BACKGROUND The Contact Heat Evoked Potential Stimulator (CHEPS) utilises rapidly delivered heat pulses with adjustable peak temperatures to stimulate the differential warm/heat thresholds of receptors expressed by Adelta and C fibres. The resulting evoked potentials can be recorded and measured, providing a useful clinical tool for the study of thermal and(More)
Current treatments of neuropathic pain arising from conditions such as nerve injury/compression are only partially effective, and limited in their use by side-effects. p38 mitogen-activated protein kinase (MAPK) is involved in the regulation and synthesis of inflammatory mediators, and is the target for a novel class of cytokine-suppressive(More)
The discovery of transient receptor potential (TRP) receptors has advanced understanding of temperature sensation, and pre-clinical studies have identified TRP as major novel analgesic targets in inflammatory and neuropathic pain states. We systematically investigated the sensory effects and interactions of TRP agonists capsaicin (TRPV1), menthol (TRPM8)(More)
BACKGROUND Intracranial haemorrhage accounts for 30-60 % of all stroke admissions into a hospital, with hypertension being the main risk factor. Presence of intraventricular haematoma is considered a poor prognostic factor due to the resultant obstruction to CSF and the mass effect following the presence of blood resulting in raised intracranial pressure(More)
OBJECTIVE To assess the temporal relationship between skin nerve denervation and regeneration (dermal and intra-epidermal fibres, IENF) and functional changes (CO(2) laser-evoked potentials, LEPs, and quantitative sensory tests, QST) after topical cutaneous application of capsaicin. METHODS Capsaicin (0.075%) was applied to the lateral calf for three(More)
Tumours represent one of the important differential diagnoses that need to be considered while investigating fractures of the small bones of the hand, as this can sometimes be the sole or the first presenting complaint. We conducted a retrospective study of the Scottish Bone Tumour Registry, analysing the records of patients with hand tumours which(More)
BACKGROUND A variation seems to exist between hospitals with regard to the initial radiographic assessment of suspected scaphoid fractures. MATERIALS AND METHODS A survey of all acute hospitals in the West of Scotland was carried out to ascertain the current practice in the assessment of acute scaphoid fractures. Consultant radiologists and consultant(More)
BACKGROUND Endoscopic third ventriculostomy (ETV) is a procedure of choice in the treatment of obstructive hydrocephalus. Neurovascular injury while perforating the ventricular floor can occur when using a conventional probe, especially in patients with a thick and opaque third ventricle floor. The water jet dissection technique can be useful in such cases(More)
The relationship among serum vitamin D metabolites, PTH, and osteocalcin concentrations was investigated in 20 elderly subjects. All except 2 had subnormal 25-hydroxyvitamin D concentrations. Eighteen (90%) had subnormal serum 1,25-dihydroxyvitamin D [1,25-(OH)2D] concentrations, while 8 subjects (40%) had elevated PTH concentrations. There was a highly(More)
We describe 261 peripheral nerve injuries sustained in war by 100 consecutive service men and women injured in Iraq and Afghanistan. Their mean age was 26.5 years (18.1 to 42.6), the median interval between injury and first review was 4.2 months (mean 8.4 months (0.36 to 48.49)) and median follow-up was 28.4 months (mean 20.5 months (1.3 to 64.2)). The(More)
