ReviewAnti-D administration after childbirth for preventing Rhesus alloimmunisation.
The development of Rh immunisation and its prophylactic use since the 1970s has meant that severe Rhesus D (RhD) alloimmunisation is now rarely seen. ⋯ Anti-D, given within 72 hours after childbirth, reduces the risk of RhD alloimmunisation in Rhesus negative women who have given birth to a Rhesus positive infant. However the evidence on the optimal dose is limited.

Extracts of the plant Echinacea (family Compositae) are widely used in some European countries and the USA for upper respiratory tract infections. ⋯ The majority of the available studies report positive results. However there is not enough evidence to recommend a specific Echinacea product, or Echinacea preparations for the treatment or prevention of common colds.

ReviewOral anticoagulants for preventing stroke in patients with non-valvular atrial fibrillation and no previous history of stroke or transient ischemic attacks.
Non-valvular atrial fibrillation (AF) is associated with an increased risk of stroke. ⋯ Adjusted-dose OAC (achieved INRs between 2-3) reduces stroke as well as disabling/fatal stroke for patients with nonvalvular AF, and these benefits were not substantially offset by increased bleeding among participants in randomized clinical trials. Limitations include relatively short follow-up and imprecise estimates of bleeding risks from these selected participants. For primary prevention in AF patients who have an average stroke rate of 4%/year, about 25 strokes and about 12 disabling fatal strokes would be prevented yearly for every 1000 given OAC.

Enuresis (bedwetting) is a socially disruptive and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. ⋯ Desmopressin rapidly reduced the number of wet nights per week, but there was some evidence that this was not sustained after treatment stopped. Comparison with alternative treatments suggested that desmopressin and tricyclics had similar clinical effects, but that alarms produced more sustained benefits. However, based on the available evidence, these conclusions can only be tentative. There was some evidence of minor side effects of desmopressin in the included trials, such as nasal irritation and nose bleeds. However, the risk of water intoxication associated with over-drinking before bedtime has been reported. Patients and their families need to be warned of potential adverse effects and advise

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.
