An investigation about chronic prostatitis in ankylosing spondylitis.

Background: Chronic prostatitis has been a common disease reported with high frequency in ankylosing spondylitis (AS) even from decades ago. Infectious (Chlamydia trachomatis) or non-infectious (uric acid) prostatitis can hypothetically trigger vertebral inflammation in AS. This study aimed to assess the features of chronic prostatitis in patients with AS compared to healthy controls.

Cultural adaptation of the National Institutes of Health--chronic prostatitis symptom index (NIH-CPSI)--to Brazilian spoken Portuguese: NIH-CPSI (Braz).

Objectives: To create a Brazilian version of the National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) using a cross-cultural adaptation process.

Materials And Methods: The nine items of the NIH-CPSI were translated to Portuguese, by two independent translators, of native Portuguese language origin, and it was obtained a single version, that was retranslated to English by two English native spoken translators, in order to correct any discrepancies. Those versions were compared to the original text, the modifications were applied and it was created a final version in Portuguese.
