Complement Deficiencies
Overview Complement deficiencies are rare primary immunodeficiencies resulting from inherited absence or dysfunction of complement proteins, regulators, or receptors. They predispose to recurrent bacterial infections, autoimmune disease (particularly systemic lupus erythematosus–like syndromes), and in some cases angioedema. Complement proteins play a central role in innate immunity by opsonisation, chemotaxis, and direct lysis of pathogens via…

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…

Botulism
Overview Botulism is a rare, life-threatening neuroparalytic syndrome caused by botulinum neurotoxin. It classically produces acute bilateral cranial nerve palsies followed by symmetrical descending flaccid paralysis, which may progress to respiratory failure. 1 Botulism is very rare in Australia, where most reported cases occur in infants younger than 12 months. Nevertheless, foodborne, wound and iatrogenic…

Umbilical and Epigastric Hernia
Overview Umbilical and Epigastric hernias are types of Primary Ventral abdominal wall hernias. Epigastric hernias are two to three times more common in men. Umbilical hernias are three times more likely in females. Most epigastric hernias contain preperitoneal fat, while most umbilical hernias contain omentum or bowel. These hernias are usually asymptomatic unless incarcerated, obstructed…

Paediatric Viral Cutaneous Infection
Classical Exanthem Overview Exanthem refers to the cutaneous manifestation of a viral illness (enanthem is the manifestation in the mouth). Historically, 6 exanthems have been recognised, 4 of which are viral. However, obviously there are much more common exanthems. The six described are: Measles (measles virus) Scarlet fever ( streptococcus pyogenes ) – this is…

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.
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…
