Headache is one of the major clinical presentations in pediatric Moyamoya disease. However, the clinical features and underlying mechanisms are not fully understood. This study aimed to clarify the clinical feature of headache in pediatric Moyamoya disease and the effect of surgical revascularization. ⋯ These findings strongly suggest that disturbed cerebral hemodynamics may play key roles in developing severe headache in pediatric Moyamoya disease. STA-MCA anastomosis and encephalo-duro-myo-arterio-pericranial synangiosis may be effective procedures to rapidly resolve headache by widely supplying collateral blood flow to the operated hemispheres.

Neurosurgery is a challenging and stressful field. Excessive stress and professional dissatisfaction can lead to medical errors, negatively impact patient care, and cause physician burnout. Our objective is to develop and critically evaluate a survey measuring professional stress and satisfaction and to obtain preliminary data on sources and degree of stress and the prevalence of burnout among American neurosurgeons. ⋯ Our survey was well received and, according to respondents, encompassed the major issues associated with career stress, satisfaction, and burnout but needs to be shortened. Respondents were generally satisfied with their career but identified several major stressors. A larger study to identify predictors of career satisfaction/dissatisfaction will help generate dialogue on improving the quality of professional life for neurosurgeons.

Evolution and rebirth of functional stereotaxy in the subthalamus.
The first human stereotactic surgery based on intracerebral landmarks and Cartesian coordinates was performed in 1947. With this followed the publication of a number of stereotactic frames and atlases. The intercommissural line joining the anterior and posterior commissures was to define stereotactic coordinate systems used in movement disorders and other functional neurosurgical procedures. ⋯ With advances in understanding of the functional anatomy of the corticobasal ganglia circuit, advances in brain imaging, more sophisticated electrophysiologic recordings, and the use of deep brain stimulation as a reversible lesion, stereotactic surgery returned as a viable option for the treatment of movement disorders. The posterior medial part of the globus pallidus, ventral intermediate nucleus of the thalamus, and the subthalamus, its nuclei and pathways, are sites for interrupting pathophysiologic circuits. Not only has this been applied to movement disorders, but to epilepsy, chronic pain, and behavioral disorders.

Chronic subdural hematoma (CSDH) after aneurysmal clipping is a rare complication, but its incidence and risk factors are not known in detail. We retrospectively reviewed our cases requiring surgery for CSDH after clipping. ⋯ In addition to the classic risk factors, this study showed that clipping for unruptured aneurysms carries a higher risk for CSDH compared to ruptured aneurysms. We suggest that an increase of SFC during 1 week postoperatively can be a factor in predicting CSDH after clipping.

Chronic subdural hematoma is a common presentation to the neurosurgical practice that tends to occur among the elderly. ⋯ Without a heightened clinical suspicion, a similar presentation could be missed, resulting in delayed management.
