An industy-wide pulmonary study of men and women manufacturing refractory ceramic fibers
Researchers conducted an industry-wide study to evaluate the respiratory health of workers manufacturing refractory ceramic fibers in the US between 1987 and 1989. Seven hundred and forty two employees provided occupational histories, completed questionnaire, and performed pulmonary function test. For men, there was a significant decline of forced vital capacity. For women, the decline was significant among non-smokers. The results reveal that sex differences may exist in response to occupational or environmental exposure.

A modified placement technique to improve retention of tetracycline-impregnated fibers
A technique for applying tetracycline-impregnated fibers to a periodontal pocket is described. Periodontitis is a gum infection that creates pockets in the gumline. The usual treatment is to insert a fiber in the pocket that is impregnated with tetracycline. However, the fiber falls out in up to 29% of patients. The technique described can reduce fiber loss to less than 4%.
