Basic Calcium Phosphate Disease / Milwaukee Shoulder Syndrome
Overview Basic Calcium Phosphate (BCP) disease is a crystal-associated arthropathy characterized by deposition of BCP crystals in periarticular and intra-articular tissues. A severe clinical presentation of BCP disease is Milwaukee Shoulder Syndrome, which typically affects elderly women, leading to rapid joint destruction, massive rotator cuff tears, and non-inflammatory joint effusion. It often involves the shoulder,…

Acute Exacerbation of COPD
Overview An acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is an acute worsening of dyspnoea and/or cough and sputum over fewer than 14 days, often associated with increased airway inflammation triggered by infection, pollution or another insult. 1 It represents a clinically important change from the patient’s usual day-to-day variation and may require additional…

Cardiac Arrest (including post-arrest care)
Overview Cardiac arrest is a state of circulatory failure due to a loss of cardiac systolic function. It is the result of 4 specific cardiac rhythm disturbances: Ventricular fibrillation Pulseless ventricular tachycardia Pulseless Electrical activity Asystole Epidemiology Survival is estimated at <20% for patients presenting out-of-hospital with VF, and <10% overall for patients presenting with…

Diabetes Insipidus
56 year old lady recurrent presentations to your practice for polyuria and increased thirst. Random serum glucose and urinary glucose have returned normal. Patient has otherwise been well, complains of no dysuria, haematuria, fevers or night sweats . Overview Diabetes Insipidus (DI) is associated with inadequate arginine vasopressin (known as antidiuretic hormone) secretion or renal…

Guillain–Barré Syndrome
Overview Guillain-Barré Syndrome (GBS) is an acute, immune-mediated polyneuropathy typically triggered by a preceding gastrointestinal or respiratory infection. It is characterised by an autoimmune attack on the peripheral nerves, leading to mainly demyelination but also axonal degeneration, which impairs nerve conduction and causes muscle weakness and paralysis. GBS affects about 1–2 per 100,000 people annually.…

Aortic Stenosis
Overview Aortic valve stenosis is characterised by obstruction of left ventricular outflow, resulting in inadequate cardiac output, decreased exercise capacity, heart failure, and death from cardiovascular causes. Mild to moderate aortic stenosis is usually a symptomatic, but occasionally can be found on routine examination Locations of stenosis – Valvular (common), supravalvular and subvalvular Aortic Stenosis…

Sensory Tracts – Dorsal Column (Medial lemniscus) Pathway
Learn how the dorsal column–medial lemniscus pathway transmits fine touch, vibration, and proprioception from the body to the brain. This video breaks down its anatomy, function, and clinical relevance in sensory deficits.
(Bacterial) Meningitis Pathophysiology
Learn the key mechanisms behind bacterial meningitis, including how pathogens invade the central nervous system and trigger inflammation. This video covers the pathophysiology, clinical implications, and diagnostic relevance of this life-threatening condition.
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.

Student, Neelain University
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,…
