[Ab] Resumo:To summarize the clinical characteristics and therapeutic experiences of the middle ear teratoma in infants. Three cases of middle ear teratoma, from 2012-2015 in Beijing Friendship Hospital were analyzed. The three cases all developed slowly and presented unilateral otorrhea and hearing loss. Otoscopy showed the granulation tissue in the external ear canal. Audiological changes varied according to the degree of severity. Imaging features showed the pocket-like occupancy lesions in the Eustachian tube area. The temporal bone CT showed mass with soft tissue density usually involved in the mastoid and tympanic cavity. MRI showed mixed signal intense on both T1 and T2 weighted imaging. All the three cases received neoplasm resection of the middle ear. Only one case received tympanoplasty surgery at the same time. And all the pathology results displayed mature teratoma. The follow-up time was 17 to 54 months. MRI showed complete removal of the tumor. Teratoma are rare in the head and neck neoplasm. When the infants suffer from the unilateral otorrhea, hearing loss, and granulation tissue formed in the external ear canal, it should be vigilant for teratoma. The differential diagnosis is middle ear cholesteatoma, congenital first branchial cyst or fistula, and middle ear carcinoma. Temporal bone CT combined with MRI could improve the accuracy of diagnosis. It should be totally resection as soon as possible if there is no contraindication. Postoperative follow-up and imaging examination are necessary to eliminate tumor recurrence.

[Ab] Resumo:PURPOSE: We aimed to evaluate the diagnostic accuracy of turbo spin-echo diffusion-weighted imaging (TSE-DWI) at 3 T, for cholesteatoma (CS) diagnosis, using qualitative and quantitative methods with numerical assessment of signal intensity (SI), signal intensity ratios (SIR), and apparent diffusion coefficient (ADC) values. METHODS: In this retrospective study, two blinded observers independently evaluated the preoperative TSE-DWI images of 57 patients who were imaged with a presumed diagnosis of CS. Qualitative assessment with respect to the SI of the adjacent cortex and quantitative measurements of SI, SIR, and ADC values were performed. RESULTS: Surgery with histopathologic examination revealed 30 CS patients and 27 patients with non-cholesteatoma (NCS) lesions including chronic inflammation and cholesterol granuloma. On TSE-DWI, 96.7% of the CS lesions and none of the NCS lesions appeared hyperintense compared with the cortex. The mean SI and SIR indices of the CS group were significantly higher and the mean ADC values significantly lower compared with those of the NCS group (P < 0.001). Using specific cutoff values for SI (92.5) and SIR (0.9), CS could be diagnosed with 100% sensitivity and specificity. The use of quantitative imaging further increased the sensitivity of the TSE-DWI technique. CONCLUSION: The quantitative indices of SI, SIR, and ADC of TSE-DWI appear to be highly accurate parameters that can be used to confirm the diagnosis of CS.

[Ab] Resumo:The aim of the present study was to investigate the influence of different types of tasks performed with or without an electronic device (tablet) on pre-sleep alertness, subsequent sleep quality and next-day athletic performance. Eight highly trained netball players attended a sleep laboratory for pre-sleep testing, polysomnographic sleep monitoring and next-day physical performance testing on 5 separate occasions (1 familiarisation and 4 experimental sessions). For 2 h prior to bedtime, athletes completed cognitively stimulating tasks (puzzles) or passive tasks (reading) with or without a tablet. Sleepiness tended to be greater after reading compared to completing puzzles without a tablet (d = 0.80), but not with a tablet. Melatonin concentration increased more so after reading compared to completing puzzles on a tablet (P = 0.02). There were no significant differences in sleep quality or quantity or next-day athletic performance between any of the conditions. These data suggest that using a tablet for 2 h prior to sleep does not negatively affect subsequent sleep or next-day performance in athletes.

[Ti] Título:Recurrent otorrhea in chronic suppurative otitis media: is biofilm the missing link?

[Ab] Resumo:Dispersal of bacteria from a biofilm in the middle ear, serving as a bacterial reservoir, could explain the recurrent and chronic nature of chronic suppurative otitis media (CSOM). The objective of this study is to investigate if the same strains of bacteria could be detected in repeated episodes of otorrhea in CSOM. In a prospective case series at a primary healthcare clinic in Nuuk, Greenland, patients with more than 14 days of otorrhea were included consecutively. Samples for culturing and biofilm analysis were taken at enrollment and at any subsequent episode with otorrhea. Participants were treated with daily saline irrigation and Ciprofloxacin eardrops for 7-14 days. Biofilm was identified in otorrhea in 81% (17/21) of participants at enrollment. Multispecies infections dominated with Non-typeable Haemophilus Influenzae (NTHI), Staphyloccocus aureus, and anaerobes being the most frequent pathogens. After the initial treatment, 19 (90%) had dry ears. Median observation period was 140 days (range 14-280) where 13 participants had one or more recurrences. Median time to first recurrence was 60 days (range 14-197). Among the 13 with recurrence, three individuals had the same genotype of bacteria at a subsequent episode. Another two had the same phenotype (NTHI). The remaining eight had new multispecies infections. We confirmed a high rate of biofilm in CSOM. However, the clinical implication might be of minor importance when treating with irrigation and antibiotic eardrops, as recurrent episodes of otorrhea were dominated by new pathogens in each episode.

