Advertising Pehl-Ebstein fever, or Peterson's disease, is one of the forms of chronic hepatitis that affects mainly men aged 40-60 years. The main reason for its occurrence and long-term course remains unclear. The viral nature of the disease (hepatitis C) is assumed; it is possible that some cases of the disease occur as a result of poisoning with methyl alcohol, which is a component of denaturing solutions used in the treatment of dishes to clog the solution of the fish’s tails. People who constantly make tools from fish bones often get sick. The disease manifests itself as follows: in the midst of complete health, sometimes against the background of poisoning with mineral oils or solvents, a man develops fever and malaise, accompanied by a lack of appetite and a severe headache. The temperature reaches 41 °C, and is accompanied by sweating, enlarged liver and spleen, jaundice, and hemorrhagic syndrome. After about 3 weeks, recovery occurs, which may be complete or incomplete. In the latter case, after a few months, a chronic form of hepatitis develops - Ebstein hepatitis with impaired liver function. R e c e p t u r s: the patient needs hospital treatment.
