In their April 1993 entries, the Shelleys encountered the dermatologic robin of springtime: pityriasis rosea. They traveled to Tulsa, Oklahoma, for the Oklahoma Dermatological Society meeting where Dr. Walter B. Shelley shared the techniques he used to resolve a patient's hive problem: "listen, teach, listen again, and challenge." Dr. E. Dorinda Shelley followed with her talk on how "modern antibacterial, antifungal, and antiviral drugs have brought new proof for the truth of focal infection as a significant cause of skin disease." Later the Shelleys attended the Michigan Dermatological Society Meeting with their visitor, Dr. Enrico Ceccolini (Bologna, Italy), and listened to lectures on skin cancer and early lime disease. They also shared the excitement from a mother of a 17-year-old patient with vitiligo who experienced repigmentation thanks to the Shelleys' treatment regimen.
