Continuo a scrivere alcuni post (con materiale preso dal web) dedicati ad argomenti di medicina che mi coinvolgono personalmente in seguito all’interesse che suscitano in me.

The pancreas /ˈpæŋkriəs/ is a glandular organ in the digestive system and endocrine system of vertebrates. In humans, it is located in the abdominal cavity behind the stomach. It is an endocrine gland producing several important hormones, including insulin, glucagon, somatostatin, and pancreatic polypeptide which circulate in the blood. The pancreas is also a digestive organ, secreting pancreatic juice containing digestive enzymes that assist digestion and absorption of nutrients in the small intestine. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.

Hiv Undetectable

Continuo a scrivere alcuni post (con materiale preso dal web) dedicati ad argomenti di medicina che mi coinvolgono personalmente in seguito all’interesse che suscitano in me.

I was thinking about this clip. Well, here are my thoughts.
I don’t accept life in less than perfect health. I strongly claim my right to dispose of my existence, in the (future) event I knew something was wrong with myself.
Having the smallest probability to infect my partner, or being forced to choose who I can love, is not how I would want to be living. In that case, I hope I could use the right to resort to euthanasia.

I’m no doctor, so even if a particular HIV strain with inherently undetectable viral load didn’t exist, I guess it would be possible to keep the viral load to undetectable amounts by administering medication, somehow.

Of course, this is is just hypothetical and theoretical, so don’t get worried. Everything is fine :)

Oliver Sacks’ quote

Around 1970, it was found that there were not only parts of the brain, but particular cells. “Face cells” were discovered around 1970. And now we know that there are hundreds of other sorts of cells, which can be very, very specific. So you may not only have “car” cells, you may have “Aston Martin” cells.  I saw an Aston Martin this morning. I had to bring it in. And now it’s in there somewhere.

Rectal bleeding can refer to any blood that passes from your anus, although rectal bleeding is usually assumed to refer to bleeding from your lower colon or rectum. Your rectum makes up the last few inches of your large intestine.

Rectal bleeding may show up as blood in your stool, on the toilet paper or in the toilet bowl. Blood that results from rectal bleeding can range in color from bright red to dark maroon to a dark, tarry color.

What is Short-Term Memory Loss?

Continuo a scrivere alcuni post (con materiale preso dal web) dedicati ad argomenti di medicina che mi coinvolgono personalmente in seguito all’interesse che suscitano in me.

When a person experiences short-term memory loss, he or she can remember incidents from 20 years ago but is fuzzy on the details of things that happened 20 minutes prior.

There are a number of causes of short-term memory loss, some which are a result of medical conditions and others that are related to injuries or other outside influences.

Chip, Implanted in Brain, Helps Paralyzed Man Regain Control of Hand

Five years ago, a college freshman named Ian Burkhart dived into a wave at a beach off the Outer Banks in North Carolina and, in a freakish accident, broke his neck on the sandy floor, permanently losing the feeling in his hands and legs.

On Wednesday, doctors reported that Mr. Burkhart, 24, had regained control over his right hand and fingers, using technology that transmits his thoughts directly to his hand muscles and bypasses his spinal injury. The doctors’ study, published by the journal Nature, is the first account of limb reanimation, as it is known, in a person with quadriplegia.

Dyslexia

Dyslexia, also known as reading disorder, is characterized by trouble with reading despite normal intelligence.[1] Different people are affected to varying degrees.[2] Problems may include difficulties in spelling words, reading quickly, writing words, “sounding out” words in the head, pronouncing words when reading aloud and understanding what one reads.[2][3] Often these difficulties are first noticed at school.[4] When someone who previously could read loses their ability, it is known as alexia.[2] The difficulties are involuntary and people with this disorder have a normal desire to learn.[2]

The cause of dyslexia is believed to involve both genetic and environmental factors.[4] Some cases run in families.[2] It often occurs in people with attention deficit hyperactivity disorder (ADHD) and is associated with similar difficulties with numbers.[4] It may begin in adulthood as the result of a traumatic brain injury, stroke, or dementia.[1] The underlying mechanisms are problems within the brain‘s language processing.[2] Dyslexia is diagnosed through a series of tests of memory, spelling, vision, and reading skills.[5] Dyslexia is separate from reading difficulties caused by insufficient teaching; or either hearing or vision problems.[4]

Treatment involves adjusting teaching methods to meet the person’s needs.[1] While not curing the underlying problem, it may decrease the degree of symptoms.[6] Treatments targeting vision are not effective.[7] Dyslexia is the most common learning disability,[8] affecting 3–7 % of the population;[4][9] however, up to 20% may have some degree of symptoms.[10] While dyslexia is more often diagnosed in men,[4] it has been suggested that it affects men and women equally.[8] Dyslexia occurs in all areas of the world.[4] Some believe that dyslexia should be best considered as a different way of learning, with both benefits and downsides.[11][12]
