摘要:
Attributable risk models describe the role of three risk factors for peptic ulcer and related serious upper gastrointestinal (GI) events. The factors-nonsteroidal antiinflammatory drugs (NSAIDs),Helicobacter pylori,and cigarette smoking-have been identified as major risk factors for peptic ulcer in numerous clinical and epidemiologic studies. Overall risk ratios for each risk factor were based on meta-analyses of English-language studies of risk for peptic ulcer-related GI events. Exposure estimates for factors used data from North American populations. Summary risk and exposure values were computed for the general population, males and females separately, and the elderly. Hypothetical models of multiple factor attributable risks were developed using population attributable risk percents calculated from these summary values. General population attributable risk percents were as follows: 24%, NSAIDs; 48%,H. pylori;and 23%, cigarette smoking. Based on these numbers, the "no interaction" attributable risk model estimates that 95% of total peptic ulcer related risk is attributable to these factors in the general population. The "interaction" model attributes 89% of cases to these risk factors: 24%, NSAIDs alone; 31%,H. pylorialone; 34%,H. pylori/smoking combined. Between 89% and 95% of peptic ulcer-related serious upper GI events may be attributed to NSAID use,H. pyloriinfection, and cigarette smoking.

摘要:
Five patients with Whipple's disease all suffered from arthralgia for a long time (15 years in one case) before developing gastrointestinal or other symptoms. In all patients, arthralgia was seronegative, and there was no evidence of joint destruction. Arthralgias were symmetric and migrating. Whipple's disease is part of the differential diagnosis of enteropathic arthralgia. Thereby, the polymerase chain reaction can be a helpful tool to prove Whipple's disease in difficult differential diagnosis.

摘要:
Zollinger-Ellison syndrome (ZES) and acromegaly are two hypersecretory states in which colorectal neoplasia has been described, but the incidence in the former condition may not be increased. We describe four patients with colorectal neoplasia associated with the ZES and review other published cases. Tissue ELISA with Adnab-9 antibody, a putative colorectal cancer risk marker, from a patient with ZES and from seven patients with acromegaly was compared to 13 controls at average risk for colorectal neoplasia. The patient with ZES without detectable colonic neoplasia and seven patients with acromegaly had increased binding of Adnab-9 in the colonic mucosa by ELISA. The difference was significant for the acromegaly patients compared to the controls (p < 0.05). The accumulated 34 instances of colorectal neoplasia in ZES patients suggests that this association may not be rare. Adnab-9 expression, detectable in both ZES and acromegaly, may reflect predisposition to colorectal neoplasia in both hypersecretory states. Therefore, while a basis for association of colorectal neoplasia and hypergastrinemia exists, the clinical data are not compelling enough to warrant surveillance of patients with ZES. To resolve this problem, more definitive case control studies should be conducted.

摘要:
Though pathogenetically qualifying as an enteric fever, the gastroenterological manifestations of Brucella in humans are relatively uncommon. We present a typical case of Brucellosis with gastrointestinal symptoms and review these by organ involvement, ranging from the mild nonspecific, such as diarrhea and abdominal pain, to the pathologically distinct hepatic lesions, and to the rare colonic, pancreatic, and peritoneal involvement. The limited indications for diagnostic procedures, such as endoscopy and liver biopsy are discussed.

