A Comparison Study of Nutritional Assessment, Diet and Physical Activity Habits, Lifestyle and Socio-Demographic Characteristics in Individuals with and without Dizziness/Vertigo.

Dizziness and vertigo are growing health problems and have become responsible for increases in health expenditures. In this context, a case-control study has been conducted by nutritional assessment, including dietary and physical activity habits, lifestyle, and socio-demographic characteristics in adults with (patient group) and without (control group) dizziness or vertigo, and the outcomes were compared between these groups. The patient (n = 150) and control (n = 150) groups included 300 participants. The 24-h Dietary Recall and the food frequency questionnaire (FFQ-21) were conducted in order to gain detailed information about foods and beverages consumed by the participants. Additionally, a questionnaire was completed, assessing general socio-demographic (age, gender, etc.) and lifestyle (smoking, alcohol consumption, and obesity) characteristics, anthropometric measurements, and dietary and physical activity habits. The results revealed that there is an association between dizziness/vertigo and female gender and increasing age. Smoking status and alcohol consumption did not differ between the groups, whereas differences in body mass index and obesity were significantly higher in the patient group (65%; n = 98) than the control group (46%; n = 69) (p = 0.001). Skipping meals "everyday" was significantly high (p = 0.044), and lunch was the most skipped meal in the patient group. The three most preferred cooking methods were oven baking, boiling, and frying for both groups. Daily water intake in the patient group was lower than in the control group (p = 0.026). Dietary intake for carotene and vitamin K were significantly lower in the patient group than the control group, but the opposite was true for vitamin D intake (p < 0.05). Daily consumption of bread and dairy products were highest in the patient group (p < 0.05). The physical activity rate was 35% (n = 53) in the control group and 28% (n = 42) in the patient group. Regular walking was the most preferred activity in both groups (p = 0.037). Active monitoring of individual diet and hydration along with supporting professional counseling are advisable. In addition, a healthy lifestyle including weight control and regular physical activity can be helpful to reduce symptoms of dizziness/vertigo.

Assessment of vestibulo-ocular reflex with video head impulse test in epilepsy patients undergoing carbamazepine monotherapy.

OBJECTIVE: Carbamazepine may cause clinical effects such as dizziness and nystagmus. This may depend on the duration of use. The aim of this study is to measure the effect of carbamazepine monotherapy on the vestibular system electrophysiologically by using Video Head Impulse Test (VHIT) and to compare the numerical and objective data obtained between the groups. PATIENTS AND METHODS: In this study, in which 55 people (110 ears) participated, Video Head Impulse Test (VHIT) was performed to evaluate the vestibulo-ocular reflex (VOR) in the epilepsy patients and a healthy control group consisting of healthy individuals. In addition, patients were analyzed in two groups to demonstrate the long-term effects of carbamazepine (<10 years and >10 years). Right/left lateral, anterior, posterior semi-circular canals (SCCs) VOR gains, lateral, left anterior right posterior, and right anterior right posterior gain asymmetries were measured between groups. RESULTS: Lateral SCCs VOR gains were 0.878±0.057 and 0.921±0.045 between the patient and healthy control groups, respectively (p=0.024). A decrease in the right and left lateral SCCs VOR gains (0.885±0.062 and 0.868±0.063) was detected in the patients (p=0.011 and p=0.001). Those using carbamazepine for >10 years had a decrease in lateral SSCs VOR gains (0.843±0.055) compared to those using the drug for <10 years (0.902±0.046) (p=0.008). CONCLUSIONS: A relative reduction in lateral (right/left) SCCs VOR gains was found in epilepsy patients using carbamazepine and in the group of patients using this drug for a long time (>10 years).

Sick sinus syndrome diagnosed after a sinus arrest during treatment for zygomatic fracture: a case report.

