Time management practices for the dentist.

Many people have been trained from childhood up through dental or professional school to depend on others to structure their time.

Contact allergy to aziridine paint hardener.

A painter experienced an extensive dermatitis when exposed to a paint primer (undercoating) used to protect wood siding. The primer was an acrylic emulsion with a polyfunctional aziridine added as a self-curing cross-linker or hardener. The polyfunctional aziridine cross-linker was made by reacting propyleneimine with a polyfunctional acrylate, trimethylolpropane triacrylate (TMPTA).
