The prevalence of oral-maxillofacial trauma was high, and the main associated factors were place of residence and mechanism of aggression.

Results suggest that road traffic accidents represent the main cause of maxillofacial trauma among children and adolescents. However, results should be interpreted with caution due to the high heterogeneity.

Background/AimA large proportion of interpersonal violence results in maxillofacial injuries. The monitoring of maxillofacial injuries in the context of gender violence has been little explored. The aim of this study was to analyze trends in cases of maxillofacial injuries resulting from interpersonal physical violence considering the gender of the victim and perpetrator.Materials and MethodsA time‐series study was conducted. Data regarding maxillofacial injury cases due to interpersonal physical violence were collected from reports at a forensic institute of a city in northeastern Brazil, between 2008 and 2014 (84 months). Rates of interpersonal physical violence per 100 000 inhabitants were determined for each gender. A negative binomial regression model was used to evaluate trends. The cycle plot was used to investigate the occurrence of seasonality, considering subseries for each month.ResultsA total of 3561 reports were analyzed, revealing higher rates of female victims and male perpetrators throughout the series. There was no indication of seasonality. The annual percentage of injuries involving male victims reduced significantly by 6.8% (P < .001), while injuries involving female victims increased significantly by 4.5% (P = .002). Regarding perpetrators, rates remained constant over time, following the same pattern for both genders.ConclusionsThe data demonstrate greater victimization involving maxillofacial injuries against women perpetrated more often by men, with a trend toward an increase in female victims and a reduction in male victims.

The occurrence of facial trauma in terrestrial transport accident victims tends to affect a greater proportion of young and male subjects, and the most prevalent accidents involve motorcycles.

Abstract

ABSTRACT:Objective: The aim of this study was to describe the profile of violence against women in different life cycles, according to the sociodemographic characteristics of the victims and offenders. Methods: A crosssectional and exploratory study was performed based on 1,388 police reports during a four-year period, in a metropolitan area of Northeast Brazil. The dependent variable was the type of aggression suffered by the victims. The independent variables were sociodemographic characteristics of the victims and offenders. Statistical analysis included the χ 2 test (p < 0.05) and the decision tree analysis, through the Chi-squared Automatic Interaction Detector (CHAID) algorithm. Results: Cases of physical abuse (n = 644) were the most common, followed by threat (n = 415) and verbal aggression (n = 285). The violence profiles could be explained by the relationship between victims and offenders (p < 0.001) and age of the victims (p = 0.026 in Node 1; p = 0.019 in Node 3). Conclusion: It was observed that women in different stages of life are more exposed to different types of violence.

BACKGROUNDPatients with diabetes mellitus have been associated with a number of changes in the oral cavity, such as gingivitis, periodontitis, mucosal diseases, salivary dysfunction, altered taste, and burning mouth.OBJECTIVESTo determine the prevalence of oral mucosal lesions in patients with diabetes mellitus.METHODSA cross-sectional observational study between August and October 2012 with a convenience sampling was performed for 51 patients with diabetes mellitus (type 1 and type 2). The study consisted of two phases: 1) a questionnaire application; 2) intraoral clinical examination. For the analysis of data, we used descriptive statistics, Fisher's exact test in bivariate analysis (significance level of 0.05), and Poisson Regression.RESULTSThe prevalence of oral lesions was 78.4%. Traumatic ulcers (16.4%) and actinic cheilitis (12.7%) were the most prevalent lesions. The lips (35.3%) and tongue (23.5%) were the most common location. The bivariate analysis showed an association with the type of diabetes, and two variables (age and comorbidity) were quite close to the significance level. In the Poisson Regression analysis, only diabetes type 2 remained significant after adjusting the model.CONCLUSIONSThe results of this study show a high prevalence of oral mucosal lesions in diabetic patients. The oral mucosal lesions are mostly associated with diabetes type 2.

BackgroundA prolonged activated partial thromboplastin time (APTT) of unknown cause is one of the most frequent reasons why outpatients are referred for hemostasis consultation. Nevertheless, very few data are available on the relative contribution of individual causes of this common clinical scenario. Here, we present a systematic evaluation of all causes of APTT prolongation in a consecutive population of outpatients referred for specialized hemostasis consultation during a 14‐year period.MethodsAll cases referred to an academic specialized hemostasis outpatient unit due to APTT prolongation of unknown etiology whose prolonged APTT was confirmed in the first visit were included in the study. Data were obtained from the electronic medical records.ResultsAmong 187 consecutive patients, the most frequent causes were antiphospholipid antibodies in 22.6%, contact pathway factor deficiencies in 17.4%, other coagulation factor deficiencies in 11.6%, and vitamin K deficiency/liver disease in 11.6%. A definite cause was not identified in 22.1% of patients. Presence of antiphospholipid antibodies, and absence of bleeding symptoms were both associated with significantly longer APTT values compared to other categories/clinical scenarios. The investigation of each case required a mean of 18.2 additional tests per patient, with estimated costs ranging from US$191.60 to US$1055.60.ConclusionsOur results describe the main causes of APTT prolongation in outpatients, as well as estimates of resource use required to investigate this condition, thus providing evidence supporting the importance of measures to minimize the indiscriminate use of this assay.
