Validated argentine version of the visual vertigo analogue scale.

BACKGROUND: Visual vertigo (VV), triggered by environmental or dynamic visual stimuli and repetitive visual patterns, can affect daily life activities. The Visual Vertigo Analogue Scale (VVAS) is a valid and reliable self-administered questionnaire to assess VV, which has been culturally adapted to the Argentine population but has not been validated. OBJECTIVE: To validate the Argentine version of VVAS (VVAS-A) by confirming its psychometric properties in patients with vestibular disorders. METHODS: Vestibular patients (n = 82) completed the VVAS-A and the Dizziness Handicap Inventory Argentine version (DHI-A) during their initial visit and one week later. The VVAS-A's internal consistency, test retest reliability, ceiling and floor effects, and construct validity were determined. Test-retest data (n = 71) was used to calculate reliability using the intraclass correlation coefficient (ICC 2.1). RESULTS: A ceiling effect was observed in 12 patients (14.6%). Internal consistency was acceptable (Cronbach's alpha: 0.91). The reliability was r = 0.764 [CI 95%: 0.7 -0.86]). Correlations were observed between the VVAS-A and the total DHI-A score (rho = 0.571), the DHI-A physical subscale (rho: 0.578), and DHI-A functional and emotional subscales of the DHI-A (rho: 0.537 and 0.387, respectively). CONCLUSION: The VVA-A is a valid, reliable tool to evaluate VV in patients with vestibular disorders.

The Role of the Smartphone in the Diagnosis of Vestibular Hypofunction: A Clinical Strategy for Teleconsultation during the COVID-19 Pandemic and Beyond.

Introduction Vestibular disorders (VDs) are highly prevalent in primary care. Although in general they comprise conditions that are not life-threatening, they are associated with significant functional and physical disability. However, the current coronavirus disease 2019 (COVID-19) pandemic has imposed limitations on the standard treatment of benign conditions, including VDs. In this context, other resources may aid in the diagnosis and management of patients with VDs. It is well known that teleconsultation and teletreatment are both safe and effective alternatives to manage a variety of conditions, and we maintain that VDs should be among these. Objective To develop a preliminary model of clinical guidelines for the evaluation by teleconsultation of patients with suspected diagnosis of vestibular hypofunction during the COVID-19 pandemic and beyond. Methods A bibliographic review of the diagnostic feasibility in VDs by teleconsultation was carried out in the LILACS, SciELO, MEDLINE, and PubMed databases; books and specialized websites were also consulted. The legal, regulatory, and technical issues involving digital consultations were reviewed. Results We found 6 field studies published between 1990 and 2020 in which the efficiency of teleconsultations was observed in the contexts of epidemics and environmental disorders and disadvantageous geographical conditions. After reviewing them, we proposed a strategy to examine and address vestibular complaints related to vestibular hypofunction. Conclusion The creation of a digital vestibular management algorithm for the identification, counseling, initial intervention, monitoring and targeting of people with possible vestibular hypofunction seems to be feasible, and it will provide a reasonable alternative to in-person evaluations during the COVID-19 pandemic and beyond.

Eficacia de la férula nocturna y el ultrasonido para tratar el síndrome del túnel carpiano. Estudio clínico controlado y aleatorizado / Night splinting effectiveness in carpal tunnel syndrome. A randomized controlled clinical trial

