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,…

Microscopic Polyangiitis
Overview Microscopic polyangiitis (MPA) is a small-vessel necrotizing vasculitis, commonly associated with myeloperoxidase-ANCA (MPO-ANCA) positivity. It typically presents with glomerulonephritis and pulmonary capillaritis, but does not involve granulomatous inflammation, distinguishing it from GPA.Incidence: ~3–24 cases per million annually; more common in middle-aged adults and slightly more frequent in males. 1 MPO-ANCA (Myeloperoxidase-ANCA): An autoantibody typically…

Acute Liver (Hepatic) Failure
Overview Acute liver failure is a rare but life-threatening critical illness that occurs most often in patients who do not have preexisting liver disease. Acute liver failure is seen most commonly in previously healthy adults in their 30s and presents unique challenges in clinical management. The clinical presentation usually includes hepatic dysfunction, abnormal liver biochemical…

Chronic Intestinal Ischaemia
Overview Chronic intestinal ischaemia, more commonly called chronic mesenteric ischaemia , results from an inadequate increase in intestinal blood flow after eating. It is usually caused by atherosclerotic narrowing of one or more mesenteric arteries. Patients classically develop recurrent postprandial abdominal pain, leading to reduced food intake, fear of eating and progressive weight loss. Diagnosis…

Cardiac Tamponade
Overview Cardiac tamponade is a life-threatening cardiovascular emergency caused by the accumulation of fluid, blood, pus, or gas within the pericardial sac. This accumulation causes a critical elevation in intrapericardial pressure that exceeds normal cardiac diastolic filling pressures, resulting in compression of the heart chambers, severely impaired diastolic filling, reduced stroke volume, and cardiac output…

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)
Overview Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited cardiac channelopathy in which physical exertion or acute emotion provokes ventricular arrhythmias. The heart is usually structurally normal and the resting electrocardiogram (ECG) is often normal. During adrenergic stress, ventricular ectopy may progress to bidirectional or polymorphic ventricular tachycardia (VT), ventricular fibrillation and sudden cardiac death.…

Addison's Disease
Overview Addison's disease is a disease characterised by adrenal insufficiency. Adrenal insufficiency results in a decrease of the adrenal gland hormones: mineralocorticoids, glucocorticoids and to an extent androgens. There are many causes of addison's disease. The most common cause in the developed world is autoimmune (approximately 70% cases). Signs and symptoms of adrenal sufficiency don't…

Apoptosis vs necrosis and other forms of cell death
Discover the key differences between apoptosis, necrosis, and other forms of cell death in this clear and informative medical video. Learn how these processes impact the body, their underlying mechanisms, and their roles in health and disease. Perfect for students, healthcare professionals, and anyone interested in understanding cell biology and pathology.

Endocrinology – Renal Hormones
Explore the key renal hormones—renin, erythropoietin, and calcitriol—and their roles in blood pressure regulation, red blood cell production, and calcium balance. This video offers a clear overview of how the kidneys function as vital endocrine organs.

Overview of Fluid and Electrolyte Physiology (Fluid Compartment)
This video offers a clear overview of fluid and electrolyte physiology, focusing on the body's major fluid compartments and their roles in homeostasis. Learn how water and electrolytes are distributed, regulated, and clinically significant in health and disease.
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.
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…
