Eosinophilic Granulomatosis with Polyangiitis
Overview EGPA (formerly Churg-Strauss syndrome) is a rare, small-to-medium vessel necrotizing vasculitis characterized by asthma, eosinophilia, and extravascular granulomas. It commonly affects the lungs, skin, peripheral nerves, and heart. Annual incidence: ~1–3 per million; peak onset in 40s–60s; no significant gender bias. Strongly associated with MPO-ANCA positivity in ~40–60% of patients; others are ANCA-negative. Eosinophilia…

Substance Dependence (Addiction), Withdrawal and Overdose
Overview of addition medicine. This section is a brief introduction to substance abuse, followed by section that look at specific drugs of addiction. Substance Misuse: Consumption above designated low risk levels Substance Abuse: repetitive substance use resulting in social complications (financial, occupational and legal) Substance Tolerance: Defined by either of the following: a need for…

Complement Deficiencies
Overview Complement deficiencies are rare primary immunodeficiencies resulting from inherited absence or dysfunction of complement proteins, regulators, or receptors. They predispose to recurrent bacterial infections, autoimmune disease (particularly systemic lupus erythematosus–like syndromes), and in some cases angioedema. Complement proteins play a central role in innate immunity by opsonisation, chemotaxis, and direct lysis of pathogens via…

Parturition and Routine Care
Overview Parturition Physiology Preterm: defined as babies born alive before 37 weeks of pregnancy are completed. Term: defined as babies born alive after 37 weeks and before 42 weeks Postterm (induced for labour): defined as babies born alive after 42 weeks. Birthweight Low birth weight: <2500g regardless of age Very low birth weight: <1500g regardless of…

Primary Hypothyroidism
Overview Hypothyroidism: Variety of abnormalities that cause insufficient secretion of thyroid hormones. The most common cause is autoimmune thyroid disease Primary Hypothyroidism : Clinical state resulting from underproduction of T4 and T3. Low free T4 with an elevated TSH is diagnostic of primary hypothyroidism. Autoimmune thyroiditis (Hashimoto's disease) is the most common cause of primary hypothyroidism.…

Snapping Hip Syndrome (Coxa Saltans)
Overview Snapping Hip Syndrome (SHS) is characterized by an audible or palpable “snap” around the hip during motion; it may be painless or painful and can be unilateral or bilateral. Prevalence estimates suggest up to ~5–10% of the general population may experience snapping to some degree, with higher rates in dancers and athletes who work…

Acute Liver (Hepatic) Failure
Overview Acute liver failure is a rare but life-threatening critical illness that occurs most often in patients who do not have preexisting liver disease. Acute liver failure is seen most commonly in previously healthy adults in their 30s and presents unique challenges in clinical management. The clinical presentation usually includes hepatic dysfunction, abnormal liver biochemical…

PART I – Pneumonia (Overview, Lobar and Bronchopneumonia)
Learn the essential differences between lobar and bronchopneumonia in this clear overview of pneumonia, including its clinical presentation and basic classification. Understand how inflammation patterns affect lung segments and set the stage for diagnosis and treatment.
Glucocorticoid Induced Osteoporosis and Fractures – mechanism and pathophysiology of fractures
Glucocorticoids are used in many inflammatory, autoimmune conditions. While being used to treat an underlying disease gluocorticoids are associated with an appreciable risk of bone loss and increases risk of fracture, which is most pronounced in the first few months of use. In general risk of fracture increases with age, dose and duration of use.…
Hypersensitivity pneumonitis
Discover hypersensitivity pneumonitis, an immune-mediated lung condition triggered by inhaled environmental antigens. This video explains its pathophysiology, clinical signs, diagnostic approach, and strategies for management including antigen avoidance and medical 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.

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.
Acute Coronary Syndrome: Myocardial infarction (STEMI, NSTEMI)
Overview Acute coronary syndrome (ACS) describes acute myocardial ischaemia caused by an abrupt reduction in coronary blood flow. It includes myocardial infarction (MI) and unstable angina and is a time-critical medical emergency. This article focuses on ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). 1 Myocardial infarction is diagnosed when there is…
