BACKGROUND After a drought in February, 1996, all 126 patients in a haemodialysis unit in Caruaru, north-east Brazil, developed signs and symptoms of acute neurotoxicity and subacute hepatotoxicity following the use of water from a lake with massive growth of cyanobacteria (blue-green algae). 60 patients died. METHODS Besides recording clinical details… (More)
BACKGROUND The commonest cause of end-stage renal failure (ESRF) in children and young adults is congenital malformation of the kidney and urinary tract. In this retrospective review, we examine whether progression to ESRF can be predicted and whether treatment with angiotensin converting enzyme inhibitors (ACEI) can delay or prevent this. METHODS We… (More)
BACKGROUND We highlight a chronic inflammatory disease we call 'hyper-IgG4 disease', which has many synonyms depending on the organ involved, the country of origin and the year of the report. It is characterized histologically by a lymphoplasmacytic inflammation with IgG4-positive cells and exuberant fibrosis, which leaves dense fibrosis on resolution. A… (More)
In a random sample of 40 healthy people, 35% showed evidence of Tropheryma whippelii DNA in their saliva. Consistent detection of T. whippelii DNA on repeated sampling suggests that this organism can be an oral commensal.
Patients with severe viral infections such as Lassa or Ebola may be denied adequate laboratory investigations because of justifiable fears among laboratory staff. This study in monkeys was designed to provide comprehensive haematological and biochemical monitoring in a contained environment during all stages of Ebola infection. Marked neutrophilia,… (More)
A 49-year-old man undergoing maintenance hemodialysis three times weekly for the past 14 years due to presumed hypertensive nephrosclerosis was submitted to a chest x-ray during evaluation of flu-like symptoms that resolved 3 days later. The chest x-ray disclosed interstitial infiltrates and bilateral apical opacities (Figure 1). There was no history of… (More)
In uremia, diminished reactive oxygen intermediate production is an important consequence of impaired neutrophil function. The effects of guanidino compounds, which are known uremic toxins, on neutrophil reactive oxygen intermediate production in vitro were studied. Neutrophils from healthy volunteers were exposed for 3 h to individual guanidino compounds… (More)
