Case ReportsComplete resection of a cavernous haemangioma of the optic nerve, the chiasm, and the optic tract.
The involvement of the optic nerve, the chiasma, and the optic tract by a cavernoma has been reported in only three patients. In all of them, a biopsy of the vascular lesion was obtained. ⋯ The vascular malformation of the optic pathways was completely removed via a pterional approach. This is the first reported instance of complete resection of a cavernoma involving the optic nerve, the chiasm, and the optic tract.

Effect of lactate therapy upon cognitive deficits after traumatic brain injury in the rat.
In previous studies, it has been shown that intravenous lactate therapy can improve brain neurochemistry, adenosine triphosphate (ATP) generation and outcome after traumatic brain injury (TBI) in rats. In this study, we examined: (1) four L-lactate concentrations to determine the optimal therapeutic dose post TBI in terms of cognitive function; (2) ATP production after TBI for the L-lactate concentration found to be the optimal dose; (3) the possible production of lactic acidosis with the highest L-lactate concentration tested. ⋯ This study indicates that the intravenous infusion of 100 mM L-lactate provided the optimal concentration of the substrate to ameliorate cognitive impairment, probably via the regeneration of ATP following TBI in rats.

Neuro-endoscopic management of intraventricular neurocysticercosis (NCC).
Various approaches including endoscopy have been used for the treatment of intraventricular and cisternal NCC. We present our technique of Neuro-endoscopic management of intraventricular NCC. ⋯ Neuro-endoscopic surgery is an effective treatment modality for patients with intraventricular NCC. It effectively restores CSF flow and is capable of removing cysts completely or partially from accessible locations causing mass effect. Partial removal or rupture of the cyst does not affect the clinical outcome of the patients.

Biography Historical ArticleA pioneering female neurosurgeon: Dr. Aysima Altinok.
This article will look at how one female neurosurgeon in Turkey made her mark in the field. In 1954, Dr. Aysima Altinok began her residency training in neurosurgery at Haydarpaşa Numune Hospital where the first official department of neurosurgery in Turkey had been founded five years earlier. ⋯ She was among the founders of the Turkish Neurosurgical Society in 1968 and was awarded the honour of "Medical Doctor of the Year in Turkey" by the Ministry of Health in 1990. On May 15, 1996, she was accepted as an honorary member of Turkish Society of Neurosurgery for her contributions to neurosurgery. For proving the capability of a woman as a neurosurgeon, her contribution to the world history of neurosurgery should be respected.

Novel application of computer-assisted cisternal endoscopy for the biopsy of pineal region tumors: cadaveric study.
Long-standing debate continues about the management and biopsy of pineal tumors because of their complex microsurgical anatomy and deep location. Inspired by the concept of biopsy under direct visualization in the absence of hydrocephalus, we explored the effectiveness of neuroendoscope outside of its traditional territory using a new minimally invasive technique, computer-assisted cisternal endoscopy (CACE), for the biopsy of pineal tumors. ⋯ CACE may be used to approach pineal lesions outside the cerebral ventricular system for biopsy or debulking. Continuous computer updates on the endoscope position allows its safe navigation in narrow spaces (e.g., cerebrospinal fluid cistern). Its success will await future surgical trials.