Objetivo: Comparar la eficacia de la inmovilización nocturna de la muñeca con una férula cubital en ángulo neutro junto con la aplicación de ultrasonido en pacientes con síndrome del túnel carpiano leve y moderado. Materiales y Métodos: Entre octubre de 2007 y marzo de 2010, se incluyó a pacientes >18 años con síndrome del túnel carpiano confirmado por electromiografía en un hospital de Buenos Aires. Se realizó una aleatorización estratificada, con bloques permutados aleatorios, y apareamiento por sexo y edad. Los pacientes fueron asignados al grupo experimental (GE) o al grupo de control (GC). Ambos grupos recibieron ultrasonido de 1 MHz pulsante por 15 min, 3 veces por semana, durante 6 semanas. Los pacientes del GE, además, utilizaron una férula nocturna. Se evaluaron el dolor y la parestesia con la escala analógica visual de 100 mm, la PSFS y el test de Moberg, al comenzar, a las 3 semanas y, al finalizar, a las 6 semanas, y durante el seguimiento, al mes, y a los 3 y 6 meses, con evaluador a ciego. Resultados: Se analizó a 32 pacientes del GC y a 33 del GE. Al finalizar el tratamiento, todas las variables habían mejorado en ambos grupos, con diferencia de medias estadísticamente significativa para el dolor a favor del GE a las 3 semanas de tratamiento 1,64 (IC95% 0,38-2,91; p = 0,012), pero sin diferencia clínica significativa. No se informaron efectos adversos. Conclusión: El tratamiento con una férula nocturna y ultrasonido no es superior al ultrasonido solo en pacientes con STC. Nivel de Evidencia; II

Objective: To compare the effectiveness of night wrist immobilization using an ulnar splint in neutral angle versus the use of ultrasound (US) in patients with Carpal Tunnel Syndrome (CTS). Materials and Methods: Study population included over 18 years of age that were treated for electromyography-confirmed CTS between October 2007 and March 2010 at a Buenos Aires hospital. A sex- and age-stratified randomization was performed by using randomly permuted blocks, allocating patients into the experimental group (EG) and control group (CG). Pulsed US therapy was administered for 15 minutes to all patients three times a week for six weeks at a frequency of 1 MHz. In addition, EG patients were also prescribed night splint. Pain and paresthesia were evaluated using a 100mm Visual Analogue Scale (VAS), the Patient Specific Functional Scale (PSFS), and the Moberg pickup test (MPUT) at baseline, at 3 and 6 weeks, and at 3 and 6 months after treatment institution by a blinded investigator. Results: Study population consisted of 85 cases (65 patients) that were randomly allocated to CG (n=42) or EG (n=43). Improvement of all the variables was observed at the end of treatment in both groups, with a 1.64 (95% CI: 0.38-2.91, P=0.012) statistically significant difference in means for pain in favor of the EG at 3 weeks of treatment, but without a significant clinical difference. No adverse effects were observed. Conclusion: The effectiveness of combined night splint and US therapy is not superior to the US alone treatment in CTS patients. Level of Evidence; II

Traducción y adaptación transcultural del cuestionario Visual Vertigo Analogue Scale para uso en Argentina / Translation and cross-cultural adaptation of the Visual Vertigo Analogue Scale for use in Argentina

ANTECEDENTES Y OBJETIVO: El mareo visual surge cuando la compensación de la lesión vestibular se ve interferida por una alta dependencia visual, lo que lleva a una intolerancia en situaciones de conflicto visual. El Visual Vertigo Analogue Scale (VVAS) es un cuestionario autoadministrado, válido y confiable que evalúa específicamente el mareo visual. El uso de cuestionarios en culturas y lenguas diferentes requiere que los ítems sean traducidos y adaptados culturalmente. No existe una versión del VVAS en Argentina. Los objetivos del trabajo fueron traducir y adaptar transculturalmente el VVAS al castellano para su uso en la población argentina, en pacientes con trastornos vestibulares. MATERIALES Y MÉTODOS: Se llevó a cabo desde noviembre de 2015 y enero de 2016 en el Servicio de Kinesiología de un Hospital público de la Ciudad de Buenos Aires con pacientes argentinos mayores de 18 años que presentaban algún trastorno vestibular. El proceso de traducción y adaptación transcultural se basó en la guía del proceso de adaptación transcultural de mediciones autoadministradas de Beaton et al. RESULTADOS: Se incluyeron 39 pacientes para la adaptación transcultural del VVAS. Todas las decisiones de los cambios realizados por el comité de expertos fueron para asegurar la equivalencia semántica, idiomática, experimental y conceptual entre las versiones. CONCLUSIÓN: Se ha traducido y adaptado con éxito la versión original del VVAS al castellano para ser utilizado en la población argentina con trastornos vestibulares

