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.

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.

Our study seeks to assess the incidence of aspiration and prolonged dysphagia needing enteral feeding at discharge (EFD) in adults after posterior fossa (p-fossa) surgery. ⋯ Although 27% patients had EFD after p-fossa surgery, only 5/56 (9%) required continued enteral feeding. Aspiration, age, and lateral surgical approach is associated with EFD. In patients who demonstrate aspiration, we recommend placement of enteral feeding tube. Although most will not require continued enteral feeding at follow-up, longer follow-ups are needed.

Scythian trepanations in the Gorny Altai in Hippocratic times: modern expert appraisal of ancient surgical technologies.
To report the analysis of 3 cases of ancient trepanation discovered in the craniological collection (153 skulls) of the Pazyryk nomadic culture (500-300 bc) from the Gorny Altai, Russia, and to evaluate the technique, instrumentation, and materials used for cranial surgery as well as the motivation for the trepanations in Scythian times. ⋯ Our data suggest that the Scythian population of the Altai Mountains had sufficient medical knowledge to perform sophisticated and successful manipulations on the human skulls. Scraping technique with bronze tools was quite effective for prevention of wound infection and resulted in a high survival rate after surgery. In the era of methicillin-resistant Staphylococcus aureus, it may be useful to consider some ancient surgical technologies.

Observational Study
Risk profile in extracranial/intracranial bypass surgery--the role of antiplatelet agents, disease pathology, and surgical technique in 168 direct revascularization procedures.
Cerebral revascularization procedures are a treatment option in moyamoya disease patients, but recent studies failed to show an immediate benefit in cerebrovascular atherosclerotic disease. To facilitate optimal efficacy of the procedure, a detailed characterization of a representative perioperative complication rate and the role of potential risk factors such as underlying pathology, antiplatelet therapy, and the type of surgery performed is warranted and the purpose of this study. ⋯ Extra-/intracranial bypass surgery remains a treatment option in patients with moyamoya disease, although its use in the context of atherosclerotic disease was recently put into question. Regardless, a detailed characterization of perioperative risk factors is needed to optimize a potential long-term benefit of surgery. At a high-volume center, the complication rate is low independent from the underlying pathology with a high patency rate. Antiplatelet treatment does not increase the risk of hemorrhagic complications, but may improve outcome. Longer follow-up is required to adequately assess the true efficacy of revascularization on stroke prevention.
