Is alcohol intake associated with breast cancer in Hispanic women? The New Mexico Women's Health Study.

OBJECTIVE: Previous studies have shown an increased breast cancer risk associated with modest or high alcohol intake, however, few of these studies have included Hispanic women. The alcohol/breast cancer association was investigated in a New Mexico (NM) statewide bi-ethnic study. DESIGN: A population-based, case-control study. METHODS: Incident breast cancer cases (N = 712), aged 30-74 years, were ascertained by the New Mexico Tumor Registry (NMTR). Controls (N = 844) were identified by random digit dialing and were frequency-matched for ethnicity, age-group, and health planning district. Data were collected via in-person interview, which included questions regarding recent and past alcohol intake and breast cancer risk factors. RESULTS: The highest level of recent alcohol intake, compared to no intake, was associated with breast cancer risk for postmenopausal Hispanic women (odds ratio [OR] = 2.0 95%, confidence interval [CI] 0.8-5.1, 42+ grams/ week) and postmenopausal non-Hispanic White women (OR = 2.2, 95% Cl 1.0-5.0, 148+ grams/week), although estimates were unstable and statistically non-significant. Lower recent alcohol intake (< 148 grams/week) was associated with reduced risk for non-Hispanic Whites (OR = 0.49, 95% Cl 0.35-0.69). This pattern was independent of hormone-receptor status and was present for both premenopausal (OR = 0.29, 95% Cl 0.15-0.56) and postmenopausal women (OR = 0.56, 95% Cl 0.35-0.90). Results for past alcohol intake and breast cancer association did not demonstrate any trends and were non-significant. CONCLUSIONS: Alcohol intake does not appear to have a consistent or significant association with breast cancer in Hispanic women.

Multistate outbreaks of Salmonella serotype Poona infections associated with eating cantaloupe from Mexico--United States and Canada, 2000-2002.

Three multistate outbreaks of Salmonella serotype Poona infections associated with eating cantaloupe imported from Mexico occurred in the spring of consecutive years during 2000-2002. In each outbreak, the isolates had indistinguishable pulsed-field gel electrophoresis (PFGE) patterns; the PFGE patterns observed in the 2000 and 2002 outbreaks were indistinguishable, but the pattern from 2001 was unique among them. Outbreaks were identified first by the California Department of Health Services (2000 and 2001) and the Washington State Department of Health (2002) and involved residents of 12 states and Canada. This report describes the investigations, which led ultimately to an import alert on cantaloupes from Mexico. To limit the potential for cantaloupe contamination, the Food and Drug Administration (FDA) continues to work with the Mexican government on a food-safety program for the production, packing, and shipping of fresh cantaloupes.

Laboratory evaluation of Vectobac as against Aedes aegypti in Monterrey, Nuevo León, Mexico.

Intensive use of the organophosphate insecticide malathion against adults and temephos against larvae of Aedes aegypti in Mexico over the past 30 years has led to problems requiring the use of new larvicides. Toward this objective, Bacillus thuringiensis var. israelensis (Bti), a target-specific and environmentally safer control agent, was evaluated. Laboratory bioassays were done to determine the susceptibility of 2nd- and 3rd-stage larvae of Ae. aegypti to Vectobac 12 AS (aqueous suspension, 600 ITU/mg). A median lethal concentration of 0.0104 ppm and a 95% lethal concentration of 0.18 ppm were determined after 24 h of exposure to the agent. The values obtained were adjusted for field application and were further tested in the field by the State of Nuevo León, Mexico Vector Control Program. Suspensions of Bti were poured into pipe-water trucks and transferred to domestic 200-gal metal water drums. Larval populations were reduced during a 2-week study period. However, residents complained about a fine dusty film on the water surface. Nevertheless, these results are promising for future Bti field applications.

Lower extremity amputation episodes among persons with diabetes--New Mexico, 2000.

Lower extremity amputation (LEA) is one of the most disabling complications of diabetes. Lower extremity problems tend to recur among persons because of underlying complications, including the loss of "protective" sensation. To define the burden of LEA among persons with diabetes in New Mexico, the New Mexico Diabetes Prevention and Control Program (DPCP) analyzed data from the Hospital Inpatient Discharge Database (HIDD) and the Santa Fe Indian Hospital (SFIH) from 2000 by linking hospital discharges to persons to create "episodes" of LEA. This report summarizes the findings of that analysis, which indicated that the age-adjusted rate of LEA by episode was approximately 3.5 times higher for American Indians (AIs) (11.4 per 1,000 persons with diabetes) than for non-Hispanic whites (3.3). To address this disparity, DPCP is collaborating with the Indian Health Service (IHS) to determine the needs for foot-care resources and education in AI communities.

Detection of human influenza virus in Yucatan, Mexico.

