Beautifully presented, Dr Campbell. I thoroughly enjoy these short lectures because they expose me not only to medical situations but also to associated treatments and various drug names.
@@Campbellteaching they will love this. Both are on school holidays.. but one has to attend compulsory exams this week... today Chemistry, tomorrow Physics and Biology.
Great explanation! Thank you! I have one question: does it means that Anaphylaxis will occurs when SECOND exposure to allergen was happened? For example: vaccination - is the first vaccination (even body is allergic to this vaccine or compounds) will NEVER cause anaphylaxis? Only second vaccination can cause anaphylaxis? Why I'm asking because I have some connection to Pharmacovigilance and case assessment and often we have the cases when after first vaccination anaphylaxis is reported (swelling, vascular disorders etc). Thank you in advance for your reply!
A very brief and detailed insight into anaphylactic reaction...I just learned anaphylaxis in emergency and this video had been very helpful in understanding the importance of adrenaline during these reactions.
Thank you for this video. I appreciate your time. I don’t understand one thing. So these mast cells are in our body to defend against antigens. But here we see that chemicals inside the mast cells cause people to die. So in which scenario these mast cells can do their job successfully without a damage to the body?
Excellent! I'm 61 and 10 years post menopausal. At 53 I went into anaphylactic shock for the first time to almonds, which I had eaten for years. Then 3 years later it happened again to peanuts, which I'd eaten for years. Then I had mast cell activation disorder for about 8 years until I ramped up my diet and transitioned to a whole food plant based lifestyle. I no longer have any type of mast cell disorder, which I'm grateful for...because for a long time by body reacted to anything with the smallest amount of histamine. I still cannot tolerate any type of nuts (never again almonds or peanuts!). I have some bronchial reactions even when trying to introduce small gradual amounts as in desensitizing and I have rashes to trace amounts of nut oils in lotions. So I have forever eliminated them. Can you explain the sudden "change"?
What about type 2 to 4 hypersensitivity, I honestly like the way you lecture. You always touch every Conner of the things you lecture. Very understanding
I had Anaphylaxis reaction to Meningococcal vaccine long time ago which ended up getting epinephrine injection but I'm really concerned about getting any vaccine ever since. What would be the best procedure if i have to get the Covid-19 vaccines? Any particular test i need to do beforehand? Cheers.
There's no test beforehand. The two vaccines are different, but without knowing what specifically you were allergic to in the Meningococcal vaccine, it is hard to know if it won't happen again. The vaccines are different but may have the same ingredient in that you are allergic to. You will need to speak to your GP.
Hmm, I guess both are true, an antigen is anything recognised as foreign, and in the case of an allergen something is recognised as foreign which should not be recognised as foreign, rather it should be immunologically tolerated. So in allergy an allergen is recognised as an antigen.
Beautifully presented, Dr Campbell.

Absolutely fantastic presentation, good pace, very clear, as a student paramedic it has helped my understanding of Anaphylaxis.
Thank you.
Excellent explanation, very helpful for understanding my child's allergy, thank you very much Dr. Campbell
Reading the comments made me realise that you're appreciated all around the world. Im thankful for your succinct teachings.
Thanks Sheri, the internet and TH-cam are amazing.
Another excellent presentation. Sharing with my girls studying for science exams at college.
Don't be too hard on the girls

@@carolyn3746 well, its all proper science
Thanks Sir for your efforts

wow thank you Dr.john...once again another knowledge impart that really help me with my lecture with poisoning, thank you and GOD bless.

Yes, it's the early adrenaline that makes the difference.
@@Campbellteaching thanks a lot for the update as well..
Type 1 hypersensitivity powerful and sensible wide explanation from my Professor.
Thanks a lot Sir
Sir you're one of the world best tutor I ever seen
Amazing video. Thank you
Anaphylaxis can be a scary time
sure can, worse for our patients though
i've never understood anaphylaxis in this level! thank u so much!!

Awesome, sir! Thanks for the knowledge
Very informative👏👏👏
Yor explenation is very good and I realy benfit from it thank you so much
Thank you Dr. Campbell
Thank you. This is rather helpful.
Can sore throat and skin rashes occur in the first exposure?
Great explanations Thanks so Much
Amazing presentation, thank you sir!
Bravo
Very grateful!!!!!
Very helpful ...thanks man
Thanks
Tnk u sir ji..
Sir we want some lactures on developmental biology
There are some already uploaded on the cardiovascular and respiratory system in children
@@Campbellteaching Gametogenesis, fertilization,and early development...
And morphogenesis and organogenesis in animals
@@biomastryclassroom95 Certainly possible, I will put it on the to do list, it's just getting the time.
@@Campbellteaching okay..
Dear sir ji..
We hope u..
Tnk u so much...🌷🌷
Thank you again 🙂
Had a medic call today that was anaphylaxis
at 3:55 in allergy antigen is recognized as allergen or allergen is recognized as antigen ? thanks
Hmm, I guess both are true, an antigen is anything recognised as foreign, and in the case of an allergen something is recognised as foreign which should not be recognised as foreign, rather it should be immunologically tolerated. So in allergy an allergen is recognised as an antigen.
have you watched the next video in the series?
@@Campbellteaching
not yet, but I will watch that certainly as soon as posible.thanks
thank you for such an informational explanation!
