Emma L Rowbotham, Andrew J Grainger
OBJECTIVE: The purpose of this video article is to show sonographic anatomy at the shoulder joint relevant to impingement and to describe the diagnostic techniques that can be used to diagnose this condition. The article contains several video clips depicting both the normal and pathologic appearances of the bursa during dynamic assessment. The technique for guided injection at this location with sonographic guidance will be covered as well as pitfalls for reporting impingement. CONCLUSION: Dynamic ultrasound assessment of the shoulder is a useful adjunct to clinical assessment in the evaluation and diagnosis of impingement...

BACKGROUND AND OBJECTIVES: The retrolaminar block (RB) is used for truncal analgesia, but its mechanism of neural blockade remains obscure. We sought to learn the pattern of local anesthetic spread after thoracic RB using cadaveric models. METHODS: In 8 fresh cadavers, an ultrasound-guided T4 RB was performed with 20 mL of methylene blue 1% and bupivacaine 0.5%. For comparison, an RB at T9 in 1 cadaver and a T4 thoracic paravertebral block in another cadaver were performed...

BACKGROUND: Injection of local anesthetic into the transversus abdominis plane (TAP block) decreases systemic morphine requirements after abdominal surgery. We compared intraoperative surgeon-administered TAP block (surgical TAP) to anesthesiologist-administered transcutaneous ultrasound-guided TAP block (conventional TAP) for post-cesarean analgesia. We hypothesized that surgical TAP blocks would take less time to perform than conventional TAP blocks. METHODS: We performed a randomized trial, recruiting 41 women undergoing cesarean delivery under neuraxial anesthesia, assigning them to either surgical TAP block (n=20) or conventional TAP block (n=21)...

Background and objectives Unmyelinated C-fibres comprise the largest group of somatic afferents and have demonstrated a crucial role not only in the perception of high-threshold mechanically, thermally or chemically induced pain, but also in non-harmful low-threshold mechanical stimuli [1,2]. The objective of our study was to characterize differential sensitivity changes of C-fibre related subclasses of high-threshold and low-threshold polymodal nociceptors and low-threshold mechanoreceptors to the local anaesthetic (LA) mepivacaine during nerve block of the purely sensory lateral femoral cutaneous nerve (LFCN) in human...

PURPOSE OF REVIEW: On the basis of its various advantages and the relevant awareness of physicians, ultrasound imaging has overwhelmingly taken its place in the scientific arena. This is true both from the side of daily clinical applications and also from the side of research. Yet, ultrasound provides real-time (diagnostic) imaging and (interventional) guidance for a wide spectrum of muscle disorders. In this regard, this review aims to discuss the potential/actual utility of ultrasound imaging in particular muscle disorders, that is, sarcopenia, spasticity and fibromyalgia/myofascial pain syndrome...

Background Trigeminal neuralgia is a neuropathic disorder characterized by episodes of intense pain in the face. Drug therapy is the first choice of treatment. However, in cases where drug therapy are contraindicated due to side effects, patients can get pain relief from lengthy neurosurgical procedures. Alternatively, a peripheral trigeminal nerve block can be easily performed in an outpatient setting. Therefore it is a useful treatment option for the acute paroxysmal period of TN in patients who cannot use drug therapy...

Neurocysticercosis (NCC), the infection of the human central nervous system (CNS) with larval cysts of Taenia solium causes widespread neurological morbidity. Animal models are crucial for studying the pathophysiology and treatment of NCC. Some drawbacks of current NCC models include differences in the pathogenesis of the model and wild-type parasite, low rates of infection efficiency and lack of reproducibility. We describe a novel porcine model that recreates infection in the CNS with high efficiency. Activated oncospheres, either in a high (45,000-50,000) or low (10,000) dose were inoculated in the common carotid artery of 12 pigs by ultrasound-guided catheterization...

Renal cryoablation is becoming an established treatment option for small renal masses. It allows preservation of renal function without compromising cancer control. The technique has evolved considerably since it was first reported using liquid nitrogen over 20 years ago. We describe the modern technique for both laparoscopic and image guided renal cryoablation. Renal cryoablation is performed either laparoscopically or percutaneously depending on tumour characteristics. Common features include biopsy of the mass, protection of adjacent organs, and the use of compressed argon gas for freezing and helium for thawing...

Preclinical testing of anticancer therapies relies on relevant xenograft models that mimic the innate tendencies of cancer. Advantages of standard subcutaneous flank models include procedural ease and the ability to monitor tumor progression and response without invasive imaging. Such models are often inconsistent in translational clinical trials and have limited biologically relevant characteristics with low proclivity to produce metastasis, as there is a lack of a native microenvironment. In comparison, orthotopic xenograft models at native tumor sites have been shown to mimic the tumor microenvironment and replicate important disease characteristics such as distant metastatic spread...

The aim of this paper is to review the diagnosis and treatment of patients with a caesarean scar pregnancy (CSP), who have been managed at our unit, as well as to evaluate the effectiveness of the non-surgical treatment options. Twenty-six cases were identified over a period of 5 years and 4 months (January 2012 until April 2017). The main outcome measures were a number of previous caesarean births, a method of diagnosis of CSP, the mode of treatment and the outcome. The diagnostic criteria on the ultrasound were an empty uterine cavity and cervical canal, the presence of a gestational sac anterior to the isthmic portion of the uterus, an absent or thinned (<5 mm) myometrial thickness between the gestational sac and the bladder, with a peri-trophoblastic circulation around the gestational sac with the colour flow Doppler examination...

RATIONALE: Perineural injection with dextrose could be a novel intervention for peripheral entrapment neuropathy. However, this intervention has not been reported for treating radial nerve palsy (RNP). Here, we present a case with RNP having outstanding improvement after 2 sessions of ultrasound-guided perineural injection with 5% dextrose (D5W). PATIENT CONCERNS: A 62-year-old woman presented with difficulty and weakness in extension of her left wrist and fingers after she slept with the arm compressed against her body...

Poly n -butylcyanoacrylate (PBCA)-based hard-shell microbubbles (MB) have manifold biomedical applications, including targeted drug delivery or contrast agents for ultrasound (US)-based liver imaging. MB and their fragments accumulate in phagocytes, especially in the liver, but it is unclear if MB affect the function of these immune cells. We herein show that human primary monocytes internalize different PBCA-MB by phagocytosis, which transiently inhibits monocyte migration in vertical chemotaxis assays and renders monocytes susceptible to cytotoxic effects of MB during US-guided destruction...
