RESUMO

Introducción y objetivo: El objetivo de nuestro estudio fue demostrar las diferencias clínicas entre el vértigo posicional paroxístico benigno (VPPB) idiopático y secundario a síndrome vestibular agudo periférico (SVA). Método: Estudio de casos y controles, retrospectivo. La recolección de datos fue tomada de historias clínicas de nuestro hospital. Datos demográficos y clínicos de pacientes con diagnóstico de VPPB idiopático y secundario a SVA, fueron recogidos para el análisis. Además, en el grupo de los casos, se realizó una correlación entre el déficit vestibular periférico, medido a través del video head impulse test (vHIT), y el número de maniobras y tiempo hasta la resolución del VPPB. Resultados: Se incluyeron 72 pacientes, 64% mujeres. En el grupo control se incluyeron 50 pacientes con VPPB idiopático y 22 con VPPB secundario a SVA en el grupo de los casos. En el VPPB secundario, el canal semicircular posterior estuvo afectado en el 100% (OR: 1.2; IC 95% [1,088 - 1,436]). Ambos grupos mostraron una resolución del vértigo del 90% y 89%, respectivamente. El grupo de VPPB secundario tuvo 4 veces más riesgo de recurrencia (OR: 4.18; IC 95% [1.410 - 12.406]); necesitaron más maniobras (3.32 ± 2.2 vs. 1.7 ± 1.3, p = 0.004) y tiempo (61.9 días ± 73.1 vs. 12.9 días ± 9.6, p = 0.007) para la resolución del VPPB. Se encontraron correlaciones significativas entre la diferencia de ganancia media del reflejo vestíbulo-ocular (RVO) y el número de maniobras (r = 0.462, p = 0.030) y el tiempo hasta la resolución (r = 0.577, p = 0.008). Discusión: Existen diferencias clínicas entre el VPPB idiopático y secundario a SVA, principalmente en términos de canal semicircular afecto, mayor número de maniobras y tiempo en días hasta la resolución del VPPB. Además, de determinar que a mayor déficit vestibular en un paciente con VPPB secundario a SVA, necesitará un mayor número de maniobras y un tiempo prolongado hasta la resolución del VPPB. Conclusiones: ... (AU)


Introduction and Objective: The aim of our study was to demonstrate the clinical differences between idiopathic benign paroxysmal positional vertigo (BPPV) and BPPV secondary to acute peripheral vestibular syndrome (APVS). Method: Retrospective case-control study. Data collection was obtained from medical records at our hospital. Demographic and clinical data of patients diagnosed with idiopathic BPPV and BPPV secondary to APVS were collected for analysis. Additionally, in the case group, a correlation was performed between peripheral vestibular deficit, measured through the video head impulse test (vHIT), and the number of maneuvers and time until resolution of BPPV. Results: Seventy-two patients were included, with 64% being women. The control group included 50 patients with idiopathic BPPV and 22 with BPPV secondary to APVS in the case group. In secondary BPPV, the posterior semicircular canal was affected in 100% of cases (OR: 1.2; 95% CI [1.088 - 1.436]). Both groups showed a vertigo resolution rate of 90% and 89%, respectively. The secondary BPPV group had a 4-fold higher recurrence risk (OR: 4.18; 95% CI [1.410 - 12.406]); they required more maneuvers (3.32 ± 2.2 vs. 1.7 ± 1.3, p = 0.004) and more time (61.9 days ± 73.1 vs. 12.9 days ± 9.6, p = 0.007) for BPPV resolution. Significant correlations were found between the difference in mean gain of the vestibulo-ocular reflex (VOR) and the number of maneuvers (r = 0.462, p = 0.030) and the time until resolution (r = 0.577, p = 0.008). Discussion: Clinical differences exist between idiopathic BPPV and BPPV secondary to APVS, primarily in terms of the affected semicircular canal, a higher number of maneuvers, and a longer time in days until BPPV resolution. Furthermore, it was determined that a greater vestibular deficit in a patient with secondary BPPV to APVS requires a higher number of maneuvers and an extended time until BPPV resolution. Conclusions: ... (AU)

