The therapeutic use of exosomes in children with adenoid hypertrophy accompanied by otitis media with effusion (AHOME): a protocol study

BackgroundThe adenoids act as a reservoir of bacterial pathogens and immune molecules, and they are significantly involved in children with otitis media with effusion (OME). As an essential carrier of intercellular substance transfer and signal transduction, exosomes with different biological functions can be secreted by various types of cells. There remains significant uncertainty regarding the clinical relevance of exosomes to OME, especially in its pathophysiologic development. In this study, we will seek to determine the biological functions of exosomes in children with adenoid hypertrophy accompanied by OME (AHOME).MethodsThe diagnostic criteria for OME in children aged 4–10 years include a disease duration of at least 3 months, type B or C acoustic immittance, and varying degrees of conductive hearing loss. Adenoidal hypertrophy is diagnosed when nasal endoscopy shows at least 60% adenoidal occlusion in the nostrils or when nasopharyngeal lateral X-ray shows A/N > 0.6. Children who meet the indications for adenoidectomy surgery undergo adenoidectomy. Peripheral blood, nasopharyngeal swab, and adenoid tissue will be collected from patients, and the exosomes will be isolated from the samples. Following the initial collection, patients will undergo adenoidectomy and peripheral blood and nasopharyngeal swabs will be collected again after 3 months.Expected resultsThis study aims to identify differences in exosomes from preoperative adenoid tissue and peripheral blood samples between children with AHOME and those with adenoid hypertrophy alone. Additionally, it seeks to determine changes in microbial diversity in adenoid tissue between these groups.ConclusionsThe findings are expected to provide new insights into the diagnosis and treatment of OME, to identify novel biomarkers, and to enhance our understanding of the pathophysiology of OME, potentially leading to the development of innovative diagnostic and therapeutic approaches.

The Administration of Steroids and its Impact on Caspase-3 Expression in Pediatric Adenoid Hypertrophy.

Adenoid hypertrophy is a prevalent pediatric condition, often necessitating surgical intervention. Intranasal steroid administration shows promise as a conservative treatment, particularly by inducing apoptosis in adenoidal cells, leading to a reduction in adenoid size and inflammation. This study aims to characterize the expression profile of caspase-3 as an apoptotic inducer protein in inflammatory and epithelial adenoid tissues and explore its association with steroid administration. We performed immunohistochemical staining for caspase-3 proteins in adenoid tissues obtained from 51 pediatric patients aged between 2.5 and 12 years (mean age: 6.09 ± 2.1 years) who underwent adenoid surgery. A retrospective analysis of clinical data was conducted, categorizing participants into steroid treatment receivers (n = 25) and non-receivers (n = 26). Subsequently, the lymphoid inflammatory tissue and epithelial tissue from the adenoid were compared in terms of caspase-3 protein expression, and associated clinical variables were assessed. Immunohistochemical analysis revealed significant caspase-3 expression in inflammatory tissues. The expression levels were scored, and no significant correlation was observed between inflammation and epithelium based on caspase-3 expression (correlation coefficient = 0.143; p > 0.05). Furthermore, demographic and clinical characteristics did not show a statistically significant difference in caspase-3 expression levels. Caspase-3 expression was significant in inflammatory adenoid tissue, but it showed no association with nasal steroid administration.

Changes in Stemness Properties of Human Adenoid-Derived Mesenchymal Stem Cells by in Vitro Aging

