Drug reactions (DR) are adverse or harmful effects of drugs. They constitute 6.5% of all hospital admissions. DR develops with a rate of 15% in patients who are treated by hospitalization. The possibility of DR should be considered in the differential diagnosis when any medical problem occurs in a person who uses medication. Detailed history and physical examination are directive in differentia...

A 5 month old girl had typical clinical features of acute myocarditis just after the febrile period of exanthem subitum and died immediately. She had been healthy, with normal development, and there was no family history of particular note. Myocardial postmortem findings were compatible with acute myocarditis. Although the isolation of human herpesvirus 6 (HHV-6) was not attempted, positive IgM...

INTRODUCTION Kawasaki disease is an acute systemic vasculitis of childhood, of unknown origin, and is considered the leading cause of acquired heart disease in children. Therefore, it is important to know clinical manifestations and complications in children with Kawasaki disease in our environment and to look for risk factors for the development of cardiac complications. MATERIAL AND METHODS...

BACKGROUND Skin biopsies are commonly performed to confirm drug-induced exanthem (DIE). However, the relevance of histologic examination in discriminating between DIE and non-DIE (NDIE) is controversial. OBJECTIVE A retrospective analysis was performed to evaluate the reliability of histologic diagnosis of DIE. METHODS In all, 91 patients with a skin biopsy specimen of an acute exanthem tem...

Autophagy has been intensively studied in herpes simplex virus type 1 (HSV-1), a human alphaherpesvirus. The HSV-1 genome encodes a well-known neurovirulence protein called ICP34.5. When the gene encoding this protein is deleted from the genome, the virus is markedly less virulent when injected into the brains of animal models. Subsequent characterization of ICP34.5 established that the neurovi...

Infections with human herpesvirus 6 (HHV-6), a beta-herpesvirus of which two variant groups (A and B) are recognized, is very common, approaching 100% in seroprevalence. Primary infection with HHV-6B causes roseola infantum or exanthem subitum, a common childhood disease that resolves spontaneously. After primary infection, the virus replicates in the salivary glands and is shed in saliva, the ...

INTRODUCTION Exanthem subitum is a classical rash disease of early childhood caused by human herpesvirus 6B (HHV-6B). However, the rash is frequently misdiagnosed as that of either measles or rubella. METHODS In this study, a nested multiplex polymerase chain reaction (PCR) was used to diagnose HHV-6B primary infection, differentiate it from infections caused by HHV-6A and compare it to antib...
