RESUMO

One of the main skills in internal medicine is clinical decision making. To make clinical decisions, physicians in training reorganize their knowledge in order to optimally perform their clinical functions (diagnosis, research methods and treatment), which are organized according to disease scripts. This ability develops with experience and is acquired during their academic training. The script concordance test has been described as an innovative evaluation tool, designed to evaluate clinical decision making (clinical reasoning) in addition to the degree of knowledge. The script theory, understood as the organization of knowledge, is the basis for decision making. Disease scripts play a key role in supporting and developing clinical reasoning skills, which should be acquired in order to produce differential diagnoses and interpret clinical data.

RESUMO

The objective of this study was to evaluate the effects of different sealing strategies on aerobic stability and feed value of corn silage supplied to finishing lambs. The treatments were set up according to the silo sealing strategy: BP (black polyethylene film), BP + Bagasse (black polyethylene film + sugarcane bagasse) and BP + Silostop (Silostop® Orange oxygen barrier film + black polyethylene film). Six lambs per treatment were used, totaling 18 animals in an experimental period of 63 days. The silage from LP treatment presented the highest aerobic stability, however with lower dry matter digestibility coefficients. No significant differences were detected among treatments for intake and performance of lambs. But for final body weight, weight gain, daily average gain, feed efficiency and dry matter intake, the best results, in absolute value, were found for lambs fed with silage from LP + Bagasse treatment. The silage sealed exclusively with black polyethylene film showed greater aerobic stability. The different sealing strategies used in this experiment did not influence the performance of finishing Dorper x Santa Inês lambs.(AU)


Objetivou-se avaliar os efeitos de differentes estratégias de vedação sobre a estabilidade aeróbia e o valor alimentício da silagem de milho fornecida para cordeiros em terminação. Os tratamentos foram definidos de acordo com a estratégia de vedação do silo: LP (lona preta de polietileno), LP + Bagaço (lona preta de polietileno + bagaço de cana) e LP + Silostop (lona preta de polietileno + filme de barreira de oxigênio Silostop® Orange). Foram utilizados seis cordeiros por tratamento, totalizando 18 animais, em um período experimental de 63 dias. A silagem do tratamento LP apresentou maior estabilidade aeróbia, porém proporcionou menor coeficiente de digestibilidade da matéria seca. Não foi observada diferença significativa entre os tratamentos para o consumo e desempenho dos cordeiros. Todavia, para o peso corporal final, ganho de peso, ganho médio diário, eficiência alimentar e consumo de matéria seca, os melhores resultados, em valor absoluto, foram encontrados para os cordeiros alimentados com dieta à base da silagem coberta com LP + Bagaço. A silagem vedada exclusivamente com a lona preta de polietileno apresentou maior estabilidade aeróbia. As diferentes estratégias de vedação utilizadas nesse experimento não influenciaram o desempenho de cordeiros Dorper x Santa Inês em terminação.(AU)

RESUMO

Resumen Los grandes avances terapéuticos de las últimas décadas han prolongado la sobrevida de muchos pacientes con cáncer. Sin embargo, esta mejoría se ha logrado a expensas de un aumento en las complicaciones cardiovasculares secundarias a la quimioterapia y a la radioterapia. Se presenta el caso de un paciente con cáncer esofágico que manifiesta angina inestable como complicación de su enfermedad coronaria multivaso tras iniciar la quimioterapia (capecitabina/oxaliplatino/epirubicina), se discuten los posibles mecanismos que subyacen al evento y se subraya la necesidad de individualizar la estratificación de riesgo previa a la quimioterapia.


Abstract The great therapeutic advances of the last decades have prolonged the survival of many cancer patients. However, these advances have been made at the expense of an increase in cardiovascular complications secondary to chemotherapy and/or radiotherapy. It is presented a patient with oesophageal cancer who manifests unstable angina as a complication of multivessel coronary artery disease after starting chemotherapy with capecitabine/oxaliplatin/epirubicin, discussing the possible mechanisms underlying the event and emphasizing the need to personalize the risk stratification before chemotherapy.

