Donor lymphocyte infusions (DLI) can induce remissions in patients who have relapsed after allogeneic bone marrow transplantation (BMT). However, DLI frequently also result in significant acute and/or chronic graft-versus-host disease (GVHD). Several clinical and experimental lines of evidence have suggested that CD8(+) T cells play a critical role in the… (More)
A covert monitoring procedure was employed to encourage a stroke patient to 'self-monitor' two parameters of her walking performance outside the physiotherapy department. The patient was aware that her walking would be monitored, but not of the identity of the monitors. After 12 days of covert monitoring, the two gait parameters, width of base and step… (More)
AIMS To determine whether unilateral cataract causes a pathological Pulfrich's phenomenon. METHODS 29 subjects with unilateral cataract and contralateral pseudophakia were assessed on their ability to perceive the Pulfrich phenomenon. Using a computer generated pendulum image, and graded neutral density filters, a series of forced choice trials were… (More)
The effect on macular function of the wavelength of laser light used to treat proliferative diabetic retinopathy was studied. Thirty-six eyes of 25 patients received panretinal photo-coagulation according to a standardised protocol and before and at intervals after the treatment were tested by a battery of macular function tests. Each eye was randomly… (More)
26 cases of corneal opacity after cataract surgery occurred in a period of 2 weeks in one surgical unit. Cases occurred after a change in source of intraocular hypromellose solution and only among patients in whom the new product had been used.
Colour doppler imaging and conventional spectral doppler/B-mode techniques were used to detect and quantify rectus muscle movement during voluntary saccades. A velocity gradient was evident in all muscles studied--low velocities near the muscle origin at the back of the orbit increasing linearly to a maximum near the muscle insertion on the globe. A… (More)
A case of a 78-year-old female with bilateral groin prevascular herniae following an emergency aorto-uniiliac EVAR and femoro-femoral bypass for a ruptured abdominal aortic aneurysm is presented. Primary repair of the herniae was achieved using a preperitoneal approach. The case emphasises a safe approach to dealing with this rare complication.
