Chest radiography is widely used during the management of acute lower respiratory infections, but the benefits are unknown. ⋯ There is no evidence that chest radiography improves outcome in outpatients with acute lower respiratory infection. The findings do not exclude a potential effect of radiography, but the potential benefit needs to be balanced against the hazards and expense of chest radiography. The findings apply to outpatients only.

ReviewSpinal fixation surgery for acute traumatic spinal cord injury.
If the spine is unstable following traumatic spinal cord injury (SCI), surgical fusion and bracing may be necessary to obtain vertical stability and prevent re-injury of the spinal cord from repeated movement of the unstable bony elements. It has been suggested that this spinal fixation surgery may promote early rehabilitation and mobilisation. ⋯ The current evidence does not enable conclusions to be drawn about the benefits or harms of spinal fixation surgery in patients with traumatic SCI. Well-designed, prospective experimental studies with appropriately matched controls are needed.

ReviewEarly versus delayed laparoscopic cholecystectomy for biliary colic.
Biliary colic is one of the commonest indications for laparoscopic cholecystectomy. Laparoscopic cholecystectomy involves several months of waiting if performed electively. However, patients can develop life-threatening complications during this waiting period. ⋯ Based on evidence from only one high-bias risk trial, it appears that early laparoscopic cholecystectomy (< 24 hours of diagnosis of biliary colic) decreases the morbidity during the waiting period for elective laparoscopic cholecystectomy, decreases the rate of conversion to open cholecystectomy, decreases operating time, and decreases hospital stay. Further randomised clinical trials are necessary to confirm or refute this finding.

Seizures are poorly controlled in many people with epilepsy despite adequate current antiepileptic treatments. There is increasing interest in alternative therapies such as acupuncture; however, it remains unclear whether the existing evidence is rigorous enough to support the use of acupuncture. This is an update of a Cochrane review first published in 2006. ⋯ The current evidence does not support acupuncture as a treatment for epilepsy.

ReviewWITHDRAWN: Luteal phase support in assisted reproduction cycles.
The aspiration of the granulosa cells that surround the oocyte and the use of gonadotropin releasing hormone agonists (GnRHa) during assisted reproduction technology (ART) treatment can interfere with the production, during the luteal phase, of progesterone, which is necessary for successful implantation of the embryo. Providing hormonal supplementation during the luteal phase with either progesterone itself, or human chorionic gonadotropin (hCG), which stimulates progesterone production, may improve implantation and, thus, pregnancy rates. ⋯ Luteal phase support with hCG or progesterone after assisted reproduction results in an increased pregnancy rate. hCG does not provide better results than progesterone, and is associated with a greater risk of OHSS when used with GnRHa. The optimal route of progesterone administration has not yet been established.
