Chronic Fatigue Following Acute Epstein-Barr Virus Infection in Adolescents
Fatigue SyndromeChronic1 moreChronic fatigue syndrome (CFS) is characterized by unexplained, disabling and long lasting fatigue, as well as pain, impaired memory, sleep difficulties and other symptoms. Epstein-Barr virus (EBV) infection might precipitate CFS. In this study, 200 adolescents undergoing acute EBV infection will be followed prospectively, and also compared with a group of healthy controls. The aim is twofold: To identify factors that predispose to chronic fatigue among adolescents with acute EBV infection To compare pathophysiological features of patients with acute EBV infection with a group of healthy controls. Possible risk factors for chronic fatigue 6 months after EBV-infection includes: Severity of the initial infection Immune responses characteristics Characteristics of the neuroendocrine stress response Cognitive functioning Emotional disturbances Genetics/ epigenetics of candidate genes Certain personality traits Critical life events

Emergency Department, Rapid Assessment for Sexually Transmitted Infection

Bacterial Colonization in Tracheostomized Patients With Neurological or Neuromuscular Disease
Infectious Disorder of TracheaRespiratory Tract Infections1 morePatients with neurological or neuromuscular diseases may need a long-term tracheostomy to improve their respiratory function. Bacterial flora and bacterial drug resistance in the respiratory tract have never been studied until then for this type of patient in spite of their frequent hospital stay, their regular exposition to antibiotics and their susceptibility to swallowing disorders due to their pathology. This study is based on a single tracheal aspirate within the 48 first hours of the patient stay for a ventilation check up beside any infectious context to describe the basal bacterial respiratory flora.
Specificity Study of Diagnostic for Early Detection of Dengue Infection
Infectious DiseasesThis study assesses the specificity of DENV Detect™ NS1 ELISA versus standard reference tests (e.g. PCR or viral culture) for dengue diagnosis in the US. DENV Detect™ NS1 ELISA serves as an aid in the clinical laboratory diagnosis of early stages of Dengue infection in patients with clinical symptoms consistent with Dengue infection. This test is intended to be used on sera obtained within the first 7 days of symptoms. DENV Detect™ NS1 ELISA and rapid test results (positive or negative) must be confirmed by testing with a reference standard test. This study will use archived, leftover human serum samples that have been sequentially collected from areas non-endemic for Dengue infection. Each specimen must have been collected within the first 7 days of symptoms, and must be accompanied by clinical data demonstrating that the individual had symptoms consistent with Dengue infection. The samples will have no personally identifiable information. ELISAs and reference tests will be performed by different operators who are laboratory staff members. These staff members, blinded to each other's results, will evaluate the samples from each method independently.
Sensitivity Study of Diagnostic for Detection of Chagas Infection
Infectious DiseasesThis study is a multi-site trial assessing the sensitivity of Chagas Detect™ Plus rapid test versus standard reference tests (e.g. IFA, IHA, RIPA) for Chagas diagnosis. The Chagas Detect™ Plus rapid test serves as an aid in the clinical laboratory diagnosis of Chagas infection in patients. This test is intended to be used on human whole blood or serum samples. Chagas Detect™ Plus results (positive or negative) must be confirmed by testing with a reference standard test. Subjects will be patients at clinical sites located in Chagas-endemic areas. After informed consent is obtained and the subject is screened for eligibility, 2 diagnostic samples will be collected. One is blood from finger prick, and the other is blood from venous puncture (drawn from vein in arm). Rapid tests and reference tests will be performed by different operators who are laboratory staff members. These staff members, blinded to each other's results, will evaluate the samples from each method independently.
Staphylokinase and ABO Group Phenotype: New Players in Staphylococcus Aureus Implant-associated...
Staphylococcal InfectionThe purpose of this study is to identify bacterial and/or clinical features involved in the pathogenesis of Staphylococcus aureus implant-associated infections (IAI). Materials & methods: In total, 57 IAI S. aureus and 31 nasal carriage (NC) S. aureus isolates were studied. Staphylococcus aureus genetic background was obtained by microarray analysis. Multilocus sequence typing was performed to determine clonal complexes (CC). Biofilm production was investigated by resazurin and crystal violet methods

S1119 Peruvian H. Pylori Water Contamination Study
Helicobacter Pylori InfectionThe objective of this study is to elucidate the role of drinking water derived from the public source in Lima, Peru and transmission of H. pylori infection using genotypic techniques.
