The Role of Airway Management on Feeding Difficulties in Children With Pfeiffer Syndrome.

BACKGROUND: Pfeiffer syndrome is characterized by craniosynostosis, mid-face hypoplasia, broad thumbs, and often multilevel airway obstruction. Airway management is often required, including the use of positive airway ventilation, nasopharyngeal airway (NPA), or tracheostomy. OBJECTIVE: The objective of this study was to assess the impact an airway adjunct can have on feeding difficulties in children with Pfeiffer syndrome. METHODS: Retrospective review of patients diagnosed with Pfeiffer syndrome from January 1998 to January 2020 at one of England's 4 supraregional Craniofacial Units, Alder Hey Children's Hospital. Speech & Language Therapy case notes and medical notes were used to gather data, as well as the Oral Feeding Score component of the UK Craniofacial Outcome Score. RESULTS: Eleven patients were included. Six patients had no airway adjunct (55%): 3 had tracheostomy (27%) and 2 patients had NPA (18%). All patients with airway adjuncts were percutaneous endoscopic gastrostomy/percutaneous endoscopic jejunostomy fed. Those who did not require an airway adjunct had an Oral Feeding Score of 4.60 (SD: 0.49). The children who went on to have an airway adjunct had a mean preintervention Oral Feeding Score of 2.4 (SD: 0.8). The mean feeding score (postairway adjunct) in the NPA group was 2.0, compared with the tracheostomy group scoring 3.0. CONCLUSIONS: Children with Pfeiffer syndrome who require airway intervention have more significant feeding problems requiring feeding intervention. Although there were small numbers included in this study, there is a suggestion that airway adjuncts can contribute to feeding difficulties, particularly NPAs.

Droplet and bone dust contamination from high-speed drilling during mastoidectomy.

OBJECTIVES: The aim of this study was to examine contamination from otolaryngologic procedures involving high-speed drilling, specifically mastoid surgery, and to assess the adequacy of PPE in such procedures. DESIGN AND SETTING: Mastoid surgery was simulated in a dry laboratory using a plastic temporal bone, microscope and handheld drill with irrigation and suction. Comparisons of distance of droplet and bone dust contamination and surgeon contamination were made under differing conditions. Irrigation speed, use of microscope and drill burr size and type were compared. MAIN OUTCOME MEASURES: Measurement of the distance of field contamination while performing simulated mastoidectomy and location of surgeon contamination. RESULTS: There was a greater distance field contamination and surgeon contamination without the use of the microscope. Contamination was reduced by using a smaller drill burr and by using a diamond burr when compared to a cutting burr. The use of goggles and a face mask provided good protection for the surgeon. However, the microscope alone may provide sufficient protection to negate the need for goggles. CONCLUSIONS: While the risks of performing mastoid surgery during the coronavirus pandemic cannot be completely removed, they can be mitigated. Such factors include using the microscope for all drilling, using smaller size drill burrs and creating a safe zone around the operating table.

Suprathreshold measures of taste perception in children - Association with dietary quality and body weight.

Childhood obesity is an increasing problem in the Western world, and is affected by a multitude of interacting factors. Recent evidence suggests that taste perception may differ between obese and normal weight children. Evidence also suggests that perception of sweet and bitter taste is linked to differential food liking of various foods. To date, most studies have focused on single food items or food groups, rather than an overall view of dietary quality, and mainly on bitterness. Thus it is unclear whether taste perception is associated with dietary quality in children. Our objective was to examine the link between taste perception, dietary quality and body weight in Irish school children, in conjunction with other known influences of body weight. Taste perception was measured using the gLMS for bitter, salty and sweet stimuli. Detailed dietary intake data were collected from 525 children aged 7-13 via a 3-day diet history. Energy misreporters were identified and excluded from the dietary analyses, leaving n = 483 children. Dietary quality was assessed using Healthy Eating Index. Salivary DNA was collected and analyzed for variations in the bitter receptor gene TAS2R38. Sex differences were observed whereby intensity perception of sweetness was lower in the overweight/obese males, while no association was observed for sweet taste in the females. Despite the differences in weight status, taste perception was not associated with differences in overall dietary quality, measured via HEI score, in this cohort. Prospective cohort studies in children are necessary to better understand the association between taste intensity, food intake and weight over time.

