Mechanical thrombectomy with the Trevo ProVue device in ischemic stroke patients: does improved visibility translate into a clinical benefit?

Purpose: To investigate the efficacy and safety of the Trevo ProVue (TPV) stent retriever in stroke patients with large artery occlusions, with particular attention to the full structural radiopacity of the TPV.

Materials And Methods: Case files and images of TPV treatments were reviewed for clinical and technical outcome data, including revascularization rates, device and procedure related complications, and outcome at discharge and after 90 days.

Results: 76 patients were treated with TPV.

Implantation of venous access devices under local anesthesia: patients' satisfaction with oral lorazepam.

Objective: The aim of the study reported here was to evaluate patients' satisfaction with implantation of venous access devices under local anesthesia (LA) with and without additional oral sedation.

Materials And Methods: A total of 77 patients were enrolled in the prospective descriptive study over a period of 6 months. Subcutaneous implantable venous access devices through the subclavian vein were routinely implanted under LA.

Intraoperative functional magnetic resonance imaging for monitoring the effect of deep brain stimulation in patients with obsessive-compulsive disorder.

Objectives: To investigate the effects of low- and high-frequency deep brain stimulation (DBS) on the nucleus accumbens (ACC) and the adjacent internal capsule in 3 patients with obsessive-compulsive disorder (OCD) using blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) under intraoperative conditions.

Methods: After placement of the electrode in the right ACC, the patients underwent an MR scan inside the operating room. BOLD imaging was performed and interpreted using a boxcar paradigm with alternating high-frequency stimulation of the ACC and the internal capsule versus rest.

Epithelial marker expression in Salzmann nodular degeneration shows characteristics of limbal transient amplifying cells and alludes to an involvement of the epithelium in its pathogenesis.

Purpose: To look at the epithelial nature of Salzmann nodular degeneration (SND) and its possible relation with the aetiology of the subepithelial collagen deposition.

Methods: Histological slides of 28 patients with SND were analysed for limbal and central corneal epithelial markers. Expression pattern of these markers in the basal layer of the epithelium was analysed and compared to the expression pattern in central corneal and limbal epithelium.
