Diseño y evaluación de las propiedades antibacterianas de un prototipo de molde de audífono que incorpora cobre en su manufactura
Introduction: External otitis of infectious etiology among hearing aid users is a common motive of otolaryngology consultation. Antibacterial properties described copper, they have motivated the development of clinical applications of this metal. Aim: Evaluate the antibacterial capacity of copper-based ear molds manufactured with different materials such UV sensitive polymers, silicone and acrylic incorporating metallic copper, in an experimental system in vitro. Material and method: Ear molds with and without copper, were inoculated with different concentrations of microorganisms (S aureus and P aeruginosa) and determine the percentage of bacterial adherence to different contact times (4-8 and 12 hours). Results: There was significant reduction in bacterial adhesion to copper molds than those without copper, independent of the material, the type of microorganism and the bacterial inoculum. Discussion: The decrease in bacterial adherence on prototypes with copper, can be attributed to inhibitory activity on microorganisms depending on their concentration and contact time, exerting its effect by diffusion through the various materials. Conclusion: With these results, is necessary the development of clinical studies focused on checking whether the use of hearing aids with copper decreases external otitis of infectious origin.

Comparación de las amplitudes y latencias de la onda V del potencial evocado auditivo de tronco cerebral obtenidas a través de estímulos clic y CE-Chirp®
Introduction: The auditory brainstem response (ABR) has become a standard procedure in the audiological evaluation. For decades the most widely used stimulus was the click, but recently the use of chirp stimulus has been proposed for obtain more efficient results. Aim: To compare the amplitudes and latencies of wave V of ABR obtained through click and CE-Chirp® stimuli at different intensities. Material and method: A quantitative, not experimental, transversal and descriptive study was conducted with 17 subjects who were evaluated with ABR using click and CE-Chirp® stimuli. Results: Wave V larger amplitudes were verified for stimulus CE-Chirp®, in all the evaluated intensities (80, 60, 40, 30 and 20 dBnHL). Shorter latencies of wave V were obtained for CE-Chirp® stimuli only at 80 and 60 dBnHL, while it was found that the remaining intensities showed lower latencies with click stimuli. Conclusions: There are significant differences between latencies and amplitudes of the wave V obtained with CE-Chirp® and click stimuli. While the CE-Chirp® stimuli provides faster results for most accurate electrophysiological threshold, click stimuli would be appropriate to conduct site of the lesion testing.

Tumor neuroectodérmico primitivo de cavidad nasal
Primitive neuroectodermal tumors are rare malignancies arising from embryonic neural crest cells. They share characteristics with extraosseous Ewing sarcoma. They usually occur in children and young adults and the most common location is the thoracopulmonary region, abdomen and extremities. These tumors have significant aggressiveness, which determines their poor prognosis. The location in nasal fossa-paranasal cavities is anecdotal. Until now only one previous case has been reported in the located in the nasal fossa.

Glomangiopericitoma: Reporte de un caso
Glomangiopericytoma is an extremely rare sinonasal tumor, more common among elderly and women. Although its etiology and pathogeny are unknown, there are certain predisposing factors, such as arterial hypertension, pregnancy, trauma and corticosteroids. To diagnose this tumor, it is necessary imaging, histopathologic and inmunohistochemical studies. At the microscopic study, it is characterized by a prominent perivascular growth of oval-shaped or fusiform cells, arranged in short fascicles separated by capillary vessels of variable diameters, with staghorn-like ramifications, and lmmunohistochemistry positive mainly for actin, XIII-A factor and vimentin. Clinically, this tumor has a generally benign behavior, but with high recurrence percentage. We present the case of a 71 years old woman, with history of hypertension, who present in our center with a 5 years history of purulent rhinorrhea and right unilateral epistaxis, at the physical exam there is a polypoid mass in the right nasal fossa with rich vascularization, with no other findings. This tumor was resected entirely with endoscopic surgery. Histology and immunohistochemistry were compatible witch gomangiopericytoma. The patient evolve with remission of her symptoms and with no signs of recurrence at two-month follow-up.