A multicentre observational study of paediatric head and neck abscesses.

INTRODUCTION: In winter of 2022/3 paediatric ENT surgeons across the UK observed that the incidence of severe abscesses in the head and neck and associated complications was higher than seen in previous years. We aimed to collate and evaluate data from across the UK to establish if this was a true rise in cases, and to describe the factors associated. METHODS: A multicentre retrospective data collection was undertaken from 13 units across the UK. Patients admitted between September 2022-February 2023 with a head and neck abscess including sinogenic, otogenic, deep and superficial neck abscesses were included. Demographic, disease specific, management and outcome data were collected. Hospital episode statistic data were also requested and analysed to allow for comparison with previous 10 years of head and neck abscesses. RESULTS: 262 patients with abscesses of the head and neck were admitted during the study period, 100 between September and November and 163 between December and February. Mastoid abscesses were the most common abscess across both groups. The rate of group A streptococcus + culture results rose significantly from 12 % in autumn group to 30 % in winter (p = 0.02). The rate of intracranial complications rose from 10 % to 18 % (p = 0.11) and the rate of venous thrombosis rose over the same timeframe from 3 % to 14 % (p = 0.01). DISCUSSION: This study demonstrated a statistically significant rise in the rate of group A streptococcus associated abscesses when comparing Autumn and Winter 2022/2023. Over the same timeframe a statistically significant rise in the proportion of patients with venous thromboses associated with H&N abscesses was noted. Interestingly, despite perceived national consensus regarding a spike in abscess incidence, the number of abscesses seen in winter 2022/2023 was in keeping with expected rates of paediatric H&N abscesses, based on pre covid year-on-year rise in incidence.

Is nurse-led telephone follow-up for post-operative obstructive sleep apnoea patients effective? A prospective observational study at a paediatric tertiary centre.

OBJECTIVES: To assess the effectiveness and patient satisfaction of a nurse-led telephone follow-up service in children following surgery for sleep disordered breathing (SDB)/obstructive sleep apnoea (OSA) in a tertiary paediatric hospital. DESIGN: Prospective observational uncontrolled study. PARTICIPANTS: Children under the age of 16 undergoing adenoid and/or tonsil surgery between June 2015 and June 2018 for SDB or OSA. Parents were contacted by telephone six weeks post-operatively by an ENT nurse specialist. The T-14 questionnaire was utilised to assess post-operative outcomes. Parents were subsequently asked to evaluate their experience of this nurse-led telephone consultation service between June 2016 and April 2017. RESULTS: 535 patients were included with an average post-operative T-14 score of 2.13 (95% CI 1.7-2.5). 430 patients were discharged following the nurse-led telephone consultation with a mean post-operative T-14 score 1.0 (95% CI 0.8-1.2). 105 patients were subsequently reviewed in clinic with an average T-14 score of 6.88 (95% CI 5.25-8.51). 36 (6.7%) patients had ongoing symptoms of SDB or OSA. 55 parents were invited to provide an evaluation of the nurse-led telephone FU clinic, which showed a 100% satisfaction rate with the service. CONCLUSION: A nurse-led telephone follow-up service is efficient and safe with high levels of parental satisfaction. It reduces unnecessary follow-up of uncomplicated patients whilst providing a robust safety net for those with ongoing problems.

Using Cross-Cultural Consumer Liking Data to Explore Acceptability of PGI Bread-Waterford Blaa.

