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 .
Safety and dose flexibility clinical evaluation of intravesical liposome in patients with interstitial cystitis or painful bladder syndrome.
To present single institution open-label experience with intravesical liposomes ( LPs ) , a mucosal protective agent , in patients with interstitial cystitis/painful bladder syndrome ( IC/PBS ) and to assess the safety and efficacy on IC/PBS symptoms . A total of 17 symptomatic IC/PBS patients were treated with intravesical LPs ( 80mg/40mL distilled water ) once a week for 4 weeks ( n=12 ) or twice a week treatment for 4 weeks ( n=5 ) . The primary outcome was the change in the O'Leary-Sant Symptom/Problem score and O'Leary-Sant total Score from baseline to Week 4 and Week 8 . Other outcome measurements included the changes in pain scale , urgency scale , voiding log , and patient global assessment . Both weekly and biweekly LP instillation regiments were well tolerated . The incidence of urinary incontinence , retention , or unanticipated adverse changes was not noted at any dose either during the treatment or at the 4-week follow-up . The O'Leary-Sant Symptom/Problem score , O'Leary-Sant total Score , and pain score were significantly improved from baseline at both dose regimens with added benefit with the biweekly regimen . Intravesical LPs treatment is safe and its efficacy has sustained duration . Furthermore large-scale , placebo-controlled studies are warranted to assess the efficacy for this promising new treatment for IC/PBS
