Recommendations for Care of the Asymptomatic Patient

We present a set of reasonable guidelines for the care of healthy, asymptomatic individuals based upon recommendations prepared by an Internal Medicine review committee of Henry Ford Hospital. There recommendations have four goals: to prevent disease, to detect disease in an asymptomatic and potentially curable state, to enhance the patient\u27s quality of life, and to help physicians teach patients good health habits. Recommendations are made for infectious diseases, cancer, metabolic diseases, neurosensory conditions like visual and hearing loss, and general health habits. Some recommendations are at variance with those of well recognized authorities and should be viewed only as a suggested protocol for the care of the asymptomatic patient. Results of ongoing studies may alter our understanding of some areas of controversy and mandate revision of these guidelines periodically

The Influence of Critical Care Medicine on the Development of the Specialty of Emergency Medicine: A Historical Perspective

: Through their largely concurrent development, the specialties of emergency medicine and critical care medicine have exerted a great deal of influence on each other. In this article, the authors trace the commonalities that emergency medicine and critical care medicine have shared and report on the historical relationship between the two specialties. As issues between emergency medicine and critical care medicine continue to emerge, the authors hope to inform the current discussion by bringing to light the controversies and questions that have been debated in the past.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71469/1/j.aem.2005.04.016.pd

Rapid Virological Diagnosis of Central Nervous System Infections by Use of a Multiplex Reverse Transcription-PCR DNA Microarray▿

Viruses are the main etiological cause of central nervous system (CNS) infections. A rapid molecular diagnosis is recommended to improve the therapeutic management of patients. The aim of this study was to evaluate the performances of a DNA microarray, the Clart Entherpex kit (Genomica, Coslada, Spain), allowing the rapid and simultaneous detection of 9 DNA and RNA neurotropic viruses: herpes simplex virus 1 (HSV-1), HSV-2, varicella-zoster virus (VZV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6), HHV-7, HHV-8, and the human enteroviruses (HEVs). This evaluation was performed with 28 samples from the European proficiency panels (Quality Control for Molecular Diagnostics [QCMD]; Glasgow, Scotland) and then with 78 cerebrospinal fluid (CSF) specimens. The majority of the QCMD results obtained by the DNA microarray were similar to those recorded by the overall QCMD participants. The main discrepant results were observed for low concentrations of HSV-2 and HEVs. From the clinical samples, the kit detected 27 of the 28 herpesvirus CNS infections and all of the 30 HEV-positive CSF samples. No false-positive result was observed among the 20 virus-negative CSF samples. The clinical sensitivity, specificity, and negative and positive predictive values of the assay were 98.3, 100, 95.2, and 100%, respectively, when the results were compared to those of commercially available PCR assays. Interestingly, HHV-7 was detected in 11 (37%) of the 30 HEV-positive CSF samples from children suffering from aseptic meningitis causing significantly longer lengths of stay at the hospital than infection with HEVs alone (2.4 versus 1.4 days; P = 0.038). In conclusion, this preliminary study showed that this DNA microarray could be a valuable molecular diagnostic tool for single and mixed DNA and RNA virus infections of the CNS
