RESUMO

Introdução: Os traumas abdominais representam notável importância dentre as causas predominantes de morbi-mortalidade no mundo. Em se tratando de óbitos relacionados a essas lesões, estão na categoria de causas externas, as quais no Brasil representam a segunda causa geral de mortalidade, principalmente na população em idade ativa. Notadamente, traumas estão fortemente relacionados a acidentes automobilísticos, cujas taxas vêm crescendo nos últimos anos. Neles, ocorrem os politraumas, cuja região abdominal é inclusa de forma prevalente. Objetivo: a presente pesquisa tem como objetivo apresentar o perfil de óbitos os quais sejam associados a trauma abdominal e submetido ao Instituto Médico-Legal, entre os anos de 2019 até 2021. Metodologia: estudo retrospectivo, do tipo transversal, de caráter fundamentalmente quantitativo, no qual foram avaliados os laudos de óbitos decorrentes de trauma abdominal necropsiados no IML de Toledo (PR), no período de 2019 a 2021. Foram avaliadas as variáveis sexo, idade, tipo de lesão, circunstância dos óbitos e órgão mais acometido. Resultados e discussão: dos 916 óbitos trazidos à Polícia Científica de Toledo (PR) advindos de causas externas, os inclusos dentre os traumas abdominais representaram um percentual de 51,05% (n=462), no período de 2019 a 2021. Observou-se maior prevalência de óbitos por acidentes automobilísticos (68,61%), cuja causa principal foi o politrauma (37,45%). O sexo masculino fora o mais prevalente, com 84,85% (n=392), cuja faixa etária teve concentração entre os 18 aos 29 anos. Os órgãos mais lesionados foram o fígado (69,31%) e o baço (33,66%). Considerações finais: nesta amostra houve predominância de óbitos por acidentes, principalmente associados ao trauma contuso, em homens na faixa entre 18 e 29 anos, cujo órgão mais lesado fora o fígado. O conhecimento acerca do perfil de óbitos é uma importante ferramenta epidemiológica frente a possíveis intervenções, além de servir como fonte estatística para outros trabalhos do âmbito médico-legal.

Introduction: Trauma represents a notable importance among the predominant causes of morbidity and mortality in the world. When it comes to deaths related to these injuries, they are in the category of external causes, since in Brazil they represent the second general cause of mortality, especially in the working-age population. Notably, traumas are strongly related to car accidents, whose rates have been increasing in recent years. In them, polytraumas occur, whose abdominal region is prevalently included. Objective: this research aims to present the profile of deaths which are associated with abdominal trauma and hospitalized at the Instituto Médico-Legal, between the years 2019 to 2021. Methodology: retrospective, cross-sectional study, fundamentally quantitative, in which the reports of deaths resulting from abdominal trauma necropsied at the IML of Toledo (PR), from 2019 to 2021, were evaluated. The variables were gender, age, type of injury, injuries of the deaths and most affected organ. Results and removal: Of the 916 deaths brought to the Scientific Police of Toledo (PR) from external causes, those included among abdominal traumas represented a percentage of 51.05% (n=462), in the period from 2019 to 2021. there was a higher prevalence of deaths from car accidents (68,61%), whose main cause was polytrauma (37.45%). Males were the most prevalent, with 84.85% (n=392), whose age group was concentrated between 18 and 29 years. The most injured organs were the liver (69.31%) and the spleen (33.66%). Final considerations: in this sample there was a predominance of deaths from accidents, mainly associated with blunt trauma, in men aged between 18 and 29 whose most injured organ outside the liver. Knowledge about the profile of deaths is an important epidemiological tool in the face of possible interventions, in addition to serving as a statistical source for other studies in the medical-legal field.

RESUMO

SUMMARY: Endometriosis, defined as the presence of endometrial glands and stroma outside the uterine cavity, is a chronic inflammatory condition that affects between 8 % and 44 % of women of reproductive age. Occasionally it presents as a sensitive mass in the abdominal wall, in relation to a surgical scar. On the other hand, in the most severe stage of endometriosis, intestinal involvement is common, and endometriotic disease of the appendix may be present even in appendices with macroscopically normal appearance. Simultaneous affectation of both locations is very rare. Nevertheless, treatment of choice is the excision of both lesions with safety margins. The aim of this manuscript was to report a case of simultaneous deep endometriosis affecting the total abdominal wall and vermiform appendix, resected in a single surgical procedure, which subsequently required abdominal wall repair with mesh plasty. Since desmoid tumors and endometriosis share similar clinical signs and unspecific imaging exams, both options should be considered in case of abdominal wall mass in female patients of childbearing age, especially if they have a history of uterine-related surgery.

