Myiasis, a parasitic infestation caused by dipteran larvae in living humans or animals, is rarely encountered postmortem. Here, we report a case of myiasis identified during postmortem inspection in a 40-year-old man with a 10-year history of untreated schizophrenia. During the winter between late 2022 and early 2023, the decedent walked outdoors barefoot and sustained frostbite and was advised to undergo limb amputation at a university hospital in March 2024. He died at home in late May 2024. At the scene, the body showed displaceable livor mortis and absence of rigor mortis, suggesting a short postmortem interval. Severe necrosis was present below the knees, and numerous third-instar larvae without postfeeding stage were observed within the necrotic tissue, suggesting myiasis development at the frostbite sites. Species identification via larval sampling was not possible; thus, photographic analysis was attempted. The larva at the most advanced developmental stage was most likely a third-instar Lucilia sericata, the most common species causing myiasis in Korea. Assuming a skin temperature of 34°C under blanket coverage, the estimated post-oviposition interval ranged from 38.9–71.7 hours. Considering the estimated postmortem interval, the oviposition may have occurred antemortem. Since myiasis can indicate neglect or contribute to death, forensic pathologist should assess whether the postmortem interval aligns with the developmental stage of the larvae. For accurate forensic entomological analysis, adequate sampling of larvae is essential during postmortem inspections.

A 45-year-old woman with a history of migraine experienced thunderclap headaches, after which cerebral vasospasm was confirmed by brain magnetic resonance angiography. Nimodipine treatment initially improved the headache, but moderate daily headaches persisted despite vasospasm resolution. Conventional headache medications including topiramate, propranolol and amitriptyline proved ineffective. Treatment with fremanezumab, a calcitonin gene-related peptide (CGRP)-targeted therapy, resulted in significant reduction of headache frequency and intensity after 3 months. This case suggests the potential effectiveness of CGRP inhibition for persistent headaches following reversible cerebral vasoconstriction syndrome.

A 79-year-old man visited neurology clinic due to gait ataxia and vertigo for 10 months. Neurologic examination revealed saccadic pursuit, mild dysmetria, impaired tandem gait, and areflexia that recovers after exercise. The amplitude of compound muscle action potentials recorded on the abductor digiti minimi increased up to 6,639.4% during repetitive nerve stimulation at 50 Hz stimulation. This case demonstrates that clinicians should consider Lambert-Eaton myasthenic syndrome as a differential diagnosis when a patient complains of gait ataxia and vertigo.
