Purpose

To investigate the impact of 3D-printed temporal bone models with two different material transparencies on trainees’ mastoidectomy performance.

Methods

Eleven ORL residents performed two anatomical mastoidectomies with posterior tympanotomy on two 3D-printed models with different transparency and VR simulation training. Participants where divided into two groups based on their experience. Within each group participants were randomized to start with the model printed in a completely opaque material or in a material featuring some degree of transparency. After drilling on 3D-printed models, the participants performed two similar mastoidectomies on human cadavers: one on the left side of one cadaver and one on the right side of another cadaver.

After drilling 3D-printed models and cadavers, the final-product performances were evaluated by two experienced raters using the 26-item modified Welling Scale. Participants also evaluated the models using a questionnaire.

Results

Overall, the participants performed 25 % better on the 3D-printed models featuring transparency compared to the opaque models (18.6 points vs 14.9 points, mean difference = 3.7, 95 % CI 2.0–5.3, P < 0.001)). This difference in performance was independent of which material the participants had drilled first. In addition, the residents also subjectively rated the transparent model to be closer to cadaver dissection. The experienced group starting with the 3D-printed models scored 21.5 points (95 % CI 20.0–23.1), while the group starting with VR simulation training score 18.4 points (95 % CI 16.6–20.3).

Conclusion

We propose that material used for 3D-printing temporal bone models should feature some degree of transparency, like natural bone, for trainees to learn and exploit key visual cues during drilling.

Introduction

Flexible bronchoscopy under anesthesia is a mainstay diagnostic tool for evaluating respiratory disorders in pediatric patients. While flexible bronchoscopy is generally regarded as a safe procedure with low risk for major complications, it does entail additional risks associated with the use of general anesthesia. The use of diagnostic awake flexible bronchoscopy in children is not well documented in current literature.

Objectives

The objective of this case series is to investigate the feasibility and potential utility of awake flexible bronchoscopy in pediatric patients and to highlight important precautions and complications.

Methods

This was a consecutive case series of patients who underwent an awake flexible bronchoscopy over a two year period at a tertiary children's hospital. Data collection included demographics, indications, number of attempts, scope findings, and complications. Successful attempts of flexible bronchoscopy were defined by visualization of the trachea and mainstem bronchi while failed attempts include if the scope entered the esophagus or if cough, vocal fold adduction, or movement prevented the scope from entering the trachea.

Results

11 patients were involved in this study (mean age 20 months, age range 0d to 5y 1m, 72 % male). Common indications for bronchoscopy were suspicion of foreign body (5, 45.4 %), chronic cough (4, 36.4 %), and stridor (4, 36.4 %). The mean number of attempts until successful was 1.72 (range 1–3). One patient experienced a 30-s episode of gagging with mucinous emesis. There were no other complications. One patient ultimately underwent another flexible bronchoscopy under general anesthesia to confirm the findings and to evaluate the tertiary bronchioles and another patient underwent a surgical resection of an oral mass under general anesthesia after awake flexible bronchoscopy.

Discussion

Awake flexible bronchoscopy was well tolerated in this study and could serve as a useful diagnostic tool without necessitating anesthetic. However, further study is needed to compare awake flexible bronchoscopy with flexible bronchoscopy under general anesthesia. Additionally, the patients selected for this study were limited to those with minimal risk, such as patients without cardiac disease. Limitations of this technique include suboptimal visualization of subglottic region and limited diagnostic utility for sleep related airway pathologies and cases where therapeutic intervention is needed.

Background

High-risk neonates continuing to need enteral nutrition, but otherwise medically ready for discharge home from the NICU, are often offered ongoing hospitalization for nasogastric tube (NGT) feeding, versus discharge after placement of gastrostomy tube. Our group developed an interdisciplinary algorithm to support a third option—discharge home with enteral nutrition via NGT. Our objective was to develop a cross-institutional and interdisciplinary pathway to optimize outcomes for neonates discharged with NGTs.

