RESUMO

En Colombia, para 2020, el cáncer de pulmón se reportó como la segunda neoplasia con mayor incidencia y la primera con mayor tasa de mortalidad según las cifras del minis-terio de salud de Colombia. El compromiso peritoneal en el cáncer de pulmón es algo extremadamente raro, se considera <1%. A continuación, exponemos un caso de car-cinomatosis peritoneal en cáncer de pulmón en un hospital en la ciudad de Bogotá. Se incorpora una posterior revisión descriptiva de la literatura de los casos clínicos de car-cinomatosis peritoneal en cáncer de pulmón reportados en la literatura mundial en los últimos 20 años, con el objetivo de resumir las principales características de estos pa-cientes que permiten plantear hipótesis de su enfoque terapéutico y pronóstico


In Colombia for 2020, lung cancer was reported as the fifth neoplasm with the highest incidence and the second with the highest mortality rate. Peritoneal involvement in lung cancer is extremely rare, it is considered <1%. Next, we present a case of peritoneal car-cinomatosis in lung cancer in Bogotá, with a subsequent literature review of the litera-ture of clinical cases of peritoneal carcinomatosis in lung cancer reported in the world li-terature in the last 20 years. The aim is to summarize the main characteristics of these patients that allow to hypothesize their prognostic and therapeutic approach

RESUMO

RESUMEN INTRODUCCIÓN: La COVID-19 se acompaña de eventos tromboembólicos venosos y arteriales en pacientes con historia de hipertensión y aterosclerosis. Se reporta el caso de una paciente joven y sin factores de riesgo cardiovascular que adquirió la infección por el SARS-COV2 y luego presentó un accidente cerebrovascular isquémico. CASO: Paciente de 44 años hospitalizada por la covid-19 en tratamiento protocolario con anticoagulación, esteroide y oxígeno suplementario. Al día 7 del inicio de los síntomas respiratorios presentó infarto cerebral por trombosis de arteria carótida derecha, arteria cerebral media derecha e izquierda y edema cerebral hemisférico derecho, tras lo cual fue diagnosticada con muerte encefálica. El estudio vascular no documentó una etiología diferente a la covid-19. DISCUSIÓN: Se plantea que la infección condiciona un estado inflamatorio sistémico, endotelialitis, ulceración de placas ateroscleróticas preexistentes e hipercoagulabilidad. Lo anterior facilita la aparición de trombosis vascular. Es frecuente encontrar elevación de reactantes de fase aguda y de los productos del metabolismo de la fibrina. El accidente cerebrovascular (ACV) isquémico se ha descrito en el 1 al 5 % de los pacientes con la covid-19. En pacientes con factores de riesgo cardiovascular, durante las primeras 2 semanas desde el inicio de los síntomas respiratorios, el compromiso isquémico suele afectar a múltiples territorios vasculares. CONCLUSIÓN: La covid-19 por sí sola es un factor de riesgo para trombosis arterial secundaria a la inflamación sistémica y estados de hipercoagulabilidad, por lo que debe ser tenida en cuenta en el estudio de ACV isquémico en pacientes jóvenes.


ABSTRACT INTRODUCTION: It is known that COVID-19 is associated with venous and arterial thromboembolic events in patients with history of hypertension and atherosclerosis. Herein, it is presented a case of a young woman without known cardiovascular risk, who was infected by SARS-COV 2 and then an ischemic stroke. CASE: 44 years-old woman with moderate COVID-19 in protocolary treatment with anticoagulants, steroid and oxygen. In the seventh day since symptoms onset, she presented acute ischemic stroke due to acute thrombosis of right carotid artery, and right and left medial cerebral arteries, then rapidly developed malignant cerebral edema and brain death. Vascular study failed to report and etiology other than COVID-19. DISCUSSION: It is suggested that the infection produces a systemic inflammatory state, endothelialitis, ulceration of preexisting atherosclerotic plaques, and hypercoagulability that facilitate thrombosis. Ischemic stroke is described in 1 to 5% of COVID-19, it is common to find an elevation of acute phase reactants and products of fibrin metabolism. Multiple vascular territories are usually compromised in patients with known cardiovascular risk factors and 12 days after the onset of symptoms. CONCLUSION: COVID-19 by itself is a risk factor for arterial thrombosis secondary to systemic infection and hypercoagulability states and it should be taken into account in the study of ischemic stroke in young patients.

