Overview Acute pancreatitis is a relatively common condition presenting with severe, acute, constant epigastric pain. Incidence of ~5 per 100,000/year. Acute pancreatitis has a significant mortality. Early complications include acute renal failure, DIC, hypocalcemia and ARDS. Acute Pancreatitis: An inflammatory process in which pancreatic enzymes are activated and cause autodigestion of the gland. Chronic Pancreatitis:…

Overview MCTD is a systemic autoimmune rheumatic disease characterized by overlapping clinical features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), polymyositis, with rheumatoid arthritis with high titres of anti-U1 RNP antibodies. It typically affects women aged 20–40 years. Prevalence is estimated at 3.8 per 100,000; more common in females (F:M ~9:1). The disease course…
View topic ↗Endometrial Cancer
Overview Endometrial carcinoma is an epithelial malignancy of the uterine corpus mucosa, usually an adenocarcinoma. Endometrial carcinoma is the most common female genital tract malignancy. Postmenopausal bleeding always needs to be investigated because it can indicate malignant disorders and premalignant conditions, such as endometrial hyperplasia. The most common etiology of postmenopausal bleeding is atrophic endometritis or vaginitis. Menopause:…
View topic ↗Sjögren’s Syndrome
Overview Sjögren’s Syndrome is a chronic, systemic autoimmune disorder characterized by lymphocytic infiltration and destruction of exocrine glands, primarily affecting the salivary and lacrimal glands, leading to dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca). It commonly affects middle-aged women, with a female:male ratio of approximately 9:1. It can be primary (isolated) or secondary (associated…
View topic ↗Diabetes Mellitus Type II
Overview Diabetes Mellitus type II is a progressive disorder defined by deficits in insulin secretion and action (insulin resistance). 1 in 12 people have diabetes (50% do not know they have it). Diabetes type II accounts for over 90% of all diabetes cases. The remaining 10% include type I diabetes. People with type II diabetes…

Pharmacology – Parkinson's Disease
This video provides a concise overview of Parkinson’s disease pharmacology, including key drug classes like levodopa, dopamine agonists, MAO-B inhibitors, and anticholinergics. Understand their mechanisms of action, clinical uses, and side effects in managing motor and non-motor symptoms of Parkinson’s disease.
Physics Revision – Trigonometery II
Strengthen your understanding of trigonometry in physics with this video covering advanced applications like vector resolution, angle calculations, and wave analysis. Ideal for exam prep, this lesson reinforces how sine, cosine, and tangent are used to solve real-world physics problems.
Burping in Babies – Why It Matters, Why it happens, How to Do It
Burping is an essential part of newborn care, helping babies release air swallowed during feeding. In this video, we explain why burping is important, demonstrate effective burping techniques for newborns and older babies, and discuss how often to burp during feeding. We also cover common concerns such as what to do if your baby won’t…
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…
