Henoch–Schönlein Purpura (IgA Vasculitis)
Overview Henoch–Schönlein purpura (HSP), now termed IgA vasculitis, is the most common systemic vasculitis in children, characterised by IgA1-dominant immune complex deposition in small vessels, particularly affecting the skin, joints, gastrointestinal tract, and kidneys. It predominantly occurs in children aged 3–10 years, with a slight male predominance, and often follows an upper respiratory tract infection.…
View topic ↗Menopause
Overview The menopause means the final menstrual period – diagnosed retrospectively after one year of amenorrhoea. Cessation occurs due to loss of ovarian function. The “declining oocyte pool” theory states that a newborn girl is born with millions of eggs, most of which die by atresia. The average age of menopause is 50, however this can vary…
View topic ↗Hydatidiform Mole (Molar Pregnancy)
Overview Hydatidiform moles are part of a group of diseases falling under gestational trophoblastic disease. A hydatidiform mole refers to the abnormal growth of trophoblastic cells in the placenta, resulting in edematous placental villi that form hydatidiform structures. It is classified as either partial or complete, causing either abnormal foetal development (resulting in foetal demise)…
View topic ↗Rhinosinusitis
Overview Rhinosinusitis is one of the more prevalent chronic illnesses worldwide, affecting individuals of all ages. It is an inflammatory process that involves the nose and paranasal sinuses. Rhinosinusitis may be acute or chronic. Chronic rhinosinusitis can be subject to acute exacerbations. Rhinitis: Irritation and inflammation of the mucosa lining the nasal cavity Sinusitis: Inflammation…
View topic ↗Acute Diabetes Complication (DKA, HHS, Hypoglycaemia)
Diabetic Ketoacidosis Ketoacidosis: A condition resulting from deficient insulin availability, leading to lipid oxidation and metabolism rather than glucose metabolism. The insulin absence results in free fatty acid (FFA) released from adipose tissue and in unregulated hepatic FFA oxidation and ketogenesis. Type I Diabetes: Autoimmune disease where there is attack of beta cells of the…
View topic ↗Cushing's Disease
Overview Cushing's disease is a ACTH dependent syndrome characterised by excess corticosteroid production from the adrenal glands. It is ACTH dependent because it is triggered by an ACTH-secreting pituitary tumour. Cushing's syndrome is an over arching term to describe hypercortisolaemia dependent of independent of ACTH. Adrenal Cushing's syndrome is different because it is hypercortisolaemia independent…
View topic ↗Acute Coronary Syndrome
Overview Coronary artery obstruction or rupture can result in a variety of ischaemic condition which fall under the term of acute coronary syndrome. This does not include stable angina. Ischaemic heart disease is the leading cause of death world wide. The mortality of myocardial infarction is believed to be 45% with 70% of these deaths…

Nephron reabsorption and secretion – renal physiology
Discover how the kidneys maintain homeostasis through the intricate processes of tubular reabsorption and secretion. This video explains the physiology behind nephron function, including key transport mechanisms and clinical relevance in nephrology.

Understanding COPD – Chronic obstructive pulmonary disease cause, pathophysiology and treatment
COPD explained: learn clear, practical strategies to recognize, diagnose, and manage chronic obstructive pulmonary disease, including COPD symptoms, causes, and treatment options. This video breaks down COPD pathophysiology, primary causes like smoking and environmental exposure, and the two main forms—chronic bronchitis and emphysema—so you understand how airflow limitation and damaged alveoli lead to breathlessness. Watch…

Femoroacetabular Impingement Explained: Groin Pain, Labral Tears, Best Exercises & Surgery
Femoral acetabular impingement (FAI) causes early hip pain and joint damage—learn how to spot, diagnose, and treat CAM and pincer lesions. This clear, practical video explains what FAI is, who’s at risk, and the hallmark symptoms (groin pain, the “C-sign,” pain with flexion/internal rotation, clicking or locking). You’ll learn the pathophysiology behind CAM, pincer, and…
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.
“The notes I make during his videos help me retain everything better.
“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.
Cerebral Aneurysm
Overview Cerebral (Intracranial) aneurysm is a focal dilation of an intracranial artery due to weakness of the arterial wall. It occurs in roughly 1-5% of adults and can lead to permanent disability. The most common type is a saccular “berry” aneurysm. Most common location is anterior communicating artery. Cerebral aneurysms are typically asymptomatic until rupture,…
