The treatment objective is to cure the disease and to prevent the evolution of the acute to the chronic form of the disease. All cases of suspected schistosomiasis should be treated regardless of presentation because the adult parasite can live in the host for years.Schistosomiasis is treatable by taking by mouth a single dose of the drug praziquantel annually.Praziquantel only eliminates the adult schistosomes, but it is not effective in killing the eggs and immature worms. Live eggs can be excreted by the infected individuals for weeks after treatment with Praziquantel. The immature worms can survive and grow up to be adult schistosomes after Praziquantel therapy. Thus, it is important to have repeated schistosomiasis testing of the stool and/or urine around 4–6 weeks after Praziquantel therapy. Treatment of Praziquantel may be repeated to ensure complete elimination of the parasite.The WHO has developed guidelines for community treatment based on the impact the disease has on children in villages in which it is common:
When a village reports more than 50 per cent of children have blood in their urine, everyone in the village receives treatment. When 20 to 50 percent of children have bloody urine, only school-age children are treated. When fewer than 20 percent of children have symptoms, mass treatment is not implemented.Other possible treatments include a combination of praziquantel with metrifonate, artesunate, or mefloquine. A Cochrane review found tentative evidence that when used alone, metrifonate was as effective as praziquantel.
An abscess of the thymus (also known as "Dubois abscesses") is a condition that is one of many possible causes of cysts in the mediastinum. It can present with chest pain behind the sternum.It can be associated with congenital syphilis.Although the thymus is usually classified with the immune system, thymic diseases are classified with endocrine disorders in ICD-9 and ICD-10.
