Not Your Average Mediastinal Mass: A Case of a Large Mediastinal Teratoma in a Patient With a History of Polio Disease.

Mediastinal masses can be challenging to the surgical team and anesthetic considerations vary according to the location, pathology, surgical approach, and patient comorbidities. We report the case of a 21 cm symptomatic intrathoracic teratoma in a postpartum patient with a history of poliomyelitis. Significant challenges were presented for anesthetic induction, potential extracorporeal membrane oxygenation, and the use of neuraxial pain techniques and neuromuscular blockade.

Epidural Anesthesia to Facilitate Organ Blood Flow During the First Penile Transplantation in the United States: A Case Report.

Regional anesthesia has been used to help create local sympathectomy and improve blood flow in plastic surgery procedures involving tissue grafts and flaps. However, anesthetic techniques that reduce systemic vascular resistance must be used with caution in patients with aortic stenosis (AS). Combined neuraxial and general anesthesia with careful titration of the local anesthetic dose can be a safe approach for patients with AS undergoing microvascular procedures.

Correlation of acute phase inflammatory and oxidative markers with long-term cognitive impairment in sepsis survivors rats.

Oxidative damage and inflammation occur early in the brain after sepsis and are resolved when long-term cognitive impairment occurs. There is no information of a direct relation between acute levels of brain inflammation and oxidative damage and long-term cognitive deficits. We hypothesized that higher levels of early oxidative damage and inflammation are followed by long-term cognitive deficits, and this is related to a decrease in the levels of brain-derived neurotropic factor (BDNF).

Extent of resection in patients with glioblastoma: limiting factors, perception of resectability, and effect on survival.

Object: The extent of resection (EOR) is a known prognostic factor in patients with glioblastoma. However, gross-total resection (GTR) is not always achieved. Understanding the factors that prevent GTR is helpful in surgical planning and when counseling patients.

Santiago Ramón y Cajal and Harvey Cushing: two forefathers of neuroscience and neurosurgery.

Objective: To summarize the extraordinary accomplishments, and the commonalities, between Santiago Ramon y Cajal and Harvey Williams Cushing.

Methods: Existing literature describing the lives and achievements of Ramón y Cajal and Cushing, as well as personal communication, and the surgical records of the Johns Hopkins Hospital, from 1896 to 1912, were reviewed.

Results: Both Ramón y Cajal and Cushing were men of unusually broad interests and talents, and these shared characteristics undoubtedly influenced the career paths and scientific investigations they pursued.

Insurance status and inequalities in outcomes after neurosurgery.

Objective: Little is known about socioeconomic differences in postoperative outcomes after neurosurgery. We assessed the relation between insurance status and postoperative complication risk, neurosurgical intensive care unit stay, and hospital stay after neurosurgery.

Methods: We collected data on 918 consecutive craniotomy or spine-related neurosurgical cases in patients at least 18 years of age at the University of Michigan Hospitals after April 2006.

Sex disparities in postoperative outcomes after neurosurgical intervention: findings from the UMEND project.

Background: Little is known about the relationship between sex and the risk of complications after neurosurgical intervention. Improved understanding of this relationship may assist clinicians in advising patients of the risks and benefits of neurosurgical intervention and managing their patients after surgery.

Objective: To determine the independent relationship between sex and morbidity after neurosurgical intervention.

Postoperative outcomes following closed head injury and craniotomy for evacuation of hematoma in patients older than 80 years.

Object: Advances in the management of trauma-induced intracranial hematomas and hemorrhage (epidural, subdural, and intraparenchymal hemorrhage) have improved survival in these conditions over the last several decades. However, there is a paucity of research investigating the relation between patient age and outcomes of surgical treatment for these conditions. In this study, the authors examined the relation between patient age over 80 years and postoperative outcomes following closed head injury and craniotomy for intracranial hemorrhage.
