"The genie is out of the bottle": a qualitative study on the impact of COVID-19 on continuing professional development.

BACKGROUND: The onset of the COVID-19 pandemic catalysed a monumental shift in the field of continuing professional development (CPD). Prior to this, the majority of CPD group-learning activities were offered in-person. However, the pandemic forced the field to quickly pivot towards more novel methods of learning and teaching in view of social distancing regulations. The purpose of this study was to obtain the perspectives of CPD leaders on the impact of the pandemic to elucidate trends, innovations, and potential future directions in the field. METHODS: Semi-structured interviews were conducted between April-September 2022 with 23 CPD leaders from Canada and the USA. Interviews were audio-recorded, transcribed, and de-identified. A thematic analysis approach was used to analyse the data and generate themes. RESULTS: Participants characterised COVID-19 as compelling widespread change in the field of CPD. From the interviews, researchers generated six themes pertaining to the impact of the pandemic on CPD: (1) necessity is the mother of innovation, (2) the paradox of flexibility and accessibility, (3) we're not going to unring the bell, (4) reimagining design and delivery, (5) creating an evaluative culture, and (6) a lifeline in times of turmoil. CONCLUSION: This qualitative study discusses the impact of the pandemic on the field of CPD and leaders' vision for the future. Despite innumerable challenges, the pandemic created opportunities to reform design and delivery. Our findings indicate a necessity to maintain an innovative culture to best support learners, to improve the healthcare system, and to prepare for future emergencies.

Evaluating the impact of continuing professional development courses on physician behavioral intention: a pre-post study with follow-up at six months.

BACKGROUND: Continuing professional development (CPD) for health professionals includes educational activities to maintain or improve skills. We evaluated the impact of a series of CPD courses by identifying factors influencing physicians' intention to adopt targeted behaviors and assessing self-reported behavior adoption six months later. METHODS: In this pre-post study, eligible participants attended at least one in-person course at the Fédération des Médecins Spécialistes du Québec annual meeting in November 2019. Before and afterwards, participants completed CPD-REACTION, a validated questionnaire based on Godin's integrated model for health professional behavior change that measures intention and psychosocial factors influencing intention. We used Wilcoxon signed-rank test to compare pre- and post-course intention scores and linear regression analyses to identify factors influencing intention. We also compared the post-course intention scores of participants reporting a behavior change six months later with the scores of those reporting no behavior change six months later. Qualitative data was collected only six months after courses and responses to open-ended questions were analyzed using the Theoretical Domains Framework. RESULTS: A total of 205/329 course attendees completed CPD-REACTION (response rate 62.3%). Among these participants, 158/329 (48%) completed the questionnaire before CPD courses, 129/329 (39.2%) only after courses and 47/329 (14.3%) at 6 months. Study population included 192 physicians of whom 78/192(40.6%) were female; 59/192(30.7%) were between 50 and 59 years old; and 72/192 (37.5%) were surgical specialist physicians. Mean intention scores before (n = 158) and after (n = 129) courses were 5.74(SD = 1.52) and 6.35(SD = 0.93) respectively. Differences in mean (DM) intention before and afterwards ranged from - 0.31(p = 0.17) to 2.25(p = 0.50). Multivariate analysis showed that beliefs about capabilities (ß = 0.15, p = 0.001), moral norm (ß = 0.75, p < 0.0001), and beliefs about consequences (ß = 0.11, p = 0.04) influenced post-course intention. Post-course intention was correlated with behavior six months later (DM = 0.63; p = 0.02). Qualitative analysis showed that facilitators to behavior adoption after six months were most often related to the TDF domains of beliefs about capabilities. Most frequent barriers to adoption related to lack of resources. CONCLUSIONS: Overall, scores for intention to adopt targeted behaviors increased after the courses. CPD providers could increase participants' intention by including interventions that emphasize beliefs about capabilities, moral norm and beliefs about consequences.

Airway ultrasound: Point of care in children-The time is now.

