Point-of-Care Ultrasound is a method of performing a rapid clinical ultrasound, with the aim of responding to a clinical question immediately. This is not an ultrasound performed systematically as the radiologists do, nor does it pretend to replace it. It is useful in some kind of screening (abdominal aortic aneurysm) and is of special interest in ultrasound-guided procedures (joint infiltration by injection). It allows to adapt the derivations, minimising the uncertainty, ruling out certain pathologies due to its high diagnostic precision...

BACKGROUND: Many clinicians require a solid understanding of the anatomical areas supplied by specific peripheral nerves. Virtually all pertinent medical textbooks claim that the entire (palmar and dorsal) surface of the hand is supplied by three (median, radial, and ulnar) nerves and that each of these covers a well-defined area. This study was designed to evaluate the sensory-distribution pattern of peripheral nerves in the hand. METHODS: Twelve volunteers were enrolled and randomly allocated to have median, ulnar, or radial nerve blocks to each hand on three successive days...

Ultrasound-guided corticosteroid injection into the carpal tunnel is widely performed for the management of carpal tunnel syndrome (CTS). However, this injection may worsen the condition in patients with type 2 diabetes mellitus (DM). Polydeoxyribonucleotide (PDRN) was recently recognized as a substitute for corticosteroid due to its anti-inflammatory effects. A 41-year-old woman with type 2 DM was admitted to our rehabilitation clinic with a 1-month history of numbness and tingling in her right hand and first 3 fingers tips...

RATIONALE AND OBJECTIVES: We aimed to investigate the diagnostic accuracy with which shear wave elastography (SWE) can be used to monitor response to treatment of tendinopathies, and to compare it to conventional ultrasound (US)-imaging methods (B-mode US (B-US) and power Doppler US (PD-US)). MATERIALS AND METHODS: A prospective Institutional Review Board-approved longitudinal study on 35 patients with 47 symptomatic tendons (17 Achilles-, 15 patellar-, and 15 humeral-epicondylar) who underwent standardized multimodal US and standardized clinical assessment before and after 6 months of treatment (tailored stretching exercise, sport break, and local Polidocanol) was carried out...

Carrying weight while walking is a common activity associated with increased musculoskeletal loading, but not all individuals accommodate to the weight in the same way. Different accommodation strategies could lead to different skeletal forces, stimuli for bone adaptation and ultimately bone competence. The purpose of the study was to explore the relationships between calcaneal bone competence and biomechanical accommodation variables measured during weighted walking. Twenty healthy men and women (10 each; age 27...

BACKGROUND AND AIM: Endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS) is often indicated for advanced stage patients. Therefore it is important to prevent adverse events associated with EUS-HGS procedures and obtain long stent patency. EUS-guided antegrade stenting (AS) has been developed as an advanced technique. Thus, to prevent adverse events and achieve long stent patency, EUS-AS combined with EUS-HGS (EUS-HGAS) has been reported. The aim of the present study was to evaluate the technical feasibility and efficacy of EUS-HGAS in a multicenter, prospective study...

OBJECTIVE: Endoscopic ultrasound-guided-fine needle aspiration (EUS-FNA) is an established first-line procedure in the management of solid and cystic pancreatic masses. Lymphoma is an uncommon diagnosis in EUS-FNA of the pancreas, and it is more common for such a diagnosis to be because of secondary involvement of the pancreas by a lymphoproliferative disorder than for this to represent isolated primary pancreatic lymphoma (PPL). We present the clinical, EUS and cytological features of these lesions...

BACKGROUND AND OBJECTIVES: This dose-finding study aimed to determine the minimum effective volume in 90% of patients (MEV90) of lidocaine 1.5% with epinephrine 5 μg/mL for ultrasound-guided costoclavicular block. METHODS: Using an in-plane technique and a lateral-to-medial direction, the block needle was positioned in the middle of the 3 cords of the brachial plexus in the costoclavicular space. The entire volume of lidocaine was deposited in this location. Dose assignment was carried out using a biased-coin-design up-and-down sequential method, where the total volume of local anesthetic administered to each patient depended on the response of the previous one...

BACKGROUND: Prostate cancer is the most frequent cancer in men. The diagnosis is normally achieved by a systematic prostate biopsy; however, this is a randomized approach by which a substantial number of significant carcinomas go undetected. For this reason, in recent years imaging techniques have been continuously developed, which enable visualization and therefore targeted biopsies. STANDARD PROCEDURE: The use of systematic biopsies is a standard procedure for the detection of prostate cancer...

