The data suggest that development of postnatal corneal transparency is associated with decreased keratocyte density and quiescence and the expression of TKT/ALDH1A1.
Primary hypertrophic osteoarthropathy is a rare genetic disorder related to failures in prostaglandin metabolism. Patients present with joint pain, limb enlargement, skin thickening and finger clubbing. Radiographs show characteristic periosteal reaction and thickening along the long bones. We present MRI and US findings in a child with the condition. Ultrasound showed echogenic tissue surrounding the long bones, presumably reflecting oedema and inflammatory tissue. Doppler sonograms demonstrated increased vascularity on the surface of some superficial bony structures.
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.
