13. Medical audit of rectal biopsy diagnosis of inflammatory bowel disease.
The records of the rectal biopsy diagnoses of ulcerative colitis and Crohn's disease in the Department of Pathology, St Mark's Hospital, London, were reviewed. The biopsy diagnoses were compared to subsequent resection diagnoses on the same patients, and annual and seasonal variations in the frequency of these and related diagnoses were studied. The accuracy

14. Value of counting colonic mucosal Ig-containing cells in the differential diagnosis of chronic inflammatory bowel disease.
AIMS: To investigate whether counting cells containing immunoglobulin (Ig) subclass in colonic biopsy specimens of patients with chronic inflammatory bowel disease, in addition to conventional histological evaluation, can improve the differentiation of patients with Crohn's disease from those with ulcerative colitis. METHODS: The colonic and rectal biopsy sp

15. Observer variability in the histopathological reporting of abnormal rectal biopsy specimens.
AIMS--To study the consistency of reporting of abnormal rectal biopsy specimens, especially in the differentiation of inflammatory bowel disease from other causes of abnormality. METHODS--Sixty rectal biopsy specimens were identified from patients presenting with bloody diarrhoea. These were then circulated to the 11 consultant pathologists in the study who

16. Audit of the histopathological diagnosis of non-neoplastic colorectal biopsies: achievable standards for the diagnosis of inflammatory bowel disease.
AIM: To assess the performance of a histopathology department in diagnosing inflammatory bowel diseases with comparison of reports from other centres. STUDY POPULATION: 1067 sets of endoscopic biopsies received in the department of histopathology, Royal Hallamshire Hospital, 1990-1995. METHODS: The histopathological diagnosis of non-neoplastic endoscopic col

17. A quantitative study of immunoglobulin containing cells in the differential diagnosis of acute colitis.
In colonic biopsies of 33 patients with acute colitis caused by campylobacter, salmonella, or shigella immunoglobulin containing cells were determined quantitatively using an indirect immunoperoxidase technique and morphometry with a graphic tablet. The findings were compared with those of 10 patients without histological abnormalities, 10 patients with Croh

18. Value of mucin histochemistry in follow up surveillance of patients with long standing ulcerative colitis.
It has been suggested that diffuse changes in epithelial mucins may help to identify a subgroup of patients with ulcerative colitis who are at increased risk of developing colorectal cancer. Colonoscopic biopsy specimens were taken from 11 colitic patients shortly before colectomies were performed, in which cancer was identified. These patients were matched

19. Histological features of sclerosing cholangitis in patients with chronic ulcerative colitis.
Primary sclerosing cholangitis was diagnosed radiologically in 16 of 681 patients (2.2%) with chronic ulcerative colitis in a follow up study at the gastroenterology unit in Oxford. On the basis of established histological criteria, the liver biopsy was considered diagnostic in only half of the cases. The histological findings in these cases were therefore r

20. Axonal necrosis of enteric autonomic nerves in continent ileal pouches. Possible implications for pathogenesis of Crohn's disease.
OBJECTIVE: Axonal necrosis was first described in samples of small intestine from patients with Crohn's disease (A.M. Dvorak et al. Hum Pathol 1980; 11:620-634). Clinically evident inflammation of continent ileal reservoirs (pouches) has clinical features that resemble Crohn's disease. Possible similarities in the pathogenesis of Crohn's disease and pouchiti

21. Ileal pouch-anal anastomoses complications and function in 1005 patients.
BACKGROUND: Restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA) has become an established surgery for patients with chronic ulcerative colitis and familial adenomatous polyposis. PURPOSE: The authors report the results of an 11-year experience of restorative proctocolectomy and IPAA at a tertiary referral center. METHODS: Chart review was per

22. Ileal pouch-anal anastomosis. A single surgeon's experience with 100 consecutive cases.
Between August 1982 and November 1985, 100 patients underwent ileal "J" pouch-anal anastomosis (IPAA) at the University of Utah. All operations were performed in a standard fashion by a single surgeon. Seventy-eight patients were operated on for chronic ulcerative colitis and 22 for familial polyposis coli. Sixty of the patients were male and 40 were female

23. A comparison of multiple synchronous colorectal cancer in ulcerative colitis, familial polyposis coli, and de novo cancer.
Multiple synchronous colorectal cancer (MSCC) among 1537 patients (69 with familial polyposis coli (FPC), 780 with ulcerative colitis (UC), and 685 with de novo colorectal (DNC) cancers) admitted to The Mount Sinai Hospital between 1945 and 1981 was tabulated. MSCC occurred in five of 24 cancer patients with FPC (21%), in 12 of 65 cancer patients with UC (18

24. Circulating antibodies to Saccharomyces cerevisiae (bakers'/brewers' yeast) in gastrointestinal disease.
AIM: To measure circulating antibodies to yeast organisms that could be used to characterise the yeast specific immune response in gastrointestinal disease. METHODS: A quantitative, isotype specific enzyme linked immunosorbent assay was developed to measure circulating antibodies to an aqueous extract of Saccharomyces cerevisiae (sacc). Comparisons of specif
