Juvenile Idiopathic Arthritis (JIA)
Overview Juvenile Idiopathic Arthritis (JIA) is an umbrella term encompassing a heterogeneous group of chronic inflammatory arthritides of unknown etiology presenting in children under 16 years of age. It represents the most common chronic pediatric rheumatic disease, with an estimated prevalence of 1 in 1,000 children. To meet the diagnostic criteria, arthritis must persist for…

Mitral Stenosis
Overview Mitral stenosis causes an obstruction to blood flow from the left atrium to left ventricle usually as a result of rheumatic heart disease. The stenosis results in increased pressure in the left atrium, pulmonary vasculature and right side of heart. Mitral valve disease is a frequent cause of heart failure and death. Mitral valve area:…

Alcoholic Cardiomyopathy
Overview Alcoholic cardiomyopathy, increasingly termed alcohol-induced cardiomyopathy , is an acquired form of dilated cardiomyopathy caused by prolonged heavy alcohol exposure in the absence of another sufficient cause. It typically produces left ventricular dilatation and systolic dysfunction, leading to heart failure, arrhythmias, thromboembolism and sudden cardiac death. 1,2 The commonly used exposure threshold is more…

Antiphospholipid Syndrome (APS)
Overview Antiphospholipid Syndrome (APS) is an acquired autoimmune thrombophilia characterized by recurrent venous or arterial thromboses and/or pregnancy morbidity in the presence of persistent antiphospholipid antibodies (aPL). APS may occur as a primary condition or secondary to systemic lupus erythematosus (SLE). Prevalence of aPL in the general population is ~2%, but true APS is rare…

Chronic Spontaneous Urticaria +/- angioedema
Overview Chronic spontaneous urticaria (CSU) is a mast-cell–driven skin disorder defined by recurrent wheals (hives), angioedema, or both for >6 weeks without a specific external trigger , with a point prevalence around 0.5–1% and a female predominance; median disease duration is ~2–5 years, but a subset persists longer and markedly impairs quality of life and…

Systemic Sclerosis-Associated Interstitial Lung Disease
Overview Systemic sclerosis–associated interstitial lung disease (SSc-ILD) is one of the most common and severe internal organ manifestations of systemic sclerosis (SSc), occurring in up to 50–60% of patients on HRCT, with clinically significant disease in ~25–30%. It is a major cause of SSc-related mortality. The most frequent histopathological pattern is nonspecific interstitial pneumonia (NSIP),…

Videos
Hand-drawn explanations that build the big picture as the concept unfolds.
Notes
Clear written explanations for review, reference and filling in the details.
Diagrams
Visual snapshots that help you easily review topics.
Questions
Test whether the explanation stayed with you—not just whether it looked familiar.
Good places to begin
Explanations learners return to.
Salivary glands – Anatomy and Physiology
Learn the anatomy and physiology of the major salivary glands, including the parotid, submandibular, and sublingual glands. This video covers their structure, secretion pathways, and role in digestion and oral health.
Bacterial Vaginosis
Learn about bacterial vaginosis, a common vaginal condition caused by an imbalance in the normal bacterial flora. This video explains its symptoms, underlying microbiology, risk factors, diagnostic methods, and available treatments.
Global Hands – Social Determinants of Health
Explore the social determinants of health and how factors like income, education, environment, and access to care shape health outcomes globally. This video highlights the importance of equity and policy in addressing health disparities across populations.
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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
