Severe Combined Immunodeficiency (SCID)
Overview Severe combined immunodeficiency (SCID) is the most severe form of primary immunodeficiency, characterised by profound defects in both humoral (B-cell) and cellular (T-cell) immunity. It presents in infancy with recurrent, severe, and opportunistic infections, chronic diarrhoea, and failure to thrive. Without curative therapy, most infants die within the first year of life. Incidence is…

Acute Pancreatitis
Overview Acute pancreatitis is sudden inflammation of the pancreas caused by premature activation of pancreatic digestive enzymes within the gland. It ranges from a mild, self-limiting illness to severe necrotising pancreatitis with persistent organ failure. The most common causes are gallstones and alcohol, although hypertriglyceridaemia, medicines, procedures and metabolic disorders are also important. Acute Pancreatitis:…

Buerger’s Disease
Overview Buerger’s disease, also called thromboangiitis obliterans , is a non-atherosclerotic inflammatory and thrombotic disorder affecting small- and medium-sized arteries and veins, predominantly in the distal limbs. It is strongly associated with tobacco exposure and causes progressive digital ischaemia, superficial thrombophlebitis, painful ulcers and gangrene. 1–3 The disease classically affects younger people who smoke and…

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…

Cervical Cancer
Overview Cervical cancer is an HPV-related malignancy of the uterine cervical mucosa. Most cervical tumours contain HPV DNA (99.7%) . There are many variants of HPV, HPV-16 and 18 are the 2 most common high-risk types. Cervical cancer is proceeded by an idenifiable precursor lesion (cervical intraepithelial neoplasia (CIN1)) that may progress to invasive cancer. CIN can…

Aspiration Pneumonia
Overview Aspiration pneumonia is an acute pulmonary infection caused by inhalation of bacteria-rich oropharyngeal or upper gastrointestinal material into the lower respiratory tract. It occurs when aspiration is combined with impaired airway protection, ineffective clearance and sufficient pathogenic bacterial burden. It is particularly important in older adults, people with neurological disease, frailty, dysphagia or reduced…

Hemochromatosis – iron physiology and pathophysiology
Learn how hemochromatosis (iron overload) develops, how to diagnose it, and effective treatments like phlebotomy and iron chelation. This clear, concise video explains iron metabolism, the role of hepcidin and ferroportin, and genetic (HFE) and secondary causes of hemochromatosis so you can recognize risk factors and symptoms early. You’ll learn where iron is stored and…

Explore the fundamentals of Membrane Proteins, including their classification, structure, and functions in transport, signaling, and cell interactions. This video is ideal for mastering the differences between integral and peripheral proteins, with clear explanations and clinically relevant examples.
Physiological Changes in Pregnancy
Learn about the key physiological changes that occur during pregnancy, including cardiovascular, respiratory, and hormonal adaptations. This video provides a concise overview of how the body supports fetal development and prepares for childbirth.
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.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
