ABSTRACT
BACKGROUND: Laryngopharyngeal reflux (LPR) refers to the backflow of acidic stomach content into the larynx, pharynx, and upper aerodigestive tract. The diagnosis of LPR is based on the patient's history and findings of the laryngoscopy associated with LPR. Other possible manifestations consistent with LPR symptoms include laryngeal cancer, vocal fold granulomas, Reinke's space edema, and vocal polyps. In this study, we compared the characteristics of patients with LPR symptoms and incidental laryngeal findings (ILF) in the laryngoscopic evaluation to those without ILF (WILF). OBJECTIVES: Determine the characteristics of LPR-symptomatic patients with ILF versus WILF. METHODS: In this retrospective study, we examined 160 medical charts from patients referred to the otolaryngology clinic at Galilee Medical Center for LPR evaluation 2016-2018. The reflux symptoms index (RSI), reflux finding score (RFS), and demographics of the patient were collected. All patients with a positive RSI score for LPR (RSI > 9) were included, and the profiles of patients with versus without ILF on laryngoscopy examination were compared. RESULTS: Of the 160 patients, 20 (12.5%) had ILF during laryngoscopy. Most had vocal cord findings such as leukoplakia (20%), polyps (15%), and nodules (20%). Hoarseness, throat clearing, swallowing difficulty, breathing difficulties, and total RSI score were significantly higher in patients with ILF. CONCLUSIONS: Evaluation of LPR symptoms may provide otolaryngologists with a tool to identify patients with other findings on fiberoptic laryngoscopy. A laryngoscopic examination should be part of the examination of every patient with LPR to enable diagnosis of incidental findings.

Olfactory neuroblastoma (ONB) is a rare tumour of the skull base, typically originating from the nasal cavity and around the cribriform plate. We present the rare case of ONB originating from and limited to the sphenoid sinus in a 42-year old lady. Pre-operatively the lesion was thought to be a sinonasal polyp and underwent functional endoscopic sinus surgery (FESS) and total excision of the polypoid lesion. Review of histology unexpectedly revealed ONB. She underwent further surgery to ensure wide local excision was achieved with negative margins on histology, followed by radiotherapy. This is only the third reported case of ONB limited to the sphenoid sinus and the ninth reported case of primary sphenoid ONB in the literature. We review the literature pertaining with primary sphenoidal ONB here and suggest complete resection is indicated in ectopic ONB, not unlike classical ONB. There may be a role for adjuvant oncological treatments and lifelong follow up in a multidisciplinary approach is recommended.

BACKGROUND: Laryngopharyngeal reflux (LPR) is an extra-oesophageal variant of gastro-oesophgeal reflux disease. Patients often do not present with the classic reflux symptoms of heartburn or regurgitation. Accurate diagnosis of LPR can be challenging. The reflux finding score (RFS) is system based on the assessment of eight parameters seen on fibre optic laryngoscopy, used to determine the presence and the severity of laryngopharyngeal reflux (LPR). Scoring the RFS is subjective and highly dependent on the examiner's eye and experience. In this study, we investigated the inter-rater reliability between three otolaryngologists scoring a large library of video-recorded laryngoscopies for RFS. AIM: To evaluate the usefulness of RFS in daily clinical practice by assessing inter-rater reliability among otolaryngologists when interpreting a bank of identical fibre optic laryngoscopy examinations. METHOD: Three board-certified otolaryngologists with different subspecialist interests examined video-recorded fibre optic laryngoscopies of 193 patients with or without LPR symptoms and rated each video for RFS. Statistical analysis was performed. Results were compared to determine the inter-rater reliability. RESULTS: Fair to poor correlation was found between the three expert raters for total RFS score, as well as for RFS component items with nonbinary outcomes. For the dichotomous items, the inter-rater reliability was slight to moderate. Inter-rater correlation for determining whether an examination is pathological or nonpathological was fair. CONCLUSION: The RFS alone was not reliable for confirming the diagnosis of LPR, due to low inter-rater reliability and the subjective nature of the scoring system.

