Quality of primary care and quality of life from the point of view of older patients with dizziness. Results oft the cohort study MobilE-TRA

The treatment of elderly patients with dizziness/vertigo/balance disorders (VDB) can be challenging for their general practitioner. Patient-centered care with a focus on self-management support could be a possible approach. Primary objective of this study was to investigate the correlations between quality of primary care and health-related quality of life (HRQOL) from the patient's perspective. Data had been collected in the area of Munich and in the area of Dresden between 2017 and 2019. Questionnaires of n = 157 elderly patients from primary care practices in Munich and Dresden were evaluated. Multiple linear regression was used to analyse quality of care, physical activity, depression, and their correlations with HRQOL. In this cohort of patients aged 65 to 94 no significant correlation between quality of care and HRQOL could be detected. Depression correlated negatively with HRQOL, whereas physical activity showed a positive correlation with HRQOL. Physical activity can be beneficial for elderly dizzy patients' HRQOL. Additionally, a potential depression should be taken into account when treating patients with dizziness to improve their HRQOL. The results can be well transferred to elderly patients with VDB. Analysing more patients however, could increase the significance of the results.

High Riding Jugular Bulb

Introduction: High jugular bulb (HJB) is usually discovered incidentally; however, it may interfere with inner ear structures such as vestibular aqueduct (VA), facial nerve, and the posterior semicircular canal (PSCC). Objective: The aim is to investigate the incidence of HJB in benign paroxysmal positional vertigo patients with PSCC involvement (PSCC-BPPV). Materials and Methods: The study group included 53 consecutive, PSCC-BPPV patients, diagnosed in our clinic. Following the diagnosis, their high resolution computed temporal bone tomography were performed. The control group consisted of 90 patients, who attended to our clinic for various complaints, and to whom high resolution computed tomography of the temporal bone was conducted. Results: The incidence of HJB in the study group was 41.5% (n = 22). The incidence of ipsilateral HJB in this group was 28.3% (n = 15). The incidence of HJB in the control group was 11.1% (n = 10) (P < 0.001). The closest distance between HJB and PSCC canal in the control and study groups was 1.61 ± 0.74 mm and 1.17 ± 0.37 mm, respectively (P = 0.098). Conclusion: The HJB is significantly more frequent in PSCC-BPPV patients. Furthermore, the rate of incidence of HJB in the ipsilateral ears of these patients is significantly higher. Venous hypertension or the turbulence may cause strong pulsations, which influence the detachment of the otoconia into the PSCC.

Effect of vitamin D supplementation on benign paroxysmal positional vertigo recurrence: A meta-analysis.

Benign paroxysmal positional vertigo is characterized by recurrence, which exposes patients to repeated vertigo attacks. Vitamin D deficiency has been found to be a risk factor in benign paroxysmal positional vertigo, although effect of its elimination on recurrence reduction remains unknown. To determine the effect of vitamin D supplementation in preventing recurrence of benign paroxysmal positional vertigo patients with vitamin D deficiency using a meta-analysis study. We searched and retrieved relevant articles from several databases, then used the Cochrane evaluation system or Methodological Index for Non-Randomized Studies (MINORS) to assess the quality of studies. We adopted risk-ratio (RR) with corresponding 95% confidence interval (CI) to determine effect sizes, and further performed statistical analyses under a randomized- or fixed-effects model. Seven studies, comprising 602 and 731 participants in the case and control group respectively, met our inclusion criteria, and were therefore included in the meta-analysis. Assessment based on Cochrane evaluation system or MINORS revealed that most of the studies had high quality. Moreover, the randomized- model revealed that the vitamin D supplementation group had a lower recurrence rate than the control group which did not accepted vitamin D supplementation (RR = 0.41, 95% CI = 0.26-0.65, p < 0.01). Overall, these findings indicate that vitamin D supplementation can significantly lower recurrence in benign paroxysmal positional vertigo and vitamin D deficiency.

