Meniscal Tear
Overview Medial and lateral knee joint menisci serve to transfer load and absorb shock, aid joint stability and provide lubrication. The meniscus is the most commonly injured structure in the knee joint. Acute tears occurs after axial loading combined with rotation. People may complain of a sensation of clicking or catching of the knee with…

Acute Exacerbation of COPD
Overview An acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is an acute worsening of dyspnoea and/or cough and sputum over fewer than 14 days, often associated with increased airway inflammation triggered by infection, pollution or another insult. 1 It represents a clinically important change from the patient’s usual day-to-day variation and may require additional…

Critical Limb Ischaemia
Overview Critical limb ischaemia (CLI) represents grade III and IV chronic limb ischaemia (based on the Fontaine classification). It presents with rest pain, breakdown of skin and inability to heal an injury, which can lead to infection or gangrene. If left untreated it may be necessary to amputate the affected limb. CLI develops in 1%…

Viral Encephalitis
Overview Viral encephalitis is an acute, life-threatening inflammatory condition of the brain parenchyma caused by direct viral invasion or secondary immune-mediated mechanisms. It represents a neurological emergency associated with high rates of mortality and long-term neurodevelopmental or cognitive sequelae if treatment is delayed. Infectious encephalitis is distinct from aseptic viral meningitis; while meningitis is confined…

Ectopic Pregnancy – Overview (pathophysiology, signs and symptoms, treatment, investigations)
Discover the key features of ectopic pregnancy, where a fertilized egg implants outside the uterus, most commonly in the fallopian tube. This video covers the pathophysiology, clinical signs, diagnostic methods, and treatment options for this life-threatening condition.
Laser
Learn how lasers work by exploring the principles of light amplification, stimulated emission, and energy transitions in atoms. This video explains the basic components, types, and applications of lasers in science and technology. My understanding of Laser from studying Medical Physics Please Comment and provide feedback:)
Fed State
Explore the metabolic changes that occur in the fed state, when the body shifts to storing and utilizing nutrients after a meal. This video explains how insulin regulates glucose uptake, glycogenesis, lipogenesis, and protein synthesis across key organs.
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.
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…
