Endometrial Cancer
Overview Endometrial carcinoma is an epithelial malignancy of the uterine corpus mucosa, usually an adenocarcinoma. Endometrial carcinoma is the most common female genital tract malignancy. Postmenopausal bleeding always needs to be investigated because it can indicate malignant disorders and premalignant conditions, such as endometrial hyperplasia. The most common etiology of postmenopausal bleeding is atrophic endometritis or vaginitis. Menopause:…

Primary Hyperaldosteronsim (Conn Syndrome)
Overview Primary hyperaldosteronism (also known as Conn syndrome when caused by a solitary aldosterone-producing adenoma) is an endocrine disorder characterized by the autonomous, unregulated overproduction of aldosterone from the zona glomerulosa of the adrenal cortex. Under physiological conditions, aldosterone secretion is regulated by the renin-angiotensin-aldosterone system (RAAS) and serum potassium levels. In primary hyperaldosteronism, aldosterone…

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…

Bipolar Disorder
Overview Bipolar disorder, previously termed manic depression, is a psychiatric diagnosis characterised by abnormally elevated or irritable mood episode(s) accompanied by disruptive symptoms of distractibility, indiscretions, grandiosity, flight of ideas, hyperactivity, decreased need for sleep, and talkativeness. It is well known that bipolar disorder carries with it high mortality and morbidity rates. The lifetime risk…

Pseudogout: Calcium Pyrophosphate Deposition Disease
Overview Pseudogout, more accurately known as calcium pyrophosphate deposition disease (CPPD), is a crystal arthropathy characterized by the deposition of calcium pyrophosphate dihydrate crystals in articular cartilage and soft tissues, leading to joint inflammation. It most commonly affects elderly individuals, especially over the age of 60, with a slight female predominance. Clinically, it often mimics…

RA Related Pleural Effusion
Overview Rheumatoid pleural effusion (RPE) is an uncommon extra‑articular manifestation of rheumatoid arthritis (RA), occurring in ~2–5% of patients, more often in middle‑aged men with high rheumatoid factor (RF) titres, despite RA being more common in women. It typically presents during active disease or in patients with rheumatoid nodules, but can occasionally precede joint symptoms.…

Pin Worms – Enterobius Vermicularis
Learn about Enterobius vermicularis, the pinworm responsible for one of the most common parasitic infections, especially in children. This video explains its life cycle, mode of transmission, symptoms, and diagnostic and treatment strategies.
Understanding Frozen Shoulder (Adhesive capsulitis)
Frozen shoulder, medically known as adhesive capsulitis, is a condition characterised by stiffness, pain, and limited range of motion in the shoulder joint. It typically develops gradually and can significantly impact daily activities. The condition is often linked to inflammation and tightening of the shoulder capsule. Common in people aged 40 to 60, especially those…
Pharmacology – HIV antiretroviral drugs (classes, mechanism of action and side effects)
Explore the major classes of HIV antiretroviral drugs, including their mechanisms of action in targeting different stages of the viral life cycle. This video also highlights common side effects, clinical uses, and the role of combination therapy in effective HIV management.
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…
