Researchers have found capsule endoscopies can be effective in detecting tumors in the small bowel that previously went undetected. According to a study released today at the 69th Annual Scientific Meeting of the American College of Gastroenterology, researchers from the Mt. Sinai Medical Center and the University of Miami School of Medicine found the capsule endosocopy detected tumors in the small bowel after patients had undergone an average of 4.6 negative evaluations. Of the tumors found, 65 percent were malignant.
The researchers studied 72 patients with confirmed small bowel tumors. Of those patients, 71 percent experienced gastrointestinal bleeding of an obscure source, and 29 percent suffered from anemia, polyposis and/or abdominal pain. These 72 patients had previously undergone 334 negative procedures (an average of 4.6 each) including 115 colonoscopies, 111 upper endoscopies, 32 small bowel follow through procedures, 24 enteroscopies, 17 CT scans, 16 enteroclysis procedures, six nuclear bleeding scans, five angiographies, five plain abdominal X-rays, one abdominal ultrasound, one Meckels scan, and one laparoscopy.
Researchers used the "M2A© Capsule" also known as the "Pill Camera" made by Given Imaging, Yoqneam, Israel. The findings from the capsule examinations included 73 small bowel tumors, one cecal tumor and one gastric tumor. Of these 65 percent were malignant, including adenocarcinomasc, carcinoids, melanomas, lymphomas and sarcomas.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
