Objective:
To describe a series of patients with clinically significant lead poisoning.
Methodology:
A case series of nine patients with lead poisoning who required inpatient management, identified through a Clinical Toxicology Service.
Results:
Nine children presented with clinically significant lead poisoning. The median serum lead was 2.5 micro mol/L (range 1.38-4.83). Eight of the children were exposed to lead-based paint, with seven due to dust from sanded lead paint during house renovations. Serial blood determinations suggested re-exposure in four of the patients, and in one of these patients the re-exposure was from a different source of lead. Eight of the patients required chelation therapy.
Conclusions:
Serious lead poisoning continues to occur and there appears to be complacency regarding the hazard posed by lead paint in old houses.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
