Update: mercury poisoning associated with beauty cream--Arizona, California, New Mexico, and Texas, 1996.

During September 1995-May 1996, the Texas Department of Health (TDH), the New Mexico Department of Health (NMDH), and the San Diego County (California) Health Department investigated three cases of mercury poisoning associated with the use of a mercury-containing beauty cream produced in Mexico. The ongoing investigation has found this product in shops and flea markets in the United States located near the U.S.-Mexico border, and a U.S. distributor has been identified in Los Angeles. The cream, marketed as "Crema de Belleza--Manning" for skin cleansing and prevention of acne, listed "calomel" (mercurous chloride [Hg2Cl2]) as an ingredient and contained 6% to 10% mercury by weight. This report presents findings of a continuing investigation by these health departments, the Arizona Dept of Health Services (ADHS), California State Department of Health Services (CSDHS), the Food and Drug Administration (FDA), and CDC.

Histopathology of lung cancer in New Mexico, 1970-72 and 1980-81.

In conjunction with a population-based case-control study of lung cancer in New Mexico, the histopathology of cases diagnosed during 1980 and 1981 and during 1970-72 was reviewed. Adequate histologic or cytologic material was obtained for 725 cases, with 308 during 1970-72 and 417 during 1980-81. The light microscopic histologic type was classified on the basis of review by 2 pathologists. No significant differences were found in the histologic-type distributions in Hispanics and non-Hispanic whites. In males, the distributions of histologic types were similar in the two time periods, but in non-Hispanic white women the proportion of adenocarcinoma declined during 1980-81 as the proportion of small cell carcinoma increased. The panel classification was compared with that recorded by the New Mexico Tumor Registry. Overall agreement was 52.1% for 1970-72 and increased to 65.2% for 1980-81. The discrepancies between the two classifications were largest for the categories of large cell undifferentiated carcinoma and "other malignancy."

Ethnic variation in prostate cancer survival in New Mexico.

Prostate cancer survival varies markedly by ethnicity. American Indians and blacks have the lowest 5-year relative survival among ethnic groups in the U.S. In New Mexico, relative survival for prostate cancer is lower for ethnic minority groups than for non-Hispanic whites. To examine factors underlying ethnic differences in prostate cancer survival in New Mexico, we analyzed Surveillance, Epidemiology, and End Results Program data collected by the New Mexico Tumor Registry from 1983 to 1992. Unadjusted relative risk (RR) of death after prostate cancer diagnosis was greater for Hispanics [RR = 1.1; 95% confidence interval (CI), 1.0, 1.2], American Indians (RR = 1.4; 95% CI, 1.2, 1.5), and blacks (RR = 1.5; 95% CI, 1.2, 1.7) than for non-Hispanic whites. After adjusting for age, stage, histological grade, year of diagnosis, and initial treatment, the risk for Hispanics (RR = 1.0; 95% CI, 0.9, 1.1), American Indians (RR = 1.0; 95% CI, 0.9, 1.1), and non-Hispanic whites was comparable. Although based on small numbers, adjusted risk ratios among blacks remained elevated (RR = 1.2; 95% CI, 0.9, 1.6), due in part to lower survival during the first 12 months after diagnosis (RR = 2.0; 95% CI, 1.2, 3.3) and poorer survival following radical prostatectomy (RR = 4.2; 95% CI, 1.3, 13). These findings suggest that poorer survival for Hispanics and American Indians may be explained by delayed detection and differences in treatment.

Immunization coverage and Medicaid managed care in New Mexico: a multimethod assessment.

