Text:17020434:optimising stroke prevention in non-valvular atrial fibrillation. atrial fibrillation is associated with substantial morbidity and mortality. pooled data from trials comparing antithrombotic treatment with placebo have shown that warfarin reduces the risk of stroke by 62%, and that aspirin alone reduces the risk by 22%. overall, in high-risk patients, warfarin is superior to aspirin in preventing strokes, with a relative risk reduction of 36%. ximelagatran, an oral direct thrombin inhibitor, was found to be as efficient as vitamin k antagonist drugs in the prevention of embolic events, but has been recently withdrawn because of abnormal liver function tests. the active-w (atrial fibrillation clopidogrel trial with irbesartan for prevention of vascular events) study has demonstrated that warfarin is superior to platelet therapy (clopidogrel plus aspirin) in the prevention af embolic events. idraparinux, a factor xa inhibitor, is being evaluated in patients with atrial fibrillation. angiotensin-converting enzyme inhibitors and angiotensin ii receptor-blocking drugs hold promise in atrial fibrillation through cardiac remodelling. preliminary studies suggest that statins could interfere with the risk of recurrence after electrical cardioversion. finally, percutaneous methods for the exclusion of left atrial appendage are under investigation in high-risk patients.

Text:1009330:further studies on effects of irrigation solutions on rat bladders. further studies on the effects of certain irrigating fluids on the rat bladder for 18 hours are reported. the results have shown that the degradation product p-choloroaniline is not a significant factor in chlorhexidine-digluconate associated erosive cystitis. a high percentage of kanamycin-colistin and povidone-iodine irrigations were associated with erosive cystitis and suggested a possible complication with human usage. picloxydine irrigations appeared to have a lower incidence of erosive cystitis but further studies would have to be performed before it could be recommended for use in urological procedures.
