Sonographic patterns of Caroli's disease: report of 5 new cases. 总被引:1,自引:0,他引:1
We have reviewed 5 cases of Caroli's disease, studied from 1982 to 1987, in order to define the validity of its sonographic signs. The "intraluminal portal vein" sign, found in all the cases, is emphasized. This sign may be easily identified and it is never encountered in other diseases. Recessive polycystic kidney disease was present in 3 cases, and congenital hepatic fibrosis was demonstrated in the 2 cases studied by liver biopsy. 相似文献

BACKGROUND: Magnetic resonance imaging studies in schizophrenia have revealed abnormalities in temporal lobe structures, including the superior temporal gyrus. More specifically, abnormalities have been reported in the posterior superior temporal gyrus, which includes the Heschl gyrus and planum temporale, the latter being an important substrate for language. However, the specificity of the Heschl gyrus and planum temporale structural abnormalities to schizophrenia vs affective psychosis, and the possible confounding roles of chronic morbidity and neuroleptic treatment, remain unclear. METHODS: Magnetic resonance images were acquired using a 1.5-T magnet from 20 first-episode (at first hospitalization) patients with schizophrenia (mean age, 27.3 years), 24 first-episode patients with manic psychosis (mean age, 23.6 years), and 22 controls (mean age, 24.5 years). There was no significant difference in age for the 3 groups. All brain images were uniformly aligned and then reformatted and resampled to yield isotropic voxels. RESULTS: Gray matter volume of the left planum temporale differed among the 3 groups. The patients with schizophrenia had significantly smaller left planum temporale volume than controls (20.0%) and patients with mania (20.0%). Heschl gyrus gray matter volume (left and right) was also reduced in patients with schizophrenia compared with controls (13.1%) and patients with bipolar mania (16.8%). CONCLUSIONS: Compared with controls and patients with bipolar manic psychosis, patients with first-episode schizophrenia showed left planum temporale gray matter volume reduction and bilateral Heschl gyrus gray matter volume reduction. These findings are similar to those reported in patients with chronic schizophrenia and suggest that such abnormalities are present at first episode and are specific to schizophrenia. 相似文献

OBJECTIVE: Patients affected by schizophrenia show deficits in both visual perception and working memory. The authors tested early-stage vision and working memory in subjects with schizotypal personality disorder, which has been biologically associated with schizophrenia. METHOD: Eleven subjects who met DSM-III-R criteria for schizotypal personality disorder and 12 normal comparison subjects were evaluated. Performance thresholds were obtained for tests of visual discrimination and working memory. Both form and trajectory processing were evaluated for each task. RESULTS: Subjects with schizotypal personality disorder showed intact discrimination of form and trajectory but were impaired on working memory tasks. CONCLUSIONS: These data suggest that subjects with schizotypal personality disorder, unlike patients affected by schizophrenia, have relatively intact visual perception. Subjects with schizotypal personality disorder do show specific deficits on tasks of comparable difficulty when working memory demands are imposed. Schizotypal personality disorder may be associated with a more specific visual processing deficit than schizophrenia, possibly reflecting disruption of frontal lobe systems subserving visual working memory operations. 相似文献

PURPOSE: Gemcitabine remains the standard therapy for metastatic pancreatic adenocarcinoma (ACA), but has limited activity. ISIS-2503 is an antisense compound directed against H-ras with preclinical activity against pancreatic ACA in tumor models. The combination of ISIS-2503 and gemcitabine has been evaluated in a prior phase I study. METHODS: Patients with metastatic or locally advanced pancreatic ACA not amenable to surgery or local radiation received gemcitabine 1,000 mg/m(2) intravenously over 30 minutes on days 1 and 8 and ISIS-2503 6 mg/kg/d as a continuous intravenous infusion over 14 days of an every-3-weeks cycle. Responses were monitored by radiologic imaging every 6 weeks. RESULTS: Forty-eight eligible patients were enrolled, 43 with metastatic disease. Median follow-up was 12.6 months (range, 2.2 to 16.8 months) for living patients. A median of four cycles of treatment was given (range, 1 to 18 cycles). All patients were assessable for response and toxicity. The 6-month survival percentage was 57.5% (95% CI, 44.9% to 73.5%) and the median survival was 6.6 months. The response rate was 10.4% (one complete response, four partial responses). Clinically significant toxicity was limited except for one fatal pulmonary embolism. CONCLUSION: This study shows a promising response rate to the combination of gemcitabine and ISIS-2503 in patients with pancreatic ACA. The observed 6-month survival rate in these patients met our protocol-defined criteria for success. This regimen is tolerable, but is of unclear benefit. Additional studies evaluating the role of gemcitabine and ISIS-2503 in the treatment of pancreatic ACA should be considered. 相似文献

