    Methods: A total of 88 patients' endoscopic and colonoscopic pre-washed materials, which consisted of 49 individuals who belong former group and 39 individuals to the next group, were, respectively, obtained, and the stool samples were also included to study from the same group. All the specimens were immediately transferred to the parasitology research laboratory within the same day and stored C until for the next step of ELISA applications.
    Results: All the samples were examined by direct microscopy and ELISA method. In the examinations performed using the ELISA method;
    Conclusion: In patients with gastrointestinal complaints and undergoing endoscopy and colonoscopy, investigation of the presence of parasites by stool examination with direct microscopy may be insufficient. In addition to the direct examination of the stool sample, it is thought that the investigation of parasite antigens in the wash/swab materials that can be easily taken during the endoscopy and colonoscopy procedure is necessary and critical in the diagnosis.

    Abstract Objective:In this study, it was aimed to investigate the presence of Entamoeba histolytica, Giardia intestinalis and Cryptosporidium spp. in the samples taken during the procedure from patients who underwent endoscopy and/or colonoscopy with different prediagnoses, and in the stools of the same patients, by ELISA and direct microscopy methods.Methods:A total of 88 patients’ endoscopic and colonoscopic pre-washed materials, which consisted of 49 individuals who belong former group and 39 individuals to the next group, were, respectively, obtained, and the stool samples were also included to study from the same group. All the specimens were immediately transferred to the parasitology research laboratory within the same day and stored C until for the next step of ELISA applications.Results:All the samples were examined by direct microscopy and ELISA method. In the examinations performed using the ELISA method; E. histolytica was detected in 2 (2.3%) stool samples, and G. intestinalis was found in 4 (4.5%) stool samples. In the colonoscopic wash/swab samples of the patients who underwent colonoscopy, 6 (6.8%) G. intestinalis, 1 (1.1%) Cryptosporidium spp. detected. No parasites were detected by ELISA in any of the stool samples or endoscopic washing/swab samples of the patients who underwent colonoscopy. No parasites were detected in stool and wash/swab samples by the direct examination method.When the incidence of G. intestinalis in washing/swab samples taken from patients who underwent endoscopy and colonoscopy was statistically compared, the difference was found to be significant (p<0.05). When the incidence of G. intestinalis in the stools of patients who underwent endoscopy was compared, the difference between genders was found to be significant (p<0.05).Conclusion:In patients with gastrointestinal complaints and undergoing endoscopy and colonoscopy, investigation of the presence of parasites by stool examination with direct microscopy may be insufficient. In addition to the direct examination of the ...

    Abstract Background: Relaxing the sphincter of Oddi (SO) is an important process during endoscopic retrograde cholangiopancreatography (ERCP) procedures. This issue suggests that the easier the sphincterotomy and cannulation, the more post-ERCP complications decrease.
    Aims: To compare the relaxant effects of ataciguat (a novel soluble guanylyl cyclase activator) and zaprinast (an inhibitor of phosphodiesterase 5) on sheep SO in vitro, thus testing whether they can be used during ERCP.
    Study design: Animal experimentation.
    Methods: Sheep SO rings were placed in tissue baths and their isometric tension to ataciguat and zaprinast were tested. We also tested their isometric tension against ataciguat in the presence of 1H-(1,2,4) oxadiazole (4,3-a) quinoxalin-1-one (ODQ) which is a soluble guanylyl cyclase inhibitor.
    Results: Ataciguat and zaprinast both triggered concentration addicted relaxation on sheep SO rings (p=0.0018, p=0.0025 respectively) but the relaxation of the ataciguat was significantly greater than that of zaprinast at all concentrations (p=0.0024). It was observed that decreased relaxation responses were initiated by ataciguat in the presence of ODQ (p=0.0012).
    Conclusion: Ataciguat and zaprinast both have relaxing effects on sphincter of Oddi, although that of zaprinast is lower. We believe that ataciguat and zaprinast can be used in ERCP procedures in order to relax the sphincter of Oddi and thus can be used locally in order to decrease complications.