BACKGROUND: upper airway complications are common sequelae of endotracheal tube (ETT) intubation, and systemic corticosteroids are considered a mainstay treatment for this problem. Drug-eluting ETT may present an attractive option for topical steroid delivery while avoiding systemic side effects and improving the therapeutic outcome. The objective of the present study is to evaluate the reduction of tube-related tracheal morbidity via a self-designed steroid-eluting ETT with controlled sustained release properties in an animal model. METHODS: steroid-eluting ETTs were coated by poly(lactic-co-glycolic acid) -electrospun nanofibers loaded with mometasone furoate (MF) as a model drug. Animals were randomly assigned into three equal groups: non-intubated, blank-ETT, and loaded-ETT. The intubation interval was 1 week. Specimens were analyzed by histology, specific fibrosis staining, and scanning electron microscopy (SEM). RESULTS: the blank-ETT group exhibited a significant increase in tracheal mucosal thickness compared to the loaded-ETT and control groups. Average tracheal mucosal thickness was 112 ± 34, 242 ± 49, and 113 ± 43 µm in the control, blank-ETT, and loaded-ETT groups, respectively. The blank-ETT group exhibited a significant increase in tracheal fibrosis compared to the loaded-ETT and control groups. Relative fibrosis values were 0.07 ± 0.05, 0.154 ± 0.1, and 0.0984 ± 0.084% for the control, blank-ETT, and loaded-ETT groups, respectively. While SEM imaging showed normal surface structures in the control group, intubated blank-ETT rats showed severe surface structural damage, whereas only mild damage was observed in the loaded-ETT group. CONCLUSIONS: local sustained release of MF via a self-designed drug-eluting ETT is a potential therapeutic approach which may significantly reduce tube-related upper airway morbidity.

Fungal rhinosinusitis (FRS) is inflammation of the paranasal sinus mucosa due to fungal infections, which can be invasive or non-invasive. The occurrence of a sphenoid mucocele with a fungal ball is rare. We report a case of sphenoid sinus mucocele with a fungal ball caused by Scedosporium apiopermum in a 32-year-old female who presented to the Emergency Department with persistent headache not relieved on medications. The radiological images showed a mucocele with clival osteomyelitis. Urgent endoscopic examination and debridement was undertaken which demonstrated a mucocele with fungal ball. Microbiological examination confirmed it to be Scedosporium apiopermum.

OBJECTIVES: Post-tonsillectomy pain control is still considered a challenge. Topical agents would seem to be an ideal, safe option. Our objective was to compare the efficacy of mouthwash preparation with anti-inflammatory, anesthetic, and analgesic properties (Tantum Verde®, 0.15% benzydamine hydrochloride) with that of placebo in improving post-tonsillectomy morbidity. METHODS: A prospective, double blind, randomized clinical trial was performed. Patients older than 12-years-of-age who underwent tonsillectomy were recruited. Participants were randomized into 2 groups to receive either 0.15% benzydamine hydrochloride (TV) mouthwash solution (study arm) or a placebo solution. They were instructed to gargle the intervention they received 3 times a day for 7 days following surgery. Primary outcomes were intensity and duration of post-operative pain (using VAS visual analogue score) during a 2-week follow-up period. Secondary outcomes were pain medication demand, readmission, incidence of post-operative bleeding, hospital stay duration, and time to resume normal solid diet. RESULTS: Thirty-nine patients completed the study, of whom 23 received TV and 16 received placebo. The mean age was 23.1 years. There was no significant difference between the groups in the primary or secondary outcomes. CONCLUSIONS: The data suggest that topical treatment with TV mouthwash solution was not found to be superior to placebo in the management of post-tonsillectomy pain, bleeding, and return to a regular solid diet. Further research studies should be designed to investigate the ideal treatment for reducing post-tonsillectomy morbidity. CLINICAL TRIAL REGISTRATION: NIH identifier: NCT02190762; IRB NHR002814.

