  1. Occupational skin diseases Dr Omid Aminian

  2. Occupational Dermatoses • Occupational association first made by Ramazzini • Percival Pott occupational induced cancer of the scrotum in chimney sweeps in 1775 • 25% of work-related illness

  3. Chemicals Acids Alkalis Solvents Oils Detergents Resins Plastics Metals Petroleum product Plant & wood Physicals Temperature Ionizing radiation Non ionizing radiation Biologic Viruses (orf-wart-herpes) Bacteria (anthrax-erisopeloid) Fungi (candida-dermatophyte) Parasites (scabies- (schistosomiasis) Mechanicals Pressure Friction Vibration Work place agents that induced skin disorder

  4. Important causal agents of occupational skin illness • MachineryCutting oils Solvents • Metal productsSolvents Metallic salts • Electronic equipmentSolvents Plastic & resin • Food productsFruits & vegetables Soap & detergents • Agriculture Chemicals Fruits & nuts • Health servicesSoap & detergents Infectious agents

  5. Occupational dermatoses Occupational injuriesLaceration & Puncture %81Chemical & Thermal burn %14Others%5 Occupational Illness Contact dermatitis %90 Infectious diseases %5/5 Neoplasm & others %4/5

  6. Occupational Dermatoses • Seven common conditions 1. irritant contact dermatitis 2. allergic contact dermatitis 3. photosensitive dermatitis 4. pigment alterations 5. acneiform conditions 6. contact uticaria 7. malignancies

  7. Contact Dermatitis • 90% of skin lesions seen in work placep 80% -- irritant 20% -- allergic

  8. Irritant Contact Dermatitis • Erythema to eczematous changes to papules, vesicles • Caused by chronic exposure to mild irritants Fissuring • Hyperpigmentation • Hardening

  9. Skin disease andpossible etiologies • Ulcerationstrong acids (HF-H2SO4) strong alkali (NaOH-KOH) solvent (acrylonitrile-CS2) • Folliculitis&arsenic trioxide-glass fiber acne PCB oil- • Milia occlusive dressing UV-IR • Leukoderma phenol-cresol • Alopeciathallium-chloroprene • Urticaria cosmetics-plants • Granuloma silica-beryllium • Lichenoid p-phenylenediamine • Scleroderma vinyl chloride-silica

  10. OCCUPATIONAL HISTORY • Description of all job • Work exposure • Timing of symptom • Illness among other workers • Non-work exposure

  11. PREVENTION • Hazards identification • Engineering controls • Chemicals substitution • Personal hygiene • Personal protection gloves,barriercream,clothing 6. Education & training • Preemployment & periodic examination

  12. AGENTS ASSOCIATED WITH DERMAL INJURIES