BACKGROUND: Point-of-care ultrasonography of the airway is becoming a first-line noninvasive adjunct assessment tool of the pediatric airway. It is defined as a focused and goal-directed portable ultrasonography brought to the patient and performed and interpreted on the spot by the provider. Successful use requires a thorough understanding of airway anatomy and ultrasound experience. AIMS: To outline the many benefits, and some limitations, of airway ultrasonography in the clinical and perioperative setting. MATERIALS AND METHODS: Expert review of the recent literature. RESULTS: Ultrasound assessment of the airway may provide the clinician with valuable information that is specific to the individual airway static and dynamic anatomy of the patient. Ultrasound can help identify vocal cord dysfunction and pathology, assess airway size, predict the appropriate diameter of endotracheal and tracheostomy tubes, differentiate tracheal from esophageal intubation, localize the cricothyroid membrane for emergency airway access and identify tracheal rings for US-guided tracheostomy. Ultrasonography is also a great tool for the intraoperative diagnosis of a pneumothorax, the visualization of the movement of the diaphragms, and quantifying the amount of gastric content. Ultrasonography signs, tips, and pearls that allow these diagnoses are highlighted. The major disadvantage of ultrasonography remains interobserver variability, and operator dependence, as it requires specific training and experience. CONCLUSION: Although it is not standard of care yet, there is significant potential for the integration of ultrasound technology into the routine care of the airway.

Diagnosis of Primary Ciliary Dyskinesia. An Official American Thoracic Society Clinical Practice Guideline.

BACKGROUND: This document presents the American Thoracic Society clinical practice guidelines for the diagnosis of primary ciliary dyskinesia (PCD). TARGET AUDIENCE: Clinicians investigating adult and pediatric patients for possible PCD. METHODS: Systematic reviews and, when appropriate, meta-analyses were conducted to summarize all available evidence pertinent to our clinical questions. Evidence was assessed using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach for diagnosis and discussed by a multidisciplinary panel with expertise in PCD. Predetermined conflict-of-interest management strategies were applied, and recommendations were formulated, written, and graded exclusively by the nonconflicted panelists. Three conflicted individuals were also prohibited from writing, editing, or providing feedback on the relevant sections of the manuscript. RESULTS: After considering diagnostic test accuracy, confidence in the estimates for each diagnostic test, relative importance of test results studied, desirable and undesirable direct consequences of each diagnostic test, downstream consequences of each diagnostic test result, patient values and preferences, costs, feasibility, acceptability, and implications for health equity, the panel made recommendations for or against the use of specific diagnostic tests as compared with using the current reference standard (transmission electron microscopy and/or genetic testing) for the diagnosis of PCD. CONCLUSIONS: The panel formulated and provided a rationale for the direction as well as for the strength of each recommendation to establish the diagnosis of PCD.

Sialendoscopy in treating pediatric salivary gland disorders: a systematic review.

OBJECTIVE: The primary aim of this study is to conduct a systematic review in order to evaluate the use of sialendoscopy in treating pediatric salivary gland disorders. METHODS: Eligible articles were identified through a comprehensive search of electronic databases. Using predefined inclusion criteria, published articles on sialendoscopy in children were selected and reviewed. RESULTS: 17 articles including 323 pediatric patients and 424 salivary glands managed by sialendoscopy were identified. The most common salivary gland disorder affected was the parotid (83% of cases), followed by the submandibular gland (16.5% of cases). Juvenile recurrent parotitis (68.9%) was the most frequent diagnosis followed by sialolithiasis (14.7%). The most common complication was ductal perforation. During a pooled mean follow-up time of 18.3 months, recurrences were reported in 14.5% of patients mostly in patients diagnosed with juvenile recurrent parotitis. CONCLUSION: Sialendoscopy is a minimally invasive diagnostic and therapeutic tool for inflammatory salivary gland disorders in pediatric patients. Based on the current review, sialendoscopy can be successfully implemented in cases of pediatric salivary gland disorders.

Platinum-induced ototoxicity: a review of prevailing ototoxicity criteria.