BACKGROUND: Intraoperative sinus arrest is rarely seen during zygomatic fracture treatment. The patient was diagnosed with sick sinus syndrome based on repeated postoperative sinus arrest, which could have resulted in death if diagnosed late, making this case very significant to report. CASE PRESENTATION: Sick sinus syndrome is an arrhythmia associated with reduced automaticity of the sinoatrial node or impaired sinoatrial node conduction. We report the case of a 67-year-old man diagnosed with the syndrome after a sinus arrest that occurred during a zygomatic fracture treatment. The patient had cheek pain and mouth opening disorder, dizziness after fainting and sustaining a facial injury. Preoperative examination determined that the syncope was due to drug-induced arrhythmia, and surgery was authorized after drug withdrawal. During the operation, sinus arrest was observed due to trigeminal vagal reflex, and heart rate was restarted by stopping the operation and chest compressions. After the surgery, the patient showed symptoms of dizziness and palpitations, and sinus arrest following atrial fibrillation and supraventricular tachycardia, which was diagnosed as sick sinus syndrome, and a pacemaker was implanted. Currently, 8 years have passed since the surgery, and there are no symptoms of mouth opening disorder, dizziness, or palpitations. CONCLUSIONS: In the case of maxillofacial injuries due to syncope, cardiogenic syncope is a possibility, and repeated syncope is a risk for death due to delayed diagnosis. There are no reports of maxillofacial trauma leading to a diagnosis of sick sinus syndrome. The purpose of this case report is to disseminate the importance of diagnosing the cause of syncope as well as injury treatment.

Cervical Spine Instability Screening Tool Thai Version: Assessment of Convergent Validity and Rater Reliability.

Neck pain, dizziness, difficulty supporting the head for an extended period, and impaired movement are all symptoms of cervical spine instability, which may produce cervical spondylolisthesis in patients who have more severe symptoms. To avoid problems and consequences, early detection of cervical spine instability is required. A previous study created a Thai-language version of a cervical spine instability screening tool, named the CSI-TH, and evaluated its content validity. However, other characteristics of the CSI-TH still needed to be evaluated. The objective of the current study was to assess the rater reliability and convergent validity of the CSI-TH. A total of 160 participants with nonspecific chronic neck pain were included in the study. The Neck Disability Index Thai version (NDI-TH), the Visual Analog Scale Thai version (VAS-TH), and the Modified STarT Back Screening Tool Thai version (mSBST-TH) were used to evaluate the convergent validity of the CSI-TH. To determine inter- and intra-rater reliabilities, novice and experienced physical therapists were involved. The results showed that rater reliabilities were excellent: the intra-rater reliability was 0.992 (95% CI = 0.989 ± 0.994), and the inter-rater reliability was 0.987 (95% CI = 0.983 ± 0.991). The convergent validities of the VAS-TH, NDI-TH, and mSBST-TH when compared with the CSI-TH were 0.5446, 0.5545, and 0.5136, respectively (p < 0.01). The CSI-TH was developed for use by physical therapists and is reliable. It can be used by physical therapists, whether they are experienced or novices, and has an acceptable correlation to other neck-related questionnaires. The CSI-TH is concise, suitable for clinical use, and lower-priced when compared to the gold standard in diagnosis for patients with cervical spine instability.

Effects of Epley procedure on BPPV patients: a systematic review of randomized controlled trails.

OBJECTIVE: The purpose of the study is to assess the effects of the Epley maneuver on patients with BPPV. MATERIALS AND METHODS: International libraries such as MEDLINE, Cochrane, Web of Science, and PubMed, among others, were used to evaluate evidence on the effectiveness of Epley's procedure on BPPV published between January 2000 and December 2022. For accessing the articles, several search phrases, such as "Epley Maneuver", "BPPV", "Vertigo", "Vestibular Rehabilitation", and "Physical Therapy" were utilized. A total of 69 papers were retrieved and assessed for inclusion and exclusion criteria based on the article title, abstract, and inclusion and exclusion criteria. Following that, the quality of the chosen studies was assessed using the PEDro scale. RESULTS: Only seven studies fulfilled the eligibility criterion and were evaluated out of a potential 69 records found. A total of 413 BPPV-screened individuals were examined. The findings of the studies chosen for review revealed that Epley's technique had a considerable, significantly positive influence on the alleviation of symptoms for BPPV patients, including nystagmus, dizziness, and quality of life. The patients described feeling better after performing the Epley maneuver for a prolonged time. CONCLUSIONS: The research ended with data confirming the benefit of the Epley maneuver in relieving symptoms in BPPV patients.

