PURPOSE OF REVIEW
The objective of this study was to explore the clinical spectrum of movement disorders and associated neurologic findings in hypomagnesemia and challenges in diagnosis and treatment.
RECENT FINDINGS
Sixty patients were identified in the literature for analysis. Movement disorders observed were postural tremor (23.3%, n = 14), resting tremor (8.3%, n = 5), intention tremor (10%, n = 6), ataxia involving the trunk (48.3%, n = 29) or limbs (25%, n = 15) and dysarthria (21.7%, n = 13), athetosis (8.3%, n = 5), myoclonus (6.7%, n = 4), and chorea (1.8%, n = 1). Symptoms may be accompanied by downbeat nystagmus, tetany, drowsiness, vertigo, and proximal muscle weakness. Residual deficits were noted in 16 (26.67%) patients. Serum magnesium was 1.3 mg/dL or lower in 53 patients (88.3%). Imaging findings include bilateral cerebellar (20%, n = 11) and vermis hyperintensities (9.09%, n = 5) and normal imaging. Proton pump inhibitors are the commonest etiology.
SUMMARY
The movement disorders linked with hypomagnesemia can be associated with varied neurologic symptoms. A high degree of suspicion will enable early diagnosis to prevent residual deficits.

Meta-Analysis Review
BACKGROUND
This meta-analysis provides a quantitative measure of the otorhinolaryngological manifestations of coronavirus disease 2019 in children.
METHODS
A structured literature review was carried out using PubMed, Embase and Cochrane Central, employing pertinent search terms. The statistical analysis was performed using Stata version 14.2 software, and the analysed data were expressed as the pooled prevalence of the symptoms with 95 per cent confidence intervals.
RESULTS
The commonest symptoms noted were cough (38 per cent (95 per cent confidence interval = 33-42; I = 97.5 per cent)), sore throat (12 per cent (95 per cent confidence interval =10-14; I = 93.7 per cent)), and nasal discharge (15 per cent (95 per cent confidence interval = 12-19; I = 96.9 per cent)). Anosmia and taste disturbances showed a pooled prevalence of 8 per cent each. Hearing loss, vertigo and hoarseness were rarely reported.
CONCLUSION
Cough, sore throat and nasal discharge were the commonest otorhinolaryngological symptoms in paediatric patients with coronavirus disease 2019. Compared with adults, anosmia and taste disturbances were infrequently reported in children.

Review
Scuba diving is a popular recreational and professional activity with inherent risks. Complications related to barotrauma and decompression illness can pose significant morbidity to a diver's hearing and balance systems. The majority of dive-related injuries affect the head and neck, particularly the outer, middle and inner ear. Given the high incidence of otologic complications from diving, an evidence-based approach to the diagnosis and treatment of otic pathology is a necessity. We performed a systematic and comprehensive literature review including the pathophysiology, diagnosis, and treatment of otologic pathology related to diving. This included inner, middle, and outer ear anatomic subsites, as well as facial nerve complications, mal de debarquement syndrome, sea sickness and fitness to dive recommendations following otologic surgery. Sixty-two papers on diving and otologic pathology were included in the final analysis. We created a set of succinct evidence-based recommendations on each topic that should inform clinical decisions by otolaryngologists, dive medicine specialists and primary care providers when faced with diving-related patient pathology.

INTRODUCTION
After more than a year of the COVID-19 pandemic, audio-vestibular problems have been reported as consequences. Several limited case report studies with different methodologies were published. This study aimed to describe the impact of COVID-19 on the auditory-vestibular system and communication problems in subjects with hearing impairment.
MATERIALS AND METHODS
The current systematic review was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline. PubMed, Web of Science, and Google Scholar were searched to find relevant articles using combined keywords.
RESULTS
Out of 26 final studies, 20 studies dealt with the effects of COVID-19 on the auditory and vestibular system, and six articles examined the COVID-19 effects on hearing-impaired people and patients. In these studies, dizziness (17.8%), tinnitus (8.1%), and vertigo (2.8%) were common symptoms. Most studies were case reports (42.30%), and in terms of quality, nine studies (34.61%) were in the suitable quality group.
CONCLUSIONS
COVID-19 might cause auditory-vestibular system problems by directly affecting the structures or functions of the inner ear or by weakening the immune system. The need for taking preventive measures during the COVID-19 pandemic has caused communication and social challenges, particularly for people with hearing loss.

