BMC Public Health 2024; 24:1581. [PMID: 38867184 PMCID: PMC11170825 DOI: 10.1186/s12889-024-18962-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 05/27/2024] [Indexed: 06/14/2024] Open
Abstract
BACKGROUND Acute otitis media (AOM) is a prevalent childhood acute illness, with 13.6 million pediatric office visits annually, often stemming from upper respiratory tract infections (URI) and affected by environmental factors like air pollution and cold seasons. METHODS Herein, we made use of territory-wide hospitalization data to investigate the relationships between meteorological factors, air pollutants, influenza infection, and AOM for children observed from 1998 to 2019 in Hong Kong. Quasi-Poisson generalized additive model, combined with a distributed-lag non-linear model, was employed to examine the relationship between weekly AOM admissions in children and weekly influenza-like illness-positive (ILI +) rates, as well as air pollutants (i.e., oxidant gases, sulfur dioxide, and fine particulate matter), while accounting for meteorological variations. RESULTS There were 21,224 hospital admissions due to AOM for children aged ≤ 15 years throughout a 22-year period. The cumulative adjusted relative risks (ARR) of AOM were 1.15 (95% CI, 1.04-1.28) and 1.07 (95% CI, 0.97-1.18) at the 95th percentile concentration of oxidant gases (65.9 ppm) and fine particulate matter (62.2 μg/m3) respectively, with reference set to their medians of concentration. The ARRs exhibited a monotone increasing trend for all-type and type-specific ILI + rates. Setting the reference to zero, the cumulative ARRs of AOM rose to 1.42 (95% CI, 1.29-1.56) at the 95th percentile of ILI + Total rate, and to 1.07 (95% CI, 1.01-1.14), 1.19 (95% CI, 1.11-1.27), and 1.22 (95% CI, 1.13-1.32) for ILI + A/H1N1, A/H3N2, and B, respectively. CONCLUSIONS Our findings suggested that policy on air pollution control and influenza vaccination for children need to be implemented, which might have significant implications for preventing AOM in children.

Abstract
OBJECTIVES To determine rates and risk factors of pediatric otitis media (OM) using real-world electronic health record (PEDSnet) data from January 2009 through May 2021. STUDY DESIGN Retrospective cohort study. SETTING Seven pediatric academic health systems that participate in PEDSnet. METHODS Children <6 months-old at time of first outpatient, Emergency Department, or inpatient visit were included and followed longitudinally. A time-to-event analysis was performed using a Cox proportional hazards model to estimate hazard ratios for OM incidence based on sociodemographic factors and specific health conditions. RESULTS The PEDSnet cohort included 910,265 children, 54.3% male, mean age (months) 1.3 [standard deviation (SD) 1.6] and mean follow up (years) 4.3 (SD 3.2). By age 3 years, 39.6% of children had evidence of one OM episode. OM rates decreased following pneumococcal-13 vaccination (PCV-13) and the COVID-19 pandemic. Along with young age, non-Hispanic Black/African American or Hispanic race/ethnicity, public insurance, higher family income, and male sex had higher incidence rates. Health conditions that increased OM risk included cleft palate [adjusted hazard ratio (aHR) 4.0 [95% confidence interval (CI) 3.9-4.2], primary ciliary dyskinesia [aHR 2.5 (95% CI 1.8-3.5)], trisomy 21 [aHR 2.0 (95% CI 1.9-2.1)], atopic dermatitis [aHR 1.4 (95% CI 1.4-1.4)], and gastroesophageal reflux [aHR1.5 (95% CI 1.5-1.5)]. CONCLUSIONS Approximately 20% of children by age 1 and 40% of children by age 3 years will have experienced an OM episode. OM rates decreased after PCV-13 and COVID-19. Children with abnormal ciliary function or craniofacial conditions, specifically cleft palate, carry the highest risk of OM.

Abstract
OBJECTIVE Otolaryngologists perform bilateral myringotomy and tube placement for surgical management for otitis media with effusion. This retrospective study aimed to address the extent to which the coronavirus disease 2019 pandemic and season impact the number of bilateral myringotomy and tube placement procedures performed at a tertiary care centre. METHODS A total of 1248 charts of children who underwent bilateral myringotomy and tube placement from January 2018 through February 2021 were reviewed. RESULTS The cohort included 41.6 per cent females and 58.4 per cent males, with 63.7 per cent having private insurance. The median age at surgery was 2.6 years. The spring season had the most bilateral myringotomy and tube placement procedures per week. The number of bilateral myringotomy and tube placement procedures performed per week after the onset of the coronavirus disease 2019 pandemic was significantly lower compared to the years prior. There was no difference in number of intra-operative effusions pre-pandemic versus after the pandemic onset. CONCLUSION This study sheds light on the impact of the coronavirus disease 2019 pandemic and seasonality on the rates of tympanostomy tube procedures, vital for understanding the temporality of ear infections.

Abstract
Conjunctivitis is a common multifactorial inflammatory ocular surface disease characterized by symptoms such as congestion, edema, and increased secretion of conjunctival tissue, and the potential effects of meteorological factors as well as extreme meteorological factors on conjunctivitis and their lagging effects have not been fully evaluated. We obtained the electronic case information of 59,731 outpatients with conjunctivitis from the Ophthalmology Department of the First Affiliated Hospital of Xinjiang Medical University (Urumqi, Xinjiang, China) for the period from January 1, 2013, to December 31, 2020. Meteorological data for daily mean temperature (°C), daily relative humidity (%), daily average wind speed (m/s), and atmospheric pressure (hPa) were obtained from the China Meteorological Data Sharing Service. The air pollutant data were obtained from 11 standard urban background fixed air quality monitors. A time-series analysis design and a quasi-Poisson generalized linear regression model combined with a distributed lagged nonlinear model (DLNM) were used to fit the effects of exposure to different meteorological factors and extreme weather on conjunctivitis outpatient visits. Subgroup analyses were performed on gender, age and season, and type of conjunctivitis. Univariate and multifactorial model results indicated that each 10-unit increase in mean temperature and relative humidity was associated with an increased risk of conjunctivitis outpatient visits, while each 10-unit increase in atmospheric pressure was associated with a decreased risk. The results of the extreme weather analysis suggested that extremely low levels of atmospheric pressure and relative humidity as well as extreme levels of temperature were associated with an increased risk of outpatient conjunctivitis visits, and extreme wind speeds were associated with a decreased risk. The results of the subgroup analysis suggested gender, age, and seasonal differences. We conducted the first large sample size time-series analysis in the large city furthest from the ocean in the world and confirmed for the first time that elevated mean temperature and extreme low levels of relative humidity in Urumqi were risk factors for local conjunctivitis outpatient visits, while elevated atmospheric pressure and extreme low levels of wind speed were protective factors, and there were lagged effects of temperature and atmospheric pressure. Multicenter studies with larger sample sizes are needed.

Abstract
Background Acute otitis media (AOM) may occur as a complication of viral upper respiratory infection (URI) in children. Our objective was to examine children with URI + AOM or URI alone to determine the association of infection by different common respiratory viruses with AOM. Methods Nasopharyngeal swabs were collected from March 2014 to February 2015. Quantitative PCR was then used to identify the following 10 common respiratory viruses: respiratory syncytial virus (RSV); parainfluenza viruses 1-4 (PIVs); influenza virus type A (IFVA); influenza virus type B; human rhinovirus (HRV); enterovirus; human metapneumovirus; human coronavirus OC43, 229E, NL63, and HKU1; adenovirus; and human bocavirus. Results We examined 255 children with URIs (mean age: 32.9 ± 18.7 months), and 164 (64.1%) of them tested positive for at least one respiratory virus. The most common viruses were RSV (44, 24.3%), PIVs (28, 15.5%), and IFVA (25, 13.8%). Positivity for RSV was significantly greater in the URI + AOM group than in the URI group, but these groups did not differ in infection rates for the other 9 viruses. There were also significant seasonal differences in positivity for RSV, IFVA, HRV,HBoV, PIVs and EV. Conclusion Our results indicated a relationship between infection by common respiratory viruses and AOM in children from Beijing. A URI with RSV significantly increased the risk of AOM in these children.

