Empleo de patrones de imagen en la identificación de metástasis cervical mediante tomografía computarizada en tumores de cabeza y cuello
Objetivo Evaluar la seguridad diagnostica que proporcionan las imagenes de tomografia computarizada (TC) para identificar la extension regional de tumores de cabeza y cuello (CC). Pacientes y metodo Se efectuo TC a 86 pacientes diagnosticados de neoplasia de faringe y/o laringe que despues fueron intervenidos, con un total de 142 vaciamientos ganglionares. En el estudio de imagen se consideraron los siguientes parametros radiologicos para sospechar afeccion ganglionar: tamano de la adenopatia > 10-11 mm, margenes mal definidos, necrosis central, forma esferica, realce capsular y agrupacion de tres o mas adenopatias. Resultados El 48,5 % de los vaciamientos resultaron N+. La sensibilidad y l…
Taponamiento nasal en la epistaxis posterior. Comparación de dos métodos
Resumen Objetivo Evaluar la tolerancia y eficacia de 2 sistemas de taponamiento nasal para epistaxis posteriores refractarias. Pacientes y metodos Estudio comparativo longitudinal y prospectivo de 5 anos en pacientes que acudieron a Urgencias por epistaxis y precisaron taponamiento posterior. Se consideraron 2 grupos: uno atendido con un sistema de hinchado neumatico bicameral (n = 105); otro en el que se efectuo oclusion posterior con gasa accediendo por boca y refuerzo anterior (n = 47). La tolerancia se midio mediante escala analogica de intensidad dolorosa durante la colocacion y mantenimiento del tapon, asi como por necesidad de analgesia. La eficacia se valoro por indices de resangrad…
[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].
Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…
Nasal packing in posterior epistaxis. Comparison of two methods
Objective: To evaluate tolerance and efficiency of two nasal blocking systems for posterior refractory epistaxis. Patients and methods: A five year comparative and longitudinal prospective study was developed in patients with epistaxis who attended our Emergency Unit and who required posterior nasal packing. Two groups were considered: one group was treated with a bi-chamber pneumatic inflation system (n=105). In the other one, posterior occlusion was carried out with gauze, accessing through the mouth and using nasal reinforcement (n=47). The tolerance was measured by means of an analogue scale of pain intensity during the placement and maintenance of the packing, as well as for the need o…
Consideraciones sobre la otitis externa aguda para un tratamiento optimizado
Resumen Introduccion y objetivo Evaluar el tratamiento idoneo de la otitis externa aguda difusa mediante un nuevo sistema de estadiaje basado en hallazgos clinicos y otoscopia. Metodos Seguimiento de los casos de otitis diagnosticados en nuestro centro durante los ultimos 21 meses (n=1.026). Recuento del numero de pacientes que acudieron a una segunda visita urgente o programada. Estadiaje de la otitis externa si la obstruccion del conducto auditivo externo presentaba obstruccion inferior al 25% (tipo I, n=174), entre el 25–75% (tipo II, n=277), mayor del 75% (tipo III, n=359), u obstruccion completa con edema organizado (tipo iv , n=216). Resultados La aspiracion y el mechado del conducto …
Considerations on acute otitis externa for its optimized treatment
Abstract Introduction and objectives To evaluate the optimal treatment for diffuse acute otitis externa (DAOE) by means of a new staging system based on clinical and otoscopic findings. Methods Monitoring of otitis cases diagnosed at our centre over the last 21 months (n = 1026), taking into account those who returned for a second visit, either via the emergency room or with a prior appointment. Staging of otitis externa by degree of obstruction of the external auditory canal (EAC): under 25% (type I, n = 174); between 25% and 75% (type II, n = 277); over 75% (type III, n = 359); total obstruction due to organized oedema (type IV, n = 216). Results In most cases at an advanced stage, the ca…
