Fiber-Optic Intracranial Pressure Monitoring System Using Wi-Fi-An In Vivo Study.

Background: Continuous invasive monitoring of intracranial pressure (ICP) is essential in neurocritical care for surveillance and management of raised ICP. Fluid-based systems and strain gauge microsensors remain the current standard. In the past few decades, several studies with wireless monitoring were developed aiming to reduce invasiveness and complications.

Jules Bernard Luys: from a description of the subthalamic nucleus to hypnotism.

The authors review the role of Jules Bernard Luys in the discovery of the subthalamic nucleus (STN) over 150 years ago. The relationships between the STN and movement disorders, particularly hemiballismus and Parkinson's disease, are well known. The academic life of Jules Bernard Luys can be divided into two periods: a brilliant start as a neuroanatomist, culminating in the discovery of the STN, followed by a second period marked by a shift in his academic activity and an increased interest in topics such as hysteria, hypnotism and, eventually, esotericism.

Morphometric Study of the Internal Globus Pallidus Using the Robert, Barnard, and Brown Staining Method.

Background: The globus pallidus internus (Gpi) is a major target in functional neurosurgery. Anatomical studies are crucial for correct planning and good surgical outcomes in this region. The present study described the anatomical coordinates of the Gpi and its relationship with other brain structures and compared the findings with those from previous anatomical studies.

Morphometric Analysis of the Nucleus Accumbens Using the Mulligan Staining Method.

Background: There is a need to further anatomically describe the nucleus accumbens (NA), as there is a growing neurosurgical interest in this locus but a limited understanding of its structure. In this study, we evaluated quantitative NA parameters and spatial relationships with adjacent structures found in the telencephalon.

Methods: A total of 155 NA specimens from coronal sections and 3 NA specimens from transverse sections were stained using the Mulligan technique as modified by Barnard et al.

Patient satisfaction with temporal lobectomy/selective amygdalohippocampectomy for temporal lobe epilepsy and its relationship with Engel classification and the side of lobectomy.

Purpose: The aim of this study was to investigate not only the effectiveness of epilepsy surgery in improving seizure control but also patient satisfaction with the result of the procedure in a sample of patients operated on at a specialized epilepsy unit.

Methods: Patients with temporal lobe epilepsy who had undergone epilepsy surgery (temporal lobectomy/amygdalohippocampectomy) were interviewed in a standardized telephone survey about their satisfaction with the results of the surgery. The morbidity of the surgery was also analyzed retrospectively.

Patterns of neuroaxis dissemination of gliomas: suggestion of a classification based on magnetic resonance imaging findings.

Background: Local invasion is the hallmark of malignant glioma dissemination. Leptomeningeal dissemination, a serious complication of malignant gliomas, has been increasingly observed. To correlate the physiopathologic mechanisms and the magnetic resonance imaging patterns of neuroaxis dissemination, a classification of malignant glioma dissemination is proposed (Instituto de Neurologia de Curitiba Classification).

Syncope or epileptic fits? Some examples of diagnostic confounding factors.

Syncope is a condition often misdiagnosed as epileptic seizures. However, the differential diagnosis between both conditions can be quite difficult, even for well-trained physicians. Four cases of epilepsy and/or syncope are reported, to exemplify this situation.

[Comparative analysis of human brain slices with three different staining techniques].

Studying neuroanatomy at brain slices with gray matter staining techniques has several advantages. More often, the models described by Barnard, Robert and Brown, Mulligan, and Green are used. The aim of this study was to identify which of them achieves the best results on differentiation between the gray and the white matter.

[Cerebral and systemic venous thrombosis associated to prothrombin G20210 mutation: case report].

Cerebral venous thrombosis is a clinical condition of difficult diagnosis, and poor prognosis when treatment is not started early. There is a long list of causes, and hereby we describe a case associated to prothrombin G20210 mutation. A 53-year-old man, white, was admitted with status epilepticus.

Peritoneal dissemination from central neurocytoma: case report.

Objective: Central neurocytoma is a low grade tumor of neuroglial origin and a relatively new histological entity. Only a few cases have been reported and its biological behavior is still uncertain. Some cases have shown an aggressive behavior (local recurrence, malignant dedifferentiation or CSF dissemination) and challenged the initial view of its relative benignity.