摘要:
In Israel, the reported prevalence of hepatitis-C virus (HCV) infection among blood donors is 0.44%. As we found a high prevalence of chronic hepatitis-B virus (HBV) and HCV infection in Jewish immigrants from Uzbekistan and Tajikistan (Bukharian Jews) among our general patient population, we determined the prevalence of HBV and HCV infection among "healthy" Bukharian Jewish immigrants by screening for HBV and HCV markers and risk factors in a population of Bukharian Jews in north Jerusalem. A total of 27 (26.5%) of 102 patients were anti-HCV positive (by ELISA and confirmation tests). The HCV positive patients were older and had a higher rate of liver enzyme abnormalities than were the HCV-negative patients (56.5 ± 2.3 versus 47.6 ± 1.8, p = 0.003; and 14 of 27 versus 7 of 75, p < 0.01, respectively). HCV-positive patients with liver enzyme abnormalities were younger than HCV-positive patients without liver enzyme abnormalities (52.5 ± 3.0 versus 62.8 ± 2.8, p = 0.02). Sixteen patients (15.7%) were hepatitis-B surface antigen (HBsAg) carriers, and only two of these HBsAg carriers had liver enzyme abnormalities. None of the HCV-positive patients were HBsAg carriers (0 of 27 among HCV-positive patients versus 16 of 75 among HCV-negative patients, p = 0.0055). Past infection with HBV was found in 67 examinees (66%) (45 of 75 HCV-negative patients and 22 of 27 HCV-positive patients, p = 0.058). However, similar proportions of patients from both groups had past and present exposure to HBV [61 (81.3%) of 75 among HCV-negative patients versus 22 (81.5%) of 27 among HCV-positive patients]. Only 14 patients (13.7%) had no exposure to either HCV or HBV. Possible risk factors were use of nondisposable needles during mass vaccination in the U.S.S.R. or possible intrafamilial spread. The study concluded that immigrant Jews from former Asiatic U.S.S.R. republics have the highest rate of HCV positivity ever reported, and many of them have past and present HBV infection. Measures to prevent intrafamilial transmission of both viruses should be instituted.

摘要:
A 49-year-old man with Crohn's disease treated with prednisone and mesalamine (5-ASA) developed worsening respiratory distress and fever. Symptoms improved after discontinuation of mesalamine. A rechallenge 3 months later caused similar pulmonary symptoms, confirming the association between the drug and the respiratory system. Mesalamine may cause hypersensitivity pneumonitis in patients with Crohn's disease.

摘要:
A patient with nephrotic syndrome had been treated with mesalazine for ulcerative colitis, and also had a carcinoma of the colon and sclerosing cholangitis. This seemingly unrelated series of complications gives us the opportunity to review the problem of nephropathy in ulcerative colitis.

摘要:
A 54-year-old man with chronic hepatitis C virus (HCV) developed quadrihemianopsia caused by lacunar brain infarction. Extensive evaluation revealed high titers of anticardiolipin antibodies (ACA). Following interferon treatment (6 × 106, three times a week for 2 months and 3 × 106for another 7 months), liver transaminase levels decreased to normal, HCV RNA in blood was no longer detectable, concomitantly with the disappearance of the ACA. The patient remained clinically stable without evidence for either HCV activity (RNA) or ACA or further thromboembolic events.

摘要:
We studied the seroprevalence of human immunodeficiency virus infection in patients with pulmonary tuberculosis and abdominal tuberculosis. We also assessed the clinical characteristics, risk factors, tuberculin status, site, and response to therapy of abdominal tuberculosis in human immunodeficiency virus (HIV)-seropositive and HIV-seronegative patients. Volunteer blood donors (n = 8,395), patients with pulmonary tuberculosis (n = 387), and patients with abdominal tuberculosis (n = 108) were screened for HIV 1 and/or HIV 2 by enzyme-linked immunosorbent assay (ELISA; Torrent, India) and positivity reconfirmed by a repeat ELISA and Western blot test. The HIV seroprevalence in the abdominal tuberculosis patients (16.6%) was significantly higher compared with those with pulmonary tuberculosis (6.9%, p < 0.05) and volunteer blood donors (1.4%, p < 0.01). Absolute lymphocyte counts did not differ between the HIV-seropositive and HIV-seronegative patients (2,044.94 ± 830 vs 2,261.34 ± 805/mm3, p = NS). The Mantoux reaction was larger in the HIV-seronegative group as compared with the HIV-seropositive group (14.8 mm vs. 9.5 mm, p < 0.05). Tuberculosis patients responded well to conventional antituberculosis drugs in standard doses regardless of their HIV status.
