Modification of McGill Oximetry Score in Improving the Diagnostic Capability of Paediatric OSA.

OBJECTIVES: This study aimed to devise a modified oximetry scoring system and calculate its diagnostic accuracy in detecting paediatric obstructive sleep apnoea syndrome (OSAS). STUDY DESIGN: This prospective diagnostic accuracy study was divided into two phases. SETTING: The study was conducted at a quaternary teaching hospital. METHODS: Polysomnograms performed from 1 April 2014 to 31 December 2021 were included. In Phase 1, the parameters of 95 oximetry trend graphs were evaluated, and a modified scoring system was constructed. In Phase 2, the modified scoring system was employed in 272 oximetry trend graphs, and its diagnostic accuracy was determined. A logistic regression model was used to assess the ability of each scoring system to predict paediatric OSAS. RESULTS: A total of 367 patients were recruited. In Phase 1, a four-tier severity classification system was constructed. In Phase 2, its diagnostic accuracy was found to be 53.3% sensitive, 97% specific, with positive predictive value of 98.5% and negative predictive value of 34.6%. The lowest detectable apnoea-hypopnoea index (AHI) was 4.5. The inter-rater reliability calculated was 80%. Logistic regression was applied to assess associations of the modified McGill score (MMS) or McGill oximetry score (MOS) with OSAS. The area under the receiver operating characteristic curve was higher for the MMS than for MOS (0.78 [95% CI 0.73-0.84] vs. 0.59 [95% CI 0.51-0.66]). CONCLUSION: This study demonstrated that our modified scoring system had increased sensitivity at detecting OSAS at a much lower AHI and showed a much greater ability to predict paediatric OSAS.

The global prevalence of vestibular dysfunction in children and adolescents: a systematic review and meta-analysis.

BACKGROUND: Vestibular dysfunction has been extensively studied amongst the older population. Recently, conditions and management of vestibular dysfunction among children and adolescent has gained attention. Yet, a lack of awareness and expertise in managing children and adolescents with vestibular dysfunction has led to a delay in diagnosis as well as a trifling prevalence rate. AIM: To conduct a systematic review and meta-analyses to estimate the overall pooled prevalence of vestibular dysfunction in children and adolescents. METHODS: PubMed, Scopus, and Web of Science databases were searched to identify studies published until 29 April 2022. We used a random-effects model to estimate the pooled prevalence with 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistic and Cochran's Q test. The robustness of the pooled estimates was checked by different subgroups and sensitivity analyses. RESULTS: We identified 1811 studies, of which 39 studies (n = 323,663) were included in the meta-analysis. Overall, the pooled prevalence of children and adolescents with VD was 30.4% [95% CI 28.5-32.3%]. The age of the participants ranged from 1 to 19 years. Participants of the included 39 studies were from 15 countries. Among the studies, 34 were cross-sectional, and five were case-control designed. There were discrepancies found in the studies with objective (higher prevalence) versus subjective (lower prevalence) evaluations. CONCLUSION: The prevalence of VD among children and adolescents was found to be 30.4% based on high-quality evidence. Due to the subjective assessment of most studies pooled in the analysis, the results should be interpreted cautiously until future comparative studies with objective assessments are carried out.

Outcome of canalith repositioning manoeuvre in benign paroxysmal positional vertigo in children and adolescents: A systematic review.

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is a debilitating condition that has been significantly described in adults. Recent data points out that BPPV occurs in children as well. Canalith repositioning manoeuvre (CRM) has shown promising results amongst adult patients with BPPV. OBJECTIVE: We reviewed the literature to determine the outcome of CRM in children and adolescents with BPPV. METHODS: A literature search was conducted over 1 month (March 2022). The primary outcome was defined as the resolution of positional nystagmus and symptoms, and secondary outcomes were determined by the presence of recurrence and the number of attempts of CRM. RESULTS: Ten articles were selected based on our objective and selection criteria. A total of 242 patients were included, with a mean of 10.9 years. BPPV was diagnosed based on history and positional nystagmus in all patients (100%). CRM was performed in 97.9% of patients, whereby 80.5% recovered following a single attempt of CRM. Recurrence of symptoms was identified in 10% of patients with no reported major complications. CONCLUSION: CRM has demonstrated promising results in children and adolescents. The quality of evidence is limited until a better-quality study involving randomised controlled studies with a larger sample size is completed.

Role of Video Head Impulse Test to Assess Noise Exposure.

