Resumen: Introducción: Estudios recientes señalan un aumento de la prevalencia de Haemophilus influenzae y una disminución de Streptococcus pneumoniae entre las bacterias causantes de otitis media aguda (OMA). El objetivo del estudio es conocer la distribución de microorganismos patógenos identificados en Urgencias en los menores de 14 años con OMA y su patrón de resistencias. Pacientes y métodos: Estudio retrospectivo, analítico y unicéntrico incluyendo pacientes menores de 14 años diagnosticados de OMA en los que se recogió un cultivo de secreción ótica en el servicio de urgencias pediátricas de un hospital terciario entre 2013 y 2021. Resultados: Durante el periodo de estudio se registraron 14.684 episodios con diagnóstico de OMA, recogiéndose en 768 cultivo de secreción ótica. La mediana de edad fue de 2 años, el 57% varones y el 70% habían presentado al menos una OMA previa. Los patógenos más frecuentemente aislados fueron: Haemophilus influenzae, 188 (24,5%; de ellos, 15,5% resistentes a ampicilina); Streptococcus pyogenes, 86 (11,2%); Staphylococcus aureus, 82 (10,7%); Streptococcus pneumoniae, 54 (6,9%; de ellos, 9,4% con resistencia intermedia a penicilina); Pseudomonas aeruginosa, 42 (5,5%) y Moraxella catarrhalis, 11 (1,4%). En el 34,9% no se aislaron patógenos. Conclusiones: Haemophilus influenzae es la primera causa de OMA en menores de 14 años. Este hecho, junto a la baja tasa de aislamientos y resistencia a penicilina de Streptococcus pneumoniae, cuestiona la idoneidad de la amoxicilina a dosis elevadas como tratamiento antibiótico empírico de la OMA. Abstract: Introduction: Recent studies show an increase in the prevalence of Haemophilus influenzae and a decrease in Streptococcus pneumoniae among the bacteria that cause acute otitis media (AOM). The objective of our study was to analyse the distribution of pathogens identified in children aged less than 14 years presenting to the emergency department with AOM and their patterns of antimicrobial resistance. Patients and methods: Single centre retrospective, analytical study in patients aged less than 14 years with a diagnosis of AOM in whom an ear drainage sample was collected for culture in the paediatric emergency department of a tertiary care hospital between 2013 and 2021. Results: During the study period, there were 14,684 documented care episodes corresponding to children with a diagnosis of AOM. An ear drainage culture was performed in 768 of those episodes. The median age of the patients was 2 years, 57% were male and 70% had a previous history of AOM. The most frequently isolated pathogens were: Haemophilus influenzae (n = 188 [24.5%]; 15.5% of them resistant to ampicillin), Streptococcus pyogenes (n = 86 [11.2%]), Staphylococcus aureus (n = 82 [10.7%]), Streptococcus pneumoniae (n = 54 [6.9%]; 9.4% with intermediate resistance to penicillin), Pseudomonas aeruginosa (n = 42 [5.5%]) and Moraxella catarrhalis (n = 11 [1.4%]). No pathogen was isolated in 34.9% of cases. Conclusions: Haemophilus influenzae is the leading cause of AOM in children aged less than 14 years. This, combined with the low frequency of isolation and penicillin resistance of Streptococcus pneumoniae, calls into question the appropriateness of high-dose amoxicillin for empiric treatment of AOM

Rationale: Acute otitis media is a common disease in early childhood, and is usually caused by Streptococcus pneumoniae (S. pneumoniae). Acute mastoiditis is a complication of acute otitis media and can involve not only the mucoperiosteum of the middle ear but can also spread to the periosteum by destroying the mastoid bone (acute coalescent mastoiditis). In addition, the infection can extend through the surrounding bones or the emissary veins beyond the mastoid's air cells, leading to subperiosteal abscesses. Patient's Concern: A 16-month-old female patient was hospitalized due to the purulent discharge of the left ear and the symptoms of right mastoiditis (swelling and redness of the skin). Diagnosis: Bilateral acute coalescent mastoiditis caused by S. pneumoniae infection. The computer tomography revealed bilateral bone destruction of the mastoid and abscesses found behind the auricle on both sides. Interventions: The patient underwent intravenous antibiotic therapy and surgical treatment. Outcomes: The patient was discharged 14 days after hospitalization with an improved condition. Lessons: Improperly treated acute coalescent mastoiditis can lead to extracranial and intracranial complications, sometimes serious and even life-threatening. Complications are prevalent in children under 2 years, in whom the disease progresses more rapidly and severely. The vaccination with a 13-valent vaccine may not result in sufficient immunity against S. pneumoniae, a predominant pathogen in children affected by acute coalescent mastoiditis.

Abstract Background Watchful waiting management for acute otitis media (AOM), where an antibiotic is used only if the child’s symptoms worsen or do not improve over the subsequent 2–3 days, is an effective approach to reduce antibiotic exposure for children with AOM. However, studies to compare the effectiveness of interventions to promote watchful waiting are lacking. The objective of this study is to compare the effectiveness and implementation outcomes of two pragmatic, patient-centered interventions designed to facilitate use of watchful waiting in clinical practice. Methods This will be a cluster-randomized trial utilizing a hybrid implementation-effectiveness design. Thirty-three primary care or urgent care clinics will be randomized to one of two interventions: a health systems-level intervention alone or a health systems-level intervention combined with use of a shared decision-making aid. The health systems-level intervention will include engagement of a clinician champion at each clinic, changes to electronic health record antibiotic orders to facilitate delayed antibiotic prescriptions as part of a watchful waiting strategy, quarterly feedback reports detailing clinicians’ use of watchful waiting individually and compared with peers, and virtual learning sessions for clinicians. The hybrid intervention will include the health systems-level intervention plus a shared decision-making aid designed to inform decision-making between parents and clinicians with best available evidence. The primary outcomes will be whether an antibiotic was ultimately taken by the child and parent satisfaction with their child’s care. We will explore the differences in implementation effectiveness by patient population served, clinic type, clinical setting, and organization. The fidelity, acceptability, and perceived appropriateness of the interventions among different clinician types, patient populations, and clinical settings will be compared. We will also conduct formative qualitative interviews and surveys with clinicians and administrators, focus groups and surveys of parents of patients with AOM, and engagement of two stakeholder advisory councils to further inform the interventions. Discussion This study will compare the effectiveness of two pragmatic interventions to promote use of watchful waiting for children with AOM to reduce antibiotic exposure and increase parent satisfaction, thus informing national antibiotic stewardship policy development.

