Combat zone exposure and respiratory tract disease

The impact of deployment to combat zones on the respiratory and sinonasal health of U.S. soldiers is an emerging public health concern. Retrospective studies have shown a correlation between deployment and development of post-deployment pathology, particularly of the aerodigestive system. Respiratory disease, including sinusitis, allergic rhinitis, and asthma, are commonly reported in soldiers deployed to the Middle East and Southwest Asia.Current literature pertaining to combat zone exposure and development of respiratory disease was retrieved using PubMed,\ua0Embase, Web of Science, and Google Scholar.Several types of combat zone exposures exist that may play an influential role in the development of upper and lower respiratory tract diseases. Exposures including foreign dusts, harsh environments, particulate size, and close living quarters may play a causative role. The effect of combat zone exposures has been better examined for lower respiratory tract diseases; however, with the theory of the unified airway, the upper respiratory tract may also be involved. There is evidence that the upper respiratory tract is susceptible, with an increased risk for development of sinusitis and sinonasal disease; however, the quality of evidence of the present literature is generally low.More research is necessary to determine a pathophysiologic mechanism between combat zone exposure and the development of sinonasal disease. Practicing otolaryngologists should be aware of the possibility of combat zone exposures that could contribute to rhinologic symptomatology

Layperson perception of reflux-related symptoms

OBJECTIVE: To assess for differences of intended meaning in the description of reflux-related symptoms among otolaryngology patients and clinicians. STUDY DESIGN: Cross-sectional survey-based study. SETTING: Five tertiary, academic otolaryngology practices. METHODS: Between June 2020 and July 2022, a questionnaire consisting of 20 common descriptors of reflux-related symptoms within four domains (throat-, chest-, stomach-, and sensory-related symptoms) was completed by patients. Attending otolaryngologists at five academic medical centers then completed the same survey. The primary outcome was to assess differences in patient and clinician perceptions of reflux-related symptoms. Differences based on geographic location was a secondary outcome. RESULTS: A total of 324 patients and 27 otolaryngologists participated. Patients selected a median of six terms compared with 10.5 for otolaryngologists ( CONCLUSION: There are differences between otolaryngologists and their patients in the interpretation of the symptoms of reflux. Patients tended to have a narrower interpretation of reflux with symptoms primarily limited to classic stomach-related symptoms, while clinicians tended to have a broader definition of reflux that included extra-esophageal manifestations of disease. This has important counseling implications for the clinician, as patients presenting with reflux symptoms may not comprehend the relationship of those symptoms to reflux disease

Interrater agreement of nasal endoscopy in patients with a prior history of endoscopic sinus surgery

Nasal endoscopy is an important part of the clinical evaluation of patients with chronic rhinosinusitis. However, its objectivity and inter-rater agreement have not been well studied, especially in patients who have previously had sinus surgery

The Infratemporal Fossa Sign: Pilot Study of a Potential Clue to Eustachian Salpingitis

Aural discomfort may be the result of obstructive eustachian tube (ET) dysfunction, temporomandibular joint dysfunction, or other causes. The infratemporal fossa (ITF) sign, in which a patient points to a characteristic location below the auricle, is proposed as an indicator of nonobstructive eustachian salpingitis. A preliminary study included patients with a complaint of aural discomfort who were prompted to localize symptoms using a single finger. Group 1 localized by using the ITF sign; group 2 localized deep within the external ear canal (suggesting ET dysfunction); and group 3 localized to the preauricular region (suggesting temporomandibular joint dysfunction). Findings of ET inflammation recorded during nasal endoscopy were greater in groups 1 and 2. Tympanometry and otoscopy were uniformly abnormal for group 2 and uniformly normal for groups 1 and 3. The ITF sign may help to identify eustachian salpingitis as a phenotype of ET disease characterized by symptomatic inflammation without abnormal middle ear pressure

The condemned sinus: natural disease or surgical sequela?

Background: Unilateral, mucopurulent drainage from an isolated paranasal sinus may be encountered in patients with a history of surgery for the treatment of chronic rhinosinusitis (CRS). Static mucus is visualized on nasal endoscopy within the sinus lumen but without significant disease in the adjacent sinuses. The reasons for this phenomenon are unknown although an iatrogenic cause is proposed.Methods: A case series was prospectively compiled from consecutive patients presenting for evaluation of CRS at a tertiary rhinology practice during a 16-month period. Computerized tomography and nasal endoscopy were performed, and endoscopically directed aerobic and anaerobic bacterial cultures were obtained. Osteitis scores were recorded for diseased and nondiseased sides.Results: Twenty-three of 113 patients (20.4%) had evidence of chronic unilateral drainage from either a maxillary (21) or sphenoid (2) sinus. Mean osteitis scores were higher for the diseased side (P < 0.01). A nonendoscopic transantral approach was reported in 57.1% of cases with chronic maxillary disease, with 52.2% occurring more than 10 years earlier. The most common bacterial isolate was Pseudomonas aeruginosa (6 cases, 26.1%), followed by methicillin-resistant Staphylococcus aureus (5 cases, 21.7%). Six cases (26.1%) were polymicrobial, and 6 (26.1%) were culture-negative. Tobacco use was reported in 8 (34.8%) cases, and chronic obstructive pulmonary disease was present in 6 (26.1%) cases.Conclusion: The condemned sinus is a distinct entity that may represent a sequela of previous non-mucosal-sparing surgery. An association with hyperostosis is observed. Mucopurulent drainage is characterized by polymicrobial infection comparable to that found in diffuse CRS