Noise exposure has been reported to exert numerous detrimental effects on the human population, although most research has centred around hearing damage. Vestibular and balance loss have been demonstrated among industrial workers, although reports on this are still scarce. Vestibular loss increases the risk of falls, especially among industrial workers who are at constant risk. Nonetheless, the ideal investigation tool to investigate vestibular function remains unknown. We aim to review the available literature to elucidate the effect of noise exposure on semicircular canals using a video head impulse test (vHIT). A literature search identified only three studies involving 137 patients (mean age: 44.4). Semicircular canal deficit was found in 50.4% of the included participants, with lateral canal predominantly affected (71%). We highlight the importance of assessing the effect of noise exposure on vestibular function, especially among those prone to occupation-related vestibular loss.

Outcome of kinesio taping in drooling children: A systematic review.

INTRODUCTION: Drooling is a troublesome condition, especially in children with neuromuscular and intellectual disability. Over the past decade, novel interventions have been trialled to alleviate drooling in the affected children. Kinesio tape (KT) application has shown promising results in controlling drooling in children. We reviewed the literature to determine the outcome of KT application in drooling children. METHODS: A literature search was conducted from January 1, 1990 to March 2024 by searching several databases over a 1-month period (April 2024) according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary outcome was defined as the success of the intervention determined by the improvement or resolution of symptoms, and the secondary outcome was determined by adjunct or repeated procedures and the presence of complications. RESULTS: Overall, 172 children from 10 studies were identified. All studies included are retrospective studies (Level III). This review included 172 children, with a mean age of 8.2 years (Male: 58.7 %). All included children had underlying comorbidities (100 %), with neurological disorders (77 %) being the most prevalent. KT application was performed predominantly over the orbicularis oris in 6 studies, 118 children[68.6 %], suprahyoid region in 3 studies, 45 children (26.2 %) and multiregion over the head and neck in 1 study of children (5.2 %). Drooling was assessed subjectively in all 100 % of children with objective measurement performed in 3 studies. KT was the only intervention in 40.7 % of the included children, whereas KT was performed in combination with oromotor therapy in 48 children, speech therapy in 44 children, and manipulation therapy in 10 children. All included children (100 %) reported improvement in drooling. No studies reported adverse reactions to KT application. CONCLUSIONS: KT application is a safe, effective alternative for drooling children. The effect of KT, however, may be temporary. The quality of the evidence is inadequate to recommend widespread use of the intervention until a better-quality study has been completed. Future randomised controlled studies with a large sample size are warranted to determine the efficacy of this intervention among children.

An Unusual Presentation of Midline Lethal Granuloma.

Extranodal natural killer T-cell lymphoma, nasal type (ENKTCL), is a rare form of non-Hodgkin lymphoma that is strongly related to Epstein-Barr Virus (EBV) infection and commonly presents as "midline lethal granuloma." Herein, we report a middle-aged lady who presented with a two-week history of fever, sore throat and constitutional symptoms. Intraoral examination revealed a lacerated soft palate with an ulcerated uvula. A diagnosis of ENKTCL was confirmed through deep biopsies under general anaesthesia supplemented with a positive serum EBV genome. Unfortunately, she succumbed due to disease progression with left frontal brain metastasis with concurrent pulmonary tuberculosis before treatment was completed. The recommended treatment is multimodality with L-asparaginase-containing regimes chemotherapy in an advanced stage, relapsed, or refractory ENKTCL for better outcomes. The quantification of circulating plasma EBV deoxyribonucleic acid (DNA) is helpful as the baseline of tumour load and a biomarker for monitoring treatment response and prognostication. We advocate repeated and deeper core tissue biopsies.

Cervical bronchogenic cyst in a toddler.

Bronchogenic cyst is a congenital abnormality arising from the tracheobronchial system. Localisation of such cysts in the head and neck region is rare. We report a girl in her early childhood with a painless enlarging right lateral neck mass diagnosed with a branchial cleft cyst based on clinical and radiological MRI findings. An incidental finding of a cervical bronchogenic cyst was made on the final histopathological specimen. Although rare, bronchogenic cysts should be considered as differential diagnoses for paediatric patients' lateral and midline cervical masses.

Vestibular Dysfunction Among Children with Otitis Media and Effusion in a Multiracial Setting.

Otitis media with effusion (OME) is a common presentation to the Otorhinolaryngology clinic. Besides hearing impairment, recent evidence shows that approximately 30% of these children have some degree of vestibular and balance impairment. To assess the presence of vestibular dysfunction among children with OME. Children between 4 and 17, with and without OME, underwent vestibular assessment using video head impulse test (VHIT), subjective visual subjective (SVV), and single leg raising test (SLS). Data were recorded and analysed. 24 OME children were included with male predominance. No statistical significance was found between the VOR gain (p > 0.05), SVV (p = 0.056) and SLS (p = 0.06). Simple linear regression analysis showed that age and gender are potential factors for VOR gain. Our study found that children with OME have normal vestibular function.

Familial congenital laryngotracheal stenosis: A systematic review.

