Spatial-temporal distribution of maxillofacial injuries resulting from intimate partner violence against women.

BACKGROUND/AIM: Maxillofacial trauma resulting from intimate partner violence (IPV) represents an important oral health problem. In this sense, the aim of this study was to investigate the spatial-temporal distribution of maxillofacial trauma resulting from IPV against women, using a geostatistical approach. MATERIALS AND METHODS: An ecological study was carried out including the analysis of confirmed IPV cases against women treated at a Center for Forensic Medicine and Dentistry over a four-year observation period, as well as the evaluation of population data from the victims' places of residence extracted from the last demographic census of the Brazilian Institute of Geography and Statistics. Statistical analysis included: (i) finite mixture modeling to establish incidence trajectory patterns; (ii) Getis-Ord indicator (Gi*) for spatial autocorrelation; (iii) spatial regression analysis (p < .05). RESULTS: Two distinct trajectory patterns (TP1 and TP2) related to IPV incidence were identified using finite mixture modeling, suggesting spatial-temporal disparities at the regional level. In TP1, it was observed that IPV incidence was relatively low and remained stable over time, covering almost two-thirds (62.0%) of investigated spatial units. TP2 was characterized by higher IPV incidence with a tendency to increase in the last year, including more than one-third of neighborhoods (38.0%). Autocorrelation analysis showed a predominance of hot areas (hotspots) in the Eastern zone (p < .05) and in the Western zone (p < .05); and cold areas (coldspots) in the Northern zone (p < .05). In addition, statistically significant association was observed among neighborhoods with higher percentage of households with family householder without income and higher incidence of maxillofacial trauma resulting from IPV against women (ß = 5.305; SE = 1.741; p = .002). CONCLUSIONS: The findings indicate an association between higher IPV incidence against women, maxillofacial trauma, and socio-spatial vulnerability.

Identificação de corpo macerado por meio de fotografias intraorais exigidas por um plano de saúde odontológico: relato de caso pericial / Identification of macerated body by means of intraoral photographs required by a dental health plan: forensic case report

Introdução: Diante de casos de identificação humana, vários são os registros odontológicos que podem ser utilizados a fim de possibilitar a comparação Post-mortem para identificação. Objetivo: Por meio de um relato de caso pericial, demonstrar a possibilidade da identificação odontolegal a partir de registros odontológicos exigidos por plano de saúde. Relato do Caso: Em 2020, um cadáver do sexo masculino, com uma suspeita de identidade, chegou a um Instituto Oficial de Perícias do Nordeste brasileiro, em estado avançado de decomposição, com características do fenômeno de maceração. A família forneceu, após contato com o dentista do indivíduo, imagens do sistema de um plano odontológico no qual era beneficiário e exigia fotografias para auditoria e consequente liberação de tratamentos odontológicos. Após a disponibilização com poucas horas da descoberta do corpo, prosseguiu-se com o confronto dos dados Ante-mortem (AM) e Post-mortem (PM) para identificação odontolegal. Na ausência de pontos divergentes e havendo congruências relativas quanto ao formato da arcada, tratamentos odontológicos, presença e ausências dentárias, forma e posições dentárias, lesões de cárie, foi possível associar a identidade da vítima desaparecida ao corpo examinado. Conclusão: O caso evidencia a confiabilidade, rapidez e baixo custo do processo de identificação odontolegal por meio do confronto de características individualizadoras AM e PM, que só foi possível pela exigência de imagens intraorais pelo plano odontológico da vítima.

Introduction: In cases of human identification, various dental records can be used in order to help in the comparison of postmortem evidence. Objective: The aim of this study was to demonstrate by the forensic report that dental records, which are required by health insurance, could be utilized to obtain a positive identification of an individual. Case report: In 2020, the body of a male individual was referred to the Official Forensic Institute of Northeast Brazil, his body arrived in advanced stage of decomposition and shows signs of maceration. After contact the dentist of the individual, the family provide his teeth images from dental insurance plan that using them to authorize any dental treatment and for audit purposes. Afterwards the identification was made matching ante-mortem (AM) and post-mortem (PM) data. There are no irreconcilable discrepancies and the available data achieve a positive identification then the body examined matched with the missing victim. Conclusion: The case shows the reliability, rapid and cost-effective identification process through comparing AM data to PM evidences. This has only been possible due to the requirement for intraoral images by the victim's dental insurance plan

Firearms, Violence-Related Injuries, and Victimization Profiles: An Approach Using Cluster Analysis.

The aim of this study was to characterize the profile of nonlethal victims of urban violence by firearms and to describe traumas suffered by victims, according to a medical-legal and forensic perspective. A cross-sectional and exploratory study was conducted at the Center of Forensic Medicine and Dentistry in northeastern Brazil. The sample consisted of 233 victims of urban violence by firearm who presented some type of trauma. Descriptive and multivariate statistics using cluster analysis (CA) were performed. The TwoStep Cluster method was chosen to characterize the profile of victims. The night shift (56.8%) and the period corresponding to Saturdays (20.0%) and Sundays (20.4%) concentrated the largest number of occurrences. Cases of trauma in more than one region of the body simultaneously prevailed (31.8%). Based on the CA results, the formation of two clusters with distinct victimization profiles was verified. Cluster 1 was mostly characterized by younger single victims who suffered violence by firearm in the urban area perpetrated by an unknown perpetrator, resulting in greater occurrence of isolated upper and lower limb traumas. In contrast, Cluster 2 consisted essentially of older, married, or stable-union victims who experienced firearm violence in the suburban area, perpetrated by a known aggressor, resulting in greater occurrence of multiple traumas, that is, affecting several regions of the body at the same time. These findings reveal different risk groups for urban violence by firearms and traumas, contributing to the planning of strategies with emphasis on health care, prevention, and promotion.

Facial Injuries and the Gender Issue: Expressions of Violence in a Metropolitan Region of Northeastern Brazil.

The aims of this investigation were to describe the profile of men and women victims of violence and identify factors associated with the severity of facial trauma. A retrospective study was carried out from 762 records of victims attended at the Institute of Legal Medicine and Dentistry located in a metropolitan region of Northeastern Brazil. The dependent variable was type of facial trauma suffered by victims. Independent variables were the sociodemographic characteristics of victims, characteristics of aggressors and circumstances of violence. Descriptive, bivariate (c2 test) and multivariate statistics were made through logistic regression. Level of significance was set at p < 0.05. The mean age of victims was 29.78 years (SD=13.33). Based on the final regression model, male subjects [odds ratio (OR)=2.22, 95% CI=1.08-4.57, p=0.030], assaulted by other male subjects (OR=4.88; 95% CI=1.12-21.26; p=0.035) through instrument (OR=6.67; 95% CI=2.85-15.60; p<0,001) or mixed aggressions (OR=4.34; 95% CI=1.44-13.02; p=0.009) were more likely to exhibit facial bone fractures or dentoalveolar fractures. The findings highlight that men and women present important victimization differentials in relation to interpersonal violence and facial trauma. Victim's gender, aggressor's gender and mechanism of aggression may exert influence on facial trauma patterns.

Resumo Os objetivos desta investigação foram descrever o perfil de homens e mulheres vítimas de violência e identificar fatores associados à gravidade do trauma facial. Foi realizado um estudo retrospectivo de 762 prontuários de vítimas atendidas no Instituto de Medicina Legal e Odontologia de uma região metropolitana do Nordeste do Brasil. A variável dependente foi o tipo de trauma facial sofrido pelas vítimas. Variáveis ​​independentes foram as características sociodemográficas das vítimas, características dos agressores e circunstâncias de violência. Estatísticas descritivas, bivariadas (teste c2) e multivariadas foram feitas por meio de regressão logística. O nível de significância foi fixado em p<0,05. A idade média das vítimas foi de 29,78 anos (DP =13,33). Com base no modelo de regressão final, os indivíduos do sexo masculino [odds ratio (OR)=2,22, IC 95%=1,08-4,57, p=0,030], agredidos por outros sujeitos do sexo masculino (OR=4,88; IC 95%=1,12-21,26; p=0,035) por meio de instrumentos (OR=6,67; IC 95%=2,85-15,60; p<0,001) ou agressões mistas (OR=4,34; IC 95%=1,44-13,02; p=0,009) foram mais propensos a apresentar fraturas de ossos faciais ou fraturas dentoalveolares. Os achados apontam que homens e mulheres apresentam importantes diferenciais de vitimização em relação à violência interpessoal e trauma facial. O gênero da vítima, o gênero do agressor e o mecanismo de agressão podem exercer influência sobre os padrões de trauma facial.

Characteristics of Brazilian Offenders and Victims of Interpersonal Violence: An Exploratory Study.

