(Yale University) Before infecting humans, tick-borne bacteria or viruses first have to get past a tick’s defenses to colonize it. How this occurs is not well understood. To investigate, Yale researchers studied a model of the second-most-common tick-borne infection in the United States, human granulocytic anaplasmosis, which can cause headaches, muscle pain, and even death.

Conclusions
This study supports existing evidence that HeartMath techniques are effective in managing stress and increasing resiliency. These techniques are also valuable tools for health care providers to use with patients and their families in the management of symptoms such as pain, anxiety, and sleeplessness related to hospitalization and illness.

Hi! I’m a PGY1 in a Prelim-IM year, heading to my PM&R Advanced program this coming summer 2020. I’ve read through all of the old threads that discuss pain vs. sports vs. sports/spine vs. interventional spine fellowships. Ultimately, from what I gather, the majority of opinions are that if you’re going to do a fellowship, most likely do something that will give you the board certification at the end because it will open the most doors and keep you pretty safe, legally. Interventional Spine…

AbstractHuman granulocytic anaplasmosis (HGA) is a tickborne rickettsial disease caused by the bacteriumAnaplasma phagocytophilum. Reported cases have increased with the highest incidence in the Northeast. To our knowledge, this is the first report of anaplasmosis associated with an inflammatory arthritis. A 64-year-old man, with a history of Crohn ’s disease controlled on budesonide, presented to the emergency room in August 2017 with a week history of headache, sore throat, fever, myalgias, rash, and joint pain. There was no clinical evidence of active Crohn’s disease. He lives in Nassau County and participat…

For most of us, springtime marks the return of life to a dreary landscape, bringing birdsong, trees in bud, and daffodils in bloom. But if you work for the Centers for Disease Control and Prevention (CDC), the coming of spring means the return of nasty diseases spread by ticks and mosquitoes.
The killjoys at CDC celebrated the end of winter with a bummer of a paper showing that infections spread by ticks doubled in the United States from 2004 to 2016. (Tick populations have exploded in recent decades, perhaps due to climate change and loss of biodiversity.)

“Doesn’t it typically happen during the summer?” asked a worried lady that had walked into my clinic in November with a growing circular rash on her wrist. She was referring, of course, to Lyme disease, that scourge of outdoor enthusiasts. While the peak season for Lyme disease is indeed summer, the ticks that transmit it are active March through December. And, while this may be off-season for the ticks, it is a good time to catch up on how to stay safe in the not-so-distant spring.
What is Lyme disease, and how do you treat it?
Lyme disease is caused by a bacterium called Borrelia burgdorferi which is sp…
