Takayasu Arteritis
Overview Takayasu arteritis is a rare, chronic large-vessel vasculitis primarily affecting the aorta and its major branches, leading to stenosis, occlusion, or aneurysm formation. It most commonly affects young women (<40 years), particularly of Asian descent. The global incidence is estimated at 1–2 per million per year, with a female predominance (F:M ~9:1). It is…

Common Variable Immunodeficiency
Overview Common Variable Immunodeficiency (CVID) is the most frequent clinically significant primary antibody deficiency, characterised by hypogammaglobulinaemia and impaired antibody responses. It typically presents with recurrent bacterial infections, autoimmunity, granulomatous disease, and an increased risk of malignancy. CVID affects both sexes equally, with a prevalence of ~1 in 25,000–50,000 individuals. Diagnosis is often delayed, with…

Neonatal Respiratory Distress Syndrome
Overview Neonatal respiratory distress syndrome (RDS) , previously called hyaline membrane disease, is a disorder caused primarily by pulmonary surfactant deficiency and structural lung immaturity. It occurs mainly in premature infants and presents shortly after birth with tachypnoea, grunting, chest recession and increasing oxygen requirements. Severity increases as gestational age decreases. Neonatal RDS is different…

Myasthenia Gravis
Overview Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder where antibodies target acetylcholine receptors (AChR) or MuSK proteins at the post-synaptic membrane, impairing neuromuscular transmission and causing muscle weakness Myasthenia Gravis (MG) is a rare autoimmune disorder marked by fluctuating muscle weakness that worsens with activity and improves with rest, commonly affecting the ocular…
View topic ↗Dupuytren’s Contracture
Overview Dupuytren’s disease is a benign fibroproliferative disorder affecting the palmar fascia. Abnormal collagen deposition produces firm nodules and cords beneath the skin of the palm, which may progressively shorten and pull one or more fingers into flexion. The ring and little fingers are most commonly affected. Contracture usually develops slowly over months or years…

Thyroiditis
Overview Thyroiditis: Varied group of disorder all characterized by some form of thyroid inflammation Hyperthyroidism: denote conditions in which hyperfunction of the thyroid leads to thyrotoxicosis. Hypothyroidism: Variety of abnormalities that cause insufficient secretion of thyroid hormones. The most common cause is autoimmune thyroid disease Thyrotoxicosis: denotes the clinical, physiological, and biochemical findings that result…

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…

Fat (lipid) digestion and absorption physiology
Explore the physiology of fat digestion and absorption, from emulsification by bile salts to breakdown by pancreatic enzymes. This video explains how lipids are processed, absorbed in the small intestine, and transported via chylomicrons into the lymphatic system.

Vitamin B12 Digestion and Absorption & Pernicious Anaemia
Vitamin B12 absorption explained: learn how intrinsic factor, R‑binder (haptocorrin/transcobalamin I), and ileal receptors enable cobalamin uptake and why pernicious anemia blocks it. This clear walkthrough covers vitamin B12 (cobalamin) sources, gastric digestion, and the molecular steps that let B12 enter the bloodstream. Watch to understand how dietary B12 from meat, eggs, fish, and dairy…

Monkeypox virus overview
Learn about the Monkeypox virus, a zoonotic infection related to smallpox that causes fever, rash, and lymphadenopathy. This video explains its transmission, symptoms, clinical course, and current strategies for diagnosis, prevention, and treatment.
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.
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…
