Use of fluorescein sodium-assisted intraoperative sample validation to maximize the diagnostic yield of stereotactic brain biopsy: progress toward a new standard of care?
In patients with contraindication to open resection, histological diagnosis is obtained through a stereotactic biopsy (SB). Missed diagnoses and sampling errors are important limitations of SB; therefore, various ways have been proposed to increase the diagnostic yield (DY). Intraoperative histopathology can obtain a DY exceeding 98% but with several drawbacks, namely prolonged operative times and logistic concerns. The objective of this study was to evaluate whether intraoperative validation of samples with fluorescein sodium can obtain a high DY with the same ease of use as standard SB. ⋯ Compared with standard nSB, fSB showed a significantly higher DY and similar surgical time and rate of complications. The ease of use, wide diagnostic spectrum, and low cost make fluorescein sodium preferable to other fluorophores. The present study strengthens the limited data in the literature indicating routine use of fSB. The proposed workflow suggests that fSB should be the standard of care for contrast-enhanced cases. Intraoperative histopathology should be limited to nonenhancing cases, and nSB should be avoided. Future prospective multicenter studies will be useful for further validation of our findings.

Simple wound closure compared with surgery for civilian cranial gunshot wounds.
A carefully selected subset of civilian cranial gunshot wound (CGSW) patients may be treated with simple wound closure (SWC) as a proactive therapy, but the appropriate clinical scenario for using this strategy is unknown. The aim of this study was to compare SWC and surgery patients in terms of their neurological outcomes and complications, including infections, seizures, and reoperations. ⋯ There were important clinically relevant differences between the SWC and surgery groups. SWC can be considered a safe and efficacious proactive therapy in a carefully selected subset of civilian CGSW patients.
