The aim of the study was to investigate steady state levels, dynamics and reproducibility of cardiovascular variables and electrodermal activity in different skin areas in response to minor physiological and mental stimuli in healthy subjects in the thermoneutral zone, carried out in high time resolution. Methods: Thirteen healthy subjects underwent experiments on two separate days. Non-invasive electrodermal activity in five different skin areas was measured continuously using a skin conductance method, including resting supine and sitting positions, performing deep inspirations, a mental challenge and being exposed to a sudden loud sound. Blood pressure, heart rate, radial artery blood flow, and skin perfusion were measured simultaneously. Results: Electrodermal activity in the right and left palms was almost identical, with rapid and large increases within a few seconds in response to stimuli, whereas no such significant changes were seen in the face, back, and abdomen. Radial artery blood flow and palmar skin perfusion changed synchronously with electrodermal activity for each stimulus, and were correlated to changes in blood pressure and heart rate. The response patterns in each subject were very similar on the two experimental days. There was very low spontaneous electrodermal activity in the supine position, contrary to the resting sitting position. Conclusion: The electrodermal activity increased rapidly and synchronously in both palms within a few seconds as a response to minor physiological and mental stimuli, synchronous with fluctuations in radial artery blood flow, palmar skin perfusion, and cardiovascular variables. The responses are reproducible from day to day, making them a stable and constant stimuli to be used for studies in patients with hyperhidrosis.

“…To see whether a sweat secretion problem existed on the lesional area of the skin, palmar sweat volume was measured using a cutaneous evaporation meter (portable sweat meter TS-100; TECHNO SCIENCE, Tokyo, Japan) according to the ventilation capsule method (Tomioka et al, 2005;Ohshima et al, 2008), and was compared with nonlesional areas. Probe (1 cm 2 ) of the sweat meter was applied on the target skin area, and the 2-minute sweat volume was measured at both the lesional and nonlesional areas on the palms of the PPP patients.…”

Acrosyringium Is the Main Site of the Vesicle/Pustule Formation in Palmoplantar Pustulosis

Pustulosis palmaris et plantaris or palmoplantar pustulosis (PPP) is a refractory pustular eruption on the palms and soles with unknown etiology. Numerous eccrine sweat pores exist on the palms and soles, suggesting the involvement of eccrine sweating in the pathogenesis of PPP. To the best of our knowledge, however, no definite abnormality in sweating has been documented in PPP. Accordingly, we analyzed the eccrine sweat duct involvement in the mechanism of vesicle formation in PPP. Dermatoscopy showed that PPP vesicles are located on the top of the ridges but not in the furrows. The sweat secretion in the lesional area was much lower than that in the nonlesional area, with or without pain stimulation to induce sweating. Immunostaining of horizontal sections of the lesions using antibodies against gross cystic disease fluid protein-15 (GCDFP-15) and epithelial membrane antigen (EMA) showed that these markers were localized in the cells lining the intraepidermal vesicles. Although the sweat antimicrobial peptides, dermcidin and human cathelicidin antimicrobial peptide 18 (hCAP-18)/LL-37, were detected in the fluid of the vesicles/pustules, neither dermcidin nor hCAP-18/LL-37 were overexpressed by neighboring keratinocytes. These findings suggest that the acrosyringium may be involved as the main site of the vesicle formation in the pathomechanism of PPP.

“…It is known that the hand grip exercise induces sweating of the contralateral hand. That reaction is used to determine therapeutic effects on hyperhidrosis, and the measurement method is the ventilated capsule method 27,28 . In the measurement by OCT, it has been reported that the mean volume of acrosyringia of healthy subjects was increased by the handgrip exercise 23,24 .…”

Optical coherence tomography (OCT) is a high‐resolution tomographic imaging technique that uses optical interference. OCT has enabled the non‐invasive three‐dimensional analysis of individual acrosyringia in the stratum corneum in human skin. However, no report on the measurement of sweating by OCT using clinical data from humans has been published to date. Twenty patients with hyperhidrosis and twenty healthy subjects were included in this study. Imaging of acrosyringia in the stratum corneum using OCT and measurement of the sweat rate using the ventilated capsule method were performed simultaneously. The hand grip exercise of the right hand was used as a load to induce sweating, and the left fingertip was measured before and after the exercise load. Five acrosyringia were extracted from each OCT image, and their volumes were calculated. The mean volume of each acrosyringium was divided by the thickness of the stratum corneum to calculate the mean cross‐sectional area of the acrosyringium. Furthermore, the number of sweat droplets on the skin surface was measured. The mean cross‐sectional area of acrosyringia after the load increased both in patients with hyperhidrosis and in healthy subjects (P < 0.001). The mean cross‐sectional area of acrosyringia of patients with hyperhidrosis was larger than that of healthy subjects (P < 0.001). The mean cross‐sectional area of acrosyringia and the sweat rate showed a positive correlation before and after the load (r = 0.88 to 0.91). The number of droplets also increased after the load (P < 0.001), and the number of droplets in patients with hyperhidrosis was higher than in healthy subjects (P < 0.001). Our study has shown that acrosyringia in the stratum corneum increase in proportion to the sweat rate. OCT is a rigorous and valuable method that can measure and quantify sweating in the body without being an invasive procedure.
