BACKGROUND: Persistent Postural Perceptual Dizziness (PPPD) is a newly defined condition which was added to the International Classification of Vestibular Disorders in 2017. Little is known about its impact on patients. OBJECTIVE: The goal of this study was to analyze the symptomology, epidemiology and impact of PPPD on patients. METHODS: A retrospective chart review was done to identify patients who attended the Multidisciplinary Dizziness Clinic (MDC) and were diagnosed with PPPD. Responses to demographic questions, health-related quality of life surveys and several well-validated questionnaires commonly used to assess dizziness severity were analyzed. RESULTS: One hundred patients were diagnosed with PPPD between March 2017 and January 2019, of which 80%(80/100) were females. The average Dizziness Handicap Index score was 60.3±19.0. Responses to the Patient Health Questionnaire classified 53 patients (53/99;53.5%) as moderately to severely depressed. Sixty-four patients (64/100;64.0%) were minimally or mildly anxious according to the Generalized Anxiety Disorder scale. The average Vertigo Symptom Scale score was 24.1/60. The average Situational Vertigo Questionnaire score was 2.00. Forty-nine (49/100;49.0%) patients had migraine symptoms according to the Migraine Screen Questionnaire. CONCLUSIONS: In conclusion, patients with PPPD display important handicap and an elevated risk of depression, anxiety and migraines.
Au Canada, dans les milieux cliniques, les questions liées à la toxicomanie restent d’actualité (1). De ce fait, il serait important de s’assurer d’avoir sur le terrain des professionnels de la santé compétents capable de prendre en charge des patients aux prises avec ce trouble. Mais, force est de constater que sur le terrain, les professionnels de la santé, notamment les médecins, ne sont pas assez formés à offrir un service de qualité à ces patients (2). Pour répondre à cette situation, les facultés de médecine ajustent actuellement au besoin leur curriculum afin d’augmenter les connaissances des étudiants sur le sujet. En effet, il existe en ce moment une volonté de la part des Facultés de Médecine d'augmenter de façon significative l'offre de formation en médecine de la toxicomanie notamment aux études sous-graduées.Dans ce contexte, l'Association des Facultés de Médecine du Canada (AFMC) a développé un module extensif qui est proposé aux Facultés. Au cours de la refonte du curriculum qui a lieu en ce moment à l'Université d’Ottawa, il y a une volonté d'implanter ce module. L'objectif de cet revue de portée est d'investiguer les stratégies pédagogiques qui ont été employées dans les Facultés de Médecine à travers le monde pour enseigner la Médecine de la Toxicomanie aux études sous-graduées. Nous utiliserons le modèle PRISMA-ScR pour guider la rédaction de la revue de la portée.
