Hikers often brush up against injurious plants, such as poison oak or thorny shrubs. One particularly vexing plant is the “ubiquitous weed, Urtica dioica,” commonly known as stinging nettles. As described in an article entitled “Mechanism of Action of Stinging Nettles” (Wilderness & Environmental Medicine:22,136-139,2011) by Alexander Cummings and Michael Olsen, direct contact exposure to the weed causes immediate stinging and burning sensation on the skin. The authors exposed mouse skin to the plants and looked at this skin using an electron microscope. They found smooth nettle spicules that had pierced the skin surface, a few of which retained their bases, which appeared empty of liquid contents. The authors concluded that the mechanism of action of stinging nettles skin reaction was both biochemical and mechanical, likely caused by impalement of spicules into the skin.
The spicules are present as small “hairs” that are found on the stem and undersides of the leaves of the plant. Even light touch against the plant can cause a reaction, which is often characterized as Read more »

A 47-year-old Chicago man died after trying to remove his own pacemaker. He’s not the first to try self-surgery, as it turns out.
The Chicago Tribune described this most recent attempt at self-surgery:
“Chicago Fire Department paramedics were called after the man told a worker in the home that he was experiencing chest pains and asked them to call an ambulance.
“The man returned to his room, where he remained until paramedics arrived, police said. When they did, he complained to them about chest pains and was taken to the ambulance where he fell unconscious, police said.
“As paramedics were trying to revive him, they discovered Read more »

Reader’s Digest has published an article, “50 Secrets Nurses Won’t Tell You“. The link will take you to the article itself, and Sandy Summers has written a review of the article at The Truth About Nursing.
There are some interesting “secrets” here – and you’ll recognize a few of the names!
Gina from Code Blog is in there, and so is Jo from Head Nurse!

I’ll be the first person to tell you that I am not a perfect person, and not a perfect nurse, but two of these “secrets” really ticked me off.
Royally.
The first one: Read more »

I was hiking in the woods recently with a group of women friends when something caught my attention. It wasn’t an interesting bird or plant, but the surprising number of “pit stops” my friends needed to make.
Their frequent detours into the bushes struck me because I had just finished working on Better Bladder and Bowel Control, the latest Special Health Report from Harvard Medical School. According to the report, incontinence is the unintended loss of urine or feces that is significant enough to make it difficult to do ordinary activities without frequent trips to the restroom. In the United States, about 32 million men and women have some degree of incontinence. For women, incontinence is a common but rarely discussed result of childbirth and aging—that could explain the pit stops of my hiking friends, who were all mid-life mothers. For men, incontinence is most often a side effect of treatment for prostate disorders.
Many things can go wrong with the complex system that allows us to control urination. Read more »

I always loved to type. It started in high school with typing class. We were told that typing was critical for college term papers. I liked it so much that I took advanced typing. It was myself and 12 girls with Farrah Fawcett hair. Heaven.
Fast forward to 2011. My interface with the medical record is my fingers. Most of my communication flows through my hands. I complete the core of my documentation in the exam room. Fast documentation of information at the outset of an encounter allows for meaningful, eye-to-eye dialog during the latter part of the visit.
Those who can’t type have a different experience with their EHR. Sure there’s voice recognition but when pressed they wish they could make a sentence instantly flow onto the screen. Two colleagues this week, one from Barbados and another from the UK, Read more »
