Prostatitis
Overview Prostatitis refers to a spectrum of conditions involving inflammation of the prostate gland, ranging from acute bacterial infection to chronic pelvic pain syndromes.

Glomerulonephritis
Overview Glomerulonephritis is inflammation of the glomerulus. Glomerulonephritis is classified by clinical syndrome/presentation (e.g. nephritic or nephrotic syndrome), histological appearance , or by aetiology. We will divide glomerulonephritis broadly into two broad types: Nephritic glomerulonephritis and nephrotic glormerulonephritis. Classification Two Types of Glomerular disease: Nephrotic Syndrome Nephritic Syndrome DIFFERENCE BETWEEN NEPHROTIC AND NEPHRITIS SYNDROME …

Febrile Seizure
Overview Seizures are a common occurrence in children. 8% will have at least one seizure by 15 years of age. A seizure is the result of an abnormal paroxysmal discharge by cerebral neurons. Many underlying conditions and neurological challenges may provoke seizures, and in over 50% of children seizures are isolated events associated with either a fever…

Varicose Veins
Overview Varivose veins (VV) are long, torturous and dilated don't veins of the superficial venous system. There is a spectrum ranging from telangiectasias (dilated interdermal venules less than 1 mm), through to reticular veins (non-palpable subdermal veins 1–3 mm) to varicose veins (greater than 3 mm). 35% of the general population affected. The venous system of…

Shingles (Herpes Zoster)
Overview Shingles is reactivation of latent varicella-zoster virus (VZV) following previous chickenpox or, less commonly, varicella vaccination. After primary infection, VZV remains dormant in the dorsal-root or cranial-nerve ganglia. Reactivation occurs when VZV-specific cell-mediated immunity declines. In Australia, incidence is approximately 560 cases per 100,000 people annually and increases markedly after age 50. Lifetime risk…

Valvular Heart Disease
Overview Valvular disease can come to clinical attention due to stenosis, insufficiency (regurgitation/incompetence) or both. Stenosis is the failure of a valve to open completely, which impedes forward flow. Insufficiency results from failure of a valve to close completely, thereby allows reversed flow. Doppler echocardiogram is the best technique for assessing patients with valvular heart disease, but…

Idiopathic Pulmonary Fibrosis – pathophysiology, signs and symptoms, investigation and treatment
Learn about idiopathic pulmonary fibrosis, a chronic lung disease characterized by progressive scarring of the lung tissue. This video covers its pathophysiology, clinical presentation, diagnostic approach, and current treatment strategies aimed at slowing disease progression and managing symptoms.
Inflammatory mediators and the inflammatory response
Discover the essential facts about inflammation in this comprehensive video! Learn how your body’s natural defense mechanism works to protect against injury, infection, and illness, and understand the difference between acute and chronic inflammation. We will look at how an injury triggers inflammation and the inflammatory mediators involved.

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.

Student, Neelain University
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 Radiculopathy
Overview Cervical radiculopathy is dysfunction of a cervical nerve root caused by irritation or compression as it leaves the spine. It commonly produces pain radiating from the neck into one arm, sometimes with paraesthesia, numbness, weakness or altered reflexes. A disc herniation or degenerative narrowing of the neural foramen is a common cause. Diagnosis is…
