RESUMO

BACKGROUND: Carcinoma is a rare complication of pharyngeal diverticula. There is a paucity of information about its incidence, presentation, management, and treatment outcomes. A systematic review and analysis of all reported cases has been carried out. METHODS: A comprehensive literature search for pharyngeal diverticula carcinoma was performed from 1896 to 2008. Descriptive analyses were carried out by analyzing the absolute and relative frequencies. Comparison of groups was illustrated with Kaplan-Meier curves and tested statistically using the log-rank test. A cohort of 56 patients with benign pharyngeal diverticula was selected for comparison with the accumulated cohort of pharyngeal diverticula carcinoma, and a Fisher's exact test was carried out on the extracted clinical characteristics of this cohort to evaluate for differences between benign and malignant pharyngeal diverticula. RESULTS: Forty-three articles reporting 60 cases satisfied the inclusion criteria. The mean age at presentation was 68.8 years (SD = 9.8 years). Five-year cancer-specific survival (CSS) rates for patients who underwent excision alone, excision + postoperative radiotherapy (PORT), and radiotherapy alone were 0.74 versus 0.63 versus 0.0, respectively (p = .39). Five-year CSS rates of patients <65 versus ≥65 years were 0.43 versus 0.78, respectively (p = .046). CONCLUSION: Irregular symptoms in benign diverticula should raise suspicion of malignancy. Management consists of surgical excision ± PORT. © 2014 Wiley Periodicals, Inc. Head Neck 36: 1368-1375, 2014.

RESUMO

BACKGROUND: Viagra and PDE-5 inhibitors use has mushroomed since its launch over a decade ago. A growing body of evidence indicates significant morbidity associated with the side effect profile of this class of drug. Hearing loss associated with PDE-5 inhibitor use has recently been reported, but few studies have evaluated the causal link. AIM: To review and scrutinise the current literature on the subject and propose possible physiologic mechanisms and to investigate the global reporting of this side effect. METHODS AND MATERIALS: Pharmacovigilance agencies around North America, Europe, and Australasia were contacted requesting reports of hearing loss associated with PDE-5 inhibitors. Reports were scrutinised to exclude those where others causes of hearing loss existed. RESULTS: Forty-seven cases of sensorineural hearing loss with a temporal association with PDE-5 inhibitor ingestion were obtained from both published literature and pharmacovigilance agencies. Cases had a mean age 56.6 years, male-to-female ratio of 7:1. Eighty-eight percent of reports were unilateral with an even left/right distribution. Hearing loss occurred within 24 hours of ingestion of PDE-5 inhibitor in 66.7% (n = 18) of cases. Sildenafil accounted for over 50% of cases. CONCLUSION: There is increasing evidence that PDE-5 inhibitors may induce sensorineural hearing loss via plausible physiological mechanisms. There needs to be more awareness of this disabling side effect among healthcare professionals responsible for prescribing this drug.
