Those of the ulcerative colitis patients who had been on sulphasalazine treatment continued that treatment during the trial (101 patients). Forty patients were(More)
The value of dynamic sonography as a screening procedure in 84 jaundiced patients was examined and compared with the clinical evaluation of a blind prospective study. The predictive value of the sonographic diagnosis of obstruction was 97% and 84% in nonobstruction. The corresponding values of the clinical distinction were 87% and 92% respectively. The(More)
Two hundred and nine patients consecutively admitted to hospital with a tentative diagnosis of meningitis were screened for complement deficiency by measuring classical and alternative pathway serum haemolytic complement activity and the plasma concentration of C3d.
