WHO IWGE classification?
WHO IWGE classification?
In 1995, the WHO-IWGE developed a standardised classification that could be applied in all settings to replace the plethora of previous classifications and allow a natural grouping of the cysts into three relevant groups: active (CE1 and 2), transitional (CE3) and inactive (CE4 and 5) (WHO and Echinococcosis, 2003).
What is human echinococcosis?
Human echinococcosis is a parasitic disease caused by tapeworms of the genus Echinococcus. The two most important forms in humans are cystic echinococcosis (hydatidosis) and alveolar echinococcosis.
What is Pericyst in Echinococcus cyst?
Pericyst, as the outermost layer of the hydatid cyst, is made by host cells encasing the hydatid cyst. An extremely close interaction exists between this host tissue and the parasite, and any degenerative changes of the pericyst would result in hydatid cyst degeneration or rupture.
What is Protoscolex?
noun. Medicine Zoology. A larval tapeworm contained in a brood capsule of an echinococcal cyst.
What are the symptoms of alveolar echinococcosis (AE)?
Pain or discomfort in the upper abdominal region, weakness, and weight loss may occur as a result of the growing cysts. Symptoms may mimic those of liver cancer and cirrhosis of the liver. What should I do if I think I have alveolar echinococcosis (AE)?
Can humans get alveolar echinococcosis from foxes?
Rare human cases have been reported in Alaska, the province of Manitoba, and Minnesota. Prevalence among wild foxes and coyotes can be high, and may reach over 50% in some areas; however, even in these areas, transmission to humans has been low. What are the symptoms of alveolar echinococcosis (AE)?
How many people are affected by Echinococcosis at one time?
More than 1 million people are affected with echinococcosis at any one time. Human echinococcosis is a zoonotic disease (a disease that is transmitted to humans from animals) that is caused by parasites, namely tapeworms of the genus Echinococcus. Echinococcosis occurs in 4 forms:
What are the symptoms of cystic echinococcosis / hydatid disease?
Cystic echinococcosis / hydatid disease. If the lung is affected, clinical signs include chronic cough, chest pain and shortness of breath. Other signs depend on the location of the hydatid cysts and the pressure exerted on the surrounding tissues. Non-specific signs include anorexia, weight loss and weakness.
