REVIEW
Katarzyna Czarnecka-Kujawa, Kazuhiro Yasufuku
This review provides an update on the current role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and mediastinoscopy (Med) in assessment of patients with non-small cell lung cancer (NSCLC). Invasive mediastinal lymph node (LN) staging is the major application for both of these techniques. Up until recently, Med was the gold standard for invasive mediastinal LN staging in NSCLC. However, EBUS-TBNA has shown to be equivalent, and in some studies better than Med for invasive staging of lung cancer...

AIM: To analyse the cost-effectiveness of care provided to patients in need of peripheral venous access by comparing the traditional approach with a nurse-based ultrasound-guided programme. BACKGROUND: Letting nurses insert ultrasound-guided catheters is a promising cost-saving approach, but there are few data available to document the efficiency of this type of programme. METHOD: A cost-efficiency evaluative research design was used. Data were collected over a 6-year timeframe, before and after the implementation of the nurse-based programme...

BACKGROUND: Complex Regional Pain Syndrome (CRPS) occurs due to different pathophysiological mechanisms. Presently there is no description of definitive treatment that can resolve the especially recalcitrant motor issues of disability in CRPS-1. CASE REPORT: We have herein described the successful management of motor disability with a multi-modal approach in a patient with CRPS-1 that occurred as a result of a fracture sustained in the lower end of the radius. Sensory/sudomotor/vasomotor symptoms were relieved completely by medications and stellate ganglion block, in two weeks...

Non-invasive, quantitative methods to assess the properties of biological tissues are needed for many therapeutic and tissue engineering applications. Magnetic resonance elastography (MRE) has historically relied on external vibration to generate periodic shear waves. In order to focally assess a biomaterial or to monitor the response to ablative therapy, the interrogation of a specific region of interest by a focused beam is desirable and transient MRE (t-MRE) techniques have previously been developed to accomplish this goal...

INTRODUCTION: The majority of women having planned cesarean section receive spinal anesthesia for the procedure. Typically, spinal opioids are administered during the same time as a component of multimodal analgesia to provide pain relief in the 16-24h period postoperatively. The quadratus lumborum block is a regional analgesic technique that blocks T5-L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries and may be a potential alternative to spinal opioids...

Ultrasound-guided medical interventions are broadly applied in diagnostics and therapy, e.g. regional anesthesia or ablation. A guided intervention using 2D ultrasound is challenging due to the poor instrument visibility, limited field of view and the multi-fold coordination of the medical instrument and ultrasound plane. Recent 3D ultrasound transducers can improve the quality of the image-guided intervention if an automated detection of the needle is used. In this paper, we present a novel method for detecting medical instruments in 3D ultrasound data that is solely based on image processing techniques and validated on various ex-vivo and in-vivo datasets...

Fused real-time ultrasound and magnetic resonance imaging (MRI) may be used to improve the accuracy of advanced image guided procedures. However, its use in regional anesthesia is practically nonexistent. In this randomized controlled crossover trial, we aim to explore effectiveness, procedure-related outcomes, injectate spread analyzed by MRI, and safety of ultrasound/MRI fusion versus ultrasound guided Suprasacral Parallel Shift (SSPS) technique for lumbosacral plexus blockade. Twenty-six healthy subjects aged 21-36 years received two SSPS blocks (20 mL 2% lidocaine-epinephrine [1 : 200,000] added 1 mL diluted contrast) guided by ultrasound/MRI fusion versus ultrasound...

In 2016, it is estimated 180,890 men are newly diagnosed with prostate cancer and 3,306,760 men live with prostate cancer in the United States. The introduction of multiparametric (mp) magnetic resonance imaging (MRI) of the prostate, standardised interpretation guidelines such as Prostate Imaging Reporting and Data System (PI-RADS version 2), and MRI-based targeted biopsy has improved detection of clinically significant prostate cancer. Accurate risk stratification (Gleason grade/score and tumour stage) using imaging and image-guided targeted biopsy has become critical for the management of patients with prostate cancer...

BACKGROUND: The current standard for Prostate Cancer (PCa) detection in biopsy-naïve men consists of 10-12 systematic biopsies under ultrasound guidance. This approach leads to underdiagnosis and undergrading of significant PCa while insignificant PCa may be overdiagnosed. The recent developments in MRI and Contrast Enhanced Ultrasound (CEUS) imaging have sparked an increasing interest in PCa imaging with the ultimate goal of replacing these "blind" systematic biopsies with reliable imaging-based targeted biopsies...

BACKGROUND: Regional anesthesia is commonly used in children. Our hypothesis was that percutaneous ultrasound-guided (PERC) rectus sheath blocks would result in lower postoperative pain scores compared to intraoperative (IO) rectus sheath blocks following umbilical hernia repair. METHODS: A single-institution randomized blinded trial was conducted in pediatric patients undergoing elective umbilical hernia repair. The primary outcome was mean postoperative Wong-Baker pain score...

Ultrasound-guided regional anesthesia requires the anesthesia provider to interpret new information. This article reports on the case of a 38-year-old man scheduled for a fifth metacarpal fracture repair. Ultrasound nerve examination revealed abnormal pathology of the axillary brachial plexus consisting of an increased volume of the terminal nerves of the brachial plexus. Ultrasound scanning initiated the subsequent diagnosis of multifocal motor neuropathy. Regional anesthesia was abandoned in favor of general anesthesia...

Ultrasound guidance for epidural block has improved clinical blind-trial problems but the design of present ultrasonic probes poses operating difficulty of ultrasound-guided catheterization, increasing the failure rate. The purpose of this study was to develop a novel ultrasonic probe to avoid needle contact with vertebral bone during epidural catheterization. The probe has a central circular passage for needle insertion. Two focused annular transducers are deployed around the passage for on-axis guidance. A 17-gauge insulated Tuohy needle containing the self-developed fiber-optic-modified stylet was inserted into the back of the anesthetized pig, in the lumbar region under the guidance of our ultrasonic probe...