BACKGROUND AND OBJECTIVE: Visual dizziness occurs when high visual dependence interferes with compensation for a vestibular lesion and leads to intolerance in situations of visual conflict. The Visual Vertigo Analogue Scale (VVAS) is a self-administered, valid and reliable questionnaire that serves to assess visual dizziness. The use of questionnaires in different cultures and languages requires that they be translated and adapted to the local culture. There is no version of the VVAS in Argentina. The objectives of this study were to translate and carry out a cross-cultural adaptation of the VVAS into Spanish for use with vestibular patients in Argentina. MATERIALS AND METHODS: This study was carried out from November 2015 to January 2016 in the Kinesiology Service of a public hospital in the city of Buenos Aires. Patients were Argentines older than 18 years who suffered from a vestibular disorder. The translation and cross-cultural adaptation were based on the guide to the process of cross-cultural adaptation of self-administered measurements by Beaton et al. RESULTS: 39 patients were included in the VVAS cross-cultural adaptation process. All changes made by the committee of experts were for the purpose of ensuring the semantic, idiomatic, experimental and conceptual equivalence of the two versions. CONCLUSION: The original version of the VVAS has been translated into Spanish and adapted for use in the Argentine population with vestibular disorders

Correlation between timed up and go, usual gait speed and dizziness handicap inventory in elderly with vestibular disorders: a retrospective and analytical study.

BACKGROUND: This study was done to verify the associations between the usual gait speed (UGS), the Timed Up and Go test (TUG), and the perception of disability in elderly vestibular patients and to identify factors associated with TUG results. METHODS: This was a descriptive, analytical, and retrospective study that used data from the clinical records of vestibular patients aged 65 years or older at a rehabilitation service in Buenos Aires, Argentina. The records were examined for the following information: sex, age, type of vestibular disorder, dizziness handicap inventory (DHI) score and performance in the TUG and UGS tests before treatment. Pearson's or Spearman's correlation coefficient was used depending on the distribution of data. Age and the DHI were factored into multiple linear regression models in order to model the tests. A Receiver Operating Characteristic (ROC) curve was used to analyze the predictive power of age, the DHI total, and the UGS for the sample's TUG results. The level of significance was 5%. RESULTS: We evaluated 118 clinical records, of which 26 were excluded due to incomplete information, leaving data from 92 vestibular patients (73 females; 78.3 ± 5.8 years old). Unilateral vestibular hypofunction and Benign Paroxysmal Positional Vertigo presented the highest prevalence. The total score and the DHI domains showed a significant association with the TUG and UGS values. The age-adjusted DHI had a low predictive power for these same values. CONCLUSIONS: The total score and DHI domains have a significant association with the TUG and UGS values for elderly adults with vestibular disorders. The age-adjusted DHI has a low predictive power for TUG and UGS values.

Patient-Reported and Performance Outcomes Significantly Improved in Elderly Patients with Vestibular Impairment following Rehabilitation: A Retrospective Study.

OBJECTIVE: To describe the results of a vestibular rehabilitation (VR) program in the timed up and go (TUG), gait speed (GS), and dizziness handicap inventory (DHI) scores for elderly vestibular patients in a developing country. METHODS: Descriptive study with retrospective data collected from the clinical records of vestibular patients. The following information was recorded: sex, age, type of vestibular disorder, DHI score, and performance in TUG and GS, before and after participation in a VR program taking place from January 1 to August 30, 2017. The VR program consisted of 10 twice weekly sessions in the clinic and daily exercises at the patient's home. We used Student's t-test for paired and Wilcoxon's test according to the data distribution. The level of significance was 5%. RESULTS: Data from 57 patients (49 females; 78 ± 5.8 years old) were used. There were statistically significant differences in TUG (12.52 versus 11.56), GS (0.81 versus 0.90 m/s), DHI total handicap (46 versus 24), physical (14 versus 8), emotional (14 versus 6), and functional (18 versus 12) domains. CONCLUSION: The functional outcome measures reported, including TUG, gait speed, and DHI, reflect statistically significant improvements in elderly patients after vestibular rehabilitation; the DHI improvements are clinically relevant.

Acute Bilateral Superior Branch Vestibular Neuropathy.