Methods

A program to support home NGT feeding use was created, “Passport Home Program,” based upon feedback from parents, nurses, speech-language pathologists, otolaryngologists, and neonatal intensivists, amongst others, spanning four hospitals across our health system.

Results

Standardized educational materials for caregivers of neonates requiring ongoing NGT feeding on discharge were created and consist of an in-hospital curriculum with specific competency thresholds, including demonstrating NGT replacement and confirmation with pH test strips. A discharge kit, including a QR code for a video reviewing safe techniques for home NGT placement, is distributed, along with support staff contact information. Members of an emergency department were trained in neonatal NGT replacement in case of issues after business hours. Each patient is followed in a dedicated outpatient multi-disciplinary clinic.

Discussion

This is an interdisciplinary and multi-institutional effort to standardize a pathway for neonates discharged home from the NICU with NGTs. This has the potential to lead to earlier discharge, better outcomes for patients and families, as well as lower costs. This best practice algorithm serves as an example pathway applicable across fields of medicine.

Objective

Genetic variants in the OTOF gene are responsible for non-syndromic hearing loss with an autosomal recessive inheritance pattern. The objective of our work was to evaluate the clinical characteristics of patients with biallelic pathogenic variants in OTOF and their evolution after treatment.

Methods

A cohort of 124 patients with prelingual hearing loss, studied from 1996 to 2023, was included in this study. A genetic analysis was conducted to identify the type and frequency of variants in the OTOF gene and their relation to the clinical characteristics of the patients.

Results

The homozygous p. Gln829* variant in the OTOF gene was detected in 3 probands (2.4 %) of a group 124 individuals with prelingual hearing loss. Another 6 family members to a total of 9 individuals were finally included. All presented with severe/profound bilateral sensorineural hearing loss of congenital onset. Three of these individuals were diagnosed with auditory neuropathy spectrum disorder. One individual passed the OAE test during the screening program, and since he did not have risk factors for hearing loss that would warrant ABR testing, this led to a delay in his hearing loss diagnosis. Four individuals underwent cochlear implants (three bilateral) with good functional outcomes. In three of them. However, in 17 familial cases with heterozygous variants, either no hearing loss was observed or it was within the expected range for their age.

Conclusions

Hearing loss secondary to the p. Gln829* variant of the OTOF gene is relatively rare in our medical area. Its presence in homozygosity is the cause of severe/profound bilateral prelingual sensorineural hearing loss, responsible for auditory neuropathy with a good response to cochlear implantation.

Aim

Smell and taste are senses that contribute to a child's overall well-being. Disorders affecting these senses can impact a child's daily life from enjoying meals to detecting potential dangers through scent.

The aim of this study is to describe patient characteristics and etiological causes of olfactory (OD) and/or gustatory disorders (GD) in children referred to a smell and taste clinic. Secondly, we aim to suggest a clinical work up.

Methods

Retrospective study where data were collected from 57 children who were referred consecutively to the University Clinic for Flavour, Balance, and Sleep; Department of Otorhinolaryngology (ORL), Head and Neck Surgery; Goedstrup Hospital, Denmark, for assessment due to OD/GD from January 2017 to May 2023.

Results

Most of the children had anosmia (60 %), whereas sensation of the basic tastes was intact in all but eight children (16 %). The lowest TDI scores were in children with congenital OD. The underlying etiology was congenital followed by postinfectious mostly related to Covid-19. Picky eating including anorectic traits were seen in 16 % of patients.

Conclusion

The focus on smell loss in pediatric population is low, and probably does not adequately reflect either underlying prevalence in this group or the possible consequences on a child's well-being. Moreover, increased awareness of children's smell and taste loss is needed, as it may be associated with eating disturbances.

Aim

This study explored the value of Chirp-auditory brainstem response (ABR) thresholds in assessing the hearing threshold of children diagnosed with auditory neuropathy spectrum disorder (ANSD).