The utility of brain CT scan modality in the management of dizziness at the emergency department: A retrospective single-center study

ObjectivesThis study examines the usefulness of computed tomography (CT) scans in evaluating patients with dizziness in the emergency department (ED). MethodsMedical records of patients presented with complaints of dizziness or vertigo to the ED of a tertiary university hospital and underwent head CT scans from July 2015 to June 2018 were reviewed. The patients’ demographic information, presenting symptoms, and final head CT scan and Magnetic resonance imaging (MRI) results were collected. Stepwise logistic regressions were used to analyze data. ResultsA total of 326 dizzy patients were included in this study. The majority of the patients (83.1%) were older than 44 years. Acute vertigo pattern of dizziness was detected among 50.6% of the patients and was more common among females than males (p < 0.001). Of these 326 patients who underwent head CT scans, 49 (15%) had abnormal findings with acute ischemic stroke was the most common one. A total of 191 patients underwent follow-up studies. MRI accounted for 70% of the follow-up studies. Of the 134 patients who received MRI of the brain, 36 (27%) had abnormal findings. A significant correlation of RBCs level, presence of other symptoms, and frequency of episodes with the presence of vertigo (p < 0.001) was found. ConclusionThe study's findings indicate low effectiveness of head CT scan compared to MRI for dizziness management. Future studies are suggested to provide more insights into the cost-effectiveness and utility of head CT scans and MRI in providing valuable findings.

The effectiveness of propranolol, flunarizine, amitriptyline and botulinum toxin in vestibular migraine complaints and prophylaxis: a non-randomized controlled study

IntroductionVestibular migraine is the most common cause of spontaneous episodic vertigo in adult patients and the second most common cause of vertigo in patients of all ages. ObjectiveTo assess the effectiveness of oral medication type (propranolol, flunarizine, and amitriptyline) and botulinum toxin A application on vestibular symptoms, headache severity and attack frequency for vestibular migraine patients. MethodsSixty patients with vestibular migraine were enrolled. Thirty patients received botulinum toxin A treatment (B+ group) in addition to the oral medication, whereas 30 patients received only oral medication (B− group). Headache severity was evaluated with Migraine Disability Assessment Scale and vertigo severity was evaluated with Dizziness Handicap Inventory scale. Vestibular migraine attack frequencies in the last three months were also evaluated. ResultsThere was a statistically significant decrement in mean Dizziness Handicap Inventory scores, Migraine Disability Assessment Scale scores and vertigo attack frequencies after treatment for all patients, B+ and B− group patients (p<0.001 for all). The mean Migraine Disability Assessment Scale score gains (p<0.001) and vertigo attack frequency gains (p= 0.003) were significantly higher in the B+ patients than B− patients. ConclusionsBoth B+ and B− group patients exhibited significant improvement in vestibular migraine attack frequencies, Dizziness Handicap Inventory score and Migraine Disability Assessment Scale score values. However, botulinum toxin A application had a more pronounced effect for Migraine Disability Assessment Scale score gain and vestibular migraine attack frequency values, but not for Dizziness Handicap Inventory score gain values. Thus, botulinum toxin A application should be considered for vestibular migraine patients whose headache severity degrees are more profound. The oral medication type (propranolol, flunarizine or amitriptyline) did not differ in influencing the vestibular migraine attack frequency, Dizziness Handicap Inventory score gain and Migraine Disability Assessment Scale score gain values.

The use and misuse of the Dix-Hallpike test in the emergency department

A simple bedside test, the Dix-Hallpike test (DHT), can reliably diagnose benign paroxysmal positional vertigo (BPPV) in patients with acute onset dizziness or vertigo. We evaluated patterns of DHT use by emergency physicians in patients presenting with dizziness and vertigo. Our objective was to assess the frequency and clinically appropriate use of the DHT in an emergency department. A health records review was performed using data from patients who presented to a tertiary care emergency department between September 2014 and March 2018 with a primary complaint of vertigo or dizziness. Patient records were reviewed for documentation of symptoms consistent with BPPV and DHT usage. A total of 2309 patients met inclusion criteria. Of all dizzy patients who had complete documentation of signs and symptoms consistent with BPPV, 53% were assessed with a DHT. Of 469 patients who received a DHT, 134 (29%) of tests were done on patients who had documentation of at least one characteristic that was inconsistent with a diagnosis of BPPV. Eight patients who received a DHT were ultimately diagnosed with a central cause for their vertigo. The DHT is both underutilized and frequently applied to patients whose symptoms are not consistent with BPPV. This may result in prolonged patient discomfort and increased resource utilization, as well as increasing the risk of misdiagnosing central vertigo.

