Assessment of Saudi Physicians and Physical Therapists' Adherence to the Updated Clinical Practice Guideline for Benign Paroxysmal Positional Vertigo: A Cross-Sectional Study

Abstract Introduction Variations in clinical practice regarding the management of benign paroxysmal positional vertigo (BPPV) among clinicians have been noted in previous studies. Such variations might be related to the different adherence to clinical practice guidelines. Objective To evaluate clinicians' adherence to BPPV guidelines and investigate the variations in the adherence between different specialties and qualifications. Methods This is a cross-sectional study with a vignettes-based survey conducted between June and August, 2020. We included clinicians engaged in managing BPPV that had at least one year of clinical experience. We excluded students, and clinicians who were not involved in the management of individuals with BPPV. Participants were asked to make their management choices based on four hypothetical patient vignettes. The sample ranged from 77 participants for the first vignette to 45 participants for the last vignette. Results We included 77 clinicians in the study, with the majority being Otolaryngologists (31.2%). The respondents' mean adherence to the guideline was of 63.3%. Result showed that Otolaryngologists' adherence was higher than that of clinicians from different specialties (p = 0.006, d = 0.72). Furthermore, clinicians with a postgraduate degree were more likely to adhere than those with a bachelor's degree only (p = 0.014, d = 0.58) and participants who were aware of the guideline were more likely to adhere to it (p < 0.001, d = 1.05). Lastly, regression analysis exhibited that adherence was affected by postgraduate degree and guideline awareness. Conclusion Otolaryngologists were more likely to adhere to the guideline than other specialties. Among all specialties, higher adherence was associated with guideline awareness and postgraduate degrees.

Intratympanic Gentamicin Injection in Ménière’s Disease: Our Ten Years’ Experience and Outcomes

Objective: The aim of our study is to evaluate the effectiveness of intratympanic gentamicin injection (ITG) on vertigo control with reduced doses and its hearing effects. Materials and Method: The study was conducted at Otolaryngology Department of AORN “S.G. Moscati” between January 2005 and January 2015 on 72 patients with disabling unilateral Meniere’s disease. We use 0.2-0.3 mL of gentamicin sulfate at a concentration of 40mg/ml, injected into the affected ear through the posterior-inferior quadrant of the tympanic membrane. The procedure was carried out for three following days. Main outcome measures: vertigo control and hearing threshold changes after ITG treatment. Results: In 98.6% of the patients(n=71) the ITG produced the full remission of the vertiginous symptoms. In 91.6% of cases(n=66) a single treatment (three consequent injections) was sufficient to control vertigo, in 5.5% of cases(n=4) two treatments were necessary to control vertigo and in 1.3% of patients(n=1) three treatments were necessary to control vertigo. In no case we have had hearing loss after ITG procedure. The pre-treatment pure tone average was 48db. The post-treatment pure tone average was 49.2db. This difference was no statistical difference. Conclusion: In this study we reported high vertigo control, long follow-up and no case of significant hearing worsening. We consider the three injections in the following three days with low doses of gentamicin a safe and valid treatment for Meniere’s disease.

Humanistic Care in Clinical Diagnosis and Treatment of Elderly Benign Paroxysmal Positional Vertigo Patients / 中国医学伦理学

Benign paroxysmal positional vertigo (BPPV) is a peripheral vestibular disease with the highest incidence rate, and the elderly are the high incidence population. Particle repositioning maneuver, simple and practicable, and has good clinical effects, is recognized as the preferred treatment method for BPPV. However, the elderly patients have a higher prevalence rate, often suffer from multiple chronic diseases, and their various bodily functions have entered a declining stage, with poor response to treatment and a tendency to recur. Based on these, medical staff should continuously improve their professional abilities, and pay attention to and implement some comprehensive and multi-dimensional humanistic care measures from physiological to psychological aspects such as verbal encouragement, behavioral support, and spiritual integration during the diagnosis and treatment process, to improve the quality of life of elderly BPPV patients, reduce medical disputes, and save medical resources.

