Postmortem examination of a child with osteodysplastia (Melnick-Needles syndrome) showed peculiar fibro-osseous tissue in the marrow cavity, with areas of bone constriction but no abnormality of endochondral ossification. Pectus excavatum and scalloping of the vertebral bodies were also present.
Serial erect roentgenograms of the gallbladder during oral cholecystography were taken in 50 patients before and after a fatty meal. In the presence of good opacification, layering of opaque and nonopaque bile was noted in most cases 2 hours after the fatty meal. The degree of layering was related to the extent of gallbladder contraction produced by the fatty meal and the degree to which the gallbladder refilled by the inflow of nonopaque liver bile. The layering phenomenon thus appears to be a manifestation of a normally functioning gallbladder and occurs when the gallbladder refills with fresh nonopaque bile.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