    Abstract Although it is rare, drug-induced thrombocytopenia is important since it may cause fatal results like bleeding. Mostly spironolactone is used for ascites palliation in the cirrhotic patients. Thrombocytopenia has been reported with thiazide group of diuretics. But thrombocytopenia caused by spironolactone is rarely seen. We presented our patient with ascites diagnosed as liver cirrhosis that developed severe thrombocytopenia after receiving two weeks of spironolactone treatment.

    Abstract Introduction: Chronic hepatitis C (CHC) infection is a systemic disorder that can lead to liver inflammation, fibrosis, cirrhosis, and hepatocellular cancer. The mean platelet volume (MPV) is widely used as an inflammatory marker to evaluate the platelet function and the status of systemic inflammation.
    Aim: To determine the pre- and post-treatment MPV values in CHC patients who were administered a 48-week antiviral therapy based on systemic inflammation.
    Material and methods: We enrolled 28 patients, diagnosed with CHC genotype 1b, who received a 48-week antiviral therapy and attended regular follow-up, and 28 healthy individuals. In diagnosing CHC, a positive anti-HCV for a minimum duration of 6 months and a positive serum HCV RNA were accepted as the criteria. The patients were assigned to one of two groups based on their group 1 (pre-treatment values) and group 2 (post-treatment values) after 3 months therapy. We analysed and compared the blood samples of all of the groups.
    Results: The MPV value was 8.89 ±1.20 in group 1 and 8.00 ±1.07 in group 2, and 8.21 ±1.18 in the control group. The value in group 1 was detected to be statistically significantly different from that in group 2 and the control group (
    Conclusions: The results of this study suggest that MPV could represent an inexpensive marker for use in assessing low-grade inflammation in patients with CHC.

    Abstract Familial Mediterranean fever (FMF) is an ethnically restricted disease with an autosomal recessive inheritance characterized by recurrent attacks of fever, painful manifestations in the abdomen, chest and joints. The disease affects mainly non-Ashkenazi Jews, Armenians, Turks Arabs and other people of Mediterranean origin. The disease may present at any age, more than 80% of patients being symptomatic by the age of 20. Although the inflammatory attacks that characterize the disease may sometimes be debilitating, secondary (AA) amyloidosis remains the most serious manifestation of FMF causing considerable morbidity due mostly to nephropathic amyloidosis. The largest series of secondary amyloidosis in FMF have been reported from Turkey. The pathophysiological steps in progressing a patient from FMF to amyloidosis are not definitely known. Daily treatment with colchicine can prevent both the attacks and amyloid deposition but no effective alternative treatment exists for colchicine resistant cases. Meanwhile more population based epidemiological and genetic data should be gathered by worldwide collaborative studies to elucidate the link between FMF and amyloidosis and to develop alternative therapies.

    Abstract Caroli's disease is a rare congenital condition chara-cterized by non-obstructive saccular or fusiform dilatation of larger intrahepatic bile ducts. Cholangitis, liver cirrhosis, and cholangiocarcinoma are its potential complications. The diagnosis of Caroli's disease depends on demonstrating that the cystic lesions are in continuity with the biliary tree which can be showed by ultrasonography, computerized tomography, endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography or magnetic resonance cholangiopancreatography. Treatment of Caroli's disease relies on the location of the biliary abnormalities. While localized forms confined to one lobe can be treated with surgery, liver transplantation is the only effective modality for diffuse forms. Although a rare disorder; Caroli's disease should always be considered in the differential diagnosis of chronic cholestasis of unknown cause.

    Abstract Caroli's syndrome is characterized by multiple segmental cystic or saccular dilatations of intrahepatic bile ducts associated with congenital hepatic fibrosis. The clinical features of this syndrome reflect both the characteristics of congenital hepatic fibrosis such as portal hypertension and that of Caroli's disease named as recurrent cholangitis and cholelithiasis. The diagnosis depends on both histology and imaging methods which can show the communication between the sacculi and the bile ducts. Treatment consists of symptomatic treatment of cholangitis attacks by antibiotics, some endoscopic, radiological and surgical drainage procedures and surgery. Liver transplantation seems the ultimate treatment for this disease. Prognosis is fairly good unless recurrent cholangitis and renal failure develops.
