In an attempt to establish the characteristics, circumstances leading to infection and development of polyarteritis nodosa (PN) related to hepatitis B virus (HBV), prognostic factors and outcome, and to define the most effective treatment, 66 patients observed between 1972 and 1989 were analyzed. Hepatitis was clinically present in 19/66 patients before PN.(More)
IgG subclasses of anti-double-stranded DNA antibodies were determined in 182 patients with systemic lupus erythematosus. All isotypes were detected, but IgG1 and IgG3 were predominant (62 and 51% of the cases, respectively). An average of 64 +/- 27% was IgG1, 16 +/- 22% IgG2, 16 +/- 19% IgG3 and 4 +/- 10% IgG4. The rank order or frequency was IgG1, IgG3,(More)
OBJECTIVES A key element of medical competence is problem solving. Previous work has shown that doctors use inductive reasoning to progress from facts to hypotheses and deductive reasoning to move from hypotheses to the gathering of confirmatory information. No individual assessment method has been designed to quantify the use of inductive and deductive(More)

Pneumococcal peritonitis presents as a very serious peritonitis and the usual diagnosis that is first made is peritonitis due to appendicitis. Pneumococcal peritonitis(More)
beta-Lipoprotein determination and selective serum protein precipitation with Cetrimonium bromide (Badin's Cetrimonium test) were carried out retroactively (after delivery) on sera selected out of 700 sera collected from women at 4-5 months and 6-7 months of pregnancy. The selected sera were those from 36 women in the first group and 37 in the second group,(More)
In 163 cases uterine activity in labour was measured in 15 minutes periods, thanks to a new monitoring apparatus that works out the sum of the areas of uterine contraction (A U 15). In this way a regular statistical estimation of labour is given in kilopascals x second. The fetal state during labour and at birth is studied as a function of this new(More)
