Review Case Reports
Predictive factors for craniopharyngioma recurrence: a systematic review and illustrative case report of a rapid recurrence.
Recurrence of craniopharyngiomas (CPs) represents a frequent and unpredictable incident. Rapid tumor recurrence within a few months after surgery has been rarely reported. Nondefinitive predictive factors for rapid CP recurrence have been identified to date. We have systematically analyzed the tumor factors that presumably influence in CP recurrence. ⋯ Reliable tumor markers that predict CP recurrence are still lacking. The CP features presumably related to a higher risk of its recurrence are thought to be a larger tumor size, a tight adherence to the hypothalamus, the presence of whorl-like arrays, and high Ki-67 and p53 levels.

Biography Historical Article
Iulius Casserius and the first anatomically correct depiction of the circulus arteriosus cerebri (of Willis).
The circulus arteriosus cerebri is the arterial anastomotic circle at the base of the brain, now better known as the circle or polygon of Willis. The British physician and anatomist Thomas Willis (1621-1675) was the first to demonstrate the physiologic function and observe the clinical significance of the circulus. It has been overlooked, however, that the first accurate depiction of the circulus was provided by the Paduan anatomist Giulio Cesare Casseri (Iulius Casserius) (1552-1616) in two engravings published posthumously in multiple formats, including the Tabulae anatomicae LXXIIX (1627). ⋯ Although previous authors have commented on Casserius's portrayal of the circulus arteriosus in Table 10 of Tabulae anatomicae LXXIIX, none have discussed Figure 2 of Table 9. This is important because whereas the anterior communicating artery complex is depicted clearly in one table, the accurate course of the posterior communicating arteries is shown in the other. Together, Tables 9 and 10 represent a sophisticated, sequential dissection, which deserves recognition as the first accurate portrayal of the arterial anastomosis at the base of the brain.

Randomized Controlled Trial Comparative Study
Early versus delayed endoscopic surgery for carpal tunnel syndrome: prospective randomized study.
To compare the effects of early versus delayed endoscopic surgery in patients with moderately severe carpal tunnel syndrome (CTS). ⋯ On the basis of this study, early endoscopic surgery is proposed in patients with moderately severe CTS.

The purpose of this study is to provide an institutional retrospective review of surgically treated brainstem cavernous malformations. ⋯ Our longitudinal experience has guided us to emphasize minimally invasive approaches during resection of the brainstem cavernous malformations, occasionally at the expense of achieving a complete resection, to improve patient outcomes.
