Assessment of micronutrients in pediatric vertigo

Aim: This study aimed to evaluate the clinical characteristics of patients admitted to the pediatric neurology outpatient clinic with the complaint of vertigo and to investigate the role of micronutrients in the etiology of vertigo Materials and Methods: This study retrospectively evaluated the patients aged four to 18 years who were admitted to the pediatric neurology outpatient clinic with the complaint of vertigo to evaluate the clinical characteristics and the role of micronutrients in the etiology of vertigo. Patients, for whom the Z00.1 code, the routine child health examination code, was entered in the pediatric outpatient clinic in the same period when the patients presented with the complaint of vertigo were included as the healthy control group. Hemogram and hormone profiles [25(OH)D, FT4, TSH, vitamin B12, folic acid and ferritin] of the groups were compared. Results: There was no statistically significant difference between the study group and healthy controls in terms of age and gender. Hematocrit (p<0.001), platelet (p<0.001), vitamin B12 (p=0.015), vitamin D (p=0.043) and TSH (p=0.013) levels were found to be significantly lower in the vertigo group compared to the control group. Conclusion: The importance of micronutritional deficiencies cannot be denied in patients presenting with vertigo symptoms. Main point that makes our study valuable is that there are limited number of studies in the literature comparing laboratory parameters of pediatric patients with vertigo symptoms and healthy controls. There is a need for prospective studies, involving more cases and awareness on this issue.

Current Demography and Treatment Strategy of Vestibular Migraine in Neurotologic Perspective.

This study aims to describe the demographic features of vestibular migraine (VM) compared to other common peripheral vestibulopathies, and to assess the efficacy of trigger management as primary VM treatment. Retrospective study. Tertiary referral medical center. A retrospective chart review was performed of patients presenting with dizziness in a tertiary neurotology clinic. Among the newly diagnosed dizzy patients, those with a diagnosis of either VM, Ménière's disease, benign paroxysmal positional vertigo, or vestibular neuritis/labyrinthitis were selected for comparisons of the disease demographics. VM patients with multiple clinic visits in the study period were included for the treatment strategy analysis. A total of 1285 patients met the study inclusion criteria. In the newly diagnosed dizzy group comprising 814 patients, VM patients accounted for the largest (25%) and youngest (mean age 47 years) cohort, showing an obvious female preponderance of approximately 3.3:1. Furthermore, prevalence of VM declined significantly with advancing age, from 69%, to 34%, to 11%, in age groups of ≤30, 31 to 60, and >60 years, respectively. Trigger management, when employed as the primary VM first-year treatment, was effective for both sexes. Notably, it was more effective for women aged over than under 45 years. In our tertiary referral neurotologic center, VM was the most common diagnosis in newly diagnosed dizzy patients aged under 60 years, especially in women. For primary VM treatment, trigger management is an effective option deserving consideration.

Translation and Validation of the Niigata PPPD Questionnaire into Tamil: A Tool to Assess Persistent Postural-Perceptual Dizziness.

PPPD is a chronic and functional disorder without diagnostic data and definitive laboratory tests. In such conditions, questionnaires are the easiest quantifiable measures to identify and rate the severity of individuals suffering from PPPD. The current study aimed to adapt the Niigata PPPD Questionnaire (NPQ) into Tamil language and analyze its psychometric properties. A conventional method of translation involving forward and backward translation was carried out, followed by subsequent content validation. The translated version was field tested in three groups, the controls, the dizzy group, and PPPD group, for further analysis. The final Tamil version of the questionnaire, NPQ-T, had good reliability and validity. This version was identified to have good sensitivity and specificity in discriminating the PPPD group from the dizzy group. The NPQ in Tamil (NPQ-T) is a valid tool for identifying individuals with PPPD and noting the severity of the exacerbating factors.

