Introduction: Skin electroporation is a promising treatment for transdermal drug delivery, gene electrotransfer, skin rejuvenation, electrochemotherapy, and wound disinfection. Although a considerable amount of in vitro and in vivo studies exists, the translation to clinics is not as fast as one would hope. We hypothesize the reason lies in the inadequate dosimetry, i.e. electrode configurations, pulse parameters, and pulse generators used. We suggest adequate dosimetry can be determined by mathematical modeling which would allow comparison of protocols and facilitate translation into clinics.Areas covered: We introduce the mechanisms and applications of skin electroporation, present existing mathematical models and compare the influence of different model parameters. We review electrodes and pulse generators, prototypes, as well as commercially available models.Expert opinion: The reasons for slow translation of skin electroporation treatments into clinics lie in uncontrolled and inadequate dosimetry, poor reporting rendering comparisons between studies difficult, and significant differences in animal and human skin morphology often dismissed in reports. Mathematical models enable comparison of studies, however, when the parameters of the pulses and electrode configuration are not adequately reported, as is often the case, comparisons are difficult, if not impossible. For each skin electroporation treatment, systematic studies determining optimal parameters should be performed and treatment parameters standardized.

皮肤电穿孔的机械学观点-成功应用的模型和剂量学:专家评论。

简介:皮肤电穿孔是一种用于经皮给药,基因电转移,嫩肤,电化学疗法和伤口消毒的有前途的治疗方法。尽管存在大量的体外和体内研究,但翻译到临床并不如人们所希望的那样快。我们假设原因在于剂量不足,即电极配置,脉冲参数和使用的脉冲发生器。我们建议可以通过数学模型确定足够的剂量,从而可以比较方案并促进临床翻译。涵盖的领域:我们介绍了皮肤电穿孔的机理和应用,介绍了现有的数学模型并比较了不同模型参数的影响。我们回顾一下电极和脉冲发生器,原型,专家意见:皮肤电穿孔疗法向临床的缓慢翻译的原因在于,剂量控制不受控制且不充分,报告不佳使研究之间难以进行比较,并且动物和人皮肤形态的显着差异通常在报告中被忽略。数学模型可以进行研究比较,但是,当没有充分报告脉冲的参数和电极配置时(通常是这样),比较比较困难,即使不是不可能。对于每种皮肤电穿孔治疗,应进行确定最佳参数的系统研究,并对治疗参数进行标准化。皮肤电穿孔疗法缓慢转入临床的原因在于:剂量控制不当和不足;报告不佳,使得研究之间难以进行比较;动物和人皮肤形态的显着差异通常在报告中被忽略。数学模型可以进行研究比较,但是,当没有充分报告脉冲的参数和电极配置时(通常是这样),比较比较困难,即使不是不可能。对于每种皮肤电穿孔治疗,应进行确定最佳参数的系统研究,并对治疗参数进行标准化。皮肤电穿孔疗法缓慢转入临床的原因在于:剂量控制不当和不足;报告不佳,使得研究之间难以进行比较;动物和人皮肤形态的显着差异通常在报告中被忽略。数学模型可以进行研究比较,但是,当没有充分报告脉冲的参数和电极配置时(通常是这样),比较比较困难,即使不是不可能。对于每种皮肤电穿孔治疗,应进行确定最佳参数的系统研究,并对治疗参数进行标准化。数学模型可以进行研究比较,但是,当没有充分报告脉冲的参数和电极配置时(通常是这样),即使不是不可能,也很难进行比较。对于每种皮肤电穿孔治疗,应进行确定最佳参数的系统研究,并对治疗参数进行标准化。数学模型可以进行研究比较,但是,当没有充分报告脉冲的参数和电极配置时(通常是这样),比较比较困难,即使不是不可能。对于每种皮肤电穿孔治疗,应进行确定最佳参数的系统研究,并对治疗参数进行标准化。