ObjectiveTo compare the short-term effectiveness of the three different manipulations for atlantoaxial joint disorders and their effects on surface electromyography of sternocleidomastoid muscle. MethodsNinty patients with atlantoaxial joint disorders were randomly divided into the tendon relaxing manipulation group， the tendon relaxing plus rehabilitation manipulation group， and the conventional manipulation group， with 30 cases in each group， and each group of patients received the corresponding manipulation treatment for 2 weeks. The changes of visual analogue score （VAS） of occipital neck pain， evaluation scale for cervical vertigo （ESCV）， and averaged electromyography （AEMG） of surface electromyography of bilateral sternocleidomastoid muscles before and after the treatment were observed， and the clinical effectiveness and safety of the patients were compared among groups. ResultsThe VAS scores of patients in each group decreased， and the ESCV scores increased after treatment （P＜0.01）， and the tendon relaxing manipulation group and the tendon relaxing plus rehabilitation manipulation group were significantly better than the conventional manipulation group （P＜0.01）. The AEMG of the bilateral sternocleidomastoid muscles of the three groups increased after treatment （P＜0.01）； when compared among the three groups， the AEMG of the bilateral sternocleidomastoid muscles of the tendon relaxing plus rehabilitation manipulation group was higher than that of the tendon relaxing manipulation group， and the tendon relaxing manipulation group was higher than that of the conventional manipulation group （P＜0.05 or P＜0.01）. The cure and markedly effective rates of the tendon relaxing manipulation group， the tendon relaxing plus rehabilitation manipulation group， and the conventional manipulation group were 56.67%， 86.67%， and 36.67% respectively， showing statistically difference （K=10.21， P＜0.01）. ConclusionThe tendon relaxing manipulation and tendon relaxing plus rehabilitation manipulation can effectively improve the symptoms of vertigo， headache， and neck pain for patients with atlantoaxial joint disorders， and can improve the contraction function of sternocleidomastoid muscle， whose effectiveness are better than that of conventional manipulation.

ZHANG Zhiyuan's Experience in Using Baizhu （Atractylodes macrocephala） in Clinical Practice / 中医杂志

Professor Zhang Zhiyuan， a master of Chinese medicine， made good use of Baizhu （Atractylis macrocephala （Koidz.））. Except for defecation in clinical practice， he usually prescribed processed Baizhu after stir-frying with soil. Baizhu is good at excreting water and removing dampness， so applied it in the formula series with Fuling （Poria cocos） and Guizhi （Cassia Twig） or self-made decoction for diarrhea. High-dose Baizhu could be used for edema by treating obstructive syndrome with tonics， so Baizhu were added in self-made Shugan Qushui Decoction （疏肝祛水汤） or modified Lizhong Decoction （理中汤） for liver cirrhosis ascites. It was emphasized that Baizhu could eliminate phlegm， so added it in modified Zexei Decoction （泽泻汤） for excess syndrome of vertigo. It was also acknow-ledged that Baizhu could strengthen the spleen and stomach， and was suitable for deficiency or excess syndrome of abdominal distension， so applied it in Burun Decoction （补润汤） for abdominal distension with deficiency-excess in complexity， and applied it in Zhizhu Decoction （枳术汤） or self-made Tiaozhong Decoction （调中汤） for deficient abdominal distention.

Outcome Indicators in Randomized Controlled Trials on Traditional Chinese Medicine Treatment of Vertigo / 中国实验方剂学杂志

ObjectiveThis study analyzed the outcome indicators in randomized controlled trials （RCTs） on traditional Chinese medicine （TCM） treatment of vertigo， aiming to provide a reference for clinical trial protocol design and the establishment of core indicator sets for vertigo treatment. MethodCNKI， Wanfang， VIP， SinoMed， PubMed， Embase， and Web of Science were searched for the RCTs on TCM treatment of vertigo， and data extraction was conducted. ResultA total of 375 RCTs involving 33 593 patients were included， from which 482 outcome indicators were extracted， with a frequency of 2 715 and an average of seven outcome indicators used for each RCT. In addition， there were some differences in outcome indicators reported by different study groups. According to the functional properties， the reported outcome indicators were classified into nine domains： clinical symptoms and signs， TCM symptom efficacy， physical and chemical examinations， quality of life， mental health， safety events， patients’ satisfaction degree， long-term prognosis， and economic evaluation. The outcome indicators with higher frequency were clinical total effective rate， total TCM symptom score， occurrence of adverse reactions， dizziness handicap inventory （DHI） score， average flow velocity of the basilar artery， incidence of adverse reactions， average flow velocity of the left vertebral artery， average flow velocity of the right vertebral artery， plasma viscosity， and vertigo score. ConclusionThe outcome indicators reported by RCTs of TCM treatment of vertigo mainly have two problems： lack of unified standards and norms and insufficient attention to outcome indicators that can reflect the characteristics of TCM. The construction of the core indicator set for TCM treatment of vertigo should fully highlight the characteristic advantages of TCM and unify the standards and norms for the outcome indicators on this basis， so as to improve the quality of clinical research and the value of secondary research.