The rapid onset of a bilateral vestibular hypofunction (BVH) is often attributed to vestibular ototoxicity. However, without any prior exposure to ototoxins, the idiopathic form of BVH is most common. Although sequential bilateral vestibular neuritis (VN) is described as a cause of BVH, clinical evidence for simultaneous and acute onset bilateral VN is unknown. We describe a patient with an acute onset of severe gait ataxia and oscillopsia with features compatible with acute BVH putatively due to a bilateral VN, which we serially evaluated with clinical and laboratory vestibular function testing over the course of 1 year. Initially, bilateral superior and horizontal semicircular canals and bilateral utricles were impaired, consistent with damage to both superior branches of each vestibular nerve. Hearing was spared. Only modest results were obtained following 6 months of vestibular rehabilitation. At a 1-year follow-up, only the utricular function of one side recovered. This case is the first evidence supporting an acute presentation of bilateral VN as a cause for BVH, which would not have been observed without critical assessment of each of the 10 vestibular end organs.

Unilateral Head Impulses Training in Uncompensated Vestibular Hypofunction.

The aim of this paper is to report a case of a young woman with unilateral vestibular chronic failure with a poorly compensated vestibuloocular reflex during rapid head rotation. Additionally, she developed migraine symptoms during the treatment with associated chronic dizzy sensations and blurred vision. Her report of blurred vision only improved after she completed a rehabilitation program using fast head impulse rotations towards the affected side for 5 consecutive days. We discuss why we elected this form of treatment and how this method may be useful for different patients.

Presentamos un caso en el cual planteamos el diseño de un nuevo colgajo de espesor total del carrillo, con la finalidad de reconstruir en un solo paso el labio superior, en lesiones que ocupen más del 1/3 de la longitud del labio superior. Paciente masculino de 6 años, con lesión maligna de glándulas salivales menores del tipo carcinoma mucoepidermoide, que puede ser localizado en el labio superior siendo poco frecuente. Explicamos el diseño de este colgajo el cual permite, la reconstrucción del labio superior en todo su espesor en un solo paso; incluyendo, piel, músculo y mucosa, mediante el diseño de colgajo en isla del carrillo, este mantendría su nutrición a partir de las ramas de la arteria infraorbitaria ipsilateral. Con un aceptable resultado cosmético, y mantiene una buena apertura oral, sin sacrificar los márgenes de resección, no se coloca en riesgo el control local y la curabilidad del paciente.

We present a case in which we would like to expose the design of a new cheek’s thick flap in order to reconstruct in just one step the superior lip when it has been damaged more than 1/3 of it. Patient 6 years old male with malignant lesion of the minor’s salivary glands muco-epidermoid carcinoma type, that can be found in the superior lip and is less frequent. We present a new flap that allow to reconstruct of the entire superior lip in all its extension, including skin, muscle and mucous in one step. Through the design of the island cheek flap, this would keep its nutrition for the infraorbitary ipsilateral arterial branches. This flap gives acceptable cosmetic results besides keeping a good opening of the oral cavity, without sacrificing the resection borders, in a way that local control and the curability of the patient is not put at risk.

Tumores del sistema paraganglionar / Tumors of the paragangliona system

A pesar de que los paragangliomas pueden ser observados desde la base del cráneo hasta la vejiga o a lo largo de la cadena ganglionar del simpático, sólo constituyen el 0,012 por ciento de todos los tumores diagnóticados y su hallazgo en cualquier región anatómica representa una rareza. El objetivo del presente trabajo es hacer un análisis de tres casos clínicos con diagnótico de paraganglioma vistos en nuestro hospital. De los tres pacientes, uno no fue sometido a cirugía por la localización del tumor, ameritando biopsia e inmunohistoquímica para confirmar el diagnóstico, tras el cual recibió tratamiento paliativo, falleciendo año y medio después del mismo, los otros dos pacientes tras el tratamiento quirúrgico se mantienen asintomáticos. Al diagnóstico de estos tumores como en otros, se llega inicialmente con la experiencia del clínico y su sospecha, como los estudios que permitan documentarios, tras lo cual su tratamiento como el seguimiento es fundamental
