RIO DE JANEIRO, Oct. 11 (Xinhua) -- The World Health Organization (WHO) on Tuesday highlighted Brazil's efforts to stop tuberculosis (TB) in its territory.According to a report released by the organization, Brazil achieved significant and sustained improvement in the fight against TB in the past years.Along with Cambodia, China, Uganda, and Tanzania, Brazil is one of the five nations which succeeded in reducing TB death rate in 2010 by half compared with 1990.The number of TB cases in the world fell for the first time in 2010, said the WHO. But with 8.8 million cases, the disease remained a major global health problem, said the organization.Although the TB death rate had significantly dropped over the years, the disease killed 1.4 million people around the world in 2010 alone.

WASHINGTON, Nov. 18 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved Erwinaze to treat patients with acute lymphoblastic leukemia (ALL), who have developed an allergy to E. coli derived asparaginase and pegapargase chemotherapy drugs used to treat ALL.Acute lymphoblastic leukemia is a type of cancer in which the bone marrow makes too many lymphocytes, a type of white blood cell. White blood cells help the body fight infection and are formed in the bone marrow.Erwinaze is injected directly into the muscle three times a week and works by breaking down one of the body's protein building blocks (the amino acid, asparagine) that is present in the blood, and is necessary for the growth of all cells. Leukemia cells cannot produce this protein building block. When a patient is treated with Erwinaze the leukemia cells die. Normal human cells are able to make enough asparagine for their own needs through biosynthesis and will not be affected by treatment with Erwinaze."The approval of Erwinaze underscores the FDA's commitment to the approval of drugs for conditions with limited patient populations with unmet medical needs using novel trial endpoints," said Richard Pazdur, director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research.Side effects associated with Erwinaze treatment include serious allergic reactions, inflammation of the pancreas, high blood levels of liver enzymes, blood clotting, bleeding, nausea, vomiting and high blood sugar.
