Lung cancer in Florida. Risks associated with residence in the central Florida phosphate mining region.

A case-control study that included 25,398 cases of lung cancer among Florida residents, first diagnosed in 1981-1983, was conducted to determine if residence in the central Florida phosphate mining region was associated with an increased risk of lung cancer. A twofold increase in lung cancer risk was observed among male nonsmokers who lived in the study area. Risks were elevated for all major lung cancer cell types, with the highest risks observed for small cell carcinoma of the lung. Among cigarette smokers, a slight, but not statistically significant, additional increase in risk was associated with residence in the study area. Among women, no significant elevations in risk were observed for persons who lived in the study area. The greatest increase in risk among women was for small cell carcinomas, but the elevations were not statistically significant.

Department of Community Dentistry, University of Florida College of Dentistry, Gainesville, Florida.

The oral health status of 454 children and 115 adults from a population of migrant and seasonal farmworkers in Florida was assessed. The prevalence of disease among the children was consistent with that reported for other black children of this age. The migrants had received more dental treatment than the children of seasonal farmworkers; however, the level of care for both groups was strikingly low. The results of this neglect were clearly reflected in the mouths of the adults, most of which were found to be in a very deteriorated state of dental health. A program to cope with these long unmet needs is unrealistic. Efforts should be made to eliminate pain and infection until the cycle of poverty can be broken.

House dust mite allergy in Florida. Mite survey in households of mite-sensitive individuals in Tampa, Florida.

This study evaluated the prevalence of positive house dust mite skin tests in a population of atopic individuals and identified the mite species present in mattress and house dust samples in homes of the Tampa Bay area. Four hundred consecutive individuals were evaluated for respiratory complaints and skin tested with standardized extracts of Dermatophagoides pteronyssinus (Dp) and Dermatophagoides farinae (Df). Two hundred forty individuals (60%) had a positive skin test to the mite extracts. Dust samples were collected in 40 homes of mite-allergic individuals and analyzed by light microscopy. Mite species were found in 53 of the 60 dust samples (20 mattresses and 40 carpets). Mite numbers ranged from 110-6200 mites/g of mattress dust and from 120-5500 mites/g of carpet dust. Eleven different mite species were identified and Blomia tropicalis (Bt), not previously identified in the United States, was found in 30% of the samples. Dp and Df wee the predominant species. These observations suggest that house dust mite allergy is common in the Tampa Bay area and that the house dust mite fauna comprises several mite species besides Dp and Df. Prospective studies in progress are designed to confirm the role of different mite species in house dust mite allergy.

Human infections with Tensaw virus in south Florida: evidence that Tensaw virus subtypes stimulate the production of antibodies reactive with closely related Bunyamwera serogroup viruses.

Maguari virus, a member of the Bunyamwera serogroup (family Bunyaviridae, genus Bunyavirus) has not been isolated north of Trinidad. Anecdotal information from other investigators has indicated the presence of antibody to Maguari virus in human residents of south Florida. We attributed such antibody to either cross-reactivity with Tensaw virus, the only Bunyamwera serogroup virus known in south Florida, or to cross-reactivity to an antigenic subtype or variant of Tensaw virus. Five strains, identified as Tensaw virus when they were isolated from mosquitoes collected in south Florida more than 20 years ago, were retrieved from storage. They were compared by serum dilution-plaque reduction neutralization tests with Bunyamwera serogroup prototypes Tensaw, Maguari, Cache Valley, and Tlacotalpan viruses. The south Florida isolates were shown to be most closely related to prototype Tensaw virus and most distantly related to prototype Maguari virus. One isolate could not be distinguished from prototype Tensaw virus, and the other 4 appeared to be subtypes of prototype Tensaw virus. More than 300 serum samples from humans in south Florida were tested for neutralizing antibody to prototypes Tensaw and Maguari viruses and to 3 of the field isolates. Thirteen had antibody to prototype Tensaw virus only, 19 to prototype Maguari virus only, and 39 to both. Antibody to all but 6 of these 71 was attributed to infection with Tensaw virus, to a subtype of Tensaw virus, or to travel or birth outside the United States. It is likely that those with antibody to Maguari virus only had been infected with yet another subtype of Tensaw virus, although another, undiscovered, Bunyamwera serogroup virus may exist in south Florida.

