PURPOSE To evaluate the benefit of various surgical methods to address pseudophakic negative dysphotopsia. SETTING Private practice, Los Angeles, California, USA. DESIGN Interventional case series. METHODS The following 4 surgical methods were used to treat negative dysphotopsia: secondary piggyback intraocular lens (IOL) implantation, reverse optic capture, in-the-bag IOL exchange, and i...

The therapeutic use of ultrasound contrast agents (UCAs) is an emerging methodology with high potential for enhanced directed therapeutic gene, bioactive gas, drug, and stem cell delivery. Ultrasound-targeted microbubble destruction has already demonstrated feasibility for plasmid DNA delivery. Similarly, therapeutic ultrasound for thrombolysis treatment has been taken into the clinical setting...

BACKGROUND AND PURPOSE A recent novel application of ultrasound therapy is the treatment of bone fractures. The aim of this study was to investigate the effect on fracture repair of ultrasound produced by a conventional therapeutic ultrasound unit as used by physical therapists. SUBJECTS AND METHODS Bilateral midshaft femur fractures were created in 30 adult male Long-Evans rats. Ultrasound t...

OBJECTIVE Evidence is currently lacking for guidance on ultrasound transducer configuration (shape) when imaging muscle to measure its size. This study compared measurements made of lumbar multifidus on images obtained using curvilinear and linear transducers. METHOD Fifteen asymptomatic males (aged 21-32 years) had their right lumbar multifidus imaged at L3. Two transverse images were taken ...

Therapeutic ultrasound is one of the most common treatments used in the management of soft tissue lesions, which constitute the majority of rheumatic complaints. Although many laboratory-based research studies have demonstrated a number of physiological effects of ultrasound upon living tissue, there is remarkably little evidence for benefit in the treatment of soft tissue injuries. This may be...

The study investigated the relationship between ultrasound elastography (USE) scoring and myofibroblast distribution with expression features of α-SMA +/CD34- in patients of Uyghur and Han ethnicities with breast masses in Xinjiang, China. The data was used to evaluate its clinical significance in the early diagnosis of breast cancer. A total of 300 patients with breast masses were included in ...

Objectives. To evaluate clinical outcomes following transvaginal catheter placement using transabdominal ultrasound guidance for management of pelvic fluid collections. Methods. A retrospective review was performed for all patients who underwent transvaginal catheter drainage of pelvic fluid collections utilizing transabdominal ultrasound guidance between July 2008 and July 2013. 24 consecutive...

To consider microalgae lipid biofuel as a viable energy source, it is a necessity to maximize algal cell lysis, lipid harvest, and thus biofuel production versus the energy used to lyse the cells. Previous techniques have been to use energy consumptive ultrasound waves in the 10-40 kHz range in a stationary exposure environment. This study evaluated the potential of using 1.1 MHz ultrasound pul...

PURPOSE We evaluate the feasibility and potential advantages of ProACT system implantation using transrectal ultrasound rather than fluoroscopy for guidance. MATERIALS AND METHODS The transrectal ultrasound guided procedure was done between June and October 2005 in 7 patients with a mean age of 68.4 years (range 53 to 76) with mild to severe stress urinary incontinence after laparoscopic tran...

OBJECTIVE To evaluate the clinical role of noncontact, low-frequency ultrasound therapy (MIST Therapy System; Celleration, Eden Prairie, Minnesota) in the treatment of chronic lower-extremity wounds. DESIGN A retrospective observational study. SETTING A multidisciplinary, vascular wound-healing clinic. PATIENTS One hundred sixty-three patients who received MIST Therapy plus standard of ca...