Background Antimicrobial resistance is a worldwide threat, exacerbated by inappropriate prescribing. Most antibiotic prescribing occurs in primary care. Early-career GPs are important for the future of antibiotic prescribing and curbing antimicrobial resistance. Objectives To determine antibiotic prescribing patterns by early-career GPs for common acute infections. Methods A systematic literature search was conducted using PubMed, Embase and Scopus. Two authors independently screened abstracts and full texts for inclusion. Primary outcomes were antibiotic prescribing rates for common acute infections by GPs with experience of 10 years or less. Secondary outcomes were any associations between working experience and antibiotic prescribing. Results Of 1483 records retrieved, we identified 41 relevant studies. Early-career GPs were less likely to prescribe antibiotics compared with their more experienced colleagues (OR range 0.23–0.67). Their antibiotic prescribing rates for 'any respiratory condition' ranged from 14.6% to 52%, and for upper respiratory tract infections from 13.5% to 33%. Prescribing for acute bronchitis varied by country, from 15.9% in Sweden to 26% in the USA and 63%–73% in Australia. Condition-specific data for all other included acute infections, such as sinusitis and acute otitis media, were limited to the Australian context. Conclusions Early-career GPs prescribe fewer antibiotics than later-career GPs. However, there are still significant improvements to be made for common acute conditions, as their prescribing is higher than recommended benchmarks. Addressing antimicrobial resistance requires an ongoing worldwide effort and early-career GPs should be the target for long-term change. [ABSTRACT FROM AUTHOR]

Background Acutely ill children are at risk of unwarranted antibiotic prescribing. Data on the appropriateness of antibiotic prescriptions provide insights into potential tailored interventions to promote antibiotic stewardship. Objectives To examine factors associated with the inappropriateness of antibiotic prescriptions for acutely ill children presenting to ambulatory care in high-income countries. Methods On 8 September 2022, we systematically searched articles published since 2002 in MEDLINE, Embase, CENTRAL, Web of Science, and grey literature databases. We included studies with acutely ill children presenting to ambulatory care settings in high-income countries reporting on the appropriateness of antibiotic prescriptions. The quality of the studies was evaluated using the Appraisal tool for Cross-Sectional Studies and the Newcastle–Ottawa Scale. Pooled ORs were calculated using random-effects models. Meta-regression, sensitivity and subgroup analysis were also performed. Results We included 40 articles reporting on 30 different factors and their association with inappropriate antibiotic prescribing. 'Appropriateness' covered a wide range of definitions. The following factors were associated with increased inappropriate antibiotic prescribing: acute otitis media diagnosis [pooled OR (95% CI): 2.02 (0.54–7.48)], GP [pooled OR (95% CI) 1.38 (1.00–1.89)] and rural setting [pooled OR (95% CI) 1.47 (1.08–2.02)]. Older patient age and a respiratory tract infection diagnosis have a tendency to be positively associated with inappropriate antibiotic prescribing, but pooling of studies was not possible. Conclusions Prioritizing acute otitis media, GPs, rural areas, older children and respiratory tract infections within antimicrobial stewardship programmes plays a vital role in promoting responsible antibiotic prescribing. The implementation of a standardized definition of appropriateness is essential to evaluate such programmes. [ABSTRACT FROM AUTHOR]

Objectives: Acute mastoiditis (AM) and its associated intra and extracranial complications are rare complications of acute otitis media. However, they are associated with a high morbidity. The management of AM with complications carries significant variations in approach. We aimed to evaluate the presentation of children with AM with complications to a tertiary referral centre in the United Kingdom and describe evolution of the treatment approaches. Methods: We undertook a retrospective chart review of all children admitted with AM to the University Hospitals of Leicester between 2013 and 2022. Results: Twenty‐seven children were included in this study: 7 patients had sigmoid sinus thrombosis (SST), 4 had an intracranial collection, 3 had cranial nerve palsy and 16 had a subperiosteal abscess (SPA); some patients had more than 1 complication. In this study, treatment of SPA with incision and drainage (I&D) and grommet insertion was effective, as all patients treated with grommet insertion and I&D recovered well and did not require a subsequent cortical mastoidectomy. All patients with SST received anticoagulation and intravenous (IV) antibiotics; surgical input consisted of grommet insertion alone and cortical mastoidectomy was not routinely performed in these patients. Conclusion: In our series, management of SPA with grommet insertion and drainage had good outcomes. SST management mainly consisted of IV antibiotics, anticoagulation and grommet insertion with good recovery. The evidence to guide the management of complications of mastoiditis is of poor quality and further research is needed to clarify the optimal management of these complications.

Introduction Acute otitis and sinusitis are common complications in patients with influenza and are responsible for increased hospitalization rates. Methods A five-year retrospective study (2018-2023) was conducted including all patients hospitalized for influenza (etiologic diagnosis by RT-PCR) to identify the incidence and characteristics of cases complicated with otitis and/or sinusitis. Cases associated with other viral co-infections were excluded from the analysis. Results We identified a cumulative rate of 20.6% (324 cases) of acute otitis (AO) and acute sinusitis (AS) among patients with influenza. Of these, 62.3% had AO, 28.1% AS, and 9.6% concomitant AO and AS. Cases of AO were predominant in the pediatric population (97.0%), while cases of AS were more common in adults (56.1%). Influenza A viruses were identified in 67.2% of patients. The infection with influenza B viruses increased the risk of acute congestive otitis media 2.1-fold (p=0.020), and influenza A viruses increased the risk of acute maxillary sinusitis 2.7-fold (p=0.029). Late presentation to the hospital, with a median of 4 days from the onset of influenza symptoms, was identified as a factor in the occurrence of AO and AS. Conclusions The risk of AO and AS is increased in patients with influenza, especially in the pediatric population and in late hospital presentations. These findings highlight the importance of proper monitoring and management of patients with influenza to prevent the development of complications, as well as the need to better understand the mechanisms whereby influenza viruses contribute to these secondary conditions.

