Abstract
PURPOSE Exploring a possible link between upper airway inflammation and the development of cholesteatoma by studying the association between mucosa-affecting diseases of the upper airways and cholesteatoma surgery. METHODS This is a nationwide case-control study of 10,618 patients who underwent surgery for cholesteatoma in Sweden between 1987 and 2018. The cases were identified in the National Patient Register and 21,235 controls matched by age, sex and place of residency were included from national population registers. Odds ratios (OR) and corresponding 95% confidence intervals were used to assess the association between six types of mucosa-affecting diseases of the upper airways and cholesteatoma surgery. RESULTS Chronic rhinitis, chronic sinusitis and nasal polyposis were more common in cholesteatoma patients than in controls (OR 1.5 to 2.5) as were both adenoid and tonsil surgery (OR > 4) where the strongest association was seen for adenoid surgery. No association was seen between allergic rhinitis and cholesteatoma. CONCLUSION This study supports an association between mucosa-affecting diseases of the upper airways and cholesteatoma. Future studies should aim to investigate the mechanisms connecting mucosa-affecting diseases of the upper airways and cholesteatoma formation regarding genetic, anatomical, inflammatory and mucosa properties.

[PMID: 38700144 DOI: 10.1111/coa.14169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 12/28/2023] [Accepted: 04/13/2024] [Indexed: 05/05/2024]
Abstract
INTRODUCTION Leukotrienes play a significant role in the pathogenesis of adenoid hypertrophy (A.H.). Therefore, we aimed to analyse the role of montelukast, a leukotriene receptor antagonist, alone or in combination with mometasone, a potent local intranasal steroid, for the treatment of A.H. METHODS Participants were children with A.H. were treated with montelukast alone or montelukast and mometasone furoate. The main outcome measures were effect of montelukast on clinical symptoms of A.H. A literature review was conducted using online search engines, Cochrane Library, PubMed, Web of Science and Scopus, for randomized clinical trials assessing children with A.H. treated with montelukast alone or montelukast and mometasone furoate. Seven randomized clinical trials (RCTs) were included with 742 children. RESULTS Our study reveals that montelukast alone or in combination with intranasal mometasone furoate significantly improves clinical symptoms of adenoid hypertrophy such as snoring, sleeping disturbance, mouth breathing and A/N ratio. Montelukast was superior to placebo in decreasing snoring (SMD = -1.00, 95% CI [-1.52, -0.49]), sleep discomfort (SMD = -1.26, 95% CI [-1.60, -0.93]), A/N ratio (MD = -0.11, 95% CI [-0.14, -0.09]) and mouth breathing (SMD = -1.36, 95% CI [-1.70, -1.02]). No difference was detected between montelukast and mometasone versus mometasone alone in snoring (SMD = -0.21, 95%CI [-0.69, 0.27]); however, the combination group was superior to the mometasone alone in mouth breathing (SMD = -0.46, 95% CI [-0.73, -0.19]). CONCLUSIONS The limitation of studies included a small sample size, with an overall low to medium quality. Thus, further larger, higher-quality RCTs are recommended to provide more substantial evidence.

Abstract
BACKGROUND There is increasing interest in elucidating the relationship between adenoid hypertrophy (AH) and allergic rhinitis (AR). However, the impact of aeroallergen sensitization patterns on children with AH and AR remains unclear. METHODS Patients aged 2-8 years (recruited from January 2019 to December 2022) with nasal symptoms were assessed for allergies, adenoid size, and respiratory viral infection history. The serum total immunoglobulin E (IgE) and specific IgE levels were measured, and flexible nasal endoscopy was performed. The relationship between AH, aeroallergen sensitization patterns, and lymphocyte subpopulations in adenoid samples was analyzed using flow cytometry. RESULTS In total, 5281 children were enrolled (56.5% with AR; and 48.6% with AH). AH was more prevalent in children with AR. Compared to nonsensitized individuals, those polysensitized to molds had a higher prevalence of AH (adjusted OR 1.61, 95% CI 1.32-1.96) and a greater occurrence of two or more respiratory viral infections, particularly in adenoidectomy patients. The percentages and corrected absolute counts of regulatory T (Treg) cells, activated Tregs, class-switched memory B cells (CSMBs), natural killer (NK) T cells, and NK cell subpopulations were reduced in the adenoid tissues of children with both AH and AR (AH-AR) compared to AH-nAR children. Polysensitization in AH-AR children correlated with lower CSMB percentages. CONCLUSION Polysensitivity to molds is associated with an increased risk of AH in children with AR. Fewer B cells, NK cells, and Treg cells with an effector/memory phenotype were detected in the adenoids of AR children, and these lower percentages of immune cells, particularly CSMBs, were closely linked to aeroallergen sensitization models and respiratory viral infection.

