ReviewSurgical versus conservative interventions for anterior cruciate ligament ruptures in adults.
Anterior cruciate ligament rupture is a common knee injury. Surgical treatment, usually involving reconstruction of the ligament, is widely used especially in active individuals. ⋯ There is insufficient evidence from randomised trials to determine whether surgery or conservative management was best for ACL injury in the 1980s, and no evidence to inform current practice. Good quality randomised trials are required to remedy this situation.

ReviewEthosuximide, sodium valproate or lamotrigine for absence seizures in children and adolescents.
Absence seizures are brief epileptic seizures which present in childhood and adolescence. They are characterised by sudden loss of awareness and an electroencephalogram (EEG) typically shows generalised spike wave discharges at three cycles per second. Ethosuximide, valproate and lamotrigine are currently used to treat absence seizures. This review aims to determine the best choice of anticonvulsant for a child with typical absence seizures. ⋯ Although ethosuximide, lamotrigine and valproate are commonly used to treat people with absence seizures we have insufficient evidence to inform clinical practice, and the few trials included in this review were of poor methodological quality and did not have sufficient number of participants. More trials of better quality are needed.

ReviewHeparin for prolonging peripheral intravenous catheter use in neonates.
Peripheral intravenous (PIV) catheters are widely used in modern medical practice. However, mechanical or infectious complications often necessitate their removal and/or replacement. Heparin has been shown to be effective in prolonging the patency of peripheral arterial catheters and central venous catheters, but may result in life threatening complications, especially in preterm neonates. ⋯ There are insufficient data concerning the effect of heparin for prolonging PIV catheter use in neonates. Further research on the effectiveness, the optimal dose, and the safety of heparin is required.

ReviewNon-invasive positive pressure ventilation for treatment of respiratory failure due to severe acute exacerbations of asthma.
Non-invasive positive pressure ventilation (NPPV) has been shown to be effective in chronic obstructive pulmonary disease (COPD) patients with acute respiratory failure. However, its role in patients with severe acute asthma is uncertain. The pathophysiologic condition of acute respiratory failure in asthma is in many ways similar to that of acute respiratory failure in COPD. Therefore, there is reason to believe that NPPV could also be successful in patients with severe acute asthma. ⋯ The application of NPPV in patients suffering from status asthmaticus, despite some interesting and very promising preliminary results, still remains controversial. Large, prospective randomised controlled trials are therefore needed to determine the role of NPPV in status asthmaticus.

Lung disease in cystic fibrosis is characterised by impaired mucociliary clearance. Hypertonic saline has been shown to enhance mucociliary clearance in vitro and this may act to lessen the destructive inflammatory process in the airways. ⋯ Nebulised hypertonic saline improves mucociliary clearance in short-term clinical trials and appears to increase lung function compared to control. In comparison to recombinant deoxyribonuclease it may be less effective at improving lung function after three months. Currently there is insufficient evidence to support the use of hypertonic saline as routine treatment for people with cystic fibrosis.
