Chronic pain is a major health problem in developed countries where it may affect as much as 20% of the adult population. There have been no significant clinical breakthroughs in therapeutic options for persons with chronic neuropathic pain. ⋯ We found that affective and cognitive aspects of pain constitute important considerations in achieving improvements in the outcomes of pain neuromodulation in patients with chronic neuropathic pain. Based on our review, we propose that future novel neuromodulatory therapeutic strategies should be directed at areas in the brain that are involved in the neural mechanisms of reward valuation and appetitive motivation such as nucleus accumbens, ventral tegmental area, and prefrontal cortex.

In patients who undergo neurovascular stent placement with postoperative dual antiplatelet therapy to prevent in-stent thrombosis, there is no protocol for balancing the risk of acute stent thrombosis and bleeding if urgent neurosurgical procedures are required. We detail perioperative management of dual antiplatelet therapy in a 66-year-old man with a dolichoectatic aneurysm of the basilar artery treated with a Pipeline stent. Postoperatively, the patient was placed on aspirin and clopidogrel to prevent in-stent thrombosis. ⋯ The patient tolerated shunt placement without excessive bleeding or hemorrhagic complications. During the remainder of his hospital course, no evidence of stent thrombosis or intracranial hemorrhage was noted. We conclude that management of antiplatelet prophylaxis for neurovascular stent thrombosis in patients requiring urgent neurosurgical procedures may be successfully achieved by bridging aspirin and clopidogrel with ibuprofen and eptifibatide in the preoperative period.

Extra-axial fluid collections following decompressive craniectomy have been observed in a variety of patient populations. These collections have traditionally been thought to represent extra-axial signs of hydrocephalus, but they often occur even in settings where hydrocephalus has been optimally treated. This study aims to elucidate the phenomenon of extra-axial fluid collections after decompressive craniectomy in patients with treated hydrocephalus, in order to improve identification, classification, prevention and treatment. ⋯ In these patients, the term "external hydrocephalus" does not appropriately capture the relevant pathophysiology. Instead, we define a new phenomenon, "Craniectomy-associated Progressive Extra-Axial Collections with Treated Hydrocephalus" (CAPECTH), as progressive collections despite aggressive cerebral spinal fluid (CSF) drainage. Our data indicate that early cranioplasty can help prevent the formation and worsening of this condition, presumably by returning normal CSF dynamics.

Decompressive craniectomy (DC) is used for the management of refractory raised intracranial pressure, but the impact of DC on surgical outcome is still controversial. We report a 21-year-old man admitted to our hospital after a road traffic accident. ⋯ After DC, he developed a brainstem hemorrhage. Recovery was, however, good.

Case Reports
Life-threatening neurovascular injuries associated with recreational use of "banana" boats.
Banana boat rides are a popular form of recreation worldwide. Recommendations that speed should not exceed 15 mph, passengers should wear protective gear, and an observer should be present on the towing boat are generally ignored. Medical personnel at tourist venues and general practitioners may not be attuned to the risk of serious injury. ⋯ In the first patient, medical management failed and endovascular treatment was required due to neurological deterioration. In patient two, anticoagulation therapy prevented embolic sequelae. Boat operators, passengers, and the medical personnel who are first to see these patients should be aware of the risk of arterial dissection to facilitate early detection of these potentially life-threatening injuries.
