This paper reviews the advantages and disadvantages of medical quality assurance methods commonly used in hospitals. A computer-based literature search up to April 1993 was done using the terms quality assurance, quality control, audit, utilization review, accreditation, occurrence screening and total quality management. In addition, a manual search was undertaken of references of papers obtained by the computer search and of the contents of the following journals: Quality Review Bulletin, Australian Clinical Review and the British Medical Journal. An assessment of the advantages and disadvantages of 15 quality assurance methods used in hospitals was made. Many quality assurance methods used in hospitals have significant disadvantages. A systematic method that provides meaningful and useful information to clinicians and improves patient care is urgently required. New methods such as occurrence screening and total quality management are slowly emerging and have much potential. 相似文献

Self-help therapy books, cassettes, and other materials are often antiscientific and shoddy, but they also frequently have several solid advantages, help some people to make profound personality changes (with and without regular therapy), and may well effectively influence many more people in the US (and even more so throughout the world) than do professional psychotherapists. It would be preferable if self-help materials were pretested and posttested in a manner similiar to that of researching the reliability and validity of psychological tests.

Until recently, chimpanzees were considered susceptible to human immunodeficiency virus type 1 (HIV-1) infection, but refractory to disease induction based on the asymptomatic status of all experimentally infected chimpanzees after over 10 years postinfection (PI). However, a decline in peripheral CD4+ T cells was noted in one chimpanzee (C499) of the Yerkes cohort of HIV-1 infected apes, after 11 years PI concurrent with increasing plasma viral load. These clinical signs were followed by the occurrence of opportunistic infections, thrombocytopenia, and progressive anemia leading to euthanasia. A second chimpanzee (C455) was transfused with blood from C499 collected during the symptomatic stage. Shortly thereafter, this second animal showed a rapid decline in peripheral CD4+ T-cell levels and sustained high viral load. Hematological analyses showed a 50% decrease in CFU-GM for both apes during the symptomatic phase and a reduction of 40% and 73% of the total CFU despite normal levels of CD34+ cells in the bone marrow. Cryopreserved sequential PBMC samples from these two chimpanzees were analyzed for constitutive and PHA-P induced levels of cytokines and chemokines. Data show that whereas there were no detectable constitutive levels of mRNA coding for IL-2, 4, and 10, there appears to be a transient increase in IFN-gamma message level coincident with increased viremia and this IFN-gamma synthesis decreased with disease progression. PHA-induced cytokine mRNA analysis showed low or undetectable levels of IL-4 and IL-10 mRNA in all samples and a marked decrease in the levels of IL-2 shortly after HIV infection. In addition, there was also a gradual decrease in IFN-gamma mRNA with progression of disease. Of interest were the findings of high to normal levels of PHA-induced synthesis of the chemokines MIP-1alpha, MIP-1beta, and RANTES in samples during the asymptomatic and early symptomatic period, which also dramatically decreased at late stages of the disease. These data suggest important roles for IL-2, IFN-gamma, and the chemokines in the regulation of immune responses in HIV-1-infected chimpanzees. 相似文献

Phytotherapy is a medicinal and ancestral practice in Africa. It deals with all the fields of human pathology. We wanted to ascertain the efficacy of some plants used in odontology as Euphorbia balsamifera traditionally used as antalgic treatment of acute dental pulpitis. The latex of the plant was caught and treated as to get enough stable paste. We used that paste in the same conditions we use arsenical nerve caustics, a pulpal devitalizer widely used in dental offices. The study carried out on 37 teeth has shown that latex of Euphorbia balsamifera is an effective pulpal devitalizing in contact with the pulp. Its lifetime action was comparable to that of the pulpal nerve caustics. The active principles are not known, however the product seems attractive as a pulpal devitalizing agent. 相似文献
