Recommendations on Ultrasound-Guided Hyaluronic Acid Soft Tissue Augmentation of the Upper Face in Asians.
J Cosmet Dermatol
January 2025
Department of Oral Biology, Yonsei University College of Dentistry, Seoul, Republic of Korea.
Background: Ultrasonography allows real-time imaging of facial soft tissue during hyaluronic acid (HA) filler injections. However, there is currently limited guidance relating to ultrasound-guided HA filler placement in the upper face.
Aims: To develop guidance for the effective use of ultrasonography to improve the safety of HA filler injection procedures.
Overview and Comparison of Interscalene Block Techniques for Brachial Plexus Pain Management.
Curr Pain Headache Rep
December 2024
Department of Anesthesiology, Perioperative, and Pain Medicine, Harvard Medical School, Brigham and Women's Hospital, Boston, MA, USA.
Purpose Of Review: Peripheral nerve blocks are performed using local anesthetics that are commonly performed prior to surgery to either be the sole anesthetic and/or for postoperative pain management. Interscalene blocks are a specific type of nerve block that targets the superior and middle trunks of the brachial plexus inhibiting transmission of pain signals from the upper extremities to the central nervous system making them useful in mitigating pain following surgeries involving the shoulder, upper arm, and elbow.
Recent Findings: Previously, interscalene blocks were performed with a nerve stimulator, which is an instrument designed to generate a twitch in surrounding muscles to verify the anesthetic block was placed in the correct location.
Spectrum of Renal Tumors Other Than Renal Cell Carcinoma with Emphasis on Cytomorphological, Immunohistochemical, and Cytogenetic Study.
J Cytol
November 2024
Department of Pathology, Cytogenetics Unit, Kidwai Memorial Institute of Oncology, Bangalore, Karnataka, India.
Background: The role of fine needle aspiration cytology (FNAC) in the diagnosis of renal malignancies is established and has been getting more precise and important over a period of time. Knowledge of the pathology of uncommon renal neoplasms along with radiological and clinical correlations often aids in correct diagnosis.
Aims: The present study aims to describe the cytomorphological and immunohistochemical findings in the varied spectrum of renal tumors, other than renal cell carcinomas (RCC).
Comparing needle types and aspiration techniques in EUS-TA to optimize diagnostic efficacy and specimen quality in patients with pancreatic lesions.
Front Med (Lausanne)
December 2024
Department of Gastroenterology, Wuhan Fourth Hospital, Wuhan, China.
Purpose: In solid pancreatic lesions (SPLs), we compared the diagnostic efficacy of a 19G fine-needle aspiration (FNA) needle and a 22G ProCore fine-needle biopsy (FNB) needle, We also compared the specimen quality between the standard suction (SS) technique and heparinized wet-suction (HWS) technique.
Methods: All cases of endoscopic ultrasound-guided tissue acquisition (EUS-TA) by 19G FNA or 22G FNB for SPLs in a single-centre hospital were retrospectively reviewed. The diagnostic yield was compared between the 19G and 22G groups.
Ultrasound-guided photoacoustic image annotation toolkit in MATLAB (PHANTOM) for preclinical applications.
Photoacoustics
February 2025
Department of Biomedical Engineering, Tufts University, Medford, MA, United States.
Depth-dependent fluence-compensation in photoacoustic (PA) imaging is paramount for accurate quantification of chromophores from deep tissues. Here we present a user-friendly toolkit named PHANTOM (PHotoacoustic ANnotation TOolkit for MATLAB) that includes a graphical interface and assists in the segmentation of ultrasound-guided PA images. We modelled the light source configuration with Monte Carlo eXtreme and utilized 3D segmented tissues from ultrasound to generate fluence maps to depth compensate PA images.
