We describe the successful use of methadone in the restoration of sedation and provision of analgesia in two morphine-tolerant, paediatric patients who had suffered significant thermal injuries and were undergoing mechanical ventilation. Both patients had exhibited escalating requirements for sedative drugs while undergoing ventilation yet remained(More)
OBJECTIVES The aim of the present study was to evaluate the efficacy of an electric toothbrush with a specially designed orthodontic brush head compared with a manual toothbrush in controlling plaque and gingivitis in patients with fixed orthodontic appliances over an 8-week period in a dental practice setting. METHODS This was a randomised controlled,(More)
Serum ferritin concentration has been compared with semi-quantitative histochemical estimates of bone marrow iron deposits in 60 anaemic patients with rheumatoid arthritis. There was considerable variation in the visual assessment of iron stores made by different observers. Serum ferritin appears to be a particularly sensitive index of iron status when(More)
BACKGROUND Protein-energy wasting is common in patients on maintenance hemodialysis and is strongly associated with poor quality of life and mortality. However, clinical assessment of protein-energy wasting remains difficult. Predialysis creatinine levels are associated with mortality risk but may be influenced by both muscle mass and dialysis dose. This(More)
Thirty anaemic patients with active rheumatoid arthritis were each given 800 mg of iron , as iron dextran, intramuscularly over an interval of four weeks. The haemoglobin concentration rose significantly within two months in 26 of the patients but this was followed by a significant fall to the pre-treatment level nine months after treatment. The response to(More)
The effectiveness of prochlorperazine buccal as an anti-emetic for the prevention of post-operative nausea and vomiting in patients using intravenous patient-controlled analgesia with morphine following abdominal hysterectomy has been assessed in a randomized, double-blind, placebo-controlled study. Forty-nine female patients participated with 26 allocated(More)
Ten patients with active rheumatoid arthritis were given a total dose infusion of iron dextran for anaemia. One had an immediate anaphylactoid reaction; the other nine had a brief exacerbation of arthralgia and joint dysfunction of up to seven days' duration. The erythrocyte sedimentation rate rose by an average of 23 mm. in one hour (Westergren), but this(More)
In an open, controlled, multi-centre clinical field trial, seven 'naturally occurring' outbreaks of acute febrile (rectal temperature > or = 39.5 degrees C) respiratory disease in housed calves were treated with a single antimicrobial agent, and either the non-steroidal anti-inflammatory drug (NSAID) carprofen (n = 95) or flunixin meglumine (n = 92) on an(More)
BACKGROUND/AIMS The hypothesis that chronic alcohol ingestion potentiates iron-associated liver injury was investigated in the 'carbonyl iron-overload rat model'. METHODS Newborn male and female Wistar-Furth rats (seven per group) were used to investigate iron-alcohol interaction over a 26-week period. Groups 1 and 2 were iron loaded from birth, while the(More)
