In recent years, there has been an outpouring of scoring systems that were built to predict outcomes after various surgical procedures; however, research validating these studies in spinal surgery is quite limited. In this study, we evaluated the predictability of the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (ACS NSQIP SRC) for various postoperative outcomes after spinal deformity surgery. ⋯ The ACS NSQIP SRC is a poor predictor of outcomes after spinal deformity surgery.

Magnetic resonance-guided focused ultrasound (MRgFUS) has been increasingly performed in recent years as a minimally invasive treatment of essential tremor and tremor-dominant Parkinson disease. One of the side effects after treatment is dysgeusia. Some centers use tractography to facilitate the treatment planning. However, there have been no reports of identifying gustatory tracts so far. Our aim was to investigate the technical feasibility of isolating and visualizing the gustatory tracts, as well as to explore the relationship between the gustatory tract and the MRgFUS lesion using actual patient data. ⋯ The thalamic gustatory tracts can be reliably visualized using tractography.

Brain tumors have a poor prognosis and a high death rate. Sufficient aftercare is necessary to enhance patient results. But follow-up care provision is fraught with difficulties in low- and middle-income countries (LMICs), where a variety of variables can impede access to care. Therefore, our systematic review aimed to identify challenges to follow-up care for brain tumors and possible solutions in LMICs. ⋯ In LMICs, several issues pertaining to personnel, infrastructure, service delivery, financing, information management, and governance impede the provision of follow-up treatment for patients with brain tumors. As established by the suggested techniques found in the literature, addressing these issues will necessitate concurrent action by stakeholders, legislators, health ministries, and government agencies.

Vesalius and His Manikin: An Enduring Influence on Modern Anatomic Teaching.
Anatomic teaching has long informed surgical knowledge, experience, and skills. One tool for teaching that emerged during the Renaissance was the fugitive anatomic sheet, which used flap layers to reveal different levels of anatomy. In 1538, Vogtherr introduced the first fugitive sheets, which included illustrations of male and female figures with a torso paper flap that, when lifted, revealed the internal organs in a cartoonish style. ⋯ Vesalius's groundbreaking discoveries, his use of the most advanced printing techniques, and his innovative teaching style are fundamental aspects of the legacy of medical education. This article shows these remarkable fugitive anatomic sheets from the original publications of Fabrica and Epitome together for the first time. It explores the innovative concepts and applications of Vesalius's unique printings.

Appropriate correction relative to the age-adjusted sagittal alignment target reduces the proximal junctional failure (PJF) risk. Nonetheless, a considerable number of patients suffer from PJF despite optimal correction. The aim of this study was to identify the risk factors of PJF that occurs despite optimal correction relative to the sagittal age-adjusted score (SAAS) in adult spinal deformity surgery. ⋯ PJF developed in a considerable portion of patients despite optimal correction relative to the age-adjusted alignment. The risk factors of PJF in this patient group were high body mass index, high LDI exceeding 61%, and no use of hook fixation. PJF could be further decreased by properly managing these risk factors along with optimal sagittal correction.