Abstract
BACKGROUND Cerebral venous sinus thrombosis (CVST) in children is a rare disease with a complex, multifactorial etiopathogenesis. The Polish National Health Fund (NHF) Registry [Narodowy Fundusz Zdrowia (NFZ)], contains health insurance data from all 16 national provinces, or voivodeships. This study used data from the Polish NHF Registry to evaluate 52 pediatric patients who required 78 hospital admissions for CVST from 2013 to 2020. MATERIAL AND METHODS The data in the Polish NHF Registry were acquired based on the disease code I67.6 from the International Classification of Diseases, Tenth Revision (ICD-10), and the patients' age (up to 18 years old). RESULTS We identified 78 hospitalizations of 52 pediatric patients due to CVST in Poland from 2013 to 2020 (63.5% boys and 36.5% girls, mean age 9.7±5.8 years old). The mean duration of hospitalization was 10.5±11.7 days, the mean cost of hospitalization was 3273±2191 Polish zloty (PLN). The most common age subgroup was adolescents (27%). Ten percent of patients were hospitalized in a region other than their region of residence. The duration and cost of hospitalization were positively correlated with each other (r=0.512, P<0.001). The most common type of admission was an emergency (51%), and the most common discharge was referral for further outpatient treatment (50%). CONCLUSIONS Polish registry data showed that from 2013 to 2020, CVST was more commonly diagnosed in male adolescents from 15 to 18 years of age who presented as emergency hospital admissions. There were regional differences in incidence and duration of hospital stay and healthcare costs between patients.

Abstract
This study undertook to determine the changes in the numbers of outpatient visits for various ophthalmic diseases during the COVID-19 pandemic compared with before. The monthly outpatient visits for 14 common ophthalmic diseases were enumerated based on the ICD-10 codes in Korean National Health Insurance Service data. The differences in the mean outpatient visits and disease variance 'before' and 'during COVID-19' were calculated. Subsequently, subgroup analyses according to age and sex were performed. The number of outpatient visits for conjunctivitis, scleritis & episcleritis, keratitis, cataract, diabetic retinopathy, and traumatic ophthalmic disease were lower during than before COVID-19 (all P < 0.001). The lower numbers of outpatient visits for ophthalmic disorders during COVID-19 were consistent across the age and sex subgroups. All ophthalmic diseases other than endophthalmitis showed no change of variation 'during' relative to 'before' COVID-19. In conclusion, during the COVID-19 pandemic, the ophthalmic outpatient visits decreased for infectious and inflammatory diseases, screening diseases, and traumatic diseases. However, COVID-19 is not considered to have had a significant effect on variation.

Abstract
BACKGROUND Ketorolac-refractory pain behavior following bilateral myringotomy and pressure equalization tube placement (BMT) is associated with the absence of middle ear fluid. Intraoperative fentanyl/ketorolac affords more reliable pain control than ketorolac alone. We hypothesized that middle ear condition would correlate with postoperative pain despite such combination therapy. We further sought to demonstrate seasonal variation in ear condition and its influence on pain. METHODS We conducted a single-institution retrospective cohort study of healthy children (9 months-7 years), who underwent BMT by a single surgeon from 2015 to 2020. Anesthetic care included sevoflurane/nitrous oxide/oxygen/air by mask and intramuscular fentanyl/ketorolac. Left/right middle ear fluid status was recorded at the time of BMT, and ear condition (primary exposure) was dichotomized as bilateral infected (mucoid or purulent) or normal/unilateral infected. The primary outcome was maximum postanesthesia care unit Face, Legs, Activity, Cry, and Consolability (FLACC) score: 4-10 (moderate-to-severe pain) versus 0-3 (no-to-low pain). Rescue oxycodone, acetaminophen administration, and emergence agitation were secondary outcomes. Statistical analysis incorporated generalized linear mixed-effect models (GLMMs) with random intercepts to account for clustering by anesthesia provider. A year-over-year monthly time-series analysis was conducted using an autoregressive integrated moving average (ARIMA) regression model. RESULTS Excluding recurrent cases, 1149 unique evaluable subjects remained. Bilateral infection prevalence was 39.8% (457/1149; 95% confidence interval [CI], 37.0-42.6). Probability of moderate-to-severe pain behavior was 23.5% (270/1149; 95% CI, 21.1-26.0) overall. Compared to patients with bilateral infected middle ears, those with normal/unilateral infected ears were more likely to have a FLACC score ≥4 (26.7% [185/692] versus 18.6% [85/457]; odds ratio [95% CI], 1.7 [1.2-2.3]; P = .002). Variability in pain outcome explained by the multivariable GLMM was 4.7%. Fentanyl dose response was evidenced by oxycodone administration differences ( P ≤ 0.002). Moderate-to-severe pain and emergence agitation were more likely with reduced fentanyl dosing. Bilateral infection prevalence exhibited seasonality, peaking in March and nadiring in July. However, pain outcomes did not vary by season. CONCLUSIONS Normal/unilateral infected ears at time of pediatric BMT are associated with higher incidence of moderate-to-severe postoperative pain following intraoperative fentanyl/ketorolac administration, but the predictive value of ear condition on pain is limited. Infections were less common in the summer.

Abstract
This study aimed to investigate the change in the incidence and variance of otorhinolaryngologic diseases during the coronavirus disease 19 (COVID-19) pandemic. The entire Korean population (~50 million) was evaluated for the monthly incidence of 11 common otorhinolaryngologic diseases of upper respiratory infection (URI), influenza, acute tonsillitis, peritonsillar abscess, retropharyngeal and parapharyngeal abscess, acute laryngitis and bronchitis, stomatitis and related lesions, acute sinusitis, rhinitis, otitis media, and dizziness from January 2018 through March 2021 using the International Classification of Disease (ICD)-10 codes with the data of the Korea National Health Insurance Service. The differences in the mean incidence of 11 common otorhinolaryngologic diseases before and during COVID-19 were compared using the Mann-Whitney U test. The differences in the variance of incidence before and during COVID-19 were compared using Levene's test. The incidence of all 11 otorhinolaryngologic diseases was lower during COVID-19 than before COVID-19 (all p < 0.05). The variations in disease incidence by season were lower during COVID-19 than before COVID-19 for infectious diseases, including URI, influenza, acute tonsillitis, peritonsillar abscess, retropharyngeal and parapharyngeal abscess, acute laryngitis and bronchitis, acute sinusitis, and otitis media (all p < 0.05), while it was not in noninfectious diseases, including stomatitis, rhinitis, and dizziness. As expected, the incidences of all otorhinolalryngolgic diseases were decreased. Additionally, we found that seasonal variations in infectious diseases disappeared during the COVID-19 pandemic, while noninfectious diseases did not.

Abstract
Objective To identify characteristics of acute otitis media (AOM) at primary care presentation associated with TT placement and outcomes. Methods A retrospective cohort study of pediatric patients (birth—12 years old) with AOM at an academic primary care pediatric practice and affiliated tertiary referral free‐standing Children's hospital from August 1, 2017 to December 31, 2019 was performed. The outcomes measured were TT placement, postoperative otorrhea, need for additional tube placement, and other complications (i.e., perforation and/or granulation). Results The 3189 patients were included, 484 of whom were referred to otolaryngology. Multivariate logistic regression analysis revealed that a greater number of AOM episodes diagnosed at primary care was associated with tube placement (OR = 1.21; 95% CI, 1.04–1.41, p = .02). Of the 336 patients who received tubes, older age at first AOM diagnosis was associated with postoperative otorrhea (OR = 1.02; 95% CI, 1.01–1.03; p = .001) and additional tube placement (OR = 1.03; 95% CI, 1.02–1.04; p < .001). Older age was also associated with other complications (OR = 1.02; 95% CI, 1.01–1.03; p = .001) by univariate analysis. Additionally, postoperative otorrhea was more common among patients who first received an AOM diagnosis at primary care in the spring (OR = 2.69; 95% CI, 1.37–5.29; p = .004), summer (OR = 2.88; 95% CI, 1.46–5.69; p = .002), and fall (OR = 2.18; 95% CI, 1.20–3.96; p = .01) seasons. Conclusions Clinical data from pediatric primary care visits found older age at first AOM diagnosis and having a first AOM diagnosis outside of winter to be associated with a more complicated eventual disease course. Level of evidence 3—cohort study.