Therapeutic efficacy of methylprednisolone sodium succinate via diverse administration routes for mid- to high-frequency sudden sensorineural hearing loss

BACKGROUND Sudden sensorineural hearing loss (SSNHL), characterized by a rapid and unexplained loss of hearing, particularly at moderate to high frequencies, presents a significant clinical challenge. The therapeutic use of methylprednisolone sodium succinate (MPSS) via different administration routes, in combination with conventional medications, remains a topic of interest. AIM To compare the therapeutic efficacy of MPSS administered via different routes in combination with conventional drugs for the treatment of mid- to high-frequency SSNHL. METHODS The medical records of 109 patients with mid- to high-frequency SSNHL were analyzed. The patients were divided into three groups based on the route of administration: Group A [intratympanic (IT) injection of MPSS combined with mecobalamin and Ginkgo biloba leaf extract injection], Group B (intravenous injection of MPSS combined with mecobalamin and Ginkgo biloba leaf extract injection), and Group C (single IT injection of MPSS). The intervention effects were compared and analyzed. RESULTS The posttreatment auditory thresholds in Group A (21.23 ± 3 .34) were significantly lower than those in Groups B (28.52 ± 3.36) and C (30.23 ± 4.21; P < 0.05). Group A also exhibited a significantly greater speech recognition rate (92.23 ± 5.34) than Groups B and C. The disappearance time of tinnitus, time to hearing recovery, and disappearance time of vertigo in Group A were significantly shorter than those in Groups B and C (P < 0.05). The total effective rate in Group A (97.56%) was significantly greater than that in Groups B and C (77.14% and 78.79%, χ 2 = 7.898, P = 0.019). Moreover, the incidence of adverse reactions in Groups A and C was significantly lower than that in Group B (4.88%, 3.03% vs 2.57%, χ 2 = 11.443, P = 0.003), and the recurrence rate in Group A was significantly lower than that in Groups B and C (2.44% vs 20.00% vs 21.21%, χ 2 = 7.120, P = 0.028). CONCLUSION IT injection of MPSS combined with conventional treatment demonstrates superior efficacy and safety compared to systemic administration via intravenous infusion and a single IT injection of MPSS. This approach effectively improves patients' hearing and reduces the risk of disease recurrence.

Preliminary observation of wearable balance diagnosis and treatment system in evaluating dynamic and static balance function in patients with vestibular vertigo

A newly developed wearable balance diagnosis and treatment system was studied to evaluate the indexes of the abnormal balance function in patients with vestibular vertigo. A cross-sectional study was carried out. A total of 30 patients diagnosed with non-acute vestibular vertigo in the outpatient department of Eye, Ear, Nose and Throat Hospital Affiliated to Fudan University from July 2022 to May 2023 were selected as the vertigo group, including 13 males and 17 females, and aged (45.7±13.9) years. Meanwhile, 20 healthy controls (8 males and 12 females) were included as the control group, with a mean age of (43.6±8.0) years. The static balance and limits of stability (LOS) function of all subjects were assessed with wearable balance diagnosis and treatment system developed under the leadership of Eye & ENT Hospital of Fudan University. In the static balance test, the ratio of eyes open with cushions to eyes open without cushions in the vertigo group was less than that of the control group[1.20% (0.92%, 1.53%) vs 1.49% (1.22%, 1.81%), P=0.008], indicating that patients with non-acute vestibular vertigo may compensate static balance ability earlier. In vertigo group, the directional control in 8 directions, the maximum excursion in anterior, posterior, right anterior and right posterior directions, the endpoint excursion in the posterior, right posterior, and left posterior directions were all smaller than those of the control group (all P<0.05). The reaction time in the left posterior direction of vertigo group was longer than that of the control group (all P<0.05). Those results indicated that the directional control, maximum excursion and endpoint excursion of LOS could be considered as important reference indexes for dynamic balance function.

