Penetrating intracranial nail-gun injury to the middle cerebral artery: A successful primary repair.
Penetrating nail-gun injuries to the head are rare, however, the incidence has been gradually rising over the last decade. While there is a large volume of case reports in the literature, there are only a few incidences of cerebrovascular injury. We present a case of a patient with a nail-gun injury to the brain, which compromised the cerebral vasculature. In this article, we present the case, incidence, pathology, and a brief literature review of penetrating nail-gun injuries to highlight the principles of management pertaining to penetration of cerebrovascular structures. ⋯ To our knowledge, this is the first reported case of a vascular arterial injury to the MCA from a nail-gun injury. It is imperative to have a high clinical suspicion for cerebrovascular compromise in penetrating nail-gun injuries even when conventional imaging suggests otherwise.

Case Reports
Ruptured spinal arteriovenous malformation: Presenting as stunned myocardium and neurogenic shock.
Neurogenic pulmonary edema (NPE) is a clinical syndrome usually defined as an acute pulmonary edema occurring shortly after a central neurologic insult. NPE was identified 100 years ago, but it is still underappreciated in the clinical setup. NPE usually appears within minutes to hours after the injury. It has a high mortality rate if not recognized early and treated appropriately. Similarly, neurogenic shock is a known complication of spinal cord injury reported incidence is more than 20% in isolated upper cervical spinal injury. But NPE is rare to occur, and stunned myocardium (SM) is not reported in spinal arteriovenous malformation (AVM) rupture. SM is a reversible cardiomyopathy resulting in transient left ventricular dysfunction which has been described to occur in the setting of catecholamine release during situations of physiologic stress. We report a case of high spinal AVM rupture presenting as SM, NPE, and neurogenic shock. ⋯ Spinal AVM rupture can present as neurogenic shock, stunned myocardium, and pulmonary edema. Early recognition of AVM rupture and prompt surgical intervention, as well as aggressive treatment of shock, may enhance recovery and decrease the long-term morbidity.

The perplexing mystery of why so many trephined skulls from the Neolithic period have been uncovered all over the world representing attempts at primitive cranial surgery is discussed. More than 1500 trephined skulls have been uncovered throughout the world, from Europe and Scandinavia to North America, from Russia and China to South America (particularly in Peru). Most reported series show that from 5-10% of all skulls found from the Neolithic period have been trephined with single or multiple skull openings of various sizes. ⋯ It is concluded that Dr. Prioreschi's cohesive explanation to explain the phenomenon is valid and that his intriguing hypothesis is almost certainly correct. In the opinion of this author, the mystery within an enigma has been solved.

Epidural steroid injections (ESI) in the lumbar spine are not effective over the long-term for resolving "surgical" lesions. Here, we present a patient with a massive L2-L3 lumbar disk herniation whose surgery was delayed for 4 months by multiple unnecessary ESI, resulting in a cauda equina syndrome. ⋯ Pain specialists performed multiple unnecessary lumbar ESI critically delaying spinal surgery for 4 months in this patient with a massive lumbar disk herniation who ultimately developed a cauda equina syndrome. Unfortunately, pain specialists (e.g., radiologists, anesthesiologists, and physiatrists), not specifically trained to perform neurological examinations or spinal surgery, are increasingly mismanaging spinal disease with ESI/variants. It is time for spine surgeons to speak out against this, and "take back" the care of patients with spinal surgical disease.

The transition from the International Classification of Disease-9(th) clinical modification to the new ICD-10 was all set to occur on 1 October 2015. The American Medical Association has previously been successful in delaying the transition by over 10 years and has been able to further postpone its introduction to 2015. The new system will overcome many of the limitations present in the older version, thus paving the way to more accurate capture of clinical information. ⋯ With the implementation deadline gradually approaching, spine surgery practices that include multidisciplinary health specialists have to anticipate and prepare for the ICD change in order to mitigate risk. Education and communication is the key to this process in spine practices.