Mesenchymal stem cells (MSCs) have significant therapeutic potential in gene therapy. In vitro replicative senescence causes slow proliferation capacity of MSCs and changes in stem cell properties. In this study, the stem cell properties and proliferation potential of MSCs obtained from adenoid tissue, a new source of MSC, were investigated after long-term in vitro replicative senescence. Adenoid-derived MSCs (A-MSCs) were cultured up to passage 20 and were analyzed for cell morphology, proliferative capacity, differentiation potential and surface marker expression. In addition, the expression profile of cell cycle, apoptosis and senescence-related genes were evaluated. After in vitro replicative senescence, A-MSCs did not show significant morphological differences. The proliferation potential of A-MSCs was rapid up to passage 16, and a reduction in the proliferation potential of senescent cells in vitro was observed depending on the passage number. The differentiation potential of late-passage A-MSCs was also reduced compared to early-passage cells. A-MSCs also provided significant closure at the 8th hour in early passages in terms of closure of the scratch area, while late passage A-MSCs exhibited a similar closure profile at the 24th hour. In conclusion, A-MSCs have significant potential for clinical use due to the sustainability of MSC properties and their ability to proliferate and migrate with long-term culture.

Correlation of the Size of Adenoids With Impedance Audiometry Findings.

Introduction Adenoid tissue is part of the first line of immunity of the upper aero-digestive tract. It is located in the postero-superior wall of the nasopharynx behind the choana.Adenoid hypertrophy, a common childhood disorder, significantly contributes to the pathogenesis of otitis media with effusion (OME), which is the leading cause of hearing impairment in young children. This condition can result in delayed speech, poor academic performance, and language development issues. Assessing the size of the adenoids and their correlation with OME is crucial, as undiagnosed cases can lead to complications such as atelectasis of the tympanic membrane and cholesteatoma. Clinical examination of the nose alone is often insufficient, and children do not cooperate for nasal endoscopy. Therefore, a lateral radiograph of the skull is considered the most reliable method for assessing the adenoid size. The size of the adenoids can affect Eustachian tube patency, which is reflected in the results of impedance audiometry. This study aimed to correlate the size of adenoids with impedance audiometry findings. Methods This cross-sectional observational study was conducted in the Department of Otorhinolaryngology of a tertiary care hospital from October 1, 2022, to March 31, 2024. A sample size of 50 patients was taken for the study. The inclusion criterion of selection of the patients included patients aged 3 to 15 years, who suffered from recurrent attacks of upper respiratory tract infections,particularly those with adenoid facies confirmed by X-ray with a non-perforated tympanic membrane. Exclusion criteria encompassed patients below 3 or above 15 years, and those with acute or chronic suppurative otitis media, craniofacial anomalies, or nasal pathologies like polyps.Adenoids were graded using X-ray imaging of the nasopharynx, and correlations between the adenoid size and impedance audiometry findings, such as middle ear pressure and compliance, were analyzed. Results The study assessed the relationship between the adenoid size and impedance audiometry findings, focusing on middle ear pressure and compliance, as well as the occurrence of OME. The results indicated a significant decline in middle ear pressure with increasing adenoid grades. Specifically, adenoid grade 1 had an average pressure of -3.50 daPa, while grade 4 had the lowest average pressure at -119.72 daPa. This trend was statistically significant with a p-value of 0.00042. Similarly, compliance values also decreased with higher adenoid grades. Grade 1 had an average compliance of 0.64 ml, whereas grade 4 had the lowest average compliance at 0.28 ml. This relationship was statistically significant, as indicated by a p-value of 0.0048. Additionally, the analysis showed that a significant majority of patients with enlarged adenoids also presented with OME, highlighting a strong association between adenoid hypertrophy and this condition. Conclusion The study concluded that larger adenoids wereassociated with lower middle ear pressure and reduced compliance. Additionally, a significant majority of patients with enlarged adenoids also had OME. This underscores the importance of evaluating adenoid hypertrophy in the context of OME due to its potential impact on childhood hearing and development.

The role of adenoid immune phenotype in polysensitized children with allergic rhinitis and adenoid hypertrophy.

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. 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. 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. 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.

Comparison of classical method and microdebrider technique for adenoidectomy in pediatric patients with obstructive sleep apnea.

