Polycystic Kidney Disease
Overview The polycystic kidney diseases are among the most common life-threatening inherited diseases worldwide and frequently cause kidney failure. Autosomal dominant polycystic kidney disease (ADPKD) is seen predominantly in adults, whereas autosomal recessive polycystic kidney disease (ARPKD) is mainly a disease of childhood. For ADPKD, screening asymptomatic at-risk adults with a family history by ultrasound…

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…

Infective Endocarditis
Overview Infective endocarditis is a condition which occurs in the setting of bacteraemia whereby endothelial surfaces of the heart, such as valvular structures, become infected. It can present acutely or subacutely, and is often associated with fevers, new heart murmurs, constitutional symptoms and embolic phenomena. The classical organism associated is Staphylcoccus aureus, however there are…

Snapping Hip Syndrome (Coxa Saltans)
Overview Snapping Hip Syndrome (SHS) is characterized by an audible or palpable “snap” around the hip during motion; it may be painless or painful and can be unilateral or bilateral. Prevalence estimates suggest up to ~5–10% of the general population may experience snapping to some degree, with higher rates in dancers and athletes who work…

Microscopic Polyangiitis
Overview Microscopic polyangiitis (MPA) is a small-vessel necrotizing vasculitis, commonly associated with myeloperoxidase-ANCA (MPO-ANCA) positivity. It typically presents with glomerulonephritis and pulmonary capillaritis, but does not involve granulomatous inflammation, distinguishing it from GPA.Incidence: ~3–24 cases per million annually; more common in middle-aged adults and slightly more frequent in males. 1 MPO-ANCA (Myeloperoxidase-ANCA): An autoantibody typically…

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…

Transient Ischaemic Attack (TIA)
Overview Transient ischemic attack is defined as transient neurologic symptoms without evidence of acute infarction. It is a common and important risk factor for future stroke. TIAs are produced by temporary ischemia to a vascular territory, usually caused by thrombosis or embolism and less commonly by vasculitis, hematologic disorders such as sickle cell disease or…

Hiccups in Babies: Why do they do it so much?
Hiccups in infants are common and usually harmless, often caused by feeding, swallowing air, or a developing digestive system. Most infant hiccups resolve on their own and don’t require treatment, but burping and upright positioning can help reduce episodes.
Parasites Overview
Parasites are microorganisms that live on a living host and derive nutrition them without any benefit to the host. Parasites can also cause harm to the infected host. There are three classes of parasites that cause infections in humans: Protozoa, Helminths, Ectoparasites.
Croup (laryngotracheobronchitis) – pathophysiology and management
Learn how to recognize, treat, and manage croup — the common viral laryngotracheobronchitis that causes barking cough, inspiratory stridor, and breathing difficulty in young children. Croup (laryngotracheobronchitis) most often affects kids aged 6 months to 3 years and is usually viral — commonly parainfluenza or RSV — causing inflammation and subglottic swelling that produces the…
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.
Biliary Atresia
Overview Biliary atresia is a progressive fibro-inflammatory disorder of infancy in which the extrahepatic bile ducts—and variably the intrahepatic ducts—become obliterated. This prevents bile from draining from the liver, producing conjugated hyperbilirubinaemia, progressive hepatic fibrosis and, without treatment, cirrhosis and liver failure. Affected infants often appear well during the first weeks of life. Persistent jaundice…