La endometriosis se define como la presencia de glándulas endometriales y estroma fuera del útero. Es una afección crónica que afecta entre el 8 % y el 44 % de las mujeres en edad reproductiva. Ocasionalmente se presenta como una masa sensible en la pared abdominal, en relación con una cicatriz quirúrgica. Por otro lado, en su estadio más grave de la endometriosis, la afectación intestinal es común y puede afectar al apéndice, pudiendo estar presente incluso en apéndices de apariencia macroscópicamente normal. La afectación de ambas localizaciones simultáneamente es muy infrecuente. Sin embargo, el tratamiento de ambas lesiones es su exéresis quirúrgica con márgenes de seguridad. El objetivo de este manuscrito fue reportar un caso de endometriosis profunda simultánea que afectaba la pared abdominal total y el apéndice vermiforme, las que fueron resecadas en un solo tiempo quirúrgico, incluyendo posteriormente reparación de la pared abdominal con uso de malla. Dado que los tumores desmoides y la endometriosis comparten signos clínicos similares y exámenes de imágenes inespecíficos, se deben considerar ambas opciones en caso de masas en la pared abdominal de mujeres en edad fértil, especialmente si tienen antecedentes de cirugía relacionada con el útero.

RESUMO

Acute abdominal pathologies can cause electrocardiogram (ECG) changes mimicking an acute coronary syndrome (ACS), resulting in diagnostic uncertainty and delay. We report a 65-year-old male with multiple risk factors for ACS who presented with four hours of progressive epigastric and chest pain that resolved in the emergency department. ECG findings were concerning for new deeply inverted T-waves with normal troponins, raising concerns for Wellens Syndrome. Emergent heart catheterization was negative but abdominal computed tomography angiography showed occlusion of the superior mesenteric vessels. Subsequent exploratory laparotomy revealed a small bowel volvulus with extensive necrosis, resulting in a 430 cm resection.

RESUMO

An arcuate line hernia is a generally asymptomatic, ascending protrusion of intraperitoneal structures over the linea arcuata. Arcuate line herniae are scarcely reported in the literature. Only a few publications were found. No clear descriptions of the techniques for repair have been published either. We aim to provide diagnostic images and illustrate our method to repair this hernia.

RESUMO

We describe cases of intestinal failure wherein inpatient admission was critical toward enteral autonomy. We performed a retrospective chart review of 6 children with long-term parenteral nutrition dependence who were weaned from parenteral nutrition after admission. Admissions included feeding and medication titration, interdisciplinary care, and a home parenteral nutrition team consultation.

RESUMO

Introducción. Las complicaciones posteriores a la reparación endovascular de aneurisma (EVAR) pueden resolverse con técnicas endovasculares. Sin embargo, cuando está indicada, la explantación de una endoprótesis es un procedimiento complejo, que se asocia a lesiones vasculares o viscerales, con alta morbimortalidad, en pacientes con edad avanzada y múltiples comorbilidades, y por lo tanto, alto riesgo quirúrgico. No existen dispositivos producidos por la industria para explantar las endoprótesis aórticas, por lo que el objetivo de este trabajo fue desarrollar un dispositivo para la explantación de endoprótesis aórticas. Métodos. Se llevó a cabo un estudio experimental, en fase preclínica, para desarrollar un dispositivo para la explantación de endoprótesis aórticas, con pruebas en modelos 3D y en un modelo animal porcino cadavérico. Resultados. Es factible desarrollar un modelo experimental de un nuevo dispositivo para explantar endoprótesis aórticas, denominado explantador de Cabrera, y comprobar su funcionamiento en un modelo animal cadavérico. El uso del explantador de Cabrera limitó el daño de la pared aórtica por parte de la endoprótesis en un 100 % al momento de su explantación en un modelo experimental ex vivo. Conclusión. Usando una jeringa septo, el explantador de Cabrera es superior a la técnica estándar de explantación de una endoprótesis al limitar la lesión de la pared aórtica, al colapsar y liberar los ganchos de fijación suprarrenal de forma controlada y segura al interior de la luz aórtica y, posteriormente, extraerla de forma rápida y efectiva, conservando la mayor cantidad de aorta sana para la posterior reconstrucción aorto-ilíaca.

