Slides 61 to 65

Index of Occupational Dermatoses Slides

Slide 61 - Leather buffer

SLIDE 61 - Leather buffer
Occupational marks or professional stigmata, such as these knuckle pads in a leather buffer, provide distinctive clues as to occupation, but seldom result in disability. Other examples are coal miner's tattoos and violinist's or fiddler's neck.

Slide 62 - Chipper

SLIDE 62 - Chipper
High frequency pneumatic tools such as chippers, electrical tools, chain saws and grinders can produce Raynaud's phenomenon or "vibration white fingers" among users. Redesign of these tools utilizing vibration dampers has been of some help in prevention.

Slide 63 - Painful white fingers

SLIDE 63 - Painful white fingers
The hands are affected by paroxysmal attacks of numbness and blanching and pain of the fingers. This phenomenon may also be precipitated by exposure to cold. The initial pallor is succeeded by a slight hyperemia and in some cases by cyanosis. Gangrene and other degenerative bone changes may result.

Slide 64 - Physical Agents

SLIDE 64 - Physical Agents
Physical agents - heat, cold and radiation - are a third direct cause of occupational dermatoses. Heat accounts for burns, sweating, erythema and telangiectasia. Cold can bring on Raynaud's disease, trench foot and frostbite. Radiation causes keratoses, sunburn, radiodermatitis, photosensitivites and skin cancers.

Slide 65 - Hot water burn

SLIDE 65 - Hot water burn
Hot water produced these first and second degree burns on the forearm of a kitchen worker. Immediate ice water immersion would have reduced the depth and extent of the burn.
