| [computerized patient-monitoring in the o.r (author's transl)]. | the routinely performed data-aquisition and its analysis by means of a computerized patient-monitoring-system will reduce the repetitive and often monotonous task of data collection accompanied by accuracy and objectivity as much as possible. another and equally important point for the anesthesiologists is to remove some of the pencil-and-paper burden, reduce the possibilities of human errors in reading instruments and note-taking and the rapid retrieval of monitored and stored data for the purp ... | 1975 | 1233480 |
| a code of ethics for a community mental health program. | the orange county department of mental health developed a code of ethics to give its variety of employees a single set of standards for patient care and professional behavior in a community mental health program. the need for the code grew from problems of role definition and interdisciplinary collaboration that repeatedly arose during the program's development. general principles for the code were extracted from various professional codes, from issues arising in the day-to-day workings of the p ... | 1976 | 1245312 |
| epidemiology of influenza in the elderly: evidence of virus recycling. | during the hong kong influenza epidemic of 1968-1969 the attack rate among persons born prior to 1890 was about one-third the rate among persons born after 1899. during an asian influenza epidemic in the same community two years earlier there was no apparent age effect. most persons born before 1890 had detectable pre-epidemic antibody against a/hong kong/68 whereas most persons born after 1899 had no detectable pre-epidemic antibody. the lower attack rate in the older age group is consistent wi ... | 1976 | 1251831 |
| hiv prevention and the two faces of partner notification. | in the cases of medical patients with sexually transmitted diseases (particularly those with the human immunodeficiency virus), two distinct approaches exist to notifying sexual and/or needle-sharing partners of possible risk. each approach has its own history (including unique practical problems of implementation) and provokes its own ethical dilemmas. the first approach--the moral "duty to warn"--arose out of clinical situations in which a physician knew the identity of a person deemed to be a ... | 1992 | 1304728 |
| seroepidemiology of viral infections among intravenous drug users in northern california. | intravenous drug users are frequently exposed to parenterally transmitted viral infections, and these infections can spread to the general population through sexual activity. we investigated the prevalence of serologic markers for human immunodeficiency virus type 1 (hiv-1), human t-cell lymphotropic virus type i/ii (htlv-i/ii), hepatitis b virus (hbv), and hepatitis c virus (hcv) in intravenous drug users and their sexual contacts. of 585 drug users from northern california tested for these ser ... | 1992 | 1310362 |
| arboviral disease--united states, 1991. | during 1991, state and local health departments reported 122 cases of human arboviral encephalitis to cdc. more than half (69) of the cases resulted from outbreaks of st. louis encephalitis (sle) in arkansas and texas. in addition, an epizootic of eastern equine encephalitis (eee) extending from the atlantic and gulf coasts into the upper midwest caused sporadic human cases and a substantial loss of livestock. this report summarizes the reported cases of arboviral encephalitis in the united stat ... | 1992 | 1321947 |
| clinical, epidemiologic, and virologic studies in four clusters of the chronic fatigue syndrome. | the purpose of this study is to provide a case definition of chronic fatigue syndrome in an outbreak occurring in the nevada-california region to evaluate candidate etiologic agents and observe the natural history of the illness. | 1992 | 1323246 |
| comparison of indirect immunofluorescence and membrane fluorescence assays for the differentiation of antibodies to human immunodeficiency virus types 1 and 2. | serum samples from 20 human immunodeficiency virus type 1 (hiv-1)- and 30 hiv-2-infected and 7 dually infected individuals were reacted by using the indirect immunofluorescence assay (ifa) and membrane fluorescence assay in order to determine whether these methods were useful for typing hiv-1 and hiv-2 antibodies. although 41 of 50 (82%) of the hiv-1- and hiv-2-positive specimens cross-reacted to some extent with the heterologous antigen in the ifa, the antigen with the higher titer correlated c ... | 1992 | 1328285 |
| serum epoxide hydrolase (preneoplastic antigen) in human and experimental liver injury. | reports of an increase in a serum epoxide hydrolase (seh), immunochemically related to microsomal eh in humans and rats with hepatocellular carcinoma (hcc), suggested its use as a serum marker for this disease. we have now measured seh levels (as either immunochemically determined content or enzyme activity) in a number of human and experimental models of liver disease. seh was elevated above the normal range in at least 50% of individuals with hcc, including: 3 of 6 northern californians; 4 of ... | 1992 | 1339049 |
