He Y, Kuai NS, Deng LM, Wang ZL, Peng MJ. An investigation into accidents in laboratories in universities in China caused by human error: A study based on improved CREAM and SPAR-H. Heliyon 2024; 10:e28897. [PMID: 38596102 PMCID: PMC11002268 DOI: 10.1016/j.heliyon.2024.e28897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 03/07/2024] [Accepted: 03/26/2024] [Indexed: 04/11/2024] Open
Abstract
Although considerable research has been devoted to improving safety in university laboratories, accidents, in that environment, have still occurred frequently at the cost of serious injury or even death of laboratory personnel. Currently, few Human Reliability Analyses (HRA) have been conducted with respect to a university laboratory. The aim of the research was to conduct a reliability study relating to human behaviour in a university laboratory to explore quantitatively the causes and influencing factors relating to the frequency of laboratory accidents. Improved Cognitive Reliability and Error Analysis Method (CREAM) and improved Standardized Plant Analysis Risk HRA (SPAR-H) were employed to assess Human Error Probability (HEP) of 23 subjects. The HEP calculated through improved CREAM proved more accurate than results obtained through improved SPAR-H. Unexpectedly, the results demonstrated that under similar environmental conditions, the HEP of subjects did not decrease with an increase in educational background, including additional experimental time and experience. Moreover, environmental conditions exerted greater impact on personnel reliability than Human Inherent Factors (HIFs) in laboratories. It is anticipated that the study would provide valuable insights, in respect of research methods, and to serve as a practical basis for lowering the accident rate in university laboratories.

[PMID: 34750034 PMCID: PMC9068827 DOI: 10.1016/j.jvoice.2021.09.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 09/19/2021] [Accepted: 09/21/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Voice disorders are a common communication disorder in children. Behavioral voice therapy is recommended by both Otolaryngologists and Speech-Language Pathologists as a first-line approach for treatment of benign vocal fold lesions that affect children in large numbers. However, the role of cognitive mechanisms critical to voice therapy have not yet been explored. OBJECTIVE This proof-of-concept study aims to provide preliminary data on the potential relation between cognitive abilities and behavioral results of voice therapy for children with benign phonotraumatic vocal fold lesions. METHODS Six children (4;05 -9;02 years) diagnosed with vocal fold nodules completed a battery of cognitive tests from the NEuroPSYchological (NEPSY-II) Assessment and a standard course of "Adventures in Voice" therapy. Recordings pre and post intervention were analyzed acoustically using the Cepstral Spectral Index of Dysphonia (CSID) and perceptually using visual analog scales (VAS) for severity and resonance separately. Raw and age-corrected scaled scores from the NEPSY-II were then examined for their possible relation to voice outcomes. RESULTS Multiple cognitive functions correlated with voice outcomes. Raw score measures for Design Fluency, Inhibition, Fingertip Tapping, and Narrative Memory correlated favorably with all voice outcome measures. Age correlated with all NEPSY-II raw scores and perceptual voice outcome measures. Scaled scores for Auditory Attention, Design Fluency, Fingertip Tapping (Dominant hand), and Narrative Memory correlated with all voice outcome measures. CONCLUSION Results suggest that there is merit to further investigation of the relation between cognitive skills and their development and voice treatment outcomes in children with benign phonotraumatic lesions. Future studies with larger samples will build on present findings.

