Folk remedies as indicators of common illnesses: examples from the United States-Mexico border.

A sample of 1235 case examples of remedios caseros (home remedies) were analyzed to determine the characteristics of the ethnopharmacological resources currently in use in Mexican American communities along the eastern end of the United States-Mexico border. The data analysis confirms that there is a core group of most frequently used remedies that constitute the bulk of the home treatment of common ailments in that area. The data further indicate that there is a relatively well-defined group of ailments that are considered to be more amenable to ethnopharmacological intervention than to treatment by the conventional medical system. Some of the remedios (both botanical and non-botanical) are presented, and a preliminary model of ailments that receive treatment from home remedies, as opposed to medical treatment, is proposed.

Chemical bases for medicinal plant use in Oaxaca, Mexico.

Fifty-eight medicinal plants used for the management of reproduction and the treatment of women's reproductive health problems in an indigenous community in southern Mexico are described. The efficacy of these plants is assessed according to both community members' understandings of the therapeutic effects they seek and the standards of conventional Western medicine. The majority of the plants contain chemicals which would appear to enable them to accomplish their intended effects in either or both the popular and the conventional medical systems.

A study of four medicinal plant complexes of Mexico and adjacent United States.

A survey of medicinal herbs in markets of central and northern Mexico and southwestern United States revealed the existence of plant complexes of different species sharing common names, morphological and aromatic characteristics, and uses. Four complexes (with the "label" species listed first) discussed include: "cachani" with Roldana sessilifolia, Iostephane madrensis, Liatris punctata, Psacalium sp., and Potentilla sp.; "chuchupate" with Ligusticum porteri and Myroxylon balsamum; "hierba anís" with Tagetes lucida, T. filifolia, T. micrantha, Artemisia dracunculus, Pimpinella anisum, and Illicium verum; and "matarique" with Psacalium decompositum, P. peltatum, P. sinuatum, P. sp., and Acourtia thurberi. The distribution analysis of utilization and natural occurrence of plants in each complex indicated the presence of a dominant or "label" plant whose use extended beyond its natural range and which had substitutes derived from local plants that were not registered far beyond their respective natural ranges.

Medicinal plants used in some rural populations of Oaxaca, Puebla and Veracruz, Mexico.

Within Mexico's floristic abundance, plants with curative properties are outstanding due to their popularity in handling several illnesses, a fact that becomes specially important for the social groups of the tropical regions. In this paper the results of an ethnobotanical study carried out in 57 rural populations from the Mexican states of Oaxaca, Veracruz and Puebla are presented; questionnaire and interview methods were applied, with special attention to the use of plants for medical purposes. The most relevant results were: the taxonomic determination of 237 vegetal species from which 399 curative products are obtained, in order to combat 57 illnesses, the most frequent of which are those related to the digestive system, the skin, the reproductive system and those of supernatural origin, which can only be treated by the use of plants in special ceremonies known as 'limpias', due to their peculiar condition.

Indigenous phytotherapy of gastrointestinal disorders in a lowland Mixe community (Oaxaca, Mexico): ethnopharmacologic evaluation.

Gastrointestinal disorders are one of the major health problems in developing countries. Sixty-five plants used popularly in the treatment of such disorders in a Mixe Indian community in Oaxaca (Mexico) and collected during a fieldstudy of 15 months are described. According to indigenous criteria a plant is used in the treatment of a certain illness because of the plant's characteristic smell and taste. Plants with astringent properties are particularly valued to treat diarrhoea and dysentery. Bitter, aromatic and bitter-aromatic plants are especially employed to treat gastrointestinal cramps and pain. Additionally, the efficacy of these plants was evaluated using ethnobotanical, phytochemical and pharmacologic information on the plants. The majority of the plants contain chemicals that may produce the effects desired by the Mixe. Frequently tannin-containing drugs are used to treat diarrhoea and dysentery. A large number of the plants used by the Mixe in the treatment of gastrointestinal pain contain essential oil or bitter principles. As a result of this evaluation, plants were selected which should be studied phytochemically and pharmacologically with priority, to evaluate further their potential in the treatment of gastrointestinal disorders.

Parasitological and microbiological evaluation of Mixe Indian medicinal plants (Mexico).

Medicinal plants are an important health resource in many regions of the Americas and are of particular importance to many Indian communities. Based on a recent ethnobotanical study in Mexico, we investigated the activity of 29 plant extracts against Entamoeba histolytica, three bacteria (Bacillus subtilis, Escherichia coli, and Micrococcus luteus) and two fungi (Cladosporium cucumerinum and Penicillium oxalicum). After separation of these extracts between CH2Cl2 and H2O the resulting phases were also evaluated.

Lomefloxacin (SC-47111 or NY-198). Comparative antimicrobial activity against 2002 clinical isolates from hospitals in Mexico City.

