Abstract: We report a patient with cutis marmorata telangiectatica with the hitherto unreported anomaly of a double aortic arch. The presence of two major vascular anomalies in this patient may be secondary to a developmental defect of the mesoderm during embryogenesis. 相似文献

There is a severe lack of information on sexuality for any woman with a disability. Often, what is available is limited to material on birth control and child delivery. For women who are disabled and lesbian, virtually no written information exist and health care workers seldom feel comfortable discussing the topic. Lesbians with disabilities have the responsibility to discuss sexual preference with their health care workers. Yet, there is much to lose. This paper discusses the issues of being lesbian and disabled as well as the unique problems faced by their partners. Finally, the article discusses negative attitudes of health care workers toward both disability and homosexuality. 相似文献

Perfluorochemicals as US contrast agents for tumor imaging and hepatosplenography: preliminary clinical results 总被引:3,自引:0,他引:3

In animals, perfluorochemicals (PFCs) are effective ultrasound (US) contrast agents that produce hepatic, splenic, and tumor enhancement. The use of Fluosol-DA 20%, an emulsion of perfluorodecalin and perfluorotripropylamine, was studied in nine non-critically ill patients with cancer who had liver lesions. US studies without Fluosol were compared with studies obtained 24, 48, and 72 hours after Fluosol infusion. Vital signs and extensive laboratory analyses are performed before and after Fluosol infusion. Liver metastases from colonic, pancreatic, and gastric carcinoma exhibited rim or diffuse enhancement after a Fluosol dose of 1.6 g/kg or greater. Fluosol produced echogenic enhancement of the liver and spleen relative to kidney at a dose of 2.4 g/kg, allowing the detection of nonenhancing lesions. In addition, Fluosol at a dose of 1.6 g/kg or greater allowed detection of lesions not seen before contrast medium was administered in three of the seven patients studied. There was a mild increase in the level of serum glutamic oxaloacetic transaminase in two patients, one given 2.4 and the other 3.2 g/kg of Fluosol. Mild and transient allergic reactions without change in vital signs were experienced by two patients. 相似文献

Fifty-four specimens from patients undergoing radical prostatectomy for clinically confined prostate cancer between 1983 and 1987 were reviewed to determine the potential for flow cytometric (FCM) analysis of DNA ploidy and replication rate to predict disease recurrence. Each specimen was deparaffinized for FCM analysis and the pathology slides were reviewed by a single pathologist. FCM characteristics were correlated with pathological grade and stage, and both were correlated with disease status. In this series of patients, routine FCM analysis of DNA ploidy and replication rate failed to significantly enhance the ability of standard histopathological grading to predict disease recurrence in patients having clinically localized prostate cancer. Aneuploid tumors pathologically confined to the prostate did not appear to negatively affect prognosis. 相似文献

The mortality of squamous cell carcinoma of the tongue has not significantly improved in decades. Much of the information that has been gathered to date has been based on retrospective analyses. There is little consensus on treatment of the disease. In an attempt to define an objective prognostic indicator of aggressiveness of these tumors, a retrospective analysis of 15 paraffin-embedded specimens using flow cytometry was performed. Ten patients (67 percent) had aneuploid tumors and had a 5 year disease-free survival rate of 33 percent, whereas patients with diploid tumors (33 percent) had a 5 year disease-free survival rate of 80 percent. Although the number of patients was small, it appears that flow cytometry may be an objective prognostic indicator in patients with squamous cell carcinoma of the tongue. Larger series of archival paraffin-embedded flow cytometry analyses are recommended, as well as examination of variables other than the disease-free survival rate. 相似文献
