Case-control design.<br />

Cases: 26 patients with histologically<br />

confirmed laryngeal carcinoma and no<br />

history <strong>of</strong> Pb exposure or toxicity.<br />

Controls: 53 patients with similar<br />

demographic pr<strong>of</strong>iles and no history <strong>of</strong><br />

cancer from the same hospital.<br />

Cohort design.<br />

468 Italian glass workers employed <strong>for</strong><br />

at least one yr between 1953 and 1967.<br />

Mortality among workers was tracked<br />

and cause <strong>of</strong> death was determined <strong>for</strong><br />

deceased workers. Standardized<br />

mortality ratios were computed <strong>for</strong><br />

workers vs. national population<br />

counterparts.<br />

Cohort design.<br />

1,741 male Sardinian Pb and zinc miners<br />

from two mines employed at least one yr<br />

between 1931 and 1971.<br />

Mortality traced through 1992 to<br />

determine cause <strong>of</strong> death.<br />

Mortality among miners was compared<br />

with age- and calendar-yr-specific<br />

regional rates to compute an SMR.<br />

Blood Pb levels and ALAD activity were<br />

measured.<br />

Workers producing low-quality glass<br />

containers were classified as Pb-exposed.<br />

All miners were considered to be exposed<br />

to Pb.<br />

Blood Pb levels were similar, but ALAD activity was<br />

significantly lower in cases than controls (Mean 50.79 U/L<br />

vs. 59.76 U/L, p < 0.01). No control <strong>for</strong> other risk factors.<br />

Potential distortion by effects <strong>of</strong> disease on Pb and/or<br />

ALAD parameters.)<br />
