The light curves and amplitude spectra were obtained following a classical scheme of multichannel photometry. Observations in different filters were also obtained and analyzed. Six and three frequencies have been unambiguously detected above a 99% confidence level in the range 190-300 muHz and 100-145 muHz in 7 Aql and 8 Aql, respectively. A comparison of observed and theoretical frequencies shows that 7 Aql and 8 Aql may oscillate with p-modes of low radial orders, typical among delta Scuti stars. In terms of radial oscillations the range of 8 Aql goes from n=1 to 3, while for 7 Aql the range spans from n=4 to 7. Nonradial oscillations have to be present in both stars as well. The expected range of excited modes according to a nonadiabatic analysis goes from n=1 to 6 in both stars.

[more ▼] We report 2 cases of primary systemic amyloidosis. A monoclonal gammopathy was confirmed at the postmortem examination of the first patient. An extensive search for evidence of chronic infection, inflammation, neoplasms and paraproteinemia was conclusively negative in the other patient. The recognition of cutaneous signs of primary systemic amyloidosis is crucial to insure a rapid management aimed at postponing the fatal issue of the disease.
