Cancer-Inducing Therapy

LAST month, we presented here the general picture of kidney transplantation based on the multicenter study conducted by Behzad Einollahi and colleagues as reported in the Journal of Cancer (June 2012).

This week you will know, in more detail, which immunosuppressant drugs have been causing it and briefly how. The study noted that the risk of developing malignancy in organ transplants is three-four times greater than general population.

Before 2000, patients received a two-drug maintenance regimen consisting of prednisone and cyclosporine or azathioprine (AZA); or, a triple therapy with cyclosporine, prednisone and AZA. Afterward, most patients received not just cyclosporine and prednisone but mycophenolate mofetil (MMF) as well. Today, immunosuppressive therapy is a three-drug therapy using cyclosporine/sirolimus, MMF/AZA and steroids.

The Einollahi study noted that more than half of the patients (61.3 percent) received AZA when they developed cancer. The remaining received MMF. The AZA regimen developed mostly post-transplantation lymphoproliferative disorder (PTLD); while MMF protocol had mostly resulted to Kaposi’s sarcoma (KS) tumors.

It appeared that AZA directly worsens... [READ MORE]

The "Lungs" of Our Homes

As trees slowly disappear with growing urbanization, the Rooseveltian lungs are replaced with more dangerous electrical lungs at home, many of which can damage the genetic materials of the human lungs. FRANKLIN Roosevelt said: “A nation that destroys its soils destroys itself. Forests are the lungs of our land, purifying the air and giving fresh strength to our people.” In Cebu today, however, people may have given up “fresh strength” for the material conveniences of an urbanized province. Even the more far-flung towns in the province of Cebu have already shown signs of urbanization. And it will not be long when even forests will cease to be. Nonetheless, the “lungs” have been replaced with electric air fresheners, with all the varied approaches to freshen the air—at least in the cities and the suburbs. But four Japanese researchers—three from the Iwate University (Ueda, Morioka, Iwate) Department of Veterinary Medicine and one from the National Institute of Health Services (K...

Dealing with TURP

As we age, a lot of things we easily can do when we were younger get harder to do as our bodily systems start to show problems in functioning. That's the case with TURP; and if you add the inevitable side effects of drugs used in treating it, you can only imaging how difficult old age can be. A CERTAIN practice has been common in synthetic drug treatments (so common it may be considered a cliché). You start taking a prescription for one health problem and you end up having a new one. Of course that is not true for all synthetic medications. But given lack of long-term studies in most pharmaceutical drugs today, who knows what’s going to happen in the next 20 to 30 years after taking a particular regimen. In history, many drugs have been pulled out from shelves because they later turned out to be potential killers, if not already one. The classic case is that of finasteride, a treatment used against certain complications that transurethral ...

Sex Industry Weathers Financial Crises

Varmus Christopher Forbes.com 12/29/08 14:00:05 GMT The sex industry traces back to 500 B.C., when traders from the Greek port of Miletus sold olisbos, an early version of the dildo. Today, the business of sex (including pornography) now runs into the tens of billions of dollars. (No official estimates are available; Wall Street analysts don't tend to track this stuff.) And while print and video sales are ebbing, as more free adult content has become available online, sales of un-reproducible sexual aids are still healthy. "Of course, there's concern about the economy, but right now our sales are growing," says Michael Trygstad, founder of Wet, a lubricant manufacturer in Van Nuys, Calif. "We've grown 30% this year alone. We've had to completely automate our factories to meet the tremendous demand. People are deciding to stay at home and engage in inexpensive entertainment.'' Slick marketing--and the ability to shop anonymously online--helps, too...
