Two recent epidemiological studies have reported that children using non-feather pillows suffered from more frequent episodes of wheeze than those using feather pillows ⋯ Whilst recent epidemiological studies suggest that feather bedding is associated with less frequent wheeze than man-made fibre fillings, the evidence currently available is insufficient to assess the clinical benefits of feather bedding in the management of asthma.

Traumatic brain injury is a leading cause of premature death and disability. Post-traumatic membrane lipid peroxidation has been proposed as one mechanism leading to secondary brain damage following head injury. Aminosteroids have been shown to inhibit lipid peroxidation in laboratory animals and have the potential to improve outcome following head injury. ⋯ There is no evidence to support the routine use of aminosteroids in the management of traumatic head injury. On the basis of the existing evidence from randomised trials of aminosteroids in head injury it is not possible to refute the possibility of moderate but potentially clinically important benefits or harms. A further randomised controlled trial of tirilazad mesylate with 1156 participants has been completed, the results of which should become available in the near future.

Lung volume reduction surgery (LVRS) has been re-introduced for treating patients with severe diffuse emphysema. ⋯ There is no randomised controlled trial evidence concerning the efficacy of LVRS for diffuse emphysema compared to optimal conservative medical therapy. Stapling is more effective than laser resection and has a lower complication rate. LVRS should not be applied routinely until results of large trials currently underway become available.

Post-partum endometritis, which is more common after cesarean section, occurs when vaginal organisms invade the endometrial cavity during labour and delivery. Antibiotic treatment is warranted. ⋯ The combination of gentamicin and clindamyin is appropriate for the treatment of endometritis. Regimens with activity against penicillin resistant anaerobic bacteria are better than those without. There is no evidence that any one regimen is associated with fewer side effects. Once uncomplicated endometritis has clinically improved with intravenous therapy, oral therapy is not needed.

There are two reasons to believe anxiolytics might help in smoking cessation. Anxiety may be a symptom of nicotine withdrawal. Second, smoking appears to be due, in part, to deficits in dopamine, serotonin and norepinephrine, all of which are increased by anxiolytics and antidepressants. ⋯ There is no consistent evidence that anxiolytics aid smoking cessation, but the available evidence does not rule out a possible effect.
