The effect of nitrogen plasma on the skin and hair follicles: a possible promising future for the treatment of alopecia

AbstractNowadays, there is a great attention to the plasma applications in medicine. Not only does cold atmospheric pressure plasma provide a therapeutic opportunity to control redox-based processes, it is also an innovative method in rejuvenation. Given the current interest in new methods of rejuvenation, we aimed to introduce a novel pulsed nitrogen plasma torch with potential use in rejuvenation. We investigated production of reactive species at different  pulse energy by spectroscopy and also measured nitric oxide and O2 concentration and evaluated the flame temperature. Fifteen Wistar rats were divided into three groups based on the applied energy settings; the skin of the animals was processed with plasma. For quantitative evaluation of dermis, epidermis and hair  follicles (to confirm the effects of this technique on rejuvenation), skin biopsies were taken from both unexposed and treated areas. The spectroscopy results showed the presence of nitric oxide in plasma and the concentration was suitable for dermatological applications. A significant increase wa s observed in epidermal thickness, fibroblast cell proliferation and collagenesis (P

CONCLUSIONS: Cutaneous vasculopathy related to the skin, such as livedo reticularis and ulcers of torpid evolution due to cutaneous vasculopathy are extremely rare. Thus, it is necessary to include skin ulcers as one of the phenotypic manifestations of NF-1. PMID: 31730516 [PubMed - in process]

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

Alopecia is a skin condition of great social and psychologic impact. Primary alopecia originates from the hair follicles and usually does not have systemic manifestations; however, secondary alopecia can affect the hair follicles in the setting of systemic diseases, medications, and external trauma. Connective tissue diseases, granulomatous diseases, bullous diseases, infections, and tumors are some of the systemic diseases that will be covered in this review. Trichoscopy is a useful noninvasive tool that can help with the diagnosis in the office and can guide the selection of the optimal site for the scalp biopsy.

Conclusions There was a significant relation between the severity of alopecia and treatment outcome. (p=0.038) Patients with alopecia areata had significantly better response when compared to alopecia totalis and universalis. There was no statistically significant relation with other parameters such as disease duration, age, gender, atopy history, age of onset, and histopathological features.

Authors: Starace M, Alessandrini A, Baraldi C, Piraccini BM Abstract Erosive pustular dermatosis of the scalp is a rare chronic inflammatory disorder defined. It usually affects elderly people and is characterized by extensive pustular lesions, erosions, and crusts located on the scalp. The pathogenesis of this disease is not completely understood, but a known predisposing factor is skin trauma. Autoimmune disorders including rheumatoid arthritis, autoimmune hepatitis, Hashimoto thyroiditis, and Takayasu aortitis are associated diseases reported. The clinical examination reveals erythema, erosions, crusts, follicul...

In conclusion, our patient and potentially other patients that carry a similar ODC1 gain-of-function mutation might benefit from treatment with DFMO, a drug with a good safety profile, to suppress the exceptionally high ODC activity and putrescine levels in the body.