The clinical significance of arterial stiffness in the differential diagnosis of vertigo

Objectives: Pulse wave velocity (PWV) is a known indicator of arterial stiffness reflecting vascular damage. However, there are few reports of the relationship between PWV and dizziness/vertigo of a vascular origin. We investigated whether the PWV value could be useful as an ancillary measurement for identifying the etiology of dizziness/vertigo.Methods: We enrolled dizzy patients from March 2016 to December 2018. The patients with posterior circulation stroke presenting with dizziness/vertigo were categorized as having central vertigo. The patients with vertigo due to benign paroxysmal positional vertigo, Ménière disease, or acute unilateral vestibulopathy were categorized as having peripheral vertigo. The PWV value, ankle-brachial index (ABI), and traditional vascular risk factors were collected.Results: We consecutively enrolled a total of 93 participants. The PWV values were higher in the central vertigo group (p&lt;0.001), but ABI did not differ between the groups. Among the vascular risk factors, the number of patients with diabetes mellitus, dyslipidemia, and male patients was significantly higher in the central vertigo group. The brachial-ankle PWV (baPWV) values were higher in the central vertigo group, even after adjusting for confounding factors (p&lt;0.01). The receiver operating characteristic curve showed that the sensitivity was 74% and specificity was 81% when the mean baPWV value was 14.78 m/sec.Conclusions: Increased baPWV values were observed in patients with dizziness/vertigo due to stroke. Measurement of the baPWV value could be an ancillary test for evaluating the cause of dizziness/vertigo, even though more convincing evidence is still required.

Hybrid dizziness counseling with vestibular rehabilitation in participants with chronic dizziness: a comparison of dizziness handicap

IntroductionPatients with chronic dizziness often have an unremarkable laboratory vestibular examination and have medical clearance from other specialties. However, functional impairments are still significant and affect patients' quality of life. Recent diagnostic criteria and identification of persistent postural perceptual dizziness (PPPD) have helped us to better understand the psychological-somatic manifestations of organic disorders. As the literature suggests good efficacy using a combination of cognitive behavior therapy (CBT) and vestibular rehabilitation, we compared the efficacy of a hybrid protocol using dizziness handicap inventory (DHI) as an outcome measure amongst the different sub-types of chronic dizziness.MethodsThis was an observational study with 35 participants allocated to three different groups: those who strictly fulfilled the PPPD criteria, those with spontaneous episodic vestibular syndrome, and participants with non-specific dizziness. We compared the DHI total and sub-domain scores at baseline and 6 months post-intervention for differences. All participants undertook three sessions in 6 months.ResultsThe total DHI scores were reduced in all three groups. However, the DHI total on average was 11 points higher in the episodic vestibular syndrome group. The emotional sub-domain scores were also reduced in all three groups, but the functional and physical scores were significantly higher in the episodic vestibular group.ConclusionA hybrid protocol worked best for typical PPPD patients who strictly fulfilled the criteria followed by participants in the non-specific dizziness group. When symptoms were episodic in spontaneous vestibular syndrome, only emotional handicap was reduced at 6 months, but functional and physical handicap scores remained high. Regardless, the DHI total scores in all groups were significantly reduced, possibly due to CBT reducing the anxiety that results from a lack of understanding of the clinical diagnoses.

Effect of subanesthetic dose of esketamine on postoperative rehabilitation in elderly patients undergoing hip arthroplasty