Background Acute otitis media (AOM) is the most common reason children are prescribed antibiotics. Bacteria that produce beta-lactamase are an increasingly frequent cause of AOM and may be resistant to amoxicillin, the currently recommended treatment for AOM. We aimed to evaluate the clinical outcomes of children treated with amoxicillin for AOM and assessed whether outcomes vary by infecting pathogen or beta-lactamase production. Methods 205 children 6-35 months old diagnosed with AOM and prescribed amoxicillin were included. Bacterial culture and qualitative multiplex real-time polymerase chain reaction were performed on nasopharyngeal swabs collected at enrollment. Parents completed surveys assessing symptoms, antibiotic adherence, and potential adverse events. The primary outcome was treatment failure with amoxicillin. Secondary outcomes included recurrence, symptom improvement, resolution, and adverse drug events (ADE). Results 8 children (5.4%) experienced treatment failure and 14 (6.8%) had recurrence. By day 5, 152 (74.1%) children had symptom improvement and 97 (47.3%) had resolution. Parents reported ADE for 56 (27.3%) children. Among 149 children who did not take any amoxicillin before enrollment, 98 (65.8%) had one or more beta-lactamase-producing bacteria. Common bacterial otopathogens were Moraxella catarrhalis (79, 53.0%), Streptococcus pneumoniae (51, 34.2%), Haemophilus influenzae (30, 20.1%), and Staphylococcus aureus (21, 14.1%). Treatment failure did not differ between children that did (5, 5.1%) and did not (3, 5.9%) have beta-lactamase-producing otopathogens (p = .05). Conclusions Among children diagnosed with AOM treated with amoxicillin, treatment failure was uncommon and did not differ by pathogen or beta-lactamase production. These data support guidance recommending amoxicillin despite an increasing prevalence of beta-lactamase-producing bacteria. [ABSTRACT FROM AUTHOR]

Objectives: To explore the views of parents and carers regarding the management of acute otitis media in urban Aboriginal and Torres Strait Islander children who are at low risk of complications living in urban communities. Study design: Qualitative study; semi‐structured interviews and short telephone survey. Setting, participants: Interviews: purposive sample of parents and carers of urban Aboriginal and Torres Strait Islander children (18 months – 16 years old) screened in Aboriginal medical services in Queensland, New South Wales, and Canberra for the WATCH study, a randomised controlled trial that compared immediate antibiotic therapy with watchful waiting for Aboriginal and Torres Strait Islander children with acute otitis media. Survey: parents and carers recruited for the WATCH trial who had completed week two WATCH surveys. Results: We interviewed twenty‐two parents and carers, including ten who had declined participation in or whose children were ineligible for the WATCH trial. Some interviewees preferred antibiotics for managing acute otitis media, others preferred watchful waiting, expressing concerns about side effects and reduced efficacy with overuse of antibiotics. Factors that influenced this preference included the severity, duration, and recurrence of infection, and knowledge about management gained during the trial and from personal and often multigenerational experience of ear disease. Participants highlighted the importance of shared decision making by parents and carers and their doctors. Parents and carers of 165 of 262 WATCH participants completed telephone surveys (63%); 81 were undecided about whether antibiotics should always be used for treating acute otitis media. Open‐ended responses indicated that antibiotic use should be determined by clinical need, support for general practitioners' decisions, and the view that some general practitioners prescribed antibiotics too often. Conclusions: Parents and carers are key partners in managing acute otitis media in urban Aboriginal and Torres Strait Islander children. Our findings support shared decision making informed by the experience of parents and carers, which could also lead to reduced antibiotic use for managing acute otitis media. [ABSTRACT FROM AUTHOR]

Background: Acute otitis media (AOM) is a common issue among children, often requiring antibiotic treatment. It is crucial to explore methods for the rational use of antibiotics. This study aimed to assess the effectiveness of the watchful waiting approach in treating children aged 6 months to 18 years with mild to moderate AOM. Methods: This prospective quasi-experimental study was conducted on 100 children with mild to moderate AOM. All patients, except those in severe or critical conditions, were placed on the watchful waiting strategy. A follow-up was conducted after 48 - 72 hours. If symptoms had improved, the watchful waiting approach continued. If medication was necessary for various reasons, these reasons were documented. Subsequently, childrenwhocompleted the watchful waiting strategy were compared to thosewho received antibiotics. The collected data were analyzed using chi-square and t-tests in SPSS Statistics for Windows (version 16.0). Results: In this study, 59 patients (59%) were treated with the watchful waiting approach; nevertheless, 41 patients (41%) received antibiotics. The presence or absence of postnasal discharge showed a significant difference between the two groups (P = 0.001). No significant differences were observed between the two groups regarding fever (P = 0.066), enlarged tonsils (P = 0.740), snoring (P = 0.252), and bilateral involvement of the tympanic membrane (P = 0.313). Conclusions: Based on the results, the watchful waiting strategy is a cost-effective method for children aged over 6 months with mild to moderate symptoms, provided that parents cooperate fully. Clinicians should be cautious and consider alternative treatments if postnasal discharge is present, as it might indicate a higher likelihood of treatment failure with the watchful waiting approach.

Objectives: In this study, we propose a diagnostic model for automatic detection of otitis media based on combined input of otoscopy images and wideband tympanometry measurements. Methods: We present a neural network‐based model for the joint prediction of otitis media and diagnostic difficulty. We use the subclassifications acute otitis media and otitis media with effusion. The proposed approach is based on deep metric learning, and we compare this with the performance of a standard multi‐task network. Results: The proposed deep metric approach shows good performance on both tasks, and we show that the multi‐modal input increases the performance for both classification and difficulty estimation compared to the models trained on the modalities separately. An accuracy of 86.5% is achieved for the classification task, and a Kendall rank correlation coefficient of 0.45 is achieved for difficulty estimation, corresponding to a correct ranking of 72.6% of the cases. Conclusion: This study demonstrates the strengths of a multi‐modal diagnostic tool using both otoscopy images and wideband tympanometry measurements for the diagnosis of otitis media. Furthermore, we show that deep metric learning improves the performance of the models. [ABSTRACT FROM AUTHOR]

