Treatment protocol for ” Mestizo nose” with open rhinoplasty. The aim of this study was to develop an operative sequence to guide plastic surgeons on how to handle the challenges of ” Mestizo nose” during rhinoplasty. This type of nose has characteristics quite different from the Caucasian nose. Rhinoplasties on Mestizo nose represent a surgical challenge because of the anatomical characteristics of a weak frame and thick skin.
The Hispanic population has grown, and nowadays a large number of patients requesting rhinoplasty within the US belong to this ethnic group. We have developed an operative sequence for the treatment fundamentalees Mestizo nose.

This operative sequence has been tested in rhinoplasties All were primary cases. An algorithm on how to approach the different types of Mestizo nose is presented. We had overall good results using our algorithm, with an improvement in the nasal aesthetics of about Complications were postoperative bleeding 1.
We present ten complete cases to show our surgical results. This operative sequence has allowed us to get predictable and reliable surgical outcomes when used in Mestizo rhinoplasty operations. We think it can be very useful for every plastic surgeon who performs Mestizo nose rhinoplasty, although not all steps need to be performed in every case.
There are currently about million people with diabetes worldwide, a figure likely to increase to million by InMexico was the second Latin American country and sixth in the world in prevalence of this disorder with nearly Type 2 diabetes T2D is the main kind of diabetes and its etiology is complex with environmental and genetic factors involved.
Indeed, polymorphisms in several genes have been associated with this disease worldwide. To estimate the genetic epidemiology of T2D in Mexican mestizos a systematic bibliographic search of published articles through PubMed, Scopus, Google Scholar, and Web of Science was conducted. Just case-control studies of candidate genes about T2D in Mexican mestizo inhabitants were included. Nineteen studies that met the inclusion criteria were found. Overall, 21 of the 41 analyzed genes were associated with T2D in Mexican mestizos.
Such a genetic heterogeneity compares with findings in other ethnic groups. Nasal valve evaluation in the Mexican-Hispanic mestizo nose. Our aim in this study was to determine the angle of the internal nasal valve in Mexican patients with the ” mestizo nose” feature and without nasal obstructive symptoms. The angle of the internal nasal valve was measured in 30 patients without obstructive symptoms.
The measurement of the angle of the internal nasal valve was made in sexagesimal degrees using Golden Ratio v3. Statistical analysis was performed using Excel v We believe it is necessary to undertake a second study and add an airflow resistance measurement with a rhinomanometry procedure so we can compare the results with those in the Caucasian population.
MexicanoMexican-American or Chicano? Although often considered to be homogeneous, the Hispanic community contains many culturally diverse groups. In the United States today, those of Mexican heritage–by far the largest subgroup within the Hispanic community–can be further classified as Mexicano undocumented residentMexican American, or Chicano. There is a lack of information concerning the prevalence of asthma among ethnic groups of Mexico. Therefore, we sought to determine the prevalence of asthma in school children of two ethnic groups Tepehuanos and Mestizos of Durango state, Mexico.
To determine the prevalence of asthma in school children from two ethnic groups of Durango, Mexico. Four hundred and eight school children of Mestizo ethnicity and all school children of Tepehuano ethnicity of the whole Tepehuano region of Durango state participated in the study. For Tepehuano population a translator helped in submitting the questionnaires. Confirmation of asthma was performed by clinical examination, skin prick tests, and spirometry. Asthma was confirmed in 30 7.
There was an absence of asthma cases among the Tepehuano school children population of Durango state, Mexico. The prevalence of asthma in our Mestizo children population is low compared to those reported in other Latin American countries.
A mother or tutor who smokes at home might be a contributing factor of asthma in our Mestizo children. Although the drug-metabolizing enzyme CYP2D6 has been studied extensively in subjects of differing ethnicities, limited CYP2D6 pharmacogenetic data are available for the Amerindian population and Mestizos of Mexico. Tepehuano Amerindian subjects lacked the poor metabolizer PM phenotype, whereas in Mestizos the PM phenotype frequency was 6.
The Tepehuano population was found to have a low phenotypic and genotypic CYP2D6 diversity and differed from other Amerindian groups. On the other hand, the frequencies of the CYP2D6 variant alleles in Mestizos were similar to those reported for whites. The defective mutations of the enzyme and their frequencies change between different ethnic groups; however, the polymorphism of the CYP2C19 gene has not been studied in Colombian mestizos.
The aim of this study was to evaluate tmeas genotype and phenotype status of CYP2C19 in Colombian mestizosin order to contribute to the use of appropriate strategies of drug therapy for this population.
Methods subjects were genotyped using the multiplex SNaPshot technique and a subgroup of 44 individuals received 20 mg of omeprazole followed by blood collection at 3 hours to determine the omeprazole hydroxylation index by HPLC.