PURPOSE: Women with breast cancer were provided with an audiotape of their primary adjuvant treatment consultation, and the following patient outcomes were measured at 12 weeks postconsultation: perceived degree of information provision, audiotape satisfaction and use, communication satisfaction with oncologist, mood state, and cancer-specific quality of life. PATIENTS AND METHODS: Participants included 628 women newly diagnosed with breast cancer and 40 oncologists from six cancer centers in Canada. The patients were block randomized to one of four consultation groups: standard care control, not audiotaped; audiotaped, no audiotape given; audiotaped, patient given audiotape; and audiotaped, patient offered choice of receiving audiotape or not. RESULTS: Patients receiving the consultation audiotape had significantly better recall of having discussed side effects of treatment than patients who did not receive the audiotape. Audiotape benefit was not significantly related to patient satisfaction with communication, mood state, or quality of life at 12 weeks postconsultation, and was not significantly affected by choice of receiving the audiotape. Patients rated the audiotape intervention positively, with an average score of 83.9 of 100. CONCLUSION: Audiotape provision benefits patients by facilitating their perception of being informed about treatment side effects, but does not significantly influence patient satisfaction with communication, mood state, or quality of life. 相似文献

Randomised controlled trial of advice on an egg exclusion diet in young children with atopic eczema and sensitivity to eggs 总被引:2,自引:0,他引:2

Background: The role of exclusion diets in the management of atopic eczema in young children is uncertain. This randomised controlled trial evaluates the effect of excluding egg from the diet in young children with atopic eczema and sensitivity to eggs. Fifty-five such children were randomised either to a 4-week regimen, in which mothers were given general advice on care of eczema and additional specific advice from a dietician about an egg exclusion diet (diet group), or to a control group in which general advice only was given. Both groups continued conventional topical treatment. Disease activity was assessed by estimates of the surface area affected by eczema and by an arbitrary severity score. Possible egg sensitivity was identified by RAST before randomisation and after the trial by double-blind placebo-controlled egg challenge. Results: The mean reduction in surface area affected by eczema was significantly greater (p = 0.02) in the group receiving dietary advice (from 19.6% to 10.9% area affected) than in the control group (from 21.9% to 18.9%). A significant improvement also occurred in severity score (p=0.04): from 33.9 to 24.0 units for the diet group compared with a decrease from 36.7 to 33.5 in the control group. The study suggests that advice on the dietary exclusion of eggs is useful as part of the overall management of young children with atopic eczema and sensitivity to eggs. 相似文献

Objectives: Evaluate the age-dependency of ciliary beat frequency (CBF) in biopsies after ciliogenesis in culture. Study Design: Retrospective analysis of CBF and ciliary ultrastructure in biopsies and after ciliogenesis from 203 individuals, aged 3 months to 74 years. Methods: All patients with successful culture were included. Ciliogenesis was obtained using the sequential monolayer-suspension culture technique for dissociated nasal epithelial cells. CBF was measured using computerized microscope photometry. Secondary ultrastructural abnormalities were evaluated in transmission electron microscopy. Results: There was no correlation between age and CBF, in either the biopsies (7.0 ± 2.6 Hz; n = 113) or after ciliogenesis in culture (8.1 ± 1.3 Hz; n = 203). Even in individuals older than 70 years, CBF was normal in bioptic material (6.7 ± 1.7 Hz) and after ciliogenesis in culture (7.9 ± 1.0 Hz). Also, in individuals less than 1 year of age CBF was normal in biopsies as well as after ciliogenesis. CBF correlated inversely with the percentage of secondary ultrastructural abnormalities in the biopsies as seen with transmission electron microscopy: 8.1 ± 1.8 Hz when ciliary ultrastructure was normal and 3.5 ± 3.3 Hz in cases of severe secondary ciliary dyskinesia. After ciliogenesis in culture, ciliary ultra-structure was always normal, as was CBF. Conclusion: CBF is age independent but correlates with secondary ultrastructural abnormalities. CBF after ciliogenesis in culture is the intrinsic one. 相似文献

