an. 4, 2017 -- Scientists say they've identified a new organ in the body -- a swath of tissue dubbed the mesentery that connects the intestine to the abdomen and holds everything in place. For years, anatomical experts have thought the organ was composed of several different segments of tissue, as opposed to being one single structure, according to Discover magazine. Since an organ must be one structure that performs a vital function, it was not deemed worthy of organ status. But recent research from doctors at the University Hospital Limerick in Ireland shows that the mesentery is actually one single band of tissue, the magazine reported Tuesday. It begins at the pancreas and wraps around the small intestine and colon. Its purpose: to hold these organs in position so they can perform their respective functions. "Without it you can't live," lead researcher Dr. J. Calvin Coffey, a colorectal surgeon at Limerick, told the magazine. "There are no reported instances of a Homo sapien living without a mesentery." "Understanding how and why our digestive system is arranged the way it is could be crucial to our understanding of diseases like Crohn's and irritable bowel syndrome," Coffey added. "There are a lot of diseases that we are stalled on, and we need to refresh our approach to these diseases," Coffey said. "Now that we've clarified its [the mesentery's] structure, we can systematically examine it. We're at a very exciting place right now." The discovery was published recently in the Lancet Gastroenterology & Hepatology journal.

Intramedullary nailing of the tibia with suprapatellar entry and semi-extended positioning makes it technically easier to nail the proximal and distal fractures. The purpose of this article was to describe a simple method for suprapatellar nailing (SPN). A step-by-step run through of the surgical technique is described, including positioning of the patient. There are as yet only a few clinical studies that illustrate the complications with this method, and there has been no increased frequency of intraarticular damage. Within the body of the manuscript, information is included about intraarticular damage and comments with references about anterior knee pain.

Key facts

Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease.
The virus is transmitted through contact with the blood or other body fluids of an infected person - not through casual contact.
About 2 billion people worldwide have been infected with the virus and about 350 million live with chronic infection. An estimated 600 000 persons die each year due to the acute or chronic consequences of hepatitis B.
About 25% of adults who become chronically infected during childhood later die from liver cancer or cirrhosis (scarring of the liver) caused by the chronic infection.
The hepatitis B virus is 50 to 100 times more infectious than HIV.
Hepatitis B virus is an important occupational hazard for health workers.
Hepatitis B is preventable with a safe and effective vaccine.

-----------------------------------
Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a major global health problem and the most serious type of viral hepatitis. It can cause chronic liver disease and puts people at high risk of death from cirrhosis of the liver and liver cancer.

Worldwide, an estimated two billion people have been infected with the hepatitis B virus (HBV), and more than 350 million have chronic (long-term) liver infections.

A vaccine against hepatitis B has been available since 1982. Hepatitis B vaccine is 95% effective in preventing HBV infection and its chronic consequences, and is the first vaccine against a major human cancer.