Chronic adenoiditis (CA) is generally sustained by some infectious foci mainly located within the nasopharynx or in the deep adenoidal pads and it is characterized by a complex interplay between bacterial species. The aim of this study was to assess the efficacy and safety of the topical nasal administration of a probiotic compound based on S. salivarius 24SMB and S. oralis 89a in children with CA in terms of reduction in: the number of acute adenoidal infections (primary outcome), and in the blockage of the nasopharynx space by hypertrophic adenoids (secondary outcome). A prospective, double-blind, 1:1 randomized controlled study was performed to test the effectiveness of a 90-day treatment with Rinogermina spray (DMD ITALIA s.r.l, Rome), 1 puff each nostril twice a day for 90 days, to nasal spray placebo in children with CA (in terms of number of acute exacerbations and blockage of nasopharynx space assessed after 90 days of treatment- T1, and 90 days later- T2). The final analysis was based on 152 children (males = 48.0%; mean age = 49.2 ± 14.1 months). Compared to the baseline, no significant differences in terms of number of acute exacerbations at T1 and T2 follow-up visits were detected in both groups. After treatment, a significant reduction in the blockage of nasopharynx space by hypertrophic adenoids (0.002 < p-value < 0.007) compared to the baseline was attested in the study group at T1 and T2, but not in the control group. Conclusions: Our findings document a positive effect of Rinogermina spray in achieving reduction in the blockage of nasopharynx space by hypertrophic adenoids, thus suggesting that its use into the integrated therapeutic management of children with CA could be of a certain utility. What is Known: • Chronic adenoiditis in children results from an imablance in baterial homeostasis at the nasophaynx, with impairment in respiratory microbiota. • The modulatory effect of target transnasal bacteriotheray by means of S. salivarius has been considered in children with chronic adenoiditis in children with recurrent acute otitis media with preliminary positive results. What is New: • This randomized controlled study, specifically designed on a cohrt of children with chronic adenoiditis, documents a certain effectiveness of the probiotic treatment in achieving a reduction in the grade of adenoidal hypertropy, compared to placebo.

This article discusses a study conducted at a hospital in Finland that examined the presence of respiratory viruses in children with acute otitis media (AOM), a common ear infection. The study found that AOM was most common in children with human metapneumovirus (hMPV) and respiratory syncytial virus (RSV) infections. However, the highest number of AOM cases overall was found in children with rhinovirus infection. The study suggests that preventing these respiratory viral infections could help reduce the occurrence of AOM in children. The study was supported by various funding sources and the authors have no conflicts of interest. [Extracted from the article]

Introduction Despite the introduction of effective pneumococcal conjugate vaccines (PCV), Streptococcus pneumoniae remains a major cause of acute otitis media (AOM) worldwide. New, higher valency vaccines that offer broader serotype coverage have been recently developed and others are in development. However, given the capsular serotypes expressed by pneumococci causing AOM, it is unclear to what extent differing or higher valency PCVs will provide additional protection. Areas Covered We conducted a systematic literature search of the MEDLINE database to identify articles published from January 2016 to September 2021 in 4 low and middle income and 10 high-income countries. We searched PubMed with terms: (Streptococcus pneumoniae) OR pneumococcal AND serotype AND (conjugate vaccine). We evaluated serotype distribution and the actual or projected coverage of pneumococcal serotypes by PCV10 (GlaxoSmithKline), PCV13 (Pfizer), PCV10SII (Serum Institute of India) PCV15 (Merck) and PCV20 (Pfizer). Expert Opinion Our review highlights the important epidemiological differences in serotype distribution and coverage by existing and higher valency vaccines to protect against AOM in children. These data provide support for further evaluation of serotype-independent vaccines for optimal control of pneumococcal AOM disease worldwide.

Acute otitis media (AOM) is one of the most common ENT diseases in children. In the antibiotic/post-antibiotic era, facial paralysis is a very rare complication of AOM (0.004–0.005%). Despite the rarity of this complication, it should be known by all physicians for proper therapeutic management to avoid serious sequelae. The aim of this review is to provide a management guide based on the current literature. Materials and Methods: Fifteen studies published between 2000 and 2022 were selected, including 120 patients (62 M/58 F) with an average age of 4.96 years old (range = 4 months–16 years; SD: 4.2). The paralysis frequently has a sudden onset and is of a severe grade (medium House–Brackmann (HB) score at onset: 4.68; SD: 0.5); however, it tends to have an almost complete recovery in most patients (88.49% HB 1 at follow-up). Results: Its first-line treatment must be based on the use of antibiotics (beta-lactam antibiotics as penicillins or cephalosporins). Corticosteroids should be used concomitantly for their anti-inflammatory and neuroprotective actions; however, there is no unanimity between authors about their application. Myringotomy, with or without ventilation tube insertion, is indicated in cases where the tympanic membrane is intact. Other kinds of surgery should be performed only in patients who have a worsening of their AOM symptoms or a worsening in HB score even with clinical treatment. Conclusions: The obtained data show that a conservative treatment can be sufficient for complete recovery in most patients, and it is preferred as the first-line therapy. Mastoidectomy should be performed only in patients with acute mastoiditis and without symptom improvement after a conservative approach. There are insufficient data in the current literature to provide clear selection criteria for patients who need to undergo mastoidectomy with facial nerve decompression. The choice of this treatment is based on an individual center expertise. Further studies are needed to clarify the role of corticosteroids and the role of facial nerve decompression in this clinical scenario.

Biofilms, aggregates of bacteria enclosed in a self-produced matrix, have been implicated in various pediatric respiratory infections, including acute otitis media (AOM), otitis media with effusion (OME), adenoiditis, protracted bacterial bronchitis, and pulmonary exacerbations in cystic fibrosis. These infections are prevalent in children and often associated with biofilm-producing pathogens, leading to recurrent and chronic conditions. Biofilms reduce antibiotic efficacy, contributing to treatment failure and disease persistence. This narrative review discusses biofilm production by respiratory pathogens such as Streptococcus pneumoniae, non-typeable Haemophilus influenzae, Pseudomonas aeruginosa, and Staphylococcus aureus. It examines their mechanisms of biofilm formation, antibiotic resistance, and the challenges they present in clinical treatment. Various antibiofilm strategies have shown promise in vitro and in animal studies, including the use of N-acetylcysteine, enzymes like dispersin B, and agents disrupting quorum sensing and biofilm matrix components. However, their clinical application, particularly in children, remains limited. Traditional treatments for biofilm-associated diseases have not significantly evolved, even with biofilm detection. The transition from experimental findings to clinical practice is complex and requires robust clinical trials and standardized biofilm detection protocols. Addressing biofilms in pediatric respiratory infections is crucial for improving treatment outcomes and managing recurrent and chronic diseases effectively.

