Gastroenteritis (Infectious Diarrhoea)
Overview Gastroenteritis continues to cause significant morbidity in developed and developing countries. The most common cause are viral and bacterial including: Norovirus Enteric adenoviruses E-coli Salmonella spp. and Shigella spp. Campylobater jejuni Diarrhoea: Loose, water like stools that occur with increased frequency and an increased volume of >200g per day Gastroenteritis: >3 or more loose…

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…

Hydrocephalus
Overview Hydrocephalus is excessive accumulation of CSF in the cerebral ventricles. In children, look for increasing head circumference, increased intracranial pressure, a bulging fontanelle, scalp vein engorgement, and paralysis of upward gaze. The most common causes include: Congenital malformations Tumors Inflammation (i.e hemorrhage, meningitis). Treat the underlying cause, if possible; otherwise a surgical shunt is created…

Scaphoid Fracture
Overview Scaphoid fracture is the most common carpal bone fracture , accounting for ~60–70% of all carpal fractures. It occurs most frequently in young adults (15–40 years) following a fall on the outstretched hand (FOOSH). The scaphoid’s tenuous blood supply predisposes to non-union and avascular necrosis, especially in proximal fractures. Early recognition is essential as…

Mitral Stenosis
Overview Mitral stenosis causes an obstruction to blood flow from the left atrium to left ventricle usually as a result of rheumatic heart disease. The stenosis results in increased pressure in the left atrium, pulmonary vasculature and right side of heart. Mitral valve disease is a frequent cause of heart failure and death. Mitral valve area:…

Acute Cholecystitis
Overview Acute cholecystitis is acute inflammation of the gallbladder, usually caused by a gallstone obstructing the cystic duct. Persistent obstruction causes gallbladder distension, inflammation and possible secondary bacterial infection. Most cases are calculous, while acalculous cholecystitis occurs mainly in critically ill or severely immunocompromised patients. Cholecystectomy: surgical removal of the gallbladder. Calculous cholecystitis: gallbladder inflammation…

Henoch-Schönlein purpura (Spring Fever)
Overview Henoch Schonlein Purpura is a IgA vasculitis characterised by the Tetrad: palpable purpuric petechial rash, abdominal pain, kidney involvement and arthralgia. Aetiology is unknown but thought to have a genetic predisposition. Clinical Manifestation Henoch Schonlein Purpura Tetrad Palpable purpuric petechial rash, abdominal pain, kidney involvement and arthralgia.

Lung Function – Lung Volumes and Capacities
Explore the essential lung volumes and capacities that define respiratory function and health in this detailed video. Understand how these measurements aid in diagnosing and managing pulmonary conditions.
Amebiasis – entamoeba histolytica symptoms, pathophysiology, diagnosis, treatment
Amebiasis is a parasitic infection caused by entamoeba histolytica. Entamoeba histolytica infection is common worldwide and it can affect anyone, although it is more common in people who live in tropical areas with poor sanitary conditions. Several protozoan species in the genus Entamoeba colonize humans, but not all of them are associated with disease. Entamoeba…
The Mitochondria
Discover the structure and function of mitochondria, known as the powerhouse of the cell, and their role in energy production through cellular respiration. This video explains how mitochondria generate ATP, regulate metabolism, and contribute to cell signaling and apoptosis.
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.
Cerebral Aneurysm
Overview Cerebral (Intracranial) aneurysm is a focal dilation of an intracranial artery due to weakness of the arterial wall. It occurs in roughly 1-5% of adults and can lead to permanent disability. The most common type is a saccular “berry” aneurysm. Most common location is anterior communicating artery. Cerebral aneurysms are typically asymptomatic until rupture,…
