Fuchs endothelial corneal dystrophy: an updated review.

PURPOSE: The present review will summarize FECD-associated genes and pathophysiology, diagnosis, current  therapeutic approaches, and future treatment perspectives. METHODS: Literature review. RESULTS: Fuchs' endothelial corneal dystrophy (FECD) is the most common bilateral corneal dystrophy and accounts for one-third of all corneal transplants performed in the US. FECD is caused by a combination of genetic and non-heritable factors, and there are two types: early-onset FECD, which affects individuals from an early age and is usually more severe, and late-onset FECD, which is more common and typically manifests around the age of 40. The hallmark findings of FECD include progressive loss of corneal endothelial cells and the formation of focal excrescences (guttae) on the Descemet membrane. These pathophysiological changes result in progressive endothelial dysfunction, leading to a decrease in visual acuity and blindness in later stages. The present review will summarize FECD-associated genes and pathophysiology, diagnosis, current therapeutic approaches, and future treatment perspectives. CONCLUSION: With the characterization and understanding of FECD-related genes and ongoing research into regenerative therapies for corneal endothelium, we can hope to see more significant improvements in the future in the management and care of the disease.

Surgical and functional outcomes of Retzius-sparing robotic-assisted radical prostatectomy versus conventional robotic-assisted radical prostatectomy in patients with biopsy-confirmed prostate cancer. Are outcomes worth it? Systematic review and meta-analysis.

BACKGROUND: Radical prostatectomy is the standard of care for prostate cancer. Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) is being widely adopted due to positive functional outcomes compared to conventional robotic-assisted radical prostatectomy (c-RARP). Concerns regarding potency, oncological outcomes, and learning curve are still a matter of debate. METHODS: Following Preferred Instrument for Systematic Reviews and Meta-Analysis guidelines and PROSPERO registration CRD42023398724, a systematic review was performed in February 2023 on RS-RARP compared to conventional c-RARP. Outcomes of interest were continence recovery, potency, positive surgical margins (PSM), biochemical recurrence (BCR), estimated blood loss (EBL), length of stay (LOS), operation time and complications. Data were analyzed using R version 4.2.2. RESULTS: A total of 17 studies were included, totaling 2751 patients, out of which 1221 underwent RS-RARP and 1530 underwent c-RARP. Continence was analyzed using two definitions: zero pad and one safety pad. Cumulative analysis showed with both definitions statistical difference in terms of continence recovery at 1 month (0 pad odds ratio [OR] = 4.57; 95% confidence interval [CI] = [1.32-15.77]; Safety pad OR = 13.19; 95% CI = [8.92-19.49]), as well as at 3 months (0 pad OR, 2.93; 95% CI = [1.57-5.46]; Safety pad OR = 5.31; 95% CI = [1.33-21.13]). Continence recovery at 12 months was higher in the one safety pad group after RS-RARP (OR = 4.37; 95% CI = [1.97-9.73]). The meta-analysis revealed that overall PSM rates without pathologic stage classification were not different following RS-RARP (OR = 1.13; 95% CI = [0.96-1.33]. Analysis according to the tumor stage revealed PSM rates in pT2 and pT3 tumors are not different following RS-RARP compared to c-RARP (OR = 1.46; 95% CI = [0.84-2.55]) and (OR = 1.41; 95% CI = [0.93-2.13]), respectively. No difference in potency at 12 months (OR = 0.98; 95% CI = [0.69-1.41], BCR at 12 months (OR = 0.99; 95% CI = [0.46-2.16]), EBL (standardized mean difference [SMD] = -0.01; 95% CI = [-0.31 to 0.29]), LOS (SMD = -0.01; 95% CI = [-0.48 to 0.45]), operation time (SMD = -0.14; 95% CI = [-0.41 to 0.12]) or complications (OR = 0.9; 95% CI = [0.62-1.29]) were observed. CONCLUSIONS: Our analysis suggests that RS-RARP is safe and feasible. Faster continence recovery rate is seen after RS-RARP. Potency outcomes appear to be similar. PSM rates are not different following RS-RARP regardless of pathologic stage. Further quality studies are needed to confirm these findings.

Misinformation About and Interest in Chlorine Dioxide During the COVID-19 Pandemic in Mexico Identified Using Google Trends Data: Infodemiology Study.

