The incidence and prevalence of dermatitis herpetiformis in Utah.
BACKGROUND AND DESIGN: The incidence and prevalence of dermatitis herpetiformis has never been formally evaluated in any area of the United States. Several northern European studies have shown prevalence rates ranging from 1.2 per 100,000 to 39.2 per 100,000. The present study was performed to evaluate the incidence and prevalence of dermatitis herpetiformis in Utah. Information from 240 patients diagnosed with dermatitis herpetiformis was compiled from hospital records throughout Utah, as well as the sole private dermatopathologist in the state, and from the university referral center of the state. Criteria for inclusion in the study were a clinical diagnosis of dermatitis herpetiformis plus granular deposition of IgA in dermal papillae by direct immunofluorescence of uninvolved skin, or histopathologic findings consistent with the disease. Clinical diagnosis and response to dapsone alone was considered insufficient for inclusion in the study. On the basis of these criteria, as well as exclusion of non-Utah residents, 188 of the original 240 patients qualified for the study. RESULTS: The prevalence of dermatitis herpetiformis in Utah in 1987 was 11.2 per 100,000. The mean incidence for the years 1978 through 1987 was 0.98 per 100,000 per year. The mean age at onset of symptoms for male patients was 40.1 years, and that for female patients was 36.2 years. The male-female ratio was 1.44:1. CONCLUSIONS: This represents the first evaluation of the incidence and prevalence of dermatitis herpetiformis in the United States. These results are similar to those of the previous studies, probably because of Utah's largely northern European ancestry. This population base, plus a much smaller than average black and Oriental population, is likely to have produced a higher incidence and prevalence in Utah than would be seen in other areas of the United States.

Cancer incidence in Mormons and non-Mormons in Utah, 1966-1970.
Between 1950 and 1969 cancer mortality in white Utah residents was 22 per cent less than that in the entire United States population. The religion of 72 per cent of the State residents (Mormon) proscribes use of tobacco and alcohol. We therefore analyzed the 10,641 cases of cancer identified in Utah from 1966 to 1970 and compared the incidence found in Utah Mormons, in Utah non-Mormons, and in a national survey. Comparison of Utah Mormons with non-Mormons showed that Mormons had a lower incidence of all cancers associated with cigarette smoking (P less than 0.00001). Mormon females had a low incidence of cancer of the breast (P = 0.008), uterine cervix (P less than 0.00001), and ovary (P = 0.04); Mormon males had a lower incidence of stomach cancers (P = 0.003). These findings addevidence to the association between cigarette smoking and certain cancers, but leave unexplained the significant differences between Mormons and non-Mormons for incidence of cancer of the breast, cervix, prostate and nervous system.

Animal implantation results with the Utah-100 total artificial heart.
The Utah-100 total artificial heart was designed to have increased reliability over the Jarvik-7 total artificial heart, achieve better fit, and minimize device associated thrombus formation, without decreasing the function. The Utah-100 heart was tested in 28 calves and 3 sheep. The smallest animal at the time of implantation weighted 54 kg. Mean survival duration was 78 days (range, 1-331 days), with 14 animals surviving longer than 60 days. Multiple organ function was maintained satisfactorily with the Utah-100 artificial heart, and mean plasma free hemoglobin values in the calves that survived longer than 100 days were less than 10 mg/dl. Hemorrhage was the main cause of death in animals dying within 30 days after implantation (5/13, 38%); infection was another primary cause of death or termination (4/31, 13%). Deaths due to mechanical failure occurred from valve or diaphragm failure in two cases, yielding a 91% reliability at a 90% confidence level for 60 days' support. No animal died because of driver or other technical failure. Utah-100 hearts showed superior antithrombogenicity in the connector and valve-related areas when compared with the results of the Jarvik-7 heart, which was also fabricated and implanted in our laboratory (p less than 0.01). With these test results, the authors anticipate that the Utah-100 heart will be a safe and effective device for interim use as a bridge to heart transplantation.

