  • Ultrasound of Peripheral Nerve and Muscle
    ULTRASOUND OF PERIPHERAL NERVE AND MUSCLE Steven Shook, MD Cleveland Clinic Cleveland, OH INTRODUCTION Advances in field of ultrasound over the past twenty years have generated increasing interest in utilizing the technology in neuromuscular assessment and diagnosis. High-resolution ultrasound offers a noninvasive, real- time, static and dynamic examination of the peripheral nervous system, yielding information which complements the neurological examination, electrodiagnostic testing (EDX), and other established imaging modalities such as Magnetic Resonance Imaging (MRI). ULTRASOUND BASICS Ultrasonography involves transmitting sound-wave pulses into tissue and analyzing the temporal and acoustic properties of the reflected wave, or echo. Echoes occur at tissue interfaces. Reflected energy is a product of the difference in adjacent tissue densities (acoustic impedance), as well the angle of the ultrasound beam (angle of incidence) relative to the interface.(1) A fraction of a transmitted sound-wave energy is reflected whenever there is a change in acoustic impedance within tissue. Larger differences in acoustic impedance result in more profound reflection. Unreflected sound travels deeper into the tissue, generating echos from layers at a greater depth. A portion of the ultrasound energy never returns to the transducer, either being transformed into heat (absorption), refracted or scattered at nonperpendicular tissue interfaces. When the sound wave encounters a significantly different tissue density, analysis of deeper structures is not possible. For example, ultrasound cannot evaluate structures deep to air- filled cavities or bone due to the acoustic impedance of these regions.(2) An ultrasound probe (transducer) is capable of both emitting and receiving these pulses and converting them into electrical signals for analysis.

A report of a suspected ADR to the Yellow Card scheme does not necessarily mean that it was caused by the vaccine, only that the reporter has a suspicion it may have. Underlying or previously undiagnosed illness unrelated to vaccination can also be factors in such reports. The relative number and nature of reports should therefore not be used to compare the safety of the different vaccines. All reports are kept under continual review in order to identify possible new risks.

Abstract Objective: Ulnar tunnel syndrome (UTS) is an uncommon ulnar neuropathy. Clinical and electrophysiological diagnosis of UTS is difficult. The purposes of this study were to assess the diagnostic value of the nerve conduction measurements for UTS caused by ganglion, and to investigate the electrophysiological features of UTS.

For peripheral mononeuropathy, second only to carpal tunnel example, some investigators performed ulnar nerve syndrome in incidence.

  • Is Ulnar Nerve Entrapment at Wrist
    ORIGINAL PAPER International Journal of Occupational Medicine and Environmental Health 2017;30(6):861 – 874 https://doi.org/10.13075/ijomeh.1896.00970 IS ULNAR NERVE ENTRAPMENT AT WRIST FREQUENT AMONG PATIENTS WITH CARPAL TUNNEL SYNDROME OCCUPATIONALLY EXPOSED TO MONOTYPE WRIST MOVEMENTS? MAGDALENA LEWAŃSKA and JOLANTA WALUSIAK-SKORUPA Nofer Institute of Occupational Medicine, Łódź, Poland Department of Occupational Diseases and Environmental Health, Out-patient Clinic of Occupational Diseases Abstract Objectives: Association between carpal tunnel syndrome (CTS) and ulnar nerve entrapment at wrist remains controversial. The aim of the study has been to investigate the prevalence of Guyon’s canal syndrome amongst patients diagnosed with the CTS, occupationally exposed to repetitive wrist movements. Material and Methods: The retrospective analysis of 310 pa- tients (268 females, 42 males) representing the mean age of 52±7 years old hospitalized for the suspected occupational CTS was performed. Results: In the analyzed cohort, 4 patients had undergone decompression of the Guyon’s canal in the right limbs. Nerve conduction studies (NCS) in the ulnar nerves performed during the hospitalization of those patients did not show any abnormalities. Nerve conduction studies revealed signs of the ulnar neuropathy (UN) at the wrist affecting exclusively sen- sory fibers for 6 patients. Only those 4 patients who had undergone the operation suffered from clinical symptoms of the UN before the surgery. In the case of the remaining patients, despite the NCS changes, signs suggestive of the UN at the wrist were not detected. In the case of the patients with the occupational CTS, no signs of the ulnar nerve dysfunction were recorded.

Background: Our study investigates the feasibility of using quantitative evaluation for nerve entrapment visualization by shear wave elastography (SWE) in diabetic rats. Methods: A total of 24 male Sprague-Dawley (SD) rats were included in this study. Before injection of streptozotocin (STZ), the experimental groups were assigned as the diabetic nerve compression (DNC) group (DNC, n=18) and the control group (CON, n=6). The DNC model was created by wrapping a silicone tube around the nerve, and then the DNC group was divided into the DNC 2-week (DNC2W, n=6), 4-week (DNC4W, n=6), and 8-week (DNC8W, n=6) groups according to the different duration time of sciatic nerve compression. The nerve stiffness was detected by SWE. Meanwhile, motor nerve conduction velocity (MNCV) was detected.
