All 13 patients with neurofibromatosis 2 (NF2) who presented over a period of 17 years at the Institute of Neurological Sciences, Glasgow were reviewed and compared to patients with sporadic vestibular schwannomas. The NF2 patients presented at a younger age than those with sporadic vestibular schwannomas. A significant number had normal pure tone(More)
Exposure of rats to an open-field results in a rapid rise in body temperature. Fifty-four percent of this rise in body temperature was blocked by intracerebroventricular administration of the antipyretic drug sodium salicylate. Intraperitoneal administration of indomethacin, a potent blocker of prostaglandin production, also attenuated the stress-induced(More)
Pathological alterations of the cochlea were studied in three different deaf animal (cat) populations. The ototoxic drug neomycin sulfate, was administered in one experimental series by direct infusion into the cochlear perilymph; a second group was given a series of intramuscular injections of the drug; and in a third experiment a mechanical lesion was(More)
A consensus conference on neurofibromatosis 2 (NF2) was held in 2002 at the request of the United Kingdom (UK) Neurofibromatosis Association, with particular emphasis on vestibular schwannoma (VS) surgery. NF2 patients should be managed at specialty treatment centres, whose staff has extensive experience with the disease. All NF2 patients and their families(More)
OBJECTIVE To produce a reliable objective method of assessing the House-Brackmann (H-B) and regional grades of facial palsy with the results produced and presented in a time and manner suitable for a routine clinical setting. STUDY DESIGN Analysis of video pixel data using artificial neural networks (ANNs). SETTING Tertiary-referral neuro-otologic(More)
Facial paralysis is the loss of voluntary muscle movement of one side of the face. A quantitative, objective, and reliable assessment system would be an invaluable tool for clinicians treating patients with this condition. This paper presents a novel framework for objective measurement of facial paralysis. The motion information in the horizontal and(More)
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmological origin. It should carry unique signatures from the earliest epochs in the evolution of the Universe, inaccessible to standard astrophysical observations. Direct measurements of(More)
We describe a patient who developed palatal tremor and presented with ear clicks that appeared to originate from activity of the levator veli palatini and not the tensor veli palatini. This was treated with botulinum toxin. We discuss the motor innervation of the palate in the context of our case, our findings in terms of classification, and how the lower(More)
