ReviewAntioxidant vitamin and mineral supplementation for preventing age-related macular degeneration.
Some observational studies have suggested that people who eat a diet rich in antioxidant vitamins (carotenoids, vitamins C and E) or minerals (selenium and zinc) may be less likely to develop age-related macular degeneration. ⋯ There is no evidence to date that people without age-related macular degeneration should take antioxidant vitamin and mineral supplements to prevent or delay the onset of the disease. The results of five large ongoing trials are awaited.

Typical antipsychotic drugs are widely used as the first line treatment for people with schizophrenia. However, the atypical class of antipsychotic drugs is making important inroads into this approach. 'Atypical' is a term widely used to describe some antipsychotics which have a low propensity to produce movement disorders, sedation and raised serum prolactin. There is some suggestion that the different adverse effect profiles of the atypical antipsychotic group make them more acceptable to people with schizophrenia. Molindone has a similar profile to quetiapine (a novel atypical antipsychotic), with very low binding to all receptors. Some authors have suggested that molindone is safer than other 'typical' antipsychotics in that extrapyramidal adverse effects are not usually seen at clinically effective antipsychotic doses and that it should therefore be classed as an atypical antipsychotic. ⋯ The strength of the evidence relating to this compound is limited, owing to small sample size, poor study design, limited outcomes and incomplete reporting. Molindone may be an effective antipsychotic; however, its adverse effect profile does not differ significantly from that of typical antipsychotics, apart from the event of weight loss. At present there is no evidence to suggest that it may have an atypical profile.

ReviewSurgical interruption of pelvic nerve pathways for primary and secondary dysmenorrhoea.
Dysmenorrhoea is the occurrence of painful menstrual cramps of uterine origin and is a very common gynaecological complaint. Medical therapy for dysmenorrhoea includes oral contraceptive pills (OCP) and nonsteroidal anti-inflammatory drugs (NSAIDS) which both act by suppressing prostaglandin levels. While these treatments are very successful there is still a 20-25% failure rate and surgery has been an option for cases of dysmenorrhoea that fail to respond to medical therapy. Uterine nerve ablation (UNA) and presacral neurectomy (PSN) are two surgical treatments that have become increasingly utilised in recent years. These procedures both interrupt the majority of the cervical sensory nerve fibres, thus diminishing uterine pain. Uncontrolled studies have supported the use of these procedures for primary dysmenorrhoea however both operations only partially interrupt some of the cervical sensory nerve fibres in the pelvic area; therefore dysmenorrhoea associated with additional pelvic pathology may not always benefit from this type of surgery. ⋯ There is insufficient evidence to recommend the use of nerve interruption in the management of dysmenorrhoea, regardless of cause. Future RCTs should be undertaken.

Acute traumatic brain injury is a major cause of death and disability. Calcium channel blockers have been used in an attempt to prevent cerebral vasospasm after injury, maintain blood flow to the brain and so prevent further damage. ⋯ This systematic review of randomized controlled trials of calcium channel blockers in acute traumatic head injury patients shows that considerable uncertainty remains over their effects. The effect of nimodipine in a subgroup of brain injury patients with subarachnoid haemorrhage shows a beneficial effect, though the increase in adverse reactions suffered by the intervention group may mean that the drug is harmful for some patients.
