Compared prevalence of infections by HIV-1 and HIV-2 during a 2-year period in suburban and rural areas of Ivory Coast.

The testing for human immune deficiency virus type 2 (HIV-2) antibodies of 794 sera collected in July-August 1985 in the four regions of Korhogo, Bondoukou, Man, and Bouaké in Ivory Coast and the collection and testing for HIV-1 and HIV-2 antibodies of 1,126 sera collected in July-August 1987 in the same regions and age groups showed a remarkable stability in the prevalence of infection by these two retroviruses (0.7 and 0.4% in 1985 vs. 0.9 and 0.2% in 1987, respectively, for HIV-1 and HIV-2) in rural areas. In contrast, the increase in prevalence of both HIV-1 (from 1 to 1.9%) and HIV-2 (from 0.8 to 1.3%) from 1985 to 1987 in the urban population was accompanied by a sharp increase during these 2 years of the number of acquired immune deficiency syndromes in regional hospitals.

ACR accredited suburban mammography center. Three year results.

The results of patients recommended for biopsies were reviewed retrospectively as well as the prevalence and incidence of breast cancer detected during a three-year course, October 1984-October 1987, in an American College of Radiology accredited mammography imaging center. The prevalence of cancer was 26.11 per thousand in 2,681 symptomatic patients and 21.13 per thousand in 1,162 asymptomatic patients. The average annual incidence was 1.9 per thousand women years. The ratio of cancer to benign biopsies was 1:2.13. This is a reasonable and cost-effective result for this free-standing center during the time interval evaluated. To date: sensitivity, asymptomatic .82, symptomatic .96; PPV, asymptomatic .21, symptomatic .42; specificity, asymptomatic 92, symptomatic 96.

A study of asthma in a Dunedin suburban area.

Asthma was reported by 6.2 percent of 2347 inhabitants of a Dunedin residential area. Symptoms occurred within the past two years in 4.2 percent. In this group the majority showed evidence of atopy by skin reactivity and elevation of serum immunoglobulin E. Airways obstruction was detected by spirometry in 62 percent and 56 percent demonstrated increased bronchial reactivity to histamine aerosols. Less than half used bronchodilator aerosols for relief and only 18 per cent were treated with prophylactic disodium cromoglycate.

[Activities of the emergency department of a suburban hospital in 1984].

This is a review of the population coming to the outpatients department along June 1984. Most of the people are coming between noon and midnight. 20% of the patients are driven by ambulance and 59% of them are admitted, while only 23% of the total population and 11% of surgical cases are hospitalized. 56% of the patients are living in the neighbourhood of the hospital and 38% in the other suburbs of Brussels' urban area. Only 26% of the patients are referred by the family physician and 86% of them are admitted, while only 14% are requesting for a specific examination.

[Preliminary studies on the occurrence of Rickettsiae of the spotted fever group in Rhipicephalus sanguineus captured in suburban areas].

In the urban periphery of Rome, two sub-zones could be distinguished, characterized by uncultivated steppeland and by small shacks with large quantities of domestic refuse, respectively. Rhipicephalus sanguineus appeared to be typical of this second sub-zone. R. sanguineus adults and nymphae were captured in different seasonal periods and were checked for the prevalence of rickettsiae of the Spotted Fever (SF) group. Moreover, larvae from hatched eggs, laid by captured R. sanguineus females, were checked for the transovarial transmission of rickettsiae. Ten lots each of three guinea-pigs, seronegative to rickettsiae of the SF group, were inoculated with R. sanguineus extracts, prepared from adults or larvae. Clinical signs of infection, fever and scrotal reaction, could be observed only in one lot of guinea-pigs inoculated with adult parasites. On the other hand, in 8 out of 10 guinea pig lots, antibodies to the soluble antigens of R. conori and R. slovaca were observed by the complement fixation (CF) test. In the remaining two lots only antibodies to R. slovaca were detected. No antibodies to Coxiella burneti could be demonstrated in the same sera.

The incidence of acute rheumatic fever in a suburban area of Los Angeles. A ten-year study.

The incidence of in-hospital cases of acute rheumatic fever in residents of the San Fernando Valley section of Los Angeles (population 1,096,000) from 1971 through 1980 was 0.21 per 100,000 population for all ages and 0.63 per 100,000 for 5 to 17 year olds, both among the lowest ever reported in the world literature. Nevertheless, minority group patients had five times the risk of a white patient for acute rheumatic fever developing and a greater than 20-fold increase in the risk for the development of acute rheumatic fever with carditis. Unexpectedly, a low 30% of cases (8/27) had carditis either alone or with other major criteria, while a high 59% (16/27) had polyarthritis as the only major manifestation. This suggests the possibility of false-positive cases based on polyarthritis as the only major manifestation, and that an incidence of acute rheumatic fever may have been reached that is so low that "background" cases are a significant proportion of all cases.

Myocardial infarction and cerebral infarction in a Danish suburban community.

A comparison was made of 485 cases of cerebral infarction (CI), registered prospectively in Frederiksberg, Copenhagen, with 495 cases of myocardial infarction (AMI), recorded retrospectively in the same population. The overall annual incidence of AMI was 6.5 per 1,000 population for males, 3.8 for females; the rates for CI were 2.4 and 2.5, respectively. The age-incidence curves, particularly those for AMI, were significantly steeper in the females than in the males. Correspondingly, the male predominance in the AMI-group subsided with age. Age-specific incidence-rates rose exponentially with advancing age; for each sex and diagnosis the relationship can thus be expressed as a simple mathematical formula, which may facilitate comparisons of incidence patterns in different communities. Theories explaining the similarities and differences of the age-incidence curves for AMI and CI are discussed.