BACKGROUND: We wanted to examine the association between Medicaid managed care (MMC) and changing immunization coverage in New Mexico, a predominantly rural, poor, and multiethnic state. METHODS: As part of a multimethod assessment of MMC, we studied trends in quantitative data from the National Immunization Survey (NIS) using temporal plots, Fisher's exact test, and the Cochran-Armitage trend test. To help explain changes in immunization rates in relation to MMC, we analyzed qualitative data gathered through ethnographic observations at safety net institutions: income support (welfare) offices, community health centers, hospital emergency departments, private physicians' offices, mental health institutions, managed care organizations, and agencies of state government. RESULTS: Immunization coverage decreased significantly after implementation of MMC, from 80% in 1996 to 73% in 2001 for the 4:3:1 vaccination series (Fisher's exact test, P = .031). New Mexico dropped in rank among states from 30th for this vaccination series in 1996 to 50th in 2001. A significant decreasing trend (Cochran-Armitage P = .025) in coverage occurred between 1996 and 2001. Findings from the ethnographic study revealed conditions that might have contributed to decreased immunization coverage: (1) reduced funding for immunizations at public health clinics, and difficulties in gaining access to MMC providers; (2) informal referrals from managed care organizations and contracting physicians to community health centers and state-run public health clinics; and (3) increased workloads and delays at community health centers, linked partly to these informal referrals for immunizations. CONCLUSIONS: Medicaid reform in New Mexico did not improve immunization coverage, which declined significantly to among the lowest in the nation. Reduced funding for public health clinics and informal referrals may have contributed to this decline. These observations show how unanticipated and adverse consequences can result from policy interventions in complex insurance systems.

Factors predicting cesarean delivery for American Indian women in New Mexico.

BACKGROUND: American Indian women have one of the lowest cesarean delivery rates among all ethnic groups evaluated in the United States. Our objective was to identify risk factors for cesarean delivery among American Indian women in New Mexico. METHODS: Live birth certificate data (1994) from the New Mexico Bureau of Vital Records and Health statistics were used to compare American Indian women who had a cesarean delivery with those who had a vaginal delivery. We examined demographic, prenatal, and intrapartum factors to determine risk factors for cesarean delivery. RESULTS: In 1994 American Indian women in New Mexico had a cesarean delivery rate of 12 percent. Risk factors for cesarean delivery included age equal to or over 35 years (OR = 1.8, 1.3-2.5) and nulliparity (OR = 1.9, 1.5-2.5). Obstetric risk factors included prematurity (OR = 2.3, 1.5-3.6), low birthweight (OR = 2.6, 1.7-4.2), diabetes (OR = 1.7, 1.1-2.5), pregnancy-induced hypertension (OR = 2.6, 1.8-3.8), and labor and delivery complications (OR = 9.5, 7.5-12.1). Age less than 20 years was negatively associated with cesarean delivery (OR = 0.5, 0.3-0.7). CONCLUSION: American Indian women have risk factors for cesarean delivery that are similar to those reported in other populations. Future prospective research evaluating intrapartum management may help identify reasons for the low cesarean birth rate.

The 2002 psychologist prescribing law in New Mexico: the psychiatrists' perspective.

In March 2002 New Mexico passed the first state statute permitting the development of a process leading to prescriptive authority for doctoral level psychologists who obtain requisite training and certification. This article reviews the background of these events, the political processes by which this expanded scope of practice for psychologists evolved, the current state of regulatory discussions regarding this statute, forecasts of the practical impact of this legislation on practitioner patterns, and prospects for the future.

A new Eimeria species (Apicomplexa: Eimeriidae) infecting Onychomys species (Rodentia: Muridae) in New Mexico and Arizona.

Fecal samples from 3 species of Onychomys (Rodentia: Muridae) captured in New Mexico and Arizona were examined for coccidia. Six of the 59 (10%) were infected with a new species of Eimeria. Sporulated oocysts (n = 105) of this new species are subspheroidal, 17.4 x 16.1 (14-21 x 13-19) microm, with ellipsoidal sporocysts 10.4 x 5.7 (9-12 x 5-8) microm. This species occurred in 3 of 24 (13%) Onychomys arenicola, 2 of 31 (6%) Onychomys leucogaster from New Mexico, and 1 of 4 (25%) Onychomys torridus from Arizona. Isolates recovered from O. leucogaster and O. torridus were inoculated into O. leucogaster (n = 5) and produced infections with a prepatent period of 7 days and a patent period of 7-23 days.

Elaeophorosis in bighorn sheep in New Mexico.

