To test the association between the use of scalp blocks for malignant brain tumor craniotomy and survival. This is a retrospective study conducted in a tertiary academic center. Demographic, intraoperative and survival data from 808 adult patients with malignant brain tumors was included in the analysis. ⋯ Patients with scalp block showed no significant reduction in intraoperative opioids. After adjusting for significant covariates, the administration of a scalp block was not associated with an increase in PFS (HR, 95%CI = 0.98, 0.8-1.2, p = 0.892) or OS (HR, 95%CI = 1.02, 0.82-1.26, p = 0.847) survival. This retrospective study suggests that the use of scalp blocks during brain tumor surgery is not associated with patients' longer survival.

Migration of the distal catheter of a ventriculoperitoneal shunt to the scrotum is a documented but rare event. We present a case in which a 13 month old infant with hydrocephalus had recurrent migration of the peritoneal catheter to the right scrotum associated with a developing hydrocele. The patient underwent two revision operations and the distal catheter was ultimately shortened. He later underwent bilateral inguinal hernia repairs.
