Ototoxicity Review: A Growing Number of Non-Platinum-Based Chemo- and Immunotherapies.

OBJECTIVE: To raise awareness of the growing list of non-platinum-based chemo- and immunotherapeutic agents that have been associated with ototoxicity and to introduce the possible mechanism of ototoxicity of these agents. DATA SOURCES: PubMed, Embase, and Web of Science. REVIEW METHODS: A systematic review was performed following the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses). PubMed, Embase, and Web of Science databases were searched for published reports of ototoxicity from non-platinum-based chemo- and immunotherapeutic agents in adult and pediatric patients. Therapies that utilized any platinum-based agent were excluded. CONCLUSIONS: Ototoxicity from non-platinum-based chemo- and immunotherapies is an evolving problem. There were 54 reports-39 case reports and 15 cohort studies-documenting ototoxicity from 7 agents/combination therapies. Of these reports, 37 (69%) were published within the last 15 years (after 2005). No recovery of hearing was documented in 21 of 56 cases (38%). Pretreatment audiograms were uncommon (19/54 studies, 35%), despite documented ototoxic associations. IMPLICATIONS FOR PRACTICE: There is a growing number of novel, ototoxic, non-platinum-based chemo- and immunotherapeutic agents with various potential mechanisms of action. Otolaryngologists will need to prioritize awareness of these agents. This growing list of agents, many of which have reversible effects, suggest a need for standardized ototoxicity monitor protocols so that appropriate and timely management options can be implemented.

Thoracoscopic Treatment of Giant Pulmonary Bullae.

BACKGROUND: Giant pulmonary bullae (GPB) is rare. The aim of this study was to evaluate the functional results of video-assisted thoracic surgery (VATS) in the treatment of GPB and the factors associated with complications following VATS resection for GPB. MATERIALS AND METHODS: From January 2010 to January 2015, 44 GPB patients underwent surgery with VATS. Individual GPB patient characteristics and surgical outcomes were evaluated. The patients were separated into two groups (an emphysematous group and a nonemphysematous group), and differences between the respective groups were investigated. RESULTS: Although there were no mortalities within a 30-d postoperative period among the 44 GPB patients treated surgically with VATS, 28 experienced postoperative complications, of which the most common were air leaks. VATS for GPB resulted in obvious improvements in symptoms and lung function in the majority of cases. Among 26 patients with preoperative dyspnea, the symptoms of 22 patients (84.62%) improved after treatment with VATS resection for GPB, and the mean forced expiratory volume in 1 s increased from 2.24 L preoperatively to 2.5 L postoperatively (P = 0.02). The complication rate of patients aged >48 y, who smoked and had emphysema, was significantly higher than that of those who did not smoke and did not have emphysema (79.2% versus 45%, P = 0.019; 85.7% versus 25%, P < 0.05; 88% versus 31.6%, P < 0.05). These characteristics could be associated with complications. CONCLUSIONS: VATS resection is a safe and effective treatment for GPB and leads to improvements in symptoms and lung function. Patients >48 y, who smoked and had emphysema, were more likely to experience postoperative complications. There could be a relationship between these characteristics and the patients' postoperative complications.