PURPOSE OF REVIEW: More patients will accept regional blocks if these are performed during sedation or general anesthesia. This review discusses regional anesthesia in sedated or anesthetized patients. RECENT FINDINGS: As complications of regional blocks are rare, regional anesthesia can be considered aswell-tolerated. Awake patients will notice only a minority of needle-to-nerve contacts, that renders the notion of a 'live monitor' obsolete. Using high-resolution ultrasound, the needle can be advanced to an extraepineural position for injection, thus strictly avoiding needle-to-nerve contact or intraepineural injection of local anesthetic...

BACKGROUND: Ultrasound-guided central venous catheterization (CVC) is a commonly performed procedure which carries significant risks for complications. Current models used for simulation-based teaching are expensive and may not replicate tissue feel and ultrasound qualities of human tissues. We aimed to evaluate a tissue model composed of chicken breast and balloons and compare it to a commercially available mannequin. METHODS: Forty attending physicians from four departments with extensive CVC experience were enrolled...

Percutaneous coronary intervention (PCI) of total chronic coronary occlusion (CTO) still remains a major challenge. The prevalence of a CTO has been reported to be up to 30% among patients with a clinical indication for coronary angiography. Progress has been made with further advanced interventional techniques and continuously sophisticated interventional tools. Nevertheless the number of interventions carried out to recanalize a CTO is less than 10% of all procedures. Benefits of a successful CTO recanalization include relief of angina pectoris and ischemia-related dyspnea, substantial improvement in left ventricular function and, avoidance of surgery treatment...

Cardiac motion estimation is an important diagnostic tool for detecting heart diseases and it has been explored with modalities such as MRI and conventional ultrasound (US) sequences. US cardiac motion estimation still presents challenges because of complex motion patterns and the presence of noise. In this work, we propose a novel approach to estimate cardiac motion using ultrafast ultrasound data. Our solution is based on a variational formulation characterized by the L (2)-regularized class. Displacement is represented by a lattice of b-splines and we ensure robustness, in the sense of eliminating outliers, by applying a maximum likelihood type estimator...

BACKGROUND: Reconstruction of soft tissue defects in the lower third of the leg remains challenging. Anatomical constraints limit the local options available for complex defects especially lower third of leg. Local flaps based on perforator vessels are raising interest in reconstructive surgery of the limbs. We present our experience with perforator flaps for reconstruction of soft tissue defects in the lower limb. METHODS: The study was carried prospectively and 23 patients with lower limb defects treated with various perforator flaps (both elective as well as emergency) were included in the study...

REVIEW
Bruce J Kimura
The development of hand-carried, battery-powered ultrasound devices has created a new practice in ultrasound diagnostic imaging, called 'point-of-care' ultrasound (POCUS). Capitalising on device portability, POCUS is marked by brief and limited ultrasound imaging performed by the physician at the bedside to increase diagnostic accuracy and expediency. The natural evolution of POCUS techniques in general medicine, particularly with pocket-sized devices, may be in the development of a basic ultrasound examination similar to the use of the binaural stethoscope...

Ultrasound evaluation permits the state of milk being curdled to be determined quickly and cheaply, thus satisfying the demands faced by today's dairy product producers. This paper describes the non-invasive ultrasonic method of in situ monitoring the changing physical properties of milk during the renneting process. The basic objectives of the study were, on the one hand, to confirm the usefulness of conventional non-destructive ultrasonic testing (time-of-flight and attenuation of the ultrasound waves) in monitoring the process in the case of ewe's milk, and, on the other, to include other ultrasound parameters which have not previously been considered in studies on this topic, in particular, parameters provided by the Fast Fourier Transform technique...

The Synthetic Aperture Focusing (SAF) technique makes it possible to achieve a higher and more uniform quality of ultrasound images throughout depth, as if both transmit and receive dynamic focusing were applied. In this work we combine a particular implementation of SAF, called Synthetic Transmit Aperture (STA) technique, in which a single element in turn transmits and all the array elements receive the ultrasound wave, with the Filtered-Delay Multiply and Sum (F-DMAS) non-linear beamforming algorithm that we presented in a previous paper...
