Resumen Introducción: El trauma es la segunda causa de mortalidad y la sexta de hospitalización en el país, siendo la violencia, los accidentes y las caídas las más prevalentes. Sin embargo, el país está experimentando reflejos de una pandemia de COVID-19, junto a una falta de estudios sobre el trauma, así como sobre la atención clínica. Objetivo: Analizar las características clínicas y epidemiológicas del trauma junto a la violencia, accidentes y caídas entre los años 2019, 2020 y 2021, considerados antes y durante la pandemia COVID-19. Materiales y métodos: Estudio de cohorte retrospectivo, con adultos de 25 a 55 años, que sufrieron trauma relacionado con violencia, caídas y otros accidentes, en el período comprendido entre marzo y junio de 2019, 2020 y 2021, en la ciudad de São Paulo. Las encuestas de datos fueron realizadas por el sistema TABNET, por el Departamento Municipal de Salud. Dentro de este sistema, la búsqueda se realizó a través del Sistema de Información para la Vigilancia de Accidentes, de la Coordinación de Vigilancia en Salud, en el cual las situaciones de violencia fueron notificadas y registradas por el Sistema Nacional de Información de Enfermedades Notificables. Posteriormente, se accedió al Sistema de Información de Vigilancia de Violencia y Accidentes, con enfoque en notificaciones y registro de caídas y otros accidentes. Resultados: El trauma siguió siendo más prevalente para los hombres, con educación primaria completa y raza predominantemente entre blancos y morenos. Al analizar los diferentes tipos de violencia: física, tortura y sexual, hubo mayores porcentajes de prevalencia durante el año 2019, período prepandémico de COVID-19, a excepción de la violencia psicológica / moral, que fue mayor en 2021. Nótese que los diferentes mecanismos de violencia fueron significativamente más prevalentes en 2019, así como las diferentes causas de violencia, caídas y traumatismos automovilísticos que involucran a peatones, ocupantes, conductores y pasajeros. La atención ambulatoria confirmó la tendencia de superioridad en el período prepandémico, sin embargo, la atención hospitalaria de emergencia mostró un mayor número de solicitudes en 2020 y 2021. Conclusión: Los traumas de violencia, accidentes y caídas son más prepandémico en comparación con el período durante la pandemia COVID-19; así como la búsqueda de asistencia sanitaria en hospitales y clínicas. Estos hallazgos muestran una posible reducción en los informes de trauma y una menor demanda de asistencia durante la pandemia.

Abstract Introduction: Trauma is the second leading cause of mortality and the sixth leading cause of hospitalization in the country, with violence, accidents, and falls being the most prevalent. However, the country is experiencing reflexes of the COVID-19 pandemic, together with a lack of studies on trauma, as well as on clinical care. Objective: To analyze the clinical and epidemiological characteristics of trauma related to violence, accidents, and falls among the years 2019, 2020, and 2021, considered as before and during the COVID-19 pandemic. Material and Methods: Retrospective cohort study, with adults aged 25-55 years, who suffered trauma related to violence, falls, and other accidents, in the period between March and June of 2019, 2020, and 2021, in the city of São Paulo. Data surveys were carried out using the TABNET system, of the Municipal Health Department. Within this system, the search was carried out through the Information System for the Surveillance of Accidents, of the Coordination of Health Surveillance, in which situations of violence were notified and recorded by the National Information System for Notifiable Diseases. Subsequently, the Information System for Surveillance of Violence and Accidents was accessed, focusing on notifications and records of falls and other accidents. Results: Trauma remained more prevalent for males, with complete primary education, and ethnicity predominantly between white or brown. When analyzing the different types of violence: physical, torture, and sexual, there was a prevalence of higher percentages during the year 2019, the pre-pandemic period of COVID-19, except for psychological/moral violence, which was higher in 2021. It should also be noted that the different mechanisms of violence were significantly more prevalent in 2019, as well as the different causes of violence, falls, and car trauma involving pedestrians, occupants, drivers, and passengers. Outpatient care confirmed the higher trend in the pre-pandemic period; however, emergency hospital care showed a greater number of requests in 2020 and 2021. Conclusión: Trauma from violence, accidents, and falls was higher pre-pandemic compared to the period during the COVID-19 pandemic; as well as the search for health care in hospitals and outpatient clinics. These findings show a possible reduction in trauma reports and lower demand for assistance during the pandemic.

