What causes podoconiosis?
Podoconiosis is a chronic inflammatory, geochemical skin disease caused by prolonged exposure to irritant red clay soils derived from volcanic rocks [2] and causes bilateral asymmetrical swelling of the lower legs. Podoconiosis is a neglected disease, although currently it does not appear on the WHO list of NTDs.
What is the difference between elephantiasis and podoconiosis?
Podoconiosis is a type of lower limb tropical elephantiasis distinct from lymphatic filariasis. Lymphatic filariasis affects all population at risk, whereas podoconiosis predominantly affects barefoot subsistence farmers in areas with red volcanic soil.
What does podoconiosis mean?
Podoconiosis (endemic non-filarial elephantiasis) is a geochemical disease in individuals exposed to red-clay soil derived from alkalic volcanic rock.
Is podoconiosis an ntd?
In 2011 the World Health Organization (WHO) recognized podoconiosis as one of the neglected tropical diseases (NTDs) under the category of ‘other tropical conditions’.
What is Milroy’s disease?
Milroy disease is a condition that affects the normal function of the lymphatic system. The lymphatic system produces and transports fluids and immune cells throughout the body. Impaired transport with accumulation of lymph fluid can cause swelling (lymphedema ).
What causes mossy foot?
Unlike lymphatic elephantiasis, which is contracted when a parasitic worm is transmitted to humans by mosquitoes, podoconiosis – also known as “mossy foot” because it causes moss-like warts called hyperkeratotic papilloma – is contracted by walking barefoot on irritant volcanic soils.
What is elephantiasis Nostras Verrucosa?
Elephantiasis nostras verrucosa (ENV) is a rare and dramatic sequela of chronic nonfilarial lymphedema. The condition is characterized by papules, verrucous lesions, enlargement, and woody fibrosis of the affected area.
What is podoconiosis and what causes it?
According to the World Health Organization “Evidence suggests that podoconiosis is the result of a genetically determined abnormal inflammatory reaction to mineral particles in irritant red clay soils derived from volcanic deposits”.
What is podoconiosis ( elephantiasis)?
Podoconiosis, also known as nonfilarial elephantiasis, is a disease of the lymphatic vessels of the lower extremities that is caused by chronic exposure to irritant soils. It is the second most common cause of tropical lymphedema after lymphatic filariasis, and it is characterized by prominent swelling…
What kind of spider is black with white spots?
The most famous is the black widow spider that can cause a non-fatal nasty bite. However, poisonous spiders can also be brown, black with white spots, or black with a red body. It is important to identify the correct species of spider to tell harmless house spiders apart from ones that bite.
What is the difference between filariasis and podoconiosis?
The differential diagnosis for podoconiosis includes other causes of tropical lymphedema, such as filariasis or leprosy, and mycetoma pedis. While filariasis is generally unilateral, podoconiosis affects the legs bilaterally albeit asymmetrically and in an ascending manner.