BACKGROUND: The COVID-19 pandemic has prompted the increasing popularity of several emerging therapies or preventives that lack scientific evidence or go against medical directives. One such therapy involves the consumption of chlorine dioxide, which is commonly used in the cleaning industry and is available commercially as a mineral solution. This substance has been promoted as a preventive or treatment agent for several diseases, including SARS-CoV-2 infection. As interest in chlorine dioxide has grown since the start of the pandemic, health agencies, institutions, and organizations worldwide have tried to discourage and restrict the consumption of this substance. OBJECTIVE: The aim of this study is to analyze search engine trends in Mexico to evaluate changes in public interest in chlorine dioxide since the beginning of the COVID-19 pandemic. METHODS: We retrieved public query data for the Spanish equivalent of the term "chlorine dioxide" from the Google Trends platform. The location was set to Mexico, and the time frame was from March 3, 2019, to February 21, 2021. A descriptive analysis was performed. The Kruskal-Wallis and Dunn tests were used to identify significant changes in search volumes for this term between four consecutive time periods, each of 13 weeks, from March 1, 2020, to February 27, 2021. RESULTS: From the start of the pandemic in Mexico (February 2020), an upward trend was observed in the number of searches compared with that in 2019. Maximum volume trends were recorded during the week of July 19-25, 2020. The search volumes declined between September and November 2020, but another peak was registered in December 2020 through February 2021, which reached a maximum value on January 10. Percentage change from the first to the fourth time periods was +312.85, -71.35, and +228.18, respectively. Pairwise comparisons using the Kruskal-Wallis and Dunn tests showed significant differences between the four periods (P<.001). CONCLUSIONS: Misinformation is a public health risk because it can lower compliance with the recommended measures and encourage the use of therapies that have not been proven safe. The ingestion of chlorine dioxide presents a danger to the population, and several adverse reactions have been reported. Programs should be implemented to direct those interested in this substance to accurate medical information.

Damage Control Surgery may be a Safe Option for Severe Non-Trauma Peritonitis Management: Proposal of a New Decision-Making Algorithm.

BACKGROUND: Damage control surgery (DCS) has emerged as a new option in the management of non-traumatic peritonitis patients to increase survival in critically ill patients. The purpose of this study was to compare DCS with conventional strategy (anastomosis/ostomies in the index laparotomy) for severe non-traumatic peritonitis regarding postoperative complications, ostomy rate, and mortality and to propose a useful algorithm in the clinical practice. METHODS: Patients who underwent an urgent laparotomy for non-trauma peritonitis at a single level I trauma center in Colombia between January 2003 and December 2018, were retrospectively included. We compared patients who had DCS management versus definitive initial surgical management (DISM) group. We evaluated clinical outcomes and morbidities among groups. RESULTS: 290 patients were included; 81 patients were treated with DCS and 209 patients underwent DISM. Patients treated with DCS had a worse critical status before surgery with higher SOFA score [median, DCS group: 5 (IQR: 3-8) vs. DISM group: 3 (IQR: 1-6), p < 0.001]. The length of hospital stay and overall mortality rate of DCS group were not significant statistical differences with DISM group. Complications rate related to primary anastomosis or primary ostomy was similar. There is not difference in ostomy rate among groups. At multivariate analysis, SOFA > 6 points and APACHE-II > 20 points correlated with a higher probability of DCS. CONCLUSION: DCS in severe non-trauma peritonitis patients is feasible and safe as surgical strategy management without increasing mortality, length hospital of stay, or complications. DCS principles might be applied in the non-trauma scenarios without increase the stoma rate.

Psychiatric disorders in children and adolescents during the COVID-19 pandemic. / Trastornos psiquiátricos en los niños y adolescentes en tiempo de la pandemia por COVID-19.

INTRODUCTION: The Covid-19 pandemic has generated an unprecedented multimodal (health, occupational, economic, and social crisis, which will impact developing countries. Confinement as a preventive measure is itself a threat that produces a social impact. Pandemic and confinement have become a psychosocial adversity factor that affects families and their children. During the pandemic, children and adolescents with a psychiatric disorder may experience exacerbation of their symptoms. However, little is known about this, since studies on this population during the pandemic are scarce. OBJECTIVE: To review the data available in the current literature on the effect of the pandemic on children and adolescents with a previous psychiatric disorder. METHODS: A literature search was carried out using PubMed, Scielo and, due to the exceptional conditions of the pandemic situation, directly using internet search engines. Both English and Spanish papers were included. RESULTS: The information found is presented in the following sections: family and children during the pandemic, evaluation of mental disorders in children and young people during the pandemic, pre-existing psychiatric disorders during the pandemic, and telepsychiatric care. Specific information is presented on attention deficit hyperactivity disorder, autism spectrum disorder, intellectual disability, anxiety disorder, obsessive compulsive disorder, and post-traumatic stress disorder. The current pandemic due to COVID-19 and confinement are a psychosocial adversity that threatens the stability of the family. Such a stressor can cause exacerbation of symptoms of a previous mental disorder. Children and adolescents with psychiatric disorders are a vulnerable population and require specialised care. Telepsychiatry is becoming a modality with multiple advantages.

