Croup
Overview Croup, also known as largnotracheobronchitis, is a usually self limiting upper airway viral infection causing upper airway obstruction. Croup is more common in boys than in girls, usually occurs between six and 36 months of age, and peaks during the second year of life. Croup is usually caused by viruses, which are detected in up to…

Community Acquired Pneumonia
Overview Community acquired pneumonia occur in individuals who are not in hospital (or have been in hospital in the past 48 hours) and who are not significantly immunocompromised. The World Health Organization estimates that lower respiratory tract infection is the most common infectious cause of death in the world. Choice of antibiotics are usually empirical…

Osgood Schlatter
Overview In this common disorder of adolescence the tibial tubercle becomes painful and ‘swollen’. Although often called osteochondritis and apophysitis, it is nothing more than a traction injury of the apophysis into which part of the patellar tendon is attached. Osgood-Schaltter disease typically occurs during the early adolescent growth spurt between 10-15 years of age,…

Graves' Disease
Overview Graves' disease is the most common cause of hyperthyroidism, caused by an autoimmune reaction in which TSH receptor autoantibodies stimulate the thyroid gland, leading to an increase in the production of thyroid hormones. It’s named after Dr Robert James Graves, an Irish physician who in 1835 gave one of the first thorough clinical descriptions…

Cardiogenic Shock
Overview Cardiogenic shock is a life-threatening clinical syndrome in which cardiac dysfunction causes inadequate cardiac output and tissue hypoperfusion. Hypotension is common but is not essential; patients may initially maintain blood pressure through marked vasoconstriction while organ perfusion deteriorates. 1 Acute myocardial infarction is a major cause, but cardiogenic shock may also complicate acute or…

Scaphoid Fracture
Overview Scaphoid fracture is the most common carpal bone fracture , accounting for ~60–70% of all carpal fractures. It occurs most frequently in young adults (15–40 years) following a fall on the outstretched hand (FOOSH). The scaphoid’s tenuous blood supply predisposes to non-union and avascular necrosis, especially in proximal fractures. Early recognition is essential as…

Pernicious Anaemia
Overview Pernicious Anaemia is a condition where there is lack of intrisinc factor, a glycoprotein responsible for the absorption of Vitamin B12. Vitamin B12 (Cobalamin) is an essential vitamin responsible for many physiological process in our body. Vitamin B12 deficiency causes megaloblastic anaemia and maybe accompanied by neurological abnormalities. Aetiology Pernicious Anaemia is associated with…

Emphysema Treatment
Learn about the treatment options for emphysema, including lifestyle changes, medications, pulmonary rehabilitation, and advanced therapies. This video explains how each approach helps manage symptoms, improve breathing, and slow disease progression in patients with COPD.
Mycophenolic Acid – Mycophenolate (organ transplant and DMARD) – mechanism of action, side effects
Mycophenalate is used in lupus nephritis (first line), diffuse SS but also indicated for the prophylaxis of organ rejection in patients undergoing allogeneic renal, hepatic, or cardiac transplants. In transplant patients it should be used with cyclosporine/tacrolimus and corticosteroids. Mycophenolate has a preferential inhibition of IMPDH II the rate limiting step in the de novo…
Human Metabolism Map III – Malate Aspartate Shuttle & Glycerol 3 Phosphate
Discover how the malate-aspartate and glycerol 3-phosphate shuttles transfer electrons into mitochondria to support ATP production. This video breaks down their mechanisms and significance in cellular respiration and energy metabolism.
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.

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…
