Baby blue eyes
|
view preview
Waardenburg Syndrome is a rare autosomal genetic disorder that has possible bright blue eyes as one of its qualifying criteria, along with possible deafness (common). Actually, the cause of the blue eyes is a form of albinism that may include patches of non-pigmented skin or forehead hair, regardless of ethnicity. There are four types of Waardenburg Syndrome, with a mix of possible characteristics as the determinant. Medical challenges increase with type. The boy in the picture is displaying two major symptoms of type 1; bright blue eyes and dystopia canthorum, a condition where the inner corners of the eyes are set more widely apart, but with normally distanced eyes. ...

Pellagra
|
view preview
In the early 1900s, the disease pellagra was widespread in the United States, especially in southern states. Individuals with pellagra were weak, and they developed diarrhea, a skin rash, and mental confusion. Each year, thousands of Americans died from this dreaded illness. In 1914 the U.S. surgeon general assigned Joseph Goldberger, a physician who worked in a federal government laboratory, to study pellagra. Most medical experts thought pellagra was an infectious disease because it often occurred where people lived in close quarters, such as prisons, orphanages, and mental health institutions. Goldberger knew from his previous research that infectious diseases usually spread through a population by close physical contact. While investiga ...

Insights into the Hippocampus

view preview
When Henry Molaison (now widely known as H.M.) cracked his skull in an accident, he began blacking out and having seizures. In an attempt to cure him, daredevil surgeon, Dr. William Skoville, removed H.M.'s hippocampus. Luckily, the seizures did go away — but so did his long-term memory! Sam Kean walks us through this astonishing medical case, detailing everything H.M. taught us about the brain and memory.

Cancer, could it be just bad luck?
|
view preview
In a paper this week in Science, two scientists at John Hopkins have united biology and mathematics to propose a mathematical formula to explain the genesis of cancer. Take the number of cells in an organ, identify what percentage of them are long-lived stem cells, and determine how many times the stem cells divide. With every division, there’s a risk of a cancer-causing mutation in a daughter cell. Thus, Tomasetti and Vogelstein reasoned, the tissues that host the greatest number of stem cell divisions are those most vulnerable to cancer. When Tomasetti crunched the numbers and compared them with actual cancer statistics, he concluded that this theory explained two-thirds of all cancers. “Using the mathematics of evolution, you can really ...

Brain just can't catch a break

The importance of adequate, non-distracted, deep sleep could not be emphasized enough. Recent research has put the brain yet again under the spotlight, this time only to shed some light on one more reason we should be getting our sleep and why. Make sure to watch the video above. It is hands down, one of the best TED talks I have listened to. As for now, I'mma go make my CSF flush my amyloid betas Nighty, night!

What would happen if you didn't get stitches?

I have a big scar on my leg from when I was a kid. I often wonder what would have happened if we let it heal on its own without using stitches. Here's what happens when you do get stitches: Here's what happens without stitches: And finally, this scenario often leads to contamination. In this case, you'd get this: ...

Parasitologist espouses using parasitic worms for treatment of autoimmune diseases – Dr. Joel Weinstock, at Tufts Medical Center in a commentary piece published in the journal Nature, describes work that he and colleagues have been involved in that focuses on studying the possibility of introducing parasitic worms into the guts of patients suffering from autoimmune diseases such as Crohn's disease. The thinking he says, is that modern hygienic lifestyles may be contributing to such diseases and that reintroducing parasitic worms and perhaps certain bacteria into the gut may restore a natural balance in the gut and relieve patients of such symptoms as chronic diarrhea, bleeding and infections.

Brain defects go a long way
|

This is a human brain without grooves and folds, a condition known as lissencephaly. It belonged to a patient who died in a mental health facility in 1970, and almost a year ago a photographer found the jar containing the brain in a collection at the University of Texas, Austin. People with this rare condition suffer from seizures, muscle spasms, a range of learning difficulties, and usually die before the age of ten. ...