No discrepancies were found between the genotype and phenotype of CYP2C Conclusion The frequency of poor metabolizers 1. The results of this study will be useful for drug dosage recommendations in Colombian mestizos. Lactase non-persistence and general patterns of dairy intake in indigenous and mestizo chilean populations. Lactase persistence LP is a genetic trait that has been studied among different countries and ethnic groups.
In Latin America, the frequencies of this trait have been shown to vary according to the degree of admixture of the populations. The objective of this study is to better understand the relationship between this genetic trait and dairy intake in a multiethnic context through a synthesis of studies conducted in four regions of Chile.
Genetic differentiation and association between milk consumption and genotype frequencies were estimated. Dairy intake was below the nutritional recommendations for the four groups, and extremely below recommendations among the indigenous populations. Association between milk intake and LP was found in Santiago and Rapanui populations.
America Sin Nombre 20
Although the frequency of LP varies among the populations according to their degree of admixture, dairy consumption was very low across the populations. Given that the association between milk consumption and expected phenotype was found only in two of the populations analyzed, it seems that lactase non-persistence LNP is not the only pedagobia for dairy avoidance. Thus, it is suggested that SES and cultural preferences are likely affecting dairy consumption.
This study of Mexicano resistance against coercive identity formation schooled ethnicity in a small south Texas town focuses luuis a particular facet of ethnic selfhood: The CT polymorphism of the methylenetetrahydrofolate reductase gene in Mexican mestizo neural-tube defect parents, control mestizo and native populations.
The CT mutation of the methylenetetrahydrofolate reductase MTHFR gene, associated with the thermolabile form of the enzyme, has reportedly been found to be increased in neural-tube defects NTDthough this association is still unclear. Funvamentales group of mestizo parents of NTD children and five control populations: Genotype frequencies were in agreement with the Hardy-Weinberg expectations in all six populations. Among controls, differences between M and individual native groups fudamentales NS 0.
Otherwise, CT in Mexico is very frequent, especially in Huichol and Purepecha natives, as compared with other groups world wide.
Evaluation of forensic and anthropological potential of D9S in Mestizos and Amerindian populations from Mexico. Aim To carry out a deeper forensic and anthropological evaluation of the short tandem repeat STR D9S in five Mestizo populations and eight Amerindian groups from Mexico. Genotypes were analyzed with the GeneMapper ID software. In each population we estimated statistical parameters of forensic importance and Hardy-Weinberg equilibrium. Results Amerindian and Mestizo populations showed high frequencies of the allele 9 and 16, respectively.
Conclusion This study evaluated the ability of D9S to be used for human identification purposes and demonstrated its anthropological potential to differentiate Mestizos and Amerindian populations. A group of volunteers aged 18 through 59 years were recruited for the study: The classification of nutritional status was through body mass index BMI.
Clinical evaluations, including anthropometry and lipid profiles, were performed to ascertain the health of the participants. Circulating leptin levels were determined in blood samples after at 08 hours of fasting. The healthy subjects were classified according to BMI: Leptin concentration and its relationship to BMI are associated with ethnicity.
Similarly, linkage disequilibrium test demonstrated no association between pair of loci. The power of exclusion and power of discrimination values were Genetic relationship analysis regarding Mestizo populations from the main geographic regions of Mexico suggests that the Center and the present South regions conform one population cluster, separated from the Southeast and Northwest regions. Lactase persistence and dairy intake in Mapuche and Mestizo populations from southern Chile.
Lactase persistence LP occurs at a very low frequency in indigenous populations from Latin America, offering an opportunity to understand the relationship between this genetic trait and patterns of dairy consumption.
In addition to genotyping for LP, participants were surveyed in relation to general perception and consumption habits of dairy products. The survey reported that pedagogiw main reasons for avoidance of dairy were the gastrointestinal symptoms after dairy intake and cultural dietary habits. The interaction between low LP genotype frequency, low dairy intake, and sociocultural determinants is afturo discussed in the light of their potential health outcomes. Risk factors and impact on bone mineral density in postmenopausal Mexican mestizo women.
Considering that the Mexican mestizo population seems to be the result of a genetic admixture, we proposed that further research is needed to evaluate the role of ethnicity in conjunction with health-related factors to better understand arhuro differences in bone mineral density BMD. The aim of this study was to analyze several risk factors related to the development of osteoporosis dundamentales postmenopausal Mexican mestizo women.
We included postmenopausal Mexican mestizo women. A structured questionnaire for risk factors was applied and BMD was measured in total hip and lumbar spine by dual-energy x-ray absorptiometry. Nonconditional logistic regression was used to estimate crude and adjusted odds ratio. Using World Health Organization criteria, In addition, we find that body mass index is positively associated with BMD.
Because of the heterogeneity of the Mexican mestizo population, the risk factor for osteoporosis may not be the same in different ethnic fundamenales. Mexican mestizo population sub-structure:
