RESUMO
OBJECTIVE: To identify the epidemiological profile of mandibular fractures in the emergency department. METHOD: Observational, retrospective study included records of persons with a diagnosis of mandibular fracture treated between January 1, 2015 and June 30, 2019, from the emergency department of the Hospital de Traumatología Dr. Victorio de la Fuente Narváez. The age, sex, occupation, comorbidities, prevalence of mandibular fractures according to the number of fractures and anatomical area, were obtained from the clinical records. RESULTS: 319 subjects with mandibular fractures were included in the study, which were young people (32.5 years) of the male sex (89.7%), the majority developed some trade (64.2%), 14.4% had some comorbidity, 76% had alcoholism when time of injury. The most affected anatomical site was the mandibular angle followed by the parasymphysis, the most frequent cause of injury was due to physical aggression. CONCLUSIONS: Mandibular fractures in our emergency department are usually simple, mainly affecting the angle of the jaw, occurring mainly in men in their third decade of life, assaults are the most frequent injury mechanism and are generally associated with substance use toxic.
OBJETIVO: Identificar el perfil epidemiológico de las fracturas mandibulares en el servicio de urgencias. MÉTODO: Estudio observacional, retrospectivo, en el que se incluyeron expedientes de derechohabientes con diagnóstico de fractura mandibular tratados entre el 1 de enero de 2015 y el 30 de junio de 2019 en el servicio de urgencias del Hospital de Traumatología Dr. Victorio de la Fuente Narváez. De los expedientes se obtuvieron la edad, el sexo, la ocupación, la comorbilidad, el antecedente de toxicomanías y la prevalencia de las fracturas mandibulares de acuerdo con el número de fracturas y la zona anatómica. RESULTADOS: Se incluyeron 319 sujetos con fracturas mandibulares, jóvenes (32.5 años), con predominio del sexo masculino (89.7%), la mayoría desarrollaba algún oficio (64.2%), el 14.4% con alguna comorbilidad y el 76% presentaba alcoholismo al momento de la lesión. El sitio anatómico más afectado fue el ángulo mandibular, seguido de la parasínfisis. La causa más frecuente de lesión fue por agresión física. CONCLUSIONES: Las fracturas mandibulares en nuestro servicio de urgencias suelen ser simples y afectar el ángulo de la mandíbula, presentándose principalmente en hombres en la tercera década de la vida. Las agresiones son el mecanismo de lesión mas frecuente y por lo general se asocian al consumo de sustancias tóxicas.

BACKGROUND: In patients with mucoepidermoid carcinoma (MEC) originating in salivary glands, because of the relative rarity of these tumors and the remarkable variability in their biological behavior, opinions differ about appropriate classification, grading, and treatment. OBJECTIVE: We undertook this study to analyze clinical and histological prognostic factors in a series of patients with MEC using univariate and multivariate survival analyses. METHODS: We reviewed 47 patients with MEC treated at our institution from 1985 to 2000. Clinical, epidemiological, treatment and follow-up data were obtained from medical records. All cases were histologically reviewed. The influence of prognostic factors on 5- and 10-year disease-specific survival was analyzed using Kaplan-Meier actuarial method and log-rank test. Cox regression tests were used to analyze the impact of the prognostic factors on survival. RESULTS: Females represented 59.6% of the patients. The major salivary glands were affected in 74.5%. Overall survival at 5 and 10 years was 78.3% and 69.3%, respectively. Disease-free survival at 5 years was 73.9% and at 10 years was 67.5%. Multivariate survival analysis revealed that tumor size (T4) (p = 0.0008), regional metastasis (p = 0.000), high histological grade (p = 0.0002), perineural invasion (p = 0.000), positive margin (p = 0.000), necrosis (p = 0.005), and intracystic component <20% (p = 0.0002) were all correlated with a poor prognosis. CONCLUSIONS: Clinical stage and histological grade are the main prognostic factors in mucoepidermoid carcinoma. Nevertheless, our univariate and multivariate analyses showed that other clinical and histological prognostic factors are independent significant indicators.
