Caustic ulcers caused by cement

M Hannuksela, R Suhonen, J Karvonen

The British Journal of Dermatology

|November 1, 1976

Summary

This summary is machine-generated.

Wet cement exposure caused deep knee and foot ulcers in seven patients. The high alkalinity of calcium hydroxide in cement is the likely cause of these chemical burns.

Area of Science:

Dermatology
Occupational Health
Toxicology

Background:

Chemical burns from occupational exposures are a significant concern in construction and industrial settings.
Wet cement, a common material, is known to be alkaline due to calcium hydroxide, posing a risk for skin damage.

Observation:

Seven patients presented with similar deep ulcerations, primarily on the patellae, after prolonged kneeling on wet concrete.
One patient developed ulcers on the feet due to direct contact with wet cement inside footwear.
Ulcer development occurred within 12 hours of exposure, with varying exposure times from 2 to 6 hours.

Findings:

The consistent observation across all cases was the development of deep ulcerations attributed to wet cement exposure.
The high alkalinity of calcium hydroxide present in wet cement was identified as the sole apparent causative agent.

Related Experiment Videos

The pattern of ulceration correlated with the points of direct and prolonged contact with the alkaline substance.

Implications:

This case series highlights the severe dermatological risks associated with wet cement, particularly chemical burns.
Awareness and implementation of protective measures, such as appropriate personal protective equipment, are crucial for preventing cement-induced injuries in occupational settings.
Understanding the mechanism of injury, specifically the role of calcium hydroxide alkalinity, can inform prevention strategies and clinical management of such burns.
