Circulating immune complexes in Buerger's disease. Endarteritis obliterans in young men.

Auto-antibodies such as anti-elastin, anti-collagen, anti-nuclear and anti-arterial, circulating immune complexes, and cellular responses to collagen I and III are known to be present in Buerger's disease (EO). Deposits of IgG, C3 and C4 have also been found in the vascular lesions of endarteritis obliterans (EO) in young men. The purpose of this study was to correlate clinical evidence of vascular disease with the presence of the circulating immune complexes. Thirty-three patients suffering from Buerger's disease (EO), 20 patients suffering from atherosclerosis (AT) and 20 normal controls (Norm) were studied. All were male, heavy smokers, and age-matched. Five techniques were used: direct nephelometry, nephelometry with protamine, two polyethyleneglycol precipitation methods (PegIgG and PegC4), and an immuno-enzymatic C1q fixation test (C1qE). The results seem to confirm the presence of circulating immune complexes in peripheral arterial disease in young men who are heavy smokers, particularly those suffering from EO.

[Interpretation of blood culture results (author's transl)].

The most important problem of blood culture results interpretation is represented by contaminations. The Author reviews the different criteria differentiating contamination from bacteremia. Particularly he discusses the importance of type of organism isolated; of number of blood cultures taken from each patient; of pour-plate culture results; of antibodies production towards the organism isolated.

[Epidemiological and bacteriological study on the outbreak of gastroenteritis due to Escherichia coli 0111:B4 which occured in hospital environment].

The Authors report the results of the bacteriological researches carried out during an outbreak of gastroenteritis from E. coli O111:B4 having concerned, in 6 months, 40 infants of the pediatric ward at Legnano's Hospital. The researches clearly demonstrate the need for a strict control, particularly in the pediatric and neonatal wards, so as to make possible a swift identification of the gastroenteric syndromes due to E. coli strains which cause enteritis. The gravity of the symptomatology, the likelihood of the infections's spreading within the hospital and the considerable resistance to antibiotics of the strains in question are all factors which make this type of infection one particularly to be feared in hospitals.
