AIDS of childhood is reviewed in this timely article, including care of the child with infectious complications, and other current and future management concerns.

Viability of herpes simplex virus type 1 on the applanation tonometer

We performed several experiments to define possible factors that influence the viability of herpes simplex virus type 1 on the applanation tonometer. Infectious virus could be detected on experimentally inoculated tonometer heads for up to two hours during natural drying. If tonometers were kept moist the virus could be detected more than eight hours later. Several ophthalmic solutions, including topical anesthetics, dilating agents, and a fluorescein solution, showed only minimal antiviral activities. Wiping of virus-infected tonometer heads with a dry tissue was ineffective and allowed residual infectious virus to remain. However, no infectious virus could be detected on infected tonometer heads that had been swabbed with 70% isopropyl alcohol. Our results raised concerns regarding effective disinfection of tonometers after eye examinations. We concluded that the applanation tonometer should be swabbed routinely with alcohol after each patient examination to ensure complete virus inactivation and to prevent accidental transmission of virus in the clinical setting.

A review of AIDS-related legislative and regulatory policy in the United States

This article surveys proposals for public health statutes and regulations to control the spread of the human immunodeficiency virus (HIV). The data were collected by the Harvard School of Public Health in pursuance of a contract for the U.S. assistant secretary for health and by the Intergovernmental Health Policy Project at George Washington University. The intention is to provide a representative overview of legal and policy alternatives, not to offer a comprehensive account of statutes and proposals in all jurisdictions.

The AIDS epidemic has refocused attention on public health law, raising anew questions about the application, effectiveness, and constitutionality of various disease control measures. State and local legislatures have considered a broad range of measures designed to control the spread of AIDS. Virtually every state legislature has debated AIDS-related bills; between January 1 and April 15, 1987, more than 360 AIDS-related bills were introduced in the United States. Thus far, approximately twenty-eight states have enacted AIDS-related legislation.

AIDS as a social phenomenon

AIDS as a new lethal and at present incurable sexually transmitted disease is already having remarkable social repercussions not yet fully explicit and hence it can be termed a social phenomenon. Political, behavioural, economic and legal reactions and social responses such as stigmatization, changes in the sick role and the growth of voluntary organizations and international collaboration are described. Communication, education and information aspects of AIDS are considered using material from the press and it is clear that a massive educational approach to modify behaviour must be the basis for a control programme.

The epidemiology of the human immunodeficiency virus infection

It is nearly six years since the first evidence of the AIDS epidemic was seen, with the report of five cases of Pneumocystis carinii pneumonia diagnosed in young, otherwise healthy homosexual men in Los Angeles. The report was surprising, for although P. carinii is a common human commensal, the pneumonia essentially occurs only in the presence of severe immune suppression. Similar reports quickly followed from New York City and San Francisco, with the additional observation that Kaposi's sarcoma—a malignancy usually seen only in elderly men in this country—was also occurring epidemically among young homosexual men.

Since then, the epidemic has evolved at a relentless pace to a reported 32,000 cases in the United States by March 1987. The epidemic has sparked a massive multidisciplinary scientific effort, resulting in the successful identification of the causal agent—the human immunodeficiency virus (HIV)—within two years from the first report and producing a commercially available antibody test within four years.

Current issues in developing a strategy for dealing with the acquired immunodeficiency syndrome

A number of current issues exist that must be taken into account in the development of a strategy for dealing with the problem of the acquired immunodeficiency syndrome (AIDS) in the United States and throughout the world. Given the complexity of the problem and the fact that the epidemic is still in its evolving stages, such issues must be considered individually and as a group. The present discussion focuses on several of these critical issues and outlines approaches that might be useful in the formulation of basic scientific and public health strategies for dealing with the currently appreciated and projected problems in AIDS.

