Benign Prostatic Hyperplasia
Overview Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate gland. There is an increase in stromal and glandular components. Anatomy The prostate is an male organ that sits inferior to the bladder and surrounds the first part of the urethra. It is oval shaped and approximately 4cm thick. The prostate gland is…

Paediatric Orthopaedics Overview
Biology of the Immature Skeleton Physis (Growth Plate): Cartilaginous zone of longitudinal growth. Most susceptible to shear and tension forces (specifically the hypertrophic zone). Damage carries a high risk of growth arrest, limb-length discrepancy, or progressive angular deformity. Periosteum: Thick, metabolically active, and mechanically resilient. Limits fracture displacement, provides an intact hinge for closed reduction,…

Psoriatic Arthritis
Overview Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory arthritis associated with psoriasis, affecting up to 30% of patients with skin psoriasis. It commonly presents in adults aged 30–50 years, with equal gender distribution. The disease is highly variable, involving peripheral joints, axial skeleton, entheses, and skin/nails. Delay in diagnosis is common and can result…

Chronic Kidney Disease
Overview CKD is responsible for a substantial burden of illness and premature death. The kidneys are basically not working as good. Always assume a ↓ eGFR represents acute kidney injury until proven otherwise. Acute Kidney Injury: Rapid reduction in kidney function over hours to days, as measured by serum urea and creatinine and leading to a…

Acute Liver (Hepatic) Failure
Overview Acute liver failure (ALF) is a rare, rapidly evolving syndrome of severe hepatocellular injury with loss of hepatic function. Patients can deteriorate from apparently mild illness to encephalopathy and multiorgan failure within days. Prompt recognition, cause-specific treatment and early transplant-centre involvement are essential. These notes describe adult ALF; paediatric diagnostic criteria differ. [1–4] Acute…

Fungal Pneumonia
Overview Fungal pneumonia refers to infection of the lung parenchyma caused by pathogenic fungi. It is not a single disease: presentation, diagnostic testing and treatment depend on the organism, the patient’s immune status, underlying lung disease, and environmental or geographic exposure. Endemic fungal pneumonias such as histoplasmosis, coccidioidomycosis and blastomycosis may occur in otherwise healthy…

Cervical Stinger/Burner Injuries
Overview A cervical stinger or burner is a transient peripheral nerve injury caused by traction, compression or direct trauma to a cervical nerve root or the upper brachial plexus. It typically occurs during collision or contact sport and produces sudden unilateral burning, stinging or electric-shock pain radiating from the neck or shoulder into the arm.…

Good places to begin
Explanations learners return to.
Cancer – Introduction I
Learn the basics of cancer, including how normal cells transform into malignant ones through genetic mutations and disrupted cell regulation. This video introduces key concepts such as tumor formation, oncogenes, tumor suppressor genes, and the hallmarks of cancer.
Cell Membrane II – Types of Lipid Membranes
Discover the different classes of lipids that make up the cell membrane and how they contribute to its structure and function. This video also explores key evidence supporting the fluid mosaic model and provides a sense of the membrane’s scale and dynamic nature.
Thoracic Outlet Obstruction Explained | Causes, Symptoms, Tests & Treatment
Thoracic Outlet Obstruction (TOS) is caused by nerve or vessel compression near the collarbone. Learn the key types—neurogenic, venous, and arterial—along with symptoms, anatomy, tests (Adson’s, Roos), and treatment. This video is ideal for medical students, physios, and clinicians looking to master upper limb compression syndromes.
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…
