Acupuncture,electrostimulation, and reflex therapy in dermatology

Acupuncture is an old therapeutic method that includes both needle and nonneedle acupuncture. Nonneedle acupuncture includes moxibustion, cupping, and acupressure. In the field of dermatology, acupuncture has been reported to be beneficial for the treatment of acne, postherpetic neuralgia, psoriasis, atopic dermatitis, and urticaria. In acupuncture treatment of dermal diseases, both the filiform needle and the cutaneous needle are powerful tools. In the treatment of refractory dermal diseases, cutaneous needle acupuncture is usually followed by cupping to intensify the therapeutic effect. In cases where needle acupuncture is not possible, acupuncture-like transcutaneous electrical nerve stimulation (TENS) is a good alternative. In addition, reflex therapy based on foot reflex areas may also be an alternative. A lack of controlled studies is the main drawback for the methods mentioned above. However, the experiences from experts in this field may offer us new ideas to resolve refractory disorders in dermatology.     

Acne treatment with a 1,450 nm wavelength laser and cryogen spray cooling

BACKGROUND AND OBJECTIVES: A laser with a wavelength in the mid-IR range targeting the depth in skin where sebaceous glands are located in combination with cryogen spray cooling was evaluated for treatment of acne. In this non-ablative treatment, the laser energy heats the dermal volume encompassing sebaceous glands whereas the cold cryogen spray preserves the epidermis from thermal damage. STUDY DESIGN/MATERIALS AND METHODS: Monte Carlo simulations and heat transfer calculations were performed to optimize the heating and cooling parameters. A variety of heating and cooling parameters were tested in an in vivo rabbit ear study to evaluate the histological effect of the device on sebaceous glands and skin. Similar experiments were performed on ex vivo human skin. A clinical study for the treatment of acne on backs of human males was also conducted. RESULTS: Monte Carlo simulations and heat transfer calculations resulted in a thermal damage profile that showed epidermal preservation and peak damage in the upper dermis where sebaceous glands are located. Ex vivo human skin histology confirmed the damage profile qualitatively. In vivo rabbit ear histology studies indicated short-term thermal alteration of sebaceous glands with epidermal preservation. In the human clinical study on the back, a statistically significant reduction in lesion count on the treated side compared to the control side was seen (p < 0.001). Side effects were transient and few. CONCLUSIONS: The studies reported here demonstrate the feasibility of treating acne using a photothermal approach with a mid-IR laser and cryogen cooling.     

Topical 5-aminolaevulinic acid photodynamic therapy for the treatment of skin conditions other than non-melanoma skin cancer

Topical 5-aminolaevulinic acid (ALA) photodynamic therapy (PDT) is used increasingly for superficial non-melanoma skin cancer (NMSC) and dysplasia. However, the relative accumulation of the photosensitizer protoporphyrin IX (PpIX) in diseased tissue is not specific for neoplastic disease, and has been shown after the application of ALA to benign proliferative skin conditions such as viral warts and psoriasis. This review appraises the quality of evidence available for the use of topical ALA-PDT in the treatment of skin conditions other than NMSC. The diseases that have been studied in most detail are recalcitrant viral warts, acne, psoriasis and cutaneous T-cell lymphoma. Publications relating to the treatment of other diseases by topical PDT are restricted to small case series or case reports. The relevant literature will be discussed and the potential for topical PDT in the treatment of several skin diseases is highlighted, although more detailed studies are required to clarify the role of PDT beyond the treatment of NMSC.
