OBJECTIVES
There is limited but consistent evidence that suggests prenatal factors, including maternal stress, may contribute to susceptibility for otitis media. We aimed to determine the effect of multiple life stress events during pregnancy on risk of acute and recurrent otitis media in offspring at three and five years of age.
METHODS
Exposure data on stressful life events were collected from pregnant women in a longitudinal prospective pregnancy cohort study, at 18 and 34 weeks' gestation. We used longitudinal regression models stratified by offspring sex to examine associations between the number, type and timing of maternal prenatal stress events and the likelihood of any OM in addition to recurrent OM infection at age three and five years, adjusting for pre-specified prenatal sociodemographic and environmental confounders.
RESULTS
Each additional stressful life event in pregnancy was associated with increased risk of any OM at both ages (3 years: OR = 1.07, 95%CI = 1.02, 1.12; 5 years: OR = 1.07, 95%CI = 1.02, 1.12), with larger effect sizes for recurrent otitis media (3 years: OR = 1.11, 95%CI = 1.05, 1.17; 5 years: OR = 1.09, 95%CI = 1.04, 1.14). Risk of offspring otitis media did not differ with timing of stress nor by offspring sex. Specific types of stress (pregnancy and relationship problems, issues with other children) were each associated with increased risk of recurrent OM at age three and five years.
CONCLUSIONS
We observed a dose-response relationship between maternal stressful life events in pregnancy and the risk for offspring otitis media in the preschool years, most marked for recurrent otitis media.

In infants and children, bacterial meningitis caused by anaerobic bacteria is rare. However, a serious infection with the anaerobe can occur in previously healthy children with a peak incidence in preschool children and in adolescents. As the clinical presentation can be very similar to meningitis caused by aerobic bacteria, one should consider as the causative agent when preceded by or associated with otitis media with purulent otorrhea or mastoiditis, in combination with minimal or no improvement on empiric antibiotic treatment. As this pathogen can be difficult to culture, anaerobic cultures should be obtained. Prompt treatment with a third-generation cephalosporin and metronidazole should be initiated once suspected or confirmed. Surgical source control is often necessary, but even with adequate and prompt treatment, the morbidity and mortality in children with a meningitis remains high. In this report, we describe a case of meningitis in a previously healthy child and review the available literature.

Olfactory neuroblastoma (ONB) is an uncommon malignant tumor and is usually treated by a multidisciplinary approach includes surgery, radiotherapy, and chemotherapy. A 62 years-old male had a tumor in the nasal cavity and diagnosed as ONB with Kadish A stage. Anterior skull base surgery was performed as radical treatment. Since the surgical margin was negative, no postoperative radiotherapy was administered. 14 years after the surgery, bilateral otitis media with effusion (OME) was occurred, we found the recurrence tumor at bilateral retropharyngeal lymph node (RPLN) which surrounded the internal carotid arteries. Since these were unresectable, we planned chemoradiotherapy which was 70Gy of intensity modulated radiotherapy combined with two courses of carboplatin and etoposide. The tumor volume was reduced and bilateral OME were improved. He has been alive for 3 years after salvage treatment. Although ONB has a relatively good prognosis, it is known to often cause cervical lymph node metastasis. Grades III and IV of Hyams classification are considered high risk. This case, initial tumor was limited in the nasal cavity and its clinical classification was early stage, but Hyams classification was grade III. In reference to this case, considering that RPLN metastasis are difficult to radically resect at the salvage surgery, including this area in postoperative radiotherapy was considered an option.

