THIS IS a report of pancreatic function and x-ray studies in patients with psoriasis, some of whom had associated bone and joint symptoms. The available methods used to determine pancreatic function are not as informative as one would desire. There are no reports in the literature on pancreatic function in psoriatics; therefore such a study was thought to be worth while even though the present methods of evaluating pancreatic function are not perfect. Even though the cases reported here are comparatively few, a deviation from the accepted normal surely would be detected if pancreatic function in psoriasis was markedly changed. The second study attempts to clarify the disputed question of whether or not there is such an entity as psoriatic arthritis. Many observers believe that arthritis accompanying psoriasis cannot be distinguished roentgenologically or clinically from rheumatoid arthritis, while others think that there is a specific psoriatic arthritis which can
