The 'Tree Man' of Bangladesh Gets His Hands Back

You might remember the story of Abul Bajandar, the Bangladeshi man who gained a measure of internet notoriety last year for his curious medical affliction. Since age 10, Bajandar has suffered from epidermodysplasia verruciformis, an ultra-rare skin disease characterized by extreme sensitivity to the human papillomavirus (HPV), which prompted bark-like warts to practically swallow his hands.

Homeopathy and natural cures didn’t work; neither did trying to remove them himself. They’d only grow back stronger and larger.

Fortunately, Bajandar's story looks to have a happy ending. According to The Washington Post, physicians at Dhaka Medical College Hospital have spent the past year performing 16 separate surgeries in an effort to give Bajandar his hands back. They’ve succeeded.

Although he’s still recovering, Bajandar now has use of his hands, making him the first person to potentially be cured of EV. (While there is currently no long-term treatment to prevent the growths from returning, surgical excision seems to be effective.) Eating, writing, holding his daughter, and other fine motor skills are now possible. Previously, Bajandar was in so much pain that he was unable to work or care for his basic personal needs.

Doctors say Bajandar still has a few procedures left to go, mainly to improve his cosmetic appearance. While it’s possible the warts may grow back at some point, Bajandar appears to no longer have a need for his “tree man” label.

New Technique Can Spot a Heart Attack in the Making Long Before It Happens

Cardiology experts have developed a noninvasive way of measuring the fat around a person's blood vessels, which could help determine their risk for dangerous cardiac events. The researchers described their technique today in the journal Science Translational Medicine.

Heart attacks are incredibly common, affecting around 750,000 Americans every year. Heart disease is the number one cause of mortality in the U.S., responsible for one out of every four deaths. There are many reasons for this. Among them is the difficulty of identifying at-risk patients before it's too late.

Cardiologists' current method of choice uses a metric called coronary calcification score (CCS) to measure the hardening of a patient's arteries. CCS is a reliable way to predict future heart problems, paper co-author Charalambos Antoniades said in a statement, but it has its limitations.

"When coronary calcification is detected," he said, "it is already too late, as the calcification is not reversible."

And so, rather than measuring calcification, many researchers have begun looking for a way to measure blood vessel inflammation, which is usually a pretty good—and early—predictor of heart disease.

The inflammation itself can be hard to see without entering a patient's body. But recent studies have shown that it rarely travels alone: Blood vessels that are inflamed are also often wrapped in larger fat cells than healthy vessels. 

With this link in mind, Antoniades and his colleagues decided to try measuring the fat cells instead. They reviewed computed tomography scans from 453 patients about to undergo heart surgery, and used these data to create what they call the fat attenuation index (FAI). The higher a patient's FAI, the more inflammation they had, and the more advanced or severe their heart disease. 

The researchers then compared the FAI of 40 additional patients with the results of invasive scans of the inflammation in their hearts. Sure enough, each patient's FAI matched the swelling onscreen.

There are many benefits to using FAI, the authors say. Not only is it noninvasive and accurate, but it can be used in tandem with CCS and other methods for an even more complete picture. The next step will be validating the test's safety and accuracy in clinical trials.

FAI scans "could help direct these new types of treatments to the appropriate subgroups of patients at greatest risk," Antoniades says, "reducing costs and targeting more powerful drugs to the patients who will benefit most."

Don't Panic About the Plague

If reports of measles and whooping cough making a reappearance aren't alarming enough, the news that three people in New Mexico have contracted plague this year might have you on edge. But these aren't the only recent cases of plague in the state—the disease appeared in both 2016 and 2015, causing one death—or even in the U.S.

In 2015, a child contracted the plague in Yosemite National Park, and so did a tourist from Georgia; park officials closed a campground where they discovered two dead squirrels infected with the disease. That same year in Colorado, a pitbull infected four humans with pneumonic plague before being put down, and two other Colorado residents died from plague, including a 16-year-old boy.

It all seems very scary, but don't go sealing yourself in protective gear yet. There's less to fear about plague than you may think. While the public is prone to panic that a medieval illness, which wiped out a quarter of Europe in the Middle Ages during the Black Death, has suddenly arisen from obscurity, the truth is: Plague never left.

Though we haven't seen a widespread epidemic of plague since the early 20th century, thanks to advances in sanitation and medicine, and there hasn't been a human-to-human case of transmission in America since 1924, an average of seven new cases are reported every year in the U.S. From 2010 to 2015, there were 3248 cases, including 584 deaths, reported worldwide, according to the World Health Organization.

Yersinia pestis, the flea-borne bacteria that's most often responsible for plague, infects rodents; humans are “incidental hosts,” who can acquire the infection if bitten by an infected flea or rodent. Compared to the 14th century, when the Black Death spread wildly, or the late 19th century, when 10 million people died of the disease after it traveled from Hong Kong to port cities worldwide, most people today live in more sanitary conditions and have less frequent contact with the rodents most likely to carry the infected fleas. Today, 95 percent of plague cases originate in parts of sub-Saharan Africa and Madagascar.

The most common of the three strains of plague is the notorious bubonic plague, which causes painful swollen lymph nodes (also called buboes) and was responsible for Europe's Black Death—so named because internal hemorrhages caused by the infection make the skin appear black. But the pitbull that infected four Colorado residents carried the rarer respiratory strain of pneumonic plague, which is contagious when the infected person coughs up infected particulates. There is also septicemic plague, the most lethal form, which infects the blood, and most often occurs when plague virus has gone undetected and is allowed to spread.

In the U.S., you're generally only at risk of contracting plague in late spring to early fall if you've been in a rural or semi-rural area of the West, especially New Mexico, Arizona, or Colorado, and have had contact with fleas or rodents including ground squirrels, chipmunks, prairie dogs, or rats. And even then, the risk is low.

Only the pneumatic version of plague is contagious from human to human (though untreated bubonic plague can become pneumonic), but you have to be coughed upon, or receive fluid from an infected person upon an open wound or directly into your mouth or nose.

Plague symptoms mimic any flu—fever, chills, headache, difficulty breathing or coughing—but people have been known to cough up blood with the pneumonic variety. If you've been in a rural area, or camping, and come down with these symptoms two to three days later, it's best to go to a hospital.

Now for some good news: While untreated plague is quite deadly, people with plague who are treated with antibiotics within 24 hours of infection have strong recovery rates.

So while it's good to be aware and take precautions, the chances of another plague pandemic remain slim.
