Summary
Hip arthroscopy is recognised as a highly effective means of treating joint disorders. The majority of complications associated with hip arthroscopy involve neurovascular traction injury. We report a relatively unusual complication of hip arthroscopy, extravasation of irrigation fluid into the retroperitoneal and intraperitoneal cavities, resulting in abdominal compartment syndrome.
We studied Joseph disease clinically and pathologically in two patients of Portuguese ancestry, but from different families. We found involvement of spinocerebellar tracts, Clarke's column, anterior horn cells, motor cranial nerve nuclei, and substantia nigra. One patient also had pallidosubthalamic and pontocerebellar degeneration with normal inferior olives. The second patient, a Joseph family member, had nerve cell loss in the subthalamic nucleus. The neostriatum appeared normal in both cases. The pigmented nuclei contained a few Lewy bodies. The almost identical pathology in two families support the hypothesis that Joseph disease is a genetic entity.
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.