Abstract
Otitis media (OM) encompasses a spectrum of clinical presentations ranging from the readily identifiable Acute OM (AOM), which is characterised by otalgia and fever, to chronic otitis media with effusion (COME) where impaired hearing due to middle ear effusion may be the only clinical symptom. Chronic suppurative OM (CSOM) presents as a more severe form of OM, involving perforation of the tympanic membrane. The pathogenesis of OM in these varied clinical presentations is unclear but activation of the innate inflammatory responses to viral and/or bacterial infection of the upper respiratory tract performs an integral role. This localised inflammatory response can persist even after pathogens are cleared from the middle ear, eustachian tubes and, in the case of respiratory viruses, even the nasal compartment. Children prone to OM may experience an over exuberant inflammatory response that underlies the development of chronic forms of OM and their sequelae, including hearing impairment. Treatments for chronic effusive forms of OM are limited, with current therapeutic guidelines recommending a "watch and wait" strategy rather than active treatment with antibiotics, corticosteroids or other anti-inflammatory drugs. Overall, there is a clear need for more targeted and effective treatments that either prevent or reduce the hyper-inflammatory response associated with chronic forms of OM. Improved treatment options rely upon an in-depth understanding of OM pathogenesis, particularly the role of the host innate immune response during acute OM. In this paper, we review the current literature regarding the innate immune response within the middle ear to bacterial and viral otopathogens alone, and as co-infections. This is an important consideration, as the role of respiratory viruses as primary pathogens in OM is not yet fully understood. Furthermore, increased reporting from PCR-based diagnostics, indicates that viral/bacterial co-infections in the middle ear are more common than bacterial infections alone. Increasingly, the mechanisms by which viral/bacterial co-infections may drive or maintain complex innate immune responses and inflammation during OM as a chronic response require investigation. Improved understanding of the pathogenesis of chronic OM, including host innate immune response within the middle ear is vital for development of improved diagnostic and treatment options for our children.

Abstract
OBJECTIVES To explore the impact of COVID-19 on the management and outcomes of acute paediatric mastoiditis across the UK. DESIGN National retrospective and prospective audit. SETTING 48 UK secondary care ENT departments. PARTICIPANTS Consecutive children aged 18 years or under, referred to ENT with a clinical diagnosis of mastoiditis. MAIN OUTCOME MEASURES Cases were divided into Period 1 (01/11/19-15/03/20), before the UK population were instructed to reduce social contact, and Period 2 (16/03/20-30/04/21), following this. Periods 1 and 2 were compared for population variables, management and outcomes. Secondary analyses compared outcomes by primary treatment (medical/needle aspiration/surgical). RESULTS 286 cases met criteria (median 4 per site, range 0-24). 9.4 cases were recorded per week in period 1 versus 2.0 in period 2, with no winter increase in cases in December 2020-Febraury 2021. Patient age differed between periods 1 and 2 (3.2 vs 4.7 years respectively, p < 0.001). 85% of children in period 2 were tested for COVID-19 with a single positive test. In period, 2 cases associated with P. aeruginosa significantly increased. 48.6% of children were scanned in period 1 vs 41.1% in period 2. Surgical management was used more frequently in period 1 (43.0% vs 24.3%, p = 0.001). Treatment success was high, with failure of initial management in 6.3%, and 30-day re-admission for recurrence in 2.1%. The adverse event rate (15.7% overall) did not vary by treatment modality or between periods 1& 2. CONCLUSION The COVID-19 pandemic led to a significant change in the presentation and case mix of acute paediatric mastoiditis in the UK.

Antibiotic Prescribing for Acute Respiratory Tract Infections During Telemedicine Visits Within a Pediatric Primary Care Network. Acad Pediatr 2021; 21:1239-1243. [PMID: 33741531 DOI: 10.1016/j.acap.2021.03.008] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Revised: 02/28/2021] [Accepted: 03/12/2021] [Indexed: 12/12/2022]
Abstract
OBJECTIVE Regulatory and payment changes associated with COVID-19 facilitated wide-spread use of telehealth within pediatric primary care starting in March 2020. Given prior quality concerns about antibiotic management for children during telemedicine visits outside of primary care, we sought to examine acute respiratory tract infection (ARTI) visit volume and antibiotic management for children via telemedicine integrated within pediatric primary care. METHODS Using electronic health record data from 47 practices within a large pediatric primary care network, we identified visits for ARTI from April to September 2020. For these visits, we categorized antibiotic management consistent with clinical guidelines as guideline concordant. We compared telemedicine and in-person visit guideline-concordant antibiotic management, diagnoses, and antibiotic prescribing using chi-square tests and examined trends over time using descriptive statistics. Antibiotic stewardship during the study period included learning collaborative videoconferences and sharing of clinic and clinician-level metrics through an interactive dashboard. RESULTS During the 6-month period, 8332 ARTI visits were identified, with 3003 (36%) via telemedicine. Guideline-concordant antibiotic management occurred in 92.5% of telemedicine visits compared to 90.7% of in-person office visits (P = .004). Telemedicine ARTI visits receiving diagnoses of acute otitis media or streptococcal pharyngitis declined from peak of 52% (May) to 7% (September). Guideline-concordant antibiotic management of sinusitis and viral ARTI during telemedicine visits increased from 88% (April) to 97% (September). CONCLUSION With active antibiotic stewardship, pediatricians practicing within certified medical homes consistently delivered highly guideline-concordant care for ARTIs to their patient population via telemedicine integrated into primary care.

Abstract
Objective The identification of aerosol-generating procedures (AGPs) is important during the current SARS-CoV-2 pandemic due to aerosol-mediated virus transmission. Aerosol measurement during clinical procedures using particle counting may be confounded by variable natural background aerosol levels or limited by partial volume sampling. The study objective was to quantify any significant aerosol generated from simulated suction clearance procedures. Study Design Prospective quantification of aerosol generation during clinical suction simulation. Setting Clean chamber. Methods We created a clean environment for particle counting in a transparent neutralized polypropylene chamber. Air was passed through a HEPA 14 class filter to maintain a constant chamber inlet pressure. An optical particle counter was connected in line to the chamber exhaust vent to measure all of the vented particles. The chamber background count was 1 particle ≥0.3 µm per 15 minutes at a flow rate of 1 chamber air change per minute. We used this system to quantify very low aerosol counts generated from suction clearance of a silicone ear canal and at an open air-fluid interface. Results No clinically significant aerosol generation was found by particle counting of the whole chamber air volume during simulated suction procedures. Conclusion Simulated ear suction clearance and air-fluid interface suction does not generate any significant aerosol. It appears likely that any aerosol potentially generated at the suction tube tip is entrained by incoming air flow. This is the first study to quantify aerosols generated by suction in a controlled environment; further research is required to determine its clinical implications.

Abstract
Objective To compare both approaches for the treatment of nonsevere acute otitis media (AOM) in Iran. Methods This randomized clinical trial was performed at a pediatric infectious diseases clinic in Buali tertiary hospital in Sari, north of Iran, from 2016 to 2018. All participants in this study were previously healthy children with AOM diagnosis, who were 6 months to 6 years old. The patients were randomly assigned into two groups: the intervention (80 mg/kg/day amoxicillin for 7-10 days) and the control group (watchful waiting approach). AOM recovery and adverse drug reactions were evaluated after 72 hours, and the patients were followed for the frequency of AOM and middle ear effusion 1 and 3 months' postintervention. Results A total of 396 children have participated in this study. AOM recovery was significantly different in the two groups (73% vs. 44% in the intervention and control groups, respectively). Recurrence of AOM and middle ear effusion (MEE) persistence, one month following the intervention, have not shown any significant differences between the two groups. However, the AOM recurrence between 1 and 3 months was more frequent in the control group. The frequency of diarrhea was also higher in the intervention group compared to the control but no significant difference was found between the two groups regarding vomiting and skin rash. Conclusion The faster recovery from AOM is achieved when an antibiotic treatment regimen is applied, although the risk of potential side effects should be considered.

