Tuberculosis
Overview Tuberculosis (TB) is a chronic, communicable infectious disease caused by the acid-fast bacillus Mycobacterium tuberculosis . It primarily affects the pulmonary parenchyma but possesses the capacity to disseminate to virtually any organ system via hematogenous and lymphatic spread. TB remains one of the leading infectious causes of mortality worldwide, representing a major global public…

Liver Mass I Tumour
Author Armando Faigl MBBS Areej zeeshan Overview Liver tumors are divided into Benign and Malignant. Most liver tumors are benign, asymptomatic and found incidentally on unrelated imaging. Malignant liver tumours are associated with risk factors (Hep C, Cirrhosis) and present with a spectrum of clinical signs and symptoms such as right upper quadrant pain and…

Juvenile Idiopathic Arthritis (JIA)
Overview Juvenile Idiopathic Arthritis (JIA) is an umbrella term encompassing a heterogeneous group of chronic inflammatory arthritides of unknown etiology presenting in children under 16 years of age. It represents the most common chronic pediatric rheumatic disease, with an estimated prevalence of 1 in 1,000 children. To meet the diagnostic criteria, arthritis must persist for…

Post‑splenectomy Immunodeficiency
Overview Post‑splenectomy immunodeficiency refers to the increased susceptibility to infection following removal (or functional loss) of the spleen. The spleen plays a critical role in filtering bloodborne pathogens, especially encapsulated bacteria, and in mounting both innate and adaptive immune responses. Loss of splenic function leads to impaired opsonisation, reduced IgM production, and defective clearance of…

Schizophrenia
Overview Schizophrenia is a complex syndrome often presenting in late teens/early 20s with positive, negative and cognitive symptoms. Positive symptoms include behaviours and thoughts that are not normally present (psychosis). Negative symptoms include social withdrawal and affective flattening. Finally, cognitive symptoms are expressed as a broad set of cognitive dysfunction. The average lifetime prevalence of…

Temporal Arteritis (Giant Cell Arteritis)
Overview Giant cell arteritis (GCA), also known as temporal arteritis or cranial arteritis, is the most common systemic vasculitis in adults. It is a granulomatous panarteritis that selectively targets medium and large-sized arteries, displaying a strong tropism for the branches of the external carotid artery (particularly the superficial temporal artery) and the aorta. The disease…

Sexual Transmitted Infection
Overview Sexually transmitted infections (STI) are a significant public health worldwide. STI can result in chronic disease, pregnancy complications, infertility, and even death. Globally, congenital syphilis is still a leading cause of stillbirth and neonatal death. Antibiotic-resistant Neisseria gonorrhoeae continues to be a significant public health concern. Chlamydia trachomatis infection is the most frequently reported…

Explanations learners return to.

Fat (lipid) digestion and absorption physiology
Explore the physiology of fat digestion and absorption, from emulsification by bile salts to breakdown by pancreatic enzymes. This video explains how lipids are processed, absorbed in the small intestine, and transported via chylomicrons into the lymphatic system.

Molecular effects of Butyrate
Discover the molecular effects of butyrate, a short-chain fatty acid, on gut health, inflammation, and gene expression. This video explains how butyrate influences epigenetic regulation, immune modulation, and intestinal barrier integrity. Video was part of 2014 Summer Scholarship Project with CSIRO called "The Hungry Microbiome" For more visit: http://www.csiro.au/hungrymicrobiome/

Relapsing Polychondritis
Learn about Relapsing Polychondritis, a rare autoimmune disorder affecting cartilage in areas like the ears, nose, and respiratory tract. This video covers clinical features, pathophysiology, and current treatment approaches for effective diagnosis and 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.
“The notes I make during his videos help me retain everything better.
“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…
