Carotid endarterectomy reduces the risk of stroke in people with recently symptomatic, severe carotid artery stenosis. However, there are significant perioperative risks which may be lessened by performing the operation under local rather than general anaesthetic. ⋯ There is not enough evidence from randomised trials comparing carotid endarterectomy performed under local as opposed to general anaesthetic. Non-randomised studies suggest potential benefits with local anaesthetic. However these studies are likely to be significantly biased.

Review Comparative StudyFully intermittent dosing with drugs for tuberculosis.
The number of people infected with tuberculosis continues to rise world-wide. Rifampicin-containing treatment regimens can achieve high cure rates. Intermittent drug treatment delivered in the community has the potential to improve adherence to treatment. ⋯ There is not enough evidence to assess the equivalence of effect between fully intermittent, rifampicin-containing short-course chemotherapy and similar daily therapy in patients with pulmonary tuberculosis. Larger randomised studies are required to establish the effectiveness of fully intermittent, short-course chemotherapy.

Cranberries (particularly in the form of cranberry juice) have been used widely for several decades for the prevention and treatment of urinary tract infections. The aim of this review is to assess the effectiveness of cranberries in treating such infections. ⋯ After a thorough search, no randomised trials which assessed the effectiveness of cranberry juice for the treatment of urinary tract infections were found. Therefore, at the present time, there is no good quality evidence to suggest that it is effective for the treatment of urinary tract infections. Well-designed parallel group, double blind trials comparing cranberry juice and other cranberry products versus placebo to assess the effectiveness of cranberry juice in treating urinary tract infections are needed. Outcomes should include reduction in symptoms, sterilisation of the urine, side effects and adherence to therapy. Dosage (amount and concentration) and duration of therapy should also be assessed. Consumers and clinicians will welcome the evidence from these trials.

Surgery is increasingly performed on a day-case basis. Many patients are anxious pre-operatively and might benefit from pharmacological anxiolysis. Drugs are sometimes not used, however, for fear of delaying discharge from hospital. ⋯ We have found no evidence of a difference in time to discharge from hospital in patients who received anxiolytic premedication. However, in view of the age and variety of anaesthetic techniques used, inferences for current day-case practice should be made with caution.

ReviewVenepuncture versus heel lance for blood sampling in term neonates.
Heel lance has been the conventional method of blood sampling in neonates for screening tests. Neonates undergoing this procedure experience pain. Despite various studies evaluating the role of pharmacological and non-pharmacological interventions to date, there are no effective and practical methods to alleviate pain from heel lance. ⋯ Venepuncture, when performed by a trained phlebotomist, appears to be the method of choice for blood sampling in term neonates. For each two venepunctures instead of heel lance, the need for one additional skin puncture can be avoided. In view of the promising results derived from small studies with some methodological limitations, further well designed randomized controlled trials need to be conducted. The interventions should be compared in settings where several individuals perform the venepuncture and/or the heel lance.
