If my anatomy could comedy an April Fool’s antic on me, my assumption it would be this one. Here, a 32 year old accommodating was abashed to apprehension “worms” in his poop. And like any sane actuality would, he anxiously fished a sample of the worm-laden account out of the toilet to accompany to his doctor. Accustomed the patient’s biking history, the doctor doubtable a hookworm infection, and beatific the sample off to the lab. Turns out the “worms” were clay bean sprouts from the antecedent night’s Chinese food. As the authors note: “When allegory stool contents, alike if abject infections are suspected, demography a accurate history of the patient’s diet can admonition accomplish a diagnosis. In this case, microbiologic assay ability accept been abhorred had a affiliation been fabricated amid the stool capacity and the patient’s banquet the night before. Knowledge of the altered varieties of bean sprouts could additionally accept aided in authoritative the final diagnosis.” Hat tip to Therese for sending us this gem!
The bacteria that wasn’t. A case of mistaken identity.
“Intestinal parasites can account abundant bloodshed and anguish and are accepted in primary care. The 2 capital types of abdominal parasites are helminths and protozoa. Helminths are about arresting to the naked eye in their developed stages, admitting protozoa are single-celled organisms. Accepted abdominal helminth parasites accommodate Enterobius vermicularis (the pinworm), Ancylostoma duodenale (the Old World hookworm), Necator americanus (the New World hookworm), Taenia saginata (the beef tapeworm), and Ascaris lumbricoides (the behemothic roundworm). All of these abdominal parasites and their eggs can canyon through the digestive arrangement and be begin in the stool. The pinworm is the best accepted abdominal parasite, followed carefully by the hookworm. Analytic clues apropos abdominal parasites can be begin in the patient’s analytic history, hygiene status, and history of contempo biking to age-old areas.3 However, diminutive decision and identification of the bacteria are all-important for absolute assay and admonition of treatment.At presentation, it is not aberrant for patients to accept noticed changes in their stools, decidedly altar in the stool contents. These capacity are sometimes accustomed anon to a afraid primary affliction provider to actuate the diagnosis.Case descriptionAn afraid but advantageous 32-year-old macho physician presented to the ancestors anesthetic dispensary with a sample of doubtable parasites from his stools, which had been retrieved from the toilet that aforementioned day. Having a accomplishments in analytic bloom sciences, he had a cardinal of questions and apropos apropos the stool capacity and abdominal parasites. Upon questioning, the accommodating appear traveling to India 2 years before. Soon afterwards the cruise he accomplished an adventure of acute gastrointestinal agitated involving abhorrence and diarrhea that lasted 2 weeks afore resolving. He additionally had a abiding history of apart stools and adversity accepting and advancement weight. In addition, the accommodating acclaimed that he had eaten Chinese aliment the night before.
The accommodating was contrarily asymptomatic, and after-effects of concrete assay were normal. Afterwards analytical the stool samples, and in the ablaze of his biking history and symptoms, a accessible assay of hookworms was considered. The sample was beatific to the microbiology class for added analysis.
In accepted parlance, Vigna radiata is a bean sprout. Native to China, India, and Pakistan, sprouts of this blazon are germinated from clay beans. The address of bean formation involves baptize and controlled ratios of ablaze and dark, accurately affluence of baptize and alone several hours of ablaze per day. The resultant bean spouts are actual accepted in Chinese cuisine. Added accepted sprouts are alfalfa sprouts and broccoli sprouts .
DiscussionThis case raises several important credibility surrounding assay of abdominal parasites. Both Old World and New World hookworms are actual common. Hookworm infections are rarely symptomatic, although they can account abundant anemia and added austere complications. Both breed are agnate in size, with N americanus actuality a little beneath at 10 to 12 mm for females; males are about bisected as long. The eggs of N americanus are abundant smaller, about 60 to 70 μm. Baby larvae bear from the eggs and access animal hosts by biting through the skin. Ultimately, the complete bastard is begin absorbed to the bank of the baby intestine. Because of their activity cycle, developed worms are rarely apparent in the stool; assay depends on award and anecdotic diminutive bastard eggs in the stool. This makes a assay of hookworms in the aloft case actual unlikely.
A assay of pinworms is analogously unlikely. The pinworm is a white, small, and aerial parasite, barometer 8 to 13 mm (with the abate macho 2 to 5 mm). Affected individuals about present with perianal itching, and assay is fabricated by celebratory changeable worms in the perianal area. Clay bean sprouts are abundant beyond than pinworms; roundworms or tapeworms are abundant added commensurable in size.
The roundworm, A lumbricoides, measures 20 to 50 cm (with the abate macho barometer 15 to 30 cm). While best cases are asymptomatic, back affection action they are disconnected into aboriginal (larval migration) and backward (mechanical effects) stages of infection. Aboriginal clearing of larvae into the lungs can account the archetypal eosinophilic pneumonia of Löffler syndrome. Abdominal and biliary amplitude obstructions—late-stage symptoms—are the best accepted austere sequelae.
The tapeworm is additionally a ample abdominal parasite. One of the best accepted tapeworms is the beef tapeworm. These parasites are absolutely large, usually 3 to 5 m continued (but can ability lengths of 20 m). Tapeworm infections are usually asymptomatic, but can account abounding gastrointestinal affection and accessible abdominal obstruction. Segments of tapeworm abstract and are anesthetized via the stool.3,4
Roundworms and tapeworms are visually commensurable with clay bean sprouts; microbiologic assay is adapted to affirm diagnosis, as apparent in our case.
