Prevalence Of Otitis Media Research Articles

Risk Factors for Otitis Media with Effusion in Preschool and School Children in Calabar Municipality.

Predisposing factors for otitis media with effusion are multifactorial, ranging from genetic and anatomical abnormalities to environmental factors and inflammation of the nose and adjacent structures. The study determined the risk factors for otitis media with effusion (OME) among children in Calabar Municipality. This was a descriptive, cross-sectional, community-based study including children aged 1-10 years randomly selected from government and privately owned daycares, nurseries (preschool), and primary schools. The risk factors assessed included upper respiratory tract infection, allergic rhinitis, adenoid enlargement, acute otitis media, recurrent acute otitis media parental educational level, overcrowding (four children sleeping in a room), duration of breastfeeding, cleft palate, and Down's syndrome. Allergic rhinitis was diagnosed when a child had at least two of the rhinological symptoms: nasal congestion, running nose, sneezing, itching of the eye or nose, and at least one of the following: history of allergy, family history of allergy, and positive history of asthma. The questionnaire was the research instrument used to assess the risk factors for OME. OME diagnosis was made with otoscopy and tympanometry. Data were collected and analyzed with IBM SPSS version 25, and a P value <0.05 was considered statistically significant. A total of 24 daycare pupils, 141 nursery pupils, and 155 primary pupils were recruited into the study. The prevalence of otitis media with effusion was more in younger children than in older children and the relationship was statistically significant (P < 0.001). Female children were more statistically affected than male children (P = 0.007). Children with allergic rhinitis accounted for a higher proportion of those with OME than those without allergic rhinitis (26.7% vs. 11.6%), and the difference was statistically significant (P = 0.007). The association between OME and upper respiratory tract infection, acute otitis media, and recurrent acute otitis media was not statistically significant (P > 0.05). Multivariate binary logistic regression was used to identify predictors for the otitis media with effusion. There are many endogenous and exogenous risk factors for OME, but notable risk factors in our study were age 1-2 years, female sex, and allergic rhinitis.

Changes in Otitis Media During COVID-19.

During the COVID-19 pandemic, various non-pharmaceutical interventions such as individual hygiene practices like hand washing, social distancing, and mandates for the use of masks in public spaces were implemented to reduce the spread of the disease. Otitis media (OM) is a common infectious disease. How the changed environment due to the COVID-19 pandemic has influenced the prevalence of infectious diseases like OM is not known. This study aimed to investigate how OM prevalence and trends changed during COVID-19 in Korea. OM patient data from 2017 to 2021 were extracted from the Health Insurance Review and Assessment Service database. Patients diagnosed with disease code H66 (suppurative and unspecified otitis media) were selected for analysis. Data on OM prevalence, gender, region, medical institution, and number of ventilating-tube prescriptions were analyzed. All age groups were included, and ages were categorized into 5-year ranges. The number of patients diagnosed with the OM disease code decreased continuously from 2017 to 2021 (1 598 205, 1 560 178, 1 520 948, 983 701, and 734 901). The average OM prevalence per 1000 persons decreased by 45.0% from 30.2 in 2017 to 2019 to 16.6 in 2020 to 2021. The change of OM prevalence was greater for the 0 to 5 age group than other age groups. The decrease in average prevalence per 1000 persons was greatest in the 0 to 5 age group (48.6% decrease from 358.2 in 2017-2019 to 184.1 in 2020-2021). The impact of environmental changes on ventilation-tube insertion was smaller than on OM prevalence. The average number of ventilating-tube insertions decreased by 28.1% from 27 311 in 2017 to 2019 to 19 650 in 2020 to 2021. OM prevalence decreased by 45.0%, and the number of ventilating-tube insertions decreased by 28.1% in Korea during COVID-19.

The Unneglectable Disease Burden of Otitis Media Among Children in China: A Systematic Review and Meta-analysis.

