116 Blood Flow of Dorsal Clitoral Artery Assessed With Color Doppler Ultrasound in Women with Vulvodynia Compared to Healthy Controls
Bibliographic record
Abstract
Vulvodynia, a chronic vulvar pain condition, affects women of all ages and is the main cause of dyspareunia in pre-menopausal women. Alteration of local blood perfusion was suggested to be involved in several genital conditions such as genitourinary syndrome and lichen sclerosus. However, the scientific literature investigating local artery flow in women with vulvodynia remains limited. A decreased genital blood perfusion was shown in women with vulvodynia during sexual response compared to healthy controls. In contrast, vasodilation was suggested as a mechanism involved in the pathophysiology of vulvodynia in a study using laser doppler imaging. Therefore, inconsistency regarding local artery flow of women with vulvodynia requires further research. To evaluate and compare blood flow of the dorsal clitoral artery in women diagnosed with vulvodynia and healthy controls using color doppler ultrasound. This cross-sectional study evaluated the blood flow of the clitoral artery in 20 women diagnosed with vulvodynia according to Friedrich‘s criteria and 21 healthy controls. The assessments of dorsal clitoral artery was performed by a trained evaluator using color doppler ultrasound. Participants were asked to abstain from sexual activities 24 hours prior the exam. The evaluation was performed in the morning during follicular phase (from 1st to 3rd days of menstrual cycle) in a room with temperature set at 22 ºC. After a 10-min rest period in a supine lying position, an assessor blinded to diagnosis performed the assessment of the blood flow of the dorsal clitoral artery using the color doppler ultrasound (Voluson, 730 Expert; linear transducer 3-8x MHz). The extraction of the peak systolic velocity (PSV), time-averaged maximum velocity (TAMX), end-diastolic velocity (EDV), pulsatility index (PI) and resistance index (RI) was performed at rest considering the mean value of three consecutive waveforms. Mann-Whitney tests were used to compare doppler parameters between the two groups.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
