Gastric Antral Vascular Ectasia (GAVE)
Overview Gastric antral vascular ectasia (GAVE, “watermelon stomach”) is a rare but important cause of non-variceal upper gastrointestinal bleeding, often presenting with chronic iron-deficiency anaemia or recurrent overt bleeding in older adults, particularly women [1–4]. It is frequently associated with systemic conditions such as liver cirrhosis (~30% of cases) and autoimmune/connective-tissue disease (especially systemic sclerosis).…
View topic ↗Anaphylaxis
Overview Anaphylaxis is a severe, systemic hypersensitivity reaction that is rapid in onset and potentially fatal, most often triggered by foods, medications, or venom; global incidence is ~50–112 per 100,000 person-years with rising emergency presentations in many regions, including Australia [1,2,4] . Mortality is low but non-trivial and is driven by airway obstruction, severe bronchospasm,…
View topic ↗Non-Febrile Seizures (Epilepsy)
This section will mainly focus on Paediatric Epilepsy (NOT FEBRILE SEIZURES) Children and Adults can have seizures because of metabolic disturbances, trauma or being in a febrile state. This does mean they have epilepsy. Epilepsy is a condition characterised by the tendency for recurrent seizures. Presents when at least 2 unprovoked seizures occur >24 hours apart. Overview…
View topic ↗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 ↗Cryoglobulinaemic Vasculitis
Overview Cryoglobulinaemic vasculitis is an immune complex–mediated small to medium vessel vasculitis caused by circulating cryoglobulins—immunoglobulins that precipitate below 37 °C and redissolve on warming. These immune complexes deposit in vessel walls, activate complement (typically with marked C4 consumption), and drive leukocytoclastic vasculitis. “Mixed” CV (types II and III) is most often linked to hepatitis…
View topic ↗Liver Mass I Tumour
Author Armando Faigl MBBS Areej zeeshan Overview Liver tumors are divided into Benign and Malignant. Most liver tumors are benign, asymptomatic and found incidentally on unrelated imaging. Malignant liver tumours are associated with risk factors (Hep C, Cirrhosis) and present with a spectrum of clinical signs and symptoms such as right upper quadrant pain and…
View topic ↗Complex Regional Pain Syndrome (CRPS)
Overview CRPS is a disproportionate, regional pain syndrome of a limb that typically follows injury or surgery and features sensory, vasomotor, sudomotor/oedema, and motor/trophic changes. The prevalence after limb fracture/surgery varies widely (≈1–7% overall, higher in some distal radius cohorts) and early recognition with rehabilitation improves outcome. Important risk factors include fracture (especially wrist/ankle), immobilisation,…

Diverticular Disease (diverticulitis) – Overview
Learn the key aspects of diverticular disease and diverticulitis, including causes, symptoms, and management. This video provides a clear overview to help understand diagnosis and treatment options.

Hypertension – Cardiac – Medications Part I
Describes the mechanism of action of various medications used to treat hypertension and other cardiac complications.

Arrhythmia Overview – Mechanism of bradyarrhythmia and tachyarrhythmia
Explore the fundamentals of cardiac arrhythmias, focusing on the mechanisms behind bradyarrhythmias (slow heart rhythms) and tachyarrhythmias (fast heart rhythms). This video breaks down the electrical disturbances, conduction system abnormalities, and common causes that lead to rhythm disorders.
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.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
