A clinical and immunologic study of employees in a facility manufacturing trimellitic anhydride.

We conducted a 1-year cross-sectional survey of 474 employees of a large chemical manufacturing complex to relate trimellitic anhydride (TMA) exposure to serologic and clinical outcomes. In 1988-1989, employees were evaluated by history and immunologic assay of total (T) and IgE antibody to trimellityl human serum albumin (TM-HSA). All employees were assigned to a TMA exposure class, from 1 (highest) to 5 (lowest), by an industrial hygienist, independent of the clinical and immunological data. Thirty-two (6.8%) of 474 employees had a TMA immunologic syndrome, 31.6% with an irritant response and 61.6% with no symptoms. Twelve had asthma/rhinitis, 10 had the late respiratory systemic syndrome (LRSS), four had late onset asthma, one had late onset arthralgia, and five had a distant history of LRSS. Included in this survey of the entire work force were 321 new enrollees, who had not joined the previous (1976 to 1988) voluntary surveillance program. Only four (1.3%) of the new enrollee group had a TMA immunologic syndrome. Among new enrollees, there were lower mean total and IgE serum antibody levels in lower exposure classes and a higher percentage with elevated antibody levels in high exposure classes (for T, x2 = 17.5, p = .0016; for IgE, x2 = 76.7, p less than .0001). In the new enrollee population, demographic variables of age, sex, date of hire, and smoking status were examined related to antibody levels. Only current or former smoking was related to elevated total antibody levels.

Quarantine stressing voluntary compliance.

A 1-day table-top exercise in San Diego, California, in December 2004 emphasized voluntary compliance with home quarantine to control an emerging infectious disease outbreak. The exercise heightened local civilian-military collaboration in public health emergency management. Addressing concerns about lost income by residents in quarantine was particularly challenging.

The knowledge, attitude and practice of voluntary counselling and testing (VCT) for HIV/AIDS among undergraduates in a polytechnic in southeast, Nigeria.

BACKGROUND: The identification of infected individuals is an important step in the control of the HIV epidemic. Voluntary counselling and testing (VCT) for HIV/AIDS is a concept developed in this direction. The objective of this study is to determine the level of knowledge, attitude and practice of Voluntary Counselling and Testing (VCT) for HIV/AIDS among undergraduates in a Nigerian tertiary institution. METHOD: This is a cross sectional study using a multistage sampling method to enroll students from different levels of the national diploma programme into the study. A structured questionnaire was administered to the 260 students with response rate of 70%. RESULT: Only 115 (63.2%) of the students were aware of VCT with 68 (59.1%) having heard of it at least one year prior to the study. Mass media and Churches were the highest sources of information on VCT Most of the students did not know where VCT services could be obtained and knowledge of what VCT entails was also low. However, 127 (69.8%) students approved the necessity of counselling prior to testing and 117 (64.3%) were ready to take a positive result in good fate. At least one out of every four students (54 of 182) had been sexually active within three months preceding the study Only 48 (26.4%) students had taken an HIV test at one time or the other before the study. Majority (62.5%) of those who had been tested went for the screening just to know their HIV status. Premarital testing (18.8%) was the second commonest reason for taken an HIV test. Majority of the respondents (74.2%) were willing to go for VCT Among those who were not willing to go for VCT the commonest reason given was that they were certain they were not infected. CONCLUSION: This study highlights the need to step up efforts to increase the students' awareness of VCT, deepen their knowledge and create the right attitude towards VCT through the mass media and religious bodies. Teaching on HIV/AIDS and VCT should also be incorporated into the school curriculum. A shift from the present clinic based approach to a more routine and widespread public health model will increase access to VCT Stand alone VCT centres should therefore be cited in educational institutions, community centres, marketplaces, youth friendly centres etc. for proximity to the people.

Attitudes of patients towards voluntary human immunodeficiency virus counselling and testing in two Nigerian tertiary hospitals.

BACKGROUND: Despite new scientific evidence establishing the benefits of counselling and testing as key elements in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) prevention strategy, inappropriate HIV screening without consent and counselling is frequent in Africa. Presumed high rejection rate of HIV test has been adduced to this practice. OBJECTIVE: To determine the acceptability of HIV conselling and testing among Nigerians. METHODS: Consecutive sixty indigenous Nigerians aged 35.10+/-11.31 years with male: female ratio of 2:1, and made of clients with clinically suspected AIDS (20), diseases unrelated to AIDS (15), dermatological problems (10), sexually transmitted diseases (9), and asymptomatic persons (6) were studied. RESULTS: Fifty-three (88.3%) subjects gave informed consent to HIV screening. Of the 53 consenters, 32 (60.4%) were seropositive while 21 (39.6%) were seronegative. Five clients (9.4%) (1seropositive + 4 seronegative consenters) did not turn up for their results, and 2 (3.8%) seronegative consenters did not want to know their serostatus. The reactions to disclosure of seropositive results included grief 9 (28.1 %), indifference 8 (25 %), surprise 5 (15.6%), family concern 5 (15.6%), denial 3 (9.4%) and suicidal ideation 2 (6.3%). Thirteen (40.6%) seropositive clients showed willingness to disclosure of their serostatus to family members including the father (58%), senior brother (23%), wife (11%) and others (8%). Direct cost of screening was N400.00 (U$3.10) per client. An average of 18 minutes per client was spent on counselling. CONCLUSIONS: This study demonstrates the feasibility of VCT in Nigerian hospitals.

Hospitalisations for rotavirus gastroenteritis among children under five years of age in New South Wales.

