Impact of COVID-19 pandemic on the incidence of otitis media with effusion in adults and children: a multicenter study.

PURPOSE: To compare and analyze the incidence of otitis media with effusion (OME), before and during the COVID-19-related pandemic period, to evaluate the effects of the social changes (lockdown, continuous use of facial masks, social distancing, reduction of social activities) in the OME incidence in children and adults. METHODS: The number of diagnosed OME in e five referral centers, between 1 March 2018 and 1 March 2021, has been reviewed and collected. To estimate the reduction of OME incidence in children and adults during the COVID-19 pandemic period the OME incidence in three period of time were evaluated and compared: group 1-patients with OME diagnosis achieved between 1/03/2018 and 01/03/2019 (not pandemic period). Group 2-patients with OME diagnosis achieved between 1/03/2019 and 1/03/2020 (not pandemic period). Group 3-patients with OME diagnosis achieved between 1/03/2020 and 1/03/2021 (COVID-19 pandemic period). RESULTS: In the non-pandemic periods (group 1 and 2), the incidence of OME in the five referral centers considered was similar, with 482 and 555 diagnosed cases, respectively. In contrast, the OME incidence in the same centers, during the pandemic period (group 3) was clearly reduced with a lower total number of 177 cases of OME estimated. Percentage variation in OME incidence between the first non-pandemic year considered (group 1) and the pandemic period (group 3) was-63, 3%, with an absolute value decrease value of-305 cases. Similarly, comparing the second non-pandemic year (group 2) and the pandemic year (group 3) the percentage variation of OME incidence was-68, 1% with an absolute value of-305 cases decreased. CONCLUSIONS: Our findings showed a lower incidence of OME during the pandemic period compared with 2 previous non pandemic years. The drastic restrictive anti-contagion measures taken by the Italian government to contain the spread of COVID-19 could have had a positive impact on the lower OME incidence during the last pandemic year.

Radiological Parameters Review for Choanal Atresia.

(1) Background: The study aims to identify which imaging parameters are necessary for a new correct surgical approach in the study of choanal atresia, and which anatomical findings are essential for correct planning of endoscopic treatment in choanal atresia. (2) Methods: In this retrospective study, 19 patients with choanal atresia had high-resolution multiplanar imaging (14 cases aged ≤1 year and 5 cases aged 1 to 3 years) and 35 patients in the control group similarly distributed by age. Fourteen variables, the most relevant from a surgical point of view, were selected and measured. A comparison was made between the averages of the study group and the different control groups, either directly observed or selected from the literature, using Pearson's correlation. (3) Results: In 14 out of 26 cases, the differences were statistically significant. There was a correlation between the structures assessed, such as choanal height, rostrum height, and age. (4) Conclusions: Thanks to volumetric reformatting, this work identified and provided the clinician with useful information that helped choose the correct surgical approach. Furthermore, it focused on which imaging parameters are necessary to improve the planning of the surgical correction of choanal atresia.

Eustachian Tube Dysfunction in Children With Adenoid Hypertrophy: The Role of Adenoidectomy for Improving Ear Ventilation.

INTRODUCTION: To our knowledge, few papers have addressed preoperative evaluation of the impact of adenoid hypertrophy (AH) on the pathogenesis of eustachian tube dysfunction (ETD) in children with otitis media with effusion (OME). AIM: The aim of this study was 2-fold: first, to evaluate ETD using tubomanometry and Eustachian Tube Score 7 (ETS-7), in a group of children having AH; second, to assess the clinical impact of adenoidectomy on the ETD of these patients. METHODS: Fifty patients, aged 4 to 15 years, underwent adenoidectomy based on various parameters: size of the adenoids causing canal obstruction (grades 1-4), the presence of OME, and recurrent episodes of rhinosinusitis. The function of the eustachian tube was evaluated using ETS-7 before and after surgical treatment. The patients were followed up for 6 months. RESULTS: Forty children presented ETD. Of these, 36 had a grade 4 AH. The preoperative mean value for ETS-7 was 6.62. The mean postoperative ETS-7 score showed a value of 9.60 with a statistical difference compared to the preoperative value (P = .0015). CONCLUSIONS: Adenoid hypertrophy has a high impact on the frequency of ETD. In the patients observed in the present study, the ETS-7 score appeared to be a valid tool for assessing ETD both preoperatively and postoperatively. Adenoidectomy seemed to be effective in improving ETD as well as middle ear ventilation.

Solitary juvenile xanthogranuloma of the hypopharynx. Clinico-pathologic study in a child with ß-Thalassemia Major and Cutaneous Mastocytosis.

Juvenile Xanthogranuloma (JXG), the most common pediatric non-Langerhans cell histiocytosis, may rarely occur in association with Neurofibromatosis (types 1 and 2), Juvenile Myelomonocytic Leukemia and Cutaneous Mastocytosis (CM) and, morphologically, mimics Erdheim-Chester Disease tissue lesions and ALK-positive histiocytosis. We describe a 4-year-old girl with Beta-Thalassemia Major who developed an hypopharyngeal BRAFV600E- and ALK-negative JXG and CM. JXG has been rarely reported in the aerodigestive tract and in association with CM. In this molecular era, knowledge of genetic heterogeneity of JXG and clinical scenarios in which it may develop is essential for the appropriate diagnosis and treatment of each individual patient.

Local allergic rhinitis in children: Novel diagnostic features and potential biomarkers.

