Cyclosporiasis outbreak, Indonesia.

We describe an outbreak of Cyclospora cayetanensis infection among Dutch participants at a scientific meeting in September 2001 in Bogor, Indonesia. Fifty percent of the investigated participants were positive for C. cayetanensis.

Clinical pulmonary infection score for ventilator-associated pneumonia: accuracy and inter-observer variability.

Objective: Although quantitative microbiological cultures of samples obtained by bronchoscopy are considered the most specific tool for diagnosing ventilator-associated pneumonia, this labor-intensive invasive technique is not widely used. The Clinical Pulmonary Infection Score (CPIS), a diagnostic algorithm that relies on easily available clinical, radiographic, and microbiological criteria, could be an attractive alternative for diagnosing ventilator-associated pneumonia. Initially, the CPIS scoring system was validated upon 40 quantitative cultures of bronchoalveolar lavage fluid from 28 patients, and only few other studies have evaluated this scoring system since then.

Influence of cytomegalovirus seropositivity on outcome after T cell-depleted bone marrow transplantation: contrasting results between recipients of grafts from related and unrelated donors.

We analyzed the effect of cytomegalovirus (CMV) serostatus on overall survival (OS) and transplant-related mortality (TRM) in 253 consecutively treated patients receiving partially T cell-depleted (TCD) bone marrow from either matched related donors (MRDs; n=205) or matched unrelated donors (MUDs; n=48). Short-course, low-dose preemptive therapy with ganciclovir was provided as soon as a positive antigenemia assay result was obtained. Ganciclovir prophylaxis, which was identical to preemptive therapy, was given to patients with acute graft-versus-host disease (GVHD) grades II-IV who had to be treated with high-dose steroids.

Polymerase chain reaction is more sensitive than viral culture and antigen testing for the detection of respiratory viruses in adults with hematological cancer and pneumonia.

We retrospectively analyzed the value of polymerase chain reaction (PCR) for the detection of respiratory viral infections in 43 patients with hematological cancer whose bronchoalveolar lavage (BAL) samples had been stored. In addition, 17 nose-throat (NT) swabs and 29 blood samples had been obtained. PCR was performed to detect parainfluenza viruses 1-3, respiratory syncytial virus, rhinovirus, influenza viruses A and B, enteroviruses, and coronaviruses.
