Orthotic intervention options to non-surgically manage adult and pediatric trigger finger: A systematic review

Leong L, Chai SC, Howell JW, Hirth MJ

J Hand Ther, 2023;36(2):302-315.

PMID: 37391318 DOI: 10.1016/j.jht.2023.05.016

BACKGROUND: The design and efficacy of orthotic intervention to non-surgically manage adult and pediatric trigger finger vary widely.

PURPOSE: To identify types of orthoses (including relative motion), effectiveness, and outcome measurements used to non-surgically manage adult and pediatric trigger finger.

STUDY DESIGN: Systematic review.

METHODS: The study was undertaken according to The Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 Statement and registered with the International Prospective Register of Systematic Reviews Registry, number CRD42022322515. Two independent authors electronically and manually searched, and screened 4 databases; selected articles following pre-set eligibility criteria; assessed the quality of the evidence using the Structured Effectiveness for Quality Evaluation of Study; and extracted the data.

RESULTS: Of the 11 articles included, 2 involved pediatric trigger finger and 9 adult trigger finger. Orthoses for pediatric trigger finger positioned finger(s), hand, and/or wrist of children in neutral extension. In adults, a single joint was immobilized by the orthosis, blocking either the metacarpophalangeal joint or the proximal or distal interphalangeal joint. All studies reported positive results with statistically significant improvements and medium to large effect size to almost every outcome measure, including the Number of Triggering Events in Ten Active Fist 1.37, Frequency of Triggering from 2.07 to 2.54, Quick Disabilities of the Arm, Shoulder and Hand Outcome Measure from 0.46 to 1.88, Visual Analogue Pain Scale from 0.92 to 2.00, and Numeric Rating Pain Scale from 0.49 to 1.31. Severity tools and patient-rated outcome measures were used with the validity and reliability of some unknown.

CONCLUSIONS: Orthoses are effective for non-surgical management of pediatric and adult trigger finger using various orthotic options. Although used in practice, evidence for the use of relative motion orthosis is absent. High-quality studies based on sound research questions and design using reliable and valid outcome measures are needed.

Real time mass flow rate measurement using multiple fan beam optical tomography

This paper presents the implementing multiple fan beam projection technique using optical fibre sensors for a tomography system. From the dynamic experiment of solid/gas flow using plastic beads in a gravity flow rig, the designed optical fibre sensors are reliable in measuring the mass flow rate below 40% of flow. Another important matter that has been discussed is the image processing rate or IPR. Generally, the applied image reconstruction algorithms, the construction of the sensor and also the designed software are considered to be reliable and suitable to perform real-time image reconstruction and mass flow rate measurements.

Effects of different light source and media on growth and production of phycobiliprotein from freshwater cyanobacteria

Khatoon H, Kok Leong L, Abdu Rahman N, Mian S, Begum H, Banerjee S, et al.

Bioresour Technol, 2018 Feb;249:652-658.

PMID: 29091850 DOI: 10.1016/j.biortech.2017.10.052

The aim of this study was to determine the effect of different light sources and media (wastewater and BBM) on the growth of Pseudanabaena mucicola and its phycobiliprotein production. Results showed that P. mucicola grown in white light using wastewater as medium attributed higher biomass (0.55 g L-1) and when extracted with water, also showed significantly higher (P 

Fulltext 2017 Multimodality Appropriate Use Criteria for Noninvasive Cardiac Imaging: Expert Consensus of the Asian Society of Cardiovascular Imaging

ASCI Practice Guideline Working Group, Beck KS, Kim JA, Choe YH, Sim KH, Hoe J, et al.

Korean J Radiol, 2017 Nov-Dec;18(6):871-880.

In 2010, the Asian Society of Cardiovascular Imaging (ASCI) provided recommendations for cardiac CT and MRI, and this document reflects an update of the 2010 ASCI appropriate use criteria (AUC). In 2016, the ASCI formed a new working group for revision of AUC for noninvasive cardiac imaging. A major change that we made in this document is the rating of various noninvasive tests (exercise electrocardiogram, echocardiography, positron emission tomography, single-photon emission computed tomography, radionuclide imaging, cardiac magnetic resonance, and cardiac computed tomography/angiography), compared side by side for their applications in various clinical scenarios. Ninety-five clinical scenarios were developed from eight selected pre-existing guidelines and classified into four sections as follows: 1) detection of coronary artery disease, symptomatic or asymptomatic; 2) cardiac evaluation in various clinical scenarios; 3) use of imaging modality according to prior testing; and 4) evaluation of cardiac structure and function. The clinical scenarios were scored by a separate rating committee on a scale of 1-9 to designate appropriate use, uncertain use, or inappropriate use according to a modified Delphi method. Overall, the AUC ratings for CT were higher than those of previous guidelines. These new AUC provide guidance for clinicians choosing among available testing modalities for various cardiac diseases and are also unique, given that most previous AUC for noninvasive imaging include only one imaging technique. As cardiac imaging is multimodal in nature, we believe that these AUC will be more useful for clinical decision making.