ObjectiveThe majority of individuals with femoral neck fractures opt for total hip replacement to enhance their quality of life. However, this group frequently exhibits perioperative symptoms of pain, anxiety, and sadness, which extends recovery time to some extent. Esketamine, the right-handed monomer of ketamine, is more popular these days due to its sedative, analgesic, and antidepressant properties. There are currently few domestic and international research on the use of esketamine in elderly individuals who have undergone surgery for a femoral neck fracture. In order to further cut the length of the hospital stay and hasten postoperative recovery, this study investigates whether esketamine postoperative analgesia can lessen postoperative pain, anxiety, and depression in older patients having hip replacement.Methods150 patients, ASA physical status I–II, aged ≥ 60 years, no limitation in gender, BMI 18–25 kg/cm2, who underwent selective total hip arthroplasty, according to random number table method, esketamine group (group A) and sufentanil group (group B) were randomized, 75 patients in each group. The two groups received general anesthesia method. At the end of the operation, PCIA was connected for analgesia. In group A, esketamine 2.5 mg/kg was mixed with normal saline to 100 ml. In group B, sufentanil 2.5 ug/kg was mixed with normal saline to 100 ml. Record the VAS scores after operation. Record the first ambulation time, ambulation distance and Patient-controlled Analgesia compression times after operation. The incidence of postoperative adverse reactions such as drowsiness, dizziness, nausea and vomiting, multilingual were recorded. ELISA was used to detect IL-6 and CRP in the morning, 24 h and 72 h after operation. The Hospital Anxiety and Depression Scale (HAD) score and Harris score at 3 days, 1 week and 1 month after operation were followed up.ResultsThere was no significant difference in VAS score and PCA compression times (P > 0.05), but the incidence of nausea, vomiting and dizziness in group B was higher than that in group A (P < 0.05). Compared with group B, the levels of IL-6 and CRP in group A at 24 h and 72 h after operation were significantly decreased (P < 0.05). Postoperative ambulation time and ambulation distance in group A were better than those in group B (P < 0.05). The HAD score of group A was lower than that of group B at 3 days and 1 week after operation (P < 0.05). However, there was no significant difference between the two groups at 1 month after operation (P > 0.05). The Harris score of group A was higher than that of group B at 3 days, 1 week and 1 month after operation (P < 0.05).ConclusionsEsketamine can reduce short-term postoperative anxiety and depression, relieve postoperative pain and stress response, shorten bed rest time after total hip replacement, and accelerate postoperative recovery.

Peripheral smell regions in patients with central vertigo: An MRI evaluation

Abstract OBJECTIVES. We investigated peripheral smell regions in patients with central vertigo by cranial magnetic resonance imaging (MRI). MATERIAL AND METHODS. In this study, 137 adult patients were included by selecting cranial MRI images from the hospital’s PACS system, covering both recent and past records. The first group included 68 adult patients suffering from central vertigo, and the control group (Group 2) 69 healthy individuals, who had no central vertigo. Measurements of olfactory bulb (OB) volume and olfactory sulcus (OS) depth were taken from all groups. RESULTS. The study found that the OB volume of the group with central vertigo was significantly lower compared to the control group (p&lt;0.05). However, there were no significant differences in the OS depth between the two groups (p&gt;0.05). In both groups, there were no significant variations in OB volume between the right and left sides (p&gt;0.05). Additionally, both the central vertigo group and the control group showed that the left OS depth was lower than the right side (p&lt;0.05). Positive correlation was seen between OB volume and OS depth on both left and right sides as well as bilateral OB volume and OS depth in the central vertigo group. However, there were no significant correlations between OB volume, OS depth and age and gender in the central vertigo group. CONCLUSION. We concluded that OB volume got lower in patients with central vertigo. However, there were no side differences between OB volumes. As central vertigo secondary to cerebral ishchemia causes olfactory disorders, measures should be taken to prevent central vascular problems. From another perspective, olfactory problems may be one of the initial signs of central vascular problems and central vertigo.

Brandt-Daroff Exercise versus Standard Technique on Symptoms Experienced by Patients with Benign Paroxysmal Positional Vertigo in a tertiary Care hospital: A Comparative Study

INTRODUCTION: Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo. It’s considered to be the most common cause of vertigo among the elderly, since 30% of the people reported to have suffered from it at least once in their lifetime.Several studies have indicated that physical therapy, including rehabilitative exercises and physical maneuvers, is an effective treatment for BPPV. Therefore, the objectives of the study was designed to compare Brandt-Daroff exercise versus standardized technique on symptoms experienced by patients with Benign paroxysmal positional vertigo (BPPV) in a selected hospital of Bangalore, India. MATERIALS AND METHODS: The post-test only group design was adopted for this study. The setting was ENT OPD of St. John’s Medical College Hospital. A sample of 20 BPPV patients in each Group 1 and Group 2 were taken using purposive sampling technique. A dizziness handicap inventory scale, a visual analogue scale and a checklist was used to assess the symptoms of patients with BPPV. RESULTS: Median score of dizziness in group 1 was 37 and in group 2 was 16, the obtained Mann Whitney value was 13, which is statistically significant at p&lt;0.001. Likewise, median score for nausea in group 1 was 3 and in group 2 was 0, the obtained Mann Whitney value was 108.5 which is statistically significant at p&lt;0.0001. Further, finding depicts that there was no statistically significant difference of vomiting between group 1 and group 2. CONCLUSIONS: there was a substantial difference in the degree of nausea and dizziness between groups 1 and 2. Group 1 had higher median scores for nausea and dizziness when compared to group 2. However, the frequency of vomiting did not differ substantially between the two groups.

