The regimen of Group C is significantly better than the regimens of Groups A or B in bowel cleansing. Regimens of Groups A and B did not differ in efficacy of cleansing. It is the timing of taking NaPh in the regimen of Group C rather than its composition that is responsible for its superior cleansing ability compared with PEG. Overnight deposition of small intestinal material in the right colon is partly responsible for the inferior cleansing ability of regimens that involve taking the solution on the day before colonoscopy. Despite a higher incidence of minor side-effects from NaPh than from PEG, a significantly higher proportion of patients preferred NaPh.
We have previously published two reports on acute infection with Helicobacter pylori, one of an adult male and one of a family of four. In the present study, we have isolated H. pylori from each of twin boys in the family and compared these by use of random amplified polymorphic DNA PCR. In addition, we have monitored the antibody response over time of the family and the adult male by Western blotting (immunoblotting) with two different strains of H. pylori as the antigen and by use of a commercial kit. The acutely infected twin boys were infected by an identical strain of H. pylori. The twin boys responded to antigens of 19, 26.5, and 29 kDa 30 days after the initial diagnosis, with recognition of 43-to 49-, 66-, 69-, and 87-kDa antigens by day 63. One twin responded to the CagA antigen on day 63, whereas the other responded on day 857. Antibody to the CagA antigen was not detected by use of the infecting strain, UNSW-RU1. Investigation of UNSW-RU1 revealed the presence of cagA. In two acutely infected adults (one, the father of the boys), the initial response to a 45-kDa antigen was later followed by responses to 19-, 29-, 49-, 60-, 77-, and 84-kDa antigens. Sera from the twins' younger sister, born 17 months after the twins acute episode, indicated that she also had become infected. This report supports intrafamilial transmission of H. pylori. Initial antibody responses in the children were to small-molecular-size antigens; in the adults, the initial responses were to larger-molecular-size antigens. The pattern of the serological response differs according to the antigen used. This has implications in regard to international data comparisons.
Oesophageal H. pylori infection is uncommon in patients with Barrett's IM, dysplasia, or adenocarcinoma, and may be restricted to non-intestinalized columnar epithelium. Gastric H. pylori infection may have a protective effect for the development of Barrett's oesophagus.
Urinary copper excretion was found to be increased in patients with cholestasis, hepatitis and cirrhosis, but the penicillamine-induced increment was normal. Wilson’s disease patients had increased copper excretion before and after penicillamine, especially in untreated cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
