Weapons of War and Dermatology: A Comprehensive Review of Cutaneous Manifestations From Chemical Warfare Agents, Part II: Nerve Agents, Cyanides, and Riot Control Agents
Bibliographic record
Abstract
This second installment in a two-part comprehensive review explores chemical warfare agents that primarily cause systemic toxicity with secondary cutaneous manifestations: nerve agents, cyanides, and riot control agents (RCAs). While these agents are primarily known for their systemic effects, their dermatological manifestations can provide critical diagnostic clues in exposure scenarios. Part II examines the G-series, V-series, GV-series, and Novichok nerve agents; various cyanide compounds; and both historical and modern RCAs. For each agent class, the review details their historical contexts, physicochemical properties, mechanisms of action, dermatological manifestations, and current treatment approaches. The widespread use of RCAs in civilian law enforcement underscores the practical relevance of understanding these compounds. Additionally, despite international prohibitions, some of these agents continue to pose threats in modern conflicts and targeted assassinations. The review highlights the crucial role dermatologists can play in multidisciplinary response teams, as recognizing characteristic cutaneous changes may facilitate rapid diagnosis and life-saving intervention. Future preparedness efforts should incorporate specialized training for health care providers, emphasizing the distinct dermatological presentations of these agents.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