An evaluation of patients who present to the emergency department with dizziness

This study aimed to analyze the data of patients presenting with dizziness at our hospital’s emergency department (ED) by determining the etiology of dizziness and to contribute to the medical data of our country and the literature. This prospective study was conducted with 116 volunteering patients who presented to the Emergency Department of Afyon Kocatepe University, Faculty of Medicine for one year with dizziness complaints. After the anamnesis, physical examination, diagnostic tests (blood tests, Dix-Hallpike maneuver, audiological-vestibular tests, carotid-vertebral artery color Doppler ultrasonography, and computerized brain tomography), and psychiatric interrogation, the patients were divided into four etiology groups: Peripheral, central, psychogenic, and other causes of dizziness. Clinical features were compared between peripheral and central dizziness groups. A total of 116 (3.4%) of patient admissions to the emergency department complained of dizziness. Forty-nine (42.2%) of these patients were male, 67 (57.8%) were female. In the cohort, 33.9% were under 40, and dizziness increased with older age. Seventy (60.3%) patients had no formal education or were primary school graduates. The initial evaluation at the ED revealed that dizziness mostly shifted with the position (71.6%) and was mainly accompanied by headache (67.2%). Based on their diagnosis, 50 patients (43.1%) were in the peripheral group, 30 patients (25.8%) were in the central group, 22 patients (19%) were in the psychogenic dizziness group, and 14 patients (12%) were in the other causes group. Intergroup analysis between peripheral and central vertigo groups identified that the hearing loss, ear fullness, recent upper respiratory tract infection (URTI), nausea, vomiting, and shifting position was statistically significant (p&lt;0.05). Dizziness is one of the common complaints of admission to the ED and may arise from different etiologies. Our study demonstrated that psychogenic dizziness was common in this patient cohort.

New onset episodic vertigo as a presentation of vestibular neuritis.

ObjectiveVestibular neuritis (VN) is a common peripheral cause of acute vestibular syndrome, characterized by sustained vertigo and gait instability, persisting from 1 day to several weeks. With the widespread use of comprehensive vestibular function tests, patients with VN and non-sustained vertigo have drawn attention. In this study, we retrospectively analyzed the clinical presentation of patients with VN and episodic vertigo, aiming to expand the atypical clinical features of VN.MethodsThis retrospective study enrolled 58 patients with VN. Among them, 11 patients with more than 3 remissions per day, each lasting over 1 h were assigned to the episodic vertigo (EV) group, and 47 subjects without significant relief into the sustained vertigo (SV) group. Demographic information, clinical manifestations and data of supplementary examinations were collected and statistically analyzed. These patients were followed up 1 year after discharge to gather prognostic information.ResultsThe incidence of spontaneous nystagmus (SN) and proportion of severe vertigo (Dizziness Handicap Inventory questionnaire score >60) in the SV group were significantly higher than those in the EV group. Spearman correlation showed that with a longer disease course, the velocity of overt saccade was smaller (p < 0.05, Rs = −0.263) in all patients with VN.ConclusionThe non-sustained manifestations in VN overlap with a wider spectrum of other vestibular disorders and stroke-related vertigo, which add an additional layer of complexity to the differential diagnosis of new onset episodic vertigo. By retrospectively analyzing the clinical characteristics and vHIT parameters, our study has expounded on the atypical features and potential pathophysiological mechanism of episodic syndromes in VN. VOR gain and saccades measured by vHIT could be reliable indicators for vestibular rehabilitation process.

Assessment of palpitation complaints in patients with benign paroxysmal positional vertigo.

