Clinicopathologic material from 25 patients with lymphocyte-depleted Hodgkin's disease was reviewed. The median age of the patients was 57 years. The patients had no prior diagnosis of Hodgkin's disease and were divided according to pathologic subtype of lymphocyte-depleted Hodgkin's disease: 11 diffuse fibrosis, 10 reticular, and four not otherwise specified. The clinical presentation included B symptoms of fever, weight loss, or night sweats (92 percent), subdiaphragmatic disease (88 percent), frequent marrow involvement (56 percent), and advanced-stage disease (100 percent). Four of 11 patients with diffuse fibrosis had peripheral adenopathy as compared with seven of 10 patients with the reticular subtype (p = 0.3); 10 of 11 patients with diffuse fibrosis had marrow involvement compared with two of nine patients with the reticular subtype (p = 0.006). Among patients who received chemotherapy, median survival was longer in the diffuse fibrosis subtype (nine patients, 39 months) than in the reticular subtype (10 patients, 10 months), p = 0.005. Of the 17 patients who received more than one cycle of combination chemotherapy with mechlorethiamine, vincristine, procarbazine, and prednisone, the median survival was 36 months with 11 (65 percent) complete remissions. In eight patients, disease remains in remission (12 to 127 months) with five patients surviving beyond five years. These results indicate that lymphocyte-depleted Hodgkin's disease has at least two clinicopathologic subtypes and is curable if adequate therapy can be given.
The authors ascertained the incidence of hip fracture in Saskatchewan, Canada, residents aged 65 years or older for the 10 years 1976-1985 from computerized hospital discharge records and compared it with rates for several other populations in Northern Europe and the United States. In Saskatchewan, the average annual incidence was 5.5 per 1,000 person-years. The incidence in women was twice that in men, the incidence in urban areas was 27% greater than that in nonurban areas, and there was no secular trend of increasing rates. The incidence of hip fracture in Saskatchewan was lower than that for populations in Scandinavia and the United States but was comparable to rates in English populations. Further study is needed to elucidate the genetic, environmental, and behavioral factors responsible for this variation.
A workstation designed to facilitate electronic charting in the intensive care unit is described. The system design incorporates a graphical, windows-based user interface. The system captures all data formerly recorded on the paper flowsheet including direct patient measurements, nursing assessment, patient care procedures, and nursing notes. It has the ability to represent charted data in a variety of graphical formats, thereby providing additional insights to facilitate the management of the critically ill patient. Initial nursing evaluation is described.
Study of non-hip fractures, which are a serious public health problem for persons greater than or equal to 65 years of age, has been hindered by the absence of an economical method for case identification. We assessed the utility of computerized Medicare inpatient, emergency room, hospital outpatient department and physician claims for identifying fractures in an elderly Tennessee Medicaid population. We used these files for 1987 to identify 3086 possible fractures and reviewed medical records for a sample of 1440. Using this sample, we developed a definition of probable fractures that excluded claims unlikely to represent newly diagnosed fractures. For all fractures, this definition had a positive predictive value of 94%, which for individual fracture sites, ranged from 79% (tibia/fibula) to 98% (hip). Of fractures in the reviewed sample, 91% were identified as probable fractures; this upper bound for sensitivity varied between 75% (femoral shaft) and 100% (patella). These data suggest that computerized Medicare files can be used for rapid and economical fracture ascertainment among persons greater than or equal to 65 years of age. However, further work is needed to obtain better estimates of sensitivity.