BACKGROUND: Local allergic rhinitis (LAR) is a phenotype of rhinitis that has been poorly studied in children. It is characterized by the same symptoms of allergic rhinitis but with the absence of markers of systemic atopy. OBJECTIVE: To identify children affected by LAR and to analyze the pathogenesis of this disease. We chose to focus our attention on interleukin (IL) and thymic stromal lymphopoietin (TSLP). METHODS: We enrolled 20 children affected by nonallergic rhinitis (negative skin-prick test results and serum specific immunoglobulin E [sIgE] values). Each patient underwent a nasal allergen provocation test (NAPT) with dust mite and grass pollen. Before and after NAPT, nasal lavage was performed to detect sIgE, IL-5, and TSLP; anterior active rhinomanometry was used to evaluate changes in nasal obstruction. RESULTS: Two patients were positive to a nonspecific NAPT and, thus, were excluded from the study. Of the remaining 18 children, 12 (66.7%) had positive results to at least one NAPT. Among these 12 patients, nasal sIgE levels for Dermatophagoides pteronyssinus, Dermatophagoides farinae, and Lolium perenne increased significantly after NAPT (D. pteronyssinus, p < 0.005; D. farinae, p < 0.05; L. perenne, p < 0.05). Nasal IL-5 levels showed a significant increase after NAPT (p ≤ 0.006), and this increase was significantly higher in children who had positive NAPT results than in those patients with negative NAPT results (p ≤ 0.03). Among the 12 children who had a positive NAPT result, nasal TSLP was detected in 4 patients (33.3%) and its levels showed a relevant increase after NAPT, even though the difference did not reach statistical significance (p ≤ 0.061). CONCLUSION: Observed results raise the importance of better refining the diagnostic protocol for LAR in children. Nasal TSLP and IL-5 levels offer new insights concerning localized allergic inflammation, although the role of nasal sIgE has still to be clarified.

Cephalometric pattern and nasal patency in children with primary snoring: the evidence of a direct correlation.

INTRODUCTION: Sleep disordered breathing (SDB) might affect craniofacial growth and children with obstructive sleep apnea syndrome present an increase in total and lower anterior heights of the face and a more anterior and inferior position of the hyoid bone when compared to nasal breathers. OBJECTIVE: To investigate the correlation between rhinomanometric and cephalometric parameters in children with primary snoring (PS), without apnea or gas exchange abnormalities. MATERIALS AND METHODS: Thirty children with habitual snoring (16 females and 14 males) aged 4-8 years (mean age 6.85±1.51 years) were selected by a SDB validate questionnaire. All subjects underwent lateral cephalometric, panoramic radiographies. RESULTS: In our sample 10 children (33%) had snoring 3 nights/week, 11 (37%) 4-6 nights/week and 9 (30%) every night/week. Overall 7 patients (23.3%) were affected by adenoid hypertrophy (AH), 4 (13.3%) by tonsillar hypertrophy (TH) and 13 (43.3%) by AH and TH. We found a more vertical position of the hyoid bone to the mandibular plane (H⊥VT) in patients with a higher frequency (7.3±2.7 vs 7.6±3.7 vs 10.9±2.5 in children snoring 3 nights/week, 4-6 nights/week and every night/week respectively; p = 0.032). Concerning nasal patency significant correlations were found with ANB (maxillary and jaw position with respect to the cranial base), NS∧Ar (growth predictor), sumangle, FMA (total divergence), SnaSnp∧GoMe (inferior divergence), BaN∧PtGn (facial growth pattern), Phw1_PsP (posterosuperior airway space), AHC3H (the horizontal distance between the most anterosuperior point of the hyoid bone and the third cervical vertebra). CONCLUSION: The present study supports the relationship between nasal obstruction and specific craniofacial characteristics in children with primary snoring and lead us to hypothesize that nasal obstruction might explain the indirect link between snoring and cephalometric alterations.

Benign paroxysmal positional vertigo and post-treatment quality of life.

Benign paroxysmal positional vertigo is probably the most common cause of vertigo. It is characterized by acute short-lived episodes of severe vertigo in association with change in the position of the head. This condition is benign, and after the repositioning procedure, the cure rate is between 70 to 80%. Numerous studies describe the association between vertigo and social handicap and emotional disturbance. In our study, we report for the first time the level of anxiety and social consequences, tested with the Hamilton anxiety scale and vertigo handicap questionnaire, in a group of patients who had suffered only from positional vertigo and were clinically cured when the questionnaires and test were administered. The important role played by psychological factors in maintaining or increasing the social consequences and perception of vertigo is revealed in this study.

Meningiomas of the internal auditory canal: two case reports.

Meningiomas represent 3 to 12% of the tumors that involve the cerebellopontine angle and internal auditory canal (IAC). Intracanalicular meningiomas, however, are rare. Only 10 well-documented cases have been reported in the English literature. The differential diagnosis includes acoustic neuromas, facial nerve neuromas, hemangiomas, lipomas, and meningiomas. We report two new cases of intracanalicular meningioma. Both patients had unilateral tinnitus. In case 1, the patient also experienced sensorineural hearing loss with unilateral tinnitus. In case 1, the lesion appeared hyperintense on T1-weighted and hypointense on T2-weighted magnetic resonance images. In case 2, the patient had an enhancing lesion in the right IAC. The tumors were moderately cellular, and meningeal whorls and meningothelial inclusions were present. Immunohistochemical staining revealed the tumors to be positive for epithelial membrane antigen (EMA) and negative for S-100 protein. The radiologic findings that help distinguish a meningioma from other lesions are reviewed.
