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…

Mitral Regurgitation (Incompetence)
Overview Mitral regurgitation (MR), which is also known as mitral insufficiency, is a common heart valve disorder. When MR is present, blood leaks backwards through the mitral valve when the heart contracts. This reduces the amount of blood that is pumped out to the body. Patients with acute mitral regurgitation (MR) are often gravely ill with…

Severe headaches – Understanding Trigeminal Autonomic Cephalgias – types, pathophysiology, treatment
Understand trigeminal autonomic cephalgias (TACs), a group of severe primary headaches that include cluster headache, paroxysmal hemicrania, and SUNCT/SUNA syndromes. This video explains their pathophysiology, distinguishing features, and current treatment approaches for effective symptom relief.
Microbiology Stains Explained Simply | Gram Stain, Acid-Fast, Capsule & Spore
Learn how staining transforms invisible microbes into diagnostic clues with gram stain and acid-fast techniques — essential for identifying bacteria and guiding treatment. This video breaks down why staining is vital, how the gram stain differentiates gram-positive (purple) from gram-negative (pink) bacteria based on cell wall structure, and why that distinction directly impacts antibiotic selection.…
SIADH (Syndrome of Inappropriate ADH secretion) – mechanism, pathophysiology, treatment
Discover the underlying mechanism and pathophysiology of SIADH, a condition marked by excessive antidiuretic hormone secretion leading to water retention and hyponatremia. This video also explains common causes, clinical features, and treatment strategies for effective management.
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…