Analysis of continuous polysomnography in children with recurrent vertigo / 临床耳鼻咽喉头颈外科杂志

Objective:To explore the relationship between sleep status and the disease in children with recurrent vertigo（RVC） by analyzing the objective sleep condition of children with recurrent vertigo. Methods:According to the diagnostic criteria of RVC, 50 children with RVC and 20 normal controls without RVC were selected. According to the vertigo questionnaire score, the RVC group was divided into mild, moderate and severe groups according to severity. Continuous polysomnography（PSG） was performed for all participants, and SPSS 25.0 statistical software was used to analyze the monitoring results. Results:①There were significant differences in sleep time of each period, total sleep time and sleep efficiency between RVC group and control group（P<0.05）, but there was no significant difference in sleep latency（P>0.05）. The specific manifestations were that the proportion of sleep time in N1 and N2 phases increased, the proportion of sleep time in N3 and REM phases decreased, the total sleep time and sleep efficiency decreased in RVC group. ②The abnormal rate of sleep apnea hypopnea index, that is, the proportion of AHI≥5 times/h and the abnormal rate of lowest blood oxygen saturation in RVC group were higher than those in normal control group. There was significant difference between the two groups（P<0.05）. ③There were significant differences in the proportion of AHI≥5 times/h and lowest SpO2 among mild group, moderate group and severe group（P<0.05）. ④There was no significant correlation between the degree of vertigo and the abnormal rate of AHI in children with RVC, but there was a negative correlation between the degree of vertigo and the abnormal rate of lowest SpO2 in children with RVC. Conclusion:Children with RVC are often accompanied by sleep disorders, clinicians should pay attention to both the symptoms of vertigo and sleep condition in children. Polysomnography is non-invasive and operable, providing a new idea to the auxiliary examination of RVC in children. It is of certain clinical significance for the comprehensive treatment of children with RVC to actively improve vertigo symptoms and pay attention to improving sleep quality.

Achados neurológicos e vestibulares em três casos de Esclerose Múltipla / Neurological and vestibular findings in three cases of Multiple Sclerosis

RESUMO A Esclerose Múltipla (EM) é uma doença autoimune crônica e inflamatória que afeta o sistema nervoso central (SNC). A disfunção do equilíbrio corporal também é um sintoma comum e pode estar relacionada às lesões neurológicas decorrentes desta doença. O objetivo deste estudo foi caracterizar os achados neurológicos e vestibulares de três casos clínicos com diagnóstico de EM. Dados sobre a avaliação neurológica e do exame de ressonância magnética de crânio foram coletados dos prontuários. Os pacientes responderam a uma entrevista inicial e foram submetidos à avaliação clínica do equilíbrio corporal e ao Video Head Impulse Test (vHIT). Observou-se presença de sintomas vestibulares e alterações em pelo menos uma das provas clínicas do equilíbrio corporal e função cerebelar. No vHIT, obteve-se alterações em testes oculomotores, como presença de nistagmo semi-espontâneo e em parâmetros do teste sacádico, e ganho reduzido em um ou mais canais verticais. Foram verificadas lesões, na ressonância magnética de crânio, em áreas centrais que processam as informações vestibulares, como cerebelo e tronco encefálico. A associação destes achados sugere a presença de disfunção vestibular central, compatível com as lesões detectadas nos exames de imagem.