Dizziness Handicap Inventory in Clinical Evaluation of Dizzy Patients.

(1) Objectives: The evaluation of dizzy patients is difficult due to nonspecific symptoms that require a multi-specialist approach. The Dizziness Handicap Inventory (DHI) is widely used in the assessment of dizziness-related disability, but its clinical efficacy needs further expansion. The aim of this study was to identify the subscales of DHI that may correlate with some vestibular or nonvestibular dysfunctions. (2) Material and methods: This observational study included 343 dizzy patients with one of the following clinical conditions: Vestibular impairment noncompensated or compensated, central or bilateral, benign paroxysmal positional vertigo (BPPV), migraine and psychogenic dizziness. Principal component analysis was used to examine the factorial structure of the questionnaire. (3) Results: The DHI questionnaire total scoring and its vestibular subscale distinguished between patients with compensated and uncompensated vestibular dysfunction with positive predictive values of 76% and 79%, respectively. The DHI items composing the F3 (positional) subscale revealed the highest scoring in the BPPV group with 75% sensitivity and 92% negative predictive value (NPV) in reference to Dix–Hallpike tests. The DHI total score and the subscales scores correlated with anxiety-depression, and the highest correlation coefficients were calculated for vestibular (F2 0.56) and anxiety (F5 0.51) subscales. (4) Conclusions: Our analysis revealed that the DHI vestibular subscale distinguishes between patients with compensated and uncompensated vestibular dysfunction. The positional subscale showed the highest scoring in the BPPV group with high sensitivity and low specificity of the test. The DHI is highly correlated with patients’ psychological status.

Subjective Cognitive Symptoms and Dizziness Handicap Inventory (DHI) Performance in Patients With Vestibular Migraine and Menière's Disease.

Cognitive symptoms in patients with vestibular disorders are far from rare, but identification of patients at risk for cognitive impairment remains poor. The Dizziness Handicap Inventory (DHI) is a widely used patient-reported outcome questionnaire for dizzy patients with several questions that address cognitive function. However, the relationship between subjective cognitive symptomatology in patients with vestibular disorders and performance on DHI is poorly characterized. Retrospective cohort study. Tertiary care vestibular clinic. Individuals with diagnoses of vestibular migraine (VM), Menière's disease (MD), and concomitant vestibular migraine and Menière's disease (VMMD) presenting to clinic between January 2007 and December 2019. Of 761 subjects, 365 had VM, 311 had MD, and 85 had VMMD. Symptoms of brain fog and chronic fatigue occurred more frequently in the VM and VMMD groups compared with the MD group (χ2 (df = 2, n = 761) = 67.8, 20.9, respectively, p < 0.0001). DHI scores were significantly higher in patients with VM and VMMD compared with those with MD (F[2,758] = 63.5, p < 0.001). A DHI score ≥ 13 suggested that the patient suffered from brain fog (sensitivity = 47.4%, specificity = 72.3%), whereas a score ≥ 15 indicated that the patient complained of chronic fatigue (sensitivity = 81.5%, specificity = 57.7%). Our results indicate a high prevalence of interictal cognitive symptoms in patients with episodic vestibular disorders. The DHI cannot be reliably used to differentiate between vestibular disorders nor detect cognitive impairment in these patient populations. Alternative methods must be used to identify vestibulopathic patients with cognitive symptoms to initiate strategies for prevention and treatment.