Resumen Introducción: Los homicidios son causas importantes de mortalidad en el mundo, especialmente en Brasil, que representa aproximadamente dos tercios de las muertes por causas externas y el tercer lugar entre las causas de muerte en el país. Materiales Y métodos: Estudio retrospectivo sobre la ocurrencia de causas de muertes violentas ocurridas en diferentes regiones de Municipio de São Paulo de 2000 a 2014 según el Sistema de Información de Mortalidad de la Secretaría de Salud Municipal. Se calculó el coeficiente estandarizado (CP) para la ocurrencia de homicidios y las tasas de riesgo según la población y el sexo masculino. Resultados: De 11.981 casos, el CP mostró que las regiones sur y este mostraron un aumento en la ocurrencia de homicidios entre los años 2000 y 2005 en comparación con los años 2010 y 2014. Considerando la suma del CP en los 15 años, Es posible observar la mayor ocurrencia de homicidios en las regiones sur y oriente de la ciudad de São Paulo, sin embargo, con una reducción entre los años 2010 y 2014. En cuanto a la tasa de riesgo relativo de homicidio, la región norte tuvo tasas más altas entre 2000 y 2005. Al considerar el género masculino, la región oeste mostró un aumento en la tasa de riesgo entre 2000 y 2005. Para los años 2010 la tasa de riesgo se mantuvo elevada para las regiones: norte (1,14) y este (1,15), mientras que para los hombres la tasa de riesgo (0,91) se mantuvo alta para la región sur. En 2014, la tasa de riesgo más alta (1,18) se trasladó a la región occidental, mientras que para los hombres la tasa de riesgo más alta se dirigió a la región central (0,92). Conclusiones: Se mantuvieron altas tasas de ocurrencia de homicidios para las regiones sur y oriente de la ciudad de São Paulo durante los últimos 15 años. La tasa de riesgo difiere entre las regiones de la ciudad de São Paulo, destacando la región norte entre los años 2000, 2005 y 2010 y la región occidental en 2014. El género masculino influye en las tasas de riesgo entre regiones, especialmente la región occidental entre 2000 y 2005, la región sur en 2010 y la región central en 2014, mostrando su influencia en la ocurrencia de homicidios.

Abstract Introduction : Homicides are important causes of mortality in the world, especially in Brazil, which represents approximately two thirds of deaths from external causes and the third place among the causes of death in the country. Methods: Retrospective study on the occurrence of causes of violent deaths occurring in different regions of the city of São Paulo from 2000 to 2014 according to the Mortality Information System of the Municipal Health Secretariat. The standardized coefficient (CP) for the occurrence of homicides and risk rates according to population and male gender were calculated. Results: The PC showed that the south and east regions had increased homicide occurrence between 2000 and 2005 when compared to the years 2010 and 2014. Considering the sum of the PC over the 15 years can be observed the highest occurrence of homicide. in the southern and eastern regions of São Paulo, however, with a reduction in occurrence between 2010 and 2014. Regarding the relative risk rate for homicide, the northern region presented higher rates between 2000 and 2005. When considering gender male population, the western region showed an increase in the risk rate between 2000 and 2005. For 2010, the risk rate remained higher for the northern (1.14) and eastern (1.15) regions, while for the male gender. For men, the risk rate (0.91) remained high for the southern region. In 2014 the highest risk rate (1.18) moved to the western region while for males the highest risk rate was directed to the central region (0.92). Conclusions: High homicide rates have remained in the southern and eastern regions of the city of São Paulo over the past 15 years. The risk rate differs between the regions of the city of São Paulo, highlighting the northern region between 2000, 2005 and 2010 and the western region in 2014. The male gender influences the risk rates between the regions, especially the western region between 2000 and 2005, the southern region in 2010 and the central region in 2014, showing their influence on homicide.

RESUMO Objetivo: comparar o uso de solução alcoólica de clorexidina 0,5% e de álcool 70% na antissepsia da pele para bloqueios do neuroeixo. Método: ensaio clínico randomizado de não inferioridade, com dois braços paralelos. Foram selecionados 70 pacientes candidatos à bloqueio do neuroeixo, randomicamente alocados para o grupo A (n=35), em que a antissepsia foi realizada com clorexidina alcoólica 0,5%, ou para o grupo B (n=35), em que se utilizou álcool etílico hidratado 70%. Foram coletadas, com swab, amostras para cultura em três momentos: antes da antissepsia, dois minutos após aplicação do antisséptico, e imediatamente após a punção. As amostras foram semeadas em três meios de cultura e foi contabilizado o número de unidades formadoras de colônias (UFC) por cm². Resultados: não houve diferença entre os grupos quanto à idade, ao sexo, ao índice de massa corporal, ao tempo para realização do bloqueio ou tipo de bloqueio. Também não houve diferenças entre os grupos na contagem de UFC/cm² antes da antissepsia. Constatou-se menor crescimento bacteriano no grupo B dois minutos após aplicação do antisséptico (p=0,048), mas não houve diferença entre os grupos quanto ao número de UFC/cm² ao final da punção. Conclusão: o álcool 70% mostrou-se mais efetivo em reduzir o número de UFC/cm² após dois minutos, e não houve diferença entre os dois grupos quanto à colonização da pele ao final do procedimento. Esses resultados sugerem que o álcool 70% pode ser opção para antissepsia da pele antes de bloqueios do neuroeixo. Registro ensaio clínico: ClinicalTrials.gov, NCT02833376.

