Usefulness of pepsin saliva measurement for the detection of primary burning mouth syndrome related to reflux.

OBJECTIVES: To study the diagnostic value of salivary pepsin tests for detecting laryngopharyngeal reflux (LPR) in patients with primary burning mouth syndrome (BMS). METHODS: Patients with BMS and asymptomatic individuals were consecutively recruited from September 2018 to June 2023. Patients underwent hypopharyngeal-esophageal impedance pH-monitoring (HEMII-pH) and saliva collections to measure pepsin. Stomatology evaluation was carried out to exclude other causes of BMS. Oral, pharyngeal and laryngeal signs and symptoms were evaluated with Reflux Sign Assessment (RSA) and Reflux Symptom Score (RSS). Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values of pepsin test were calculated considering the highest values of pepsin tests at ≥ 16, ≥ 36, and ≥ 100 ng/mL cutoffs. Receiver operating characteristic curve (ROC) was evaluated. RESULTS: Forty-nine patients with both BMS and LPR at the HEMII-pH and 21 asymptomatic individuals were recruited. Pepsin test was 83.7%, 79.6%, and 71.4% sensitive at cutoffs ≥ 16, ≥ 36, and ≥ 100 ng/mL, respectively. The ROC analysis reported that a threshold of ≥ 21.5 ng/mL was associated with sensitivity, specificity, PPV and NPV of 81.6%, 81.0%, 90.1% and 65.4%, respectively. The severity score of burning mouth symptom was significantly associated with the saliva pepsin concentration (rs = 0.263; p = 0.029) and the oral RSA (rs = 0.474; p = 0.007). CONCLUSION: Pepsin test is a valuable diagnostic approach for detecting LPR in patients with BMS. Patients with high level of saliva pepsin reported more severe burning mouth symptoms. Future studies are needed to confirm the role of LPR in the primary BMS.

International palate surgery questionnaire.

BACKGROUND: This international study aimed at determining current routine palate surgeries and surgical methods adopted by otolaryngologists who practice surgical management of obstructive sleep apnea (OSA). METHODS: An international online survey was developed with the collaboration of the YO-IFOS (Young Otolaryngologists-International Federation of Otorhinolaryngological Societies) to assess the current routines in palatal procedures. The surgeons were asked 33 multiple-choice questions. RESULTS: A total of 141 sleep surgeons answered the questionnaire, of whom 27% were from Africa, 30% from Asia, 24% from Centre-South America, and 19% from Europe. According to otolaryngology surgical specialties, 51% were sleep surgeons, 31% general ENTs, 8% Rhinologists, 7% Head & Neck surgeons, 2% otologists, and 1% maxillofacial surgeons. Of the 141 respondents, 51% answered they were sleep specialists, whereas 49% were non-sleep specialists. According to specific medical degree, 38% were specialists, 33% were consultants, 25% were professors, and 4% were residents or trainees. CONCLUSION: This study gives an overview of the current surgical practice in OSA management in otolaryngology in different countries.

Saliva pepsin measurements in the detection of gastroesophageal reflux disease in laryngopharyngeal reflux patients: a cohort study.

OBJECTIVE: To study the diagnostic value of salivary pepsin measurement (Peptest) for detecting gastroesophageal reflux disease (GERD) in laryngopharyngeal reflux (LPR) patients. METHODS: Patients with reflux symptoms were consecutively recruited from January 2020 to November 2022. Patients benefited from hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH), fasting and bedtime saliva collections to measure pepsin. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were evaluated for GERD and LPR patients considering the highest values of pepsin tests at ≥ 16, ≥ 75, and ≥ 216 ng/mL cutoffs. The relationship between HEMII-pH, endoscopic and clinical findings, and pepsin measurements was studied. RESULTS: Saliva was collected in 109 LPR patients and 30 individuals with both LPR and GERD. The total number of pharyngeal reflux events was significantly higher in GERD-LPR patients compared with LPR patients (p = 0.008). The mean fasting and bedtime pepsin saliva concentrations were similar between groups. The sensitivity of Peptest in LPR patients was 30.5%, 70.2%, and 84.0% at cutoffs ≥ 16, ≥ 75 and ≥ 216 ng/mL. In GERD-LPR group, Peptest was 80.0%, 70.0%, and 30.0% sensitive. At cutoff 16 ng/mL, Peptest reported PPV of 20.7% and 94.8% in LPR-GERD and LPR groups, respectively. NPV were 73.9% and 8.7% in GERD-LPR and LPR groups, respectively. The consistency analysis between Peptest and HEMII-pH was not significant. Peptest was significantly associated with the number of acid pharyngeal reflux events (rs = 0.182; p = 0.032). CONCLUSION: Pepsin saliva measurements appear to be not a reliable diagnostic tool for the detection of GERD in LPR patients. Future studies are needed to determine the place of Peptest in laryngopharyngeal reflux and gastroesophageal reflux diseases.

