We collected acute-phase and convalescent-phase serum samples from Brazilian patients who presented with exanthem of unknown origin and evaluated these samples by means of an immunoblot assay for seroconversion to human herpesvirus 6 (HIV-6) or human herpesvirus 7 (HIV-7). Measles or rubella had been clinically diagnosed in all these patients, but their sera were negative for antibodies to both...

Patients who receive stem cell transplantation (SCT) can develop cutaneous eruptions with systemic involvement such as graft versus host disease (GVHD), drug hypersensitivity syndrome (DIHS), or viral exanthema. These conditions often have overlapping clinical and laboratory presentations may be associated risk factors reactivation medications. In this study, we evaluated the incidence, present...

CVA6: Coxsackievirus A6 CVA16: Coxsackievirus A16 EC: eczema coxsackium EV: enterovirus EM: erythema multiforme GVHD: graft-versus-host disease HFMD: hand, foot, and mouth disease HSV: herpes simplex virus RT-PCR: reverse transcriptase polymerase chain reaction SJS: Stevens-Johnson syndrome INTRODUCTION Hand, foot, and mouth disease (HFMD) is a common, self-limited viral exanthem characterized ...

A healthy 22-year-old man developed acute varicella pericarditis, characterised by an enanthem with diagnostic rising titres of varicella zoster antibodies but without the typical exanthem. This, the third reported case of varicella pericarditis, is the first to be documented without a typical varicella eruption.

Human herpesvirus 6 (HHV-6) DNA was detected in peripheral blood from exanthem subitum patients during the acute and convalescent phases of infection using the polymerase chain reaction. Although DNA could be detected in non-adherent and adherent mononuclear cells during the acute phase, it was detected predominantly in adherent cells during the convalescent phase; furthermore, viral DNA was fo...