The antineoplastic agent's cisplatin and carboplatin are widely used as they are highly effective. Unfortunately, ototoxicity is a frequently encountered side effect of platinum-based chemotherapy. Clinically, patients generally develop a progressive, bilateral, and irreversible sensorineural hearing loss. With rising cancer survival rates, a greater proportion of patients are living with the side effects of their chemotherapy treatments. Consequently, the quality of life of cancer survivors has now become a major concern for clinicians. Various classification systems are currently available to grade side effects and provide a guideline for subsequent treatments. An extensive review of the literature revealed that a variety of criteria are used worldwide for grading platinum-induced hearing loss in children and adults, including the National Cancer Institute criteria, Brock's grading system, the American Speech-Hearing-Language Association criteria, the World Health Organization criteria, the Pediatric Oncology Group criteria, and the Muenster classification. Less commonly used criteria include the Chang classification, the Functional Hearing Loss scale, the HIT system (German Hirntumor study grading system), and most recently, the International Society of Pediatric Oncology Boston ototoxicity grading scale. The objective of this review is to evaluate the commonly used ototoxicity criteria and discuss their benefits and limitations.

The impact of erdosteine on cisplatin-induced ototoxicity: a proteomics approach.

Cisplatin is a commonly used chemotherapeutic agent and causes serious side effects, including progressive and irreversible hearing loss. No treatment is currently available for cisplatin-induced ototoxicity. We have previously demonstrated that erdosteine, a potent antioxidant, partially protected the cochlea against cisplatin toxicity in vivo. The aims of this study were to (1) evaluate the protein profiles of the cochlea following cisplatin administration and (2) evaluate the impact of erdosteine on the protein profile using a proteomics-based approach. Thirty Sprague-Dawley rats were injected intraperitoneally with saline (n = 10), cisplatin (n = 10) or with cisplatin and erdosteine (n = 10). The cisplatin dosage was 14 mg/kg and for erdosteine, 500 mg/kg. Following euthanasia, protein lysates were obtained from fresh-frozen cochleae and were processed for mass spectrometry and western blotting. We detected 445 proteins that exhibited a twofold change or greater in the cisplatin group as compared to the control group. Of these, 18 proteins showed a fourfold or greater change in expression associated with cisplatin administration, including ras-related protein Rab-2A, Rab-6A, cd81, ribosomal protein S5, and myelin basic protein, which were downregulated, while Ba1-647 and fibrinogen (alpha chain), amongst others, were upregulated. Co-administration of erdosteine revealed a reversal of these changes in the expression of ras-related protein Rab-2A, ribosomal protein S5, myelin basic protein, and fibrinogen (alpha chain); erdosteine also upregulated glutathione reductase. In this study, we identified various proteins that may play a role in cisplatin-induced ototoxicity. We also observed the changes resulting from co-treatment with an antioxidant.

Association of onabotulinum toxin A treatment with salivary pH and dental caries of neurologically impaired children with sialorrhea.

BACKGROUND: Sialorrhea is a common manifestation of several neurological disorders. The use of intraglandular onabotulinum toxin A (OBTXA) injection has been recognized to effectively treat sialorrhea. As OBTXA injection reduces salivary flow rate and alters salivary quality, its use may have a detrimental effect on oral health. AIM: To examine the effect of OBTXA injection on caries experience and salivary pH of neurologically impaired children with sialorrhea. DESIGN: Twenty-five children receiving OBTXA treatment and 25 control children were enrolled in the study. Whole saliva was collected to determine salivary pH. All participants underwent an interview on their dietary habits. Dental clinical examinations were carried out to evaluate caries experience and oral hygiene level. RESULTS: Overall, mean salivary pH value was significantly lower in the OBTXA group (6.92 ± 0.77) compared with the control group (7.36 ± 0.70). Caries activity was significantly higher in the OBTXA group (P = 0.01). The regression analyses showed a significant association between OBTXA treatment and salivary pH value (P = 0.03). Results from the logistic regression show that dental caries was significantly associated with OBTXA treatment (OR = 1.73, CI = 1.14-27.3). CONCLUSIONS: The study showed an intricate relationship between OBTXA treatment and oral findings. Hence, special dental care should be given to children receiving OBTXA treatment.

Quantifying the Ototoxicity of Mitomycin: Before versus after Myringotomy.

