Stereotactic body radiotherapy (SBRT) is an effective method for the treatment of localized primary lung tumors. Cyberknife, a highly accurate SBRT technique, follows the target during respiratory cycles using a metallic fiducial marker (FM) previously inserted into the lesion. Various methods have been described for the placement of an FM in peripheral pulmonary lesions; however, none of these is appropriate for mediastinal or hilar tumors. The placement of FMs in central lesions to achieve accurate SBRT is particularly relevant due to their higher mobility during respiratory and cardiac cycles...

HIV-1 reservoirs are most often studied in peripheral blood (PB), but not all lymphocytes recirculate, particularly T follicular helper (Tfh) CD4(+) T cells, as well as germinal center (GC) B cells, in lymph nodes (LNs). Ultrasound-guided fine needle biopsies (FNBs) from inguinal LNs and PB samples were obtained from 10 healthy controls (HCs) and 21 HIV-1-infected subjects [11 antiretroviral therapy (ART) naive and 10 on ART]. Tfh cells and GC B cells were enumerated by flow cytometry. HIV-1 DNA and cell-associated (CA) RNA levels in LNs and PB were quantified by real-time polymerase chain reaction...

PURPOSE: Patients with diabetes mellitus (DM) type 2 may have subclinical peripheral nerve neuropathy. We performed this study to compare the differences in duration of axillary brachial plexus blocks in patients with type 2 DM and without DM (NODM). Our hypothesis was that the sensory block duration would be prolonged in patients with DM. METHODS: A total of 71 patients who were scheduled for elective forearm and/or hand surgery were enrolled in this study. Before surgery, they received ultrasound-guided axillary brachial plexus blocks with a mixture of 10 mL lidocaine 2% and 20 mL bupivacaine 0...

Claire Lyons, Andrew A Herring
Deltoid abscesses are common and painful, often a consequence of injection drug use and seen frequently in emergency departments (EDs). The required incision and drainage can be completed successfully with effective pain relief using a peripheral nerve block. The brachial plexus nerve block works well, however it is technically complex with a low, but potentially serious, risk of complications such as phrenic nerve paralysis. Selective blockade of the axillary nerve eliminates the risks associated with a brachial plexus block, while providing more specific anesthesia for the deltoid region...

INTRODUCTION: Early detection of prostate cancer (PCa) remains a challenging issue. There are studies underway aimed to develop and implement new methods for prostate cancer screening by tumor imaging and obtaining tissue samples from suspicious areas for morphological examination. One of these new methods is shear wave ultrasound elastography (SWUE). The current literature is lacking sufficient coverage of informativeness and specificity of SWUE in the prostate cancer detection, there is no clear criteria for assessing tissue stiffness at different values of PSA and tumor grade, and in prostate hyperplasia and prostatitis...

Surgical transection of sensory nerves in the treatment of intractable neuropathic pain is a commonly performed procedure. At times these cases can be particularly challenging when encountering obese patients, when targeting deeper nerves or those with a variable branching pattern, or in the case of repeat operations. In this case series, the authors describe their experience with ultrasound-guided surgical instrument placement during transection of a saphenous nerve in the region of prior vascular surgery in 1 patient and in the lateral femoral cutaneous nerve in 2 obese patients...

Patients with isolated peripheral branch neuralgia of trigeminal nerve usually receive traditional treatment such as medical therapy and interventional procedures targeting the entire trigeminal nerve or related ganglions. However, if the intractable pain is limited to a certain branch, the patient may also benefit from a peripheral and nerve-targeted interventional approach. Here, we report the management of a patient with isolated infraorbital neuralgia by ultrasound-guided infraorbital nerve block with steroid and local anesthetic combination...

Ultrasound (US) has acquired an increasing role in the assessment of joint and periarticular abnormalities in osteoarthritis (OA). It is able to image a large set of abnormalities in this disease which include both inflammatory and structural changes at different peripheral joint sites and it is helpful in guiding local procedures that can be easily and safely performed with optimal patient's tolerance. US is a feasible imaging modality that has become a bedside procedure in the rheumatology clinical practice, thus filling the gap between clinical and radiographic evaluations of patients with OA...

BACKGROUND: New catheter-over-needle (CON) technology for continuous peripheral nerve blockade has emerged, but its effect on the risk of perineural catheter tip dislocation is unknown. Less flexible catheters may be more likely to migrate away from the nerve with simulated patient movement. In the present study, we evaluated catheter tip migration between CON catheters and traditional catheter-through-needle (CTN) catheters during ultrasound-guided short-axis in-plane (SAX-IP) insertion...
