The needle-exchange movement has been an important development in the effort to reduce the spread of infectious diseases, especially HIV/AIDS, among drug users. A good amount of credit for the growth of the movement in the United States can be attributed to David Purchase. In fact, there are unconfirmed reports that Mr. Purchase’s needle exchange work in Tacoma, Washington beginning in 1988 was the first such offering in the United States.
A drug counselor, Mr Purchase used the $3,000 he won in a settlement after being struck by a drunk driver while on his motorcycle to begin to provide clean syringes to his clients. Sadly, Mr Purchase passed away from pneumonia on January 21 at the age of 73. His Point Defiance AIDS Project and the North American Syringe Exchange Network are responsible for keeping 15 million potentially harmful syringes off the streets each year.
This week, the New York Times reported on the development of two male circumcision devices: PrePex and Shang Ring. Both are exciting innovations that make it quicker, easier and safer to perform circumcisions on men.
Now that three studies have shown that circumcising adult heterosexual men is one of the most effective “vaccines” against AIDS — reducing the chances of infection by 60 percent or more — public health experts are struggling to find ways to make the process faster, cheaper and safer.
The goal is to circumcise 20 million African men by 2015, but only about 600,000 have had the operation thus far. Even a skilled surgeon takes about 15 minutes, most African countries are desperately short of surgeons, and there is no Mohels Without Borders.
So donors are pinning their hopes on several devices now being tested to speed things up.
Dr. Stefano Bertozzi, director of H.I.V. for the Bill and Melinda Gates Foundation, said it had its eyes on two, named PrePex and the Shang Ring, and was supporting efforts by the World Health Organization to evaluate them.
It might come to your surprise that one of the most important figures in the modern fight against malaria is none other than former Chinese leader Mao Zedong. It was his allocation of resources to assist the North Vietnamese battle both American troops and malaria that led to the discovery of artemisinin, the drug that is considered to be a major medical advancement in ending malaria.
This morning, the New York Times has a report on the history of artemisinin that is well worth reading. One idea that is posited throughout the article is if the discovery should be considered for the Nobel Prize. Weigh in in the comments section with your opinion.
Mao’s role was simple.
In the 1960s, he got an appeal from North Vietnam: Its fighters were dying because local malaria had become resistant to all known drugs. He ordered his top scientists to help.
