BACKGROUND Whipple's disease (WD) of the brain without evidence of systemic involvement is a rare illness that is difficult to recognize and potentially life-threatening. AIM To elucidate the clinical features and diagnosis of primary WD of the brain. DESIGN A single case study, with review of published data. METHODS We linked the information about(More)
Three parkinsonian patients are described who independently discovered that their gait was facilitated by inverting a walking stick and using the handle, carried a few inches from the ground, as a visual cue or target to step over and initiate walking. It is suggested that the "inverted" walking stick have wider application in patients with Parkinson's(More)
Pudendal neuropathies are well recognised as part of more generalised peripheral neuropathies; however, focal abnormalities of the pudendal nerve due to cycling-related injuries have been infrequently reported. We describe two patients who developed pudendal neuropathies secondary to pressure effects on the perineum from racing-bicycle saddles. Both were(More)
Six hundred and sixty-one patients with stroke, confirmed by CT scan or at autopsy, were reviewed in order to evaluate the frequency of presentation with altered mental state. Nineteen patients (3%) had presented with delirium, an organic delusional state, the acute onset of dementia, or mania, mimicking psychiatric illness. All had focal cerebrovascular(More)
Visual involvement was assessed in 21 patients with Friedreich's ataxia and in 17 patients with spastic ataxia by neuro-ophthalmic examination and by recording visual evoked responses (VERs). Two thirds of the patients with Friedreich's ataxia had some degree of visual impairment and an abnormal VER, whereas only three of the 17 patients with spastic ataxia(More)
Primary position upbeating nystagmus has been associated clinically with intra-axial brainstem and cerebellar lesions but evidence for more precise localisation to the ponto-mesencephalic and ponto-medullary junctions is accumulating. We report the occurrence of primary position upbeating nystagmus in three patients who had clinical signs of pontine lesions(More)
There is a definite relationship between the vascular type of benign sexual headache and benign exertional headache. Forty five patients with benign vascular sexual headache were reviewed. Twenty seven (60%) experienced benign vascular sexual headache alone and eighteen (40%) had experienced both benign vascular sexual headache and benign exertional(More)
Whole tibialis anterior muscles were removed from a number of dogs and were then reimplanted in the original sites. Microsurgical anastomoses of the major nerve, artery, and vein were performed. Biopsy revealed some minor regenerative changes in the muscle a few weeks after the operation. Electromyographic recordings 6-9 months after implantation showed(More)
Intraneural perineurioma is a rare tumour that affects peripheral nerves and, based on its histological features, may be confused with hereditary motor and sensory neuropathies. Detailed neuropathology, including immunoperoxidase stains and electron microscopy, is vital to distinguish these conditions. We report two patients with intraneural perineurioma(More)
