Background And Objective: To evaluate the optical coherence tomography angiography (OCTA) features of patients with Behçet disease (BD) without ocular involvement.
Patients And Methods: Twenty-three patients with BD without ocular involvement and 29 healthy age/sex-matched control subjects were involved. The authors measured foveal avascular zone (FAZ) area, vessel density in the parafoveal region, and flow area (fovea-centered 3-mm radius area) in the superficial and deep capillary plexuses evaluated by OCTA.
Results: FAZ area was significantly larger in eyes with BD in both the superficial and deep capillary plexuses (0.331 vs. 0.240 mm [P = .004] and 0.352 vs. 0.257 mm [P = .003], respectively). Although mean capillary vessel density in parafoveal region and mean flow area were lower in eyes with BD for both superficial and deep capillary plexuses, these findings were not statistically significant.
Conclusion: Microvascular changes in macular region can be identified in patients with BD without ocular manifestation. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:31-34.].

Background: Standardized surgical approaches to advanced pre-auricular cutaneous squamous cell carcinomas (cSCC) are lacking.
Methods: Fifty-four patients who underwent lateral temporal bone resection (LTBR) for pre-auricular cSCC were grouped into "Levels" of increasing disease spread. Surgical approaches to achieve negative-margin resection were designed for each Level and replicated on cadaveric specimens.

Department of Orthopaedic Surgery and Rehabilitation, University of Florida-Jacksonville, Jacksonville, FL USA. Electronic address:
Introduction: External fixators are utilized to temporarily stabilize bicondylar tibial plateau fractures. They can be prepped during definitive surgery to help maintain fracture length and alignment. However, there is a potential for increased infection by leaving the external fixator on during the surgery.

January 2025
Backgrounds/objective: Deep brain stimulation (DBS) has proved the viability of alleviating depression symptoms by stimulating deep reward-related nuclei. This study aims to investigate the abnormal connectivity profiles among superficial, intermediate, and deep brain regions within the reward circuit in major depressive disorder (MDD) and therefore provides references for identifying potential superficial cortical targets for non-invasive neuromodulation.
Methods: Resting-state functional magnetic resonance imaging data were collected from a cohort of depression patients (N = 52) and demographically matched healthy controls (N = 60).