Plasmocitoma extramedular del tabique nasal: Reporte de un caso y revisión bibliográfica
Plasmacytomas are malignant tumors characterized by abnormal proliferation of monoclonal plasma cells. They may originate in bone and soft tissue , called solitary bone plasmacytoma and extramedullary plasmacytomas (EMP) respectively. The latter represents less than 1% of all malignant disease of the head and neck, however, the report of these cases it is useful to cope with the shallow casuistics thereon. We report a case of EMP of the nasal septum in a man of 74 years with progressive nasal breathing difficulties and frequent epistaxis on the left side. A nasal speculoscopy was observed in tumor lift lobby smooth, gray, sessile surface. The biopsy showed it was a plasmacytoma. Subsequent studies reject the presence of multiple myeloma. This confirmed the diagnosis of EMP. The mass was completely dissected, radiation therapy is indicated and the patient had no adherence. Upon the same place a similar injury returns. Conclusion: Septum extramedullary plasmacytoma is a rare entity of a long natural history and represents a diagnostic and therapeutic challenge. Depending on the resectability of the lesion, combination therapy with surgery and radiation therapy is the treatment of choice.

Presencia de la celdilla supra-órbito-etmoidal: Revisión de la literatura a partir de un caso
The supraorbital ethmoid cell its an anatomical variation with different frecuency for diverse populations. It represents a challenge for the endoscopical functional :surgery of the frontal sinus. The supraorbital ethmoid cell presents an estable anatomical relationship with the anterior ethmoidal artery, serving as a dependable anatomical marker for the surgical approach. We stand out the importance to consider the presence of bony septations in the frontal sinus that might suggest the presence of the supraorbital ethmoid cell. We introduce a clinical case from a patient who had an expansive process from a mucocele in the supraorbital ethmoid cell.

Anatomía, fisiología y rol clínico de la corteza vestibular
The vestibular system, thanks to its peripheral organs, allows us to properly process the angular head movements and linear acceleration in order to give us a proper orientation in space. The information from these sensory inputs is routed to the vestibular nuclei and thence ascending tracts of the brainstem, which communicate with the oculomotor nuclei of the thalamus and structures. Then the information goes to subcortical and cortical centers, which are eminently multisensory nature. The nature and function of these structures are controversial. In this review the main concepts and discoveries at the level of basic and clinical research generated cortical processing of vestibular stimulation are addressed.

Carcinoma basocelular metastásico
Basal cell carcinoma is the most frequent neoplasm worldwide. It's a slow growing and locally aggressive tumor, but it has a metastatic potential estimated between 0,0028 and 0,5%. The purpose of this study is to show the experience of a center in the management of this metastatic disease. Descriptive retrospective study of patients with metastatic basal cell carcinoma treated at the Instituto nacional del cancer from July2004 to July 2015. A revision of the literature was also made. 3 cases with this unusual disease during an 11 years period. The first one died at 42 months of follow up. There are 2 patients on follow up, 1 of them has lung metastatic disease after 29 months of follow up, and the last one is free of disease with 92 months of follow up. Metastatic basal cell carcinoma is an unusual entity, thus everyone that is involved in it's treatment, must be aware of this in order to do an early diagnosis. Surgery associated to radiotherapy are the mainstays of treatment. This disease should be managed on national referral centers.

Enmascaramiento clínico: Una revisión de la literatura
Adequate use of masking is key in the correct diagnosis of hearing loss. Various methods are suggested regarding the application of clinical masking, hence the need to review literature in order to reach a consensus. To critically review the specialized literature and international societies' recommendations regarding clinical masking. From August to November 2015, PUBMED, SciELO and Google Scholar articles on clinical masking methods used in tonal audiometries were consulted, as well as international organization guidelines, and literature in the area of Audiology. Hood's plateau method, later revised, received the most references. The modified versions consider the number of increments needed to determine the true threshold, and the occlusion effect. Optimized methods show the variations regarding interaural attenuation, need for masking, initial masking level, increments to reach "The Plateau", and the occlusion effect. Literature shows differences regarding when and how to use masking; however, common criteria can be established with reference to the levels of interaural attenuation, when to use masking, occlusion effect values and methodology. The plateau method proposed by Hood is still the most recommended. Yacullo's optimization is currently the one with the most references and recommendations in specialized literature.

