Case Reports
Coma from worsening spontaneous intracranial hypotension after subdural hematoma evacuation.
Low cerebrospinal fluid volume is typically diagnosed in patients presenting with positional headaches. However, severe intracranial hypotension and brain sagging may cause orthostatic coma. We present a case that illustrates this uncommon presentation. ⋯ Evacuation of subdural fluid collections may be detrimental in patients with low CSF volume by exacerbating the intracranial hypotension. Extreme brain sagging may lead to anatomical distortion of the diencephalon and brainstem resulting in coma.

To describe the concept, implementation, patient characteristics, and preliminary outcomes of a Neonatal Neurocritical Care Service (NNCS) recently established at the University of California, San Francisco. ⋯ While specialized neurocritical care has improved outcomes in adult populations, longitudinal studies are needed to determine whether specialized neurocritical care services will also result in improved neurodevelopmental outcomes for newborns.

In a recent publication (Wijdicks et al. in Neurology 71(16):1240, 2008), apnea test safety during brain death determination was evaluated at a single tertiary care center. One major conclusion was that apnea testing was safe in hemodynamically compromised patients in most circumstances and rarely aborted. Determinants of apnea test completion failure are unknown. ⋯ Acute lung injury is common in patients undergoing brain death evaluation. Patients that failed completion of apnea testing tended to be younger, had significantly greater A-a gradients, and were more acidotic.

To examine if the metabolic distress after traumatic brain injury (TBI) is associated with a unique proteome. ⋯ Metabolic distress after TBI is associated with a differential proteome that indicates cellular destruction during the acute phase of illness. This suggests that metabolic distress has immediate cellular consequences after TBI.

Alcoholic hand rubs (AHRs) have been proven effective in preventing nosocomial infections, and healthcare authorities include AHRs use among quality-of-care criteria. Since the onset of the influenza A (H1N1) pandemic, AHRs have gained considerable popularity among the general public. ⋯ Whereas overdrinking in social settings (wine and liquor) leads to a gradual increase in blood alcohol levels, AHRs poisoning is usually characterized by a sudden massive alcohol load. The unusual nature of the alcohol source may lead to diagnostic wanderings. AHRs are currently available in bottles that facilitate the ingestion of large amounts. Unit-dose packaging or dispensing might decrease the risk of AHRs poisoning.