The aim of this study was to characterize the profile of Brazilian offenders and victims of interpersonal violence, following a medicolegal and forensic perspective. A cross-sectional and exploratory study was performed in a Center of Forensic Medicine and Dentistry. The sample was made up of 1,704 victims of nonlethal interpersonal violence with some type of trauma. The victims were subject to forensic examinations by a criminal investigative team that identified and recorded the extent of the injuries. For data collection, a specific form was designed consisting of four parts according to the information provided in the medicolegal and social records: sociodemographic data of the victims, offender's characteristics, aggression characteristics, and types of injuries. Descriptive and multivariate statistics using cluster analysis (CA) were performed. The two-step cluster method was used to characterize the profile of the victims and offenders. Most of the events occurred during the nighttime (50.9%) and on weekdays (66.3%). Soft tissue injuries were the most prevalent type (94.6%). Based on the CA results, two clusters for the victims and two for the offenders were identified. Victims: Cluster 1 was formed typically by women, aged 30 to 59 years, and married; Cluster 2 was composed of men, aged 20 to 29 years, and unmarried. Offenders: Cluster 1 was characterized by men, who perpetrated violence in a community environment. Cluster 2 was formed by men, who perpetrated violence in the familiar environment. These findings revealed different risk groups with distinct characteristics for both victims and offenders, allowing the planning of targeted measures of care, prevention, and health promotion. This study assesses the profile of violence through morbidity data and significantly contributes to building an integrated system of health surveillance in Brazil, as well as linking police stations, forensic services, and emergency hospitals.

Spatial distribution of maxillofacial injuries caused by urban violence: An ecological analysis to identify high-risk areas.

OBJECTIVES: To investigate the spatial and spatial-temporal distribution of oral and maxillofacial injuries caused by urban violence, as well as to identify underlying disparities at regional level through a geostatistical approach. METHODS: This was a historical ecological cohort study of trauma cases caused by urban violence using aggregate data from victims assisted in a Brazilian medical-forensic service between January 2012 and December 2015. The longitudinal patterns of change observed in each geographic area (neighbourhoods) were evaluated using the finite mixture model (FMM). The spatial autocorrelation of events was investigated using the Getis-Ord Indicator (Gi*) to identify significant hot and cold spatial clusters. With a spatial regression model, it was also found when socioeconomic variables, residential infrastructure and neighbourhood infrastructure were associated with high incidence rates. The significance level was set at P ≤ 0.05. RESULTS: The finite mixture model revealed three different patterns of longitudinal trajectory of the incidence of oral and maxillofacial trauma caused by urban violence (TP1 to TP3, P < 0.05). TP1 was characterized by an incidence that remained stable and high over time, comprising 17.4% of the city's neighbourhoods. In TP2, it was observed that the incidence was moderate, with a slightly increasing trend in the last year evaluated, representing around 41.8% of the sample. In contrast, in TP3, it was found that the incidence was relatively low and remained stable over time, accounting for about 40.8% of the sample. The Getis-Ord (Gi*) statistic identified significant high-risk clusters in the western (P < 0.05), southern (P < 0.05), and eastern regions (P < 0.05) and low risk in the northern region (P < 0.05). The spatial regression model indicated significant association between areas with unfavourable socioeconomic conditions and higher incidence of events (ß = 0.178, SE = 0.046, P < 0.001). CONCLUSIONS: Clusters demarcating areas with high socio-spatial vulnerability for urban violence and oral and maxillofacial injuries were identified. The findings highlight the need to improve living conditions in segregated urban areas and develop intersectoral actions to improve living conditions, employment, public safety, social support, health care and prevention.

Traffic accidents, maxillofacial injuries and risk factors: A systematic review of observational studies.

AIM: This study aimed to evaluate the scientific evidence regarding the risk factors for maxillofacial injuries among victims of traffic accidents. METHOD: A systematic review of articles published until February 2017 was carried out in the following databases: PubMed, Web of Science, Scopus, and Cochrane Library. Studies were selected by two independent reviewers (Ï° = 0.841). The risk of bias in the selected studies was assessed using an adapted version of the Newcastle-Ottawa Scale for observational studies. RESULTS: A total of 2703 records were found, of which only three articles fulfilled the inclusion criteria and were analyzed, including 422 244 patients. The male/female ratio ranged from 3.4: 1 to 6: 1. All eligible studies performed the multivariate statistical analysis. Eleven risk factors for maxillofacial traumas were identified: victim's gender (P < 0.05), age group (P < 0.05), residence region (P < 0.05), impact characteristics (P < 0.05), increased net change in velocity due to collision (P < 0.05), increase in occupant's height (P < 0.05), nonuse of protective equipment (P < 0.05), type of accident (P < 0.05), time of occurrence (P < 0.05), lesion severity (P < 0.05), and occurrence of concomitant lesions (P < 0.05). CONCLUSION: The results suggest that sociodemographic characteristics, as well as those related to the collision patterns and circumstances of traffic accidents, may influence the occurrence of maxillofacial injuries. However, the results should be interpreted with caution due to the high heterogeneity among studies.