Abstract
BACKGROUND/OBJECTIVE Traditional sources cite seasonal patterns for common infectious diseases, often based on microbiologic data, but little is known about cyclical trends in clinically diagnosed infectious conditions in the emergency department (ED). We leveraged the publicly available Nationwide Emergency Department Sample database to measure the seasonality of the most common pediatric infectious diseases diagnosed in US EDs. METHODS We searched the Nationwide Emergency Department Sample database to identify infectious diagnoses comprising at least 1% of all diagnosis codes ascribed to patients 21 years and younger in US EDs from 2009 to 2013. We used Fourier regression to examine seasonal trends in disease and calculated the peak-to-nadir ratio for each infectious condition. RESULTS Over 20% of pediatric visits during the study period were for infectious conditions. Upper respiratory infection, otitis media, gastroenteritis, urinary tract infection/pyelonephritis, cellulitis/abscess, and pneumonia showed a seasonal pattern that matched trends found in prior regional or microbiologic-based studies. The strongest seasonal trend as measured by goodness of model fit was found in pneumonia (peak-to-nadir incidence ratio of 2.7), followed by otitis media (2.0), cellulitis/abscess (2.0), gastroenteritis (1.6), upper respiratory infection (3.2), and urinary tract infection/pyelonephritis (1.4). Pharyngitis did not show a strong seasonal trend. CONCLUSIONS Many of the most common pediatric infectious diseases diagnosed in US EDs exhibited seasonal patterns. Large administrative databases can be used to track seasonal disease patterns, with the advantage that they reflect clinician diagnosis beyond microbiologic confirmation. This methodology could aid in resource planning, infection control, and public health educational initiatives.

Abstract
Objectives: To present the otologic findings of a patient with COVID-19 and complicated acute otitis media, evaluate for the presence of SARS-CoV-2 in middle ear fluid, and assess whether suctioning of middle ear fluid may be aerosol- generating. Methods: The case of a man with SARS-CoV-2 infection and complicated acute otitis media with facial paralysis is presented to illustrate unique clinical decisions made in context of the COVID-19 pandemic. A cadaveric temporal bone was used to simulate droplet spread during suctioning of fluorescein-labelled middle ear fluid and visualized with a blue-light filter. Results: A 23-year-old male who presented with complicated acute otitis media with facial paralysis was found to have an acute infection with SARS-CoV-2, with positive viral PCR of nasopharyngeal swab, and a negative PCR of the middle ear fluid. He was placed on isolation precautions and treated with myringotomy, topical and systemic antibiotics, and antivirals. Consistent with observations during endonasal suctioning, suctioning of middle ear fluid was not found to be aerosol or droplet generating. Conclusion: The case of a patient with active COVID-19 presenting with complicated acute otitis media in whom middle ear fluid was sampled to evaluate the etiology of the infection and the potential middle ear predilection of SARS-CoV-2 is described. This study has implications for the clinical management of patients with both known and unknown SARS-CoV-2 infection who present with ear disease. While middle ear suctioning may not be aerosol-generating, the risk of coughing or prolonged close contact requires heightened precautions during otologic procedures in patients with suspected or confirmed COVID-19.

Abstract
INTRODUCTION Nasopharyngeal cultures are commonly used to determine the causative bacteria in upper airway infections. However, several bacteria can occupy the nasopharynx simultaneously and most healthy children are asymptomatic carriers of presumptive pathogens. This makes the interpretation of nasopharyngeal cultures difficult. Knowledge about which bacteria reside in the nasopharynx can assist the physician in the choice of antibiotic treatment and might also predict the risk of complications. Today, little is known about how nasopharyngeal cultures are being used in clinical practice. OBJECTIVES The aim of this study was to explore how nasopharyngeal cultures are used in clinical practice, when and why they are performed, what they show, and what impact they have on the treatment of the patient. METHODS The results of all nasopharyngeal cultures taken from children aged 0-12 years in the county of Skåne, Sweden, during 2018 were obtained. Medical charts from hospitals and primary care centres were used to determine why the cultures were taken and whether they resulted in a change of treatment. RESULTS During 2018, 2200 nasopharyngeal cultures were taken, most of them during the winter season. Forty-one percent of children had on-going antibiotic treatment or had been treated with antibiotics in the previous two months. Acute otitis media (AOM) was the most common reason for taking a culture. The most frequently identified bacteria were Moraxella catarrhalis and Haemophilus influenzae. There was a positive correlation between M. catarrhalis on one hand and Streptococcus pneumoniae and H. influenzae on the other. Overall, bacterial resistance was rare. The presence of beta-lactamase negative ampicillin resistant H. influenzae was associated with recent or on-going antibiotics, whereas S. pneumoniae with decreased penicillin susceptibility were found less frequently in the same group of children. A positive culture resulted in a change of treatment in 29% of the cases. CONCLUSION Apart from playing a confirmatory role and monitoring the incidence of resistant bacteria, almost a third of the nasopharyngeal cultures analysed in this study contributed to decision-making. It therefore appears that bacterial sampling have a role in clinical practice. It would be valuable to study more closely why nasopharyngeal cultures are taken in during AOM and how the result affects the treatment.

Abstract
Background: Studies of nasopharyngeal secretions serve as reliable surrogate to evaluate the involvement of viruses in acute otitis media (AOM) and upper/lower respiratory tract infections (URIs/LRIs). We explored nasopharyngeal viral studies from children with uncomplicated AOM and examined their cost-effectiveness in relation to their age. Methods: We identified children aged 0–6 years admitted to our pediatrics department in a university-affiliated, secondary hospital with uncomplicated AOM and concurrent URI/LRI between 2012 and 2017, during October–April, when viral studies are performed. Studies were performed either using antigen detection tests, for respiratory syncytial virus (RSV) and influenza A/B (2012–2016) and for a variety of other common respiratory viruses, utilizing multiplex polymerase chain reaction assays (2017). Results: A total of 249 children were included (median age: 15 months). In 88 (35%) children, viral studies were positive, most of them in children ⩽24 months (78, 89%). RSV was positive in 52 (59%) children, followed by influenza A and B, in 11 (13%) and 5 (6%) children, respectively. First year switch to a molecular assay, 4.5-fold more expensive, resulted in a statistically significant higher yield: 69% positive results in ⩽24 months, and 66% in those aged ⩽12 months (p < 0.05). In those ⩽24 months, US$23 and US$95 were spent for one positive test in the antigen detection years and the polymerase chain reaction year, respectively, whereas in those >24 months, US$83 and US$878 were invested for one positive test in the same year, respectively. Conclusion: In cost-effectiveness terms, the greatest benefit of nasopharyngeal studies was highest in children ⩽24 months.

Abstract
OBJECTIVE Complications due to acute otitis media (AOM), while rare, are associated with significant morbidity and are not well characterized from an epidemiological perspective. We analyze the pattern of presentation and emergency department (ED) utilization in patients with AOM and associated complications. STUDY DESIGN Retrospective analysis of the Nationwide Emergency Department Sample (NEDS) from 2009 to 2011. SETTING Emergency Department. PATIENTS Patients who presented with a primary diagnosis of AOM or acute mastoiditis. INTERVENTION Diagnostic. MAIN OUTCOME MEASURES NEDS was queried for patient encounters with a diagnosis of AOM or acute mastoiditis based on ICD-9 codes. Complications of severe infection, including petrositis, Gradenigo's syndrome, facial paresis, labyrinthitis, meningitis, intracranial abscess, venous sinus thrombosis, and cerebrospinal fluid leak, were assessed. Weighted estimates for demographics, types of complications, socioeconomic status, and trends over time were extracted. RESULTS A weighted total of 5,811,127 ED visits were identified. The majority of patients were less than 18 years old (79.9%) with an average age of 10.1 years. Most were discharged (99.4%). There were 15,243 (0.26%) patients who presented with a complication. The most common complications were acute mastoiditis (0.16%), labyrinthitis (0.06%), and facial paresis (0.03%). Compared with patients with uncomplicated AOM, patients with complicated AOM were older (37 vs. 10-yr old), insured by Medicare (18% vs. 2.1%), and more likely to be admitted (43.6% vs. 0.4%) (p < 0.0001, for all comparisons). CONCLUSIONS ED visits related to AOM or mastoiditis are common and complications are rare. An in-depth analysis on a national level is useful for assessing healthcare utilization trends.

Abstract
BACKGROUND It is a known fact that bacterial or viral acute otitis media occurs more frequently in the winter months. Only a few older studies on seasonal differences in middle ear findings are available. These studies are based solely on tympanography, without correlation to intraoperative middle ear findings. This study addresses the question of whether seasonal differences can be found in the preoperative tympanogram and in the corresponding intraoperative findings in children with chronic middle ear problems. PATIENTS AND METHODS This retrospective study included patients who had undergone myringotomy with or without tympanostomy tube insertion at the Charité-Universitätsmedizin Berlin between January and December 2011. Corresponding to the catarrhal phases, winter months were defined as those from November to April; summer months from May to October. The preoperative tympanogram and the documented intraoperative middle ear finding were statistically analyzed for seasonal differences. RESULTS A total of 654 ears from 206 male and 127 female patients with mean age 3.7 ± 2.5 years were analyzed. In the majority of cases, a type B tympanogram was found (n = 376; 57.5%), whereas the middle ear was filled with air in 19.1% of cases. No significant seasonal differences were found for either the intraoperative middle ear findings or the preoperative tympanograms (p > 0.05). CONCLUSION For children with a typical history of chronic otitis media without effusion and chronic tube ventilation dysfunction, myringotomy with or without tympanostomy tube insertion is indicated independently of the season. The results indicate that a wait-and-see approach with hope of improvement during the summer months is not rational.

