The high incidence and debilitating effects of lymphedema must be weighed against the benefits of PMRT. Efforts to prevent lymphedema should be emphasized.

Evidence for a male-produced aggregation pheromone inSitophilus granarius is reported. Hexane extracts of Tenax®-trapped volatiles from males held on wheat were attractive to both sexes in a multiple-choice olfactometer and pitfall bioassay chamber. A quantitative relationship existed between days of insect exposure on disks and degree of responsiveness. The maximum response was to 35 insect-day-equivalents. Diel-related activity showed both sexes responsive during photophase and nonresponsive during scotophase.

The incidence of PPS recurrences is substantial in advanced-stage soft-palate cancer. PPS recurrences negatively impact survival; without effective salvage techniques for these recurrences or effective adjuvant therapy, poor patient outcomes can be expected.