RESUMO

The objective was to evaluate the inclusion of chitosan (CHI) and technical cashew nut shell liquid (CNSLt) as natural feed additives in cattle diets on nutrient digestibility, ruminal fermentation, and in vitro gas production kinetics. We conducted a completely randomized design with 5×4 factorial arrangement, with 20, 35, 50, 65, and 100% Tifton 85 hay and four additives, monensin (200 mg/kg DM), CNSLt (500 mg/kg DM), CHI (500 mg/kg DM), and CNSLt+CHI (500 mg/kg DM/each). Dry matter (DM) and organic matter (OM) digestibility showed a linear reduction according to forage levels. The highest DM digestibility was observed with CHI on cattle diets. Inclusion of CHI increased DM digestibility. The highest in vitro organic matter and crude protein (CP) digestibilities were observed for CNSLt+CHI. The in vitro dry matter digestibility increased linearly with concentrate in the diet. There was interaction of forage:concentrate ratio and the additives for neutral detergent fiber, acid detergent fiber and hemicellulose digestibility. Chitosan, CNSLt, and CNSLt+CHI promoted the lowest acetate:propionate ratio compared with monensin. Total gas production showed interaction of the forage:concentrate ratio and additives. Lag time was lowest with CNSLt+CHI. Chitosan and CNSLt can be considered alternative fermentation modulators to ionophores by improving nutrient digestibility and increasing ruminal propionate concentrations.(AU)

RESUMO

RESUMEN: El hepatoblastoma (HB), es una neoplasia maligna, que se origina en el hígado. La supervivencia (SV) depende de la extensión de avance de la enfermedad. El objetivo de este estudio fue determinar diferencias en la SV actuarial global (SVAG) y libre de enfermedad (SVLE) en pacientes con HB, según la extensión de su enfermedad. Serie de casos con seguimiento. Se incluyeron pacientes de entre 4 y 160 meses de edad tratados en un centro oncológico de Los Andes ecuatorianos (2000-2019). Las variables resultado fueron: lóbulo afectado, metástasis pulmonar, infiltración vascular, estadio PRETEXT, riesgo, histología, niveles de alfafetoproteína (AFP), remisión completa (RC), SVAG y SVLE. Se utilizó estadística descriptiva y analítica (Chi2, exacto de Fisher y corrección por continuidad). Se realizaron análisis de SV con curvas de Kaplan Meier y log-rank. Fueron estudiados 28 pacientes (53,6 % hombres), con una mediana de edad de 40 meses. Se verificaron metástasis pulmonares e infiltración vascular en el 25,0 % y 35,7 % de los casos respectivamente. La histología, estadio clínico y riesgo alto fueron mayoritariamente tipo epitelial (42,8 %), PRETEXT II (50,0 %) y riesgo alto (67,8 %) respectivamente. La media de AFP al diagnóstico fue 1055712ng/ml y 9 pacientes alcanzaron RC. La SVAG y SVLE general a 19 años fue 33,1 % y 26,0 % respectivamente. Según su extensión, la SVAG y la SVLE para los pacientes de riesgo estándar y alto fueron 50,0 % y 25,4 % (p=0,148); y 50,0 % y 14,7 % (p=0,037) respectivamente. La SVAG y SVLE verificadas son menores a las reportadas en otros estudios. La SVLE según su extensión, presentó diferencia significativa, sin embargo, este resultado debe ser tomado con cautela debido al número pequeño de pacientes.


SUMMARY: Hepatoblastoma (HB), is a malignant neoplasm, which originates in the liver. Survival (SV) depends on the extent of disease progression. The objective of this study was to determine differences in overall SV (OS) and disease-free (DFS) in patients with HB, according to the extent of their disease. Case series with follow-up. Patients between 4 and 160 months of age treated at an oncology center in the Ecuadorian Andes (2000-2019) were included. The result variables were affected lobe, lung metastasis, vascular infiltration, PRETEXT stage, risk, histology, alpha-fetoprotein levels (AFP), complete remission (RC), OS and DFS. Descriptive and analytical statistics (Chi2, Fisher's exact and continuity correction) were used. SV analyzes were performed with Kaplan Meier and log-rank curves. In this analysis 28 patients (53.6 % men), with a median age of 40 months, were studied. Lung metastases and vascular infiltration were verified in 25.0 % and 35.7 % of the cases, respectively. Histology, clinical stage, and high risk were mainly epithelial type (42.8 %), PRETEXT II (50.0 %), and high risk (67.8 %), respectively. The mean AFP at diagnosis was 1055712 ng / ml and 9 patients achieved CR. OS and DFS at 19 years were 33.1 % and 26.0 % respectively. According to their extension, the OS and DFS for standard and high risk patients were 50.0 % and 25.4 % (p = 0.148); and 50.0 % and 14.7 % (p = 0.037) respectively. The verified OS and DFS are lower than those reported in other studies. DFS according to its extension, presented a significant difference, however, this result should be considered with caution due to the small number of patients.

