Of the many parasitic infestations involving worms, pinworms are the most prevalent form of worm infestation. They affect approximately 200 million people all over the world, one-third of which can be found in the United States. Genus Enterobius or pinworm, is a parasitic roundworm belonging to the phylum Nematoda.
The liver and spleen share common blood circulation pathways. Due to the circulatory link between the liver and spleen, many disease processes affect both organs. Infections, blood cell diseases, liver diseases, cancer and inherited disorders can adversely affect the liver and spleen, causing enlargement of both organs. Any disease process that causes ongoing liver inflammation -- or chronic hepatitis -- and subsequent liver scarring can lead to cirrhosis.
Like any other organ in the body, spleen is also susceptible to various diseases and infections. These conditions can cause enlargement of this organ, which is referred as splenomegaly. This disorder can seriously impede the myriad functions of spleen in the body.
