[Dengue, chikungunya and the mosquito vector at the Southern limit of distribution during the 2023 epidemic, Argentina]. / Dengue, chikungunya y el mosquito vector en el límite sur de distribución durante la epidemia 2023, Argentina.

OBJECTIVES: To monitor the oviposition activity of the mosquito Aedes aegypti and of dengue and chikungunya cases in four localities of temperate Argentina, during the 2023 epidemic. METHODS: During the summer and autumn of 2023, the oviposition activity of the mosquito vector was monitored weekly using ovitraps, and the arrival of cases with dengue or chikungunya in Tandil, Olavarría, Bahía Blanca and Laprida were registered. RESULTS: Monthly variations of the percentage of positive traps were similar in the first three locations; in Laprida the mosquito was not detected. On the contrary, a significant difference was observed in the percentage of total traps that ever tested positive in each locality, being higher in Olavarría (83.3%) than in Bahía Blanca (68.6%) and Tandil (48.7%). Regarding diseases, 18 imported cases of dengue and 3 of chikungunya were registered. In addition, the first autochthonous case of dengue in the region was recorded, being the southernmost until known. CONCLUSION: It is essential to raise awareness and train the members of the health systems of the new regions exposed to Ae. aegypti for early detection of cases, and to the general population to enhance prevention actions.

OBJETIVOS: Monitorear la actividad de oviposición del mosquito Aedes aegypti y de casos de dengue y chikungunya en cuatro localidades de Argentina templada, durante la epidemia del 2023. Métodos: Durante el verano y otoño del 2023, se monitoreó semanalmente mediante ovitrampas la actividad de oviposición del mosquito vector, y se registró el arribo de casos con dengue o chikungunya a Tandil, Olavarría, Bahía Blanca y Laprida. RESULTADOS: La variación mensual del porcentaje de trampas positivas fue similar en las tres primeras localidades; en Laprida no se detectó el mosquito. Por el contrario, se observó una diferencia significativa del porcentaje de trampas que alguna vez resultó positiva en cada localidad, siendo mayor en Olavarría (83%), que en Bahía Blanca (67%) y Tandil (49%). Respecto a las enfermedades, se registraron 18 casos importados de dengue y 3 de chikungunya. Además, se registró el primer caso autóctono de dengue en la región, siendo el más austral hasta el momento. Conclusión: Es imprescindible sensibilizar y capacitar a los integrantes de los sistemas de salud de las nuevas regiones expuestas al Ae. aegypti para la detección temprana de casos, y a la población en general para potenciar las acciones de prevención.

[Detection of adverse events in patients interned in medical clinic using the Global Trigger Tool]. / Detección de eventos adversos en pacientes internados en clínica médica utilizando la herramienta Global Trigger Tool.

INTRODUCTION: The Global Trigger Tool (GTT) is a tool that accurately identifies adverse events that represent a significant problem in hospitals. METHODS: Cross-sectional study based on retrospective review of randomized medical records using the GTT tool. RESULTS: A total of 161 adverse events (AEs) were detected: 51 events per 100 admissions, 66 per 1000 patient-days, and 30% of admissions with AEs. The most frequent triggers were from the care module, with 25% complications associated with the use of procedures, 10% pressure ulcers, and 9% care-associated infections. The presence of AEs had a statistically significant association with a stay of more than 5 days, and a moderate association with age and number of triggers. Regarding the damage, 78% of the patients presented mild events and 4% fatal events. The ROC curves analysis showed that the triggers with the greatest area under the curve were: procedural complication (0.70), pressure ulcers (0.61) and rapid response code (0.60). DISCUSSION: The number of events per 100 admissions was higher than that reported in the literature, but there were no differences in events per 1000 patientdays. Fatal cases were caused by respiratory infectious diseases in patients with comorbidities, nasogastric tube needs and cognitive decline. The study highlights the scarce use of the tool in public hospitals and the implementation of trigger analysis with ROC curves. Knowing the frequency and the most frequent type of event will allow the implementation of measures that improve patient safety.