Otitis media (OM) is one of the most commonly diagnosed infections among children yet with obscure disease burden. The literature published from 1980 to 2022 was retrieved in PubMed, Ovid-EMBASE, Web of Science, CNKI, Wanfang and VIP. Literature screening, quality assessment and data extraction were conducted by 2 independent reviewers. Heterogeneity and publication bias were detected by I2 , Egger's and Begg's tests. The data were pooled using the random-effects model. The number of OM cases was estimated by the multiplied model based on pooled results and the 2020 China census data. A total of 28,378 literatures were identified with 67 finally included for data analysis. The OM incidence among children was 7.89% [95% confidence interval (CI): 5.43%-11.33%] and the prevalence of OM was 5.13% (95% CI: 3.49%-7.49%). The most common pathogen of the OM cases was Streptococcus pneumoniae ( S. pneumoniae ), with a positive rate of 33.52% (95% CI: 26.55%-41.29%). The most common serotypes of S. pneumoniae isolated from OM cases were serotypes 19F, 19A, 6B, 23F and 3, with 85.8% covered by the PCV13. We estimated that there were 8,950,797 (95% CI: 6,080,533-12,928,051) OM cases among under-fives in China in 2020, of which 3,374,451 (95% CI: 1,698,901-6,277,862) cases of OM were caused by S. pneumoniae . The burden of OM in China was considerable yet neglected. To date, S. pneumoniae was the most frequently detected bacterial pathogen of OM. Vaccination may be effective to protect young children from OM.

Otitis media at 6-monthly assessments of Australian First Nations children between ages 12–36 months: Findings from two randomised controlled trials of combined pneumococcal conjugate vaccines

ObjectivesIn remote communities of northern Australia, First Nations children with hearing loss are disproportionately at risk of poor school readiness and performance compared to their peers with no hearing loss. The aim of this trial is to prevent early childhood persisting otitis media (OM), associated hearing loss and developmental delay. To achieve this, we designed a mixed pneumococcal conjugate vaccine (PCV) schedule that could maximise immunogenicity and thereby prevent bacterial otitis media (OM) and a trajectory of educational and social disadvantage. MethodsIn two sequential parallel, open-label, randomised controlled trials, eligible infants were first allocated 1:1:1 to standard or mixed PCV primary schedules at age 28–38 days, then at age 12 months to a booster dose (1:1) of 13-valent PCV, PCV13 (Prevenar13®, +P), or 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugated vaccine, PHiD-CV10 (Synflorix®, +S). Here we report findings of standardised ear assessments conducted six-monthly from age 12–36 months, by booster dose. ResultsFrom March 2013 to September 2018, 261 children were allocated to booster + P (n = 131) or + S (n = 130). There were no significant differences in prevalence of any OM diagnosis by booster dose or when stratified by primary schedule. We found high, almost identical prevalence of OM in both boost groups at each age (for example 88% of 129 and 91% of 128 children seen, respectively, at primary endpoint age 18 months, difference −3% [95% Confidence Interval −11, 5]). At each age prevalence of bilateral OM was 52%–78%, and tympanic membrane perforation was 10%–18%. ConclusionDespite optimal pneumococcal immunisation, the high prevalence of OM persists throughout early childhood. Novel approaches to OM prevention are needed, along with improved early identification strategies and evaluation of expanded valency PCVs.

An evaluation of the quality of ear health services for Aboriginal children living in remote Australia: a cascade of care analysis

