The ability to perform bedside thoracic ultrasound is increasingly recognized as an essential skill for thoracic clinicians, extending the clinical examination and aiding diagnostic and therapeutic procedures. Thoracic ultrasound reduces complications and increases success rates when used prior to thoracentesis or intercostal chest tube insertion. It is increasingly difficult to defend performing these procedures without real or near-real time image guidance. To assist thoracic physicians and others achieve and demonstrate thoracic ultrasound competence, the Interventional Pulmonology Special Interest Group (IP-SIG) of the Thoracic Society of Australia and New Zealand (TSANZ) has developed a new pathway with four components: (i) completion of an approved thoracic ultrasound theory and hands-on teaching course...

Background - Vesicoureteral reflux (VUR) is a common pediatric urologic disorder. After the first urinary tract infection (UTI), imaging studies are recommended, starting with a renal ultrasound (US) and voiding cystourethrography (VCUG). We propose to determine whether abnormalities found on US can help indicate the necessity of VCUG in children after the first urinary tract infection. Methods - A retrospective study included all children admitted with their first episode of urinary tract infection from January 2007 to December 2012...

INTRODUCTION: Ceritinib is a second-generation anaplastic lymphoma kinase (ALK) inhibitor. It inhibits two of the most common ALK-mutants that confer resistance to crizotinib. Ceritinib was approved by Food and Drug Administration in April 2014. However, the efficacy of ceritinib in Asian patients have not been widely studied. Decrease of malignant pleural effusion (MPE) has been rarely reported after treatment with ceritinib. CASE DESCRIPTION: A 50-year old man diagnosed with stage IV lung adenocarcinoma presented with MPE and an ALK fusion gene mutation...

Three-dimensional ultrasound has been increasingly considered as a safe radiation-free alternative to radiation-based fluoroscopic imaging for surgical guidance during computer-assisted orthopedic interventions, but because ultrasound images contain significant artifacts, it is challenging to automatically extract bone surfaces from these images. We propose an effective way to extract 3-D bone surfaces using a surface growing approach that is seeded from 2-D bone contours. The initial 2-D bone contours are estimated from a combination of ultrasound strain images and envelope power images...

OBJECTIVE: When assessing the common femoral and suprainguinal veins in patients with venous stasis, it is generally agreed that use of intravascular ultrasound (IVUS) is mandatory. This widely held dogma is reinforced by the fact that extrinsic compression of the iliac veins does not reproduce images consistent with eccentric stenosis as one sees in the arterial system. In an attempt to identify a subgroup of patients where the use of IVUS could be averted, we analyzed and carefully evaluated the images of patients who had both standard contrast venograms and IVUS examinations...

BACKGROUND: Transversus abdominis plane (TAP) block and local anesthetic wound infiltration provide analgesia after cesarean delivery. Studies comparing the 2 techniques are scarce, with conflicting results. This double-blind, randomized controlled trial aimed to compare bilateral ultrasound-guided TAP block with single-shot local anesthetic wound infiltration for analgesia after cesarean delivery performed under spinal anesthesia. We hypothesized that the TAP block would decrease postoperative cumulative fentanyl consumption at 24 hours...

OBJECTIVE: International guidelines recommend the use of ultrasound (US) and electrical stimulation (ES) for treating chronic and recurrent pressure ulcers (PUs). The methodology of these procedures, however, still needs elaboration and confirmation by clinical studies. This parallel-group, randomised, single-blind, prospective, controlled clinical trial was conducted to determine whether by using high-frequency ultrasound (HFUS) and high-voltage monophasic pulsed current (HVMPC), the rate of change in the area of older patients' PUs can be accelerated...

REVIEW
Ruth Elizabeth Brown, Srikrishna Harave
Neck masses are frequently encountered in pediatric medicine, and can present a diagnostic dilemma for the clinicians involved. There are several means by which neck masses in children can be subdivided, for example by age at presentation, anatomical location including compartments and fascia of the neck, their classical appearance when imaged, or by etiology. When imaging children the clinicians must be mindful of radiation exposure and as such ultrasound (US) is often attempted first. Cross sectional imaging can be helpful for problem solving with CT being particularly useful for assessing the patient in more acute scenarios, for example when there is airway compromise...