RESUMO

Resumen Introducción: la estimación temprana del riesgo en falla cardiaca aguda puede ayudar en la toma de decisiones clínicas. Objetivo: identificar los factores de riesgo asociados a mortalidad intrahospitalaria en pacientes con falla cardiaca aguda. Métodos: análisis de una cohorte retrospectiva de pacientes mayores de 18 años ingresados a hospitalización por falla cardiaca aguda en un hospital de tercer nivel, entre los años 2012 y 2016. Resultados: se incluyeron 247 pacientes, con edad promedio de 62,8 años; predominó el sexo masculino con un 60%. El 84% de los pacientes tenía falla cardiaca con fracción de expulsión disminuida (mediana de 25%). La mortalidad intrahospitalaria fue de 9,3% y la acumulada a 30 días y 6 meses posterior al egreso hospitalario fue de 10,9 y 14,1%, respectivamente. Los dos predictores asociados a muerte intrahospitalaria fueron el nitrógeno ureico en sangre (BUN)> 37 mg/dl (OR: 10,8; 95% IC: 4,10-28,8) y la presión arterial sistólica (PAS) ≤ 125 mm Hg (OR: 3,42; 95% IC:1,15-10,0). El modelo de árbol de regresión y clasificación (CART) identificó como el mejor predictor de mortalidad los niveles elevados de BUN (≥ 32,5 mg/dl), seguido por la presión sistólica disminuida (< 97 mm Hg) y finalmente por los niveles elevados de creatinina (≥ 1,75 mg/dl). Conclusión: el análisis mediante el CART permite clasificar en forma temprana la probabilidad de muerte por un árbol de riesgo que incluye el BUN ≥ 32,5 mg/dl, la presión sistólica < 97 mm Hg y los niveles de creatinina ≥ 1,75 mg/dl.


Abstract Introduction: The early estimation of risk in acute heart failure may help in the taking of clinical decisions. Objective: To identify the risk factors associated with in-hospital mortality in patients with acute heart failure. Methods: An analysis was performed on a retrospective cohort of patients greater than 18 years admitted to a tertiary hospital due acute heart failure between the years 2010 and 2016. Results: A total of 247 patients were included, with a mean age of 62.8 years, and of which 60% were male. The large majority (84%) of the patients had heart failure with a reduced ejection fraction (median 25%). The in-hospital mortality was 9.3%, and the accumulated rate at 30 days and 6 months after hospital discharge was 10.9% and 14.1%, respectively. The two predictors associated with in-hospital death was a blood urea nitrogen (BUN) > 37 mg/dL (OR: 10.8; 95% CI: 4.10-28.8) and a systolic blood pressure (SBP) ≤ 125 mmHg (OR: 3.42; 95% CI: 1.15-10.0). The classification and regression tree (CART) model identified elevated levels of as the best predictor of mortality, followed by a decreased systolic pressure (< 97 mmHg), and finally due to elevated creatinine levels (≥ 1,75 mg/dL). Conclusion: The analysis using the classification and regression tree (CART) model can provide an early classification of the probability of death by a risk tree that includes BUN ≥ 32.5 mg/dL, systolic pressure <97 mm Hg, and creatinine levels ≥ 1.75 mg/dL.

RESUMO

Description: The purpose of this guidance statement is to guide clinicians on colorectal cancer screening in average-risk adults. Methods: This guidance statement is derived from a critical appraisal of guidelines on screening for colorectal cancer in average-risk adults and the evidence presented in these guidelines. National guidelines published in English between 1 June 2014 and 28 May 2018 in the National Guideline Clearinghouse or Guidelines International Network library were included. The authors also included 3 guidelines commonly used in clinical practice. Web sites were searched for guideline updates in December 2018. The AGREE II (Appraisal of Guidelines for Research and Evaluation II) instrument was used to evaluate the quality of guidelines. Target Audience and Patient Population: The target audience is all clinicians, and the target patient population is adults at average risk for colorectal cancer. Guidance Statement 1: Clinicians should screen for colorectal cancer in average-risk adults between the ages of 50 and 75 years. Guidance Statement 2: Clinicians should select the colorectal cancer screening test with the patient on the basis of a discussion of benefits, harms, costs, availability, frequency, and patient preferences. Suggested screening tests and intervals are fecal immunochemical testing or high-sensitivity guaiac-based fecal occult blood testing every 2 years, colonoscopy every 10 years, or flexible sigmoidoscopy every 10 years plus fecal immunochemical testing every 2 years. Guidance Statement 3: Clinicians should discontinue screening for colorectal cancer in average-risk adults older than 75 years or in adults with a life expectancy of 10 years or less.

