Toxic Multinodular Goitre

Overview Toxic Multinodular Goitre (TMNG) is the second most common cause of hyperthyroidism caused by a long-standing goitre and/or iodine deficiency which results in an increased risk of mutation and consequent TSH-independent autonomic function of thyroid nodules to produce excess thyroid hormones. Common clinical manifestations include hyperthyroidism and a painless thyroid goitre with palpable nodules.…

Pyoderma Gangrenosum

Overview Pyoderma gangrenosum (PG) is a rare, severe, non-infectious inflammatory cutaneous disease belonging to the group of neutrophilic dermatoses . Despite its name, it is neither an infectious pyoderma nor a primary gangrenous necrosis; rather, it is driven by dysregulated innate immune activation leading to dermal neutrophilic infiltration and tissue destruction. Characterized by rapidly expanding,…

Tuberculosis

Overview Tuberculosis (TB) is a chronic, communicable infectious disease caused by the acid-fast bacillus Mycobacterium tuberculosis . It primarily affects the pulmonary parenchyma but possesses the capacity to disseminate to virtually any organ system via hematogenous and lymphatic spread.

Paediatric Orthopaedics Overview

Osteochondroses Osteochondroses is a condition that affects the epiphysis of bones. Pathology consists of localised area of ischaemic bone necrosis and oedema of adjacent soft tissue. Osteochondroses result in avascular necrosis of the epiphyseal bone, similar to Perthes disease, but less common. In general osteochondroses is more troublesome than serious. Age effects usually 10-15 +/-…

Bowel Obstruction

Overview Bowel obstruction is a blockage of intestinal contents, either mechanical (e.g., adhesions, hernias, malignancy) or functional (e.g., ileus), leading to impaired transit, proximal dilation, and downstream complications including ischaemia and perforation if untreated. Key features of bowel obstruction include colicky abdominal pain, distension, nausea with bilious or faeculent vomiting, obstipation, initially high-pitched then absent…

Hand-drawn explanations that build the big picture as the concept unfolds.

02 / READ

Notes

Clear written explanations for review, reference and filling in the details.

03 / SEE

Diagrams

Visual snapshots that help you easily review topics.

04 / CHECK

Questions

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.

01

See it clearly

Turn abstract processes and invisible relationships into something the learner can picture.

02

Connect the pieces

Build understanding around how concepts fit together—not a pile of isolated facts.

03

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.

Chronic inflammatory demyelinating polyneuropathy (CIDP)

Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
