Value of ultrasound-assessed dactylitis in the early diagnosis of psoriatic arthritis.
Semin Arthritis Rheum
December 2024
Department of Rheumatology and Joint and Bone Research Unit. Fundación Jiménez Díaz University Hospital and Health Research Institute Fundación Jiménez Díaz (IIS-FJD, UAM), Autonomous University of Madrid, Madrid, Spain. Electronic address:
Purpose: The primary objective of this prospective, longitudinal, observational, single-centre study was to evaluate the association between ultrasound-assessed lesions of dactylitis and the diagnosis of psoriatic arthritis (PsA) in patients with psoriasis (PsO) and hand arthralgia.
Methods: We included adult patients diagnosed with PsO with hand arthralgia, with or without other musculoskeletal complaints. They were clinically assessed at baseline, 6 and 12 months by a rheumatologist blinded to the ultrasound findings.
Ultra High-Frequency Ultrasound of Median Nerve Fascicles at the Wrist in Amyotrophic Lateral Sclerosis: An Exploratory Study.
J Clin Neurophysiol
December 2024
Department of Neurology, Wake Forest University School of Medicine, Winston-Salem, North Carolina, U.S.A.
Purpose: High-frequency ultrasound (HFUS) of muscle and nerve has the potential to be a reliable, responsive, and informative biomarker of disease progression for individuals with amyotrophic lateral sclerosis (ALS). High-frequency ultrasound is not able to visualize median nerve fascicles to the same extent as ultra-high-frequency ultrasound (UHFUS). Evaluating the number and size of fascicles within a nerve may facilitate a better understanding of nerve diseases.

From the Institute for Diagnostic and Interventional Radiology, University Hospital Zurich, University Zurich, Zurich, Switzerland (B.K., F.E., J.K., T.F., L.J.); Advanced Radiology Center, Department of Diagnostic Imaging and Oncological Radiotherapy, Fondazione Policlinico Universitario "A. Gemelli" IRCCS, Rome, Italy (C.S., A.R.L.); and Section of Radiology, Department of Radiological and Hematological Sciences, Università Cattolica del Sacro Cuore, Rome, Italy (A.R.L.).
Objectives: The aim of this study was to evaluate the feasibility and efficacy of visual scoring, low-attenuation volume (LAV), and deep learning methods for estimating emphysema extent in x-ray dose photon-counting detector computed tomography (PCD-CT), aiming to explore future dose reduction potentials.
Methods: One hundred one prospectively enrolled patients underwent noncontrast low- and chest x-ray dose CT scans in the same study using PCD-CT. Overall image quality, sharpness, and noise, as well as visual emphysema pattern (no, trace, mild, moderate, confluent, and advanced destructive emphysema; as defined by the Fleischner Society), were independently assessed by 2 experienced radiologists for low- and x-ray dose images, followed by an expert consensus read.
Efficacy of Extranasal Neurostimulation for Patients With Neuropathic Corneal Pain: A Pilot Study.
Cornea
October 2024
Center for Translational Ocular Immunology, Department of Ophthalmology, Tufts Medical Center and Tufts University School of Medicine, Boston, MA; and.
Purpose: Neuropathic corneal pain (NCP) has been recognized as a distinct disease, yet treatment options remain limited. The aim of this pilot study was to explore the effectiveness of extranasal neurostimulation (EXNS) as a potential pain relief strategy for individuals with the peripheral component of NCP.
Methods: A retrospective study was performed to identify patients who were diagnosed with refractory peripheral or mixed NCP and subsequently underwent a single session of EXNS.
Chemoimmunotherapy-Resistant Ocular Surface Squamous Neoplasia Managed With I-125 Brachytherapy.
Cornea
October 2024
Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL.
Purpose: The purpose of this study was to report the management of chemoimmunotherapy-resistant ocular surface squamous neoplasia (OSSN) with iodine-125 (I-125) brachytherapy.
Methods: A 36-year-old man presented to the clinic with biopsy-proven OSSN that covered ∼70% of the corneal surface and extended to the 6 o'clock position of the inferior limbus of the OS. The visual acuity was 20/20 in the OD and 20/40 in the affected OS.