Introducción: El Global Trigger Tool (GTT) es una herramienta que identifica con precisión los eventos adversos, estos representan un problema relevante y prevenible en los hospitales. Métodos: Estudio de corte transversal basado en la revisión retrospectiva de historias clínicas aleatorizadas utilizando el GTT. Resultados: Se detectaron 161 eventos adversos (EA): 51 por cada 100 admisiones, 66 por cada 1000 días paciente y 30% de admisiones con EA. Los disparadores más frecuentes fueron del módulo cuidados, 25% complicaciones asociadas al uso de procedimientos, 10% úlceras por presión y 9% infecciones asociadas a la atención. La presencia de EA tuvo asociación estadísticamente significativa con estancia mayor a 5 días, y asociación moderada con edad y número de disparadores. En cuanto al daño, 78% de los pacientes presentaron eventos leves y 4% eventos fatales. En el análisis con curvas ROC, los disparadores con mayor área bajo la curva fueron: complicación de procedimientos (0.70), úlceras por presión (0.61) y código de respuesta rápida (0.60). Discusión: Los eventos por 100 admisiones fueron superiores a la bibliografía pero no hubo diferencias en eventos por cada 1000 días paciente. Los casos fatales se produjeron por enfermedades infecciosas respiratorias en pacientes con comorbilidades, necesidad de sonda nasogástrica y deterioro cognitivo. Se destaca la escasa aplicación de la herramienta en hospitales públicos, y la implementación de análisis de disparadores con curvas ROC. Conocer la frecuencia y el tipo de evento más frecuente permitirá implementar medidas que mejoren la seguridad de los pacientes.

El trasplante pulmonar en la fibrosis quística y la influencia de la circulación extracorpórea / Lung Transplantation in Cystic Fibrosis and the Impact of Extracorporeal Circulation

Introducción: La enfermedad pulmonar es la principal causa de mortalidad en el 80% de los pacientes con fibrosis quística (FQ). La influencia de la circulación extracorpórea (CEC) no está completamente establecida. Los objetivos son evaluar los resultados del trasplante pulmonar por FQ en un solo centro y la influencia de la CEC sobre la supervivencia de estos pacientes. Métodos: Estudio observacional retrospectivo de todos los pacientes afectados de FQ trasplantados en un solo centro entre 1992 y 2011. En este período se han realizado 64 trasplantes pulmonares por FQ. Resultados: La supervivencia de los pacientes trasplantados a los 5 y 10 años fue del 56,7 y el 41,3%, respectivamente. El requerimiento de oxígeno suplementario previo al trasplante no parece afectar a la supervivencia (p = 0,44), al igual que los pacientes que se trasplantaron con ventilación mecánica no invasiva (p = 0,63). La supervivencia a los 5 y 10 años para los pacientes que no se trasplantan con CEC es del 75,69 y el 49,06%, respectivamente, mientras que los que se trasplantan bajo CEC tienen un supervivencia a los 5 y 10 años del 34,14 y el 29,87%, respectivamente (p = 0,001). La PaCO2 es un factor de riesgo independiente para la necesidad de CEC. Conclusiones: Los pacientes con FQ trasplantados pulmonares en nuestro centro tiene una supervivencia similar a la descrita por los registros internacionales. Los pacientes trasplantados bajo CEC tienen una menor supervivencia. La PaCO2 es factor de riesgo de necesidad de CEC durante el trasplante pulmonar

Introduction: Lung disease is the major cause of death among cystic fibrosis (CF) patients, affecting 80% of the population. The impact of extracorporeal circulation (ECC) during transplantation has not been fully clarified. This study aimed to evaluate the outcomes of lung transplantation for CF in a single center, and to assess the impact of ECC on survival. Methods: We performed a retrospective observational study of all trasplanted CF patients in a single center between 1992 and 2011. During this period, 64 lung transplantations for CF were performed. Results: Five- and 10-year survival of trasplanted patients was 56.7% and 41.3%, respectively. Pre-transplantation supplemental oxygen requirements and non-invasive mechanical ventilation (NIMV) do not seem to affect survival (P=.44 and P=.63, respectively). Five- and 10-year survival among patients who did not undergo ECC during transplantation was 75.69% and 49.06%, respectively, while in those did undergo ECC during the procedure, 5- and 10-year survival was 34.14% and 29.87%, respectively (P=.001). PaCO2 is an independent risk factor for the need for ECC. Conclusions: The survival rates of CF patients undergoing lung transplantation in our hospital are similar to those described in international registries. Survival is lower among patients receiving ECC during the procedure. PaCO2 is a risk factor for the need for ECC during lung transplantation

10 years of prophylaxis with nebulized liposomal amphotericin B and the changing epidemiology of Aspergillus spp. infection in lung transplantation.

