Enteropathic Arthritis
Overview Enteropathic arthritis is a subtype of spondyloarthropathy associated with inflammatory bowel disease (IBD), particularly Crohn’s disease and ulcerative colitis. It affects up to 20% of IBD patients, with a variable presentation involving axial and/or peripheral joints. The arthritis may run parallel to intestinal disease activity or occur independently, often with enthesitis or dactylitis. It…

Eosinophilic Granulomatosis with Polyangiitis
Overview EGPA (formerly Churg-Strauss syndrome) is a rare, small-to-medium vessel necrotizing vasculitis characterized by asthma, eosinophilia, and extravascular granulomas. It commonly affects the lungs, skin, peripheral nerves, and heart. Annual incidence: ~1–3 per million; peak onset in 40s–60s; no significant gender bias. Strongly associated with MPO-ANCA positivity in ~40–60% of patients; others are ANCA-negative. Eosinophilia…

X-linked Agammaglobulinaemia (XLA / Bruton’s Disease)
Overview X-linked agammaglobulinaemia (XLA) is a rare primary immunodeficiency caused by mutations in the Bruton’s tyrosine kinase (BTK) gene , leading to failure of B-cell maturation. It results in profound hypogammaglobulinaemia and susceptibility to recurrent bacterial infections, particularly with encapsulated organisms. It usually presents after 6 months of age (once maternal IgG wanes). Prevalence is…

Neck of Femur Fracture
Overview A neck of femur fracture is a fracture through the region connecting the femoral head to the femoral shaft. It is an intracapsular fracture because most of the femoral neck lies within the hip joint capsule. Neck of femur fractures most commonly occur in older adults following a low-energy fall, often in the presence…

Acute Pancreatitis
Overview Acute pancreatitis is sudden inflammation of the pancreas caused by premature activation of pancreatic digestive enzymes within the gland. It ranges from a mild, self-limiting illness to severe necrotising pancreatitis with persistent organ failure. The most common causes are gallstones and alcohol, although hypertriglyceridaemia, medicines, procedures and metabolic disorders are also important. Acute Pancreatitis:…

Biliary Atresia
Overview Biliary atresia is a progressive fibro-inflammatory disorder of infancy in which the extrahepatic bile ducts—and variably the intrahepatic ducts—become obliterated. This prevents bile from draining from the liver, producing conjugated hyperbilirubinaemia, progressive hepatic fibrosis and, without treatment, cirrhosis and liver failure. Affected infants often appear well during the first weeks of life. Persistent jaundice…

Good places to begin
Explanations learners return to.
DNA Methylation and Cancer
Discover how DNA methylation plays a crucial role in cancer development by regulating gene expression and silencing tumor suppressor genes. This video explains the mechanisms of DNA methylation and its impact on cancer progression and potential therapeutic targets.
Skeletal System Overview
Explore the anatomy and functions of the skeletal system, including bone structure and types. This video provides a clear overview essential for understanding human movement and support.
Myology – Skeletal Muscle Contraction
Explore the process of skeletal muscle contraction, from action potential initiation to cross-bridge cycling between actin and myosin. This educational video covers the role of calcium, troponin-tropomyosin complex, and ATP—essential for mastering muscle physiology and preparing for medical exams.
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.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
