Hoarseness among school teachers: A cross-sectional study from Dammam.

BACKGROUND: Voice disorders are known to be a serious occupational hazard for teachers. Compared to the general population, teachers have a greater risk of developing hoarseness of voice. The prevalence of voice disorders in teachers is 20%-50%. To the best of our knowledge, there has been no study in Saudi Arabia (SA) on the prevalence of hoarseness in teachers. MATERIALS AND METHODS: A cross-sectional survey was conducted in 13 randomly selected schools at different levels of education in Khobar, SA, between February 2016 and March 2016. Data collected included demographic data, comorbidity, smoking, school type, laryngopharyngeal reflux, hearing problems, common cold, family history, number of students, and stress. The study included teachers who were actively teaching. Teachers with laryngeal cancer and those who were not actively teaching as well as those who were on sick leave were all excluded from the study. Data were analyzed using SPSS version 20. RESULTS: Out of 400 surveys distributed, 187 teachers responded; mean age of teachers was 42.5 years and 55.1% were females. The percentage of teachers who subjectively complained of hoarseness was 27%; teachers in public schools had a higher prevalence of hoarseness than teachers in private schools. The greater the number of students per class, the more likely it was for the teacher to develop hoarseness (P = 0.038). The factors statistically significantly associated with hoarseness included smoking, acid reflux, family history of hoarseness, and work-related stress. CONCLUSION: Prevalence of hoarseness in teachers is high owing to a combination of multiple associated factors, many of which can be controlled.

Association Between Voice Handicap Index and Reflux Symptom Index: A cross-sectional study of undiagnosed general and teacher cohorts in Saudi Arabia.

OBJECTIVES: This study aimed to assess potential associations between self-reported symptoms of laryngopharyngeal reflux (LPR) and voice disorders among two undiagnosed cohorts in Saudi Arabia. METHODS: This cross-sectional study was conducted from February to April 2017 in Khobar, Saudi Arabia. Validated Arabic versions of the Reflux Symptom Index (RSI) and 10-item Voice Handicap Index (VHI-10) were distributed to 400 teachers at 13 schools and 300 members of the general population attending an ear, nose and throat clinic in Khobar. Scores of >13 and >11 on the RSI and VHI-10 indicated a potential subjective diagnosis of LPR and voice disorders, respectively. RESULTS: A total of 446 individuals took part in the study, including 260 members of the general population (response rate: 86.7%) and 186 teachers (response rate: 46.5%). The mean age was 32.5 years. In total, 62.2% complained of voice and/or reflux problems, with the remaining 37.8% not reporting/unaware of any problems in this regard. Among the teachers, 30.6% and 18.3% had positive RSI and VHI-10 scores, respectively, while 43.1% and 14.6% of the individuals from the general population had positive RSI and VHI-10 scores, respectively. Overall, VHI-10 scores were significantly associated with RSI scores (P <0.001). CONCLUSION: A significant association between RSI and VHI-10 scores suggests that there may be an association between LPR and voice disorders. These tools would therefore be a valuable method of monitoring patients; however, they cannot be used to confirm a diagnosis. Thus, more detailed studies are needed to confirm this association using a larger sample size.

Primary paranasal sinus hyalinizing clear cell carcinoma: a case report.

