Combretastatin A4 phosphate (CA4P) is a vascular disrupting agent that rapidly shuts down blood supply to tumors. Early monitoring of tumor perfusion plays a crucial role in determining the optimal strategy to managing treatment and guiding future therapy. The aim of this study was to investigate the potential value of dynamic contrast-enhanced ultrasound (CEUS) in quantitative evaluation of tumor perfusion at an early stage in CA4P therapy. Central and peripheral perfusion of tumors was detected by CEUS pre-treatment (0 h) and 2, 12 and 48 h after CA4P injection...

INTRODUCTION: Peripherally inserted central venous catheters (PICC) are widely used in cancer patients and ultrasound-guided PICC insertion could improve success rate. The tip position of the catheter should be located at the border of lower one-third of the superior vena cava (SVC) and cavo-atrial junction. The migration is malposition at the late stage after PICCs were inserted, and catheter malposition was associated with thrombosis and other complications.After patient's informed consent, we report a case of a 66-year-old male with twice catheter migrations resulting in thrombosis after being diagnosed with cardiac cancer...

The radial nerve is the most frequently injured nerve in the upper extremity. Numerous options in treatment have been described for radial nerve injury, such as neurolysis, nerve grafts, or tendon transfers. Currently, new treatment options are arising, such as platelet-rich plasma (PRP), an autologous product with proved therapeutic effect for various musculoskeletal disorders. We hypothesized that this treatment is a promising alternative for this type of nerve pathology. The patient was a healthy 27-year-old man who suffered a deep and long cut in the distal anterolateral region of the right arm...

In diagnosing peripheral pulmonary lesions (PPL), radial endobronchial ultrasound (R-EBUS) is emerging as a safer method in comparison to CT-guided biopsy. Despite the better safety profile, the yield of R-EBUS remains lower (73%) than CT-guided biopsy (90%) due to the smaller size of samples. We adopted a hybrid method by adding cryobiopsy via the R-EBUS Guide Sheath (GS) to produce larger, non-crushed samples to improve diagnostic capability and enhance molecular testing. We report six prospective patients who underwent this procedure in our institution...

BACKGROUND: Peripheral pulmonary lesions (PPLs) pose a diagnostic challenge, and the optimal investigation in many such cases remains unclear. Computed tomography (CT)-guided percutaneous needle biopsy (CT-PNB) has been the modality of choice for such lesions with a high diagnostic accuracy but with high rates of pneumothorax. Endobronchial ultrasound (EBUS) with a radial probe is an alternate diagnostic modality with increased diagnostic yield of bronchoscopy in the evaluation of PPL...

OBJECTIVES: Although spinal cord and dorsal root ganglia stimulation may be effective for managing regional pain syndromes, a more targeted approach is perhaps more appealing for discrete anatomical structures. Chronic shoulder pain is a common musculoskeletal problem with significant socioeconomic impact. A peripheral nerve stimulation of the axillary and suprascapular nerves may prove to be effective as a long-term solution for this indication. In anticipation of the future experimental research and clinical utilization, a sound methodology for the lead placement was developed, and its feasibility is tested in a cadaveric study...

PURPOSE: The traditional technique of placing a peripheral intravenous (IV) catheter is successful in most cases on inpatient wards. However, when the traditional method fails, a central venous catheter may be placed to maintain IV access. These catheters are associated with risks including central line-associated bloodstream infection. METHODS: We evaluated the effectiveness and acceptability of an ultrasound-guided peripheral IV service to reduce the number of newly placed central venous catheters on an inpatient ward...

Samjot Singh Dhillon, Kassem Harris
Peripheral pulmonary lesions (PPLs) are generally considered as lesions in the peripheral one-third of the lung although a precise definition and radiographic anatomical landmarks separating central and peripheral lesion does not yet exist. The radiographic detection of such lesions has increased significantly with the adoption of lung cancer screening programs. These lesions are not directly visible by regular flexible bronchoscopes as they are usually distal to the lobar and segmental bronchi. Traditionally, depending on location and clinical stage at presentation, these lesions were typically sampled by computerized tomography (CT) guided needle or surgical biopsy although some centers also used ultrasound and fluoroscopy guided percutaneous needle biopsy...

Background: Umbilical hernia repair is a common pediatric surgical procedure. While opioid analgesics are a feasible option and have long been a mainstay in the pharmacological intervention for pain, the effort to improve care and limit opioid-related adverse effects has led to the use of alternative techniques, including regional anesthesia. The current study prospectively compares the analgesic efficacy of three techniques, including caudal epidural blockade, peripheral nerve blockade, and local wound infiltration, in a double-blinded study...
