Malignant hyperthermia (MH) and central core disease (CCD) are autosomal dominant disorders of skeletal muscle. Susceptibility to MH is only apparent after exposure to volatile anesthetics and/or depolarizing muscle relaxants. CCD patients present with diffuse muscular weakness but are also at risk of MH. Mutations in RYR1 (19q13.1), encoding a skeletal(More)
Previous perfusion studies of the rotator cuff have demonstrated an area of hypovascularity in the distal part of the supraspinatus tendon. This has been implicated in the pathogenesis of its rupture. We performed a quantitative histological analysis of the vascularity of the tendons of supraspinatus and infraspinatus. Vessel number, size and the percentage(More)
We studied the arterial anatomy and the effect of four-part fractures on the vascularity of the humeral head, using barium sulphate perfusion of 16 cadaver shoulders. The main arterial supply to the humeral head was via the ascending branch of the anterior humeral circumflex artery and its intraosseous continuation, the arcuate artery. There were(More)
BACKGROUND Malignant hyperthermia (MH) is an inherited, potentially fatal, pharmocogenetic disorder triggered by certain anaesthetic agents. In light of the reported genetic heterogeneity for the disorder and the recent introduction of DNA testing guidelines for the trait, we have assessed the role of the CACNA1S gene in MH susceptibility in UK patients.(More)
Proteinuria, often nephrotic in range, is a recognized paraneoplastic syndrome of solid tumours, with membranous glomerulonephritis (MGN) the most common histopathological lesion seen on renal biopsy. A 56-year-old male was found to have proteinuria on routine medical examination. History, physical and serological evaluation failed to reveal an aetiology(More)
