ReviewReduced osmolarity oral rehydration solution for treating dehydration caused by acute diarrhoea in children.
Oral rehydration solution (ORS) has reduced childhood deaths from diarrhoea in many countries. Recent studies suggest that the currently recommended formulation of ORS recommended by the World Health Organization (WHO) may not be optimal, and solutions that contain lower concentrations of sodium and glucose may be more effective. ⋯ In children admitted to hospital with diarrhoea, reduced osmolarity ORS when compared to WHO ORS is associated with fewer unscheduled intravenous infusions, smaller stool volume post randomisation, and less vomiting. No additional risk of developing hyponatraemia when compared with WHO ORS was detected.

Review Comparative StudyA comparison of speech and language therapy techniques for dysarthria in Parkinson's disease.
Dysarthria is a common manifestation of Parkinson's disease that increases in frequency and intensity with the progress of the disease (Streifler 1984). Up to 20% of Parkinsonian patients are referred for speech and language therapy (S & LT), its aim being to improve the intelligibility of the patient's speech. ⋯ Considering the methodological flaws in both of these studies, the small number of patients examined, and the possibility of publication bias, there is insufficient evidence to support or refute the efficacy of any given form of S & LT over another to treat dysarthria in Parkinson's disease. Given the lack of evidence from RCTs to support or refute the efficacy of S & LT in Parkinson's disease (see Cochrane review 'Speech and Language therapy for Dysarthria in Patients with Parkinson's Disease'), the consensus as to what is considered 'best-practice' S & LT must be proved first through a large well-designed placebo-controlled randomised trial before examining variations in S & LT methodology. The design of these trials should minimise bias and be reported fully using CONSORT guidelines (CONSORT 1996). Outcome measures with particular relevance to patients, their carers, physicians and speech and language therapists should be chosen and the patients followed for at least 6 months to determine the duration of any improvement.

Aphasia describes language impairment associated with a brain lesion. ⋯ The main conclusion of this review is that drug treatment with piracetam may be effective in the treatment of aphasia after stroke. Further research is needed to explore the effects of drugs for aphasia, in particular piracetam. If a trial is done, this must be large enough to have adequate statistical power. The safety of the drug should be of primary interest. Researchers should examine the long term effects of this treatment, and whether it is more effective than speech and language therapy.

ReviewStapled versus handsewn methods for colorectal anastomosis surgery.
Randomized controlled trials comparing stapled with handsewn colorectal anastomosis have not shown either technique to be superior, perhaps because individual studies lacked statistical power. A systematic review, with pooled analysis of results, might provide a more definitive answer. ⋯ The evidence found was insufficient to demonstrate any superiority of stapled over handsewn techniques in colorectal anastomosis, regardless of the level of anastomosis.

Routine use of caesarean section for breech presentation is widespread. However, poor outcomes after breech birth might be the result of underlying conditions causing breech presentation rather than damage during delivery. ⋯ Planned caesarean section greatly reduces both perinatal/neonatal mortality and neonatal morbidity, at the expense of somewhat increased maternal morbidity. Cost, and future morbidity due to the caesarean section scar were not assessed. The option of external cephalic version is dealt with in separate reviews. The data from this review will help to inform individualised decision-making regarding breech delivery.