Introduction. Complications after endovascular aneurysm repair (EVAR) can be resolved with endovascular techniques; however, when indicated, stent explantation is a complex procedure, which is associated with vascular or visceral injuries, with high morbidity and mortality in patients, with advanced age and multiple comorbidities, and therefore high surgical risk. There are no devices produced by the industry to explant aortic endoprostheses, so the objective of this work was to develop a device for the explantation of aortic endoprostheses. Methods. An experimental study was carried out, in the preclinical phase, to develop a device for the explantation of aortic endoprostheses, with tests in 3D models and in a cadaveric porcine animal model. Results. It is feasible to develop an experimental model of a new device for explanting aortic endoprostheses, called Cabrera explanter, and verify its operation in a cadaveric animal model. The use of the Cabrera explanter limited damage to the aortic wall by the endoprosthesis by 100% at the time of explantation in an ex vivo experimental model. Conclusions. Using a septum syringe, the Cabrera explanter is superior to the standard stent explantation technique by limiting injury to the aortic wall, collapsing and releasing the adrenal fixation hooks in a controlled and safe manner into the aortic lumen, and subsequently, extract it quickly and effectively, preserving the greatest amount of healthy aorta for the subsequent aorto-iliac reconstruction.

RESUMO

Introducción. El síndrome de la arteria mesentérica superior, también conocido como síndrome de Wilkie, es una entidad infrecuente en la que una reducción del ángulo o espacio aorto-mesentérico determina una compresión extrínseca con obstrucción del tercio distal del duodeno, demostrando síntomas y signos característicos de obstrucción intestinal. El pilar del tratamiento es el manejo médico conservador con repleción nutricional, con el objetivo de aumentar el grosor de la grasa retroperitoneal y con esto resolver la compresión duodenal. Caso clínico. Paciente de 16 años, con un curso crónico marcado por dolor abdominal, estreñimiento, distensión, pirosis y pérdida de peso. Inicialmente se trató como una enfermedad ácido-péptica, con pobre mejoría, por lo que se realizaron estudios imagenológicos con lo que se documentó una disminución del ángulo aortomesentérico. Resultado. Se instauró un manejo médico con un protocolo de repleción nutricional por vía oral, para lograr ganancia de peso y evitar la cirugía. Conclusión. Con base a los síntomas y hallazgos en imágenes diagnósticas se hizo el diagnóstico de síndrome de la arteria mesentérica superior, que es una causa de obstrucción intestinal con muy baja incidencia. Su presentación clínica incluye gran variedad de síntomas, entre los que destaca el dolor abdominal y la pérdida de peso. Es frecuente la confusión con otras enfermedades más frecuentes, como enfermedad ácido-péptica, reflujo gastrointestinal y malabsorción. Su diagnóstico requiere un alto índice de sospecha, por lo que es importante conocer esta entidad y considerarla en el estudio de pacientes con los síntomas mencionados.

Introduction. Superior mesenteric artery syndrome, also known as Wilkie syndrome, is a rare entity in which a reduction in the aorto-mesenteric angle or space determines extrinsic compression with obstruction of the distal third of the duodenum, demonstrating characteristic symptoms and signs of intestinal obstruction. The mainstay of treatment is conservative medical management with nutritional repletion, with the aim of increasing the thickness of the retroperitoneal fat and thereby resolving duodenal compression. Clinical case. A 16-year-old patient, with a chronic course marked by abdominal pain, constipation, bloating, heartburn and weight loss. Initially was treated as an acid-peptic disease, with poor improvement. Imaging studies were performed, which documented a decrease in the aorto-mesenteric angle. Conclusion. Based on the symptoms and findings on diagnostic images, the diagnosis of superior mesenteric artery syndrome was made, which is a cause of intestinal obstruction with a very low incidence. Its clinical presentation includes a wide variety of symptoms, among which abdominal pain and weight loss stand out. Confusion with other more common diseases is common, such as acid-peptic disease, gastrointestinal reflux and malabsorption. Its diagnosis requires a high index of suspicion, so it is important to know this entity and consider it in the study of patients with the aforementioned symptoms.

RESUMO

El presente estudio es una comparación del dolor abdominal producido por trastornos gastrointestinales, aliviado por Ageratina ligustrina , entre los grupos maya Tzeltal, Tzotzil y Q ́eqchi ́, el cual integró un enfoque etnomédico, etnobotánico y transcultural, comparando estudios previos con el presente trabajo de campo. Para evaluar la eficacia de Ageratina para aliviar el dolor abdominal, se realizó un inventario de las moléculas reportadas en esta especie, así como de su actividad farmacológica, a través de una revisión bibliográfica. Los resultados mostraron que la epidemiología del dolor producido por TGI, su etnobotánica y el modelo explicativo del dolor abdominal fueron similares entre grupos étnicos. Asimismo, se identificaron 27 moléculas con efectos antiinflamatorios y antinociceptivos, lo que podría explicar por qué esta especie es culturalmente importante para los pobladores maya Tzeltal, Tzotzil y Q ́eqch i ́ para el alivio del dolor abdominal, mientras que, desde el punto de vista biomédico, es una especie con potencial para inhibir el dolor visceral.

