ReviewContinuous infusion versus intermittent flushing to prevent loss of function of peripheral intravenous catheters used for drug administration in newborn infants.
The use of peripheral intravenous cannulae is common in newborn babies. Many of them require an intravenous line only for medications and not for fluid. Currently there is little uniformity in methods used to maintain cannula patency. ⋯ It is difficult to draw reliable conclusions given the way the data were analysed and reported in the two included studies. The reliability of the results is uncertain. However, given the caution in interpreting these data, it should also be noted that the use of intermittent flushes was not associated in either study with a decreased cannula life or any other disadvantages, thus lending some support for the use of intermittent flushing of cannulas in a selected population in neonatal nurseries.

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.

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.

People who are prescribed self-administered medications typically take less than half the prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications, but also might increase their adverse effects. ⋯ Improving short-term adherence is relatively successful with a variety of simple interventions. Current methods of improving adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. High priority should be given to fundamental and applied research concerning innovations to assist patients to follow medication prescriptions for long-term medical disorders.

ReviewContinuous heparin infusion to prevent thrombosis and catheter occlusion in neonates with peripherally placed percutaneous central venous catheters.
Peripherally placed percutaneous central venous catheters (PCVC) are used in neonates to provide long-term vascular access. Major complications associated with these catheters include mechanical complications (catheter thrombosis, occlusion or dislodgement) and infection. Strategies to prevent catheter thrombosis and occlusion include the use of heparin. Systematic review has revealed that heparin is effective in prolonging the umbilical arterial catheter stay in neonates. However, heparin is known to be associated with complications such as bleeding and thrombocytopenia which may result in serious long-term sequelae. ⋯ Prophylactic use of heparin for prevention of complications related to peripherally placed PCVC has been examined in only one randomized controlled clinical trial that was eligible for inclusion in this review. No significant differences in the incidence of thrombosis, occlusion, sepsis, mortality and duration of catheter patency were observed. With the current state of knowledge, routine use of heparin for this purpose can not be recommended. Implication for research: Increasing survival of extremely low birth weight infants may be accompanied by prolonged intravenous access for nutrition. Well designed randomized controlled trials of sufficient power to determine the benefits and risks of continuous infusion of heparin in neonates with peripherally inserted PCVC are warranted.
