In our cohort of JME patients, we could not reproduce the findings of frontal gray matter changes from previous studies, and we could not detect an fMRI correlate of previously reported differences in working memory in JME. The neuropsychological deficits may be attributed partially to antiepileptic medication. We conclude that structural and functional frontal lobe deficits in JME patients have to be interpreted with care. One reason for a variation between different cohorts may be the genetic heterogeneity of the disease.
After open repair of a contained rupture of a giant abdominal aortic aneurysm, the patient, a 67-year-old man, developed respiratory insufficiency, and his hemoglobin oxygen saturation dramatically decreased when his position was changed from supine to upright. Transesophageal echocardiography revealed platypnea-orthodeoxia syndrome due to a patent foramen ovale and subsequent right-to-left-shunting despite normal intracardiac pressures. After interventional patent foramen ovale closure, the patient could be separated from the respirator without difficulty.
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.
