Spondylarthropathy
Overview The spondyloarthropathies are a diverse group of inflammatory arthritides that share certain genetic predisposing factors and clinical features. Their most characteristic feature is inflammatory back pain. Enthesitis, another characteristic feature, involves inflammation at sites where tendons, ligaments, or joint capsules attach to bone. Features of Spondylarthropathy Sacroiliac and spinal (axial involvement) Enthesitis at long attachments…

Hyperthyroidism (Thyrotoxicosis)
Overview The most common cause of hyperthyroidism are Graves disease, multinodular goitre, an autonomously functioning thyroid nodule (adenoma) and subacute thyroiditis. Graves Disease is more common in women. Multinodular goitre is more common in the elderly. Graves disease typically manifests in middle aged women. Thyroid diseases are more common in women. Hyperthyroidism: denote conditions in which…

Meniscal Tear
Overview Medial and lateral knee joint menisci serve to transfer load and absorb shock, aid joint stability and provide lubrication. The meniscus is the most commonly injured structure in the knee joint. Acute tears occurs after axial loading combined with rotation. People may complain of a sensation of clicking or catching of the knee with…

Paediatric Orthopaedics Overview
Osteochondroses Osteochondroses is a condition that affects the epiphysis of bones. Pathology consists of localised area of ischaemic bone necrosis and oedema of adjacent soft tissue. Osteochondroses result in avascular necrosis of the epiphyseal bone, similar to Perthes disease, but less common. In general osteochondroses is more troublesome than serious. Age effects usually 10-15 +/-…

Felty Syndrome
Overview Felty syndrome is a rare but serious extra-articular manifestation of long-standing, seropositive rheumatoid arthritis (RA), characterized by the classic triad of RA, splenomegaly, and neutropenia. It was first described in 1924 by the US-American physician Augustus Roi Felty. It most commonly occurs after at least 10 years of poorly controlled RA and is associated…

Explanations learners return to.
Deep Vein Thrombosis – Overview (pathophysiology, treatment, complications)
Discover the pathophysiology behind deep vein thrombosis (DVT), its risk factors, treatment strategies, and potential complications like pulmonary embolism. This video provides a clear overview of how clots form in the deep veins and highlights key diagnostic and therapeutic approaches.
MHC class II processing – antigen presentation mechanism
Learn how MHC II molecules present extracellular antigens to helper T cells, playing a key role in activating adaptive immune responses. This video explains the antigen processing steps, including endocytosis, peptide loading in endosomes, and the involvement of the invariant chain and HLA-DM.
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.
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.
Aortic Aneurysm
Overview An aortic aneurysm is a pathological dilatation of the aorta caused by weakening of the arterial wall. It may involve the aortic root, ascending aorta, arch, descending thoracic aorta, thoracoabdominal aorta or abdominal aorta. Most aortic aneurysms are asymptomatic and are discovered incidentally or through screening. Progressive enlargement increases the risk of rupture, dissection,…
