Moderate-High Blood Eosinophilia Is Associated with Increased Hospitalization and Other Asthma Comorbidities.

(1) Background: Eosinophilia has traditionally been linked to eosinophilic asthma, for which it is the gold-standard prognostic biomarker. However, the association between eosinophilia and the presence of other diseases and comorbidities is yet unclear. (2) Methods: For this retrospective study, we reviewed the electronic medical records of 49,909 subjects with blood eosinophilia to gather data on the presence of asthma, COPD, sleep apnea, tuberculosis, dyslipidemia, hypertension, and other cardiovascular diseases and severe CRSwNP among these subjects. Demographic features including age, sex, and smoking habits were collected, as well as the number of hospitalizations and emergency department visits. T-tests, ANOVA, Fisher test, and logistic regression models were used. (3) Results: For all age groups studied, eosinophilia was significantly more prevalent among asthmatic subjects than nonasthmatics, especially in patients also presenting CRSwNP, hypertension, and dyslipidemia. The likelihood of developing asthma, COPD, and CRSwNP, and hospitalization, was increased when BEC was above 600 eosinophils/µL. The association between asthma, CRSwNP, and BEC was corroborated by multiple logistic regressions models. (4) Conclusions: We demonstrated the association of having over 600 blood eosinophils/µL with a higher number of hospitalizations and comorbidities (CRSwNP and COPD), which proves that BEC is a highly useful parameter to consider in subjects who present blood eosinophilia.

Transoral removal of submandibular hilar lithiasis: results on the salivary duct system, glandular parenchyma, and quality-of-life recovery.

OBJECTIVE(S): To confirm that hilar transoral submandibular sialolitectomy (TOSL) is the first treatment option for submandibular hilar lithiasis (SHL) in terms of glandular parenchyma recovery, salivary system restoration, and patient quality of life (QoL) improvement. METHODS: Depending on whether the stone was easily palpable, TOSL was carried out with or without sialendoscopy. For the first time in the literature, Magnetic Resonance Sialography (MR-Si) was performed before and after TOSL, to evaluate stone characteristics, glandular parenchyma status, hilum dilation and main duct recanalization. Radiological data was examined independently by two radiologists. COSQ, a recently validated and specific questionnaire, was used to assess associated QoL. RESULTS: Between 2017 and 2022, 29 TOSL patients were examined. With a high interobserver correlation, MR-Si was confirmed as a very useful radiological test in the pre- and post-surgical evaluation of SHL. The salivary main duct was completely recanalized in all cases. The presence of lithiasis was found in 4 patients (13.8%). After surgery, the majority of patients (79.31%) had hilum dilation. There was a statistically significant improvement in parenchyma status, but no significant progression to glandular atrophy. After surgery, COSQ mean values always improved (22.5 to 4.5). CONCLUSIONS: TOSL is the ideal surgical technique for the management of SHL, resulting in improved parenchymal inflammatory changes, recanalization of Wharton's duct, and enhancement patients' QoL. As a result, before removing the submandibular gland, TOSL should be considered as the first treatment option for SHL.

In vivo effect of mouthwashes on viable viral load of SARS-CoV-2 in saliva: a pilot study.

Current data on the efficacy of antiseptic mouthwashes to reduce viral load are contradictory. Firstly, in vitro data indicate very strong virucidal effects that are not replicated in clinical studies. Secondly, most clinical studies identify a limited effect, do not include a control/placebo group, or do not evaluate viral viability in an infection model. In the current manuscript, we perform a double-blind, randomized clinical trial where salivary viral load was measured before and after the mouthwash, and where saliva samples were also cultured in an in vitro infection model of SARS-CoV-2 to evaluate the effect of mouthwashes on viral viability. Our data show a 90-99% reduction in SARS-CoV-2 salivary copies with one of the tested mouthwashes, although we show that the remaining viruses are mostly viable. In addition, our data suggest that the active ingredient concentration and the overall excipients' formulation can play an important role; and most importantly, they indicate that the effect is not immediate, being significant at 15 min and having maximum effectiveness after 1 h. Thus, we show that some oral mouthwashes can be useful in reducing viral transmission, although their efficacy must be improved through refined formulations or revised protocols.