RESUMO

Introducción: La manometría anorrectal de alta resolución ha permitido una mayor comprensión de la fisiopatología del daño motor y sensorial, que suelen tener los pacientes con disfunción del suelo pélvico. Objetivo: Ofrecer los resultados de la introducción de la técnica en Cuba, en un primer grupo de pacientes, la caracterización del mismo, los valores obtenidos para los parámetros de estudio y los diagnósticos más frecuentes. Material y Métodos: Se revisaron los registros de manometría anorrectal de alta resolución, realizados en el Laboratorio de Motilidad del CNCMA, entre septiembre de 2017 y junio de 2019. Se analiza el registro de los datos generales de los pacientes y los parámetros específicos de alta resolución. Se estudiaron 159 pacientes que constituyeron el universo de estudio, la mayoría fueron pacientes por encima de los 60 años. Se aplica la Clasificación de Londres para el diagnóstico del tipo de disfunción anorrectal resultante. Resultados: Predominio de sexo femenino. La indicación más frecuente para la prueba fue la incontinencia fecal, seguida en menor medida por el estreñimiento. En las mujeres fue frecuente el antecedente obstétrico o de intervención quirúrgica relacionada. La disinergia defecatoria más frecuente fue el tipo III. El diagnóstico de disfunción anorrectal más frecuente fueron los desórdenes del tono anal y la contractilidad. Conclusiones: La introducción de la técnica fue exitosa. Se introdujeron en Cuba los estudios de manometría anorrectal de alta resolución, lo que permitió mayor conocimiento del daño establecido en los pacientes a quienes se les realiza la prueba, siendo la IF la disfunción que resultó más frecuente en el estudio. Se obtuvieron por primera vez parámetros específicos de alta resolución en pacientes cubanos, lo que permitirá estandarizar la técnica a otros servicios y tendrá como consecuencia mayor calidad en el diagnóstico de estos pacientes(AU)


Introduction: High-resolution anorectal manometry has allowed a better understanding of the pathophysiology of motor and sensory damage in patients with pelvic floor dysfunction. Objective: To offer the outcomes of the introduction of the technique applied in a first group of patients in Cuba, as well as its characterization, the values obtained for the study parameters and the most frequent diagnoses. Material and Methods: The high-resolution anorectal manometry records, which were performed at the CNCMA Motility Laboratory between September 2017 and June 2019, were reviewed. The record of the patients´ general data and specific discharge parameters were analyzed. The London Classification was applied for the diagnosis of the resulting type of anorectal dysfunction. Results: A total of 159 patients were studied. There was a predominance of females over 60 years of age. The most common indication for the test was fecal incontinence, followed by constipation. Obstetric history or history of surgical intervention were frequent in women. Type III dyssynergia was the most frequent type of dyssynergic defection. The most frequent diagnoses of anorectal dysfunction were disorders of anal tone and contractility. Conclusions: The introduction of the technique was successful. It allowed the identification of the damaged structures, which led to a faster and more timely therapeutic decision-making for the patient. The London Classification was used in the diagnosis of dysfunction(AU)

