    Abstract: Earthquakes in the past few thousand years have left signs of land-level change, tsunamis, and shaking along the Pacific coast at the Cascadia subduction zone. Sudden lowering of land accounts for many of the buried marsh and forest soils at estuaries between southern British Columbia and northern California. Sand layers on some of these soils imply that tsunamis were triggered by some of the events that lowered the land. Liquefaction features show that inland shaking accompanied sudden coastal subsidence at the Washington-Oregon border about 300 years ago. The combined evidence for subsidence, tsunamis, and shaking shows that earthquakes of magnitude 8 or larger have occurred on the boundary between the overriding North America plate and the downgoing Juan de Fuca and Gorda plates. Intervals between the earthquakes are poorly known because of uncertainties about the number and ages of the earthquakes. Current estimates for individual intervals at specific coastal sites range from a few centuries to about one thousand years.

    Abstract: Trigger digit is a common pathology encountered by hand surgeons, but there is a lack of evidence-based guidelines. We investigated the treatment preferences of hand surgeons and explored whether geographic location, type of residency training, or clinical experience is associated with differences in practice. Methods An online survey was distributed via email by the American Association for Hand Surgery to 615 members. The survey consisted of 17 questions related to conservative and operative management of trigger digits. Results One hundred thirty-nine unique responses were received (22.6 %). Geographic distribution of respondents encompassed the entire USA and was not associated with variations in practice. Of the respondents, 56.8 % were trained in orthopedic surgery while 37.4 % had plastic surgery training. In regards to duration of practice, 8.6 % were in practice for up to 5 years, 29.5 % for 6–15 years, 33.8 % for 16–25 years, and 28.1 % for more than 25 years. Notably, the great majority of respondents preferred corticosteroid injections for initial treatment. Those who were willing to give three or more injections prior to surgery were more likely to be plastic surgeons in practice for 16 years or more. A large minority of surgeons utilized splinting in their conservative management. Orthopedic surgeons were more likely to perform tenolysis during pulley release and more likely to use monitored anesthesia care. Conclusions Variation exists between the treatment algorithms of hand surgeons when managing a trigger digit. Some of these differences may be attributable to the type of training or the duration of clinical practice.