Smartphone-Assisted Medical Care for Vestibular Dysfunction as a Telehealth Strategy for Digital Therapy Beyond COVID-19: Scoping Review.

BACKGROUND: Dizziness and vertigo can be caused by various factors, such as peripheral vestibular and central disorders. Although consultations with specialists are advisable when necessary, patients with severe vertigo symptoms may have limited mobility, which may interfere with hospital visits. The spread of COVID-19 has further limited the number of hospital visits for patients with dizziness; therefore, a method of medical care that enables more accurate treatment under time and geographical constraints is needed. Telemedicine has become widespread, owing to the popularity of smartphone and tablet devices in recent years, and the use of devices and systems has made it possible to provide efficient medical care. However, no previous scoping review has mapped existing studies on telemedicine for vertigo and dizziness, and no recommendations have been made regarding which devices and systems should be used for specific diseases. OBJECTIVE: The aim of this review was to map and assess previous studies on the use of information communications technology, smartphones, and apps for treating patients with vertigo and discuss the added value of introducing telemedicine to improve the quality of medical care and create an environment that builds security and trust among patients. METHODS: A scoping review was conducted with the methodological framework of Arksey and O'Malley and in accordance with the of the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews) guidelines. The PubMed, MEDLINE, and Cochrane Library databases were searched to retrieve previous reports on smartphone-assisted telemedicine treatment for vertigo published between January 2000 and May 2023. Two authors independently assessed eligibility and extracted data. RESULTS: This review included 20 papers that reported devices or systems for telemedicine for vestibular dysfunction. Among studies that reported the use of a device or app, 2 were related to anamnesis and subjective symptoms, 12 were related to objective examination, 7 were related to remote diagnosis, and 7 were related to treatment and rehabilitation. CONCLUSIONS: With the advancement of technology, the use of telemedicine in patients with dizziness may be feasible. In the future, it will be necessary to consider how telemedicine can be used in dizziness treatment and develop an effective treatment system combining in-person medical care and the effective use of devices for the management of severe vertigo and related diseases. The smooth introduction of telemedicine in vertigo treatment is expected to improve the quality of treatment, increase opportunities for patients to receive medical care, and reduce time and travel costs, leading to a sense of security and trust among patients.

Abnormal uterine bleeding: an insidious presentation.

An adolescent was referred to the emergency department due to abnormal uterine haemorrhages in the previous 2 months, associated with dizziness in the last month. At observation, she was haemodynamically stable, with good clinical impression, but evident mucocutaneous pallor. Full blood count confirmed a severe anaemia (haemoglobin 47 g/L). She received red blood cell transfusion (10 mL/kg) and started oral oestradiol. She was discharged, with oral oestradiol and oral iron supplementation. Two weeks later, she started treatment with oestradiol and progestin. The patient had a good recovery, without new similar episodes.

Intratympanic dexamethasone in Manières disease and symptom control.

BACKGROUND: Manières disease (MD) is a chronic inner ear disease characterized by recurrent vertigo and fluctuation in auditory symptoms. Vertigo spells have a sudden onset and are difficult for patients to handle. Therefore, treating a patient with MD is still a challenge for clinicians. AIMS: This study aims to analyse the short-term effects of intratympanic dexamethasone (ITD) on the various symptoms of unilateral MD. MATERIALS AND METHODS: The study comprised 27 patients with unilateral MD and severe vertigo who failed medication therapy. Treatment was with ITD as an alternative to destructive therapy. Treatment is evaluated after four months. RESULTS: Significant improvements were measured with Dizziness Handicap Inventory (DHI), Tinnitus Handicap Inventory (THI), frequency of vertigo attacks longer than 20 min, Functional Level Scale (FLS), and tinnitus sensation measured by the Analog Visual Scale (AVS). Patients with severe symptoms grading with DHI and THI experienced the most improvement. Patients have achieved substantial vertigo control in 73%. CONCLUSION: ITD application shows improvement in controlling vertigo and tinnitus in patients under exacerbation in MD. SIGNIFICANCE: It is a promising non-destructive addition to the 'stepwise treatment concept' in MD and can be used as a first-line treatment in vertigo control.

