PURPOSE Well-conducted cancer clinical trials are essential for improving patient outcomes. Unfortunately, only 3% of new cancer patients participate in clinical trials. Barriers to patient accrual in cancer clinical trials must be identified and overcome to increase patient participation. MATERIALS AND METHODS We prospectively tracked factors that(More)
In Asia Pacific countries, lamivudine is used frequently as the sole prophylaxis for hepatitis B virus (HBV) recurrence after liver transplantation due to financial consideration. The aim was to evaluate the long-term outcome of lamivudine monoprophylaxis with adefovir salvage for liver transplantation in chronic hepatitis B. Consecutive chronic hepatitis B(More)
PURPOSE To clarify the clinical features of delayed calcification of hydrogel intraocular lenses (IOLs) based on observation of a large case series. SETTING Ophthalmology department of 2 university teaching hospitals, Hong Kong, China. METHODS The first 44 patients with a known diagnosis of calcified IOL were recruited. Medical and ophthalmic histories(More)
PURPOSE To assess the outcome of patients who underwent instantaneous pars plana vitrectomy for dislocated lens fragments during cataract surgery. METHODS The medical records of 29 patients who underwent immediate pars plana vitrectomy for dislocated lens fragments at the same sitting of phacoemulsification surgery were reviewed. Data including patients'(More)
OBJECTIVE To evaluate the efficacy of endoscopic transnasal orbital decompression alone for thyrotoxic orbitopathy. DESIGN Retrospective review of consecutive procedures. SETTING Tertiary referral otorhinolaryngology centre. PATIENTS Twenty-three eyes of 14 patients. INTERVENTION Endoscopic transnasal orbital decompression. MAIN OUTCOME MEASURES(More)
Transient vision loss may indicate underlying vascular disease, including carotid occlusion and thromboembolism, or it may have a more benign etiology, such as migraine or vasospasm. This review focuses on the differential diagnosis and workup of patients presenting with transient vision loss, focusing on several key areas: the relationship to(More)
The progression of subclavian arterial stenosis and the subsequent formation of collateral pathways serve to alter the pressure gradients in subclavian steal syndrome, altering ipsilateral vertebral artery flow from its normal state to "latent," "transient," and "continuous" steals. A similar altered flow in the carotid arteries can be observed with(More)
Over a 21 month period, 112 patients were seen in the vascular laboratory for evaluation and therapy of possible pseudoaneurysm. Pseudoaneurysm was confirmed by color flow sonographic imaging in 31 patients. Twenty-eight of these patients underwent sonographically monitored extrinsic manual compression to induce thrombosis and subsequent obliteration.(More)