Clinical Otolaryngology : Official... Jun 2024This study compares hearing outcomes of two prosthesis materials, bone and titanium, used in ossiculoplasty.
OBJECTIVES
This study compares hearing outcomes of two prosthesis materials, bone and titanium, used in ossiculoplasty.
DESIGN
This retrospective nationwide registry-based study uses data systematically collected by the Swedish Quality Registry for Ear Surgery (SwedEar).
SETTING
The data were obtained from clinics in Sweden that perform ossiculoplasty.
PARTICIPANTS
Patients who underwent ossiculoplasty using either bone or titanium prostheses were registered in SwedEar between 2013 and 2019.
MAIN OUTCOME MEASURES
Hearing outcome expressed as air-bone gap (ABG) gain.
RESULTS
The study found no differences between bone and titanium for ABG or air conduction (AC) for either partial ossicular replacement prostheses (PORP) or total ossicular replacement prostheses (TORP). In a comparison between PORP and TORP for ABG and AC outcomes, regardless of the material used, PORP showed a small advantage, with an additional improvement of 3.3 dB (95% CI [confidence interval], 0.1-4.4) in ABG and 2.2 dB (95% CI, 1.7-4.8) in AC. In secondary surgery using TORP, titanium produced slightly better results for high-frequency pure tone average. The success rate, a postoperative ABG ≤20 dB, was achieved in 62% of the operations for the whole group.
CONCLUSION
Both bone and titanium used to reconstruct the ossicular chain produce similar hearing outcomes for both PORP and TORP procedures. However, titanium may be a preferable option for secondary surgeries involving TORP. The success rate, a postoperative ABG ≤20 dB, is consistent with other studies, but there is room for improvement in patient selection criteria and surgical techniques.

Palatine and pharyngeal tonsil hypertrophy may lead to dysfunction of the auditory tube due to a propensity for infection, potentially giving rise to otitis media. This is a quantitative and longitudinal study, developed from 2019 to 2021, at the State University of Campinas (UNICAMP). The studied sample comprised 15 participants aged 5 to 12 years (mean 7.9 years), 12 male and 3 female, arranged into two groups: children diagnosed with pharyngeal and/or palatine tonsil hypertrophy who were candidates for surgery (G1), and children who were later evaluated after surgery (G2). As part of the test, an otoscopy and measurements of logoaudiometry, pure-tone threshold audiometry, wideband tympanometry (ambient and peak pressure), and otoacoustic emissions (TEOAEs and DPOAEs, both at ambient and peak pressure) were all performed. There were statistically significant differences between phases in pure-tone audiometry, in terms of 226 Hz tympanometry, wideband tympanometry in peak pressure conditions, in the amplitude measurement TEOAEs in both pressure conditions, in DPOAEs in ambient pressure conditions, and in the signal/noise measurement in both pressures in DPOAEs. Overall, it was found that hearing tests were different for subjects with palatine and pharyngeal tonsil hypertrophy compared to the post-surgical group.

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

A 2-year-old Norwegian Forest cat was presented for evaluation of bilateral purulent nasal discharge and stertorous breathing. A computed tomography (CT) scan of the head revealed an intranasal mass of the left nasal cavity extending behind the tube openings and completely obstructing the nasopharynx. Rhinoscopy confirmed a pinkish, shiny mass. CT scan showed both compartments of the right middle ear filled with abnormal soft tissue attenuating material. There was no change in the bony outline of the middle ear. In the endoscopic examination, after endoscopically assisted tympanocentesis, this material in the accessible dorsolateral compartment proved to be classic polypous tissue in addition to highly viscous glue-like secretions. A secondary otitis media due to a drainage disorder was suspected.Using an endoscopic-interventional approach through the nostril, the nasopharyngeal mass was removed for histopathological examination, in order to restore the nasal airway, and to allow tube drainage. In contrast to cats with classical malignant nasal cavity masses, the cat showed several attachment points of the mass and multiple undulating elevations bilaterally in the nasopharyngeal mucosa.Cytological and histopathological examination identified the mass as a fungal granuloma in the context of a cryptococcus infection only rarely observed in Germany. Molecular genetic analysis confirmed an infection with var. .A single intranasal and nasopharyngeal endoscopic debridement resulted in a significant improvement of the clinical signs and a complete healing of the right middle ear (including the tympanic membrane) within 14 days, but not in a complete cure of the disease. The cat was therefore treated with oral itraconazole solution for several weeks.The case report shows that nasal cryptococcosis can also affect cats in Germany. Rhinoscopy reveals a nasopharyngeal mass with multiple attachment points, which is unusual for a neoplasia. In addition to the recommended removal of the mass, oral administration of systemic antimycotics is strongly advised.

