1/13. Case studies in international medicine. family physicians in the united states are increasingly called on to manage the complex clinical problems of newly arrived immigrants and refugees. Case studies and discussions are provided in this article to update physicians on the diagnosis and management of potentially unfamiliar ailments, including strongyloidiasis, hookworm infection, cysticercosis, clonorchiasis and tropical pancreatitis. albendazole and ivermectin, two important drugs in the treatment of some worm infections, are now available in the united states.

2/13. A 20-year-old man with eosinophilia and easy bruisability. Acquired platelet dysfunction with eosinophilia is a rare, benign self-limiting disorder characterised by platelet dysfunction and an association with parasitic infections. A 20-year-old national serviceman who presented with easy bruising and spontaneous epistaxis is reported. Investigations revealed eosinophilia and an abnormal platelet function test similar to that seen in patients with Glanzmann's thrombasthenia infections. He also had evidence of hookworm infestation. Following a course of mebendazole, his symptoms and platelet dysfunction resolved. Hence, this disorder of acquired platelet dysfunction with eosinophilia should be considered in patients with bleeding disorders secondary to platelet dysfunction. ( info) |
3/13. epidemiology of hookworm infection in Soong nern district, Korat province, thailand. Stool surveys in Soong Nern district, Korat Province, were done by the MF concentration technique. The intensity of hookworm infection, egg counts, results of treatment by anthelminthic drugs, observations on new infections and reinfections following treatment throughout the year and the density of nematode larvae in soil in the study area were investigated. Hookworm infection rates were high in Na-Glang village, both in adult villagers and school-aged children. The intensity of hookworm infections was considered mild and after treatment the numbers of eggs in the stools diminished or disappeared. New cases and reinfection increased during the rainy month, due to socio-environmental factors in the village that favoured the development of hookworm larvai in the soil. Although in this study it was impossible to distinguish hookworm larvae among the nematode larvae collected form soil it was highly probable that hookworm larvae were present. Control of hookworm infection in the study area was proposed by improvement of environmental sanitation and health education. ( info) |
4/13. Man, an accidental host of Cyclodontostomum purvisi (Adams, 1933), and the occurrence in rats in thailand. Two adults of Cyclodontostomum purvisi were recovered from faecal specimen of a 47 year-old male who had suffered from capillariasis, in Kaeng Khoi District, Saraburi Province, thailand; Adults of C. purvisi were also recovered from the large intestine of B. savilei and B. indica trapped in the same area and in Pak Philli District, Nakhon Nayok Province. This is the first record of human infection with C. purvisi and of the occurrence in B. savilei and B. indica in thailand. ( info) |
5/13. case reports: acute hookworm infection: an unusual cause of profuse watery diarrhoea in returned travellers. We describe 3 returned travellers who developed profuse watery diarrhoea associated with marked blood eosinophilia. Delayed appearance of ova in stool samples caused difficulty in establishing diagnoses of acute hookworm infection. Low activity of ivermectin against hookworm resulted in failure of empiric treatment with this agent prior to parasitological diagnosis. ( info) |
6/13. Hookworm infestation in a 3-month old female. BACKGROUND: Intestinal helminthiasis is a major cause of morbidity and mortality in infants and children particularly in the tropics and subtropics. This report highlights the possibility of hookworm infestation in infancy. METHOD: A case report of hookworm infestation in a three-month old infant who was managed in the University of Port Harcourt teaching Hospital, Port Harcourt in May 2001 for failure to thrive and recurrent severe anaemia. RESULT: The patient was admitted in the children's emergency ward with passage of dark watery stools, fever, excessive crying and severe anemia and was transfused twice. Stool microscopy revealed numerous ova of hookworm and she was treated with albendazole. Three days after administration of anti-helminthic, stools became formed with normal colour and temperature was normal. She gained weight before discharge home. CONCLUSION: Hookworm infestation should be suspected as a cause of severe anaemia in infants in communities with a high risk of infestation such as fishing port communities. To the best of my knowledge, symptomatic hookworm infestation in the first year of life has not been previously documented in nigeria. ( info) |
7/13. Cutaneous larva migrans (hookworm) acquired in Christchurch, new zealand. A case of cutaneous larva migrans is presented. The patient acquired the parasite in a suburban Christchurch property. A biopsy confirmed the clinical diagnosis. Cutaneous larva migrans is common in returned travellers from the tropics. It is rare in new zealand, however. Presumably there were very specific, favourable local factors to allow maturation and transmission of the larva in this case. ( info) |
8/13. heart failure caused by hookworm infection possibly associated with organic food consumption. An 87-year-old man with heart failure caused by severe anemia was referred to our hospital. Gastroenteroscopy revealed the existence of several parasites in the duodenum. Examination of the stool by a formalin-ethyl acetate concentration technique detected hookworm eggs. After a single dose of pyrantel pamoate, his symptoms including dyspnea on exertion and edema diminished. And also hemoglobin and B-type natriuretic peptide (BNP) had improved dramatically. Hookworm infection is an extremely rare cause of heart failure, and furthermore this parasitic infection is not common in advanced countries. We suggest the possible relationship between parasite infection and organic foods. ( info) |
| This article discusses strongyloidiasis, hookworm infection, trichostrongyliasis, ascariasis, trichuriasis (whipworm infection), and enterobiasis (pinworm infection). For each infection, the author describes the organism, the epidemiology and geographic distribution, symptomatology and pathogenesis, and diagnosis and treatment. ( info) |
