Assessment of physicians' information needs in five Texas counties.

In 1990, a questionnaire was mailed to all physicians in four counties in the lower Rio Grande Valley of Texas and to a random sample of physicians in Bexar County, Texas (San Antonio). Two hundred and eighty of 573 Valley physicians (48.9%) and 162 of 273 Bexar County physicians (59.3%) responded to the survey, for an overall response rate of 52.2%. The two groups were compared primarily to determine differences between physicians who have access to established medical libraries and physicians who practice in remote areas without local access to medical information. Demographic variables, professional practice characteristics, and patient characteristics were compared. Information resource use, particularly reasons for use and non-use of MEDLINE, was explored. Questions also were asked about the availability of various types of information technology. The results indicated that differences in the health care profile did not affect the information usage of the physicians but that differences did exist between the two groups in the use of MEDLINE and libraries. There was no statistically significant difference in either group's rating of experience with using databases, with more than 40% in each group rating themselves as not at all experienced.

Patterns of infant mortality in relation to birth weight, gestational and maternal age, parity, and prenatal care in Texas' triethnic population, 1984 through 1986.

Neonatal, postneonatal, and infant mortality rates were determined in Texas' triethnic populations from 1984 through 1986 with relation to gestational age, birth weight, maternal age, parity, and prenatal care. All mortality rates were increased in the black population. Preterm birth and low birth weight were both strong predictors of mortality. The neonatal mortality rate of preterm black infants was actually lower than those of the other ethnic groups, but the increased proportion of black pregnancies that resulted in preterm and low-birth-weight births, together with their elevated postneonatal mortality rates, produced an infant mortality rate that was twice as high in black as in Anglo and Hispanic infants. The infant mortality rate was highest in infants born to mothers younger than 18 years, of high multiparity, and with inadequate or no prenatal care. Recognition of these associations should enable improved planning of care for all Texas women and their infants.

Excess leukemia and multiple myeloma in a mining county in northeast Texas.

From 1950 to 1979, cancer mortality rates in Titus County, Texas, increased with a significant excess of deaths from leukemia, lymphoma, brain and liver cancers, and melanoma. County residents requested this study to verify the apparent excess of cancer. Newly diagnosed cases of cancer among white residents from 1977 to 1984 were ascertained from the Texas Cancer Registry, hospital records, and death certificates. Direct and indirect methods were used to calculate incidence rates and standardized incidence ratios (SIR). We identified 663 cancers for 148,470 person-years of observation. No overall excess of cancer was found. However, we found a significant excess of leukemia (SIR = 2.53, 95% confidence interval [CI] = 1.86, 3.30) and multiple myeloma (SIR = 1.87, 95% CI = 1.02, 3.14). The reasons for the increased SIRs are unknown. However, the excess of cancers in this mining community may be relevant to the ongoing debate on the health effects of the disposal of combustion wastes from mining and fossil fuel and on the need for stricter regulations. Other potential risk factors include the presence of petrochemical and poultry industries. regulations. Other potential risk factors include the presence of petrochemical and poultry industries.

Patterns of birth weight in relation to gestational age, maternal age, parity, and prenatal care in Texas' triethnic population, 1984 through 1986.

This study investigated the distribution of birth weights in Texas' triethnic populations for the years 1984 through 1986 (more than 900,000 births) with regard to gestational age, maternal age, parity, and visits for prenatal care. African-American infants had a systematic tendency to be born earlier and smaller than Anglo and Hispanic infants. Among the maternal age categories, mothers younger than 18 years had the highest rates of preterm birth (less than 37 completed weeks), very low birth weight (less than 1500 g), and low birth weight (less than 2500 g). High multiparity and inadequate visits for prenatal care were associated with increased rates for the same adverse pregnancy outcomes, and the risks were always much higher in African-American than in Anglo and Hispanic women of the same age, parity, and prenatal care categories. The predictive values of these associations for individual pregnancies were limited, but their recognition may improve the planning of prenatal care for Texas women and of the anticipatory care for their infants.

Distribution, abundance and bionomics of Aedes albopictus in southern Texas.

A survey was conducted for Aedes albopictus in southern Texas during the summer of 1992. Thirty-five new country records were added to the distribution of this imported mosquito in Texas. Aedes albopictus was widely distributed throughout the ecological regions in the survey area, but its abundance decreased in counties adjacent to the Rio Grande River. However, these counties had high densities of Aedes aegypti.

Hispanic elders in Texas: implications for health care.

Hispanic elders are a large, rapidly growing subgroup of the Hispanic population in Texas. This population continues to suffer from a high incidence of non-insulin-dependent diabetes mellitus, with similar or lower rates of cardiovascular disease than non-Hispanic whites have. Barriers that may modify potentially effective diagnostic or appropriate treatment plans include communication problems, access issues, and use of informal health-care services. Knowledge and attention to these issues may improve compliance and decrease morbidity of this cohort. This article summarizes important information affecting the health of Hispanic elders in Texas and alerts practitioners to issues that may affect the care of their older Hispanic patients.

