We report a 47-year-old woman with progressive multifocal leukoencephalopathy (PML). She was a carrier of HTLV-I virus, and developed subacute right hemiparesis and marked motor aphasia. She had a malignant lymphoma in the left neck and basal cell carcinoma in the right inguinal region. ⋯ Since it has been reported that HTLV-I, as well as HIV, activates the JC virus promoter and its proliferation, the latent infection of HTLV-I in the central nervous system (CNS) in this case might have stimulated the JC virus proliferation, promoting lesion extension over the cerebral cortex. There have been only a few reports of broad decreases in CBF by SPECT in PML patients. Further MRI and SPECT studies on PML patients are therefore necessary to evaluate the significance of HTLV-I in promoting the JC virus infiltration into the CNS.

The purpose of this study was to determine factors that extend the length of hospital stay in patients with ischemic stroke in acute hospital. Clinical data of 462 consecutive patients with acute ischemic stroke were retrospectively researched. ⋯ Independent and significant factors associated with prolonged hospital stay were National Institutes of Health Stroke Scale score on admission (OR, 1.072: 95% CI, 1.021 to 1.125), transient ischemic attack (OR, 0.142: 95% CI, 0.021 to 0.966), any complications during hospital stay (OR, 7.975: 95% CI, 3.539 to 17.971) and interval between offer to discharge (OR, 1.441: 95% CI, 1.294 to 1.605). It was suggested that control of complication could decrease length of hospital stay in patients with ischemic stroke in acute hospitals.
