Opis
Inclusion Criteria:
- Men or women ≥ 18 years old.
- Patients suffering from chronic pelvi-perineal neuralgia (>3 months) with a DN4 score ≥4 at the inclusion visit, with or without symptoms of central sensitization, and with an indication for topical treatment with high-concentration capsaicin patch (PCHC).
- Patients who have signed the informed consent form for the study at the inclusion visit.
- Women must meet one of the following criteria at the time of inclusion:
- Use adequate contraceptive measures;
- or Be postmenopausal (aged over 50 years with amenorrhea for at least 12 months after discontinuation of all exogenous hormonal treatments);
- or (If aged under 50 years) have been amenorrheic for at least 12 months after discontinuation of exogenous hormonal treatments, with luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels consistent with postmenopausal levels;
- or Have undergone irreversible surgical sterilization (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), with documentation of the procedure.
Exclusion Criteria:
- Patients under guardianship, curatorship, or legal protection.
- Pregnant or breastfeeding women.
- Patients with contraindications to the use of the high-concentration capsaicin patch (PCHC): application on damaged skin, hypersensitivity to any of its components.

Eksperymentalny: Pain sensitization parameter testing
Pre-inclusion visit (routine care consultation): Verification of inclusion and exclusion criteria. Inclusion visit (Day 0): Consent signing, questionnaires (ConvergencePP Score/Central Sensitization Inventory, DN4), and a series of tests, followed by the application of the high-concentration capsaicin patch (PCHC) (performed during routine care). Day 30 visit (±7 days): Questionnaires (same as V1 + PGI-c) and a series of tests. |

Composite criterion
Ramy czasowe: Difference between Day 0 and Day 30
|
Composite criterion constructed from a Principal Component Analysis including the differences between Day 0 (before patch application) and Day 30 in pain perception thresholds (to cold, heat, pressure, and mechanical stimulation) in both the area treated with the high-concentration capsaicin patch and the corresponding dermatome, as well as the change in the pain receptive field area in the treated zone and the area under the curve of temporal summation measurements.

Measure the correlation between Convergences PP scores, CSI, and semi-objective sensitization data
Ramy czasowe: Between before and 1 month after patch application
|
Measure the correlation between Convergences PP scores, CSI, and semi-objective sensitization data. The Convergences PP score is a clinical questionnaire used to diagnose sensitization in the pelvic region. A score is considered positive from 5/10 (sensitivity = 95%, specificity = 87%). The Central Sensitization Inventory (CSI) is a self-administered questionnaire used to diagnose central sensitization. A score is considered positive from 40/100. Correlations between the Convergences PP score, CSI, and semi-objective sensitization data (pain thresholds and temporal summation) will be measured using Spearman's correlation coefficient to explore the relationships between these variables. |