Meta-Analysis
OBJECTIVE
To assess the proportion of individuals who report dizziness and/or vertigo during the prodromal phase or headache phase of migraine.
METHODS
The databases of MEDLINE and EMBASE were searched for studies on dizziness and/or vertigo during the prodromal phase or headache phase of migraine. Pooled relative frequencies were estimated using a random-effects meta-analysis.
RESULTS
We identified nine articles eligible for inclusion. Of these, one study reported results for the prodromal phase, seven studies for the headache phase and one study for both the prodromal and headache phase. In the prodromal phase, 9.0% of individuals with migraine reported dizziness, while 3.3% reported vertigo. During the headache phase, relative frequency of dizziness ranged from 6.7% to 59.6%, while vertigo ranged from 6.4% to 44.7%. The meta-analysis showed a relative frequency of 35.7% for dizziness (95% CI = 13.7-61.5%, I = 99%) and 33.9% for vertigo (95% CI = 26.7-41.5%, I = 87%). Study quality was rated 5/9 or below for seven studies and 6/9 or above for two studies.
CONCLUSION
We found that there is a scarcity of literature on dizziness and vertigo as prodromal- and headache-associated symptoms in individuals with migraine. Methodological variations confound comparisons of epidemiological patterns, although it appears that dizziness and vertigo are more frequent during the headache phase of migraine, compared with the prodromal phase. Future studies should ensure use of standardized definitions and rigorous methodology to enable accurate measurements of dizziness and vertigo in migraine.

Review
BACKGROUND
Vertigo is a cardinal symptom of posterior circulation infarction (POCI). Acupuncture is demonstrated to have a beneficial effect on posterior circulation infarction vertigo (PCIV). However, the mechanism of acupuncture therapy is not clarified. This study aims to assess the cerebral blood flow velocity modulation and clinical efficacy of acupuncture for PCIV patients.
METHODS
We conducted this systematic review for clinical randomized controlled trials (RCTs) regarding acupuncture on PCIV. The study duration was from September 2020 to September 2021. We searched the PubMed, EMBASE, Cochrane Library, Web of Science, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database, and VIP. The publication date was set from inception to August 31, 2020. Based on the inclusion and exclusion criteria, two researchers independently screened literature and extracted data including basic study information, intervention details, outcome details, and adverse events. Outcome measures included the blood flow velocities of vertebrobasilar arteries and the Clinical Effective Rate of posterior circulation infarction vertigo. Pooled data were presented as standardized mean differences (SMDs) and relative risks (RR), with 95% confidence intervals (CIs). The meta-analysis was conducted using Review Manager software version 5.3.0.
RESULTS
A total of 20 eligible RCTs (1541 participants) were included in this review, which compared acupuncture therapy (1 RCT) or acupuncture combined with pharmaceutical therapy (19 RCTs) to pharmaceutical therapy in patients with posterior circulation infarction vertigo. 7 studies assessed the blood flow velocities of the basilar artery examined by Transcranial Doppler (TCD), 8 studies assessed the bilateral vertebral arteries, and 13 studies evaluated the Clinical Effective Rate of posterior circulation infarction vertigo. Meta-analysis results showed that blood flow velocities of the basilar artery (SMD = 0.58, 95% CI = 0.40-0.76; < 0.05), left vertebral artery (SMD = 0.48, 95% CI = 0.22-0.73; < 0.05), and right vertebral artery (SMD = 0.44, 95% CI = 0.19-0.69; < 0.05) were significantly higher in the acupuncture group compared with the control group. Clinical Effective Rate (RR = 1.22, 95% CI = 1.15-1.29; = 0.792) was significantly better in the acupuncture group compared with the control group.
CONCLUSIONS
This study shows that acupuncture therapy is useful in improving the blood flow velocity of vertebrobasilar arteries and Clinical Effective Rate in patients with posterior circulation infarction vertigo. However, double-blind, sham-controlled trials with large sample sizes are required to support our conclusions.

Review
Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, and it is characterized by episodes of vertigo roundabout when the head is moved. A systematic review was performed using the most important scientific databases. This review included studies published in English in the last ten years, performed in adults, with emphasis on the diagnosis and treatment of BPPV. To investigate the long-term effectiveness of vestibular rehabilitation (VR) in patients with BPPV and the rate of recurrence of symptoms. A total of 38 studies were identified, of which only 12 met the inclusion criteria. The majority of the studies stated that VR is effective in decreasing the symptoms, with a short-term efficacy of 84.7%, and 89.2% in the long term in the reviewed studies. Valuable studies show the beneficial effects of the maneuvers for the treatment of BPPV and their long-term effectiveness. This strengthens the conclusion that this treatment is effective in resolving symptoms and decreasing recurrences.

