Computed tomography aids scleroderma lung disease prognosis

High-resolution computed tomography is useful for the prognosis of patients with systemic scleroderma-related interstitial lung disease, research shows.

Research roundup: Financial impact of reducing surgical complications; Pay for performance to doctors, hospitals yields mixed results

The authors write: "We found that if a hospital's surgical inpatient volume is not growing, such a program results in negative cash flow. We also found that if a hospital's surgical volume is growing, and if the hospital can sufficiently reduce the average length-of-stay for surgical patients without complications, the cash flow could be positive. We recommend that hospitals with limited growth prospects that are nonetheless contemplating a surgical complication reduction program establish agreements with payers to share in any savings generated by the program."

Quick, cheap eye scan can predict brain damage in people with multiple sclerosis

An inexpensive, five-minute eye scan can accurately assess the amount of brain damage in people with the debilitating autoimmune disorder multiple sclerosis (MS), and offer clues about how quickly the disease is progressing, according to results of two Johns Hopkins studies.

$Arthroscopy best for scaphoid fracture assessment$

Arthroscopy best for scaphoid fracture assessment

Research shows that radiographs and computed tomography cannot replace arthroscopy for the diagnosis of unstable and displaced fractures of the scaphoid wrist.

AIUM to host Ultrasound First Forum on Nov. 12

The American Institute of Ultrasound in Medicine (AIUM) will host an Ultrasound First Forum on November 12, 2012, in New York, New York. The forum will address the expanding role of ultrasound imaging as a "first" imaging examination and will be devoted to encouraging the use of ultrasound as a safe, effective, and affordable alternative to other diagnostic imaging modalities where scientific evidence supports its appropriateness.

Novel neuroimaging technique reveals evidence of cocaine-induced cerebral microischemia

Researchers from the Department of Biomedical Engineering at Stony Brook University have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels - including small capillaries - of the brain.

Ischemic preconditioning tested in stroke patients

Inducing repeated brief ischemia in the arms may reduce the rate of recurrent stroke in patients with symptomatic intracranial arterial stenosis, a small clinical study shows.

CT technique could improve COPD classification

The parametric response map technique can be used in chronic obstructive pulmonary disease to distinguish between disease subtypes, say US researchers.

Smartphone stroke assessment shows promise

A smartphone application that assists vascular neurologists with the assessment of possible stroke patients shows excellent agreement with the interpretations of other radiologists and independent, blinded adjudicators, say researchers.

Parametric response mapping could improve diagnosis and treatment of COPD

A new approach to lung scanning could improve the diagnosis and treatment of a lung disease that affects approximately 24 million Americans and is the country's third-highest cause of death.

Mouse genome consists of 10-nm chromatin fibres

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings are published in EMBO reports, reveal that the mouse genome consists of 10-nm chromatin fibres but did not find evidence for the wider 30-nm fibres that were previously thought to be important components of the DNA architecture.

IDIBELL, Universitat Politècnica de Catalunya patent novel system to improve lung cancer diagnosis

The system guides physicians by describing the best bronchoscope route from the trachea to a peripheral lung lesion. It avoids futile examinations and minimises potential risk for the patient.

Researchers create 3D model of the pulmonary acinus

Amidst the extraordinarily dense network of pathways in a mammal lung is a common destination. There, any road leads to a cul-de-sac of sorts called the pulmonary acinus. This place looks like a bunch of grapes attached to a stem (acinus means "berry" in Latin).

F-18-FLT-PET predicts early response to chemoradiotherapy in head and neck cancer

Determining the optimal treatment course and predicting outcomes may get easier in the future for patients with head and neck sqaumous cell carcinomas (HNSCCs) with the use of an investigational imaging agent.

Pediatric lower respiratory illness continues after hospital discharge

One-third of children hospitalized with severe lower respiratory illness have chronic moist cough a year after discharge, research shows.

Optics Express publishes new paper on smart micromanipulation aided robotic-surgical tool

Even the most skilled and steady surgeons experience minute, almost imperceptible hand tremors when performing delicate tasks. Normally, these tiny motions are inconsequential, but for doctors specializing in fine-scale surgery, such as operating inside the human eye or repairing microscopic nerve fibers, freehand tremors can pose a serious risk for patients.

New nanotechnology detects micrometastases in mouse models of breast cancer

Malignant cells that leave a primary tumor, travel the bloodstream and grow out of control in new locations cause the vast majority of cancer deaths. New nanotechnology developed at Case Western Reserve University detects these metastases in mouse models of breast cancer far earlier than current methods, a step toward earlier, life-saving diagnosis and treatment.

Advanced optics system noninvasively maps out network of tiny blood vessels beneath the skin

The trained eye of a dermatologist can identify many types of skin lesions, but human sight only goes so far. Now an international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients' skin, potentially revealing telltale signs of disease.