Waterford Blaa is one of only four Irish food products granted protected geographical (PGI) status by the European Commission. This study aimed to determine whether cultural background/product familiarity, gender, and/or age impacted consumer liking of three Waterford Blaa products and explored product acceptability between product-familiar and product-unfamiliar consumer cohorts in Ireland and the UK, respectively. Familiarity with Blaa impacted consumer liking, particularly with respect to characteristic flour dusting, which is a unique property of Waterford Blaa. UK consumers felt that all Blaas had too much flour. Blaa A had the heaviest amount of flouring and was the least preferred for UK consumers, who liked it significantly less than Irish consumers (p < 0.05). Flavour was also important for UK consumers. Blaa C delivered a stronger oven baked odour/flavour compared to Blaa A and was the most preferred by UK consumers. Irish consumer liking was more influenced by the harder texture of Blaa B, which was their least preferred product. Age and gender did not impact liking for Blaas within Irish consumers, but gender differences were observed among UK consumers, males liking the appearance significantly more than females. This is the first paper comparing Waterford Blaa liking of naïve UK consumers with Irish consumers familiar with the product.

Transoral laser microsurgery and radiotherapy for oropharyngeal squamous cell carcinoma: Equitable survival and enhanced function compared with contemporary standards of care.

INTRODUCTION: We describe the 5-year oncological and functional outcomes of transoral laser microsurgery, neck dissection (TLM + ND) and adjuvant radiotherapy (PORT) used to treat patients with oropharyngeal carcinoma. The effectiveness of external carotid artery (ECA) ligation in reducing post-operative bleeding, and fibrin glue following ND in reducing wound drainage and length of hospital stay is reported. MATERIALS AND METHODS: This retrospective case review of consecutive patients undergoing TLM between 2006 and 2017 used the Kaplan-Meier Estimator and Log-Rank Test for univariate, time-to-event analyses, and Cox-Proportionate Hazard modelling for multivariate analysis. RESULTS: 264 consecutive patients were included. Mean follow-up was 49.4 months. 219 (82.9%) patients received PORT. Five-year overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) rates were 74.9%, 73.7%, and 86.2%, respectively. Five-year locoregional control was 89.4%. 65.5% of cases were Human papillomavirus associated (HPV+), for whom OS, DFS and DSS was 85.6%, 84.7% and 92.7%, respectively, and demonstrated significantly higher OS (hazard ratio (HR) 0.28, CI 0.16-0.49, p < 0.0001), DFS (HR 0.28, CI 0.17-0.47, p < 0.0001) and DSS (HR 0.2, CI 0.09-0.44, <0.001). Post-operative oropharyngeal bleeding occurred in 23 patients (8.7%), of which 5 were major/severe, in patients without ECA ligation. Fibrin glue significantly reduced neck drain output (p < 0.001), and length of hospital stay (p < 0.001). One-year gastrostomy dependence rate was 2.3%. CONCLUSIONS: TLM + ND + PORT results in favourable 5-year survival and locoregional control rates, and low feeding tube dependency rates. ECA ligation and fibrin glue appear to reduce major post-operative haemorrhage, wound drainage and length of hospital stay.

Is tonsillectomy mandatory for asymmetric tonsils in children? A review of our diagnostic tonsillectomy practice and the literature.