The incidence of pediatric cancer in Florida, 1981 to 1986.

Incidence rates for pediatric (ages, 0 to 14 years) cancer in the state of Florida were produced for the period 1981 to 1986 and compared with national data to investigate variations in pediatric cancer incidence. Overall, Florida had an incidence rate of 12.77 per 100,000; this was not significantly higher than expected based on national rates (standardized incidence ratio, 1.0; 95% confidence interval, 0.9 to 1.0). Compared with national rates, whites residing in Florida had an increased rate of acute lymphocytic leukemia and decreased rate for soft tissue sarcomas (other than rhabdomyosarcoma), "other leukemias," and "other" cancers. Nonwhites residing in Florida had increased rates for soft tissue sarcomas (other than rhabdomyosarcoma) and decreased rates of "other" cancers. Boys in Florida had increased rates for retinoblastoma and acute lymphocytic leukemia and decreased rates for "other leukemias" and "other" cancers. Rates for girls were decreased for neuroblastoma and "other leukemias."

Genetics of house flies. Variability studies with North Dakota, Texas, and Florida populations.

Genetic data were used to compare the structure of native house fly populations collected in North Dakota, Texas, and Florida. Recombination studies with mutant markers on chromosomes 3 and 4 indicated a lack of inversion polymorphism among the three populations in those areas of the genetic map studied. Significant differences were observed among flies from the three regions with regard to the frequency of 1) females that produced only male progeny, and 2) male-determining 3rd chromosomes (IIIm chromosomes). However, the North Dakota and Texas flies were more similar to each other than to the Florida flies since populations from the two former areas possessed a low frequency of both male-producing females and IIIm chromosomes; in contrast, the Florida population was void of females that produced males only and a high percentage if not all Florida males appeared to possess the IIIm male-determining mechanism. Tests for recessive lethal 3rd chromosomes showed that there was no significant difference in the frequency of lethal factors recovered from the North Dakota and Texas flies; the presence of IIIm chromosomes in Florida males precluded the recovery of lethal factors from this population by the method employed. The data suggest that house fly strains to be employed in genetic control programs should 1) originate from target control areas to avoid possible behavioral differences existing among flies from different locales, 2) be initiated with as many flies as possible to provide a background for the maintenance of variability, and 3) be renewed periodically with field-collected material since the genotype may be capable of rapid reorganization in response to laboratory selection pressures.

Lightning-related mortality and morbidity in Florida.

Cases of lightning-related deaths and injuries that occurred in Florida in 1978-87 were reviewed to determine the factors involved, to quantify the morbidity and mortality related to lightning strikes, and to describe epidemiologically the injuries and circumstances involved. Statewide information on deaths was obtained from death certificates, autopsy reports, and investigative reports. Information about morbidity was obtained from the Florida Hospital Cost Containment Board data base and the National Climatic Data Center data base for all Florida counties, as well as from hospitals in selected counties. Lightning-related deaths totaled 101 in Florida during the period 1978-87, an annual average of 10.1. Eight percent of the victims were from other States. The overall yearly death rate for State residents was 0.09 per 100,000 population, with the highest rate being that for men aged 15-19 years, 0.38 per 100,000. Thirteen percent of victims were females. The ratio of lightning-related injuries to deaths in Florida was estimated at about four to one. Thirty percent of all deaths were occupationally related. The first strikes of lightning from a thunderstorm may be the most dangerous, not in terms of impact, but because of the element of surprise. During thunderstorms, people may seek shelter under isolated trees because they believe erroneously that a tree offers protection from lightning, or perhaps because their top priority is to escape from rain rather than lightning. People may not seek adequate shelter during thunderstorms because they do not know the dangers of remaining outdoors or their judgment is impaired by drugs or alcohol.

Needlestick injuries and hepatitis B immunization in Florida paramedics: a statewide survey.

