VEXAS Syndrome
Overview VEXAS syndrome is a late-onset, adult autoinflammatory disease caused by acquired somatic mutations in the UBA1 gene, leading to dysregulated innate immunity, systemic inflammation, and overlapping haematologic and rheumatologic manifestations. VEXAS stands for Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic. It predominantly affects older males due to its X-linked nature and typically presents with refractory…

Developmental Hip Dysplasia
Overview Developmental Dyplasia of the hip (DDH) is previously known as congenital dislocation of the hip (however name changed as some of the hip problems develop after birth). Spectrum of condition related to development of the hip in infants and young children. Includes abnormal development of the acetabulum and proximal femur + mechanical instability of the hip joint. Usually involves…

Buerger’s Disease
Overview Buerger’s disease, also called thromboangiitis obliterans , is a non-atherosclerotic inflammatory and thrombotic disorder affecting small- and medium-sized arteries and veins, predominantly in the distal limbs. It is strongly associated with tobacco exposure and causes progressive digital ischaemia, superficial thrombophlebitis, painful ulcers and gangrene. 1–3 The disease classically affects younger people who smoke and…

Atypical Pneumonia
Overview Atypical pneumonia is a clinical term traditionally used for pneumonia caused by organisms that do not have a cell wall, live intracellularly, or are not detected on routine bacterial culture. Important causes include Mycoplasma pneumoniae , Chlamydia pneumoniae , Legionella species, Chlamydia psittaci and Coxiella burnetii . Respiratory viruses can produce a similar syndrome.…

Septic Arthritis
Overview Septic arthritis refers to infection in a joint; it is usually caused by bacteria but can be caused by fungi or mycobacteria. Septic arthritis due to bacterial infection is often a destructive form of acute arthritis. Arthritis: Inflammation of joint Arthrosis: Degeneration of joint Septic Arthritis: Infection of joint Pathophysiology Septic arthritis involves bacterial…

Cervical Radiculopathy
Overview Cervical radiculopathy is dysfunction of a cervical nerve root caused by irritation or compression as it leaves the spine. It commonly produces pain radiating from the neck into one arm, sometimes with paraesthesia, numbness, weakness or altered reflexes. A disc herniation or degenerative narrowing of the neural foramen is a common cause. Diagnosis is…

Prostatitis
Overview Prostatitis refers to a spectrum of conditions involving inflammation of the prostate gland, ranging from acute bacterial infection to chronic pelvic pain syndromes. It is a common urological condition affecting men of all ages, particularly those aged 30–50 years. The National Institutes of Health (NIH) classifies prostatitis into four categories: acute bacterial, chronic bacterial, chronic…

Explanations learners return to.
Understanding Spirometry – Normal, Obstructive vs Restrictive
This video breaks down spirometry, explaining how to interpret normal, obstructive, and restrictive lung patterns for accurate respiratory assessment. Learn key differences and clinical significance essential for diagnosing lung diseases.
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.
Ear Anatomy
Explore Ear Anatomy in this video, covering the outer, middle, and inner ear structures along with their roles in hearing and balance. Perfect for exams and clinical review, this video simplifies complex anatomy with clear visuals and functional insights.
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.