A mathematical model of aging processes. IV. A multivariate analysis of blood pressure in a Montreal and a Utah population.
Two populations, one Montreal- and one Utah-based, were studied with respect to heart disease risk factors on a cross-sectional basis. The Utah population afforded consistently lower mean blood pressures than the Montreal population, although there was not evidence that the Utah population was less obese, or had a lower pulse rate. Also, in the Utah population, it was found that the proportion of persons with a family history of heart disease did not differ significantly in the hyper- and normo-tensive groups. Fourteen parameters were investigated in the Montreal population, and the analyses indicated that, when other variables are controlled, age, pulse rate, some measure of serum lipid levels, and a family history of heart disease generally assist in the discrimination between the hyper- and normo-tensive groups, but the obesity measurement did not. In that sense, obesity, on its own, may not be considered a risk factor for hypertension.

Low cancer incidence and mortality in Utah.
Utah cancer mortality for the years 1950-1969 and morbidity for the years 1966-1970 are reported. Utah had 18% fewer cases of cancer than expected based on the Third National Cancer Survey, and 24% fewer cancer deaths than expected based on national mortality data. Cancer sites associated with cigarette smoking and alcohol use accounted for nearly half of these differences. Several major sites not strongly associated with smoking showed lower incidence and mortality than expected. These included pancreas, colon, rectum, female breast, uterine cervix and ovary. A marked excess occurrence above expectation was observed for cancer of the lip. Some possible explanations of these findings are discussed, including some of the unique aspects of the Utah population.

Cardiovascular mortality in Mormons and non-Mormons in Utah, 1969--1971.
Cardiovascular mortality in the State of Utah is among the lowest in the United States. The religion of 72% of the state residents (Mormon) proscribes the use of tobacco and alcohol; a large number of Mormons adhere to this proscription. This study analyzed the 6108 cardiovascular disease deaths between 1969--1971 in Utah of members in the Mormon Church. For both sexes, Mormons had 35% less mortality than expected from US rates for ischemic heart disease, while non-Mormons were not significantly different from US whites. These results support the relationship between cigarette smoking and mortality from cardiovascular disease. Mormon men also had lower mortality from hypertensive heart disease and Mormon women from rheumatic heart disease than non-Mormons in Utah.

Parasites of the coyote (Canis latrans) in central Utah.
Seventeen coyotes, Canis latrans, from central Utah were surveyed for parasites. Five species of parasites not reported previously from coyotes in Utah were detected: Filaroides osleri, Physaloptera sp., Spirocerca sp., Ancylostoma caninum, and Cediopsylla simplex. In all, 11 genera of parasites were observed.

Echinococcus granulosus in dogs and sheep in central Utah, 1971-1976.
During 1971 to 1976, a survey was conducted to determine the prevalence of Echinococcus granulosus infection among dogs and sheep in central Utah. For each year, the number of dogs positive for adult tapeworms of the total number examined and the percentage infected were: in 1971, 14 of 51 infected (27.4%); in 1972, 13 of 46 infected (28.3%); in 1973, 7 of 36 infected (19.4%); in 1974, 34 of 244 infected (13.9%); in 1975, 13 of 267 infected (4.9%); and in 1976, 14 of 195 infected (7.2%), or a 6-year total of 95 of 839 infected (av = 11.3%). For each year, the number of sheep positive with hydatid cysts of the total number examined and the percentage infected were: in 1971, 103 of 1,007 infected (10.2%); in 1972, 235 of 1,808 infected (13.0%); in 1973, 242 of 2,003 infected (12.1%); in 1974, 105 of 1,406 infected (7.5%); in 1975, 96 of 1,599 infected (6.0%); and in 1976, 96 of 1,171 infected (8.2%), or a 6-year total of 877 of 8,994 infected (av = 9.8%). These results represent a definite decline in numbers of infected animals and suggest that preventive and control measures advocated in central Utah are being implemented.

