Accuracy of frameless robot-assisted stereoelectroencephalography depth electrode implantation using the neurolocate registration system in paediatric patients.

Background: We assessed the accuracy and performed a directional analysis of robot-assisted implantation of stereoelectroencephalography (SEEG) depth electrodes in children using the frameless neurolocate 3D registration module.

Methods: Thirteen children with epilepsy undergoing stereotactic robot-assisted insertion of SEEG electrodes were included. Six children were operated on with standard frame-based registration while 7 with the use of the frameless neurolocate registration module.

Impact of intraoperative MRI on pediatric epilepsy surgery for focal cortical dysplasia.

Background: Complete resection is essential for achieving seizure freedom in children with drug-resistant epilepsy due to focal cortical dysplasia (FCD). However, identifying altered structures intraoperatively can be challenging, potentially leading to reoperations. This study assessed the impact of intraoperative MRI (iMRI).

A Case of Bilateral Carotid Body Tumors Requiring Surgical Resection: The Importance of Physical Exams.

We present the case of a 61-year-old man who presented to his primary care provider for a routine visit and was found to have a pulsatile mass in his right neck. This case report shows the importance of a thorough physical exam during patient visits. In this case, the physical exam resulted in the diagnosis of a carotid body tumor (CBT) prior to the patient becoming symptomatic from it.

Synthesis, mixed-spin-state structure and Langmuir-Blodgett deposition of amphiphilic Fe(iii) quinolylsalicylaldiminate complexes.

Designing and integrating Fe(iii)-based spin crossover (SCO) complexes onto substrates remains a challenging goal with only a handful of examples reported. In this work, we successfully synthesized and characterized three [Fe(qsal-OR)]NO (qsal-OR = 5-alkoxy-2-[(8-quinolylimino)methyl]phenolate) complexes, in which R = CH1, CH2, and CH3 to explore the impact of alkyl chain on the modulation of SCO activity and potential for self-assembly on a glass surface. The SCO is found to be gradual and incomplete in all cases, with the LS state more stabilised as the alkyl group shortens.

Subclavian-Carotid Bypass as a Solution to Recurrent Carotid Artery Stenosis Post Endarterectomy and Transfemoral Stenting.

We present the case of an 80-year-old man who underwent a subclavian-to-distal internal carotid artery bypass with a reversed saphenous vein due to symptomatic in-stent restenosis, following a carotid endarterectomy 20 years ago and carotid artery stenting 10 years ago. The patient presented with right-sided hemiparesis and dysarthria. Imaging suggested in-stent restenosis of the internal carotid artery stent.
