Anklylosing Spondylitis (AS)
Overview Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis that primarily affects the axial skeleton, especially the sacroiliac joints and spine. It is a subtype of the seronegative spondyloarthropathies and is characterised by inflammatory back pain, morning stiffness, and eventual spinal fusion in severe cases. AS often presents in young adults, typically males, and…

Chronic Spontaneous Urticaria +/- angioedema
Overview Chronic spontaneous urticaria (CSU) is a mast-cell–driven skin disorder defined by recurrent wheals (hives), angioedema, or both for >6 weeks without a specific external trigger , with a point prevalence around 0.5–1% and a female predominance; median disease duration is ~2–5 years, but a subset persists longer and markedly impairs quality of life and…

Atrial Fibrillation
Overview Atrial fibrillation, AF is a chaotic, irregular atrial rhythm at 300-600bpm; the AV node responds intermittently, hence an irregular ventricular rate. AF is the most common sustained dysrhythmia; characterised by absent P waves, irregularly irregular heart rate, narrow QRS (typically). It is common in the elderly. The main risk of AF is embolic stroke…

Kawasaki Disease
Overview Kawasaki disease is an acute systemic vasculitis affecting small and medium-sized vessels predominantly affecting children under 5 years old. It is the leading cause of acquired heart disease in children in developed countries. Kawasaki is often self-limiting, but 20–25% risk of coronary artery aneurysms if untreated 1 .

Wiskott–Aldrich Syndrome
Overview Wiskott–Aldrich syndrome is a rare X-linked recessive primary immunodeficiency caused by mutations in the WAS gene, leading to defective actin cytoskeleton regulation in hematopoietic cells. It presents with the triad of eczema, recurrent infections, and thrombocytopenia with small platelets. Patients are prone to autoimmunity and malignancy. Incidence is ~1 in 100,000 live male births.…

Acute Respiratory Failure
Overview Acute Respiratory Failure (ARF) is a life-threatening impairment of the respiratory system's ability to maintain adequate gas exchange. It occurs when the lungs fail to adequately oxygenate systemic arterial blood, fail to eliminate carbon dioxide produced by tissue metabolism, or both. ARF is not a disease entity in itself, but rather a sudden, critical…

Explanations learners return to.
Cluster Headaches – symptoms, pathophysiology, treatment
Cluster headache attack is an intense and severe strictly unilateral pain around the eye. It is describe as the worst ever headache, using comparisons such as childbirth, fractures and renal stones. The pain ramps up quite quickly once it starts and typically remains for 15–180 min when untreated.
Cell Cycle (Overview, Interphase)
Understand the stages of the cell cycle with a focus on interphase, where cells grow, replicate DNA, and prepare for division. This video explains the roles of G1, S, and G2 phases, and how the cell ensures accurate progression through checkpoints.
Intussusception
Learn all about Intussusception, a life-threatening cause of bowel obstruction in infants and young children. This video covers classic symptoms like currant jelly stools, diagnosis with ultrasound, and key emergency treatments every medical student should know.
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.

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…