INTRODUCTION: Diagnostic tonsillectomy is performed to exclude malignancy. It is associated with a post-operative hemorrhage rate of 3.5%, (1) which is more dangerous in small children. No previous case series for asymmetrical tonsils have detected tonsil lymphoma.(2-6) We aimed to review our local diagnostic tonsillectomy practice. METHOD: The authors reviewed the clinical notes and histological results for all diagnostic tonsillectomies carried out from June 2013 to June 2016. RESULTS: We recorded data for 168 patients. There were four post-operative bleeds and one return to theatre. Bilateral tonsillectomies accounted for 152 operations (90.5%). Lymphoid hyperplasia accounted for 95% of histological diagnosis with no malignancies found. Pre-operative tonsil grading demonstrated no statistically significant association with histological tonsil weight difference (ANOVA p = 0.10). Actinomyces colonisation had little affect on tonsil weight difference when we compared patients with bilateral colonisation and no colonisation (t-test p = 0.540) and between tonsils in patients with unilateral tonsil Actinomyces colonisation (paired t-test p = 0.448). Recurrent tonsillitis was more prevalent in patients with Actinomyces colonisation than OSA/sleep disordered breathing (39% vs 15%). CONCLUSION: A literature search yielded five smaller case series of palatine tonsil asymmetry in children with no malignancy found.(2-6) Case-control studies report tonsillar asymmetry as the most common presenting symptom (73%) in tonsillar lymphoma.(7) This enlargement usually occurs rapidly within 6 weeks with new obstructive or systemic B-type symptoms.(3) A Turkish epidemiological study found asymmetrical tonsils in 1.7% of the healthy paediatric population.(8) We therefore estimate there to be over 210,000 children with asymmetrical tonsils in the UK. With an unreliable grading system, we believe asymmetrical tonsils in isolation, unchanged for over 6 weeks may not warrant tonsillectomy.

Cochlear implantation in adolescents: Factors influencing compliance.

OBJECTIVES: To quantify rates of non- and partial-use of cochlear implants (CIs) in adolescent patients implanted in adolescence and childhood and identify factors influencing compliance. METHODS: A retrospective case note review undertaken at The Manchester Auditory Implant Centre. Adolescents were defined as young people aged 11-18 years. Individuals implanted in adolescence were defined as Group 1, individuals implanted in childhood under the age of 3 years and currently adolescents were defined as Group 2 and individuals implanted between the age of 3 and11 years and currently adolescents were defined as Group 3. Non-use was defined as not using the CI at all and partial use was defined as consistently using the CI less than full-time, or fluctuating periods of full and less than full-time use. RESULTS: In Group 1 there was 1 non-user (1.3%) and 11 partial-users (13.9%), with an overall non-compliance rate of 15.2%. In Group 2 there was one non-user (1.9%) and one partial-user (1.9%) with an overall non-compliance rate of 3.8%. In Group 3 there were no non-users and eight partial-users (9%), with an overall non-compliance rate of 9%. The factors influencing compliance differed between groups with the most common factor in Group 1 being a preference for the auditory input gained from the contralateral hearing aid (50%). In Groups 2 and 3 the main factors influencing compliance were behavioural and related to wearing the implant only at school (50 and 75%, respectively). CONCLUSIONS: Patients implanted during adolescence have higher rates of non- and partial-use compared with their adolescent counterparts who have been implanted during childhood. It is important to investigate factors influencing non-compliance so appropriate support may be provided to the patient and their family.

Bitter taste perception and dietary intake patterns in irish children.

BACKGROUND/AIMS: Variations in bitter receptor gene TAS2R38 affect the perception of bitter-tasting compound 6-n-propylthiouracil (PROP). The perception of PROP has been associated, in some reports, with the perception of fat and sweet tastes, and various food preferences and intakes. The aim was to investigate nutrient intakes and food patterns in a group of Irish children, using K-means cluster analysis, and compare these with TAS2R38 genotype and PROP taster status. METHODS: Dietary intake was measured via a 3-day diet history in 483 children aged 7-13 years. Children were genotyped for TAS2R38 variation, and PROP taster status was assessed. Anthropometric and socioeconomic data were also obtained. RESULTS: No differences were observed in macronutrient, micronutrient, or food group consumption between the TAS2R38 genotype and PROP taster groups. K-means cluster analysis identified two distinct dietary patterns, termed 'more healthful' and 'less healthful' clusters. The clusters did not differ in frequencies of TAS2R38 genotype nor PROP taster status groups, suggesting that dietary patterns are not influenced by bitter taste perception. CONCLUSION: Bitterness perception, as measured by either TAS2R38 genotype or PROP taster status, does not appear to exert a significant effect on patterns of dietary intakes.
