Review Case Reports
Perimesencephalic subarachnoid hemorrhage triggered by hypoxic training during swimming.
Perimesencephalic subarachnoid hemorrhage is a rare neurologic condition of unclear etiology. Multiple mechanisms have been postulated as potential triggers, but none are universally accepted. ⋯ The occurrence of perimesencephalic subarachnoid hemorrhage during hypoxic training suggests that acute venous congestion may be a triggering factor. The increasing popularity of hypoxic training demands vigilance from health care providers.

Review Case Reports
The white cerebellum sign: an under recognized sign of increased intracranial pressure.
The "white cerebellum" sign is a rare imaging finding described mainly in children with hypoxic brain injury. ⋯ The white cerebellum sign is a subtle imaging finding seen in patients with diffuse cerebral edema, such finding may not be as ominous as previously thought.

Review Historical Article
Hyponatremia and brain injury: historical and contemporary perspectives.
Hyponatremia is common in neurocritical care patients and is associated with significant morbidity and mortality. Despite decades of research into the syndrome of inappropriate antidiuretic hormone (SIADH) and cerebral salt wasting (CSW), their underlying pathophysiological mechanisms are still not fully understood. ⋯ Potential treatments for hyponatremia include mineralocorticoids and vasopressin 2 receptor antagonists, but further work is required to validate their usage. Ultimately, a greater understanding of the pathophysiological mechanisms underlining hyponatremia in neurocritical care patients remains our biggest obstacle to optimizing patient outcomes in this challenging population.
