ReviewExtracorporeal membrane oxygenation for severe respiratory failure in newborn infants.
Extracorporeal membrane oxygenation (ECMO) is a complex procedure of life support in severe but potentially reversible respiratory failure, used particularly in mature newborn infants. Although the number of babies requiring ECMO is small, and the ECMO policy invasive and potentially expensive, its benefits may be high. ⋯ A policy of using ECMO in mature infants with severe but potentially reversible respiratory failure would result in significantly improved survival without increased risk of severe disability amongst survivors. For babies with diaphragmatic hernia ECMO offers short term benefits but the overall effect of employing ECMO in this group is not clear. Further studies are needed to refine ECMO techniques; to consider the optimal timing for introducing ECMO; to identify which infants are most likely to benefit; and to address the longer term implications of neonatal ECMO during later childhood and adult life.

ReviewBlood transfusion for preventing stroke in people with sickle cell disease.
Sickle cell disease is a common inherited haemoglobin disorder. The abnormal haemoglobin causes distortion of red blood cells, anaemia, vaso-occlusion and dysfunction in virtually any organ system in the body. Stroke occurs in around 10% of children with sickle cell anaemia, and recurrences after a first stroke are likely. Chronic blood transfusion regimes are often used in an attempt to dilute the sickled red blood cells, thus reducing the risk of vaso-occlusion and stroke. However, the side-effects of such regimens can be severe. ⋯ While the included study demonstrated a significantly reduced risk of stroke in patients receiving regular blood transfusions, the degree of risk must be balanced against the burden of a chronic transfusion regime. Further research is required to establish the use of transfusion in preventing secondary stroke, the age, or length of time after an event, at which transfusion can safely be stopped, and to further define risk factors for stroke in order to reduce the chance of unnecessarily putting children onto a chronic transfusion regime.

ReviewRiluzole for amyotrophic lateral sclerosis (ALS)/motor neuron disease (MND).
Riluzole has been approved for treatment of patients with amyotrophic lateral sclerosis in many countries but not all. Questions persist about its clinical utility because of high cost, modest efficacy and concern over adverse effects. ⋯ Riluzole 100 mg daily is reasonably safe and probably prolongs survival by about two months in patients with amyotrophic lateral sclerosis. More studies are needed, especially to clarify its effect in older patients (over 75 years), and those with more advanced disease.

Trials on the effect of systemic chemotherapy on survival and recurrence in adults with high-grade glioma have had inconclusive results. We undertook a systematic review and meta-analysis to assess the effects of such treatment on survival and recurrence. ⋯ This small but clear improvement in survival from chemotherapy encourages further study of drug treatment of these tumours

ReviewSurgical versus conservative treatment for acute injuries of the lateral ligament complex of the ankle in adults.
Inversion injuries, primarily sprains, of the ankle are one of the most commonly treated injuries. The three main treatment modalities for acute lateral ankle ligament injuries are immobilisation with plaster cast or splint, 'functional treatment' comprising early mobilisation and the use of an external support (e.g. ankle brace or taping), and surgical repair or reconstruction. ⋯ There is insufficient evidence available from randomised controlled trials to determine the relative effectiveness of surgical and conservative treatment for acute injuries of the lateral ligament complex of the ankle. Sufficiently powered, good quality and adequately reported randomised trials of primary surgical repair versus the best available conservative treatment for well-defined injuries are required.