The aim of this study was to evaluate the safety and efficacy of microdebrider adenoidectomy on sleep-disordered breathing among pediatric patients with OSA. In the microdebrider group (Group I), there were 30 Japanese OSA patients consisting of 26 boys and 4 girls. For comparison, we had 15 children (13 boys and 2 girls) who underwent classical adenoidectomy (Group II). Patients in Group I were selected from a pool of 95 pediatric Japanese OSA patients and were matched by age, preoperative AHI, and Kaup index with those in Group II.Parameters such as the amount of residual adenoid tissue, bleeding, duration of the procedure, and sleep-related metrics were compared between the two groups. A significant improvement in postoperative AHI was observed in Group I (p<0.05). The prevalence of AHI <1 was significantly higher in Group I compared with Group II (p<0.05). Additionally, the amount of postoperative residual adenoid was significantly less in Group I (3/30 of Grade 3 and 4 adenoid size) than in Group II (7/15, p<0.05). Furthermore, a reduction in postoperative AHI was proportionally associated with a decrease in residual adenoid. The newly developed microdebrider adenoidectomy technique for pediatric OSA patients with adenotonsillar hypertrophy demonstrated greater accuracy and efficacy in ameliorating sleep apnea symptoms compared with the standard adenoidectomy approach.

A Case of a Eustachian Tube Hairy Polyp Misdiagnosed as an Adenoid Residual in a Child.

Hairy polyps, considered a highly unusual congenital anomaly of the pharynx, are believed by many scholars to arise from the ectoderm and mesoderm during the embryonic stage. These growths often have a pear or sausage shape, are pedunculated, and their size ranges between 0.5 and 6 cm. They are typically grayish white or pink in color. This article discusses a 12-year-old female who had a growth at the Eustachian tube's entrance on the left side of the nasopharyngeal wall, as identified by a computed tomography scan of the neck soft tissue; it was suspected to be a hairy polyp originating from the left Eustachian tube. The diagnosis of a hairy polyp was confirmed through pathology. The hairy polyp at the Eustachian tube, in this case, showed an irregular form with a wide base, making it look similar to an adenoid; thus, increasing the risk of it being misdiagnosed as residual adenoid tissue.

Comparison of classical, coblation, and combined adenoidectomy techniques in paediatric patients: a single-blind, prospective study

Background and objectivesAdenoidectomy is one of the most commonly performed surgeries in pediatric otolaryngological practice. This prospective study compared three different adenoidectomy techniques' intra-operative and postoperative outcomes in pediatric patients. The techniques evaluated were classical (blind curettage), coblation, and a combined approach.Materials and methodsNinety pediatric patients undergoing adenoidectomy were enrolled in the study. The patients were divided into three groups based on the technique used: Group A, classical adenoidectomy (blind curettage); Group B, coblation adenoidectomy and Group C, combined (blind curettage + coblation) adenoidectomy. The intra-operative time, degree of bleeding, and complications during and after the operations were recorded.ResultsGroup A had a significantly shorter operative time than the other groups. However, there was no significant difference in the mean operative time between Groups B and C. The mean amount of intra-operative bleeding differed significantly among the groups. Group B had significantly less bleeding than Group A or Group C. The amount of bleeding also differed significantly between Groups A and C. The postoperative pain scores did not differ significantly among the groups. While complications were infrequent in all groups, Group C did not exhibit a higher complication rate than Groups A and B. The absence of residual or recurrent adenoid tissue in any of the groups during long-term follow-up examinations highlights the effectiveness of all three adenoidectomy techniques in preventing adenoid regrowth.ConclusionsThe combined approach, which was one of the techniques studied, demonstrated an intermediate profile in terms of operative time and intra-operative bleeding compared to the classical and coblation techniques. These findings suggest that this combined approach may be a feasible option for adenoidectomy in pediatric patients, considering its similar low incidence of postoperative complications.

Possible role of endoplasmic reticulum stress in the pathogenesis of chronic adenoiditis and adenoid hypertrophy: A prospective, parallel-group study.

