RESUMO
Introducción: La patología otorrinolaringológica (ORL) presenta alta incidencia en atención primaria, alcanzando hasta 49% de las consultas, sin embargo, la pandemia por SARS-CoV-2 repercutió de manera transversal en los servicios sanitarios, pudiendo haber influido en el perfil de consulta, por lo que se requiere un análisis para la elaboración de estrategias que permitan asegurar la atención sanitaria ante eventos de esta magnitud. Objetivo: Analizar el perfil de consulta libre por patología ORL ambulatoria en un centro médico privado en La Serena durante los años 2019 y 2020. Material y Método: Estudio analítico de corte transversal sobre consultas ambulatorias durante los años 2019 y 2020 realizadas en un centro privado de atención abierta en La Serena. Se estimaron frecuencias en números absolutos y proporciones, estimación de promedios y medianas. Resultados: Durante 2019 hubo un total de 11.932 consultas y en 2020 hubo 9.576. Se observó un predominio de sexo femenino en las consultas de 51% en ambos años. La mediana en 2019 fue de 35 años y en 2020 de 39 años. En 2020 las patologías con mayor consulta fueron nariz (44%), oído (37%) y faringolaringe (14%). Existió un aumento significativo en la consulta por patología cocleovestibular durante 2020. Conclusión: En 2020 hubo una disminución del 19,7% de las consultas dado, probablemente, a las restricciones de movilidad y aforos. Existió un aumento significativo en la proporción de consultas por patologías cocleovestibulares, como vértigo periférico, hipoacusia súbita y tinnitus, atribuido probablemente al estrés emocional generado por la pandemia.
Introduction: Otolaryngological (ENT) pathology presents high incidence in primary care reaching up to 49% of morbidity consultations, however, the pandemic by SARS-CoV-2 had a transversal impact on health services, and may have influenced the consultation profile, so an analysis is required for the development of strategies to ensure health care in the face of events of this magnitude. Aim: To analyze the profile of spontaneous consultation for outpatient ENT pathology in a medical center in La Serena city during 2019 and 2020. Material and Methods: Cross-sectional analytical study of outpatient consultations during the years 2019 and 2020 performed in a private open care center in the commune of La Serena. Frequencies were estimated in absolute numbers and proportions; averages and medians were estimated. Results: During 2019 there were a total of 11,932 consultations and in 2020 there were 9,576. There was a predominance of female sex in the consultations of 51%. The median in 2019 was 35 years and in 2020 it was 39 years. In 2020, the pathologies with the highest number of consultations were nose (44%), ear (37%) and laryngopharynx (14%). There was an increase in consultation for cochleovestibular pathology during 2020. Conclusion: In 2020 there was a 19.7% of consultation decrease probably due to mobility and capacity restrictions. There was a significant increase in the proportion of consultations for cochleovestibular pathologies such as peripheral vertigo, hearing loss and tinnitus, probably attributed to the emotional stress generated by the pandemic.

Resumen Introducción: El cáncer de esófago (CE) constituye la sexta causa de muerte por cáncer en el mundo. La disección endoscópica submucosa (DES) es una técnica que permite la resección en bloque de lesiones del tubo digestivo. Tiene rol curativo en pacientes seleccionados y potenciales ventajas sobre la esofagectomía. Objetivo: Describir los resultados perioperatorios y oncológicos de la DES como tratamiento del CE en nuestro centro. Materiales y Método: Estudio retrospectivo de pacientes sometidos a DES por CE entre los años 2010-2020. Resultados: Diez pacientes fueron tratados con DES por CE entre los años 2010 y 2020. El 80% eran hombres y la edad promedio fue de 72 años (63-84). La resección en bloque fue lograda en todos los casos y no se presentó morbimortalidad perioperatoria. Todas las disecciones fueron R0 y el 90% cumplió con estándares de curación. El seguimiento promedio fue de 38 meses (3,5-123). La sobrevida global fue de 90%. La sobrevida específica por cáncer y libre de recurrencia fue de 100%. Discusión: La morbimortalidad asociada a la esofagectomía es alta. La DES sería una alternativa más segura, que permite lograr un R0 y eventualmente la curación en pacientes seleccionados con CE limitado a la mucosa o submucosa. Conclusión: La presente constituye la primera serie reportada de pacientes con cáncer esofágico sometidos a DES en nuestro país. Muestra excelentes resultados oncológicos y seguridad del procedimiento, comparables a las grandes series descritas en la literatura internacional.
Introduction: Esophageal cancer is the sixth leading cause of death by cancer worldwide. Endoscopic submucosal dissection (ESD) is a technique that allows en bloc resection of early lesions of the digestive tract. It has curative potential in selected patients and potential benefits over esophagectomy for the treatment of esophageal cancer (EC). Aim: To report the results of ESD for EC in a high-volume center in Chile. Materials and Method: Retrospective descriptive study of patients who underwent ESD for EC at our center. Results: A total of 10 patients were treated with ESD for EC between 2010 and 2020. Eighty percent were male patients, the average age was 72 years (63-84). En bloc resection was achieved in all cases and there were no complications or mortality. All of the dissections were classified as R0 and 90% met curative standards. The mean follow-up was 38 months (3.5-123). Overall survival was 90%. Cancer-specific survival was 100% and recurrence-free survival was 100%. Discussion: The rate of morbidity and mortality of esophagectomy is high. ESD would be a safer technique, which allows R0 resections and eventually curation in selected patients with EC limited to the mucosa or submucosa. Conclusion: This is the first report of ESD for the treatment of EC in our country, it shows excellent oncologic results and safety of the procedure, comparable to those reported in the larger series published to date.