Lateral semicircular canal-BPPV: Prospective randomized study on the efficacy of four repositioning maneuvers

IntroductionMultiple repositioning maneuvers have been described to treat lateral semi-circular canal Benign Paroxysmal Positional Vertigo (LC-BPPV) patients. In this study, we compare efficacy of four therapeutic repositioning maneuvers for LC-BPPV patients and aim to identify clinical variables associated with persistent disease. Material and methodsA prospective study was conducted at a tertiary center, between January 2017 and September 2019. Patients diagnosed with LC-BPPV were randomly treated with Gufoni or barbecue-roll maneuvers (for the geotropic variant) and Gufoni-Appiani, barbecue-roll or Zuma-e-Maia maneuvers (for the apogeotropic form). Efficacy was compared and statistical analysis was performed to find clinical factors associated with no response. ResultsForty-eight patients and 82 maneuvers were included. Female patients and right side were more commonly affected. The mean age was 67 years. Seven cases (14.6%) resulted from a canal-switch. One single maneuver resolved 23 cases (47.9%) and the success rate rose to 75% at the end of the first visit (after up to 4 maneuvers) and to 93.8% after a-week of follow-up. Success rates were significantly better with Gufoni (68%) than with barbecue roll (34.8%; p=0.021) in geotropic LC-BPPV and better with Gufoni-Appiani (71.4%) than barbecue roll and Zuma-e-Maia maneuvers (33.3%; p=0.239) in apogeotropic LC-BPPV. Higher rates of persistent disease after first visit were found with older patients, left side and apogeotropic LC-BPPV and with longer latency and duration diagnostic nystagmus. ConclusionOur study suggests that Gufoni and Gufoni-Appiani maneuvers may be the most efficacious treatment for geotropic and apogeotropic LC-BPPV, respectively, compared to barbecue-roll and Zuma-e-Maia maneuvers.

Prevalence of anxiety and depression in dizzy patients using Arabic hospital anxiety and depression scale

ObjectivesTo develop an Arabic version of the hospital anxiety and depression scale (HADS) to detect and measure anxiety and depression prevalence in dizzy patients.BackgroundDizziness is a common complaint that has many causes and may be related to psychiatric disorders like anxiety and depression. Early detection of anxiety and depression in dizzy patients helps in proper management and a better outcome. The HADS is a valid screening tool, and having an Arabic version will be of great help.Patients and methodsThe original English HADS was translated following the cross-cultural adaptation guidelines into Arabic. The final Arabic version of HADS was administered to samples of 100 healthy control persons, 30 anxious patients, and 30 depressed patients. Reliability and validity of the translated Arabic HADS were examined. The prevalence of anxiety and depression in dizzy patients were assessed through 100 dizzy patients who were asked to complete the validated Arabic HADS.ResultsThe translated Arabic HADS was found to be reliable with strong internal consistency (Cronbach's alpha was 0.811 for the anxiety group and 0.758 for the depression group). The test–retest reliability was high (Spearman's correlation was 0.980 for the anxiety group and 0.928 for the depression group). There was a good correlation between psychiatric assessment and HADS for anxiety and depression using the Mann–Whitney test, indicating its validity. We performed the receiver operating characteristics curve, and the most sensitive cutoff point for HADS anxiety subscale was 8.5 and for HADS depression subscale was 9.5. In the dizzy group, 32% gave positive HADS scores for anxiety subscale and 22% gave positive HADS scores for depression subscale.ConclusionsThis version of the Arabic HADS is a reliable and valid psychological screening tool for anxiety and depression. The anxiety and depression prevalence in the dizzy patients was 32% and 22%, respectively.

Association of regional cerebral perfusion impairment with gait and balance performance in dizzy patients using brain perfusion SPECT: Voxel-based analysis of a pilot sample.

