This deep-dive into acromioclavicular joint injuries unpacks everything a physician needs to know about these prevalent injuries. Acromioclavicular joint (ACJ) injuries, mostly traumatic, can occur across all ages but are more frequent in males aged 20-40, often related to contact sports. Patients usually present with vague shoulder pain and swelling, but visible deformity is rare. Two mechanisms contribute to ACJ injuries: direct, resulting from a direct blow or fall onto the shoulder, and indirect, arising from a fall onto an outstretched hand or elbow. Imaging is crucial for diagnosis. The Rockwood system, among others, categorizes these injuries into six types. Plain radiographs, including an axillary view, generally suffice for accurate grading. However, in certain scenarios, CT or MRI might be necessary. In case of an injury suspicion with initial normal radiographs or contemplating surgical intervention on a type III injury, additional weight-bearing stress views can be beneficial. Indications of ACJ injury on a plain radiograph may include soft tissue swelling, acromioclavicular joint widening, increased coracoclavicular distance, and superior displacement of the distal clavicle. The treatment choice hinges largely on the patient’s age, lifestyle, and injury type. Conservative management typically applies to types I and II injuries, surgical treatment to types […]

This 1-Minute Consult reviews the bedside workup of delirium and possible stroke and reviews the cases for – and against – imaging.

Despite the fact that OCT angiography (OCTA) does not technically qualify as multimodal imaging per se, it does offer several modes of visualization from a single scan, including an angiogram, a structural picture, and en face imaging with boundary specific segmentation. The use of OCTA can assist doctors in communicating to patients with geographic atrophy who are susceptible to exudation the necessity for routine follow-up. Clinicians can rule out artifacts by analyzing the flow overlay on the OCTA cross-section. If the flow isn’t where it should be for the illness, it’s probably an artifact.

Per Svenningsson, MD, PhD, a neurologist with expertise in Parkinson’s disease, will serve as the multicenter trial’s principal investigator. He previously oversaw a clinical study using montelukast (Singulair) tablets to treat PD. The multicenter trial is anticipated to begin between July and September. During the 18-month trial, participants will be randomized to receive either montelukast VersaFilm or a placebo film. IntelGenx plans to use the results to enhance the clinical development of its montelukast VersaFilm for Parkinson’s.

A prospective cohort study of 629 patients with non-MRI-conditional ICDs from 2003 to 2013, including 813 MRIs, concludes that the devices continue to function properly after MRI.

The assessment of response to radiation-based therapies can be complicated by persistent or changing imaging features, and this field of study is still in active development even though imaging-based response assessment systems have been validated for the evaluation of response to ablative locoregional therapies. Research is still needed to address the shortcomings of current imaging criteria for evaluating tumor response to these novel techniques, despite the increased application of radiation-based local-regional therapies for the treatment of HCC following technological advancements and a better understanding of tumor biology.
