Focal epilepsy as a long term sequela of Parvovirus B19 encephalitis.

Human Parvovirus B19 (PVB19), the etiological agent of the fifth disease, is associated with a large spectrum of pathologies, among which is encephalitis. Since it has been detected from the central nervous system in children or in immunocompromised patients, its causative role in serious neurological manifestations is still unclear. Here we report the case of an 18-year-old healthy boy who developed encephalitis complicated by prolonged status epilepticus.

Fatal pulmonary disease and encephalic complication in a man with HSV-1 Infection: a case report.

Herpes simplex virus type 1 (HSV-1) is associated with a large spectrum of pathologies i.e. pulmonary diseases.

Detection of serum IgA to HSV1 and its diagnostic role in sudden hearing loss.

A viral etiology of sudden hearing loss has been hypothesized by many authors. HSV1 neurotropism and its involvement in sudden hearing loss has implicated HSV1 as one of the most accredited etiological agents. A non-invasive method such as the titration of HSV1-specific IgA was evaluated to determine the role of HSV1 as a possible cause sudden hearing loss.

Synergy of molecular and serological methods in minimally invasive diagnosis of enteroviral cardiac infection.

Treatment of myocarditis and pericarditis can differ on the basis of aetiology: systemic or auto-immune disease can be positively influenced by corticoid therapy, whereas this kind of treatment can worsen the course of virus-induced disease. Therefore, the aetiological diagnosis is extremely important. The synergistic use of minimally invasive serological, IgG, IgM, IgA, and neutralizing titres, and RNA detection was evaluated on representative patients out of 238 suffering from cardiopathies.

[Clinical, virological and epidemiological aspects of acute B hepatitis in the Catania area (Italy)].

Starting from January 1997 we prospectively evaluated all cases of acute hepatitis B admitted to two of the main Infectious Diseases Units in Catania (eastern Sicily). The survey was extended throughout a 10-year period up to December 2007. Between 1997 and 1999 we observed 21 cases of acute hepatitis B; between 2000 and 2002 18 cases; between 2003 and 2005 22 cases and, finally, 37 cases were reported in the period 2006-2007.
