their effect on other important outcomes, including death and intracranial haemorrhage.
