ReviewTreatment for spasticity in amyotrophic lateral sclerosis/motor neuron disease.
Spasticity commonly affects patients with motor neuron disease and it is likely to contribute to worsening muscle dysfunction, increased difficulty with activities of daily living and deteriorating quality of life. ⋯ Individualized, moderate intensity, endurance type exercises for the trunk and limbs may help to reduce spasticity in motor neuron disease. No other medical, surgical or alternative treatment and therapy has been evaluated in a randomized fashion in this patient population.

Thrombolytic therapy is a useful tool in the management of acute peripheral arterial ischaemia. Fibrinolytic drugs are used to disperse blood clot to clear arterial occlusion. A variety of techniques are used to deliver these agents. ⋯ Implications for practice Thrombolysis should be reserved for patients with limb threatening ischaemia, due to the high risk of haemorrhage or death. Greater benefit is seen when the thrombolytic agent is delivered into the thrombus. Systemic intravenous thrombolysis is less effective than intra-arterial thrombolysis and is associated with an increase in bleeding complications. 'High dose' and 'forced infusion' techniques, or adjunctive agents such as platelet glycoprotein IIb/IIIa inhibitors may speed up thrombolysis, but these are not accompanied by lower amputation rates or a decreased need for adjunctive endovascular or surgical procedures. 'Low dose continuous infusion', following initial lacing of the thrombus with a high dose of the thrombolytic agent, is the least labour intensive technique. Implications for research Only large multicentre trials with carefully controlled inclusion criteria will be sufficiently powerful to demonstrate genuine benefit for a particular thrombolytic regime.

ReviewTumor necrosis factor-alpha antibody for induction of remission in Crohn's disease.
Crohn's disease may be refractory to conventional treatments such as corticosteroids, enteral nutrition and immuno-suppressive agents. A number of patients with the disease may also become steroid-dependent leading to increased risk of developing steroid-related adverse effects. Recent studies suggest that TNF-a blocking agents may be effective in inducing remission in Crohn's disease. ⋯ Evidence from one randomized controlled trial suggests that a single infusion of infliximab may be effective for induction of remission in Crohn's disease. Based on this study, we can recommend a dose of 5 mg/kg. There is also some evidence that CDP571 may be effective in inducing remission in Crohn's disease. We did not find any evidence that supports the use of etanercept in Crohn's disease. The period of follow up for the patients in these studies was probably too short to allow adequate assessment of recently reported serious adverse effects such as tuberculosis and lymphoma.

Anticholinergic agents such as ipratropium bromide are sometimes used in the treatment of chronic asthma. They effect bronchodilation and have also been used in combination with beta2-agonists in the management of chronic asthma. ⋯ Overall this review provides no justification for routinely introducing anticholinergics as part of add-on treatment for patients whose asthma is not well controlled on standard therapies. This does not exclude the possibility that there may be a sub-group of patients who derive some benefit and a trial of treatment in individual patients may still be justified. The role of long term anticholinergics such as tiotropium bromide has yet to be established in patients with asthma and any future trials might draw on the messages derived from this review.

Treatment of cerebral sinus thrombosis with thrombolytics has been reported in cases with a deteriorating clinical course despite anticoagulant therapy. The rationale of this treatment is to promote rapid recanalisation of the occluded sinus. ⋯ There is currently no available evidence from randomised controlled trials regarding the efficacy or safety of thrombolytic therapy in dural sinus thrombosis. A randomised controlled trial is justified to test this therapy especially in patients predicted to have a poor prognosis.
