Umbilical Hernia
Overview Umbilical hernias are one of the most common surgical conditions in infants and children. In infantile umbilical hernia there is a pathological failure of obliteration of umbilical defect. Umbilical hernia can also occur in adults and is usually acquired due to increased intrabdominal pressure due to obesity, pregnancy, ascites. Management is surgery. Hernia: A bulge or protrusion of…

Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…

Addison's Disease
Overview Addison's disease is a disease characterised by adrenal insufficiency. Adrenal insufficiency results in a decrease of the adrenal gland hormones: mineralocorticoids, glucocorticoids and to an extent androgens. There are many causes of addison's disease. The most common cause in the developed world is autoimmune (approximately 70% cases). Signs and symptoms of adrenal sufficiency don't…

Amyloidosis (AA type)
Overview Amyloid A (AA) amyloidosis is a systemic disorder caused by extracellular deposition of insoluble fibrils derived from persistently elevated serum amyloid A (SAA), an acute-phase protein produced mainly by the liver. It occurs as a complication of sustained inflammation from chronic inflammatory, autoinflammatory, infectious or, less commonly, neoplastic disease. 1 The kidneys are affected…

Tarsal Tunnel Syndrome
Overview Tarsal Tunnel Syndrome (TTS), also known as posterior tibial nerve neuralgia, is an entrapment neuropathy caused by compression of the tibial nerve or its terminal branches within the fibro-osseous tarsal tunnel beneath the flexor retinaculum on the medial side of the ankle. It represents the lower extremity analogue of Carpal Tunnel Syndrome. Because the…

Acute Kidney Injury (AKI)
Overview Acute Kidney Injury (AKI) and Acute Kidney Disease (AKD) describe a spectrum of sudden decline in renal function occurring over hours to days, characterized by a rapid drop in glomerular filtration rate (GFR), accumulation of nitrogenous waste products (azotemia), and deregulation of extracellular fluid volume and electrolytes. Under the KDIGO framework, AKI represents acute…

Asthma
Overview Asthma is a chronic airway inflammation disorder due to complex interactions between inflammatory cells, mediators and airway cells. In young children in whom lung function testing is not feasible, including most preschool children, asthma is defined by the presence of variable respiratory symptoms. Asthma is one of the most common causes of presentation to the Emergency…

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.

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…