Feasibility and safety of THRIVE in transoral laser microsurgery.

OBJECTIVE: Transnasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) presents obvious advantage in laryngeal surgery and Transoral Laser Microsurgery (TLM). Airway fire represents a rare complication of TLM and may be the most important limitation in the use of THRIVE. The objective was to evaluate the different operating conditions of the TLM with THRIVE with regard to fire risk. EXPERIMENT: In this report, we assessed the risk of fire by varying the Fraction of Inspired Oxygen (FiO2), the Laser Energy, and the placement of endolaryngeal surgical and ventilatory equipment in a porcine model for TLM. RESULTS: Fire, sparks and smoke were reported. No combustion occurred with THRIVE in the absence of an endolaryngeal material. Fire occurred systematically while delivering between 3 and 5 W Carbon dioxide (CO2) Laser direct shot on a dry laryngeal cotton. Conclusion THRIVE-TLM should never be performed using a dry cotton or a plastic endolaryngeal material.

Efficacy of auriculotherapy in the control of pain, edema, and trismus following surgical extraction of the lower third molars: a split-mouth, randomized, placebo-controlled, and triple-blind study.

BACKGROUND: The aim of this split-mouth, randomized, placebo-controlled, and triple-blind study was to evaluate whether auriculotherapy had any effect on the post-operative course after the extraction of third molars in terms of the control of pain, edema, and trismus. MATERIALS AND METHODS: The study included 42 patients (84 teeth) who had undergone a surgical extraction of the lower third molars. In each patient, the two extractions were randomly assigned to two study groups. In the therapy group, the patients underwent auriculotherapy with vaccaria seeds applied with patches in 6 ear points. In the control group, the patches were applied, without seeds, to the same ear points. After the extraction, the patients were asked to stimulate the ear points three times a day and whenever they felt pain. The patients were asked to keep a diary in which they assessed their pain by means of the Visual Analog Scale (VAS) for 8 days. Edema and trismus were assessed 1, 2, 3, and 8 days after surgery. RESULTS: The differences between the two groups were statistically significant at the 12-h control (auriculotherapy group (AG) VAS 5.5 [IQR 4.25-6.75], placebo group (PG) VAS 6 [IQR 5-8], p = 0.040), after 24 h (AG VAS 5 [IQR 4-6], PG VAS 6 [IQR 4.25-7], p = 0.024), after 2 days (AG VAS 4 [IQR 3-5], PG VAS 4.5 [IQR 4-6], p = 0.044), and after 3 days (AG VAS 3 [IQR 0-5], PG VAS 4 [IQR 3-5], p = 0.024). Throughout the observation period, the AG took a significantly lower number of painkillers than the PG (AG 6 [IQR 4.25-7]; PG 8 [IQR 8-9], p < 0.001). There were no significant differences in the levels of edema and trismus between the two groups throughout the observation period. CONCLUSIONS: On the basis of the results of the present study, auriculotherapy can be considered as a cost-effective adjuvant pain reliever treatment in patients undergoing an extraction of the lower third molars.

Full-arch rehabilitation of severely atrophic maxilla with additively manufactured custom-made subperiosteal implants: A multicenter retrospective study.