OBJECTIVES: Recent research has focused on mitomycin C (MMC) application as a means to circumvent complications that arise when using ventilation tubes during myringotomy. This study has two aims: (1) to synergize the current literature to create a standardized clinical approach for using MMC, and (2) to determine at which point during the myringotomy the application of MMC proves the safest (i.e., before or after incision). METHODS: We measured the auditory brainstem response (ABR) and distortion product otoacoustic emissions (DPOAE) in 9 female chinchillas to determine whether applying MMC before or after incision was also the safest. The tests were then repeated on days 3, 10 and 17. RESULTS: The change in the ABR thresholds from baseline was greater in the experimental than in the control group; however, after stratification, the 'after' group experienced a statistically significant change (19.38 ± 8.26) on day 17, whereas the 'before' group did not (2.00 ± 3.26; p = 0.003). No such changes were seen with DPOAE testing. CONCLUSIONS: Mitomycin is less ototoxic to the middle ear when applied before myringotomy is done. We recommend future studies to apply the clinical approach we have designed to standardize its use in selected cases.

Incidence of platinum-induced ototoxicity in pediatric patients in Quebec.

BACKGROUND: The antineoplastic agents cisplatin and carboplatin are widely-used and highly-effective against a variety of pediatric cancers. Unfortunately, ototoxicity is a frequently encountered side effect of platinum-based chemotherapy. There is currently no treatment or prevention for platinum-induced ototoxicity and development of hearing loss may lead to devastating consequences on the quality of life of pediatric cancer survivors. The objective of this study is to determine the incidence of platinum-induced ototoxicity in a large series of pediatric patients and to evaluate the incidence of progression of ototoxicity after completion of treatment. PROCEDURES: A retrospective chart review of pediatric patients treated with cisplatin or carboplatin between 2000 and 2012 was conducted. The incidence of ototoxicity was determined based on the American-Speech-Language-Hearing Association (ASHA) criteria and severity was based on the Chang classification. RESULTS: Four hundred and sixty-six patients received platinum-based chemotherapy. Patients were excluded due to congenital hearing loss (n = 1) and insufficient data for calculating the platinum dose (n = 24) or for assessing ototoxicity (n = 135). Three hundred and six patients were included in the analysis. Post-chemotherapy ototoxicity was detected in 148 (48%) patients, and clinically-significant ototoxicity was present in 91 (30%). In addition, based on the ASHA criteria, 48% of patients (97/204) with long-term follow-up had further deterioration of their hearing after completion of treatment. CONCLUSIONS: Ototoxicity following chemotherapy with cisplatin or carboplatin is common and can frequently progress after the completion of treatment. Long-term follow-up is strongly recommended.

The effect of caffeine on hearing in a guinea pig model of acoustic trauma.

OBJECTIVE: Caffeine is a widely consumed substance affecting the metabolism of adenosine and cellular metabolism of calcium. Noise also affects these metabolic pathways while inducing hearing loss. The aim of this study was to determine the effect of daily intake of caffeine on hearing loss after an episode of acoustic trauma in guinea pigs. MATERIALS AND METHODS: In this pilot study, forty guinea pigs were randomly divided into four groups: group I (control, n=10) received intraperitoneal saline, group II (n=10) received intraperitoneal caffeine (120 mg/kg/day) for 14 days, group III (n=10) was exposed to noise (tone of 6 kHz at 120 dB for one hour) and group IV (n=10) was exposed to noise as group III and received caffeine as group II. Auditory brainstem responses were measured at four different frequencies (8, 16, 20, and 25 kHz) prior to and at intervals of 1h, 3 days, 10 days, and 14 days after the initial treatment. On day 14, morphological analysis was performed to assess the effects of caffeine on acoustic trauma. RESULTS: Aggravated hearing loss was observed in group IV after 10 days of follow-up. After 14 days, one of the four frequencies (8 kHz) tested showed statistically significant greater impairment in hearing (8.2 ± 3.6 dB, p=0.026). Auditory hair cells showed no difference while spiral ganglion cell counts were diminished in group IV (p<0.05). CONCLUSION: These findings indicate that caffeine may have a detrimental effect on hearing recovery after a single event of acoustic trauma.

Minimally Invasive OSIA Bone Conduction Hearing Implant (MOSIA) in Children: How I do it?

