Henoch–Schönlein Purpura (IgA Vasculitis)
Overview Henoch–Schönlein purpura (HSP), now termed IgA vasculitis, is the most common systemic vasculitis in children, characterised by IgA1-dominant immune complex deposition in small vessels, particularly affecting the skin, joints, gastrointestinal tract, and kidneys. It predominantly occurs in children aged 3–10 years, with a slight male predominance, and often follows an upper respiratory tract infection.…

VEXAS Syndrome
Overview VEXAS syndrome is a late-onset, adult autoinflammatory disease caused by acquired somatic mutations in the UBA1 gene, leading to dysregulated innate immunity, systemic inflammation, and overlapping haematologic and rheumatologic manifestations. VEXAS stands for Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic. It predominantly affects older males due to its X-linked nature and typically presents with refractory…

Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…

Supraventricular Tachycardia
Overview The term supraventricular tachycardia (SVT), whilst often used synonymously with AV nodal re-entry tachycardia (AVNRT), can be used to refer to any tachydysrhythmia arising from above the level of the Bundle of His. Different types of SVT arise from or are propagated by the atria or AV node, typically producing a narrow-complex tachycardia (unless aberrant conduction is present). Classification…

Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.





See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
“The notes I make during his videos help me retain everything better.
“The drawings are amazing and super easy to remember.
Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
