It remains unclear whether stereotactic radiosurgery (SRS) offers the same benefit for patients with type 2 trigeminal neuralgia (TN2) as for those with type 1 trigeminal neuralgia (TN1). The objective of this study is to compare the outcomes of patients with TN1 and TN2 after SRS. ⋯ SRS offers similar rates of initial pain relief, pain score distribution, pain recurrence, and time to pain recurrence between patients with TN1 and TN2. The time to initial pain relief was longer for patients with TN2.

Comparative Study
Comparison of different sequences of MRI and Ultrasongram with Nerve Conduction Studies in peripheral neuropathies.
Peripheral neuropathies refer to a group of disorders in which there is damage to the nerves of the peripheral nervous system. Electrophysiologic studies are the main stay for the diagnosis of peripheral neuropathies. However, direct visualization of the nerves is possible with exact localization of site of disease with high-resolution ultrasonography (USG) and 3-Tesla magnetic resonance imaging (MRI) scanner, and newer magnetic resonance (MR) sequences. ⋯ USG is a sensitive technique to diagnose peripheral neuropathies and it should be used as a screening modality for focused MR to be performed later. Turbo spin echo T2W fast spin has the highest sensitivity to identify nerve disease and is comparable with nerve conduction studies. Among the newer sequences, diffusion tensor imaging should be performed to increase diagnostic confidence.

Large-scale studies analyzing neurosurgical published research are lacking. This pilot study was designed to assess feasibility of an ongoing annual neurosurgical literature and research analysis of published articles in English-language neurosurgery journals. ⋯ This pilot analysis provides a descriptive assessment of levels of evidence and collaboration based on journal, general subject matter, and subcategories of subject allowing for comparison. This methodology may be used on an annual basis to establish neurosurgery publication trends and to identify underrepresented areas of research within the specialty.

We report a case of hemorrhagic tumor detected early by pseudocontinuous arterial spin labeling sequence when conventional magnetic resonance imaging sequences were not contributive.

This prospective study was undertaken to investigate the value of early S100 calcium binding protein B (S100B) and neuron-specific enolase (NSE) in prognosticating outcome in patients with poor-grade aneurysmal subarachnoid hemorrhage and to develop a statistical model and cutoff values for clinical practice. ⋯ S100B and NSE measured during the first 3 days after hemorrhage showed, separately and combined, a significant predictive value in prognosticating clinical outcome in patients with poor-grade subarachnoid hemorrhage. A multicenter study with a large patient cohort is necessary to validate the above-mentioned cutoff values for clinical practice.
