ABSTRACT

El síndrome del ducto pancreático desconectado (SDPD) consiste en la disrupción del ducto pancreático principal con pérdida de continuidad entre el remanente pancreático distal viable y el tracto gastrointestinal, generalmente causado por necrosis ductal secundaria a pancreatitis aguda grave. Esto resulta en fuga de fluido pancreático, provocando un curso de enfermedad prolongado y complicaciones. La literatura sobre este tema es limitada, con algoritmos de tratamiento poco claros. Hemos realizado una revisión de la literatura sobre el tema. Revisión en Pubmed y Scielo (2011-2021) de artículos en inglés y español utilizando términos «síndrome del conducto pancreático desconectado», «DPDS» y «páncreas desconectado» encontrando 16 artículos relevantes. Dadas las pocas citas, se revisaron las referencias de estos artículos. Finalmente, revisamos un total de 21 artículos. Entre las referencias encontradas existe 1 metaanálisis, 4 estudios prospectivos y no existen ensayos aleatorizados.


Disconnected pancreatic duct syndrome (DPDS) is characterized by disruption of the main pancreatic duct with a loss of continuity between the viable upstream pancreatic parenchyma and the gastrointestinal tract, generally caused by ductal necrosis after severe acute necrotizing pancreatitis. This compromised ductal integrity leads to extraductal leakage of pancreatic secretions, causing a prolonged disease course and complications. The existing literature is limited, with unclear therapeutic algorithms. We have performed a review of the literature on DPDS. Review in Pubmed and Scielo (2011-2021) of articles in English and Spanish using the terms "disconnected pancreatic duct syndrome", "DPDS" and "disconnected pancreas" finding 16 relevant articles. Given the few citations, the references of these articles was reviewed. Finally, we found 21 articles. Among them, there is one meta-analysis, 4 prospective studies and no randomized trials.

ABSTRACT

Resumen Introducción: Diversas patologías requieren de tratamiento anticoagulante oral (TACO). Algunos de estos pacientes requieren resolución quirúrgica. El manejo perioperatorio de estos pacientes es variable dependiendo del centro. Objetivos: Evaluar la morbilidad y mortalidad del protocolo de manejo de patología herniaria en TACO, atendidos en nuestro hospital. Material y Métodos: Estudio descriptivo prospectivo de 37 pacientes sometidos a cirugía herniaria en TACO entre 2008-2016. Los datos fueron obtenidos de la base de datos computacional del Equipo de Hernias, con un seguimiento mínimo de 1 mes. Se evaluaron las características clínicas, quirúrgicas y la morbimortalidad postoperatoria. El traslape consistió en hospitalizar al paciente tres días previos a la cirugía, suspendiéndose el TACO e iniciando heparina de bajo peso molecular (HBPM) en dosis terapéuticas, que se suspende 24 h previas a la cirugía. Se reinicia la HPBM a las 12 a 24 h postoperatorias, y se inicia el traslape a TACO a las 24-48 h. Los datos fueron analizados con Stata v14. Resultados: De los 37 pacientes estudiados, veintiséis pacientes fueron hombres (70,2%), la media de edad fue de 67,3 años. El 48,7% tenían fibrilación auricular. El 100% consumía acenocumarol como TACO. La media en el inicio del traslape a la anticoagulación oral fue de 1,4 días. El promedio de INR al momento del alta fue de 2,04. Dos pacientes fueron dados de alta con dalteparina. Un paciente (2,7%), presentó dolor en el postoperatorio inmediato y uno (2,7%), equimosis del sitio quirúrgico. Conclusiones: El protocolo de trabajo utilizado, demostró ser seguro, con una mínima morbilidad postoperatoria.


Introduction: Various pathologies require oral anticoagulant treatment (TACO). Some of these patients present pathologies of surgical resolution. The perioperative management of these patients is variable depending on the center. Aim: To evaluate the morbidity and mortality of patients attended with hernia pathology and TACO, assisted in our hospital. Materials and Method: Prospective, descriptive study of 37 patients submmited to hernia surgery in TACO between 2008-2016. The data was obtained from the computer database of the Hernia Team, with a minimum follow-up of 1 month. Clinical, surgical characteristics and postoperative morbidity and mortality were evaluated. The treatment overlap from TACO to Low Molecular Weight Heparin (LMWH) in therapeutic doses, was initiated three days before surgery. LMWH was suspended 24 hours prior to surgery, and reinitiated 12 to 24 hours post operation. 48 to 72 hours TACO was resumed. The data was analyzed with Stata v14. Results: Twenty-six patients were men, the mean age was 67.3 years. 48.7% had atrial fibrillation. 100% consumed acenocoumarol as TACO. The mean time for resuming TACO after surgery was 1.4 days. The average INR at the time of discharge was 2.04. Two patients were discharged with dalteparin. One patient (2.7%) presented pain in the immediate postoperative period and one showed ecchymosis of the surgical site (2.7%). Conclusions: The work protocol used, proved to be safe, with minimal postoperative morbidity.

