    (Professional Medical Publications, 2010) Cengiz, Tas Z.; Yilmaz, Hasan; Akdeniz, Necmettin; Cicek, Mutalip; Ozkol, Halil; Calka, Oemer
    Objectives: Demodex spp of humans are encountered frequently all over the world. The role of these parasites is controversial in the causation of skin diseases. This study was carried out to determine the prevalence and the association of Demodex spp with acne rosacea. Methodology: The study was conducted between the years of 2005-2008 in the output clinic of Dermatology and Parasitology Laboratory of Health Research and Training Hospital of Yuzuncu Yil University. One hundred two patients (patient group) composing of 59 females and 43 males with acne rosacea and randomly selected 50 healthy subjects (control group) were examined for Demodex spp. Twenty seven patients were under the age of 35, and 75 patients were aging 35 years old and over. Samples were plucked out from surface of nose and forehead of patients with acne rosacea and healthy subjects by standardized surface skin biopsy (SSSB) method in the Laboratory. The preparations prepared in Hoyer solution were examined under 4X and 10X objectives of light microscope. Results: The detected parasites were higher in the patient group with acne rosacea (67.65%) than the control group (6%), in females (76.27%) than males (55.81%) and in patients aging 35 years old and over (74.67%) than the patients under 35 years of age (48.15%). Significant relationships were detected between acne rosacea and demodicosis, sex and demodicosis, and age and demodicosis (p<0.001, p<0.05 and p<0.05, respectively). Conclusion: It was concluded that there is a relationship between the demodicosis and acne rosacea, and dermatologists should take into consideration the Demodex spp. in the etiology of acne rosacea.

    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.

    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.
