[Sick building syndrome: three case reports].

SBS--sick building syndrome--is a set multi-organ symptoms related to long-term staying in "sick buildings". These are modern, energy saving, air tight buildings with reduced ventilation. As a result of such construction, harmful, air-borne substances issued by interior decoration materials, air-conditioning systems and working people are cumulated. The study presents three cases of allergic patients whose original allergic illnesses got aggravated as an effect of: 1) staying in a freshly redecorated room, 2) staying in a fully air-conditioned room, 3) long-term exposition to bacteria and fungi allergens developing in old, used up filters of a car air-condition system.