BackgroundIn the Northern Territory (NT) the prevalence of otitis media (OM) in young Aboriginal children living in remote communities has persisted at around 90% over the last few decades. OM-associated hearing loss can cause developmental delay and adversely impact life course trajectories. This study examined the 5-year trends in OM prevalence and quality of ear health services in remote NT communities.MethodsA retrospective analysis was performed on de-identified clinical data for 50 remote clinics managed by the NT Government. We report a 6-monthly cascade analysis of the proportions of children 0–16 years of age receiving local guideline recommendations for surveillance, OM treatment and follow-up at selected milestones between 2014 and 2018.ResultsBetween 6,326 and 6,557 individual children were included in the 6-monthly analyses. On average, 57% (95%CI: 56–59%) of eligible children had received one or more ear examination in each 6-monthly period. Of those examined, 36% (95%CI: 33–40%) were diagnosed with some type of OM, of whom 90% had OM requiring either immediate treatment or scheduled follow-up according to local guidelines. Outcomes of treatment and follow-up were recorded in 24% and 23% of cases, respectively. Significant decreasing temporal trends were found in the proportion diagnosed with any OM across each age group. Overall, this proportion decreased by 40% over the five years (from 43 to 26%).ConclusionsThis cascade of care analysis found that ear health surveillance and compliance with otitis media guidelines for treatment and follow-up were both low. Further research is required to identify effective strategies that improve ear health services in remote settings.

Factors Associated with Otitis Media Among Pediatrics in Two Government Hospitals in Arba Minch, Southern Ethiopia.

Bacterial otitis media (OM) is a common infection among the pediatric community worldwide and is the first reason for prescribing antibiotics in pediatric practices. However, if not promptly diagnosed and appropriately treated, it may persist and cause severe intra- and extra-cranial hard-to-cure complications. Hence, knowing the magnitude, etiology, and antibiotic susceptibility profile is very important for the proper management. A cross-sectional study was carried out in 312 pediatrics (1 to 18 years) attending the Ear Nose Throat outpatient departments of the two title hospitals from 25 February to 30th August 2022. Patients were chosen through a systematic random sampling method. Data were obtained by means of a semi-structured questionnaire. Samples were collected to identify the causative bacteria as per microbiological guidelines. The antibiotic susceptibility test was done according to the Kirby-Bauer disc diffusion; SPSS version 25 was used for the analysis. The overall prevalence of otitis media was 67.3% (n=210); CSOM showed a slight preponderance (n=107) Gram-negative bacteria and Gram-positive bacteria were present in 59.8% (n=137) and 40.1% (n=92), respectively. Otitis media was predominantly caused by S. aureus (n=52, 56.5%), followed by Proteus spp. (n=33, 24%). Gram-negative bacteria were highly resistant to co-trimoxazole, amoxicillin-clavulanic acid, piperacillin, and tetracycline, whereas their positive counterparts were considerably penicillin and co-trimoxazole resistant. Overall, 61.5 and 19.2% of the isolates were MDR and XDR, respectively. MRSA, MR-CoNs, and VRE were 38.4% (n=20), 17.1% (n=5), and 58.3% (n=12), respectively; 19.7% (n=25) ofGram-negative bacteria produced ESBL, and 7% (n=9) were carbapenem-resistant. History of exposure to loud noise [AOR=3.4; CI=1.14-10.23; P-value=0.028] and family history of smoking at home [AOR=2.9; CI=1.18-7.25; P-value=0.020] have the greatest odds of otitis media. Overall, the prevalence of otitis media is showing an upward trend, and MDR among bacterial isolates is increasing alarmingly.

Population Based Study and Global Estimates of Hearing Impairment in Schoolchildren

