St. Joseph’s Hospital in Phoenix offers special test for children with stroke risk

31.01.2006


Children’s Rehabilitative Services (CRS) at St. Joseph’s Children’s Health Center in Phoenix is using a special ultrasound to identify the risk for stroke in children who have sickle cell disease. The transcranial Doppler (TCD) ultrasound measures blood flow in the arteries, identifying the narrowness of the artery and assessing stroke risk.



The TCD ultrasound, which is placed at the base of the patient’s skull, measures the blood flow in the arteries. The more rapid the blood flow, the narrower the artery is, increasing the chance of developing a blood clot, which can eventually lead to a stroke.

The risk for stroke in people with sickle cell disease is greatest between the ages of two and 20 when the developing blood vessels are most susceptible to form plaques. Patients who are identified as high-risk for a stroke receive blood transfusions every three to four weeks to reduce their risk. Proper treatment can reduce the risk for stroke by approximately 90 percent.


Sickle cell disease is an inherited blood disorder that affects red blood cells. The red blood cells become sickle-shaped and have difficulty passing through small blood vessels. This can damage the wall of the artery, causing plaque to form and eventually narrowing blood flow.

"It’s critical for children with sickle cell disease to have this test," says James Frey, director of St. Joseph’s Hospital and Medical Center’s Stroke Program. "Stroke is devastating, particularly when it impairs the quality of life for someone at such an early age."

The transcranial Doppler ultrasound has been used for nearly two decades to identify medical conditions in patients such as abnormal tears in the brain and cerebral vascular disease. It was recently discovered that the test also predicts stroke risk in children who have sickle cell disease.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
