Mohs Micrographic Surgery With Digital Pathology Improves Surgical Quality and Efficiency: A Retrospective Cohort Study.

Background: Mohs micrographic surgery, involving pathology of the surgical margin, has the lowest recurrence rate for skin cancer. Moreover, because of technological advances, digital pathology systems are gradually being adopted in hospitals. Yongin Severance Hospital was the first hospital to construct a fully digitalized pathology system in Korea.

Outcomes of bone marrow aspirate concentrate and matrix-induced chondrogenesis (BMIC) for treatment of osteochondral lesions of the talus.

Background: To analyze the outcomes of Bone marrow aspirate concentrate and Matrix-Induced Chondrogenesis (BMIC) in Osteochondral Lesions of the Talus (OLTs).

Methods: Patients with OLTs treated with BMIC from June 2013 to July 2020 were included. Visual Analogue Scale (VAS), Foot Function Index (FFI), and Foot Ankle Outcome Score (FAOS) before treatment and at last follow-up were subjected to analysis.

Glioblastoma Cellular Origin and the Firework Pattern of Cancer Genesis from the Subventricular Zone.

Glioblastoma (GBM) is a disease without any definite cure. Numerous approaches have been tested in efforts to conquer this brain disease, but patients invariably experience recurrence or develop resistance to treatment. New surgical tools, carefully chosen samples, and experimental methods are enabling discoveries at single-cell resolution.

Baha Attract Implantation Using a Small Incision: Initial Report of Surgical Technique and Surveillance.

Objectives: To determine the appropriate anatomical borders of implantation on the temporal bone in a cadaver study, and to develop a simplified surgical technique for Baha Attract implantation through a small incision along the hairline using anatomical evidence and a navigation system.

Methods: In a cadaver study, 20 human adult dry skulls were used to find flat areas of the temporal bone for Baha Attract magnet implantation. Four borders of the "optimal surgical site" were defined: Asterion line, occipitomastoid suture line, sigmoid sinus line, and digastric groove line.

Cleaved Cochlin Sequesters Pseudomonas aeruginosa and Activates Innate Immunity in the Inner Ear.

In the inner ear, endolymph fluid surrounds the organ of Corti, which is important for auditory function; notably, even slight environmental changes mediated by trauma or infection can have significant consequences. However, it is unclear how the immune response is modulated in these tissues. Here, we report the local immune surveillance role of cleaved cochlin LCCL (Limulus factor C, Cochlin, and Lgl1) during Pseudomonas aeruginosa infection in the cochlea.

Use of dynamic images in radiology education: Movies of CT and MRI in the anatomy classroom.

Radiology education is a key component in many preclinical anatomy courses. However, the reported effectiveness of radiology education within such anatomy classrooms has varied. This study was conducted to determine if a novel educational method using dynamic images of movies of computed tomography (CT) and magnetic resonance imaging (MRI) was effective in radiology education during a preclinical anatomy course, aided by clay modeling, specific hand gestures (digit anatomy), and reports from dissection findings uploaded to the anatomy course website (digital reports).

Mapping of lateral pelvic lymph node recurrences in rectal cancer: a radiation oncologist's perspective.

Purpose: Patterns of locoregional rectal cancer recurrences following total mesorectal excision (TME) were analyzed to define the irradiation volume, especially the lateral pelvic lymph node (LPLN).

Materials And Methods: Of 1243 patients who underwent TME without pelvic radiotherapy between 2005 and 2012, the data of 826 patients with rectal adenocarcinoma without distant metastases were analyzed for relapse patterns, categorized as distant and locoregional (anastomosis, mesorectum, presacral area, and LPLNs) failure.

Results: The median follow-up was 61.

Safety and feasibility of reduced-port robotic distal gastrectomy for gastric cancer: a phase I/II clinical trial.

Introduction: Theoretically, reducing the number of ports required in minimally invasive surgery for gastric cancer would further minimize trauma associated therewith. Advances in single-site surgery have afforded surgeons the ability to perform reduced-port distal gastrectomy via a robotic approach using the Single-Site™ system, eliminating restrictions on the movement of surgical instruments.

Methods: This phase I/II study was designed as a single-arm prospective trial of reduced-port robotic distal gastrectomy (RRDG) by a single surgeon (NCT02347956).

Robotic extrahepatic Glissonean pedicle approach for anatomic liver resection in the right liver: techniques and perioperative outcomes.

Background: The Glissonean pedicle approach is one of the most popular methods of anatomic liver surgery. Liver surgeons have attempted to reproduce this method laparoscopically. In this study, we introduce our technique of the extrahepatic Glissonean approach for anatomic liver resections, using a robotic system, and report on short-term perioperative outcomes.

Scleral fixation of standard capsular tension ring and in-the-bag intraocular lens implantation in patients with severe lens subluxation.

The authors introduce a new technique for scleral fixation using a standard capsular tension ring for in-the-bag use in patients with a lens dislocated by more than 180°. Three patients with zonulysis and phacodonesis underwent surgery with this technique, and all of the patients showed stable maintenance in visual acuity after an average of 22.7 months (range: 14 to 30 months) of follow-up.

"Digit anatomy": a new technique for learning anatomy using motor memory.

Gestural motions of the hands and fingers are powerful tools for expressing meanings and concepts, and the nervous system has the capacity to retain multiple long-term motor memories, especially including movements of the hands. We developed many sets of successive movements of both hands, referred to as "digit anatomy," and made students practice the movements which express (1) the aortic arch, subclavian, and thoracoacromial arteries and their branches, (2) the celiac trunk, superior mesenteric artery and their branches, and formation of the portal vein, (3) the heart and the coronary arteries, and (4) the brachial, lumbar, and sacral plexuses. A feedback survey showed that digit anatomy was helpful for the students not only in memorizing anatomical structures but also in understanding their functions.