Social determinants of health and maxillofacial injuries in children and adolescents victims of violence: A novel GIS-based modelling application.

BACKGROUND: Physical violence against children and adolescents comprises a serious public health problem and often results in oral and maxillofacial traumas. Social determinants may favour the occurrence of these events, but few studies have critically evaluated the interaction between social and geographical risk factors. AIMS: To investigate the spatiotemporal distribution of oral and maxillofacial traumas resulting from violence against children and adolescents through geostatistical techniques. METHODS: This study was an ecological analysis of cases of trauma caused by violence against Brazilian children and adolescents using aggregated data from victims attended at a Center of Forensic Medicine and Forensic Dentistry between January 2012 and December 2015. Data were analysed through modelling based on geographic information system (GIS). RESULTS: Two distinct patterns of longitudinal trajectory of oral and maxillofacial trauma related to violence against children and adolescents were identified (TP1 and TP2, P < 0.05). The spatial regression analysis revealed a statistically significant association between higher incidence of cases and areas with worse socioeconomic conditions (ß = 0.047, SE = 0.020, P < 0.05). CONCLUSION: Neighbourhoods with considerable socio-spatial vulnerability for violence against children and adolescents and maxillofacial traumas were identified.

Temporal trends in physical violence, gender differences and spatial vulnerability of the location of victim's residences.

The aim of study was to describe trends in physical violence among Brazilian victims and investigate spatial vulnerability of the location of victim's residences. This study performed an ecological-level longitudinal analysis, examining violence rates over 4 years. Cases of 4795 victims of physical aggression attended at a Center of Legal Medicine were investigated. Trend analysis was used to evaluate the data, with the creation of polynomial regression models (p < 0.05). Violence rates showed significant temporal variations according to sociodemographic characteristics of victims (p < 0.05) and the circumstances of aggressions (p < 0.05). Moreover, there was a significant increase in violence rate in the North (R2 = 16.1%; p = 0.019) and South (R2 = 18.4%; p = 0.010), whereas the rural zone (R2 = 10.1%; p = 0.028) presented a decrease. The findings highlight the need for protection policies that address spatial-temporal aspects.

Tomada de decisão de estudantes frente a um case scenario de Endodontia / Students' decision-making in the face of an endodontic case scenario

O presente estudo do tipo transversal avalia o processo de tomada de decisão de estudantes do 4º e 5º anos do curso de Odontologia de uma universidade pública da região Nordeste, frente a um case scenario de Endodontia. A amostra foi constituída por 80 estudantes, os quais, frente ao cenário descrito e imagem radiográfica apresentada, responderam a um questionário sobre o provável motivo da rarefação, a conduta clínica e a tomada de decisão. Para análise dos dados, foram obtidas distribuições absolutas, percentuais uni e bivariadas. A maioria dos pesquisados foi do sexo feminino (55,0%). Analisando a provável causa da rarefação periapical, 43,8% dos entrevistados acreditam que se deva ao limite apical de obturação. A anamnese, o exame clínico e a radiografia foram mencionados como os meios semiotécnicos indicados para a tomada de decisão de tratamento no caso apresentado por 95% dos estudantes. A maioria (60%) decidiu pelo retratamento endodôntico utilizando medicação intracanal. Conclui-se que os estudantes consideram o limite apical de obturação indesejável como motivo da rarefação apical; que a anamnese, exame clínico, exame radiográfico são indicados para a tomada de decisão e optaram pelo retratamento endodôntico. Os estudantes do 5º ano, com mais vivência clínica que os do 4º, apresentaram decisão terapêutica mais conservadora (AU).

