Patients with frontal glioma might experience cognition alterations together with potential dysfunction of resting-state networks (RSNs). To understand the altered patterns of the intrinsic activity and underlying network interactions between the cognitive-related RSNs is of great importance. ⋯ Our results suggested underlying network functional reorganization of the triple unifying RSNs in patients with frontal glioma, providing novel insights for improving understanding of brain function.

Laminar wall sheer stress (LWSS) modulates inflammatory activity of the endothelium and may be a contributing factor in many cerebrovascular pathologies. There is a lack of consensus whether significant differences in LWSS exist between feeding vessels in brain arteriovenous malformation (bAVM) and healthy vessels. A systematic review of LWSS research in bAVM was undertaken, including the methods used and the assumptions made in determining LWSS. ⋯ mLWSS values in healthy arteries and bAVM feeding vessels tend to be low and overlapping. Further research of high scientific and methodologic quality is necessary to improve understanding of how LWSS hemodynamics relate to bAVM formation, rupture, and treatment.

To describe the technical details of 3-piece orbitozygomatic (OZ) craniotomy using a diamond threadwire saw as an alternative to cutting the orbital rim and zygoma. ⋯ The herein-described 3-piece OZ craniotomy technique is simple and provides excellent brain exposure equivalent to that achieved by 1- and 2-piece OZ craniotomy while minimizing flap retraction and requiring less additional bone removal.

Differentiating pyogenic spondylitis (PS) and tuberculous spondylitis (TS) is challenging but critical in clinical practice. Accurate diagnosis and early treatment are crucial to preventing further progression of disease. Magnetic resonance imaging (MRI) is considered the best method for the diagnosis of spinal infection, but results remain imprecise; therefore, by comparing and analyzing the MRI findings of spinal infections, we intend to identify key distinguishing features between PS and TS, and with that establish a systematic scoring method to help clinicians. ⋯ Our systematic scoring system of MRI parameters is helpful in differentiating PS and TS.

The Hoffmann sign is usually used as an indicator of upper motor neuron lesion, but its clinical effect remains controversial in previous reports. ⋯ Although the Hoffmann sign is not foolproof in the diagnosis of cervical spinal cord compression, it can be used to assess symptomatic patients. The narrower the cervical spine canal or the higher the cervical segment compression, the higher of the incidence of positive Hoffmann sign.
