IOL is believed to be a more common benign intraosseous lesion within the skull base than previously reported. Cortical bone thinning and other features normally suggestive of aggressive pathology commonly occur. Otolaryngologists should be aware of these common lesions to avoid unnecessary further investigation.
To our knowledge, this is the first reported case of cochlear implantation carried out after selective vestibular nerve section. Given recent advances in cochlear implantation, this case indicates that it is essential to make every effort to spare the cochlear nerve if vestibular nerve section is required. If hearing loss occurs after vestibular nerve section, magnetic resonance imaging should be undertaken to establish whether the cochlear nerve is intact.
Cytomegalovirus (CMV) is a recognized cause of biliary abnormalities in acquired immune deficiency syndrome (AIDS) patients. In a prospective trial, two of 25 (8%) of AIDS patients on treatment for CMV related infections without biliary symptoms were found to have biliary dilatation on ultrasound. The study confirms previous findings of the poor correlation of sonographic findings with clinical status and biochemical profiles, and demonstrates that biliary tree dilatation in this group of patients may not per se warrant further invasive investigation.
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.