Two bighorn sheep (Ovis canadensis) in New Mexico (USA) were found to be naturally infected with Elaeophora schneideri. An adult ram examined in 1997 in the Fra Cristobal Mountains had 26 nematodes in the carotid and iliac arteries, and microfilariae were present in the skin, nasal mucosa, brain, and lungs. This ram was markedly debilitated prior to euthanasia and extensive crusty, scabby lesions were observed on its head. In 1998, a yearling ewe found dead adjacent to Watson Mountain near the Gila Wilderness area was found to have 13 nematodes present in its heart. This is the first report of E. schneideri in bighorn sheep, and we suggest that bighorn sheep are susceptible to E. schneideri infection wherever they coexist with mule deer (Odocoileus hemionus hemionus) and appropriate tabanid vectors.

Venom characteristics as an indicator of hybridization between Crotalus viridis viridis and Crotalus scutulatus scutulatus in New Mexico.

One hundred and thirteen venoms from 46 populations of Crotalus viridis viridis were screened by immunodiffusion for protein toxins antigenically similar to the phospholipase A2 (PLA) toxin 'Mojave toxin', using a polyclonal antibody to it's basic PLA subunit. Venom i.p. LD50 values in mice were recorded from 22 of the 46 populations. The venoms of three of 14 specimens from southwest (S.W.) New Mexico and one specimen from northern Arizona were immunologically positive by the immunodiffusion tests and produced low LD50 values (0.38-0.65 mg/kg) compared to all immunologically negative venoms (0.9-5.5 mg/kg). These four specimens were morphologically typical for C. v. viridis and their venoms were the only samples of 15 southern New Mexico specimens examined by reverse phase HPLC to exhibit peaks corresponding to the acidic and basic subunits of Mojave toxin. Alkaline polyacrylamide gel electrophoresis (PAGE) analysis of the recombined subunit peaks from the C.v. viridis venom from the S.W. New Mexico specimens showed more similarity to Mojave toxin from C.s. scutulatus venom than to similar toxins in C.v. concolor venom. The combined results of the immunodiffusion, lethal toxicity tests, HPLC profiles and PAGE analysis strongly suggest that the venoms of the three New Mexico specimens contain Mojave toxin(s), as a result of some previous hybridization with C.s. scutulatus. The northern Arizona specimen likely contains 'concolor toxin' through integration with C.v. concolor in its' genetic background.

New Mexico's 1998 drive-up liquor window closure. Study II: economic impact on owners.

AIMS: This study examined the economic impact of the New Mexico legislative action closing drive-up liquor windows on the retail establishments that operated them. DESIGN: A telephone survey was conducted 20 months after the closure seeking information and owners' opinions about how their outlets had changed since the closure and how this affected their business. In addition, 2 years of aggregated pre- and post-closure total gross receipts revenues were obtained from the New Mexico Taxation and Revenue Department, with convenience stores as a comparison group. FINDINGS: Interviews were completed for 149 of 220 establishments. Over one-quarter of former drive-up liquor windows (28%) had been converted to 'step-in' sales, defined as an outside door where customers can stop and enter the premises while their car is running. Almost two-thirds (61%) of owners reported decreased annual gross revenues following closure, with a reported average 15% reduction in alcohol sales. This is consistent with findings of decreased gross receipts for operators of non-urban, but not urban, drive-up liquor windows compared to convenience store gross receipts. Almost three-quarters (72%) of those surveyed would re-open the drive-up window if the law were rescinded. CONCLUSION: Over one-quarter of the drive-up owners converted to step-in alcohol sales that still allow a form of drive-up liquor sales. Despite this, the forced closure of New Mexico's drive-up liquor windows negatively impacted total sales and liquor sales revenues of establishments that operated them.

Cigarette smoking and lung cancer in 'Hispanic' whites and other whites in New Mexico.