Congenital pulmonary airway malformations (CPAM) are rare and occur due to a failure in lung embryological development. They are classified according to their pathological characteristics and their anatomical origin. They can occur from the antenatal period to adulthood, can be associated with hydrops fetalis, respiratory distress, recurrent infections, or in an otherwise asymptomatic patient. In this article we carry out a scope review of the literature to answer frequent questions of the clinical teams in charge of patients with CPAM, such as the antenatal approach, the different types of surgeries and the management of asymptomatic patients. Although the indication for surgery is clear in symptomatic patients, little is known about its natural history of this condition, including the possibility of spontaneous resolution and the development of complications or neoplasm. So, the treatment of asymptomatic patients continues to be controversial. Therapeutic decisions must be made by multidisciplinary teams with the informed participation of parents and patients. In our opinion, considering the excellent results of minimally invasive surgery, its low incidence of complications, and practically zero mortality when performed by experienced groups, it seems reasonable to consider elective resection of a MCVAP in asymptomatic patients.
Las malformaciones congénitas de la vía aérea pulmonar (MCVAP) son infrecuentes y ocurren debido a una falla en el desarrollo embriológico pulmonar. Se clasifican de acuerdo con sus características patológicas y a su origen anatómico. Se pueden presentar desde el periodo antenatal hasta la adultez, asociarse a cuadros de hidrops fetal, distrés respiratorio, infecciones recurrentes, o como un hallazgo en pacientes asintomáticos. En este artículo realizamos una revisión bibliográfica exploratoria para responder dudas frecuentes de los equipos clínicos a cargo de pacientes con MCVAP, como el enfrentamiento antenatal, los distintos tipos de cirugía y su abordaje, y el manejo de pacientes asintomáticos. Si bien la indicación de cirugía es clara en pacientes sintomáticos, poco se conoce acerca de su historia natural, incluyendo la posibilidad de resolverse de forma espontánea, de complicarse o de evolucionar hacia el desarrollo de una neoplasia, por lo que el tratamiento de pacientes asintomáticos continúa siendo controversial. Las decisiones terapéuticas deben ser tomadas por equipos multidisciplinarios con la participación informada de los padres y de los pacientes. En nuestra opinión, considerando los excelentes resultados de la cirugía mínimamente invasiva, su baja incidencia de complicaciones y prácticamente nula mortalidad, al ser realizada por grupos con experiencia, nos parece razonable plantear la resección electiva de una MCVAP en un paciente asintomático.

BACKGROUND: Carbapenemase-producing Enterobacteriaceae (CPE) has become a significant problem in terms of public health and clinical outcome. OBJECTIVE: To assess the epidemiology, treatment and mortality in patients with infection due to CPE. MATERIAL AND METHODS: A retrospective analysis of 163 patients with CPE infection was carried out in a university hospital from July 2013 to October 2015. RESULTS: A total of 163 patients were included over the study period. Klebsiella pneumoniae was isolated in 95.1% of cases, and most of carbapenemases belonged to the OXA-48 group (93.0%). Acquisition was nosocomial in 124 cases (77.0%), healthcare-associated in 30 (18.6%), and 7 cases (4.3%) were community-acquired. The most frequent infections identified in this study were urinary tract (48.4%) and respiratory (19.5%) infections. Approximately half of the patients received antibiotic monotherapy. The 30-day mortality rate was 23.3%. Multivariate analysis revealed that the presence of septic shock at diagnosis (OR 4.2; IC 95% 1.5-11) was independently associated with an increase in death during the first month, unable to identify association with inappropriate antibiotic treatment. DISCUSSION: Further studies are needed to clarify whether antibiotic treatment of EPC infections should be combined or if monotherapy might be sufficient in mild infections.

