To study the association between the clinical examination and the radiological assessment of lumbar disc disease in patients with sciatica. ⋯ The positive correlation between disability status and imaging findings validates both assessment methods. Routine use of disability scores brings a useful contribution to the assessment of sciatica patients.

Endoscopes have been commonly used in transsphenoidal surgery to treat pituitary tumors, to compensate for the narrow surgical field. Although many navigation systems have been introduced for neurosurgical procedures, there have been few reports of navigation systems for endoscopic operations. This report presents our recently developed, endoscopic, augmented reality (AR) navigation system. ⋯ The endoscopic AR navigation system allows surgeons to perform accurate, safe, endoscope-assisted operations to treat pituitary tumors; it is particularly useful for reoperations, in which midline landmarks may be absent. We consider the AR navigation system to be a promising tool for safe, minimally invasive, endonasal, transsphenoidal surgery to treat pituitary tumors.

Blood vessel (BV) compression of the trigeminal nerve (Cranial Nerve [CN] V) is a common cause of trigeminal neuralgia (TN). High-resolution magnetic resonance imaging scans obtained during gamma knife radiosurgery (GKRS) in patients with TN may be used to analyze the BV-CN V relationship. Follow-up data from a large series of patients treated with GKRS for TN were used to provide information regarding the BV-CN V relationship and pain relief. ⋯ In patients who have not undergone previous surgery for TN, BV-CN V contact revealed by high-resolution magnetic resonance imaging may indicate a particularly favorable response to GKRS.

Review Case Reports
Cerebellar hemorrhage after spinal surgery: report of two cases and literature review.
Cerebellar hemorrhage remote from the site of surgery may complicate neurosurgical procedures. We describe our experience with two cases of cerebellar hemorrhage after spinal surgery and review the three cases previously reported in the literature to determine whether these cases provide insight regarding the pathogenesis of remote cerebellar hemorrhage. ⋯ Cerebellar hemorrhage must be considered in patients with unexplained neurological deterioration after spinal surgery. Dural opening with loss of cerebrospinal fluid has occurred in every reported case of cerebellar hemorrhage complicating a spinal procedure, supporting the hypothesis that loss of cerebrospinal fluid is central to the pathogenesis of this condition. Because remote cerebellar hemorrhage can occur after procedures with the patient in the supine, sitting, and prone positions, patient positioning seems unlikely to play a causative role in its occurrence.

Neurosurgery at the Catholic University in Rome was initiated by Gian Franco Rossi in 1969 and has gradually expanded since then. From the beginning, research has been regarded as an essential part of training and daily activities in the university's neurosurgery programs. The professional and research education of all faculty members includes at least 1 year abroad in a reputable neurosurgical center. ⋯ In 1999, Giulio Maira succeeded Dr. Rossi in directing the Institute of Neurosurgery and the Division of General Neurosurgery. In addition to the history of neurosurgery at the Catholic University in Rome, this article describes present challenges and plans for the future in neurosurgery at the university.
