Ultrasound guidance for femoral artery catheterization superior to palpation technique in pediatric patients.
"Ultrasound-guided femoral arterial cannulation in children when performed by anesthesia residents is superior to the palpation technique based on the reduction of the time taken for attempted cannulation and the number of attempts, and improvement in first attempt success," the authors wrote.

Hepatitis E virus infection can cause acute acalculous cholecystitis
From this case report two important clinical observations can be made: (1) HEV can cause acalculous cholecystitis as an extrahepatic manifestation, and (2) the cholecystitis can resolve without antibiotic treatment.

Ultrasound Opens the Brain to Promising Drugs
The brain’s built-in protection system, the blood-brain barrier, also prevents potentially lifesaving drugs from getting in, but maybe not for much longer. A French neurosurgeon has used an implantable ultrasound device to open the blood-brain barrier to treat glioblastoma with chemotherapy.

WHO experts say Zika may cause a wider range of congenital abnormalities than previously thought
"Existing evidence and unpublished data shared with WHO highlight the wider range of congenital abnormalities probably associated with the acquisition of Zika virus" including spasticity, seizures, irritability, feeding difficulties, eyesight problems and evidence of severe brain abnormalities.

Researchers Seek to Image Gut Bacteria with Sound Waves
Certain photosynthetic single-celled organisms develop proteins that form gas-filled structures. The researchers plan to genetically engineer gut bacteria to produce these proteins, essentially causing the bacteria to produce ultrasound contrast agents within the cell.

Police won't lay charges against entertainment ultrasound service that issued identical photos to mothers
Police have no plans to lay charges against a Pickering, Ont., ultrasound clinic that issued the wrong images to more than 20 parents, saying investigators found it was an honest mistake caused by a computer glitch. There are no regulations governing non-medical ultrasounds in Canada.

Combining ultrasound and MRI is more effective for elbow diagnosis than either alone
Combining ultrasound and MR arthrography to evaluate baseball players presenting with medial elbow pain provides higher accuracy in diagnosis of ulnar collateral ligament (UCL) tears over either modality alone, according to a study published in Radiology.

How accurate is fetal ultrasound for predicting sequelae of cytomegalovirus infection?
Anomalies were detected in 37.7%, and were confirmed by autopsy or postnatal clinical evaluation in 73.9%. Autopsy or postnatal clinical evaluation also detected Cytomegalovirus-related anomalies in 55% of infants with normal fetal ultrasound evaluations.

LG launches TVs that use ultrasound to repel mosquitoes
South Korean LG has launched the Mosquito Away TV in India. They previously launched air conditioners that use the same technology, emitting 30-100kHz ultrasound to repel the insects. LG says the technology is safe but prior research has questioned effectiveness of the approach.

Knee osteoarthritis and lower back pain associated with poor outcome for ultrasound-guided trochanteric bursa injection
This retrospective chart review study suggests that assessment of these clinical factors should be incorporated into the evaluation and counseling of patients with GTPS who are candidates for ultrasound-guided trochanteric bursa injection.

Mirabilis Medica raises $5.2m for ultrasound-based uterine fibroid ablation system
The company’s Mirabilis system is designed to use ultrasound to both provide imaging and ablation during procedures to remove uterine fibroids. The device uses conventional imaging ultrasound to locate the fibroid and then switches to high-intensity ultrasound to ablate the tissue with heat.

Pain-free ultrasonic device measures brain pressure
The Vittamed device is a mask that covers the eyes and has a Doppler ultrasound transducer mounted over one eye. Pressure is applied to the tissues around the eye while Doppler flow measurements are made of the blood flow in the intracranial and extracranial segments of the ophthalmic artery.

Automated breast ultrasound comes up a winner in dense-breast screening
Study shows that women with dense breasts are significantly better served when imaged with a combination of screening mammography and supplemental 3D automated breast ultrasound (ABUS) than when they’re imaged with screening mammography alone.

Should ultrasound surveillance be recommended for patients with testicular microlithiasis?
Recent recommendations do not support such surveillance when no other risk factors (family history, infertility, and so on) are prevalent. The authors conclude "all that is recommended is routine monthly testicular self-examination".