Elementary school absences and PM10 pollution in Utah Valley.
This study assessed the association between school absenteeism and respirable particulate pollution (PM10) in Utah Valley for the six school years of 1985 to 1990. Weekly absenteeism data from the Provo School District and daily data from a single elementary school in the Alpine School District were analyzed for kindergarten through sixth grade. PM10 concentrations during the study period averaged approximately 50 micrograms/m3 with the 24-hr maximum equal to 365 micrograms/m3. Absenteeism was regressed on PM10 pollution levels, temperature, snowfall, and variables indicating day of week, month of school year, and days preceding and following holidays and extended weekends. Estimated associations between absenteeism and PM10 pollution in both data sets were positive, statistically significant (P less than 0.01), and robust to different model specifications. PM10 effects persisted for up to 3 or 4 weeks. Regression results from both data sets indicated that an increase in 28-day moving average PM10 equal to 100 micrograms/m3 was associated with an increase in the absence rate equal to approximately two percentage points, or an increase in overall absences equal to approximately 40%. Similar relationships were observed for all grade levels, although the response of absences to air pollution was generally greater for grades 1-3 compared with grades 4-6. Associations between absenteeism and PM10 pollution were observed even for levels below 150 micrograms/m3.

Studies of collagen in bone and dentin matrix of a Columbian mammoth (late Pleistocene) of central Utah.
A Columbian mammoth, Mammuthus columbi, was excavated at an elevation of 9000 feet in Huntington Canyon, Emery County, Utah. Radiocarbon dates on the skeleton indicated death approximately 11,200 years ago. The skeleton was removed from postglacial, Late Quaternary, lake sediments deposited as glacial runoff approximately 9500 years ago. The bones and teeth were especially well preserved in a saturated lake bed. After excavation the bones and teeth were preserved by controlled desiccation, without hardeners, over a period of 9 months. Microradiography, light and electron microscopy, medium and high angle X-ray diffraction, amino acid analysis and cyanogen bromide peptide mapping were undertaken to evaluate the packing, organization, and preservation of collagen in bone and dentin of this mammoth. Microradiography and light microscopy showed that the bone consisted of especially well preserved compact and trabecular bone, and electron microscopy of demineralized bone and tusk showed that the matrix consisted of lamellae of densely packed cylindrical collagen fibrils. Cell remnants with intact nuclei, with or without a nucleolus, as well as variable lengths of plasma membrane were occasionally present on the surface of bony trabecula. Remnants of odontoblast processes were present in some dentin tubules. High and low angle X-ray diffraction demonstrated that the demineralized matrix contained native collagen molecules and amino acid analysis showed that the composition was comparable to that of type I collagen. Cyanogen bromide peptide mapping indicated that the major peptides of type I collagen were present and had the same electrophoretic mobility as that of type I collagen of demineralized Asian elephant bone and rat tail tendon.(ABSTRACT TRUNCATED AT 250 WORDS)

Daily mortality and PM10 pollution in Utah Valley.
The association between daily mortality and respirable particulate pollution (PM10) in Utah County was assessed from April 1985 through December 1989. Poisson regression analysis was used to regress daily death counts on PM10 pollution levels, controlling for variability in the weather. A significant positive association between nonaccidental mortality and PM10 pollution was observed. The strongest association was with 5-d moving average PM10 levels, including the concurrent day and the preceding 4 d. An increase in 5-d moving average PM10 levels, equal to 100 micrograms/m3, was associated with an estimated increase in deaths per day equal to 16%. The association with mortality and PM10 was largest for respiratory disease deaths, next largest for cardiovascular deaths, and smallest for all other deaths. Mean PM10 concentrations during the study period equaled 47 micrograms/m3. The maximum 24-h and 5-d moving average PM10 levels equaled 365 and 297 micrograms/m3, respectively. Relatively low levels of sulfur dioxide, aerosol acidity, and ozone suggested an independent association between mortality and PM10. The relative risk of death increased monotonically with PM10, and the relationship was observed at PM10 levels that were well below the current National Ambient Air Quality Standard of 150 micrograms/m3.