Review
Over the past 2 decades, the increasing availability of computed tomography (CT) and magnetic resonance imaging (MRI) as well as the growing professional expertise have significantly improved the diagnostics of middle and inner ear diseases in dogs and cats. In answering some of the diagnostic questions, CT and MRT demonstrate equivalent performance. For most questions, however, there are differences in the diagnostic performance due to the physical imaging properties of the 2 modalities.CT is more sensitive in demonstrating involvement of the bulla wall and is more effective for detecting abnormal content within the tympanic bulla. In addition, with CT it is often easier to guide tissue samplings. On the other hand, structural changes of the soft tissues of the skull, head, meninges, brain, and nerves are not or only insufficiently detectable on CT images. MRI is clearly superior here. Therefore, MRI is essential for the characterization of materials inside the bulla cavity and for demonstrating the extent of any central spread of otitis media (OM).In this image essay, CT and MRI features of OM and resulting secondary lesions described in the literature are analyzed and summarized. Own image examples are used for illustration. Information on the etiology, pathogenesis, pathomorphology, and clinical signs important for understanding these changes are presented in concise descriptions.

OBJECTIVE
To describe secondary secretory otitis media (SSOM) due to obstruction of the nasopharyngeal opening of the auditory tube in cats and dogs and to characterize the effusion by macroscopic description, microscopic cytology and bacteriological analysis.
MATERIAL AND METHODS
Three cats and 2 dogs with middle ear effusion and obstruction of the nasopharyngeal opening of the auditory tube detected on CT scans received myringotomy followed by macroscopic description, microscopic cytology and bacteriological analysis of the fluid obtained.
RESULTS
All animals had serous to mucoid middle ear effusions and, in 2 cases, large numbers of inflammatory cells and secondary infection. Causes of auditory tube dysfunction ranged from iatrogenic stents (2) to neoplasia (3). In the non-neoplastic cases, effusion resolved in all cases after removal of the underlying cause.
CONCLUSIONS AND CLINICAL RELEVANCE
Obstruction of the nasopharyngeal opening of the auditory tube leads to accumulation of fluid within the middle ear in cats and dogs. If the cause of obstruction can be removed, fluid accumulation resolves. Fluid characteristics are comparable to middle ear effusions in pugs and French bulldogs. It is important to always examine the nasopharynx in cases of middle ear effusion to rule out SSOM.

Introduction The Eustachian tube regulates middle ear functions such as ventilation and pressure normalization. Eustachian tube dysfunction (ETD) is defined as the failure of the Eustachian tube to maintain one or more of its functions. It is a common condition that is associated with other middle ear disorders such as cholesteatoma, tympanic membrane atelectasis, and otitis media with effusion (OME). This study aims to assess ETD prevalence and risk factors in the Qassim region. Methodology This cross-sectional study was conducted in the Qassim region of Saudi Arabia during the period from September 20 to October 10, 2023. Data were gathered via a validated, self-administered electronic questionnaire that encompasses socio-demographic information, the prevalence of ETD, and the prevalence of its various symptoms, as assessed by the Eustachian Tube Dysfunction Questionnaire (ETDQ-7). Results Our study in Qassim, Saudi Arabia, with 467 participants reveals a high prevalence of ETD at 12.2%. The 18-25 age group dominates (50.1%), with a majority of females (66.2%). Symptom analysis using the ETDQ-7 questionnaire shows varied prevalence, with severe pain (7%) and muffled hearing (29.8%) notable. Logistic regression identifies significant predictors, including hearing loss history (odds ratio = 28.2) and smoking (odds ratio = 3.70). Specific symptoms, such as feeling blocked or underwater, significantly correlate with more severe ETD symptoms (odds ratio = 1.73). Conclusion Our study highlights a notable prevalence of ETD. Significant predictors, including hearing loss history and smoking, were identified. Specific symptoms, such as feeling blocked or underwater, were associated with more severe ETD symptoms.
