Lead poisoning from retained bullets. Pathogenesis, diagnosis, and management

Area of Science:

• Toxicology
• Metallurgy
• Medical Diagnostics

Background:

• Lead intoxication (plumbism) from retained bullets is an uncommon but serious complication.
• Bullets lodged in joint spaces or pseudocysts pose a higher risk.

Observation:

• Subtle clinical signs like anemia, abdominal colic, nephropathy, or neurological decline in patients with retained bullets may indicate plumbism.
• Intercurrent metabolic stress (e.g., infection, endocrinopathy, alcoholism) can precipitate lead poisoning.

Findings:

• Mass spectrometric stable isotope dilution analysis is a highly reliable diagnostic method for lead intoxication.
• Chelation therapy is recommended before surgical intervention to minimize lead release from bone.

Implications:

• Awareness of plumbism in patients with retained bullets is critical for timely diagnosis and treatment.
• Proactive management, including chelation, can prevent fatal outcomes and complications associated with lead poisoning.
