Lost and found: a 100-year-old educational neurosurgical film by Thierry de Martel, pioneer of French neurosurgery.
Exchanges in medical practice are necessary for training. The use of movies for promoting medical practice was introduced in the late 19th century. The authors analyzed an unidentified movie titled Trepanation for Rolandic Zone Tumor (Trépanation pour tumeur de la zone rolandique) stored at the Établissement de Communication et de Production Audiovisuelle de la Défense of the French Ministry of Armed Forces. ⋯ A publication from 1922 contained 14 pictures taken from the movie presented in this paper and referred to a movie directed in 1911 by Thierry de Martel. This is strong circumstantial evidence that the film was directed and the surgery was performed by Thierry de Martel at the Vercingétorix Clinic in Paris, France, in 1911 while using the technology of the Gaumont company. This is a contemporary testimony to what surgical practice was over a century ago, and it illustrates how movies were, and remain, a unique way to learn and teach medicine.

Multiple intravenous infusions versus a single infusion of mesenchymal stem cells in a rat model of cerebral ischemia.
Recent randomized clinical trials of a single infusion of mesenchymal stem cells (MSCs) for acute cerebral stroke revealed a limited functional recovery outcome. Conversely, animal studies suggest that multiple MSC infusions may enhance functional recovery by inducing neural plasticity, which indicates that a multiple-infusion approach might be effective for stroke treatment in humans. The objective of this study was to investigate whether multiple infusions of MSCs enhance functional outcomes during the acute phase of cerebral ischemia. ⋯ Multiple infusions of MSCs led to histological changes in the CC and neural tracts within the CC. These results indicate that multiple systemic infusions of MSCs had a greater beneficial effect in the acute phase of MCAO than a single standard or high-dose infusion of MSCs.

Endoscopic transorbital approach for resection of mediobasal temporal lesions using an optic radiation-sparing strategy.
The endoscopic transorbital approach (ETOA) has emerged as a promising minimally invasive technique for resection of lesions in the mediobasal temporal region (MTR) due to its potential to preserve the integrity of the optic radiation (OR). This study evaluated the safety and efficacy of ETOA using an OR-sparing surgical strategy for mediobasal temporal lesions. ⋯ The combined use of ETOA and OR tractography appears to be a feasible approach for resecting lesions involving the MTR, especially in the anterior segment. In the authors' experience, this surgical strategy enables maximal safe resection while minimizing the risk of postoperative visual dysfunction. Further studies with larger sample sizes are warranted to validate these findings and assess long-term outcomes.

Regional differences in reimbursement rates from Medicare, Medicaid, and FAIR Health across common procedures for neurological surgeons.
FAIR Health-a nonprofit, state-funded database-was created as an independent repository of healthcare claims paid data to address allegations of price fixing. Many insurers have forced physicians to negotiate payments based on Medicare rates, rather than utilizing FAIR Health. The authors' objective was to provide an overview of regional differences in reimbursement rates per several sample neurosurgical Current Procedural Terminology (CPT) codes and to compare Medicare, Medicaid, and usual, customary, and reasonable rates via FAIR Health rate estimates. ⋯ Inherent differences exist between cities and states, including median income, employment rates, and health coverage. Despite geographic cost practice indices for Medicare and state-specific production of Medicaid, Medicaid/Medicare reimbursement rates did not vary across regions but were consistently and significantly lower than FAIR Health estimates throughout the US. Locale-specific variation in FAIR Health may further indicate a better accounting of regional differences in cost of practice.
