First Ever Fully cured HIV-AIDS Patient - Timothy Ray Brown

Timothy Ray Brown, a resident of San Francisco Bay Area, is possibly the first ever person to be fully cured of the incurable HIV-AIDS disease, according to scientific journal Blood. Timothy Ray Brown was tested positive for HIV around 15 years ago when he was around the age of 30. He later found out that he was also diagnosed with Leukemia. When he was still in Germany in 2007, doctors used bone marrow stem cell transplant as a method of curing his Leukemia and neither HIV nor Leukemia has been traced on him since 2008.
"I quit taking my HIV medication the day that I got the transplant and haven’t had to take any since," said Brown, who is known as 'The Berlin Patient' in medical circles.
Brown received the stem cells from a person who is apparently immune to HIV, a character that only about 1 percent of Caucasians have. Dr. Jay Levi, a leading researcher in the field of HIV-AIDS at University ofCalifornia-San Franciso (UCSF), has called this a "functional cure."
"If you're able to take the white cells from someone and manipulate them so they're no longer infected, or infectable, no longer infectable by HIV, and those white cells become the whole immune system of that individual, you've got essentially a functional cure," said Levy.
Although the researchers this a "productive area to study," they warned people not to get too excited just yet, because it is not something that can be generalized.
"You don't want to go out and get a bone marrow transplant because transplants themselves carry a real risk of mortality," said Dr. Paul Volberding, another researcher at UCSF.
Volberding added, "one element of his treatment, and we don’t know which, apparently allowed the virus to be purged from his body."

Coffee 'cuts prostate cancer risk' US study suggests


Coffee has been linked to a reduced risk of dying from prostate cancer in a study of nearly 50,000 US men.
Those who drank six or more cups a day were found to be 20% less likely to develop any form of the disease - which is the most common cancer in men.

They were also 60% less likely to develop an aggressive form which can spread to other parts of the body.
But charities say the evidence, reported in the Journal of the National Cancer Institute, is still unclear.
They do not recommend that men take up coffee drinking in the hope of preventing prostate cancer.
Unknown compounds
The study looked at about 48,000 men in the US who work as health professionals.
Every four years between 1986 and 2006, they were asked to report their average daily intake of coffee.
During this 20-year period, 5,035 of the men were diagnosed with prostate cancer, including 642 fatal cases.

Prostate cancer
Each year about 37,000 men are diagnosed with prostate cancer in the UK
Some 10,000 die from the disease
Symptoms include problems passing urine but they may be mild or non-existent

No difference was seen between caffeinated and decaffeinated coffee, suggesting caffeine itself was not the cause.
But even relatively small amounts of coffee - one to three cups per day - were found to lower the risk of lethal prostate cancer by 30%.
The researchers think there may be unknown compounds in coffee that protect against the disease.
Lead researcher Dr Kathryn Wilson, from the Harvard School of Public Health in Boston, said: "At present we lack an understanding of risk factors that can be changed or controlled to lower the risk of lethal prostate cancer.
"If our findings are validated, coffee could represent one modifiable factor that may lower the risk of developing the most harmful form of prostate cancer."
Commenting on the study, Dr Helen Rippon of The Prostate Cancer Charity, said other studies had not shown the link and the research evidence was still unclear.
She added: "Although this study is a welcome addition to our knowledge, it is far from definitive and we would not recommend men who are not already habitual coffee drinkers to become so in the hope of preventing prostate cancer.

The data
Previous studies have shown no clear link between coffee and prostate cancer risk
Men who drank six or more cups of coffee per day had a slightly lower risk of any form of prostate cancer and a substantially lower risk of lethal prostate cancer compared with non-coffee drinkers, according to the researchers
Both caff and decaff were associated with similar risks

"Heavy caffeine intake is associated with other health problems and men with benign prostate problems might well make urinary symptoms worse."
Yinka Ebo, senior health information officer at Cancer Research UK, said: "There's no need for men to start drinking gallons of coffee in an attempt to lower their prostate cancer risk.
"A number of other studies looking at coffee and prostate cancer have found that drinking coffee does not affect the risk of the disease, and this study only found a lower risk of advanced prostate cancer in men who drank more than six cups a day.
"We would need to see these results repeated in other large studies before we can be sure whether coffee consumption affects the risk of prostate cancer."

Is it Skin Cancer? 38 Photos that could Save your Life

Skin cancer is the most common form of cancer, with more than 3.5 million cases affecting more than two million people each year, according to the Skin Cancer Foundation. Early detection and treatment are key, which is why it's vital to pay attention to moles and other marks on your skin (and to see a dermatologist once a year for a skin exam). 

There are three main kinds of skin cancer: Basal cell carcinoma, squamous cell carcinoma, and melanoma, the most lethal form (shown at left). In addition, there are "precancers" called actinic keratoses, along with iffy moles (dysplastic nevi) that could be worrisome. Keep clicking as Dr. Michele Green, a skin cancer expert in New York City, walks us through photos showing the things you should be looking for. The images are graphic, but looking at them just might save your life, or that of someone you love.
Here's a hand with several actinic keratoses - all those red, scaly patches. These back-of-the-hand lesions are common in older golfers and others who spend a lot of time outdoors. Without treatment, actinic keratoses can turn into a form of cancer known as squamous cell carcinoma.

