    A 10-year experience in the diagnosis and treatment of 92 patients with inflammatory bowel diseases in Kuala Lumpur is described. Tuberculosis (34 cases) was the most common inflammatory bowel disease of surgical importance. The clinical presentation of tuberculous enteritis and Crohn's disease is similar, though tuberculosis is strongly suggested by associated pulmonary disease and radiological evidence of caecal involvement. The finding of 10 cases each of Crohn's disease and ulcerative colitis is in keeping with an increased awareness of these conditions in a developing urban society where facilities exist for thorough investigation of diarrhoeal diseases. Amoebiasis sometimes causes a granulomatous lesion simulating carcinoma. Diverticular disease of the colon as known in the West is of very rare occurrence.

    Entamoeba histolytica infection remains a public health concern in developing countries. Early diagnosis of amoebiasis can avoid disease complications, thus this study was aimed at developing a test that can rapidly detect the parasite antigens in stool samples. Rabbits were individually immunized with recombinant pyruvate phosphate dikinase (rPPDK) and E. histolytica excretory-secretory antigens to produce polyclonal antibodies. A rapid dipstick test was produced using anti-rPPDK PAb lined on the dipstick as capture reagent and anti-EhESA PAb conjugated to colloidal gold as the detector reagent. Using E. histolytica-spiked in stool sample of a healthy individual, the detection limit of the dipstick test was found to be 1000 cells ml-1. Meanwhile when rPPDK was spiked in the stool sample, the minimum concentration detected by the dipstick test was 0.1 μg ml-1. The performances of the dipstick, commercial Techlab E. histolytica II enzyme-linked immunosorbent assays (ELISA) and real-time PCR were compared using 70 stool samples from patients infected with Entamoeba species (n = 45) and other intestinal pathogens (n = 25). When compared to real-time PCR, the diagnostic sensitivity of the dipstick for detection of E. histolytica was 65.4% (n = 17/26); while the diagnostic specificity when tested with stool samples containing other intestinal pathogens was 92% (23/25). In contrast, Techlab E. histolytica II ELISA detected 19.2% (5/26) of the E. histolytica-positive samples as compared to real-time PCR. The lateral flow dipstick test produced in this study enabled rapid detection of E. histolytica, thus it showed good potential to be further developed into a diagnostic tool for intestinal amoebiasis.