OBJECTIVE: Influenza virus is the most common cause of Acute Respiratory Infections (ARI) world wide. In patients with chronic condition, infection by the influenza virus can cause complications such as pneumonia which may have fatal outcome. The aim of this work was to determine the frequency of human influenza virus in outpatients with influenza-like illness (ILI) and in those patients admitted to hospital with community acquired pneumonia (CAP) in Yucatan, Mexico (October 1998-July 1999). MATERIALS AND METHODS: Throat swabs were collected from ILI and CAP patients and processed to detect respiratory viruses. All clinical samples were tested for seven respiratory viruses using a rapid indirect immunofluorescence test (IFI). Clinical samples with positive results for influenza virus by IFI were inoculated into chick embryo eggs and/or MDCK cells for viral isolation. All influenza virus isolates were typed using the WHO influenza Kit 1998-1999. RESULTS: A total of 288 clinical samples were collected. Influenza virus type A was diagnosed in 29 clinical samples (10%), no other respiratory viruses were identified. Influenza virus was present with 8.9% (17 out of 189) in ILI patients, whereas with 12.12% (12 out of 99) in CAP patients. Influenza virus was detected from December to July. Six viral isolates were obtained and identified as influenza A (H3N2). CONCLUSION: Human influenza virus is certainly a cause of ARI and pneumonia in Yucatan, Mexico. The results showed that influenza virus contributes to at least 8.9% of the ARI, and more importantly to 12% of CAP patients. Positive cases were present in a different pattern to temperate zones where the peak of incidence occurs during autumn and winter.

[The epidemiologic transition of the adolescents in Mexico].

OBJECTIVE: To identify the health status of adolescents in Mexico in their demographic, social and economic context. MATERIAL AND METHODS: A literature search and review of vital statistics, and opinion surveys were performed in order to asses the impact of the epidemiologic transition on the availability and priority of health services for adolescents. The Omran epidemiologic model was used to classify the demographic, social and economic characteristics of Mexican adolescents in efforts to define their impact on the epidemiologic transition of this age group. RESULTS: Demographic data are presented in the perspective of the epidemiologic transition which permit us to make inferences on the social conditions, growth patterns and health needs of this age group in Mexico. Data are presented regarding the demand and availability of health services, the impact of education and employment opportunities and the role of family and the economy on their well being. Other important aspects presented include the role of education on the sexual and reproductive health of adolescents and the threat of the AIDS pandemic in this age group. CONCLUSIONS: These findings reveal a sequence of variables that can no longer be addressed in the traditional problem oriented approach and strongly suggest a need to profile the health needs of adolescents in an integrated, holistic fashion with emphasis in health promotion and healthy life styles to favor their integral, just and equitable development, and also help focus the societal response in an integrated manner.

[Incidence some congenital defects in Monterrey, Mexico].

OBJECTIVE: In Mexico, the congenital defects (CD) in newborns represent the third cause of infant morbi-mortality. Incidence rates/1000 reported for our country vary from 8.15 (Puebla) to 32.90 (Distrito Federal). The aim of this study was to estimate the incidence of some CD in Monterrey, Mexico. METHOD: A transversal, prospective, descriptive, and observational study was carried out at the Hospital de Ginecologia y Obstetricia No. 23, IMSS during January 1995 to December 1999. The external CD were analyzed according to World Health Organization (WHO) and classified according to their topography distribution. RESULTS: A total incidence of 9.89 [(1309/132,369)* 1000)] was detected. The more frequent CD were: the nervous system (2.33), the chromosomal (1.67), osteomuscular (1.67) of face and neck (1.18), and reproductive system (0.81). The less frequent CD were: the digestive system (0.43), diverse syndromes (0.38), and skin (0.29). CONCLUSION: Even though the global incidence of DC observed in this study is into the rank informed in the national and international literature. Because of this incidence has a great variability, we considered important to homogenize diagnosis criteria for each DC. With this results it will be possible to carry out comparative cross-sectional studies to determine if they are similar or different and then, by association studies to establish its possible etiological factors.

[Economic evaluation of the demand of medical care for mental health in Mexico: schizophrenia and depression, 1996-2000].

