Abstract
Androgenetic alopecia is a common type of hair loss, which is generally influenced by genetic factors and systemic androgens resulting in follicular miniaturization.1 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.1 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
BACKGROUND Masseter hypertrophy is the main cause of an asymmetrical and squared lower facial contour in the Asian community. Botulinum toxin injection technique is crucial to treat this condition. OBJECTIVE To improve injection techniques for masseter hypertrophy by elucidating the distribution of the injections within the masseter. METHODS Thirty masseter muscles were divided into 6 groups of 5 muscles each. Each group received one 0.2- or 0.3-mL injection at Point A, B, or C according to a three-point technique. Muscle dimensions and dye of the primary and secondary dye spreading were measured. RESULTS The average muscle length, width, and thickness were 69.87, 33.50, and 11.23 mm, respectively. The average primary longitudinal and horizontal spreading was 36.56 and 15.60 mm, respectively. No statistically significant difference was found between 0.2- and 0.3-mL injections at each point. CONCLUSION The three-point technique best fits in the safe zone and should be the standard injection technique for masseter hypertrophy. Injection at Points B and C may create secondary spreading that affect the risorius muscle and the parotid gland which are the cause of asymmetrical smiling and xerostomia, respectively. The dosage should be adjusted according to the muscle volume and not only the thickness.

Abstract
Purpose To study the effectiveness and safety of upper and lower eyelid treatment with combined application of three modes of 2940-nm erbium-doped yttrium aluminium garnet (Er:YAG) and 1064-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) lasers in patients with baggy eyelids (formed by intraorbital fat herniation) who exhibited meibomian gland dysfunction (MGD). Patients and Methods In this prospective cohort study, patients with baggy eyelid who exhibited MGD received combined laser treatment at baseline, as well as at the 4-, 8-, and 12-week follow-ups. The primary endpoint was meibum quality score at 16- and 24-week follow-ups; secondary endpoints were ocular surface index scores, tear film lipid layer thicknesses, tear break up times (TBUTs), Oxford scheme grades, and meibography grades at 16- and 24-week follow-ups. Adverse events, uncorrected visual acuities, best-corrected visual acuities, and intraocular pressures were also recorded. Results Sixteen patients (four men and 12 women; mean age, 56.38 ± 8.64 years) were included. Meibum quality scores at the 16-week follow-up were significantly lower than scores at baseline (p=0.043) and at the 24-week follow-up (p=0.015). TBUT was significantly exacerbated at the 24-week follow-up, compared with baseline (p=0.001) and the 16-week follow-up (p=0.006). There were no significant changes in other parameters. All adverse events were mild and resolved without additional treatment. Conclusion Combined application of three modes of 2940-nm Er:YAG and 1064-nm Nd:YAG lasers on upper and lower eyelids significantly improved meibum quality in patients with MGD; it ameliorated symptoms and signs of dry eye disease at 4 weeks after completion of laser treatment.

Abstract
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
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
Frontal fibrosing alopecia (FFA) is a distinctive lymphocytic scarring alopecia with rapid increase in prevalence. Most FFA series are retrospectively reported from Caucasians with only few from Asians. The objective of this study was to characterize the clinical, trichoscopic and histopathological findings as well as treatment outcomes. This was a retro-prospective cohort study of patients diagnosed with FFA from 1 January 2010 to 1 November 2019. All patients were asked to present for re-examination. Clinical, trichoscopic, histopathological and laboratory data were recorded. A questionnaire was used to investigate hair care, hairstyle and facial skin care compared with age-matched normal controls. Multivariate analysis was performed in order to clarify factors associated with severity. All 58 FFA patients were female, of whom 27.6% were premenopausal, 37.7% had a history of surgical menopause, 13.8% had thyroid diseases, 69% had eyebrow loss and 32.8% facial papules. On physical examination, 10.3% showed linear pattern, 46.6% diffuse pattern and 43.1% pseudo-fringe sign. Concomitant lichen planopilaris was found in 25.9%, lichen planus pigmentosus in 24.1% and female pattern hair loss in 48.3%. The most common trichoscopic characteristics in the frontal hairline were lack of follicular ostia (91.4%), perifollicular scales (79.3%) and perifollicular erythema (63.8%). Up to 90% of patients reported FFA as improved or stable after receiving antiandrogen (finasteride or dutasteride) or antimalarial with topical treatment. Multivariate analyses revealed that facial lentiginous macules and trichoscopic perifollicular erythema at the frontal area were FFA severity-associated factors. "Front puff" Thai hairstyle was associated with FFA, while sunscreens and other cosmetic products were not. In conclusion, diffuse and pseudo-fringe sign pattern are common in Asian FFA. The most common autoimmune systemic comorbidity is thyroid disease, while common concomitant dermatological diseases are female pattern hair loss, lichen planopilaris and lichen planus pigmentosus. Antiandrogens or antimalarial plus topical treatment are the most useful therapy.

Abstract
Delivering cells to desired locations in the body is needed for disease treatments, tissue repairs, and various scientific investigations such as animal models for drug development. Here, we report the solid composite material that when embedded with viable cells, can temporarily keep cells alive. Using the material, we also show the fabrication of detachable dissolvable microneedles (DMNs) that can instantly deliver viable cells into skin tissue. B16-F10-murine-melanoma (B16-F10) and human-embryonic-kidney-293T (HEK293T) cells embedded in the solid matrix of the hyaluronic/polyvinylpyrolidone/maltose (HA/PVP/maltose) mixture show 50.6 ± 12.0 and 71.0 ± 5.96% survivals, respectively, when kept at 4 °C for 24 h. Detachable DMNs made of the HA/PVP/maltose mixture and loaded with B16-F10-cells were constructed, and the obtained DMN patches could detach the cell-loaded needles into the skin within 1 min of patch application. In vivo intradermal tumorgrafting mice with the DMNs containing 800 cells of B16-F10 developed tumors 10 times bigger in volume than tumors induced by hypodermic needle injection of suspension containing 100,000 cells. We anticipate this work to be a starting point for viable cell encapsulation in the solid matrix and viable cell delivery via DMNs.