RESUMO

BACKGROUND AND OBJECTIVE: Differential diagnosis of vertigo is a diagnostic challenge in the emergency setting. In our centre we have created a vertigo protocol to distinguish the different pathologies and their management in the emergency department. Our goal is to determine the efficacy of our hospital protocol in the diagnostic and therapeutic approach to acute vestibular syndrome. PATIENTS AND METHODS: It is a retrospective descriptive observational study on patients with a diagnosis of acute vestibular syndrome in the emergency department using our unclear origin vertigo protocol. All patients underwent an examination that included the HINTS protocol and had a minimum follow-up of 6 months. The results of the clinical assessments by the specialists were compared, as well as the physical examination with the different final diagnoses classified as peripheral, central and other-origin. RESULTS: We obtained 97 patients, with a mean age of 61.46 years. The final diagnoses were 26 patients for the peripheral group (26.8%), 38 for the other-origin group (39.2%) and 33 for the central group (34%). Stroke was found in 18 of the latter group, clinical-exploratory disagreement being the most frequent reason for activation of the protocol. CONCLUSIONS: Our protocol has proven to be a useful tool to differentiate a possible acute vestibular syndrome of central origin from a peripheral one, avoiding unnecessary imaging tests. The most frequent cause of activation of the protocol was clinical-exploratory disagreement seen by the ENT doctor.

RESUMO

RESUMEN El vértigo se define como una sensación rotacional de movimiento y es uno de los principales motivos de consulta en urgencias. Aproximadamente entre el 5 y 7% de los pacientes que asisten a consulta de Medicina General han presentado esta afección en el último año. Por este motivo, es necesario tener una adecuada orientación de los casos que permita identificar su causa y diferenciar entre la patología central y periférica lo que permitirá abordar los pacientes de una manera adecuada, que permita distinguir aquellos que requieran hospitalización para estudios complementarios de los que pueden ser manejados ambulatoriamente. A continuación, revisaremos los principales síntomas clínicos, las pruebas semiológicas más utilizadas y las etiologías más relevantes para describir un abordaje sencillo de este síndrome.


SUMMARY Vertigo is defined as a sensation of rotation or imbalance and is a common complain for emergency room consultation. Approximately between 5% and 7% of patients who consulted their general physician in the last year have presented vertigo. Therefore, it is essential to have an adequate understanding of this disease to properly distinguish between the principal causes as it orients proper treatment. This article is a review of the main symptoms, frequently used clinical exams and relevant etiologies, in order to provide a simple orientation to general practitioners.

RESUMO

El paciente que consulta por mareos o vértigo es sin duda un desafío para el médico que trabaja en un servicio de urgencia. Esto se da en parte por la dificultad de los pacientes de definir el síntoma, a la amplia gama de diagnósticos diferenciales y su potencial riesgo de desenlace negativo, como en el caso del accidente cerebrovascular de fosa posterior. En esta revisión narrativa, el objetivo: es explicar el enfrentamiento inicial del paciente con mareos y vértigo, describir las pruebas y métodos diagnósticos complementarios, distinguir los diagnósticos diferenciales más frecuentes y explicar el manejo inicial. Método:se realizó una revisión bibliográfica de literatura científica sobre esta patología, basado en la propuesta de Edlow (2016), donde se enfatiza en un enfoque basado en temporalidad, factores desencadenantes y contexto del síntoma.(AU)


The patient who consults for dizziness or vertigo is undoubtedly a challenge for the emergency physician. This is partly due to the difficulty of the patients to define the symptom, the wide range of differential diagnoses and their potential risk of negative outcome, as in the case of posterior circulation stroke. In this narrative review, the objective is to explain the initial approach of the patient with dizziness and vertigo, describe the tests and complementary diagnostic methods, distinguish the most frequent differential diagnoses and explain the initial management. A bibliographic review of the scientific literature on this pathology was carried out, based on the proposal of Edlow (2016), which emphasizes an approach based on temporality, trigger factors and context of the symptom.
