To conduct a quantitative analysis of published studies on hematoma enlargement after intracerebral hemorrhage. ⋯ This bibliometric analysis analyzed the research framework and hotspots on hematoma enlargement after cerebral hemorrhage, which can help researchers better understand this field and provide potential suggestions for collaborations and research.

To investigate how the expansion trajectory of a lateral expandable cage affects pressure distribution at the cage-endplate interface under well-controlled biomechanical loading conditions. ⋯ Of the cage designs evaluated in this study, an expandable cage with independently adjustable anterior and posterior heights lowered the maximum pressure measured at the cage-endplate interface and alleviated the potential of cage edge loading, both of which are important considerations that are fundamental for a successful fusion procedure and the mitigation of implant subsidence risk.

Exposure to neurosurgery is important for knowledge of neurosurgical conditions that physicians may encounter. The current status of neurosurgery nonsubinternship clerkships in the United States is unknown; this study determined the availability and format of non-subinternship neurosurgery clerkships in DO (Doctor of Osteopathic Medicine)-granting and MD (Doctor of Medicine)-granting U.S. medical schools. ⋯ Most U.S. medical schools provide elective neurosurgery non-subinternships. Fewer, although still a majority, of DO-granting schools offer a neurosurgery non-subinternship compared with MD-granting schools.

We examined the utility of passive high gamma mapping (HGM) as an adjunct to conventional awake brain mapping during glioma resection. We compared functional and survival outcomes before and after implementing intraoperative HGM. ⋯ Our results tentatively indicate that passive HGM is a safe and potentially useful adjunct to electrical stimulation mapping for awake cortical mapping, conferring at least comparable functional and survival outcomes with a nonsignificant lower rate of intraoperative epileptiform events. Considering the limitations of our study design and patient cohort, further investigation is needed to better identify optimal use cases for HGM.

A 64-year-old man presented with an 8-year history of decreased libido, impotence, and blurred vision. The neurologic examination revealed a mild left facial weakness, visual acuity of (20/60), and right homonymous hemianopia. Laboratory investigation of serum prolactin was 7896 ng/mL. ⋯ The histopathologic findings were compatible with prolactinoma. Invasive giant prolactinomas are defined as 1) tumor size of >4 cm in diameter; 2) serum prolactin of >1000 ng/mL; and 3) mass effect or hyperprolactinemia-induced symptomatology. The management of invasive giant prolactinoma commonly comprises a multimodal approach of both medical treatment and surgical intervention.
