A strange case of upper obstructive syndrome
Aorto-duodenal fistulae constitute 80 percent of aorto-enteric fistulae, presenting with upper gastrointestinal bleeding. Rarely do they present with a history of persistent occlusive syndrome: This is the case of a 59-year-old man who underwent an aortic-bi-femoral bypass five years ago, presenting with dyspepsia and biliary vomiting.

Study highlights 10 most unnecessary and overused medical tests and treatments
Unnecessary medication. Tests that don't reveal the problem, or uncover a 'problem' that isn't really there. Procedures that have more risk than benefit. A new study highlights some of the most egregious examples of medical overuse in America. The goal is not to shame anyone, but to make healthcare more effective and efficient. (2017-10-05)

Scans spot hidden tumors in rare cancer syndrome
Researchers at Dana-Farber Cancer Institute report that full-body PET/CT scanning detected unsuspected, treatable tumors in 3 of 15 patients with Li-Fraumeni syndrome, a rare genetic cancer syndrome for which no screening tests have been recommended. They caution, however, that further, larger studies are needed to determine whether PET/CT screening is beneficial in LFS patients, who are highly susceptible to a variety of cancers from an early age because of an inborn gene mutation. (2008-03-18)

Tailoring cancer treatments to individual patients
The Center for Computational Oncology developed computer models to predict how cancer will progress in a specific individual, based on tissue, cellular and subcellular protein signaling responses. The models can predict how brain tumors (gliomas) will grow with much greater accuracy than previous models. Recently, the group began a clinical study to predict how an individual's cancer will progress after one cycle of therapy, and to use that prediction to plan the course of treatment. (2018-01-03)

Brain SPECT imaging predicts outcomes in depressed patients
New research from the Amen Clinics shows that brain SPECT (single photon emission computed tomography) imaging, a study that measures blood flow and activity patterns, identifies who is likely to get better from depression and who is not.

(2018-08-21)

A peek into lymph nodes
The vast majority of cancer deaths occur due to the spread of cancer from one organ to another, which can happen either through the blood or the lymphatic system. However, it can be tricky to detect this early enough. Researchers at Tohoku University have developed a new method that would allow doctors to detect cancers in the lymph nodes while they are still small, before they travel to other parts of the body. This can greatly increase the chances of a successful treatment. (2019-03-14)

Neural fingerprints of altruism
For at least 150 years, we know that traumatic brain injury can change several domains of behavior, impairing social behavior or memory, for instance, depending on which brain areas have been damaged. However, mapping the relation between brain areas and behavior can be tough, especially for complex behavior such as altruism. In this study, war veterans with brain lesion were studied to elucidate causal relationship between how specific brain areas are involved in social behavior. (2018-03-26)
