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 .
Retreatment with nafarelin for recurrent endometriosis symptoms: efficacy, safety, and bone mineral density.
OBJECTIVE To assess the efficacy , safety , and effect on bone mineral density of a 3-month course of retreatment with intranasal nafarelin acetate for recurrent symptoms of endometriosis . DESIGN Multicenter , open-label , nonr and omized clinical trial . SETTING Eleven hospital-based and private practice s. PATIENT(S ) Thirty-six women with endometriosis symptoms recurring after 3 or 6 months of treatment with nafarelin .  INTERVENTION(S ) Nasal nafarelin 200 micrograms twice daily for 3 months . MAIN OUTCOME MEASURE(S ) Assessment s for dysmenorrhea , dyspareunia , pelvic pain , tenderness , and in duration . Measurement of bone mineral density of the lumbar spine . RESULT ( S ) Improvements from admission to the end of retreatment were significant for dysmenorrhea , pelvic pain , tenderness , in duration , and dyspareunia . Three months after retreatment ended , mean symptom scores for dysmenorrhea and pelvic tenderness , although worse than at the end of retreatment , were still significantly better than scores at admission . Mean bone mineral density 3 months after retreatment was 0.56 % lower than before retreatment and 1.94 % lower than before initial treatment . CONCLUSION ( S ) Three-month nafarelin retreatment for recurrent endometriosis symptoms was effective and safe
