Brain hemorrhage: assessing outcome after subarachnoid hemorrhage.
A meta-analysis of results from the oxford vascular study indicates that rates of mortality associated with subarachnoid hemorrhage have decreased over the past 30 years. The study does not, however, address whether day-to-day functioning and quality of life in subarachnoid hemorrhage survivors have improved over the same time period.

ReviewHyperglycemia in acute ischemic stroke: pathophysiology and clinical management.
Patients with acute ischemic stroke frequently test positive for hyperglycemia, which is associated with a poor clinical outcome. This association between poor glycemic control and an unfavorable prognosis is particularly evident in patients with persistent hyperglycemia, patients without a known history of diabetes mellitus, and patients with cortical infarction. To date, however, only one large clinical trial has specifically investigated the effect of glycemic control on stroke outcome. ⋯ Here we review the available evidence linking hyperglycemia to a poor clinical outcome in patients with ischemic stroke. We highlight the pathophysiological mechanisms that might underlie the deleterious effects of hyperglycemia on acute stroke prognosis and systematically review the literature concerning tight glycemic control after stroke. Finally, we provide directions on the use of insulin treatment strategies to control hyperglycemia in this patient group.

Case ReportsEncephalopathy, visual disturbance and hearing loss-recognizing the symptoms of Susac syndrome.
A 23 year-old female presented to a neurology department with a 3 year history of recurrent episodes involving hearing loss, encephalopathy, focal neurological deficits, and visual field deficits. In the 3 years before presentation, the patient had been treated with methylprednisolone for suspected acute demyelinating encephalomyelitis and peripheral otogenic dysfunction from which she made a complete recovery, and for a visual defect in both eyes caused by bilateral branch retinal arterial occlusion, from which she partially improved and commenced long-term treatment with acetylsalicylic acid. ⋯ Long-term immunosuppressive treatment with azathioprine (150 mg/day) and prednisolone (10 mg/day), and inhibition of thrombocyte function with acetylsalicylic acid (100 mg/day).

Review Case ReportsA case of postpartum cerebral angiopathy with subarachnoid hemorrhage.
A 33-year-old woman experienced a thunderclap headache immediately postpartum. The headache recurred over the next 10 days, and the patient also developed generalized tonic-clonic seizures. A subarachnoid hemorrhage was demonstrated on a head CT scan. ⋯ NSAIds and opioid analgesics administered on postpartum day 3 provided partial headache relief. The next day, a blood patch was performed and intravenous caffeine, fluid and opioid analgesia were given to treat a suspected dural puncture headache. Following diagnosis of postpartum cerebral angiopathy on postpartum day 10, nimodipine was initiated to treat the vasospasm, and the headache was treated with opioid analgesics and toradol, followed by naproxen. The patient also received a 3-day course of intravenous magnesium sulfate.