The efficacy of the adaptive immune system in the middle ear (ME) is well established, but the mechanisms are not as well defined as those of gastrointestinal or respiratory tracts. While cellular elements of the adaptive response have been detected in the MEs following infections (or intranasal immunizations), their specific contributions to protecting the organ against reinfections are unknown. How immune protection mechanisms of the MEs compares with those in the adjacent and attached upper and lower respiratory airways remains unclear. To address these knowledge gaps, we used an established mouse respiratory infection model that we recently showed also involves ME infections. Bordetella bronchiseptica delivered to the external nares of mice in tiny numbers very efficiently infects the respiratory tract and ascends the Eustachian tube to colonize and infect the MEs, where it causes severe but acute inflammation resembling human acute otitis media (AOM). Since this AOM naturally resolves, we here examine the immunological mechanisms that clear infection and protect against subsequent infection, to guide efforts to induce protective immunity in the ME. Our results show that once the MEs are cleared of a primary B. bronchiseptica infection, the convalescent organ is strongly protected from reinfection by the pathogen despite its persistence in the upper respiratory tract, suggesting important immunological differences in these adjacent and connected organs. CD4+ and CD8+ T cells trafficked to the MEs following infection and were necessary to robustly protect against secondary challenge. Intranasal vaccination with heat killed B. bronchiseptica conferred robust protection against infection to the MEs, even though the nasopharynx itself was only partially protected. These data establish the MEs as discrete effector sites of adaptive immunity and shows that effective protection in the MEs and the respiratory tract is significantly different. This model system allows the dissection of immunological mechanisms that can prevent bacteria in the nasopharynx from ascending the ET to colonize the ME. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to analyze the relationship between breastfeeding duration and adenoid size, snoring and acute otitis media (AOM). Methods: We analyzed the medical history of children admitted to the ENT outpatient clinic in 2022 and 2023, reported symptoms, ear, nose and throat (ENT) examination, and flexible nasopharyngoscopy examination of 145 children aged 3–5 years. Results: Breastfeeding duration of 3 and 6 months or more had a significant effect on the reduction of snoring (p = 0.021; p = 0.039). However, it had no effect on the adenoid size, mucus coverage and sleeping with an open mouth. Snoring was correlated with open mouth sleeping (p < 0.001), adenoid size with a 75% A/C ratio or more (p < 0.001), and adenoid mucus coverage in the Mucus of Adenoid Scale by Nasopharyngoscopy Assessment—MASNA scale (p = 0.009). Children who were breastfed for less than 3 months had more than a four-fold greater risk of snoring. There was a statistically significant correlation between AOM and gender (p = 0.033), breastfeeding duration in groups fed 1, 3 or 6 months or more (p = 0.018; p = 0.004; p = 0.004) and those fed with mother's breast milk 3 or 6 months or more (p = 0.009; p = 0.010). Moreover, a correlation was found between adenoid size and mucus coverage, tympanogram, and open-mouth sleeping (p < 0.001). Independent factors of snoring in 3- to 5-year-old children were breastfeeding duration of less than 3 months (p = 0.032), adenoid size with an A/C ratio of 75% or more (p = 0.023) and open mouth sleeping (p = 0.001). Conclusions: Children breastfed for 3 and 6 months or more exhibited reduced rates of snoring. There was no effect of breastfeeding duration on adenoid size in children aged 3 to 5 years, suggesting that the link between breastfeeding duration and snoring is primarily associated with craniofacial development and muscle tone stimulation. A breastfeeding duration of 1 month or more plays a key role in reducing the rate of AOM. The mother's milk plays a protective role against AOM. The presence of mucus might be responsible for snoring in preschool children. A medical history of breastfeeding should be taken into consideration when snoring children are suspected of adenoid hypertrophy. [ABSTRACT FROM AUTHOR]

Inner ear involvement (IED) is a rare local complication of the very common acute otitis media (AOM). The most beneficial treatment for IED remains a matter of debate. The aim of this study is to analyze different treatment modalities based on hearing outcomes to contribute to the discussion of therapy for IED in AOM. This retrospective study includes 112 adult patients diagnosed with AOM with IED between 2000 and 2020. Patients either received conservative (systemic antibiotic and systemic steroid therapy), interventional (conservative plus myringotomy and tympanic tube) or operative (interventional plus antrotomy) treatment. Pre- and post-treatment pure tone audiometry was performed. The hearing outcome was compared, and hearing recovery was analyzed based on modified Siegel's criteria. The pre-treatment pure tone average (PTA) was significantly (p < 0.05) higher in the operative group than in the other groups. All treatment modalities led to a significant hearing improvement (p < 0.001). The pre- and post-treatment hearing loss was predominantly observed in high frequencies 2–4 kHz. The operative group showed the highest rate of complete hearing recovery. While all treatment modalities led to a significant improvement in hearing, the operative group showed the most beneficial hearing results in patients with high pre-treatment hearing loss. It remains to be shown if the findings in patients with high pre-treatment hearing loss can be generalized to patients with mild or moderate pre-treatment hearing loss. [ABSTRACT FROM AUTHOR]

Introduction: Chronic otitis media (COM) is an inflammatory process in the middle ear cleft that results in permanent changes in the tympanic membrane including atelectasis, dimer formation, tympanosclerosis, retraction pocket development, or cholesteatoma. There is variable involvement of ossicular chain. Chronic otitis media results from long-term eustachian tube dysfunction with a poorly aerated middle-ear space, multiple bouts of acute otitis media, chronic otitis media with effusion and persistent middle ear infections. Materials and Methods: All patients under 18 years age diagnosed with cholesteatoma in outpatient department and inpatient at B.Y.L NAIR CHARITABLE HOSPITAL (from January 2018 to October 2018) who satisfied the inclusion and exclusion criteria were included in the study. Informed consent was taken from each patient or their guardian and study was explained to each one of them. Detailed clinical examination involving examination through otoscopic findings was performed. Patients were subjected to tuning fork tests like Rinne’s and Weber’s test along with pure tone audiometry as per standard care and protocol. Patients also underwent radiological evaluation like HRCT temporal bone. Results: 53.33 % patients belonged in the age group of 13-18 years followed by children between 5-12 years were 40%. Female patients comprised 20 (66.67%) of the study. The ratio of male to female was 1:2. In 40 % patient’s right side was involved, left side and both the ears were involved in 30%.Thus unilateral involvement was more common i.e. in 70% patients. The most common type of hearing loss seen was moderate conductive hearing loss, in 30% patients, followed by mild and moderately severe conductive hearing loss, in 26.67% patients. Conclusion: In our study most patients presented with a long duration of disease which was due to lack of awareness in our country regarding the disease. During the initial presentations the patients were often evaluated by general physicians and not otorhinolaryngologists in primary and secondary centres. These patients usually received only symptomatic treatment initially and were referred to higher centre when the disease did not respond to the same. Hence by the time patients present to us, the disease was already extensive. [ABSTRACT FROM AUTHOR]