Adenoid tissue is a first-line host defense secondary lymphoid organ, especially in childhood. The endoplasmic reticulum (ER) is required to maintain balanced cellular activity. With impaired ER functions, protein accumulation occurs, resulting in ER stress, which plays a role in the etiopathogenesis of many diseases. We aimed to investigate the relationship between ER stress and adenoid tissue disorders, thereby elucidating the mechanisms of immunity-related diseases. Fifty-four pediatric patients (>3 years old) who underwent adenoidectomy for chronic adenoiditis (CA) or adenoid hypertrophy (AH) were enrolled in this prospective, parallel-group clinical study. Adenoids were divided into two groups (CA or AH) based on their size and evaluated for ER stress pathway and apoptosis pathway markers by Real-time PCR and Western blot analysis. ER stress pathway markers significantly differed between the CA and AH groups. Children with CA had higher ER stress marker levels than the AH group (p < .001 for ATF-4, ATF-6, and GRP78, and p < .05 for EDEM1, CHOP, EIF2AK3, ERNI, and GRP94). Apoptosis pathway marker levels (BAX and BCL-2) were not different between groups. ER stress contributes to the etiopathogenesis of adenoid tissue diseases and the pathogenesis of adenoid tissue disorders, which are part of the immune response. These results may guide the development of new and alternative treatments for immune system disorders.

Correlation of patient reported outcome measures with endoscopic findings in pediatric chronic adenoiditis and chronic rhinosinusitis

BackgroundStudies in adult chronic rhinosinusitis (CRS) showed poor correlation between patient reported outcome measures (PROMs) and objective findings. Our goal is to study the correlation between the sinus and nasal quality of life (SN-5) and the 22-items sinonasal outcome test (SNOT-22) surveys with endoscopy findings in children with chronic adenoiditis (CA) and CRS. MethodsCross-sectional study of all pediatric patients (age 2–18) presenting for CA or CRS was performed. Patients and caregivers were asked to fill the SN-5 and SNOT-22 questionnaires at initial and follow up visits. Demographics and comorbidities were collected. Objective findings included endoscopy Modified Lund-Kennedy (MLK) scores and adenoid tissue size. Results124 children were included, with mean age of 9.9 years (SD = 4.8) and 46.8% female. 36.3% had allergic rhinitis, 23.4% had asthma, and 4% had obstructive sleep apnea. Moderate correlation was found between the rhinologic domain of SNOT-22 and MLK scores (r = 0.36, p = 0.001) and between SN5 scores and adenoid size in all patients (r = 0.39, p < 0.001). SNOT-22 scores showed moderate correlation with adenoid size (r = 0.42, p < 0.001) more specifically in CA patients (r = 0.54, p < 0.001). The correlation of SN5 and MLK scores were higher in children with allergic rhinitis or asthma. The correlation between SN5 and adenoid size was lower in children with allergic rhinitis or asthma. ConclusionThere is discrepancy between the subjective measures and the objective findings in children with CA or CRS. The physical exam findings may not reflect the effect of CRS on the quality of life of children.

Mucosa-Associated Lymphoid Tissue Surgeries as a Possible Risk for Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.

Inflammatory bowel disease (IBD) is a group of chronic inflammatory gastrointestinal disorders that are caused by genetic susceptibility and environmental factors and affects a significant portion of the global population. The gut-associated lymphoid tissue (GALT) is known to play a crucial role in immune modulation and maintaining gut microbiota balance. Dysbiosis in the latter has a known link to IBD. Therefore, the increasing prevalence of adenoidectomy in children should be explored for its potential association with IBD. The objective of this paper was to assess the association between adenoid tissue removal and the risk of developing Crohn's disease (CD) and ulcerative colitis (UC). We conducted a pooled meta-analysis to evaluate the extended clinical outcomes in patients who underwent appendicectomy and tonsillectomy compared to those who did not. Our approach involved systematically searching the PubMed database for relevant observational studies written in English. We followed the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines to collect data from various time periods, and to address the diversity in study results; we employed a random-effects analysis that considered heterogeneity. For outcomes, odds ratios (ORs) were pooled using a random-effects model. Seven studies, out of a total of 114,537, met our inclusion criteria. Our meta-analysis revealed a significant association between appendicectomy and CD (OR: 1.57; 95% confidence interval (CI): 1.01 - 2.43; heterogeneity I2 = 93%). Similarly, we found a significant association between tonsillectomy and CD (OR: 1.93; 95% CI: 0.96 - 3.89; I2 = 62%). However, no significant association was observed between appendicectomy and UC (OR: 0.60; 95% CI: 0.24 - 1.47; I2 = 96%), while a modest association was found between tonsillectomy and UC (OR: 1.24; 95% CI: 1.18 - 1.30; I2 = 0%). In summary, we found that the trend of appendicectomy is linked to higher odds of CD, and tonsillectomy is more likely associated with increased odds for both CD and UC, with a risk of bias present.

