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…

Hyperemesis Gravidarum
Overview Hyperemesis gravidarum (HG) exists on a spectrum of nausea and vomiting in pregnancy (NVP). NVP refers to symptoms of nausea, vomiting or dry retching commencing in the first trimester, with no other cause identified. 1 HG refers to severe, persistent vomiting that may result in malnutrition, dehydration, weight loss and debility due to illness.…

RA Related Pleural Effusion
Overview Rheumatoid pleural effusion (RPE) is an uncommon extra‑articular manifestation of rheumatoid arthritis (RA), occurring in ~2–5% of patients, more often in middle‑aged men with high rheumatoid factor (RF) titres, despite RA being more common in women. It typically presents during active disease or in patients with rheumatoid nodules, but can occasionally precede joint symptoms.…

Sexual Transmitted Infection
Overview Sexually transmitted infections (STI) are a significant public health worldwide. STI can result in chronic disease, pregnancy complications, infertility, and even death. Globally, congenital syphilis is still a leading cause of stillbirth and neonatal death. Antibiotic-resistant Neisseria gonorrhoeae continues to be a significant public health concern. Chlamydia trachomatis infection is the most frequently reported…

Cardiogenic Shock
Overview Cardiogenic shock is a life-threatening clinical syndrome in which cardiac dysfunction causes inadequate cardiac output and tissue hypoperfusion. Hypotension is common but is not essential; patients may initially maintain blood pressure through marked vasoconstriction while organ perfusion deteriorates. 1 Acute myocardial infarction is a major cause, but cardiogenic shock may also complicate acute or…

Lateral and Medial Elbow Tendinopathy (Epicondylitis)
Overview Medial and lateral elbow tendinopathies are common overuse injuries affecting the common flexor and extensor tendon origins at the elbow, respectively. Commonly known as Golfer's Elbow (medial) and Tennis Elbow (lateral), these conditions are primarily degenerative (tendinosis) rather than inflammatory (tendinitis), resulting from repetitive microtrauma and failed healing responses. Lateral Elbow Tendinopathy (Tennis Elbow…

Good places to begin
Explanations learners return to.
Fasted State
Learn how the body adapts during the fasted state by shifting to energy mobilization and conservation. This video explains the roles of glucagon and other hormones in promoting glycogenolysis, gluconeogenesis, and lipolysis to maintain blood glucose levels.
Pharmacology – Diuretics
Understand how diuretics work to promote fluid loss by targeting different parts of the nephron and altering electrolyte reabsorption. This video covers the main classes of diuretics, their mechanisms, clinical uses, and potential side effects.
Red blood cell life cycle – erythropoiesis mechanism
Learn about the life cycle of red blood cells, from their production in the bone marrow to their removal by the spleen. This video explains the stages of erythropoiesis, the role of erythropoietin, and how aging RBCs are broken down and recycled.
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.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