The detection of cardiac arrhythmias during vertigo attacks along with the resolution of vertigo by treating the arrhythmias is defined as cardiac vertigo. The cause of palpitations that develop following attacks of non-cardiac vertigo is unknown. We aimed to investigate the effect of benign paroxysmal positional vertigo (BPPV) on the cardiac conduction system and evaluate patients' palpitation complaints using 24-hour ambulatory ECG (Holter) monitoring. Sixty-five patients with BPPV and forty-eight healthy controls were included in the study. ECG was performed on all participants, and ECG parameters were measured. Holter monitoring was performed, and the recordings were analyzed. Evaluation of the time-domain heart rate variability (HRV) results was done. The average age of the vertigo group was 49.1 ± 7.8 years. In terms of demographic or laboratory data, there was no statistically significant difference between the groups (p>0.05). The study group's ECG parameters, including Pd, TpTe, and TpTec, were longer, and the TpTe/QT and TpTe/QTc ratios were higher (p<0.05). Holter monitoring detected abnormal rhythms in 41 (63%) of the study group patients and three (6.2%) of the control group patients. The SDNN, LF, and LF/HF values, which are known as HRV markers, were significantly different in the vertigo group compared to the control group (p<0.001). This study revealed that the risk of arrhythmias increased following attacks of BPPV in patients without a known history of cardiac vertigo.

Risk of future stroke in patients with a diagnosis of peripheral vertigo in the emergency department.

The temporal characteristics of stroke risks were evaluated in emergency department patients who had a diagnosis of peripheral vertigo. It was also attempted to reveal the stroke risk factor amongst those with peripheral vertigo. This is a parallel-group cohort study in a tertiary referral hospital. After assigning each of 4367 matched patients to the comparative set of peripheral vertigo and appendicitis-ureterolithiasis groups and each of 4911 matched patients to the comparative set of peripheral vertigo and ischaemic stroke groups, the relative stroke risk was evaluated. In addition, to predict the individual stroke risk in patients with peripheral vertigo, any association between the demographic factors and stroke events was evaluated in the peripheral vertigo group. The peripheral vertigo group had a higher stroke risk than the appendicitis-ureterolithiasis group (hazard ratio 1.73, 95% confidence interval 1.18-2.55) but a lower risk than the ischaemic stroke group (hazard ratio 0.30, 95% confidence interval 0.24-0.37). The stroke risk of the peripheral vertigo group was just below that of small vessel stroke. The stroke risk of the peripheral vertigo group differed markedly by time: higher within 7 days, moderate between 7 days and 1 year, and diminished thereafter. Old age (>65 years), male gender and diabetes mellitus were the risk factors for stroke in the peripheral vertigo group. Patients with a diagnosis of peripheral vertigo in the emergency department showed a moderate future stroke risk and so a stroke preventive strategy tailored to the timing of symptom onset and individual risk is required.

Prevalence and Risk Factors of Sarcopenia in Patients with Dizziness.

This study aimed to investigate the prevalence of sarcopenia and factors associated with sarcopenia in patients with dizziness. This is a cross-sectional study. A total of 162 patients 65 years or older with the chief complaint of dizziness or vertigo (dizziness group) and 132 community-dwelling elderly (control group) were recruited during their visit to the otolaryngology clinic between May 2020 and October 2021. Of the 162 patients with dizziness (dizziness group), 53 (32.7%) were classified as sarcopenia according to the 2019 criteria of the Asian Working Group for Sarcopenia. There were significant differences in the prevalence of sarcopenia between the dizziness group and the control group ( p < 0.01). The factors that significantly affected the sarcopenia, in order of greater odds ratio, were HADS_A, age, and DHI_Total (odds ratio = 1.223, 1.130, and 1.022, respectively). The present study shows that (i) the prevalence of sarcopenia in patients with dizziness is higher than a community-dwelling elderly; (ii) patients with dizziness and sarcopenia have higher DHI_functional, DHI_emotional, DHI_total, and HADS_A compared with patients with dizziness but without sarcopenia; and (iii) age, HADS_A, and DHI were associated with sarcopenia in patients with dizziness.

Subjective perception of activity level: A prognostic factor for developing chronic dizziness after vestibular schwannoma resection?