Abstract
INTRODUCTION Varicella is a highly contagious infection that can lead to serious complications, particularly in high-risk groups; however, it is vaccine preventable. Disease awareness and understanding of the disease burden can strongly influence vaccine coverage. This review provides insight into the current epidemiology and the importance of varicella from both public health and economic perspectives across the Asia-Pacific (APAC) region. Areas covered: A systematic literature review was conducted to identify studies on the incidence, seroprevalence, fatality rate and complication rate of varicella. Economic burden studies were also captured. Altogether, 125 studies were identified across the region; these were supplemented by government reports (gray data). Reported vaccine coverage varied from 2.8% to 97%; a key influencing factor was inclusion of the varicella vaccine in national immunization programs. In general, varicella incidence in the unvaccinated population was highest in children ≤5 years old and seroprevalence increased with age. Economic analyses highlighted the cost-saving potential of vaccination programs, especially from a societal perspective. Expert opinion: Varicella-related data varied greatly across the APAC region, highlighting the need to better understand the burden of varicella in this area, and particularly identified the need for better surveillance and reporting.

Abstract
INTRODUCTION Xylitol (or 'birch sugar') is a naturally occurring sugar with antibacterial properties that has been used as a natural non-sugar sweetener in chewing gums, confectionery, toothpaste and medicines. In this preventative randomised trial, xylitol will be tested for the prevention of acute otitis media (AOM), a common and costly condition in young children. The primary outcome will be the incidence of AOM. Secondary outcomes will include upper respiratory tract infections (URTIs) and dental caries. METHODS AND ANALYSIS This study will be a pragmatic, blinded (participant and parents, practitioners and analyst), two-armed superiority, placebo-controlled randomised trial with 1:1 allocation, stratified by clinical site. The trial will be conducted in the 11 primary care group practices participating in the TARGet Kids! research network in Canada. Eligible participants between the ages of 2-4 years will be randomly assigned to the intervention arm of regular xylitol syrup use or the control arm of regular sorbitol use for 6 months. We expect to recruit 236 participants, per treatment arm, to detect a 20% relative risk reduction in AOM episodes. AOM will be identified through chart review. The secondary outcomes of URTIs and dental caries will be identified through monthly phone calls with specified questions. ETHICS AND DISSEMINATION Ethics approval from the Research Ethics Boards at the Hospital for Sick Children and St. Michael's Hospital has been obtained for this study and also for the TARGet Kids! research network. Results will be submitted for publication to a peer-reviewed journal and will be discussed with decision makers. TRIAL REGISTRATION NUMBER NCT03055091; Pre-results.

Abstract
Background Health care and public health professionals rely on accurate, real-time monitoring of infectious diseases for outbreak preparedness and response. Early detection of outbreaks is improved by systems that are comprehensive and specific with respect to the pathogen but are rapid in reporting the data. It has proven difficult to implement these requirements on a large scale while maintaining patient privacy. Objective The aim of this study was to demonstrate the automated export, aggregation, and analysis of infectious disease diagnostic test results from clinical laboratories across the United States in a manner that protects patient confidentiality. We hypothesized that such a system could aid in monitoring the seasonal occurrence of respiratory pathogens and may have advantages with regard to scope and ease of reporting compared with existing surveillance systems. Methods We describe a system, BioFire Syndromic Trends, for rapid disease reporting that is syndrome-based but pathogen-specific. Deidentified patient test results from the BioFire FilmArray multiplex molecular diagnostic system are sent directly to a cloud database. Summaries of these data are displayed in near real time on the Syndromic Trends public website. We studied this dataset for the prevalence, seasonality, and coinfections of the 20 respiratory pathogens detected in over 362,000 patient samples acquired as a standard-of-care testing over the last 4 years from 20 clinical laboratories in the United States. Results The majority of pathogens show influenza-like seasonality, rhinovirus has fall and spring peaks, and adenovirus and the bacterial pathogens show constant detection over the year. The dataset can also be considered in an ecological framework; the viruses and bacteria detected by this test are parasites of a host (the human patient). Interestingly, the rate of pathogen codetections, on average 7.94% (28,741/362,101), matches predictions based on the relative abundance of organisms present. Conclusions Syndromic Trends preserves patient privacy by removing or obfuscating patient identifiers while still collecting much useful information about the bacterial and viral pathogens that they harbor. Test results are uploaded to the database within a few hours of completion compared with delays of up to 10 days for other diagnostic-based reporting systems. This work shows that the barriers to establishing epidemiology systems are no longer scientific and technical but rather administrative, involving questions of patient privacy and data ownership. We have demonstrated here that these barriers can be overcome. This first look at the resulting data stream suggests that Syndromic Trends will be able to provide high-resolution analysis of circulating respiratory pathogens and may aid in the detection of new outbreaks.

Abstract
Background Acute otitis media (AOM) is the most common cause of pediatric medical visits and antibiotic prescriptions worldwide, but its current impact on the US healthcare system is not clear. The aim of this study was to investigate changes in the incidence of AOM from 2008, just before 13-valent pneumococcal conjugate vaccine was introduced, to 2014 using US insurance records in the Truven MarketScan® database. The study also examined the costs associated with index AOM events during the two most recent years for which data were available (2013–2014). Methods AOM cases in the MarketScan database during 2008–2014 were identified using ICD9 diagnosis codes 381.xx and 382.xx. Incidence rates of healthcare utilization related to the index AOM episode were calculated using the annual number of enrolled person-years as the denominator and the number of individuals with AOM as the numerator. AOM-associated costs were calculated as the mean payment per episode during the 2 years from 2013 to 2014. Results The overall annual rate of AOM-related healthcare utilization was 60.5 per 1000 person-years and changed little from 2008 to 2014 (range, 58.4–62.6). Most of this was due to office/outpatient visits (55.7 [range, 52.0–58.8] per 1000 person-years). Emergency department/urgent care visits (4.7 [range 3.7–6.3] per 1000 person-years) and hospitalization (0.0 [range, 0.0–0.1] per 1000 person-years) contributed little. The rate of AOM-related healthcare utilization per 1000 person-years was highest in the youngest children and declined with age (474.3 for < 1 year, 503.9 for 1 year, 316.3 for 2–4 years, 94.9 for 5–17 years, 33.1 for 18–49 years, 28.6 for 50–64 years, 23.7 for 65–74 years, 20.2 for 75–84 years, and 16.1 for ≥85 years). The mean cost per AOM episode in 2013–2014 (95% confidence interval) was $199.0 (198.4–199.6) for office or outpatient visits, $329.6 (328.2–331.0) for emergency department/urgent care visits, and $1592.9 (1422.0–1763.8) for hospitalization. Conclusions In the US, AOM-associated healthcare utilization and costs remain substantial. More effective preventive measures such as new vaccines are needed to reduce the burden of AOM.

