ReviewCombined spinal-epidural versus epidural analgesia in labour.
Traditional epidural techniques have been associated with prolonged labour, use of oxytocin augmentation, and increased incidence of instrumental vaginal delivery. The combined spinal-epidural (CSE) technique has been introduced in an attempt to reduce these adverse effects. CSE is believed to improve maternal mobility during labour and provide more rapid onset of analgesia than epidural analgesia. ⋯ There is no standard CSE or epidural technique. Compared with epidural, CSE provides faster onset of effective pain relief from the time of injection, and increases the incidence of maternal satisfaction. However, CSE women experience more itch. There is no difference between CSE and epidural techniques with respect to: the incidence of forceps delivery, maternal mobility, PDPH, caesarean section rates or admission of babies to the neonatal unit. It is not possible to draw any meaningful conclusions regarding rare complications such as nerve injury and meningitis.

Review Meta AnalysisSpeech and language therapy interventions for children with primary speech and language delay or disorder.
It is thought that approximately 6% of children have speech and language difficulties of which the majority will not have any other significant developmental difficulties. Whilst most children's difficulties resolve, children whose difficulties persist into primary school may have long-term problems concerning literacy, socialisation, behaviour and school attainment. ⋯ The review shows that overall there is a positive effect of speech and language therapy interventions for children with expressive phonological and expressive vocabulary difficulties. The evidence for expressive syntax difficulties is more mixed, and there is a need for further research to investigate intervention for receptive language difficulties. There is a large degree of heterogeneity in the results, and the sources of this need to be investigated.

ReviewNew generation antipsychotics for first episode schizophrenia.
The new generation antipsychotics are associated with a lower risk of adverse effects compared with drugs such as haloperidol. Many treatment guidelines recommend the use of new generation ('atypical') antipsychotic drugs for people with a first episode of schizophrenia. ⋯ The results of this review are inconclusive. Whether the use of new generation antipsychotics really makes the treatment less off putting and enhances long-term compliance is unclear. Pragmatic, well-designed and reported long-term trials would be useful to answer this question.

Rheumatoid arthritis (RA) is a chronic inflammatory joint disease. Leflunomide, as an inhibitor of pyrimidine synthesis, has a different mechanism of action than other existing disease modifying anti-rheumatic drugs (DMARD). ⋯ Leflunomide appears to improve all clinical outcomes and delay radiologic progression at both 6 and 12 months of treatment compared to placebo. Its efficacy and adverse events at 2 years of treatment are comparable to SSZ and MTX. Long-term efficacy and toxicity remains to be established.

Morphine has been used to relieve pain for many years. Oral morphine in either immediate release or sustained release form remains the analgesic of choice for moderate or severe cancer pain. ⋯ The randomised trial literature for morphine is small given the importance of this medicine. Most trials recruited fewer than 100 participants, and did not provide appropriate data for meta-analysis. Trial design was frequently based on titration of morphine or comparator to achieve adequate analgesia, then crossing subjects over in crossover design studies. It is not clear if these trials are sufficiently powered to detect any clinical differences between formulations or comparator drugs.
