Methotrexate – Pharmacology (DMARDs, mechanism of action, side effects)
Learn about methotrexate, a key disease-modifying antirheumatic drug (DMARD) used to treat autoimmune conditions and certain cancers. This video explains its mechanism of action, pharmacologic properties, and common side effects such as liver toxicity and bone marrow suppression.
Urinary tract infection overview
Learn about urinary tract infections (UTIs), including their common signs and symptoms, underlying pathophysiology, causes, and treatment strategies. This video provides a clear clinical overview to aid in diagnosis and management of both lower and upper UTIs.
Dactylitis (Sausage Digit) Explained Causes, Symptoms & Associations
An examination of dactylitis as a clinical manifestation of spondyloarthropathies, focusing on the involvement of flexor tendon sheaths, joints, and surrounding soft tissues. The analysis covers the diagnostic criteria to differentiate between inflammatory conditions like psoriatic arthritis, infectious causes such as pyogenic tenosynovitis, crystal-induced arthritis, trauma, sarcoidosis, and sickle cell-related hand-foot syndrome.
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…
