Clinical Reviews.
Argirios Argiriou:
Summary points:
Cataract is not always due to ageing.
Cataract symptoms vary depending on type of cataract and the patient's lifestyle and visual requirements.
Cataract surgery in the developed world is undertaken when the benefit from removal of symptoms outweighs the small risks attached to modern surgery.
After surgery, 85-90% of patients should obtain vision sufficient to meet the requirements for driving in most countries.
New implant technology promises to improve the image quality and conquer the problems of presbyopia (the need for spectacles to read).
Posterior capsule opacification 2-5 years after surgery is still a problem in many cases.

Summary points:
Deep vein thrombosis is an important cause of morbidity and mortality.
Clinical diagnosis is unreliable.
Screening investigations include D-dimer tests and plethysmographic techniques.
Definitive diagnosis is usually by venography or ultrasonography.
Initial treatment is with heparin—unfractionated or low molecular weight—followed by oral anticoagulation.
Outpatient treatment of deep vein thrombosis is safe.

Treatment of deep vein thrombosis:
The standard initial management of deep vein thrombosis has traditionally meant admission to hospital for continuous treatment with intravenous unfractionated heparin. Treatment then continued with a transition to long term use of oral anticoagulants (vitamin K antagonists).
Recently a change has taken place, and low molecular weight heparins are being used.
Guidelines prepared by the haemostasis and thrombosis task force recommend that patients receive heparin for at least four days and treatment should not be discontinued until the international normalised ratio has been in the therapeutic range for two consecutive days. According to these guidelines, a patient with a first episode of a proximal vein thrombosis should receive anticoagulants for six months, with a target international normalised ratio of 2.5. The issue of length of anticoagulation is still under debate.

Elastic compression stockings:
Patients with a deep vein thrombosis should wear compression stockings as the rate of post-thombotic syndrome may be reduced. In one study of 194 patients (with a first episode of proximal deep vein thrombosis) the rate of post thrombotic syndrome was reduced by 50% if graded compression stockings were used.

Anticoagulation for three versus six months in patients with deep vein thrombosis or pulmonary embolism, or both: randomised trial.

Conclusion: For patients in the UK with deep vein thrombosis or pulmonary embolism and no known risk factors for recurrence, there seems to be little, if any, advantage in increasing the duration of anticoagulation from three to six months. Any possible advantage would be small and would need to be judged against the increased risk of haemorrhage associated with the longer duration of treatment with warfarin.
