Quality-of-Life Outcomes in Adults and Children With Chiari 1 Malformation and in Those Managed Without Surgery: A Prospective, Multicenter, Observational Study.

Background And Objectives: Chiari 1 malformation (CM1) is a common MRI finding and a frequent reason for neurosurgical consultation. Although many studies have investigated surgical outcomes for patients with CM1, outcomes for those treated without surgery have been less frequently reported. The UK Chiari 1 Study reports the quality of life of adults and children with CM1 treated without surgery, 12 months after the first neurosurgical clinic visit.

Clinical outcomes of adults with intracranial grade 1 and 2 ganglioglioma.

Ganglioglioma is a rare primary brain tumour that most frequently occurs in children and young adults. They are generally low-grade and have a favourable prognosis, but there is limited literature to guide the optimal management. The aim of this study was to investigate the clinical outcomes of adults with intracranial ganglioglioma, and to determine the frequency and duration of radiological follow-up.

Crossing the blood-brain barrier: emerging therapeutic strategies for neurological disease.

The blood-brain barrier is a physiological barrier that can prevent both small and complex drugs from reaching the brain to exert a pharmacological effect. For treatment of neurological diseases, drug concentrations at the target site are a fundamental parameter for therapeutic effect; thus, the blood-brain barrier is a major obstacle to overcome. Novel strategies have been developed to circumvent the blood-brain barrier, including CSF delivery, intracranial delivery, ultrasound-based methods, membrane transporters, receptor-mediated transcytosis, and nanotherapeutics.

Posterior-Transcallosal Approach to a Choroidal Fissure Arteriovenous Malformation: Video of Adapting a "Bridging Vein Free" Corridor to This Complex Region.

Choroidal fissure arteriovenous malformations (ChFis-AVMs) are uncommon and challenging to treat due to their deep location and pattern of supply. The choroidal fissure lies between the thalamus and fornix, from the foramen of Monroe to the inferior choroidal point. AVMs in this location receive their supply from the anterior, lateral posterior choroidal artery and medial posterior choroidal arteries and drain to the deep venous system.

Importance of Arachnoid Dissection in Arteriovenous Malformation Microsurgery: A Technical Note.

Intracranial arteriovenous malformations (AVMs) are congenital anomalies where arteries and veins connect without a capillary bed. AVMs are the leading cause of nontraumatic intracerebral hemorrhages in people younger than 35 years old. The leptomeninges (arachnoid and pia) form from the meninx primitiva.

Successful treatment of vancomycin-resistant enterococcal infection of an external ventricular drain with 2 weeks of intravenous linezolid.

Hydrocephalus is a common condition worldwide, and is frequently managed by diversion of cerebrospinal fluid (CSF), either externally with a drain or internally with a shunt. An external ventricular drain (EVD) can be an essential treatment modality, but is associated with a risk of infection, most commonly caused by species, which can result in meningitis or ventriculitis and a delay in the definitive management of the hydrocephalus. Here, we report the case of a patient who required an EVD to manage post-operative hydrocephalus following a craniotomy and microvascular decompression for trigeminal neuralgia.

Currarino syndrome: repair of the dysraphic anomalies and resection of the presacral mass in a combined neurosurgical and general surgical approach.

OBJECTIVEIt is well established that Currarino syndrome (CS) may be associated with spinal dysraphism. Here, the authors report on 10 CS patients with dysraphic anomalies who had undergone a combined neurosurgical and general surgical approach to repair the dysraphic anomalies and resect the presacral mass in a single operation. They discuss the spectrum of spinal dysraphism that may coexist in CS in the context of its developmental etiology.

Microtubules, polarity and vertebrate neural tube morphogenesis.

Microtubules (MTs) are key cellular components, long known to participate in morphogenetic events that shape the developing embryo. However, the links between the cellular functions of MTs, their effects on cell shape and polarity, and their role in large-scale morphogenesis remain poorly understood. Here, these relationships were examined with respect to two strategies for generating the vertebrate neural tube: bending and closure of the mammalian neural plate; and cavitation of the teleost neural rod.
