Pseudogout: Calcium Pyrophosphate Deposition Disease
Overview Pseudogout, more accurately known as calcium pyrophosphate deposition disease (CPPD), is a crystal arthropathy characterized by the deposition of calcium pyrophosphate dihydrate crystals in articular cartilage and soft tissues, leading to joint inflammation. It most commonly affects elderly individuals, especially over the age of 60, with a slight female predominance. Clinically, it often mimics…

Myelofibrosis
Overview Myelofibrosis is a type of myeloproliferative diseasecharacterized by clonal myeloid expansion, followed by progressive fibrous connective tissue deposition in the bone marrow, resulting in bone marrow failure. Clonal evolution can also occur, with an increased risk of transformation to acute myeloid leukemia. In addition, disabling constitutional symptoms secondary to the high circulating levels of…

Melanoma
Overview Melanoma accounts for 4 percent of all dermatological cancer. Melanoma has the highest mortality rate of all dermatological cancers, only 14 percent of patients with metastatic melanoma survive for five years. Melanoma is one of the most common cancers in young adults. Melanoma Overview Anatomy & Physiology The skin consist of three layers, from superficial…

Temporal Arteritis (Giant Cell Arteritis)
Overview Giant cell arteritis (GCA), also known as temporal arteritis or cranial arteritis, is the most common systemic vasculitis in adults. It is a granulomatous panarteritis that selectively targets medium and large-sized arteries, displaying a strong tropism for the branches of the external carotid artery (particularly the superficial temporal artery) and the aorta. The disease…

Hodgkins Lymphoma
Overview Hodgkin lymphoma (HL) arises from germinal center or post-germinal center B cells. HL has a unique cellular composition, containing a minority of neoplastic cells ( Reed-Sternberg cells and their variants) in an inflammatory background. Reed-Sternberg cell is a characteristic feature of HL. Epidemiology Lymphoma is divided into Hodgkins and Non-Hodgkins Hodgkins lymphoma accounts for…

Hypercholesterolaemia
Overview Higher levels of cholesterol associated with worse CV outcomes. Three main types that are measured: VLDL, LDL and HDL. High LDL is associated with a significant increase in cardiovascular problems. Hypercholesterolaemia can also run in families. Lifestyle modification aim to reduce cardiovascular risk. Pharmacological agents are lipid lowering drugs, statins being first-line. Lipid Physiology…

Good places to begin
Explanations learners return to.
Liver Cirrhosis
Understand liver cirrhosis, its progression from chronic liver injury to fibrosis, and how it affects overall liver function. This video covers common causes, clinical features, complications, and the impact of cirrhosis on systemic health.
Rett Syndrome
G Protein Signalling
Understand the fundamentals of G protein signaling, including the activation of G protein-coupled receptors (GPCRs), second messenger pathways, and downstream cellular effects. This educational video breaks down key steps and clinical relevance, essential for mastering cell signaling and pharmacology.
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.
Allergic Conjunctivitis
Overview Allergic conjunctivitis is inflammation of the conjunctiva caused by hypersensitivity to an allergen. It usually presents with bilateral ocular itching, redness, watering and conjunctival swelling , often alongside allergic rhinitis, asthma or atopic dermatitis. 1,2 Seasonal and perennial allergic conjunctivitis are common and generally do not threaten vision. Vernal keratoconjunctivitis and atopic keratoconjunctivitis are…
