Acute Cholecystitis
Overview Acute cholecystitis is acute inflammation of the gallbladder, usually caused by a gallstone obstructing the cystic duct. Persistent obstruction causes gallbladder distension, inflammation and possible secondary bacterial infection. Most cases are calculous, while acalculous cholecystitis occurs mainly in critically ill or severely immunocompromised patients. Cholecystectomy: surgical removal of the gallbladder. Calculous cholecystitis: gallbladder inflammation…

Systemic Sclerosis-Associated Interstitial Lung Disease
Overview Systemic sclerosis–associated interstitial lung disease (SSc-ILD) is one of the most common and severe internal organ manifestations of systemic sclerosis (SSc), occurring in up to 50–60% of patients on HRCT, with clinically significant disease in ~25–30%. It is a major cause of SSc-related mortality. The most frequent histopathological pattern is nonspecific interstitial pneumonia (NSIP),…

Systemic Sclerosis (SSc)
Overview Systemic sclerosis (SSc), also known as scleroderma, is a rare chronic autoimmune connective tissue disease characterized by fibrosis, vasculopathy, and autoimmunity. It primarily affects the skin but can also involve the lungs, GI tract, kidneys, and heart. The estimated prevalence is 50–300 per million, with a female-to-male ratio of ~4:1, and peak onset between…

Endometriosis
A healthy 25-year-old woman presents with worsening dysmenorrhea, pain of recent onset in the left lower quadrant, and dyspareunia. She has regular menstrual cycles, and her last menstrual period was 3 weeks before presentation. She has been trying to fall pregnant over the past 10 months without success and she is becoming more concerned. Overview…

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…

Adrenal Crisis
Overview Adrenal crisis is an acute, life-threatening state of cortisol deficiency that causes haemodynamic instability and may rapidly progress to shock, hypoglycaemia, electrolyte disturbance, altered consciousness and death. It may be the first presentation of adrenal insufficiency or occur when glucocorticoid availability is inadequate during physiological stress. 1–3 Clinical suspicion is sufficient to begin treatment.…

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…

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.
Inflammatory vs non-inflammatory arthritis
Inflammatory arthritis refers to a group of conditions characterised by a high number of white cells in the joints, causing inflammation, pain, redness, and swelling. Non-inflammatory arthritis typically refers to wear-and-tear joint problems, such as osteoarthritis. In this video, we will compare osteoarthritis (a classically non-inflammatory arthritis) to rheumatoid arthritis (a common inflammatory arthritis).
Bilirubin Metabolism
Understand bilirubin metabolism, from the breakdown of hemoglobin to its processing in the liver and excretion in bile. This video explains the steps involved, including conjugation, transport, and the clinical relevance of elevated bilirubin levels.
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

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…
