Neural Tube Defect
Overview Neural tube defects (NTDs) are a group of major congenital anomalies comprising anencephaly, spina bifida and encephalocele that result from very early disruption in the development of the brain and spinal cord. These conditions are often incompatible with life. Survivors frequently require intensive, costly, lifelong health and social care. Neural tube defect (NTD): Severe…

Acute cholangitis
Overview Cholangitis means inflammation of the bile ducts. In clinical practice, the term commonly refers to acute cholangitis —an acute bacterial infection of the biliary system that usually develops when bile duct obstruction permits bacterial proliferation and impairs biliary drainage. It is a potentially life-threatening emergency because infection can rapidly progress to bacteraemia, sepsis and…

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…

Catastrophic Antiphospholipid Syndrome (CAPS)
Overview Catastrophic antiphospholipid syndrome (CAPS) is a rare, life-threatening form of antiphospholipid syndrome (APS) characterised by rapidly developing thrombosis affecting multiple organs, typically over days. Small-vessel thrombosis and thrombotic microangiopathy are prominent, although large-vessel arterial or venous thromboses may occur simultaneously. 1 CAPS is a medical emergency . The combination of widespread thrombosis, systemic inflammation…

Candida Infections
Overview Candida species are yeasts that normally colonise human skin and the gastrointestinal and genitourinary tracts. Disease occurs when local microbial balance or epithelial defences are disrupted, or when organisms enter normally sterile tissues. Candida infections range from oropharyngeal, oesophageal, vulvovaginal and cutaneous candidiasis to invasive disease such as Candidaemia, intra-abdominal candidiasis, endocarditis, endophthalmitis, osteoarticular…

Diabetes Mellitus Type II
Overview Diabetes Mellitus type II is a progressive disorder defined by deficits in insulin secretion and action (insulin resistance). 1 in 12 people have diabetes (50% do not know they have it). Diabetes type II accounts for over 90% of all diabetes cases. The remaining 10% include type I diabetes. People with type II diabetes…

Resuscitation of Newborn
Overview The successful transition from intrauterine to extrauterine life is dependent upon significant physiologic changes that occur at birth. Successful transition – 90% Need some intervention – 10% Require extensive resuscitative measures - 1% High-risk Delivery Infants who are more likely to require resuscitation can be identified by the presence of one or more of…

Pharmacokinetics Overview | ADME, Bioavailability, Half-Life & Clearance
Master pharmacokinetics quickly: ADME (absorption, distribution, metabolism, excretion) explained with real-world examples and clinical relevance. In this concise video you’ll learn how drugs enter the body, reach tissues, are chemically transformed, and are removed—key concepts like bioavailability, first-pass metabolism, volume of distribution, protein binding, clearance, and half-life are clearly defined and applied. Watch to understand…
Neuromuscular Junction
Explore the step-by-step process of neuromuscular transmission, from acetylcholine release to muscle fiber contraction. This high-yield video is perfect for mastering the neuromuscular junction for exams like the USMLE, NCLEX, or PLAB.
Kidney stones – pathophysiology and management
Kidney stones explained: causes, symptoms, diagnosis, and practical treatments to relieve pain and prevent recurrence. This video covers kidney stones (nephrolithiasis/urolythiasis), why they form, who’s at risk, and the most effective clinical approaches. You’ll learn clear anatomy of the urinary tract, how nephron function and urine supersaturation lead to crystal and stone formation, and 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.
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…