The purpose of this study was to investigate regional cerebral blood flow (rCBF) reduction in patients with dizziness and perfusion-related clinical impairment using brain perfusion single photon emission tomography (SPECT). Thirty-four patients with subjective dizziness and 13 age- and sex-matched healthy controls were studied. Dizziness-related impairments were assessed using the Dizziness Handicap Inventory (DHI) and Short Physical Performance Battery (SPPB). Brain perfusion SPECT scan was acquired from all participants. The carotid intima-media thickness (CIMT) was also measured. Brain perfusion data were qualitatively interpreted in all cases. Voxel-wise analysis was also conducted in 11 patients compared to healthy controls. Thirty-four patients (mean age=53.8±13.4 years, m/f: 19/15) and 13 age- and sex-matched controls (mean age=51.5±13.1, m/f: 7/6) were included. The dizziness severity was mild in 58.8% (n=20), moderate in 26.5% (n=9), and severe in 14.7% (n=5). Qualitative interpretation of SPECT images showed normal scans in 4 (11.2%) patients and abnormal scans in 30 (88.2%) patients. Patients with dizziness showed a significantly decreased brain perfusion in the precuneus, cuneus, occipital lobe (superior and inferior parts), frontal lobe (inferior and middle parts), temporal lobe, parietal lobe (inferior and superior parts), cerebellum, insula, and putamen nucleus. Based on both qualitative SPECT interpretation and voxel-wise analysis, perfusion defect had a significant association with the total SPPB score and the scores of two sub-domains (p<0.05), but not with the DHI (p>0.05) score. The perfusion- and atherosclerosis-related impairments of gait and balance were largely independent of subjective dizziness and dizziness severity. Moreover, this study provided support for contribution of perfusion impairment to the disturbance of gait and balance in older populations along with other pathologic processes.

Visual-vestibular mismatch correlates with headache.

Dizziness affects 20-30%of the general population. A subgroup of dizzy patients with chronic migraine suffers vertigo implying that the migraine has a vestibular component. Vestibular migraine remains a diagnosis of exclusion based on history. A link between headaches and dizziness suggests that these individuals would demonstrate dizziness and instability in complex, dynamic visual environments as a result of an inability to correctly process conflicting visual and vestibular signals. A convenience sample of 74 patients (22 men and 52 women; average age 56.2 years) who presented with complaints of dizziness participated. Effects of Visual-Vestibular Mismatch (VVM) were measured using a modified VVM questionnaire. Visual dependence was measured as the error to subjective visual vertical using a computerized Rod and Frame test. Forty-two participants (56.8%) tested positive for VVM. Of these, 68.9%were patients with concomitant complaints of headaches. Visual dependence was present in 41.5%of all patients but showed no significant correlation with headache. 22.2%of patients had visual dependence and complained of headaches. These results demonstrate that sensory reweighting occurs in patients experiencing dizziness and headache, supports the role of vestibular involvement in this disorder, and provides future direction for novel interventions.

Teleconsultation and Teletreatment Protocol to Diagnose and Manage Patients with Benign Paroxysmal Positional Vertigo (BPPV) during the COVID-19 Pandemic.

Introduction Telehealth consists in the application of technology to provide remote health service. This resource is considered safe and effective and has attracted an exponential interest in the context of the COVID pandemic. Expanded to dizzy patients, it would be able to provide diagnosis and treatment, minimizing the risk of disease transmission. Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder. The diagnosis typically rests on the description of the symptoms along with the nystagmus observed at a well-established positional testing. Objectives The aim of the present study was to propose a teleconsultation and teletreatment protocol to manage patients with BPPV during the COVID-19 pandemic. Methods Specialists in the vestibular field met through remote access technologies to discuss the best strategy to manage BPPV patients by teleconsultation and teletreatment system. Additionally, several scientific sources were consulted. Technical issues, patient safety, and clinical assessment were independently analyzed. All relevant information was considered in order to design a clinical protocol to manage BPPV patients in the pandemic context. Results Teleconsultation for BPPV patients requires a double way (video and audio) digital system. An adapted informed consent to follow good clinical practice statements must be considered. The time, trigger and target eye bedside examination (TiTRaTe) protocol has proven to be a valuable first approach. The bow and lean test is the most rational screening maneuver for patients with suspected positional vertigo, followed by most specific maneuvers to diagnostic the sub-variants of BPPV. Conclusion Although with limited evidence, teleconsultation and teletreatment are both reasonable and feasible strategies for the management of patients with BPPV in adverse situations for face-to-face consultation.

