RIO DE JANEIRO, Aug. 31 (Xinhua) -- The Brazilian city of Rio de Janeiroe may have an unprecedented dengue fever epidemic next summer, its mayor warned on Wednesday.The increasing number of dengue fever cases in the past few months shows similarities to the months predecing the 2002 and 2008 epidemics, Mayor Eduardo Paes said."Everything points to a new cycle of the disease, certainly the worst epidemic in Rio's history," he said.In 2008, Rio registered some 250,000 cases of dengue fever, with 174 people confirmed dead from the disease. In 2002, Rio had some 290,000 dengue fever cases and 91 people died.In efforts to halt the spread of the disease, Paes has declared a state of alert and is determined to take a series of measures to eliminate the habitat of the Aedes aegypti mosquito, which transmits dengue fever through its bite.Paes also announced an increase in the number of health care units for dengue fever patients. The total cost of a dengue prevention and combat program, which is expected to last until April 2012, will reach 42 million reais (26.25 million U.S. dollars).There is no vaccine against dengue fever, but Brazilian scientists are currently working on one which will immunize against four types of the disease.

Pasting no- smoking notices at every public place will be mandatory.According to The Himalayan Times daily, the ban covers sale of tobacco products and single sticks within a 100-meter radius of educational and health institutions, children's homes, child care centers and home for elders.Anyone selling tobacco products to persons under the age of 18 years and pregnant women will be fined.The Act also prohibits advertising and sponsoring programs in the name of tobacco-related products through media. Offenders will be fined.The government's mass awareness campaign will cover the entire country to ensure effective implementation of the Act.

LOS ANGELES, June 5 (Xinhua) -- A latest study has found no evidence that screening for ovarian cancer may reduce the risk of dying from the disease, it was reported on Sunday.Screening, however, does increase the likelihood of unnecessary invasive procedures, according to researchers at the University of Utah.The researchers presented their findings at an on-going meeting of the American Society of Clinical Oncology in Chicago, The Los Angeles Times said.Researchers studied 78,216 women, ages 55 to 74, who participated in the National Cancer Institute's Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Half of the women received the usual care from their OB-gyns, and half received a CA 125 screening every year for six years and an ultrasound every year for four years. They were then followed for a maximum of 12 years.The researchers observed 212 ovarian cancers in the screened group and 176 in the normal care group. There were 118 ovarian cancer deaths in the screened group and 100 in the normal care group. The differences were not statistically significant. Overall, there were 2,924 deaths from all causes in the screened group and 2,914 in the normal care group.But the researchers also observed that 3,285 women had false- positive diagnoses from the screening. Among those, 1,080 underwent surgery that included an oophorectomy (surgical removal of one or both ovaries). Fifteen percent of those who had surgery developed major complications as a result. Overall, 1,771 women in the screened group (7.7 percent) had an oophorectomy, compared with 1,304 in the normal care group (5.8 percent)."We conclude that annual screening for ovarian cancer ... does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms," the researchers said in the study.New data presented at the meeting also showed that the widely used cancer drug Avastin can improve treatment of ovarian cancer, The Times said.About 21,880 American women are diagnosed with ovarian cancer each year and about 13,850 die from it, according to the American Cancer Society. Because it produces few symptoms, the disease is typically not diagnosed until it has become advanced and spread throughout the body. As a result, five-year survival is only about 30 percent, and the disease is one of the five most deadly cancers among women. Being able to detect the cancer at an earlier stage when it might be more curable could thus, theoretically, improve the survival rate.The tests most commonly used to detect ovarian cancer include a transvaginal ultrasound to look for tumor masses and a blood test that screens for increased levels of a tumor marker called CA 125.

MOSCOW, Aug. 7 (Xinhua) -- A state of emergency has been imposed in a district in the Krasnodar Region in south Russia amid an out break of the African swine fever, the regional emergencies center said on Sunday.The emergencies center told local reporters that the African swine fever virus (ASFV) was found in a private farm where 15 pigs died of the disease, but the source of the infection is still unclear.Local authorities said some 12,000 pigs in and around the Krylovskaya village, some three km away from the private farm, are being culled, 50 of which have already died of the ASFV in recent days.In April, the regional emergencies has temporarily declared a state of emergency in the Labinsky district in the region, as the ASFV was found at a livestock farm. 85 pigs were culled at the farm.
