Kaposi's sarcoma with a non-Hodgkin's lymphoma. Its association in a male homosexual with human T-cell lymphotropic virus type III infection
Combined tumor syndromes, specifically reticuloendothelial malignancies and Kaposi’s sarcoma, have long been recognized. With the recognition of the acquired immunodeficiency syndrome (AIDS), several patients with concurrent non-Hodgkin’s lymphoma and Kaposi’s sarcoma have been reported at high risk for developing AIDS. The present Centers for Disease Control definition of AIDS excludes these patients on the assumption that one tumor is affecting the cellular immunity, allowing for the development of the second malignancy. In evaluating such a patient who had serologic evidence of human T-cell lymphotropic virus type III infection, the probable cause of AIDS, we have reviewed reports of patients with similar concurrent malignancies before and since the onset of the AIDS epidemic. We conclude that patients in high-risk groups for AIDS who develop similar combined tumor syndromes should be classified as having AIDS
Understanding Early Faculty Experience: On Becoming Teachers, Scholars, and Community Members
This article focuses on findings from a qualitative study of the experiences of pretenured faculty within their first two years in the academy. The authors share narratives from faculty participants who are diverse in their disciplinary backgrounds and prior experiences, focusing on the expectations they had upon entering the profession, the challenges they encountered, and what they found helpful for meeting the many demands of faculty life. Their stories provide evidence of the enduring need for faculty learning communities. Implications of this work can inform the efforts of faculty developers, college and university administrators, and anyone with an interest in supporting tenure-track faculty
A four-dimensional probabilistic atlas of the human brain
The authors describe the development of a four-dimensional atlas and reference system that includes both macroscopic and microscopic information on structure and function of the human brain in persons between the ages of 18 and 90 years. Given the presumed large but previously unquantified degree of structural and functional variance among normal persons in the human population, the basis for this atlas and reference system is probabilistic. Through the efforts of the International Consortium for Brain Mapping (ICBM), 7,000 subjects will be included in the initial phase of database and atlas development. For each subject, detailed demographic, clinical, behavioral, and imaging information is being collected. In addition, 5,800 subjects will contribute DNA for the purpose of determining genotype-phenotype-behavioral correlations. The process of developing the strategies, algorithms, data collection methods, validation approaches, database structures, and distribution of results is described in this report. Examples of applications of the approach are described for the normal brain in both adults and children as well as in patients with schizophrenia. This project should provide new insights into the relationship between microscopic and macroscopic structure and function in the human brain and should have important implications in basic neuroscience, clinical diagnostics, and cerebral disorders