Sonolocation during submandibular sialolithotomy
Objectives/Hypothesis
Ultrasound is a proven tool for diagnostic and therapeutic purposes for treatment of salivary gland pathology. It is also useful for localization of calculi during submandibular gland transoral sialolithotomy when calculi cannot easily be palpated. Our objective was to determine the efficacy of sialolith localization using ultrasound during submandibular gland sialolithotomy.
Study Design
Retrospective case series.
Methods
A study performed utilizing data compiled from 2009 through 2016 in a tertiary academic center. Treatment was completed in 164 patients with sialadenitis and sialolithiasis by submandibular gland transoral sialolithotomy in either the office (81%) or the operating room (19%). Ultrasound was used for localization of sialoliths during submandibular gland sialolithotomy. Main treatment outcomes studied were success of the procedure, complications, and follow‐up.
Results
Successful sialolithotomy was performed in (147 patients) 90% of cases. Complications were minimal and included stricture formation, which occurred in 3% (five patients) of cases, followed by ranula formation in 1.8% (three patients) of cases. There were no incidences of lingual nerve injury.
Conclusions
Ultrasound can be used effectively for precise sialolith localization intraoperatively.

Prognostic indicators of survival in sinonasal extranodal natural killer/T‐cell lymphoma
Objectives
Extranodal natural killer/T‐cell lymphoma (ENKTL) is a highly aggressive tumor of the sinonasal tract associated with poor overall survival (OS). This study expands upon epidemiologic, prognostic, and treatment factors for OS and disease‐specific survival (DSS), incorporating newly accessible chemotherapy data.
Methods
Retrospective population‐based cohort study performed on cases of sinonasal ENKTL identified through the Surveillance, Epidemiology, and End Results database. Univariate Kaplan‐Meier analysis and subsequent multivariate Cox‐regression analysis were performed to evaluate prognostic and treatment variables for OS and DSS.
Results
Four hundred and sixty cases of sinonasal ENKTL were identified. Five‐year OS and DSS were 46% and 56%, respectively. On multivariate analysis, higher Ann Arbor stage was associated with worse OS (P < 0.001) and DSS (P < 0.001), whereas administration of radiotherapy was associated with improved OS (P < 0.001) and DSS (P = 0.001). Additionally, a higher age at diagnosis was associated with reduced OS (P = 0.024). Chemotherapy was associated with improved OS (P < .01) and DSS (P = .04) for Ann Arbor stage I disease. Surgery was not associated with improved survival.
Conclusion
This represents the first study to investigate the use of chemotherapy for the treatment of sinonasal ENKTL using population‐based analysis. Radiation therapy and chemotherapy significantly improve survival in all Ann Arbor stage patients and early‐stage patients, respectively. Early‐stage disease is significantly associated with improved survival. With no established treatment regimen for sinonasal ENKTL, these findings suggest combination chemoradiation is an effective therapy for prolonged survival, especially in early stages of disease.

Speech intelligibility in patients with oral cancer: An objective baseline evaluation of pretreatment function and impairment
Abstract
Background
This study seeks to identify those factors that influence the pre‐therapeutic speech intelligibility in patients with oral squamous cell carcinoma (OSCC).
Method
A group of 172 patients (125 males, 47 females, mean age = 61 ± 11 a) with different OSCC stages ranging from T1 to T4 and N0 to N2 was examined for their speech intelligibility using a computerized measuring tool, and compared to a healthy reference group (30 males, 10 females, mean age = 59 ± 12 a).
Results
It was found that the pre‐therapeutic speech intelligibility in patients with OSCC is decreased when compared to a healthy collective. Two demographic factors that influence speech intelligibility could be identified: sex and age. It was determined that the only disease‐related factor that influences speech intelligibility before therapy is the location of the tumor.
Conclusion
The results of this study reveal that a preoperative speech intelligibility impairment in patients suffering from OSCC occurs independent of tumor stage, size of the tumor and infiltration status.