Sometimes it's hard to tell one kind of skin cancer (or precancerous lesion) from another. But this is a classic actinic keratosis - flat, pink and scaly. Yes, you might be able to pick this crusty lesion off with your fingers. But it would grow back. The right thing to do is see a dermatologist and have it removed. 

This raised, scaly patch is an actinic keratosis. It's been marked with ink - in preparation for its removal
.
The red patch on the ear might not look like much, but it's actually an actinic keratosis. These lesions typically feel rough and sometimes bleed. Actinic keratoses tend to occur on areas of skin that get a lot of sun exposure, including the ears, face, scalp, as well as the backs of the hands and the neck.

The ears are another spot where actinic keratoses like these are apt to show up.


This could be an actinic keratosis or squamous cell carcinoma. In general, the prognosis is good for people with squamous cell carcinoma. But a squamous cell carcinoma that develops on the lips or another mucous membrane is more likely to spread (metastasize) - and in rare instances metastatic squamous cell carcinoma proves deadly.

Dr. Green says these white, crusty actinic keratoses look a bit unusual. But like all actinic keratoses, they can turn cancerous. 

This is a classic basal cell carcinoma - the least dangerous form of skin cancer. Note the red color and the almost pearlescent look. These cancers seldom metastasize but can grow larger - and so should be removed. To minimize scarring and disfigurement, a basal cell carcinoma on the face should generally be taken off with a specialized form of surgery called Mohs. Elsewhere on the body, the lesions are often simply burned off.

This basal cell carcinoma has turned into a bloody, oozy mess. Be suspicious of any lesion that bleeds and doesn't heal, Dr. Green says. 

Another basal cell carcinoma - note the pearlescent look. For lesions like this, it's generally best to use Mohs surgery to minimizes scarring and prevent disfigurement. Mohs can usually be performed on an outpatient basis.

Some basal cell carcinomas, like this one, have a raised border.

This basal cell carcinoma of the eyelid is another candidate for Mohs surgery. Skin cancers are common on the face because it gets so much sun exposure over the years. 

Here's a basal cell carcinoma that looks like a scar. Atypical lesions like these can be tricky to diagnose. When she sees a lesion like this, Dr. Green says she typically asks the patient if it's the aftermath of some wound. If not, odds are it's got to come off.

Dermatologists take a close look at pigmented lesions like this one because in rare instances they turn out to be melanoma - the most dangerous kind of skin cancer. But the raised lesion shown here is actually a basal cell carcinoma.

This isn't skin cancer but a dysplastic nevus (mole). Lesions that resemble this dysplatic (the word means the cells look irregular under the microscope) lesion are generally benign. But if you have a lot of them, you may be more likely to develop skin cancer.

Another dysplastic nevus. Note the irregular border and the different shades of color. Those can be signs of melanoma - but not in this case.

Asymmetry is another worrisome sign - that is, when one half of the lesion doesn't look like the other. This happens to be a dysplastic nevus, but asymmetry is also a hallmark of melanoma.


This flat, speckled lesion is a dysplastic nevus.

This close-up shot shows another dysplastic nevus, though the dark color is more typical of a melatoma. "This would scare me," says Dr. Green.

Here is the most worrisome kind of skin cancer: Melanoma. Note the color - it's dark, almost black. The irregular, scalloped border seen in this lesion is another hallmark of melanoma. Over time, melanomas grow and thicken. The thicker the lesion, the worse the prognosis. This one should have been removed long ago.
 
This melanoma has the very dark coloration and the varied (variegated) color. In addition, it's highly asymmetrical. 

Here's a black-and-blue nail, right? Not hardly. It's a melanoma of the nailbed, and lesions like this can be deadly.

This is a very large melanoma on the scalp. It takes awhile for a melanoma to grow this big. For some reason, people sometimes put off going to the doctor even when they suspect they have a problem. In other cases, melanomas are allowed to grow big because they develop on a hard-to-see part of the body.

Melanoma of the face is very common.

This melanoma is fairly advanced - as evidenced by the raised portion. As melanomas grow and thicken, they become harder to treat successfully.


Though much more common in fair-skinned people, skin cancer affects blacks and other racial/ethnic groups too. Here's a melanoma on dark skin.

The pink area next to this melanoma on dark skin may be the result of what Dr. Green calls "regression" - the body has fought back at the lesion, shrinking it a bit. But the body can't cope with a lesion like this. It needs to come off. Yesterday.

This blackish lesion is a melanoma. But melanomas can also look reddish, or even bluish.

This melanoma has been growing for years. Lesions this extensive generally cannot be successfully treated - which is why early removal is so essential.

Here's a bluish-black melanoma. Sometimes melanomas start out as one color and slowly change.

Melanomas on the foot are rare but sometimes deadly - because people may mistake them for warts, delaying treatment by a doctor.


A melanoma this thick is almost certain to prove lethal.

This nodular lesion is a squamous cell carcinoma. These lesions are seldom fatal but can be disfiguring.


Here's a squamous cell carcinoma of the nail.


Squamous cell carcinoma on the back of the hand.


Just a scab? No, this is a squamous cell carcinoma. Because skin cancers often extend deeper into tissue that is readily apparent, the surgery required to remove this lesion is likely to be very extensive - and potentially disfiguring. Better to have it removed before it gets so big.

Removal of a squmous cell carcinoma on the nose, like the one shown here, is another that could prove disfiguring.