ABSTRACT Objective: to compare the use of 0.5% alcoholic chlorhexidine and 70% alcohol in skin antisepsis for neuraxial blocks. Method: this is a non-inferiority randomized clinical trial, with two parallel arms. Seventy patients who were candidates for neuraxial block were randomly allocated to group A (n = 35), in whom antisepsis was performed with 0.5% alcoholic chlorhexidine, or to group B (n = 35), in whom we used 70% hydrated ethyl alcohol. Swabs were harvested for culture at three times: before antisepsis, two minutes after application of the antiseptic, and immediately after puncture. The samples were sown in three culture media and the number of colony forming units (CFU) per cm² was counted. Results: there was no difference between the groups regarding age, sex, body mass index, time to perform the block or type of block. There were no differences between groups in the CFU/cm² counts before antisepsis. There was less bacterial growth in group B two minutes after application of the antiseptic (p = 0.048), but there was no difference between the groups regarding the number of CFU/cm² at the end of the puncture. Conclusion: 70% alcohol was more effective in reducing the number of CFU/cm² after two minutes, and there was no difference between the two groups regarding skin colonization at the end of the procedure. These results suggest that 70% alcohol may be an option for skin antisepsis before neuraxial blocks. Trial registration: ClinicalTrials.gov, NCT02833376.

ABSTRACT BACKGROUND: Suicide is one of the leading causes of death worldwide, accounting for one million deaths annually. Greater understanding of the causal risk factors is needed, especially in large urban centers. OBJECTIVE: To ascertain the epidemiological profile and temporal trend of suicides over two decades and correlate prevalence with social indicators. DESIGN AND SETTING: Descriptive population-based longitudinal retrospective study conducted in the city of São Paulo, Brazil. METHODS: A temporal trend series for suicide mortality in this city was constructed based on data from the Ministry of Health’s mortality notification system, covering 2000-2017. It was analyzed using classic demographic variables relating to social factors. RESULTS: Suicide rates were high throughout this period, increasing from 4.6/100,000 inhabitants in the 2000s to 4.9/100,000 in 2017 (mean: 4.7/100,000). The increase in mortality was mainly due to increased male suicide, which went from 6.0/100,000 to the current 8.0/100,000. Other higher coefficients corresponded to social risk factors, such as being a young adult (25-44 years old), being more educated (eight years of schooling) and having white ethnicity (67.2%). Suicide was also twice as likely to occur at home (47.8%). CONCLUSION: High suicide rates were seen over the period 2000-2017, especially among young adults and males. High schooling levels and white ethnicity were risk factors. The home environment is the crucial arena for preventive action. One special aspect of primary prevention is the internet and especially social media, which provides a multitude of information for suicide prevention.

OBJECTIVES: Although child mortality has declined significantly in recent decades, the reduction of neonatal mortality remains a major challenge as neonatal mortality represents 2/3 of the mortality rate in this population. The objective of this study was to evaluate the utility of the Score for Neonatal Acute Physiology Perinatal Extension II (SNAP-PE II) score for evaluating the survival prognosis of newborns admitted to a neonatal intensive care unit (NICU). METHODS: The study design involved an observational cross-sectional retrospective collection, as well as a prospective component. The sample included all newborns admitted to the NICU validated by the SNAP-PE II tool from January 1 to December 31, 2014. RESULTS: A predominance of young mothers (25.4 years), underwent prenatal care (86.2%), however a considerable percentage (49.4%) of mothers received insufficient medical consultation (less than six consults during their pregnancy). A prevalence of male admissions (62.4%) were noted in the NICU. Premature (61.7%) and underweight (weight <2,500 grams) newborns were also prevalent. The SNAP-PE II score showed an association between the infants who were discharged from the neonatal unit and the non-survivors. An increased prevalence of low birth weight and hypothermia was noted in the group of non-survivors. The mean arterial pressure appears to be a significant risk factor in the newborn group that progressed to death. Hypothermia, mean arterial pressure, and birth weight were the most significant variables associated with death. CONCLUSION: The SNAP-PE II was a beneficial indicator of neonatal mortality. The prevention of prematurity and hypothermia by improving maternity care and newborn care can decisively influence neonatal mortality.