Streptococcus pneumoniae having almost 98 serotypes and being common cause of acute otitis media, pneumonia, bacteremia, meningitis etc., which results in high mortality and morbidity globally. Although vaccines like PCV-13 and PPV-23 are available, some problems like serotype replacement and poor immunogenicity in children, old age and immunocompromised people has been observed. To overcome these drawbacks protein/peptide-based vaccine can be a good strategy as these provides wide serotype coverage. However, immunogenicity of protein subunit vaccines is lower, that issue can be solved by using adjuvants. Recently nanoparticles as an adjuvant for vaccine delivery being used, which has provided not only good immunogenicity but also improved delivery and efficiency of protein-based vaccines. In this review we have discussed the latest advancement of nanoparticles-based protein/peptide vaccine delivery for Streptococcus pneumoniae. [ABSTRACT FROM AUTHOR]

Acute otitis media (AOM) is one of the most common ENT diseases in children. In the antibiotic/post-antibiotic era, facial paralysis is a very rare complication of AOM (0.004–0.005%). Despite the rarity of this complication, it should be known by all physicians for proper therapeutic management to avoid serious sequelae. The aim of this review is to provide a management guide based on the current literature. Materials and Methods: Fifteen studies published between 2000 and 2022 were selected, including 120 patients (62 M/58 F) with an average age of 4.96 years old (range = 4 months–16 years; SD: 4.2). The paralysis frequently has a sudden onset and is of a severe grade (medium House–Brackmann (HB) score at onset: 4.68; SD: 0.5); however, it tends to have an almost complete recovery in most patients (88.49% HB 1 at follow-up). Results: Its first-line treatment must be based on the use of antibiotics (beta-lactam antibiotics as penicillins or cephalosporins). Corticosteroids should be used concomitantly for their anti-inflammatory and neuroprotective actions; however, there is no unanimity between authors about their application. Myringotomy, with or without ventilation tube insertion, is indicated in cases where the tympanic membrane is intact. Other kinds of surgery should be performed only in patients who have a worsening of their AOM symptoms or a worsening in HB score even with clinical treatment. Conclusions: The obtained data show that a conservative treatment can be sufficient for complete recovery in most patients, and it is preferred as the first-line therapy. Mastoidectomy should be performed only in patients with acute mastoiditis and without symptom improvement after a conservative approach. There are insufficient data in the current literature to provide clear selection criteria for patients who need to undergo mastoidectomy with facial nerve decompression. The choice of this treatment is based on an individual center expertise. Further studies are needed to clarify the role of corticosteroids and the role of facial nerve decompression in this clinical scenario. [ABSTRACT FROM AUTHOR]

To compare the effectiveness of amoxicillin administered in regimens of two or three daily doses in children with acute otitis media (AOM). As a secondary aim, we measured and compared treatment adherence between the two groups. A prospective observational study was conducted in the emergency department of a children's hospital. We recruited a total of 353 patients having a median age of 1.58 years. Twice-daily dosing was prescribed to 58%, while 42% received three doses per day. The clinical course of AOM was favourable in 92% of the patients who received two doses of amoxicillin and in 95% of those who received three doses (p = 0.25). Four patients (1%) had persistent symptoms beyond day 7. None developed intracranial complications. In the group receiving three doses daily, 31% reported difficulties with the dosing schedule, and 9.6% faced challenges when administering the medication at the specified volume, compared with 5.8% and 25% of those who received the two-dose regimen, respectively. Conclusion: Twice-daily amoxicillin has similar efficacy to a three-dose daily regimen and can offer advantages for caregivers in terms of administration schedule. What is Known: • Amoxicillin given in two daily doses is as effective as a three doses regimen in the treatment of acute otitis media in children. • The lower the number of daily doses, the higher the adherence to a drug treatment. What is New: • Administration of amoxicillin in twice-daily doses may improve adherence, as it is less frequently associated with family-perceived problems with dosing schedules.

Objective: To provide an analysis of complications following eustachian tube balloon dilation as well as their treatments and outcomes. Data Sources: PubMed, Ovid Embase, and MAUDE Database. Review Methods: A systematic approach following PRISMA guidelines was used to identify publications pertaining to balloon dilation of the eustachian tube from PubMed and Ovid Embase databases was used. Once these publications were critically reviewed, the primary outcome extracted were reported complications. Additional complications were collected in the Manufacturer and User Facility Device Experience (MAUDE) database using the product class "eustachian tube dilation device" and searching through relevant manufacturers. Complications and outcomes were compared between these sources. Results: Fifty five full‐length manuscripts involving 7155 patients were included and 98 complications reported for a 1.4% complication rate. The most frequently reported adverse events were subcutaneous emphysema of the head and neck (19%), epistaxis (12%), and acute otitis media (11%). The MAUDE search returned 18 distinct patient entries, of which 12 (67%) reported complications. The most reported complications in the MAUDE database included subcutaneous emphysema (8, 67%) and pneumomediastinum (3, 25%). The most serious complication was a carotid artery dissection reported in one patient in the MAUDE database. Conclusion: Eustachian tube dilation is rarely associated with complications, which nevertheless may lead to morbidity and medical emergencies. Patients and providers should recognize potential risks associated with this intervention as well as methods to manage complications. [ABSTRACT FROM AUTHOR]

Background – Chronic suppurative otitis media is a permanent abnormality of the middle ear which is most likely as a result of earlier acute otitis media, negative middle ear pressure, otitis media with effusion. It requires evaluation of both the ear as disease in one side,affect another ear also. Aim & objective – To know the status of contralateral ear in patients with unilateral chronic otitis media and role of otoendoscopy in its assessment. Method – A prospective observational study was done on 100 patients of both the sex, with chronic otitis media in one ear. Contralateral ear of all patients was analysed clinically using otoscope, audiologically, endoscopically using otoendoscope. Result – Out of 100 patients 27% were male and 73% were female. Otoendoscopy of contralateral ear reveals out of 100 patients, 36% had normal finding, 51% had normal hearing while 32% showed mild conductive hearing loss in CLE. Conclusion –Evaluation of contralateral ear in unilateral chronic otitis media is crucial as it affect other ear in terms of hearing loss, tympanic membrane retraction and even chronic otitis media up to some extent.

