Does Campylobacter jejuni infection elicit "demyelinating" Guillain-Barre syndrome?
Campylobacter jejuni enteritis is the most common antecedent infection in Guillain-Barré syndrome (GBS). C. jejuni-related GBS is usually acute motor axonal neuropathy (AMAN), but previous reports described many cases of the demyelinating subtype of GBS (acute inflammatory demyelinating polyneuropathy [AIDP]) after C. jejuni infection. ⋯ Patients with C. jejuni-related Guillain-Barré syndrome can show transient slowing of nerve conduction, mimicking demyelination, but C. jejuni infection does not appear to elicit acute inflammatory demyelinating polyneuropathy.

Intracranial arterial dolichoectasia and its relation with atherosclerosis and stroke subtype.

To protect the ischemic penumbra, guidelines have recommended against treating all but the severest elevations in blood pressure during acute ischemic stroke. ⋯ Most patients with acute ischemic stroke are treated with antihypertensive agents despite the absence of severe hypertension. Although low blood pressure is common among treated patients, frank hypotension is unusual.

Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized trial of frovatriptan for the intermittent prevention of menstrual migraine.
Menstrually associated migraine (MAM) is often prolonged and difficult to manage with conventional therapies. Frovatriptan is a new selective 5HT(1B/1D) receptor agonist indicated for short-term management of migraine. It has a long half-life and good tolerability. These characteristics suggest that frovatriptan may be useful for the intermittent prevention of MAM. ⋯ Frovatriptan given prophylactically for 6 days was effective in reducing the incidence of menstrually associated migraine. More than half of patients who used frovatriptan 2.5 mg BID had no menstrually associated migraine headache during the 6-day perimenstrual period. The findings are consistent with the long duration of action and good tolerability of frovatriptan observed in short-term migraine management.

Randomized Controlled Trial Multicenter Study Clinical Trial
Cooling for Acute Ischemic Brain Damage (COOL AID): a feasibility trial of endovascular cooling.
To report results of a randomized pilot clinical feasibility trial of endovascular cooling in patients with ischemic stroke. ⋯ Induced moderate hypothermia is feasible using an endovascular cooling device in most patients with acute ischemic stroke. Further studies are needed to determine if hypothermia improves outcome.