Abstract
BACKGROUND This is an update of a Cochrane review first published in The Cochrane Library in Issue 4, 2008 and previously updated in 2011.Acute suppurative otitis media is one of the most common infectious diseases in childhood. Recurrent acute otitis media is defined for the purposes of this review as either three or more acute infections of the middle ear cleft in a six-month period, or at least four episodes in a year. Strategies for managing the condition include the assessment and modification of risk factors where possible, repeated courses of antibiotics for each new infection, antibiotic prophylaxis and the insertion of ventilation tubes (grommets). OBJECTIVES To establish whether grommet insertion reduces the frequency of episodes of recurrent acute otitis media and the proportion of symptomatic children. SEARCH METHODS The Cochrane Ear, Nose and Throat Disorders Group (CENTDG) Trials Search Co-ordinator searched the CENTDG Trials Register; Central Register of Controlled Trials (CENTRAL 2014, Issue 10); PubMed; EMBASE; CINAHL; Web of Science; Clinicaltrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 6 November 2014. SELECTION CRITERIA Randomised controlled trials comparing grommet insertion versus control (antibiotics/other treatments/no treatment) for recurrent acute otitis media in children aged from 0 to 16 years. DATA COLLECTION AND ANALYSIS Two authors independently selected studies. Three authors independently assessed study quality and extracted data. We synthesised data descriptively. MAIN RESULTS Two randomised controlled trials with a total of 148 participants are included in this review. The overall risk of bias in the studies is unclear.The first study randomised 95 children to grommets or control (antibiotic treatment of acute otitis media episodes). For the primary outcome, this study showed that grommet insertion leads to a mean reduction of 1.5 episodes of acute otitis media in the first six months after treatment. In six months of follow-up significantly more children in the grommet group had no episodes of acute otitis media (P value < 0.001). Complications of surgery included grommet blockage with acute otitis media requiring re-operation within six months in 3/54 children who underwent grommet insertion. Adverse effects were not documented in the control group. The following pre-defined secondary outcomes were not reported: change in symptom scores for otalgia or otorrhoea, alteration in the frequency of otalgia or otorrhoea, and number of days at nursery or school lost secondary to acute otitis media.The second study reported on 53 of 68 children who were randomised to grommet insertion or six months of once a day sulfamethoxazole and trimethoprim antibiotic prophylaxis. There was no significant difference in the primary outcome, number of episodes of acute otitis media, during the six-month follow-up between grommet insertion and antibiotic treatment groups (64.5% in the surgical group versus 45.4% in the antibiotic group had no recurrence, P value = 0.4). Two participants underwent grommet re-insertion to replace extruded tubes during the follow-up period. The only other adverse effect reported was the development of a skin rash in two patients in the medical group. Other pre-defined secondary outcome measures were not reported. The study has a high risk of bias and the results should be interpreted cautiously. AUTHORS' CONCLUSIONS Grommets significantly increase the number of acute otitis media-free children in the first six months after insertion compared to children who receive no treatment. Grommet insertion maybe of equivalent efficacy to once a day antibiotic prophylaxis. Further research is required to confirm the advantage of grommets over no treatment, investigate the effect beyond six months, compare grommet effectiveness against alternative active treatments and confirm the low risk of adverse effects compared to no treatment and all active treatments in recurrent acute otitis media. In the interim clinicians should consider the possible adverse effects of grommet insertion and alternative treatments before recommending surgery.

Abstract
Objectives. To evaluate the effect of pneumococcal conjugate vaccine (PCV13) on the burden of acute otitis media (AOM) and to evaluate the characteristics of AOM versus otitis media with effusion (OME) in the 2 PCV periods. Methods. A cohort of fully vaccinated children aged 18 to 60 months diagnosed with AOM from 2006 to 2015 was identified. Patients with otorrhea/bulging tympanic membrane were considered as true AOM, while those without bulging/otorrhea were considered to have OME. Burden of true AOM in the PCV7 and PCV13 periods and clinical features of true AOM versus OME were compared. Results. Of 393 episodes in our cohort, 50.8% occurred in PCV7 period. Burden of true AOM in the 2 PCV groups was similar: 26% in PCV7 versus 26.4% in PCV13 (odds ratio [OR] = 1.02, 95% confidence interval [CI] = 0.65-1.60). Factors significantly associated with OME were cold season (OR = 1.54, 95% CI = 1.04-2.4), fever (OR = 2.05, 95% CI = 1.29-3.3), and recurrence (OR = 2.24, 95% CI = 1.22-4.09). No complications of AOM were identified. Majority episodes were treated with antibiotics. Conclusion. Unlike the role of PCV13 in reducing invasive pneumococcal disease, its effect on reducing the burden of AOM is minimal as compared with PCV7. With regard to characteristics of AOM versus OME, findings of tympanic membrane should be used to suggest a diagnosis of AOM, instead of occurrence of fever or recurrence of AOM episodes. Using this approach would help in guiding the use of antibiotics appropriately.

INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2017; 61:1749-1764.

Abstract
AbstractOtitis media (OM) is a very common disease in children, which results in a significant economic burden to the healthcare system for hospital-based outpatient departments, emergency departments (EDs), unscheduled medical examinations, and antibiotic prescriptions. The aim of this retrospective observational study is to investigate the association between climate variables, air pollutants, and OM visits observed in the 2007-2010 period at the ED of Cuneo, Italy. Measures of meteorological parameters (temperature, humidity, atmospheric pressure, wind) and outdoor air pollutants (particulate matter, ozone, nitrous dioxide) were analyzed at two statistical stages and in several specific steps (crude and adjusted models) according to Poisson's regression. Response variables included daily examinations for age groups 0-3, 0-6, and 0-18. Control variables included upper respiratory infections (URI), flu (FLU), and several calendar factors. A statistical procedure was implemented to capture any delayed effects. Results show a moderate association for temperature (T), age 0-3, and 0-6 with P < 0.05, as well as nitrous dioxide (NO2) with P < 0.005 at age 0-18. Results of subsequent models point out to URI as an important control variable. No statistical association was observed for other pollutants and meteorological variables. The dose-response models (DLNM-final stage) implemented separately on a daily and hourly basis point out to an association between temperature (daily model) and RR 1.44 at age 0-3, CI 1.11-1.88 (lag time 0-1 days) and RR 1.43, CI 1.05-1.94 (lag time 0-3 days). The hourly model confirms a specific dose-response effect for T with RR 1.20, CI 1.04-1.38 (lag time range from 0 to 11 to 0-15 h) and for NO2 with RR 1.03, CI 1.01-1.05 (lag time range from 0 to 8 to 0-15 h). These results support the hypothesis that the clinical context of URI may be an important risk factor in the onset of OM diagnosed at ED level. The study highlights the relevance of URI as a control variable to be included in the statistical analysis in association with meteorological factors and air pollutants. The study also points out to a moderate association of OM with low temperatures and NO2, with specific risk factors for this variable early in life. Further studies are needed to confirm these findings, particularly with respect to air pollutants in larger urban environments.

Abstract
Objective To perform a comprehensive review of the literature from July 2011 until June 2015 on the virology and bacteriology of otitis media in children. Data Sources PubMed database of the National Library of Medicine. Review Methods Two subpanels comprising experts in the virology and bacteriology of otitis media were created. Each panel reviewed the relevant literature in the fields of virology and bacteriology and generated draft reviews. These initial reviews were distributed to all panel members prior to meeting together at the Post-symposium Research Conference of the 18th International Symposium on Recent Advances in Otitis Media, National Harbor, Maryland, in June 2015. A final draft was created, circulated, and approved by all panel members. Conclusions Excellent progress has been made in the past 4 years in advancing our understanding of the microbiology of otitis media. Numerous advances were made in basic laboratory studies, in animal models of otitis media, in better understanding the epidemiology of disease, and in clinical practice. Implications for Practice (1) Many viruses cause acute otitis media without bacterial coinfection, and such cases do not require antibiotic treatment. (2) When respiratory syncytial virus, metapneumovirus, and influenza virus peak in the community, practitioners can expect to see an increase in clinical otitis media cases. (3) Biomarkers that predict which children with upper respiratory tract infections will develop otitis media may be available in the future. (4) Compounds that target newly identified bacterial virulence determinants may be available as future treatment options for children with otitis media.

Abstract
BACKGROUND It is a known fact that bacterial or viral acute otitis media occurs more frequently in the winter months. Only a few older studies on seasonal differences in middle ear findings are available. These studies are based solely on tympanography, without correlation to intraoperative middle ear findings. This study addresses the question of whether seasonal differences can be found in the preoperative tympanogram and in the corresponding intraoperative findings in children with chronic middle ear problems. PATIENTS AND METHODS This retrospective study included patients who had undergone myringotomy with or without tympanostomy tube insertion at the Charité-Universitätsmedizin Berlin between January and December 2011. Corresponding to the catarrhal phases, winter months were defined as those from November to April; summer months from May to October. The preoperative tympanogram and the documented intraoperative middle ear finding were statistically analyzed for seasonal differences. RESULTS A total of 654 ears from 206 male and 127 female patients with mean age 3.7 ± 2.5 years were analyzed. In the majority of cases, a type B tympanogram was found (n = 376; 57.5%), whereas the middle ear was filled with air in 19.1% of cases. No significant seasonal differences were found for either the intraoperative middle ear findings or the preoperative tympanograms (p > 0.05). CONCLUSION For children with a typical history of chronic otitis media without effusion and chronic tube ventilation dysfunction, myringotomy with or without tympanostomy tube insertion is indicated independently of the season. The results indicate that a wait-and-see approach with hope of improvement during the summer months is not rational.

