ReviewBenzo-pyrones for reducing and controlling lymphoedema of the limbs.
Lymphoedema is the accumulation of excess fluid in the body caused by obstruction of the lymphatic drainage mechanisms. It can be caused by a number of factors, including congenital predisposition, parasitic infection or surgery. Lymphoedema is chronic and progressive and affects a significant proportion of the population. The standard treatment regimes include compression hosiery, skin care and exercise. The use of drugs in treatment, particularly benzo-pyrones, has gained favour over the last ten years. Benzo-pyrones, originally developed for use in vascular medicine, are prescribed to reduce vascular permeability and thus the amount of fluid forming in the subcutaneous tissues. Advocates for this treatment method believe that, as a result of reducing filtration, the drugs have some beneficial effect on pain and discomfort in the swollen areas. Proponents also claim that these drugs increase macrophage activity, encouraging the lysis of protein, which in turn reduces the formation of fibrotic tissue in the lymphoedematous limb. ⋯ Meta-analysis was not performed due to the poor quality of the trials. It is not possible to draw conclusions about the effectiveness of Benzopyrones in reducing limb volume, pain, or discomfort in lymphoedematous limbs from these trials.

Besides reversing the underlying cause, the first line treatment for the symptoms of shock is usually the administration of intravenous fluids. If this method is not successful, vasopressors such as dopamine, dobutamine, adrenaline, noradrenaline and vasopressin are recommended. It is unclear if there is a vasopressor of choice, either for the treatment of particular forms of shock or for the treatment of shock in general. ⋯ The current available evidence is not suited to inform clinical practice. We were unable to determine whether a particular vasopressor is superior to other agents in the treatment of states of shock.

ReviewWritten individualised management plans for asthma in children and adults.
Non-adherence to treatment advice is a common phenomenon in asthma and may account for a significant proportion of the morbidity. Comprehensive care that includes asthma education, a written self-management plan and regular review has been shown to improve asthma outcomes, but the contribution of these components has not been established. ⋯ The available trials are too small and the results too few and inconsistent to form any firm conclusions as to the contribution of written self management plans in the known beneficial effects of a comprehensive asthma care programme.

Studies have reported high tumour response rates for platinum-containing regimens in the treatment of women with metastatic breast cancer. ⋯ In view of the significant excess toxicity, lack of progression or survival benefit and the availability of less toxic active agents it is difficult to justify the use of platinum-containing regimens, particularly as first line treatment for women with metastatic breast cancer in routine clinical practice. Ongoing trials are examining the possibility of synergy between platins and trastuzamab, a monoclonal antibody treatment. No randomised trials containing oxalplatin were identified for the present review.

The aim of nicotine replacement therapy (NRT) is to replace nicotine from cigarettes. This reduces withdrawal symptoms associated with smoking cessation thus helping resist the urge to smoke cigarettes. ⋯ All of the commercially available forms of NRT (gum, transdermal patch, nasal spray, inhaler and sublingual tablets/lozenges) are effective as part of a strategy to promote smoking cessation. They increase the odds of quitting approximately 1.5 to 2 fold regardless of setting. The effectiveness of NRT appears to be largely independent of the intensity of additional support provided to the smoker. Provision of more intense levels of support, although beneficial in facilitating the likelihood of quitting, is not essential to the success of NRT.