BACKGROUND: Congenital laryngotracheal stenosis (CLS) is a rare cause of stridor among newborns. Evidence has shown that several family members can be affected by CLS. Knowledge of the pathophysiology of familial congenital laryngotracheal stenosis (FCLS) will enable more effective therapeutic strategies. OBJECTIVE: To determine the clinical course and outcome of familial congenital laryngotracheal stenosis (FCLS). METHODS: A literature search was conducted over a period of one month (September 2023) by searching several databases to identify studies published from inception to 31st August 2023. RESULTS: Of 256 papers identified, five articles met the inclusion criteria. A total of 17 patients with slight female predominance (59 %) were identified. Familial congenital tracheal stenosis was reported in female twins (100 %). A variety of clinical presentations were listed. An endoscopic airway study was performed on all patients. 64.8 % of the included children were managed surgically. Genetic studies performed on 41 % of children could not locate genetic abnormalities. CONCLUSION: Consanguinity, twin births, and female gender could be predisposing factors for FCLS, although the quality of evidence is low due to the rarity of the condition.

Experience from the First Paediatric Vestibular and Balance Clinic in a Multiracial Asian Setting.

Objective: Paediatric vestibular and balance services have recently gained attention across the globe. We present our one-year experience exploring the aetiology of paediatric vestibular disorders in a recently established Paediatric vestibular and balance clinic. Methods: Children and adolescents under 18 referred to the Paediatric Vestibular and Balance Clinic for evaluation were included. Results: 74 children were included in this study (Mean age: 10.04 ± 3.9). We found a slight female predominance, n = 38 (51.35%). Abnormal vestibular function was observed in 60.8% of children. Vestibular migraine (VM) was the most common aetiologic cause, n = 35 (47.3%), followed by vestibular/balance delay (n = 11). Conclusion: The most prevalent cause of dizziness was VM, followed by vestibular delay found in children with isolated speech and language delay. We highlight the importance of awareness of various causes of dizziness in children amongst carers and physicians to diagnose and manage it early.

Could Cultural and Background Resilience be the Main Culprit for Neglected Vestibular Dysfunction in Children?

Vestibular dysfunction in children and adolescents has recently gained tremendous attention, with more child-friendly investigations and rehabilitation protocols emerging.Reports have shown that children with vestibular impairment tend to develop speech and language acquisition delay, fine and gross motor delay, which in the long-termresults in an overall poor quality of life. In an extreme situation, vestibular dysfunction can lead to dissociative syndromes such as depersonalisation/derealisation symptomsthat occur following a mismatch between the vestibular signals and other sensory inputs, which may, in turn, lead to suicidal thoughts and behaviour 1. Whilst measuresto incorporate vestibular assessment as a part of routine practice in paediatric patients have been carried out in most centres, pediatric vestibular medicine appears to beunfathomed in some parts of the world, notably the South-East Asian region.

Vestibular migraine: a manifestation of long COVID syndrome in children.

Long COVID-19 syndrome has been reported among children and adolescents following COVID-19 recovery. Among them, notable symptoms include myalgia, insomnia, loss of smell and headache. Yet, novel manifestations are being discovered daily. Herein, we report two cases of vestibular migraine post-COVID-19 involving two children who presented with vestibular migraine symptoms following COVID-19 infection and their management. Children post-COVID-19 should be thoroughly evaluated for vestibular migraine symptoms so they can be managed promptly. This is the first article to report vestibular migraine as a manifestation of long COVID-19 syndrome.

The link between airway reflux and non-acid reflux in children: a review.

OBJECTIVE: Airway reflux, a member of extra-esophageal reflux, has been linked to countless respiratory pathologies amongst children. The advent of novel instrumentation has enabled the discovery of non-acid reflux which was postulated as the main culprit of airway reflux. The objective of this review is to outline the association between non-acid reflux and airway reflux in children. METHODS: A comprehensive review of recent literature on non-acid reflux and airway reflux in children was conducted. Studies ranged from January 2010 till November 2021 were searched over a period of a month: December 2021. RESULTS: A total of eleven studies were identified. All studies included in this review revealed a strong link between non-acid reflux and airway reflux in children. 6 of the included studies are prospective studies, 3 retrospective studies, 1 cross-section study, and type of study was not mentioned in 1 study. The most common reported respiratory manifestation of non-acid reflux in children was chronic cough (7 studies). Predominant non-acid reflux was noted in 4 studies. The total number of children in each study ranges from 21 to 150 patients. MII-pH study was carried out in all studies included as a diagnostic tool for reflux investigation. CONCLUSION: Non-acid reflux is the culprit behind airway reflux as well as other myriads of extra-esophageal manifestations in children. Multicentre international studies with a standardized protocol could improve scientific knowledge in managing non-acid reflux in airway reflux amongst children.
