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…

Neonatal Respiratory Distress Syndrome
Overview Neonatal respiratory distress syndrome (RDS) , previously called hyaline membrane disease, is a disorder caused primarily by pulmonary surfactant deficiency and structural lung immaturity. It occurs mainly in premature infants and presents shortly after birth with tachypnoea, grunting, chest recession and increasing oxygen requirements. Severity increases as gestational age decreases. Neonatal RDS is different…

Chronic Pancreatitis
Overview Chronic pancreatitis is a progressive fibro-inflammatory disease of the pancreas that causes irreversible structural damage and eventual loss of exocrine and endocrine pancreatic function. It commonly presents with recurrent or persistent upper abdominal pain and may later cause malabsorption, weight loss and pancreatogenic diabetes. Alcohol exposure and smoking are important causes and accelerators, but…

Eosinophilic Granulomatosis with Polyangiitis
Overview EGPA (formerly Churg-Strauss syndrome) is a rare, small-to-medium vessel necrotizing vasculitis characterized by asthma, eosinophilia, and extravascular granulomas. It commonly affects the lungs, skin, peripheral nerves, and heart. Annual incidence: ~1–3 per million; peak onset in 40s–60s; no significant gender bias. Strongly associated with MPO-ANCA positivity in ~40–60% of patients; others are ANCA-negative. Eosinophilia…

Non-Febrile Seizures (Epilepsy)
This section will mainly focus on Paediatric Epilepsy (NOT FEBRILE SEIZURES) Children and Adults can have seizures because of metabolic disturbances, trauma or being in a febrile state. This does mean they have epilepsy. Epilepsy is a condition characterised by the tendency for recurrent seizures. Presents when at least 2 unprovoked seizures occur >24 hours apart. Overview…

Lung Cancer
Overview Lung cancer is a malignant tumour arising from cells within the lungs or bronchi. Two main groups: Non-small cell lung cancer (NSCLC): approximately 85% Adenocarcinoma Squamous cell carcinoma Large-cell carcinoma Small cell lung cancer (SCLC): approximately 15% More aggressive, with early nodal and distant metastasis . Lung cancer is the leading cause of cancer…

Cushing's Disease
Overview Cushing's syndrome is an over arching term to describe hypercortisolaemia dependent of independent of ACTH. Cushing's disease is a ACTH dependent syndrome characterised by excess corticosteroid production from the adrenal glands. It is ACTH dependent because it is triggered by an ACTH-secreting pituitary tumour. Adrenal Cushing's syndrome is different because it is hypercortisolaemia independent…

Understanding Ear Pain – Otalgia (Innervation of ear, mechanism of ear pain and causes)
Understand the causes of ear pain (otalgia) through an overview of ear anatomy, innervation, and referred pain mechanisms. This video explains how different structures contribute to otalgia and reviews both primary and secondary causes.
Plantar Fasciitis (Plantar Heel Pain): Causes, Diagnosis, Exercises & Evidence-Based Treatment
Relieve heel pain fast: learn what plantar fasciitis is, why it hurts, and proven treatments to get you walking pain-free. Plantar fasciitis, a common cause of sharp heel and arch pain, stems from repetitive strain and microtears in the plantar fascia—the fibrous band that supports your foot arch. In this video you’ll learn clear symptoms…
Carbapenem Antibiotics – Meropenem, Imipenem, Ertapenem
Explore the carbapenem class of antibiotics, including Meropenem, Imipenem, and Ertapenem, known for their broad-spectrum activity against resistant bacteria. This video explains their mechanisms of action, clinical uses, and key differences in spectrum, pharmacokinetics, and side effects.
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…
