Noninvasive Imaging Test Shown Accurate In Ruling Out Kidney Cancers
The latest in a series of studies led by researchers at Johns Hopkins Medicine shows that addition of a widely available, noninvasive imaging test called 99mTc-sestamibi SPECT/CT to CT or MRI increases the accuracy of kidney tumor classification. The research team reports that the potential improvement in diagnostic accuracy will spare thousands of patients each year in the United States alone from having to undergo unnecessary surgery.
In a recent report on ongoing work to improve kidney tumor classification, published in the April issue of the journal Clinical Nuclear Medicine, the team reports that the sestamibi SPECT/CT test—short for 99mTc-sestamibi single-photon emission computed tomography/computed tomography(CT) — adds additional diagnostic information in conjunction with conventional CTs and MRI and improves physicians’ ability to differentiate between benign and malignant kidn

ATV-Related Injuries In Children Remain Large Public Health Problem
All-terrain vehicle-related injuries remain a large public health problem in this country, with children more adversely affected than adults. According to researchers at Wake Forest Baptist Medical Center, the major risk factors for young riders also are entirely preventable.
“The injuries children sustain from ATV-related accidents are frequently more severe than injuries received from motor vehicle crashes,” said Thomas Pranikoff, MD, professor of pediatric surgical sciences at Wake Forest Baptist and lead author of the study published in the online issue of the Journal of Emergency Medicine.
Pranikoff and colleagues reviewed data from 16 published studies conducted from 2000 to 2010 on the epidemiology and risk factors among ATV-related injuries in American children.
Data from 2013, the most recent reporting year from the US Consumer Product Safety Commission, showed that there wer

New Imaging Technique Shows Effectiveness Of Cystic Fibrosis Drug
According to the Cystic Fibrosis Foundation, more than 30,000 Americans are living with the disorder. It currently has no cure, though a drug approved by the Food and Drug Administration treats the underlying cause of the disease. However, the drug’s effectiveness for each individual is unknown. Researchers from the University of Missouri School of Medicine have developed an imaging technique using a specific form of helium to measure the drug’s effectiveness. Researchers hope the finding could lead to improved therapies for cystic fibrosis and other lung conditions.
“People with cystic fibrosis have an imbalance of salt in their bodies caused by the defective CFTR protein,” said Talissa Altes, MD, chair of the Department of Radiology at the MU School of Medicine and lead author of the study. “The drug ‘ivacaftor’ targets this defective protein, but to what extent it is successful is n

Patients with common conditions such as back pain, headaches and upper respiratory infections are more likely to receive tests and services of uncertain or little diagnostic or therapeutic benefit—so-called low-value care—when they seek treatment in primary care clinics located at hospitals rather than at community-based primary care clinics, according to a nationwide study led by researchers at Harvard Medical School and the David Geffen School of Medicine at UCLA.
The key factor driving this disparity appears to be clinic location rather than clinic ownership, the research showed. Indeed, aside from referring patients to specialists slightly more often, hospital-owned community clinics delivered care otherwise similar to physician-owned community clinics.
The study findings, published in JAMA Internal Medicine, found an overreliance on referrals to specialists, CT scans, MRIs and X-r
