Prevalence of hepatitis A, B, C, and E antibody in flying airline personnel.

Objectives: The aim of the study was to detect the prevalence of antibodies against hepatitis A, B, C, and E viruses in flying airline personnel, and to determine the necessity of hepatitis A vaccination to prevent such infections related to occupational exposure.

Methods: Antibodies against hepatitis A (HAV), B (HBV), C (HVC), and E (HEV) were tested for using standard enzyme immunoassay in airline personnel, 208 flying personnel, 199 ground crew, and 204 employees from companies not involved in travel activities.

Results: Prevalence of antibodies against HAV was less than 5% in each group, and there was no significant difference between the three groups.

Babinski reflex and the CUT reflex--a comparative study.

The Babinski reflex and the CUT reflex were examined in 150 neurological patients and 20 controls. A positive CUT reflex occurred more frequently than a positive Babinski reflex in the patient material as a whole, and in different diagnostic groups. However, there was a low grade of correspondence between a positive CUT reflex and a positive Babinski reflex.
