Giant splenic artery mycotic aneurysm presenting with massive hematemesis.

We report a 40-year-old man with rheumatic heart disease who presented with abdominal pain for three weeks and hematemesis for 24 hours. CT scan showed a large splenic artery aneurysm without evidence of pancreatitis. Mycotic aneurysm due to infective endocarditis was considered and confirmed by echocardiogram, which showed aortic and mitral valve regurgitation and vegetations. He was managed successfully with coil embolization of the aneurysm and antibiotics.     

APOE epsilon3 gene transfer attenuates brain damage after experimental stroke.

Apolipoprotein E (apoE, protein; APOE, gene) is the major lipid-transport protein in the brain and plays an important role in modulating the outcome and regenerative processes after acute brain injury. The aim of the present study was to determine if gene transfer of the epsilon3 form of APOE improves outcome in a murine model of transient focal cerebral ischaemia. Mice received an intrastriatal injection of vehicle, a second-generation adenoviral vector containing the green fluorescent protein gene (Ad-GFP) or a vector containing the APOE epsilon3 gene (Ad-APOE) 3 days before 60 mins focal ischaemia. Green fluorescent protein expression was observed in cells throughout the striatum and subcortical white matter indicating successful gene transfer and expression. ApoE levels in the brain were significantly increased after Ad-APOE compared with Ad-GFP or vehicle treatment. Ad-APOE treatment reduced the volume of ischaemic damage by 50% compared with Ad-GFP or vehicle treatment (13+/-3 versus 29+/-4 versus 27+/-5 mm(3)). The extent of postischaemic apoE immunoreactivity was enhanced in Ad-APOE compared with Ad-GFP or vehicle treated mice. These results show the ability of APOE gene transfer to markedly improve outcome after cerebral ischaemia and suggest that modulating apoE levels may be a potential strategy in human stroke therapy.     

Medical care for institutionalised elderly people in Singapore

Abstract: This study examined physical and financial arrangements for medical care of institutionalised elderly people in Singapore. Chief administrators of all long-term care facilities were interviewed on the existing arrangements for medical care of their residents. Results showed that 66 out of a total of 68 (97%) homes arranged medical care for residents. Of those, 29 homes offered on-site medical care with alternative arrangements when the in-house facilities were not operating. While government-owned homes would pay for all medical costs incurred by their residents, over 48% of voluntary homes and 87% of commercial homes required residents to be financially responsible for their care. The availability of financial support given to residents for payment of medical care was found to be associated with the type of sponsorship of the homes. While there was adequate physical access to medical care, the lack of financial support would pose a potential barrier to use of medical care for institutionalised elderly people.
