Determinants of treatment duration in the prevention of recurrent venous thromboembolism: a protocol for a balanced vignette experiment.

Introduction: Venous thromboembolism (VTE) is a condition that annually occurs in approximately 1‰ of the world's population. Patients who have already had a VTE are at elevated risk for a recurrent VTE. Recurrent events increase the risk of long-term sequelae and can be fatal.

Photodynamic therapy versus topical imiquimod versus topical fluorouracil for treatment of superficial basal-cell carcinoma: a single blind, non-inferiority, randomised controlled trial.

Background: Superficial basal-cell carcinoma is most commonly treated with topical non-surgical treatments, such as photodynamic therapy or topical creams. Photodynamic therapy is considered the preferable treatment, although this has not been previously tested in a randomised control trial. We assessed the effectiveness of photodynamic therapy compared with imiquimod or fluorouracil in patients with superficial basal-cell carcinoma.