Prevalence of hearing protection use and subjective auditory symptoms among Spanish classical orchestral musicians.

INTRODUCTION: Sensorineural hearing loss caused by exposure to noise is one of the most frequent causes of deafness. Professional musicians have significant occupational exposure to high levels of noise. Use of hearing protection among musicians could substantially prevent hearing damage, though the rate of use is quite low. METHODS AND MATERIAL: A questionnaire on the use of protective hearing devices, hearing care, and subjective judgments of hearing difficulties was completed by a group of classical musicians from Spain. We analysed the frequency of device use by instrument based on contingency tables analysed by χ2 tests. RESULTS: One hundred and ninety-four Spanish classical orchestral musicians voluntarily completed the questionnaire. The percentage of musicians who reported using hearing protection in our survey was very low and varied with the type of instrument played. However, we found a high prevalence of subjective auditory disorders within this group. CONCLUSION: Few Spanish musicians use hearing protection. Training on hearing-loss prevention in this field and better protective devices could increase device use and improve the auditory health of this group.

Everything but the squeal: a guide for head and neck surgery training on the live porcine model.

PURPOSE: The porcine model has been demonstrated to be cost-effective for head and neck surgery training. There is no literature describing the porcine head and neck anatomy. The purpose of this study is to provide a porcine surgical guide for training head and neck residents. METHODS: Five head and neck dissections were performed under general anesthesia on the Large White pig model in the animal facilities of the University Hospital Fundación Jiménez. Sessions were photographed, and reference anatomical measurements were taken. RESULTS: The sternum-chin distance (x = 15.80 cm, σ = 0.44), chin-chin distance (x = 11.10 cm, σ = 2.30), prelaryngeal musculature length (x = 10.30 cm, σ = 1.92) and supraomohyoid triangle area (x = 7.07 cm2, σ = 3.91) were among the measurements obtained. The porcine head and neck anatomy was detailed. CONCLUSIONS: Head and neck porcine anatomy was thoroughly described, with emphasis on the similarities with human anatomy. The porcine model is capable of simulating human anatomy for surgery training.

Análisis del rendimiento de la secuenciación del exoma clínico en hipogonadismo hipogonadotropo congénito teniendo en cuenta el grado de alteración del olfato / Diagnostic yield of clinical exome sequencing in congenital hypogonadotropic hypogonadism considering the degree of olfactory impairment

Introducción: El hipogonadismo hipogonadotropo congénito (HHC) puede presentarse de manera aislada o acompañado de anosmia o de malformaciones congénitas. Más de 30 genes han sido implicados en la patogénesis de HHC; además, se han descrito varios patrones de herencia asociados a esta entidad. La creciente disponibilidad de técnicas de secuenciación masiva (NGS) ha permitido que aumente el rendimiento diagnóstico del estudio de esta patología. Pacientes y métodos: Evaluamos el rendimiento diagnóstico del estudio mediante NGS de pacientes con HHC, usando la secuenciación del exoma clínico filtrado por paneles virtuales. Además, se analizó si el diseño de estos paneles, basándose en la presencia/ausencia de microsmia/anosmia aumentaban este rendimiento diagnóstico. Resultados: Usando un panel virtual compuesto de 34 genes pudimos confirmar el diagnóstico de HHC en cinco de nueve pacientes (55%). En dos de nueve individuos (22%) estudiados se obtuvieron resultados no concluyentes. La ausencia/presencia de microsmia para la elección de genes a estudiar no mejora el rendimiento diagnóstico. Conclusiones: El abordaje del estudio genético de pacientes con HHC puede variar en función de las técnicas disponibles en cada centro, por lo que la sensibilidad del test utilizado variará, dependiendo si se utiliza secuenciación de paneles, exoma clínico o exoma completo. El análisis de todos los genes relacionados con HHC independientemente de la presencia/ausencia de microsmia pareciera el abordaje con mejor rendimiento. (AU)