Abstract
Evidence-based medicine is an approach to medical treatment intended to optimize patient-oriented decision-making on the basis of empirically proven effectiveness. For this purpose, a classification system has been established to categorize studies - and hence therapy options - in respect of associated evidence according to defined criteria. The Eustachian tube connects the nasopharynx with the middle ear cavity. Its key function is to ensure middle ear ventilation. Compromised ventilation results in inflammatory middle ear disorders. Numerous evidence-based therapy options are available for the treatment of impaired middle ear ventilation and otitis media, the main therapeutic approach being antibiotic treatment. More recent procedures such as balloon dilation of the Eustachian tube have also shown initial success but must undergo further evaluation with regard to evidence. There is, as yet, no evidence for some of the other long-established procedures. Owing to the multitude of variables, the classification of evidence levels for various treatment approaches calls for highly diversified assessment. Numerous evidence-based studies are therefore necessary in order to evaluate the evidence pertaining to existing and future therapy solutions for impaired middle ear ventilation and otitis media. If this need is addressed, a wealth of implications can be expected for therapeutic approaches in the years to come.

Abstract
BACKGROUND Vaccines and antivirals against respiratory syncytial virus (RSV) are being developed, but there are scarce data on the full impact of RSV infection on outpatient children. METHODS We analyzed the burden of RSV illness in a prospective cohort study of children aged ≤13 years during 2 consecutive respiratory seasons in Turku, Finland (2231 child-seasons of follow-up). We examined the children and obtained nasal swabs for the detection of RSV during each respiratory illness. The parents filled out daily symptom diaries throughout the study. RESULTS Of 6001 medically attended respiratory infections, 302 (5%) were caused by RSV. Per 1000 children, the average annual RSV infection incidence rates among children aged <3, 3-6, and 7-13 years were 275, 117, and 46 cases, respectively. In children aged <3 years, acute otitis media developed in 58%, and 66% of children in this age group received antibiotics. The mean duration of RSV illness was longest (13.0 days) and the rate of parental work absenteeism was highest (136 days per 100 children with RSV illness) in children aged <3 years. CONCLUSIONS The burden of RSV is particularly great among outpatient children aged <3 years. Young children are an important target group for the development of RSV vaccines and antivirals.

Abstract
Background Human Parainfluenza Virus (hPIV) causes severe respiratory illness in infants and adults. Our study describes the association of hPIV1–4 with bronchiolitis, croup, and pneumonia using retrospective laboratory, administrative and public health data. Due to issues including the historic lack of hPIV4 in some commercial respiratory virus panels, the description of the impact of hPIV4 on croup, bronchiolitis, and pneumonia at population levels has often been limited. This study will use routine clinical laboratory data, and administrative data to provide a preliminary description of the impact of hPIV4 on these diseases in our population. Methods A three year cohort of patients positive for hPIV was linked with data from physician visits and hospital admissions to define cases and hospitalization status. International Classification of Disease (ICD-9) codes were used to determine if cases had croup, bronchiolitis, and pneumonia. We also looked at differences in hospitalization status, age and gender among hPIV1–4. All statistical analysis was done using SPSS (Version 19.0.0, IBM Corp© 2010) and Graphpad Prism V6 (GraphPad Software, Inc., 2012). Results Only hPIV1 and hPIV4 specimens had positivity rates greater than 5 % of all specimens sent for respiratory virus panel testing. hPIV1 exhibited a biennial pattern while the pattern for hPIV3 was less interpretable due to lower positivity rates. Circulation patterns for hPIV2 and hPIV4 were not assessed due to the low positivity rates of theses specimens. From 2010 to 2013, there were 2300 hPIV cases with hPIV3 (46 %) being the most common, followed by hPIV1 (27 %), hPIV4 (16 %) and hPIV2 (11 %). The median age was 2 years for all hPIV types. Males were slightly greater than females for hPIV1 and hPIV2, with an equal distribution for hPIV3 and slightly more females than males for hPIV4. hPIV1 and hPIV2 had the highest or proportion of croup while hPIV3 and hPIV4 had the highest proportion of pneumonia. Within hPIV4 cases, distributions of diseases were; pneumonia (21 %, 95 % CI 17.1–25.7), bronchiolitis (18 %, 95 % CI 14.3–22.5), croup (2 %, 95 % CI 0.8–3.9), mixed illness of any of pneumonia, bronchiolitis or croup (4 %, 95 % CI 2.5–7.0) or other respiratory diseases (54 %, 95 % CI 49.1–59.6). Conclusions We used laboratory and administrative data to undertake a descriptive analysis of the association of hPIV1–4 with croup, bronchiolitis and pneumonia. hPIV4 appears to be more associated more with bronchiolitis and pneumonia and less with croup in our population.

Abstract
Influenza is an important cause of morbidity and mortality among pregnant women and young infants, and influenza infection during pregnancy has also been associated with adverse obstetric and birth outcomes. There is substantial evidence - from randomized trials and observational studies - that maternal influenza immunization can protect pregnant women and their infants from influenza disease. In addition, there is compelling observational evidence that prevention of influenza in pregnant women can also protect against certain adverse pregnancy outcomes, including stillbirth and preterm birth. In this article we will review and evaluate the literature on both the burden of influenza disease in pregnant women and infants, as well as the multiple potential benefits of maternal influenza immunization for mother, fetus, and infant. We will also review key clinical aspects of maternal influenza immunization, as well as identify remaining knowledge gaps, and discuss avenues for future investigation.

Parental views on acute otitis media (AOM) and its therapy in children--results of an exploratory survey in German childcare facilities. BMC Pediatr 2015; 15:199.

Abstract
Background Acute otitis media (AOM) is one of the main reasons for medical consultation and antibiotic use during childhood. Although 80 % of AOM cases are self-limiting, antibiotic prescription is still high, either for physician- or for parent-related factors. This study aims to identify parental knowledge about, beliefs and attitudes towards, and experiences with AOM and its therapy and thus to gain insights into parents’ perspectives within the German health care system. Methods An exploratory survey was conducted among German-speaking parents of children aged 2 to 7 years who sent their children to a childcare facility. Childcare facilities were recruited by convenience sampling in different urban and rural sites in Germany, and all parents with children at those facilities were invited to participate. Data were evaluated using descriptive statistical analyses. Results One-hundred-thirty-eight parents participated. Of those, 75.4 % (n = 104) were AOM-experienced and 75.4 % (n = 104) had two or more children. Sixty-six percent generally agree that bacteria cause AOM. 20.2 % generally agree that viruses cause AOM. 30.5 % do not generally agree that viruses cause AOM. Eight percent generally agree that AOM resolves spontaneously, whereas 53.6 % do not generally agree. 92.5 % generally (45.7 %) and partly (42.8 %) agree that AOM needs antibiotic treatment. With respect to antibiotic effects, 56.6 % generally agree that antibiotics rapidly relieve earache. 60.1 % generally agree that antibiotics affect the gastrointestinal tract and 77.5 % generally agree that antibiotics possibly become ineffective after frequent use. About 40 % generally support and about 40 % generally reject a “wait-and-see” strategy for AOM treatment. Parental-reported experiences reveal that antibiotics are by far more often prescribed (70.2 %) than actively requested by parents (26.9 %). Conclusions Parental views on AOM, its therapy, and antibiotic effects reveal uncertainties especially with respect to causes, the natural course of the disease and antibiotic effects on AOM. These results indicate that more evidence-based information is needed if parents’ health literacy in the treatment of children with AOM is to be enhanced. The discrepancy between reported parental requests for antibiotics and reported actual prescriptions contradicts the hypothesis of high parental influence on antibiotic use in AOM.

Abstract
We recently identified a cohort of children with recurrent episodes of acute otitis media (AOM) who fail to generate protective antibody titres to otopathogens and several vaccine antigens. In this study we determined the antibody levels against DTaP vaccine antigens, diphtheria toxoid (DT), tetanus toxoid (TT) and acellular pertussis toxoid (PT) in sera from 15 stringently defined otitis-prone (sOP) children and 20 non-otitis-prone (NOP) children. We found significantly lower concentrations of immunoglobulin (Ig)G antibodies against vaccine antigens in the serum of sOP children compared to age-matched NOP children. To elucidate immunological cellular responses to the vaccines in these children, we investigated memory B cell responses to DTaP vaccination. We used fluorescently conjugated vaccine antigens to label antigen receptors on the surface of memory B cells and examined the frequency of antigen-specific CD19(+) CD27(+) memory B cells in the peripheral blood. sOP children showed a significantly lower percentage of antigen-specific CD19(+) CD27(+) memory B cells than NOP children. We also found a linear correlation between the frequencies of memory B cells and circulating IgG titres for DT, TT and PT proteins. To our knowledge, this is the first study to show significant differences in memory B cell responses to DTaP vaccine antigens and their correlation with the circulating antibodies in young children with recurrent AOM.

