Patellofemoral pain syndrome is a frequently reported condition in active adults. A wide variety of conservative treatment strategies have been described. As yet, no optimal strategy has been identified. Application of orthotic devices e.g. knee braces, knee straps, forms of taping of the knee, active training devices, knee sleeves and in-shoe orthotics to support the foot have been advocated to treat this condition. ⋯ The evidence from randomised controlled trials is currently too limited to draw definitive conclusions about the use of knee and foot orthotics for the treatment of patellofemoral pain. Future high quality trials in this field are warranted.

Paracetamol (acetaminophen) is widely used for treating fever in children. Like ibuprofen, aspirin, and physical methods (such as fanning), paracetamol aims to provide relief from symptoms and prevent febrile convulsions. Uncertainty exists about the benefits of using it to treat fever in children. ⋯ Trial evidence that paracetamol has a superior antipyretic effect than placebo is inconclusive. There is limited evidence that there is no difference between the antipyretic effect of paracetamol and physical methods. Data on adverse events in these trials were limited. Establishing standard outcomes will help comparisons between studies and meta-analysis.

ReviewPre-operative autologous donation for minimising perioperative allogeneic blood transfusion.
Public concerns regarding the safety of transfused blood have prompted re-consideration of the indications for the transfusion of allogeneic red cells (blood from an unrelated donor), and a range of techniques designed to minimise transfusion requirements. ⋯ Although the trials of PAD showed a reduction in the need for allogeneic blood the methodological quality of the trials was poor and the overall transfusion rates (allogeneic and/or autologous) in these trials were high, and were increased by recruitment into the PAD arms of the trials. This raises questions about the true benefit of PAD. In the absence of large, high quality trials using clinical endpoints, it is not possible to say whether the benefits of PAD outweigh the harms.

ReviewAmbulatory versus conventional methods for monitoring blood pressure during pregnancy.
Hypertensive disorders are among the most common medical complications of pregnancy and a leading cause of maternal and perinatal morbidity and mortality world-wide. Blood pressure measurement plays a central role in the screening and management of hypertension during pregnancy. In recent years the validity of conventional (clinic) blood pressure measurement has been questioned and efforts have been made to improve the technique with ambulatory automated devices that provide a large number of measurements over a period of time, usually a 24-hour period. ⋯ There is no randomised controlled trial evidence to support the use of ambulatory blood pressure monitoring during pregnancy. Randomized trials with adequate design and sample sizes are needed to evaluate the possible advantages and risks of ambulatory blood pressure monitoring during pregnancy, in particular in hypertensive pregnant women. These trials should evaluate not only clinical outcomes, but also use of health care resources and women's views.

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.
