Rats were given enemas of Gastrografin in two strengths, Renografin--76, and Tween--80 in a 10% dilution. There were no deleterious effects on the colons with these media used in volumes to fill the colon. Severe changes resulted from volumes which produced overdistention. 相似文献

Between 1983 and 1985, 595 employees who were entering retirement in East Germany were given a medical examination and asked to assess their workplace conditions. Ten years later, we examined whether occupational predictors were associated with death and functional dependence among the study participants and assessed how the surviving pensioners coped with activities and instrumental activities of daily living. We assigned the occupational factors reported between 1983 and 1985 to two scales: demands and resources. Multiple logistic regression analyses were carried out to examine the association of occupational and medical predictors with the outcome variables death and functional dependence. Workplace resources but not demands were significantly associated with a reduced chance of death in women, independent of medical diagnoses. For men neither of these associations were verified. Concerning functional dependence individual items such as ‘control over work content’ (for both sexes) significantly reduced the risk of developing ADL-dependence. The associations remained stable after medical diagnoses were additionally taken into consideration. The results of our study highlight the influence of occupational factors beyond working life and support the importance of starting geriatric health promotion before retirement age.

Background
Liver transplantation is performed at large transplant centers worldwide as a therapeutic intervention for patients with end-stage liver diseases.Aim
To analyze the outcomes and incidence of liver transplantation performed at the University of São Paulo and to compare those with the State of São Paulo before and after adoption of the Model for End-Stage Liver Disease (MELD) score.Method
Evaluation of the number of liver transplantations before and after adoption of the MELD score. Mean values and standard deviations were used to analyze normally distributed variables. The incidence results were compared with those of the State of São Paulo.Results
There was a high prevalence of male patients, with a predominance of middle-aged. The main indication for liver transplantation was hepatitis C cirrhosis. The mean and median survival rates and overall survival over ten and five years were similar between the groups (p>0.05). The MELD score increased over the course of the study period for patients who underwent liver transplantation (p>0.05). There were an increased number of liver transplants after adoption of the MELD score at this institution and in the State of São Paulo (p<0.001).Conclusion
The adoption of the MELD score led to increase the number of liver transplants performed in São Paulo. 相似文献57.

Internal derangements of the temporomandibular joint: findings in the pediatric age group 总被引:1,自引:0,他引:1
Findings in 31 pediatric patients with pain and dysfunction of the temporomandibular joint (TMJ) are reported. The average age was 14 years (range, 8-16) and the average duration of symptoms was 21.4 months (range, 3 mo.-5 yr.). Internal derangements were found in 29 patients (94%) and degenerative arthritis in 13 (42%). In 12 patients (39%), the problem could be traced to an injury to the jaw. Secondary condylar hypoplasia was associated with the meniscal abnormality in 3 patients (10%). Further awareness of internal derangements of the TMJ in the pediatric population should permit greater recognition of their etiology. It is important that treatment be initiated as soon as possible, not only to minimize the development of osseous disease in young adults but also to prevent facial growth deformities. 相似文献

Forty infants and children were accurately diagnosed with real-time ultrasound (US) as having megaloureter secondary to ureterovesical junction (UVJ) obstruction by an adynamic, distal ureteral segment. Characteristic US findings were dilatation of the distal ureter, often disproportionate to the appearance of the upper collecting system; lower ureteral hyperperistalsis; and a sharply tapered, incurving, distal adynamic segment, 1-3 cm long. Real-time US, used routinely in preliminary evaluation of the urinary tract in children, can facilitate early diagnosis of UVJ obstruction and thus prevent significant loss of renal function. 相似文献
