TRIAL DESIGN Non-inferiority randomized clinical trial. METHODS The COLOR II trial is an ongoing international randomized clinical trial. Currently 27 hospitals from Europe, South(More)
Urine samples from 141 consecutive patients referred for investigation of microscopic hematuria were examined by phase-contrast microscopy to determine the probable site of bleeding into the urinary tract. Dysmorphic (i.e. morphologically variable) erythrocytes, suggestive of glomerular bleeding, were present in 86 of 87 patients with significant hematuria(More)
Multiple reports have outlined the potential benefits of the laparoscopic approach to colon surgery. Recently, randomized control trials have demonstrated the safety of applying these techniques to colorectal cancer. This study examined the long-term follow-up assessment of patients after laparoscopic colorectal cancer resections and compared them with a(More)
Perinuclear antineutrophil cytoplasmic antibodies (pANCAs) have previously been demonstrated in patients with various forms of vasculitis and more recently in those with inflammatory bowel disease (IBD) by an indirect immunofluorescence technique. Sera from 194 patients were tested for pANCAs: 101 with ulcerative colitis (43 with varying grades of disease(More)
Phase-contrast microscopy of the urine of a young Greek woman with macroscopic haematuria showed sickling of the red blood cells. The diagnosis of sickle-cell trait was confirmed with haemoglobin electrophoresis, and an intravenous pyelogram demonstrated the typical medullary cavities seen in this disease. Urine collected from the left ureter, from which(More)