BACKGROUND: Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumour of salivary glands that was first described as a distinct entity in 1994 by Milchgrub et al. EWSR1-ATF1 fusion was found to be specific for this tumour. The majority of the reported cases of HCCC arise from minor salivary glands within the oral cavity. Primary HCCC of the paranasal sinus is extremely uncommon. To our knowledge, only three cases have been reported in the English literature. Herein, we present a case of HCCC of the posterior ethmoid/maxillary sinus. CASE PRESENTATION: A 63-year-old lady who presented with a long history of epistaxis. CT scan revealed a destructive mass in the left ethmoid/posterior maxillary sinus extending to the nasal cavity. Surgical excision was done and microscopic evaluation showed a tumour composed mainly of nests of clear epithelial cells separated by fibrocellular and hyalinized septa with extensive bone destruction. The tumour cells expressed CK5/6, EMA and p63 immunohistochemically but were negative for S100 protein, PAX-8, RCC and CK7. Sinonasal renal cell-like adenocarcinomas, myoepithelial carcinoma and metastatic renal cell carcinoma were excluded by radiological and immunohistochemical studies. Fluorescence in situ hybridization analysis revealed an EWSR1 gene rearrangement. Postoperative radiation was administrated and the patient did not show recurrence or distant metastasis 4 months after the surgery. CONCLUSION: Head and neck region have many tumours that demonstrate clear cell changes on histology. Thus, the differential diagnosis for HCCC is wide. Awareness of this rare entity and the possibility of it is arising in unusual location is necessary. EWSR1-AFT1 fusion, a consistent finding in HCCC, can be used to confirm the diagnosis.

Type I Thyroplasty in Previously Irradiated Patients: Assessing Safety and Efficacy.

OBJECTIVES: (1) Review and report our experience performing medialization thyroplasty (MT) in previously irradiated patients and (2) compare complications and voice outcomes in 2 cohorts (irradiated vs nonradiated) to evaluate safety and efficacy. STUDY DESIGN: Case series with chart review. SETTING: Academic medical center. SUBJECTS: All patients (44 total) who underwent MT from 2011 to 2015. METHODS: Demographic data, complications, and acoustic and subjective voice outcome parameters were collected. The complication rates and voice outcome results were compared between 2 cohorts: patients with a history of radiation to the neck versus those with no radiation history. RESULTS: There were 7 previously irradiated patients and 37 nonradiated patients, with median follow-up of 314 and 538 days, respectively. One complication was noted in each group, and this complication rate was not significantly different (P = .26). Both cohorts demonstrated significant postoperative improvement in subjective voice assessment (P = .04, P < .0001) as well as maximum phonation time (P = .02, .001) when compared with preoperative data. CONCLUSIONS: Our study suggests that MT can be safely and effectively performed in irradiated patients. We found no statistically significant difference in the safety of performing MT in irradiated versus nonradiated patients, and there was significant improvement in subjective voice parameters and maximum phonation time in both groups. A larger prospective study is required to statistically determine whether the significant improvements in objective parameters seen in the nonradiated group are present in irradiated patients as well.

The effect of endoscopic olfactory cleft polyp removal on olfaction.

BACKGROUND: The presence of olfactory cleft polyps in chronic rhinosinusitis with nasal polyposis is well documented, but the effect of endoscopic olfactory cleft polyp surgery on olfaction, versus observation, has not been well studied. This analysis assessed if microdebridement of olfactory cleft polyps yields significant objective smell improvements in those with anosmia or hyposmia. METHODS: A randomized prospective single-blinded study was performed on patients undergoing bilateral endoscopic sinus surgery with profound bilateral nasal polyposis, excluding those younger than 18 years or without olfactory polyps. A preoperative University of Pennsylvania Smell Identification Test (UPSIT), visual analog scale (VAS), and sinonasal outcomes 20 score (SNOT-20), and a follow-up at 6 months was performed. Two cohorts were created, including one with cleft polyp removal (group A) and one with cleft polyps left in place (group B). RESULTS: There were 10 patients in group A and 7 in group B. By using the Wilcoxon signed rank test, the two groups were individually analyzed for changes in the preoperative UPSIT, VAS, and SNOT-20 versus the 6-month test results. In group A, the improvement in the UPSIT, VAS, and SNOT-20 were statistically significant at p < 0.05. For group B only the improvement in the VAS was statistically significant, at p < 0.05. There was a statistically significant difference in clinical smell improvement between group A and B at 6 months (p = 0.00512). CONCLUSIONS: Evidence exists that olfactory cleft polyp surgery improves olfactory function outcomes. Long-term data beyond 6 months is needed to further validate these early promising outcomes.