Acute otitis media (AOM) is one of the most common diseases found in the pediatric population. This disease is characterized by protrusion or bulging of the tympanic membrane which occurs together with otalgia and non-specific symptoms such as fever, irritability and malaise. Risk factors for this disease are related to young age, genetics, a history of recurrent upper respiratory tract infections, immune system disorders and facial anatomical abnormalities that affect the function of the eustachian tube. AOM needs appropriate treatment to prevent future complications such as speech and language disorders in children due to decreased hearing function caused by this disease. This literature review aims to discuss the current diagnosis and management of acute otitis media. [ABSTRACT FROM AUTHOR]

Introduction: The infection due to Streptococcus pneumoniae constitutes an important cause of morbimortality in the world, mainly in children under 5 years, that causes from 1 to 2 million annual deaths. Objective: To determine the presence of S. pneumoniae in clinical samples obtained in children. Methods: A descriptive and cross-sectional study was carried out in children under 5 years with clinical diagnosis of invasive pneumococcus disease, assisted in two children hospitals from Santiago de Cuba during the period 2014-2018. Of the 1466 clinical samples taken and processed, in 131 the pathogen agent was isolated; these corresponded to 59 patients with clinical forms of the infection and 72 carriers of the disease. For the statistical processing of the information the absolute and relative frequencies were used as summary measures. Results: In general the positivity for S. pneumoniae was of 8.9 %, with more isolation frequencies in the samples of cerebrospinal fluid (81.8 %), pleural fluid (47.1 %) and otic exudate (21.9 %) that also coincided with the highest percentages of pneumonia (61.0), acute otitis media (23.7) and meningitis (15.3), as clinical forms of the neumococcus disease that mainly affected 1 year children, followed by those over 2 years. In a same way, 9 serotypes of S. pneumoniae were identified, with prevalence of the 19A (39.0 %), and 14 (25.4 %) and the 6A (11.9 %). In the nasopharyngeal carriers 8 serotypes were identified, of which the 19A and 14 prevailed. Lastly, a high microbian resistance to erythromycin and the combination trimethoprim-sulfametoxazole was found. Conclusions: The results of this study provided a scientific referent before the introduction of the Cuban antipneumococcus vaccine that will allow to evaluate its impact in the incidence of this disease.

Haemophilus influenzae (Hi) is one of the leading bacteria implicated in childhood acute otitis media (AOM). Recent concerns have been raised about the emergence of Hi-resistant strains. We aimed to analyze the evolution of β-lactam resistance to Hi among strains isolated from nasopharyngeal carriage in children with AOM and in mild ear fluid (MEF) after the spontaneous perforation of the tympanic membrane (SPTM) in France. In this national ambulatory-based cohort study over 16 years, we analyzed the rate of Hi nasopharyngeal carriage and the proportion of β-lactam-resistant Hi strains over time using a segmented linear regression model. Among the 13,865 children (median [IQR] age, 12.7 [9.3–17.3] months; 7400 [53.4%] male) with AOM included from November 2006 to July 2022, Hi was isolated in 7311 (52.7%) children by nasopharyngeal sampling. The proportion of β-lactamase-producing and β-lactamase-negative, ampicillin-resistant (BLNAR) Hi strains in nasopharyngeal carriage remained stable during the study period. Among the 783 children (median [IQR] age, 20 [12.3–37.8] months; 409 [52.2%] male) with SPTM included from October 2015 to July 2022, Hi was isolated in 177 (22.6%) cases by MEF sampling. The proportions of β-lactamase-producing and BLNAR Hi strains did not significantly differ between nasopharyngeal (17.6% and 8.8%, respectively) and MEF (12.6% and 7.4%) samples. Accordingly, amoxicillin remains a valid recommendation as the first-line drug for AOM in France. [ABSTRACT FROM AUTHOR]

Introduction: Studies on risk factors for childhood hearing loss (HL) are usually based on questionnaires or small sample sizes. We conducted a nationwide population-based case-control study to comprehensively analyze the maternal, perinatal, and postnatal risk factors for HL in full-term children. Methods: We retrieved data from three nationwide databases related to maternal characteristics, perinatal comorbidities, and postnatal characteristics and adverse events. We used 1:5 propensity score matching to include 12,873 full-term children with HL and 64,365 age-, sex-, and enrolled year-matched controls. Conditional logistic regression was used to evaluate the risk factors for HL. Results: Among the various maternal factors, maternal HL (adjusted odds ratio [aOR]: 8.09, 95% confidence interval [95% CI]: 7.16–9.16) and type 1 diabetes (aOR: 3.79, 95% CI: 1.98–7.24) had the highest odds of childhood hearing impairment. The major perinatal risk factors for childhood hearing impairment included ear malformations (aOR: 58.78, 95% CI: 37.5–92.0) and chromosomal anomalies (aOR: 6.70, 95% CI: 5.25–8.55), and the major postnatal risk factors included meningitis (aOR: 2.08, 95% CI: 1.18–3.67) and seizure (aOR: 3.71, 95% CI: 2.88–4.77). Other factors included acute otitis media, postnatal ototoxic drug use, and congenital infections. Conclusions: Many risk factors for childhood HL identified in our study are preventable, such as congenital infection, meningitis, ototoxic drug use, and some maternal comorbidities. Accordingly, more effort is required to prevent and control the severity of maternal comorbidities during pregnancy, initiate genetic diagnostic evaluation for high-risk children, and aggressive screening for neonatal infections.

