Anklylosing Spondylitis (AS)
Overview Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis that primarily affects the axial skeleton, especially the sacroiliac joints and spine. It is a subtype of the seronegative spondyloarthropathies and is characterised by inflammatory back pain, morning stiffness, and eventual spinal fusion in severe cases. AS often presents in young adults, typically males, and…

Myelofibrosis
Overview Myelofibrosis is a type of myeloproliferative diseasecharacterized by clonal myeloid expansion, followed by progressive fibrous connective tissue deposition in the bone marrow, resulting in bone marrow failure. Clonal evolution can also occur, with an increased risk of transformation to acute myeloid leukemia. In addition, disabling constitutional symptoms secondary to the high circulating levels of…

Cardiac Sarcoidosis
Overview Cardiac sarcoidosis is an inflammatory heart disease caused by myocardial infiltration with non-necrotising granulomas. Inflammation may subsequently resolve, recur, or progress to permanent fibrosis. The disease is often patchy and may affect the conduction system, ventricular myocardium, papillary muscles, valves, pericardium, or coronary microcirculation. 1 Cardiac involvement may occur as part of multisystem sarcoidosis…

Gastroenteritis (Infectious Diarrhoea)
Overview Infectious gastroenteritis is an intestinal illness caused by viruses, bacteria or parasites, typically producing acute diarrhoea with variable vomiting, abdominal cramps and fever. Transmission is usually faecal–oral through contaminated food or water, close contact, or contaminated surfaces. It affects all ages; infants, older adults, malnourished people and immunocompromised patients are especially vulnerable to dehydration…

Pre-menstrual Syndrome (PMS)
Overview Premenstrual syndrome is defined as recurrent moderate psychological and physical symptoms that occur during the luteal phase of menses and resolve with menstruation. Most women of reproductive age experience one or more mild emotional or physical symptoms for one to two days before the onset of menses. These symptoms, such as breast soreness and bloating,…

Blount’s Disease
Overview Blount's disease, also called tibia vara, is a developmental growth disorder of the posteromedial proximal tibial physis. Asymmetric growth produces progressive genu varum centred below the knee, commonly with procurvatum, internal tibial torsion and relative shortening. It differs from physiological bowing because the deformity persists or progresses rather than following normal spontaneous correction.¹,² Early-onset…

Pulmonary Embolism
Overview Pulmonary embolism occurs most often from a dislodged thrombus from the lower limb (DVT). The embolus travels towards the lung and becomes lodged in the pulmonary artery resulting in infarction of the lung tissue. Pulmonary Embolism: Deep Vein Thrombosis (DVT): Blood clot in the deep venous system that usually affects the lower extremities or…

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.
Osteonecrosis of the Hip (femoral head) – Avascular Necrosis
Understand osteonecrosis of the hip (avascular necrosis of the femoral head), focusing on its causes, pathophysiology, and clinical presentation. This video also discusses diagnostic imaging and treatment options to prevent joint collapse and preserve mobility.
Why should we not waste food? A look into food wastage and security
Discover the impact of food wastage on global food security and the environment, highlighting why reducing waste is crucial for a sustainable future. This video explores the causes, consequences, and practical solutions to minimize food loss and ensure equitable resource use.
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.
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…