A new difluorinated quinolone, lomefloxacin, was shown to have potent in vitro activity against a broad spectrum of bacteria, including multiresistant strains isolated from patients with severe infections in three hospitals in Mexico City. Whereas its activity was comparable to that of another fluoroquinolone (enoxacin), the pharmacokinetic advantages offered by lomefloxacin may be a significant benefit in clinical use.

New Mexico safety restraint law: changing patterns of motor vehicle injury, severity, and cost.

The impact of the New Mexico safety belt law on patterns of injury, severity, and cost was evaluated (using an emergency department data base). Data collected from November 1985 through February 1986 compared the 2 months before the January 1986 law with 2 months after. Before the law, 22.2% of the 379 injuries included abrasions, contusions, and lacerations to face, neck, and head. Following the law, this category constituted only 13.8% of 356 injuries, representing a reduction of 38% (P less than .05). Cost and injury severity scores (ISS) for 436 injured patients covered by the law were not significantly different between the pre- and post-seatbelt law periods. However, significant cost and severity differences were observed after the law between belted and nonbelted occupants: +2,569 compared with +662; ISS of 3.6 compared with 2.0 (P less than .05). Methodologic problems of an emergency department-based study and the need for E coding (external causes of injury) are discussed.

Comparisons of mesiodistal and buccolingual crown dimensions of the permanent teeth in three populations from Egypt, Mexico, and the United States.

The purpose of this study is to examine the mesiodistal and buccolingual crown dimensions in three populations--57 subjects (35 boys and 22 girls) from Iowa City, Iowa; 54 subjects (30 boys and 24 girls) from Alexandria, Egypt; and 60 subjects (26 boys and 34 girls) from Chihuahua, Mexico. All subjects had normal Class I occlusion, with no history of orthodontic treatment. Comparisons of single teeth as well as sums of groups of teeth were performed between boys and girls within and between the two populations. The analysis of variance general linear models procedure was used for statistical comparisons. The findings from this investigation indicated that (1) differences between antimeres are of small magnitude and of no statistical significance; (2) all populations have significant differences in tooth dimensions between the sexes with boys having larger canines and first molars; (3) there is greater variation in the buccolingual than in the mesiodistal dimensions among the three populations; (4) there is a greater similarity in tooth dimensions among the boys from the three populations than among the girls, but the magnitude of these differences is considered to be of little clinical significance; and (5) standards for the buccolingual diameters were developed for the three populations. As a result, it was concluded that prediction equations used for space analysis in the mixed dentition to determine tooth size-arch length discrepancies in the Iowa population can also be used for persons from Egypt and from the northern part of the Mexican Republic, with some suggested modifications.

Geographic variability in alcohol-related crashes in response to legalized Sunday packaged alcohol sales in New Mexico.

On July 1, 1995 the state of New Mexico lifted its ban on Sunday packaged alcohol sales. Legislation lifting the ban included a local option allowing individual communities within the state to hold an election to reinstitute the ban on Sunday packaged alcohol sales. Previous research has shown a clear statewide increase in alcohol-related crash and crash fatality rates after the ban was lifted. The goal of this study is to measure county-level variability in changes in alcohol-related crash rates while adjusting for county socio-demographic characteristics, spatial patterns in crash rates and temporal trends in alcohol-related crash rates. Bayesian hierarchical binomial regression models were fit to the observed quarterly crash counts for all counties between July 1, 1990 and June 30, 2000. Results show marked variability in the impact of legalized Sunday packaged alcohol sales on alcohol-related crash rates. Relative risks of an alcohol-related crash for the post-repeal versus pre-repeal period vary across counties from 1.04 to 1.90. Counties with older population suffered a greater negative impact of legalized Sunday packaged alcohol sales. Counties with communities that quickly passed the local option to re-ban packaged sales on Sundays were able to mitigate most of the deleterious impact of increased alcohol availability that was observed across the state.

Echinococcus granulosus cattle strain identification in an autochthonous case of cystic echinococcosis in central Mexico.

Echinococcosis is a frequent hepatic parasitic disease in several countries but it is practically absent in Mexico. A cattle strain of Echinococcus granulosus was identified by RAPD, PCR-RFLP and mitochondrial CO1 gene analysis in an autochthonous case. The parasite was obtained after a laparoscopic excision of a liver cyst from a patient that was symptomatic for 6 years but mis-diagnosed before hospitalization.

Epidemiological risk for Trypanosoma cruzi transmission by species of Phyllosoma complex in the occidental part of Mexico.