Abstract
PURPOSE This study aimed to examine the effectiveness of the combined maximal medical treatment for adenoid hypertrophy in preschool children. METHODS Sixty-four children underwent one-year combined therapy with intranasal mometasone furoate, oral desloratadine, nasal saline irrigation, and bacteriotherapy. Additionally, decongestion drops were applied during scheduled breaks. RESULTS Of the 64 treated children, 72% showed clinical improvement in adenoid symptoms while 28% did not improve and underwent surgery. These groups differed significantly in terms of the overall reduction in ailments after treatment (p < 0.001), infection rate (p < 0.001), catarrh severity (p < 0.001) and nasal patency (p < 0.001). Endoscopic examination confirmed that responders experienced, on average, a decrease of 8.4% in the adenoid/choana ratio and an improvement in mucosal coverage of the adenoid. These effects were not observed in the group of children whose parents opted for surgery after nine months of conservative treatment. CONCLUSIONS The proposed new schema of long-term maximal medical treatment with the use of combined intermittent treatment of intranasal mometasone furoate and decongestion drops, oral desloratadine, nasal saline irrigation, and bacteriotherapy can be attempted in patients with adenoid hypertrophy symptoms, and responders may avoid the need for surgery. The applied treatment breaks resulted in a low number of therapeutic side effects.

Abstract
INTRODUCTION Class II malocclusion with mandibular retrognathia is a common complication of paediatric obstructive sleep apnoea (OSA), often accompanied by transverse maxillary deficiency. In early orthodontic treatment, a twin block (TB) is a regular functional appliance for correcting this malocclusion. For paediatric OSA, the most common risk factor is adenotonsillar hypertrophy (AHT). Untreated AHT may lead to the persistence and worsening of obstructive sleep-disordered breathing traits, including habitual mouth breathing. Additionally, the clockwise mandibular rotation associated with AHT-induced pharyngeal crowding can undermine the effectiveness and stability of TB treatment. Adenotonsillectomy (T&A) is currently the first-line treatment for paediatric OSA. This proposed trial will investigate the impact of T&A surgery timing on the efficacy and stability of TB functional treatment in children with class II mandibular retrognathia and ATH. METHODS AND ANALYSIS This will be a single-centre, parallel-group, superiority randomised controlled trial with participants randomised to intervention (T&A followed by TB treatment) or control arms (TB treatment followed by T&A) in a 1:1 ratio. A total of 40 patients aged 8-14 years, diagnosed with class II mandibular retrognathia and co-existing ATH-induced OSA, and indicated for both T&A surgery and TB treatment, will be recruited at the School and Hospital of Stomatology, Wuhan University. The primary outcomes will be the changes in the apnoea-hypopnoea index and the point A-nasion-point B angle from baseline to postorthodontic treatment between the two groups. Secondary outcomes will include other dental, skeletal, upper airway and soft tissue changes, as well as subjective sleep-related and oral-related quality of life. Outcome changes within each group and between groups will be analysed. ETHICS AND DISSEMINATION This study is approved by the Ethics Committee of the School and Hospital of Stomatology, Wuhan University (no. 2022-D07). The research findings will be faithfully disseminated through scientific conferences or published articles. TRIAL REGISTRATION NUMBER ChiCTR2200061703 (https://www.chictr.org.cn).

Abstract
BACKGROUND Adenoid hypertrophy (AH) is a common pediatric disease that significantly impacts the growth and quality of life of children. However, there is no replicable and valid model for AH. METHODS An AH rat model was developed via comprehensive allergic sensitization, chronic inflammation induction, and chronic intermittent hypoxia (CIH). The modeling process involved three steps: female Sprague-Dawley rats (aged 4-5 weeks) were used for modeling. Allergen sensitization was induced via intraperitoneal administration and intranasal provocation using ovalbumin (OVA); chronic nasal inflammation was induced through intranasal lipopolysaccharide (LPS) administration for sustained nasal irritation; CIH akin to obstructive sleep apnea/hypopnea syndrome was induced using an animal hypoxia chamber. Postmodel establishment, behaviors, and histological changes in nasopharynx-associated lymphoid tissue (NALT) and nasal mucosa were assessed. Arterial blood gas analysis and quantification of serum and tissue levels of (interleukin) IL-4 and IL-13, OVA-specific immunoglobulin E (sIgE), eosinophil cationic protein (ECP), tumor necrosis factor (TNF-α), IL-17, and transforming growth factor (TGF)-β were conducted for assessment. The treatment group received a combination of mometasone furoate and montelukast sodium for a week and then was evaluated. RESULTS Rats exhibited notable nasal symptoms and hypoxia after modeling. Histopathological analysis revealed NALT follicle hypertrophy and nasal mucosa inflammatory cell infiltration. Elevated IL-4, IL-13, IL-17, OVA-sIgE, ECP, and TNF-α levels and reduced TGF-β levels were observed in the serum and tissue of model-group rats. After a week of treatment, the treatment group exhibited symptom and inflammatory factor improvement. CONCLUSION The model effectively simulates AH symptoms and pathological changes. But it should be further validated for genetic, immunological, and hormonal backgrounds in the currently used and other strains and species.

