Lateral and Medial Elbow Tendinopathy (Epicondylitis)
Overview Medial and lateral elbow tendinopathies are common overuse injuries affecting the common flexor and extensor tendon origins at the elbow, respectively. Commonly known as Golfer's Elbow (medial) and Tennis Elbow (lateral), these conditions are primarily degenerative (tendinosis) rather than inflammatory (tendinitis), resulting from repetitive microtrauma and failed healing responses. Lateral Elbow Tendinopathy (Tennis Elbow…

Otitis Externa
Overview Otitis externa is an acute or chronic inflammation of the external auditory canal, which extends from the tympanic membrane to the pinna. It is predominantly a localized bacterial infection caused by a breakdown in the natural protective barriers of the ear canal—namely cerumen, an acidic pH, and an intact epithelial lining. Frequently referred to…

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…

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…

Brain Abscess
Overview A brain abscess is a focal, encapsulated suppurative infection originating within the brain parenchyma. It begins as a localized area of unencapsulated parenchymal inflammation (cerebritis) that evolves over days to weeks into a pus-filled core surrounded by a vascularized collagen capsule. Despite significant advances in neuroimaging, stereotactic neurosurgery, and broad-spectrum antimicrobial therapy, a brain…

Post Traumatic Stress Disorder
Traumatic and Stress Related Disorders Post traumatic stress disorder Acute stress Disrorder Adjustment Disorder This will mainly focus on PTSD Overview The identification of Post traumatic stress disorder (PTSD) in a patient involves understanding the traumatic event and the patient characteristics. PTSD may develop following exposure to 1 or more traumatic events such as deliberate acts of interpersonal…

Umbilical and Epigastric Hernia
Overview Umbilical and Epigastric hernias are types of Primary Ventral abdominal wall hernias. Epigastric hernias are two to three times more common in men. Umbilical hernias are three times more likely in females. Most epigastric hernias contain preperitoneal fat, while most umbilical hernias contain omentum or bowel. These hernias are usually asymptomatic unless incarcerated, obstructed…

Achalasia (esophageal) – signs and symptoms, pathophysiology, investigations and treatment
Achalasia is a rare disorder that results from progressive destruction of ganglion cells in the myenteric plexus of the oesophageal wall. The destruction of these cells leads to the inability of the lower oesophageal sphincter to relax, and leads to the loss of peristalsis of the distal oesophagus. As a result there is dilatation of…
Nervous System – Resting Membrane Potential
Understand the resting membrane potential and how ion gradients and membrane permeability maintain electrical balance in neurons. This high-yield video is essential for grasping nerve physiology in exams like the USMLE, NCLEX, or NEET.
Ano In Fistula
Discover the causes, symptoms, and treatment options for anal fistulas, a painful condition often resulting from infection or abscess near the anus. This video provides a clear overview of the pathophysiology, diagnosis, and surgical management of ano-in fistula.
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.

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.

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.
Aspiration Pneumonia
Overview Aspiration pneumonia is an acute pulmonary infection caused by inhalation of bacteria-rich oropharyngeal or upper gastrointestinal material into the lower respiratory tract. It occurs when aspiration is combined with impaired airway protection, ineffective clearance and sufficient pathogenic bacterial burden. It is particularly important in older adults, people with neurological disease, frailty, dysphagia or reduced…
