Eight lymphatic fluid collections were drained percutaneously. There were no immediate or late complications. Seven patients
had follow-up; 1 required surgical drainage of a residual or recurrent lymphocele, and another had reaccumulated fluid in
a lymphocele which was detected on autopsy. The remaining lymphatic collections responded to percutaneous drainage. Percutaneous
drainage is safe and can be an effective tool in the management of lymphatic collections. 相似文献

Information on the relative incidence of Crohn's disease and ulcerative colitis was obtained by a prospective investigation at six Melbourne teaching hospitals. One hundred and eleven patients who presented with chronic inflammatory bowel diseases between 1980-1981 were admitted to the study. Forty (36%) patients were diagnosed as having Crohn's disease and 63 (57%) patients as having ulcerative colitis. The type of chronic inflammatory bowel disease could not be determined in eight (7%) patients. These findings suggest that the relative frequency of Crohn's disease and ulcerative colitis in Melbourne hospitals is within the range that is reported for northern Europe and the United States. 相似文献

Deep granuloma annulare (DGA) is one of several lesions of skin and superficial soft tissues whose histologic character is
a palisading granuloma with a small central focus of necrosis or necrobiosis. Unlike the other palisading necrobiotic lesions,
DGA has a predilection for children in the first 5 to 6 years of life. A painless subcutaneous nodule(s) in the lower anterior
tibial region or foot and the scalp, typically in the occiput, was the most common presenting feature in this study of 35
cases. Additional or recurrent lesions were reported in approximately 70% of cases with clinical follow-up. All lesions showed
the presence of necrobiosis; however, one of the characteristic features was the multinodular character of the predominantly
mononuclear cellular aggregates. The presence of vascular spaces at the periphery of the nodular profiles served as a clue
to the diagnosis of DGA. The palisading arrangement of the mononuclear cells was evident only in those foci with central necrobiosis.
A histiocytic disorder or fibrohistiocytic process was a common consideration in the differential diagnosis, especially in
those cases with less apparent foci of necrosis. Palisading histiocytes with prominent eosinophilic cytoplasm and some nuclear
atypism were problematic with regard to possible epithelioid sarcoma. Our study failed to identify any underlying or predisposing
factors in the development of DGA. Despite the fact that DGA is a well-documented lesion in children, it occurs sufficiently
infrequently that it is often not considered clinically when it presents as a subcutaneous mass or masses in a child. Its
recognition by the pathologist is especially important as the occurrence of additional lesions in a high proportion of children
can be anticipated without undue concern.

The visit of Dr. Trendley Dean to Dublin in the mid-1950s helped accelerate the decision to introduce water fluoridation as a public health measure in the prevention of caries in the Republic of Ireland. A challenge to the constitutional validity of the Health (Fluoridation of Water Supplies) Act 1960 failed and in 1964 the water supplies of Dublin city were fluoridated. Over the next seven to eight years all the major urban communities in the Republic of Ireland were fluoridated. Currently, 67 percent of the 3.5 million people in the country reside in fluoridated communities. Studies conducted over the last 20 years show that residents of fluoridated communities have better dental health than those in nonfluoridated communities—the mean dmft is lower in children and the number of natural teeth present in adults is higher. 相似文献

A new technique for measuring intraosseous pressures involves inserting a miniature transducer directly into the intraosseous space. A high-performance, high-fidelity pressure transducer is easy to assemble and insert. The transducer permits dynamic studies of intraosseous pressure during gait, and constitutes a promising tool for detecting changes in intraosseous pressure in osteoarthritis and osteonecrosis. 相似文献

Digital radiography of subtle pulmonary abnormalities: an ROC study of the effect of pixel size on observer performance 总被引:3,自引:0,他引:3
Forty conventional radiographs with examples of mild interstitial infiltrates and subtle pneumothoraces and 40 normal studies of the chest were selected and digitized, with pixel sizes of 1.0, 0.5, 0.2, and 0.1 mm. Observer performance tests were carried out using receiver operating characteristic analysis. Conventional radiographs and digitized images were compared. The results indicate that, in such cases, diagnostic accuracy increases significantly as the pixel size is reduced, at least to the 0.1-mm level. We conclude that, for digital systems using screen-film or similar image receptors, use of a pixel size substantially larger than 0.1 mm may result in some loss of diagnostic accuracy. 相似文献