Methods

A total of 20 children with ANSD (40 ears, aged 1.5–7.0 years, median age 4.5 years) and 31 children with sensorineural hearing loss (SNHL) (52 ears, aged 0.9–8.0 years, median age 3.7 years) were included. Besides, 25 normal children (50 ears, aged 0.8–7.5 years, median age 4.6 years) were used as controls. Chirp-ABR and behavioral audiometry were performed simultaneously among three groups of children, allowing for a comparison of the thresholds obtained through both methods.

Results

In ANSD children, the correlation (r-values) between the thresholds obtained from Chirp-ABR and behavioral audiometry at 500–4000 Hz were 0.84, 0.67, 0.59, and 0.60, respectively. The average threshold differences between two methods ranged from 9.7 to 13.3 dB at 500–4000 Hz. Notably, 20 % ears (8/40) exhibited considerable discrepancies (>30 dB) in thresholds at certain frequencies. For SNHL children, the r-values between two methods were 0.84, 0.89, 0.92, and 0.93, respectively. The average threshold differences between two methods were 5.7–8.2 dB at 500–4000 Hz. Similarly, in normal children, the average threshold differences between two methods ranged from 6.1 dB to 7.7 dB, the r-values were 0.81, 0.78, 0.80, and 0.80 at 500–4000 Hz, respectively.

Conclusion

Chirp-ABR threshold is not suitable to predict the behavioral audiometry threshold in ANSD children. When there is a significant discrepancy (>30 dB) between Chirp-ABR thresholds and behavioral audiometry thresholds in hearing loss, ANSD should be highly suspected.

Background

Children with ADHD were found to have language impairment in many studies. The way they use language in their everyday life may be affected, namely, the pragmatic aspect of language. Measuring the affected parameters in all aspects of language will help to reach better rehabilitation. Thus, this study set out to observe relationships between hyperactivity/impulsivity and inattention with all language domains in 30 Egyptian Arabic-speaking children with ADHD between 4 and ≤7 years old with the aim of better intervention. Children were evaluated to establish the diagnosis of ADHD and its type following the diagnostic criteria of the DSM-V criteria and the Conners’ Parent Rating Scale-Revised. Language abilities were assessed by the Pre-school Language Scale 4th edition (Arabic version), the Arabic articulation test, and the Egyptian Arabic Pragmatic Language Test. This assessment covered receptive and expressive language abilities and phonological and pragmatic skills.

Results

Compared to norms, it was found that the ADHD children who participated in this study had non-significant language delays in the parameters of the modified PLS-4 test. 70 % of the ADHD children had total pragmatic test scores below their 5th percentile, while 30 % of the children had total pragmatic test scores above their 5th percentile. 50 % of ADHD children failed to master certain sounds corresponding to their phonological age. A statistically significant negative correlation was observed between each of the inattention and hyperactivity/impulsivity scores and the receptive, expressive, total language ages, and pragmatic language scores.

Conclusion

Children with ADHD in this study did not show major difficulties in areas beyond what would be expected in normally developing children. Most children with ADHD in the present study had problems with pragmatic language aspects that are correlated positively to ADHD symptoms. 50 % of ADHD children failed to master certain sounds corresponding to their chronological age.

Background

Patients with long-COVID suffer from symptoms that continue or develop after a COVID-19 or SARS-CoV-2 infection and are present for four or more weeks after the initial infection. This case series describes a group of previously healthy adolescent patients with long-COVID who were seen in a pediatric vestibular clinic for evaluation of severe dizziness and were diagnosed with persistent postural-perceptual dizziness (PPPD). By presenting their symptoms, management and treatment effects, this study aims to provide a diagnostic and therapeutic framework for providers who encounter these patients.

Methods

Patient records were reviewed for past medical history, symptoms, physical exam findings, results of audiometric and vestibular testing, dizziness handicap inventory for patient caregiver (DHI-pc) scores, and treatment recommendations. Parents of patients were contacted for a follow up survey to assess treatment adherence and outcomes including changes in symptoms and return to activity.

