Glomerulonephritis
Overview Glomerulonephritis is inflammation of the glomerulus. Glomerulonephritis is classified by clinical syndrome/presentation (e.g. nephritic or nephrotic syndrome), histological appearance , or by aetiology. We will divide glomerulonephritis broadly into two broad types: Nephritic glomerulonephritis and nephrotic glormerulonephritis. Classification Two Types of Glomerular disease: Nephrotic Syndrome Nephritic Syndrome DIFFERENCE BETWEEN NEPHROTIC AND NEPHRITIS SYNDROME …
View topic ↗Caplan Syndrome
Overview Caplan syndrome, also known as rheumatoid pneumoconiosis, is a rare condition seen in patients with rheumatoid arthritis (RA) who have had occupational exposure to inhaled dust, particularly coal dust or silica. It is characterised by multiple, rounded pulmonary nodules and underlying pneumoconiosis. It primarily affects middle-aged male coal workers and is now rare in…
View topic ↗Angina Pectoris
Overview Angina Pectoris refers to the pain caused by myocardial ischaemia. Myocardial Ischaemia is usually caused by stenosis within the vessel decreasing blood flow to the muscle, but it can be caused by tachycardia, anaemia, aortic stenosis, left ventricular hypertophy and many other disease. Angina "latin choking". Angina Pectoris: Pain caused by myocardial ischaemia (not myocardial…

56 year old lady recurrent presentations to your practice for polyuria and increased thirst. Random serum glucose and urinary glucose have returned normal. Patient has otherwise been well, complains of no dysuria, haematuria, fevers or night sweats . Overview Diabetes Insipidus (DI) is associated with inadequate arginine vasopressin (known as antidiuretic hormone) secretion or renal…
View topic ↗Chronic Pancreatitis
Overview Chronic pancreatitis is characterised by recurrent or persistent abdominal pain arising from the pancreas. The inflammatory process results in irreversible destruction and fibrosis of the pancreas. Often associated with exocrine or endocrine pancreatic insufficiency. Acute Pancreatitis: An inflammatory process in which pancreatic enzymes are activated and cause autodigestion of the gland. Chronic Pancreatitis: Irreversible…
View topic ↗Birth Defects
Overview Birth defects are the leading cause of perinatal and post- neonatal deaths, and result in substantial morbidity and disability in developed countries. There is a wide variety of mechanisms including genetic, environmental and multifactorial. Major birth defects affect 2–3% of live-borns, and minor birth defects affect 15%. Preventative strategies remain limited, but include maternal folic acid supplementation,…
View topic ↗Cervical Cancer
Overview Cervical cancer is an HPV-related malignancy of the uterine cervical mucosa. Most cervical tumours contain HPV DNA (99.7%) . There are many variants of HPV, HPV-16 and 18 are the 2 most common high-risk types. Cervical cancer is proceeded by an idenifiable precursor lesion (cervical intraepithelial neoplasia (CIN1)) that may progress to invasive cancer. CIN can…

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.
Liver Cirrhosis (Causes I)
Explore the major causes of liver cirrhosis, including chronic alcohol use, viral hepatitis, and metabolic disorders. This video explains how long-term liver damage leads to fibrosis and disrupts normal liver structure and function.
Bilirubin Metabolism – unconjugated and conjugated bilirubin
Learn how bilirubin is formed and processed in the body, distinguishing between unconjugated and conjugated forms. This video explains the steps of bilirubin metabolism, its transport, hepatic conjugation, and clinical relevance in conditions like jaundice.
Cardiology – Heart Physiology I (Cardiac Myocyte and Membrane Potential)
Explore the physiology of cardiac myocytes, focusing on their electrical properties and how membrane potentials regulate heart contractions. This video explains ion channel activity, resting potential, and the phases of the cardiac action potential in a clear and structured way.
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.

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…