Development and validation of the dizziness fear-avoidance behaviours and beliefs inventory for patients with vestibular disorders.

The purpose of this study is to present the development and analysis of the factorial structure and psychometric properties of a new self-administered questionnaire (Dizziness Fear-Avoidance Behaviours and Beliefs Inventory (D-FABBI)) designed to measure fear-avoidance behaviors and cognitions related to dizziness disability. A mixed-method design combining a qualitative study with an observational and cross-sectional study was employed to develop (content validity) and psychometrically validate (construct validity, reliability, and convergent/discriminant validity) a new instrument. A total of 198 patients with vestibular disorders (acute vestibular syndrome (AVS), 23.2%; chronic vestibular syndrome (CVS), 35.4%; and episodic vestibular syndrome (EVS) 41.4%) were recruited. Sociodemographic characteristics, the Dizziness Handicap Inventory (DHI) and the Hospital Anxiety and Depression Scale (HADS) and D-FABBI were evaluated. The final version of the D-FABBI consists of 17 items distributed across two subscales: activities of daily living fear-avoidance and movement fear-avoidance. The D-FABBI showed high internal consistency (Cronbach α = 0.932; 95% CI [0.91-0.94]) and so did the subscales (Cronbach α > 0.8). The exploratory structural equation model and confirmatory factor analysis provided better fit results, with a comparative fit index and root mean square error of approximation values of 0.907 to 0.081. No floor or ceiling effects were identified. There was a positive, significant, and moderate-strong magnitude correlation with the total DHI (r = 0.62) and low-moderate with respect to the HADS depression (r = 0.35) and HADS anxiety subscales (r = 0.26). The patients with CVS had a higher D-FABBI score than those with AVS or EVS. The D-FABBI appears to be a valid and reliable instrument for measuring the fear-avoidance behaviors and cognition related to dizziness disability of patients with vestibular disorders.

The German Revised version of the Niigata PPPD Questionnaire (NPQ-R): Development with patient interviews and an expert Delphi consensus.

BACKGROUND: Persistent postural-perceptual dizziness (PPPD) is a functional disorder of the nervous system and currently one of the most common types of chronic dizziness. Currently existing questionnaires do not fully assess patients' specific symptoms of PPPD. The Japanese Niigata PPPD Questionnaire (NPQ) was recently developed following consensus-based diagnosis criteria. The aim of this study was to translate it into German, evaluate its content with the help of experts and patients and, if necessary, revise the original version to allow for a comprehensive assessment of patients' PPPD-related symptoms. METHODS: A 3-round expert Delphi survey and semi-structured patient interviews were conducted. 28 experts from Switzerland, Germany and Austria working in hospitals or outpatient centres were asked to complete a first questionnaire on various aspects of PPPD, on the translated, original NPQ and their own related experiences (Round one), a second questionnaire with statements regarding PPPD they could agree or disagree with using a 6-point Likert-scale (Round two), and a third survey to finally reach a consensus on statements to be integrated into the NPQ. In addition, eleven patients (mean age of 64.6±12.6 years; 6 females) were selected according to the criteria for the diagnosis of PPPD proposed by the Bárány Society and participated in a semi-structured interview asking for their opinion on the content of the original NPQ. All collected data were analysed using a descriptive evaluation and a qualitative content analysis based on verbatim transcripts. RESULTS: Seven new items were added to the NPQ based on expert and patient comments and ratings. Its revised version (NPQ-R) comprises 19 items divided into five subscales using a 7-point Likert-scale with two additional subscales relating to associated symptoms and symptom behaviour in PPPD. The new maximal score is 114 points compared to 72 for the NPQ. CONCLUSION: The NPQ-R is the first patient-reported outcome measurement for patients with PPPD in German. It should help to provide a comprehensive assessment of the intensity of PPPD in affected patients.

