View topic ↗Lung Cancer
Overview Lung cancer is a malignant tumour arising from cells within the lungs or bronchi. Two main groups: Non-small cell lung cancer (NSCLC): approximately 85% Adenocarcinoma Squamous cell carcinoma Large-cell carcinoma Small cell lung cancer (SCLC): approximately 15% More aggressive, with early nodal and distant metastasis . Lung cancer is the leading cause of cancer…
View topic ↗Kawasaki Disease
Overview Kawasaki disease is an acute systemic vasculitis affecting small and medium-sized vessels predominantly affecting children under 5 years old. It is the leading cause of acquired heart disease in children in developed countries. Kawasaki is often self-limiting, but 20–25% risk of coronary artery aneurysms if untreated 1 . Vasculitis : Inflammation of blood vessel…
View topic ↗Hydroxyapatite Deposition Disease
Overview Hydroxyapatite Deposition Disease (HADD) is a crystal-induced tendinopathy caused by the deposition of hydroxyapatite (HA) crystals, typically in periarticular soft tissues, especially tendons and bursae. The shoulder (supraspinatus tendon) is most commonly affected. It often presents between ages 30–60, more frequently in women. While often asymptomatic, it can cause acute pain and functional limitation…
View topic ↗Coeliac Disease
Overview Coeliac disease is a systemic autoimmune disease triggered (T-lymphocytes) by dietary gluten peptides found in wheat, rye, barley, and related grains. Immune activation in the small intestine leads to villous atrophy, hypertrophy of the intestinal crypts, and increased numbers of lymphocytes in the epithelium and lamina propria. Locally these changes lead to gastrointestinal symptoms and malabsorption.…
View topic ↗Endometrial Cancer
Overview Endometrial carcinoma is an epithelial malignancy of the uterine corpus mucosa, usually an adenocarcinoma. Endometrial carcinoma is the most common female genital tract malignancy. Postmenopausal bleeding always needs to be investigated because it can indicate malignant disorders and premalignant conditions, such as endometrial hyperplasia. The most common etiology of postmenopausal bleeding is atrophic endometritis or vaginitis. Menopause:…
View topic ↗Amyloidosis (Overview)
Overview Amyloidosis is a disorder in which misfolded proteins aggregate into insoluble beta-pleated sheet fibrils and deposit extracellularly in tissues, leading to progressive organ dysfunction. It may be systemic or localized . In current practice, the most clinically important systemic forms are AL (light-chain), AA (serum amyloid A), and ATTR (transthyretin; hereditary or wild-type) .…

Introduction to Skin Anatomy and Physiology
Explore the basic structure and function of the skin, the body's largest organ and first line of defense. This video introduces key skin layers, cell types, and physiological roles in protection, sensation, and temperature regulation.
Glucocorticoid Induced Osteoporosis and Fractures – mechanism and pathophysiology of fractures
Glucocorticoids are used in many inflammatory, autoimmune conditions. While being used to treat an underlying disease gluocorticoids are associated with an appreciable risk of bone loss and increases risk of fracture, which is most pronounced in the first few months of use. In general risk of fracture increases with age, dose and duration of use.…

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.
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.
Cerebral Aneurysm
Overview Cerebral (Intracranial) aneurysm is a focal dilation of an intracranial artery due to weakness of the arterial wall. It occurs in roughly 1-5% of adults and can lead to permanent disability. The most common type is a saccular “berry” aneurysm. Most common location is anterior communicating artery. Cerebral aneurysms are typically asymptomatic until rupture,…
