Inclusion Criteria:
- Only healthy controls: Subject is in good health, based on medical history and
physical examination
- White (Caucasian) male or female subjects, aged > or = 8 year.
- Subject is capable and willing to give informed consent.
Exclusion Criteria:
- Any abnormality of the skin which may interfere with the study assessments.
- Excessive hair growth on the volar surface of the forearm.
- Excessive tanning (any exposure to sunlight or a tanning bed which would cause a
sunburn reaction) throughout the study and incapable to cover the forearms for 24
hours prior to the study period.
- Subject using topical treatments on the forearm.
- History of sensitivity to the fruits of capsicum plants (e.g. chilli peppers).
- Any situation that can compromise the study, including a predictable lack of
cooperation from the volunteer.

Device: Temperature sensitivity measurement with Advanced Thermal Stimulation
|
Other: Challenge agent: placebo
|
Other: Challenge agent: capsaicin
|
Device: Mechanical stimulation with Von Frey filaments
|
Primary Outcome(s)
|
Change from baseline of the dermal blood flow response to topical applied capsaicin at 10, 20, 30, 40, 50 and 60 minutes, measured with Laser Doppler Imaging and expressed in % change to baseline
[Time Frame: Day 1 at baseline and 10, 20, 30, 40, 50 and 60 minutes after capsaicin application]
|
Secondary Outcome(s)
|
Change from baseline of the skin sensitivity response after topical applied capsaicin at 10, 20, 30, 40, 50 and 60 minutes, measured with the Numerical rating scale and skin sensitivity to mechanical stimulation, measured with Von Frey filaments.
[Time Frame: Day 1 at baseline and 10, 20, 30, 40, 50 and 60 minutes after capsaicin application]
|
Temperature sensitivity (detection and pain threshold), measured with Advanced Thermal stimulation and expressed in degrees Celsius.
[Time Frame: Day 1]
