The strangest medical story ever
|
view preview
This 22-year-old man had a car accident last year and as a result his nose became infected and deformed. Doctors weren’t able to repair it, but decided to take cartilage from one of the young man’s ribs to grown a new nose. The nose, which is temporarily attached to his forehead, has been developing for 9 months and is ready to be transplanted.

Potential treatment for Down's syndrome?
|
view preview
Down syndrome is caused by a triple copy of chromosome 21, which leads to a number of cognitive and physical delays. Now researchers from the Sanford-Burnham Medical Research Institute in La Jolla, California, have found a protein that restores the some of the cognitive and behavioral disorders found in the disease. Mice who were deficient in the SNX27 protein exhibited similar characteristics to mice with Down syndrome—namely, they had fewer glutamate receptors, which are important for learning and memory, the team reported in Nature Medicine on Sunday (March 24). The researchers also showed that in mice with Down syndrome, the protein is blocked by a molecule encoded on chromosome 21, and produced in excess in Down syndrome mice as a re ...

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. ...

C-section on a turtle?
|
view preview
Surgeons performed a C-section on this turtle and saved her life! A turtle named Dabao was a bit lethargic and zookeepers at China’s Chengu City Zoo thought she was sick and sent her for x-rays. The results were surprising: 14 eggs were stuck in the birth canal. To make sure Dabao survived, the surgeons opened the shell with a skull opener, carefully removed the 14 eggs (which were immediately buried in sand to await hatching) and resealed the shell with epoxy resin.

What causes the brown staining of some childrens teeth?
|
view preview
The brownish staining of a child's tooth enamel is due to excessive ingestion of fluoride. Fluoride is a mineral compound that is useful in preventing dental caries. It is thought to work by strengthening the mineral composition of tooth enamel making it more resistant to acid attacks. It may also reduce the acid-producing ability of microorganisms in dental plaque. The water supply may naturally provide fluoride, or it may be added. Mild fluorosis causes white mottling of the teeth; severe cases show brown staining and usually occur in areas where the level of fluoride in the water is many times greater than the recommended level of 0.7 to 1.2 parts per million. ...

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.