Management of laryngeal papillomatosis using coblation: another option of surgical intervention
Abstract
Purpose
Recurrent respiratory papillomatosis is a disease caused by the human papilloma virus (HPV). HPV is frequently localised in the larynx. The disease tends to recur and frequent intervention is usually required. Management modules include surgical intervention using microdebriders or laser ablation as well as adjuvant treatments which aim mainly at maintaining an adequate airway and secondly to manage dysphonia caused by the growth on the vocal folds. In this pilot study, another surgical modality is trialled using plasma-mediated radio-frequency ablation (coblation).
Methods
Retrospective study examining management of 15 adult patients diagnosed with recurrent laryngeal papillomatosis and surgically treated using coblation. One patient required multiple procedures. Pre-operative assessment in voice clinic evaluating voice quality and its impact on patients' life-quality using voice parameters and self-assessment questionnaires. Follow-up post-operatively using the same parameters from 4 to 6 weeks after surgery until up to 2 years later to check recurrence rate. No other adjuvant treatment was used and all patients received post-operative voice therapy.
Results
78.6% of patients did not show evidence of recurrence during the study period. Improvement in voice handicap following first intervention is reported and recurrence rate in the rest of the sample reported.
Conclusions
The results of this small sample seem to support the previous small studies' findings that coblation is a good excisional technique to use for removal of laryngeal papillomatosis. Recurrence rates seem to be slightly lower than rates reported in the literature for the other surgical modalities.

Anesthesia and ventilation options for flex robotic assisted laryngopharyngeal surgery
Publication date: Available online 22 February 2019
Source: American Journal of Otolaryngology
Author(s): Yosef Krespi, Victor Kizhner, Robert Koorn, Anthony Giordano
Abstract
Background
Transoral treatment of benign and malignant lesions of laryngopharynx has limitations in exposure and access, partially due to the endotracheal tube (ETT). With a proper airway control to tailor ventilation and maximize exposure, transoral Flex robotic surgery (FLEX), using its 3D camera and instruments, can expand its ability. Choosing the right ETT, including a novel concept of using jet ventilation (JV) in FLEX, and placement technique can allow augmentation of the advantages that robotic surgery offers.
Methods
Chart review of FLEX assisted procedures was performed. Attention was given to demographics, all events of airway manipulation and ventilation type, procedures performed and outcomes including adverse effects.
Results
Fifty-two patients underwent eighty procedures. The airway was manipulated sixty-four times to include 8 JV. All possible FLEX instruments including CO2 laser were used. Three novel possible indications for trans-oral robotic surgery including the feasibility of JV in FLEX procedures were shown.
Conclusions
Lesions of the tongue base, hypopharynx, larynx and trachea have the possibility to be managed with adequate exposure with minimal obstruction from ETT. Robotic HD camera permits both the surgeon and anesthesiologist to observe surgery and safely monitor the airway. An algorithm was developed for selecting ideal ventilation method for different procedures. The FLEX and the utilization of JV allows flexibility of two instruments without obstruction.