The aim of this study was to assess the outcome and tolerability of prophylactic nebulized liposomal amphotericin B (n-LAB) in lung transplant recipients (LTR) and the changing epidemiology of Aspergillus spp. infection and colonization. We performed an observational study including consecutive LTR recipients (2003-2013) undergoing n-LAB prophylaxis lifetime. A total of 412 patients were included (mean postoperative follow-up 2.56 years; IQR 1.01-4.65). Fifty-three (12.8%) patients developed 59 Aspergillus spp. infections, and 22 invasive aspergillosis (overall incidence 5.3%). Since 2009, person-time incidence rates of Aspergillus spp. colonization and infection decreased (2003-2008, 0.19; 2009-2014, 0.09; P = 0.0007), but species with reduced susceptibility or resistance to amphotericin significantly increased (2003-2008, 38.1% vs 2009-2014, 58.1%; P = 0.039). Chronic lung allograft dysfunction (CLAD) was associated with Aspergillus spp. colonization and infection (HR 24.4, 95% CI 14.28-41.97; P = 0.00). Only 2.9% of patients presented adverse effects, and 1.7% required discontinuation. Long-term administration of prophylaxis with n-LAB has proved to be tolerable and can be used for preventing Aspergillus spp. infection in LTR. Over the last years, the incidence of Aspergillus spp. colonization and infection has decreased, but species with reduced amphotericin susceptibility or resistance are emerging. CLAD is associated with Aspergillus spp. colonization and infection.

Complicación de colecistectomía laparoscópica no publicada / Complication of laparoscopic cholecystectomy unpublished

Introducción: Las complicaciones de la cirugía laparoscópica son una nueva entidad nosológica de fines del siglo XX, desde el inicio de la misma se han publicado múltiples complicaciones desde leves hasta graves, incluso con muerte de los pacientes. Objetivo: Presentación de un caso clínico. Caso Clínico: Paciente femenino de 48 años, se realizó colecistectomía laparoscópica en sanatorio privado con técnica americana sin complicaciones. 14 meses después consulta a nuestro hospital por dolores abdominales de tipo punzante, sin otro tipo de sintomatología, antecedente de 4 cesáreas y eventración media infraumbilical. Se solicita radiografía de abdomen y TAC. Se evidencia oblito quirúrgico, se decide la intervención quirúrgica, laparotomía media infraumbilical. Hallazgo: mandril de aguja de Verres. Buena evolución con alta a las 72 hs. Discusión: No se halló reporte sobre la posibilidad que el mandril de una aguja descartable se desprenda y quede dentro de la cavidad abdominal. Numerosos trabajos avalan la no utilización de la aguja de Verres para el neumoperitoneo, y aconsejan la utilización de la técnica de Hasson o mini-laparotomía, o los sistemas tipo optic-view para el ingreso de la cavidad.

Introduction: Complications of laparoscopic surgery are a new entity of the late twentieth century, from the beginning of the century have been published multiple complications, from mild to severe, even death of the patients. Objective: Presentation of a clinical case. Case report: Female aged 48, with a history of laparoscopic cholecystectomy in a private hospital 14 months ago with no complications, consulted our hospital with sharp abdominal pain, no other symptoms, with history of two caesarean sections and a infraumbilical eventration. CT and radiography is requested. Evidenced surgical oblito, deciding surgical intervention, infraumbilical laparotomy. Finding: Verres needle mandrel. Patient is discharged 72 hs later. Discusion: We found no report on the possibility that verres needle mandrel discards and remain in the abdominal cavity. Numerous studies support the non use of the Verres needle for the pneumoperitoneum and advise the use of Hasson technique or mini-laparoscopy, as well as the optic-view systems.

Early and mid-term results of lung transplantation with donors 60 years and older.

