Serum lysozyme (muramidase) concentrations were measured in three groups of patients: control, ulcerative colitis and proctitis, and Crohn's disease. The mean +/-SD for each group was: control, 7 +/- 2; ulcerative colitis and proctitis, 7 +/- 2; and Crohn's disease, 10 +/- 4. Although a significant difference was seen between values in patients with Crohn's disease and values observed in those with ulcerative colitis or control patients, an important overlap was found between these groups. Further studies are necessary to explain the disparate results between this study and previous reports. 相似文献

ABSTRACT: BACKGROUND: Hepatocellular adenoma (HCA) in pregnant women requires special considerations because of the risk of hormone induced growth and spontaneous rupture, which may threaten the life of both mother and child. Due to scarcity of cases there is no evidence-based algorithm for the evaluation and management of HCA during pregnancy. Most experts advocate that women with HCA should not get pregnant or advise surgical resection before pregnancy. Whether it is justified to deny a young woman a pregnancy, as the biological behavior may be less threatening than presumed depends on the incidence of HCA growth and the subsequent clinical events during pregnancy. We aim to investigate the management and outcome of HCA during pregnancy and labor based on a prospectively acquired online database in the Netherlands. Methods/design The Pregnancy And Liver adenoma Management (PALM) - study is a multicentre prospective study in three cohorts of pregnant patients. In total 50 pregnant patients, [greater than or equal to] 18 years of age with a radiologically and/or histologically proven diagnosis of HCA will be included in the study. Radiological diagnosis of HCA will be based on contrast enhanced MRI. Lesions at inclusion must not exceed 5 cm. The study group will be compared to a healthy control group of 63 pregnant patients and a group of 63 pregnant patients with diabetes mellitus without HCA. During their pregnancy HCA patients will be closely monitored by means of repetitive ultrasound (US) at 14, 20, 26, 32 and 38 weeks of gestation and 6 and 12 weeks postpartum. Both control groups will undergo US of the liver at 14 weeks of gestation to exclude HCA lesions in the liver. All groups will be asked to fill out quality of life related questionnaires. DISCUSSION: The study will obtain information about the behaviour of HCA during pregnancy, the clinical consequences for mother and child and the impact of having a HCA during pregnancy on the health related quality of life of these young women. As a result of this study we will propose a decision-making model for the management of HCA during pregnancy. Trial registration Dutch trial register: NTR3034. 相似文献

Purpose: The use of topical fluoroquinolones to treat microbial keratitis is associated with an increased incidence of corneal perforation compared to other standard treatments. This study examined the effects of topical fluoroquinolones on corneal collagen and keratocytes in intact rabbit corneas and corneas with an epithelial defect. Methods: Studies consisted of one group of intact corneas and one group of corneas where a 6‐mm epithelial defect was created with a surgical scrape. Within each group, eyes were randomly assigned to one of four topical medications (0.3% ciprofloxacin, 0.3% ofloxacin, fortified antibiotics (1.36% tobramycin, 5% cefrazolin) or Tears Naturale (Alcon Laboratories, Frenchs Forest, NSW, Australia). Two drops were instilled hourly for 48 h and then 2‐hourly for an additional 48 h. At 96 h the corneas were removed and processed for light microscopy, immunohistology for collagen IV, V and VI, and apoptosis staining. Results: In intact rabbit corneas there was no demonstrable difference between treatment groups. In corneas with an epithelial defect, both fluoroquinolones delayed epithelial healing when compared to fortified antibiotics or tears. Keratocyte loss was seen in all groups and was greatest in the ofloxacin group. Median stromal thickness with keratocyte loss were: ofloxacin 30%; ciprofloxacin 10%; fortified antibiotics 7.5%; and tears 15% (ofloxacin vs tears, Mann?Whitney = 16.0, P = 0.09). Keratocyte loss did not correlate with the amount of demonstrable apoptosis. Collagens IV, V and VI showed no differences between treatments. Conclusions: These results suggest that ofloxacin is potentially cytotoxic to corneal keratocytes. Such an effect could lead to the observed increased incidence of corneal perforation in microbial keratitis. 相似文献

Evaluation of cosmetic outcome following breast‐conserving therapy in trials: panel versus digitalized analysis and the role of PROMs 下载免费PDF全文
Mirelle Lagendijk MD Elvira L. Vos MD Msc Daan Nieboer MSc PhD Cornelis Verhoef MD PhD Evelien M.L. Corten MD PhD Linetta B. Koppert MD MSc PhD 《The breast journal》2018,24(4):519-525
Cosmetic outcome is an important quality of life‐related end point following breast‐conserving therapy (BCT). To advise on a gold standard, we compare cosmetic outcome evaluated by panel and an objective evaluation (BCCT.core software). Second, patient‐reported outcome measures (PROMs) are compared to cosmetic outcome evaluation by panel and BCCT.core. Sixty‐eight breast cancer patients were included following BCT between 2007 and 2012. Two independent 6‐member panels and two observers using the BCCT.core evaluated cosmetic outcome. First, reproducibility, repeatability, and relatedness of panel and BCCT.core were analyzed using the interclass correlation coefficient (ICC). Second, the association between panel/BCCT.core with PROMs (EORTC‐QLQ‐C30/BR23, EQ‐5D‐5L, and BREAST‐Q) was analyzed with a linear regression and the goodness of fit by the R2. Both panel and BCCT.core evaluations showed “excellent” intraobserver agreement (ICC 0.93 [95% CI: 0.83; 0.97] and 0.93 [95% CI: 0.84; 0.97]) for respectively panel 1 and BCCT.core 1 and “excellent” interobserver agreement (ICC 0.94 [95% CI: 0.90; 0.96] and 0.85 [95% CI: 0.77; 0.91]) respectively for panel and BCCT.core. Association between panel and BCCT.core varied, ICC 0.59‐0.69. Only the PROM BREAST‐Q showed a significant association with both panel evaluations and BCCT.core observers (panel 1 and BCCT.core 1; R2 of .157 [P = .002] and .178 [P = .001]). Both panel and BCCT.core showed comparable “excellent” intraobserver and interobserver agreement. For future trials evaluating cosmetic outcome following BCT, one of those can be chosen. Solely, the PROM BREAST‐Q showed a significant association with panel and/or BCCT.core evaluation. To enable standardized cosmetic outcome evaluation and corresponding patient satisfaction in future trials, at least the BREAST‐Q should be combined with a panel or BCCT.core evaluation. 相似文献

This case study sought to delineate an overview of ethics training on Brazilian undergraduate dentistry courses, in order to gather knowledge related to the changes required with regard to training ethically competent health professionals. Thus, the scope of this study ethics training of students was defined by a conceptual reference, constructed at the interface of inter-related concepts. The reference also contributed to the outlining of this qualitative research, which includes a questionnaire with ethical-pedagogical questions, sent to the coordinators of 15 courses selected for the sample. The results indicated a timely commitment of the courses to the ethical dimension of professional training, as well as advances in training of teaching staff, the profile of the graduate and the curricular integration process. On the other hand, they highlighted deficiencies regarding the contents concerned with the cultural, humanistic and political background in relation to didactic orientation, the teaching-learning scenarios, the evaluation process, and also the incipient presence of bioethics regarding the subject and the crossover curricular theme, together with the lack of specific training of the teaching staff. 相似文献
