Sebaceous carcinoma is uncommon, with fewer than 400 cases reported. Usually, lesions arise in the meibomian glands of the eyelid; however, extraocular lesions within the head and neck have been reported. Regardless of the location, sebaceous malignancies must be considered aggressive neoplasms with a potential for regional and distant metastasis. Diagnosis may be difficult, given the low incidence and inconsistencies in histopathologic classification. Recently, needle aspiration cytologic characteristics have been delineated, with this procedure becoming increasingly useful in establishing the diagnosis. Treatment requires wide surgical excision with removal of involved regional lymph nodes. Opinions are divided regarding the use of postoperative irradiation or chemotherapy. Records of all patients with sebaceous carcinoma of the head and neck treated at UCLA Medical Center, Los Angeles, over the last 35 years were reviewed. The clinical and pathologic features are discussed, and the literature is summarized. 相似文献

Little attention has been paid to how patients' personality traits interfere with the communication and the outcome of physician-patient interaction. We performed an experimental study with students with high and low trait anxiety as patients. One physician conducted a single consultation with 41 students applying two beforehand-specified consultation styles. Patients completed questionnaires concerning emotional state and satisfaction. The actual content of the consultations was analyzed by Roter interaction analysis system (RIAS). The physician gave more biomedical information to low-anxiety students than high-anxiety students. Students who provided a lot of biomedical information themselves were less tense after the consultation. However, students with high anxiety were more dependent on the physician actively asking biomedical questions for them to be able to deliver that same information. In contrast to low-anxiety students, those with high anxiety were less satisfied after consultations involving many psychosocial questions posed by the physician and a good deal of emotional talk on their own part. Compared to low-anxiety students, students with high anxiety were less satisfied and tenser after consultations with much positive emotional talk on the part of the physician. We conclude that physicians and educators should be aware that psychological and emotional communication may be experienced as intrusive and inappropriate by patients with high trait anxiety when they present minor somatic problems. 相似文献

Methodology for the computer analysis of 201T1 myocardial perfusion images has been developed by several laboratories. Substantial evidence of the advantage of this approach over visual inspection alone has been reported. The currently available computer analyses use different algorithms to analyze 201T1 kinetics in the myocardium. The authors evaluated and compared two widely used software programs, Medical Data System (MDS): a mean-count profile, and the Cedars Sinai (CS): a maximal-count profile, of planar 201T1 scintigraphy for their ability to detect coronary artery disease (CAD). 相似文献