A population-based case-control study of lung cancer was performed in New Mexico to explain the differing patterns of lung cancer occurrence in the state's "Hispanic" Whites and other Whites. From 1980 through 1982, interviews were completed with 521 cases and 769 controls. In the male controls, the prevalence of current and previous cigarette usage was similar in the two ethnic groups, but Hispanics smoked fewer cigarettes daily. In the female controls, a lower percentage of Hispanics had ever smoked and their usual consumption was less than that of other White women. Older Hispanic female smokers had used hand-rolled cigarettes for an average of 8.8 years, whereas other White women of the same age had used this type for less than one-half year. Both stratified and multiple logistic analysis showed comparable risks of lung cancer in Hispanic White and other White smokers. There was no evidence of interaction between ethnicity and cigarette smoking. These analyses imply that the differences in lung cancer incidence between New Mexico's Hispanic Whites and other Whites are largely explained by the patterns of cigarette smoking of these two groups.

Cigarette use among Hispanic and non-Hispanic white school children, Albuquerque, New Mexico.

We conducted a survey of cigarette usage among Hispanic and non-Hispanic White school children in Albuquerque, New Mexico. The distributions of current, experimental, and never smokers were similar in the two groups. Among smokers, the average weekly cigarette consumption was 19 for Hispanic White males, 14 for non-Hispanic White males, 16 for non-Hispanic White females, and nine for Hispanic White females. Educational programs are needed to maintain the low-risk status of Southwestern Hispanics for cigarette-related diseases.

The New Mexico sealant program: a progress report.

In 1979, the dental health program of the New Mexico Health and Environment Department began a school-based sealant activity. Children in the first, second, third, sixth, and seventh grades in selected New Mexico communities were offered sealants through this sealant activity. During the 1984-85 school year, program staff began seeing several hundred sixth-grade students who had received sealants in either the first, second, or third grade. Tooth- and surface-specific data on the current condition of all the previously sealed occlusal surfaces were collected from all these previous recipients of sealants. During the 1985-86 school year, we found that sixth-grade students who received sealants as first, second, or third graders had 5.6 percent of the occlusal surfaces of their first permanent molars either decayed, missing, or filled. Their classmates who had not previously received sealants had 26.85 percent of the same tooth surfaces either decayed, missing, or filled. During the 1985-86 school year, the complete retention rates for sealants were found to be 67.36 percent after six years, 78.53 percent after five years, and 93.47 percent after one year. The partial retention rates were found to be 10.46 percent after six years, 10.63 percent after five years, and 3.04 percent after one year.

GIS habitat analysis for lesser prairie-chickens in southeastern New Mexico.

BACKGROUND: We conducted Geographic Information System (GIS) habitat analyses for lesser prairie-chicken (LPCH, Tympanuchus pallidicinctus) conservation planning. The 876,799 ha study area included most of the occupied habitat for the LPCH in New Mexico. The objectives were to identify and quantify: 1. suitable LPCH habitat in New Mexico, 2. conversion of native habitats, 3. potential for habitat restoration, and 4. unsuitable habitat available for oil and gas activities. RESULTS: We found 16% of suitable habitat (6% of the study area) distributed in 13 patches of at least 3,200 ha and 11% of suitable habitat (4% of the study area) distributed in four patches over 7,238 ha. The area converted from native vegetation types comprised 17% of the study area. Ninety-five percent of agricultural conversion occurred on private lands in the northeastern corner of the study area. Most known herbicide-related conversions (82%) occurred in rangelands in the western part of the study area, on lands managed primarily by the US Bureau of Land Management (BLM). We identified 88,190 ha (10% of the study area) of habitats with reasonable restoration potential. Sixty-two percent of the primary population area (PPA) contained occupied, suitable, or potentially suitable habitat, leaving 38% that could be considered for oil and gas development. CONCLUSION: Although suitable LPCH habitat appears at first glance to be abundant in southeastern New Mexico, only a fraction of apparently suitable vegetation types constitute quality habitat. However, we identified habitat patches that could be restored through mesquite control or shin-oak reintroduction. The analysis also identified areas of unsuitable habitat with low restoration potential that could be targeted for oil and gas exploration, in lieu of occupied, high-quality habitats. Used in combination with GIS analysis and current LPCH population data, the habitat map represents a powerful conservation and management tool.