Abstract
Objective
Since reports on surgical results for pediatric obstructive sleep apnea (OSA) in Japan are insufficient for debate, this study aimed to evaluate the feature of Japanese OSA children and surgical result and document whether is obesity and affecting factor similar to non-Asian countries.
Methods
This is a retrospective study. A total of 242 children with OSA at the Department of Otolaryngology and the Good Sleep Center, Nagoya City University Hospital and the Toyohashi Mates Sleep Disorders Center were included in the study. All children underwent pre- and postsurgical polysomnography. OSA was defined as an apnea hypopnea index (AHI) 5 or greater. Pre- and postsurgical respiratory parameters were compared using paired T test.
Results
Normalization of breathing after surgery for OSA children was 40% with AHI < 2 and 85% with AHI < 5. Japanese OSA children are not as obese as OSA children in many non-Asian countries. However, the normalization of breathing as a result of surgery in Japanese OSA children does not differ much from non-Asian countries.
Conclusion
Japanese pediatric OSA that is not normalized by surgery may be affected by factors other than obesity.

Abstract
Introduction
Cortical auditory evoked potentials have been increasingly used in research and audiological routines. However, there is a lack of studies with a large number of children who are stratified by age group. These would help clarify the variations in latency and amplitude of cortical auditory evoked potentials, and thus help establish reference values in children of different ages.
Objective
To identify the variation in latency and amplitude of the cortical auditory evoked potentials and to establish reference values for the pediatric population.
Methods
This was a cross-sectional study. Subjects were born at term and presented with no auditory complaints. A total of 105 children, of up to 6 years and eleven months old, who were divided into 7 age groups, named 1, 2, 3, 4, 5, 6 and 7, participated in the study. The tests were carried out using Biologic Navigator Pro. Initially, brainstem auditory evoked potential testing was performed in order to investigate the electrophysiological threshold of the subjects. Then, cortical auditory evoked potentials were elicited through oddball paradigm with tone burst differing in frequency, 750 Hz (frequent) and 1000 Hz (rare), and stimuli differing in speech: /ba/ (frequent) and /da/ (rare). In this study, descriptive and comparative analyzes of tonal and speech stimuli were performed for the age groups.
Results
Significant differences were observed when comparing cortical auditory evoked potentials with speech stimulus in the right ear for P2 amplitude, for P1 latency the left ear, for P2 amplitude of the left ear; and for P1 amplitude of the left ear when performed with tonal stimuli.
Conclusion
The obtained results can be considered as reference values of latency and amplitude of cortical auditory potentials in infants and children, and be used for monitoring their cortical auditory development.

Abstract
Introduction
Mucosal contact headache is a referred pain that arises from contact between the nasal septum and the lateral nasal wall. Evidence supports the role of substance P in a contact headache such that release of substance P from sensory nerve endings causes inflammation and allergy.
Objective
This study aimed to determine possible differences in substance P levels in inferior turbinate hypertrophy creating a contact headache.
Methods
28 patients who had contact headaches (Study Group) and 16 volunteers with no complaints were included in the study. Substance P levels in the inferior turbinate tissue samples were quantified using a commercially available substance P EIA kit.
Results
In the study group average substance P levels were 2.65 ± 0.27 pg/mg tissue (range: 0.61–5.44) and in the control group it was 1.77 ± 0.27 pg/mg tissue (range: 0.11–4.35). The difference was statistically significant between the two groups (p = 0.0215). Average preoperative headache group visual analog scale scores was 5.93 ± 0.38 (2–9) and the turbinate volume was 6.56 ± 0.35 cm3 (3.50–10.30). The control group turbinate volume was 4.71 ± 0.39 cm3 (2.50–7.70). We found a correlation between the visual analog scale scores and substance P levels such that substance P levels were higher in visual analog scale scores above 5 (p = 0.001).
Conclusion
This study demonstrates the relationship between intranasal contact headaches and increased mucosal substance P levels. We also found that there is no correlation with substance P levels and volume of the inferior turbinate.
Resumo
Introdução
A cefaleia por ponto de contato da mucosa é uma dor direcionada que surge do contato entre o septo nasal e a parede nasal lateral. Evidências corroboram o papel da substância P na cefaleia de contato, de tal forma que a liberação da mesma a partir de terminações nervosas sensoriais possa causar inflamação e alergia.
Objetivo
O objetivo deste estudo foi determinar possíveis diferenças nos níveis da substância P na hipertrofia de conchas inferiores em relação à cefaleia de contato.
Método
28 pacientes que apresentaram cefaleia por ponto de contato (Grupo Estudo) e 16 voluntários sem queixas foram incluídos no estudo. Os níveis de substância P nas amostras de tecido da concha inferior foram quantificados utilizando-se um kit substância P EIA, comercialmente disponível.
Resultados
No grupo do estudo, os níveis médios de substância P foram 2,65 ± 0,27 pg/mg de tecido (variação: 0,61–5,44) e no grupo controle foram de 1,77 ± 0,27 pg/mg de tecido (variação: 0,11-4,35), e a diferença foi estatisticamente significante entre os dois grupos (p = 0,0215). O escore médio da escala visual analógica do grupo de cefaleia pré-operatória foi de 5,93 ± 0,38 (2–9) e o volume das conchas foi de 6,56 ± 0,35 cm3 (3,50–10,30). O volume da concha do grupo controle foi de 4,71 ± 0,39 cm3 (2,50 ± 7,70). Encontramos uma correlação entre o escore da escala visual analógica e os níveis de substância P, de modo que os níveis de substância P foram maiores nos escores da escala visual analógica acima de 5 (p = 0,001).
Conclusão
Este estudo demonstra a relação entre cefaleias por contato intranasais e níveis aumentados de substância P nas mucosas. Também observamos que não há correlação com os níveis de substância P e o volume da concha inferior.

