Rationale: Steven-Johnson syndrome (SJS) is characterized by severe illness, rapid progression, and high mortality rates, with the vast majority of cases induced by medications. Botulinum toxin, a neurotoxin produced by Clostridium botulinum, has not been reported in the literature as a causative agent of SJS.
Patient Concerns: A 56-year-old male patient, who underwent surgery for cerebral hemorrhage, developed widespread patchy annular papules following the injection of botulinum toxin into the masseter muscle.

Amyotrophic Lateral Sclerosis (ALS) is a complex neurodegenerative disease primarily affecting motor neurons, leading to progressive muscle atrophy and paralysis. This review explores the role of Schwann cells in ALS pathogenesis, highlighting their influence on disease progression through mechanisms involving demyelination, neuroinflammation, and impaired synaptic function. While Schwann cells have been traditionally viewed as peripheral supportive cells, especially in motor neuron disease, recent evidence indicates that they play a significant role in ALS by impacting motor neuron survival and plasticity, influencing inflammatory responses, and altering myelination processes.

While rising global rates of neurodegenerative disease encourage early diagnosis and therapeutic intervention to block clinical expression (secondary prevention), a more powerful approach is to identify and remove environmental factors that trigger long-latencybrain disease (primary prevention) by acting on a susceptible genotype or acting alone. The latter is illustrated by the post-World War II decline and disappearance of Amyotrophic Lateral Sclerosis and Parkinsonism-Dementia Complex (ALS/PDC), a prototypical often-familial neurodegenerative disease formerly present in very high incidence on the island of Guam. Lessons learned from 75 years of investigation on the etiology of ALS/PDC include: the importance of focusing field research on the disease epicenter and patients with early-onset disease; soliciting exposure history from patients, family, and community to guide multidisciplinary biomedical investigation; recognition that disease phenotype may vary with exposure history, and that familial brain disease may have a primarily environmental origin.
