Patients with isolated supratentorial brain tumours, presumed to be primary on imaging, have two surgical management options - biopsy or resection. Surgical opinions appear to be equally divided when considering the relative risks and benefits of these two procedures. ⋯ Given that no qualifying studies were identified and because this is an important issue, both in terms of patient risk and benefit and health economics, the author feels it important to conduct a randomised controlled trial in this subject.

Neuroleptic drugs are controversial treatments in dementia, with evidence accumulating that they may hasten clinical decline. Despite these concerns, they are commonly prescribed for elderly and demented patients. Thioridazine, a phenothiazine neuroleptic, is one of the most commonly prescribed. It has often been a preferred agent because it is thought to produce relatively less frequent motor side effects. The drug has significant sedative effects, and it is thought that these are the main mechanism of action in calming and controlling the patient. However, pharmacologically, it also has marked anticholinergic properties that could potentially have a detrimental effect on cognitive function. ⋯ Very limited data are available to support the use of thioridazine in the treatment of dementia. If thioridazine were not currently in widespread clinical use, there would be inadequate evidence to support its introduction. The only positive effect of thioridazine when compared to placebo is the reduction of anxiety. When compared to placebo, other neuroleptics, and other sedatives it has equal or higher rates of adverse effects. Clinicians should be aware that there is no evidence to support the use of thioridazine in dementia, and its use may expose patients to excess side effects.

ReviewKinesthetic stimulation versus theophylline for apnea in preterm infants.
Apnea of prematurity may lead to hypoxemia and bradycardia requiring resuscitative measures being instituted. Many treatments have been used in infants with apnea of prematurity, such as theophylline. Kinesthetic stimulation, which uses various forms of oscillating mattress, might also prevent apnea without using a standard drug such as theophylline. ⋯ The results of this review should be treated with caution. Theophylline has been shown in one small study to be superior to kinesthetic stimulation at treating clinically important apnea of prematurity. There are currently no clear research questions regarding the comparison of methylxanthines and kinesthetic stimulation to treat apnea of prematurity.

Pre-eclampsia is a relatively common complication of pregnancy. Anticonvulsants are used in the belief they help prevent eclamptic fits and subsequent poor outcomes for mother and infant. ⋯ There is not enough evidence to establish the benefits and hazards of anticonvulsants for women with pre-eclampsia. If an anticonvulsant is used, magnesium sulphate appears to be the best choice.

Heavy menstrual bleeding (HMB) is an important cause of ill health in women. Medical therapy, with the avoidance of possibly unnecessary surgery, is an attractive treatment option. A wide variety of medications are available to reduce heavy menstrual bleeding but there is considerable variation in practice and uncertainty about the most appropriate therapy. Plasminogen activators are a group of enzymes that cause fibrinolysis (the dissolution of clots). An increase in the levels of plasminogen activators has been found in the endometrium of women with heavy menstrual bleeding compared to those with normal menstrual loss. Plasminogen activator inhibitors (antifibrinolytic agents) have therefore been promoted as a treatment for heavy menstrual bleeding. There has been a reluctance to prescribe tranexamic acid due to possible side effects of the drugs such as an increased risk of thrombogenic disease (deep venous thrombosis). Long term studies in Sweden, however, have shown that the rate of incidence of thrombosis in women treated with tranexamic acid is comparable with the spontaneous frequency of thrombosis in women. ⋯ Antifibrinolytic therapy causes a greater reduction in objective measurements of heavy menstrual bleeding when compared to placebo or other medical therapies (NSAIDS, oral luteal phase progestagens and ethamsylate). This treatment is not associated with an increase in side effects compared to placebo, NSAIDS, oral luteal phase progestagens or ethamsylate. Flooding and leakage and sex life is significantly improved after tranexamic acid therapy when compared with oral luteal progestogens but no other measures of quality of life were assessed. No study has used resource cost as an outcome. There are no data available within randomised controlled trials which record the frequency of thromboembolic events.