Introduction: Congenital hypogonadotropic hypogonadism (CHH) can present alone or in association with anosmia or other congenital malformations. More than 30 genes have been identified as being involved in the pathogenesis of CHH with different patterns of inheritance, and the increasing availability of next generation sequencing (NGS) has increased the diagnostic yield. Methods: We analysed the diagnostic yield of NGS in patients with CHH using the clinical exome filtered with virtual panels. We also assessed whether designing panels based on the presence/absence of microsmia increased the diagnostic yield. Results: The use of a 34-gene virtual panel confirmed the diagnosis of CHH in 5 out of 9 patients (55%). In 2 out of 9 (22%), the findings were inconclusive. Applying the presence/absence of microsmia criterion to choose genes for analysis did not improve the diagnostic yield. Conclusions: The approach to the genetic study of patients with CHH varies depending on the resources of each healthcare facility, so the sensitivity of testing may vary substantially depending on whether panels, clinical exome sequencing or whole exome sequencing (WES) are used. The analysis of every genes related to CHH regardless of the presence/absence of microsmia seems to be the best approach. (AU)

Usefulness of endonasal flaps and grafts in skull base surgery. Consensus document.

INTRODUCTION: Skull base reconstruction is one of the greatest challenges extended endonasal endoscopic surgery. Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes. OBJECTIVES: The target is to create a consensus document on the use of different endonasal flaps and grafts in the skull base surgery. MATERIAL AND METHODS: Literature review of the most relevant free grafts and vascularized flaps from the endonasal fossa. Analysis using the Delphi method on the use of the different endonasal resources for endoscopic repair of skull base defects. RESULTS: We obtained two results: 1) A selection of the most representative flaps and grafts from the endonasal fossa, describing origin, surface and indications, based on a literature review. 2) A consensus document, using Delphi methodology, with general considerations (2), recommendations (10) and limitations (6) of the different endonasal flaps and grafts. CONCLUSIONS: We present the first consensus document in the field of extended endonasal endoscopic surgery using the Delphi method as a working tool. We highlight the usefulness of the nasoseptal flap together with other endonasal flaps and grafts for skull base reconstruction.

Effect of oral antiseptics in reducing SARS-CoV-2 infectivity: evidence from a randomized double-blind clinical trial.

ABSTRACTBackground: In vitro studies have shown that several oral antiseptics have virucidal activity against SARS-CoV-2. Thus, mouthwashes have been proposed as an easy to implement strategy to reduce viral transmission. However, there are no data measuring SARS-CoV-2 viability after mouthwashes in vivo. METHODS: In this randomized double-blind, five-parallel-group, placebo-controlled clinical trial, SARS-CoV-2 salivary viral load (by quantitative PCR) and its infectious capacity (incubating saliva in cell cultures) have been evaluated before and after four different antiseptic mouthwashes and placebo in 54 COVID-19 patients. RESULTS: Contrary to in vitro evidence, salivary viral load was not affected by any of the four tested mouthwashes. Viral culture indicated that cetylpyridinium chloride (CPC) significantly reduced viral infectivity, but only at 1-hour post-mouthwash. CONCLUSION: These results indicate that some of the mouthwashes currently used to reduce viral infectivity are not efficient in vivo and, furthermore, that this effect is not immediate, generating a false sense of security.Trial registration: ClinicalTrials.gov identifier: NCT04707742..

Epidemiologic, radiologic, and sialendoscopic aspects in chronic obstructive sialadenitis.