Trastornos psiquiátricos en los niños y adolescentes en tiempo de la pandemia por COVID-19

Introducción: La pandemia por Covid-19 ha generado una crisis multimodal inédita: sanitaria, laboral, económica, social, que repercutirá especialmente a los países en vía de desarrollo. El confinamiento como medida preventiva es su vez una amenaza que producen un impacto social. Pandemia y confinamiento se han convertido en un factor de adversidad psicosocial que afecta las familias y sus hijos. Durante la pandemia, los niños y adolescentes con un trastorno psiquiátrico podrían presentar exacerbación de sus síntomas. Sin embargo, poco se conoce al respecto, pues los estudios sobre esta población durante la pandemia son escasos. Objetivo: Revisar los datos disponibles en la literatura actual acerca del efecto de la pandemia sobre los niños y adolescentes que presentan un trastorno psiquiátrico previo. Métodos: Se realizó una búsqueda de la literatura a través de PubMed, Scielo y, por las condiciones excepcionales de la situación de pandemia, de manera directa en buscadores de internet. Se incluyeron artículos en ingles y español. Resultados: La información encontrada se presenta en los siguientes apartados: la familia y los hijos durante la pandemia, evaluación de los trastornos mentales en niños y jóvenes durante la pandemia, trastornos psiquiátricos preexistentes durante la pandemia, y atención en telepsiquiatría. Se presenta información específica sobre el trastorno por déficit de atención e hiperactividad, trastorno del espectro autista, discapacidad intelectual, trastorno de ansiedad, trastorno obsesivo compulsivo y el trastorno por estrés postraumático. La pandemia actual por COVID-19 y el confinamiento son una adversidad psicosocial que atenta contra la estabilidad de la familia. Tal estresor pude causar exacerbación de los síntomas de un trastorno mental previo. Los niños y adolescentes con trastornos psiquiátricos son una población vulnerable que requiere de una atención especializada. La telepsiquiatría se convierte en una modalidad con múltiples ventajas.

In NPH, setting valve opening pressure close to lumbar puncture opening pressure decreases overdrainage.

BACKGROUND: The management of normal pressure hydrocephalus (NPH) can be difficult, partly because there are frequent treatment complications such as overdrainage which, when serious, may require surgical intervention. We previously reported a correlation between the difference of lumbar puncture opening pressure minus the valve opening pressure setting (LPOP-VOP) (which we refer to as the delta) and increased rates of overdrainage. This led to a modification in our practice, whereby we now set the VOP equal to, or close to, the LPOP, resulting in lower deltas. OBJECTIVE: In this new study, our aim was to compare the rate of overdrainage in our patients with higher and lower deltas and assess the significance of setting the VOP equal, or close, to the patient's LPOP. METHODS: 1. We reproduced the association between delta and overdrainage. 2. We compared the incidence of overdrainage in those whose VOP was set close to LPOP (low delta) versus those with VOP setting distant from the LPOP (higher delta). 3. We compared symptom improvement in those with a low versus higher delta. RESULTS: We confirmed the relation between high delta and an increased rate of overdrainage, lower rates of overdrainage in those whose VOP was set close to the LPOP (Delta Adjusted Practice), and better improvement of symptoms when the VOP was set closer to the LPOP. CONCLUSION: We propose that the initial VOP should be set as close as possible to the patient's LPOP to decrease overdrainage without compromising symptom improvement.

