Pericarditis
Overview Pericarditis is the most common form of pericardial disease and a relatively common cause of chest pain. The etiology of pericarditis may be infectious (eg, viral and bacterial) or noninfectious (eg, systemic inflammatory diseases, cancer, and post-cardiac injury syndromes). Tuberculosis is a major cause of pericarditis in developing countries but accounts for less than 5%…

Atypical Pneumonia
Overview Atypical pneumonia is a clinical term traditionally used for pneumonia caused by organisms that do not have a cell wall, live intracellularly, or are not detected on routine bacterial culture. Important causes include Mycoplasma pneumoniae , Chlamydia pneumoniae , Legionella species, Chlamydia psittaci and Coxiella burnetii . Respiratory viruses can produce a similar syndrome.…

Liver Cirrhosis Complications
Portal Hypertension Overview Normal portal vein pressure is 5–10mmHg. Portal hypertension develops when the portal pressure is greater than 12mmHg. Mechanism of disease Increased Intrahepatic resistance of blood flow through the liver due to cirrhosis Increased splanchnic blood flow secondary to vasodilation leading to increased portal flow through liver Cirrhosis is the most common…

Nephritic Syndrome
Overview Nephritic syndrome is one of two clinical patterns seen in glomerular disease. Nephritic Syndrome is characterised by haematuria, proteinuria, hypertension and oligouria. Nephritic syndrome can be further classified based on light microscopic features: Focal Diffuse Glomerular Disease: Disease effecting the glomerulus. Glomerular disease reduces the ability of the kidneys to maintain a balance of certain substances in…

Acute Respiratory Failure
Overview Acute Respiratory Failure (ARF) is a life-threatening impairment of the respiratory system's ability to maintain adequate gas exchange. It occurs when the lungs fail to adequately oxygenate systemic arterial blood, fail to eliminate carbon dioxide produced by tissue metabolism, or both. ARF is not a disease entity in itself, but rather a sudden, critical…

Hodgkins Lymphoma
Overview Hodgkin lymphoma (HL) arises from germinal center or post-germinal center B cells. HL has a unique cellular composition, containing a minority of neoplastic cells ( Reed-Sternberg cells and their variants) in an inflammatory background. Reed-Sternberg cell is a characteristic feature of HL. Epidemiology Lymphoma is divided into Hodgkins and Non-Hodgkins Hodgkins lymphoma accounts for…

Chronic Intestinal Ischaemia
Overview Chronic intestinal ischaemia, more commonly called chronic mesenteric ischaemia , results from an inadequate increase in intestinal blood flow after eating. It is usually caused by atherosclerotic narrowing of one or more mesenteric arteries. Patients classically develop recurrent postprandial abdominal pain, leading to reduced food intake, fear of eating and progressive weight loss. Diagnosis…

Understanding Carpal Tunnel Syndrome and Carpal Tunnel Anatomy
Carpal tunnel syndrome (CTS) is a common condition caused by compression of the median nerve as it passes through the wrist’s carpal tunnel. It often results in symptoms like numbness, tingling, pain, and weakness in the hand and fingers, especially the thumb, index, and middle fingers. CTS is frequently associated with repetitive hand movements, prolonged…
Pancreas Clinical Anatomy and Physiology
Learn the essential clinical anatomy and physiology of the pancreas, including its endocrine and exocrine functions. This video highlights its role in digestion, glucose regulation, and relevance to conditions like diabetes and pancreatitis.
Endocrinology – Glucagon
Learn the key functions of glucagon in glucose metabolism, including its role in glycogenolysis, gluconeogenesis, and ketogenesis. This educational video highlights how glucagon maintains blood sugar during fasting, with clinical insights relevant to diabetes and endocrine physiology.
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.
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…