PURPOSE: Chronic obstructive sialadenitis (COS) is a recurring inflammation of the salivary gland. To date, there are no known predisposing factors for COS. Given the advances seen in radiology and sialendoscopy, we must update our knowledge of COS, analyzing factors that can favor its development. METHODS: We prospectively analyzed 333 patients who underwent sialendoscopy between 2012 and 2021. Epidemiologic, radiologic, and sialendoscopy-related factors were correlated. Suspected diagnosis was established based on the clinical and radiologic data. The final diagnosis was determined on the basis of sialendoscopic findings. RESULTS: The most common etiology of COS was stricture (40.8%). Lack of papilla distensibility (LPD) was also described as an etiology. COS was related to patient gender and age. Submandibular gland involvement was significantly more associated with lithiasis and LPD, while COS of the parotid gland was most frequently caused by stricture. Radioiodine sialadenitis and Sjögren's syndrome were significantly associated with stricture. MR sialography (MR-Si) showed the best overall sensitivity and specificity. CONCLUSION: In our series, stricture was the most common cause of COS. We describe LPD as a frequent cause of COS in this series; ours is the first study to report this finding. There was a significant association between the salivary gland involved, patient sex and age, and the cause of COS. MR-Si showed the greatest diagnostic yield.

A live porcine model for surgical training in tracheostomy, neck dissection, and total laryngectomy.

OBJECTIVES: Head and neck surgery is associated with a steep learning curve, creating a need for effective training methods. Live animal models can be useful in acquiring the required skills and techniques to perform tracheostomy, neck dissection, and laryngectomy. The aim of this study is to assess the feasibility and usefulness of a porcine model to teach tracheostomy, neck dissection, and laryngectomy, describing the similarities between a swine head and neck surgical model and the human cervical area. METHODS: Twelve surgical training sessions were held with the use of a live porcine model maintained under general anaesthesia; a total of 39 procedures were performed. In each session, one otolaryngology resident per year performed a procedure to acquire the targeted competencies for their respective year of training. Each procedure was time recorded and evaluated based on a modified Objective Structured Assessment of Technical Skills. Linear regression was used to analyse the data and express the results as percentages. RESULTS: Training exercises were performed in shorter times over the study period. A 9% reduction in the time spent was observed. There was a global improvement in the evaluation made by OSATS score of 6% in the first period (2018-2019) and 58% in the second period (2019-2020). CONCLUSION: The porcine model was both manageable and helpful in providing training despite slight anatomical differences between human beings and pigs. However, more studies are necessary to guarantee that the competencies acquired with this type of training are transferable to real-life interventions. LEVEL OF EVIDENCE: Level 5.

Incidence and risk factors for radioactive iodine-induced sialadenitis.

BACKGROUND: Radioactive iodine (131I) is one of the treatments of hyperthyroidism and differentiated thyroid carcinoma (DTC). Swelling of salivary glands are one of the possible side effects of this treatment, known as radioactive iodine-induced sialadenitis (RAIS). The prevalence of RAIS varies widely and no specific risk ratio has been established. OBJECTIVES: To determine the incidence of RAIS, analysing the epidemiological data and tumour- and treatment-related factors that may influence the development of the disease. MATERIAL AND METHODS: 197 patients who received radioiodine treatment between 2015 and 2017 were studied (76.6% women). The variables studied were age, gender, weight, height, and body mass index; presence of high blood pressure, dyslipidemia, diabetes, and thyroid diseases; cumulative radioiodine dose, presence of sialadenitis, affected salivary gland, and the time of onset. RESULTS: 14 patients developed sialadenitis (78.6% women), all with DTC. The incidence of sialadenitis was 3.4% overall and 6.3% among DTC patients. Furthermore, we found that higher cumulative radioiodine doses confer a greater risk of developing sialadenitis, with a hazard ratio of 1.009 (p = .001). No association was found between the epidemiologic data studied and sialadenitis. CONCLUSIONS: In this series, a dose-dependent relationship was found between radioiodine treatment and sialadenitis.

p16 Influence on Laryngeal Squamous Cell Carcinoma Relapse and Survival.

