VRI generally occurs at day 10, mainly because of Gram-positive cocci, after a cerebrospinal fluid leak. Skin microbiota and biofilm seem to play a major role in VRI pathogenesis. Colonization of external ventricular drain by biofilm is universal and occurs quickly after catheter insertion. However, pathogens from the skin are more often associated with VRI than commensal bacteria. A review of proposed preventive measures shows that none has proven to be fully efficient. Periprocedural and prolonged systemic prophylactic antimicrobials have not shown to prevent VRIs and may promote the emergence of more resistant or pathogenic strains. Antimicrobial and silver-impregnated external ventricular drains, although promising, have not demonstrated preventive effects and may modify bacterial ecology. These results are consistent with the proposed pathophysiology. Finally, we will present a few propositions for future research that may help in improving our knowledge and thus better prevent VRIs.

To the authors' knowledge, this is the first study to conduct a meta-analysis of the current literature to assess if it is worth preserving the stalk during craniopharyngioma surgery or it is justified to sacrifice it.METHODSPubMed, Web of Science, and Embase databases were searched for craniopharyngioma studies till December 2021 that directly compared the endocrine sequelae of stalk sacrifice vs preservation in their patients. Odds ratio (OR) with 95% CI was used through fixed- and random-effects models.RESULTSFourteen studies with a total of 2074 patients met our inclusion criteria. The stalk was preserved in 925 patients (44.6%), was sacrificed in 1053 patients (50.8%), and was not identified intraoperatively or partially preserved, or the authors did not mention enough data for 96 patients (4.6%). Our study found that sacrifice of the pituitary stalk was associated with a significantly increased risk of endocrine dysfunction at the last follow-up (OR = 6.69, 95% CI = 3.36-13.35, P < .0001); however, it was not associated with a significant decrease in the risk of recurrence/progression of the disease (OR = 0.80, 95% CI = 0.60-1.06, P = .13).CONCLUSIONPituitary stalk sacrifice significantly increased the risk of postoperative endocrine dysfunction without reducing the risk of progression or recurrence of craniopharyngioma.

The aim of this study was to evaluate the long-term outcomes of SRS for NFPAs.METHODSWe conducted a retrospective review of 178 patients with NFPAs who received Cyberknife radiosurgery at a single institution between February 2008 and July 2021. Long-term outcomes of tumor control, new-onset hypopituitarism, and new visual disorders were assessed.RESULTSDuring a median radiological follow-up of 49.7 months (range, 2.5-158.1 months), only 11 (7.0%) patients experienced tumor progression.