Domestic and peridomestic triatomine populations were collected in three rural Mexican communities of Jalisco, Nayarit and Zacatecas states. Triatoma longipennis and T. picturata (Phyllosoma complex) were the principal species unequally distributed in the villages: T. longipennis was the main species in two communities and T. picturata in the third one. Peridomestic infestation and colonization indexes were remarkably high ranging from 26.1% to 50% and from 58.3% to 85.7%, respectively. Moreover, domestic (indoor) infestation was observed in only one of the communities infested by T. longipennis. The preliminary study of temporal variation indicates increasing trend of the triatomine population and infestation rates during the dry season. Triatomine infection rates ranged from 41.2% to 60.2% and all the flagellate isolates were assigned to T. cruzi I. The majority of the dwellings were built with modern building materials and the sanitary conditions were generally good. High peridomestic infestations must be considered as a risk factor of Chagas disease transmission and further studies are needed to better understand the peridomestic conditions favoring the establishment of the triatomines. The contribution of such study to enlarger knowledge of epidemiological features of Chagas disease in Mexico is considered.

United States epidemiology of hepatitis A: influenced by immigrants visiting friends and relatives in Mexico?

Among the industrialized nations, the United States annually receives the greatest number of immigrants as permanent residents. Immigrants from Mexico have represented the largest segment of the foreign-born population in recent decades, and continued growth of Mexican immigration is predicted for the decades ahead. The changing demographics of this population, including the emergence of new immigrant growth centers, will influence the future epidemiology of hepatitis A virus transmission in the United States. Travel home to the place of origin to visit friends and relatives (VFR) by both newly arrived and established Mexican immigrants constitutes a new group of travelers that now include intergenerational family units. Asymptomatic pediatric travelers-who acquire hepatitis A abroad and are infectious on return to American communities-contribute to the silent transmission of hepatitis A to playmates, caretakers, and contacts in households, daycare facilities, and elementary schools. Considering the expanded geographic distribution of Mexican immigrant settlement, the predicted increased diversity of pediatric populations in the United States over time, and the continued growth of VFR travel, a universal pediatric vaccine recommendation for hepatitis A immunization can help to prevent hepatitis A transmission in this country in the future.

High prevalence of metabolic syndrome in Mexico.

BACKGROUND: Our objective was to describe the prevalence of the metabolic syndrome using World Health Organization (WHO) and National Cholesterol Education Program (NCEP-III) definitions in a population-based survey. METHODS: We performed an analysis of data from a Mexican nationwide, population-based study. The population was composed of 2,158 men and women aged 20-69 years sampled after a 9-12 h fasting period. Prevalence of the metabolic syndrome as defined by the NCEP-III definition and WHO criteria was estimated and case characteristics were assessed. RESULTS: Age-adjusted prevalence was 13.61% for WHO criteria and 26.6% for the NCEP-III definition. Prevalence was 9.2 and 21.4%, respectively, in subjects without diabetes. Thirty five percent of affected cases were <40 years of age. In addition to criteria used for diagnosis, ca. 90% were either overweight or obese. In cases detected using WHO criteria, antihypertensive treatment or blood pressure reading >140/90 was found in 61.8%. The proportion of subjects who qualified for hypolipemiant treatment was lower: lifestyle modifications were needed in 42.1% and drug therapy was required in 18.9%. The same trends were found for cases detected using the NCEP definition. CONCLUSIONS: Prevalence of the metabolic syndrome in Mexico is high. A large proportion of affected cases qualify for preventive actions for complications of the metabolic syndrome (i.e., weight loss, antihypertensive or hypolipemiant treatment). These results provide data for planning therapeutic programs for Mexican patients with the metabolic syndrome.

Multiple myeloma in Mexico: a 20-year experience at a single institution.

BACKGROUND: In a 20-year period at a single institution, 66 cases of multiple myeloma (MM) were identified. The disease was less frequent in Mexico because in a multicenter study it represented 4.2% of all hematologic malignancies, whereas during this experience it was found to represent 7.7%. These figures contrast with those reported in Caucasians-10-15%. METHODS: There were two patients <40 years of age; median age was 66 years. Bone pain was present in 54%, fatigue in 66%, and weight loss in 47%. Anemia was present in 75% of females and in 96% of males at diagnosis; median hemoglobin was 10.2 g/dL; abnormal monoclonal spike had a median of 2.87 g/dL (range 0-9.9). Four cases (6%) of nonsecretory myelomas were identified. Bence Jones proteinuria was present in 51 cases (77%). Forty six individuals were followed for >3 months (97-7,054 days, median 2,371 days). RESULTS: Their survival (SV) was 51% at 540 days. Patients treated with melphalan/prednisone had a median SV of 33 months with a 72-month SV of 30%. Patients treated with vincristine/adriamycin/dexamethasone had an SV of 40% at 42 months, whereas those given high-dose chemotherapy and autologous stem cell rescue had an SV of 80% at 22 months. CONCLUSIONS: Clinical features of Mexican patients with MM were not significantly different from those reported for other populations; best results from treatment were observed in patients administered autologous stem cell transplantation.