Assessment of the relationship between oral health and adenoid hypertrophy in children aged 8 to 15 years

Background: The oral health of children is adversely affected by mouth breathing. One of the main reasons for mouth breathing in children is adenoid hypertrophy. Consequently, this study aimed to assess the relationship between oral health and adenoid hypertrophy among children aged 8–15 years in the city of Babol. Methods: This case-control study was conducted on 100 children. The case group included 50 children with adenoid hypertrophy. An Ear, Nose, and Throat (ENT) specialist examined the children clinically and referred them to the oral and maxillofacial radiology clinic. The study control group included 50 healthy children. To assess the size of the adenoidal tissues and the dimensions of the upper airways, we assessed the linear cephalometric measurement Ptm-ad2 . The evaluations consisted of the decayed, missing, and filled teeth (DMFT and dmft for permanent and primary teeth, respectively) index, mean periodontal pocket depth, plaque index (PI), and papillary marginal attached (PMA) index. Results: Fifty samples had adenoid hypertrophy. The prevalence of dental caries was significantly higher in children with adenoid hypertrophy compared to healthy children (DMFT was 4.10±2.09 and 2.06±0.97, and dmft was 3.52±3.34 and 1.48±1.24, in the case and control groups, respectively). Furthermore, the periodontal indices of the case group were significantly greater than those of the control group (periodontal pocket depth was 2.93±0.35 and 1.98±0.23, PI was 2.73±0.26 and 1.13±0.29, and the PMA index was 5.71±0.82 and 2.55±0.48, in the case and control groups, respectively). Conclusion: In the case group, there was a statistically higher prevalence of dental caries and gingival inflammation than in the control group. Therefore, periodical dental visits and preventive dental procedures are recommended for children with adenoid hypertrophy.

COMPARATIVE STUDY OF VARIOUS TECHNIQUES TONSILLECTOMY

Objective: The purpose of the study was to compare intraoperative factors and postoperative outcomes between the image-guided acute dissection technique and the endoscopic image-guided acute dissection technique. Material and methods: The study was conducted in 153 patients (81 men and 72 women, average age 26.4 years) who underwent tonsillectomy (2018-2023). Patients were randomly assigned 2 group 52% percent of patients(group1) underwent tonsillectomy with acute dissection technique under visual control, and 48% of patients (group 2) underwent tonsillectomy with acute dissection technique under endoscopic visualization using a 4.0 mm 0° endoscope (Karl Storz, Tuttlingen, Germany). Indications for tonsillectomy were hypertrophy of the tonsils in 82 patients, recurrent tonsillitis in 23 patients and focal infection of the tonsils in 48 patients. Tonsillectomy was performed under general anesthesia using an oral speculum specifically designed for tonsillectomy. All patients were assessed and compared for postoperative pain, bleeding, recurrence, or tonsil tissue growth in the immediate and late postoperative period. The removed adenoid is sent for histology. Clinical diagnosis: Chronic decompensated tonsillitis. Pathohistological diagnosis: Within the limits of the examined material, the histological picture corresponds to chronic tonsillitis, hypertrophy of nasopharyngeal adenoid tissue. Results: There were no serious intra- or postoperative complications. Bleeding points were identified in 47 patients (31 patients group1 and 16 patients group 2). The source of bleeding was observed in the central deep part of the adenoids - in 18 patients, in the lateral parts of the adenoids - in 16 patients, adenoids on both sides in 13. Remnants of adenoid tissue were found in 23 patients, (17 patients group 1 and 6 patients group 2). Remnants of adenoid tissue were removed using bipolar diathermy under image guidance. The operation time for endoscopic tonsillectomy is shorter than for traditional procedures. Conclusions: The visibility provided Tonsillectomy by endoscopic techniques improves the ease and precision of surgery. Clinical significance determines the need for further testing of already proposed means and methods.

