Asthma
Overview Asthma is a chronic airway inflammation disorder due to complex interactions between inflammatory cells, mediators and airway cells. In young children in whom lung function testing is not feasible, including most preschool children, asthma is defined by the presence of variable respiratory symptoms. Asthma is one of the most common causes of presentation to the Emergency…

Gout
Overview Gout is a common inflammatory arthritis that is increasing in prevalence. Gout (monosodium urate crystal deposition disease) is characterized biochemically by extracellular fluid urate saturation. Tends to occur earlier in life in men than women, and is rare in childhood. Prevalence is increasing. It is associated with many serious comorbidities such as hypertension, chronic kidney disease,…

Eosinophilic Granulomatosis with Polyangiitis
Overview EGPA (formerly Churg-Strauss syndrome) is a rare, small-to-medium vessel necrotizing vasculitis characterized by asthma, eosinophilia, and extravascular granulomas. It commonly affects the lungs, skin, peripheral nerves, and heart. Annual incidence: ~1–3 per million; peak onset in 40s–60s; no significant gender bias. Strongly associated with MPO-ANCA positivity in ~40–60% of patients; others are ANCA-negative. Eosinophilia…

Inflammatory SI Joint Pain (Sacroiliitis) vs Mechanical: Key Clues
Discover how to recognize sacroiliitis, its causes, imaging signs, and key mimics to improve diagnosis and patient care. In this video we define sacroiliitis, explain primary causes like axial spondyloarthritis (including ankylosing spondylitis), psoriatic arthritis, IBD-related spondyloarthritis, and reactive arthritis, and show how inflammatory back pain presents (insidious onset, night pain, morning stiffness, improves with…
Epididymitis Explained | Causes, Symptoms, Diagnosis and Treatment
Epididymitis is inflammation of the epididymis, the structure behind the testis that stores and transports sperm. It is usually caused by infection, with sexually transmitted organisms more common in younger men and urinary tract bacteria more common in older men. Typical features include unilateral scrotal pain, swelling, tenderness, and redness, sometimes with urinary symptoms or…
Thrombocytopaenia (low platelets) Overview – platelet physiology, classification, pathophysiology
Learn the basics of thrombocytopaenia, including platelet physiology, classification, and the key mechanisms behind low platelet counts. This video breaks down common causes and how they affect clotting and overall hemostasis.
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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
