Polycystic Kidney Disease
Overview The polycystic kidney diseases are among the most common life-threatening inherited diseases worldwide and frequently cause kidney failure. Autosomal dominant polycystic kidney disease (ADPKD) is seen predominantly in adults, whereas autosomal recessive polycystic kidney disease (ARPKD) is mainly a disease of childhood. For ADPKD, screening asymptomatic at-risk adults with a family history by ultrasound…

COPD
Overview The diagnosis of COPD is usually limited to individuals who have chronic airflow obstruction associated with tobacco smoke or some other noxious inhalant, and it is usually not difficult to distinguish it from other causes of chronic airflow obstruction. The most commonly associated clinical disorders associated with COPD are emphysema and chronic bronchitis. Chronic…

Piriformis Syndrome
Overview Piriformis syndrome describes buttock pain attributed to irritation or entrapment of the sciatic nerve near the piriformis muscle. Pain may radiate down the back of the thigh and resemble lumbar sciatica. Prolonged sitting often aggravates symptoms. Diagnosis can be difficult because buttock and leg pain have several possible causes and there is no single…

This video explains what causes gout (urate crystals triggering joint inflammation), how to recognize a gout flare (red, hot, swollen, painful joints—often the big toe), and the diagnostic steps doctors use, including…
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.

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…
