11/131. delusions of intestinal parasitosis.delusions of parasitosis, though uncommon, are an important cause of distress for affected patients and frequently of frustration for their physicians. They occur primarily in middle-aged or older women, who have the delusional belief that they are infested with parasites. Although the vast majority of cases involve dermatologic manifestations, some patients may have delusions of intestinal infection, as illustrated by this case.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
12/131. 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.- - - - - - - - - - ranking = 11keywords = infection (Clic here for more details about this article) |
13/131. Ultrasonographic features of pseudotumorous form of ascariasis.We report the ultrasonographic findings of a 60 year old woman with pseudotumorous form of ascariasis. Real-time ultrasonographic examination using a curved array transducer revealed grossly thickened small bowel loops, multiple small circular deposits throughout the peritoneal cavity, and a moderate amount of ascites. The English literature on the different forms of abdominal ascariasis is reviewed. Specific signs, which include the 'strip' sign, the 'four-lines', 'inner tube', or 'double tube' sign, the 'bull's eye' or 'target' sign, a 'worm mass' or 'spaghetti-like' appearance, and the 'zig-zag' sign can be present in any form of abdominal ascariasis, as they represent the image of the Ascaris worms visualized under ultrasonographic examination. However, the non-specific signs are not peculiar to A. lumbricoides infections, but are results of secondary changes due to A. lumbricoides infections in the corresponding organs.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
14/131. diphyllobothrium latum infection after eating domestic salmon flesh.diphyllobothrium latum infection in human is not common in korea and only thirty seven cases have been reported since 1921. We report two cases of fish tapeworm infection after ingestion of raw cherry salmon (oncorhynchus masou) caught in the domestic river. Among four family members who ate together raw salmon flesh six months ago, just two, mother and daughter, were infected. It is our expectation that the salmon associated tapeworm infections would be enlisted as one of the major parasitic problems with the growing consumption of salmon in korea.- - - - - - - - - - ranking = 7keywords = infection (Clic here for more details about this article) |
15/131. Uvitex 2B stain for the diagnosis of isospora belli infections in patients with the acquired immunodeficiency syndrome.OBJECTIVE: Fluorescent stains with Uvitex 2B or other fluorochromes are widely used today, especially for the diagnosis of microsporidian infections in human immunodeficiency virus (hiv)-infected patients. Our objective was to ascertain whether the fluorescent stain with Uvitex 2B is also able to detect isospora belli in stool samples and duodenal/bile juice of hiv-infected patients. DESIGN: Case study. SETTING: University hospital of the University of Cologne, germany. patients: Two hiv-infected patients with chronic diarrhea who had intestinal infections with I. belli. methods: Stool was concentrated by a modified water-ether sedimentation method, and duodenal/bile juice was concentrated by centrifugation. Wet-mount preparations were examined by phase-contrast and bright-field microscopy, and smears were stained with a modified acid-fast stain and a fluorescent stain with Uvitex 2B. RESULTS: Using the fluorescent stain with Uvitex 2B, the oocysts of I. belli stained bright white/blue fluorescent and showed a structure similar to that of the oocysts in acidfast stains. CONCLUSIONS: Staining with Uvitex 2B is a suitable method for the diagnosis of I. belli infections. This technique can be used for the diagnosis of three important gastrointestinal parasites (viz, microsporidia, cryptosporidia, and I. belli) responsible for diarrhea in hiv-infected patients.- - - - - - - - - - ranking = 7keywords = infection (Clic here for more details about this article) |
16/131. Pulmonary localization of enterocytozoon bieneusi in an AIDS patient: case report and review.enterocytozoon bieneusi is an agent of intestinal microsporidiosis leading to malabsorption syndrome and diarrhea in AIDS patients. Respiratory tract microsporidiosis due to encephalitozoon spp. has been reported. To date, however, only two cases of pulmonary involvement of E. bieneusi have been documented for patients with intestinal microsporidiosis. We report here another pulmonary localization of E. bieneusi in a human immunodeficiency virus-infected patient. Clinical features of these three cases are reviewed. E. bieneusi can colonize the respiratory tract but could be considered a simple carriage associated with an intestinal infection.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
17/131. Tropical malabsorption.Tropical malabsorption remains an important clinical problem for both the indigenous population of tropical countries and for short-term visitors and longer-term residents from the industrialized world. In young children, persistent diarrhea and malabsorption can result in severe retardation of growth and development. The most common cause is an intestinal infection notably the small intestinal protozoa including giardia intestinalis, cryptosporidium parvum, isospora belli, cyclospora cayetanensis, and the microsporidia. Tropical sprue still remains an important diagnostic option but is less common than it was 20 to 30 years ago. It is important to attempt to make a specific microbiological diagnosis as this will influence the choice of antibiotic. However, if laboratory facilities are not available, it is possible to offer empirical therapy although this may involve a trial of more than one antibiotic.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
18/131. Human intestinal anisakiosis due to consumption of raw salmon.Anisakiosis is a parasitic infection that follows consumption of raw or insufficiently pickled, salted, smoked, or cooked wild marine fish infected with anisakis sp. larvae. We report a case of intestinal anisakiosis in a 50-year-old man from quebec who presented with abdominal pain and peripheral eosinophilia after eating raw wild-caught salmon from the pacific ocean off canada. Abdominal CT scan showed bowel distension proximal to a segmental jejunal wall thickening, which was resected. The jejunum segment showed a localized area of serositis with mucosal edema and a submucosal abscess rich in eosinophils surrounding a parasite consistent with the third larval stage of anisakis sp. Diagnostic morphologic characteristics included an unpaired excretory gland (renette cell), Y-shaped lateral epidermal cords, no apparent reproductive system, and a ventriculus (glandular esophagus). These features and the absence of lateral alae excluded Ascaris sp. The absence of ventricular appendage and intestinal cecum excluded other anisakids of the genera Pseudoterranova and Contracaecum. As the popularity of eating raw fish is growing in north america, anisakiosis may be diagnosed more frequently in surgical specimens. This parasitic infection should be considered in the differential diagnosis of acute abdominal syndromes and eosinophilic infiltrates of the stomach, small intestine, colon, omentum, and mesentery, especially with a history of raw marine fish consumption.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
19/131. ascaris lumbricoides: an unusual cause of shunt infection.Two cases of delayed shunt infection attributable to the abdominal complications of ascaris lumbricoides infestation are reported. The first child presented with a peritoneal shunt catheter protruding through the anus and the second patient was found to have two live worms around the cephalic shunt tubing. Both had enteric shunt infections which responded well to therapy. The epidemiology and treatment of ascariasis are briefly discussed.- - - - - - - - - - ranking = 6keywords = infection (Clic here for more details about this article) |
20/131. Dipylidium caninum in an infant.The tapeworm, Dipylidium caninum, occurs worldwide in dogs and cats. It may occur rarely in children, when the infection may be unrecognised or misdiagnosed.