Resumen Introducción: Las enterobacterias productoras de carbapenemasas (EPC) suponen un reto para la salud pública y la práctica clínica. Objetivo: Analizar la epidemiología, el tratamiento y la mortalidad en pacientes infectados por EPC. Material y Métodos: Análisis retrospectivo de 163 pacientes infectados por EPC en un hospital universitario desde julio de 2013 a octubre de 2015. Resultados: Klebsiella pneumoniae fue aislada en 95,1% de los casos, y la mayoría de las carbapenemasas pertenecían al grupo OXA-48 (93%). La adquisición fue nosocomial en 124 casos (77%), asociada a cuidados sanitarios en 30 (18,6%), y 7 (4,3%) fueron de adquisición comunitaria. Las infecciones más frecuentes fueron las del tracto urinario (48,4%) y las respiratorias (19,5%). Aproximadamente, la mitad de los pacientes recibieron monoterapia antimicrobiana. La tasa de mortalidad a los 30 días fue de 23,3%. El análisis multivariante identificó que la presencia de shock séptico al diagnóstico (OR 4,2; IC 95% 1,5-11) estaba asociada de manera independiente con mayor mortalidad en el primer mes, sin lograr identificar asociación con el tratamiento antimicrobiano inapropiado. Discusión: Son necesarios más estudios para aclarar si el tratamiento antimicrobiano de las infecciones por EPC debe ser combinado o si podría ser suficiente la monoterapia en infecciones leves.

INTRODUCTION: Pleuropulmonary blastema (PPB) is the most common primary malignancy of the lungs in childhood. It occurs more frequently in children between one and four years of age, and respiratory symptoms are a common manifestation. Three types have been defined (type I, II and III), which are related to survival and prognosis. OBJECTIVE: To report the first case of a patient with a PPB who presented with a chest wall deformity. CASE REPORT: One year old male patient who had a chest wall deformity at ten months of age. Imaging revealed a giant cyst in the right hemithorax. He did not develop respiratory symptoms until hospital admission. A right upper lobectomy was perfor med and the biopsy confirmed a type I pleuropulmonary blastoma. He was considered successfully treated with complete surgical excision and routine follow-up with thoracic imaging is conducted. CONCLUSIONS: PPB is a very rare cancer that needs to be considered in the differential diagnosis of cystic lung diseases in children. The recognition of this lesion as a malignant tumour rather than a developmental cystic malformation is vital so the child can receive complete excision and appropriate follow-up care.

INTRODUCCIÓN: El blastema pleuropulmonar (BPP) es la neoplasia primaria maligna más común de los pulmones en la infancia. Se presenta con mayor frecuencia en niños entre 1 y 4 años, con sínto mas respiratorios. Han sido definidos tres tipos por histopatología (tipo I, II y III), relacionados con sobrevida y pronóstico. OBJETIVO: Reportar el primer caso de un paciente con un BPP que se presentó como una deformación de la pared torácica. CASO CLÍNICO: Paciente de un año de vida que se presentó con una deformidad de la pared torácica a los 10 meses de edad. El estudio imagenológico reveló una gran masa quística en el hemitórax derecho. No desarrolló sintomatología respiratoria hasta el ingreso hospitalario. Se realizó una lobectomía superior derecha y la biopsia confirmó un BPP tipo I. Se trató con resección quirúrgica y realización periódica de imágenes torácicas como seguimiento. CONCLUSIONES: Se reporta el caso de un BPP que se manifestó con deformidad torácica, forma de presentación no descrita previamente en la literatura. El BPP es un cáncer poco frecuente que debe ser considerado en el diagnóstico diferencial de lesiones quísticas pulmonares, sobre todo en la edad pediátrica. Reconocerlo como un tumor maligno en vez de una anomalía del desarrollo, es determinante para que el paciente sea sometido a resección quirúrgica, terapia adyuvante y seguimiento apropiado.

