Doctors Use 3D Printing to Safeguard Baby Before Birth

Posted 6 Oct 2015 by

TUESDAY, Oct. 6, 2015 – When Michigan doctors saw a large mass on the face of a fetus late in pregnancy, they feared it might block the baby's airway at birth. The doctors didn't know what the abnormality was, or if the infant would need lifesaving care in order to breathe. Use of 3D printing technology removed the guesswork, the team reported in the Oct. 5 online edition of the journal Pediatrics. It's the first time 3D printing technology has been used in utero "to diagnose facial deformity and severity of airway risk with a newborn," said Dr. Albert Woo, a pediatric plastic surgeon at St. Louis Children's Hospital. The problem surfaced when the mother-to-be, age 22, was 30 weeks into pregnancy. The mother underwent an ultrasound, but the imaging did not provide enough information because of the way the fetus was positioned. She then underwent an MRI, but again the doctors couldn't ...

MRIs Before Breast Cancer Surgery on the Rise: Study

Posted 24 Sep 2015 by

THURSDAY, Sept. 24, 2015 – The use of MRI scans before breast cancer surgery has risen eightfold over the past decade, even though guidelines on their use in this setting are inconsistent, a new study shows. This increased use of MRI – magnetic resonance imaging – is also linked to an increase in further testing, longer wait times to surgery, a higher likelihood of a mastectomy instead of breast-conserving surgery, and a higher likelihood of having the healthy, opposite breast removed, the Canadian researchers reported. No guidelines support the routine use of preoperative MRI in women diagnosed with breast cancer, said lead researcher Dr. Matthew McInnes, of The Ottawa Hospital. Various organizations describe it as an optional procedure, as it can detect cancers that are missed with other tests. In the study, the researchers examined numerous health care databases in the province of ... Read more

MRI Helps Detect Brain Bleeding Soon After Traumatic Brain Injury

Posted 15 Sep 2015 by

TUESDAY, Sept. 15, 2015 – Military service members who undergo brain imaging soon after suffering a traumatic brain injury (TBI) may get better treatment more promptly, a new study suggests. The researchers found that MRI can help doctors detect microbleeding on the brain, which can sometimes trigger serious secondary health conditions, like brain swelling or stroke. "TBI is a large problem for our military service members and their families," said study leader Dr. Gerard Riedy, chief of neuroimaging at the National Intrepid Center of Excellence at the Walter Reed National Military Medical Center in Bethesda, Md. "We found that many of those who have served and suffered this type of injury were not imaged until many, many months after injury occurred, thus resulting in lower rates of cerebral microhemorrhage detection, which delays treatment," he added in a news release from the ...

Anti-Clotting Drug Approved For Angioplasty

Posted 22 Jun 2015 by

MONDAY, June 22, 2015 – Kengreal (cangrelor) has been approved by the U.S. Food and Drug Administration to prevent blood clots from forming during angioplasty. Angioplasty involves inflating a balloon inside a clogged artery to improve blood flow. This is typically followed by insertion of a stent, a small mesh tube designed to keep the artery open. Some 500,000 people in the United States have the procedure – medically called percutaneous coronary intervention – annually, the FDA said in a news release. Formation of a blood clot during the procedure could lead to heart attack. As with any anti-clotting drug, life-threatening bleeding is a potential side effect, the agency noted. In clinical trials, Kengreal was compared to the anti-clotting drug Plavix (clopidogrel) among more than 10,000 participants. Cases of serious bleeding, while still rare, were more common among users who ... Read more

White Matter Damage in Brain May Help Spot Early Alzheimer's

Posted 27 May 2015 by

WEDNESDAY, May 27, 2015 – Damage to the brain's white matter may be an early sign of certain types of Alzheimer's disease, according to a new study. Researchers used a specialized MRI technique called diffusion tensor imaging (DTI) to assess white matter in 53 people with three different types of Alzheimer's. Some patients had atypical forms of the disorder that affect localized parts of the brain (called focal AD syndromes). These atypical forms may cause vision and language problems. Other patients in the study had early onset Alzheimer's, which affects several areas of the brain and interferes with thinking skills such as reasoning, planning and problem solving. This is different than late-onset Alzheimer's, which develops after age 65 and is marked by progressive memory loss. All of the patients had extensive white matter damage, along with regional gray matter damage, according to ... Read more

Quitting Smoking Improves Angioplasty Outcome, Study Finds

Posted 12 May 2015 by

TUESDAY, May 12, 2015 – Patients who quit smoking when they have angioplasty – a heart blood vessel-opening procedure – have better outcomes, a new study finds. Quitting smoking was associated with less chest pain and better quality of life, researchers reported. "It's a no-brainer. Stopping smoking seems like a relatively easy way to increase your chances of getting the best outcomes from angioplasty," said senior author and cardiologist Dr. John Spertus, clinical director of outcomes research at Saint Luke's Mid America Heart Institute in Kansas City. The researchers followed more than 2,700 adults who underwent angioplasty for either a heart attack or chest pain. One year after the procedure, 21 percent of those who quit smoking when they had angioplasty had chest pain, compared with 31 percent of those who kept smoking, and 19 percent of those who never smoked or quit smoking ...
