Toxic Oil Syndrome (TOS) is a previously unreported condition which affected more than 20,000 people in Spain in 1981 and whose natural history is unknown.
In 1993-94, a stratified random sample of 1400 survivors was drawn to measure their health status through clinical examination and their self-perception of well-being through the Nottingham Health Profile Questionnaire (NHPQ).
Two-thirds of the sample population responded ; indirect estimates suggest that selection bias was limited.
Clear and intermediate signs of neuropathy were found in one-fifth and one-half of the patients, respectively.
One-fourth and one-sixth showed some degree of scleroderma and contractures.
All conditions were more frequent in women than in men and in age>50 than in younger ages.
Although no concurrent control group was included in the study, prevalences of these conditions are well above expectations and are largely attributable to TOS.
NHPQ scores increased with age in both sexes up to age 50, after which they reached a plateau (with values around 48 in men and 62 in women).
Scores were associated to the occurrence of peripheral neurological changes, contractures, and scleroderma-like conditions.
A multivariate analysis indicated age, sex, and severity of neurological conditions as major determinants of the NHPQ scores.
This overall pattern of findings is peculiar to TOS and differs from the typical post-disaster nonspecific syndrome.