RESUMO

Introducción: La manometría esofágica de alta resolución es la prueba ideal para el diagnóstico de la acalasia y muestra la presencia de ondas terciarias o aperistalsis y el aumento de presión, con ausencia de relajación, del esfínter esofágico inferior. Objetivo: Evaluar la utilidad de la manometría esofágica de alta resolución en el diagnóstico y clasificación de la acalasia esofágica. Métodos: Se realizó una investigación descriptiva, trasversal, en el Centro Nacional de Cirugía de Mínimo Acceso entre octubre del 2018 y diciembre del 2019, en 46 pacientes con diagnóstico de acalasia esofágica. Se excluyeron aquellos con cirugía previa del esófago. Las variables incluidas fueron: edad, sexo, tiempo de evolución, síntomas y hallazgos manométricos. Para el análisis de las variables cuantitativas se emplearon medidas de tendencia central, media y de dispersión, la desviación estándar. Las frecuencias y proporciones fueron utilizadas para describir las variables cualitativas. Resultados: Predominó la acalasia tipo II, en el sexo femenino (57 por ciento). La disfagia fue el síntoma más frecuente (84, 76 y 100 por ciento en los tipos I, II y III, respectivamente). El 70 por ciento de los casos presentó más de un año de evolución de los síntomas. La media de la presión de relajación integrada estuvo por encima de 21 mmHg independientemente del tipo. No se encontraron pacientes con subtipos de la acalasia tipo III. Conclusiones: La manometría esofágica de alta resolución es útil para el diagnóstico y clasificación de la acalasia esofágica(AU)


Introduction: High-resolution esophageal manometry is the ideal test for the diagnosis of achalasia and shows the presence of tertiary waves or aperistalsis and increased pressure, in the absence of relaxation, of the lower esophageal sphincter. Objective: To assess the usefulness of high-resolution esophageal manometry in the diagnosis and classification of esophageal achalasia. Methods: A descriptive, cross-sectional investigation was carried out at the National Center for Minimal Access Surgery, between October 2018 and December 2019, in 46 patients with a diagnosis of esophageal achalasia. Those with previous esophageal surgery were excluded. The variables included were: age, sex, time of evolution, symptoms and manometric findings. For the analysis of the results, the percentage and measures of central tendency (arithmetic mean and standard deviation) were used. Results: Type II achalasia predominated in females (57 percent). Dysphagia was the most frequent symptom (84, 76, and 100 percent in types I, II, and III, respectively). 70 percent of the cases presented more than one year of evolution of the symptoms. Regarding the high-resolution manometry parameters, it was observed that regardless of the type, the mean integrated relaxation pressure was above 21 mmHg. No patients with type III achalasia subtypes were found. Conclusions: High-resolution esophageal manometry is useful for the diagnosis and classification of esophageal acalasia(AU)

RESUMO

Introducción: El aneurisma de la aorta abdominal es una enfermedad que cursa, por lo general, de forma asintomática, asociado a una elevada mortalidad cuando se rompe. Se describen factores de riesgo asociados a la historia natural de esta afección. La realización de procederes terapéuticos endoscópicos, como la colangiopancreatografía retrógrada endoscópica ha sido polémica; aunque no se establece como contraindicación, presupone un alto riesgo. Objetivo: Presentar un paciente con aneurisma de la aorta abdominal, con elevado riesgo quirúrgico para realizar una colangiopancreatografía retrógrada endoscópica. Caso clínico: Se presenta un paciente con un gran aneurisma de la aorta abdominal y sospecha clínica de un ampuloma. Se le realizó terapéutica endoscópica mediante la colangiopancreatografía retrógrada endoscópica, con algunas variaciones en el procedimiento. Se logró el drenaje exitoso de la vía biliar principal, sin complicaciones. Conclusiones: La terapéutica realizada fue una opción, pero con muy alto riesgo(AU)


Introduction: The abdominal aortic aneurysm is a disease that usually occurs asymptomatically, associated with high mortality when it ruptures. Risk factors associated with the natural history of this condition are described. The performance of endoscopic therapeutic procedures, such as endoscopic retrograde cholangiopancreatography, has been controversial; although it is not established as a contraindication, it presupposes a high risk. Objective: To present a patient with an abdominal aortic aneurysm, with high surgical risk to perform an endoscopic retrograde cholangiopancreatography. Clinical case: A patient with a large abdominal aortic aneurysm and clinical suspicion of an ampuloma is presented. Endoscopic therapy was performed using endoscopic retrograde cholangiopancreatography, with some variations in the procedure. Successful drainage of the main bile duct was achieved without complications. Conclusions: The therapy carried out was an option, but with a very high risk(AU)