ABSTRACT

Resumen Introducción: La resección abdominoperineal (RAP) era el tratamiento estándar del cáncer de recto medio o bajo quedando el paciente sin ano y con una ostomía permanente. En los últimos 20 años el desarrollo de nuevas técnicas quirúrgicas, con adecuados resultados quirúrgicos y oncológicos, han permitido ofrecer al paciente la preservación del aparato esfinteriano, sin embargo, éstas pueden presentar problemas de tipo funcional lo que podría derivar en una alteración de la calidad de vida del paciente. Objetivo: Comparar la alteración en la calidad de vida en pacientes sometidos a RAP versus técnicas con preservación de esfínter anal en pacientes operados por cáncer de recto. Materiales y Método: Estudio de cohorte transversal con pacientes operados por cáncer de recto medio-bajo en nuestro hospital entre los años 2009 a 2015. Se utiliza el instrumento EuroQuol-5D2,3 validado en español chileno. Resultados: Se incluyen 39 pacientes, 11 corresponden a colostomía definitiva y 28 a preservación de esfínter. En el análisis por dominios se observaron diferencias significativas en el grupo con ostomía definitiva en el ítem de actividades habituales y a favor de la preservación de esfínter en el ítem sexualidad. Conclusiones: La técnica quirúrgica utilizada en pacientes con cáncer rectal medio-bajo altera la calidad de vida, razón por la cual debe ser adecuadamente seleccionada y además advertir al paciente de las consecuencias que dicha cirugía puede ocasionar.


Introduction: The abdominoperineal resection (APR) was the standard treatment of middle-low rectal cancer, in the last 20 years the development of sparing techniques with sphincter preservation with adequate surgical and oncological results has allowed to offer the patient the sphincter apparatus preservation, avoiding the definitive colostomy, however, these techniques may present secondary incontinence to the loss of the rectum. Both surgical options can affect the quality of life of the patient and this element should be considered. Objective: To compare the change in quality of life of patients undergoing APR vs sphincter preserving techniques in patients operated for rectal cancer. Materials and Method: Cross-sectional cohort study with medium-low rectal cancer patients, operated in our hospital from 2009 to 2015. The instrument EuroQuol-5D2, validated in chilean spanish is used. Results: 39 patients were included (11 definitive colostomy and 28 sphincter preservation). In the analysis by domains, significant differences were observed favor to definitive colostomy in the Item of "Habitual Activities" and favor to sphincter preservation in the Item "Sexuality". Conclusions: In patients with middle-low rectal cancer, the choice of surgical technique have a measurable impact on the patient's quality of life.

ABSTRACT

Durante los últimos años se ha estudiado la relación entre enfermedad de Graves (EG), TSH, TRAb y cáncer de tiroides, existiendo estudios que demuestran mayor prevalencia y agresividad del cáncer de tiroides en pacientes con EG, mientras otros refutan estos hallazgos sugiriendo que serían producto del sesgo de selección. Aquellos estudios que plantean una relación causal entre EG y el desarrollo de cáncer de tiroides, la atribuyen a la presencia de autoanticuerpos TSI, que estimularían el foco de malignidad. Se cree que las citoquinas producidas localmente en pacientes con EG trabajarían en conjunto con los TRAb para determinar la agresividad del cáncer papilar de tiroides en estos pacientes. Dentro de las células reclutadas por el tumor para evadir la respuesta inmune se encuentran los linfocitos Treg, que estarían elevados en paciente con EG, llevando a la disminución de la respuesta inmune y creando un ambiente permisivo para la proliferación celular. Por tratarse de una línea de investigación reciente, no existe consenso sobre el tema y sus implicancias en el tratamiento de los pacientes con EG. La finalidad de este artículo es realizar una revisión de la literatura que exponga y contraste la información disponible a la fecha.


In recent years the relationship between Graves’ disease (GD), TSH, TRAb and thyroid carcinoma has been studied. Research studies show a higher prevalence and aggressiveness of thyroid carcinoma in patients with GD, however other researchers refute these findings suggesting it’s due to selection bias. Increasing evidence suggests a causal relationship between GD and the development of thyroid carcinoma, mainly because of the existence of TSI autoantibodies that could stimulate the focus of malignancy. It is believed that cytokines produced locally in patients with GD work alongside with TRAb regulating the aggressiveness of papillary thyroid carcinoma in these patients. Within the cells recruited by the tumor to elude the immune system we find Treg lymphocytes, which have been found to be increased in patients with GD, leading to a diminished immune response, creating a permissive environment for cell proliferation. Since this is a relatively new line of research, there is no consensus on the subject and its relevance for the treatment of patients with GD. The aim of this article is to show recent literature available on the subject.