Abstract
Importance: Patients 65 years or older are the most frequent users of operative resources and are also the most vulnerable to postoperative adverse events (AEs). Frailty indices are increasingly being used for preoperative risk stratification within head and neck cancer surgery, but most models lack a multifactorial basis and cannot be directly applied to clinical practice. A practical risk index is needed for clinicians to gauge risk factors preoperatively.
Objective: To develop a preoperative risk index of short-term major postoperative AEs for patients undergoing head and neck cancer surgery.
Design: Cohort analysis of patients from multiple medical centers undergoing inpatient ablative or reconstructive head and neck cancer surgery and registered in the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) from 2006 to 2016.
Exposures: Inpatient ablative or reconstructive head and neck cancer surgery.
Main Outcomes and Measures: Sociodemographic, frailty-related, and surgical factors in the derivation cohort were evaluated using simple and multiple logistic regression. Risk factors were subsequently integrated into a preoperative head and neck surgery risk index (HNSRI) and compared with existing models using the validation cohort. A composite variable of major postoperative AEs was used, including death within 30 days of surgery.
Results: A total of 43 968 operations were found using the ACS NSQIP database. Of these, 12 569 cases were excluded as non-head and neck cancer or emergency surgery. Of the included 31 399 operations reviewed, the mean (SD) patient age was 56.9 (15.4) years, and 16 994 of the patients were women (54.1%). A total of 4556 (14.5%) patients had a major postoperative AE, and 209 (0.7%) died. Older age, male sex, smoking, anticoagulation, recent weight loss, functional dependence, free-tissue transfer, tracheotomy, duration of surgery, wound classification, anemia, leukocytosis, and hypoalbuminemia were independently associated with major AEs or death on multiple regression analysis (C statistic, 0.83). The area under the curve of the HNSRI to predict major AEs including death using the validation cohort (n = 15699) was 0.84 (95% CI, 0.83-0.85) with a sensitivity of 80.1% (95% CI, 79.4%-80.8%) and specificity, 72.3% (95% CI, 70.3%-74.2%). The HNSRI outperformed existing risk models for prediction of AEs: delta C index of the HNSRI to the modified frailty index 11, 0.23 (95% CI, 0.22-0.25); the American Society of Anesthesiologists classification, 0.14 (95% CI, 0.13-0.16); and the ACS risk calculator, 0.02 (95% CI, 0.01-0.03).
Conclusions and Relevance: The proposed HNSRI demonstrated a high sensitivity and specificity for major postoperative AEs and death in the studied population. This risk index can be used to counsel patients awaiting head and neck cancer surgery.

