We created a neck trauma model by injecting blood into the sheath of rabbits' carotid bodies (CBs). Then we determined the relationship between neuronal degeneration of the CB due to hemorrhage of this organ and its clinical effects such as blood pH and heart rhythm. ⋯ A high degenerate neuron density in the CB can decrease blood pH and hearth rhythm after neck trauma, and there might be a close relationship between the number of degenerated neurons and clinical findings (such as heart rhythm and blood pH). This relationship suggests that injury to the glossopharyngeal nerve-CB network can cause acidosis by disturbing the breathing-circulating reflex and results in respiratory acidosis.

Endovascular coiling is generally considered as an effective treatment option for ruptured intracranial aneurysms. Increasing operator experience and quality of tools determined an improvement of endovascular cerebral aneurysms' treatment. However, procedure-related complications still occur. The purpose of this study is to report a series of rescue stenting procedures with the Neuroform Atlas (NA) open-cell stent, for intraprocedural complications during coil embolization in patients with ruptured intracranial aneurysms. ⋯ The open-cell NA stent represents a rescue option for coil protrusion during endovascular treatment of ruptured intracranial aneurysms allowing regular restoration of blood flow and minimizing thromboembolic events.

Stereoscopic video recordings of operative microscopy during neuroanatomic dissections are an important component of surgical training and research in well-financed medical schools and teaching hospitals. However, the high cost of the latest operative microscopes with integrated video recording equipment can be a limiting factor in their worldwide use. The aim of the present work is to provide a simple low-cost 3-dimensional (3D) stereoscopic operative microscope recording system that can be used even in economically and resource-limited locations. This is achieved by using readily available smartphones, smartphone accessories, and computer software. ⋯ The 3D video system demonstrated herein can be implemented on any type of operative microscope, including older units for which commercial stereo recording systems are not available. The system and method presented herein can be readily and affordably implemented in low-budget environments for clinical training and research.

Cranioplasty is a relatively simple and straightforward intervention; however, it is associated with a high incidence of postoperative seizures. Postcranioplasty seizures, especially early seizures, are common and associated with poor outcomes and longer hospital stays. Protocols for preventing and managing early seizures have not been well established. ⋯ Cranioplasty is associated with a high incidence of postoperative seizures. Our management protocol for postcranioplasty seizures includes seizure prophylaxis and advanced use of AEDs, which can reduce the occurrence of early seizures.

To compare bony spur resection (BR) with bony spur nonresection (BN) treatment in patients with congenital scoliosis and type I split cord malformation. ⋯ In patients with congenital scoliosis and type I split cord malformation, not resecting the bony spur can achieve satisfactory radiographic and clinical outcomes with potentially fewer complications.
