Ultrasound in Biomedical Engineering: Ultrasound Microbubble Contrast Agents Promote Transdermal Permeation of Drugs
This report discusses a new development in the use of ultrasound microbubble contrast agents on transdermal drug delivery. The medium surrounding the microbubbles at the optimum concentration from liquid to gel can be modified and it can still achieve the same enhancement for transdermal drug permeation as liquid medium. It was also found that under the same ultrasound power density, microbubbles of larger particle sizes can extend the penetration depths of dye at the phantom surface.

Prenatal Ultrasound Findings of Pregnancy Associated with Zika Virus Infection
Publication date: Available online 25 September 2016 Source:Journal of Medical Ultrasound Author(s): Yen-Ni Chen, Chih-Ping Chen, Chen-Ju Lin, Shin-Wen Chen The outbreak of Zika virus followed by an increase in cases of fetal microcephaly in Brazil in 2015 has raised the concern of the association of Zika virus infection with fetal microcephaly and other central nervous system (CNS) malformations. Most patients with Zika virus infection are asymptomatic. However, according to a previous report, the most common symptom in pregnant women with Zika virus infection and fetal microcephaly is rash. Reported prenatal ultras...

Pneumocardium Captured on Bedside Transesophageal Echocardiography —An Unreported Complication of Needle Thoracostomy
We describe a case of left-sided pneumocardium, identified by transesophageal echocardiography, following needle thoracostomy in a tertiary intensive care unit (ICU). Bilateral needle thoracostomy was performed during a cardiac arrest. Intracardiac arrest echocardiography demonstrated pneumocardium immediately following the procedure, with air in the left atrium (LA) and left ventricle (LV). This previously unreported consequence of needle decompression contributes to a growing body of literature that questions the value of this intervention. (Source: Journal of Medical Ultrasound)

Automatic 3D foetal face model extraction from ultrasonography through histogram processing
Publication date: Available online 10 September 2016 Source:Journal of Medical Ultrasound Author(s): Luca Bonacina, Antonio Froio, Daniele Conti, Federica Marcolin, Enrico Vezzetti Ultrasound is by far the most adopted method for safe screening and diagnosis in the prenatal phase, thanks to its non-harmful nature with respect to radiation-based imaging techniques. The main drawback of ultrasound imaging is its sensitivity to scattering noise, which makes automatic tissues segmentation a tricky task, limiting the possible range of applications. An algorithm for automatically extracting the facial surface is presented...

Use of Intrauterine Balloon Tamponade Test to Determine the Feasibility of Dilation and Evacuation as a Treatment for Early Uterine Artery Pseudoaneurysm
Publication date: Available online 27 August 2016 Source:Journal of Medical Ultrasound Author(s): Liangcheng Wang, Akiyoshi Takagi, Atsuko Kikugawa, Ayaka Kawabe, Kenichi Kuromaki Uterine artery embolization is the most common treatment for uterine vascular abnormalities. Herein, we report the successful use of dilation and evacuation as a treatment for uterine artery pseudoaneurysm. A 36-year-old woman complained of vaginal bleeding after an uncomplicated vaginal delivery. Ultrasonography showed a 12.8-mm anechoic area inside the uterus. Color Doppler revealed a to-and-fro sign, indicating an arteriovenous malforma...

Management of Amniotic Sheet with a Hammock-like Placenta
We report a case of an amniotic sheet with a hammock-like placenta located in the center of the uterine cavity. A 25-year-old woman with a history of two dilation and curettage procedures was found to have an amniotic cavity separated by a septum that contained part of the placenta. At gestational Week 32, magnetic resonance images revealed that the placenta was attached from the anterior to posterior uterine walls and resembled a hammock hanging in the center of the uterus. Subsequently, continuous intravenous administration of ritodrine hydrochloride and magnesium sulfate were given. The pregnancy was extended to Week 36...

Dynamic Ultrasound —A Useful Tool to Demonstrate Adhesions Postcarpal Tunnel Surgery
Publication date: Available online 5 August 2016 Source:Journal of Medical Ultrasound Author(s): Mei-Ting Wang, Yi-Chian Wang, Huey-Wen Liang, Geoffrey Sithamparapillai Samuel Carpal tunnel syndrome is common, and open carpal tunnel release remains the treatment of choice for cases refractive to conservative treatment. However, up to 25% of postrelease patients remain symptomatic. Our case illustrates how ultrasound examination can visualize the movements of the contents of the carpal tunnel and reveal additional pathologies. A 42-year-old patient with previous bilateral open carpal tunnel release surgeries presented...
