Early results of postoperative fractionated stereotactic radiotherapy (FSRT) for functional and nonfunctional pituitary adenomas appear promising, but the majority of available evidence draws from small series with insufficient follow-up data to draw meaningful conclusions. ⋯ EBRT, external beam radiotherapyFSRT, fractionated stereotactic radiotherapyOR, odds ratioPTV, planning target volumeSRS, stereotactic radiosurgery.

The brainstem is one of the most challenging areas for the neurosurgeon because of the limited space between gray matter nuclei and white matter pathways. Diffusion tensor imaging-based tractography has been used to study the brainstem structure, but the angular and spatial resolution could be improved further with advanced diffusion magnetic resonance imaging (MRI). ⋯ CN, cranial nerveCPT, corticopontine tractCST, corticospinal tractCTT, central tegmental tractDLF, dorsal longitudinal fasciculusHCP, Human Connectome ProjectML, medial lemniscusMLF, medial longitudinal fasciculusRST, rubrospinal tractSTT, spinothalamic tract.

Postamputation pain is a debilitating condition that affects almost 60% of transfemoral amputees. Recent appreciation for the contribution of peripheral nerve derangement to the development of postamputation pain has resulted in focus on the role of nerve reconstruction in preventing pain after amputation. ⋯ CPN, common peroneal nervePAP, Postamputation painPLP, phantom limb painPS, phantom sensationsRLP, residual limb painTN, tibial nerve.

Occlusions of the M2 segment of the middle cerebral artery may cause significant clinical effects, especially when occurring in the dominant cerebral hemisphere, yet endovascular treatment of these lesions remains controversial. ⋯ ADAPT, direct aspiration first-pass techniqueECASS, European-Australasian Cooperative Acute Stroke StudyICH, intracranial hemorrhageIMS, Interventional Management of StrokeMERCI, Mechanical Embolus Removal in Cerebral IschemiamRS, modified Rankin ScaleNIHSS, National Institutes of Health Stroke ScalePROACT, Prolyse in Acute Cerebral ThromboembolismTICI, Thrombolysis in Cerebral Infarctiont-PA, tissue-type plasminogen activator.
