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 ↗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 ↗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 ↗Anklylosing Spondylitis (AS)
Overview Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis that primarily affects the axial skeleton, especially the sacroiliac joints and spine. It is a subtype of the seronegative spondyloarthropathies and is characterised by inflammatory back pain, morning stiffness, and eventual spinal fusion in severe cases. AS often presents in young adults, typically males, and…

Overview Urinary incontinence is an important condition because it causes significant distress. Approximately 15% of the general female adult population have a significant problem with urinary incontinence. Urinary incontinence: Defined as the condition in which there is invontary loss of urine, which can be objectively demonstrated and which is a social or hygienic problem. Stress…

Overview Colon cancer is the second most commonly diagnosed cancer. 1/12 people will develop bowel cancer before the age of 85. However, there are Survival rates are increasing. Early bowel cancer is cured by surgery alone (screening is important!!). If untreated, or diagnosed when distance metastases are present, >98% pf patients die in <5 years. Polyps: …
View topic ↗Interstitial Lung Disease
Overview Interstitial Lung Disease is also known as Diffuse Parenchymal Lung Disease (DPLD). A Heterogeneous collection of restrictive lung conditions (>100) that primarily (or at least initially) disrupt the pulmonary interstitium. Interstitial Lung Disease (ILD) are grouped together as they share similar pathophysiological mechanisms, clinical features and radiological findings. Pulmonary Interstitium: Intervening structural tissue between the alveoli space and pulmonary…

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.

Introduction to Direct and Indirect Inguinal Hernia
Learn the key anatomical differences between direct and indirect inguinal hernias, including their causes and clinical significance. This video breaks down the inguinal canal structure and guides you through diagnosis and management approaches.

Epstein Barr Virus and Infectious Mononucleosis (pathophysiology, investigations and treatment)
Learn how Epstein-Barr Virus (EBV) causes infectious mononucleosis, including its transmission, pathophysiology, and typical clinical presentation. This video covers diagnostic tests, such as the Monospot and serology, along with management strategies and potential complications.

Transcription and Translation Overview
Explore the fundamental processes of transcription and translation, where genetic information is converted from DNA to RNA and then into proteins. This video breaks down each step, highlighting the roles of mRNA, tRNA, ribosomes, and key enzymes in gene expression.
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…