This cross-sectional study evaluates the decisionmaking process of students in the 4th and 5th years of the Dentistry course of a public university in the Northeast region, facing a case scenario of Endodontics. The sample consisted of 80 students, who, in view of the described scenario and radiographic image presented, answered a questionnaire about the probable reason for rarefaction, clinical conduct and decision making. For data analysis, absolute distributions, uni, and bivariate percentages were obtained. The majority of respondents were female (55.0%). Analyzing the probable cause of periapical rarefaction, 43.8% of respondents believe that it is due to the apical limit of obturation. Anamnesis, clinical examination, and radiography were mentioned by 95% of the students as the means indicated for the treatment decision-making in the case presented. The majority (60%) decided for endodontic retreatment using intracanal medication. It is concluded that the students consider the undesirable apical limit of obturation as a reason for apical rarefaction; that anamnesis, clinical examination, radiographic examination are indicated for decision making and have chosen endodontic retreatment. The students of the 5th year, with more clinical experience than those of the 4th, presented a more conservative therapeutic decision (AU).

Intimate partner violence against women, circumstances of aggressions and oral-maxillofacial traumas: A medical-legal and forensic approach.

INTRODUCTION: Intimate partner violence (IPV) is a serious public health problem that frequently results in oral-maxillofacial traumas, generating high social and economic costs. The aim of this study was to describe the profile of women victims of IPV and determine the pattern of oral-maxillofacial traumas, according to a medical-legal and forensic perspective. An exploratory study of 1361 suspected cases of women victims of IPV was carried out based on database of an Institute of Legal Medicine and Forensic Dentistry of Northeastern Brazil during a period of 4 years. Medico-legal and social records of victims were searched for information related to sociodemographic data, circumstances of aggressions and trauma patterns. Descriptive and multivariate statistics and Multiple Correspondence Analysis (MCA) were performed. MAIN RESULTS: Almost half of victims exhibited some oral-maxillofacial trauma resulting from IPV (45.8%). Lesions affecting more than one third of the face (41.3%), especially in soft tissues (96.1%) were the most common. Based on the MCA results, two distinct victimization profiles (P1 and P2) have been identified. P1 was mainly characterized by women aged less than 28 years, living in the urban area, with higher education and working. They were assaulted using physical force in community settings perpetrated by former partner or ex-boyfriend during the night and weekends, resulting in oral-maxillofacial traumas. P2 was mainly composed of women aged over 28 years, living in the suburban or rural areas, with low schooling and who did not work. They were assaulted by firearm or weapon in their own home, perpetrated by their partner or boyfriend during the day and weekdays, resulting in trauma to other body parts. CONCLUSIONS: Oral and maxillofacial traumas are very common among women victims of IPV who searched for medical-legal service. In this context, forensic dentists can play a key role during the diagnostic process and should always work together with medical, biochemical and toxicological experts. The findings of this study may contribute to the formulation of evidence-based policies.

Maxillofacial trauma, etiology and profile of patients: an exploratory study / Traumas maxilofaciais, etiologia e perfil dos pacientes: um estudo exploratório

ABSTRACT Objective: To describe the profile of patients with facial trauma admitted in a hospital located in a metropolitan area of Northeast Brazil. Methods: A cross-sectional and exploratory study was performed. A total of 244 cases were in agreement with the eligibility criteria. The variables include the sociodemographic characteristics of patients, etiology, type of trauma, treatment modalities, length of stay in a hospital and quarter of care. Descriptive statistics and Cluster Analysis were performed. Results: The average age of patients was 31.16 years (SD = 15.17 years) and average hospitalization was 6.32 days (SD = 7.75 days). It was verified the automatic formation of four clusters with different profiles of patients. The variables which most contributed to the external differentiation between clusters were: length of stay in a hospital (p <0.001), etiology (p <0.001), type of facial trauma (p <0.001), presence of associated trauma (p <0.001), treatment modalities (p <0.001) and quarter of care (p <0.001). Conclusion: The most of patients were men, victims of traffic accidents, which suffered fracture of zygomatic complex and underwent surgery. Level of Evidence III, Retrospective Study.

Interpersonal violence, circumstances of aggressions and patterns of maxillofacial injuries in the metropolitan area of Campina Grande, State of Paraíba, Brazil (2008-2011). / Violência interpessoal, circunstâncias das agressões e padrões dos traumas maxilofaciais na região metropolitana de Campina Grande, Paraíba, Brasil (2008-2011).

