Int J Pediatr Otorhinolaryngol 2024; 178:111861. [PMID: 38340606 DOI: 10.1016/j.ijporl.2024.111861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 12/19/2023] [Accepted: 01/09/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVE To summarise the published research evidence on the epidemiology of otitis media, including the risk factors and sequelae associated with this condition. DATA SOURCES Medline (PubMed), Embase, and the Cochrane Library covering the period from 2019 to June 1st, 2023. REVIEW METHODS We conducted a broad search strategy using otitis [Medical Subject Heading] combined with text words to identify relevant articles on the prevalence, incidence, risk factors, complications, and sequelae for acute otitis media, otitis media with effusion, and chronic suppurative otitis media. At least one review author independently screened titles and abstracts of the retrieved records for each condition to determine whether the research study was eligible for inclusion. Any discrepancies were resolved by reviewing the full text followed by discussion with a second review author. Studies with more than 100 participants were prioritised. RESULTS Over 2,000 papers on otitis media (OM) have been published since 2019. Our review has highlighted around 100 of these publications. While the amount of otitis media research on the Medline database published each year has not increased, there has been an increase in epidemiological studies using routinely collected data and systematic review methodology. Most of the large incidence studies have addressed acute otitis media (AOM) in children. Several studies have described a decrease in incidence of AOM after the introduction of conjugate PCV vaccines. Similarly, a decrease was noted when rates of coronavirus disease of 2019 (COVID-19) were high and there were major public health efforts to reduce the spread of infection. There have been new studies on OM in adults and OM prevalence in a broader range of countries and population subgroups. CONCLUSION Overall, the rates of severe and/or suppurative OM appeared to be decreasing. However, there is substantial heterogeneity between populations. While better use of available data is informative, it can be difficult to predict rates of severe disease without accurate examination findings. Most memorably, the COVID-19 pandemic had an enormous impact on the research and clinical services for otitis media for most of the period under review. IMPLICATIONS FOR PRACTICE The use of routinely collected data for epidemiological studies will lead to greater variability in the definitions and diagnostic criteria used. The impact of new vaccines will continue to be important. Some of the lessons learned during the COVID-19 pandemic concerning behaviours that reduce spread of respiratory viruses can hopefully be used to decrease the burden of otitis media in the future. There are still many countries in the world where the burden of otitis media is not well described. In countries where otitis media has been studied over many years, new potential risk factors continue to be identified. In addition, a better understanding of the disease in specific subgroups has been achieved.

Identifying distinct trajectories of acute otitis media in children: A prospective cohort study. Clin Otolaryngol 2021; 46:788-795. [PMID: 33555145 PMCID: PMC8248120 DOI: 10.1111/coa.13736] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 01/07/2021] [Accepted: 01/24/2021] [Indexed: 01/09/2023]
Abstract
Objectives To identify possibly distinct acute otitis media (AOM) trajectories in childhood and identify determinants associated with specific AOM trajectories. To explore which child will become prone to recurrent AOM episodes and which will not. Design Population‐based prospective cohort study among 7863 children from birth until 10 years and their mothers. Methods This study was embedded in the Generation R Study: a population‐based prospective cohort study. Data on AOM and determinants were collected by repeated parental questionnaires. Distinct AOM trajectories within the population were identified with latent‐class analyses. Next, using multivariate analysis we checked whether specific determinants were associated with specific trajectories. Results Three distinct trajectories were identified; that is, non–otitis prone, early AOM—that is children who suffered AOM episodes until 3 years of age but not beyond, and persistent AOM—that is children who remained otitis‐prone. Male gender (OR: 1.26, CI: 1.11‐1.43) and day‐care attendance (OR: 1.31, CI: 1.06‐1.60) were associated with increased odds of early AOM. Breastfeeding was beneficial for children in both the early‐AOM and persistent‐AOM trajectories (OR: 0.78 and 0.77, respectively). Birth in the summer or autumn as compared with birth in the spring decreased odds of AOM only in the persistent‐AOM trajectory. Half of all AOM‐prone children recovered after the age of 3 years. Conclusion Specific determinants are associated with different AOM trajectories. Future research is needed to better predict which child will remain otitis‐prone and which recovers after the age of 3 years to better tailor treatment towards the needs of the individual child.