PLoS One 2023; 18:e0288252. [PMID: 37922255 PMCID: PMC10624316 DOI: 10.1371/journal.pone.0288252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/22/2023] [Indexed: 11/05/2023] Open
Abstract
In this study, we aim to evaluate the efficacy and safety of acupuncture for vocal nodules, concerning qualitive overall efficacy and quantitative improvement on quality of voice. Four English and four Chinese databases were searched up to December 10th, 2022. Risk of bias among the included trials were evaluated by the Cochrane ROB tool. Systematic reviews and meta-analyses were conducted based on the Cochrane systematic review method by using RevMan 5.4 Software, and trial sequential analyses were performed by TSA 0.9. Meta-influence analyses, subgroup-analyses, meta-regression, and evaluation of publication bias were performed for exploration of heterogeneity by Stata V.14. Quality of the results was accessed through the GRADE-pro GDT. Cluster analyses and correlation coefficient were performed by R 4.1.3. Finally, 15 trials involving 1,888 participants were included. Results showed that compared with western medicine alone or Chinese herbal medicine alone, acupuncture alone yielded significantly (p<0.05) higher clinical effective rate and more improvement on scores of voice analyses. However, reduction on scores of grade, roughness, and breathiness and voice handicap index during follow-ups, and results of clinical effective rate suggested that acupuncture was inferior to voice training. In addition, meta-regression and sub-group analyses firstly revealed advanced efficacies of acupuncture when performed with local and remote acupoints, compared with local acupoints only. Acupuncture specified adverse event was denied in six trials while it was not mentioned in other nine trials. Results of cluster analyses and correlation coefficient showed that Kai yin yi hao and He gu (LI-4) were the most frequently applied matching-acupoints in trials. In conclusion, compared with western medicine (level of evidence: low ⨁⨁◯◯, GRADE C) and Chinese herbal medicine (level of evidence: moderate ⨁⨁⨁◯, GRADE B), acupuncture is safe and of better efficacy for patients with vocal nodules, while there is also need for RCTs with improvements on designing and interventions in experimental and controls.

Abstract
To determine the prevalence of laryngeal pathology in children presenting with cleft palate with or without cleft lip (CP ± L) who underwent nasoendoscopy to assess palatal function. A secondary aim was to determine the relationship between patient demographics, resonance, articulation, and prevalence of laryngeal pathology in this population. Retrospective, observational cohort study. Outpatient pediatric cranio-facial anomalies clinic. Children ≤18 years of age presenting with CP ± L (N = 215) who underwent nasoendoscopy, speech language pathology, plastic surgery, and otolaryngological evaluations between 2009 and 2020. Laryngeal diagnosis by pediatric otolaryngologists. 21.9% of children presented with laryngeal pathology. Diagnoses included benign vocal fold lesions and laryngeal edema sufficiently severe to alter vocal fold edge contour. Likelihood of laryngeal pathology increased by approximately 12% with every increase of 1 year in age (P = .001, OR = 1.12). Children with laryngeal pathology were 50% more likely to have undergone palatal repair (P < .001, OR = 1.50). In addition, children with severely hypernasal resonance were 78% less likely to present with laryngeal pathology (P =.046, OR = 0.22). This population is at increased risk for laryngeal pathologies as determined by nasoendoscopy. This finding underscores the importance of careful laryngeal imaging in assessing these children. Additional research is warranted to identify the mechanisms underlying the increased risk for morphological vocal fold changes.

Abstract
The main causes of voice disorders in children with adverse vocal behavior include benign lesions of the vocal folds caused by voice abuse or misuses, such as vocal fold nodules, vocal fold polyps, and laryngitis. Long-term voice disorders can affect the physical and mental health of children. Reviewing the literature of the last two decades on "Vocal Fold Nodules," "Vocal Fold Polyp," "Voice disorder," "Voice Abuse," "Voice Misuse," "Pediatrics," and "Children" with the appropriate Boolean operators. Conclusion: A total of 315 results were returned on an initial PubMed search. All articles from 2000 to 2022 written in English or Chinese were screened. Duplicate articles, those relating to adults only or concerned with the malignant lesion of the vocal cord, were excluded, resulting in 196 articles of interest. Relevant references and books have also been consulted, and we provide a review of the pathogenesis, diagnosis, and treatment of these maladaptive vocal behavioral voice disorders. What is Known: • Hoarseness is the most common voice symptom in children, and there are various causes of hoarseness in children. However, there is a lack of reviews on voice disorders caused by adverse vocal habits in children. • Voice training is a conservative treatment method for children with voice disorders , and it is important to clarify the factors that influence the effectiveness of voice training for children. What is New: • This review of the personality and family characteristics of children with adverse vocal behavioural voice disorders provides a valuable guide to the clinical planning of subsequent treatment. • This article discusses and summarises some of the factors that may influence the effectiveness of voice training in children and collates some of the scales and questionnaires currently used in children that are important in predicting the effectiveness of voice training.