The aim of this study was to determine the circumstances of aggressions and patterns of maxillofacial injuries among victims of interpersonal violence. This was a cross-sectional and exploratory study conducted from the analysis of 7,132 medical-legal and social records of interpersonal violence victims seen in a Forensic Medicine and Dentistry Center. Descriptive and multivariate statistics were performed using Multiple Correspondence Analysis. Three groups with different victimization profiles were identified. The first group was mainly composed of men of different age groups, victims of community violence that resulted in facial bones or dentoalveolar fracture. The second group was mainly composed of adolescents (10-19 years) of both sexes, victims of interpersonal violence and without specific pattern of injuries. The third group was composed of adult women (≥ 20 years) victims of domestic violence that resulted in injuries of soft tissues of face or other body regions. The results suggest that sociodemographic and circumstantial characteristics are important factors in victimization by maxillofacial injuries and interpersonal violence.

RESUMO O objetivo deste estudo foi determinar as circunstâncias das agressões e os padrões dos traumas maxilofaciais entre vítimas de violência interpessoal. Tratou-se de um estudo transversal e exploratório feito a partir da análise de 7.132 registros médico-legais e sociais de vítimas de violência interpessoal atendidas em um Centro de Medicina Legal e Odontologia Forense. Foi feita estatística descritiva e multivariada, usando Análise de Correspondência Múltipla. Três grupos com perfis distintos de vitimização foram identificados. O primeiro grupo foi formado majoritariamente por homens, de diferentes faixas etárias, vítimas de violência comunitária, resultando em fratura de ossos faciais ou fratura dentoalveolar. O segundo grupo foi composto essencialmente por adolescentes (10-19 anos), de ambos os sexos, vítimas de violência interpessoal e que não apresentaram um padrão específico de trauma. O terceiro grupo reuniu mulheres, adultas (≥ 20 anos), vítimas de violência doméstica, resultando em lesão de tecidos moles da face ou em outras regiões do corpo. Os resultados sugerem que as características sociodemográficas e circunstanciais são fatores importantes na vitimização por traumatismo maxilofacial e violência interpessoal.

Pattern of oral-maxillofacial trauma from violence against women and its associated factors.

BACKGROUND/AIM: Violence against women is a global public health problem. The aim of this study was to characterize the profile of women victims of violence and identify factors associated with maxillofacial injuries. MATERIAL AND METHODS: A cross-sectional study was performed based on an evaluation of 884 medico-legal and social records of women victims of physical aggression treated at the Center of Forensic Medicine and Dentistry in Brazil. The variables investigated were related to the sociodemographic characteristics of victims, circumstances of aggressions, and patterns of trauma. Descriptive and multivariate statistics using decision tree analysis by the Chi-squared automatic interaction detector (CHAID) algorithm, as well as univariate and multivariate Poisson regression analyses were performed. RESULTS: The occurrence of maxillofacial trauma was 46.4%. The mean age of victims was 29.38 (SD=12.55 years). Based on decision tree, the profile of violence against women can be explained by the aggressor's gender (P<.001) and sociodemographic characteristics of victims, such as marital status (P=.001), place of residence (P=.019), and educational level (P=.014). Based on the final Poisson regression model, women living in suburban areas were more likely to suffer maxillofacial trauma (PR=1.752; CI 95%=1.153-2.662; P=.009) compared to those living in rural areas. Moreover, aggression using a weapon resulted in a lower occurrence of maxillofacial trauma (PR=0.476; CI 95%=0.284-0.799; P=.005) compared to cases of aggression using physical force. CONCLUSIONS: The prevalence of oral-maxillofacial trauma was high, and the main associated factors were place of residence and mechanism of aggression.

OBJETIVO: Traçar o perfil dos pacientes internados com trauma de face em um hospital localizado em região metropolitana do Nordeste do Brasil. MÉTODOS: Tratou-se de estudo transversal e exploratório. Um total de 244 casos atendeu aos critérios de elegibilidade, sendo incluídos na amostra. As variáveis estudadas incluíram características sociodemográficas das vítimas, etiologia, tipos de traumas, modalidades de tratamento, tempo de internação e trimestre de atendimento. Foi feita estatística descritiva e análise de cluster. RESULTADOS: A média de idade dos pacientes foi 31,16 anos (DP = 15,17 anos) e o tempo médio de internação foi de 6,32 dias (DP = 7,75 dias). Verificou-se a formação automática de quatro clusters com perfis distintos de pacientes. As variáveis que mais contribuíram para a diferenciação externa entre os clusters foram: tempo de internação (p < 0,001), etiologia (p < 0,001), tipo do trauma facial (p < 0,001), presença de trauma associado (p < 0,001), tipo de tratamento (p < 0,001) e trimestre de atendimento (p < 0,001). CONCLUSÃO: A maioria dos pacientes eram homens, vítimas de acidentes de trânsito, que apresentaram fratura do complexo zigomático, submetidos a tratamento cirúrgico. Nível de Evidência III, Estudo Retrospectivo.