[Ab] Resumo:(SA) and (PA) are known to cause biofilm-related infections. MRSA and PA have been frequently isolated from chronically infected wounds, cystic fibrosis, chronic suppurative otitis media (CSOM), and from indwelling medical devices, and these bacteria co-exist; however, their interaction with each-other or with the host is not well known. In this study, we investigated MRSA and PA multi-species biofilm communities and their interaction with the host during colonization using an OM rat-model. biofilm formation and colonization were studied using CV-microtiter plate assay and OM rat-model respectively. The biofilms were viewed under scanning electron microscope and bacteria were enumerated using cfu counts. The differential gene expressions of rat mucosa colonized with single or multi-species of MRSA or PA were studied using RNA-sequencing of total transcriptome. In multi-species biofilms PA partially inhibited SA growth. However, no significant inhibition of MRSA was detected during colonization of multi-species in rat bullae. A total of 1,797 genes were significantly ( < 0.05) differentially expressed in MRSA or PA or MRSA + PA colonized rat middle ear mucosa with respect to the control. The poly-microbial colonization of MRSA and PA induced the differential expression of a significant number of genes that are involved in immune response, inflammation, signaling, development, and defense; these were not expressed with single species colonization by either MRSA or PA. Genes involved in defense, immune response, inflammatory response, and developmental process were exclusively up-regulated, and genes that are involved in nervous system signaling, development and transmission, regulation of cell growth and development, anatomical and system development, and cell differentiation were down-regulated after multi-species inoculation. These results indicate that poly-microbial colonization induces a host response that is different from that induced by single species infection.

[Ti] Título:Role of antibodies and IL17-mediated immunity in protection against pneumococcal otitis media.

[Ab] Resumo:Widespread vaccination against Streptococcus pneumoniae (the pneumococcus) has significantly reduced pneumococcal disease caused by vaccine serotypes. Despite vaccination, overall pneumococcal colonization rates in children have not reduced and otitis media (OM) by non-vaccine serotypes remains one of the most common childhood infections. Pneumococcal surface protein A (PspA) has been shown to be a promising protein antigen to induce broad protection against pneumococcal colonization. However, its ability to protect against OM remains unclear. Using our previously established mouse model of influenza-virus induced pneumococcal OM, we here show that intranasal vaccination of mice with PspA together with the mucosal adjuvant CTB results in a decrease in pneumococcal load in the middle ears. This decrease correlated with the induction of PspA-specific IgA, a balanced IgG1:IgG2a antibody response and the induction of a mucosal Th17 response. Our data suggests that the IL-17 response to PspA is more important for protection against OM, whilst the presence of antibodies may be less important, as determined in mice deficient in IL-17 signaling or antibody production. Together, these results suggest that mucosal vaccination with PspA may not only protect against colonization, but also against the development of virus-induced pneumococcal OM.

[Ti] Título:Influence of repetitive diving in freshwater on pressure equalization and Eustachian tube function in recreational scuba divers.

[Ab] Resumo:INTRODUCTION: We investigated the effect of repetitive pressure exposure during freshwater dives on Eustachian tube function and the middle ear, assessed by the Eustachian tube function test (ETFT). METHODS: This prospective observational cohort study included 23 divers over three consecutive days of diving in freshwater lakes in Nordhausen, Germany. Participants underwent otoscopy and ETFT before the first dive, between each dive and after the last dive. ETFT included regular tympanometry (R-tymp), tympanometry after Valsalva (V-tymp) and after swallowing (S-tymp). The peak pressure difference between the R-tymp and the V-tymp (R-V ) defined effectiveness of pressure equalization after Valsalva manoeuvres. We evaluated the change in compliance and peak pressure and correlated the results to the otoscopic findings and diving experience. RESULTS: Twenty-three divers performed 144 dives. Middle ear barotrauma was assessed using the Edmonds modification of the TEED scoring system. In the ETFT, the R-tymp peak pressure displayed a negative shift from day one to three (P = 0.001) and differed significantly between the experience groups (P = 0.01). R-V did not change significantly on any of the three days of diving (all P > 0.05). Participants without MEBt showed significantly lower R-tymp values than did those with barotrauma (P = 0.019). CONCLUSION: Repetitive pressure exposure during three consecutive days of freshwater diving led to a negative shift of the peak pressure in the middle ear. Less experienced divers showed significantly higher middle ear peak pressure and higher pressure differences after equalization manoeuvres. Higher middle ear peak pressure was also associated with a higher prevalence of barotrauma.

