In most cases, the symptoms of threadworm infestation include: Intense itching in the anal region at night when the worms lay eggs. Inflammation of the anus as a result of constant scratching. In some cases, mild abdominal pain. Sometimes, tiny, white threadworms can be seen wriggling in the faeces after a bowel movement. In rare cases, infestation causes appendicitis. What might be done? The diagnosis can be confirmed by identification of threadworm eggs in a swab taken from the anal region. Your doctor will probably prescribe an anthelmintic drug to kill the worms effectively and speed recovery. Usually, the entire household is treated.
Aetiology. Acute appendicitis is caused by infection of the appendix wall following obstruction of the lumen. The obstruction may be due to a faecolith (a hard lump of faeces that may form when transit time is prolonged), lymphadenitis, intestinal worms or a stricture from previous inflammation.
