Targeting the posterior subthalamic area for essential tremor: proposal for MRI-based anatomical landmarks.
Deep brain stimulation (DBS) of the posterior subthalamic area (PSA) is an alternative to thalamic DBS for the treatment of essential tremor (ET). The dentato-rubro-thalamic tract (DRTT) has recently been proposed as the anatomical substrate underlying effective stimulation. For clinical purposes, depiction of the DRTT mainly depends on diffusion tensor imaging (DTI)-based tractography, which has some drawbacks. The objective of this study was to present an accurate targeting strategy for DBS of the PSA based on anatomical landmarks visible on MRI and to evaluate clinical effectiveness. ⋯ Targeting of the PSA based on anatomical landmarks representable on MRI is reliable and leads to accurate lead placement as well as good long-term clinical outcome.

Biography Historical ArticleHarvey Cushing's craniopharyngioma treatment: Part 2. Surgical strategies and results of his pioneering series.
Harvey Cushing (1869-1939) developed pioneering surgical techniques for craniopharyngioma (CP) removal. This study exhaustively analyzes the pathological variables and surgical strategies that influenced Cushing's results in his entire series of CP patients. ⋯ Harvey Cushing's techniques and surgical philosophy varied substantially throughout his career. The experience he gained with this large CP series made him aware of the importance of limiting the extent of tumor removal and leaving untouched the tumor portion strongly adhered to the hypothalamus.

Fully endoscopic microvascular decompression for hemifacial spasm.
Hemifacial spasm (HFS) is characterized by involuntary tonic and/or clonic contractions of facial nerve muscles. Fully endoscopic microvascular decompression (E-MVD) for HFS has not been widely adopted. This paper aims to illustrate the safety and efficacy of the fully endoscopic technique for HFS treatment. ⋯ A fully E-MVD for HFS provides a safe and comprehensive view of the neurovascular conflict. Exclusive use of the endoscope in MVD is both safe and feasible in the treatment of HFS. Attention to lateral spread response monitoring remains an integral part of comprehensive neurosurgical management.

Daniel Ruge: the first neurosurgeon to serve as physician to the president.
The role of chief White House physician has traditionally been held by an individual with a background in a broad medical field, such as emergency medicine, family medicine, or internal medicine. Dr. Daniel Ruge, who served as the director of the Spinal Cord Injury Service for the Veterans Administration and was appointed during President Ronald Reagan's first term, was the first neurosurgeon to become the chief White House physician. ⋯ Dr. Ruge's actions after the assassination attempt on President Reagan resulted in the rapid, smooth recovery of the then-president. Daniel Ruge's background, his high-profile roles and heavy responsibilities, and his critical decision-making are characteristics that make his role in the history of medicine and of neurosurgery unique.