RESUMO

Resumen La linfocitopenia T CD4 idiopática (LCI) es un síndrome clínico inusual que se caracteriza por un déficit de células T CD4+ circulantes en ausencia de infección por VIH u otra condición de inmunosupresión. Los pacientes con dicha enfermedad pueden presentarse asintomáticos o con infecciones oportunistas, las más frecuentes son por criptococo, micobacterias o virales como herpes zoster. Presentamos el caso de un hombre de 32 años, sin antecedentes, en quien se descartó infección por retrovirus, con recuento de linfocitos T CD4+ menor a 300 células/m3; se diagnosticó LCI posterior al diagnóstico de criptococomas cerebrales mediante hallazgos imagenológicos los cuales fueron congruentes con estudios microbiológicos.


Summary Idiopathic CD4 T lymphocytopenia (ICL) is an unusual clinical syndrome characterized by a deficit of circulating CD4 + T cells in the absence of HIV infection or another immunosuppression condition. Patients with this disease may present asymptomatic or with opportunistic infections, the most frequent are cryptococcus, mycobacteria or viral such as herpes zoster. We present a case of a 32-year-old man with no prior disease, in whom retrovirus infection was discarded, with CD4 + T lymphocyte count less than 300 cells/m3; ICL was diagnosed after the diagnosis of brain cryptococomas by imaging findings which were consistent with microbiological studies.

RESUMO

RESUMEN: Introducción: La manometría esofágica de alta resolución se considera a nivel internacional como un método óptimo para el diagnóstico de los trastornos motores del esófago, de alta especificidad y sensibilidad. Dada la reciente introducción de la técnica en Cuba, se necesita demostrar su utilidad en nuestro país, donde no existe grado de conocimiento previo sobre cuáles son los parámetros de normalidad, así como los diagnósticos de alta resolución más frecuentes. Objetivo: Determinar la utilidad de la manometría esofágica de alta resolución como estudio diagnóstico para los trastornos motores del esófago en Cuba. Métodos: Se diseñó una investigación aplicada, de desarrollo, realizada en el Centro Nacional de Cirugía de Mínimo Acceso, en La Habana, entre junio de 2017 y junio de 2019, en pacientes a los que se les realizó una manometría esofágica. El universo de pacientes fue 611, a quienes se les registraron las variables en estudio. Resultados: De las 611 manometrías esofágicas, 356 correspondían a mujeres (58,3 por ciento) y 255 a hombres (42,7 por ciento), con un promedio de edad de 47, 44 años respectivamente. La motilidad inefectiva fue el trastorno motor más frecuente (32,73 por ciento). En los pacientes con Enfermedad por Reflujo Gastroesofágico, el principal daño de la barrera antirreflujo fue la presencia de relajaciones transitorias del esfínter esofágico inferior. Predominó la Acalasia tipo II (5,23 por ciento). En estos pacientes se registraron valores de Presión de relajación integrada (IRP) por encima de 21. Conclusiones: Se establecieron valores aplicables a pacientes cubanos, que permiten establecer el diagnóstico por alta resolución(AU)


ABSTRACT Introduction: High-resolution esophageal manometry is considered internationally as an optimal method for diagnosis of esophageal motor disorders. Given the recent introduction of the technique in Cuba, it is necessary to demonstrate its usefulness in our country where there is no prior knowledge about the most frequent parameters of normality and high resolution diagnoses. Objective: To determine the usefulness of high-resolution esophageal manometry as a method for the diagnosis of esophageal motor disorders in Cuba. Material and methods: An applied developmental research was designed and carried out at the National Center for Minimal Access Surgery in Havana between June 2017 and June 2019. The study included patients in whom esophageal manometry was performed. The universe consisted of 611 patients and the variables used in the study were recorded. Results: Of the 611 patients who underwent esophageal manometry, 356 were women (58.26 percent) and 255 were men (42.73 percent), with an average age of 47 and 44 years, respectively. Ineffective motility was the most frequent motor disorder (32,73 percent). In patients with Gastroesophageal Reflux Disease, the main damage of the antireflux barrier was the presence of transient lower esophageal sphincter relaxations. Type II achalasia predominated (5,23 percent). In these patients, integrated relaxation pressure (IRP) values above 21 were recorded. Conclusions: Values applicable to Cuban patients that allow to establish a high-resolution diagnosis were established(AU)
