Ultrasonic scalpel-assisted endoscopic endonasal surgery of infratemporal fossa: our first impressions.

World Neurosurg 2018 Dec 3. Epub 2018 Dec 3.

Division of Otorhinolaryngology, Department of Biotechnology and Life Sciences, HNS&FDRc, University of Insubria, Varese, Italy.

Background: Endoscopic endonasal transpterygoid approach is emerging as a valid option for treating selected tumors in the infratemporal fossa. Compared to traditional open approaches, the endoscopic endonasal approach (EEA) presents more difficulty in controlling bleeding and less choice in surgical instruments for endoscopic tumor dissection, which is often performed with bipolar forceps or steel dissectors.

Case Description: We describe the use of an ultrasonic scalpel device for performing endoscopic endonasal resection of two rare infratemporal fossa tumors (mature teratoma and hemangiopericytoma), which has not been reported in the literature so far. Read More

Cracking the Function of Layers in the Sensory Cortex.

Neuron 2018 Dec;100(5):1028-1043

Department of Molecular and Cell Biology, University of California, Berkeley, Berkeley, CA, USA; The Helen Wills Neuroscience Institute, University of California, Berkeley, Berkeley, CA, USA.

Understanding how cortical activity generates sensory perceptions requires a detailed dissection of the function of cortical layers. Despite our relatively extensive knowledge of their anatomy and wiring, we have a limited grasp of what each layer contributes to cortical computation. We need to develop a theory of cortical function that is rooted solidly in each layer's component cell types and fine circuit architecture and produces predictions that can be validated by specific perturbations.

Stent-assisted balloon-induced intimal disruption and relamination of distal remaining aortic dissection after acute DeBakey type I repair.

J Thorac Cardiovasc Surg 2018 Oct 17. Epub 2018 Oct 17.

Department of Cardiac and Vascular Surgery, Hôpital Européen Georges Pompidou, AP-HP, Paris, France; INSERM U970, Faculté de Médecine Paris-Descartes, Université Paris 5, Paris, France.

Objectives: Surgical repair in patients with acute DeBakey type I aortic dissection (ADIAD) achieves good short-term results, but in several patients the false lumen remains patent in the descending aorta because of distal intimal tears with persisting risk for distal aneurismal evolution. We report the short- and mid-term outcomes of the stent-assisted balloon-induced intimal disruption and relamination of aortic dissection (STABILISE) technique for the 16 first patients treated for a residual dissection of the descending thoracic aorta after repaired ADIAD.

Methods: We reviewed all patients treated with STABILISE for a remaining distal thoracoabdominal aortic dissection after ADIAD repair. Read More
