A size-adjustable plate constructed of pure titanium is proposed for use in the reconstruction of the sella turcica. The plate is composed of two semicircular pieces that are connected by a hinge located at the top of the plate. Using an applicator, the plate is inserted into the sella turcica in a closed position. The same applicator is then used to open and secure the plate. The titanium causes minimal ferromagnetic artifacts on postoperative magnetic resonance imaging. Preliminary findings indicate a possible clinical use for this plate in the reconstruction of the sella turcica when no suitable piece of bone is available.
Diffusion-weighted imaging (DWI) may detect hyperintense lesions in patients with transient hypoglycaemia-induced hemiparesis or coma, which are completely reversible after glucose infusion.1(-)3 In vivo animal studies have documented the visualisation of such hypoglycaemia-induced changes of signal intensity and the reversal by glucose intake in detail.4 However, the time necessary for hyperintense lesions on DWI to disappear after glucose infusion in humans is still unclear. A 54 year old woman presented comatose with brain stem signs and severe hypoglycaemia. DWI demonstrated hyperintense lesions in the corpus callosum and internal capsules. She was treated with IV glucose. These lesions had resolved significantly on imaging 2 hours later and completely resolved on repeat imaging 2 days later. This report documents the time course of recovery of neurological lesions induced by hypoglycaemia after treatment with IV glucose.
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.