OBJECTIVES: There are doubts about the age limit for lung donors and the ideal donor has traditionally been considered to be one younger than 55 years. The objective of this study was to compare the outcomes in lung transplantation between organs from donors older and younger than 60 years. METHODS: We performed a retrospective observational study comparing the group of patients receiving organs from donors 60 years or older (Group A) or younger than 60 years (Group B) between January 2007 and December 2011. Postoperative evolution and mortality rates, short-term and mid-term postoperative complications, and global survival rate were evaluated. RESULTS: We analysed a total of 230 lung transplants, of which 53 (23%) involved lungs from donors 60 years of age or older (Group A), and 177 (77%) were from donors younger than 60 years (Group B). Three (5.7%) patients from Group A and 14 patients (7.9%) from Group B died within 30 days (P = 0.58). The percentage of patients free from chronic lung allograft dysfunction at 1-3 years was 95.5, 74.3 and 69.3% for Group A, and 94.5, 84.8 and 73.3% for Group B, respectively (P = 0.47). There were no statistically significant differences between Groups A and B in terms of survival at 3 years, (69.4 vs 68.8%; P = 0.28). CONCLUSIONS: Our results support the idea that lungs from donors aged 60-70 years can be used safely for lung transplantation with comparable results to lungs from younger donors in terms of postoperative mortality and mid-term survival.

Hemangiomas congénitos rápidamente involutivos: serie de 25 casos / Rapidly involuting congenital hemangiomas: twenty five case series

Los hemangiomas congénitos rápidamente involutivos son tumores vasculares muy poco frecuentes, que se caracterizan por estar completamente desarrollados al nacer (congénitos) y por tener una involución espontánea en un corto período (rápidamente involutivos). Describimos una serie de 25 casos de hemangiomas congénitos rápidamente involutivos, de los cuales 12 eran del sexo masculino y 13, femenino. Todos los pacientes eran nacidos a término, con peso adecuado para la edad gestacional. En 17, las lesiones fueron de pequeño tamaño y, en 8, de gran tamaño. Ningún paciente requirió tratamiento. En todos ellos, las lesiones mostraron una rápida involución inicial.

Rapidly involuting congenital hemangiomas are very rare vascular tumours, that are characterized for being completely developed at birth and for involuting in a short period of time after birth. We describe a case series of 25 patients with rapidly involuting congenital hemangiomas. Twelve patients were male and 13 female; they were all born at term. Lesions were small in 17 cases and big in 8. No patient needed active intervention and all lesions showed a rapid initial involution.

Registro Español de Trasplante Pulmonar: primer informe de resultados (2006-2010) / The Spanish Lung Transplant Registry: First Report of Results (2006-2010)

El Registro Español de Trasplante Pulmonar (RETP) inició su actividad en 2006, participando en él todos los equipos de trasplante pulmonar (TP) con un programa activo en España. Este informe presenta por primera vez de forma global la descripción y resultados de los pacientes trasplantados de pulmón en España entre los años 2006 y 2010. La actividad de TP ha ido en progresivo aumento, trasplantándose en este periodo 951 adultos y 31 niños. La media de edad del receptor fue de 48,2 años, siendo 41,7 años en el donante pulmonar. En el TP adulto, la causa más frecuente de trasplante fue el enfisema/EPOC, seguido de la fibrosis pulmonar idiopática, representando ambas más del 60% del total de las indicaciones. La probabilidad de supervivencia tras el TP adulto a uno y 3 años es del 72 y del 60%, respectivamente, si bien en los pacientes que sobreviven al tercer mes postrasplante estas supervivencias son del 89,7 y del 75,2%. Los factores que más claramente inciden en la supervivencia del paciente son la edad del receptor y el diagnóstico que indicó el trasplante. En los trasplantes pediátricos, la fibrosis quística es la principal causa de trasplante (68%), y la supervivencia al año es del 80, y del 70% a los 3 años. Tanto en el trasplante adulto como en el pediátrico, la causa más frecuente de fallecimiento es la infección. Estos datos confirman la consolidación del TP en España como una opción terapéutica para la enfermedad respiratoria crónica avanzada, tanto en niños como en adultos(AU)

The Spanish Lung Transplant Registry (SLTR) began its activities in 2006 with the participation of all the lung transplantation (LT) groups with active programs in Spain. This report presents for the first time an overall description and results of the patients who received lung transplants in Spain from 2006 to 2010. LT activity has grown progressively, and in this time period 951 adults and 31 children underwent lung transplantation. The mean age of the recipients was 48.2, while the mean age among the lung donors was 41.7. In adult LT, the most frequent cause for lung transplantation was emphysema/COPD, followed by idiopathic pulmonary fibrosis, both representing more than 60% the total number of indications. The probability for survival after adult LT to one and three years was 72% and 60%, respectively, although in patients who survived until the third month post-transplantation, these survival rates reached 89.7% and 75.2%. The factors that most clearly influenced patient survival were the age of the recipient and the diagnosis that indicated the transplantation. Among the pediatric transplantations, cystic fibrosis was the main cause for transplantation (68%), with a one-year survival of 80% and a three-year survival of 70%. In adult as well as pediatric transplantations, the most frequent cause of death was infection. These data confirm the consolidated situation of LT in Spain as a therapeutic option for advanced chronic respiratory disease, both in children as well as in adults(AU)

