i've been reading about fever on uptodate and man it took me some big time and concentration to understand the articles but your video and the way you explained it was so nice and simple and easy to understand and memorise too! thank you!
2nd yr RN here, So just to clarify, a fever must involve a change of hypothalamic set-point. The pyrogen controlled hypothalamic set-point is what defines what is and what a fever and what is not. Some cancers, heavy metal poisoning or even exercise induced hyperthermia may involve a raised body temperature, without a change in hypothalamic set-point, therefore these conditions would not be a fever or febrile. Can you clarify my understanding?
Hello, can fevers be self limited? Or specific to a body part? I have been feeling that my head is warmer than normal and l havs been having flu symptoms. I took my temp. under my arm 3 times, twice yesterday and once today. All three were under 99° F but then l took it under the tongue today after putting the digital thermometer inside a bag in case it wasn't 100% clean from previous axillary use. It got to 100.1° F although l tried to not exhale because l knew I have been exhaling hot air. I tested at home for Covid concerned about all the mucus l have been coughing and it was negative. My mother did the hand to forehead and agreed it was a fever. She mentioned an infection, but l thought a fever included the whole body temp. Does seriousness of the issue determine how big the fever is, body or specific? 🤔
thanks a lot . I HAVE A QUESTION PLEASE THE FEVER IS AN IMMUNE REACTION HELPS TO DESTROY GERMS BUT GIVEN MEDICATIONS WILL REDUCE IT SO SHOULD WE GIVE THEM ANTI BIOTICS
@@JoaoMartins-yx3ny thanks a lot for the answer, it was very interesting question at that time. anyway fever in did is a physiological reaction of organisms but sometimes it can be dangerous +++ in the pediatric world: it may cause seizures / dehydration / fatigue
It is syntheized as reaction to infection from pathogens or sometimes Trauma. Phospholipase A2 breaks down then Phospholipids from cell membranes to Arachidonic acids. They in turn are catalyzed by cyclo-oxigenase (enzyme) to the Prostaglandines (amongst others PGE2). goes up to anterior part of hypothalamus (mentioned in the video).
yes it it, it's a response of the body against infections....by raising the body temperature the hypothalamus makes the body uninhabitable for the microorganisms.

As a layman who didn’t finish high school, this was really interesting and you made it very easy to understand. Fascinating and thanks for the upload!
james2488 thank you! What a wonderful compliment! 😊
Thank you so much. Our professor managed to make physiology the most boring module in medicine so you're my new physiology professor now :)

Please make more videos you have a real talent
Excellent job! Thank you for making this video. It's simple and comprehensive.

What about advil
I'm watching this as I'm having a fever

sometimes fever can be hard to contain and self destructive, so anti biotics help control the normal physiological mechanism

But where does the pge2 come from?
It is syntheized as reaction to infection from pathogens or sometimes Trauma.
Phospholipase A2 breaks down then Phospholipids from cell membranes to Arachidonic acids. They in turn are catalyzed by
cyclo-oxigenase (enzyme) to the Prostaglandines (amongst others PGE2). goes up to anterior part of hypothalamus (mentioned in the video).
This was super helpful, thanks mate.

Hello there!
Is fever a positive feedback?
yes it it, it's a response of the body against infections....by raising the body temperature the hypothalamus makes the body uninhabitable for the microorganisms.
2:22 So if temperature through a catheter is more accurate, why not make catheters with an embedded temperature reading device so that any patient who already has a catheter inserted can easily have an accurate temperature reading?