The aim of this retrospective study was to analyze a series of patients who underwent full-arch rehabilitation of the atrophic maxilla using additively manufactured subperiosteal implants, between August 2018 and January 2023, at the Universities of Sassari and Poznan. In total, 36 patients and 72 implants were included, with no implants lost during follow-up, and a success rate of 90.3%. Seven (9.7%) of the implants showed class 1 exposure. Bleeding on probing was detected in 10.4% of the abutments at 6 months, 7.9% at 1 year, 10% at 2 years, 7% at 3 years, and 11.4% at 4 years. No significant bone resorption under the abutments was detected during the whole observation period. Based on the findings from this study, additively manufactured subperiosteal implants could represent a safe and reliable technique for full-arch rehabilitation in patients with severe maxillary atrophy.

Digestive Biomarkers of Laryngopharyngeal Reflux: A Preliminary Prospective Controlled Study.

OBJECTIVE: To investigate the digestive enzymes and biomarkers in the saliva of patients with laryngopharyngeal reflux (LPR) and asymptomatic individuals. STUDY DESIGN: Prospective controlled study. SETTING: Multicenter study. METHODS: Patients with LPR at the hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH) and asymptomatic individuals were consecutively recruited from January 2020 to April 2023 from 2 University Hospitals. The saliva of patients (off PPIs) and asymptomatic individuals was collected to measure pH, elastase, bile salts, cholesterol, gastric, and pancreatic lipases. Anxiety, symptoms, and findings were studied through perceived stress scale (PSS), reflux symptom score (RSS), and reflux sign assessment (RSA). RESULTS: Sixty-seven LPR patients and 57 asymptomatic individuals completed the evaluations. LPR patients reported higher PSS, RSS, and RSA than asymptomatic individuals. The mean saliva pH was more alkaline in LPR patients (7.23: 95% confidence interval [CI]: 7.08, 7.38) compared to controls (6.13; 95% CI: 5.95, 6.31; P = .001). The mean concentration of elastase was higher in patients (51.65 µg/mL; 95% CI: 44.47, 58.83 µg/mL) versus asymptomatic individuals (25.18 µg/mL; 95% CI: 21.64, 28.72 µg/mL; P = .001). The saliva cholesterol reported higher concentration in healthy individuals (3.43 mg/dL; 95% CI: 3.21, 3.65 mg/dL) compared to patients (1.16 mg/dL; 95% CI: 1.05, 1.27 mg/dL; P = .001). The saliva pH, and elastase concentration were significantly associated with the baseline RSS, while saliva cholesterol was negatively associated with the severity of RSS and RSA. CONCLUSION: Cholesterol, bile salts, and elastase are biomarkers of LPR and should be considered to develop future non-invasive saliva device for the detection of LPR.

Association between oropharyngeal ph-monitoring, pepsin saliva concentration and degree of apnea-hypopnea index of obstructive sleep apnea.

OBJECTIVE: To investigate the association between obstructive sleep apnea (OSA) and laryngopharyngeal reflux (LPR) through oropharyngeal pH-monitoring and pepsin saliva measurements. DESIGN: Prospective uncontrolled study. METHODS: Patients with sleep disturbances and reflux symptoms underwent polysomnography, 24-h oropharyngeal pH-monitoring and saliva pepsin collections. The prevalence of LPR was investigated in OSA patients according to oropharyngeal pH-monitoring and pepsin measurements. A correlation analysis was performed between pH-monitoring findings, pepsin saliva levels, reflux symptom score-12 (RSS-12), reflux sign assessment (RSA), Apnea-Hypopnea Index (AHI), Epworth Sleepiness Scale, Pichot and arousal findings. RESULTS: Thirty-seven patients completed the evaluations. LPR was detected in 34/37 (92%) and 29/34 (85%) patients at the oropharyngeal-pH monitoring and pepsin test, respectively. OSA was detected in 30 patients (81%). Among them, LPR was detected in 28/30 (93%) cases. Pharyngeal reflux events mainly occurred nighttime/supine in OSA patients. Both Ryan score and supine reflux time at pH < 6.5 were significantly associated with BMI and the RSA sub- and total scores (p < 0.02). Tongue-base hypertrophy score was positively associated with the number of micro-arousals (p = 0.027); the supine percent of pH < 6.5 (p = 0.030); morning (p = 0.030) and bedtime pepsin saliva measurements (p = 0.037). The bedtime pepsin saliva level was significantly associated with Ryan Score (p = 0.047); AHI (p = 0.017) and the sleep saturation < 90% time (p = 0.040). The saliva level of the morning pepsin was associated with a shortest paradoxical sleep phase (p = 0.013). CONCLUSION: OSA patients may have high prevalence of pharyngeal reflux events at the oropharyngeal pH-monitoring and high pepsin saliva measurements. Oropharyngeal pH-monitoring should be useful for the correlation between reflux and sleep findings in OSA patients. Future large cohort controlled studies are needed to determine the prevalence of LPR in OSA and healthy individuals.

