Battle's sign is a classical clinical sign that has long been held to be synonymous with fracture of the basal skull. As such the presence of Battle's sign is a strong indicator that a basal skull fracture could be present in the head injured patient, as exemplified by its inclusion as a major risk factor in scoring systems designed to assess the likelihood of basal skull fracture. ⋯ We present a case that describes the occurrence of this classic clinical sign in an unlikely setting and, for the first time since it was described more than 120 years ago, re-examine the pathologic basis for its appearance.

The vast majority of patients with intracerebral hemorrhage (ICH) are admitted to an intensive care unit (ICU). Patients admitted to ICUs have a high risk of developing nosocomial infections, while complicating infection appears to be associated with a longer ICU stay. An increased length of ICU stay translates directly into increased costs. The aim of this study was to assess the impact of a complicating infection on the length of ICU stay in patients with ICH. ⋯ Complicating infection was an independent predictor of a prolonged ICU stay in patients with ICH.

Benzodiazepine treatment of life-threatening gamma-hydroxybutyrate (GHB) withdrawal is frequently unsatisfactory. Animal studies suggest strongly that treatment with GABA(B) agonists, such as baclofen, will be a more effective strategy. ⋯ Baclofen, a GABA(B) agonist, may be a useful agent in the treatment of severe GHB withdrawal.

Perihemorrhagic pathophysiology of spontaneous intracerebral hemorrhages (ICH) remains unclear. Recently, ischemic changes in the perihemorrhagic zone (PHZ) have been discussed as a potential source of secondary damage. In this study, we focussed on diffusion and perfusion characteristics of experimental ICH. ⋯ We demonstrated vasogenic edema and mild perfusion reduction in the PHZ above the ischemic threshold. The existence of a perihemorrhagic "penumbra" indicating critically ischemic tissue analogous to ischemic stroke is unlikely.