Accidental firearm fatalities among New Mexico children.

STUDY HYPOTHESIS: Risk factors associated with unintentional gunshot fatalities among children include gender and race of the decedent, type of firearm used, and whether loaded guns are stored within the home. STUDY POPULATION: All New Mexico children 0 to 14 years old unintentionally killed by a firearm between 1984 and 1988. METHODS: The New Mexico Office of the Medical Investigator master mortality file was reviewed retrospectively to identify all unintentional firearm fatalities occurring in New Mexico children during a five-year period. Medical investigator, autopsy, and police reports were analyzed to identify epidemiologic factors associated with these deaths. Chi-square and Fisher's exact tests were used to analyze the data. RESULTS: Twenty-five unintentional firearm fatalities were identified. These deaths occurred most frequently among children playing with loaded firearms found within the home. A disproportionate number involved handguns. CONCLUSIONS: The study results provide a basis for preventive strategies that limit accessibility or decrease lethality of loaded firearms within the home.

Rapid rise and subsequent decline in prostate cancer incidence rates for New Mexico, 1989-1993.

Beginning in the late 1980s, a large increase in incidence rates for prostate cancer occurred in association with increased prostate-specific antigen (PSA) screening. In New Mexico, the increased screening was associated with earlier detection of cancers and decreased prostate cancer mortality, suggesting that PSA screening may be effective. PSA screening has become a controversial topic of public debate, and anecdotal reports from physicians indicated that prostate cancer screening practice patterns were changing in New Mexico. To assess whether PSA-associated trends in prostate cancer incidence were continuing, we examined incidence rates from 1989 to 1993 among men in New Mexico. From 1989 to 1992, age-adjusted rates increased substantially for non-Hispanic whites (77%), Hispanics (50%), and American Indians (27%). Although rates increased for all stages combined, incidence rates decreased for distant-stage disease, especially for non-Hispanic whites, indicating a continuing trend toward earlier detection. In 1993, incidence rates unexpectedly decreased from 203 to 158/100,000 in non-Hispanic whites, largely as a result of changes in rates in men over age 65 years. Although incidence rates decreased, the trend toward earlier detection was maintained for non-Hispanic whites. In contrast, among Hispanic and American Indians, rates did not change substantially between 1992 and 1993. Because the epidemic in prostate cancer was associated with increased PSA screening, it is likely that the trends for non-Hispanic whites are also related to PSA screening. We suggest that the decrease in rates and the continued stage shift are consistent with repeated screening of men in the population at risk.

Adolescent suicide and suicide attempts--Santa Fe County, New Mexico, January 1985-May 1990.

In February 1990, a physician notified the Office of Epidemiology, New Mexico Department of Health (NMDH), of a possible cluster of suicides among high school students in Santa Fe County, New Mexico, after two male high school students committed suicide within a 4-day period. Because of concerns by school officials that the number of students attempting suicide in 1990 had increased, the NMDH began an epidemiologic investigation.

Injury mortality in American Indian, Hispanic, and non-Hispanic white children in New Mexico, 1958-1982.

Childhood fatalities from injuries are a serious public health problem in New Mexico, a state which ranks second in the nation in injury-related mortality rates. To determine the extent of injury mortality in children in this state, and to examine time trends and differences in mortality rates in New Mexico's American Indian, Hispanic, and non-Hispanic white children aged 0-14 years, we analyzed vital records collected from 1958 to 1982. American Indian children experienced the highest mortality rates from all external causes combined. Among all three major ethnic groups, children aged 0-4 years were at the highest risk for injury fatalities. Unintentional injuries accounted for 85% of all injury-related deaths. Motor vehicle crashes and drowning were the first and second leading causes of death in all three groups, while other important causes of death included fire, choking on food or other objects, poisoning, and homicide. Although the fatality rates on most types of injuries decreased over the 25-year period, childhood fatality rates for motor vehicle crashes and homicide increased in each ethnic group. Despite the overall decrease in injury mortality rates in New Mexican children, the rates are excessively high compared to other states, especially in American Indian children.