Variability and accuracy of multiple saliva pepsin measurements in laryngopharyngeal reflux patients.

OBJECTIVE: To study the variability and diagnostic value of multiple salivary pepsin measurements in the detection of laryngopharyngeal reflux (LPR). METHODS: Patients with LPR symptoms were consecutively recruited from December 2019 to Augustus 2022. Twenty-one asymptomatic individuals completed the study. The diagnostic was confirmed with hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH). Patients collected three saliva samples during the 24-h testing period. Symptoms and findings were studied with reflux symptom score-12 and reflux sign assessment. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values of pepsin measurements were calculated considering morning, post-lunch and post-dinner samples. The consistency and relationship between HEMII-pH, pepsin measurements, and clinical features were investigated. RESULTS: Morning, post-lunch and post-dinner saliva pepsin concentrations were measured in 42 patients. Pepsin measurements were 64.9%, 59.5%, and 59.0% sensitive for morning, post-lunch and post-dinner collections at cutoff ≥ 16 ng/mL. Considering the highest concentration of the three pepsin saliva collections, the accuracy, sensitivity, specificity and PPV were 70.5%, 73.0%; 66.7% and 78.9%, respectively. Morning pepsin measurements reported higher consistency, sensitivity, and specificity than post-dinner and post-lunch pepsin measurements. CONCLUSION: The collection of several saliva pepsin samples improves the detection rate of LPR. In case of high clinical LPR suspicion and negative pepsin test, a HEMII-pH study could provide further diagnostic information.

Marginal versus Segmental Mandibulectomy in the Treatment of Oral Cavity Cancer: A Systematic Review and Meta-analysis.

Introduction Oral cavity squamous cell carcinoma (OCSCC) is the most common malignancy in the oral cavity. Two types of mandibular resections have been described: the segmental mandibulectomy and the marginal mandibulectomy. Both may have a different impact over the quality of life, oncological prognosis, and functional or aesthetic result. Objectives The aim of this study was to systematically explore the literature to determine the survival outcomes and disease control rates in patients who underwent segmental or marginal mandibulectomy for OCSCC with histological evidence of cortical and medullary bone invasion. Data Synthesis This review involved a systematic search of the electronic databases MEDLINE/PUBMED, Google Scholar, Ovid Medline, Embase, and Scopus including articles from 1985 to 2019. Fifteen articles were included for qualitative analysis and 11 articles were considered for meta-analysis calculations. All of them correspond to retrospective cohort studies. Conclusion This systematic review reveals the low-level evidence regarding the impact over local control or survival according to the type of mandibulectomy. Our results need to be considered with precaution according to the limited evidence available. We just found difference regarding the 5-year disease-free survival, and a tendency in favor of segmental mandibulectomy was confirmed when medullary invasion was evident.

Are YouTube Videos a Useful and Reliable Source of Information for Patients with Temporomandibular Joint Disorders?

Counseling is considered a first-line conservative therapy with respect to temporomandibular joint disorders (TMJD). Nowadays, 50 to 80% of patients acquire health information from the internet before turning to professionals. The purpose of this study has been to investigate the quality of information about TMJD that patients can obtain from YouTube. A YouTube.com search was conducted using the terms "temporomandibular joint disorder"; "limited movement of the mandible"; and "mandibular joint pain". The videos identified were assessed independently by two panels of three professional and lay reviewers with HONcode, modified DISCERN (MD) and the global quality scale (GQS). A total of 106 videos were included. The professional reviewers reported a mean HONcode score of 4.148 ± 1.314 and a mean MD score of 2.519 ± 1.267, testifying to a modest general quality of the videos. The mean GQS score was 2.987 ± 1.012 for the professional and 3.469 ± 0.891 for the lay reviewers (p < 0.001). The correlations between the ratings were significant between the reviewers within the same group but not between the two groups. The presence of animations significantly influenced the GQS score expressed by the lay reviewers (p = 0.011) but not that of the professionals (p = 0.640). The quality of the information on TMJD on YouTube is generally of poor quality. Healthcare systems and professionals should be prepared to correct misinformation and build trusting relationships with patients which are based on quality counseling. Similarly, academic institutions should produce quality content that leads patients with TMJD toward a correct diagnostic-therapeutic process.