Risk factors for cardiovascular disease predict the development of diabetes among Utah families.
In 1989, we sent a medical follow-up questionnaire to 2,728 members of 98 Utah families originally screened from 1980 to 1983 in the Cardiovascular Genetics Research Clinic. The response rate was 69.9%. Of 1,134 nondiabetic individuals initially age 18 or older who returned the questionnaire, 10 were found to be newly diagnosed with diabetes. The incidence of diabetes was higher among individuals who were found at baseline to have central obesity, lipid abnormalities, especially increased triglyceride levels, and hypertension. Family histories of coronary heart disease and diabetes were not related to the development of diabetes. Our findings that cardiovascular disease risk factors predict the development of diabetes in this relatively young, Caucasian population are consistent with the results of studies from several different populations.

Community aftercare of patients discharged from Utah state hospital: a follow-up study.
To find out whether patients discharged from mental hospitals to the community are following recommended courses of aftercare treatment, the authors, with the assistance of five medical students, studied a sample of patients discharged from Utah State Hospital during 1973 and 1974. The discharge plans of 143 patients admitted from Salt Lake County indicated that 125 of them should have received aftercare services from a community mental health center. A review of CMHC records and interviews with the patients indicated that only 100 actually had contact with a center. Only 43 of the patients were still receiving aftercare services in the summer of 1975.

Home birth in Salt Lake County, Utah.
In Salt Lake County, Utah in 1972 and 1975, 167 women had planned home deliveries. Birth certificate data indicated they did not differ from the total population in age, marital, and socioeconomic status. Eighty-four women were interviewed and reported hostility from health professionals which may have placed them at unnecessary risk.

Hydatid disease screening: Sanpete County, Utah, 1971-1976.
Between 1971 and 1976 approximately 20% (2,265) of the population of Sanpete County, Utah, was screened for hydatid disease (Echinococcus granulosus) by intradermal, indirect hemagglutination, and bentonite flocculation tests. Of 34 persons who had follow-up chest radiographs and radioisotope liver scans, 6 were found to have asymptomatic hepatic cysts. If a participant who had pulmonary cysts and negative screening tests were included, the prevalence of asymptomatic hydatid disease would be 3 per 1,000. During the same period, 82 (148 per 1,000) of 553 dogs successfully purged and examined had E. granulosus infections. Human cyst carriage was associated with dog ownership, particularly of infected dogs or in conjunction with sheep raising as the main livelihood. Combinations of immunodiagnostic tests were more efficacious in identifying cyst carriers than the tests used singly. Limitation of screening to high risk groups (e.g., sheep raisers with dogs) can reduce costs without reducing yield. Optimum management of the cyst carrier awaits further information on the natural history of asymptomatic hydatid disease.

A serologic survey of mule deer and elk in Utah.
Sera from mule deer (Odocoileus hemionus) and elk (Cervus canadensis) in central and northern Utah were tested for the prevalence of antibodies to 11 diseases communicable to man or domestic livestock. Antibodies to Francisella tularensis (at 1:20) were found in 47 of 88 (53.4%) elk and 1 of 89 (1.1%) deer. A screening slide agglutination test for titers to Brucella (at 1:20) showed two reactors in elk but none in deer sera. No positive antibody titers were obtained in tests for anaplasmosis, Colorado tick fever, Rocky Mountain spotted fever, Q-fever, psittacosis, Powassan, western equine encephalitis, St. Louis encephalitis and California encephalitis.

Evidence for gene-environmental interactions in Utah families with hypertension, dyslipidaemia and early coronary heart disease.
1. Among 45,258 Utah families surveyed, about 4% have a strong aggregation of early coronary disease. In detailed clinical evaluation, about 21% of such high risk coronary families were found to have familial dyslipidaemic hypertension (FDH) and about 3% were found to have heterozygous familial hypercholesterolaemia (hFH). 2. Common and potentially modifiable environmental factors seem to play an important role in these high risk families. Non-genetic obesity promotes the expression of FDH. A high fat diet promotes the expression of FH. Cigarette smoking promotes earlier death in all coronary prone families. 3. Practical approaches are suggested for helping coronary prone pedigrees by applying our understanding of genetic and environmental factors that promote earlier coronary disease onset.
