The purpose of this prospective study was to investigate the usefulness of acoustic radiation force impulse (ARFI) elastography of the pancreas for predicting postoperative pancreatic fistula occurrence after pancreatic resection. ⋯ This preliminary study showed the potential feasibility of a clinical application of ARFI elastography in preoperatively predicting postoperative pancreatic fistulas after pancreaticoduodenectomy. Investigation of this method in larger studies is needed.

The purpose of this series was to describe the sonographic findings of tuberculous vasitis. We conducted a retrospective analysis of 3 cases of tuberculous vasitis. The following grayscale and color Doppler sonographic features were analyzed: location, echogenicity of the lesion, epididymal or testicular involvement, presence of hydrocele, and blood flow within the lesion. ⋯ On color Doppler sonography, no blood flow was identified within the lesions of the vas deferens. All 3 patients had tuberculous epididymitis in addition to tuberculous vasitis. Tuberculous vasitis presents with infection along with tuberculous epididymitis, and it appears as a heterogeneously hypoechoic lesion in the scrotal segment of the vas deferens adjacent to the epididymal tail.

The purpose of this study was to compare sonographically guided vascular access using standard and echo-enhanced needles in a variety of tissue-simulating vascular phantoms. ⋯ Echo-enhanced needles decreased the incidence of posterior wall punctures when compared to standard needles during sonographically guided vascular access. However, there were no significant differences in other sonographically guided vascular access metrics.

To investigate the distribution pattern of sonographically guided iliopsoas (IP) injections in an unembalmed cadaveric model. ⋯ Sonographically guided IP injections using an in-plane, lateral-to-medial technique place injectate into the IP bursa between the IP tendon and the acetabular rim. Within the limits of this cadaveric investigation, this sonographically guided 7-mL IP "bursa" injection may provide a minimum of 50% circumferential IP tendon coverage and approximately 5 cm of cephalad and caudad flow. There does not appear to be a peritendinous space deep to the IP tendon at the acetabular rim that is both outside the bursa and amenable to sonographically guided injection. Injections into the superficial aspect of the IP using 7-mL volumes may not deliver injectate deep to the IP tendon and therefore may represent a fundamentally different injection.

Hospital-wide survey of bacterial contamination of point-of-care ultrasound probes and coupling gel.
The purpose of this study was to determine the hospital-wide incidence of bacterial contamination of point-of-care (bedside) ultrasound probes and coupling gel at a single academic medical center to predict the risk of nosocomial spread of infection. ⋯ Bacterial contamination of point-of-care ultrasound probes and coupling gel is low at this single academic medical center and involves nonpathogenic organisms only.
