Abstract

Identification of carcinoma arising in the uncinate region of the pancreas is difficult because of the peculiar topographic relationship of this lesion with adjacent structures. Among the various diagnostic procedures performed upon ten patients with this malignant lesion, superior mesenteric arteriography provided the most helpful information, including signs of invasion in the main trunk of the superior mesenteric artery and vein and in the proximal portion of the jejunal arteries. A clearer visualization of these vascular involvements was attained in the right posterior oblique projection rather than in the anteroposterior projection. On the contrary, the arterial and portal vessels belonging to the celiac territory, such as superior pancreaticoduodenal arteries, dorsal pancreatic artery, gastroduodenal artery, splenic vein and portal vein, were almost free of involvement. At laparotomy, almost all of the patients had direct extension of the tumor to the superior mesenteric vessels, forming a cancerous core in the root of mesentery. All died of cachexia within six months after a palliative surgical procedure. Serial roentgenograms of superior mesenteric artery, especially taken in the oblique projection, are the best means o...Continue Reading

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
