Intestinal parasites cause significant morbidity and mortality. Diseases caused by Enterobius vermicularis, Giardia lamblia, Ar^cylostoma duodenale, Necator americanus, and
Entamoeba histolytica occur in the United States. E. vermicularis, or pinworm, causes irritation and sleep disturbances. Diagnosis can be made using the "cellophane tape test."
Treatment includes mebendazole and household sanitation. Giardia causes nausea, vomiting, malabsorption, diarrhea, and weight loss. Stool ova and parasite studies are diagnostic. Treatment includes metronidazole. Sewage treatment, proper handwashing, and
consumption of bottled water can be preventive. A. duodenale and N. americanus are
hookworms that cause blood loss, anemia, pica, and wasting. Finding eggs in the feces is
diagnostic. Treatments include albendazole, mebendazole, pyrante! pamoate, iron supplementation, and blood transfusion. Preventive measures include wearing shoes and
treating sewage. E. histolytica can cause intestinal ulcerations, bloody diarrhea, weight
loss, fever, gastrointestinal obstruction, and peritonitis. Amebas can cause abscesses in
the liver that may rupture into the pleural space, peritoneum, or pericardium. Stool and
serologic assays, biopsy, barium studies, and liver imaging have diagnostic merit. Therapy
includes luminal and tissue amebicides to attack both life-cycle stages. Metronidazole,
chloroquine, and aspiration are treatments for liver abscess. Careful sanitation and use of
peeled foods and bottled water are preventive. (Am Fam Physician 2004:69:1161-8. Copyright© 2004 American Academy of Family Physicians).