STUDY OBJECTIVES: To determine the incidence of needlestick injury among paramedics working in Florida during 1987, to describe the circumstances surrounding such injuries, and to assess the hepatitis B vaccination status of this group. DESIGN: Survey of a systematic random sample of paramedics using a self-administered questionnaire. SETTING: Florida. TYPE OF PARTICIPANTS: Paramedics. MAIN RESULTS: A completed questionnaire was returned by 300 of 500 paramedics (60%) who received the mailed questionnaire. Sixty-nine paramedics (23%) reported a total of 110 needlestick injuries. More than one third of injuries occurred in conjunction with recapping needles. Almost 62% of reported injuries could have been prevented had proper needle disposal technique been used. Sixty-two percent of paramedics reported having had at least one dose of the hepatitis B vaccine. Sixty-five percent of the unvaccinated paramedics said they would take the hepatitis B vaccine if it was offered free. CONCLUSION: The majority of needlestick injuries among paramedics in Florida could be prevented with proper needle disposal. Offering the hepatitis B vaccine at no charge to paramedics in Florida could increase the vaccination rate substantially.

An examination of loneliness among elderly Canadian seasonal residents in Florida.

As part of a larger study focusing on different facets of the lives of 2,731 older Canadians who seasonally reside in Florida, we investigated primarily the extent of family and friendship contacts and the loneliness expressed by these older Canadians. The data were collected using a questionnaire that was distributed and returned by mail. The sample was taken from the subscription list of a newspaper in Florida that was a subsidiary of a large Canadian newspaper. The results show a population that was relatively young, married, in generally good health, and with rather extensive contacts with family and friends while residing in Florida. Nevertheless, more than a fifth indicated they were at least somewhat lonely. Results, using discriminate function analysis, showed that those more lonely were younger, female, less educated, not married, in poorer physical health, had fewer Florida friends, and had more children who lived near them in Canada, but fewer children who lived near them in the United States. Implications of the results are discussed.

Effects of breed group by location interaction on crossbred cattle in Nebraska and Florida.

Data on 2,744 calves produced in Clay Center, Nebraska and Brooksville, Florida were used to evaluate the importance of genotype x location interactions on the reproductive and maternal performance of eight breed groups of F1 crossbred cows. A total of 648 F1 crossbred cows included Bos taurus x Bos taurus (Bt x Bt) crosses: Hereford x Angus reciprocal crossbreds (HA and AH), Pinzgauer x Angus (PA), Pinzgauer x Hereford (PH); and Bos indicus x Bos taurus (Bi x Bt) crosses: Brahman x Angus (BA), Brahman x Hereford (BH), Sahiwal x Angus (SA) and Sahiwal x Hereford (SH). The first calf crop was sired by Red Poll bulls. All remaining calf crops were sired by Simmental bulls. Although the pregnancy rate was 9% higher in Nebraska, the rate of unassisted calvings and calf survival rate were both 4.6% lower in Nebraska. Calf birth and weaning weights were 8.0 and 15.6 kg heavier in Nebraska than in Florida. Bi x Bt dams exceeded (P less than .001) Bt x Bt crossbred dams for all traits except age of calf at weaning and calf-survival rates (P greater than .10). Birth weights of calves from Bi x Bt crossbred dams were 3.4 kg lighter than those from the Bt x Bt crossbred dams. The interaction of location with the breed group comparison of Bi x Bt vs Bt x Bt crossbred dams was significant for pregnancy rate, calf age at weaning, rate of unassisted calving and all weight traits. Adjusted weaning weights of calves from HA, AH, PA, PH, BA, BH, SA and SH cows were as follows: HA, 194 and 222; AH, 202 and 230; PA, 213 and 242; PH, 217 and 245; BA, 251 and 254; BH, 252 and 254; SA, 236 and 238; and SH, 238 and 243 kg, respectively, in Florida and Nebraska. Bos indicus-sired cows (BA, BH, SA and SH) weaned essentially equal-weight calves at both locations, whereas calves from Bt x Bt crossbred cows (HA, AH, PA, PH) were about 28 kg lighter in Florida.