Hearing impairments in schoolchildren affects learning and communication. Reliable data on hearing loss prevalence in this group are necessary for planning the audiological care. Aim. To compare data from a population based study of the hearing loss prevalence in schoolchildren and estimates from the Global Burden of Disease (GBD) study in the Republic of Yemen. Materials and methods. Data extraction was performed from the GBD database on the prevalence of bilateral hearing loss &gt;20 dB among children aged 5–9 years in the Republic of Yemen. A two stage study of hearing loss prevalence among primary school students aged 6–9 years in Sana’a, Republic of Yemen, in a sample of 2200 children using screening audiometry at 20 dB at 0.5, 1, 2, and 4 kHz is school settings, followed by tonal threshold audiometry and tympanometry in a specialized clinic. Hearing loss was assessed as unilateral or bilateral when hearing thresholds were higher than 25 dB. Results. According to GBD estimates, bilateral hearing impairment in this population is 2.2%, including 1.4% of mild degree. According to the results of a Yemenian population study, mild and moderate hearing impairment was detected in 10.6%, of which 6.8% – unilateral, 3.8% – bilateral hearing loss. There were no cases of severe or profound hearing loss. The prevalence of otitis media with effusion was 6%, chronic suppurative otitis media – 1.8%, sensorineural hearing loss – 1.6%. Conclusion. Bilateral hearing impairments occur in 2.2–3.8% of primary school students, with unilateral impairments the prevalence is up to 10.6%. Of these, at least 65% have conductive hearing loss due to pathology of the middle ear. The data obtained will improve the efficiency of ear and hearing care for schoolchildren.

Elderly but could be mastoiditis?

Mastoiditis is a condition that can occur two weeks after the onset of acute suppurative otitis media. With the assistance of her daughter, an 86-year-old female patient presented to the family medicine outpatient clinic with complaints of urinary incontinence and fatigue. Although the prevalence of otitis media in the elderly population varies by country, it is generally low, ranging between 0.25 and 9%. Older patients have otalgia with or without hearing loss or symptoms. Infection can cause mastoiditis, petrositis, and labyrinthitis through adjacent structures. The aim of this case report is to emphasize the importance of the subject by evaluating the elderly patient with mastoiditis in our clinic.

Prevalence of Otitis Media in Children and Pattern of Antibiotic Prescription at a Tertiary Hospital in Makkah

Background: Otitis media (OM) is a common inflammatory disease of the middle ear and mostly affects children less than 5 years. It is divided into several disease subcategories: acute otitis media (AOM), recurrent AOM, OM with effusion (OME), and chronic otitis media (COM). This study aims to determine the otitis media and identify the manner of prescribing antibiotics used for the treatment of OM cases in children from 3 months to 5 years old in Hera General hospital in Makkah city. Methods: The samples were retrospectively conducted at a tertiary General Hospital in the western region of Saudi Arabia. 113 records met the inclusion criteria for the study. Data were analyzed using descriptive statistics (percent and frequency). For quantitative data, the chi-square test and mean were used. Results: The number of OM cases was higher in patients aged 3 years old and less among age categories. The percentage of males (54.6%) was higher than females (45.4%). Amoxicillin-clavulanate was the most used treatment of OM in the inpatient ward, outpatient, emergency, and after discharge. The protocol of treatment was mostly by prescribing both antibiotics and analgesics without requesting any further samples to investigate the type of pathogen related to this infection. Cases presented to the emergency department were discharged with an antibiotic prescription without further investigation of the records for previous infection or recurrence. Conclusions: Due to increasing the antibiotics resistance alert around the globe, we believe that OM recurrence could be one of the community-acquired infections that affect the pediatric population and lower the quality of life and need specific attention from a physician who prescribes antibiotics for OM without further investigation.

Otitis Media Prevalence in Children Below 18 Years of Age of India and the Associated Risk Factors: A Systematic Review and Meta-Analysis.

Ear ailments in children are a major public health problem in India. This systematic review and meta-analysis aim to quantitatively pool the epidemiologic evidence on the prevalence of all forms of otitis media in children of India. In this review PRISMA guidelines (preferred reporting items for systematic reviews and meta-analysis) were followed. We did extensive literature search in PubMed, Embase, Cinahl and Web of Science to identify relevant community based cross sectional studies that investigated the prevalence of otitis media in children of India. We used STATA version 16.0 software to perform meta-analysis. Six studies reporting the prevalence of otitis media in children were included in the final analysis. Based on the results of the random-effects sub-group meta-analysis model, the pooled estimated prevalence of Chronic suppurative otitis media in children of India was 3.78% (95% CI 2.72-4.84), Otitis media with effusion was found to be 2.68% (95% CI 1.80, 3.55) and Acute suppurative otitis media to be 0.55 (95% CI 0.32, 0.78). This review suggests substantial otitis media related disease burden in children of India. But due to lack of epidemiological studies, the actual disease burden remains concealed. It is imperative to promote more epidemiological studies that will aid policy makers in recommendation of preventive, diagnostic and treatment strategies for this disease.

