Vertebral artery dissection (VAD) may uncommonly present as isolated headache. More rarely, it simulates classical headache syndromes, including migraine. We report a VAD mimicking status migrainosus.

Acute compartment syndrome is a time-sensitive diagnosis and surgical emergency because it poses a threat to life and the limbs. It is defined by Matsen et al (Surg Gynecol Obstet. 1978;147(6):943–949) as "a condition in which increased pressure within a limited space compromises the circulation and function of the tissues within that space." The most common cause of compartment syndrome is traumatic injury. ⋯ Patients who are elderly, have preexisting nerve damage, or have psychopathology may have an atypical presentation. This case highlights the first report of a 75-year-old woman who developed painless bilateral compartment syndrome in the absence of traumatic injury.

Observational Study
Community implementation of intravenous thrombolysis for acute ischemic stroke in the 3- to 4.5-hour window.
Intravenous (IV) tissue plasminogen activator (tPA) administration for ischemic stroke between 3 and 4.5 hours after onset was found to be safe and beneficial in the ECASS III trial. However, its use has remained controversial, and its benefit as applied in routine practice at community stroke centers is less well defined. ⋯ Our results show that the conclusions of the ECASS III trial can be applied to routine stroke treatment at a community center and that IV thrombolysis in the 3- to 4.5-hour window results in similar safety and efficacy functional outcome at 3 months compared with administration before 3 hours after onset.

A 40-year-old man with diabetes and seizure disorder was found at home unresponsive and "very hot to touch" by his father 40 minutes before emergency medical services arrival. His usual medications included topiramate, divalproex sodium, and rosiglitazone/metformin. Paramedics administered oxygen, intravenous fluids, and naloxone. ⋯ Laboratory studies revealed severe metabolic acidosis with acute renal failure and rhabdomyolysis. In spite of sedation, intubation, and aggressive cooling measures, the patient had cardiac arrest and died approximately 2 hours after arrival. Serum topiramate and valproate concentrations were within therapeutic ranges at 8.8 μg/mL (therapeutic 2-12) and 97 μg/mL (therapeutic 50-100), respectively.

Crush injury from debris, combined with hypoxia and water and food deprivation (combined crush injury), is common in industrial accidents and events such as earthquakes and terrorist attacks. Whether electrocardiographic changes are associated with combined crush injury is unclear. ⋯ The findings suggest that abnormal electrocardiographic changes were seen in rats after simulated combined crush injury and decompression and were slow to resolve.
