This book provided 13 case studies for use in teaching epidemiology. The studies were arranged in four sections: cohort studies, case control and proportionate mortality studies, cross sectional studies, and surveillance and screening studies. Each section started with a description of the general study design. The case studies were based on actual epidemiologic studies and were written by the respective principal investigators. The case studies included a wide variety of disease outcomes, including spontaneous abortion, carpal tunnel syndrome, kidney dysfunction, cytogenetic changes, ischemic heart disease, dermatitis, chronic renal disease, and several types of cancer. Exposures considered included video display terminal use, repetitive hand wrist motion, heavy metal, carbon-monoxide (630080), diesel exhaust, lead (7439921), vinyl- chloride (75014), pesticides, solvents, silica (14808607), and acid mists. The book was intended to be used in general courses on epidemiology as well as in higher level courses on occupational epidemiology. Data sets were included for five of the case studies.
