It's important to avoid drinking alcohol during treatment. Even if you have to treat yourself, it's important to see a doctor to ensure that the treatment has been truly effective. [netdoctor.co.uk]
Prognosis
[…] may be involved, but typically the cecum and rectum are more severely affected a coexisting liver abscess may be seen the ileum is spared; helps to differentiate it from Crohn or tuberculosis, which typically involve the terminal ileum Treatment and prognosis [radiopaedia.org]
Outlook (Prognosis) Outcome is usually good with treatment. Usually, the illness lasts about 2 weeks, but it can come back if you do not get treated. [ufhealth.org]
It is very intractable, and when it is once thoroughly established, and the patient highly enervated, the prognosis is doubtful. [chestofbooks.com]
Etiology
Etiology Colitis, acute or chronic, caused by amebic dysentery, is not very frequently met with, yet often enough to be noticed in this place. It is said that in these cases there is a strong tendency for abscesses to form in the liver. [chestofbooks.com]
Etiologic Agent: Enatamoeba Histolytica Prevalent in unsanitary areas Common in warm climate Acquired by swallowing Cysts survives a few days outside of the body Cyst passes to the large intestine and hatch into trophozoites. [nursingcrib.com]
Needle aspiration is reserved for the following: Lesions of uncertain etiology Those in which rupture seems imminent Those that respond poorly to drug therapy Abscesses contain thick, semifluid material ranging from yellow to chocolate-brown. [merckmanuals.com]
Both of these infections, however, were greatly overshadowed by acute diarrhea of unrecognized etiology, which reached a peak incidence of 215 per annum per 1,000 strength in July 1944. [history.amedd.army.mil]