OBJECTIVES: To establish clinical criteria for performing computed tomography scan for suspected upper digestive tract fishbone. METHODS: This is a prospective study of all adult patients referred to the otolaryngology emergency department at our medical center for suspected fishbone in the upper digestive tract after no fishbone was seen on physical examination. The patients were divided into two groups: 1) The first was a high clinical suspicion group, which included patients with at least one of the following criteria: drooling, accumulation of saliva in the sinus piriformis, fever, referral 24 hours after the ingestion with worsening/continuing symptoms, and readmission. These patients underwent nonenhanced CT scan (NECT) of the neck. 2) The second was a low clinical suspicion group, which included patients discharged with no NECT performed. These patients were followed at 1 week and 3 months. RESULTS: One hundred and fourteen patients were included in the study; the median age was 41 years. Half of the patients arrived at the emergency department within 7 hours. There were no false negatives. The negative predictive value and sensitivity were 100%. Positive predictive value and specificity were 28.5% and 65%, respectively. Referral to the emergency department 24 hours after the ingestion with continuing symptoms had the highest false positive rate. CONCLUSIONS: Our clinical criteria score for excluding foreign body fishbone in the upper aerodigestive tract was established. According to this score, a NECT can be spared in about 75% of all cases, thus reducing unnecessary ionizing radiation, stay at the emergency department, and costs with a very high NPV of almost 99%.

Laryngeal and tracheal morbidity is a common complication of endotracheal tube (ETT)-based airway management, and manifests as local irritation, inflammation, and edema. Systemic corticosteroids are commonly administered to manage these conditions; however, their efficacy is inadequate and limited by potential severe side effects. In the present study, a steroid delivery system for local therapy was developed to generate relatively high local drug concentrations and to improve drug efficacy. ETTs were coated with electrospun poly (lactic-co-glycolic acid) (PLGA) nanofibers loaded with mometasone furoate (MF), creating a microscale thick layer. MF exhibited sustained release from coated ETTs over 14days in vitro. An in vivo efficacy study in rats demonstrated the therapeutic benefit of MF-coated ETTs over bare ETTs, as measured by reduced laryngeal mucosal thickness and submucosal laryngeal edema. The fiber coating remained intact during tube intubation and extubation, demonstrating good adhesion to the tubes even after 24h in aqueous solution at 37°C. These findings demonstrate the potential of drug-loaded ETTs to revolutionize the standard of care for endotracheal intubation.

BACKGROUND: Fine-needle aspiration cytology (FNAC) is used to provide rapid diagnostic information regarding masses of the head and neck. To achieve good results, adequate training is essential. OBJECTIVES: To evaluate the efficacy of FNAC in the diagnosis of head and neck masses performed by residents and attending physicians. METHODS: Palpable guided FNA biopsies from 166 consecutive patients with head and neck masses, excluding thyroid, who were treated in our department between 2008 and 2010 were retrospectively reviewed. Accuracy, sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: A total of 193 FNACs were performed in 161 patients (5 patients were excluded due to age under 18). Mean age was 57.3 years; female to male ratio was approximately 5:4. Most FNACs were performed in masses in the parotid gland (37.3%), 14.5% in the posterior neck, 19.1% in the lateral neck, 15% at level 1, and 9.3% at level 6. The median size of the masses aspirated was 2 cm. Most FNACs were performed by an experienced physician (2.5:1). About 25% of the patients required a second FNAC. Almost 70% of FNACs were diagnostic. Of these, 71.2% were of benign processes and 28.8% of malignancies. CONCLUSIONS: An FNAC of a palpable mass in all sites of the neck, excluding the thyroid, can be done as an office procedure with reasonable results without imaging guidance. About 25% of patients will require another biopsy. The procedure is not difficult to master, as evidenced by the fact that there were no differences in the results of FNACs performed by an attending otolaryngologist or a resident.