Comprehensive management of paranasal sinus fungus balls: A Young-IFOS consensus statement.

BACKGROUND: Paranasal sinus fungus balls (PSFB) are a common form of surgically treatable, noninvasive mycosis. To date, no guidelines have standardized PSFB treatment or management of difficult cases (eg, immunocompromised or fragile patients). The clinical consensus statement presented herein aims to provide a comprehensive management guide to PSFB based on current evidence. METHODS: A multidisciplinary, international panel of 19 specialists judged statements in 3 rounds of a modified Delphi method survey. Statements encompassed the following PSFB management issues: definition, diagnostic workup; treatment indications and modalities; and follow-up. Otolaryngologists, maxillofacial surgeons, infectious disease specialists, and transplant physicians were considered the target audience. RESULTS: Among the 23 statements, 7 reached strong consensus and 16 reached consensus. Consensus was reached on the definition, diagnosis, and treatment modalities for PSFB. Postoperative follow-up modalities and scenarios with bacterial superinfection were the most debated issues. CONCLUSION: Until further data are available, these points provide a framework for the management of PSFB. Moreover, PSFB should be considered a noninvasive mycosis that is not necessarily symptomatic or related to odontogenic conditions. Although diagnosis may be incidental, endoscopy and single imaging (computed tomography or magnetic resonance imaging, with distinctive features) are required for diagnosis, whereas contrast medium would allow for differential diagnosis. Although treatment of PSFB should be considered mandatory before sinus augmentation and is recommended for symptomatic patients, immunosuppressed patients, or patients with planned immunosuppression, watchful waiting could be considered for asymptomatic patients with chronic rhinosinusitis who are provided with appropriate advice and assessment.

The Recumbent Position Affects Nasal Resistance: A Systematic Review and Meta-Analysis.

OBJECTIVE: Nasal diseases are among the main motives for the early discontinuation of continuous positive airway pressure therapy and for long-term therapeutic compliance with mandibular advancement device. Although our clinical experience leads us to the belief that recumbency impacts nasal airflow in some patient populations, there is no consensus regarding the magnitude of this effect and the specific group of patients who are the most affected by this condition. In this study, we conducted a meta-analysis to assess the effect of the recumbent position on nasal resistance and nasal airflow. REVIEW METHODS: PubMed (Medline), Cochrane Library, EMBASE, Scopus, and SciELO databases were checked for relevant studies by two members of the YO-IFOS study group. The two authors extracted the data. The main outcome was expressed as the difference between nasal resistance and nasal airflow before and after recumbency. RESULTS: Nine studies with a total population of 291 individuals were included in the meta-analysis for nasal resistance after recumbency. We found a statistically significant difference in nasal airway resistance of -0.18 Pa sec/cm3 as compared to before and after recumbency through rhinomanometry (RMM) analysis. A subgroup analysis revealed a variation of -0.20 Pa sec/cm3 for patients with snoring or sleep apnea and - 0.10 Pa sec/cm3 for healthy individuals. Regarding nasal airflow measured with RMM, three studies (n = 32) in asymptomatic controls revealed a statistically significant difference of 47.33 ml/sec. CONCLUSIONS: Recumbency increases nasal resistance and diminishes nasal airflow. This finding is of utmost importance in snorers and sleep apnea patients. Laryngoscope, 132:6-16, 2022.

Relationship between short lingual frenulum and malocclusion. A multicentre study.

