Angiogram-negative subarachnoid hemorrhage (anSAH) accounts for 15% of spontaneous SAH. Recent studies suggest the outcome and diagnostic yield in anSAH differ based on initial bleeding pattern. We present a single-center experience in managing patients with SAH and negative initial digital-subtracted angiogram (DSA). ⋯ The overall incidence of true aneurysms in patients with angiogram-negative SAH is low (2.9%). Initial bleeding pattern strongly correlates with diagnostic yield and clinical outcome. Diffuse bleeding pattern is associated with significantly higher diagnostic yield, more in-hospital complications, and worse clinical outcome. Patients with initial imaging characteristics other than diffuse pattern SAH developed few disease related complications, with the majority of in-hospital adverse events treatment related.

Although the benefits of mild therapeutic hypothermia (MTH) in selected patients after out-of-hospital cardiac arrest have been consistently demonstrated, no controlled trial of MTH in selected patients after in-hospital cardiac arrest (IHCA) has been published. We sought to assess the benefit of MTH after IHCA in patients meeting our institutions IHCA MTH inclusion criteria. ⋯ No difference in neurological outcome at discharge was detected in predominantly non-shockable IHCA patients treated with MTH. This finding, if confirmed with further study, may define a population of patients for whom this costly and resource intensive therapy should be withheld.

Intrathecal baclofen (ITB) is an effective and well-tolerated treatment for patients with severe spasticity. Intoxications are rare and usually iatrogenic, with reported intrathecal boluses varying between 0.050 and 30 mg. ⋯ This case demonstrates that even excessive doses of ITB can let the patients survive without sequelae if treated promptly and offensively. A pertinent problem during detoxification is the question of when to restart ITB to avoid drug withdrawal.

Nimodipine is the only medication shown to improve outcomes after aneurysmal subarachnoid hemorrhage (SAH). Preliminary theories regarding the mechanism by which it prevents vasospasm have been challenged. The acute physiologic and metabolic effects of oral Nimodipine have not been examined in patients with poor-grade SAH. ⋯ Despite CPP targeted therapy with vasopressor medication, oral Nimodipine was associated with a decrease in MAP and CPP. When Nimodipine administration was associated with a decrease in MAP, there were concomitant drops in P(bt)O(2) and CBF. These findings suggest that MAP support after oral Nimodipine may be important to maintain adequate CBF in patients with poor-grade subarachnoid hemorrhage.

Decompressive hemicraniectomy reduces mortality after space-occupying MCA infarction. Data on the general public's opinion toward interventions that can save lives but leave the survivors impaired are lacking. ⋯ Explaining complex medical situations to laypersons poses a major problem, particularly to those of old age. Only a minority favors life-saving medical interventions if survival is associated with deficits of unpredictable degree. The majority of persons does not favor intervention even if only moderate impairment is anticipated. Decompressive surgery may in fact be against the values of many individuals.
