CONTEXT The novel influenza A(H1N1) pandemic affected Australia and New Zealand during the 2009 southern hemisphere winter. It caused an epidemic of critical illness and some patients developed severe acute respiratory distress syndrome (ARDS) and were treated with extracorporeal membrane oxygenation (ECMO). OBJECTIVES To describe the characteristics of(More)
The presence of microorganisms in a patient's blood is a critical determinant of the severity of the patient's illness. Equally important, the laboratory isolation and identification of a microorganism present in blood determine the etiologic agent of infection, especially when the site of infection is localized and difficult to access. This review(More)
In the coming decades, cancer will be a major clinical and public health issue in sub-Saharan Africa. However, clinical and public health infrastructure and services in many countries are not positioned to deal with the growing cancer burden. Pathology is a core service required to serve many needs related to cancer in sub-Saharan Africa. Cancer diagnosis,(More)
BacT/Alert (Organon Teknika Corp., Durham, N.C.) is an automated microbial detection system based on the colorimetric detection of CO2 produced by growing microorganisms. Results of an evaluation of the media, sensor, detection system, and detection algorithm indicate that the system reliably grows and detects a wide variety of bacteria and fungi. Results(More)
OBJECTIVE To evaluate the impact of active screening for methicillin-resistant Staphylococcus aureus (MRSA) on MRSA infection rates and cost avoidance in units where the risk of MRSA transmission is high. METHODS During a 15-month period, all patients admitted to our adult medical and surgical intensive care units (ICUs) were screened for MRSA nasal(More)
We investigated correlates for suicidal expression among adolescents in the Seychelles. Data on 1,432 students (52% females) were derived from the Global School-based Health Survey. Participants were divided into three groups: those with no suicidal behavior (N = 1,199); those with suicide ideation/SI (N = 89); and those reporting SI with a plan to carry(More)
In an era characterized by increasing emphasis on minimizing laboratory costs, reliable and cost-effective methods for rapidly identifying bacteria and fungi directly from blood cultures have a great deal of appeal to clinical microbiologists. A variety of methods have been evaluated and found to be useful under certain conditions, although none of the(More)
The objective of this study was to identify the incidence of burn injuries among children in a sub-Saharan urban area and describe contributing factors in the home environment. A cross-sectional household survey was conducted in Dar es Salaam, Tanzania between 8 and 22 July 2009. Demographic characteristics of participants were reported using descriptive(More)
CONTEXT False-positive cultures for Mycobacterium tuberculosis have been found in nearly all DNA fingerprinting studies, but the effectiveness of interventions to reduce cross-contamination has not been evaluated. OBJECTIVE To evaluate whether changes in laboratory policies and procedures reduced the rate of false-positive cultures. DESIGN Retrospective(More)
Hepatitis C virus (HCV) infection is gaining increasing attention as a global health crisis. Egypt reports the highest prevalence of HCV worldwide, ranging from 6% to more than 40% among regions and demographic groups. Predicting the impact of the epidemic has been difficult because of the long-latency period and low-resource setting. Accordingly, we sought(More)