Resumen Introducción: La acalasia es el trastorno motor primario más frecuente del esófago. El estándar de tratamiento actual es la miotomía de Heller laparoscópica. En los últimos años, el desarrollo de técnicas endoscópicas avanzadas ha permitido el posicionamiento de la técnica POEM (del inglés: per-oral endoscopic myotomy) como una nueva alternativa terapéutica con resultados promisorios. Objetivo: Presentar nuestra experiencia clínica, con descripción de la técnica utilizada, resultados perioperatorios y seguimiento a corto plazo en el desarrollo de esta alternativa terapéutica. Materiales y métodos: Se realizó un análisis retrospectivo de datos obtenidos en forma prospectiva de 15 pacientes intervenidos mediante POEM en 3 hospitales docentes asociados. Se recopilaron variables demográficas preoperatorias, detalle del intraoperatorio y registro de morbimortalidad operatoria. Se realizó un seguimiento clínico dirigido registrando el puntaje de Eckardt y la presencia de síntomas de reflujo gastroesofágico. Resultados: Entre agosto de 2015 y noviembre de 2016 se realizaron 15 POEM. Seis de estos pacientes eran mujeres, y la edad promedio fue de 49 años. El tiempo operatorio promedio fue de 110 min; no hubo morbimortalidad operatoria. La estadía hospitalaria promedio fue de 2,8 días. El seguimiento fue de entre 1 y 15 meses. El puntaje de Eckardt promedio en el preoperatorio y en el postoperatorio fue de 10,5 y 0,4 puntos, respectivamente. Tres pacientes presentaban síntomas de reflujo gastroesofágico al momento del seguimiento. Conclusión: Los resultados obtenidos en nuestra serie apoyan la efectividad y seguridad del POEM a corto plazo. Se requiere de un seguimiento mayor para determinar el rol definitivo de esta técnica.
Abstract Introduction: Achalasia is the most common primary motor disorder of the esophagus. The current standard of treatment is laparoscopic Heller's myotomy. Recently the development of advanced endoscopic techniques has allowed the positioning of the POEM (per-oral endoscopic myotomy) technique as a new therapeutic alternative with promising results. Objective: To present our clinical experience in POEM, with description of the technique used, peri-operative results and short-term follow-up in the development of this therapeutic alternative. Materials and methods: We performed a retrospective analysis of data obtained prospectively from 15 patients undergoing POEM in three clinical centers in our country. Preoperative demographic variables, intraoperative detail, and operative morbidity and mortality were collected. Clinical follow-up was performed with controls recording Eckardt score and presence of gastroesophageal reflux symptoms. Results: Between August 2015 and November 2016, 15 POEM were performed, six of these patients were women, average age was 49 years. The average operative time was 110 min, we did not have any perioperative morbimortality. Hospital stay was 2.8 days. Follow-up was between 1 and 15 months, Eckardt's preoperative and postoperative score was on average 10.5 and 0.4 points, respectively. Three patients had gastroesophageal reflux symptoms at the time of follow-up. Conclusion: Our results support the effectiveness and security of POEM in short-term follow up. Further monitoring is required to determine the definitive role of this technique.

BACKGROUND: The clinical usefulness of blood cultures in the management of patients hospitalized with community-acquired pneumonia (CAP) is controversial. AIM: To determine clinical predictors of bacteremia in a cohort of adult patients hospitalized for community-acquired pneumonia. MATERIAL AND METHODS: A prospective cohort of 605 immunocompetent adult patients aged 16 to 101 years (54% male) hospitalized for CAP was studied. The clinical and laboratory variables measured at admission were associated with the risk of bacteremia by univariate and multivariate analysis using logistic regression models. RESULTS: Seventy seven percent of patients had comorbidities, median hospital stay was 9 days, 7.6% died in hospital and 10.7% at 30 days. The yield of the blood cultures was 12.6% (S. pneumoniae in 69 patients, H. influenzae in 3, Gram negative bacteria in three and S. aureus in one). These results modified the initial antimicrobial treatment in one case (0.2%). In a multivariate analysis, clinical and laboratory variables associated with increased risk of bacteremia were low diastolic blood pressure (Odds ratio (OR): 1.85, 95% confidence intervals (CI) 1.02 to 3.36, p < 0.05), leukocytosis e" 15,000/mm³ (OR: 2.18, 95% CI 1.22 to 3.88, p < 0.009), serum urea nitrogen e" 30 mg/dL (OR: 2.23, 95% CI 1.22 to 4.05, p < 0.009) and serum C-reactive protein e" 30 mg/dL (OR: 2.20, 95% CI 1.22 to 3.97, p < 0.01). Antimicrobial use before hospital admission significantly decreased the blood culture yield (OR: 0.14, 95% CI 0.04 to 0.46, p < 0.002). CONCLUSIONS: Blood cultures do not contribute significantly to the initial management of patients hospitalized for community-acquired pneumonia. The main clinical predictors of bacteremia were antibiotic use, hypotension, renal dysfunction and systemic inflammation.
