Advances in the Management of Craniopharyngioma: A Narrative Review of Recent Developments and Clinical Strategies.

Craniopharyngiomas (CPs) are rare intracranial tumors arising from remnants of Rathke's pouch. Despite their benign histology, CPs present considerable clinical challenges due to their tendency to exert mass effect and adherence to critical neurovascular structures. There remains no clear consensus on the most effective management of CPs.

Langerhans cell histiocytosis of the sella in a pediatric patient: case report with review of the literature.

Purpose: Langerhans cell histiocytosis (LCH) is a rare condition arising from the monoclonal expansion of myeloid precursor cells, which results in granulomatous lesions that characteristically express CD1a/CD207. We report a case of LCH in a 3-year-old male involving the sphenoid bone with extension into the sellar/suprasellar region.

Case Report: A 3-year-old male presented with progressively worsening headaches and associated night sweats, neck stiffness, and fatigue over the previous 4 weeks.

Traumatic atlantoaxial rotatory fixation in adults: a systematic review of published cases.

Atlantoaxial rotatory fixation (AARF) in adults is a rare and clinically challenging condition characterized by a spectrum of etiological factors, predominantly attributed to traumatic and inflammatory pathologies within the craniovertebral region. Trauma is the most frequently identified cause within the adult population, with the first case report published in 1907. This study aims to conduct a systematic review that addresses the clinical presentations and management strategies relating to traumatic atlantoaxial rotatory fixation in adults.

Traumatic Brain Injury: A Comprehensive Review of Biomechanics and Molecular Pathophysiology.

Traumatic brain injury (TBI) is a critical public health concern with profound consequences for affected individuals. This comprehensive literature review delves into TBI intricacies, encompassing primary injury biomechanics and the molecular pathophysiology of the secondary injury cascade. Primary TBI involves a complex interplay of forces, including impact loading, blast overpressure, and impulsive loading, leading to diverse injury patterns.

Combined intracranial Acriflavine, temozolomide and radiation extends survival in a rat glioma model.

Glioblastomas have been historically difficult to treat with poor long-term survival. With novel strategies focused on targeting hypoxia-inducible factor (HIF) regulatory pathways, recent evidence has shown that Acriflavine (ACF) can effectively target glioma invasiveness and recurrence. However, local delivery of ACF and its combinatory effects with Temozolomide (TMZ) and radiation therapy (XRT) have not yet been optimized.

Disulfiram and copper combination therapy targets NPL4, cancer stem cells and extends survival in a medulloblastoma model.

Background: Medulloblastoma (MB) is the most common brain malignancy in children, and is still responsible for significant mortality and morbidity. The aim of this study was to assess the safety and efficacy of Disulfiram (DSF), an FDA-approved inhibitor of Aldehyde-Dehydrogenase (ALDH), and Copper (Cu++) in human SSH-driven and Group 3 MB. The molecular mechanisms, effect on cancer-stem-cells (CSC) and DNA damage were investigated in xenograft models.

Preclinical efficacy of ribavirin in SHH and group 3 medulloblastoma.

Objective: Medulloblastoma, the most common pediatric brain malignancy, has Sonic Hedgehog (SHH) and group 3 (Myc driven) subtypes that are associated with the activity of eukaryotic initiation factor 4E (eIF4E), a critical mediator of translation, and enhancer of zeste homolog 2 (EZH2), a histone methyltransferase and master regulator of transcription. Recent drug repurposing efforts in multiple solid and hematologic malignancies have demonstrated that eIF4E and EZH2 are both pharmacologically inhibited by the FDA-approved antiviral drug ribavirin. Given the molecular overlap between medulloblastoma biology and known ribavirin activity, the authors investigated the preclinical efficacy of repurposing ribavirin as a targeted therapeutic in cell and animal models of medulloblastoma.

Repurposing the FDA-Approved Antiviral Drug Ribavirin as Targeted Therapy for Nasopharyngeal Carcinoma.

Nasopharyngeal carcinoma (NPC) is a squamous cell carcinoma with a proclivity for systemic dissemination, leading many patients to present with advanced stage disease and fail available treatments. There is a notable lack of targeted therapies for NPC, despite working knowledge of multiple proteins with integral roles in NPC cancer biology. These proteins include EZH2, Snail, eIF4E, and IMPDH, which are all overexpressed in NPC and correlated with poor prognosis.

Evaluating the Effects of Cerebrospinal Fluid Protein Content on the Performance of Differential Pressure Valves and Antisiphon Devices Using a Novel Benchtop Shunting Model.

Background: Hydrocephalus is managed by surgically implanting flow-diversion technologies such as differential pressure valves and antisiphoning devices; however, such hardware is prone to failure. Extensive research has tested them in flow-controlled settings using saline or de-aerated water, yet little has been done to validate their performance in a setting recreating physiologically relevant parameters, including intracranial pressures, cerebrospinal fluid (CSF) protein content, and body position.

Objective: To more accurately chart the episodic drainage characteristics of flow-diversion technology.

Biodegradable wafers releasing Temozolomide and Carmustine for the treatment of brain cancer.

Glioblastoma multiforme (GBM) has few clinically approved therapeutic regimens. One of these therapeutic options includes placing biodegradable wafers releasing BCNU (Gliadel®) into the tumor bed at the time of surgical removal of the tumor. Due to the significant benefit this polymer technology has had clinically, we have prepared wafers releasing Temozolomide (TMZ), an anticancer drug used systemically for treating GBM.

Sleep-disordered breathing and stroke: A relation to be considered.

Stroke is a leading cause of death and disability. Despite expensive and elaborative research in finding out mechanisms of interrelation between sleep-disordered breathing (SDB) and stroke, there is yet much attention to be given in stroke units worldwide to the prompt diagnosis and treatment of SDB in order to improve morbidity and mortality rates related with stroke. The preventive diagnosis and treatment of SDB reduce stroke rate and improves penumbra area in case of ischemic stroke.