Alat Deteksi Jatuh Berbiaya Murah Dengan Tracking Position Untuk Pasien Vertigo dan Sinkop

In this study we propose a low-cost portable device to monitor the vertigo and syncope patients whether normal, dizziness or falls. The purpose of this study is design and manufactures a device using an accelerometer sensor to determining the condition of patients who are at risk of vertigo and syncope. The patient's condition is detected by accelerometer which read the values of the x, y and z axes to determine condition normal, dizzy, or fall. This device also uses a real time clock to remind the patient to take medication three times a day. The device outputs are LCD Oled, Voice, and SMS notification. If the patient condition is falls an SMS notification will be sent, the dizzy condition vertigo patient will press the panic button first and then an SMS notification will be sent. The results of tests carried out on the equipment can send SMS and phone calls at an angle of (50o - 70o) = Y (40o - 20o) = X, in a fainting state and falling. The test results of the navigation module prove that the GPS module can determine the exact location by moving the GPS module reading position to a small test point with an average of 2.97 meters.

The Bucket Test Improves Detection of Stroke in Patients With Acute Dizziness.

It is challenging to detect posterior circulation strokes in patients presenting to the emergency department (ED) with acute dizziness. The current approach uses a combinatorial head-impulse, nystagmus, and test-of-skew method and is sensitive enough to differentiate central causes from peripheral ones. However, it is difficult to perform and underused. Further, magnetic resonance imaging (MRI) of the brain is not always available and can have low sensitivity for detecting posterior circulation strokes. We evaluated the feasibility and utility of the bucket test (BT), which measures the difference between patient's subjective perception of the visual vertical and the true vertical, as a screening tool for stroke in patients presenting to the ED with acute dizziness. In this work, we prospectively enrolled 81 patients that presented to our academic medical center ED with dizziness as their chief complaint. The BT was performed 3 times for every patient. Seventy-one patients met the study criteria and were included in the analysis. Ten patients were excluded because of a history of drug-seeking behavior. There were no reported difficulties performing the BT. Six patients (8%) were diagnosed with ischemic stroke on MRI and 1 additional patient was diagnosed with transient ischemic attack and found to have a stroke on subsequent MRI. All 7 patients with dizziness attributed to cerebrovascular etiology had an abnormal BT, resulting in a sensitivity of 100% (95% confidence interval [CI] 59-100%). The specificity of the BT was 38% (95% CI 24-52%). The positive predictive value of the BT for detecting stroke was 18% (95% CI 15-21%). The BT is an easy, cheap, safe, and quick test that is feasible and sensitive to screen acutely dizzy patients for stroke in the ED.

Diagnostic Accuracy of the HINTS Exam in an Emergency Department: A Retrospective Chart Review.

The HINTS exam is a series of bedside ocular motor tests designed to distinguish between central and peripheral causes of dizziness in patients with continuous dizziness, nystagmus, and gait unsteadiness. Previous studies, where the HINTS exam was performed by trained specialists, have shown excellent diagnostic accuracy. Our objective was to assess the diagnostic accuracy of the HINTS exam as performed by emergency physicians on patients presenting to the emergency department (ED) with a primary complaint of vertigo or dizziness. A retrospective cohort study was performed using data from patients who presented to a tertiary care ED between September 2014 and March 2018 with a primary complaint of vertigo or dizziness. Patient characteristics of those who received the HINTS exam were assessed along with sensitivity and specificity of the test to rule out a central cause of stroke. A total of 2,309 patients met criteria for inclusion in the study. Physician uptake of the HINTS exam was high, with 450 (19.5%) dizzy patients receiving all or part of the HINTS. A large majority of patients (96.9%) did not meet criteria for receiving the test as described in validation studies; most often this was because patients lacked documentation of nystagmus or described their symptoms as intermittent. In addition, many patients received both HINTS and Dix-Hallpike exams, which are intended for use in mutually exclusive patient populations. In no case was dizziness due to a central cause identified using the HINTS exam. Our results suggest that despite widespread use of the HINTS exam in our ED, its diagnostic value in that setting was limited. The test was frequently used in patients who did not meet criteria to receive the HINTS exam (i.e., continuous vertigo, nystagmus, and unsteady gait). Additional training of emergency physicians may be required to improve test sensitivity and specificity.

