1/10. A human case of Stellantchasmus falcatus infection in Korea.In an attempt to find the worm producing unidentified egg, one minute fluke was collect from a Korean patient after praziquantel administration. The fluke was identified to be Stellantchasmus falcatus by the expulsor. Brackish water fish was suggested to be a probable source of the infection.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
2/10. Clinostomum trematode from human eye.The first human case of Clinostomum lacramalitis in thailand is reported. A 38-year-old man visited an ophthalmology clinic after having itchy pain in the right eye for two days. Ophthalmological examination revealed a living worm adhered to the lacramal opening and after removal, it was identified as Clinostomum sp. The patient admitted that he used to eat raw freshwater fish, he caught in Prachin Buri Province where he lives.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
3/10. An outbreak of trematode-induced granulomas of the conjunctiva.PURPOSE: To describe the epidemiologic, clinical, and histopathologic features of trematode granulomas of the conjunctiva, eyelid, and anterior chamber in pediatric patients. DESIGN: Prospective noncomparative case series. PARTICIPANTS: Forty-one children from a southern Indian village with conjunctival granulomas. methods: The village of Sellananthal was selected for a field visit after analysis of earlier hospital-based allergic conjunctival granuloma cases. Children with ocular diseases were examined, and histories of exposure to assumed risk factors and clinical findings were evaluated. Selected patients were brought to the base hospital for excisional biopsy. Serial sections obtained from the excised nodules were examined for the presence of a parasite. MAIN OUTCOME MEASURES: Histopathologic examination of excised conjunctival lesions or response of lesions to local medical therapy. RESULTS: In this year-long prospective study, 41 children (16 years or younger; 38 boys and 3 girls) with clinical features of allergic conjunctival granulomas were examined. Thirty-four patients were from a single village located in the southern Indian state of Tamil Nadu; the remaining 7 were from various parts of the same state. All children swam in their village's freshwater pond. Twenty patients with nodules less than 5 mm in diameter received medical treatment; 13 with larger nodules underwent surgical excision of the lesions. Nine of these 13 cases revealed a zonal granulomatous inflammation admixed with eosinophilic leukocytes; 4 of these 9 displayed fragments of the tegument and internal structures of a trematode and Splendore-Hoeppli phenomenon. The remaining 4 of the 13 cases revealed nongranulomatous inflammation made up of lymphocytes, histiocytes, and eosinophils. Eight patients refused surgical treatment. CONCLUSIONS: In southern india, one cause of allergic conjunctival granulomas in children seems to be trematode infection. The clustering of cases in a single village and exposure to a village freshwater pond indicate the need for an epidemiologic investigation and study of the parasite's life cycle. Sporadic cases from other parts of the state with similar histories of exposure to their local pond or river water suggest a widespread distribution of the etiologic agent.- - - - - - - - - - ranking = 3keywords = water (Clic here for more details about this article) |
4/10. Fasciolopslasis--a re-emerging infection in Azamgarh (Uttar Pradesh).Fasciolopsiasis is endemic in the far east. In india, there have been a few reports of the infection, prior to the 1990's. We report two cases from Azamgarh district of Uttar Pradesh. Both the cases were from nearby villages where water chestnuts are cultivated. These may be a source of infection. Pigs are commonly observed in these areas and and may be the source of ova. The only missing link is the finding of infected snails. Presence of at least three cases (one reported earlier) in the area indicates the potential for the infection to re-emerge. Further epidemiological studies are needed to analyse the various ecological factors of transmission. Fasciolopsiasis is endemic in china, taiwan, vietnam and thailand. In india, (Fascilopsis buski) infections in man have been reported earlier from Assam, Maharashtra, Tamil Nadu and parts of Uttar Pradesh. However, to the best of our knowledge, no such reports have been made since 1990's. We herewith report two recent cases from district Azamgarh, Uttar Pradesh (U.P.), india. Factors, such as cultivation of water chestnuts, presence of snails as intermediate hosts and pigs as definitive host in this geographical area seem to be suggestive of an endemic focus and thus needs further epidemiological survey for preventive and control measures, at the earliest.- - - - - - - - - - ranking = 2keywords = water (Clic here for more details about this article) |
