An unexpected discovery out of Frenchay Hospital in Bristol, UK showed that deep brain stimulation (DBS) can lower blood pressure, even in cases in which drugs are unsuccessful.
The discovery reportedly occurred when a 55-year-old patient received a deep brain stimulator to treat his pain from central pain syndrome that developed after a stroke. At the time of the stroke, the patient was diagnosed with high blood pressure, which could not be controlled despite taking four different drugs. The deep brain stimulator was largely unsuccessful at controlling the patient’s pain, but amazingly it decreased his blood pressure enough that he could stop taking all four medications.
Researchers confirmed the effects of the deep brain stimulator by turning it on and off over a three-year period, which showed an average of a 32/12 mmHg decrease in blood pressure when the stimulator was turned on and an 18/5 mmHg increase when the device was turned off.
This breakthrough could lead to a new form of treatment for those whose hypertension cannot be controlled by drugs.
Press release from the American Academy of Neurology: Deep Brain Stimulation May Help Hard-to-Control High Blood Pressure…
Abstract in Neurology: Deep brain stimulation relieves refractory hypertension

Antibodies can fight viruses from within infected cells, reported researchers who now believe that treatments could be applied to viral diseases like the common cold, “winter vomiting,” and gastroenteritis.
Previously, scientists thought that antibodies could only reduce infection by attacking viruses outside cells and by blocking their entry into cells. Once inside the cell, the body’s only defense was to destroy the cell. But protection mediated by antibodies doesn’t end at the cell membrane. It continues inside the cell to provide a last line of defense against infection.
Researchers at the U.K.’s Medical Research Council’s Laboratory of Molecular Biology showed that cells possess a cytosolic IgG receptor, tripartite motif-containing 21 (TRIM21), which binds to antibodies with a higher affinity than any other IgG receptor in the human body. Antibodies remain attached when viruses enter healthy cells. Read more »

I’ve watched the pendulum swing back and forth on the wisdom of mom sharing her bed with a baby. The American Pediatric Society has come out against the practice, because of a higher incidence of sudden infant death. But nearly half of all British moms sleep with their baby at times, and one-fifth share a bed regularly during the first year.
According to a British study published in [the October 2010 issue of] Pediatrics, the value of breastfeeding should be considered before advising mothers not to share beds with their infants. The results showed that mothers who shared a bed with their newborns were better educated and of a higher socioeconomic status, and that those whose children routinely slept in their beds during the first 15 months of life reported a significantly greater incidence of breastfeeding.
“Both cross-sectional epidemiological and sleep laboratory studies showed close links between the frequency and duration of breastfeeding and the practice of bed sharing,” writes Peter Blair, PhD, Community-Based Medicine and Social Medicine, University of Bristol, United Kingdom, the author of the study.

Although it happened a few weeks ago, I only recently learned of the “retirement” of the blog called “Medic999” by EMS social media superstar Mark Glencourse who works in the United Kingdom. I only learned of Mark and his blog (which was recognized as the 2009 Fire/EMS Blog of the Year) in the past few months in association with the hugely popular Chronicles of EMS project (see the first episode on video here).
In stating why he was stopping his blog, unfortunately, I find similar thoughts being shared by the medical colleagues I know about why people either stop blogging or don’t ever start in the first place:
I find it a shame that the reason for this blog ending is the general lack of understanding of blogging and social media. I feel that I have promoted best practice, shared my passion for the job that I do, and hopefully have shown all readers what it is that makes EMS and those that devote their lives to it so special.
However, there still remains a general unease about social media and blogging in the health service. Read more »
