This study involved a randomized parallel groups comparison of the effects of aspirin formulated as enteric-coated granules (25 subjects) or as buffered tablets (26 subjects) with that of a lactose placebo (5 subjects), on the gastric and duodenal mucosa, as determined by endoscopic examination 2 h after a fasting single 975-mg dose. A grading scale of 0 (no damage) to 4 (severe damage) was used. The granule formulation produced a statistically significant (p less than 0.05) lower severity (mean 0.40 +/- 0.58 vs. 3.00 +/- 0.94) and incidence (36% of subjects vs. 100%) of gastric lesions than the buffered aspirin formulation. None of the lesions produced by the granule formulation or the placebo was considered clinically significant by the blinded endoscopist, whereas 17 subjects on the buffered formulation (65%) had clinically meaningful stomach damage. The incidence of duodenal lesions was minimal and comparable for the two formulations. 相似文献

Trisomy 22 mosaicism with normal blood chromosomes. Case report with literature review 总被引:1,自引:0,他引:1
A female infant with growth failure, microcephaly, hypertelorism, epicanthal folds, preauricular pit, congenital heart defect, hypotonia, and delayed development is reported. Trisomy 22 mosaicism (46,XX/47,XX,+22) was found in cultured skin fibroblasts but not in blood lymphocytes. Trisomy restricted to skin fibroblasts is uncommon. 相似文献

The authors present the first Brazilian series of laparoscopic cholecystectomy. Forty-one patients were operated on for gallstone disease between July and December 1990. Thirty-one operations were conducted by laparoscopy with no complications and good recovery of the patients. Two had to be submitted to laparotomy due to acute cholecystitis and a very difficult field for dissection. The authors concluded that the procedure is feasible, safe and has great advantages such as better cosmetic result, shorter hospital stay and home recovery time, lower postoperative pain and lower personal and social cost. 相似文献

PURPOSE: This study reports the results of a single-institution experience with high-dose-rate brachytherapy (HDRBT) used as a boost in the treatment of esophageal cancer with external beam radiation therapy (ERT) with or without chemotherapy. METHODS AND MATERIALS: Patients without evidence of metastatic disease were identified. HDRBT was given before ERT with a dose of 20 Gy in 5 fractions. Patients with a Karnofsky performance of more than 70 received treatment with 50 Gy in 25 fractions and concurrent 5-fluorouracil and cis-platinum during Weeks 1 and 5, whereas patients with a Karnofsky performance of less than 70 were treated with radiation therapy alone with 35 Gy in 14 fractions. RESULTS: Fifty-three patients received HDRBT treatment with combined ERT and chemotherapy and 17 patients with ERT alone. The incidence of acute bone marrow toxicity was 55% Grade 2 and 15% Grade 3, and 85% of patients had Grade 2 esophagitis. With a median follow-up time of 26 months, the median survival was 21 months; the 2-year local recurrence was 25%, and the 5-year survival rate was 28%. CONCLUSION: HDRBT is safe and beneficial for local control in the radical treatment of patients with esophageal cancer. 相似文献

A phenotypically normal male was found to have a chromosomal complement of 45,X/46,XY/47,XY, +21. This mosaic pattern has been reported only twice before. Although the patient had apparently fathered two children, he now has progressive impotence, absence of sperm in the seminal fluid, atrophic testes, almost complete absence of germ cells in testicular biopsies, high plasma LH and FSH, and a low normal testosterone. There were no physical characteristics of Turner's or Down's syndromes except for dermatoglyphic features commonly associated with the latter. These observations in this patients emphasise the value of chromosomal studies in multiple tissues in cases of mosaicism with atypical clinical features. 相似文献

Psychological distress, social support, and disease activity in patients with inflammatory bowel disease 总被引:5,自引:0,他引:5

OBJECTIVES: The objectives of this study were to compare the psychological status of patients in active and inactive disease states, to assess social support, and to identify correlates of psychological distress in patients with inflammatory bowel disease (IBD). METHODS: This cross-sectional study was conducted in 200 patients (mean age 36.7 yr [SD = 14.8], 119 [59.5%] female) with long-standing IBD who were seen in tertiary care. Psychosocial assessments included psychological distress (Symptom Checklist-90R), social support (Social Support Questionnaire-6), perceived stress (Perceived Stress Scale-10), and recent minor stressful events (Weekly Stress Inventory). Disease activity was assessed with the Harvey Bradshaw Index. RESULTS: Patients reported higher levels of satisfaction with social support and smaller network sizes compared with normative values. Using multiple linear regression, the independent correlates of psychological distress (p = 0.0001; adjusted R2 = 0.62) were as follows: active disease (p = 0.0234), less time since diagnosis (p = 0.0012), and greater number (p = 0.0001) and impact of stressful events (p = 0.0003). A statistically significant interaction term (p = 0.0171) revealed that the relationship between psychological distress and perceived stress changes depending on the level of satisfaction with social support. For patients with low levels of perceived stress, satisfaction with social support did not affect levels of psychological distress. However, for patients who experienced moderate to high levels of perceived stress, high satisfaction with social support decreased the level of psychological distress. CONCLUSIONS: These findings suggest that strategies aimed at improving social support can have a favorable impact on psychological distress and, ultimately, can improve health outcomes in patients with IBD. 相似文献

Psychosocial correlates of patient-physician discordance in inflammatory bowel disease 总被引:2,自引:0,他引:2

OBJECTIVE: The aim of this study was to identify the independent psychosocial correlates of patient-physician discordance in adult outpatients with inflammatory bowel disease. METHODS: This cross-sectional study was conducted in three university-affiliated tertiary care settings. Psychological distress, social support, perceived stress, and negative life events were assessed, as were demographic, lifestyle, and clinical characteristics. Patient-physician discordance was assessed with 10-item questionnaires. RESULTS: Ten gastroenterologists and 200 of their patients participated. Patients and their physicians disagreed most on discussion of personal issues. Patients with Crohn's disease had statistically significantly higher discordance on disease activity and physical limitation, as well as higher average overall discordance scores than patients with ulcerative colitis. Mean discordance levels were similar across different physicians. Higher psychological distress and more perceived stress were independently associated with higher discordance after controlling for Crohn's disease, active disease, being with the treating physician for less than 1 yr, and recommendation for further medical investigation. Psychological distress was the most important correlate of overall discordance. CONCLUSIONS: Increased physician awareness that psychologically distressed patients have difficulty processing of clinically relevant information may lead to improved doctor-patient communication during an office visit. 相似文献