Abstract Purpose: To conduct a scope review of the experimental model described by Walker and Mason, by identifying and analyzing the details of the method. Methods: The authors searched Pubmed-Medline, Cochrane-Bireme and PEDro databases for articles published between January 2016 and December 2018, using the following search queries: burns, burn injuries, models animal, and animal experimentation. All articles whose authors used Walker and Mason's model - with or without changes to the method in Wistar rats - were included in this study. Results: The search identified 45 mentions of Walker and Mason's model; however, after reading each summary, 20 were excluded (of which 5 due to duplicity). The inconsistencies observed after the scope review were: water temperature, length of time of exposure of the experimental model's skin to water, extent of the burnt area, and the description of the thickness/depth of the injury. Conclusions: Reproducibility of a scientific method is the basis to prove the veracity of the observed results. Thus, it is necessary to have a greater number of publications that adopt a reproducible scientific method, for this review found inconsistencies in the description of Walker and Mason's model.

Resumo Objetivo: Verificar se a prevalência de demência difere entre viúvos e não viúvos, e analisar se há associação com características sociodemográficas e clínicas, bem como diferenças entre os sexos. Método: Estudo observacional transversal retrospectivo que analisou prontuários de pacientes atendidos em um ambulatório de Neurologia do Comportamento de 1999 a 2009 através de anamnese, exame físico e neurológico, Clinical Dementia Rating Scale (CDR) e Miniexame do Estado Mental (MEEM). Avaliou-se variáveis sociodemográficas (escolaridade e idade) e clínicas (idade e tempo do início dos sintomas, MEEM e CDR). As diferenças foram avaliadas pelo teste de Mann Whitney, admitindo-se p<0,05. Resultados: Dos 208 pacientes com diagnóstico de demência, 73 (35,1%) eram viúvos e 135 (64,9%) não viúvos. Os viúvos eram mais velhos que os não viúvos (p<0,001) quando foram diagnosticados com demência. Essa diferença na idade manteve-se comparando os sexos (p<0,001), mulheres viúvas e não viúvas (p<0,001) e homens viúvos e não viúvos (p<0,001). O tempo do início dos sintomas até o diagnóstico foi maior em homens viúvos quando comparado aos não viúvos [55,6 (±86,3) vs 43,4 (±44,8) meses] mas sem significância estatística. Os viúvos com demência tinham menor escolaridade, independente do sexo (p<0,05). Conclusão: A prevalência de demência diferiu entre viúvos e não viúvos, sendo maior nos não viúvos. Houve associação da viuvez com características clínicas e sociodemográficas com diferença entre os sexos. A perda do cônjuge pode gerar diferentes desfechos entre homens e mulheres, necessitando de medidas com enfoque específico na prevenção e estratégias de cuidado na demência.

Abstract Objective: to verify if the prevalence of dementia differs between widowed and non-widowed elderly persons and between genders, and to analyse if there is an association with sociodemographic and clinical characteristics. Method: a retrospective cross-sectional observational study of patients treated at a Behavioral Neurology outpatient clinic from 1999 to 2009 was carried out, employing anamnesis, physical and neurological examination, the Clinical Dementia Rating Scale (CDR) and the Mini Mental State Examination (MMSE). Sociodemographic (schooling and age) and clinical (age of onset of symptoms and time since onset of symptoms, MMSE and CDR) variables were analyzed. The differences were evaluated by the Mann Whitney test, using a significance value of p<0.05. Results: of 208 patients diagnosed with dementia, 73 (35.1%) were widowed and 135 (64.9%) were non-widowed. Those who were widowed were older than those who were non-widowed (p<0.001) when diagnosed with dementia. This difference in age remained when gender (p<0.001), widowed and widowed women (p<0.001) and widowed and non-widowed men (p<0.001) were compared. The time from onset of symptoms to diagnosis was greater in widowed than in non-widowed men [55.6 (± 86.3) vs. 43.4 (± 44.8) months], although the difference was not statistically significant. Widowed patients with dementia had lower schooling, regardless of gender (p<0.05). Conclusion: the prevalence of dementia differed between widowed and non-widowed individuals, being higher among non-widows. There was an association between widowhood and the clinical and sociodemographic characteristics, with differences between the genders. The loss of a spouse can generate different outcomes among men and women, necessitating measures with a specific focus on prevention and strategies of care in dementia.

