Stress radiography of the knee offers a relatively objective and Diagnostics 2021, 11, 419. https://doi.org/10.3390/diagnostics11030419 https://www.mdpi.com/journal/diagnostics Diagnostics 2021, 11, 419 2 of 11 measurable approach to quantify the anterior tibial translation when applying force to the knee [4–7]. A prior study has focused on the effect of knee position on the reproducibility of measurements taken from stress radiography [8]. A different knee flexion angle, injury extent, muscle guarding, and femoral rotation affect the laxity measurement using stress radiography [4,9,10]. Another study compared different measuring methods and assessed the intra-class correlation coefficient of each method to evaluate the knee instability [11]. However, the reliability of manual measurements done by different readers and different methods is questionable. Several automatic methods for objective measurement of joint space or angle using computer-assisted systems have recently been developed [12–14]. Automatic computer image assessment and analysis system can segment the femur, tibia, and patella using an edge-based method. Then, some landmarks to calculate tibial translation distance can be defined using a segmentation algorithm. In this study, we designed a computer-assisted system that automatically segmented bone contours of the knee and, subsequently, measured the distance of anterior tibial trans- lation in stress radiography. The diagnostic performances of different methods for ACL injury were evaluated. It was hypothesized that we could use our computer-assisted sys- tem to (1) evaluate the diagnostic performance of stress radiography for ACL insufficiency by different measurement methods, and (2) assess the effects of age, gender, time interval between stress radiography and MRI, and technical factors on the diagnostic accuracy. 2. Materials and Methods 2.1. Patients Institutional Review Board approval was obtained, and the requirement to obtain informed consent was waived. A retrospective search of the Picture Archiving and Com- munication System (PACS) for patients with both knee stress radiography by Telos device (Metax, Hungen, Germany) and MRI at our institution was performed. The MRI was reviewed by one musculoskeletal radiologist, and the status of ACL was classified into complete tear, partial tear, or no tear. If the review did not match the previous report, a musculoskeletal radiologist with more than 20 years of experience made the final decision. The patients were divided into one group with a complete ACL tear, and another group without a complete ACL tear. The time interval between stress radiography and MRI was recorded. A total of 399 patients with stress radiography and MRI for evaluation of ACL injury were included in this study, from which 150 patients were excluded (Figure1). In addition, 28 patients were diagnosed as multiple ligamentous injuries on MRI, while 15 patients with the torn meniscus had displaced fragments. Nine patients were excluded due to long interval (>9 weeks) between stress radiography and MRI. Furthermore, 27 patients were excluded due to anatomic shape changes by severe osteoarthritis, fractures, or intraar- ticular loose bodies, 36 patients were excluded due to a previous knee surgery, 18 patients were excluded because of unsatisfactory device position to obscure the segmentation, and another 17 patients were excluded due to poor image quality. Imaging data processing and a tibial translation measurement were performed in the remaining 249 patients.

Taipei 10608, Taiwan 2Department of Occupational Therapy, I-Shou University, No. 8, Yida Rd., Jiaosu Village, Yanchao District, Kaohsiung 82445, Taiwan (Received March 28, 2018; accepted October 18, 2018) Keywords: rehabilitation system, depth sensors, action identification techniques, schizophrenia, physical fitness Nowadays, there are many human pose estimation systems that extract skeletons or skeleton points from depth sensors. These action identification systems have been developed for somatosensory games for entertainment use, and some of these have been used for medical purposes. Most of these have proven that the action identification technology is practical, but its medical use has not been confirmed. Therefore, besides the general treatment of mental illness, we tried to add a rehabilitation program to promote physical fitness based on a vision- based action sensor system. It is expected to effectively improve the physical functions of patients with mental illness. There are some somatosensory games that claim that they can achieve the effects of sports and entertainment, and some of these have been used for the physical training and physical rehabilitation, but none of them have been used for the physical rehabilitation of patients with schizophrenia. Thus, the purpose of this study was to examine the effects of a rehabilitation system with efficient vision-based action identification techniques on physical fitness promotion in patients with schizophrenia through the sequential-withdrawal design of a single subject research.

Published by Lippincott Williams & Wilkins Adjunctive Hyperbaric Oxygen Therapy for Healing of Chronic Diabetic Foot Ulcers A Randomized Controlled Trial Chen-Yu Chen ¡ Re-Wen Wu ¡ Mei-Chi Hsu ¡ Ching-Jung Hsieh ¡ Man-Chun Chou ABSTRACT PURPOSE: The purpose of this study was to compare the effect of standard wound care with adjunctive hyperbaric oxygen therapy (HBOT) to standard wound care alone on wound healing, markers of infl ammation, glycemic control, amputation rate, survival rate of tissue, and health-related quality of life in patients with diabetic foot ulcers (DFUs). DESIGN: Prospective, randomized, open-label, controlled study. SUBJECTS AND SETTING: The sample comprised 38 patients with nonhealing DFUs who were deemed poor candidates for vascular surgery. Subjects were randomly allocated to an experimental group (standard care plus HBOT, n = 20) or a control group (standard care alone, n = 18). The study setting was a medical center in Kaohsiung City, Taiwan. METHODS: Hyperbaric oxygen therapy was administered in a hyperbaric chamber under 2.5 absolute atmospheric pressure for 120 minutes; subjects were treated 5 days a week for 4 consecutive weeks. Both groups received standard wound care including debridement of necrotic tissue, topical therapy for Wagner grade 2 DFUs, dietary control and pharmacotherapy to maintain optimal blood glucose levels. Wound physiological indices were measured and blood tests (eg, markers of infl ammation) were undertaken. Health-related quality of life was measured using the Medical Outcomes Study 36-Item Short Form. RESULTS: Complete DFU closure was achieved in 5 patients (25%) in the HBOT group (n = 20) versus 1 participant (5.5%) in the routine care group (n = 18) ( P = .001).

  • Magnetic Resonance Imaging Is Useful for Diagnosis of Sacral Insufficiency Fracture and Target Identification in Sacroplasty
    Brief Communication Magnetic Resonance Imaging is Useful for Diagnosis of Sacral Insufficiency Fracture and Target Identification in Sacroplasty Feng-Chen Kao1,2, Yao-Chun Hsu3-6, Pao-Hsin Liu7, Yuan-Kun Tu1,2 Sacral insufficiency fractures (SIFs) are typically missed in roentgenograms and often neglected by clinical physicians. Magnetic resonance imaging (MRI) can detect early changes in SIF as bone marrow edema (low signal intensity at T1-weighted images and high signal intensity at T2- weighted images) at the sacral area (both the sacral body and sacral alar area). The patterns of SIF include unilateral or bilateral involvement in the sacral ala, with or without the sacral body involved, or transverse fractures of the lower sacrum. The approaches of sacroplasty include the following: the transiliac approach, the long-axis approach and the short-axis approach. The target could be identified on the area of SIF according to MRI findings.

However, TACE in combination with radiofrequency ablation (RFA) is not inferior to surgical resection (SR), and the benefits of surgical resection (SR) for BCLC stage B HCC remain unclear. Hence, this study aims to compare the impact of SR, TACE+RFA, and TACE on analyzing overall survival (OS) in BCLC stage B HCC. Methods: Overall, 428 HCC patients were included in BCLC stage B, and their clinical data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Results: One hundred forty (32.7%) patients received SR, 57 (13.3%) received TACE+RFA, and 231 (53.9%) received TACE. The OS was significantly higher in the SR group than that in the TACE+RFA group [hazard ratio (HR): 1.78; 95% confidence incidence (CI): 1.15–2.75, p = 0.009].
