The Pliofilm cohort is the most intensely studied group of workers chronically exposed to benzene. Information on this cohort has been the basis for regulations and/or guidelines for occupational and environmental exposure to benzene. Rinsky et al. (1986, 1987) and Crump and Allen (1984) developed different approaches for reconstructing the exposure history(More)
We describe 35 peripheral lymph nodes classified as mantle cell/marginal zone B-cell hyperplasia with clear cells using morphologic and immunologic findings. For the purpose of this study, we obtained clinical follow-up information and performed immunoglobulin gene rearrangement studies on paraffin sections by polymerase chain reaction. Architecturally, the(More)
We identified 3 patients with autoimmune myelofibrosis (AM) lacking American Rheumatism Association criteria for systemic lupus erythematosus (SLE). They had 1 or 2 cytopenias and lacked serologic evidence for SLE. Autoimmune features included psoriatic arthritis and positive direct Coombs test (DCT) result, DCT-positive autoimmune hemolytic anemia, and(More)
Myelofibrosis is characterized by reticulin fibrosis of the bone marrow with resulting features of myelophthisis. Besides hematopoietic malignancies and other neoplasms involving the bone marrow, myelofibrosis has been described in association with autoimmune disorders, especially systemic lupus erythematosus. We describe the clinicopathologic features of a(More)

Using data from the National Institute of Mental Health and the Census Bureau, the authors examine trends in the delivery of mental health services over the past 40 years as they relate to number and types of facilities, utilization of services, diagnosis, and maintenance expenditures. The data show that during this period access to psychiatric services has(More)
Between 1970 and 1975 the number and rate of admissions to community mental health centers of people given a diagnosis of schizophrenia increased dramatically. However, the proportion of patients with schizophrenia admitted to community mental health centers declined because the increase in the rate of admissions of patients with schizophrenia was diluted(More)