Financing protection for both, users and providers of health care services is one of the main objectives of National Program of Health in Mexico, 2001-2006. In fact one of the elements of the present health care reform initiatives is need for the efficient allocation of financial resources, using resource allocation schemes by specific health care demands that combine both the economic, clinical and the epidemiological perspectives. The evaluation of such schemes has been approached in several ways; however, in the case of mental health services, there is dearth of studies that use economic assessment methods. Moreover, such studies are of limited scope, often a response to unmated health needs, disregarding the economic implication for health services production and financing and ensuing medical care market imbalances. This paper presents the results of an evaluative research work aimed to assess the average cost of depression and schizophrenia case management, the financial resources required to meet the health care demands by type of institution, period 1996-2000, in Mexico by type of health care provider. The case management average cost for schizophrenia was $211.00 US, and that for depression was $221.00 US. The demand of services for both conditions in each type of institution showed that the greatest relative demands (96% of the national total for depression and 94% of the national total for schizophrenia) occur in three institutions: IMSS, SSA and ISSSTE. The greatest demand of the health services for the two study condition corresponded to those insured by the IMSS, followed by those uninsured who use the SSA services, and those insured by the ISSSTE. The case management costs for mental conditions are in the middle range between hypertension and diabetes in the upper end, pneumonia and diarrhea in the lower end. The case managment costs of health care demands for the selected tracer conditions differ considerably among institutions for insure populations and those for uninsured populations, with a greater economic impact on-the former. Independent from differences found, these results allow the identification of economic evaluation indicators that could be used to design resource allocation schemes for each of the institutions included in this study.

[High prevalence of malnutrition among the indigenous early childhood population in Mexico. National Nutrition Survey 1999].

BACKGROUND: Malnutrition among the indigenous early childhood population is still currently a serious public health problem, and given that no specific studies affording the possibility of knowing the nutritional condition of this population, the question was posed of identifying the prevalence of malnutrition among the indigenous population of Mexico by means of the 1999 National Nutrition Survey. METHODS: A rural sample was selected from the Northern, Central and Southern regions where 70% or more of the population speak an indigenous language. The weight/age, height/age and weight/height Score Z desviations was calculated for 3,236 preschoolers and 4,899 school-age children. RESULTS: Nationwide and by regions, there were no difference by age group regarding the prevalences of the three indicators. By regions, for preschoolers, the South showed the highest prevalences of underheight (69.8%) and underweight (49.8%) than the North (respectively 36.1% and 22.6%), entailing statistically significant differences (p = 0.0002 and p = 0.04). For overweight and obesity, the North showed a 14.2% prevalence, and the South 5.6% (p < 0.05) for the same age group. CONCLUSIONS: The nutritional condition of the children studied reveals a geographical polarization, the greatest prevalences related to underheight and underweight children being found in southern Mexico, whilst those due to overalimentation were located in the North, this phenomenon possibly being due to lifestyles and availability of food differing from one region to the other.

[The health gap in Mexico, measured through child mortality].

OBJECTIVE: To estimate the health gap in Mexico, as evidenced by the difference between the observed 1998 mortality rate and the estimated rate and the estimated rate for the same year according to social and economic indicators, with rates from other countries. MATERIAL AND METHODS: An econometric model was developed, using the 1998 child mortality rate (CMR) as the dependent variable, and macro-social and economic indicators as independent variables. The model included 70 countries for which complete data were available. RESULTS: The proposed model explained over 90% of the variability in CMR among countries. The expected CMR for Mexico was 22% lower that the observed rate, which represented nearly 20,000 excess deaths. CONCLUSIONS: After adjusting for differences in productivity, distribution of wealth, and investment in human capital, the excess child mortality rate suggested efficiency problems in the Mexican health system, at least in relation to services intended to reduce child mortality.

Knowledge and beliefs about malaria transmission and practices for vector control in southern Mexico.

OBJECTIVE: To investigate the knowledge and beliefs about malaria transmission and practices for vector control in eight villages on the coastal plain of Chiapas, Mexico. MATERIAL AND METHODS: A cross-sectional survey was conducted during May and June 1995 in Chiapas, Mexico. A questionnaire to investigate family structure, knowledge on malaria transmission, preventive measures and attitudes towards seeking treatment was applied to both family heads of a sample of households. Associations were analyzed by estimating odds ratios with confidence intervals and p values, using bivariate and multivariate logistic regression methods. RESULTS: Malaria knowledge was poor and only 48% associated malaria with mosquito bites. The perceived benefit of indoor residual spraying was associated to a reduction of mosquitoes, a reduction in the numbers of cockroaches and rats, but only 3% associated it directly with the prevention of malaria transmission. Most villagers (97.6%) agreed with the indoor residual spraying of insecticides. Ninety nine percent of villagers had mosquito bednets, 75.7% used them all year round. Other measures used by villagers to prevent mosquito bites were smoke and mosquito coils. Above 40% of villagers self-medicated when any member of the family had a fever episode, but 51% attended proper health services (community dispensary, private physician, health worker). About 61% used pesticides for agricultural or livestock purposes and 55% applied themselves. Women had a greater participation as family health promoters, with 70% of the housewives being in charge of the application of self-protection preventive measures. CONCLUSIONS: Educational programs aimed at increasing awareness on the participation of mosquitoes on malaria transmission could promote community participation in malaria control in the region.

Tickborne relapsing fever outbreak after a family gathering--New Mexico, August 2002.