Eosinophilic Esophagitis-A Primer for Otolaryngologists.
JAMA Otolaryngol Head Neck Surg. 2019 Feb 21;:
Authors: Kumar S, Choi S, Gupta SK
Abstract
Importance: Eosinophilic esophagitis (EoE) is a chronic, inflammatory condition of the esophagus. Prevalence of EoE is on the rise and, owing to its associated extragastrointestinal manifestations and comorbidities, otolaryngologists are increasingly encountering this condition in their practice.
Observations: Symptoms of EoE are vague and vary greatly based on patient's age. The gastrointestinal symptoms include dysphagia, food impaction, feeding difficulties, symptoms mimicking gastroesophageal reflux, abdominal pain, vomiting, and failure to thrive. Several otolaryngologic symptoms are associated with EoE including rhinosinusitis, chronic cough, recurrent croup, hoarseness, and other aerodigestive symptoms refractory to gastroesophageal reflux therapy. Eosinophilic esophagitis is also frequently associated with other atopic conditions, such as asthma, eczema, and food allergies. The diagnosis is made on endoscopy with biopsies that reveal eosinophil-predominant esophageal inflammation. There are 3 major treatment approaches to EoE, commonly referred to as the 3 Ds: diet, drugs, and dilation. Untreated inflammation of esophagus from EoE can result in irreversible structural damage to the esophagus, leading to fibrosis, strictures, and impaired esophageal function.
Conclusions and Relevance: Eosinophilic esophagitis is now a fairly prevalent condition with considerable morbidity. Otolaryngologists should be familiar with the various clinical presentations of this condition in different age groups. Early diagnosis and treatment of this condition is a key for avoiding or postponing its complications.

Abstract
Importance: Head and neck cancer (HNC) is more common among socioeconomically disenfranchised individuals, making financial burden particularly relevant.
Objective: To assess the financial burdens of HNC compared with other cancers.
Design, Setting, and Participants: In this retrospective review of nationally representative, publicly available survey, data from the Medical Expenditure Panel Survey were extracted from January 1, 1998, to December 31, 2015. A total of 444 867 adults were surveyed, which extrapolates to a population of 221 503 108 based on the weighted survey design. Data analysis was performed from April 18, 2018, to August 20, 2018.
Exposures: Of 16 771 patients with cancer surveyed (weighted count of 10 083 586 patients), 489 reported HNC (weighted count of 261 631).
Main Outcomes and Measures: Patients with HNC were compared with patients with other cancers on demographics, income, employment, and health. Within the HNC group, risk factors for total medical expenses and relative out-of-pocket expenses were assessed with regression modeling. Complex sampling methods were accounted for with weighting using balanced repeated replication.
Results: A total of 16 771 patients (mean [SD] age, 62.3 [18.9] years; 9006 [53.7%] female) with cancer were studied. Compared with patients with other cancers, patients with HNC were more often members of a minority race/ethnicity, male, poor, publicly insured, and less educated, with lower general and mental health status. Median annual medical expenses ($8384 vs $5978; difference, $2406; 95% CI, $795-$4017) and relative out-of-pocket expenses (3.93% vs 3.07%; difference, 0.86%; 95% CI, 0.06%-1.66%) were higher for patients with HNC than for patients with other cancers. Among patients with HNC, median expenses were lower for Asian individuals compared with white individuals ($5359 vs $10 078; difference, $4719; 95% CI, $1481-$7956]), Westerners ($8094) and Midwesterners ($5656) compared with Northwesterners ($10 549), and those with better health status ($16 990 for those with poor health vs $6714 for those with excellent health). Higher relative out-of-pocket expenses were associated with unemployment (5.13% for employed patients vs 2.35% for unemployed patients; difference, 2.78%; 95% CI, 0.6%-4.95%), public insurance (5.35% for those with public insurance vs 2.87% for those with private insurance; difference, 2.48%; 95% CI, -0.6% to 5.55%), poverty (13.07% for poor patients vs 2.06% for high-income patients), and lower health status (10.2% for those with poor health vs 1.58% for those with excellent health).
Conclusions and Relevance: According to this study, HNC adds a substantial, additional burden to an already financially strained population in the form of higher total and relative expenses. The financial strain on individuals, assessed as relative out-of-pocket expenses, appears to be driven more by income than by health factors, and health insurance does not appear to be protective.