Use of clozapine in Texas state mental health facilities.

Clozapine-use patterns in facilities operated by the Texas Department of Mental Health and Mental Retardation are reported. Data collected by manual and automated tracking systems from January 1990 through July 1992 were analyzed to determine patient demographics, the number of patients started on clozapine and the number who stopped taking the drug, the reasons for discontinuation, and other variables. Of 852 clozapine recipients still in the departmental system by the end of the study period, 134 (16%) had discontinued the drug by that date. There were no significant differences in gender, age, or race between the patients who discontinued the therapy and those who did not. Almost one fourth of the patients who discontinued clozapine therapy did so within the first month, and more than 90% did so within the first year. The most common reasons for discontinuing the medication were lack of clinical response, patient refusal or request, and adverse effects, including agranulocytosis. More women than men discontinued the drug because of adverse effects. Although relatively few patients discontinued clozapine during the study period, many had only recently begun taking the drug, and some of these may discontinue it in the near future. Of 852 clozapine-treated patients served by the Texas Department of Mental Health and Mental Retardation between January 1990 and July 1992, 16% discontinued the therapy. One fourth of these did so within the first month of treatment.

Acute myocardial infarction and coronary heart disease mortality among Mexican Americans and non-Hispanic whites in Texas, 1980 through 1989.

We calculated acute myocardial infarction and chronic coronary heart disease mortality rates for Mexican Americans and non-Hispanic whites in Texas for the 10-year period from 1980 through 1989 in an examination of ethnicity-related differences in death rates and trends according to vital statistics for the state of Texas. During the study period, acute myocardial infarction mortality decreased significantly in all four sex-ethnic groups, between 5.1% and 7.4% per year. Chronic coronary heart disease mortality rates decreased less, but significantly, for women in both ethnic groups, decreasing 3.4% and 1.8% per year for Mexican-American and non-Hispanic white women, respectively. We found no significant trend of changes in chronic coronary heart disease mortality rate among men in either ethnic group. For both acute myocardial infarction and chronic coronary heart disease mortality, rates were significantly lower among Mexican-American men than among non-Hispanic white men. Age-adjusted rate ratios for Mexican-American men in relation to non-Hispanic white men were 0.78 (95% CI: 0.65-0.93) and 0.75 (0.65-0.86) for acute myocardial infarction and chronic coronary heart disease mortality, respectively. No significant ethnicity-related mortality difference was seen among women. This previously observed interaction of ethnicity and sex in relation to coronary heart disease mortality remains unexplained. Despite apparently adverse cardiovascular risk factor profiles, Mexican Americans have acute myocardial infarction and chronic coronary heart disease mortality rates equal to or lower than their non-Hispanic white counterparts on the basis of death certificate data. This paradox deserves further attention.

A comparative study of genetic variation at five VNTR loci in three ethnic groups of Houston, Texas.

Following the technique of Southern blot restriction fragment length polymorphisms (RFLP) analysis, we generated a database of DNA profiles at five Variable Number of Tandem Repeats loci (D1S7, D2S44, D4S139, D10S28, and D17S79) for 669 individuals of three major ethnic populations (Caucasians, Blacks, and Hispanics) of Houston, Texas. Analysis of fragment sizes at these loci within each sample, as well as their fixed-bin analyses, reveal that the assumptions of independence of allelic occurrences within and between loci are valid for this database. Fixed-bin allele frequency tables, therefore, are the best descriptors of this database for conservative forensic calculations. Finally, we demonstrate that this regional database from Houston, Texas, does not yield any meaningfully different forensic inference than the one obtained from the National database of the respective ethnic groups.

Adverse events associated with ephedrine-containing products--Texas, December 1993-September 1995.

During December 1993-September 1995, the Bureau of Food and Drug Safety, Texas Department of Health (TDH), received approximately 500 reports of adverse events in persons who consumed dietary supplement products containing ephedrine and associated alkaloids (pseudoephedrine, norephedrine, and N-methyl ephedrine). This total included reports by individuals and reports identified by the Bureau of Epidemiology, TDH, in a review of records from the six centers of the Texas Poison Center Network. Reported adverse events ranged in severity from tremor and headache to death in eight ephedrine users and included reports of stroke, myocardial infarction, chest pain, seizures, insomnia, nausea and vomiting, fatigue, and dizziness. Seven of the eight reported fatalities were attributed to myocardial infarction or cerebrovascular accident. This report describes three patients in which the recommended dosage for the dietary supplements reportedly was not exceeded, summarizes results from ongoing investigations, and underscores the potential health risks associated with the use of products containing ephedrine.

Acute pesticide poisoning associated with use of a sulfotepp fumigant in a greenhouse--Texas, 1995.

