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,…

Somatoform Disorders
Overview Doctors and patients often experience frustration and helplessness in consultations around medically unexplained symptoms. Up to 50 percent of primary care patients present with physical symptoms that cannot be explained by a general medical condition. Although most do not meet the strict psychiatric diagnostic criteria for one of the somatoform disorders, they can be referred to…

Haemorrhoids overview
Discover the key facts about haemorrhoids, including their pathophysiology, symptoms, and how they're diagnosed and managed. This video covers internal vs external haemorrhoids, contributing factors, and both medical and surgical treatment options.
Septic Arthritis – Overview (causes, pathophysiology, treatment)
Septic arthritis is a medical emergency caused by joint infection leading to rapid cartilage destruction. This video explains the causes, key pathophysiology, clinical presentation, and urgent treatment strategies to prevent joint damage.

Febrile neutropenia is a potentially life-threatening oncologic emergency—learn its causes, diagnosis, and immediate management to protect chemotherapy patients. In this concise, clinically focused video you’ll understand what febrile neutropenia is, why neutrophils matter, and how chemotherapy-induced neutropenia (often 5–10 days after treatment) predisposes patients to rapid sepsis. Key concepts covered include neutrophil biology (primary and…
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.
Allergic Conjunctivitis
Overview Allergic conjunctivitis is inflammation of the conjunctiva caused by hypersensitivity to an allergen. It usually presents with bilateral ocular itching, redness, watering and conjunctival swelling , often alongside allergic rhinitis, asthma or atopic dermatitis. 1,2 Seasonal and perennial allergic conjunctivitis are common and generally do not threaten vision. Vernal keratoconjunctivitis and atopic keratoconjunctivitis are…