Reducing risk factors for patients with vascular disease can reduce the subsequent incidence of cerebro-cardiovascular disease. While physicians have had extensive training in the importance of atherosclerotic vascular disease risk factor modification, evidence suggests that they systematically miss opportunities for clinical prevention during routine practice. The aim of this study was to identify whether physicians felt confident in their knowledge and effectiveness regarding counseling patients to reduce cardiovascular risk and to determine barriers to prevention interventions in the office setting. Surveys were mailed to 509 physicians affiliated with an academic community hospital. Nonrespondents were sent reminders and a second survey. Comparisons were made using chi-square analysis. Two hundred and five surveys were returned (40.3%). Thirty-six percent of physicians felt knowledgeable about weight management techniques, compared to 3% who were confident that they succeeded in their practice (p < 0.001). Similar patterns were found for Tobacco Cessation (62% versus 14%, p = 0.001), Alcohol Reduction (46% versus 7%, p < 0.001), Stress Management (35% versus 5%, p < 0.001), Exercise (53% versus 10%, p < 0.001), Nutrition (36% versus 8%, p < 0.001), Diabetes Management (48% versus 23%, p < 0.001), Blood Pressure Management (57% versus 43%, p < 0.001) and Lipid Management (59% versus 38%, p < 0.001). We identified a significant gap between physician confidence in their knowledge about risk factors and their effectiveness at providing counseling and obtaining results in their office. Most physicians felt that the routine office follow-up visit was an ineffective method for instituting vascular risk factor reduction. Alternate settings for risk factor reduction may be needed for improving atherosclerosis prevention. 相似文献

This purpose of this study was to investigate the relationship between quality of life and psychiatric impairment in a Taiwanese community located near the epicenter of the 1999 earthquake, as assessed four to six months after the natural catastrophe. Trained assistants interviewed the 4223 respondents using the disaster-related psychological screening test (DRPST), an instrument specifically designed and validated by senior psychiatrists for assessment of psychiatric impairment after natural catastrophe. Additionally, the 36-Item Short-Form Health Survey (SF-36) was used to evaluate quality of life. The collected results were analyzed using Windows SPSS 10.0 software. Psychiatric impairment rated moderate to severe was assessed for 1448 (34.3%) of the responding residents. The 4223 respondents were divided into 4 psychiatric-impairment groups based on DPRST score: healthy (n = 952); mild impairment (n = 1823); moderate impairment (n = 1126); and, severe impairment (n = 322). The four groups were compared for a number of salient factors, including gender, age, current marital status and psychiatric-impairment score, to determine impact on quality of life. Respondents assessed as psychiatrically impaired tended to be older, female, divorced/widowed, and less educated, and they were more likely to have experienced major familial financial loss as an immediate consequence of the earthquake. Further, the greater the severity of the psychiatric impairment, the lower the scores for quality of life, for both the physical and mental aspects of this important general indicator. 相似文献

The impact of goal attainment in a dietary change program to increase fruit, 100% juice, and vegetable consumption was assessed among fourth-grade students. At each session, the students were given goals related to increasing fruit, juice, and vegetable consumption. Baseline consumption and postconsumption were assessed with up to 4 days of computerized dietary recalls. Analyses included regression models predicting postconsumption from the numbers of fruit-juice goals, vegetable goals, or total number of general goals attained, respectively. For students with low baseline fruit-juice preferences, attaining more fruit-juice goals resulted in increased post-fruit-juice consumption. Among those with low baseline vegetable consumption, attaining one vegetable goal was related to higher post-vegetable consumption. For boys and those with high baseline fruit, juice, and vegetable consumption, attaining three general goals was related to increased fruit, juice, and vegetable intake. The results show that goal attainment was somewhat effective in promoting dietary change among children. 相似文献