Effect of pneumococcal conjugate vaccine on prevalence of otitis media with effusion among children in Vietnam

PurposeOtitis media with effusion (OME) is common in young children and is associated with Streptococcus pneumoniae infection. We aimed to determine the impact of pneumococcal conjugate vaccine (PCV) introduction on the prevalence of OME and OME associated with vaccine-type (VT) or non-VT. MethodsPopulation-based cross-sectional surveys were conducted in pre- (2016) and post-PCV periods (2017, 2018, and 2019) at selected communes in Nha Trang, Vietnam. For each survey, we randomly selected 60 children aged 4–11 months and 60 aged 14–23 months from each commune. Nasopharyngeal sample collection and tympanic membrane examination by digital otoscope were performed. S. pneumoniae was detected and serotyped by lytA qPCR and microarray. Odds ratios (OR) and 95% confidence intervals (CIs) were calculated using Firth’s logistic regression, stratified by age group. ResultsOver the four surveys, 2089 children had a bilateral ear examination. Compared to pre-PCV, the prevalence of OME reduced in 2018 (OR 0.51, 95 %CI 0.28–0.93) and in 2019 (OR 0.53, 95 %CI 0.29–0.97) among the <12-month-olds, but no significant reduction among the 12–23-month-olds. The prevalence of OME associated with VT pneumococcus decreased in 2018 and 2019 (2018: OR 0.14, 95 %CI 0.03–0.55; 2019: OR 0.20, 95 %CI 0.05–0.69 in the <12-months-olds, 2018: OR 0.05, 95 %CI 0.00–0.44, 2019: OR 0.41, 95 %CI 0.10–1.61 in the 12–23-months-olds). The prevalence of OME associated with non-VT pneumococcus increased in the 12–23-month-olds in 2017 (OR 3.09, 95 %CI 1.47–7.45) and returned to the pre-PCV level of prevalence in 2018 and 2019 (OR 0.94, 95 %CI 0.40–2.43 and 1.40, 95 %CI 0.63–3.49). ConclusionPCV10 introduction was associated with a reduction of OME prevalence in infants but not in older children.

Bacterial Agents Causing Chronic Suppurative Otitis Media

Background: Otitis media which is an acute or chronic inflammatory state of the middle ear may be classified as suppurative or non—suppurative.&#x0D; Methods: A total of 100 ear swabs from cases of chronic otitis media were variously collected from patients attending the ENT Clinic. Specimens were immediately transported in a transport medium to the base laboratory of the Department of Microbiology.&#x0D; Results: Out of a total number of 100 cases of chronic otitis media screened for the isolation of bacterial aetiologic agents, 8 different genera comprising 13 bacterial species were isolated. These included S. aureus (39%), Pseudomonas aeruginosa (25%), Proteus mirabilis (16%), Alcaligenes faecalis (5%) and Klebsiella aerogenes (1%). Escherichia coli, Proteus rettgeri, Staphylococcus epidermidis, and Klebsiella pneumoniae, constituted (3%), (3%), (3%) and 1% of isolates in that respective order. From the number of cases screened, it was observed that 54 (54% and 46(46%) were males and females respectively.&#x0D; Conclusion: We conclude that higher prevalence of otitis media among males than females and S. aureus has been identified as the leading pathogen in chronic otitis media.&#x0D; Keywords: Bacterial Infections, Etiology, Otitis Externa.

