Nasal myiasis in myasthenic crisis, a case report and literature review. (2020) - Katabi, Abdulrahman
Abstract: We are reporting a unique case of drosophila larva nasal myiasis (NM) in a 72-year-old male patient admitted to the ICU with diffuse muscle weakness and respiratory failure due to myasthenia gravis crisis and septic shock due to pseudomonas pneumonia. The myiasis was noticed on the third day of admission two days following traumatic insertion of a nasogastric tube. The patient underwent nasal endoscopic mechanical extraction and lidocaine nasal spray with saline nasal flushes. To our knowledge, this is the first case report of NM in a myasthenia gravis (MG) patient. Chronic muscle weakness in MG patients might play a role in having NM as these patients are less likely to be able to protect themselves from flies. Managing NM in our patient was challenging due to the potential neurologic side effects of most of treatment options mentioned in the literature.