OBJECTIVE: To assess work ability and productivity in patients with diabetic foot. METHODS: This investigation was a cross-sectional controlled study. A total of 117 individuals were selected from March to June 2014 and allocated to group A (patients without diabetes, n=43), group B (diabetes patients without foot ulcers, n=43), or group C (patients with diabetic foot, n=31). Two validated instruments, the Work Limitations Questionnaire (WLQ) and the Work Productivity and Activity Impairment Questionnaire General Health v2.0 (WPAI-GH), were used to assess work ability and productivity. RESULTS: The groups were homogeneous regarding age and sex; however, patients in group C had a lower education level than the other participants (p=0.006). The median WLQ scores for groups A, B, and C were 0.0121, 0.0146, and 0.0852, respectively (p<0.0001). The WPAI-GH scores revealed a mean productivity loss of 20% for groups A and B and 100% for group C (p<0.0001). CONCLUSIONS: Patients with diabetic foot showed decreased work ability and productivity.

RESUMO Objetivo: avaliar a acurácia da ultrassonografia no diagnóstico de hérnia inguinal no pré-operatório de pacientes submetidos à herniorrafia inguinal. Métodos: estudo retrospectivo descritivo, analítico, baseado em dados obtidos dos prontuários de pacientes submetidos à herniorrafia inguinal entre janeiro de 2016 e dezembro de 2017 e que realizaram ultrassonografia no período pré-operatório. A amostra foi composta por 232 pacientes e foram comparados os resultados da ultrassonografia com as queixas, exame físico e achados intraoperatórios desses pacientes. Resultados: a ultrassonografia apresentou concordância com a queixa de hérnia inguinal em 52% dos pacientes (p=0,019). Houve discordância entre a porcentagem de pacientes que apresentaram hérnia ao exame físico não confirmada pelo exame ultrassonográfico (28,57%) e a porcentagem de hérnias identificadas somente ao exame complementar (8,93%), com significância estatística (p=0,0291). Quando comparados os resultados ultrassonográficos com achados intraoperatórios, 32,70% dos pacientes que apresentavam hérnia tinham ultrassonografia normal com significância estatística para discordância (p=0,001). Conclusão: a ultrassonografia mostrou-se método não confiável para auxiliar no diagnóstico em casos duvidosos de hérnia inguinal e dispensável quando o diagnóstico era confirmado por queixas típicas e exame físico compatível.

ABSTRACT Objective: to evaluate the accuracy of ultrasonography in the diagnosis of inguinal hernia in the preoperative period of patients submitted to inguinal herniorrhaphy. Methods: we conducted a retrospective, descriptive, analytical study, based on data obtained from the charts of patients submitted to inguinal herniorrhaphy between January 2016 and December 2017 and who underwent ultrasonography in the preoperative period. The sample consisted of 232 patients, and we compared the results of the ultrasonography with the complaints, physical examination and intraoperative findings. Results: ultrasonography was in agreement with inguinal hernia complaint in 52% of patients (p=0.019). There was a disagreement between the percentage of patients who presented a hernia at the physical examination not confirmed by the ultrasound examination (28.57%) and the percentage of hernias identified only by the complementary examination (8.93%), with statistical significance (p=0.0291). When comparing the ultrasound findings with the intraoperative ones, 32.70% of patients presenting with hernia had normal ultrasonography, with statistical significance for discordance (p=0.001). Conclusion: ultrasound was an unreliable method to help diagnosis in dubious cases of inguinal hernia, and dispensable when the diagnosis was confirmed by typical complaints and compatible physical examination.

ABSTRACT BACKGROUND: Breast cancer is the second most frequent type of cancer worldwide and the most common type among women. The treatment for this condition has evolved over recent decades with therapeutic and technological advances. Breast reconstruction techniques using musculocutaneous flaps from the latissimus dorsi and rectus abdominis have aroused interest regarding patients’ quality of life. Our goal here was to compare patients’ satisfaction scores after they underwent breast reconstruction using musculocutaneous flaps from either the latissimus dorsi or the rectus abdominis. DESIGN AND SETTING: Primary, clinical, analytical, observational and cross-sectional study conducted in a federal university and a public hospital. METHODS: Demographic and clinical data were collected. The Mini-Mental State Examination was then applied, with testing for specificity and sensitivity. Lastly, a breast evaluation questionnaire was applied to evaluate breast satisfaction among 90 women, who were divided into three groups: mastectomy (control; n = 30); breast reconstruction using flap from the latissimus dorsi (n = 30); and reconstruction using flap from the rectus abdominis (n = 30). RESULTS: The groups were homogeneous regarding the main demographic data and the questionnaire responses (P < 0.05). Compared with the control group, the reconstruction groups showed significant improvement in satisfaction (P < 0.0002) after one year. CONCLUSION: Within our sample, women who underwent breast reconstruction with flaps from either the latissimus dorsi or the rectus abdominis had similar satisfaction scores.