Longitudinal Patient Outcomes in Chronic Dizziness: A Scoping Review.

BACKGROUND: Chronic dizziness can cause significant functional impairment. Outcome measures used in this patient population have not been examined systematically. Consequently, providers lack consensus on the ideal outcome measures to assess the impact of their interventions. OBJECTIVE AND METHODS: We conducted a scoping review to summarize existing literature on outcomes in chronic dizziness (with a minimum of 6 mo of patient follow-up). Among other details, we extracted and analyzed patient demographics, medical condition(s), and the specific outcome measures of each study. RESULTS: Of 19,426 articles meeting the original search terms, 416 met final exclusion after title/abstract and full-text review. Most studies focused on Ménière's disease (75%) and recurrent benign paroxysmal positional vertigo (21%). The most common outcome measures were hearing (62%) and number of attacks by American Academy of Otolaryngology-Head & Neck Surgery criteria (60%). A minority (35%) looked formally at quality-of-life metrics (Dizziness Handicap Index or other). CONCLUSIONS: Ménière's disease and benign paroxysmal positional vertigo are overrepresented in literature on outcome assessment in chronic dizziness. Objective clinical measures are used more frequently than quality-of-life metrics. Future work is needed to identify the optimal outcome measures that reflect new knowledge about the most common causes of chronic dizziness (including persistent postural-perceptual dizziness and vestibular migraine) and consider what is most important to patients.

Type, dose, and outcomes of physical therapy interventions for unilateral peripheral vestibular hypofunction: protocol for a systematic review.

BACKGROUND: Unilateral peripheral vestibular hypofunction can result in symptoms of dizziness, gaze and gait instability, and impaired navigation and spatial orientation. These impairments and activity limitations may negatively impact an individual's quality of life, ability to perform activities of daily living, drive, and work. There is strong evidence supporting vestibular physical therapy for reducing symptoms, improving gaze and postural stability, and improving function in individuals with vestibular hypofunction. However, there is great variability in clinical practice with regard to the type of interventions and only weak evidence to guide optimal exercise dosage. It is important to identify the most appropriate interventions and exercise dosage to optimize and accelerate recovery of function and to decrease distress. The objective of this systematic review is to determine which interventions and which doses are most effective in decreasing dizziness or vertigo, improving postural control, and improving quality of life in adults with unilateral peripheral vestibular hypofunction. METHODS: The literature will be systematically searched using the following online databases: PubMed/MEDLINE, EMBASE, Web of Science (Science and Social Science Citation Index), Cumulative Index for Nursing and Allied Health Literature (CINAHL), and The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials [CENTRAL], Cochrane Methodology Register). The review will include randomized controlled trials (RCTs), including cluster RCTs, to assess the beneficial effects of the interventions. Assessment of methodological quality and risk of bias will be performed by two independent, blinded reviewers using the PEDro scale and Cochrane Risk of Bias version 2, respectively. The primary outcome measure will be change in self-perceived handicap related to dizziness from baseline to the end of the study, measured using the Dizziness Handicap Inventory. Other relevant outcome measures will include self-reported change in symptoms (to include severity, frequency, and duration) such as verbal or visual analog scales for dizziness. Tertiary outcome measures will include questionnaires related to disability and/or quality of life. DISCUSSION: This systematic review will identify, evaluate, and integrate the evidence on the effectiveness of physical therapy interventions for unilateral peripheral vestibular hypofunction in an adult population. We anticipate our findings may inform individualized treatment and future research. Clinical recommendations generated from this systematic review may inform vestibular physical therapy treatment of individuals with unilateral peripheral vestibular hypofunction. TRIAL REGISTRATION: In accordance with the guidelines, our systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 06 August 2021 (registration number CRD42021266163 ). In the event of protocol amendments, the date of each amendment will be accompanied by a description of the change and the rationale.

