John R. Connon (1862-1931) was a photographer and inventor who lived in Elora, Ontario, Canada during a time of remarkable innovations in the medium of photography. In 1886, Connon began to develop one of the earliest cameras to be capable of a full 360-degree photographic panorama using a single exposure. His early dedication to the use of flexible roll film, introduced by the Eastman Dry Plate and Film Company in 1885, allowed Connon to invent a camera that was ahead of its time. Through an agreement with C. P. Stirn, of C. P. Stirn's Patent Photographic Concealed Vest Cameras, Connon's design was transformed into the Wonder panoramic camera, further inspiring a succession of full-circle panoramic cameras including the Kodak Cirkut cameras. This thesis explores the history of Connon and his invention while acknowledging the history of this little-known Canadian inventor’s important contribution to the history of photographic technology.

AbstractAnother congress of the World Society for Reconstructive Microsurgery (WSRM) this past year in Bologna was magnificent not just for the presentation of so many keynote lectures by the giants of our field nor the novel and innovative ideas shown by those who will someday follow in those footsteps, but by making all of us realize how many capable microsurgeons there are now practically everywhere in this world, doing incredibly important surgical management of challenges that previously were unmet and resulted in sheer devastation for so many of our patients. How much we are the same in our goals, aspirations, and abilities could not be overlooked, but it is amazing how much we also want to learn more together—each relying on the other. To do so, we must not forget our origins as we appropriately plan for the future. All this we philosophized in our WSRM panel on lower extremity reconstruction, while emphasizing on the surface the perforator flap that at the least today has caught everyone's attention. In this overview to follow, we once again tell two stories, starting with the beginnings of the concept of flaps in showing how the nomenclature has evolved over time according to our various surgical manipulations. Often overlooked, though, is a parallel timeline by the anatomists who have better elucidated the circulation to these flaps, where it will become obvious that often long ago the existence of perforators was recognized by them long before known by the surgeons. At least today, these two paths have at least temporarily intersected. Our pursuit of the “perforator” in the perforator skin flap has come full circle, following the course of the history of the flap itself—a pursuit of excellence.

Control Study

Between October 1984 and January 1985, the largest outbreak of Kawasaki syndrome reported to date in the continental United States (62 cases) occurred in the Front Range of the Rocky Mountains, extending from Colorado Springs, Colorado, to Cheyenne, Wyoming. Fifty-two (84%) of these Kawasaki syndrome patients lived in the Denver metropolitan area. A case-control study revealed that 16 (62%) of 26 Kawasaki syndrome patients compared with 10 (20%) of 49 matched control subjects had a history of exposure to shampooed (19%) or spot-cleaned (81%) rugs or carpets within 30 days of the Kawasaki syndrome onset date (odds ratio = 5, P < .01). The time of exposure to shampooed or spot-cleaned rugs or carpets for 9 of 10 Kawasaki syndrome patients who had a single exposure and for all 6 Kawasaki syndrome patients who had multiple exposures were clustered within an interval 13 to 30 days before the onset of illness. Although the reason for this unusually large outbreak remains obscure, it is the third in which a statistically significant association between Kawasaki syndrome and rug or carpet cleaning has been found.
