A mesenteric cyst with milk of calcium in an adult patient is presented. Preoperative evaluation included plain film, ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI). To our knowledge, the presence of milk of calcium in a mesenteric cyst has not been previously described. 相似文献

We present, to our knowledge, the first extensively studied case of lymphoid L2 blast crisis of chronic myelogenous leukemia with a hand mirror cell (HMC) variant. Special stains revealed the leukemic cells to be terminal deoxynucleotidyl transferase positive by immunofluorescence and cytochemically positive for alpha-naphthyl acetate esterase and acid phosphatase (diffuse granular). Immunophenotyping identified the major leukemic cell population as B-cells that expressed CD10+, CD19+, and HLA-DR+. It was not possible to separate the HMC and the non-HMC leukemic population by gating various cell populations, dual staining, cytochemistry, or by terminal deoxynucleotidyl transferase. Gene rearrangements were observed in both Ig heavy-chain alleles and one T-cell antigen receptor gamma-subunit allele. The rearrangements occupied all of the cells, indicating that the HMC and non-HMC were of a common clonal origin. The patient had a mosaic karyotype, with 90% of the cells having t(9;22), t(8;14), and t(9;15) translocations, an additional chromosome 8, and deleted chromosomes 9 and 15. Antibodies to simian sarcoma-associated virus and baboon endogenous virus were isolated in the patient's peripheral blood plasma. 相似文献

A study of 53 individuals failed to reveal an association between any HLA antigen and endometriosis. Division of the sample into those having a relative affected with endometriosis (N = 11) and those not having such a relative (N = 42) similarly failed to reveal significant associations. 相似文献

In a time of decreasing resources, managers need a tool to manage their resources effectively, support clinical requirements, and replace aging equipment in order to ensure adequate clinical care. To do this successfully, one must be able to perform technology assessment and capital equipment asset management. The lack of a commercial system that adequately performed technology needs assessment and addressed the unique needs of the military led to the development of an in-house Technology Assessment and Requirements Analysis (TARA) program. The TARA is a tool that provides an unbiased review of clinical operations and the resulting capital equipment requirements for military hospitals. The TARA report allows for the development of acquisition strategies for new equipment, enhances personnel management, and improves and streamlines clinical operations and processes. 相似文献

Plasmapheresis followed by intravenous immunoglobulin in presensitized patients awaiting thoracic organ transplantation. 总被引:2,自引:0,他引:2
Four highly sensitized patients awaiting thoracic organ transplantation were treated immediately preceding transplantation with 1 plasmapheresis and infusion of high dose intravenous immunoglobulin (IVIG). All 4 underwent successful surgery and have had minor to no rejection episodes over a range from 5 1/2 to 12 months. All panel reactive antibodies (PRA) were dithiotheitol (DTT) resistant, and 1 patient had IgG specific alloantibodies to a donor alloantigen. All 4 patients had positive donor cross matches prior to transplantation, and 3 of the 4 patients remained PRA negative for up to 9 months after allografting. Possible mechanisms of this therapy include inhibition of proliferating alloreactive B cells or suppression by antiidiotypic antibodies. Further study is warranted. 相似文献

A 22 year old male presented with symptoms of diffuse muscle pain and multiple abnormal laboratory findings that were eventually attributed to tropical myositis. Computed tomography scan was more reliable than ultrasound and served as a guide to needle aspiration and pathologic diagnosis. 相似文献

A case register of multiple sclerosis (MS) was set up in the city of S?o Paulo, Brazil, situated at a latitude of 23-24 degrees south. Cases were notified by neurologists, neuroradiologists and by an association of patients with MS. Prevalence rate was 4.27 x 10(-5) (men: 2.89 x 10(-5); women: 5.59 x 10(-5)), with a preponderance of young adults. We discuss here whether these rates are artifact due to poor health care facilities, to poor notification and deficiencies in diagnosis, or whether these rates are really low. 相似文献