Abstract Acute otitis media (AOM) is the most common childhood bacterial infectious disease requiring antimicrobial therapy. Most cases of AOM are caused by translocation of Streptococcus pneumoniae or Haemophilus influenzae from the nasopharynx to the middle ear during an upper respiratory tract infection (URI). Ongoing genomic surveillance of these pathogens is important for vaccine design and tracking of emerging variants, as well as for monitoring patterns of antibiotic resistance to inform treatment strategies and stewardship. In this work, we examined the ability of a genomics-based workflow to determine microbiological and clinically relevant information from cultured bacterial isolates obtained from patients with AOM or an URI. We performed whole genome sequencing (WGS) and analysis of 148 bacterial isolates cultured from the nasopharynx (N = 124, 94 AOM and 30 URI) and ear (N = 24, all AOM) of 101 children aged 6–35 months presenting with AOM or an URI. We then performed WGS-based sequence typing and antimicrobial resistance profiling of each strain and compared results to those obtained from traditional microbiological phenotyping. WGS of clinical isolates resulted in 71 S. pneumoniae genomes and 76 H. influenzae genomes. Multilocus sequencing typing (MSLT) identified 33 sequence types for S. pneumoniae and 19 predicted serotypes including the most frequent serotypes 35B and 3. Genome analysis predicted 30% of S. pneumoniae isolates to have complete or intermediate penicillin resistance. AMR predictions for S. pneumoniae isolates had strong agreement with clinical susceptibility testing results for beta-lactam and non beta-lactam antibiotics, with a mean sensitivity of 93% (86–100%) and a mean specificity of 98% (94–100%). MLST identified 29 H. influenzae sequence types. Genome analysis identified beta-lactamase genes in 30% of H. influenzae strains, which was 100% in agreement with clinical beta-lactamase testing. We also identified a divergent highly antibiotic-resistant strain of S. pneumoniae, and found its closest sequenced strains, also isolated from nasopharyngeal samples from over 15 years ago. Ultimately, our work provides the groundwork for clinical WGS-based workflows to aid in detection and analysis of H. influenzae and S. pneumoniae isolates.

Background: Otitis media is infection of the middle ear cleft, which comprises acute and chronic otitis media and otitis media with effusion. Acute otitis media (AOM) is the second most prevalent pediatric emergency. Aims and Objectives: The aim of the study was to assess the epidemiology and clinical manifestations of AOM cases reported to the ENT OPD. Materials and Methods: A retrospective study was conducted in a tertiary care center of Assam from January 2021 to December 2022. A total of 840 patients from a wide range of socioeconomic strata were included in the study who belong to Upper Assam, parts of Arunachal Pradesh and Nagaland region. Results: Majority (25.8%) of the patients were below the age of 10 years. The age group of 31–40 years (25.2%) was next in line. In the age range of 71–80 years, the least number of patients (0.3%) were observed. The majority (53.09%) of the patients were from Dibrugarh district of Assam. Conclusion: This study has brought to light the prevalence of AOM in this region and the need for the health department to raise public understanding of the significance of a healthy lifestyle in the prevention of AOM, early diagnosis, and treatment.

In recent years, the use of smartphones and other wireless technology in medical care has developed rapidly. However, in some cases, especially for pediatric medical problems, the reliability of information accessed by mobile health technology remains debatable. The main aim of this paper is to evaluate the relevance of smartphone applications in the detection and diagnosis of pediatric medical conditions for which the greatest number of applications have been developed. This is the case of smartphone applications developed for the diagnosis of acute otitis media, otitis media with effusion, hearing impairment, obesity, amblyopia, and vision screening. In some cases, the information given by these applications has significantly improved the diagnostic ability of physicians. However, distinguishing between applications that can be effective and those that may lead to mistakes can be very difficult. This highlights the importance of a careful application selection before including smartphone-based artificial intelligence in everyday clinical practice.

Abstract Cerebral venous thrombosis (CVT) is a rare entity that remains a diagnostic challenge due to various clinical manifestations and a wide variety of causative agents. Local infections, such as acute (AOM) or chronic otitis media, can play a role in the pathogenesis of CVT. The proximity of the tympanic cavity and temporal bone air cells to the dural venous sinuses predisposes them to secondary thrombosis. The release of inflammatory cytokines and activation of the coagulation pathway in the middle ear space in response to infection may trigger the thrombotic mechanism in venous sinuses of the central nervous system. There is no consensus in the literature concerning the treatment of otogenic cerebral venous sinus thrombosis (CVST). Both the extent of the surgery and the use of anticoagulants are disputable. The aim of the study was to provide a thorough analysis of the literature concerning CVST in patients with AOM and acute mastoiditis (AM). The current surgical and conventional treatment strategies are presented. Special attention has been attached to the predisposing factors, the extent of the surgery, and the role of anticoagulants in the treatment of septic otogenic CVST.

Various types of otitis are common in the pediatric population. The use of otoscopy techniques by primary care doctors (pediatricians, family, and general practitioners) has significantly expanded the diagnostic capabilities of the primary examination of the child. However, it requires many specialists to know the principles of patient management with various types of otitis media. The article addresses the principles of routing and drug therapy for patients with various types of otitis media. The focus is on ear drops (formulation, indications for using specific drugs, safety, and age-related aspects).

Abstract Background Streptococcus pneumoniae remains a leading cause of morbidity, mortality, and healthcare resource utilization (HRU) among children. This study quantified HRU and cost of acute otitis media (AOM), pneumonia, and invasive pneumococcal disease (IPD). Methods The IBM MarketScan® Commercial Claims and Encounters and Multi-State Medicaid databases from 2014 to 2018 were analyzed. Children with AOM, all-cause pneumonia, or IPD episodes were identified using diagnosis codes in inpatient and outpatient claims. HRU and costs were described for each condition in the commercial and Medicaid-insured populations. National estimates of the number of episodes and total cost ($US 2019 for each condition were extrapolated using data from the US Census Bureau. Results Approximately 6.2 and 5.6 million AOM episodes were identified in commercial and Medicaid-insured children, respectively, during the study period. Mean cost per AOM episode was $329 (SD $1505) for commercial and $184 (SD $1524) for Medicaid-insured children. A total of 619,876 and 531,095 all-cause pneumonia cases were identified among commercial and Medicaid-insured children, respectively. Mean cost per all-cause pneumonia episode was $2304 (SD $32,309) in the commercial and $1682 (SD $19,282) in the Medicaid-insured population. A total of 858 and 1130 IPD episodes were identified among commercial and Medicaid-insured children, respectively. Mean cost per IPD episode was $53,213 (SD $159,904) for commercial and $23,482 (SD $86,209) for the Medicaid-insured population. Nationally, there were over 15.8 million cases of AOM annually, with total estimated cost of $4.3 billion, over 1.5 million cases of pneumonia annually, with total cost of $3.6 billion, and about 2200 IPD episodes annually, for a cost of $98 million. Conclusions The economic burden of AOM, pneumonia, and IPD among US children remains substantial. IPD and its manifestations were associated with higher HRU and costs per episode, compared to AOM and all-cause pneumonia. However, owing to their higher frequencies, AOM and all-cause pneumonia were the main contributors to the economic burden of pneumococcal disease nationally. Additional interventions, such as the development of pneumococcal conjugate vaccinees with sustained protection of existing vaccine type serotypes as well as broader inclusion of additional serotypes, are necessary to further reduce the burden of disease caused by these manifestations.
