1/4. Pyogenic abscesses and parasitic diseases.parasitic diseases which during their course in the host switch the immune system from a T helper 1 to a T helper 2 response may be detrimental to the host, contributing to granuloma formation, eosinophilia, hyper-IgE, and increased susceptibility to bacterial and fungal infections. patients and animals with acute schistosomiasis and hyper-IgE in their serum develop pyogenic liver abscess in the presence of bacteremia caused by staphylococcus aureus. The salmonella-S. mansoni association has also been well documented. The association of tropical pyomyositis (pyogenic muscle abscess) and pyogenic liver abscess with toxocara infection has recently been described in the same context. In tropical countries that may be an interesting explanation for the great morbidity of bacterial diseases. If the association of parasitic infections and pyogenic abscesses and/or fungal diseases are confirmed, there will be a strong case in favor of universal treatment for parasitic diseases to prevent or decrease the morbidity of superinfection with bacteria and fungi.- - - - - - - - - - ranking = 1keywords = parasitic infection (Clic here for more details about this article) |
2/4. Opportunistic parasitic infections in immunocompromised hosts.Parasitological and serological examination was done for 111 cases with various types of malignancies under immunosuppressive therapy and another 20 apparently healthy individuals as a control group to determine the prevalence of opportunistic parasitic infections among immunocompromised patients. Single examination showed that 74 (66.7%) harboured infection with different parasites: strongyloides stercoralis infection was found in 4 (3.64%) cases; 3 cases (2.7%) had pneumocystis carinii infection. No cryptosporidium oocysts were detected; IFAT for toxoplasmosis was positive in 40 cases (36%) with titres ranging from 1/16 - 1/256 but IFAT-IgM was negative. The control group did not show any parasitic infection except that IFAT was positive in 4 out of 20 (20%) with titres ranging from 1/16 to 1/128 but IFAT-IgM was also negative. Although toxoplasma infection was higher among patients the difference was insignificant. Generally the percentages recorded for the different parasites were found to be within the expected prevalence. One case report of concomitant opportunistic Pneumonocytis and toxoplasma infection is reviewed.- - - - - - - - - - ranking = 6keywords = parasitic infection (Clic here for more details about this article) |
3/4. AIDS and parasitic infections, including pneumocystis carinii and cryptosporidiosis.AIDS is a disorder that the pediatrician must consider when evaluating children with a variety of clinical conditions, including overwhelming infection with a number of parasites. This article discusses these opportunistic parasitic infections, focusing on their link with AIDS.- - - - - - - - - - ranking = 5keywords = parasitic infection (Clic here for more details about this article) |
4/4. Imported parasitic infections in tasmania.A number of protozoan, trematode, and nematode infections have been imported into tasmania over an 18-month period. Some of the cases are briefly discussed as they provide features of clinical interest. The increasing problem of imported infections in australia is emphasized.- - - - - - - - - - ranking = 4keywords = parasitic infection (Clic here for more details about this article) |