Abstract
BACKGROUND Bacteria and respiratory viruses are implicated in the pathogenesis of acute otitis media (AOM); however, data from low-middle income countries are sparse. We investigated the etiology of AOM in HIV-infected (HIV+), HIV-uninfected (HIV-) and HIV-exposed clinically asymptomatic for HIV-infection (HEU) South African children. METHODS Children ≥3 months to <5 years of age with AOM were enrolled between May 2009 and April 2010 (NCT01031082). Middle ear fluid samples were cultured for bacteria; antibacterial susceptibility was done and serotyping undertaken for Streptococcus pneumoniae and Haemophilus influenzae. Nasopharyngeal aspirates were analyzed for respiratory viruses using immunofluorescence assay and polymerase chain reaction. RESULTS Of 260 AOM episodes (HIV+:15; HIV-:182; HEU:63), bacteria were found in 54.6%, including Haemophilus influenzae (30.8%), 98.8% of which were nontypeable, and Streptococcus pneumoniae (20.4%), Staphylococcus aureus (15.8%), Moraxella catarrhalis (5.0%) and Streptococcus pyogenes (1.5%). Nonsusceptibility of Streptococcus pneumoniae to penicillin was 64.2%. Respiratory viruses were detected in 74.2% of cases. Human rhinovirus was most frequently detected (37.7%), followed by adenovirus (14.2%) and human bocavirus (11.5%) overall and irrespective of HIV status. Respiratory viruses were identified concurrently with S. pneumoniae, H. influenzae, M. catarrhalis (76.9-78.8%) and Staphylococcus aureus (63.4%) cultured from middle ear fluid, as well as in 72.0% of episodes negative for any bacteria. CONCLUSION The study suggests that respiratory viruses and pathogenic bacteria play an important role in the development of AOM in children. A similar spectrum of pathogens was observed independently of HIV status. Vaccines targeting both nontypeable Haemophilus influenzae and S. pneumoniae may have a broad impact on AOM in South Africa.

Abstract
BACKGROUND Increased upper respiratory infection (URI) among children at the beginning of school year is well known to parents and pediatricians. However, this phenomenon is not well documented or characterized. METHODS Computerized datasets from a large health maintenance organization in Israel were used to calculate the weekly rates of URI among children 3-14 years old for the years 2007-2012. In addition, nasopharyngeal swabs were collected in 2010-2012 from children with URI symptoms and controls during school opening time. Swabs were tested by real-time polymerase chain reaction for the presence of respiratory viruses. RESULTS Time-series analysis demonstrated a peak of URI in September each year. The peaks reached their height 2 weeks after school opening and returned to baseline within 4-7 weeks. The main 3 viruses detected both in URI patients and in healthy controls during the first weeks of school opening were rhinovirus, adenovirus and enterovirus. The detection rate of any respiratory virus, and of rhinovirus in particular, was significantly higher among cases than among controls (54% vs. 16%, P < 0.001 for any virus, and 35% vs. 6.0%, P < 0.01 for rhinovirus). When adjusting for age and sex cases had 5.8 times more viral detection when compared with controls. Upper respiratory symptoms were significantly more prevalent among the virus-positive cases when compared with negative ones. CONCLUSIONS Back-to-school illness consisting of URI has a distinct epidemiological pattern demonstrating a rapid rise peaking within 2 weeks of school opening and is associated predominantly with rhinovirus.

Abstract
PURPOSE OF REVIEW Acute otitis media occurs as a complication of viral upper respiratory tract infection. Bacterial otopathogens and respiratory viruses interact and play important roles in acute otitis media development. A better understanding of viral and bacterial interactions may lead to innovative ways to lessen the burden of this common childhood disease. RECENT FINDINGS There has been increasing evidence that acute otitis media occurs during upper respiratory infection, even in the absence of nasopharyngeal bacterial colonization. Among the types of viruses associated with acute otitis media, respiratory syncytial virus continues to be the most commonly detected. It is still unclear whether viral load plays an important role in acute otitis media development, but symptomatic upper respiratory tract infection (as opposed to asymptomatic viral infection) is crucial. Widespread use of bacterial and viral vaccines in young children, including pneumococcal conjugate and influenza vaccines, has led to the reduction in otitis media-related healthcare use between 2001 and 2011. There has been no new vaccine against respiratory viruses other than influenza. SUMMARY Progress has been made toward the reduction of the burden of acute otitis media in the last decade. Success in reducing acute otitis media incidence will rely mainly on prevention of nasopharyngeal otopathogen colonization, as well as reduction in the incidence of viral upper respiratory tract infection.

Abstract
The primary aim of this study was to test the hypothesis that the symptom of tinnitus demonstrates a seasonal pattern with worsening in the winter relative to the summer using Internet search engine query data. Normalized search volume for the term 'tinnitus' from January 2004 through December 2013 was retrieved from Google Trends. Seasonal effects were evaluated using cosinor regression models. Primary countries of interest were the United States and Australia. Secondary exploratory analyses were also performed using data from Germany, the United Kingdom, Canada, Sweden, and Switzerland. Significant seasonal effects for 'tinnitus' search queries were found in the United States and Australia (p < 0.00001 for both countries), with peaks in the winter and troughs in the summer. Secondary analyses demonstrated similarly significant seasonal effects for Germany (p < 0.00001), Canada (p < 0.00001), and Sweden (p = 0.0008), again with increased search volume in the winter relative to the summer. Our findings indicate that there are significant seasonal trends for Internet search queries for tinnitus, with a zenith in winter months. Further research is indicated to determine the biological mechanisms underlying these findings, as they may provide insights into the pathophysiology of this common and debilitating medical symptom.

Differential impact of respiratory syncytial virus and parainfluenza virus on the frequency of acute otitis media is explained by lower adaptive and innate immune responses in otitis-prone children.

Abstract
BACKGROUND Acute otitis media (AOM) is a leading cause of bacterial pediatric infections associated with viral upper respiratory infections (URIs). We examined the differential impact of respiratory syncytial virus (RSV) and parainfluenza virus URIs on the frequency of AOM caused by Streptococcus pneumoniae (Spn) and nontypeable Haemophilus influenzae (NTHi) in stringently defined otitis-prone (sOP) and non-otitis-prone (NOP) children as a potential mechanism to explain increased susceptibility to AOM. METHODS Peripheral blood and nasal washes were obtained from sOP and NOP children (n = 309). Colonization events and antiviral responses consisting of total specific immunoglobulin G (IgG) responses, neutralizing antibody responses, and T-cell responses were determined. Isolated neutrophils were infected with varying multiplicities of infection of both viruses, and opsonophagocytosis potential was measured. RESULTS A significant increase was found in frequency of AOM events caused by Spn and NTHi, with a concurrent RSV infection in sOP children. These results correlated with diminished total RSV-specific IgG, higher viral nasal burdens, and lower IgG neutralizing capacity. The sOP children had diminished T-cell responses to RSV that correlated with lower Toll-like receptor 3/7 transcript and decreased expression of HLA-DR on antigen-presenting cells. RSV interfered with the Spn phagocytic capacity of neutrophils in a dose-dependent manner. Parainfluenza virus infections did not differentially affect AOM events in sOP and NOP children. CONCLUSIONS Lower innate and adaptive immune responses to RSV in sOP children may slow the kinetics of viral clearance from the nasopharynx and allow for viral interference with antibacterial immune responses, thus contributing to increased frequency of AOMs.

Abstract
The placement of myringotomy tubes remains an effective treatment of recurrent acute otitis media and chronic otitis media with effusion. Infants and young children are prone to these entities because of their immature anatomy and immunology. Several host, pathogenic, and environmental factors contribute to the development of these conditions. The identification and modification of some these factors can preclude the need for intervention. The procedure continues to be one of the most common outpatient pediatric procedures. Close vigilance and identification of potential complications is of utmost importance in the ongoing management of the child with middle ear disease.