IntroductionA vestibular schwannoma (VS) resection causes an acute unilateral vestibular deafferentation resulting in acute postoperative symptoms. Despite the expected resolution of most of the symptoms, due to central vestibular compensation, more than one out of four patients develop chronic dizziness. Several predictive factors, such as age and tumor size, have been suggested. Despite its potential effect on the process of central vestibular compensation, the level of physical activity after VS resection was not yet considered. Therefore, the association between the level of physical activity and chronic dizziness after VS resection will be investigated.MethodsThis retrospective cohort study included 66 patients who underwent a retro-sigmoid VS resection between October 2001 and February 2007. Patients were assessed before surgery and at 9 weeks and 6 months postoperatively. At 9 weeks, patients were asked to report their level of physical activity (PA) during the past week by using a visual analogue scale and their balance performance was assessed by four standing balance conditions with eyes closed and the Timed Up and Go test (TUG). Based on the Dizziness Handicap Inventory (DHI) score at 6 months, patients were divided in a chronic dizziness group (DHI > 30) and non-chronic dizziness group (DHI-score ≤ 30). Age, sex, Koos classification, preoperative vestibular function, treatment group, balance performance, and level of PA were compared between both groups and used as independent variables in linear regression analyses with the DHI score at 6 months as dependent variable.ResultsThe chronic dizzy patients revealed to have significantly lower levels of PA (p < 0.001) and worse static and dynamic balance performance (p = 0.023 and p = 0.041, respectively) 9 weeks after surgery. After elimination, the multiple regression analysis resulted in a model with two variables (PA level, TUG) which significantly predicted the DHI score (F2,42 = 6.581; R2 = 0.239; p = 0.003).ConclusionThis study revealed associations between (1) the level of PA and balance performance in the subacute phase and (2) chronic dizziness after VS resection. Assessment of the level of PA and balance performance during the subacute phase, which can be performed in a non-invasive and non-time-consuming way, might therefore provide prognostic information after VS resection.

Correlation Analysis of Vestibular Symptoms and Migraine and Non-migraine Headaches: An Epidemiological Survey of 708 Female Nurses.

ObjectiveThis study is oriented to study the correlation between different vestibular symptoms and migraine and non-migraine headaches.Materials and MethodsA questionnaire containing factors related to vestibular symptoms and migraine was designed to survey nurses in a tertiary hospital. Then, all study subjects were divided into three groups: no headache, migraine, and non-migraine headache, and the general physical condition and incidence of different vestibular symptoms were compared among the three groups.ResultsAmong all the 708 subjects, 233 had headaches. The incidence of migraine was 13.3%. There were 235 cases had vestibular symptoms. Dizziness and vertigo are independent factors related to headaches, especially migraine. The risk of migraine and other types of headaches in the vertigo group is 2.808 and 2.526 times of those without vertigo, while in the dizziness group, the risk is 8.248 and 5.732 times of those without dizziness.ConclusionDifferent vestibular symptoms were all related to migraine. And different vestibular symptoms and non-migraine headaches also showed a clear correlation.

Dizziness Is Associated With Neck/Shoulder Pain Following Pediatric Concussion.