Resuscitative endovascular balloon of the aorta is feasible in penetrating chest trauma with major hemorrhage: Proposal of a new institutional deployment algorithm.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging option for hemorrhage control, but its use is limited in scenarios such as penetrating chest trauma. The aim of this study was to describe the use of REBOA as a resuscitative adjunct in these cases with major hemorrhage and to propose a new clinical management algorithm. METHODS: This was a prospective, observational study conducted at a single Level I trauma center in Colombia. We included all patients older than 14 years with severe trauma who underwent REBOA from January 2015 to December 2019. Patients received REBOA if they were in hemorrhagic shock and were unresponsive to resuscitation. RESULTS: A total of 56 patients underwent REBOA placement of which 37 had penetrating trauma and 23 had chest trauma. All patients were hemodynamically unstable upon arrival to the emergency department, with a median systolic blood pressure of 69 mm Hg (interquartile range [IQR], 57-90 mm Hg) and median Injury Severity Score was 25 (IQR, 25-41). All REBOAs were deployed and inflated in zone 1, median inflation time was 40 minutes (IQR, 26-55 minutes), and no adverse neurologic outcomes were observed. Fifteen patients had REBOA and a median sternotomy. Eleven patients had concomitant abdominal wounds. Overall mortality was 28.6%, and there was no significant difference between penetrating versus blunt trauma patients (21.6% vs. 42.1%, p = 0.11). The survival rate of thoracic injured patients was similar to the predicted survival (65.2% vs. 63.3%). CONCLUSION: Resuscitative endovascular balloon occlusion of the aorta can be used safely in penetrating chest trauma, and the implementation of a REBOA management algorithm is feasible with a well-trained multidisciplinary team. LEVEL OF EVIDENCE: Therapeutic, level V.

Uso de la tomografía corporal total en pacientes con trauma grave: ¿es efectiva y segura para definir el manejo no operatorio? / Use of total body tomography in patients with severe trauma: is it effective and safe to define non-operative management?

Introducción. La tomografía corporal (TC) total en la evaluación de pacientes con trauma grave, puede ser una herramienta eficaz y segura para decidir entre un tratamiento quirúrgico y uno no quirúrgico, pero aún no son claras las implicaciones diagnósticas y los riesgos asociados con esta técnica.Métodos. Se incluyeron pacientes mayores de 15 años con trauma grave que fueron sometidos a TC total. Se evaluaron la seguridad, la efectividad y la eficiencia por medio de los parámetros de incidencia de nefropatía inducida por los medios de contraste, dosis total de radiación por paciente, proporción de casos en los que la TC total cambió el manejo, y el retraso en el diagnóstico. Resultados. Se incluyeron 263 pacientes, 83 % sufrieron trauma cerrado y 17 % sufrieron trauma penetrante. La gravedad de la lesión fue mayor en estos últimos y, sin embargo, el trauma cerrado con inestabilidad hemodinámica se presentó con mayores grados de choque. El 65 % de los pacientes recibió tratamiento selectivo no operatorio. Entre los subgrupos, no hubo diferencias significativas en el tiempo entre el ingreso a la sala de urgencias y la toma de la TC total (p=0,96) y, en la mayoría de los casos, el tiempo entre la práctica de la TC total y el diagnóstico de presencia o ausencia de heridas fue menor de 25 minutos. La mediana de radiación total estuvo por debajo de 20 mSv en todos los grupos. No hubo diferencias significativas en la mortalidad (p=0,17). Conclusión. La TC total es una herramienta segura y eficiente para decidir entre un tratamiento quirúrgico y uno no quirúrgico en los casos de trauma grave, independientemente del mecanismo de la lesión o la estabilidad hemodinámica al ingreso

Introduction: Total body tomography (CT) in the evaluation of patients with severe trauma may be an effective and safe tool to decide between a surgical or non-operative management, but the diagnostic implications and risks associated with this technique are still unclear.Methods: Patients older than 15 years with severe trauma who underwent total CT were included. Safety, effectiveness and efficiency were evaluated through the parameters of incidence of contrast-induced nephropathy, total radiation dose per patient, proportion of cases in which the total CT changed the management, and the delay in the diagnosis.Results: 263 patients were included, 83% presented with blunt trauma and 17% with penetrating trauma. The severity of the injury was higher in the latter, however, the blunt trauma with hemodynamic instability presented with higher degrees of shock. Non-operative management was selected in 65% of patients. Among the subgroups, there was no significant difference in the time between admission to the emergency room and taking the total CT (p=0.96), and in most cases, the time between the total CT and the diagnosis of presence or absence of injury was less than 25 minutes. The median total radiation was below than 20 mSv in all groups. There were no significant difference in mortality (p=0.170. Conclusion: Total CT is a safe and efficient tool to decide between a surgical and a non-operative management in patients with severe trauma, regardless of the mechanism of injury or hemodynamic stability at admission

Cuidados paliativos al final de la vida en pacientes con demencia terminal / End-of-life palliative care in patients with terminal dementia

