Gastric Antral Vascular Ectasia (GAVE)
Overview Gastric antral vascular ectasia (GAVE, “watermelon stomach”) is a rare but important cause of non-variceal upper gastrointestinal bleeding, often presenting with chronic iron-deficiency anaemia or recurrent overt bleeding in older adults, particularly women [1–4]. It is frequently associated with systemic conditions such as liver cirrhosis (~30% of cases) and autoimmune/connective-tissue disease (especially systemic sclerosis).…

Stroke (Ischaemic and Haemorrhagic)
Overview Third most common cause of death worldwide and most common cause of neurological disability. It is subdivided into ischaemic stroke (caused by vascular occlusion or stenosis) and haemorrhagic stroke (caused by vascular rupture, resulting in intra-parenchymal and/or subarachnoid haemorrhage). Stroke: Acute onset of a focal neurologic deficit due to a cerebral infarction or hemorrhage. Transient Ischaemic…

Polymyalgia Rheumatica (PMR)
Overview Polymyalgia rheumatica is a common inflammatory condition affecting older adults, typically over 50 years of age, characterised by pain and stiffness in the shoulder and pelvic girdles. It is strongly associated with elevated inflammatory markers and responds dramatically to low-dose corticosteroids. PMR is a clinical diagnosis and can mimic other rheumatic or non-rheumatic disorders.…

Catastrophic Antiphospholipid Syndrome (CAPS)
Overview Catastrophic antiphospholipid syndrome (CAPS) is a rare, life-threatening form of antiphospholipid syndrome (APS) characterised by rapidly developing thrombosis affecting multiple organs, typically over days. Small-vessel thrombosis and thrombotic microangiopathy are prominent, although large-vessel arterial or venous thromboses may occur simultaneously. 1 CAPS is a medical emergency . The combination of widespread thrombosis, systemic inflammation…

Leukaemia
Overview Leukemia is a common malignancy in children and adults that occurs when alterations in normal cell regulatory processes cause uncontrolled proliferation of hematopoietic stem cells in the bone marrow. Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow Acute Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow that develops…

Acne
Overview Acne vulgaris is a chronic inflammatory disease of the pilosebaceous units, most commonly involving the face, neck, chest, and back. It is characterized by the formation of comedones, papules, pustules, nodules, and, in severe cases, deep scars. While classically viewed as a rite of passage during adolescence, acne can persist into or present for…

Posterior Triangle of the neck—Boundaries, Contents, Nerve Blocks & Surgical Landmarks
Explore the posterior triangle of the neck—its borders, subdivisions, key nerves and vessels, and critical clinical implications. In this concise anatomy video you’ll learn the precise boundaries of the posterior triangle (sternocleidomastoid, trapezius, clavicle), how the omohyoid divides it into the occipital and subclavian (omoclavicular) triangles, and which structures lie within each region. Discover the…
Human Metabolism Map VII – Fatty Acid Degradation
Learn the key steps of Fatty Acid Degradation (β-oxidation) in this video from the Human Metabolism Map series. Understand how fatty acids are broken down for energy, including enzyme actions, mitochondrial transport, and clinical significance—essential for biochemistry exams and metabolic clarity.
Asthma Pathophysiology
Explore asthma, a chronic inflammatory airway disease characterized by reversible airway obstruction and hyperresponsiveness. This video explains its key signs and symptoms, underlying pathophysiology, and how these contribute to breathing difficulties.
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.

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.
Cervical Stinger/Burner Injuries
Overview A cervical stinger or burner is a transient peripheral nerve injury caused by traction, compression or direct trauma to a cervical nerve root or the upper brachial plexus. It typically occurs during collision or contact sport and produces sudden unilateral burning, stinging or electric-shock pain radiating from the neck or shoulder into the arm.…
