Allergic Rhinitis
Overview Allergic rhinitis is an immunoglobulin E-mediated inflammatory disorder of the nasal mucosa caused by exposure to an aeroallergen. It typically presents with sneezing, nasal itching, clear rhinorrhoea and nasal obstruction , often accompanied by allergic conjunctivitis. 1 Allergic rhinitis is the most common allergic disorder in Australia and New Zealand. In the 2022–2023 Australian…

Piriformis Syndrome
Overview Piriformis syndrome describes buttock pain attributed to irritation or entrapment of the sciatic nerve near the piriformis muscle. Pain may radiate down the back of the thigh and resemble lumbar sciatica. Prolonged sitting often aggravates symptoms. Diagnosis can be difficult because buttock and leg pain have several possible causes and there is no single…

Brain Herniation
Overview Brain herniation is the pathological displacement of brain tissue across rigid intracranial structures, such as the falx cerebri or tentorium cerebelli, or through an opening such as the foramen magnum. It develops when a pressure gradient forces tissue from one intracranial compartment into another. 1 Herniation may compress the brainstem, cranial nerves and cerebral…

Pulmonary Embolism
Overview Pulmonary embolism occurs most often from a dislodged thrombus from the lower limb (DVT). The embolus travels towards the lung and becomes lodged in the pulmonary artery resulting in infarction of the lung tissue. Pulmonary Embolism: Deep Vein Thrombosis (DVT): Blood clot in the deep venous system that usually affects the lower extremities or…

Interstitial Lung Disease
Overview Interstitial Lung Disease is also known as Diffuse Parenchymal Lung Disease (DPLD). A Heterogeneous collection of restrictive lung conditions (>100) that primarily (or at least initially) disrupt the pulmonary interstitium. Interstitial Lung Disease (ILD) are grouped together as they share similar pathophysiological mechanisms, clinical features and radiological findings. Pulmonary Interstitium: Intervening structural tissue between the alveoli space and pulmonary…

Carotid Artery Disease
Overview Carotid artery disease refers to atherosclerotic narrowing of the carotid artery lumen. It is associated with approximately 10-15% of all ischaemic strokes. Stroke is the third leading cause of death and a principal cause of long-term disability in much of the industrialised world. The degree of internal carotid artery stenosis is the most important…

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…

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…
Chronic Obstructive Pulmonary Disease Overview (types, pathology, treatment)
This video provides a clear overview of Chronic Obstructive Pulmonary Disease (COPD), detailing its types, underlying pathology, and current treatment options. Learn how chronic inflammation and airway obstruction lead to symptoms and how management improves patient outcomes.
Antibody somatic (VDJ) recombination – Mechanism
Explore the process of somatic V(D)J recombination in antibody production, a key mechanism behind B cell diversity and adaptive immunity. This educational immunology video breaks down the roles of gene segments, recombinase enzymes, and checkpoints—crucial for understanding immune specificity and medical exam topics.
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…
