Androgenetic alopecia is a common type of hair loss, which is generally influenced by genetic factors and systemic androgens resulting in follicular miniaturization. It can cause cosmetic problems leading to psychological distress among affected men and women. Effective standard medical treatments available are topical minoxidil 2 to 5%, oral finasteride, oral dutasteride, and hair transplantation. However, some patients do not achieve favorable results with standard treatments. For these reasons, other novel treatments have been developed, including new medications, regenerative medicines (autologous platelet-rich plasma, adipose-derived stem cells, micrograft generation, and exosome), and low-level laser therapy [ABSTRACT FROM AUTHOR]

We evaluated the efficacy and safety of red light LED as an adjuvant treatment for epidermal growth factor receptor inhibitor-induced paronychia. Eight patients were recruited in this randomized, single-blinded controlled trial. They were randomized to receive red-light on one hand or foot 2–3 times/week for 6 weeks while the contralateral side served as controls. The standard treatments were continued. Erythema and lesion elevation observed by Anthera® 3D, severity and pain scores were obtained at weeks 0, 2, 4, 6, and 8. The red light group showed significantly lower erythema, severity, and pain scores at weeks 4, 6, and 8. The elevation was significantly lower in the red light group at every follow-up visit. No adverse events occurred. Red light therapy may be an option as adjunctive treatment for EGFRi-induced paronychia. [ABSTRACT FROM AUTHOR]

OBJECTIVE: We sought to evaluate the efficacy and safety profile of an herbal extract combination comprising biochanin A, acetyl tetrapeptide-3, and ginseng extracts, and compare this to 3% minoxidil solution for the treatment of andogenetic alopecia (AGA). METHODS: A 24-week, triple-blinded, randomized controlled study was conducted in male and female subjects (N=32) with mild to moderate AGA. All were randomized to receive twice-daily, 1mL applications of the herbal extract combination or 3% minoxidil solution. Clinical efficacy from photographic assessment and adverse reactions were evaluated. RESULTS: There were thirty-two subjects (16 male, mean age 41.3±13.8 years), with AGA onset and duration of 35.5±13.6 and 6.5±5.1 years, respectively. The herbal extract combination demonstrated a comparable efficacy to 3% minoxidil solution. Expert panel photographic assessment observed a response to both treatments in most patients at 24 weeks, with no statistically significant difference in an increase of terminal hair counts (8.3% [P=0.009] and 8.7% [P=0.002] at 24 weeks in the herbal extract combinations and the 3% minoxidil solution groups, respectively). No local adverse reactions from the herbal extract combination were observed, but one subject developed scalp eczema after using the 3% minoxidil solution. CONCLUSION: The non-significant difference in clinical efficacy and safety to 3% minoxidil solution suggests that the herbal extract combination evaluated here could potentially be an alternative treatment with for AGA. Further studies with larger groups and longer follow-up periods are recommended to verify our results. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy and safety of pulsed-dye laser (PDL) for discoid lupus erythematosus (DLE) in a double blinded, randomized, controlled fashion. Method: Forty-eight DLE lesions from nine patients were recruited. The lesions on one side of the body were randomized into the treatment group and the other side served as a control. Treatments with the PDL (595 nm) were delivered every four weeks for four consecutive months. The patients were evaluated at weeks 0, 4, 8, 12, 16 and 24. Erythema index (EI) and Texture index (TI) were obtained by Antera3D®. Modified Cutaneous Lupus Erythematosus Disease Area and Severity Index (mCLASI) and physician global assessment (PGA) scores were assessed in every visit. Lesional skin biopsies before and after the PDL treatment were taken from four patients. Results: The lesions treated with the PDL demonstrated significantly more decreases in EI, TI and improvement in PGA scores compared to the control. Though there was improvement of mCLASI in the laser group, the significance difference was not observed. Interestingly, real-time polymerase chain reaction showed a reduction in CXCL-9, 10, IFN-γ, IL-1β, TNF-α and TGF-β. Additionally, post-treatment DLE lesions demonstrated decreased CD3, CD4, CD8 and CXCR3-positive cells. Conclusions: Improvements of DLE can be achieved with PDL. [ABSTRACT FROM AUTHOR]

Background: Localized hypertrichosis following cast application has been recorded, yet no studies characterized these changes systematically. Objective: To evaluate changes of hair length, diameter and density on the legs in patients after cast application. Materials and methods: Patients with leg injuries and cast application of at least 4 weeks' duration were included in the study. Immediately after cast removal, hair sampling was taken from both legs; cast and control sides. Hair length and diameter were measured by Olympus microscope software. Patients were also analyzed for global changes by three blinded dermatologists. Results: Fourteen patients, seven of whom were male, were included in this study. On the cast side, both hair length and diameter were significantly greater than the control side ( p < 0.001). Subjective evaluations by three blinded dermatologists agreed well with objective measurements and also demonstrated an increase in overall density. Degrees of hair changes did not correlate with the distance from injury sites. Conclusion: Cast application of at least 4 weeks' duration significantly stimulates hair growth in a diffuse pattern. This could possibly lead to novel therapeutic approaches for different types of alopecias. [ABSTRACT FROM AUTHOR]

Background and Objective: Lichen amyloidosis is characterized by amyloid deposition in the papillary dermis, presenting clinically with intensely pruritic hyperkeratotic papules. Various treatment modalities have been used but the results are generally unsatisfactory. Several studies show that non-ablative fractional lasers can be used to treat depositional diseases due to their capability of inducing transepidermal elimination of the dermal content. To investigate the efficacy and safety of a non-ablative fractional 1,550 nm Yttrium/Erbium fiber laser for the treatment of lichen amyloidosis., Materials and Methods: Ten subjects with a clinical and histological diagnosis of lichen amyloidosis were treated with fractional non-ablative laser using a 7-cm tip, with the parameter of 30 mJ/cm2 and 1,000 microscopic treatment zones (MTZ)/cm2 for three sessions at 4-week intervals. Clinical improvement (in terms of global improvement score, brownish/hyperpigmentation, thickness, and number of papules) was evaluated using a quartile grading scale at baseline, and 4, 12, and 24 weeks after the last treatment. Itch score and subjective satisfaction rates were also assessed. Adverse events were recorded, and pain was scored using a visual analog scale (VAS). Histologic changes were observed using standard staining with hematoxylin and eosin, as well as special stains of alkaline congo red and crystal violet at baseline and 4 weeks after treatment., Results: At 4 and 24 weeks after treatment, the lichen amyloid lesions had statistically significantly improved in all aspects compared to baseline (P = 0.01 and P = 0.016, respectively; Wilcoxon signed-rank test). However, partial recurrence was reported in 2 out of 10 subjects. All subjects rated itching symptom significantly improved after only the first treatment (P < 0.05). Minimal side effects were recorded, including a burning sensation, transient erythema, and edema. Histological evaluation demonstrated decreased epidermal thickness, and degeneration and shrinkage of amyloid material deposition in the papillary dermis. There was no amyloid material deposition noted in two out of eight histopathology studies., Conclusions: The non-ablative fractional 1,550 nm Ytterbium/Erbium fiber laser is safe and effective for the treatment of lichen amyloidosis. However, larger controlled studies are required to further establish the efficacy of this treatment., (© 2015 Wiley Periodicals, Inc.)