To examine the association between dizziness and neck/shoulder pain after concussion and if differences in postural stability and oculomotor function exist among patients reporting dizziness with or without concurrent neck/shoulder pain. Cross sectional. Sports medicine clinic. Pediatric patients ≤14 days post concussion. N/A. Patients completed the Health and Behavior Inventory (HBI) symptom rating and separately rated neck/shoulder pain (scale 0-3; 0 = no pain). We grouped patients by HBI dizziness rating (0 = not-dizzy; 1-3 = dizzy) and compared neck/shoulder pain ratings between the groups. We then compared oculomotor and postural stability outcomes between dizzy patients with and without neck/shoulder pain. We included 153 patients: dizzy (n = 100; age = 14.6 ± 2.2 years; 48% female) and not-dizzy (n = 53, age = 14.4 ± 3.1 years; 38% female). The dizzy group reported significantly higher neck/shoulder pain (1.4 ± 1.1 vs 0.5 ± 0.9 points, P < 0.001) and total symptom score (25.7 ± 11.2 vs 11.7 ± 9.3 points, P < 0.001) than the not-dizzy group. After adjusting for total symptom score and preinjury anxiety, depression, and migraines, dizziness was associated with higher odds of neck/shoulder pain (odds ratio = 1.9, 95% CI, 1.2-3.0; P = 0.004). No differences were observed between dizzy patients with and without neck/shoulder pain for near point of convergence (10.0 ± 7.5 vs 8.5 ± 6.7 cm, P = 0.43), modified Balance Error Scoring System (8.9 ± 5.5 vs 6.8 ± 4.7 errors, P = 0.09), or tandem gait (single-task: 26.0 ± 12.3 vs 24.2 ± 11.9 seconds, P = 0.56; dual-task: 35.1 ± 14.3 vs 35.6 ± 18.6 seconds, P = 0.90). In concussion patients experiencing dizziness, evaluating neck/shoulder pain may help identify individuals who would benefit from cervical spine rehabilitation. However, other potential causes of dizziness should also be evaluated to facilitate timely recovery.

Assessment of residual dizziness after successful canalith repositioning maneuvre in benign paroxysmal positional vertigo patients: a questionnaire-based study.

The purpose of this study was to assess residual dizziness (RD) after successful canalith repositioning maneuvre (CRM) treatment in patients with benign paroxysmal positional vertigo (BPPV) using Dizziness Handicap Inventory (DHI) questionnaire and Visual Analog Scale (VAS). One hundred sixty BPPV patients after successful CRM treatment were recruited. All patients were divided into the residual dizziness (RD) group and without RD group. The DHI questionnaire and VAS before CRM and follow-up were asked to complete. For analysis of the improvement in symptom, we defined ∆DHI and ∆VAS as the difference between the baseline score and the follow-up score. High incidence of RD was observed in the older patients (p < 0.001). The incidence of hypertension in the RD group was also significantly higher than that of the without RD group (p = 0.022). The ∆DHI-P, ∆DHI-E, ∆DHI-F, ∆DHI-T, and ∆VAS scores in the without RD group were significantly higher than that of the RD group (p < 0.001). When the cutoff point of the ∆DHI total scores was 17, the sensitivity was 64.86% and the specificity was 73.26% for diagnosing RD. When the cutoff point of the ∆VAS scores was 2.5, the sensitivity was 77.03% and the specificity was 81.40% for diagnosing RD. RD is prone to occur in the older patients and ∆VAS exhibits higher sensitivity and specificity in assessing RD.

The clinical application of head-shaking test combined with head-shaking tilt suppression test in distinguishing between peripheral and central vertigo at bedside vs. examination room

ObjectivesTo investigate the clinical value of using Head-Shaking Test (HST)+Head-Shaking Tilt Suppression Test (HSTST) to distinguish between peripheral and central vertigo as well as to analyze the consistency of findings between tests at the bedside vs. in the examination room. MethodsWe retrospectively analyzed patients who presented for central or peripheral vertigo from July 2019 to July 2021. The results were compared between HST and HST+HSTST. The concordance between bedside and examination room outcomes was analyzed. ResultsForty-seven (58.8%) patients in the peripheral vertigo group and 33 (41.2%) patients in the central vertigo group were included. In the peripheral group, 44 (both examination room and bedside: 93.6%) patients had horizontal Head-Shaking Nystagmus (hHSN), most of which were suppressed in HSTST. However, in the central group, most cases had perverted HSN (pHSN; examination room: 72.7%; bedside: 66.7%), which was seldomly suppressed in HSTST. The HST+HSTST showed a >20% higher specificity in identifying peripheral vertigo than HST alone. The bedside results were consistent with the examination room results using the kappa test (p<0.001). ConclusionsSuppressed hHSN was a strong indicator of peripheral vertigo. Conversely, pHSN was more often seen in central vertigo, which was not readily suppressed in HSTST. The bedside results of HST+HSTST yielded qualitative agreement with the tests in the examination room. HST+HSTST could be used as reliable methods in the clinic to distinguish between peripheral and central vestibular disorders. Level of evidenceLevel 3.
