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…

Antiphospholipid Syndrome (APS)
Overview Antiphospholipid Syndrome (APS) is an acquired autoimmune thrombophilia characterized by recurrent venous or arterial thromboses and/or pregnancy morbidity in the presence of persistent antiphospholipid antibodies (aPL). APS may occur as a primary condition or secondary to systemic lupus erythematosus (SLE). Prevalence of aPL in the general population is ~2%, but true APS is rare…

DiGeorge Syndrome
Overview DiGeorge syndrome (22q11.2 deletion syndrome) is a congenital immunodeficiency and multisystem disorder caused by a microdeletion on chromosome 22. It leads to defective development of the third and fourth pharyngeal pouches, resulting in thymic hypoplasia/aplasia, hypocalcaemia due to parathyroid hypoplasia, and congenital heart defects. Prevalence is estimated at 1 in 4000 live births. Clinical…

Tarsal Tunnel Syndrome
Overview Tarsal Tunnel Syndrome (TTS), also known as posterior tibial nerve neuralgia, is an entrapment neuropathy caused by compression of the tibial nerve or its terminal branches within the fibro-osseous tarsal tunnel beneath the flexor retinaculum on the medial side of the ankle. It represents the lower extremity analogue of Carpal Tunnel Syndrome. Because the…

Acute Appendicitis
Overview Acute appendicitis is an acute inflammation of the vermiform (worm-like) appendix. It is mainly caused by obstruction of the lumen of the appendix by stool, infective agents or lymphoid hyperplasia. Acute appendicits is the most common abdominal surgical emergency in the world, with a lifetime risk of 6.9% in females and 8.6% in males.…

Chronic Recurrent Multifocal Osteomyelitis
Overview Chronic Recurrent Multifocal Osteomyelitis (CRMO), also referred to as Chronic Non-bacterial Osteomyelitis (CNO), is a rare, autoinflammatory bone disease primarily affecting children and adolescents. It is characterized by sterile, non-infectious, inflammatory bone lesions that follow a chronic, waxing-and-waning clinical course. The disease results from an innate immune dysregulation featuring unbalanced pro-inflammatory cytokine production, leading…

Explanations learners return to.
Human immunodeficiency virus (HIV) – life cycle, pathophysiology, investigations, diagnosis and AIDS
Explore the life cycle and pathophysiology of Human Immunodeficiency Virus (HIV), from viral entry and replication to immune system destruction. This video also covers diagnostic tests, clinical investigations, and how untreated HIV progresses to Acquired Immunodeficiency Syndrome (AIDS).
Myasthenia Gravis – symptoms, pathophysiology, investigations, treatment
Learn about myasthenia gravis, an autoimmune neuromuscular disorder characterized by fluctuating muscle weakness due to impaired neuromuscular transmission. This video covers its symptoms, underlying pathophysiology, diagnostic investigations, and available treatment options to manage the condition.
AVRNT (atrioventricular re-entry tachycardia) – causes, pathophysiology, treatment
Discover atrioventricular re-entry tachycardia (AVRNT), a common type of supraventricular tachycardia caused by abnormal electrical conduction within or near the AV node. This video explains its causes, re-entry circuit mechanism, clinical presentation, and treatment options including vagal maneuvers, medications, and ablation therapy.
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.
Juvenile Idiopathic Arthritis (JIA)
Overview Juvenile Idiopathic Arthritis (JIA) is an umbrella term encompassing a heterogeneous group of chronic inflammatory arthritides of unknown etiology presenting in children under 16 years of age. It represents the most common chronic pediatric rheumatic disease, with an estimated prevalence of 1 in 1,000 children. To meet the diagnostic criteria, arthritis must persist for…
