Three cases of uncommon medication‐associated osteonecrosis of temporal bone

Abstract Introduction Medication‐related osteonecrosis of the temporal bone is rare and has been reported to be associated with the use of anti‐resorptive and biologic agents. Here, we present the first case of tyrosine‐kinase inhibitor‐related external auditory canal (EAC) osteonecrosis as well as two cases related to anti‐resorptive therapies. Methods A retrospective case series. Results Case one: an 84‐year‐old female presented with chronic otitis externa and osteonecrosis of EACs bilaterally. She had a history of osteoporosis treated with denosumab and risedronic acid. She successfully underwent left EAC reconstruction using an inferiorly‐based pedicle periosteal flap while the right ear canal was managed conservatively. Case two: a 69‐year‐old male presented with osteonecrosis of the right EAC. He had a history of osteoporosis treated with alendronic acid and zoledronic acid. His osteonecrosis is conservatively managed with local debridement and antibiotic application. Case three: a 60‐year‐old male presented with osteonecrosis of the right inferior EAC. He had a history of chronic myelogenous leukemia treated with a tyrosine‐kinase inhibitor, imatinib. After failing conservative therapy, he underwent right ear canal reconstruction using a periosteal vascular pedicle flap without complication and experienced complete resolution to his symptoms. Conclusion Anti‐resorptive agents and/or tyrosine kinase inhibitors may lead to dysregulation of bone remodeling and result in rare cases of temporal bone osteonecrosis. When a local debridement and antibiotic therapy fail, definitive surgical excision of necrotic bone with subsequent reconstruction of the EAC may offer patients a possible resolution in symptoms

Demographics and Spatio-Temporal Signature of the Biotoxin Domoic Acid in California Sea Lion (\u3ci\u3eZalophus californianus\u3c/i\u3e) Stranding Records

California sea lions (Zalophus californianus) in otherwise good nutritional condition have been consistently affected by the marine biotoxin domoic acid since the late 1990s. In this study we evaluated the temporal and spatial stranding patterns of suspected and confirmed cases of domoic acid intoxicated sea lions from 1998 to 2006, using records of strandings along the California coast obtained from members of the California Marine Mammal Stranding Network. The majority of domoic acid cases were adult females (47%–82% of the total annual domoic acid cases), a contrast to strandings that were not related to domoic acid, which were generally dominated by juveniles and pups. Exposure to this biotoxin led to a 6.67-fold increase in adult female strandings in 2000, and a 5.44-fold increase in adult female deaths in 2006, relative to strandings and deaths of adult female not affected by domoic acid. Domoic acid cases have occurred annually since 1998 (except for 1999) between April and August, with clusters centered primarily at Pismo Beach (San Luis Obispo County), as well as at other beaches in San Luis Obispo, Monterey, Santa Cruz, Santa Barbara, Orange, and San Diego counties. The larger ecological and population level implications of increased domoic acid strandings and deaths, particularly among adult female sea lions, warrant further attention and need to be investigated