ABSTRACT

The prevalence of diabetes has increased considerably, constituting a global epidemic today. Many of these patients will develop chronic complications of diabetes, including diabetic foot, which aggravates the patient’s clinical condition, decreases the quality of life and has a great socioeconomic impact. The most important action to reduce the morbidity and mortality associated with this pathology is the prevention of this complication, performing a propermetabolic management and serial control of the patient, educating about self-care of the feet. Once diabetic foot ulcer is present, the cornerstones of treatment are debridement of the wound, management of any infection, revascularization procedures when indicated, and discharge of the ulcer, all of the above in order to avoid amputation. This article intends tomake a review about the epidemiology, pathophysiology, classification, diagnosis, prevention and management of diabetic foot oriented to the primary care doctor.

ABSTRACT

Central Venous Port Catheters are increasingly used in critically ill patients for intravenous treatments and nutrition, and lately, a main focus of oncology patients receiving chemotherapy. Besides all advantages they have also added a new set of challenges. In this case report we describe the acute presentation of a right hemidiaphragm paralysis in an oncology patient with recurrent breast ductal carcinoma as an immediate rare complication of a right subclavian vein catheterization and port insertion.

ABSTRACT

Background: In Chile, 10 percent of deaths in adults are directly attributed to smoking. Aim: To identify intrinsic and extrinsic motivations to quit smoking among a group of subjects that quitted without external help. Material and methods: The motivations to quit smoking were measured using the 20 items Reasons for Quitting Scale (RFQ), in 145 ex smokers (80 students and 65 workers at The University of Concepcion). The scale identifies intrinsic motivations in the categories health and self control and extrinsic motivations in the categories immediate reinforcement and social pressure. Results: Factorial analysis with orthogonal rotation of the 20 items of the scale, suggested an optimal solution with five factors, that had a maximal impact of 0.43 and explained the motivations in up to a 66 percent of workers and 65 percent of students. The factors with the greater impact were the items of immediate reinforcement, social pressure and self control. The category health had only a 6 percent influence in the modification of smoking habits. Conclusions: The most important motivations to quit smoking in this sample were an immediate reinforcement, social pressure and self control. The analysis of motivations will help to orient smoking cessation programs

ABSTRACT

Background: Effective smoking cessation campaigns require as baseline, precise estimations of smoking habits in different populations. Aim: To assess the prevalence of smoking in academic, non-academics workers and student of the University of Concepción. Material and methods: In a random and stratified sample of 272 workers (including academics) and 1146 students, a previously validated, self administered questionnaire about smoking was applied. Daily smoking was defined as smoking seven or more cigarettes per week and occasional smoking as smoking less than seven cigarettes per week. Results: The prevalence of smoking was 23 percent among academics, 34 percent among non-academic workers and 44 percent among students. Nineteen percent of men and 16 percent of women were occasional smokers; 23 percent of men and 25 percent of women were daily smokers. Students started smoking at 15 ñ 2 years old and workers did so at 18 ñ 3 years old. The grater influence about smoking came from parents. Workers from the administrative services and from the natural sciences faculty had the higher prevalence of the habit. The total annual cost of smoking was $33,000,000 (US$62,000). Conclusions: The prevalence of smoking at the University of Concepción is higher among students than workers. Quitting programs are urgently needed

ABSTRACT

La asociación fumar tabaco, beber alcohol y consumir drogas es frecuente en los adolescentes. Por esta razón estudiamos a 1.192 estudiantes recién ingresados a la Universidad de Concepción. El 40, 1 por ciento fumaba y la asociación con consumo de alcohol era 9,6 por ciento y de drogas 6,5 por ciento; mientras que en los estudiantes no fumadores era de 3,1 por ciento y 1,3 por ciento respectivamente. Los estudiantes que bebían alcohol fumaban 67,7 por ciento y los que consumían drogas 70 por ciento; mientras que la prevalencia de fumadores en los que no bebían alcohol era de 38,4 y los que no consumían drogas era de 39,1 por ciento. La asociación de consumo de alcohol y drogas fue de 3,8 por ciento en los estudiantes fumadores y 0,2 por ciento en los estudiantes no fumadores. Estos antecedentes hacen necesario implementar un programa de prevención del tabaquismo, alcohol y drogas a nivel pre-escolar y escolar; y a nivel superior otorgar oportunidades de tratamientos para dejar de fumar, beber y abandonar el consumo de drogas
