Paracetamol Overdose
Overview Paracetamol overdose is a common cause of hospital presentation. Paracetamol is an analgesic and antipyretic drug used in both children and adults. Its mechanism of action is yet to be fully determined, and is likely to involve a number of pain pathways. When taken in excess it can cause signs such as vomiting, right…

Umbilical Hernia
Overview Umbilical hernias are one of the most common surgical conditions in infants and children. In infantile umbilical hernia there is a pathological failure of obliteration of umbilical defect. Umbilical hernia can also occur in adults and is usually acquired due to increased intrabdominal pressure due to obesity, pregnancy, ascites. Management is surgery. Hernia: A bulge or protrusion of…

Liver Cirrhosis Complications
Portal Hypertension Overview Normal portal vein pressure is 5–10mmHg. Portal hypertension develops when the portal pressure is greater than 12mmHg. Mechanism of disease Increased Intrahepatic resistance of blood flow through the liver due to cirrhosis Increased splanchnic blood flow secondary to vasodilation leading to increased portal flow through liver Cirrhosis is the most common…

COPD
Overview The diagnosis of COPD is usually limited to individuals who have chronic airflow obstruction associated with tobacco smoke or some other noxious inhalant, and it is usually not difficult to distinguish it from other causes of chronic airflow obstruction. The most commonly associated clinical disorders associated with COPD are emphysema and chronic bronchitis. Chronic…

Leukocyte Adhesion Deficiency
Overview Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency characterised by recurrent bacterial and fungal infections, impaired wound healing, and absence of pus formation due to defective leukocyte adhesion and migration. It results from genetic defects in leukocyte integrins or signalling pathways, preventing neutrophil extravasation from blood vessels into tissues. LAD has an estimated…

Chronic Intestinal Ischaemia
Overview Chronic intestinal ischaemia, more commonly called chronic mesenteric ischaemia , results from an inadequate increase in intestinal blood flow after eating. It is usually caused by atherosclerotic narrowing of one or more mesenteric arteries. Patients classically develop recurrent postprandial abdominal pain, leading to reduced food intake, fear of eating and progressive weight loss. Diagnosis…

Inflammatory SI Joint Pain (Sacroiliitis) vs Mechanical: Key Clues
Discover how to recognize sacroiliitis, its causes, imaging signs, and key mimics to improve diagnosis and patient care. In this video we define sacroiliitis, explain primary causes like axial spondyloarthritis (including ankylosing spondylitis), psoriatic arthritis, IBD-related spondyloarthritis, and reactive arthritis, and show how inflammatory back pain presents (insidious onset, night pain, morning stiffness, improves with…
Immunology – Innate Immunity (Inflammatory Response)
Explore the Innate Immune System and Inflammatory Response in this immunology video, covering first-line defenses, key immune cells, and cytokine signaling. Learn how the body mounts a rapid response to infection—essential knowledge for exams and clinical foundations.
The Human Vertebra (Spine and Backbone)
Discover the anatomy and function of the vertebral column — cervical, thoracic, lumbar, sacral, and coccygeal vertebrae explained with clinical insights. This concise video breaks down the spine’s 33 vertebrae, core structures (vertebral body, arch, foramen, processes), intervertebral discs (annulus fibrosus and nucleus pulposus), and major ligaments that stabilize and protect the spinal cord. You’ll…
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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