Resumen La demencia es condición que típicamente involucra un deterioro gradual y progresivo de la cognición, el comportamiento y el funcionamiento de un individuo, hasta alcanzar la muerte. La medicina paliativa asiste a pacientes que enfrentan procesos degenerativos progresivos como este y les provee insumos para mejorar su calidad de vida, aliviar su dolor y apoyar a quienes les asisten; en una forma interdisciplinaria e integral hasta el final de su vida. Este trabajo pretende exponer brevemente, mediante una revisión de literatura vigente, el conocimiento y teorías actuales sobre demencia como una condición terminal que requiere atención paliativa; desde una perspectiva integral, enfocándose en el manejo y los objetivos de cuidado del paciente con esta condición, que reúna tanto la visión médica como la del paciente, su red de apoyo y su entorno. Se describe la demencia como una condición terminal que requiere de atención paliativa desde el momento de su diagnóstico, las necesidades propias del paciente con esta condición y las implicaciones de su atención, requiriendo un abordaje integral y un planteamiento de objetivos claros, humanizados y centrados en el paciente; que satisfacen sus necesidades, consideran y respetan su individualidad y contemplan aspectos como la voluntad adelantada.

Abstract Dementia is a condition that typically involves a gradual and progressive deterioration of the cognition, behavior and functioning of an individual, to death. Palliative medicine assists patients who face progressive degenerative processes like this one and provides them with supplies to improve their quality of life, relieve their pain and support those who assist them; in an interdisciplinary and integral way until the end of his life. This work aims to briefly expose, through a review of current literature, knowledge and current theories about dementia as a terminal condition that requires palliative care; from a holistic perspective, focusing on the management and objectives of patient care with this condition, which brings together both the medical and the patient's vision, their support network and their environment. Dementia is described as a terminal condition that requires palliative care from the moment of diagnosis, the specific needs of the patient with this condition and the implications of their care, requiring a comprehensive approach and a clear, humanized and patient-centered approach to goals of care; that meet their needs, consider and respect their individuality and contemplate aspects such as their advanced wills.

Control prehospitalario de la hemorragia en pacientes de trauma: una estrategia de prevención secundaria factible para países de bajos y medianos ingresos / Prehospital control of hemorrhage in trauma patients: a feasible secondary prevention strategy in countries of low and median income

Introducción. La hemorragia no controlada es la principal causa prevenible de muerte en trauma. No hay precedentes locales que estimen el efecto de estrategias de prevención que involucren al público en la atención inicial de las víctimas. Objetivo. Evaluar si es factible implementar programas de entrenamiento para el control prehospitalario básico del sangrado en pacientes de trauma, en un país de bajos a medianos ingresos. Métodos. Cirujanos y estudiantes de medicina se encargaron de desplegar el curso "Stop the bleed" en estudiantes universitarios del suroccidente colombiano. Se hizo una evaluación antes y después de hacer el entrenamiento. Se usó la prueba t de Student y un análisis de regresión logística ordinal, para determinar los factores que estuvieron asociados a obtener mejores puntajes en la evaluación del curso. Resultados. Se entrenaron 265 estudiantes, con una edad media de 21,4 ± 4 años, de los cuales 136 (51,5 %) eran mujeres. Después de recibir el entrenamiento un participante tuvo 15,6 veces la oportunidad de obtener mayor puntaje de calificación con respecto al periodo preentrenamiento [IC95%: 15,1-16,2 (p<0,001)], 99,4 y 95,2 %, respectivamente, estarían dispuestos a tomar medidas y colocar un torniquete a una víctima de sangrado (p<0,001). Conclusión. Es factible para los países con recursos limitados hacer el entrenamiento en control básico del sangrado. Este se puede llevar a cabo de manera eficaz, tanto por instructores con un bagaje amplio en técnicas de control del sangrado como por instructores con menor nivel de formación, pero con un entrenamiento adecuado

Background: uncontrolled hemorrhage is the leading cause of preventable death in trauma. There are no local precedents that estimate the effect of prevention strategies that involve the public in the initial care of victims. Our objective was to evaluate if it is feasible to implement training programs for the basic control of prehospital bleeding in trauma patients, in a low to a middle-income country. Methods: Surgeons and medical students deploying the Stop the bleed course in a Colombian southwestern university, evaluation was performed before and after the training. A T-test and an ordinal logistic regression analysis were used to determine the factors associated with better scores in the course evaluation. Results: of the 265 students, were women 136 (51.5%), age was 21.4± 4. After receiving the training, a participant had 15.6 times the chance of obtaining a higher score than the pre-training period [95% CI: 15.1-16.2 (p <0.001)]. 99.4% and 95.2% respectively, would be willing to take actions and place a tourniquet on a bleeding victim (p <0.001). Conclusion: in a low to a middle-income country is feasible to perform the Bleeding Control Basic training. This can be done effectively by instructors with a broad background in bleeding control techniques as well as by instructors with less experience, but with adequate training

