View topic ↗Common Variable Immunodeficiency
Overview Common Variable Immunodeficiency (CVID) is the most frequent clinically significant primary antibody deficiency, characterised by hypogammaglobulinaemia and impaired antibody responses. It typically presents with recurrent bacterial infections, autoimmunity, granulomatous disease, and an increased risk of malignancy. CVID affects both sexes equally, with a prevalence of ~1 in 25,000–50,000 individuals. Diagnosis is often delayed, with…

Good places to begin
Explanations learners return to.
Immunology – MHC I Processing
Explore how MHC I molecules present intracellular antigens to cytotoxic T cells, a crucial step in immune surveillance against infected or abnormal cells. This video explains the antigen processing pathway, including proteasome degradation, peptide transport via TAP, and MHC I loading in the endoplasmic reticulum.
Pulmonary Embolism – Overview
Learn about pulmonary embolism, a life-threatening condition caused by a blood clot blocking arteries in the lungs. This video explains its pathophysiology, risk factors, clinical signs, diagnostic approach, and treatment options for prompt and effective management.
Monkeypox virus overview
Learn about the Monkeypox virus, a zoonotic infection related to smallpox that causes fever, rash, and lymphadenopathy. This video explains its transmission, symptoms, clinical course, and current strategies for diagnosis, prevention, and treatment.
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.
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…