OBJECTIVE: Ankyloglossia is characterized by an abnormally short lingual frenulum, which impairs tongue movement. Ankyloglossia has been related to craniofacial growth disturbances and dental malocclusion. But even though there is a clear biological plausibility for this hypothesis, available evidence is scarce. METHODS: A case-control design was followed. Patients between 4 and 14 years old were routinely screened for short lingual frenulum and recruited from the pediatric Otolaryngology consultation of 3 Spanish tertiary referral hospitals. Lingual frenulum was assessed with the Marchesan system. A cohort of cases with short lingual frenulum and a cohort of healthy controls matched for sex and age were included. Both cases and controls had pictures of occlusion. Occlusion was evaluated by an expert in orthodontics, blinded for the frenulum assessment. RESULTS: A total of 100 participants were included, 70 males and 30 females. The proportion of malocclusion in the short lingual frenulum group was 48%, while it was 24% in the normal frenulum group. The odds ratio of malocclusion for the short lingual frenulum patients was 2.92 (CI 95% 1.15-7.56). The difference was statistically significant (p=.012). This difference was significant for patients with class III occlusion (p=.029). There was no difference for patients with class II (p=.317). CONCLUSIONS: This work supports the hypothesis that relates class III malocclusion with a short lingual frenulum.

Radiographic protrusion of dental implants in the maxillary sinus and nasal fossae: A multidisciplinary consensus utilising the modified Delphi method.

The aim of the present study was to generate an international and multidisciplinary consensus on the clinical management of implant protrusion into the maxillary sinuses and nasal fossae. A total of 31 experts participated, 23 of whom were experts in implantology (periodontologists, maxillofacial surgeons and implantologists), 6 were otolaryngologists and 2 were radiologists. All the participants were informed of the current scientific knowledge on the topic based on a systematic search of the literature. A list of statements was created and divided into three surveys: one for all participants, one for implant providers and radiologists and one for otolaryngologists and radiologists. A consensus was reached on 15 out of 17 statements. According to the participants, osseointegrated implants protruding radiographically into the maxillary sinus or nasal fossae require as much monitoring and maintenance as implants fully covered by bone. In the event of symptoms of sinusitis, collaboration between implant providers and otolaryngologists is required. Implant removal should be considered only after pharmacological and surgical management of sinusitis have failed.

Atypical Clinical Presentation of Laryngopharyngeal Reflux: A 5-Year Case Series.

BACKGROUND: Laryngopharyngeal reflux (LPR) is a common disease in otolaryngology characterized by an inflammatory reaction of the mucosa of the upper aerodigestive tract caused by digestive refluxate enzymes. LPR has been identified as the etiological or favoring factor of laryngeal, oral, sinonasal, or otological diseases. In this case series, we reported the atypical clinical presentation of LPR in patients presenting in our clinic with reflux. METHODS: A retrospective medical chart review of 351 patients with LPR treated in the European Reflux Clinic in Brussels, Poitiers and Paris was performed. In order to be included, patients had to report an atypical clinical presentation of LPR, consisting of symptoms or findings that are not described in the reflux symptom score and reflux sign assessment. The LPR diagnosis was confirmed with a 24 h hypopharyngeal-esophageal impedance pH study, and patients were treated with a combination of diet, proton pump inhibitors, and alginates. The atypical symptoms or findings had to be resolved from pre- to posttreatment. RESULTS: From 2017 to 2021, 21 patients with atypical LPR were treated in our center. The clinical presentation consisted of recurrent aphthosis or burning mouth (N = 9), recurrent burps and abdominal disorders (N = 2), posterior nasal obstruction (N = 2), recurrent acute suppurative otitis media (N = 2), severe vocal fold dysplasia (N = 2), and recurrent acute rhinopharyngitis (N = 1), tearing (N = 1), aspirations (N = 1), or tracheobronchitis (N = 1). Abnormal upper aerodigestive tract reflux events were identified in all of these patients. Atypical clinical findings resolved and did not recur after an adequate antireflux treatment. CONCLUSION: LPR may present with various clinical presentations, including mouth, eye, tracheobronchial, nasal, or laryngeal findings, which may all regress with adequate treatment. Future studies are needed to better specify the relationship between LPR and these atypical findings through analyses identifying gastroduodenal enzymes in the inflamed tissue.

Contribution of Interventional Radiologist in the Management of Pseudoaneurysm and Neck Hemorrhages in COVID-19 patients.

