background: celiac disease is one of the malabsorption syndromes leads to growth and development retardation in children. there is no test lonely can definitely diagnose celiac; however, the collection of clinical findings, serologic tests, intestinal biopsy, and response to treatment may diagnose it. although diagnostic value is variable in different studies, they are used a non-invasive and a...

1. the most important challenge in diagnosis of celiac disease is not-performing the diagnostic tests in suspected persons. because of multi-organ damage and multiple manifestations of disease, diagnosis of celiac disease may be delayed. it seems general physicians should be aware about uncommon presentations of disease and indications of celiac tests. 2. the second most important challenge is ...

Between 2002 and 2006 in the Department of Tropical and Parasitic Diseases of the Medical University of Gdansk 40 hospitalized patients were suspected of schistosomiasis on the basis of clinical manifestations, epidemiological data and positive serology tests (ELISA IgG). In spite of multiple tests, schistosoma eggs were not identified neither in stool nor in urine of the patients. Histopatholo...

BACKGROUND The direct agglutination test (DAT) has proved to be a very important sero-diagnostic tool combining high levels of intrinsic validity and ease of performance. Otherwise, fast agglutination screening test (FAST) utilises only one serum dilution making the test very suitable for the screening of large populations. RESULTS We have tested FAST and DAT for the detection anti-Leishmania...

A latex agglutination test was evaluated as a method for detection and titration of antiplague antibodies. Slide and microtiter techniques using polystyrene latex particles coated with specific fraction-I-antigen of Yersinia pestis were found to be comparable in specificity and sensitivity to serological tests commonly used in laboratory practice. The latex agglutination titers correlated well ...

This systematic review addresses 2 questions pertinent to the need for pretreatment liver biopsy in patients with chronic hepatitis C: how well do liver biopsy results predict treatment outcomes for chronic hepatitis C? How well do biochemical blood tests and serologic measures of fibrosis predict the biopsy findings in chronic hepatitis C? Medline and other electronic databases were searched f...

To the Editor: Accumulating evidence suggests that the degree of serologic crossreactivity to pandemic (H1N1) 2009 virus varies between populations worldwide. To assess potential serologic cross-reactivity in Singapore, we obtained serum samples during May–June 2009 from 50 randomly recruited, healthy volunteers born mostly before 1958 (i.e., potentially those with some natural exposure to the ...

A herpesvirus was isolated from the liver of a captive-bred American kestrel (Falco sparverius) which had died of inclusion body disease. Initial isolation was achieved in chicken embryo fibroblasts after three blind passages. Cell-adapted virus produced a distinct rounding of CEF cells within 24 to 48 h. Biologic and serologic tests suggested that the kestrel virus is similar to falcon herpesv...

The problems of diagnosis and treatment of Lyme neuroborreliosis can be minimised by strictly following the clinical diagnostic criteria, and understanding the pitfalls of laboratory tests. The diagnosis is based solely on objective clinical findings, with serologic test results used only to confirm the diagnosis. It must be underscored that serologic testing, when ordered without regard for cl...

OBJECTIVES To conduct a study in a small rural hospital located in the state of Chiapas, Mexico, to: (1) examine the prevalence of chagasic cardiomyopathy among patients with the diagnosis of congestive heart failure and (2) assess the prevalence of positive serologic results in blood donors in the hospital, in an attempt to ascertain whether Chagas' disease remains an important cause of heart ...
