University of Stuttgart researchers used 3D printing to fabricate a tiny three-lens camera that fits on the end of an optical fiber no wider than two human hairs. Eventually, the technology could lead to a new kind of very thin endoscope for looking inside the human body. According to the researchers, the camera delivered "high optical performances and tremendous compactness." From Phys.org:
(The camera) can focus on images from a distance of 3.0 mm, and relay them over the length of a 1.7-metre (5.6-foot) optical fibre to which it is attached.
The "imaging system" fits comfortably inside a standard syringe needle, said the team, allowing for delivery into a human organ, or even the brain.
"Endoscopic applications will allow for non-invasive and non-destructive examination of small objects in the medical as well as the industrial sector," they wrote (in their scientific paper).
Below, the lens (blue) was fabricated directly on the optical fiber (red). The fiber and camera are emerging from a hollow, 27 gauge syringe needle:

Many of us wear fitness trackers to motivate ourselves to be more active. But after a 42-year-old man in New Jersey had a seizure at work, some very smart emergency room doctors used data they saw on his Fitbit Charge HR to decide on the best way to treat him. They decided to reset his heart rate with electrical cardioversion. His Fitbit may have saved his life.

For six months, 5-year-old Khloe Russell was battling what seemed to be a nasty sinus infection. Unfortunately, no antibiotics seemed to help. Last weekend, Khloe's uncle said, "Your nose, it's disgusting. Blow your nose, blow your nose.'" She did, and a blackened, disintegrating safety pin emerged. Khloe feels much better now. From UPI:

"She found a safety pin and being a kid wanted to stick it up there to see how far it would go and thought she dropped it not realizing it had lodged itself in her nose. We went to the same doctor and to urgent cares contracted through our doctors when there wasn't an available appointment. All the doctors looked up her nose but didn't see anything. My daughter didn't mention anything because she didn't realize it had gone into her nose," Powell wrote in the comments to this UPI story.
Powell also told UPI that she's getting "some of the most horrendous hate mail in regards to my parenting skills. I hope people can understand that this can happen to their children and that it doesn't make their children stupid for doing it or not saying anything after."

If you stood next to Sankey Flynn (1918-2001) of Greensboro, North Carolina, you might have thought he had a wristwatch in his head. An audible tick-tock sound could be heard coming from Flynn's ears about twice a second.
According to physicians, the noise came from the "spasmodic contraction of muscles in the roof of his mouth. This causes the eustachian tube, leading from the throat to the ears, to open and shut making the peculiar noise."

In 2001, the roof of a flaming building fell on volunteer firefighter Patrick Hardison, burning his firefighting mask onto his head. As a result, Hardison, now 41, has spent more than a decade without a face. Now, Hardison has the face of David Rodebaugh, a 26-year-old who died in a bicycling accident and donated much of his body for transplant. Surgeon Eduardo Rodriguez and a team at the New York University Langone Medical Center performed the facial transplant, "the most extensive" in history according to the hospital.
Hardison also received a new scalp, ears, ear canals, chin and cheek bones, and Rodebaugh's nose. Previously unable to close his eyes totally, he now has eyelids and also muscles for blinking.
New York University paid for the transplant, totaling $850,000 to one million dollars.

Andrew Wardle suffers from a rare medical condition that prevented him from developing a penis. The 40-year-old man claims that he has been intimate with more than 100 women and most of them never knew he was missing a member.
“I knew my way around a woman’s body, I knew my way around their mind,” Wardle says. “I was very confident in bed of what I could do to them so they wouldn’t come near me and they were finished and I was fine.”
And when that didn't work, he told his partners not to bother because recreational drugs, or kidney disease, made it impossible for him to get an erection at the time.
Wardle is currently undergoing procedures to have a penis constructed from muscle tissue. His story is the subject of a new TV documentary.

"Based on our data, it seems very unlikely that sexual activity is a relevant trigger of heart attack," said Ulm University medical researcher Dr. Dietrich Rothenbache about a new study. From UPI
In relation to their heart attacks, only 0.7 percent of participants they'd had sex within an hour before their heart attack and more than 78 percent of participants said they hadn't had sex in at least 24 hours before having the heart attack. Based on this, and a total of 100 adverse cardiovascular events among the participants in 10 years of following up with them, researchers said sexual activity does not appear to be a risk factor for heart attack.

A man who was anesthetized for a colonoscopy in Reston, Virginia was surprised to hear a recording on his smartphone of the anesthesiologist and others on the medical team acting like total assholes and mocking him while he was unconscious. According to the Washington Post, he had hit record before going under "to capture the instructions his doctor would give him after the procedure." In the resulting lawsuit, the jury awarded the fellow $100,000 for defamation, $200,000 for medical malpractice, and $200,000 in punitive damages. From the Washington Post:

“After five minutes of talking to you in pre-op,” the anesthesiologist (Tiffany M. Ingham, 42) told the sedated patient, “I wanted to punch you in the face and man you up a little bit,” she was recorded saying.
When a medical assistant noted the man had a rash (on his penis, which he previously mentioned to the Ingham), the anesthesiologist warned her not to touch it, saying she might get “some syphilis on your arm or something,” then added, “It’s probably tuberculosis in the penis, so you’ll be all right.”
When the assistant noted that the man reported getting queasy when watching a needle placed in his arm, the anesthesiologist remarked on the recording, “Well, why are you looking then, retard?”
...The discussion soon turned to the rash on the man’s penis, followed by the comments implying that the man had syphilis or tuberculosis. The doctors then discussed “misleading and avoiding” the man after he awoke, and Shah reportedly told an assistant to convince the man that he had spoken with Shah and “you just don’t remember it.” Ingham suggested Shah receive an urgent “fake page” and said, “I’ve done the fake page before,” the complaint states.
The Australian Red Cross Blood Service is testing a technology to project a vein map on the arms of blood donors during the phlebotomy.
"Vein visualisation technology uses near infrared technology to project an image of the vein onto the skin," says Dr. Dan Waller, a senior researcher with the organization. "Veins have a lot of deoxygenated haemoglobin that absorbs near infrared light and the device is able to use this information to project the image. The machines have settings to manage individual differences.

More than 100 Americans die each day from prescription drug overdoses, mostly painkillers. That's more daily deaths than from car accidents, gunshot wounds, or suicides.
In California, two county District Attorneys are suing five of the biggest drug companies in the world, and the lawsuits include the same kind of arguments once used against big tobacco industry, demanding "public protection."
Warren Olney's "To the Point" radio show has a segment on the topic today:
The companies are accused of a "campaign of deception" to persuade doctors that narcotic painkillers are safer than they really are. But the narcotic painkillers involved have been approved by the FDA. Is a government agency helping create a "population of addicts?" What's the role of physicians who write the prescriptions? Are they ill-informed, poorly trained or trying to make money?
