Despite city, state, and federal programs to prevent LBW, decreases in infant mortality in the 1980s appear to be largely secondary to improved survival of LBW infants rather than to a decline in the rate of LBW births.… Read more
The latency period and/or incidence of the acquired immunodeficiency syndrome (AIDS) may differ in persons infected with the human immunodeficiency virus by different routes or having different “cofactors.” We compared 79 hemophilic men in Pennsylvania and 117 homosexual and bisexual men in California, all having known dates of infection and long postinfection observation periods, to examine these hypotheses.… Read more
We assessed the risk of human immunodeficiency virus (HIV) transmission from heterosexual seropositive hemophilic men to their female sex partners through an HIV serosurvey and questionnaire study conducted during 1984-1987. Five percent of 21 female partners of asymptomatic men and 11% of 35 partners of HIV-symptomatic (acquired immunodeficiency syndrome [AIDS], AIDS-related complex [ARC], peripheral generalized lymphadenopathy [PGL]) hemophilic men had been infected when first tested.… Read more
Hemophilia treatment centers were first established in the mid-1970s to provide optimal and coordinated medical care to patients with the disorder. Our study suggests that blacks with hemophilia may be receiving less coordinated care and less appropriate blood product therapy than whites with hemophilia.… Read more
Of 187 newborns admitted to a 33-bed, level III neonatal intensive care unit between January 1, 1985 and June 23, 1985, 33 developed necrotizing enterocolitis during their hospital stay. Twenty of the 33 newborns (61%) had onset of symptoms between April 1 and June 23, suggesting clustering during this period.… Read more
Cases of the acquired immune deficiency syndrome (AIDS) were first reported in June and July of 1981, as clusters of Kaposi’s sarcoma and Pneumocystis carinii pneumonia among homosexual men. Since then, epidemiologic surveillance has been used by investigators and public health professionals to identify that an outbreak existed, to characterize the outbreak, and to determine and predict its extent and course.… Read more
The Patient Knowledge Assessment Study (PKAS) was conducted among 107 male hemophilic patients, aged 15 to 67 years, at 19 hemophilia treatment centers (HTC). Participants were given a 30-item questionnaire concerning the cause of acquired immunodeficiency syndrome (AIDS), the groups at risk, and modes of transmission.… Read more
After almost a century of improvement, the rate of decrease in US infant mortality rates began to level off during the period of 1982 to 1984. Rates actually increased in some states. Because much of the decline in infant mortality in this century can be attributed to advances in infectious disease treatment and prevention programs, we evaluated the current impact of infectious diseases on infant mortality.… Read more
The time course of the epidemic of acquired immunodeficiency syndrome (AIDS) as it has occurred in the US hemophilia population is examined using surveillance data collected by the Centers for Disease Control (CDC). These data indicate that the epidemic course in hemophiliacs is distinguishable from that in the homosexual/bisexual and intravenous drug-using populations in at least one respect–the epidemic in the hemophilia population is characterized by a lack of consistent increase in the number of new AIDS cases in successive time intervals.… Read more
Public concern about the transmissibility of human T-cell lymphotropic virus type III/ lymphadenopathy-associated virus (HTLV-III/LAV) has been heightened by several reports suggesting the existence of an antibody-negative, virus-positive state in some asymptomatic sex partners of persons who are antibody-positive. We recently evaluated 88 household members and/or sex partners of persons with hemophilia and found that only two nonhemophiliacs were HTLV-III/LAV antibody-positive. … Read more
The risk of conjugal transmission of the HTLV-III/LAV virus associated with the acquired immunodeficiency syndrome (AIDS) in patients with hemophilia is unknown. To date, only a few instances of proven exposure to HTLV-III have been reported among sexual or family contacts of patients with hemophilia. … Read more
We evaluated the human T-cell lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV) antibody and immune status of 88 persons living with and/or sexual partners of 43 hemophiliacs, 12 of whom had AIDS, five of whom had AIDS-related complex (ARC), 17 of whom were clinically well but HTLV-III/LAV antibody positive, and nine of whom were well and HTLV-III/LAV antibody negative.… Read more

Human T-cell leukemia virus type I (HTLV-I) has been strongly implicated as the etiology of adult T-cell leukemia (ATL), a T-cell type non-Hodgkin’s lymphoma with leukemic manifestations in Japan, the Caribbean, and the southeastern United States. The prevalence of serum antibody specific for one core antigen of HTLV-I, p24, has been found to be high in patients with ATL, and higher in relatives of these patients than in general population controls.… Read more
Human T-cell leukemia virus (HTLV-I)
is known to be associated with certain hematologic malignancies, and a related virus, HTLV-III/LAV, might be the cause of AIDS. Some persons with AIDS have had evidence of HTLV-I infection. Unrelated to these findings, it has been suggested that HTLV-I is transmitted via blood products.… Read more
