Sjögren’s-Associated Interstitial Lung Disease
Overview Sjögren’s-associated interstitial lung disease (Sjögren’s-ILD) is a significant extra-glandular manifestation of primary Sjögren’s disease (pSS), occurring in ~9–20% of patients clinically, with subclinical involvement detectable in up to 50% on HRCT. It may precede sicca symptoms or develop late in the disease course. The most common ILD pattern is nonspecific interstitial pneumonia (NSIP), followed…
View topic ↗Otitis Externa
Overview Acute otitis externa (AOE) is a common ear condition seen in the primary health care setting. Also known as ‘swimmer’s ear’ or ‘tropical ear’, it is prevalent in hot humid climates. AOE is an inflammatory condition of the ear canal skin. The causes are infective or non-infective. Otitis externa: Inflammation of the outer ear…
View topic ↗Cystic Fibrosis
Overview Cystic fibrosis causes the dehydration of the mucus lumen causing thick sticky mucus to build up. This occurs mainly the lungs, causing productive cough and increasing rates in respiratory infections, and the pancreas causing pancreatic dysfunction. Cystic fibrosis occurs due to a mutation in the CFTR gene. Salty sweat is also another important characteristic…
View topic ↗Osteomalacia / Rickets
Overview Osteomalacia (adults) and rickets (children) are disorders of impaired bone mineralisation leading to soft, poorly mineralised bone. It arises when there is insufficient calcium–phosphate supply to the mineralising matrix due to vitamin D deficiency, calcium deficiency, phosphate deficiency (often FGF23-mediated). Nutritional rickets still occurs worldwide, while hypophosphataemic forms (e.g., XLH, tumour-induced osteomalacia) are rarer…
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 ↗Urinary Tract Infection (Children)
Overview Urinary Tract infections (UTIs) in children are common and usually carry low risk. UTIs are often non-specific and can not be diagnosed on symptoms alone. A clean specimen (urine) is required for the diagnosis of UTI. Any child who is unwell, and most children under 6 months, should be admitted for IV antibiotics. The…

Good places to begin
Explanations learners return to.
Mitral Regurgitation (incompetence)
Learn the essentials of mitral regurgitation, including its underlying pathophysiology, clinical presentation, and treatment options. This video explains how valve dysfunction leads to backflow of blood, causing symptoms like dyspnea and fatigue, and outlines both medical and surgical interventions.
Hepatorenal Syndrome – causes, pathophysiology and mechanism
Learn about hepatorenal syndrome, a serious complication of advanced liver disease that leads to progressive kidney dysfunction. This video explains the underlying causes, pathophysiology, and mechanisms involving renal vasoconstriction and impaired perfusion despite structurally normal kidneys.
Snapping Hip Syndrome Explained – Causes, Symptoms & Treatment
Snapping hip syndrome (snapping hip, Coxa saltans) causes an audible or palpable snap around the hip during movement and can be painless or lead to pain, bursitis, tendinopathy, or labral damage. This video explains the three main types—external, internal, and intra‑articular—detailing their mechanisms, symptoms, diagnosis, and treatment so viewers can identify causes and choose the…
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.
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…