Otologic disorders and management strategies in Turner syndrome

Objective: To analyze the incidence and risk factors of otologic disorders in patients with Turner syndrome (TS), so as to provide management strategies for ear health. Methods: This study is a prospective study based on questionnaires and a cross-sectional study. The TS patients who visited our hospital from 2010 January to 2021 March were included (A total of 71 patients with TS were included in this study. the age of TS diagnosed was 3- to 11-year-old, age of visiting ENT department was 4- to 27-year-old) and the incidence of otologic diseases in different age groups was investigated by questionnaires. The cross-sectional study included ear morphology and auditory function assessment, and further analysis of the risk factors that related to ear disease. Prism was used for data analysis. Results: The investigation found that the incidence of acute otitis media in patients aged 3-6 and 7-12 years was higher than that of patients over 12 years old, which was 33.8%(24/71), 42.9%(30/70)and 23.5%(8/34), respectively; 21.1% (15/71) of patients were recurrent acute otitis media in patients aged 3-6 years, and about 46.6% (7/15)of them persisted beyond 6-year. The prevalence of otitis media with effusion in the three groups was 32.4%(23/71), 34.3%(24/70)and 38.2%(13/34), respectively; the recurrence rate of tympanocentesis was 100%(7/7), 42.9%(3/7)and 50.0%(1/2), which was significantly higher than that of grommet insertion. For age groups of 3-6 and 7-12 years, the prevalence of acute otitis media and secretory otitis media was lower in the X chromosome structure abnormal patients; while for patients older than 12 years, otitis media with effusion was the highest prevalence in Y-chromosome-containing karyotypes. In addition, the prevalence of acute otitis media and otitis media with effusion in patients with other system diseases were increased significantly. A cross-sectional study found that 7.0% (5/71)of the lower auricular, 4.2% (3/71)of the external auditory canal narrow, and 38.0% (27/71)of the tympanic membrane abnormality. 35.2%(25/71) had abnormal hearing, including 17 cases of conductive deafness, 6 cases of sensorineural hearing loss, and 2 cases of mixed deafness. The rest of the patients had normal hearing, but 6 of them had abnormalities in otoacoustic emission. Eustachian tube function assessment found that the eustachian tube dysfunction accounted for 38%(27/71). Hearing loss and abnormal Eustachian tube function were not significantly related to karyotype(Chi-square 2.83 and 2.84,P value 0.418 and 0.417), but significantly related to other system diseases(Chi-square 13.43 and 7.53,P value<0.001). Conclusions: The incidence of TS-related otitis media and auditory dysfunction is significantly higher than that of the general population. It not only occurs in preschool girls, but also persists or develops after school age. Accompanied by other system diseases are risk factors for ear diseases. Clinicians should raise their awareness of TS-related ear diseases and incorporate ear health monitoring into routine diagnosis and treatment.

The Indoor Environment and Otitis Media among Australian Children: A National Cross-Sectional Study

The association between the indoor environment and lifetime prevalence of otitis media (OM) in Australian children was assessed. We analysed data from a cross-sectional study of children, aged 7–11 years, performed in twelve Australian cities during 2007–2008. The main outcome was a parental report of their child’s diagnosis with OM by a doctor. Information on the indoor environment (energy sources used for heating, cooling, and cooking, pets, and second-hand smoke exposure), in the first year of life and at present, was collected from parents by a questionnaire. Multi-level logistic regression models were used to adjust for individual- and area-level confounders. Our analysis comprised 2872 children (51% female, mean age: 10.0 (SD 1.2)). Of those, 1097 (39%) were reported to have OM. Exposure to gas heating in the first year of life was significantly associated with higher odds of OM in adjusted models (OR:1.22; 95% CI: 1.00,1.47), as was current exposure to reverse-cycle air conditioning (OR: 1.52, 95% CI: 1.27,1.82). Ownership of a cat or dog at any time was also associated with high odds of OM (OR: 1.50; 95% CI: 1.17,1.92). No other significant associations were observed. In this national study of Australian children, indoor environmental exposures associated with the lifetime prevalence of OM were gas heating, reverse-cycle air conditioning and pet ownership. Exposures in both early life and later childhood may both play a role in OM.

