Hysterosalpingography was performed in 31 patients by means of a low-dose scanning-beam digital radiographic system. The technique permits adequate evaluation of gynecologic abnormalities while allowing significant reduction in radiation: 2.4-mR (6.1 X 10(-7) C/kg) exposure to the skin and 0.7-mrad (7 X 10(-6) Gy) mean dose to the ovaries per image obtained. Sixteen patients demonstrated readily recognizable and documented abnormalities, corroborated by laparoscopy, laparotomy, or other supportive evidence. 相似文献

A 36-year-old woman with newly diagnosed acne rosacea is presented. Her skin changes were noticeable only under closest scrutiny, but she quit her job, became despondent about her acne, and developed suicidal ideation. The diagnosis and treatment of this patient allow a broader discussion of the somatically focused patient whose ideation reaches delusional intensity. 相似文献

Kohl is a widely used traditional cosmetic. It is mainly worn around the eyes in the Middle East, Asia and Africa. The elemental composition of twenty-one kohl specimens originating from various parts of Saudi Arabia, India and the Middle East was determined by energy dispersive X-ray analysis (EDAX). The data indicates the presence of significant lead levels in two thirds (14/21) of the kohl specimens ranging from 2.9–100 (mean 48.5). Other less frequent elements present in kohl preparations include aluminum, carbon, iron, titanium, calcium, magnesium, oxygen, silver silicon, sulfur and antimony. Seven kohl specimens were totally lead-free, four had a lead content in the range of 2.9–34.1 and ten had lead levels in excess of 84. Carbon levels in excess of 60 were detected in six kohl samples. Antimony was present in only one kohl specimen at a concentration of 7.8.Five western made eyeliner pencils analyzed for comparative purposes consistently revealed iron as a common constituent (mean 46) but no lead or carbon were detected in these specimens.The findings of this study indicate that modern kohl preparations contain a number of metals derived from natural sources in addition to carbon. The predominance of lead in the kohl preparations tested is of major concern due to the documented adverse effects in humans and the increased susceptibility of children to lead intoxication. Application of lead-containing kohl needs to be considered as a source of lead in evaluating patients with symptoms of lead intoxication in regions where this tradition prevails. The documented toxic effects of lead in humans and the increased sensitivity of children to lead exposure serve to emphasize potential health risks of using traditional lead containing kohl preparations and the need for increased surveillance and regulation of the manufacture of kohl.The opinions or assertions contained herein are the private views of the author and are not to be construed as official or as reflecting the views of the Department of the Army or Department of Defense. 相似文献

Solitary bronchioloalveolar carcinoma: CT criteria 总被引:14,自引:0,他引:14

The computed tomographic (CT) scans of 30 patients with solitary bronchioloalveolar carcinoma were reviewed. Common features at CT included the peripheral or subpleural location of a pulmonary mass (25 cases), pseudocavitation (18 cases), heterogeneous attenuation (17 cases), irregular margins forming a star pattern (22 cases), and pleural tags (21 cases). Using these CT criteria, four independent observers attempted to identify cases of bronchioloalveolar carcinoma from a larger sample of lung cancers and benign lesions by categorizing a series of test cases into four probability categories. Although the bronchioloalveolar carcinomas were correctly ranked in the two highest probability categories 75% of the time (in 45 of 60 cases), there was considerable overlap with other lung lesions, particularly with adenocarcinoma and large cell undifferentiated carcinoma. However, even though the typical features of bronchioloalveolar carcinoma are not invariable or highly specific, they are characteristic enough to suggest the diagnosis. 相似文献