Increasing incidence of mastoidectomies in children : Result of reduced antibiotic therapy or late COVID-19 sequela?

An increasing number of pediatric patients with mastoiditis and aconsequent increase in mastoidectomy rates was noted in 2022 and 2023. This study aimed to analyze the increase in the number of children presenting with mastoiditis and subsequent mastoidectomy, to assess correlations with prior antibiotic treatment or COVID-19 infection, and to provide an overview of involved pathogens, treatment, and disease course. Aretrospective analysis of all patients with mastoidectomy since 2012 was conducted. Data collected comprised type and duration symptoms, prior antibiotic therapy, diagnostic tests and disease course, causal pathogens, length of hospitalization, and complications. Ahighly significant increase in mastoidectomies in children could be demonstrated from 2022. Neither the pathogens involved nor the course of disease or complications showed differences. An increase in the number of patients with prior outpatient antibiotic therapy could be shown. About ahalf of the patients becoming ill after fall 2022 had apositive history of COVID. Hyperplasia of adenoid tissue was afar less frequent causal mechanism than in the years before COVID. No clear correlation with reduced outpatient antibiotic therapy could be found. Whether there exists an association with prior COVID infection cannot be judged at this time, due to the high number of asymptomatic and therefore unknown COVID infections.

Analysis of clinical characteristics of children with adenoid hypertrophy and pharyngolaryngeal reflux

Objectives: To explore the clinical characteristics of children with adenoid hypertrophy (AH) and laryngopharyngeal reflux (LPR) by detecting the expression of pepsin in adenoids as a standard for AH with LPR. Methods: A total of 190 children who were admitted for surgical treatment due to AH were included in the study. The main clinical symptoms of the patients were recorded, and the degree of adenoid hypertrophy was evaluated. Before the surgery, Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) were used to evaluate the reflux symptoms. After the surgery, pepsin immunohistochemical staining was performed on the adenoid tissue, and according to the staining results, the patients were divided into study group (pepsin staining positive) and control group (pepsin staining negative). SPSS 19.0 software was used for statistical analysis. Quantitative data conforming to normal distribution between the two groups were tested by two-independent sample t test, and quantitative data with skewed distribution were tested by Mann-Whitney U test. Results: The positive rate of pepsin staining in the 190 AH patients was 78.4% (149/190). The study group had higher levels of preoperative symptoms such as erythema and/or congestion of the pharynx(2.1±0.7 vs. 1.8±0.6,t=2.23), vocal cord edema[1.0(0, 1.0) vs. 1.0(0, 1.0), Z=2.00], diffuse laryngeal edema[0(0, 1.0) vs. 0(0, 0), Z=2.48], posterior commissure hypertrophy[(1.4±0.6 vs. 1.1±0.5), t=2.63], and a higher total score on the RFS scale than the control group(6.2±2.7 vs. 5.0±2.6, t=2.47), with statistical differences (P<0.05). The sensitivity and specificity of RFS score in diagnosing AH with LPR were 24.8% and 80.5%, respectively. When RFS>5 was used as the positive threshold, the sensitivity and specificity of RFS score in diagnosing AH with LPR were 61.1% and 58.5%, respectively. There was a statistical difference in the number of positive cases of RFS score between the study group and the control group(91 vs. 17,χ2=5.04,P=0.032). Conclusions: LPR is common in AH children. Children with AH and LPR have specific performance in electronic laryngoscopy, such as erythema with edema in the pharynx, posterior commissure hypertrophy, and vocal cord edema.