5/10. Fasciolopsiasis: a first case report from malaysia.Fasciolopsiasis is a disease caused by the largest intestinal fluke, Fasciolopsis buski. The disease is endemic in the far east and Southeast asia. Human acquires the infection after eating raw freshwater plants contaminated with the infective metacercariae. There has been no report of fasciolopsiasis either in man or in animal in malaysia. We are reporting the first case of fasciolopsiasis in malaysia in a 39-year-old female farmer, a native of Sabah (East malaysia). This patient complained of cough and fever for a duration of two weeks, associated with loss of appetite and loss of weight. She had no history of traveling overseas. physical examination showed pallor, multiple cervical and inguinal lymph nodes and hepatosplenomegaly. Laboratory investigations showed that she had iron deficiency anemia. There was leukocytosis and a raised ESR. Lymph node biopsy revealed a caseating granuloma. Stool examination was positive for the eggs of Fasciolopsis buski. The eggs measure 140 x 72.5 microm and are operculated. In this case, the patient did not present with symptoms suggestive of any intestinal parasitic infections. Detection of Fasciolopsis buski eggs in the stool was an incidental finding. She was diagnosed as a case of disseminated tuberculosis with fasciolopsiasis and was treated with antituberculosis drugs and praziquantel, respectively.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
6/10. A human case of Stellantchasmus falcatus infection.A human case infected with Stellantchasmus falcatus(heterophyidae) is reported based on the adult worms collected after praziquantel treatment. The patient is a 33-year old male residing in Seoul. For several months he experienced vague abdominal discomfort and hunger pain. praziquantel at a single dose of 600 mg was given followed by purgation with magnesium salt, and 17 adult S. falcatus specimens were collected from the diarrheal stools. He recalled he had eaten raw flesh of several kinds of brackish water fishes. This is the 4th human case of S. falcatus infection in Korea.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
7/10. Intestinal fluke infection as a result of eating sushi.Severe diarrhea in a female outpatient was caused by an intestinal fluke, identified as Heterophyes heterophyes, a natural parasite of humans and domesticated and wild fish-eating mammals. This parasite is endemic in the Orient and the middle east. A detailed case history revealed that the woman had never traveled outside the continental united states but became infected while eating raw fresh-water fish (sushi) that had been served at a local Japanese restaurant. The restaurant specialized in serving a great variety of fresh-water and salt-water fish that were flown in from the Orient and other parts of the world. The authors' findings indicate that a person does not have to travel to an endemic area to become infected with this organism.- - - - - - - - - - ranking = 3keywords = water (Clic here for more details about this article) |
8/10. The first human case of Clinostomum complanatum (trematoda: Clinostomidae) infection in Korea.The authors present the first human case of Clinostomum pharyngitis in Taegu, Korea. The patient was a 56-year old male who visited an otolaryngology clinic due to foreign body sensation and pain of the pharyngeal region for 3-4 days. He used to eat raw fresh-water fish. Otolaryngological examinations revealed a living worm adhered to the right posterior pharyngeal wall. The worm removed was identified as C. complanatum after morphological observations. It is likely that more attention should be paid to eating raw fresh-water fish in Korea with regards to Clinostomum pharyngitis.- - - - - - - - - - ranking = 2keywords = water (Clic here for more details about this article) |
9/10. A human case of Plagiorchis muris (Tanabe, 1922: Digenea) infection in the republic of korea: freshwater fish as a possible source of infection.A Korean man was found infected with Plagiorchis muris and 2 other intestinal trematodes, echinostoma hortense and Metagonimus takahashii. No complaint of gastrointestinal discomfort due to these fluke infections was noted. The patient had a history of eating various kinds of freshwater fish caught from a small stream near his village. Freshwater fish collected from the stream were examined for trematode metacercariae by an artificial digestion technique. Unidentified metacercariae collected were administered to a Sprague-Dawley rat. One P. muris adult was recovered from the small intestine of the rat on day 8 postinfection. Thus, freshwater fish of the genera Liobagrus, Puntungia, and Odontobutis are a probable source of infection for this patient.- - - - - - - - - - ranking = 7keywords = water (Clic here for more details about this article) |
10/10. One human case of natural infection by Heterophyopsis continua and three other species of intestinal trematodes.The third human case of natural infection by Heterophyopsis continua in Korea was found in Chinju, Kyongsangnam-do. The case was a 53-year-old man. He used to eat raw brackish and fresh water fish. After praziquantel treatment and purgation, H. continua were collected from the diarrheal stool together with Metagonimus yokogawai, Heterophyes nocens and echinostoma hortense. His clinical complaints were indigestion, epigastric discomfort, poor appetite and fatigue. The complaints were considered rather due to heavy M. yokogawai infection.- - - - - - - - - - ranking = 1keywords = water (Clic here for more details about this article) |