Analysis of combat casualties admitted to the emergency department during the negotiation of the comprehensive Colombian process of peace / Análisis de los soldados heridos en combate admitidos al departamento de emergencias durante la negociación del proceso de paz en Colombia

Abstract Aim: Our objective was to describe the variations in casualties admitted to the emergency department during the period of the negotiation of the comprehensive peace agreement in Colombia between 2011 and 2016. Methods: A retrospective study of all hostile military casualties managed at a regional Level I trauma center from January 2011 to December 2016. Patients were subsequently divided into two groups: those seen before the declaration of the process of peace truce (November 2012) and those after (negotiation period). Variables were compared with respect to periods Results: A total of 448 hostile casualties were registered. There was a gradual decline in the number of admissions to the emergency department during the negotiation period. The number of soldiers suffering blast and rifle injuries also decreased over this period. In 2012 there were nearly 150 hostile casualties' admissions to the ER. This number decreased to 84, 63, 32 and 6 in 2013, 2014, 2015 and 2016 respectively. Both, the proportion of patients with an ISS ≥9 and admitted to the intensive care unit were significantly higher in the period before peace negotiation. From August to December/2016 no admissions of war casualties were registered. Conclusion: We describe a series of soldiers wounded in combat that were admitted to the emergency department before and during the negotiation of the Colombian process of peace. Overall, we found a trend toward a decrease in the number of casualties admitted to the emergency department possibly in part, as a result of the period of peace negotiation.

Resumen Objetivo: Describir las variaciones en los soldados heridos en combate admitidos al departamento de emergencias durante el periodo de negociación del proceso de paz colombiano entre el 2011 y el 2016. Métodos: Estudio retrospectivo de todos los soldados heridos en combate que fueron manejados en un centro de trauma desde Enero del 2011 a Diciembre del 2016. Los pacientes se dividieron en dos grupos: aquellos que ingresaron al departamento de emergencias antes de la tregua del proceso de paz (Noviembre 2012) y aquellos que ingresaron durante la negociación. Los grupos se compararon con respecto a los periodos de tiempo. Resultados: Un total de 448 soldados heridos en combate fueron incluidos. Hubo una disminución gradual en el número de admisiones durante el periodo de negociación. Además, el número de soldados que sufrieron heridas por explosiones y fusiles disminuyó durante este periodo. En el 2012 se registraron 150 soldados heridos en combate. Este número disminuyó a 84, 63, 32 y 6 en los años 2013, 2014, 2015 y 2016 respectivamente. La proporción de pacientes con un ISS ≥9 y la proporción de admitidos a la unidad de cuidado intensivo fueron significativamente mayores en el periodo antes de la negociación. Desde Agosto a Diciembre/2016 no se registraron admisiones. Conclusión: Este estudio describe una disminución gradual en el número de soldados heridos en combate admitidos al departamento de emergencia en un periodo de 6 años. Este fenómeno pudo deberse al periodo de negociación del proceso de paz.

A meta-analysis of resuscitative endovascular balloon occlusion of the aorta (REBOA) or open aortic cross-clamping by resuscitative thoracotomy in non-compressible torso hemorrhage patients.

BACKGROUND: The objective of this systematic review and meta-analysis was to determine the effect of REBOA, compared to resuscitative thoracotomy, on mortality and among non-compressible torso hemorrhage trauma patients. METHODS: Relevant articles were identified by a literature search in MEDLINE and EMBASE. We included studies involving trauma patients suffering non-compressible torso hemorrhage. Studies were eligible if they evaluated REBOA and compared it to resuscitative thoracotomy. Two investigators independently assessed articles for inclusion and exclusion criteria and selected studies for final analysis. We conducted meta-analysis using random effect models. RESULTS: We included three studies in our systematic review. These studies included a total of 1276 patients. An initial analysis found that although lower in REBOA-treated patients, the odds of mortality did not differ between the compared groups (OR 0.42; 95% CI 0.17-1.03). Sensitivity analysis showed that the risk of mortality was significantly lower among patients who underwent REBOA, compared to those who underwent resuscitative thoracotomy (RT) (RR 0.81; 95% CI 0.68-0.97). CONCLUSION: Our meta-analysis, mainly from observational data, suggests a positive effect of REBOA on mortality among non-compressible torso hemorrhage patients. However, these results deserve further investigation.