Numerical and experimental evaluation of nasopharyngeal aerosol administration methods in children with adenoid hypertrophy. Int J Pharm 2024; 653:123906.

Abstract
Administering aerosol drugs through the nasal pathway is a common early treatment for children with adenoid hypertrophy (AH). To enhance therapeutic efficacy, a deeper understanding of nasal drug delivery in the nasopharynx is essential. This study uses an integrated experimental, numerical modelling approach to investigate the delivery process of both the aerosol mask delivery system (MDS) and the bi-directional delivery system (BDS) in the pediatric nasal airway with AH. The combined effect of respiratory flow rates and particle size on delivery efficiency was systematically analyzed. The results showed that the nasopharyngeal peak deposition efficiency (DE) for BDS was approximately 2.25-3.73 times higher than that for MDS under low-flow, resting and high-flow respiratory conditions. Overall nasopharyngeal DEs for MDS were at a low level of below 16 %. For each respiratory flow rate, the BDS tended to achieve higher peak DEs (36.36 % vs 9.74 %, 37.80 % vs 14.01 %, 34.58 % vs 15.35 %) at smaller particle sizes (15 µm vs 17 µm, 10 µm vs 14 µm, 6 µm vs 9 µm). An optimal particle size exists for each respiratory flow rate, maximizing the drug delivery efficiency to the nasopharynx. The BDS is more effective in delivering drug aerosols to the nasal cavity and nasopharynx, which is crucial for early intervention in children with AH.

Abstract
OBJECTIVE This study aimed to evaluate sleep patterns and investigate differences in clinical features among young individuals with snoring and obstructive sleep apnea (OSA). METHODS Data from 213 children and adolescents who underwent polysomnography (PSG) for primary snoring or OSA were collected between July 2017 and December 2021. To analyze differences in sleep architecture, hypoxia levels, and other clinical features, the participants were divided into two age groups: a preschool group and a school-age group. RESULTS The school-age group had significantly higher apnea-hypopnea index, obstructive apnea index, oxygen desaturation index, and body mass index than the preschool group. Both the lowest and average oxygen saturation levels were lower in the school-age group. Adenoid hypertrophy was more prevalent in the preschool group. The rate of overweight or obesity was 35.6% in the preschool group and even 94.2% in the school-age group. There were higher percentages of N1 and N2 sleep stages, and lower percentages of N3 and REM sleep stages in the school-age group. The groups exhibiting moderate to severe OSA demonstrated significant alterations in the difference between sleeping and waking diastolic blood pressure. CONCLUSION There is a higher frequency of respiratory events among school-age children compared with their preschool peers. Moreover, alterations in sleep structure are more prominent in the school-age group. Adenoid hypertrophy may serve as the primary instigator of OSA in preschool children, whereas the predominant causes in school-age children may be obesity or excessive weight.