Violência contra mulheres em diferentes estágios do ciclo de vida no Brasil: um estudo exploratório / Violence against women in different stages of the life cycle in Brazil: an exploratory study

RESUMO: Objetivo: Descrever o perfil da violência contra mulheres em diferentes ciclos de vida, de acordo com as características sociodemográficas das vítimas e dos agressores. Métodos: Estudo transversal e exploratório realizado com base em 1.388 registros de ocorrências, durante período de quatro anos, em uma região metropolitana do Nordeste do Brasil. A variável dependente foi o tipo de agressão sofrido pelas vítimas. As variáveis independentes foram as características sociodemográficas das vítimas e dos agressores. A análise estatística incluiu o teste χ2 (p < 0,05) e a análise de árvore de decisão, por meio do algoritmo Chi-squared Automatic Interaction Detector (CHAID). Resultados: Os casos de agressão física (n = 644) foram os mais comuns, seguidos de ameaça (n = 415) e agressão verbal (n = 285). Os perfis da violência puderam ser explicados pela relação entre vítimas e agressores (p < 0,001) e faixa etária das vítimas (p = 0,026 em Nó 1; p = 0,019 em Nó 3). Conclusão: Foi observado que mulheres em diferentes fases da vida apresentam mais exposição a diferentes tipos de violência.

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 cross-sectional 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 χ2 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.

Facial trauma among victims of terrestrial transport accidents / Traumas faciais entre vítimas de acidentes de transporte terrestre

ABSTRACT INTRODUCTION: In developing countries, terrestrial transport accidents - TTA, especially those involving automobiles and motorcycles - are a major cause of facial trauma, surpassing urban violence. OBJECTIVE: This cross-sectional census study attempted to determine facial trauma occurrence with terrestrial transport accidents etiology, involving cars, motorcycles, or accidents with pedestrians in the northeastern region of Brazil, and examine victims' socio-demographic characteristics. METHODS: Morbidity data from forensic service reports of victims who sought care from January to December 2012 were analyzed. RESULTS: Altogether, 2379 reports were evaluated, of which 673 were related to terrestrial transport accidents and 103 involved facial trauma. Three previously trained and calibrated researchers collected data using a specific form. Facial trauma occurrence rate was 15.3% (n = 103). The most affected age group was 20-29 years (48.3%), and more men than women were affected (2.81:1). Motorcycles were involved in the majority of accidents resulting in facial trauma (66.3%). CONCLUSION: 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.

Resumo Introdução: Nos países em desenvolvimento, os acidentes de transporte terrestre (ATTs) são uma das principais causas de trauma facial, superando os casos de violência urbana, especialmente aqueles envolvendo automóveis e motocicletas. Objetivo: O objetivo deste estudo transversal censitário foi determinar a ocorrência de traumas faciais com etiologia de acidente de transporte terrestre (ATT): automóveis, motocicletas ou atropelamentos, em uma cidade do Nordeste do Brasil. Método: Foram analisados os dados de morbidade em laudos de um serviço forense de vítimas que procuraram o serviço de janeiro a dezembro de 2010. Resultados: Ao todo, foram avaliados 2.379 laudos; 673 eram referentes a ATTs, e 103 apresentaram traumas faciais. A coleta de dados foi realizada por três pesquisadores previamente treinados e calibrados, sendo elaborado um formulário específico para coleta das informações contidas nos laudos. Destes, 15,3% (n = 103) sofreram trauma facial. A faixa etária predominante para os eventos de trauma facial foi de 20-29 anos (48,3%), acometendo mais homens do que mulheres (2,81:1). A motocicleta foi o principal tipo de veículo com envolvimento de vítimas (66,3%). Conclusões: A ocorrência de traumas faciais em vítimas de acidente de transporte terrestreten de a afetar, em maior proporção, indivíduos homens e jovens, com maior prevalência para os acidentes envolvendo motocicletas.
