RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score , while multidimensional inventories were used in few studies .
The results of clinical studies in CPP are more frequently based on one-dimensional measurements .
RATIONALE Many types of  pain assessment are available to research ers carrying out clinical trials in chronic pelvic pain ( CPP ) , ranging from a single-item scale to multidimensional inventories .
AIM Our objective was to investigate which assessment s of pain are more commonly used in clinical trials on CPP .
Use of a progestogen only preparation containing desogestrel in the treatment of recurrent pelvic pain after conservative surgery for endometriosis.
OBJECTIVE To assess the effect of a new progestin progestogen only pill ( desogestrel ) versus an oral contraceptive in the treatment of recurrent endometriosis . STUDY DESIGN A r and omized prospect i ve clinical study . A group of women with endometriosis ( n=40 ) who showed recurrent dysmenorrhea and /or pelvic pain after conservative surgery , and did not desire a pregnancy . Continuous treatment for 6 months with desogestrel ( 75 microg/d ) ( n=20 ) versus a combined oral contraceptive ( ethinyl estradiol 20 microg plus desogestrel 150 microg ) ( n=20 ) was performed . RESULTS A significant improvement of both pelvic pain and dysmenorrhea was observed following each type of treatment ( P<0.001 ) . The use of desogestrel progestogen only pill was associated with a breakthrough bleeding in 20 % patients , while a significant body weight increase was observed in 15 % after oral contraceptive . CONCLUSIONS Both desogestrel and an oral estro-progestinic were effective , safe and low cost therapy of pain symptoms after endoscopic surgery for endometriosis , the former showing an impact on breakthrough bleeding , the later an incidence on body weight increase
