First Cure For AIDS?
As is well known, the antirretrovirals pospone the development of AIDS but do not cure it. However in recent days a first cure in a patient with confirmed AIDS has been announced. The Huffigton Post reports:
"On the heels of World AIDS Day comes a stunning medical breakthrough: Doctors believe an HIV-positive man who underwent a stem cell transplant has been cured as a result of the procedure.
"On the heels of World AIDS Day comes a stunning medical breakthrough: Doctors believe an HIV-positive man who underwent a stem cell transplant has been cured as a result of the procedure.
Timothy Ray Brown, also known as the "Berlin Patient," received the transplant in 2007 as part of a lengthy treatment course for leukemia. His doctors recently published a report in the journal Blood affirming that the results of extensive testing "strongly suggest that cure of HIV infection has been achieved."
If the report is confirmed in other laboratories, a new dawn will appear on the otherwise bleak panorama of AIDS therapy and cure.

Good News For The Poor
The World Health Organization (WHO) has announced a donation of vaccines against Influenza H1N1 to begin distribution among the poor nations of the world beginning next month. The flu H1N1 pandemic has spread in the last few months to practically all countries of the world causing millions of human patients and more than 4500 reported deaths.
The number of cases and deaths is expected to rise in the next winter season. Fortunately an effective vaccine is now available. In the North Hemisphere the vaccine is now being applied to medical workers, pregnant women, and persons with chronic diseases who are at high risk of developing a serious illness. One dose of the vaccine is enough to prevent the disease. As it is applied around the world it will prevent thousands of deaths.

Influenza H1N1 Spreads Worldwide
Who has reported, as of July 31, 162350 confirmed cases of influenza H1N1 in 168 countries, and 1154 deaths around the world. The actual number of cases is probably much higher, because of difficulties in obtaining laboratory confirmation in many countries.
In South America, countries who are in their winter season like Chile and Argentina are experiencing a rapid increase in the number of hospitalized patients with H1N1. Schools had to be closed in some cases due to outbreaks among students. In Central America medical attention of patients with respiratory illnesses has overwhelmed the facilities in public hospitals.
Apparently the vaccine against this virus won’t be ready until the end of this year. Another unfavorable factor is the discovery of strains of the virus resistant to oseltamivir, one the antivirals used to treat flu patients.

Vaccine against Cervical Cancer
The World Health Organization approbed the second vaccine (Cervarix) against cervical cancer. The vaccine is the result of many years of research on the cause of this type of cancer. It is now accepted that a virus, papilloma virus, causes the transformation of cells that leads to cancer. The virus is sexually transmitted from men to women.
Cervical cancer is perhaps the most important type of cancer in women of the third world. It causes the death of 280,000 women, 80 % in the third world. While the first world has reduced deaths by early diagnosis (Pap tests) and treatment, such facilities are not available in poorer countries and the vaccine, if it can be obtained at a lower price, offers great hope for women around the world. The idea is to vaccinate all girls at the age of puberty.

WHO DECLARES SWINE FLU (H1N1) PANDEMIC
The World Health Organization (WHO) finally raises the level of alertness for influenza H1Ni1 from 5 to 6 and declares a World wide pandemic of flu. Seventy four countries have reported 27,737 cases and 141 deaths. Usually there is underreporting, so the real number of cases could be around 100,000. Reports come from The United States, Central and South America, Europe, Australia, the Middle East and Asia.
The last pandemic of influenza was in 1968. It was called the Hong Kong Flu and left about 1 million deaths.
What is unusual about the present pandemic is that half of the deaths have been previously healthy young people. The other half follows the pattern of people with chronic conditions or inmunocompromised.
The pressure to come out with an effective vaccine is high for the pharmaceutical companies. In the meantime the antiviral drugs such as Tamiflu and Relenza are selling by the millions of tablets. The same can be said for the face masks used now in offices, schools and hospitals.

Update on Flu Epidemy (H1N1)
The number of deaths due to the Flu Epidemy has risen to 106, 89 in Mexico, 14 in the United States, 2 in Canada and 1 in Costa Rica, while the total number of cases is over 12000 around the world. More than half of the cases are in the United States. In South America the country most affected is Chile and in Central America, Panama has reported 79 cases.
A vaccine is in the process of development and it will be several months before it is ready for the market. Meanwhile, Tamiflu and Relenza, are useful if taken within the first few days of illness. In many wountries custom officials use face masks when greeting travelers from affected countries.
The World Health Organization has declared alert 5 but is reluctant to declare a full pandemic of severity phase 6.
