Birth Defects
Overview Birth defects are the leading cause of perinatal and post- neonatal deaths, and result in substantial morbidity and disability in developed countries. There is a wide variety of mechanisms including genetic, environmental and multifactorial. Major birth defects affect 2–3% of live-borns, and minor birth defects affect 15%. Preventative strategies remain limited, but include maternal folic acid supplementation,…

Acute Cholecystitis
Overview Acute cholecystitis is acute inflammation of the gallbladder, usually caused by a gallstone obstructing the cystic duct. Persistent obstruction causes gallbladder distension, inflammation and possible secondary bacterial infection. Most cases are calculous, while acalculous cholecystitis occurs mainly in critically ill or severely immunocompromised patients. Cholecystectomy: surgical removal of the gallbladder. Calculous cholecystitis: gallbladder inflammation…

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 & Physiology The skin consist of three layers, from superficial…

Aneurysm
Overview An aneurysm is an abnormal localised dilatation of a blood vessel with at least 50% increase in diameter compared to its normal diameter. It is seen more often in arteries compared to veins. Aneurysms are usually asymptomatic until they are very large or they rupture. A ruptured aneurysm can cause massive bleeding and death.…

Non-Febrile Seizures (Epilepsy)
This section will mainly focus on Paediatric Epilepsy (NOT FEBRILE SEIZURES) Children and Adults can have seizures because of metabolic disturbances, trauma or being in a febrile state. This does mean they have epilepsy. Epilepsy is a condition characterised by the tendency for recurrent seizures. Presents when at least 2 unprovoked seizures occur >24 hours apart. Overview…

Meniscal Tear
Overview Medial and lateral knee joint menisci serve to transfer load and absorb shock, aid joint stability and provide lubrication. The meniscus is the most commonly injured structure in the knee joint. Acute tears occurs after axial loading combined with rotation. People may complain of a sensation of clicking or catching of the knee with…

Human Gut Microbiome
Discover how your gut microbiome—trillions of bacteria in the large intestine—shapes metabolism, immunity, and overall health. The human gut microbiota, dominated by anaerobes like Firmicutes and Bacteroidetes, ferments non-digestible carbohydrates into short-chain fatty acids (SCFAs) such as butyrate, which supply up to 70% of colonocyte energy and influence systemic metabolism, fat storage, and immune signaling.…
Piriformis Syndrome (buttock pain, siatica)
Learn about piriformis syndrome, a neuromuscular condition where the piriformis muscle compresses the sciatic nerve, causing buttock pain and radiating leg discomfort. This video explains the anatomy, symptoms, underlying causes, and strategies for diagnosis and treatment.
Granulomatosis with polyangiitis – pathophysiology and management
Granulomatosis with polyangiitis (Wegener’s) explained: learn causes, symptoms, diagnosis, and treatment of ANCA-associated vasculitis. ANCA-associated vasculitis targets small blood vessels and is driven by P-ANCA (anti-myeloperoxidase) or C-ANCA (anti-proteinase 3) antibodies; granulomatosis with polyangiitis (GPA) is the most common form and often ANCA-positive against proteinase 3. This video breaks down the hallmark Wegener’s triad—upper respiratory,…
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.
Carpal Tunnel Syndrome
Overview Carpal tunnel syndrome (CTS) is a compressive neuropathy of the median nerve as it passes beneath the transverse carpal ligament at the wrist. It is the most common peripheral nerve entrapment syndrome and typically causes nocturnal paraesthesia, numbness or pain involving the thumb, index finger, middle finger and radial half of the ring finger.…
