Neurological diseases can be complicated by sialorrhea, an excessive flow of saliva. Patients suffering from moderate to severe sialorrhea have an impaired quality of life, often worsened by correlated complications such as aspiration pneumonia, oral infections, dental caries, and maceration of the skin. Diverse therapeutic approaches have been proposed for the treatment of sialorrhea, including surgery and the use of anticholinergic agents, with limited results and the possible occurrence of serious adverse events...

While neurostimulation-stimulation of the nervous system using electrical current-has been used to treat chronic pain, its use treating postsurgical pain has been limited. Here we report on the clinical application of a novel investigational lead to provide analgesia following total knee arthroplasty. In 5 subjects, leads were inserted percutaneously using ultrasound guidance within 0.5 to 3.0 cm of the femoral and/or sciatic nerve(s). With the delivery of current, pain decreased an average of 63% at rest, with 4 of 5 subjects having relief of >50%...

Primary squamous cell carcinoma of the pancreas (SCCP) is a rare neoplasm, given a lack of naturally occurring squamous cells within the pancreas, accounting for only 0.2% of all pancreatic cancers. The etiology is unknown. Symptomatology is non-specific and similar to other pancreatic neoplasms. No non-invasive testing can adequately rule in SCCP, and workup should proceed similarly to any pancreatic mass. Tissue sampling is required for diagnosis and guidance of further management, most commonly by endoscopic ultrasound with fine needle aspirate...

We performed stent placement under intravascular ultrasound (IVUS), without the use of contrast medium, in a male patient in his 70s who had vertebral artery origin stenosis and decreased renal function. Satisfactory dilatation was achieved without complications, and the patient remained asymptomatic at 2 years of follow-up. We now report the details of this procedure. Stent placement under IVUS guidance may be useful in patients in whom contrast medium is contraindicated.

BACKGROUND: Ultrasound guidance for venous catheter placement requires the use of both hands. An accurate and stable ultrasound image is fundamental for obtaining good quality images, consequently permitting accurate needle placement. We hypothesized that the dominant hand could be used to perform echography, leaving the non-dominant hand available for peripheral venous catheter (PVC) insertion. METHODS: Prospective, open-label, randomized, crossover study. Group 1 inserted the PVC with the dominant hand, and held the probe with the non-dominant hand in a first series of 20 insertions, and vice-versa in a second series of 20 insertions performed 11 days later...

INTRODUCTION: Saphenous nerve conduction studies are difficult, since the nerve is hard to localize and evoked responses are small. Ultrasound imaging may assist in the accurate localization and optimal positioning of surface (SE) and needle electrodes (NE). METHODS: The study population included 39 subjects and was divided into 2 groups. Group A consisted of 20 healthy subjects, while group B of 19 patients with polyneuropathies. Orthodromic conduction was measured by distal supramaximal nerve stimulation...

Central vein cannulation is one of the most commonly performed procedures in intensive care. Traditionally, the jugular and subclavian vein are recommended as the first choice option. Nevertheless, these attempts are not always obtainable for critically ill patients. For this reason, the axillary vein seems to be a rational alternative approach. In this narrative review, we evaluate the usefulness of the infraclavicular access to the axillary vein. The existing evidence suggests that infraclavicular approach to the axillary vein is a reliable method of central vein catheterization, especially when performed with ultrasound guidance...

BACKGROUND: A difficulty in computer-assisted interventions is acquiring the patient's anatomy intraoperatively. Standard modalities have several limitations: low image quality (ultrasound), radiation exposure (computed tomography) or high costs (magnetic resonance imaging). An alternative approach uses a tracked pointer; however, the pointer causes tissue deformation and requires sterilizing. Recent proposals, utilizing a tracked conoscopic holography device, have shown promising results without the previously mentioned drawbacks...
