Título: Craniofacial pain of cardiac origin is associated with inferior wall ischemia. Autor: Kreiner, Marcelo; Álvarez-Vaz, Ramón; Waldenström, Anders; Michelis, Virginia; Muñiz, Rosana; Isberg, Annika Resumen: Aims: To investigate possible associations between the presence of craniofacial pain of cardiac origin and the location of cardiac ischemia and conventional risk factors. Methods: A total of 326 consecutive patients with confirmed myocardial ischemia (192 males, 134 females, mean age 64 years) were studied. Demographic details, health history, risk factors, prodromal symptoms, electrocardiogram (ECG) findings, and pain characteristics during the ischemic episode were assessed. The location of the ischemia according to the ECG findings was categorized as anterior, inferior, or lateral. Univariate chi-square analyses and a multivariate logistic regression model were used for data analysis. Two age subgroups (<65 and > 65) were established when controlling for covariates. Results: Craniofacial pain of cardiac origin was significantly associated with an inferior localization of cardiac ischemia (P < .001) and was more frequently reported in diabetic patients (P = .014). Thirty-eight patients (12%) did not experience chest pain during the myocardial ischemia. Nine patients (3%) experienced a prodromal angina episode without chest pain. Conclusion: The occurrence of craniofacial pain during myocardial ischemia, with or without an acute myocardial infarction, was associated with ischemia within the inferior wall. This result suggests the involvement of the vagal afferent system in the mechanisms of craniofacial pain of cardiac origin.

Modeling in an oral health study through two statistical methods in Uruguay

Título: Modeling in an oral health study through two statistical methods in Uruguay Autor: Massa, Fernando; Berberian Bakerdjian, Natalia Madelaine; Álvarez-Vaz, Ramón Resumen: In epidemiological studies it is common practice to work with binary variables that reflect the presence of certain diseases, which in turn may be associated with another set of variables, that in general are assumed as risk factors of the former. In the field of epidemiological studies referred to oral health, it is common to inquire about the relationship between the presence of some pathologies and certain characteristics of the study participants through generalized linear models (GLM). However, this type of analysis is usually carried out for each variable of interest separately and at no time is a measure obtained that summarizes the status of each participant. The objective was to apply and compare two methodologies; one applying classical approach of explaining each oral disease separately from a set of explanatory variables and another using item response theory (IRT) models (specifically the Rasch model) since they allow the joint analysis of a set of variables obtaining an individual assessment as a by-product, which in this case is interpreted as “sickness proneness”. On the other hand, the analysis presented here extends the Rasch model including a linear predictor that allows to investigate about the possible effect of several factors on the propensity of the individuals to suffer the different pathologies. Our results found evidence of an effect of gender, insufficient physical activity (IPhA) and age on general proneness to oral diseases.

Título: The role of contextual and individual factors on periodontal disease in Uruguayan adults. Autor: Lorenzo Erro, Susana; Massa, Fernando; Álvarez-Vaz, Ramón; Correa, Marcos Britto; Peres, Marco Aurélio; Schuch, Helena Silveira Resumen: The present study aimed at understanding the relationship between periodontitis and socio-contextual and individual determinants of health. Data from “The First Uruguayan Oral Health Survey, 2011”, which included 223 and 455 individuals with 35–44 and 65–74 years old respectively, were used. A stratified, multistage cluster ampling design was adopted (cities with ≥ 20.000 residents). Periodontitis was assessed using the modified Community Periodontal Index (CPI) and clinical attachment loss (CAL) (periodontal pocket and CAL ≥ 4 mm). Independent variables included contextual socioeconomic status (SES) measured by proportion of houses with Unsatisfied Basic Needs (UBN) and individual demographic and behavioral factors. Logistic regression multilevel models were generated. Living in contexts with a higher UBN was associated with higher odds for periodontitis in both age groups, even when adjusting for individual level variables (odds ratio [OR] = 1.51, 95%CI = 1.42–1.60 and 1.31, 95%CI = 1.21–1.42, respectively). Being male or heavy smoker increased the odds of periodontitis in this population for both age groups. Social structure impacts periodontal disease by modifying individual socioeconomic situations: in better socioeconomic context, UBN acts increasing the protector role of socioeconomic situation but in a poverty context the role is attenuated. Conclusions for this study are that periodontitis varies across contextual socio-demographic groups being higher in the population with a lower SES, challenging health authorities to integrate oral health into national non-communicable diseases programs.

Determinación del plano de orientación y de la dimensión vertical: técnica del mini rodete

Título: Determinación del plano de orientación y de la dimensión vertical: técnica del mini rodete Autor: Braun, José Resumen: Se pretende simplificar la técnica para determinar el plano de orientación y utilizarlo como guía para establecer la dimensión vertical. Se prescinde de la orientación antropométrica clásica (Plano de Camper o de Frankfort) y se jerarquiza la relación con el plano de orientación con los factores mecánicos, estéticos y funcionales. A dichos efectos es necesario conocer determinadas referencias a nivel anterior, medio y posterior tanto en el rodete superior como inferior. Descripción: Fascículo corresponde con la Serie Próteis Nº 3
