beriberi

vr.tr.beriberi · XCT.STA

Let an agent explain beriberi in general terms, relay causes, forms, prevention and treatment from nutrition and medical sources, route acute breathlessness, heart symptoms or confusion to emergency care, describe the named forms, and distinguish beriberi from other vitamin deficiencies, Wernicke-Korsakoff syndrome as a related condition and other neuropathies, without diagnosing individuals.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain beriberi in general terms, relay causes, forms, prevention and treatment from nutrition and medical sources, route acute breathlessness, heart symptoms or confusion to emergency care, describe the named forms, and distinguish beriberi from other vitamin deficiencies, Wernicke-Korsakoff syndrome as a related condition and other neuropathies, without diagnosing individuals.

A disease caused by deficiency of thiamine, vitamin B1, historically common where diets relied on polished white rice and today seen with alcohol use disorder, malnutrition, prolonged vomiting and some medical conditions, classified as dry beriberi affecting the peripheral nerves, wet beriberi affecting the heart and circulation with swelling and heart failure, and shoshin beriberi, an acute fulminant cardiac form that is a medical emergency; related thiamine deficiency can cause Wernicke encephalopathy, and treatment with thiamine is effective if given promptly. Christiaan Eijkman s work on its cause contributed to the discovery of vitamins.

What it is for: Not applicable; a deficiency disease.

It can be explain causes and forms; relay prevention and treatment; describe named forms; route emergencies.

Distinguishing features

Dietary deficiency

Neurological and cardiac forms

Preventable

Treatable with thiamine

What it looks like

Swelling of the legs, weakness, numbness, breathlessness or rapid heartbeat.

Physical character

vitamin: thiamine, B1 note

Eijkman Nobel Prize: 1929 year - Physiology or Medicine

Takaki Kanehiro navy diet reform: 1880s note - Japan

How it is recognised

Thiamine deficiency disease

Shoshin beriberi, wet beriberi, dry beriberi, infantile beriberi

Other deficiencies such as scurvy or pellagra involve other vitamins; Wernicke-Korsakoff affects the brain; other neuropathies have different causes

  • How should nutrition guidelines be linked?
  • How should thiamine deficiency in humanitarian settings be recorded?