Vertigo and dizziness in children: When to consider a neurological cause.

Vertigo is common in childhood and adolescence. Although children and adults share common causes of vertigo, epidemiology changes with aging. For instance, ischemic stroke is less frequent in childhood, whereas audiovestibular disorders, such as vestibular neuritis and the migraine equivalent, are the leading causes of vertigo. However, even if severe causes of vertigo are rare, clinicians must not miss them. In this review, we discuss the neurological causes of central vertigo in children. The diagnostic approaches reviewed here are focused on the search for signs of severity, such as an abrupt onset, infectious context, or intracranial hypertension, which may subsequently require brain imaging.

Reabilitação vestibular: sua efetividade após a alta / Vestibular rehabilitation: Its effectiveness after discharge / Rehabilitación vestibular: su efectividad después del alta

ntrodução: A reabilitação vestibular é um tratamento para tontura crônica que utiliza exercícios personalizados visando restaurar o controle postural e reduzir a tontura. Pouco se discute na literatura sobre os benefícios em longo prazo desta intervenção. Objetivos: Descrever o perfil dos pacientes atendidos no Ambulatório de Reabilitação Vestibular e verificar a melhora do equilíbrio corporal após a alta fonoaudiológica. Métodos: Foram colhidas informações acerca dos dados sociodemográficos, diagnóstico, tratamento anterior e queixas existentes. As informações foram obtidas por contato telefônico e acesso aos prontuários. Os dados foram analisados estatisticamente utilizando nível de significância de 5%. Resultados: Participaram 26 indivíduos, sendo 21 (80,8%) do gênero feminino, com média de idade de 67 anos. A queixa principal foi tontura não rotatória. O resultado do teste vestibular mais comum foi hipofunção vestibular unilateral. Dentre os entrevistados, 25 (96,2%) relataram melhora dos sintomas com o tratamento, com redução da pontuação obtida no Dizziness Handicap Inventory. Sete participantes (26,9%) permaneceram assintomáticos desde o término da reabilitação. Aqueles que relataram ainda sentirem tontura, descreveram que esta possui menor intensidade que no período anterior à intervenção.Conclusão: Houve prevalência de indivíduos do gênero feminino, idosos, com ensino fundamental incompleto, sem diagnóstico otoneurológico estabelecido, com queixa de tontura não rotatória e resultado do teste vestibular de hipofunção vestibular unilateral.A reabilitação vestibular foi eficaz para redução dos sintomas apresentados. A exposição sucessiva aos exercícios após o tratamento auxilia na manutenção do equilíbrio. Contudo, a adesão à realização dos exercícios após a alta ainda é baixa. (AU)

Introduction: Vestibular rehabilitation is a treatment for chronic dizziness that uses personalized exercises aimed at restoring postural control and reducing dizziness. There is little discussion in the literature about the long-term benefits of this intervention. Objectives: To describe the profile of patients seen at the Vestibular Rehabilitation Outpatient Clinic and verify body balance improvement after speech-language-hearing therapy discharge. Methods: Sociodemographic data, diagnosis, previous treatment, and existing complaints were collected. The information was obtained via phone calls and medical records. The data were statistically analyzed using a significance level of 5%. Results: 26 individuals participated, of whom 21 (80.8%) were female, with a mean age of 67 years. The main complaint was non-rotational dizziness. The most common vestibular test result was unilateral vestibular hypofunction. Among the interviewees, 25 (96.2%) reported improved symptoms after the treatment, with reduced Dizziness Handicap Inventory scores. Seven participants (26.9%) remained asymptomatic since the end of rehabilitation. Those who still reported dizziness described it as less intense than before the intervention. Conclusion: There was a prevalence of females, older adults with incomplete middle school, no established otoneurological diagnosis, complaint of non-rotational dizziness, and vestibular test results of unilateral vestibular hypofunction. Vestibular rehabilitation effectively reduced the symptoms. Successive exposure to exercises after treatment helps maintain balance. However, adherence to exercise after discharge is still low. (AU)

