[Cystic echinococcosis in Turkey from 2001-2005]. / Türkiye'de 2001-2005 Yillari Arasinda Kistik Ekinokokkozis.

Cystic echinococcosis (CE) caused by the metacestode form of Echinococcus granulosus is a major public health problem especially in animal-raising regions of the world. In the present study, CE cases were determined during 2001-2005 by investigating different hospital and health directorship documents and Health Ministry documents, retrospectively. Our results show that there were 2534 (13.13%) cases in the Marmara region; 2114 (16.94%), in the Aegean region; 2578 (16.09%), Mediterranean region; 5404 (38.57%), in the Middle Anatolian region; 428 (5.70%), in the Black Sea region; 844 (6.80%), in the eastern Anatolian region; and 887 (2.75%), in the southeastern Anatolian region making a total of 14,789 CE cases. Finally, it has been determined that the patients were hospitalized for a total of 149,464 days.

Effects of Cd(+2), Cu(+2), Ba(+2) and Co(+2) ions on Entamoeba histolytica cysts.

AIM: The effects of cobalt, copper, cadmium and barium ions on the cysts of Entamoeba histolytica (E. histolytica), an amebic dysentery agent, cultured in Robinson medium were investigated. METHODS: E. histolytica cysts and trophozoites isolated from a patient with amebiasis were cultivated in the medium, incubated at 37 degrees for a period of 4 days and 40 x 10(4)/ml amebic cysts were then transferred to a fresh medium. At the second stage, 0.05, 0.1 and 0.2 mM of selected metal ions were added to the medium, and the effects of these ions on parasitic reproduction compared with the control group were observed. RESULTS: It was determined that the number of living parasites in all the groups containing metal ions decreased significantly starting from 30 minutes (P<0.01). CuCl2 showed the highest lethal effect on E. histolytica cysts, whereas the lowest lethal effect was observed with CoCl2. It was also seen that the number of living cells was decreased as the ion concentration and exposure time were increased, and that there were no living parasites in the medium at the end of 24 h (P<0.01). CONCLUSION: It may be stated that the effect of ever-increasing contamination of the environment with metal waste materials on parasites should be investigated further.

Incidence of toxoplasmosis in patients with cirrhosis.

AIM: It is known that toxoplasmosis rarely leads to various liver pathologies, most common of which is granulomatose hepatitis in patients having normal immune systems. Patients who have cirrhosis of the liver are subject to a variety of cellular as well as humoral immunity disorders. Therefore, it may be considered that toxoplasmosis can cause more frequent and more severe diseases in patients with cirrhosis and is capable of changing the course of the disease. The aim of this study was to investigate the frequency of toxoplasmosis in patients with cirrhosis. METHODS: Serum samples were taken from 108 patients with cirrhosis under observation in the Hepatology Polyclinic of the Gastroenterology Clinic, and a control group made up of 50 healthy blood donors. IFAT and ELISA methods were used to investigate the IgG and IgM antibodies, which had developed from these sera. RESULTS: Toxoplasma IgG and IgM antibody positivity was found in 74 (68.5%) of the 108 cirrhotic patients and 24 (48%) of the 50 people in the control group. The difference between them was significant (P<0.05). CONCLUSION: In conclusion, it was found that the toxoplasma sero-prevalence in the cirrhotic patients in this study was higher. Cirrhotic patients are likely to form a toxoplasma risk group. More detailed studies are needed on this subject.

Prevalence of amebiasis in inflammatory bowel disease in Turkey.

AIM: To explore the prevalence of amebiasis in inflammatory bowel disease (IBD) in Turkey. METHODS: In this study, amoeba prevalence in 160 cases of IBD, 130 of ulcerative colitis and 30 of Crohn's disease were investigated in fresh faeces by means of wet mount+Lugol's iodine staining, modified formol ethyl acetate and trichrome staining methods and to compare the diagnostic accuracy of wet mount+Lugol's iodine staining, modified formol ethyl acetate and trichrome staining methods in the diagnosis of Entamoeba histolytica (E. histolytica)/ Entamoeba dispar (E. dispar). RESULTS: E. histolytica/E. dispar cysts and trophozoites were found in 14 (8.75 %) of a total of 160 cases, 13 (10.0 %) of the 130 patients with ulcerative colitis and 1 (3.3 %) of the 30 patients with Crohn's disease. As for the 105 patients in the control group who had not any gastrointestinal complaints, 2 (1.90 %) patients were found to have E. histolytica /E. dispar cysts in their faeces. Parasite prevalence in the patient group was determined to be significantly higher than that in the control group (Fischer's Exact Test, P<0.05). When the three methods of determining parasites were compared with one another, the most effective one was found to be trichrome staining method (Kruskal-Wallis Test, P<0.01). CONCLUSION: Consequently, amoeba infections in IBD cases have a greater prevalence compared to the normal population. The trichrome staining method is more effective for the detection of E. histolytica /E. dispar than the wet mount+Lugol's iodine staining, modified formol ethyl acetate methods.
