Alcohol-induced pain in tuberculous adenitis.

Since its first description in Hodgkin's disease, alcohol-induced pain has subsequently been described both in other neoplasms and in various non-malignant conditions. There seems little doubt that ethyl alcohol itself is responsible, although the mechanism for producing pain remains elusive. We report a case of alcohol-induced pain in a patient with enlarged lymph nodes on the right side of the neck.

Increased reactivity of laminin in the basement membranes of capillary walls in AIDS brain cortex.

To verify how the components of the capillary wall are modified in the course of AIDS we studied the brain cortex from nine cases with AIDS. Cellular and extracellular components were delineated using antibodies for laminin and collagen IV for basement membranes and glial fibrillary acidic protein for astrocyte foot processes. We found a marked increase in reactivity for laminin in the basement membranes of capillary walls and hypertrophy and hyperplasia of astrocyte foot processes around vessels, when compared to control cortical tissue.