Resumo Introdução: Os pacientes cirúrgicos otorrinolaringológicos portadores da síndrome da apneia obstrutiva do sono apresentam, além de obstáculos anatômicos, tendência ao colapso das vias aéreas superiores. Síndrome da apneia obstrutiva do sono está relacionada ao maior risco de via aérea difícil e também aumento de complicações perioperatórias. A fim de se identificar esses pacientes no período pré-operatório, tem se destacado o questionário STOP Bang, por ser resumido e de fácil aplicação. Objetivos: Avaliar se pacientes submetidos à cirurgia otorrinolaringológica com diagnóstico de síndrome da apneia obstrutiva do sono pelo questionário STOP Bang apresentariam maior risco de complicações, particularmente ocorrência de via aérea difícil. Casuística e métodos: Feitas medidas de parâmetros anatômicos para via aérea difícil e administrado questionário para predição clínica de síndrome da apneia obstrutiva do sono em 48 pacientes com estudo polissonográfico prévio. Resultados: A amostra detectou via aérea difícil em 18,7% dos pacientes, todos portadores de síndrome da apneia obstrutiva do sono. Esse grupo apresentava maior idade, circunferência cervical > 40 cm, ASA II e Cormack III/IV. Os pacientes com síndrome da apneia obstrutiva do sono apresentaram maior índice de massa corpórea, circunferência cervical e frequência de apneia observada. Na análise de subgrupos, o grupo com síndrome da apneia obstrutiva do sono acentuada mostrou significantemente maior pontuação no SB quando comparado com pacientes sem síndrome da apneia obstrutiva do sono ou com síndrome da apneia obstrutiva do sono leve/moderada. Conclusões: O questionário STOP Bang não foi capaz de predizer via aérea difícil e nem síndrome da apneia obstrutiva do sono leve e moderada, mas identificou síndrome da apneia obstrutiva do sono acentuada. Todos pacientes com via aérea difícil apresentaram síndrome da apneia obstrutiva do sono moderada e acentuada, apesar desta síndrome não implicar em via aérea difícil. As variáveis Cormack III/IV e IMC maior do que 35 Kg.m-2 foram capazes de predizer via aérea difícil e síndrome da apneia obstrutiva do sono respectivamente.

Abstract Introduction: ENT patients with obstructive sleep apnea syndrome have a tendency of collapsing the upper airways in addition to anatomical obstacles. Obstructive sleep apnea syndrome is related to the increased risk of difficult airway and also increased perioperative complications. In order to identify these patients in the preoperative period, the STOP Bang questionnaire has been highlighted because it is summarized and easy to apply. Objectives: Evaluate through the STOP Bang questionnaire whether patients undergoing ENT surgery with a diagnosis of obstructive sleep apnea syndrome have a higher risk of complications, particularly the occurrence of difficult airway. Casuistry and methods: Measurements of anatomical parameters for difficult airway and questionnaire application for clinical prediction of obstructive sleep apnea syndrome were performed in 48 patients with a previous polysomnographic study. Results: The sample detected difficult airway in about 18.7% of patients, all of them with obstructive sleep apnea syndrome. This group had older age, cervical circumference > 40 cm, ASA II and Cormack III/IV. Patients with obstructive sleep apnea syndrome had higher body mass index, cervical circumference, and frequent apnea. In subgroup analysis, the group with severe obstructive sleep apnea syndrome showed a significantly higher SB score compared to patients without this syndrome or with a mild/moderate obstructive sleep apnea syndrome. Conclusions: The STOP Bang questionnaire was not able to predict difficult airway and mild obstructive sleep apnea syndrome, but it identified marked obstructive sleep apnea syndrome. All patients with difficult airway had moderate and marked obstructive sleep apnea syndrome, although this syndrome did not involve difficult airway. The variables Cormack III/IV and BMI greater than 35 kg.m−2 were able to predict difficult airway and obstructive sleep apnea syndrome, respectively.