Abstract
INTRODUCTION Vocal fold nodules (VNs) in children are benign, bilateral, callous-like lesions at the junction of the anterior third and posterior two-thirds of the true vocal folds. Chronic, repetitive, and intense vocal behavior is often cited as the primary etiology; however, difficulties with emotional adjustment may predispose some children towards extreme and possibly phonotraumatic vocal activity, thereby contributing secondarily to the development of VNs. OBJECTIVES This case-control study examined the association between features of emotional adjustment and VNs in children. METHODS Parents of children with VNs (N = 40, Mage = 7.5, SDage = 2.03) and two medical control groups [ie, voice disordered, but not VNs (VDCs; N = 40, Mage= 7.09, SDage = 2.01) and vocally normal controls (VNCs; N = 40, Mage = 7.6, SDage = 1.54)] participated in the study. Features of emotional adjustment were assessed using two inventories: the Parent Rating scale for Reactive and Proactive Aggression and the Revised Child Anxiety and Depression Scale - Parent version. RESULTS As compared with the VNCs, children with VNs were significantly more aggressive (P = 0.042, Cohen's d = 0.47) whereas the VDCs were more depressed (P = 0.013, Cohen's d = 0.60). Furthermore, VDCs experienced more separation anxiety than VNs (P = 0.038, Cohen's d = 0.45) and VNCs (P = 0.021, Cohen's d = 0.55). No other significant between-group differences were identified between the VNs and VDCs. CONCLUSIONS When present, elevated aggression may represent a risk factor for VNs formation in children, and possibly influence treatment outcomes. Therefore, the current results highlight the importance of understanding the role of emotional adjustment in the evaluation and treatment of dysphonia in children.

Abstract
INTRODUCTION Vocal fold nodules (VNs) represent the most common cause of voice disorders in children. Phonotrauma related to chronic, repetitive, intense vocal activity is often cited as the proximate cause of VNs. However, diminished self-regulation (SR) may predispose some children toward extreme phonotraumatic voice use, thereby contributing secondarily to their development. This case-control study examined the association between features of SR and VNs in children. METHOD Parents of children with VNs (N = 40, Age Mean = 7.5, SD = 2.03 years) and vocally normal, medical controls (VNCs; N = 40, Age Mean = 7.6, SD = 1.54 years) completed the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2; Gioia, Isquith, Guy & Kenworthy, 2015), an inventory that evaluates components of SR in children. RESULTS Children with VNs, as compared with the vocally normal control group, were described as (i) impulsive (i.e., scoring significantly worse on the Behavior Regulation Index, BRI; P < 0.001, Cohen's d = 0.86), and (ii) emotionally dysregulated (i.e., scoring significantly worse on the Emotional Regulation Index, ERI; P < 0.001, Cohen's d = 0.81). CONCLUSIONS Diminished SR in some children with VNs may contribute to phonotraumatic vocal behaviors and potentially attenuate the effectiveness of voice therapy.

Abstract
Abstract
Objective
To determine the demographic, aetiopathological and diagnostic profiles of patients presenting with hoarseness to a laryngology unit of a tertiary care centre in India.
Methods
A retrospective observational study was conducted.
Results
The 1033 patients who presented with dysphonia showed a male predominance (70 per cent), high rates of malignancy (18 per cent), late presentation (mean, 24 months) and poor follow-up trends (53 per cent with 3 months’ follow up), which contrasts with data from developed countries. The patient population hailed from different states in India and neighbouring countries around India, serving as a good sample for the subcontinent. The majority (67 per cent) were managed conservatively; however, surgical management was the preferred choice for those who presented with airway stenosis (91 per cent) and laryngeal trauma (75 per cent). Significant associations between vocal professionalism level and co-morbidities and dysphonia aetiopathologies are discussed.
Conclusion
These findings give insight into the trends of hoarseness in the developing Indian subcontinent, which can aid understanding and management.