The MOSIA is a novel minimally invasive endoscopic-assisted technique that has been shown to reduce postoperative morbidity and improve aesthetics. This is the first series to include children under the age of 12, as the FDA in the United States only approved OSIA for children 12 and older. Laryngoscope, 134:1901-1906, 2024.

Onabotulinum Toxin A (BoNT-A) for Drooling in Children: A Systematic Review and Meta-Analysis.

INTRODUCTION: Sialorrhea, also known as drooling, hypersalivation, or ptyalism, has a significant impact on the medical and psychosocial well-being of children. Onabotulinum toxin A (BoNT-A) is the most commonly used botulinum toxin worldwide for the treatment of sialorrhea in children. OBJECTIVES: To conduct a comprehensive systematic review and meta-analysis to assess the clinical efficacy and potential adverse effects of BoNT-A as a treatment for drooling in children. METHODS: Cochrane, Embase, and Medline databases were systematically searched (up to May 2023). Out of 535 identified publications, 20 were found eligible for inclusion. A systematic review and meta-analysis were performed to determine the efficacy of BoNT-A treatment in children in reducing the frequency and severity of drooling. RESULTS: Out of the 20 studies included, a meta-analysis was conducted on the complete dataset of eight studies involving 131 patients. BoNT-A was found to significantly decrease the severity of drooling in patients with sialorrhea (standardized mean difference [SMD], -2.07; 95% confidence interval [CI], -2.91 to -1.23; p < 0.0001) when compared with the conditions before injections using random-effects models. Six studies out of 20 reported dysphagia as an adverse effect after injection. Other side effects included thickness of saliva and pain at the site of injection. CONCLUSION: BoNT-A is a clinically effective therapy that improves drooling severity in children with sialorrhea. Although there were some adverse side effects reported, they were transient and not severe. Future studies are needed to further evaluate the best techniques and to identify the ideal dosages required to achieve the optimal outcomes. Laryngoscope, 134:3012-3017, 2024.

Impact of Educational Activity Formats, Online or In-Person, on the Intention of Medical Specialists to Adopt a Clinical Behaviour: A Comparative Study.

COVID-19 accelerated continuing professional development (CPD) delivered online. We aimed to compare the impact of in-person versus online CPD courses on medical specialists' behavioural intentions and subsequent behaviour. In this comparative before-and-after study, medical specialists attended in-person courses on nine clinical topics. A second group attended an adapted online version of these courses. Behavioural intention and its psychosocial determinants were measured before and immediately after the courses. Behaviour change was measured six months later. Generalised estimating equation (GEE) models were used to compare the impact of course formats. A total of 82/206 in-person registrants (mean age: 52±10 years; 50% men) and 318/506 on-line registrants (mean age: 49±12 years; men: 63%) participated. Mean intention before in-person courses was 5.99±1.31 and 6.43±0.80 afterwards (average intention gain 0.44, CI: 0.16-0.74; p=0.003); mean intention before online courses was 5.53±1.62 and 5.98±1.40 afterwards (average intention gain of 0.45, CI: 0.30-0.58; p<0.0001). Difference in intention gain between groups was not statistically significant. Behaviour reported six months later was not significantly associated with post-course intention in either group. However, the intention difference increased significantly among those who said they had adopted the targeted behaviour (paired wilcoxon test: n = 40 and p-value=0.002) while it did not increase significantly in the group of those who had not adopted a targeted behaviour (paired wilcoxon test: n = 16 and p-value=0.223). In conclusion, the increase in intention of specialists after CPD courses was similar whether the course was in-person or online. Also, an increase in intention in both groups signalled more likelihood of adoption.

Can ChatGPT Replace an Otolaryngologist in Guiding Parents on Tonsillectomy?