RESUMO

One of the hallmarks of a trustworthy clinical guideline or guidance statement is a comprehensive process for disclosure of interests (DOI) and management of conflicts of interest (COIs). The American College of Physicians (ACP) Clinical Guidelines Committee (CGC) aims to disclose all health care-related interests and manage conflicts in a manner that is transparent, proportional, and consistent. Any person involved in the development of an ACP clinical guideline or guidance statement must disclose all financial and intellectual interests related to health care from the previous 3 years. Persons complete disclosures at the start of their participation and are required to update them over the course of their involvement with the CGC, including before each CGC meeting. A DOI-COI Review and Management Panel reviews the disclosures; flags potential conflicts; grades the COI as low-, moderate-, or high-level; and manages the person's participation accordingly. A high-level COI results in recusal from authorship, voting, and all committee discussions. Participants with a moderate-level COI are recused from authorship and voting for clinically relevant topics but may participate in all discussions. A low-level COI results in no role restrictions. All disclosures and COI management decisions are publicly reported.

RESUMO

The American College of Physicians (ACP) was one of the first organizations in the United States to develop evidence-based clinical guidelines and has been developing guidelines since 1981. ACP's Clinical Guidelines Committee (CGC), in collaboration with staff from the Clinical Policy department, develops clinical guidelines and guidance statements and continues to refine and enhance its methodology. This article presents an update of the CGC's 2010 paper outlining policies, methods, and presentation format of ACP's clinical guidelines and guidance statements. Updated methods include more stringent policies about disclosure of interests and conflict management; inclusion of public perspective; full adoption of GRADE (Grading of Recommendations Assessment, Development and Evaluation) methods; more standardized reporting formats that consider value of care, patient comorbid conditions, patient values and preferences, and costs; and further clarification of guidance statement methods.

RESUMO

Por encargo del Dr. Eugenio Matijasevik escribo este editorial para resaltar los grandes retos que tiene la Medicina Interna en este momento histórico de nuestro país y el mundo. Las noticias son buenas tenemos: un cubrimiento de nuestro sistema general de seguridad en salud de cerca del 98% de la población, tenemos una Ley Estatutaria en Salud que resalta la salud como un derecho fundamental para todos los colombianos, pero reafirma que la relación médico paciente es la fundamental resaltando la autonomía médica como factor principal en esta relación. Para nosotros los internistas, éstos son pasos en al dirección correcta, el eje de nuestra actividad médica es el paciente y la responsabilidad de las Facultades de Medicina y los Hospitales Universitarios formar internistas íntegros con gran capacidad técnica y profesional, pero todo ésto con base en el humanismo centrado en el bienestar del paciente y su familia. Pero el panorama no es claro, debido a la dirección que ha tomado nuestro sistema de salud que crea intermediarios en la atención en salud, donde no está claro que el eje es la salud del paciente, aleja al paciente de su médico y limita la autonomía médica y por lo tanto nuestra actividad como internistas; se convierte en un deber de todos repensarnos y definir el futuro de manera grupal, pero con base en el internista individual.

RESUMO

INTRODUCTION: More information is needed on the risk of venous thromboembolism in the hospital setting, and on patterns of use of thromboprophylaxis, as advocated in consensus guidelines. ENDORSE was an international study aimed at evaluating hospital venous thromboembolism prevention practices in medical and surgical patients. OBJECTIVES: The risk of venous thromboembolism was evaluated along with the use of thromboprophylaxis in hospitalized medical and surgical subjects; these data were compared with the international sample from the ENDORSE study. MATERIALS AND METHODS: Participating institutions in Colombia were selected arbitrarily. The medical charts for medical and surgical patients were evaluated randomly. The 2004 American College of Chest Physician guidelines were used to evaluate risk of venous thromboembolism and adherence to recommended thromboprophylaxis regimens. RESULTS: The study included 761 subjects (218 surgical, 543 medical) located in five acute care hospitals; 49% of these subjects were considered at risk of venous thromboembolism (40% medical, 72% surgical), compared with 52% in the international sample. Prophylaxis use was higher in medical patients at risk (63.7%, n=137) than in surgical patients (48.4%, n=76; p=0.01). Compared with the international sample, the use of prophylaxis in Colombia was greater in medical patients (63.7% vs. 39.5%, p=0.003), but lower in surgical patients (48.4% vs. 58.5%, p=0.02). CONCLUSIONS: Participating Colombian centers treat patients at risk of venous thromboembolism similarly to other participant countries, but appropriate prophylaxis was prescribed more frequently to medical patients. Greater efforts are needed, both in Colombia and around the world, to improve rates of appropriate venous thromboembolism prophylaxis in at-risk subjects.