Impact of COVID-19 on nationwide pediatric otolaryngology: Otitis media and myringotomy tube trends

PurposeThe pandemic related to the novel coronavirus (COVID-19) has led to a decrease in communicable diseases due to social distancing and mask-wearing. How have the prevalence of otitis media (OM) and its associated procedures changed during the pandemic? Study designRetrospective Cohort Study. MethodsThis is a retrospective cohort study using the Pediatric Health Information System® (PHIS) database, which consists of 48 children's hospitals. Regions were defined according to PHIS rules. We compared proportion of OM to total diagnoses codes, and collected mastoiditis, and MT placements from all encounters through January 1, 2019-June 31, 2021. ResultsIn April 2020, there was a decrease in mean proportion of OM cases per 100 hospital visits (7 v. 2, p < 0.0001) and this was sustained through 2020 and until June 2021 (6–7 v. 2–4, p < 0.05; p < 0.05). Compared to 2020, the months of April and June 2021 showed an increase in mean proportion of OM cases (6–7 v. 3–4, p < 0.05) while May did not. This relative increase in OM cases through April–June were primarily driven by the South, the Midwest, and the Northeast in April and the South and the Midwest in June. MT procedures followed similar trends. In 2020, there was no difference in mastoiditis as a proportion of OM cases compared to 2019 however there was a statistically higher rate of mastoiditis in 2020 compared to 2021. ConclusionsThe COVID-19 pandemic led to declines in OM and MT case volumes that have started to increase. A geographic relationship may exist, and this connection could be influenced by mask mandates and social distancing.

Association of Passive Smoking with Otitis Media among School Children of Eastern Nepal

Abstract Introduction Otitis media (OM) and otitis media with effusion are commonly presenting conditions in an otolaryngology clinic. Exposure to passive smoking is thought to increase the risk of OM through an effect on mucociliary clearance, decreased ciliary beat frequency, or mucous hypersecretion. Awareness among parents plays a key role in the primary prevention of the disease. Objective We aimed to identify the association of passive smoking with OM among school-going children of the eastern region of Nepal. Methods A community-based cross-sectional study was done among 663 school-going children, selected by stratified random sampling using a questionnaire. Data regarding age, gender, type of school, otological symptoms, smoking status of parents and family members, otoscopic findings, pure tone audiometry, and impedance audiometry were recorded. Results Six-hundred and sixty-three students were included in the study. OM was confirmed in 103 students (15.5%). Smoking history was present in at least one of the family members in 177 out of 663 students (26.69%) and with positive smoking history in any member of the family, OM was seen in 65 (36.7%) students (p ≤ 0.001), which suggested significant association. OM was seen in 38 students (7.8%) when there was no exposure to passive smoking. Conclusions There is a high prevalence of OM (15.5%) in school-going children. The study shows significant association between passive smoking and OM in children.

Prevalence of common bacterial etiology and antimicrobial susceptibility pattern in patients with otitis media in Duhok Province –Iraq