Patients with severe coronavirus disease 2019 (COVID-19) may have endothelial inflammation, pseudoaneurysm, and an increasing risk of bleeding, especially during surgical procedures. In this article, we reported 2 cases of COVID-19 patients with neck vascular lesions. The first patient had pseudoaneurysm of the cricothyroid artery, which was treated by percutaneous glue injection through ultrasonography guidance. The second patient presented lateral neck hematoma in front of the left superior thyroid artery, which was managed by coil endovascular embolization. In the context of pandemic, the management of vascular lesions may be performed through interventional radiological procedures that may reduce the risk of virus aerosolization and health care provider contamination.

Saliva Pepsin Concentration of Laryngopharyngeal Reflux Patients Is Influenced by Meals Consumed Before the Samples.

OBJECTIVES/HYPOTHESIS: To assess the impact of diet on the saliva pepsin concentration of patients with laryngopharyngeal reflux (LPR). STUDY DESIGN: Non-controlled Prospective Study. METHODS: Patients with positive LPR regarding hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH) were enrolled from three European Hospitals. Patients collected three saliva samples, respectively, in the morning (fasting), and 1 to 2 hour after lunch and dinner. Patients carefully detailed foods and beverages consumed during meals and before the pepsin samples. The 3-month treatment was based on the association of diet, proton pump inhibitors, alginate, or magaldrate regarding the HEMII-pH characteristics. Reflux Symptom Score (RSS) and Reflux Sign Assessment (RSA) were used for assessing the pre- to posttreatment clinical evolution. The Refluxogenic Diet Score and the Refluxogenic Score of a Dish (RESDI) were used to assess the refluxogenic potential of foods and beverages. The relationship between saliva pepsin concentration, HEMII-pH, RESDI, RSS, and RSA was investigated through multiple linear regression. RESULTS: Forty-two patients were included. The saliva pepsin concentration of the 24-hour period of testing was significantly associated with foods and beverages consumed during the testing period and the evening dinner (rs = 0.973, P < .001). RSS and RSA significantly improved throughout treatment. The level of saliva pepsin in the morning was a negative predictive factor of the therapeutic response regarding RSA and RSS (P < .036). CONCLUSIONS: Foods and beverages may significantly impact the saliva pepsin concentration of patients with LPR. Patients with high-level saliva pepsin in the morning had lower therapeutic response compared with those with low-level saliva pepsin. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:350-359, 2021.

Prevalence and Features of Laryngopharyngeal Reflux in Patients with Primary Burning Mouth Syndrome.

OBJECTIVES/HYPOTHESIS: To investigate the prevalence and features of laryngopharyngeal reflux (LPR) in patients with primary burning mouth syndrome (BMS). STUDY DESIGN: Prospective uncontrolled study. METHODS: Patients who visited our Departments of Otolaryngology-Head and Neck and Maxillofacial surgery with BMS were prospectively recruited from September 2018 to September 2020. Patients benefited from dental, maxillofacial, otolaryngological examinations, and hypopharyngeal-esophageal impedance pH-monitoring (HEMII-pH). Oral, pharyngeal, and laryngeal findings and symptoms were rated with Reflux Sign Assessment (RSA) and Reflux Symptom Score-12 (RSS-12). Patients were treated with a combination of diet, pantoprazole, and alginate. RESULTS: From the 81 included patients, 76 reported >1 pharyngeal reflux events (93.8%), accounting for 35 (46.1%), 24 (31.6%), and 17 (22.3%) acid, mixed, and nonacid LPR, respectively. Thirty-two patients had both LPR and gastroesophageal reflux disease (GERD). Thirty-eight patients benefited from pepsin saliva measurement, which was positive in 86.8% of cases. The mean scores of mouth/tongue burning, RSS-12, and RSA significantly improved from pre- to post-treatment (P < .004). At 3-month post-treatment, 62.5% of patients reported an improvement of mouth/tongue burning score. Patients with both GERD and LPR reported higher baseline RSS-12 and RSA scores. CONCLUSION: Acid, weakly acid, and nonacid LPR may be involved in the development of BMS. The use of an appropriate treatment considering the reflux features is associated with an improvement of symptoms and findings. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2627-E2633, 2021.
