Non-Hodgkins Lymphoma
Non-Hodgkin lymphoma (NHL) consists of a diverse group of malignant neoplasms variously derived from B cell progenitors, T cell progenitors, mature B cells, mature T cells, or (rarely) natural killer cells.
View topic ↗Paediatric Respiratory Distress Syndrome
Overview Respiratory distress syndrome (RDS) also known as hyaline membrane disease is a pulmonary disease resulting from immature lung development and surfactant deficiency. Most frequently seen in preterm infants, the clinical presentation is characterized by signs of respiratory distress including nasal flaring, tachypnea, and grunting (an expiratory sound that is heard as the infant exhales…
View topic ↗Anal Fissure
Overview Anal fissure is a split in the skin of the distal anal canal. It presents with severe pain on defecation, like passing “glass shards”, and rectal bleeding. It is more frequently diagnosed in younger and middle-aged individuals. Anal fissures are mostly caused by passage of hard stool but can also be a result of…

Types of Lymphoma Lymphoma is malignancy originating in the lymph nodes. There are two types: Hodgkins lymphoma Non-hodgkins lymphoma Classic Clinical Presentation Lymphadenopathy Constitutional symptoms Fever Night sweats Weight loss Differential Diagnosis of Lymphadenopathy Lymphoma Leukaemia Metastasis Infection Connective tissue disease – rheumatoid arthritis, SLE Infiltration – sarcoidosis Drugs – phenytoin Hodgkin's lymphoma Non-Hodgkin's lymphoma…
View topic ↗Thyroiditis
Overview Thyroiditis: Varied group of disorder all characterized by some form of thyroid inflammation Hyperthyroidism: denote conditions in which hyperfunction of the thyroid leads to thyrotoxicosis. Hypothyroidism: Variety of abnormalities that cause insufficient secretion of thyroid hormones. The most common cause is autoimmune thyroid disease Thyrotoxicosis: denotes the clinical, physiological, and biochemical findings that result…
View topic ↗Birth Defects
Overview Birth defects are the leading cause of perinatal and post- neonatal deaths, and result in substantial morbidity and disability in developed countries. There is a wide variety of mechanisms including genetic, environmental and multifactorial. Major birth defects affect 2–3% of live-borns, and minor birth defects affect 15%. Preventative strategies remain limited, but include maternal folic acid supplementation,…
View topic ↗Chronic Exertional Compartment Syndrome (Exercise-induced Compartment Syndrome)
Overview Chronic compartment syndrome (also known as chronic exertional compartment syndrome or exercise induced compartment syndrome) is an exertional condition in which repetitive activity causes transiently elevated pressure within a closed myofascial compartment, leading to ischemic pain, tightness, and sometimes neurologic symptoms that predictably begin with exercise and abate with rest. It most often affects…

Giardiasis overview
Giardiasis causes watery, greasy diarrhea, bloating, and weight loss—learn how Giardia lamblia is transmitted, diagnosed, treated, and prevented to protect yourself and vulnerable populations. In this concise video you'll discover the Giardia life cycle (cysts and trophozoites), common transmission routes (fecal-oral, contaminated water and food), and why half of infections can be asymptomatic. Watch to…

The Brainstem Clinical Anatomy – Rule of 4's, midbrain, medulla, pons
Learn the clinical anatomy of the brainstem using the Rule of 4’s to simplify the organization of key cranial nerve nuclei and tracts. This video breaks down the structures and functions of the midbrain, pons, and medulla, and explains how lesions at each level present clinically.

Endoplasmic Reticulum
Explore the structure and functions of the endoplasmic reticulum, including the roles of the rough and smooth ER in protein synthesis, lipid metabolism, and detoxification. This video explains how the ER integrates into the cellular system and supports essential biological processes.
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.
“The notes I make during his videos help me retain everything better.
“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.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