Results

A series of 9 adolescent patients were referred from a multidisciplinary long-COVID clinic and diagnosed with PPPD. Recommended treatment included vestibular physical therapy, selective serotonin reuptake inhibitor medication, and cognitive behavioral therapy. The majority of patients experienced an improvement in their symptoms, and all patients had improved activity levels and DHI-pc scores after treatment.

Conclusion

To the best of our knowledge, no previous reports exist discussing PPPD in long-COVID patients. This case series provides insight into symptom evolution and treatment efficacy in this patient population.

Objectives

To assess the safety and effectiveness of perioperative ibuprofen in pediatric tonsillectomy through a meta-analysis of relevant randomized controlled trials.

Methods

We conducted a comprehensive review of studies available in PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases up to June 2024. This analysis compared perioperative ibuprofen administration to control groups (saline, acetaminophen, or opioids). Outcomes assessed were postoperative pain management, as indicated by the frequency of analgesic use, and morbidity rates, which included the incidence of postoperative nausea and vomiting and post-tonsillectomy hemorrhage (PTH). PTH was further categorized as primary (occurring on the day of operation) or secondary (occurring after the day of operation), and classified as type 1 (observed at home or evaluated in the emergency department without further intervention), type 2 (requiring readmission for observation), or type 3 (necessitating a return to the operating room for hemorrhage control).

Results

This analysis included nine studies involving a total of 1545 patients. Incidences of primary PTH (OR = 1.0949, 95 % CI [0.4169; 2.8755], I² = 0.0 %), secondary PTH (OR = 1.6433 95 % CI [0.7783; 3.4695], I² = 0.1 %), and overall PTH (OR = 1.4296 95 % CI [0.8383; 2.4378], I² = 0.0 %) were not significantly higher in the ibuprofen group than the control groups. Administration of ibuprofen led to a significant decrease in postoperative nausea and vomiting (OR = 0.4228 95 % CI [0.2500; 0.7150], I² = 40.0 %) and frequency of postoperative analgesic uptake (OR = 0.4734 95 % CI [0.2840; 0.7893]; I² = 19.8 %). There was no difference in bleeding by type between the ibuprofen and control groups.

Conclusions

Our meta-analysis demonstrated that administration of ibuprofen for pediatric tonsillectomy did not significantly increase the incidence of postoperative bleeding but did decrease postoperative emesis and improve pain control.

Objective

Since December 2021, the number of children with COVID-19 infections has increased. Sequelae in children have not been well-described. Our goal was to determine if children with a history of COVID-19 infection (C19 group) were more likely to present with recurrent acute otitis media (rAOM) or post-ventilation tube otorrhea (VTO) than children who had no history of COVID-19 infection (NoC19 group).

Methods

Charts of consecutive children presenting at a pediatric otolaryngology clinic from March–May 2022 were reviewed. Demographics, COVID-19 test history, comorbidities, ultimate diagnosis, physical exam findings, and management plan were included. No children had a known COVID-19 infection at the time of visit.

Results

524 children were included, 228 (43.5 %) girls and 296 (56.5 %) boys. Mean age was 5 years (95 % CI 4.6–5.4). 115 (21.9 %) had a history of COVID-19 infection.

104 (19.8 %) had a diagnosis of rAOM or VTO, 26.1 % (30/115) children in C19 and 18.1 % (74/409) children in NoC19 (Fisher's Exact p = .04, OR = 1.6). For children without ventilation tubes in place, 23.5 % (27/115) in C19 had rAOM versus 15.2 % (62/409) in NoC19 (p = .03, OR = 1.7). 18.3 % (21/115) of the C19 group had nasal congestion compared to 6.6 % (27/409) of the NoC19 group (p < .001, OR = 3.2). There was no difference in incidence of otitis media with effusion, tonsil/adenoid hypertrophy, sleep-disordered breathing, or epistaxis between the groups.

Conclusion

Infection with COVID-19 may be associated with an increased risk of rAOM and VTO in children. This may affect healthcare utilization by increasing the need for pediatric and otolaryngologic care.
