Author Megan Miner Armando Faigl Overview Pertussis, also known as “whooping cough”, is a contagious, acute respiratory infection caused by the bacterium Bordetella pertussis. In babies, the infection can sometimes lead to pneumonia and occasionally brain damage and can even be life threatening. Older children and adults can get whooping cough and can spread it…

Overview Bronchiolitis is often a viral cause mainly Respiratory Syncytial Virus (RSV). Bronchiolitis is the most common respiratory tract infection of neonates and is usually self-limiting. A major source of confusion of treatment is differentiating a viral bronchiolitis to asthma. In summary bronchiolitis is usually seen in infants <2yo. Asthma is seen in older children. Bronchiolitis…

Overview Behçet’s syndrome is a chronic, relapsing, multisystem inflammatory disorder and variable-vessel vasculitis characterized classically by recurrent oral ulcers, genital ulcers, ocular inflammation, and skin lesions. It can also involve the joints, vessels, nervous system, and gastrointestinal tract. The disease is most prevalent along the historic “Silk Road” region, including Turkey, the Middle East, and…
View topic ↗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,…

Approach to Fat malabsorption – signs and symptoms and causes
Understand the clinical approach to fat malabsorption by recognizing its key signs and symptoms, such as steatorrhea and weight loss. This video also explores common causes, including pancreatic insufficiency, bile acid disorders, and intestinal mucosal diseases.

Superior vena cava and azygos system – clinical anatomy
Explore the clinical anatomy of the superior vena cava and azygos system, focusing on their roles in venous return to the heart. This video also explains the causes, signs, and collateral pathways involved in superior vena cava obstruction, a critical oncologic emergency.

Baker's Cyst Knee – posterior knee swelling and pain
Baker’s cysts, also known as popliteal cysts, are among the most common knee disorders. These fluid-filled cysts develop at the back of the knee in the popliteal fossa and result from the enlargement of the gastrocnemius-semimembranosus bursa, a bursa located between the gastrocnemius and semimembranosus muscles. Baker’s cysts typically form in adults due to knee…
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.
“The notes I make during his videos help me retain everything better.
“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.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