Trauma Pancreático Penetrante Severo-Revisión Retrospectiva de Una Serie de Casos Manejados Con Una Estrategia Simplificada en un Centro de Trauma Nivel 1.

Introduction: Pancreatic trauma has a low incidence in both closed and penetrating injuries. The risk for morbidity and mortality is associated with injury severity of multiple organ injuries. Objective: To describe the characteristics of patients with penetrating pancreatic trauma treated at Foundation Valle del Lili (FVL), analyze the treatment performed and possible variables associated with the occurrence of complications related to injury to the pancreas and its treatment. Materials and methods: A retrospective review was made. The medical records of patients with abdominal trauma penetrating with pancreatic injury seen in FVL between 2000 and 2013, and who survived more than 48 hours. We analyzed demographic variables, severity of trauma and management related to the development of pancreatic fistula. Results: Twenty-eight patients were identified with median age 30 years (21-38). Eight (28%) were admitted in shock (SBP <90 mm Hg). The anatomical severity measured by the PATI had median 50 (34.5-67.5). The number of organs injured: a median of 5 (5-6). Twenty-one patients (75%) had major vascular injuries, 19 (68%) gastric injury, 14 (50%) colon, 12 (43%) liver, small intestine 12 and 11 (39%) duodenal. The severity of pancreatic injury was a median of 3 (2-4). Treatment of pancreatic lesion consisted of suture in 12 cases (42.8%), distal resection in 8 (28.6%) and packing in 8. Local complications occurred in 23 patients (83%), abdominal sepsis in 19 (68%), pancreatic fistula in eight (29%) and intestinal fistula in six (21%). Four patients (14%) died, two from sepsis and two from multiorgan failure. No association was found between severity of trauma or damaged organs and the risk of fistula. Only pancreatic suture was associated with lower risk of complication. Comment: We present a series of patients with penetrating pancreatic trauma with a high prevalence of serious injuries and associated morbidity, despite which mortality was reduced. Simple suture of the pancreatic injury was associated with lower risk of fistula.

Introducción: El trauma de páncreas, tiene una baja incidencia tanto en heridas penetrantes como cerradas y se asocia a múltiples lesiones de órganos que determinan la severidad del trauma y el riesgo de morbilidad y mortalidad. Objetivo: Describir las características de los pacientes con trauma pancreático penetrante atendidos en a Fundación Valle del Lili (FVL), analizar el tratamiento realizado y las posibles variables asociadas a la ocurrencia de complicaciones relacionadas con la lesión del páncreas y dicho tratamiento. Materiales y métodos: Se hizo una revisión retrospectiva de las historias clínicas de los pacientes con trauma abdominal penetrante con lesión de páncreas, manejados completamente en la FVL entre 2000 y 2013, que sobrevivieron más de 48 horas. Se analizaron variables demográficas, de la severidad del trauma y del manejo, relacionadas con el desarrollo de fístula pancreática. Resultados: Se identificaron 28 pacientes con mediana de edad 30 años, (RIQ 21­38). Ocho, (28%) ingresaron en shock (TAS <90 mm Hg).La severidad anatómica medida por el PATI tuvo una mediana de 50 (RIQ 34,5­67,5). El número de órganos lesionados una mediana de 5 (RIQ 5­6).21 pacientes (75%) tuvieron lesiones vasculares mayores o menores, 19 (68%) compromiso gástrico, 14 (50%) colónico, 12 (43%) hepático, 12 de intestino delgado, 12 vascular mayor y 11 (39%) duodenal. La severidad de la lesión pancreática tuvo una mediana de 3 con RIQ de 2 a 4.El tratamiento de la lesión pancreática consistió en sutura en 12 casos (42.8%), resección distal en 8 (28.6%) o empaquetamiento en 8.Se presentaron complicaciones locales en 23 pacientes (83%). Sepsis abdominal en 19 (68%), fístula pancreática en 8 (29%) y fístula intestinal en 6 (21%).Cuatro pacientes (14%) murieron. Dos por sepsis y dos por falla multiorgánica. No se encontró asociación entre la severidad del trauma o los órganos lesionados y el riesgo de fístula. Solamente la sutura del páncreas se asoció con menor riesgo de la complicación. Comentario: Presentamos una serie de pacientes con trauma pancreático penetrante con una alta prevalencia de lesiones asociadas graves que determinaron una morbilidad considerable, a pesar de lo cual la mortalidad fue reducida. La sutura de la lesión pancreática se asoció con menor riesgo de fístula.

