The objective of this work is to report the feasibility and results of an institutional protocol for the application of an innovative biologically active hemoderivative autologous material, denominated leukocyte- and platelet-rich fibrin (L-PRF), in the reconstruction of endoscopic approaches to the sellar region. ⋯ L-PRF membranes offer characteristics that are superior to other techniques and products, mainly because of their role as biological promoters of tissue regeneration, their low economic cost, and immediate availability. However, it would be necessary to confirm these results in studies involving more patients.

Breaking Bad News to Patients with Intracranial Tumors: The Patients' Perspective.
Bad news refers to information that subjectively impedes a patient's future prospects. Patients with intracranial tumors potentially face numerous pieces of bad news. This study assessed the patients' perspective regarding the content of bad news, patients' preferences for the communication of bad news, and clinical consequences of mismatch of patients' communication preferences. ⋯ Communicating bad news to the patient with a brain tumor in a way that is appreciated by the patient is a complex and demanding endeavor for the treating physician. Meeting patients' needs not only requires the skills regarding the communication of cancer-related news but also accounting for the specific needs ascribable to the neurologic features of the disease (e.g., regarding neuropsychological impairment or neurosurgical treatment).

Autonomic nervous system dysfunction is a known entity in strokes involving insula. It causes significant morbidity and mortality. No study to date has demonstrated autonomic nervous system dysfunction in patients with insular glioma. This is an exploratory study to identify the subclinical autonomic dysfunctions in insular glioma. ⋯ Patients with insular gliomas have significant impairment of autonomic functions, with left insular glioma showing sympathetic dominance. Suppression of autonomic function is greater in those presenting with seizures.

Dural arteriovenous fistula (DAVF) at the petrous apex with pial arterial supplies possesses complicated angioarchitecture, associates with aggressive neurologic behaviors, and associates with high risk of complications. This study aimed to summarize our experience with this type of DAVF in the last 15 years. ⋯ Supratentorial draining direction may be a risk factor for venous ectasia and SAH in petrous apex DAVFs with pial arterial supplies. The feeding pial arteries appeared to be at risk of embolization-related hemorrhagic complication and are therefore suggested to be embolized first.

Pineoblastomas are rare, malignant embryonal tumors that have a relatively higher incidence and a poorer prognosis in children. Owing to the rarity of these tumors, there is a paucity of data on associated prognostic factors. We used the Surveillance, Epidemiology, and End Results (SEER) database to evaluate prognostic factors for pineoblastomas with the aim of improving tumor management. ⋯ Our results show that the impact of tumor extension is not defined. OS is better in older children treated by radiotherapy, and gross total resection also appears to result in increased survival. A nomogram was built to predict 1-, 3-, and 5-year OS for these patients.