OBJECTIVE: The aim of this study was to analyse patient-reported outcomes of reduction mammoplasty among Brazilian women. METHODS: A total of 100 women were enrolled in this cross-sectional controlled study, 50 with breast hypertrophy (Hypertrophy Group) and 50 who had undergone breast reduction at least six and up to 12 months before (Mammoplasty Group). The Brazilian version of the BREAST-Q® was applied to assess patient-reported outcomes. The module reduction/mastopexy was used, and the preoperative and postoperative versions were applied to the hypertrophy and mammoplasty groups, respectively. RESULTS: The mammoplasty group presented higher scores for the subscales satisfaction with breasts, psychosocial well-being, sexual well-being and physical well-being (p=0.0001 for all of these subscales). CONCLUSION: These results suggest that patients submitted to reduction mammoplasty are satisfied with the outcomes and present better quality of life scores compared with women with breast hypertrophy.

RESUMO Objetivo: identificar os principais fatores de risco associados ao desenvolvimento de complicações em pacientes portadores de apendicite aguda. Métodos: estudo caso controle de dados dos prontuários de 402 pacientes internados com apendicite aguda em um hospital de nível secundário, separados em dois grupos: grupo controle, com 373 pacientes que evoluíram sem complicações pós-operatórias (Grupo 1) e grupo estudo, com 29 pacientes que apresentaram complicações (Grupo 2). Foram avaliados dados demográficos, sinais e sintomas da doença, exames de imagem e dados da internação. Resultados: os fatores associados às complicações foram febre, alterações radiológicas e ultrassonográficas, descompressão brusca positiva e diarreia. Migração da dor, náuseas, vômitos e descompressão brusca positiva foram os achados significativamente mais frequentes nos dois grupos (p=0,05). Já a duração dos sinais e sintomas, em dias, no grupo 2 foi significativamente maior que no grupo 1, com mediana de três dias para o grupo com complicações (p=0,05). Conclusão: alterações nos exames de imagem, febre, diarreia, descompressão brusca positiva, tempo de duração de sintomas e menor faixa etária estão associados à maior frequência de complicações na apendicite aguda, o que reforça a importância da anamnese, do exame físico e da indicação de exames complementares na abordagem desses pacientes.

ABSTRACT Objective : to identify the main risk factors associated with the development of complications in patients with acute appendicitis. Methods: we conducted a case-control study of 402 patients with acute appendicitis hospitalized in a secondary hospital, divided into two groups: the control group, with 373 patients who progressed without postoperative complications (Group 1) and the study group, with 29 patients who presented complications (Group 2). We evaluated demographic data, signs and symptoms of the disease, imaging tests and hospitalization data. Results: factors associated with complications were fever, radiological and sonographic changes, abrupt positive decompression and diarrhea. Migration of pain, nausea, vomiting and abrupt positive decompression were the findings that were significantly more frequent in both groups (p = 0.05). The duration of signs and symptoms in days in group 2 was significantly higher than in group 1, with a median of three days for the group with complications (p = 0.05). Conclusion: alterations in imaging, fever, diarrhea, positive abrupt decompression, duration of symptoms and lower age are associated with a higher frequency of complications in acute appendicitis, which reinforces the importance of anamnesis, physical examination and indication of complementary exams in the approach of these patients.

RESUMO Objetivo: Avaliar e comparar o conhecimento de acadêmicos de odontologia sobre câncer bucal. Métodos: Os acadêmicos foram divididos em dois grupos, de acordo com o semestre cursado na graduação: Grupo A, primeiro semestre; e Grupo B: sétimo semestre. Eles foram convidados a responderem um questionário referente a epidemiologia, fatores de risco, aspectos clínicos, soluções terapêuticas e autoexame bucal. Para a análise estatística dos resultados, foram utilizados o teste exato de Fisher, o teste G de Cochran e o teste de concordância de Kendall, com nível de significância estabelecido em 0,05. Resultados: Somente 8,0% do Grupo A e 56,0% do Grupo B julgaram o sexo masculino como aquele frequentemente acometido pela lesão (p=0,0006). Em relação à faixa etária, 84,0% do Grupo B e 44,0% do Grupo A estimaram que a maioria dos casos era diagnosticada acima dos 40 anos (p=0,0072). O tabagismo foi apontado como principal fator de risco por 64,0% e 91,6% dos alunos dos Grupos A e B, respectivamente (p=0,0110). Nas questões referentes a sexo, etnia, faixa etária, fatores de risco, autoexame, tratamento, profissional responsável pelo tratamento e perfil de um indivíduo portador da lesão, os alunos do sétimo semestre apresentaram percentagens de respostas corretas significantemente maiores que as dos discentes do primeiro semestre. Conclusão: Houve significativa concordância entre os erros e acertos dos discentes do primeiro e sétimo semestres, sendo necessária uma abordagem específica direcionada à deficiência por eles apresentadas.

