Abstract Background Hand tendon injuries are recognized clinical entities that are frequently seen. Clinical examinations usually warrant radiological correlative studies for confirmation and as a postoperative screening test. Here is a prospective observational cohort study enrolling 30 patients who were diagnosed clinically to have hand tendon injuries either pre- or postoperative; their ages were ranging from 5 to 64 years with a mean ± SD of 31.43 ± 12.19 years; 23 male patients (76.7%) and 7 female patients (23.3%) were evaluated by high-resolution ultrasound examination and a correlative evaluation was done by either intra-operative assessment or MRI study as gold standards. Results High-resolution ultrasound (HRUS) findings were binned into seventeen cases (56%) that had tendon tears, of which 10 cases (33.3%) had a complete tear and 7 cases (23.3%) had a partial tear. Postoperative tendon integrity was present in 13 cases (43.3%), a tendon callus was found in 2 cases (6.66%), and a postoperative abnormal motion on the dynamic study was present in 15 cases (50%). Intra-tendinous foreign bodies were detected in two cases (6.66%), a gap between the torn ends was found in 10 cases (33.3%), and re-tear (rupture) of the repaired tendons was present in four cases (13.3%). Coexistent nerve injuries were seen in two cases (6.66%); for the forementioned findings, HRUS had gained high accuracy measures as correlated to the gold standards (100% sensitivity and 100% specificity). Conclusion High-resolution ultrasound serves as a highly accurate potential diagnostic modality for preoperative evaluation of hand tendon injuries and the postoperative follow-up.

Identification of the primary source of pain determines the success of musculoskeletal pain management. A detailed history and physical examination are the current gold standards for identifying musculoskeletal pain source in day-to-day clinical practice. This process, at times, may potentially result in inadequate/inappropriate identification of the pain source. In this case report, we present the usefulness of a simple and inexpensive vacuum cup. We found that this accurately identified the primary pain source, distant from and unrelated to the site of pain presentation in a 30-year-old man with back pain. Routine use of this simple technique in conjunction with the regular musculoskeletal examination may better identify primary restrictions in the body tissues. Based on our experience, we propose that this approach has the potential to offer better outcomes in the treatment of musculoskeletal pain in the future.

Can the spherical gold standards be used as an alternative to painted gold standards for the computerized detection of lesions using voxel-based classification?

Engineering design idea-generation sessions often result in dozens, if not hundreds, of ideas. These ideas must be quickly evaluated and filtered in order to select a few candidate concepts to move forward in the design process. While creativity is often stressed in the conceptual phases of design, it receives little attention in these later phases — particularly during concept selection. This is largely because there are no methods for quickly rating or identifying worthwhile creative concepts during this process. Therefore, the purpose of this study was to develop and test a novel method for evaluating the creativity and feasibility of design concepts and compare this method to gold standards in our field. The SCAT method employed in this paper uses word selections and semantic similarity to quickly and effectively evaluate candidate concepts for their creativity and feasibility. This method requires little knowledge of the rating process by the evaluator. We tested this method with 10 engineering designers and three different design tasks. Our results revealed that SCAT ratings can be used as a proxy for measuring design concepts but there are modifications that could enhance its utility. This work contributes to our understanding of how to evaluate creativity after idea generation and provides a framework for further research in this field.