Thirty-four adult and pediatric hemophilia A and B patients and 50 nonhemophilic members belonging to 28 families were enrolled in August 1984 in a study of human T cell lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV) antibody status and T cell subpopulation numbers.… Read more
During the period of 1979 to 1983, 38 patients with cystic fibrosis (CF) at the CF center of St. Christopher’s Hospital for Children in Pennsylvania developed respiratory tract colonization with Pseudomonas cepacia. Seventeen (45%) of the patients with colonization died.… Read more
From mid-1977 to mid-1983 the Centers for Disease Control (CDC) has received reports of more than 2,100 cases of acquired immunodeficiency syndrome (AIDS). These cases had either biopsy-confirmed Kaposi’s sarcoma or a biopsy or culture confirmed life-threatening opportunistic infection, without an identifiable cause of immunosuppression.… Read more
Between July 1, 1979, and March 15, 1981, there were 22 unsolved homicides and two unsolved disappearances of Atlanta children. Using epidemiologic methods, we attempted to identify factors that had put children at an increased risk of homicide. That all victims in this cluster were black, killed away from home, and that asphyxiation was overrepresented suggests that the cluster was discrete.… Read more
Of 2157 patients with the acquired immunodeficiency syndrome (AIDS) whose cases were reported to the Centers for Disease Control by August 22, 1983, 64 (3 per cent) with AIDS and Pneumocystis carinii pneumonia had no recognized risk factors for AIDS.… Read more

Violence is a major cause of morbidity and mortality in the United States. The Center for Health Promotion and Education, the Centers for Disease Control (CDC) has begun to apply epidemiologic techniques to study the problems of child abuse, child homicide, homicide, and suicide.… Read more
Homicide is a major cause of pediatric mortality. National law enforcement data were analyzed to characterize and differentiate neonaticide, infanticide, filicide, and overall child homicide. Results include the following: Neonaticides often involved parents or unidentified perpetrators and occurred proportionately more in rural areas than did other types of child homicide.… Read more
Violence toward children is an acknowledged pediatric problem, but physicians may not be aware that it is a leading cause of pediatric mortality. Therefore, I used homicide data for persons younger than 18 years of age to characterize child homicide.… Read more
Homicide is one of the five leading causes of death for all persons 1-44 years of age. Over half of the homicides occurring in 1979 did not involve the perpetration of another crime. The authors have defined these as primary homicides and suggest that these deaths require the formulation of public health and social services prevention strategies.… Read more
In 1979, over 20,000 people in the United States were victims of homicide, but public health agencies have not yet defined their role in its prevention. Role definition might begin with differentiating various forms of homicide, so the authors used data on all homicides reported by law enforcement agencies for 1976-1979 to determine whether homicides that did not occur during the perpetration of another crime (primary homicides) differ from those that occurred during the perpetration of another crime (secondary homicides).… Read more
Homicide rates for infants dropped suddenly between 1967 and 1969. The abrupt nature of this decline suggested the change was artifactual. Investigation suggests that two classification revisions instituted at this time were causes of this decline: changes in related codes set forth in the Eighth Revision of the International Classification of Diseases, Adapted, and revision of the standard certificate of death in 1968.… Read more
Decisions about the occurrence of child abuse are increasingly difficult to make because concepts of what qualifies as reportable child abuse may be broadening.
We examined this question by comparing 51 fatal child abuse cases occurring in Georgia between July 1975 and December 1979 to non-fatal cases and to the Georgia population.… Read more
From July 1975 through December 1979, the Georgia Department of Protective Services Central Registry recorded population-based data on confirmed, non-confirmable, and ruled-out child abuse reports. We propose that reporting biases are reflected in the differential characteristics of confirmed and ruled-out reports of child abuse.… Read more
Sexual abuse of children is a complex problem that has had, until recently, received only limited recognition and discussion in the pediatric literature. The reasons for this are twofold. First, the magnitude of the problem is unrecognized. Sexual child abuse is grossly underreported, with a true incidence perhaps 10-fold higher than the reported incidence.… Read more
Sexual and physical child abuse are assumed to differ; however, these differences have not been well characterized epidemiologically. Furthermore, despite assumed differences, these types of abuse are often analyzed as one entity. This can have significant effects on assessment of risk and recommendations for intervention.… Read more
