Osteonecrosis of the Hip
Overview Osteonecrosis of the hip, usually referring to osteonecrosis of the femoral head (ONFH), is a progressive disorder caused by compromised subchondral blood supply leading to death of osteocytes and marrow elements, failed structural repair, subchondral fracture, femoral head collapse, and eventually secondary hip osteoarthritis. [1-4] It most often affects younger to middle-aged adults, commonly…

Acute Coronary Syndrome: Myocardial infarction (STEMI, NSTEMI)
Overview Acute coronary syndrome (ACS) describes acute myocardial ischaemia caused by an abrupt reduction in coronary blood flow. It includes myocardial infarction (MI) and unstable angina and is a time-critical medical emergency. This article focuses on ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). 1 Myocardial infarction is diagnosed when there is…

Acute Compartment Syndrome
Overview The muscle groups of the human limbs are divided into section or compartments. Acute compartment syndrome (ACS) occurs when increased pressure within a compartment compromises circulation and function of tissues within that area. common sites of ACS is the leg and forearm. Acute compartment syndrome: A critical pressure increase within a confined compartmental space causing…

Rhinosinusitis
Overview Rhinosinusitis is an inflammatory condition affecting the mucous membranes of both the nasal cavity and the paranasal sinuses (maxillary, ethmoid, frontal, and sphenoid). The clinical term "rhinosinusitis" is preferred over "sinusitis" because inflammation of the paranasal sinuses almost never occurs without concurrent inflammation of the contiguous nasal mucosa. It is one of the most…

Hyperthyroidism (Thyrotoxicosis)
Overview The most common cause of hyperthyroidism are Graves disease, multinodular goitre, an autonomously functioning thyroid nodule (adenoma) and subacute thyroiditis. Graves Disease is more common in women. Multinodular goitre is more common in the elderly. Graves disease typically manifests in middle aged women. Thyroid diseases are more common in women. Hyperthyroidism: denote conditions in which…

Parkinson Plus Syndrome
Overview Parkinson-Plus syndromes (also known as atypical parkinsonism ) are a heterogeneous group of neurodegenerative diseases characterized by parkinsonian features—bradykinesia, rigidity, tremor, and gait impairment—occurring alongside additional ("plus") prominent neurological signs. These extra features typically include early postural instability with falls, vertical supranuclear gaze palsy, severe autonomic failure, cerebellar ataxia, early cognitive decline, or cortical…

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

Cervical Radiculopathy
Overview Cervical radiculopathy is dysfunction of a cervical nerve root caused by irritation or compression as it leaves the spine. It commonly produces pain radiating from the neck into one arm, sometimes with paraesthesia, numbness, weakness or altered reflexes. A disc herniation or degenerative narrowing of the neural foramen is a common cause. Diagnosis is…
