Myotonic Dystrophy
Overview Autosomal dominant disease characterised by trinucleotide repeat of CTG. Also known as Dystrophica Myotoncia the disease is causes an increase in muscle tone (Myotonia) with associated degeneration and shrinkage of muscle fibres (Dystrophy). Myotonia: Delayed relaxation of skeletal muscle following voluntary contraction or mechanical stimulation (e.g., persistent grip after a handshake or a persistent…

Chronic Exertional Compartment Syndrome (Exercise-induced Compartment Syndrome)
Overview Chronic compartment syndrome (also known as chronic exertional compartment syndrome or exercise induced compartment syndrome) is an exertional condition in which repetitive activity causes transiently elevated pressure within a closed myofascial compartment, leading to ischemic pain, tightness, and sometimes neurologic symptoms that predictably begin with exercise and abate with rest. It most often affects…

Undifferentiated Connective Tissue Disease (UCTD)
Overview UCTD is a systemic autoimmune disease with features of connective tissue disease (CTD), but does not fulfill classification criteria for any specific CTD such as SLE, Sjögren’s syndrome, systemic sclerosis, or polymyositis. It is a diagnosis of exclusion used for patients with persistent autoimmune features who do not evolve into a defined CTD. Commonly…

Buerger’s Disease
Overview Buerger’s disease, also called thromboangiitis obliterans , is a non-atherosclerotic inflammatory and thrombotic disorder affecting small- and medium-sized arteries and veins, predominantly in the distal limbs. It is strongly associated with tobacco exposure and causes progressive digital ischaemia, superficial thrombophlebitis, painful ulcers and gangrene. 1–3 The disease classically affects younger people who smoke and…

Pre-operative Care
Overview Definition Perioperative Management refers to the period of time extending from the day prior to surgical intervention to several days after said intervention. It consists of the preoperative, intraoperative and postoperative period. Patient education Investigation used at surgery Coagulation status (ie. INR <2) Imaging scans for day of surgery Pre-operative care Aims: to provide…

Cervical Whiplash or Facet Joint Dysfunction
Overview Whiplash is an acceleration–deceleration mechanism that transfers energy to the neck, most commonly during a motor vehicle collision. The resulting bony or soft-tissue injury may produce a range of clinical manifestations collectively termed whiplash-associated disorders (WAD) . WAD commonly presents with neck pain, stiffness, restricted movement and headache. Some patients also experience shoulder or…

Anaphylaxis
Overview Anaphylaxis is a severe, systemic hypersensitivity reaction that is rapid in onset and potentially fatal, most often triggered by foods, medications, or venom; global incidence is ~50–112 per 100,000 person-years with rising emergency presentations in many regions, including Australia. Mortality is low but non-trivial and is driven by airway obstruction, severe bronchospasm, or distributive…

Pulmonary Embolism PART II
Explore the diagnosis and management of Pulmonary Embolism in this continuation video. Learn about clinical scoring systems, imaging techniques, and treatment options including anticoagulation and thrombolysis.
Tumour Lysis Syndrome (Tumor Lysis Syndrome) – pathophysiology, diagnosis and treatment
Tumour Lysis Syndrome is caused when tumour cells release their intracellular content into the bloodstream, either spontaneously or as a result of treatment leading to increased DNA – purine and pyrimidine, hyperkalemia, hyperphosphatemia leading to hypocalceamia and lactic acidosis.
Understanding Ear Pain – Otalgia (Innervation of ear, mechanism of ear pain and causes)
Understand the causes of ear pain (otalgia) through an overview of ear anatomy, innervation, and referred pain mechanisms. This video explains how different structures contribute to otalgia and reviews both primary and secondary causes.
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.
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…
