This volume presents clinical and research aspects of medicine and social dimensions of healthcare. It is designed for an audience with interest in health and societal factors. It is in part autobiographical, based on different phases of the author's life in medicine over 50 years, who revisited cases and problems encountered as she worked in different countries, including South Africa, Scotland, England and North America. Essays encompass aspects of clinical medicine and aspects of research, particularly in genetics and genomic medicine. New information on the topic or disorder and current opinions and approaches to finding solutions are reviewed.
