A new reusable Skin-protective sphygmomanometer cuff
Journal of Clinical Monitoring and Computing, 2010Co-Authors: Eri Gi, Shigekazu Sugino, Tada-aki Kawae, Hiroaki Watanabe, Akiyoshi NamikiAbstract:Objective Repeated blood pressure measurement with a sphygmomanometer often produces Skin Redness and subcutaneous bleeding in clinical settings. Recently, we have produced a new reusable Skin-protective cuff with an additional sheet. Methods We evaluated Skin damage and blood pressure measurement accuracy when using the new cuffs. We also evaluated upper arm deformity by CT scan during cuff inflation. Pulse wave amplitude evaluation was carried out with an NIBP simulator and our original system. Results The use of this cuff reduced subcutaneous bleeding and pain with cuff inflation and enabled accurate blood pressure mea- surement. Conclusion We produced a new Skin protec- tive reusable sphygmomanometer cuff.

Morphine gel 0.3% does not relieve pain during topical photodynamic therapy: a randomized, double-blind, placebo-controlled study.
Acta dermato-venereologica, 2006Co-Authors: Jette Skiveren, Merete Haedersdal, Peter A. Philipsen, S.r. Wiegell, Hans Christian WulfAbstract:There is a demand for pain relief during photodynamic therapy. We therefore investigated the efficacy and side-effects of topical morphine gel 0.3% for pain relief during topical photodynamic therapy in a randomized, double-blind, placebo-controlled study. The study involved 28 patients with actinic keratoses or basal cell carcinomas. Each patient was treated with photodynamic therapy after superficial curettage of 2 treatment areas that were randomized to morphine gel or placebo gel. The gels were applied 15 min before illumination. Pain was assessed pre-illumination, during, and immediately after illumination, using a numeric rating scale. Skin Redness was determined by reflectance spectrophotometry and the size of the treated area by protoporphyrin IX fluorescence. There were no differences between the areas according to accumulation of protoporphyrin IX (p =0.34), size of fluorescence areas (p =0.84), or Skin Redness (p =0.95). There was no significant pain relief of topical morphine gel compared with placebo gel (p >0.23). This negative result suggests that opioid receptors may not be involved in the pain induced by photodynamic therapy.

Side effects from the pulsed dye laser: the importance of Skin pigmentation and Skin Redness.
Acta dermato-venereologica, 1998Co-Authors: Merete Haedersdal, Jan Efsen, M. Gniadecka, Bech-thomsen N, Keiding J, Hans Christian WulfAbstract:The pulsed dye laser is the treatment of choice for port-wine stains. In this study we evaluate the importance of preoperative Skin pigmentation and Skin Redness for the development of side effects from one treatment with the pulsed dye laser. A risk assessment is performed and Skin reflectance measurement objectifies postoperative pigmentary changes. Fourteen human volunteers (Skin types I to V) were laser-treated on the inside of the proximal brachium. Photographic documentation was used for blinded, clinical evaluation of side effects 3 and 6 months postoperatively. Skin was artificially reddened using topical application of 10% nicotinic acid cream. The development of pigmentary alterations and texture changes depended on the preoperative pigmentation and Redness degrees. The risk of inducing clinically visible pigmentary alterations and texture changes increased with higher preoperative Skin pigmentation and Redness degrees, and with the application of increasing laser doses. Pigmentary alterations were induced at a lower fluence level than texture changes. The risk of side effects was higher 3 months postoperatively than 6 months postoperatively, substantiating a gradual disappearance of side effects. Skin reflectance measurements documented postoperative hyperpigmentation that faded partially from 3 to 6 months postoperatively. This is the first human experimental model for port-wine stains which provides quantitative data on the relationship between preoperative Skin colours and postoperative clinically disturbing side effects.

Changes in Skin Redness, Pigmentation, Echostructure, Thickness, and Surface Contour After 1 Pulsed Dye Laser Treatment of Port-wine Stains in Children
Archives of dermatology, 1998Co-Authors: Merete Haedersdal, Jan Efsen, M. Gniadecka, Hanne Fogh, Jens Keiding, Hans Christian WulfAbstract:Background: The pulsed dye laser is the treatment of choice for children with port-wine stains (PWSs). Evaluation of treatment outcome and adverse effects is traditionally based on subjective clinical scoring systems. We intend to objectify treatment results and adverse reactions after 1 treatment with the pulsed dye laser. Design: A before-and-after trial using Skin reflectance to detect changes in Skin Redness and pigmentation, ultrasonography to evaluate changes in echostructure and Skin thickness, and 3-dimensional surface contour analysis to detect changes in surface texture. Patients: Twelve children with PWSs. Setting: A university dermatological department. Results: The Skin reflectance‐determined change in Skin Redness correlated with the clinical response (r=0.46, P,.002). The percentage of reflectance-determined lightening was equal for pink, red, and dark red PWSs (median, 42.9%). Skin pigmentation increased after laser treatment (P,.007). Ultrasonography revealed lower dermal echogenicity of preoperative PWSs than of postoperative PWSs (P,.007) and healthy Skin (P,.001). An increase in echogenicity reflected a decrease in the dermal water (blood) content. Variations were found in the dermal localization of the PWS. Skin thickness was significantly higher in the PWS before treatment than after (P,.001). The preoperative lesional thickness correlated inversely with the ultrasound-assessed treatment response (r=0.35, P,.04). The surface contour parameters decreased significantly after laser treatment, indicating a flattening of the Skin surface. The contour changes correlated positively with treatment response. By clinical evaluation, no hypopigmentation or texture changes were detected. Conclusion: The evaluation of treatment outcome and adverse effects is refined by the use of Skin reflectance, ultrasonographic, and surface contour analysis.

Skin temperature and phototest evaluation
Photodermatology photoimmunology & photomedicine, 1996Co-Authors: M. Gniadecka, Jørgen Lock-andersen, F. Fine De Olivarius, Hans Christian WulfAbstract:The degree of erythema following UV irradiation is known to depend upon Skin temperature at the time of UV exposure. We investigated whether changes in Skin temperature at the time of erythema assessment influenced the level of erythema. Twenty-two healthy people (mean age 26 years) were irradiated with solar stimulated radiation on previously UV un-exposed buttock Skin. The erythematous reactions were evaluated 20-24 h after irradiation by visual scoring and by measurements of Skin reflectance and laser Doppler flowmetry. The readings were done at the baseline level at 21 degrees C room temperature where Skin temperature was 30.0 +/- 1.7 degrees C and subsequently after Skin warming to 37.2 +/- 2.5 degrees C and after cooling to 22.8 +/- 2.6 degrees C. After Skin warming, a clinically evaluated erythema grade [0, (+), +, ++, + + +] was scored higher for at least one reaction in 10 of 22 individuals (45%). In the same proportion of subjects, changes to lower erythema grades were detected upon cooling. Skin warming caused an increase in laser Doppler blood flux, but Skin cooling did not have a significant effect on cutaneous perfusion. Skin Redness measured by Skin reflectance was relatively stable during the cooling phase, but a significant increase in Skin Redness was noted for 0 reaction upon Skin warming. For ++ and + + + reactions a small but significance decrease in reflectance was noted. Our results indicate that alterations in Skin temperature, especially a temperature increase, modulates the degree of UV-induced erythema moderately. The temperature-dependent changes as an assessment of the (+) reaction are of practical significance, since this reaction is used for the assessment of cutaneous photosensitivity.
