Identification of a novel coronavirus in patients with severe acute respiratory syndrome
BACKGROUND: The severe acute respiratory syndrome (SARS) has recently been identified as a new clinical entity. SARS is thought to be caused by an unknown infectious agent. METHODS: Clinical specimens from patients with SARS were searched for unknown viruses with the use of cell cultures and molecular techniques. RESULTS: A novel coronavirus was identified in patients with SARS. The virus was isolated in cell culture, and a sequence 300 nucleotides in length was obtained by a polymerase-chain-reaction (PCR)-based random-amplification procedure. Genetic characterization indicated that the virus is only distantly related to known coronaviruses (identical in 50 to 60 percent of the nucleotide sequence). On the basis of the obtained sequence, conventional and real-time PCR assays for specific and sensitive detection of the novel virus were established. Virus was detected in a variety of clinical specimens from patients with SARS but not in controls. High concentrations of viral RNA of up to 100 million molecules per milliliter were found in sputum. Viral RNA was also detected at extremely low concentrations in plasma during the acute phase and in feces during the late convalescent phase. Infected patients showed seroconversion on the Vero cells in which the virus was isolated. CONCLUSIONS: The novel coronavirus might have a role

Diagnostics and treatment of HIV-discordant couples who wish to have children.
Over the last years the reality surrounding HIV-infection has undergone a considerable change with regard to the life expectancy of patients, and the plans they can make for their lives. Because the majority of the HIV positive population is of reproductive age, one of these plans might be to have children, often as an expression of a fulfilled partnership. The need for medical support to realize this wish, however, is often confronted with ethical, medical or forensic restraints. For this reason, interdisciplinary recommendations have now been developed--for the first time on a global basis--which aim to provide guidelines for practitioners in this complicated area