| forecasts of the costs of medical care for persons with hiv: 1992-1995. | this study concludes that the cumulative (national) cost of treating all persons with the human immunodeficiency virus (hiv) rose considerably over the past year and will continue to rise over the next several years. it is forecast that the cumulative cost of treating all persons with hiv will increase 48% from 1992 to 1995 (from $10.3 billion to $15.2 billion). it is estimated that the average yearly cost of treating a person with aids is $38,300 and of treating an infected person without aids ... | 1992 | 1356925 |
| seroepidemiology of california and bunyamwera serogroup bunyavirus infections in humans in california. | several human populations in california were surveyed cross-sectionally and longitudinally for neutralizing antibodies to selected arthropod-borne bunyaviruses in the california and bunyamwera serogroups. overall, the prevalence of antibodies to california serogroup viruses was 6.4% in 702 individuals sampled during 1963-1988. comparative antibody titers in individual sera indicated that 4.1% and 1.6% of these infections were caused by viruses similar or identical to jamestown canyon and califor ... | 1992 | 1357960 |
| molecular cloning and sequence analysis of an isolate of hepatitis c virus from southern california, u.s.a. | we obtained a cdna clone representing a partial rna sequence of a human hepatitis c virus (hcv) isolate from southern california. rna was extracted from the liver tissue of a patient with post-transfusion hepatitis, and used for cdna synthesis and polymerase chain reaction (pcr) amplification using oligonucleotide primers specific for the prototype hcv rna. the cdna clone obtained contains 585 base pairs of hcv sequences and represents the region encoding the putative nonstructural protein ns3 o ... | 1992 | 1364214 |
| the risk management of infections. | unfortunately, risk management, that is avoiding lawsuits, is a retro-active pastime instead of being pro-active. what this means is that we often take action only after a problem has manifested itself, rather than identifying potential problems and correcting them. this is, however, only human nature and occurs in most other walks of life. in dental malpractice, what appears to have been happening during the past few years in california is that plaintiff's lawyers have identified a problem and ... | 1992 | 1389588 |
| risk for aids in multiethnic neighborhoods in san francisco, california. the population-based amen study. | to examine the actual and potential spread of human immunodeficiency virus (hiv) from an acquired immunodeficiency syndrome (aids) epicenter to surrounding neighborhoods, we studied the prevalence of the viral infection and aids risk behaviors from 1988 to 1989 in a representative sample of unmarried whites, african americans, and hispanics living in san francisco. we surveyed 1,770 single men and women aged 20 to 44 years (a 64% response rate) in a random household sample drawn from 3 neighborh ... | 1992 | 1413740 |
| health care use by human immunodeficiency virus-infected students at a california student health service. | we report characteristics of 16 college students with human immunodeficiency virus (hiv) infection but without the acquired immunodeficiency syndrome who received care at a student health center at a major university in california. sociodemographic and clinical data and medical expenditures were obtained retrospectively from medical charts and computerized billing records. all 16 students were men who had sex with men, and 3 had also used intravenous drugs. dermatologic conditions, upper respira ... | 1992 | 1413741 |
| high-risk sexual behavior and condom use among gay and bisexual african-american men. | little is known about the human immunodeficiency virus (hiv) high-risk sexual practices of gay and bisexual african-american men. these data are needed so that better interventions can be developed and implemented in this population. | 1992 | 1443298 |
| screening women of childbearing age for human immunodeficiency virus. a cost-benefit analysis. | in light of the increasing problem of perinatal human immunodeficiency virus (hiv) transmission, the issue of screening women for hiv is receiving considerable attention. we analyzed the costs and benefits of screening women of childbearing age for hiv. the analysis was based on a dynamic model of the hiv epidemic that incorporated disease transmission and progression, behavioral changes, and effects of screening and counseling. we found that the primary benefit of screening programs targeted to ... | 1992 | 1444682 |