Conclusión: Hubo una prevalencia de individuos del género femenino, ancianos, con educación primaria incompleta, sin un diagnóstico otoneurológico establecido, con queja de vértigo no rotatorio y un resultado del examen vestibular de hipofunción vestibular unilateral. La rehabilitación vestibular fue efectiva para reducir los síntomas presentados. La exposición sucesiva a los ejercicios después del tratamiento ayuda a mantener el equilibrio. Sin embargo, la adherencia a la realización de los ejercicios después del alta sigue siendo baja. (AU)

Impact of anti-CGRP monoclonal antibodies on migraine attack accompanying symptoms: A real-world evidence study.

BACKGROUND: Clinical trials on anti-calcitonin gene-related peptide monoclonal antibodies poorly investigated their impact on migraine accompanying symptoms. OBJECTIVE: To evaluate the impact of basal accompanying symptoms on anti-CGRP monoclonal antibodies treatment response and their evolution after six months of treatment in migraine patients. METHODS: Patients with migraine diagnosis seen in the Headache Clinic and treated with erenumab, galcanezumab or fremanezumab were prospectively recruited. They completed a daily eDiary which provided data on headache frequency and the following accompanying symptoms of each day: photophobia, phonophobia, nausea, dizziness, and aura. Patients were classified as responders or non-responders based on 50% or greater reduction in headache days per month at month 6 (≥50% response rate). Accompanying symptoms ratios based on headache days per month were assessed per patient at baseline and after three and six months. Comparisons for basal characteristics, basal accompanying symptoms ratios and their evolution after six months between responders and non-responders were performed. RESULTS: One hundred and fifty-eight patients were included, 44% (69/158) showed ≥50% response rate after six months. A significant reduction in headache days per month in both groups was found at month 6 (-9.4 days/month in ≥50% response rate group; p < 0.001, -2.2 days/month in <50% response rate group; p = 0.004). Additionally, significant decreases in photophobia (-19.5%, p < 0.001), phonophobia (-12.1%, p = 0.010) and aura ratios (-25.1%, p = 0.008) were found in ≥50% response rate group. No statistically significant reductions were found in nausea and dizziness in any group since their reduction was correlated with the decrease in headache days per month. Higher photophobia ratios at baseline were predictive of an increased response between months 3 and 6 (Incidence Risk Ratio = 0.928, p = 0.040). CONCLUSIONS: The days per month with photophobia, phonophobia and aura decreased at a higher rate than headache days per month after six months in the ≥50% response group. Higher photophobia ratios were associated with higher response rates between three and six months. It could indicate an involvement of peripheral CGRP in photophobia as well as a central modulation of migraine through these treatments which mainly act on the periphery.

[THE HIDDEN VESTIBULAR FEATURES OF MACHADO JOSEPH DISEASE (SPINOCEREBELLAR ATAXIA 3)].

INTRODUCTION: Machado-Joseph disease (MJD) is an inherited neurodegenerative disease with progressive cerebellar ataxia manifested through lack of coordination and balance. MJD patients also present significant Vestibulo-Ocular Reflex (VOR) deficit but their whole vestibular features have not been previously evaluated. We aimed to evaluate whether MJD patients have vestibular features fitting the diagnostic criteria of Bilateral Vestibulopathy established by the International Society for Neuro-otology. METHODS: Sixteen MJD patients and 21 healthy controls underwent a detailed clinical neuro-otological examination including a quantitative evaluation of the VOR gain using the video Head Impulse Test (vHIT). Vestibular-related symptoms were evaluated by the Dizziness Handicap Inventory (DHI), the Activities-specific Balance Confidence Scale (ABC), the Vertigo Visual Scale (VVS). In addition, anxiety that is frequently present in vestibular disorders, was evaluated by the Beck Anxiety Inventory (BAI). RESULTS: MJD patients had significantly reduced horizontal VOR gain with significantly higher scores in all vestibular-related symptoms questionnaires. These symptoms scores were like those reported in studies evaluating patients with bilateral peripheral vestibular loss. CONCLUSIONS: Beyond the cerebellar deficits, MJD patients have vestibular signs and symptoms fitting the diagnostic criteria of Bilateral Vestibulopathy established by the International Society for Neuro-otology. These findings are of relevance not only for the diagnosis and evaluation of progressive cerebellar diseases but also for the possible beneficial effect of vestibular rehabilitation techniques on dizziness, balance and the emotional, physiological and functional aspects of MJD.