The genesis of fear: AIDS and the public's response to science

The AIDS (acquired immunodeficiency syndrome) crisis has aroused scientists to major research efforts and the public at times to near-hysteria. The media and their audience eagerly await the latest scientific reports, yet the public seems to respond selectively, embracing the most frightening interpretation of the data and discounting attempts to place those data in perspective. One might be tempted to conclude that questions of public health policy are best dealt with by expert judgment unsullied by lay opinion. Yet such an attitude supposes scientists to be governed by pure reason and to be beyond influence by narrow self-interest or by political or moralistic considerations, a self-serving assumption belied by an examination of the record. The erosion of public confidence in science has indeed bedeviled health authorities in their efforts to generate consensus on the policies they wish to implement, but the public response—including the response of scientists to AIDS—is a far more complex phenomenon.

AIDS in Africa: an epidemiologic paradigm

Cases of the acquired immune deficiency syndrome (AIDS) have been reported in countries throughout the world. Initial surveillance studies in Central Africa suggest an annual incidence of AIDS of 550 to 1000 cases per million adults. The male to female ratio of cases is 1:1, with age- and sex-specific rates greater in females less than 30 years of age and greater in males over age 40. Clinically, AIDS in Africans is often characterized by a diarrhea-wasting syndrome, opportunistic infections, such as tuberculosis, cryptococcosis, and cryptosporidiosis, or disseminated Kaposi's sarcoma. From 1 to 18% of healthy blood donors and pregnant women and as many as 27 to 88% of female prostitutes have antibodies to human immunodeficiency virus (HIV). The present annual incidence of infection is approximately 0.75% among the general population of Central and East Africa. The disease is transmitted predominantly by heterosexual activity, parenteral exposure to blood transfusions and unsterilized needles, and perinatally from infected mothers to their newborns, and will continue to spread rapidly where economic and cultural factors favor these modes of transmission. Prevention and control of HIV infection through educational programs and blood bank screening should be an immediate public health priority for all African countries.

Initial manifestation of acquired immunodeficiency syndrome in the head and neck region

Initial manifestation of AIDS in the head and neck region occurs frequently. The purpose of this report has been to alert the head and neck surgeon to the occurrence of AIDS-related lesions, their clinical characteristics, and disease outcome. Incomplete recognition of these disorders may delay appropriate diagnostic study and initiation of therapy. We have described 10 patients in whom the initial manifestation of AIDS-related malignancies occurred in the head and neck region. Six of these patients were found to have Kaposi's sarcoma, whereas four had non-Hodgkin's lymphomas. The specific clinical and pathologic aspects of the disease have been described, which represent common patterns of presentation. It is crucial to obtain an accurate social history, as well as a complete medical history from any patient suspected of having AIDS, and prompt biopsy of suspect lesions should be performed.

Transmission of human immunodeficiency virus (HIV/HTLV-III/LAV): a review

The literature on the transmission of human immunodeficiency virus (HIV/HTLV-III/LAV) is reviewed. HIV spreads by vertical transmission and by iatrogenic transmission (transfer of blood or blood-containing products), by infected needles among i.v. drug users and, more rarely, among health care workers, but mainly by sexual contact. In Western countries the virus is mainly spread by passive anal intercourse among homosexuals and seldom by heterosexual intercourse. In African countries, however, the virus is mainly spread by heterosexual intercourse, probably because of other, concurring sexually transmitted diseases. Some preventive measures are discussed.

Transmission of HIV infection to heterosexual partners but not to household contacts of seropositive haemophiliacs

The prevalence of HIV antibodies in 44 heterosexual female partners and 56 nonsexual family household contacts of 61 HIV seropositive haemophiliacs (41 adults and 20 children or adolescents) was determined to evaluate the risk of transmission of HIV infection. HIV antibodies were determined by enzyme-linked immunosorbent assay and positive reactions were confirmed by Western blotting. HIV antibodies were demonstrated in 4/40 (10%) regular heterosexual partners of 40 seropositive patients with haemophilia A. Four temporary heterosexual partners of one additional seropositive haemophiliac were seronegative. 56 nonsexual household contacts including 30 parents, 13 siblings and 13 children of 29 seropositive haemophiliacs were all negative for HIV antibodies. Thus transmission of HIV occurred from seropositive haemophiliacs to their heterosexual partners but not to nonsexual household contacts.
