The generally warm, moist environmental conditions in the Northwestern Iran are ideal for survival and growth of the egg and larval stages of Haemonchus contortus and other gastrointestinal nematodes (GIN) of sheep and goats.A total of 2,421 animals were slaughtered and examined from July 2010 to July 2011 in Urmia abattoir. In case of sheep, 225 out of 2,421 were positive and prevalence of H. contortus infestation was 9.3 %. Sex wise prevalence of H. contortus in sheep was 33.08 % (76/229) in male and 66.22 % (149/225) in female. The females indicated significantly (P < 0.05) higher prevalence (66.22 %) as compared to males (33.08 %). The highest prevalence was recorded in the spring (April) and the lowest was in summer (July), respectively. On microscopic examination, infiltration of mononuclear cells and eosinophils in gastric glands, periglandular hyperemia and hemorrhage, mucous gland hyperplasia, connective tissue proliferation and necrosis was observed. Also, in mixed abomasal infection with Haemonchus and Ostertagia species, mucosal hyperplasia and increased mucous glands and sometimes cystic glands were seen. Statistical analysis using SPSS software, and Chi-square test, demonstrated a non-significant difference between ages and abomasal PH values of infected and healthy sheep (P < 0.05). But the difference between sexes, seasons and abomasal lesions was significant (P > 0.05).
Introduction: Provision of unnecessary medical services is one of the problems that have driven up health care budgets. The condition of Emergency department and sometimes patients 'unreasonable expectations may lead to ED staff burnout and increase the provision of unnecessary services.
Methods: In this study, the Hospital Urgencies Appropriateness Protocol (HUAP) was used to assess the appropriateness of services provided in the ED. The sample size of this study consisted of 445 patients who were selected among the patients admitted in Rasoul Akram and Firouzgar hospitals by stratified sampling. Chi-square and logistic regression tests were used to analyze the data.
Results: The rate of inappropriate admission in the ED of the studied hospitals was measured at about 13%. Patients admitted to the Firouzgar ED showed a higher probability to inappropriate admission. Among considered factors, gender and Interval between the onset of symptoms and ED admission are affecting factor in inappropriate admission.
Conclusion: The rate of in appropriate admission is somehow high in this study. Gender and Interval between the onset of symptoms and ED admission can be considered as predictors of the provision of unnecessary services. So it is significant to provide operational and evidence-based solutions regarding the issues related to the provision of unnecessary services in the ED.
Parasitic diseases of wild birds follows its companion volume, infectious diseases of wild birds, both of which complement the third edition of infectious diseases of wild mammals and second edition of parasitic diseases of wild mammals. In October 2012, a mature black male mynah with lack of balance and ataxia was brought into the birds department of educational hospital in veterinary medicine faculty of Tehran University. Because of no cure in clinical signs after several days of empirical therapy euthanasia and clinical pathology studies were performed. There was no microscopic pathological lesions in brain, bone marrow, heart, lung, liver and the microscopic results were as following; bone marrow: hemophagocytosis reactive macrophages, liver: infiltration of inflammatory cells (hepatitis) and hemosiderin-laden macrophages. Lung: hemosiderin-laden macrophages and spleen findings: infiltration of inflammatory cells, heterophils with phagocytic bacteria. In abdominal cavity two male and one female parasite was detect. Three parasites were cleared with lactophenol and investigated under the light microscopy and important morphological parts of them measured. Also these parasites in serum containing send to the department of parasitology. Based on all collecting data, Spinodiplotriaena (three parasites each by the length of 2/5, 1/7 and 1/5 cm were found) were diagnosed. Report of this case in important because of first report of this infection in a black mynah in Iran.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
