#1
Eric Quan Pang, Nathan Douglass, Robin N Kamal
BACKGROUND: We examined the relationship between lunate morphology (type 1 without a medial facet; type II with a medial facet) and dorsal intercalated segmental instability (DISI) in patients with scapholunate ligament injuries. We tested the primary null hypothesis that there is no relationship between lunate morphology and development of DISI. Secondary analysis compared the agreement of classifying lunate morphology based on the presence of a medial lunate facet, capitate-to-triquetrum (CT) distance, and magnetic resonance imaging (MRI)...

D Macía-Suárez, E Sánchez-Rodríguez, B Lopez-Calviño, C Diego, M Pombar
AIM: To assess whether low voltage chest computed tomography (CT) can be used to successfully diagnose disease in patients with asbestos exposure. MATERIALS AND METHODS: Fifty-six former employees of the shipbuilding industry, who were candidates to receive a standard-dose chest CT due to their occupational exposure to asbestos, underwent a routine CT. Immediately after this initial CT, they underwent a second acquisition using low-dose chest CT parameters, based on a low potential (80 kV) and limited tube current...

Current orthopaedic clinical methods do not provide an objective measure of fracture healing or weight bearing for lower extremity fractures. The following report describes a novel approach involving in-situ strain sensors to objectively measure fracture healing. The sensor uses a cantilevered indicator pin that responds to plate bending and an internal scale to demonstrate changes in the pin position on plain film radiographs. The long lever arm amplifies pin movement compared to interfragmentary motion, and the scale enables more accurate measurement of position changes...

A myopericytoma (MP) is an exceedingly rare perivascular tumor of unknown etiology. Given their potential for mimicry and malignancy, MP tumors pose a unique challenge for surgeons and may be overlooked on differential diagnosis. We present a case report of an otherwise healthy 33-year-old right-hand dominant male who presented to our outpatient clinic with a 2-month history of painless swelling and erythema of the pulp of his left index finger. Subsequent plain film X-ray showed near-complete bony destruction of his distal phalanx...

The lipopeptide surfactin produced by certain strains of Bacillus subtilis is a powerful biosurfactant possessing potentially useful antimicrobial properties. In order to better understand its surface behavior, we have used surface sensitive sum frequency generation (SFG) vibrational spectroscopy in the C-H and C═O stretching regions to determine its structure at the air/water interface. Using surfactin with the leucine groups of the peptide ring perdeuterated, we have shown that a majority of the SFG signals arise from the 4 leucine residues...

INTRODUCTION: Emergency department (ED) crowding is widespread, and can result in care delays, medical errors, increased costs, and decreased patient satisfaction. Simultaneously, while capacity constraints on EDs are worsening, contributing factors such as patient volume and inpatient bed capacity are often outside the influence of ED administrators. Therefore, systems engineering approaches that improve throughput and reduce waste may hold the most readily available gains. Decreasing radiology turnaround times improves ED patient throughput and decreases patient waiting time...

Patients rarely present to a chiropractic office setting during the acute stage of a high-grade (i.e. Rockwood types IV-VI) separation of the acromioclavicular (AC) joint. Moreover, such cases are non-existent in the peer-reviewed chiropractic literature. Some controversy exists over the optimal (surgical vs. non-surgical) treatment of severe AC joint injuries. Published reports of nonoperative management for grade V injuries of the AC joint are also scarce. This case review highlights the plain film imaging and conservative management of a 57-year-old patient diagnosed with an acute Rockwood type V AC joint separation...

The knee joint is involved in a wide variety of arthritides, and imaging has always played a major role in both aiding diagnosis and assessing the severity of such diseases. Plain film radiography has traditionally been used as the primary imaging modality for radiographic diagnosis of arthritis. However, magnetic resonance imaging (MRI) shows a greater sensitivity to both the bone and soft tissue features of this group of conditions. This article reviews the imaging features of osteoarthritis (OA) of the knee shown on MRI and the criteria used to diagnose this condition...