Abstract
BACKGROUND Acute otitis media (AOM) is a common pediatric disease and frequent reason for antibiotic treatment. We aimed to identify environmental and host factors associated with AOM and assess which determinants were associated with AOM at specific ages. METHODS This study among 7863 children was embedded in the Generation R Study: a population-based prospective cohort study from fetal life onwards. Data on outcome and possible determinants were collected using questionnaires until 6 years. We used generalized estimating equation models to examine associations with AOM with longitudinal odds at different ages, considering correlations between repeated measurements. RESULTS Male gender increased odds of AOM in children at 2, 3, and 4 years but not at other ages. Postnatal household smoking, presence of siblings, and pet birds increased odds of AOM. Breastfeeding decreased AOM odds, most notably in the first 2 months of life. No association was found for season of birth, maternal age, ethnicity, aberrant birth weight for gestational age, prenatal smoking, furry pets, and daycare attendance. CONCLUSIONS Risk of childhood AOM varies with age. Significant association with AOM was found for gender and breastfeeding at specific ages and for household smoking, presence of siblings, and pet birds at all the studied ages.

Birth Season and Infection Risk Among Children Under 5 Years Old: A Study of Hospital Admissions and Short Message Service-reported Symptoms at Home. Pediatr Infect Dis J 2020; 39:23-29.

Abstract
BACKGROUND The season in which a child is born may affect the immune system development and thereby influence the risk of infections. In this study, we examined the associations between birth season and the risk of hospital admission or symptoms associated with a wide range of infections. METHODS This study is a prospective cohort study of 2434 children with an average follow-up of 3.5 years. Admission data were obtained from the Danish National Patient Registry. Via short message service (SMS) questionnaires, 1279 families reported symptoms of infections in a 1-year period. RESULTS Of the 2434 children, 639 (26.3%) were admitted to the hospital, and the children experienced on average 64.4 days with symptoms of infection within 1 year. There was no association between birth season and hospital admissions due to all infectious causes [incidence rate ratio (IRR) = 0.89; 95% confidence interval (CI), 0.65-1.22; P = 0.471]. However, children born in the fall had a higher IRR for admission due to all infectious causes when excluding admissions within the first year of life. Winter- and spring-born children had lower IRRs for admission due to gastrointestinal infections than summer-born children, but this association was alone present when admissions within the first year of life were included. The short message service-survey showed significantly lower IRRs for any symptom of infection among winter-born (IRR = 0.85; 95% CI, 0.75-0.96; P = 0.009) and fall-born children (IRR = 0.88; 95% CI, 0.78-0.99; P = 0.033) in comparison with summer-born children. CONCLUSIONS Birth season was not associated with hospital admission due to all infectious causes within the first 5 years of age; however, fall-birth was associated with a higher IRR for admissions due to all infectious causes after the first year of life. The association between birth season and admissions due to gastrointestinal infections was only seen when including children admitted under the age of one. Being born in fall or winter was associated with a decreased IRR for number of days with any symptom of infection registered at home.

Abstract
BACKGROUND Age at exposure to acute otitis media (AOM) risk factors such as day care attendance, lack of breastfeeding and tobacco smoke is little studied but important for targeting AOM prevention strategies. Moreover, studies are typically restricted to clinically diagnosed AOM, while a significant subset can occur outside the health care system, depending on the country setting. This study aims to determine risk factor exposure and effect of its timing within the first year of life on parent-reported AOM symptom episodes. METHODS In the WHeezing and Illnesses STudy LEidsche Rijn birth-cohort study, 1056 children were prospectively followed during their first year of life. Group day care attendance, breastfeeding and tobacco smoke exposure were recorded monthly and parent-reported AOM symptoms daily. Generalized estimating equations were used to estimate the association between the time-varying risk factors and AOM symptom episodes, while correcting for confounding by indication. RESULTS The first-year incidence rate of parent-reported AOM was 569/1000 child-years [95% confidence interval (CI): 523-618]. Children who attended day care had higher odds of developing AOM symptom episodes compared with those not attending (odds ratio: 5.0; 95% CI: 2.6-9.6). Tobacco smoke exposure and (a history of) breastfeeding were not associated with AOM. Test for interaction revealed that the effect of day care increased with each month younger in age. CONCLUSIONS First-year day care attendance is a major risk factor for AOM symptom episodes among infants in the community. This adjusted effect estimate is higher than previously reported and is age-dependent. AOM prevention strategies in day care facilities should therefore focus in particular on the youngest age groups.