On August 2, 2002, the New Mexico Department of Health (NMDOH) and the Indian Health Service (IHS) were notified of a tickborne relapsing fever (TBRF) outbreak after a 1-day family gathering held in late July at a remote, previously uninhabited cabin located in a mountainous region of northern New Mexico (elevation: approximately 8,000 feet). Approximately 40 persons attended the event; at least half slept overnight in the cabin. This report summarizes the investigation of this outbreak, which indicates that prompt diagnosis and collaboration among clinicians and public health authorities can reduce morbidity associated with TBRF. Persons living in areas where TBRF is endemic should avoid sleeping in rodent-infested buildings, rodent-proof susceptible buildings, and consider fumigation of buildings that harbor rodents.

Diabetes in Mexico--a serious and growing problem.

According to a recent national health survey, the prevalence of self-reported diabetes in Mexico is 1.2%, but this figure reflects the relative youth of the Mexican population. Age-specific estimates are similar to those for the United States of America, where crude prevalence is higher. Given that self-reporting usually underestimates prevalence by at least 50%, there may be as many as 1.7 million persons with diabetes in Mexico, with a prevalence of approximately 6% in the age range 30-64 years. The average age at death for Mexicans with diabetes is 57 years, compared to 69 years for the population as a whole. Diabetes is the fifth most important cause of death in the Mexican population, and the third cause in people over 45 years of age, in whom it accounts for 10% of all deaths. There is evidence for important increases in diabetes-related mortality over time. Most studies indicate high rates of complications in Mexicans with diabetes and data show that their average length of hospital stay is almost twice as long as for non-diabetic patients. The annual cost of diabetes to Mexican society may be estimated at US$ 15 million for metabolic control, US$ 85 million for additional health services and US$ 330 million for indirect costs--in total, approximately three-quarters of all government spending on health care, or approximately US$ 450 per known diabetic person per year.

[The epidemiological panorama of cancer in Mexico, 1987].

The mortality, incidence, morbidity, partial data and opportune detection, of the main cancer types were reviewed from de information register corresponding to 1987, to analyze the epidemiological panorama of cancer in Mexico. The main causes of death in women were cervix uterine, breast, stomach and lung carcinomas, leukemias and lymphomas; and in men were lung, gastric, prostate, leukemias and lymphomas. The most frequent localization of women's new cancer cases were cervix uterus, breast, ovary, lymphoma, thyroid gland and endometrium; and in men were prostate, lymphoma, stomach, leukemia and lung. In according to tendencies about the main death rates in Mexico, we estimate that 55.3 by 100.00 inhabitants will be the rate of cancer deaths in the year 2000, numerical character virtually bigger considering demographic variation like human life's hope and increase population with cancer risk.

[First report on Neotoma micropus (Rodentia) as a reservoir of Trypanosoma cruzi in Mexico].

Using xenodiagnosis, two (8.0%) of 25 woodrats Neotoma micropus were found infected with tripanosome parasite in Vaquerias, a village in Nuevo Leon State, Mexico. The triatomine species developing infective metacyclic trypanosomes at week 12th were Triatoma pallidipennis, T. infestans and T. gerstaeckeri. Experimental infections using infected dejections were successfully conducted on laboratory mice (CD1 strain) confirming the vertebrate cycle of Trypanosome cruzi. The biological characterization of T. cruzi strains was demonstrated based on: 1) Triatomine developmental cycle. 2) A vertebrate host parasitic period up to 25-33 post-infection days, and. 3) Typical morphology of bloodstream trypomastigotes and amastigotes from myocardial nest. This is the first report of T. cruzi biologically characterized in Nuevo Leon, as well as a new report of N. micropus, increasing the list of reservoir hosts in Mexico.

[Epidemiology of mycetoma in Mexico: study of 2105 cases].

A survey was carried out in Mexico to determine the incidence and epidemiological characteristics of mycetoma. Data was collected from a total of 2105 cases of mycetoma throughout a 30 year period (1956-1985), with an average incidence of 70 cases per year. Results showed a sex distribution of 76.1% male and 23.9% females. Age distribution indicated a 35% between 16 to 30 and 23% between 31 to 40 year old population. Most cases occurred in land-workers (60.2%) and in housewives with rural residence (21.3%). Lesions occurred most frequently in lower limbs (64.1%), trunk (17.4%) and upper limbs (13.6%). The geographic distribution within Mexico revealed that the States with the highest incidence were: Jalisco, Nuevo León, San Luis Potosi, Morelos and Guerrero The predominant etiologic agents found 97.8% corresponded to actinomycetes, from which Nocardia brasiliensis (86.6%) and Actinomadura madurae (10.2%) showed the higher frequency. Eumycetoma (2.2%) was due to Madurella grisea and M. mycetomatis in most cases.