Effectiveness of Adenoidectomy as a Standalone Procedure in Improving the Quality of Life of Children with Obstructive Sleep Apnea.

Adenoid hypertrophy (AH) and its sequel like nasal obstruction, obstructive sleep apnoea (OSA), recurrent rhinitis and middle ear disorders are common diseases of pediatric age group, forming the major bulk of pediatric outpatient visits. The recommended approach to treating OSA in children is through adenotonsillectomy. Adenoidectomy is the surgical procedure of removal of hypertrophied adenoid tissues, which is the most common surgery performed by Ear, Nose, and Throat (ENT) surgeons. Given that adenoidectomy alone might lead to reduced instances of adverse outcomes, decreased risk of complications, and lower expenses, our objective was to explore the viability and suitability of adenoidectomy as a standalone treatment for pediatric OSA and to learn the significant effect of adenoidectomy on the quality of life (QOL) of children. Multicentric prospective study conducted in Department of ENT, Head and Neck Oncosurgery, Smita Memorial Hospital, Thodupuzha & Department of ENT, Head and Neck surgery, MCS Hospital, Muvattupuzha, Kerala, India from June 2022 to June 2023. Children between the age group of 5-10 years, who underwent adenoidectomy during the study period, satisfying the inclusion criteria were subjected for the study. Adenoidectomy was done for them using endoscope assisted coblation technique. Postoperative improvement in symptoms and change in quality of life were analyzed using obstructive sleep disorders-6 (OSD-6) questionnaire at the end of 3 months follow up. The surgeon observed a statistically significant improvement in all domains of OSD-6; and there by improvement in QOL in all patients, who underwent adenoidectomy in a course of three months. Adenoid hypertrophy is the most common cause of nasal obstruction in pediatric population and is creating a significant negative impact on the quality of life of children. Adenoidectomy is a safe and simple procedure which can provide significant improvement in quality of life of kids. Adenoidectomy in isolation could be a valid and recommended surgical choice for selected population of children displaying symptoms of pediatric OSA.

Adenoid Hypertrophy Managed With Artemisia Cina Dilution: A Study of Two Cases

Adenoid hypertrophy, is the enlargement of adenoid tissues in the nasopharynx, a common concern among children and often exhibits with nasal congestion, mouth breathing, snoring, and sleep disturbances. Spontaneous healing of enlarged adenoid is common in adolescents and adults, however, in this case study, we present two instances of pediatric patients who demonstrated adenoid-related health issues. After a thorough evaluation, and based on the principle of symptom similarity Artemisia cina was prescribed; this treatment continued for three consecutive weeks, and a follow-up lateral x-ray of nasopharynx was obtained one more week later. The use of homeopathic preparation of Artemisia cina appeared to ease their symptoms. This outcome suggests that Artemisia cina may hold promise as a homeopathic option for managing adenoid-related concerns in pediatric patients. However, we acknowledge that further research and a larger sample size are necessary to establish the usefulness of this approach. Bioresearch Commu. 10(1): 1449-1452, 2024 (January)

Inflammatory endotypes of adenoidal hypertrophy based on a cluster analysis of biomarkers

