[Actinomycosis--a multidisciplinary approach to a clinical problem].

Actinomycosis is caused by microorganisms of the Actinomyces species, found in the oral cavity, gastrointestinal and genital tract. Infection by Actimomyces species mainly causes chronic supurative disease of the oral, cervico-facial, thoracic, and abdominal regions. Clinical manifestations have been described at every level, but the disease is relatively rarely diagnosed.

[Fulminant hepatitis B].

Fulminant hepatitis, or fulminant hepatic failure, is defined as a clinical syndrome of severe liver function impairment, which causes hepatic coma and the decrease in synthesizing capacity of liver, and develops within eight weeks of the onset of hepatitis. Several independent factors influence the survival of patients: age, the cause of liver disease, the degree and the duration of encephalopathy in relation to the onset of the disease, and the prevention of complications. Over the years many intensive treatments have been practiced.