[Ab] Resumo:INTRODUCTION: We investigated in a prospective, observational trial the feasibility of using the Eustachian tube function test (ETFT) to measure the effect of repetitive pressure exposure during open seawater dives on Eustachian tube function. METHODS: The study included 28 adult divers during six consecutive days of diving in the Red Sea. Participants underwent otoscopy and ETFT before the first dive, between each dive and after the last dive. ETFT included regular tympanometry (R-tymp), tympanometry after Valsalva (V-tymp) and after swallowing (S-tymp). The R-tymp was obtained as 'baseline' peak pressure. After a Valsalva, the peak pressure should shift (positively), revealing a positive shift of the tympanic membrane. This pressure shift is defined here as R-V . The changes in compliance and peak pressure were recorded and correlated with otoscopic findings and diving experience. Middle ear barotrauma was scored using the Edmonds modified TEED scale. RESULTS: The 28 participants performed 437 dives. Positive shift of pressure in the middle ear was evident with significant changes from day one to day three (P < 0.0001). Divers with barotrauma showed significantly lower values of R-tymp peak pressure and significantly higher negative R-V , compared to divers with normal otoscopic findings (P < 0.05). Diving experience significantly correlated with R-tymp peak pressure and prevalence of middle ear barotrauma. CONCLUSION: Significant changes in middle ear pressure and pressure equalization from repeated pressure exposure in saltwater were seen using ETFT. Repetitive, multi-day diving led to significantly decreased compliance and increased R-tymp peak pressure (overpressure) in the middle ear. Most profound changes were observed in less and intermediate experienced divers.

[Ab] Resumo:OBJECTIVE: To describe a transoral approach for tympanic bulla osteotomy in the dog. STUDY DESIGN: Anatomic cadaveric study. SAMPLE POPULATION: Fifteen canine cadavers (n = 29 tympanic bullae), including mesaticephalic, dolichocephalic, and brachycephalic breeds. MATERIALS AND METHODS: The oral surface of the tympanic bulla was identified during an anatomical study (3 canine cadavers) and the ventral approach to the tympanic bulla was described (3 canine cadavers). The safety of the technique was assessed (9 canine cadavers, n = 17 bullae) during further anatomical dissections, where a complete approach and drilling of the tympanic bulla were performed. RESULTS: In all cases, tympanic bulla osteotomy was performed without damaging the inner ear, the epitympanic recess contents, and the neurovascular structures. The oral approach to the tympanic bulla was easier in mesaticephalic and dolichocephalic dogs than in brachycephalic breeds. CONCLUSION: This study defines anatomical landmarks for transoral bulla osteotomy, without a high risk of damage to neurovascular and anatomical structures within and/or surrounding the tympanic cavity. This minimally invasive approach to the tympanic bulla is performed via a natural opening, and does not require simultaneous access through the ear canal. In vivo evaluation of this technique is required to verify its safety in clinical cases prior to large scale application.

[Ab] Resumo:INTRODUCTION: Tympanostomy tube placement is the most common surgical procedure performed in children. Medial migration of a tympanostomy tube is a rare occurrence where the tube migrates into the middle ear cavity as opposed to its normal extrusion into the external auditory canal. Whether medialized tympanostomy tubes should be surgically removed in asymptomatic patients is controversial. The objective of this study was to determine experience and management approach of medialized tympanostomy tubes among pediatric otolaryngologists. METHODS: A 12-question cross-section survey was designed and distributed to the American Society of Pediatric Otolaryngology (ASPO) members. The survey study was granted McGill University institutional review board and ASPO research committee approval. The survey data were filtered and cross-tabulated. Descriptive statistics were generated. RESULTS: 128 pediatric otolaryngologists completed the 12-question survey. The majority of respondents had experienced at least one case of medialized tympanostomy tube (90.6%). The majority of patients (82.0%) were asymptomatic. 74 out of 128 respondents (57.8%) indicated that they would not remove a medialized tube in an asymptomatic patient. However, 7.0% of those respondents clarified that they would proceed to surgical removal if the patient were undergoing general anesthesia for another surgery. 30.5% of respondents indicated that they would surgically remove the tube even if the patient were asymptomatic. 6.3% of respondents indicated that opted management in children would be based on a shared decision with parents. Most respondents (80.5%) did not experience complications with surgical removal nor with elected observation. CONCLUSION: There is no consensus among pediatric otolaryngologists regarding the necessity of surgically removing a medialized tympanostomy tube in asymptomatic patients. The survey suggests that both options are acceptable. If observation is chosen, it is important that parents are well informed of the potential long-term sequelae of a medialized tube and advised to consult if symptoms occur.
