Pulmonary Sarcoidosis
Overview Sarcoidosis is a multisystem granulomatous disease of unknown cause, characterised by the formation of non‑caseating granulomas in affected organs. Pulmonary involvement occurs in ~90% of patients, making it the most common manifestation. Global prevalence varies widely (e.g., 3.7/100,000 in Japan vs. 28.2/100,000 in Finland), with higher rates in Black Americans and Northern Europeans. Peak…

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…

Stroke (Ischaemic and Haemorrhagic)
Overview Third most common cause of death worldwide and most common cause of neurological disability. It is subdivided into ischaemic stroke (caused by vascular occlusion or stenosis) and haemorrhagic stroke (caused by vascular rupture, resulting in intra-parenchymal and/or subarachnoid haemorrhage). Stroke: Acute onset of a focal neurologic deficit due to a cerebral infarction or hemorrhage. Transient Ischaemic…

Felty Syndrome
Overview Felty syndrome is a rare but serious extra-articular manifestation of long-standing, seropositive rheumatoid arthritis (RA), characterized by the classic triad of RA, splenomegaly, and neutropenia. It was first described in 1924 by the US-American physician Augustus Roi Felty. It most commonly occurs after at least 10 years of poorly controlled RA and is associated…

Allergic Conjunctivitis
Overview Allergic conjunctivitis is inflammation of the conjunctiva caused by hypersensitivity to an allergen. It usually presents with bilateral ocular itching, redness, watering and conjunctival swelling , often alongside allergic rhinitis, asthma or atopic dermatitis. 1,2 Seasonal and perennial allergic conjunctivitis are common and generally do not threaten vision. Vernal keratoconjunctivitis and atopic keratoconjunctivitis are…

Community Acquired Pneumonia
Overview Community acquired pneumonia occur in individuals who are not in hospital (or have been in hospital in the past 48 hours) and who are not significantly immunocompromised. The World Health Organization estimates that lower respiratory tract infection is the most common infectious cause of death in the world. Choice of antibiotics are usually empirical…

Renal Cell Carcinoma
Overview Renal cell carcinomas (originate within the renal cortex) are responsible for 85% of all primary renal neoplasms. Transitional cell carcinomas of the renal pelvis are the next most common (~8%). Renal medullary carcinoma is a rare form of RCC seen in sickle cell disease. The most common pathological type of renal cell carcinoma is clear cell…

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…
