Liver Cysts
Authors Dr. Armando Faigl Areej zeeshan Ahmed Overview Liver cysts are fluid filled cavities in the liver that are asymptomatic and usually found incidentally on abdominal imaging. Larger cysts are more commonly associated with symptoms and complications. Clinical Manifestations Differential diagnosis for all liver cysts Liver abscess Benign tumors Malignant tumors Regenerative nodules Cholelithiasis GERD…

Biceps Tendon Rupture
Overview A biceps tendon rupture is a partial or complete tear of the tendon attaching the biceps muscle to the shoulder or elbow. Proximal ruptures, usually involving the long head of the biceps at the shoulder, are more common and often result from age-related degeneration or associated rotator-cuff disease. They typically cause upper-arm pain, bruising…

Ankle Sprain (Lateral Ligament Injury)
Overview A lateral ankle sprain is an injury to one or more ligaments on the lateral side of the ankle, usually caused by excessive inversion with the foot plantarflexed. The anterior talofibular ligament is injured most commonly, followed by the calcaneofibular ligament and, in severe injuries, the posterior talofibular ligament. 1 Most lateral ankle sprains…

Croup
Overview Croup, also known as largnotracheobronchitis, is a usually self limiting upper airway viral infection causing upper airway obstruction. Croup is more common in boys than in girls, usually occurs between six and 36 months of age, and peaks during the second year of life. Croup is usually caused by viruses, which are detected in up to…

Diabetes Mellitus type I
Overview Type 1 Diabetes Mellitus (T1DM) is a chronic, autoimmune metabolic disorder characterized by the progressive, T-cell-mediated destruction of insulin-producing pancreatic beta-cells within the Islets of Langerhans. This severe loss of functional beta-cell mass results in absolute insulin deficiency, leaving affected individuals entirely dependent on exogenous insulin for survival. Without sufficient insulin, tissues cannot take…

Antiphospholipid Syndrome (APS)
Overview Antiphospholipid Syndrome (APS) is an acquired autoimmune thrombophilia characterized by recurrent venous or arterial thromboses and/or pregnancy morbidity in the presence of persistent antiphospholipid antibodies (aPL). APS may occur as a primary condition or secondary to systemic lupus erythematosus (SLE). Prevalence of aPL in the general population is ~2%, but true APS is rare…

Acute Heart Failure
Overview Acute Heart Failure (AHF) is a life-threatening medical emergency defined as the rapid onset or sudden worsening of symptoms and signs of heart failure. It results from severe cardiac dysfunction leading to inadequate systemic cardiac output, elevated intracardiac pressures, or both. AHF can present either as de novo heart failure in a patient without…

Foot Drop – common peroneal nerve dysfunction
Understand foot drop, a condition often caused by common peroneal nerve dysfunction, leading to difficulty lifting the front part of the foot. This video explains the underlying anatomy, common causes, clinical signs, and approaches to diagnosis and treatment.
Immunology – Interleukin 6 (IL6) physiology and IL6 antagonist pharmacology Tocilizumab
Learn about Interleukin-6 (IL-6), a key cytokine involved in inflammation, immune regulation, and acute phase responses. This video also explains the pharmacology of IL-6 antagonists like tocilizumab, including their mechanism of action and clinical use in conditions such as rheumatoid arthritis and cytokine release syndrome.
Heart failure with reduced vs preserved ejection fraction – Pathophysiology and treatment
Heart failure explained: learn the causes, symptoms, tests, and treatments for heart failure with reduced and preserved ejection fraction. This video breaks down cardiac output, preload, afterload, contractility, and heart rate—the four determinants of heart performance—and shows how low cardiac output triggers compensatory mechanisms (Frank–Starling, sympathetic activation, RAAS) that can worsen ventricular remodeling. Viewers will…
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.

Student, Neelain University
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…