ABSTRACT Objective: To evaluate and compare the knowledge of dental undergraduate students about oral cancer. Methods: The students were divided into two groups according to semester attended in the undergraduate course: Group A, the first semester; and Group B, seventh semester. They were asked to answer a questionnaire about epidemiology, risk factors, clinical aspects, therapeutic solutions and oral self-examination. For statistical analysis, the Fisher's exact test, the Cochran's G test and Kendall's concordance test were used, with significance level set at 0.05. Results: Regarding the prevalent sex, only 8.0% of Group A and 56.0% of Group B judged males as the frequent affected by the disease (p=0.0006). In terms of age, 84.0% of the Group B and 44.0% of the Group A estimated that most cases were diagnosed over 40 years (p=0.0072). Smoking was identified as the major risk factor for 64.0% and 91.6% of Groups A and B, respectively (p=0.0110). On issues related to sex, ethnicity, age, risk factors, self-examination, treatment, professional responsible for treatment and profile of an individual with the disease, the seventh-semester showed significantly higher correct answer percentages than first-semester undergraduates. Conclusion: There was significant correlation between the right and wrong answers given by first and seventh semester students, making necessary a specific approach directed to their lack of knowledge.

RESUMO JUSTIFICATIVA E OBJETIVOS: Determinar a incidência de sinais e sintomas de disfunção temporomandibular (DTM) em pacientes de cirurgia eletiva submetidos à intubação orotraqueal. MÉTODOS: Estudo longitudinal controlado com dois grupos. O grupo de estudo incluiu pacientes que foram submetidos à intubação orotraqueal e um grupo controle. Usamos o questionário da Academia Americana de Dor Orofacial (AAOP) para avaliar os sinais e sintomas da DTM no primeiro dia de pós-operatório (T1) e os estados basais dos pacientes antes da cirurgia (T0) também foram registrados. O mesmo questionário foi usado após três meses (T2). A amplitude da abertura bucal foi medida em T1 e T2. Consideramos um valor p inferior a 0,05 como significativo. RESULTADOS: No total, 71 pacientes foram incluídos, com 38 pacientes no grupo de estudo e 33 no grupo controle. Não houve diferença significativa entre os grupos quanto à idade (grupo de estudo: 66 [52,5-72]; grupo controle: 54 [47-68], p = 0,117) ou gênero feminino (grupo de estudo: 57,9%; grupo controle: 63,6%, p = 0,621). No T1, não foram encontradas diferenças estatisticamente significativas entre os grupos quanto à incidência de limitação de abertura bucal (grupo de estudo: 23,7% vs. grupo controle: 18,2%, p = 0,570) ou amplitude de abertura bucal (grupo de estudo: 45 [40-47]vs. grupo controle: 46 [40-51], p = 0,278). Em T2, os resultados obtidos foram semelhantes. Não houve diferença significativa na resposta afirmativa a todas as perguntas individuais do questionário AAOP. CONCLUSÕES: Em nossa população, a incidência de sinais e sintomas de DTM de origem muscular não foi diferente entre os grupos.

ABSTRACT BACKGROUND AND OBJECTIVES: To determine the incidence of signs and symptoms of temporomandibular disorder in elective surgery patients who underwent orotracheal intubation. METHODS: This was a longitudinal controlled study with two groups. The study group included patients who underwent orotracheal intubation and a control group. We used the American Academy of Orofacial Pain questionnaire to assess the temporomandibular disorder signs and symptoms one-day postoperatively (T1), and the patients' baseline status prior to surgery (T0) was also recorded. The same questionnaire was used after three months (T2). The mouth opening amplitude was measured at T1 and T2. We considered a pvalue of less than 0.05 to be significant. RESULTS: We included 71 patients, with 38 in the study group and 33 in the control. There was no significant difference between the groups in age (study group: 66.0 [52.5-72.0]; control group: 54.0 [47.0-68.0]; p = 0.117) or in their belonging to the female gender (study group: 57.9%; control group: 63.6%; p = 0.621). At T1, there were no statistically significant differences between the groups in the incidence of mouth opening limitation (study group: 23.7% vs. control group: 18.2%;p = 0.570) or in the mouth opening amplitude (study group: 45.0 [40.0-47.0] vs. control group: 46.0 [40.0-51.0];p = 0.278). At T2 we obtained similar findings. There was no significant difference in the affirmative response to all the individual questions in the American Academy of Orofacial Pain questionnaire. CONCLUSIONS: In our population, the incidence of signs and symptoms of temporomandibular disorder of muscular origin was not different between the groups.
