helpful for non foot ball fans like few of us; I watch England foot ball so "No.18 is the referee who don't you out of the foot ball court during the game because no body can give him red card unless a LADA taxi come and give them lift! so number 18, refree BooooM, can afford LADA taxi "
You know for the visualization of Chediak-Higashi it also works if you make him a The White Knight Chediak-Higashi since it also causes partial albinism.
As an added bonus, Wiskott *ALL*-DRINK syndrome shows it affects both T and B cell lines (IgG) therefore causing the pt to get all infections (viral, bacterial and fungal). Great video, as always.
"fungus went up your ass? throw some hydrogen peroxide at it" ---I don't think I've ever laughed that hard and not to mention I will never forget the enzyme again. ty ur videos are AMAZING.
Thanks for the mnemonics! I have one for LAD that helped me remember - "LADs must be 18 to Integrate" LAD - Leukocyte Adhesion Deficiency Must be 18 - CD18 Integrate - CD18 is an "integrin" that is necessary for migration
Hey! Took step 1 today i get home and see this. I got 2 questions on CGD, one Bruton's and leukocyte adhesion which was baby who umbilicus doesn't fall off. Quick tip: study PARASITES!!!! who said they were low yield. Btw great videos guys... keep it up
No joke just finished this video and on a random UWorld block, first question is on CGD. Had to pause the block to laugh for a good 2 minutes. Great video!
A in WATER could also stand for "actin" because the WAS gene mutation leads to leukocytes/platelets being unable to reorganize their actin cytoskeleton --> ineffective APC function. Also thinking of it as Wisxott rather than Wiskott as it is X-linked recessive!
Hi, your videos are amazing + life saver!! For future video topics, could you possibly do them on these: 1) antibiotics overview = when to use which + high yield side effects 2) cardiovascular drugs 3) Dermatology stuff (eg papules/macules etc...) = relevant for step 1 4) GI patho
Correct me if Im wrong, as for the CGD The nitro blue test Positive = patient have super oxide therefore patient is free from the disease Negative = patient has the disease as the nitroblue remains blue! I think you may have confused us on the positive and negative. Patient has CGD if the test is NEGATIVE not as mentioned in ur video. Do check wiki or correct me if I'm wrong
Not quite! NBT is a colorless dye by itself. He clarifies this in the errata (pinned as the top comment). DirtyUSMLE wrote that the NBT is backwards as per the vid! Here's how it should be: Normal (positive) = turns from clear to BLUE (neutrophils can turn the dye blue because NADPH oxidase is present). In Chronic Granulomatous disease, it's Abnormal (Negative) = No color (indicates that there's No NADPH oxidase). No color = No NADPH Oxidase present Hope this helps!
Actually, in CGD the Nitroblue tetrazolium, if it’s positive meaning it turn blue the patient doesn’t have the disease. In the other hand, if it’s negative don’t turn blue the patient will have the disease. So in exam if they say the test is negative it means they have the disease.
LAD is a disease with no migration, at age 18 you supose yo migrate from house (CD18), so you stay in home like a baby more time that supose (late umbilicak cord separation). Like if thist helps you
This content and your amazing efforts to make everyone understand this ...are grreatttt ....thank you for teaching such helpful and important information
I just came across your post. My prayers are with you. May The Almighty place him among the highest ranks in Paradise and may you and your family be blessed with the strength to bear this loss and emerge from it stronger.
I’m finding the pathophysiology of the infection process difficult to understand, like when does Th17 come into effect and how does it lead to Th1 or Th2? I think a lot of text books and stuff teach each part of immunology like T and B cell separate, then antibodies, then complements etc. but nothing tries to explain the whole process as a whole. I’ve gone through First Aid and General Principles Immunology section and I still don’t understand how everything is co-ordinated…
Does the hydrogen peroxide come from the infective organism in catalase negative infections? In CGD they can’t make it themselves right? Awesome video thank you!
Leukocyte adhesion deficiency can be triggered by vaccine or infection disease such Varicella, Ebv or Citomegalovirus? Can, in the case of chronic illness such celiac disease, someone has a normal neutrophil count while having eosinophilia ? ( Cd 56 marker highly oresent in my gut flora with no cd18/19.. Thanks
@@DirtyMedicine Thanks a lot for ur reply ! You could include the Cells that are defective ( eg B ,T or Both) , the organisms that cause infections in these , like some have viruses / fungi and other bacteria ! Just more details in an easy way. This is wonderful ,but just found it a bit concise. Thanks a ton & loads of love for ur vids :)
Yaniv Hadi I read on wikipedia that it has “lymphoma-like syndrome, in which defective white blood cells divide uncontrollably and invade many of the body's organs. The accelerated phase is associated with fever, episodes of abnormal bleeding, overwhelming infections, and organ failure” but the histiocytosis part eludes me