OBJECTIVE: (1) To identify p16 protein in laryngeal squamous cell carcinoma (LSCC) specimens and to correlate it with the presence of human papillomavirus (HPV) found in these specimens from a previous study. (2) To analyze p16 impact on 10-year overall and disease-free survival. STUDY DESIGN: Retrospective case series with oncologic database chart review. SETTING: Academic tertiary care hospital. SUBJECTS: A total of 123 samples of LSCC (taken from the glottis only) from patients treated with primary surgical resection between 1977 and 2005. METHODS: p16 protein expression was analyzed through immunohistochemistry and compared with the presence of HPV established in our previous studies. Results were compared with histologic, clinicopathologic, and survival parameters, with a 10-year follow-up. RESULTS: Of the samples, 39.02% were positive for p16, but only 11.38% were positive for both p16 and HPV. The p16+ cohort showed a significant improvement in disease-free survival ( P = .0022); statistical significance was not achieved for overall survival. p16+ cases had fewer relapses over time, with no relapses after a 2-year follow-up. Age at the time of diagnosis and tobacco consumption were the only epidemiologic factors that influenced overall survival. CONCLUSION: The expression of p16 protein was a beneficial prognostic factor for disease-free survival among patients with LSCC of the glottis, with no relapses after a 2-year follow-up.

Microscopic approach for repairing nasal septal perforations using bilateral advancement flaps.

BACKGROUND: Septal perforations consist in an anatomic defect of the mucosal, cartilaginous and/or bone tissues of the nasal septum. A huge variety of approaches and techniques for nasal perforation repair have been reported. METHODOLOGY/PRINCIPAL: Between January 2008 and January 2017, 38 patients were treated for nasal septal perforation in Department of Otorhinolaryngology Head and Neck Surgery, Fundación Jiménez Díaz University Hospital, Madrid, Spain. A novel approach is presented based on microscope. Septal perforation closure was performed with endonasal bilateral advancement flaps-established technique and autologous cartilage and muscle temporal fascia grafts. We performed a retrospective review of closure rates and complications. RESULTS: A postoperative follow-up of at least 12 months was performed in 37 patients. The mean size of perforation was 1.33 cm. After the withdrawal of the silicone splints, perforations were completely closed in all cases. However, during the follow-up, four patients resulted in a reperforation, so our closure rate was 89.19%. For all cases, symptoms related to septal defect were solved. Only one case was reported of local infections that was resolved with antibiotics in a few days. CONCLUSIONS: Microscopic approach of septal perforation closure using bilateral advancement flaps can be an affordable technique with a high percent of success and low rate of complications.

Incomplete cavernous sinus syndrome as the initial manifestation of a previously undetected metastatic prostate adenocarcinoma.

BACKGROUND: Cavernous sinus syndrome presents as unilateral ophthalmoplegia associated with sympathetic denervation, pain, paresthesias, and V1 and V2 distribution numbness. The etiology may be vascular, inflammatory, infectious, and, less commonly, neoplastic (metastatic). METHODS: We report a patient with incomplete cavernous sinus syndrome as the initial manifestation of previously undetected metastatic prostate adenocarcinoma. RESULTS: A 59-year-old man presented with a 2-month history of left hemicranial headaches with ptosis and binocular diplopia. Clinical evaluation found left third, fourth, and sixth cranial nerve palsy with mydriasis and ptosis. An MRI showed an enhancing lesion at the clivus with infiltration of left cavernous sinus. A trans-sphenoidal biopsy was performed, leading to diagnosis of metastatic prostate adenocarcinoma. The patient underwent treatment and achieved clinical improvement. CONCLUSIONS: In middle-aged men, it is important to include metastatic prostate adenocarcinoma in the differential diagnosis of cavernous sinus syndrome, even in the absence of primary tumor diagnosis.