Abstract
OBJECTIVES Season of birth (SOB) is a medical term used to describe the relationship between the season in which one is born and his or her physiologic and pathological characteristics. In East Asian medicine, the Un-Gi SOB is based on the Yin-yang-Five Phases theory. The purpose of this study is to examine the relationship between Un-Gi SOB and a multitude of clinical symptoms and signs, and to examine which of the Un and Gi seasons has the greatest impact on these symptoms and signs. METHODS Using the Delphi method, three Un-Gi experts formulated a 26-item questionnaire consisting of clinical symptoms and signs, with each item rated on a Likert 7-point scale. A total of 1057 Korean adolescents (583 males, 474 females) completed the 26-item questionnaire. After identifying the Un and Gi seasons of all subjects, item scores were evaluated to determine whether there was a difference between Un and Gi seasons. RESULTS For Un seasons, males born in the Wood season had greater indigestion and were less physically active, whereas females born in the Earth season were better able to concentrate but had slower rates of growth. For Gi seasons, males born in the Fire season had greater indigestion and morning fatigue, and males born in the Earth season had higher tension. There was no relationship between symptoms, signs, and the Gi SOB in females. This indicates that males born in Wood Un and Gi seasons are susceptible to Earth-related clinical problems, whereas females born in the Earth Un season are susceptible to Earth-related clinical problems. CONCLUSIONS The study results suggest that Un-Gi seasons based on the Yin-yang-Five Phases are related to clinical symptoms and signs, with significant differences between genders.

Abstract
The 2007 Recent Advances in Otitis Media Research Conference Panel Report provides an update on otitis media (OM) research published from 2003 to 2007. This report summarizes important trends in disease incidence and prevalence, describes established and newly identified risk factors for acute and chronic OM and OM with effusion, and conveys information on newly discovered genetic factors. In this report, researchers have described declining rates of OM diagnosis, antibiotic prescriptions, offices visits for OM, and middle ear surgery since the licensure and routine use of pneumococcal conjugate vaccine in infants. The panel report also recommends short and long term goals for current and future OM research.

Abstract
Otitis media (OM) is the accumulation of fluids in the middle ear, with or without symptoms of inflammation. The infection is caused by dysfunction or obstruction of the eustachian tube and is most commonly diagnosed in children under the age of two. The microbiology of OM differs, with Streptococcus pneumoniae, non-typeable Haemophilus influenzae and Moraxella catarrhalis the most commonly isolated pathogens. The emergence of penicillin-resistant Strep. pneumoniae, β-lactamase-producing strains, Haem. influenzae and Mor. catarrhalis is a major concern and health care costs associated with treatment are substantial, especially in cases of unresponsive treatment as a result of incorrect diagnosis. Alternative treatments such as vaccines and a nasal spray containing α-haemolytic streptococci with antimicrobial activity against OM pathogens, have been developed. The rationale behind such treatments is to induce an appropriate immune response against the pathogens and decrease bacterial colonisation in the nasopharynx. Another approach may be treatment with bacteriocins (natural antimicrobial peptides) or bacteriocin-like inhibitory substances (BLIS) produced by lactic acid bacteria. We have recently described an antibacterial peptide produced by Enterococcus mundtii ST4SA and have published on bacteriocins (enterocins) with antibacterial and antiviral activity. This review discusses the condition OM, summarises current methods used to treat the infection, and suggests alternative safe and natural treatments that need to be explored.
