Fifty Foley bladder catheters that had been indwelling for periods ranging from 3 to 83 days (mean 35 days) were examined for the presence of bacterial biofilm. Scanning electron microscopy on freeze-dried cross-sections and fixed, critical point-dried longitudinal sections revealed biofilm formation on the luminal surfaces of 44 of the catheters. Culture(More)
Tic douloureux involving the glossopharyngeal nerve is rare and when it does occur probably often involves the vagus nerve as well. Many cases are undoubtedly not recognized, and yet the condition responds favourably and permanently to intracranial section of the glossopharyngeal nerve and upper filaments of the vagus nerve. We therefore propose to review(More)
Pituitary neoplasms in primary myxoedema are rare and previously reported cases have mostly been described as chromophobe adenomas. None of them were subjected to modern methods of study. A 26 year-old woman with untreated primary hypothyroidism developed a pituitary tumour which produced bitemporal hemianopsia. Histochemical and ultrastructural studies(More)
An increased risk of bladder cancer is a recognized complication in spine-injured patients undergoing long-term urethral catheterization to preserve renal function. Aerobic cultures from 28 of 30 paraplegic patients showed complex bacterial flora containing nitrate-reducing organisms (Escherichia coli, Proteus and Klebsiella spp.). Urine samples from 29(More)
A collection of 70 strains of Escherichia coli from urinary tract infections in spine-injured patients undergoing long-term bladder catheterization were tested for characteristics that have been associated with the ability to produce pyelonephritis. The incidence of the virulence factors were: mannose-resistant haemagglutinins (30%), P-fimbriae (17%),(More)
The activity of chlorhexidine, acetic, lactic and mandelic acids were examined against biofilms of Escherichia coli established on silicone discs and against the test strain growing in suspension in urine. The results showed that the concentrations of chlorhexidine and acetic acid normally used for bladder instillations to control infections in patients(More)
The activity of chlorhexidine, mandelic acid and a mandelic/lactic mixture were tested against biofilms of four species of gram-negative nosocomial organisms that commonly infect the catheterized urinary tract. Cells growing on silicone discs were exposed to concentrations of agents used in bladder instillation. Citrobacter diversus biofilms proved to be(More)
was pain free and walking well on a pylon before receiving a definite prosthesis. Examination of the amputation specimen (Fig. 1) showed an ill-defined red tumour lying deep to the Achilles tendon, tumour nodules mingling with adjacent adipose tissue. A number of separate tumour masses were also present in both superficial and deep fascia, the most proximal(More)
A training and monitoring system has been developed to train spinal cord injured patients to relieve pressure intermittently from ischium while sitting in wheelchairs. The system automates the training of wheelchair push-ups based on certain conditioning principles. The system reminds the patient to do a push-up of a specified duration and at specified(More)