Tamir SO, Schwarz Y, Hazan I, Cohen Michael O, Tshori S, Marom T. Medical treatment does not reduce surgery rates in children with adenoid hypertrophy. Int J Pediatr Otorhinolaryngol 2024; 176:111836. [PMID: 38154416 DOI: 10.1016/j.ijporl.2023.111836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 12/01/2023] [Accepted: 12/22/2023] [Indexed: 12/30/2023]
Abstract
OBJECTIVE We sought to study adenoidectomy rates in children with adenoid hypertrophy (AH) who were either treated with medical therapy or not during a 2-year follow-up period in a longitudinal population-based study. METHODS We retrospectively identified healthy children aged 1-18 years between 2014 and 2020 with AH diagnosis from the Clalit Health Services database, the largest healthcare maintenance organization in Israel. The main outcome was adenoidectomy alone or in combination with other procedures performed within 2 years after diagnosis. The treatment group consisted of children who received medical therapy, defined as a pharmacy purchase of montelukast, nasal steroid sprays and/or antihistamines (medical therapy aimed to reduce AH) for ≥2 consecutive months, while the control group consisted of untreated children. RESULTS We identified 68,356 unique children with AH, of them 56 % were boys, with a mean age of 4.9 ± 3.3 years. Of them, 5310 (7.7 %) received medical therapy. Overall, 6633 (9.7 %) underwent adenoidectomy within 2 years following diagnosis. There was no significant difference in surgery referral rates between the treatment and the control groups, 10 % vs. 9.7 %, respectively (p = 0.3). When adjusted for age and sex, the likelihood of undergoing adenoidectomy was similar in both groups (HR = 0.98, 95 % CI = 0.90-1.07, p = 0.6). Among operated children, the average time from diagnosis to surgery was statistically significantly longer in the treatment group than in the control group, 346 ± 180 vs 311 ± 175 days (p < 0.001). CONCLUSION Prescribing montelukast, nasal steroids and/or oral antihistamines was not associated with a reduction in adenoidectomy rates and was associated with an average surgery delay of 35 days.

The Prevalence of Obstructive Sleep Apnea and Associated Symptoms among Patients with Sickle Cell Disease: A Systematic Review and Meta-analysis. Hemoglobin 2023; 47:215-226. [PMID: 38102839 DOI: 10.1080/03630269.2023.2290507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 11/27/2023] [Indexed: 12/17/2023]
Abstract
Previous studies have shown that patients with sickle cell disease (SCD) are at high risk for obstructive sleep apnea (OSA). In the current study, we aimed to systematically review the literature to address the prevalence of OSA and associated symptoms among patients with SCD. Electronic databases, including Web of Science, Scopus, PubMed, Google Scholar, and Embase were systematically searched to identify the relevant original articles on patients with SCD. Newcastle Ottawa scale was used for quality assessment. Data were pooled by using random effects models. Subgroup analyses were performed by age groups. Thirty-nine studies containing details of 299,358 patients with SCD were included. The pooled results showed that more than half of these patients had OSA with different severities. The prevalence rates of OSA among children with apnea hypopnea index (AHI) cutoffs of above 1, 1.5, and 5 were 51% (95% confidence interval (CI) 36-67%), 29% (95% CI 19-40%), and 18% (95% CI 14-23%), respectively. The prevalence of OSA among adults with AHI cutoff of 5 was 43% (95% CI 21-64%). The pooled rates of snoring, nocturnal enuresis, nocturnal desaturation, and daytime sleepiness were 55% (95% CI 42-69%), 37% (95% CI 33-41%), 49% (95% CI 26-72%), and 21% (95% CI 12-30%), respectively. Given the high prevalence of OSA in patients with SCD, probable greater burden of SCD complications, and irreversible consequences of OSA, screening for OSA symptoms and signs seems useful in these patients. By screening and identifying this heterogeneous disorder earlier, available treatment modalities can be individualized for each patient.

Lan Y, Chen J, Chen S, He Y, Huang F. Influences of Adenoid Hypertrophy on Children's Maxillofacial Development. Healthcare (Basel) 2023; 11:2812. [PMID: 37957957 PMCID: PMC10647577 DOI: 10.3390/healthcare11212812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 10/07/2023] [Accepted: 10/18/2023] [Indexed: 11/15/2023] Open
Abstract
This study aims to investigate the association between adenoid hypertrophy and facial development. A total of 388 children aged 1-13 years old who had undergone head MRI in Foshan Maternal and Child Health Hospital were collected, including 196 hypertrophic cases and 192 normal cases. The maxillofacial soft tissue indicators were measured and compared. The A/N ratio and adenoid thickness consistently increased with age in the hypertrophic group and the A/N ratio reached a maximum value three years earlier than the normal group. The pharyngeal airway space, vallecula of epiglottis to anterior plane distance of the third/fourth cervical vertebrae, angle of convexity, total angle of convexity, and the nasolabial angle in the hypertrophy group were smaller than those in the control group (p < 0.05). The thickness of adenoids, palate height, palate length, and tongue length in the hypertrophy group exceeded that of the control group (p < 0.05). To conclude, adenoid hypertrophy was associated with craniofacial features such as a convex facial profile, a narrowed nasopharyngeal airway, an elongated and heightened palate, a lengthened tongue or a lower tongue position. These findings emphasize the importance of early intervention for children with adenoid hypertrophy to mitigate potential adverse effects on maxillofacial development.
