RA Related Pleural Effusion
Overview Rheumatoid pleural effusion (RPE) is an uncommon extra‑articular manifestation of rheumatoid arthritis (RA), occurring in ~2–5% of patients, more often in middle‑aged men with high rheumatoid factor (RF) titres, despite RA being more common in women. It typically presents during active disease or in patients with rheumatoid nodules, but can occasionally precede joint symptoms.…

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.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“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.
Aortic Aneurysm
Overview An aortic aneurysm is a pathological dilatation of the aorta caused by weakening of the arterial wall. It may involve the aortic root, ascending aorta, arch, descending thoracic aorta, thoracoabdominal aorta or abdominal aorta. Most aortic aneurysms are asymptomatic and are discovered incidentally or through screening. Progressive enlargement increases the risk of rupture, dissection,…