Direct-To-Consumer Advertising of Over-the-Counter Sinonasal Remedies: A History of Mixed Messages

Sinus, cold, and allergy remedies comprise the most widely used sector of the over-the-counter (OTC) drug market. Direct-to-consumer advertising (DTCA) of pharmaceutical products has increased over the past 30 years, including the promotion of OTC drugs. The influence of DTCA on OTC sinonasal remedies comprises several positive and negative effects. Favorable aspects of this influence include empowerment and promotion of autonomy among patients, avoidance of low-value clinical encounters, self-directed education, and decreased healthcare expenditures. This is balanced by potential concerns, including the lack of rigorous regulation of OTC drugs, the burden of self-diagnosis, the risk of unsupervised use resulting in adverse effects or drug interactions, and redistribution of pharmacy costs to the consumer. Despite the proliferation of product options and consumer-directed information, healthcare utilization and cost of treating sinonasal disease remains high. Moreover, the availability of OTC sinonasal remedies and exposure to DTCA has had mixed effects without apparent overall benefit to patient and consumer health. Laryngoscope, 201

Contralateral Orbital Mucocele as a Complication of Unilateral Nasal Polyposis

Mucocele is a rare complication of chronic rhinosinusitis that typically presents with delayed diagnosis and results in local erosion. We present the case of a symptomatic orbital mucocele arising from contralateral sinus disease that crossed the midline upon diversion by the effect of prior trauma. Effective treatment was provided by combined endoscopic surgery and external drainage

Corticosteroid utilization among otolaryngologists for the treatment of acute upper respiratory tract infections.

PURPOSE: To determine the effects of knowledge and practice variations on prescribing patterns of systemic corticosteroids (SC) for acute upper respiratory tract infections (URTI). MATERIALS AND METHODS: A cross-sectional evaluation of practicing otolaryngologists in the United States through the use of a 16-question Knowledge, Attitude, and Practice survey. The survey was self-administered through email delivery to practicing members of the American Academy of Otolaryngology-Head and Neck Surgery. RESULTS: Of 349 respondents, the majority were attending physicians in private practice and used SC 25% to 50% of the time. There was a higher rate of SC use by clinicians in the Southeast United States (adjusted odds ratio [aOR], 2.10; 95% confidence intervals [95% CI], 1.18-3.72) and by those in private practice (aOR, 2.67; 95% CI, 1.63-4.37). Levels of SC knowledge did not vary across respondents; however, knowledge was associated with increased use of SC. Only 62.8% of respondents answered all 4 Knowledge questions correctly and this was associated with a 3.5-fold decrease in SC use (aOR, 0.29; 95% CI, 0.19-0.44). Attitudes toward SC use reflected prescribing practices and were also linked to levels of knowledge, as respondents with less knowledge were more likely to have a favorable outlook toward use of SC. CONCLUSION: Use of SC for treatment of acute URTI is associated with clinician demographics and knowledge. Otolaryngologists are more likely to use SC for acute URTI in the Southeast United States and in private practice. Knowledge and provider education are key factors in prescribing patterns

Management of rhinitis medicamentosa: a systematic review

Objective: Rhinitis medicamentosa (RM) is a common condition resulting from overuse of topical nasal decongestants. Despite the prevalence in otolaryngologic practice, a clear treatment protocol has not been established. Our objective was to review the current published literature pertaining to the treatment of RM with the possibility of finding data that support one treatment over another. Data Sources: PubMed, Embase, Cochrane, and Web of Science databases were examined for patients diagnosed with RM resulting from chronic use of topical nasal decongestants. Review Methods: The PRISMA standard (Preferred Reporting Items for Systematic Reviews and Meta-analyses) was utilized to identify English-language studies reporting treatment of patients with the primary diagnosis of RM after chronic use of a topical decongestant. Outcome measures of interest included patient-reported symptom relief and objective parameters. MINORS criteria (methodological index for nonrandomized studies) were used to assess the quality of articles. Results: A total of 350 articles were identified, 9 of which met final inclusion criteria for qualitative analysis. Outcomes defined in each publication were highly varied and relied on several unstandardized measures. The most commonly reported treatment option was topical nasal steroids, although overall there was limited evidence on which to base treatment recommendation. Conclusions: There is not adequate evidence to develop a standardized treatment protocol for RM. The development of a uniform questionnaire, standard outcomes to be measured, and a method of assessing such outcomes is necessary. Prospective randomized controlled studies are warranted to determine the optimal treatment regimen following diagnosis of RM

Polypoid change of the middle turbinate and paranasal sinus polyposis are distinct entities

Objectives: Polypoid change of the middle turbinate (PCMT) is a finding on intranasal examination whose significance is not well understood. We present a comparison of the clinical characteristics of PCMT with paranasal sinus polyposis (PSP), a common condition with potentially similar appearance. Study Design: Parallel case series. Setting: Tertiary rhinology clinic. Subjects and Methods: Data were prospectively compiled from consecutive patients during a 12-month period with either PSP arising from the middle meatus or PCMT limited to the middle turbinate as identified on nasal endoscopy. Recorded data included comorbidities, the 22-item Sinonasal Outcome Test (SNOT-22), Nasal Obstruction Symptom Evaluation (NOSE), Lund-Mackay score from computed tomography (CT) imaging, and total eosinophil levels. Results: Of 593 patients, 23 (3.9%) had PCMT and 44 (7.4%) had PSP. The PSP group was predominantly male (75% vs 52%,
