Customized gene chip offers clues to prognosis in cases of neuroblastoma

Rather than covering the entire genome, the microarray focuses on suspect regions of chromosomes for signs of deleted genetic material known to play a role in the cancer.

Strategic analyses of European In-Vitro cancer diagnostics market - Cancer research yields promising results

Every year, nearly one in four Europeans - a total of almost one million people - dies from cancer, giving Europe the dubious distinction of having amongst the highest cancer-related mortality rates in the world. Even as cancer remains a difficult disease to diagnose, often resulting in either poor diagnosis or misdiagnosis, the number of new cancer cases is set to double by 2020.

Diagnostic imaging gets cardiovascular eye

Imaging has become a heated topic, embroiling cardiologists and more than 20 other medical specialists in a debate about tests selected and who performs and interprets them. In San Francisco on August 11-13, the American College of Cardiology is tackling this tough topic in its first-annual Integrated Cardiovascular Imaging Conference.

Evaluation of sexual abuse in children takes special skills

More than 88,000 children in the United States were confirmed victims of sexual abuse in 2002. Studies have suggested that each year approximately one percent of children experience some form of sexual abuse, resulting in the sexual victimization of 12 to 25 percent of girls and 8 to 10 percent of boys by 18 years of age.

Customized gene chip will offer clues to prognosis in cases of neuroblastoma

Genetics researchers have developed a customized gene chip to rapidly scan tumor samples for specific DNA changes that offer clues to prognosis in cases of neuroblastoma, a common form of children's cancer.

Study finds right-brain strokes harder to diagnose

According to a new German study, the findings suggest that because of differences in symptoms, strokes affecting the right side of the brain may be under diagnosed compared with to those affecting the left side.

Possible early warning system for heart problems

By using sound waves Mayo Clinic researchers have described subtle changes in the motion of the heart that are measurable by ultrasound and may improve understanding of heart function, and possibly be a noninvasive aid in predicting impending heart damage including heart attacks.

Discovery could improve the early diagnosis of breast and ovarian cancers through a simple blood test

Scientists from the Uppsala Branch of the Ludwig Institute for Cancer Research (LICR) have made a promising discovery that could improve the early diagnosis of breast and ovarian cancers through a simple blood test.

Positron emission tomography (PET) imaging can identify effectiveness of chemotherapy early in high-risk breast cancer patients

The effectiveness of chemotherapy in patients with advanced breast cancer can be evaluated earlier by using 18F-FDG positron emission tomography (PET) imaging over other conventional imaging procedures, according to an article in the July issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine.

Scientists have identified the first genetic mutations that cause the aorta to widen, tear and rupture

Finding biological markers that flag aneurysm, a bulging of the aorta that leads to dissection, a lengthwise separation of tissues in the artery wall, is critically important for early diagnosis.

Fragile X-associated tremor/ataxia syndrome difficult to diagnose

Fragile X-associated tremor/ataxia syndrome can be difficult to diagnose and should have guidelines for diagnostic testing, according to a study in the July 26 issue of Neurology, the scientific journal of the American Academy of Neurology. A second study found chemotherapy aggravated symptoms in one woman's case.

Rates of breast biopsy remained stable over a 12 year period even as mammogram use increased

Rates of breast biopsy (removal of tissue for diagnostic evaluation) remained stable over a 12 year period even as mammogram use increased and new and less invasive biopsy techniques were introduced, according to a study in the July 25 issue of Archives of Internal Medicine.

Percutaneous core-needle biopsy, provides samples of tissue suitable for accurate initial diagnosis of a solid tumor

Inserting biopsy needles through the skin appears to be a safe and reliable alternative to surgery for obtaining diagnostic samples of a suspected solid tumor in children, according to results of a study by investigators at St. Jude Children's Research Hospital.
