Central nervous system (CNS) tumors are the most common cause of cancer-related death in children. Little is known about the demographics and treatment of pediatric brain tumors in low- and middle-income countries (LMICs). ⋯ We present the first operative series of childhood CNS tumors in Nepal. Children often had delayed diagnosis and treatment of a tumor, despite symptoms. More comprehensive data are required to develop improved treatment and management algorithms in the context of a given country's demographics and medical capabilities for childhood CNS tumors.

Julius Caesar's epilepsy: Was it caused by a brain arteriovenous malformation?
Julius Caesar (100-44 BC) was one of the most charismatic political figures in history. Best remembered for his military achievements, he was also a writer, historian, and statesman. ⋯ In this essay, we highlight the life of Julius Caesar, with emphasis on the potential origin of his sickness. Although a definitive diagnosis obviously cannot be made, as new published studies showed a possible cerebrovascular etiology, a new hypothetical diagnosis is presented.

Retractorless surgery for anterior circulation aneurysms via pterional keyhole approach.
Brain retraction is required during many intracranial procedures to provide more working space. However, it is difficult to avoid brain retraction injury. Here, we report on retractorless surgery for anterior circulation aneurysms via a pterional keyhole approach. ⋯ Furthermore, the proportion of brain retraction injuries in group I (5.3%) was lower than that in group II (34.6%). In addition, a better prognosis was obtained in patients who underwent retractorless surgery. With the careful and accurate use of a handheld suction device and operating instruments, the retractorless technique can replace fixed retraction, reduce brain retraction injury, and is applicable to surgeries on anterior circulation aneurysms via pterional keyhole approaches.

Direct factor Xa inhibitors rivaroxaban and apixaban are efficacious alternatives to warfarin and confer a lower risk of spontaneous intracranial hemorrhage (ICH); however, they lack a validated reversal strategy. We evaluated the efficacy and safety of 4-factor prothrombin complex concentrate (PCC) administration on rivaroxaban- and apixaban-mediated coagulopathy in patients with traumatic and spontaneous ICH. ⋯ Despite no studies demonstrating the efficacy of 4-factor PCC administration for reversal of coagulopathy in patients on direct factor Xa inhibitors, our early experience demonstrates it to be safe, yet potentially reducing hemorrhagic complications and hematoma expansion in this critically ill population.

Surgery is a well-established and safe treatment option for focal drug resistant epilepsy. However, difficulties are often encountered in diagnosing mesial cortical lesions. The aim of this study was to evaluate the usefulness and overall complication rate of subdural interhemispheric electrodes (IHEs) as part of an invasive presurgical evaluation of epilepsy patients. ⋯ Implantation of IHE for the preoperative evaluation of epilepsy patients is an established surgical procedure with an acceptable complication profile. The benefits delivered from IHE can positively influence final seizure outcome in the challenging group of extratemporal resections due to interhemispheric lesions. Thus IHEs demonstrate a useful diagnostic utility for the presurgical evaluation of selected epilepsy patients.