[EVALUATION OF THE DIZZY PATIENT - FROM THE VESTIBULAR IMPAIRMENT TO THE PATIENT'S FUNCTIONAL ABILITY].

INTRODUCTION: The vestibular system - the sixth sense - allows humans to preserve balance, stable vision, and body orientation in space. This system performs a continuous integration of the activity of the vestibular end-organ in the inner ear, the sense of sight, and the proprioceptive sense. Damage to the components of the vestibular system causes dizziness, imbalance, and poor orientation in space. Following vestibular injury, central compensation mechanisms are recruited to reduce the symptoms and improve the functional ability of the dizzy patient. Dizziness is a subjective complaint. Yet, the development that has taken place in the field of vestibular function testing allows accurate diagnosis, targeted treatment, and disability assessment of the dizzy patient. The dizzy patient must be examined meticulously, taking into account all the levels on which the vestibular impairment can affect (physiological, behavioral, and functional). Meaning, clinical and laboratory evaluation of the vestibular function together with functional testing of the patient. In this article, the authors present the range of existing innovative tests of the vestibular system. Vestibular tests are accepted in advanced vestibular laboratories in Israel and around the world, and enable assimilation in vestibular clinics and medical committees in Israel.

Unilateral non-lesional temporal lobe epilepsy presenting as isolated ictal vertigo: a case report.

Temporal lobe epilepsy is the most common focal epilepsy syndrome and has a broad spectrum of presentations. Nevertheless, isolated vestibular symptoms without other symptoms typical of temporal lobe seizures are relatively rare. Here, we report one female patient who suffered from chronic refractory vertigo and had inappropriate pharmacotherapy for several years. Eventually, epileptic vertigo and dizziness (ictal vertigo) were accurately diagnosed by detailed history taking and serial examinations assisted by sphenoid electroencephalography. Awareness of this unique syndrome is important in the diagnosis of patients with epileptic vertigo and dizziness.

Evaluation of Commercially Available Fall Detection Systems.

Falls are a serious problem in the hospital setting and home environments. However, this problem does not only affect the elderly, but also people who have had surgery, have disabling problems, have associated diagnoses (such as poor eyesight, confusion, etc.) or are dizzy or have walking aids. The aim of research was to find, compare and implement fall detectors especially for the hospital environment. This paper summarizes possible fall detectors. Various technological solutions were selected for testing, including wearable technologies as well as contactless technologies based on PIR detectors and mmWave technologies. The selected fall detectors were tested in living laboratory of HEALTHLab.vsb.cz and then in Hospital AGEL Trinec - Podlesí. The best result of the testing was the use of two Vayyar Home Care devices in one room, thus achieving a detection accuracy of 92.50 % and a sensitivity of 92.50 %.

A Dorsolateral Medullary Infarct Presenting with Isolated Dysphagia.

Posterior circulation cerebrovascular events comprise approximately 20% of ischemic events in the brain. Symptoms range from dizziness to profound ataxia altering gait. The majority of cases have some spectrum of dizziness. In this case report, we discuss a dorsolateral medullary stroke which atypically presented with dysphagia and without dizziness or ataxia. Although initial computed topography scans did not show large vessel occlusion or acute infarct, magnetic resonance imaging showed a right dorsolateral medullary infarct. Treatment is similar to other ischemic cerebrovascular accidents, including aspirin and high-intensity statin therapy, as well as thrombolysis if indicated. Pharyngeal dysfunction places a patient at higher risk for aspiration and pneumonia.
