Postconcussion syndrome (PCS) is usually underestimated in cases of mild head injury (MHI). It is one of the most common causes of physical, cognitive, and psychomotor disturbances that affect the quality of life, work, and social reintegration of individuals. Until now, we did not have evidence of structural abnormalities shown by traditional imaging methods. We describe a series of instruments that confirm PCS with satisfactory evidence. ⋯ This first diagnostic strategy supports with scientific evidence the presence of PCS in MHI. We identified physical and neuropsychological abnormalities from this group, affecting the areas of memory and learning. Evidence of neurometabolite disturbances were found specifically in the frontal lobe. It is necessary to complete comparative follow-up for an extended period of time. The neuropsychological and spectroscopy tests allow us to confirm the diagnosis of a syndrome that is usually neglected.

Comparative Study
Fully endoscopic interlaminar and transforaminal lumbar discectomy: short-term clinical results of 163 surgically treated patients.
To evaluate the clinical outcomes of patients with lumbar disc disease undergoing fully endoscopic surgery at a single clinic. ⋯ Fully endoscopic interlaminar or transforaminal surgeries are safe and effective treatment modalities for lumbar disc herniations. Despite the difficulties of acquiring this new technique, good results can be achieved with sufficient experience.

To report experience with 7 cases of intracranial aneurysms of the vertebral artery (VA) and its branches that were treated with occipital artery (OA)-posterior inferior cerebellar artery (PICA) bypass. ⋯ OA-PICA bypass with obliteration of the aneurysm is one of the optimal treatments for intracranial aneurysms that occur at the VA and its branches because it can preserve the perforators and distal blood flow from the PICA.

The role of laboratory dissection training in neurosurgical residency: results of a national survey.
Work hour restrictions and current quality, financial, and legal concerns have reduced resident operative volume and autonomy. Although laboratory (cadaveric or animal) dissection has a rich history in neurosurgery, its current role in resident training is unclear. Recent literature suggests educators have looked to simulation to accelerate the learning curve of acquiring neurosurgical technical skills. The purpose of this study was to determine the prevalence, characteristics, and extent of laboratory dissection in neurosurgical residency programs in the United States. ⋯ In neurosurgical resident education, laboratory dissection is widely used; however, significant variation exists. Nonetheless, program directors believe laboratory dissection plays an integral role in neurosurgical training and is currently associated with greater educational benefit than simulation.

This study was undertaken to evaluate de novo aneurysm formation in the long-term follow-up of patients with clipped aneurysms. ⋯ The risk of de novo aneurysm formation in patients with clipped aneurysms is significant in long-term follow-up. CT angiography can be used as a noninvasive method for detection of de novo aneurysms in these patients.