VESTIBULAR SYMPTOMS AFTER COCHLEAR IMPLANTATION: CLINICAL OVERVIEW AFTER A 2-YEAR FOLLOW-UP

Background Vestibular symptoms and balance disorders are still common complaints reported by the patients after cochlear implantation (CI). Much research has been devoted to assess dizzy patients after cochlear implantation using both self-prepared questionnaires as well as validated life-quality scales. From this work, various approaches to classifying symptoms according to their onset and duration have been recommended. Material and methods We studied 101 patients after round window approach (RWA) cochlear implantation giving them a self-prepared questionnaire asking them to list their major vestibular complaints formulated according to the consensus document of the Barany Society Committee for the classification of vestibular disorders. Those with persistent symptoms (both postoperatively and existing preoperatively) also filled in a DHI questionnaire. Additionally, cVEMP, oVEMP, caloric, and vHIT tests were performed before and after the CI procedure. Results The 101 patients were divided into four groups: with early symptoms (n = 25), with late symptoms (n = 2), with preoperative symptoms (n = 13), and with no symptoms (n = 61). Among the patients with early symptoms, 15 reported spontaneous vertigo attack, 6 only unsteadiness and/or lateropulsion, and 4 had other symptoms such as orthostatic vertigo, positional vertigo, visual tilt, and head-motion vertigo. Conclusions Close to 40% of the CI recipients suffered from vestibular complaints, either in the postoperative period or from already existing preoperative symptoms. The vast majority of postoperative complaints were transient and only rare cases (with preexisting inner ear pathologies and/or comorbidities) evolved into persistent dysfunction.

Examination Approach to the Dizzy and Swaying Patient.

BackgroundDizziness is a common presenting complaint among patients in Malaysia. It is a vague term which could be associated with vertigo, imbalance, ataxia or syncope. In order to deal with this overwhelming complaint, a detailed history-taking is essential in confirming aetiology of disease and this should be followed by a meticulous clinical examination. The purpose of the video manuscript it to provide a step-by-step approach to a dizzy and swaying patient, specially catered for Malaysian medical students and trainees.MethodsA series of videos were shot, which involved the eye, ear, vestibular system, cerebellar, proprioceptive sense and gait examination. These videos, conducted in Universiti Sains Malaysia (USM) School of Medical Sciences, will be first in Malaysia and will highlight the proper technique and rapport with patients and essential points of each examination. There will be summary at the end of each examination on how to report findings which is a common weakness among students.ConclusionWe hope that students and junior doctors could be apply these methods in their daily assessment of dizzy patients and ultimately, reach an accurate diagnosis.

Transitional nystagmus in a Bow Hunter\u2019s Syndrome case report

BackgroundBow Hunter’s Syndrome (BHS) is known as one of cervical diseases which causes vertigo, but the details of its vertigo, especially nystagmus and eye movement, are still incompletely understood. This time, we reported the first case of BHS with a nystagmus chart with video record of transitional nystagmus.Case presentationThe patient, a 47-year-old female, complained of vertigo caused by head rotation. When she turned her head leftward, leftward nystagmus appeared, and this was followed by dullness of the right arm. After her head was returned to the central position, downbeat nystagmus appeared, which changed to rightward nystagmus. She was diagnosed with BHS by her symptoms and images. We recorded a nystagmus video and nystagmus chart of this transitional nystagmus including downbeat nystagmus. Her vertigo was cured by the modification of a prescription for her past medical history: hypertension.ConclusionThe vertigo of BHS accompanies nystagmus. In this present case, the transitional nystagmus was observed, and it occurred toward the healthy side. Then the nystagmus direction was changed to the affected side via downbeat nystagmus. This is the first report with both a nystagmus chart with video of BHS. Nowadays, various kinds of vertigo induced by neck movement are known. BHS is a rare disease among vertigo diseases, but we should consider it as a different diagnosis of vertigo patients. A precise interview and proper examination are required to make the final diagnosis.