ABSTRACT Multiple sclerosis (MS) is a chronic and inflammatory autoimmune disease that affects the central nervous system (CNS). Dysfunction of body balance is also a common symptom and may be related to neurological injuries resulting from this disease. The aim of this study was to characterize the neurological and vestibular findings of three clinical cases diagnosed with MS. Data on the neurological evaluation and the magnetic resonance imaging of the skull were collected from the medical records. The patients responded to an initial interview and underwent clinical assessment of body balance and Video Head Impulse Test (vHIT). Vestibular symptoms and alterations were observed in at least one of the clinical tests of body balance and cerebellar function. In vHIT, changes were obtained in oculomotor tests, such as the presence of semi-spontaneous nystagmus and in parameters of the saccade test, and reduced gain in one or more vertical channels. Lesions were found on MRI of the skull in central areas that process vestibular information, such as the cerebellum and brainstem. The association of these findings suggests the presence of central vestibular dysfunction, compatible with the lesions detected in imaging exams.

Terapia de rehabilitación vestibular en alteración mixta (central y periférica). Reporte de un caso / Vestibular rehabilitation therapy in mixed (central and peripheral) disorder. A case report

La terapia de rehabilitación vestibular es el tratamiento con mayor evidencia en la recuperación para la mayoría de los trastornos de equilibrio. En los casos que presentan una alteración estable del procesamiento central del equilibrio, o mixta, es decir, acompañada de una alteración a nivel del sistema nervioso periférico, la terapia de rehabilitación vestibular no se excluye como tratamiento. No obstante, los progresos suelen ser limitados y requieren de una mayor cantidad de sesiones. En este trabajo analizaremos un caso mixto, un paciente con síndrome de núcleo fastigial y el vértigo posicional paroxístico benigno (VPPB), desde la pesquisa y evaluación hasta el tratamiento y alta, en el Hospital Clínico Universidad de Chile.

Vestibular rehabilitation therapy is the treatment with the greatest evidence of recovery for most balance disorders. In the cases that have a loss of central balance processing, or mixed, that is, stable accompanied by a disorder of the peripheral nervous system the vestibular rehabilitation therapy is not excluded as a treatment; however, progress is usually limited and requires a greater number of sessions. In this work we will analyse a mixed case, a patient with nucleus fastigial syndrome and a benign paroxysmal positional vertigo, from the investigation and evaluation to the treatment and discharge, at the Hospital Clínico Universidad de Chile.

Controle postural na doença de Menière / Postural control in Menière's disease

RESUMO Objetivo Avaliar o controle postural na doença de Menière. Métodos 34 pacientes com doença de Menière definida (grupo experimental) e 34 indivíduos hígidos (grupo controle), homogêneos quanto à idade e ao gênero, foram submetidos à posturografia do Tetrax Interactive Balance System (Tetrax IBS TM) em oito condições sensoriais. Índice de estabilidade, índice de distribuição de peso, índice de sincronização da oscilação postural direita/esquerda e dedos/calcanhar, frequência de oscilação postural e índice de risco de queda foram analisados. Resultados O índice de estabilidade foi maior no grupo experimental, com diferença significativa entre os grupos, em todas as condições sensoriais testadas. O risco de queda foi maior no grupo experimental do que no grupo controle. A oscilação postural foi maior no grupo experimental em todas as faixas de frequência, com diferença significativa em algumas delas. Não houve diferença significativa entre os grupos nos índices de distribuição de peso e de sincronização, nas oito condições sensoriais avaliadas. Conclusão Pacientes com doença de Menière apresentam comprometimento do controle postural, caracterizado por alterações do índice de estabilidade, em frequências de oscilação postural e no índice de risco de queda.

ABSTRACT Purpose To evaluate postural control in Menière's disease. Methods 34 patients with Menière's disease (experimental group) and 34 healthy individuals (control group) were submitted to Tetrax Interactive Balance System posturography under eight sensory conditions. Stability, weight distribution, synchronization, risk of falling and postural oscillation frequency were analyzed. Results Stability index was higher in the experimental group with significant difference between the groups in all sensory conditions. Risk of falling was higher in the experimental group than in the control. Postural oscillation was higher in the experimental group in all frequency ranges, with significant difference in some of them. There was no significant difference between the groups in the weight distribution and synchronization indexes. Conclusion In this study, Menière's disease patients presented impaired postural control, characterized by postural instability and oscillation and risk of falling.