&nbsp;&nbsp;&nbsp;&nbsp; Otitis media is the most frequent type of ear infection. It is a major health problem for both children and adults but the proportion is different in different countries. The current study was designed to determine the frequency of bacterial isolates causing otitis media and their antimicrobial resistance profile to assess the incidence of multidrug-resistant (MDR), extensively drug-resistant (XDR), and pan drug resistance (PDR) among the isolated pathogens. Also, to determine the various risk factors (age, gender, type, and site of infection) associated with ear infection. A total of 200 ear discharge samples were collected from patients aged 1-77 years attending the Ear, Nose, and Throat (ENT) unit in Azadi Teaching Hospital in Duhok city from November 2018 to September 2019. The clinical samples were cultured and bacterial isolates were identified by standard microbiological methods then confirmed by VITEK®&nbsp;2 Compact automated system. All gram-negative bacterial isolates were studied phenotypically for Extended Spectrum Beta Lactamase production. Out of 200 ear swabs, 95% confirmed positive culture; 85.8% were bacterial isolates. From the total bacterial isolates, 57% were gram-positive bacteria, while gram-negative bacteria were 43%; with predominant of Pseudomonas aeruginosa, (22%) followed by Staphylococcus aureus (19%) and Coagulase negative Staphylococci (18%). The prevalence of otitis media was not significantly affected by gender. The majority of patients belonged to the age group (1-10) years old. 64.1% of the isolates were characterized as MDR, 31.7% were XDR, with one (0.7%) as PDR. Among these, 60.7% isolates were ESBL producers, Pseudomonas aeruginosa was the most frequent ESBL- producing isolates (45.9%), followed by Proteus spp (18.9%). The in-vitro sensitivity results indicated that Gentamycin and Ciprofloxacin were effective antibiotics in the treatment of otitis media. Additionally, Meropenem, Imipenem, Cefepime, and Azetronam were also the most effective drug against Pseudomonas aeruginosa. We concluded that the drug resistant isolates were common, worryingly high, leaving only limited drugs as a treatment choice.

Prevalence of otitis media and risk factors for sensorineural hearing loss among infants attending routine well-baby clinics in urban and rural/remote Samoa: a study protocol

Background The World Health Organization recommends newborn and infant hearing screening programs for all member states to enable early detection and intervention for children with hearing loss. Ear and hearing services are limited in the Pacific Islands, a region with one of the highest global rates of ear disease and hearing loss. Given that a significant proportion of childhood hearing loss is preventable through public health measures, collaboration with existing primary and public health platforms should reduce the prevalence of avoidable ear and hearing disorders among infants and young children. Previous work has investigated an infant ear and hearing program for child welfare clinics in an urban Pacific Island setting. The present study will build on this previous work by investigating the possibility of an Infant Ear and Hearing Program in a different Pacific Island country, and performing comparisons between urban and rural/remote populations. Methods and analysis We propose a cross-sectional study of infants attending well-baby clinics in urban (Apia), rural (Upolu), and remote (Savai’i) Samoa. All participating infants will undergo an ear examination of both ears, and as assessment of risk factors for permanent hearing loss. Ethics and and conclusions We publish these protocols to facilitate similar studies in other low- and middle-Income countries, and especially among our Pacific Island neighbours. We anticipate that 25% of infants will present with ear pathology in at least one ear, and that 25% of infants will present with at least one risk factor for permanent hearing loss. This study was approved by the Government of Samoa Ministry of Health Ethical Research Committee and the University of Queensland Medical Ethics Research Committee.

Evaluating the Frequency of Ear Problems in Patients with Cleft Lip and Palate

Background: Orofacial cleft is one of the most common congenital malformations of craniofacial region. Otitis media with effusion causing conductive hearing loss is a considerable challenge for many children with cleft lip and palate. The aim of this study was to evaluate the prevalence of hearing disorders and associated malformations in these patients. Methods: The research population consisted of patients with cleft palate, between years 2012 and 2014, who were referred to Children’s Medical Center and Vali-e-Asr hospital in Tehran, Iran. Otoscopic examination, tympanometry, pure tone audiometry and echocardiography were performed for each patient. Results: Among patients with cleft palate, 73% suffered from hearing disorders. There was no relationship between prevalence of hearing loss and sex, presence of other congenital anomalies and degree of cleft, but middle ear diseases were significantly higher in children younger than 2 years. Among patients with cleft lip or palate, 10% suffered from cleft lip, 63% suffered from cleft palate and 27% suffered from cleft lip and palate. There was at least one congenital anomaly in 53% of patients. Conclusion: This study demonstrates high prevalence of otitis media with effusion and conductive hearing loss in patients with cleft. However, audiologic problems are alleviated when patients become older.
