A novel strategy for synthesizing (E)-1-((3-ethyl-2,4,4-trimethylcyclohex-2-enylidene)methyl-4-substituted benzenes from 1-(2,6,6-trimethylcyclohex-1-enyl)ethanol has been developed; the allylic alcohol was treated with PPh(3).HBr in methanol followed by aldehydes in the presence of a base and furnished the 1,3-dienes in moderate to good yields (79-86%).

A comparative randomized trial was made of two intrauterine contraceptive devices: Nova-T and MLCu375. The IUDs were used by 637 and 606 women, respectively, for one year, unless the device was removed earlier. The reasons for IUD removal were analyzed after one year using the life-table method. Statistically significant differences were found in expulsion and removal for bleeding and/or pain rates.
