13. Proctitis in homosexual men. A diagnostic problem.
One hundred and seventy six men with histories of anal intercourse were studied to determine if there was a correlation between the clinical features, cytological findings in the mucosal secretions, and the histological appearance of the rectal mucosa. The presence or absence of gastrointestinal symptoms did not differentiate between patients with and withou

15. Structure and significance of metaplastic nodules in the rectal mucosa
Small nodules are commonly seen in the rectal mucosa during sigmoidoscopy of patients over 40 years of age and are often noted in rectums excised for carcinoma.

16. Campylobacter-like organisms are uncommon pathogens in patients infected with the human immunodeficiency virus.
Over a 25-month period, we prospectively evaluated 36 patients with symptomatic human immunodeficiency virus disease (including 27 with unexplained chronic diarrhea) by flexible sigmoidoscopy for the presence of Campylobacter-like organisms. No Campylobacter-like organisms were isolated. Campylobacter-like organisms appear to be an uncommon cause of idiopath

17. Prevalence of occult inflammatory bowel disease in ankylosing spondylitis.
Fifty-five patients with ankylosing spondylitis and 16 control patients matched for sex and age were examined for evidence of occult inflammatory bowel disease. In all patients evaluation included history and physical examination, barium enema, sigmoidoscopy, and rectal biopsy. The results of this study suggest that there is no increased prevalence of occult

18. Chemical and immunological testing for faecal occult blood in screening subjects at risk of familial colorectal cancer.
BACKGROUND: People with a family history of colorectal cancer have an increased risk of the disease themselves. Many centres are advocating family history screening by endoscopy. AIMS: The performance of chemical and immunological faecal occult blood tests (Haemoccult and Hemeselect) in 212 subjects with a family history of colorectal cancer was assessed. RE

19. Preoperative radiation and chemotherapy in the treatment of adenocarcinoma of the rectum.
OBJECTIVE: In this study, the impact of preoperative chemotherapy and radiation on the histopathology of a subgroup of patients with rectal adenocarcinoma was examined. As well, survival, disease-free survival and pelvic recurrence rates were examined, and compared with a concurrent control group. SUMMARY BACKGROUND DATA: The optimal treatment of large recta

20. Two cases of 5q deletions in patients with familial adenomatous polyposis: possible link with Caroli's disease.
Two cases are reported of patients with deletions of chromosome 5q. Both have familial adenomatous polyposis (FAP) and mild mental retardation. In both, macroscopic polyposis was confined to the proximal colon in adult life (in their thirties) although microscopic adenomatosis was shown in the more distal colon with occasional single polyps. Both subjects ha

21. Screening for cancer.
Screening has proved effective for only two cancer sites, the breast and the cervix uteri. Only for these, therefore, should screening be a part of routine clinical practice. The degree to which screening is effective depends on whether appropriate groups are screened. For cancer of the breast, current evidence justifies mammographic screening every two year

22. Safety and efficacy of high-dose treatment with imipenem-cilastatin in seriously ill patients.
Imipenem-cilastatin was given in doses of 1 g intravenously every 6 h to 31 patients. Twenty-five patients, with 27 infections, were clinically evaluable and received 20 to 210 g of imipenem for a duration of 5 to 56 days (average 16.3 days). Infections included seven cases of osteomyelitis, seven of bacteremia, five of cellulitis, two of pneumonia, three of

23. Results of a pilot study of endoscopic screening of first degree relatives of colorectal cancer patients in Italy.
STUDY OBJECTIVE: Screening recommendations for colorectal cancer include sigmoidoscopy in asymptomatic, average risk persons aged 50 and over and colonoscopy every three to five years in high risk groups. Little is known about the eligible population's compliance with endoscopic screening. This is the first Italian report of an endoscopic screening programme

24. The utility of computed tomography in colonic diverticulitis.
Forty-one patients admitted to our hospital during an 18-month period with the clinical diagnosis of colonic diverticulitis were analyzed to evaluate the utility of computed tomography (CT). Abdominal pain and leukocytosis were the most common presenting manifestations, 75 and 66%, respectively. Just over one-half of the patients also demonstrated hematuria.