OBJECTIVE: To estimate the number of children under five years of age hospitalised for rotavirus gastroenteritis in New South Wales. DESIGN: Retrospective survey with comparison of patterns of hospital admissions for acute gastroenteritis in children under five with laboratory reports of rotavirus infection. SETTING: New South Wales, January 1991-December 1993. OUTCOME MEASURES: Laboratory reports of rotavirus infection to the Eastern Sydney Laboratory Surveillance Program (a voluntary laboratory reporting scheme) and hospital admissions of children under five with principal diagnosis classified under international classification of diseases, 9th revision, clinical modification (ICD-9-CM) codes 008.6, 008.8, 009.0-009.3 and 558.9 from NSW Inpatient Statistics Collection. RESULTS: Rotavirus infections were reported throughout each year (mean, 57 reports per month), with incidence peaks in August or September. Admissions for gastroenteritis showed the same seasonal pattern (correlation coefficient, 0.93). About 3700 children under five were admitted for rotavirus gastroenteritis annually in NSW at an estimated annual cost of 4.6 million dollars. Annual rates were highest for children aged 12-23 months (1800 per 100000 population in age group), intermediate for those aged 0-11 and 24-35 months (810 and 1000 per 100000 in age group, respectively) and lowest for those aged 36-47 and 48-59 months (450 and 190 per 100000 population, respectively, in age group). CONCLUSIONS: Rotavirus is a major cause of morbidity among young children in NSW. Routine infant vaccination against rotavirus could reduce this morbidity and the resulting health costs.

National Study of Internal Medicine Manpower: XIII. The financing of internal medicine residency and fellowship training, 1985 to 1986.

Hospital revenue is the most important source for residency and fellowship stipends in internal medicine. Medicare is especially important for residency programs in voluntary hospitals and hospitals not closely affiliated with a medical school. In the last decade state and local government support and federal training grant support for residency stipends declined, whereas Veterans Administration support increased. Fellowship stipend sources are much more diverse; federal training grants, professional fees, foundations, medical school funds, and research grants contribute significantly. Medicare support appears to be focused on subspecialties particularly important to the elderly, including critical care, rheumatology, cardiology, hematology, gastroenterology, and nephrology. Geriatric medicine, however, receives substantial Veterans Administration support. With growing revenue constraints and increasing concerns about excess physicians we need to monitor the impact of government regulations and other factors on funds available for training internal medicine specialists.

Voluntary screening for human immunodeficiency virus (HIV) infection. Weighing the benefits and harms.

Voluntary screening for human immunodeficiency virus (HIV) infection may help prevent the spread of the HIV epidemic if persons who test positive alter behaviors that may transmit infection. Protecting persons from unknowingly being exposed to HIV infection must be balanced against respecting the autonomy of individuals being screened. Seropositive patients may feel a stigma and be subjected to discrimination if confidentiality of test results is breached. In patients without high-risk behaviors, the positive predictive value of HIV testing may be substantially increased if tests are done in reference laboratories and if further confirmatory tests are run on a second blood specimen. For persons with high-risk behaviors, HIV testing can be recommended to those who want to reduce uncertainty about their HIV status or whose medical care would change if they were seropositive. Health care workers can maximize benefits of screening and minimize harm by educating and counseling patients before HIV testing, discussing the confidentiality of HIV test results, urging patients to disclose positive test results to sex partners, and advising patients on how to reduce high-risk behaviors.

A decision analysis of mandatory compared with voluntary HIV testing in pregnant women.

BACKGROUND: The benefit of antiretroviral therapy in reducing maternal-fetal transmission of HIV during pregnancy has caused a public policy debate about the relative benefits of mandatory HIV screening and voluntary HIV screening in pregnant women. OBJECTIVE: To evaluate the benefits and risks of mandatory compared with voluntary HIV testing of pregnant women to help guide research and policy. DESIGN: A decision analysis that incorporated the following variables: acceptance and benefit of prenatal care, acceptance and benefit of zidovudine therapy in HIV-infected women, prevalence of HIV infection, and mandatory compared with voluntary HIV testing. MEASUREMENTS: The threshold deterrence rate (defined as the percentage of women who, if deterred from seeking prenatal care because of a mandatory HIV testing policy, would offset the benefit of zidovudine in reducing vertical HIV transmission) and the difference between a policy of mandatory testing and a policy of voluntary testing in the absolute number of HIV-infected infants or dead infants. RESULTS: Voluntary HIV testing was preferred over a broad range of values in the model. At baseline, the threshold deterrence rate was 0.4%. At a deterrence rate of 0.5%, the number of infants (n = 167) spared HIV infection annually in the United States under a mandatory HIV testing policy would be lower than the number of perinatal deaths (n = 189) caused by lack of prenatal care. CONCLUSIONS: The most important variables in the model were voluntary HIV testing, the deterrence rate associated with mandatory testing compared with voluntary testing, and the prevalence of HIV infection in women of child-bearing age. At high levels of acceptance of voluntary HIV testing, the benefits of a policy of mandatory testing are minimal and may create the potential harms of avoiding prenatal care to avoid mandatory testing.

The selling of organs, the sharing of self.

Hailed as a possible solution to the chronic shortage of transplantable organs, a commercial market raises a host of practical and policy problems. More important, it fails to give due respect to the body, the medium through which the self is revealed to the world.

The consequences of disclosure: one hospital's response to the presence of an HIV-positive physician.

Health care administrators are having to confront the many and complex problems associated with patient fears about the transmissibility of the HIV virus. Particularly acute are concerns that are raised when the physicians are HIV-positive or have AIDS. This article presents a case history of how one hospital handled the problems created by the announcement by one of its emergency room physicians that he was HIV-positive. The hospital's response--which included disclosure to the community, the full cooperation of the physician, provision of free counseling, and HIV testing--and the aftermath of this AIDS-related event are described. This case is discussed in relationship to the ongoing debate about the ethics and consequences of disclosure of the HIV status of health care workers.