ObjectiveTo identify adenoid inflammatory endotypes based on inflammatory markers, match endotypes to phenotypes, and predict endotypes. MethodsThis cross-sectional study included 72 children with adenoid hypertrophy. Thirteen inflammatory markers and total immunoglobulin E (TIgE) in adenoid tissue were analyzed using Luminex and enzyme-linked immunosorbent assay (ELISA) for performing cluster analysis. Correlation analysis was used to examine the characteristics of each cluster. Receiver operating characteristic (ROC) curve analysis was performed to screen for preoperative characteristic data with predictive value for adenoid inflammation endotype. ResultsThe patients were divided into four clusters. Cluster 1 exhibited non-type 2 signatures with low inflammatory marker concentrations, except for the highest expression of Th1-related cytokines. Cluster 2 showed a non-type 2 endotype with the highest concentration of interleukin (IL)-17A and IL-22. Cluster 3 exhibited moderate type 2 inflammation, with the highest concentration of neutrophil factors. Cluster 4 demonstrated significant type 2 inflammation and moderate neutrophil levels. The proportions of AR and serum TIgE levels increased from clusters 1 to 4, and there was a gradual increase in the prevalence of chronic sinusitis from low to high neutrophilic inflammation. The area under the ROC curve for serum TIgE was higher than those for combined or other separate preoperative characteristics for predicting non-type 2 and type 2 inflammation in the adenoid tissue. ConclusionsThe evaluation of cytokines in adenoid tissue revealed four endotypes. Serum TIgE level was an important indicator of the endotype of adenoid inflammation. Identification of adenoid inflammatory endotypes can facilitate targeted treatment decisions.

Քթի միջնապատի ուղղումը մանկական տարիքում

Pediatric septoplasty has been one of the most controversial topics discussed among ENT and plastic surgeons: The aim of the study is to evaluate the outcome of septoplasty several years after performing it during the pediatric age, and if it contributes subsequently to the recurrent deformation of the nasal septum or the external nasal structure. The study also touches on the notion of whether adenoidectomy and/or inferior turbinate reduction without correcting the deviated nasal septum are enough to restore nasal breathing. The study included 56 children aged from 5 to 15 years. All the participating patients were diagnosed with deviated nasal septum, but were divided into 2 groups according to the surgical techniques performed. The first group included 24 patients and their difficult nasal breathing was conditioned by deviated nasal septum, adenoid tissue hypertrophy with 5 of the children also having inferior turbinate hypertrophy. However, they all underwent adenoidectomy and inferior turbinate radiofrequency reduction only. The second group included 32 patients with difficult nasal breathing caused by deviated nasal septum, adenoid tissue hypertrophy with 11 children also having inferior turbinate hypertrophy. All the patients in this group underwent septoplasty, adenoidectomy and where indicated inferior turbinate radiofrequency reduction. All the 24 patients included in the first group exhibited improvement in nasal breathing index from 231,6 ± 9,26 cm3 up to 427,0±5,6 cm3 (p&lt;0,05). As for the snoring loudness scale, there was improvement from 2,6±0,1 to 1,3±0,1 (p&lt;0,05), but without complete disappearance. Patients included in the second group which totalled 32 in number saw improvement in nasal breathing index from 228,5±7,29 cm3 to 592,9±5,29 cm3 (p&lt;0,05) while snoring loudness scale improved from 2,47±0,09 to 0,09±0,05 (p&lt;0,05).

Correlation Between Nasal Allergy and the Number of Eosinophils in Adenoid Tissue.

To study adenoid tissue eosinophilia in allergic rhinitis. A single-centre clinical case-control prospective study with 66 subjects enrolled for the study after taking written informed consent from all the participants. All patients underwent adenoidectomy with histopathological evaluation of adenoid tissue samples for eosinophils. 36 patients (cases) with Symptoms for Allergic Rhinitis (SFAR) score indicative of allergic rhinitis. 30 patients (control) with SFAR scores not indicative of allergic rhinitis. All patients were evaluated for serum absolute eosinophil count and total serum immunoglobulin E (Ig-E). There was a significant relationship between allergic rhinitis and serum Ig-E levels using the Kruskal-Wallis rank sum test amongst case and control groups with a p-value of 0.031. Pathologically examined slides of adenoid tissue eosinophil count per 10 random high power fields in these patients showed significant results with a p-value of 0.002432, via the Kruskal-Wallis rank sum test. Statistical analysis, shows that adenoid tissue eosinophil count and serum Ig-E levels can somewhat predict the presence of clinical features of allergic rhinitis. Based on several similar studies with similar results, allergic rhinitis can be gauged with adenoid tissue histopathology and routine evaluation should be considered as a standard of care.