RESUMO

Introducción. La profilaxis en pacientes de tratamiento médico o quirúrgico con riesgo de tromboembolia venosa, requiere ser evaluada para obtener suficiente información que contribuya a mejorar estas prácticas, para que sean efectivas y eficaces, y ayudar con las medidas necesarias de prevención hospitalaria de la tromboembolia venosa. Objetivo. Evaluar el riesgo de tromboembolia venosa y de los hábitos de profilaxis en pacientes de tratamiento médico o quirúrgico hospitalizados en Colombia y compararlos con los de los centros internacionales participantes en el estudio ENDORSE. Materiales y métodos. Las instituciones fueron escogidas al azar. Se evaluaron todas las historias clínicas de pacientes de tratamiento médico o quirúrgico. Se utilizaron las guías del 2004 del American College of Chest Physicians para evaluar el riesgo de tromboembolia venosa y lo apropiado de la profilaxis. Resultados. Se evaluaron 761 pacientes: 218 de tratamiento quirúrgico y 543 de tratamiento médico, de cinco centros hospitalarios de Colombia. De esta población, 49 % se encontraba en riesgo de tromboembolia venosa (40 % de los de tratamiento médico y 72% de los de tratamiento quirúrgico), en comparación con 52 % de la muestra internacional. La profilaxis fue significativamente mayor en los pacientes de tratamiento médico en riesgo (63,7 %, n=137), que en los de tratamiento quirúrgico (48,4 %, n=76, P=0,01). En comparación con la muestra internacional, la profilaxis en los de tratamiento médico fue significativamente superior (63,7 % Vs. 39,5 %, P=0,003), a diferencia de los de tratamiento quirúrgico (48,4 % Vs. 58,5 %, P=0,02). Conclusiones. Los resultados muestran que en los centros hospitalarios de Colombia se trataron pacientes con riesgo de tromboembolia venosa en forma similar al resto de los países participantes en el estudio ENDORSE, y que se hizo más profilaxis apropiada en pacientes de tratamiento médico. Sin embargo, se requiere mejorar la utilización de profilaxis en pacientes hospitalizados.

RESUMO

Introducción: la embolia pulmonar (EP) se asocia con morbilidad y mortalidad sustanciales, sin embargo existe muy poca información proveniente de países latinoamericanos. Los objetivos de este estudio fueron el describir el curso clínico y la supervivencia de una cohorte con EP, e identificar factores asociados con la mortalidad hospitalaria.Pacientes y método: estudio de cohorte en instituciones de cuatro ciudades colombianas. Pacientes adultos con EP por criterios previamente establecidos, fueron invitados a participar. La información sobre factores de riesgo, cuadro clínico, exámenes, tratamientos, y estado vital al alta hospitalaria y hasta por 12 meses, fue recogida sistemáticamente por personal entrenado.Resultados: el total de pacientes incluidos fue 251, con edad promedio de 65 años (DE 18); 66 porciento fueron mujeres. La frecuencia de trombo-profilaxis fue 22 porciento. La mortalidad hospitalaria fue 14.8 porciento (IC95 porciento: 11 – 19 porciento). Factores asociados con mortalidad hospitalaria incluyeron hipotensión (RR: 2.57; IC95 porciento: 1.4 – 4.73) y fractura de cadera (RR: 2.55; IC95 porciento: 1.34-4.83). La supervivencia a las 52 semanas poshospitalización fue 85 porciento (IC95 porciento: 79-90 porciento).Conclusiones: en esta cohorte colombiana, la EP estuvo asociada con mortalidad sustancial temprana y tardía. La mayor mortalidad en pacientes con fractura de cadera refuerza la necesidad de uso rutinario de estrategias de tromboprofilaxis efectivas y seguras.

RESUMO

Los tumores carcinoides son tumores neuroendocrinos raros derivados de células enterocromafines. Han sido reportados en órganos como pulmón, bronquios y en el espacio tractogastrointestinal. La clasificación patológica de la Organización Mundial de la Salud (OMS) de 1999 los divide en tumores carcinoides típicos, tumores carcinoides atípicos y carcinoma de célula pequeña. Los hallazgos radiológicos incluyen masa hiliar o perihiliar, nódulos endobronquiales, hallazgos secundarios a obstrucción bronquial y nódulo solitario. Se presentan, así mismo, los hallazgos patológicos, clínicos, radiológicos y quirúrgicos del tumor carcinoide, y se revisan las características descritas en la literatura.