Background: ChatGPT is an artificial intelligence tool, which utilizes machine learning to analyze and generate human-like text. The user-friendly accessibility of this tool enables patients conveniently access medical information without intricate terminology challenges. The objective of this study was to assess the accuracy of ChatGPT in providing insights into indications and management of complications after tonsillectomy, a common pediatric otolaryngology procedure. Methods: The responses generated by ChatGPT were compared to the "Clinical practice guidelines: tonsillectomy in children-executive summary" developed by the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF). An assessment was carried out by presenting predetermined questions regarding indications and complications post tonsillectomy to ChatGPT, followed by a comparison of its responses with the established guideline by 2 otolaryngology experts. The responses of both parties were reviewed by the senior author. Results: A total of 16 responses generated by ChatGPT were assessed. After a comprehensive review, it was concluded that 15 out of 16 (93.8%) responses demonstrated a high degree of reliability and accuracy, closely adhering to the standard established by the AAO-HNSF guideline. Conclusion: The results validate the potential of using ChatGPT to enhance healthcare delivery making guidelines more accessible to patients while also emphasizing the importance of ensuring the provision of accurate and reliable medical advice to patients.

Resonance Frequency Analysis Identifies Implant- and Host-Related Factors Associated With Bone-Anchored Hearing Implant Stability.

HYPOTHESIS: Resonance frequency analysis (RFA) is a reliable, noninvasive method to assess the stability of bone-anchored hearing implants (BAHIs), although surgical-, implant-, and host-related factors can affect its outcome. BACKGROUND: BAHI plays an important role in restoring hearing function. However, implant- and host-related factors contribute to premature implant extrusion. To mitigate this, noninvasive methods to assess implant stability, along with a better understanding of factors contributing to BAHI failure, are needed. METHODS: We evaluated the utility of RFA to quantify implant stability in sawbone (bone mimicking material), 29 human cadaveric samples, and a prospective cohort of 29 pediatric and 27 adult participants, and identified factors associated with implant stability. To validate the use of RFA in BAHI, we compared RFA-derived implant stability quotient (ISQ) estimates to peak loads obtained from mechanical push-out testing. RESULTS: ISQ and peak loads were significantly correlated (Spearman rho = 0.48, p = 0.0088), and ISQ reliably predicted peak load up to 1 kN. We then showed that in cadaveric samples, abutment length, internal table bone volume, and donor age were significantly associated with implant stability. We validated findings in our prospective patient cohort and showed that minimally invasive Ponto surgery (MIPS; versus linear incision), longer implantation durations (>16 wk), older age (>25 yr), and shorter abutment lengths (≤10 mm) were associated with better implant stability. Finally, we characterized the short-term reproducibility of ISQ measurements in sawbone and patient implants. CONCLUSIONS: Together, our findings support the use of ISQ as a measure of implant stability and emphasize important considerations that impact implant stability, including surgical method, implant duration, age, and abutment lengths.

Endoscopic repair of tracheoesophageal fistulas: A contemporary multi-institutional case series and literature review.

OBJECTIVES: Recurrent and primary tracheoesophageal fistulas (TEFs) are a challenging surgical pathology to treat, as standard open surgical approaches are associated with high morbidity and mortality. As such, endoscopic modalities have gained interest as an alluring alternative, yet variable success rates have been reported in the literature. The aim of this study was to provide a contemporary update of the literature and describe our institutional experience with the bronchoscopic obliteration of recurrent and primary TEFs. METHODS: Retrospective chart review of all pediatric patients having undergone endoscopic TEF repair at two pediatric academic centers in Montreal, Canada and Lille, France between January 1, 2008 to December 31, 2020. RESULTS: 28 patients with TEFs (20 recurrent, 8 primary) underwent a total of 48 endoscopic procedures. TEF repair was performed under endoscopic guidance using various combinations of techniques, including fistula de-epithelialization (endoscopic brush, thulium laser, trichloroacetic acid-soaked pledgets or electrocautery), tissue adhesives, submucosal augmentation, esophageal clip and stenting. Successful closure was achieved in 16 patients (57 %), while 12 (43 %) required eventual open or thoracoscopic repair. The mean number of endoscopic procedures was 1.7. There were no major treatment-related complications such as pneumothorax, mediastinitis or death (mean follow-up 50.8 months). CONCLUSIONS: Endoscopic repair of recurrent or primary TEFs is a valuable component of our therapeutic armamentarium and may contribute to decreased surgical morbidity in this complex patient population. Families should be counselled that endoscopic results may be more modest than with open or thoracoscopic approaches, and multiple procedures may be required.