Abstract
Purpose Vocal fold nodules (VNs) are bilateral, symmetrical, callous-like lesions secondary to phonotrauma and possibly related to specific personality traits. This case-control study examined the relation between personality and VNs in children within the context of the Trait Theory of VNs. Method Parents of children with VNs (N = 39, M = 7.43, SD = 2.01 years) and two medical control groups (i.e., voice disordered controls, but not VNs [VDCs; N = 40, M = 7.09, SD = 2.01 years] and vocally normal controls [VNCs; N = 40, M = 7.6, SD = 1.54 years]) completed the Inventory of Child Individual Differences, a personality instrument that describes the Big Five superfactors as well as 15 lower order personality traits. Results Children with VNs, as compared with VNCs, were (a) emotionally reactive (i.e., higher N-Neuroticism, p < .005, Cohen's d = 0.53), (b) Antagonistic, Strong-Willed, and less Compliant (i.e., lower A-Agreeableness, p < .014, Cohen's d = 0.59), and (c) Distractible and Disorganized (i.e., lower C-Conscientiousness, p < .009, Cohen's d = 0.62). Both voice disordered groups displayed elevated scores on the personality superfactor of Neuroticism (N; and the "Negative Emotions" lower order trait). Conclusions The combination of personality traits identified in this study (i.e., high N, low A and C) may play a central role in VNs development and possibly attenuate voice therapy success. Children with VNs displayed a similar personality typology as women with VNs, with the exception of elevated Extraversion (E), thereby providing support for the relevance of the Trait Theory of VNs in both children and adults. Clinicians treating children with voice disorders, including VNs, should consider their underlying personality traits in assessment and management.

Abstract
Vocal pitch discrimination abilities were compared in sixteen children with vocal fold nodules (CwVN) and sixteen matched controls with typical voices (CwTV). Vocal pitch discrimination was also evaluated in thirty-five vocally healthy children and twenty adults to examine potential changes as a function of maturation. CwTV were categorized as either younger (N = 15, 5.6-7.7 years) or older (N = 20, 8.2-11.7 years). Participants completed two-alternative, forced choice listening tasks in which they judged whether pairs of sustained /α/ tokens were different in pitch. Each pair consisted of a base token with a fundamental frequency fo ) of 216.2 Hz and a test token with a fo that was adaptively modified, according to the participant's prior judgments. There were no significant differences in pitch discrimination abilities between CwVN and CwTV. Pitch discrimination abilities were significantly poorer in younger and older CwTV as compared to adults. Additionally, younger CwTV had significantly poorer discrimination abilities than older CwTV. Findings from this study suggest that CwVN do not have differences in pitch discrimination abilities, yet, therapies designed for CwVN should consider this developmental trend in perceptual abilities.

Abstract
PURPOSE Vocal fold nodules are usually caused by voice overuse or vocal hyperfunction, and their symptoms include persistent hoarseness - a disturbance in the vocal fold vibrations which results in a turbulent passage of air in the glottis, manifested as a raspy, rough voice. The aim of the study was to present data concerning voice quality in patients with vocal nodules and to compare electroglottographic analysis (EGG) with acoustic analysis. METHODS The study examined 57 children with vocal fold nodules (Group 1). Each patient underwent a phoniatric evaluation of the vocal tract, a videolaryngoscopic examination, and a voice quality assessment, employing electroglottographic and acoustic analyses. The control group consisted of 37 healthy children (Group 2). The following parameters were analyzed: Closed Quotient (EGG signal), Peak Slope, Normalized Amplitude Quotient and Cepstral Peak Prominence (acoustic signal - waveform). RESULTS Changes in the EGG signal could be detected in 95% of the patients with vocal nodules, indicating the occurrence of vocal nodules and glottal insufficiency. The acoustic analysis confirmed breathy phonation in 63% of the patients. The Closed Quotient parameter proved to be more effective than Peak Slope. Closed Quotient, Peak Slope and Normalized Amplitude Quotient allowed for the differentiation of the EGG signal and the acoustic signal in groups 1 and 2 in a statistically significant way. CONCLUSIONS The results of electroglottographic and acoustic analysis show incorrect voice parameters in patients with vocal nodules with reference to the control group. At the same time, the EGG analysis proved to be more effective than the analysis of the acoustic signal.