The current study is a comparison of the abdominal pain conception produced by gastrointestinal disorders, relieved by Ageratina ligustrina , among inhabitants of the Mayan Tzeltal, Tzotzil, and Q'eqchi' groups ethnomedical, ethnobotanical, and cross -cultural approaches were used to compare previous studies with the present field work. To evaluate the efficacy of A. ligustrina to relieve pain, also through a bibliographic review an inventory of the molecules present in this species was performed, as well as their pharmacological activity. The results showed that the epidemiology of pain produced by GID, its ethnobotany, and the explanatory model of abdominal pain are similar among ethnic groups. Likewise, 27 molecules with anti-inflammatory and anti-nociceptive effects were identified, which could explain why this species is culturally important for the Mayan Tzeltal, Tzotzil, and Q'eqchi' groups for the relief of abdominal pain, while, from a biomedical point of view, it is a species with potential to inhibit visceral pain.

RESUMO

OBJECTIVE: To examine the relationship between the age-adjusted Charlson comorbidity index (A-CCI) with body composition and overall survival in patients newly diagnosed with colorectal cancer (CRC). RESEARCH METHODS AND PROCEDURES: In this cohort study, patients (≥ 18 years old) with CRC were followed for 36 months. Computed tomography images of the third lumbar were analyzed to determine body composition, including skeletal muscle area (SMA), skeletal muscle index (SMI), skeletal muscle radiodensity (SMD), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT). Phenotypes based on comorbidity burden assessed by A-CCI and body composition parameters were established. RESULTS: A total of 436 participants were included, 50% male, with a mean age of 61 ± 13.2 years. Approximately half of the patients (50.4%) had no comorbidity, and the A-CCI median score was 4 (interquartile range: 3-6). A higher A-CCI score was a risk factor for 36-month mortality (HR = 3.59, 95% CI = 2.17-5.95). Low SMA and low SMD were associated with a higher A-CCI. All abnormal phenotypes (high A-CCI and low SMA; high A-CCI and low SMD; high A-CCI and high VAT) were independently associated with higher 36-month mortality hazard (adjusted HR 5.12, 95% CI 2.73-9.57; adjusted HR 4.58, 95% CI 2.37-8.85; and adjusted HR 2.36, 95% CI 1.07-5.22, respectively). CONCLUSION: The coexistence of comorbidity burden and abnormal body composition phenotypes, such as alterations in muscle or fat compartments, may pose an additional risk of mortality in patients newly diagnosed with CRC. Early assessment and management of these phenotypes could be crucial in optimizing outcomes in such patients.

RESUMO

BACKGROUND: The leading cause of death in older people is cardiovascular diseases. Several studies have found that neck circumference (NC) is a simple anthropometric marker associated with adiposity. The aim of this study is to estimate and validate NC cut-off points as adiposity markers and analyze their association with cardiovascular and chronic metabolic diseases in older people. METHODS: A cross-sectional study in 358 non-disabled, community-dwelling older people (71.7 ± 3.9 years) living in Santiago de Chile and participating in the HTSMayor study was conducted. Measurements of body composition and cardiovascular risks were evaluated. Receiver operating characteristic (ROC) curves and multiple logistic regression models were used to evaluate the association of NC with cardiovascular and chronic metabolic diseases. NC cut-off points were obtained to predict obesity, abdominal obesity, and adiposity. RESULTS: The best performance values of neck circumference relative to obesity and adiposity were obtained with respect to abdominal obesity (40.6 cm in men and 34.2 cm in women). Higher NC values were associated with a higher area under the curve (AUC) for men and women (men: AUC = 0.84; women: AUC = 0.86). NC was significantly associated with a higher risk for diabetes mellitus (OR = 1.95), hypertension (OR = 2.42), acute myocardial infarction (OR = 4.36), and comorbidities (OR = 2.01), and a lower risk for sarcopenia (OR = 0.35). CONCLUSIONS: This study shows that NC is a useful tool for detecting abdominal obesity, obesity, and adiposity in older people and that a higher NC increases the risk of chronic diseases.
