Infective Endocarditis
Overview Infective endocarditis is a condition which occurs in the setting of bacteraemia whereby endothelial surfaces of the heart, such as valvular structures, become infected. It can present acutely or subacutely, and is often associated with fevers, new heart murmurs, constitutional symptoms and embolic phenomena. The classical organism associated is Staphylcoccus aureus, however there are…
View topic ↗ACL Tear
Overview Anterior cruciate ligament (ACL) tear is one of the most common knee injuries, particularly in young athletes involved in pivoting sports (soccer, basketball, skiing). ACL injuries account for ~50% of all knee ligament injuries, with an incidence of ~68 per 100,000 annually, more common in females due to anatomical and biomechanical risk factors. ACL…
View topic ↗Pneumonia
Overview Pneumonia is infection in the lower respiratory tract and is characterised by fevers, purulent sputum, leucocytosis, low oxygen levels and new lung infiltrates (consolidation) on radiographic imaging. The infection is identified by the site of consolidation. Consolidation is where the lung tissue is filled with fluid (ie. water, blood, pus, microbes). Types of pneumonia…
View topic ↗Nephrotic Syndrome
Overview Nephrotic syndrome is a relatively rare but important manifestation of kidney disease.Nephrotic syndrome classically presents with heavy proteinuria , minimal hematuria, hypoalbuminemia, hypercholesterolemia, edema , and hypertension. In general, all patients with hypercholesterolemia secondary to nephrotic syndrome should be treated with lipid-lowering agents because they are at increased risk for cardiovascular disease. Nephrotic syndrome…
View topic ↗Melanoma
Overview Melanoma accounts for 4 percent of all dermatological cancer. Melanoma has the highest mortality rate of all dermatological cancers, only 14 percent of patients with metastatic melanoma survive for five years. Melanoma is one of the most common cancers in young adults. Melanoma Overview Anatomy and Physiology The skin consist of three layers, from superficial…
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) .…
View topic ↗Henoch–Schönlein Purpura (IgA Vasculitis)
Overview Henoch–Schönlein purpura (HSP), now termed IgA vasculitis, is the most common systemic vasculitis in children, characterised by IgA1-dominant immune complex deposition in small vessels, particularly affecting the skin, joints, gastrointestinal tract, and kidneys. It predominantly occurs in children aged 3–10 years, with a slight male predominance, and often follows an upper respiratory tract infection.…

Methotrexate – Pharmacology (DMARDs, mechanism of action, side effects)
Learn about methotrexate, a key disease-modifying antirheumatic drug (DMARD) used to treat autoimmune conditions and certain cancers. This video explains its mechanism of action, pharmacologic properties, and common side effects such as liver toxicity and bone marrow suppression.

Approach to a Thyroid Nodule – causes, investigation and treatment
Understand the clinical approach to a thyroid nodule, from identifying potential causes to selecting appropriate investigations. This video outlines key diagnostic tools such as ultrasound and fine-needle aspiration, along with treatment strategies based on risk and pathology.

Understanding Asthma – pathophysiology and treatment
Asthma explained: understand causes, triggers, symptoms, diagnosis, and practical treatment steps to manage acute and chronic attacks. This concise video breaks down asthma’s inflammatory mechanisms, common triggers (allergens, smoke, cold air, medications, exercise), and why bronchial hyper-responsiveness leads to wheeze, cough, and breathlessness. You’ll learn how asthma develops—from airway inflammation, mucus hypersecretion, and smooth-muscle contraction…
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.
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,…