Pesticide fumigants that eradicate pests but do not damage flowers or foliage can be used to protect market-ready florals. During November 1995, a pesticide applicator worker in Texas became ill during fumigation despite wearing the personal protective equipment (PPE) recommended on the fumigant product label. This report summarizes the results of the case investigation by the Texas Department of Health (TDH) and CDC's National Institute for Occupational Safety and Health (NIOSH) and a survey of growers about pesticide use. The findings indicate that the recommended PPE may be inadequate to protect workers using sulfotepp fumigants from pesticide poisoning.

Progress towards the year 2000: assessing the health status of minorities in Texas.

In 1991, the Centers for Disease Control and Prevention released a consensus set of 18 health status indicators to help communities assess their general health status and focus local, state, and national efforts on tracking the year 2000 objectives. States and local communities were encouraged also to analyze the indicators for each major racial and ethnic population in their jurisdictions. This article presents an update of trends in Texas for the health status indicators for the total population, along with comparisons by race and Hispanic origin for the most recent data. Analysis of these data reveals that the health status for the total population is improving as we approach the year 2000. Yet despite these overall gains, significant disparities exist between the total population and the racial and ethnic minorities in Texas. Further efforts are needed to reduce these health disparities.

Raw shellfish consumption and warning labels: results from the 1993 Texas Behavioral Risk Factor Surveillance System (BRFSS) survey.

We used the 1993 Texas Behavioral Risk Factor Surveillance System survey to assess the prevalence of raw shellfish consumption and to find the demographic and behavioral characteristics of raw shellfish consumers. We studied the general impact of warning labels reported by survey respondents. Data were analyzed using univariate and multiple logistic regression methods. Fourteen percent of the Texas surveyed reported consuming raw shellfish. Respondents with incomes greater than or equal to $25,000 and with education beyond high school were more likely to report consuming raw shellfish than were those with incomes less than $25,000 and with high school diplomas or less. Respondents at risk for acute and chronic drinking, driving while intoxicated, and driving without a seat belt were more likely than those not at risk of these behaviors to report consumption of raw shellfish. We did not find a significant difference between eaters and noneaters of raw shellfish regarding the impact of warning labels: however, among eaters of raw shellfish, older respondents were more likely than younger respondents to report that warning labels had no effect on them.

Gamma hydroxy butyrate use--New York and Texas, 1995-1996.

Gamma hydroxy butyrate (GHB) is a central nervous system depressant approved as an anaesthetic in some countries; however, with the exception of investigational research, it is not approved for any use in the United States. Primary groups using GHB include party and nightclub attendees and bodybuilders. In addition, GHB is one of several agents characterized as a "date rape" drug. During August 1995-September 1996, poison control centers in New York and Texas received reports of 69 acute poisonings and one death attributed to ingestion of GHB. This report describes two cases and summarizes the investigations of GHB use in Texas and New York. The findings of these investigations underscore the health hazards associated with use of GHB.

Heat-related deaths -- Dallas, Wichita, and Cooke counties, Texas, and United States, 1996.

During July 2-8, 1996, high maximum daily temperatures in Dallas County, Texas, ranged from 101 F (38.3 C) to 106 F (41.1 C), and high maximum daily heat indexes (a measure of the effect of combined elements [e.g., heat and humidity] on the body) ranged from 105 F (40.6 C) to 112 F (44.4 C). Although guidelines for issuing heat advisories or warnings vary by geographic location and climate, the National Weather Service generally suggests issuing a heat advisory when a daytime heat index reaches > or =105 F (> or =40.6 C), and a night time minimum ambient temperature of 80 F (26.7 C) persists for at least 48 hours. In Dallas County, the criterion used by the medical examiner's (ME's) office to designate a heat wave is > or =3 consecutive days of temperatures > or =100 F (37.8 C). This report describes four cases of heat-related death in Dallas, Wichita, and Cooke counties, Texas, in 1996; summarizes risk factors for this problem; and reviews measures to prevent heat-related morbidity and mortality. The findings in this report indicate that, although a large proportion of heat-related deaths occur during the summer and during heat waves, such deaths occur year-round.

Searching for preventable causes of infant mortality in Texas.

Texas' health objectives include reducing the infant mortality rate from 8.1 per 1000 live births in 1990 to no more than 7 per 1000 by the year 2000. To help target potentially preventable causes of infant mortality, we examined the underlying cause of each of the 2545 infant deaths that occurred in Texas during 1990. Potential existed for primary prevention of the underlying cause of at least some of 778 infant deaths and for secondary prevention by treating the underlying causes of 1127. The following appear to be the most promising targets and strategies for prevention: causes of neonatal mortality by improving the clinical care of high-risk newborns; sudden infant death syndrome by having infants sleep in the supine position; respiratory complications of preterm birth by preventive and therapeutic surfactant; death from bacterial infections by optimal antibiotic therapy; injuries and accidents by optimal parental supervision; preterm birth and adverse pregnancy outcomes by optimal prenatal, obstetric, and neonatal care; and neural tube defects by adequate paraconceptual folic acid.
