The serum squamous cell carcinoma antigen level in inverted sinonasal papilloma and nasal polyps patients.

Objective: To clarify whether the serum squamous cell carcinoma antigen (SCCA) levels of patients with inverted papilloma (IP) are different from patients with nasal polyps (NP) and rhinitis.

Materials And Methods: Serum SCCA levels were measured in 30 patients with IP and 30 patients with NP at one day before surgery and seven days after surgery and measured in 28 patients with rhinitis.

Results: Elevated serum SCCA levels (>1.

Risk of chikungunya virus transmission associated with European travelers returning from southern Thailand (2008-2015).

Background: The impact of the spread of chikungunya virus (CHIKV) by autochthonous transmission and blood transfusion in nonendemic areas via travelers returning from CHIKV-affected locations is a concern.

Methods: We analyzed the risks of potential CHIKV importation and transfusion transmission from Thailand to Europe via travelers visiting southern Thailand from 2008 through 2015, using the web-based European Up-front Risk Assessment Tool.

Results: The risk of CHIKV importation by European travelers returning from Thailand from 2008 through 2015 varied depending on the year of travel, tourist destination, duration of stay, and time since last possible exposure.

Risk of transfusion-transmitted chikungunya infection and efficacy of blood safety implementation measures: experience from the 2009 epidemic in Songkhla Province, Thailand.

Background: To date, neither is there a standard guideline for maintaining a safe blood supply during a chikungunya fever (CHIKF) outbreak nor has a study been performed on actual transfusion-transmitted CHIKF to recipients. This study estimated the potential incidence of transfusion-transmitted CHIKF and compared the efficacies of various blood safety intervention strategies to mitigate the transfusion-transmitted CHIKF risk.

Study Design And Methods: A Web-based tool named the European Up-Front Risk Assessment Tool (EUFRAT) was used to estimate the risk of transfusion-transmitted CHIKF using data inputs from the 2009 Songkhla epidemic in Thailand.

Viremic profiles in asymptomatic and symptomatic chikungunya fever: a blood transfusion threat?

Background: The presence of a chikungunya virus (CHIKV) outbreak could have an impact on transfusion safety when there are a large number of infected persons during an epidemic. Serosurveys have found that 3% to 28% of infected persons remain asymptomatic and are potential disseminators of transfusion-associated chikungunya. However, the viremic profiles of asymptomatic chikungunya patients, the major determinant of the transfusion risk, are unknown.

A prospective evaluation of four immunodiagnotic assays for human leptospirosis.

This was a prospective evaluation of four immunodiagnostic assays for human leptospirosis, including the indirect immunofluorescence test (IFA), the microscopic agglutination test (MAT), the LEPTO dipstick, and the latex agglutination (LA) test. Four hundred ninety-two serum samples were collected from 348 patients who presented with acute fever without localizing signs. The sensitivities of the IFA, MAT, Dipstick, and LA were 91.
