Intracranial surgery can be complex and high risk. Safety, ethical and financial factors make training in the area challenging. Head model 3-dimensional (3D) printing is a realistic training alternative to patient and traditional means of cadaver and animal model simulation. ⋯ The findings of this review indicate that those who practice surgery and surgical techniques on 3D-printed head models deem them to be valuable assets in cranial surgery training. Understanding how surgical simulation on such models affects surgical performance and patient outcomes, and considering cost-effectiveness, are important future research endeavors.

Review Historical Article
King Charles VIII of France's Death. From an unsubstantiated traumatic brain injury to more realistic hypotheses.
On April 7, 1498, Charles VIII, King of France, attended a game of palm in the ditches of the Château d'Amboise. The 27-year-old King suddenly collapsed and became comatose. He laid down, almost on his own, on a straw mat that was hastily arranged, and he died 9 hours later. ⋯ Many historical accounts of Charles VIII's life and death, including Italian ambassadors' letters, led us to reconsider the commonly held version and to propose an alternative hypothesis. We have concluded that Charles VIII had experienced an acute consciousness disorder with language impairment that could have been related to an epileptic condition secondary to neurosyphilis. We have discussed whether a more accurate diagnosis for the cause of death could be obtained by a pathological analysis of the King's remains.

Despite the growing incidence of traumatic brain injury (TBI) in Sub-Saharan Africa, there is yet to be a study to map the current burden of the disease on the continent. This scoping review aims to outline the literature on TBI. ⋯ There is an increased need for TBI research, education, and training in Sub-Saharan Africa. This will aid stakeholders in optimizing patient management and outcome.

Multicenter Study
A two-year outcomes and complications of various techniques of lumbar discectomy; A multicentric retrospective study.
Various techniques of performing lumbar discectomy are prevalent, each having its rationale and claimed benefits. The authors ventured to assess the perioperative factors, outcomes, and complications of each procedure and compare among them with 946 patients contributed by 10 centers and operated by experienced surgeons. ⋯ Although minimally invasive techniques have some advantages over the open techniques in the perioperative factors, all the techniques are effective and provide similar pain relief and functional outcomes at the end of 2 years. The various rates of individual complications provide a reference value for future studies.

A chordoma is a slow-growing, invasive neoplasm in the neuraxis that is thought to arise from notochordal cells. At 10-year follow-up, the average survival rate is 50%, though individual prognosis varies substantially. We aimed to provide a comprehensive overview of the genes and proteins expressed in these tumors and their prognostic value to facilitate prognostication for patients with chordoma. ⋯ Identification of molecular factors that are associated with survival contributes to better prognostication of patients with chordoma. Given the rarity of chordoma, often only univariate analyses can be performed. Robust multivariate analyses are scarcer but provide independently significant prognostic factors. The data presented in this review can aid in prognostication for the individual patient and facilitate the development of targeted therapies.