Add‐on probiotics in patients with persistent allergic rhinitis: A randomized crossover clinical trial
Objectives
Current medications for allergic rhinitis (AR) may have undesirable side effects that could affect quality of life (QoL). Probiotics could be an alternative in these patients. The aim of this study was to assess the impact of add‐on probiotics on symptoms and QoL of patients.
Methods
In this randomized crossover clinical trial, patients with persistent AR were included. Each subject received budesonide with probiotic supplements (BP) or budesonide with placebo for 8 weeks (B), then vice versa for a further 8 weeks. There was an 8‐week washout. The primary outcome was the change of the Short Form 36‐Item Health Survey (SF‐36) score. The secondary outcomes were assessed by the Sinonasal Outcome Test‐22 (SNOT‐22) and the Control of Allergic Rhinitis and Asthma Test (CARAT) questionnaires.
Results
A total of 152 subjects (30.1 ± 7.6 years) completed the study. The SF‐36 score in both groups showed improvement compared with baseline values. Treatment BP was more effective than that of B. The Cohen's d and the number needed to treat for Physical Component Scales of SF‐36 were 0.40 and 10.77, respectively. These values for Mental Component Scales were 0.33 and 12.61, respectively. Also, treatment BP showed more reduction in the score of SNOT‐22 and CARAT.
Conclusion
This study showed that the addition of probiotics to budesonide significantly improved QoL in persistent AR patients. However, the clinical situation of these patients may be not very representative of AR patients in general population. Further studies are recommended.

3D‐printed, externally‐implanted, bioresorbable airway splints for severe tracheobronchomalacia
Objectives/Hypothesis
To report the clinical safety and efficacy of three‐dimensional (3D)–printed, patient‐specific, bioresorbable airway splints in a cohort of critically ill children with severe tracheobronchomalacia.
Study Design
Case series.
Methods
From 2012 to 2018, 15 subjects received 29 splints on their trachea, right and/or left mainstem bronchi. The median age at implantation was 8 months (range, 3–25 months). Nine children were female. Five subjects had a history of extracorporeal membrane oxygenation (ECMO), and 11 required continuous sedation, six of whom required paralytics to maintain adequate ventilation. Thirteen were chronically hospitalized, unable to be discharged, and seven were hospitalized their entire lives. At the time of splint implantation, one subject required ECMO, one required positive airway pressure, and 13 subjects were tracheostomy and ventilator dependent, requiring a median positive end‐expiratory pressure (PEEP) of 14 cm H2O (range, 6–20 cm H20). Outcomes collected included level of respiratory support, disposition, and splint‐related complications.
Results
At the time of discharge from our institution, at a median of 28 days postimplantation (range, 10–56 days), the subject on ECMO was weaned from extracorporeal support, and the subjects who were ventilated via tracheostomy had a median change in PEEP (discharge–baseline) of −2.5 cm H2O (range, −15 to 2 cm H2O, P = .022). At median follow‐up of 8.5 months (range, 0.3–77 months), all but one of the 12 surviving subjects lives at home. Of the 11 survivors who were tracheostomy dependent preoperatively, one is decannulated, one uses a speaking valve, six use a ventilator exclusively at night, and three remain ventilator dependent.
Conclusions
This case series demonstrates the initial clinical efficacy of the 3D‐printed bioresorbable airway splint device in a cohort of critically ill children with severe tracheobronchomalacia.