Síndrome estafilocócico de la piel escaldada. Nuestra experiencia en 10 años / Staphylococcal scalded skin syndrome (SSSS). Our 10-year experience

El síndrome estafilocócico de la piel escaldada (SEPE) es una enfermedad cutánea aguda infrecuente, causada por toxinas exfoliativas del Staphylococcus aureus. El objetivo de este estudio es describir las características epidemiológicas, clínicas y terapéuticas de los pacientes con diagnóstico de SEPE en nuestro medio.Material y métodos.Se realizó un estudio retrospectivo, descriptivo y observacional, en el que se revisaron las historias clínicas de los pacientes con diagnóstico de SEPE vistos entre mayo de 2000 y mayo de 2010, atendidos en la Sección de Dermatología Pediátrica del Hospital Ramos Mejía, y entre mayo de 2005 y mayo de 2010 en el Servicio de Dermatología del Hospital Alemán.Resultados.Se incluyó un total de 62 pacientes, cuya edad media al momento del diagnóstico fue de 22 meses. No se observó predilección por sexo ni estación del año. El 13% de los pacientes recibió corticoides sistémicos previo al diagnóstico de SEPE. Todos los pacientes excepto uno, realizaron tratamiento antibiótico luego del diagnóstico de esta entidad. El 92% recibió cefalosporinas de primera generación. El 23% de los pacientes requirió internación y el 100% evolucionó satisfactoriamente.Conclusiones.El SEPE es una entidad poco frecuente. Si bien en nuestro medio no hallamos datos epidemiológicos sobre esta entidad, los datos demográficos encontrados en este estudio difieren de los publicados en la literatura mundial. Debe sospecharse en recién nacidos y niños pequeños con eritrodermia aguda y afectación peribucal o conjuntival.

Staphylococcal scalded skin syndrome (SSSS) is a rare cutaneous disease caused by exfoliativetoxins of Staphylococcus aureus. The aim of this study is to describe the epidemiology, clinicalmanifestations and treatment of patients with the diagnosis of SSSS in our community.Methods. We conducted a retrospective, descriptive and observational study, reviewing the clinicalrecords of patients with a diagnosis of SSSS, as seen between May 2000 and May 2010 atthe Pediatric Dermatology Section of the Hospital Ramos Mejía, and between May 2005 and May2010 at the Dermatology Unit of the Hospital Alemán.Results. A total of 62 patients were included, whose average age at the time of diagnosis was22 months. No predilection for sex or season of the year was observed. Thirteen percent of thepatients received systemic steroids prior to SSSS diagnosis. All but one of the patients received antibiotictreatment after the diagnosis of this entity. First generation cephaloporins were given to92% of patients; 23% of them required hospitalization and all of them had a satisfactory outcome.Discussion. SSSS is an infrequent entity. Even though there are no epidemiological studies inour country concerning SSSS, the data we gathered differs with world-wide published literature.SSSS must be suspected in new-borns and in young children with an acute onset of erythroderma,perioral affectation and conjunctivitis.

Tratamiento del seminoma puro de testículo: estados I y II / Therapy of the pure testicular seminoma: stage I and II

Desde octubre 1976 hasta junio 1986, 185 pacientes portadores de seminoma puro de testículo han sido tratados con radioterapia. 101 pacientes etapificados en estado I recibieron irradiación infradiafragmática y 84 pacientes etapificados como estado II recibieron irradiación infra y supra diafragmática. Con seguimiento mínimo de 36 meses, la sobrevida para pacientes en estado I fue del 98%, subiendo a 99% luego de rescate, en estado II la sobrevida sin evidencia de enfermedad fue 93%, subiendo a 96% luego de rescate. Ni desarrollo de segundos tumores testiculares, compromiso escrotal, albugínea, epididímo, cordón, rete testis, carcinoma in situ, multifocalidad, diferenciación, título de beta gonadotrofinas fueron de importancia pronóstica. En pacientes en estado II sólo presencia de masa abdominal palpable fue de influencia adversa