A complication of soft tissue graft tibial fixation with the IntraFix device.

BACKGROUND: One potential complication of interference devices to fix anterior cruciate ligament (ACL) grafts is divergence between the implant and the graft-tunnel. Tunnel-screw divergence >15-30 degrees significantly reduces graft-tunnel fixation and may compromise the stability of the knee. CASE REPORT: A complication of the IntraFix device is presented. A 43-year-old male sustained a primary ACL reconstruction. The autologous hamstring graft was fixed in the tibia with the IntraFix device. The procedure went without apparent incidents or complications. During postoperative follow-up he developed pain and crepitus over the anteromedial aspect of the operated knee. A flexion contracture slowly developed up to 10 degrees and did not improve with aggressive physiotherapy. At eight postoperative weeks, second-look arthroscopy was performed. The intraoperative findings were a healthy-looking ACL graft and a grade III chondral injury in the medial femoral condyle (MFC) caused by the tip of the IntraFix device, which protruded through the medial tibial plateau. During flexion-extension motion of the knee, the tip eroded the chondral surface of the MFC. This was treated with mechanical and thermal chondroplasty and the tip of the IntraFix device was burred flat to match the surface of the medial tibial plateau. The patient's symptoms improved. CONCLUSIONS: Divergence of the interference screws in the femur is not uncommon, but on the tibia it is rare. Although this technical error did not affect stability, it did produce intrarticular injury. Strict adherence to the surgical technique is recommended and several hints on how to avoid complications with this implant are suggested.

Prostitución masculina: ¿venta o placer? / Male Prostitution: sale or pleasure?

La prostitución es considerada como la práctica más antigua de vender o cambiar el cuerpo por dinero, y aunque no se crea, en muchos casos es una elección propia, para mantener y elevar el nivel de vida aunque culturalmente se continúa pensando que el hecho de ejercer la prostitución es un asunto relacionado con las necesidades económicas de quienes se dedican a ella.

Prostitution is considered as the oldest practice of selling or exchanging the body for money, and although it is not created, in many cases it is a choice of its own, to maintain and raise the standard of living although culturally it is still thought that the act of exercising Prostitution is a matter related to the economic needs of those who are dedicated to it.

Implementación del método del cálculo de vulnerabilidad sísmica de edificios en un sistema de información geográfica

El objetivo general del trabajo es administrar información sobre peligro sísmico mediante un sistema de información geográfica (SIG) que permitan obtener resultados que describan la vulnerabilidad y el riesgo que existe en el noroeste de México. Existen varios estudios científicos de aplicación de SIG al cálculo del riesgo sísmico en diversas partes del mundo. Se pretende emplear algunas metodologías y aplicarlas en la región del noroeste de México, para ello se hará un análisis de los SIG existentes, se diseñará en sistema adecuado a las características regionales y requerimientos de información de los usuarios. El sistema contemplará la vulnerabilidad de las principales estructuras existentes, edificios, hospitales, puentes y en una primera etapa se implementará el método para el cálculo de vulnerabilidad sísmica de edificios. Este sistema representará un beneficio importante para la sociedad, ya que servirá de apoyo a las autoridades en la toma de decisiones referentes a la planeación urbana, prestación de servicios, protección civil, prevención de desastres, atención posterremotos, entre otras.

Semi-quantitative PCR: A tool to study low abundance messages in the kidney

Some specific functions are often localized to unique cellular types or structures in organs such as kidney, brain, blood, and endocrine glands. As a result, it is not ucommon that gene producta, although heavily expressed in some cell type within these organs, ultimately appear as low abundance products when total RNA is probed, resulting in decreased power of the conventional Northern blot analysis. To study gene expression in these circumstances, more sensitive techniques like RNAse protection assay and quantitative or semi-quantitative PCR strategies have been developed. In the present study, we provede a detailed descriptio of the semiquantitative PCR strategy in our laboratory. Using specific primers to amplify fragments from the neuronal isoform of the nitric oxide synthase and the thiazide-sensitive Na+:Cl- contransporter (low abundance messages in the kidney), we show that the semi-quantitative PCR strategy is a valuable tool when low abundance messages are to be studied