Meta-Analysis
BACKGROUND AND PURPOSE
Cervical vertigo (CV), one of the most common causes of vertigo, makes patients feel dizzy, which seriously affects patients' lives. As a traditional Chinese bone-setting manipulation, Tuina is widely used to treat CV. This article aims to evaluate the effectiveness and safety of Tuina for CV.
METHODS
Nine databases were searched. Methodological quality was evaluated with the Cochrane Collaboration's tool. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was applied to determine confidence in the effect estimates. Stata 12.0 software was used to carry out the meta-analysis, and a trial sequential analysis (TSA) was performed with TSA 0.9.
RESULTS
Nine randomized controlled trials (RCTs) were included. Low-quality evidence suggested that Tuina showed a significantly higher effectiveness rate compared to massage therapy (risk ratio (RR) = 1.11, 95% confidence intervals (CI): 1.05 to 1.17, p < 0.0001) and cervical traction (RR = 1.37, 95% CI: 1.09 to 1.72, p = 0.007; I = 0%, p = 0.826). Two trials reported that Tuina was better than acupuncture (RR = 1.40, 95% CI: 1.07 to 1.83) or betahistine mesilate (RR = 1.17, 95% CI: 0.99 to 1.37) based on an improved effectiveness rate. Low-quality evidence showed that Tuina was superior to massage therapy in improving scores on the evaluation scale for cervical vertigo (ESCV) (weighted mean differences (WMD) = 2.52, 95% CI: 1.11 to 3.94, p < 0.0001). Adverse events were tolerable. TSA revealed that an improved effectiveness rate was indicated.
CONCLUSION
Tuina might improve the effectiveness rate and ESCV scores in patients with CV. However, the level of all the available evidence was low, and larger-scale and well-designed RCTs should be encouraged.

Review
INTRODUCTION
Menière's disease causes recurrent vertigo, hearing loss, tinnitus, and fullness or pressure in the ear, which mainly affects adults aged 40-60 years. Menière's disease is at first progressive but fluctuating, and episodes can occur in clusters. Vertigo usually resolves but hearing deteriorates, and symptoms other than hearing loss and tinnitus usually improve regardless of treatment.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for acute attacks of Menière's disease; and of interventions to prevent attacks and delay disease progression of Menière's disease? We searched: Medline, Embase, The Cochrane Library and other important databases up to January 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 17 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: anticholinergics, benzodiazepines, betahistine, cinnarizine, dietary modification, diuretics, phenothiazines, psychological support, trimetazidine, vestibular rehabilitation.

Review
OBJECTIVE
Sporadic unilateral vestibular schwannomas are rare in the pediatric population. Little has been reported in the literature on the presentation, tumor size, response to surgical treatment, and recurrence rates in these younger patients. The authors' goal was to describe their institutional experience with pediatric sporadic vestibular schwannomas and to conduct a meta-analysis of the existing literature to provide further insight into the presentation, tumor characteristics, and surgical outcomes for these rare tumors to help direct future treatment strategies.
METHODS
The authors performed a retrospective review of all patients 21 years of age or younger with unilateral vestibular schwannomas and without neurofibromatosis type 2 who underwent resection by the senior authors between 1997 and 2019. A systematic review of the literature and meta-analysis was also performed by entering the search terms "pediatric" and "vestibular schwannoma" or "acoustic neuroma," as well as "sporadic" into PubMed. Presentation, treatment, clinical outcomes, and follow-up were analyzed.
RESULTS
Fifteen patients were identified at the authors' institution, ranging in age from 12 to 21 years (mean 16.5 years). Common presenting symptoms included hearing loss (87%), headache (40%), vertigo (33%), ataxia (33%), and tinnitus (33%). At the time of surgery, the mean tumor size was 3.4 cm, with four 1-cm tumors. Four patients had residual tumor following their first surgery, 3 (75%) of whom had significant radiographic regrowth that required further treatment. The literature review identified an additional 81 patients from 26 studies with patient-specific clinical data available for analysis. This resulted in a total of 96 reported patients with an overall average age at diagnosis of 12.1 years (range 6-21 years) and an average tumor size of 4.1 cm.
CONCLUSIONS
Pediatric vestibular schwannomas present similarly to those in adults, although symptoms of mass effect are more common, as these tumors tend to be larger at diagnosis. Some children are found to have small tumors and can be successfully treated surgically. Residual tumors in pediatric patients were found to have a higher rate of regrowth than those in their adult counterparts.
