    Human infection with Dicrocoelium dendriticum in Turkey
    (K Faisal Spec Hosp Res Centre, 2010) Cengiz, Zeynep Tas; Yilmaz, Hasan; Dulger, Ahmet Cumhur; Cicek, Mutalip
    Human dicrocoeliosis is reported sporadically in various parts of the world. We report a case in a 21-year-old male, who had right upper abdominal pain, weight loss, and chronic relapsing watery diarrhea three to four times daily for four weeks. The patient had abdominal tenderness to palpation in the right upper quadrant. Alkaline phosphatase, alanine aminotransferase, and serum immunoglobulin E levels were slightly elevated; all other biochemical and hematological findings were in their normal ranges. The duodenal biopsy samples were normal and an abdominal ultrasonography showed no biliary or hepatic abnormality. Stool microscopy revealed numerous eggs of Dicrocoelium dendriticum. As pseudoparasitosis can result from eating raw, infected animal liver, the patient was given a liver-free diet for three days, to rule out that possibility. Subsequent stool examinations showed eggs in each of the samples indicating that the infection was genuine. The patient was treated with triclabendazole 10 mg/kg in a single dose. Four weeks later, no parasite eggs were detected in the microscopic examination of the stool samples. The patient got better gradually and the symptoms disappeared. Physicians should keep in mind parasitic diseases such as the rarely encountered dicrocoeliosis.

    Multicenter Epidemiologic Study on Hepatocellular Carcinoma in Turkey
    (Asian Pacific Organization Cancer Prevention, 2014) Can, Alper; Dogan, Erkan; Bayoglu, Ibrahim Vedat; Tatli, Ali Murat; Besiroglu, Mehmet; Kocer, Murat; Dulger, Ahmet Cumhur
    Background: Hepatocellular cancer (HCC) is one of the important health problems in Turkey, being very common and highly lethal. The aim of this study was to determine clinical, demographic features and risk factors. Materials and Methods: Nine hundred and sixth-three patients with HCC from 13 cities in Turkey were included in this study. Results: Only 205 (21%) of the 963 patients were women, with a male: female predominance of 4.8:1 and a median age of 61 years. The etiologic risk factors for HCC were hepatitis B in 555 patients (57.6%), 453 (81%) in men, and 102 (19%) in women, again with male predominance, hepatitis C in 159 (16.5%), (14.9% and 22.4%, with a higher incidence in women), and chronic alcohol abuse (more than ten years) in 137 (14.2%) (16.8% and 4.9%, higher in males). The Child-Pugh score paralleled with advanced disease stage amd also a high level of AFP. Conclusions: According to our findings the viral etiology (hepatitis B and hepatitis C infections) in the Turkish population was the most important factor in HCC development, with alcohol abuse as the third risk factor. The Child-Pugh classification and AFP levels were determined to be important prognostic factors in HCC patients.

    Seroprevalence of human fascioliasis in Van province, Turkey
    (Aves, 2015) Cengiz, Zeynep Tas; Yilmaz, Hasan; Dulger, Ahmet Cumhur; Akdeniz, Hayrettin; Karahocagil, Mustafa Kasim; Cecek, Mutalip
    Background/Aims: Fasciola hepatica is a rare zoonotic parasite that infects the liver of many mammals including humans. The aim of this study was to determine the seroprevalence of fascioliasis in Van province by ELISA (antibody detection) on the assumption that not all cases could be detected by stool examination alone. Materials and Methods: A total of randomly selected 1,600 patients, directed from affiliated outpatient clinics to Yuzuncu Yil University Medical Faculty Parasitology Laboratory, were enrolled in the study. Their mean age was 4.44 +/- 19.00 years. Blood samples were collected from all the patients, and their stool samples were examined. For the stool examination, native-lugol and sedimentation (in formalin-ethyl acetate) methods were employed. ELISA for F. hepatica was performed on the blood samples from all patients. Seropositive patients were treated with triclabendazole. Results: F. hepatica was detected by ELISA in 89 (5.6%) of the 1,600 patients, but eggs were identified on the stool examination in only 29 (1.8%) patients. The prevalence of F. hepatica was higher in females (7.2%) than in males (4.2%) and was higher in the >= 36-year age group (6.7%) than in the <= 35-year age group (4.4%). Abdominal pain (93.3%), fatigue (88.8%), and weight loss (69.7%) were the most common symptoms. Eosinophilia was present in 89.9% of the patients. All seropositive patients had a history of eating raw aquatic plants. Conclusion: Stool examination alone is not sufficient to diagnose F. hepatica. Serological tests such as ELISA must be used together with stool examination.
