BACKGROUND Postoperative pain after total hip arthroplasty (THA) can delay mobilization. This was assessed after intrathecal morphine (ITM) compared with local infiltration analgesia (LIA) using a non-inferiority design. METHODS Eighty patients were recruited in this randomized, double-blind study. ITM 0.1 mg (Group ITM) or periarticular local anaesthetic(More)
Three unrelated severe infections with Streptococcus zooepidemicus occurred in England in 1985. The first patient developed septic arthritis, which has not been recorded before with this organism. The second died with septicaemia, pneumonia and post-streptococcal glomerulonephritis, the only record so far of nephritis following sporadic S. zooepidemicus(More)
The synthetic disaccharide 3-O-alpha-tyvelopyranosyl-alpha-D-mannopyranoside, identical to the O antigen 9 determinant in Salmonella, covalently linked to bovine serum albumin and suspended in Freund complete adjuvant, was used as an immunogen in mice. Antibodies in high titer were formed against the O9 determinant as estimated by a bactericidal assay,(More)
The enzyme-linked immunosorbent assay (ELISA) has been applied to the detection of antibodies against Salmonella O-antigens in human sera. Phenol-water extracted lipopolysaccharides (LPS) from serogroups A (O-antigens 2, 12), B (4, 5, 12) and D (9, 12) were used as antigens. When compared to the tube agglutination method according to Widal employing sera(More)
In our experience, more than half of muscular dystrophy patients show a primary dystrophinopathy. The underlying cause of muscular dystrophy in the vast majority of patients with normal dystrophin is unknown. Recently, a French family with 4 young siblings showing a muscular dystrophy of unknown progression was shown to have a primary deficiency of(More)
Purpose: Recently, solid-state detector is the novel γ-camera to reduce patient’s imaging time and radiation dosage. The aim of this study was to establish the optimal protocol for myocardial perfusion imaging (MPI) using Thallium-201 with a cadmium-zinc-telluride (CZT) cardiac γ-camera. Materials and Methods: 11 patients of coronary artery disease took(More)
A plenum chamber type ventilating system which produces a column of clean filtered air in an orthopaedic operating theatre has been designed using conventional air conditioning equipment. Its performance has been evaluated by carrying out smoke studies, and air velocity studies, and its cleanliness evaluated by bacteriological sampling. Two hundred and(More)
