Benign Prostatic Hyperplasia
Overview Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate gland. There is an increase in stromal and glandular components. Anatomy The prostate is an male organ that sits inferior to the bladder and surrounds the first part of the urethra. It is oval shaped and approximately 4cm thick. The prostate gland is…
View topic ↗Mixed Connective Tissue Disease (MCTD)
Overview MCTD is a systemic autoimmune rheumatic disease characterized by overlapping clinical features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), polymyositis, with rheumatoid arthritis with high titres of anti-U1 RNP antibodies. It typically affects women aged 20–40 years. Prevalence is estimated at 3.8 per 100,000; more common in females (F:M ~9:1). The disease course…
View topic ↗AC Joint Separation
Overview Acromioclavicular (AC) joint separation is a common shoulder injury, usually sustained from direct trauma such as a fall onto the tip of the shoulder. It involves varying degrees of injury to the stabilising structures of the AC joint — primarily the acromioclavicular and coracoclavicular ligaments. Clinical presentation ranges from localised tenderness and mild pain…
View topic ↗Renal Cell Carcinoma
Overview Renal cell carcinomas (originate within the renal cortex) are responsible for 85% of all primary renal neoplasms. Transitional cell carcinomas of the renal pelvis are the next most common (~8%). Renal medullary carcinoma is a rare form of RCC seen in sickle cell disease. The most common pathological type of renal cell carcinoma is clear cell…
View topic ↗Cardiac Arrest (including post-arrest care)
Overview Cardiac arrest is a state of circulatory failure due to a loss of cardiac systolic function. It is the result of 4 specific cardiac rhythm disturbances: Ventricular fibrillation Pulseless ventricular tachycardia Pulseless Electrical activity Asystole Epidemiology Survival is estimated at <20% for patients presenting out-of-hospital with VF, and <10% overall for patients presenting with…
View topic ↗Acute Diabetes Complication (DKA, HHS, Hypoglycaemia)
Diabetic Ketoacidosis Ketoacidosis: A condition resulting from deficient insulin availability, leading to lipid oxidation and metabolism rather than glucose metabolism. The insulin absence results in free fatty acid (FFA) released from adipose tissue and in unregulated hepatic FFA oxidation and ketogenesis. Type I Diabetes: Autoimmune disease where there is attack of beta cells of the…
View topic ↗Bladder Carcinoma
Mainly focusing on Transitional cell tumours Overview Three main types of bladder carcinoma Transitional cell carcinoma (Most common) Squamous cell carcinoma Adenocarcinoma (Rare) Transitional cell tumours can affect any part of the urinary epithelium. It is the second most common urological malignancy (Renal Adenocarcinoma is the most common, bladder adenocarcinoma is rare ) and is one…

The Human Vertebra (spine and backbone)
Explore the structure and function of the human vertebra, the building blocks of the spine and backbone, in this easy-to-follow medical video. Learn about the different regions of the spine, common vertebral conditions, and their role in supporting movement and protecting the spinal cord. Ideal for students, patients, and anyone interested in understanding spinal health.

Sulphasalazine (DMARD) – Pharmacology, mechanism of action, metabolism, side effects
Learn about sulfasalazine, a disease-modifying antirheumatic drug (DMARD) used to treat inflammatory conditions like rheumatoid arthritis and IBD. This video explains its pharmacology, mechanism of action, metabolism, and potential side effects including gastrointestinal upset and hypersensitivity reactions.

Physiology of Vomiting
Explore the physiology of vomiting, including the role of the vomiting center, chemoreceptor trigger zone, and involved neural pathways. This video explains how sensory inputs, toxins, and gastrointestinal signals coordinate to initiate and control the emetic response.
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,…