Abstract
Background: Centella asiatica, a medicinal plant, has been used traditionally to promote wound healing. Its efficacy on promoting postlaser resurfacing wound healing is lacking. Methods: Thirty individuals with facial acne scars underwent a treatment with 2940 nm Er:YAG laser. Half side of the face was randomized to receive 0.05% w/w ECa 233 gel, a standardized extract of C. asiatica, and the other half a placebo gel. The gels were applied four times daily for 7 days then twice daily for 3 months. Erythema, melanin, and texture index (TI) from Antera3D,® and skin biophysics were obtained at baseline, days 2, 4, and 7, then every 2 weeks for the first month, and every month for 3 months. Three blinded dermatologists assessed the photographs and provided a grading scale of wound appearances. Results: The ECa 233 treated side exhibited significantly less erythema index over total follow-up by 0.03 U (coefficient = -0.03 [95% CI -0.06 to -0.0006]; p = 0.046). In keeping with the physicians' assessment that showed significantly higher improvements in skin erythema at days 2, 4, and 7 (p = 0.009, 0.0061, 0.012), crusting at days 2 (p = 0.02), and general wound appearance at days 2, 4, and 7 (p = 0.008, 0.001, 0.044), TI showed a trend toward better outcome in the ECa 233 group. Skin biophysics did not differ between the two groups. Conclusion: ECa 233 might be an option for postlaser treatment to improve wound appearance.

Abstract
OBJECTIVES To investigate the efficacy of pulsed-dye laser (PDL) as an adjunctive treatment for facial papulopustular eruptions from EGFR inhibitors (EGFRi). METHODS Fourteen patients with facial acneiform eruptions were recruited. Half side of the face was randomized to receive PDL treatment while the other side served as a control. The treatments were delivered every 2 weeks for 4 sessions. The patients were seen at baseline, weeks 2, 4, 6, 8, and 10. Erythema index (EI) measured by colorimeter, the papulopustular lesion count and physician global assessment (PGA) were obtained. Patients were allowed to use their standard treatments for their eruptions. RESULTS Both arms had a significant decrease in EI from baseline at each subsequent visit. In the laser treated side, the mean (95%CI) EI decreased from 23.5 (22.24-24.76) at baseline to 16.3 (15.01-17.59) at week 10, while those of the sham were 23.49 (22.23-24.75) to 20.51 (19.22-21.8), respectively. The mean change was significantly lower in the PDL arm from week 4 onwards. The lesion counts in both groups also decreased significantly, but the mean difference between the arms was not different. PGA scores followed the same pattern as EI. CONCLUSIONS Adjunctive treatment with PDL was a safe and effective treatment. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Abstract
BACKGROUND Currently, low-level laser therapy (LLLT) has been approved as a new treatment for androgenetic alopecia (AGA). However, it has not been elucidated how LLLT promotes hair growth in vivo. OBJECTIVES To investigate the change in protein expression from dermal papilla (DP) tissues in male AGA patients after LLLT treatment using liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis. METHODS This is an open-label, prospective, single-arm study obtained punch scalp biopsy specimens from patients with AGA before and after LLLT treatment. Each subject was self-treated with helmet type of LLLT (655 nm, 5 mW) device at home for 25 minutes per treatment every other day for 24 weeks. LC-MS/MS analysis based on the dimethyl labeling strategy for protein quantification was used to identify proteins expressed in DP tissues from AGA patients. RESULTS Proteomic analysis revealed 11 statistically significant up-regulated and 2 down-regulated proteins in LLLT treated DP compared with baseline (P < 0.05). A bioinformatic analysis signifies that these proteins are involved in several biological processes such as regulation of cellular transcription, protein biosynthesis, cell energy, lipid homeostasis, extracellular matrix (ECM), ECM structural constituent, cell-cell/cell-matrix adhesion as well as angiogenesis. ATP-binding cassette sub-family G member, a transporter involved in cellular lipid homeostasis, was the most up-regulated protein. Additionally, LLLT increased the main ECM proteins in DP which results in a bigger volume of DP and a clinical improvement of hair diameter in AGA patients. CONCLUSION We identified the proteome set of DP proteins of male patients with AGA treated with LLLT which implicates the role of LLLT in promoting hair growth and reversing of miniaturization process of AGA by enhancing DP cell function. Our results strongly support the benefit of LLLT in the treatment of AGA. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Abstract
The utility of the ear crease sign, anterior tragal crease (ATC), as a marker of atherosclerosis is yet to be established. The intima-media thickness of the common carotid artery (IMT-CCA) has been used as a noninvasive surrogate marker for atherosclerosis. History of traditional risk factors for atherosclerosis was obtained from 147 volunteers; ear examination was also performed and venous blood was drawn for laboratory analysis. The volunteers then underwent an ultrasonography measurement of the IMT-CCA. In univariate analysis, presence of ATC, age, underlying hypertension, diabetes mellitus, ischemic heart disease, cerebrovascular disease, cigarette smoking, low-density lipoprotein, and high-sensitivity C-reactive protein were significantly associated with the IMT-CCA. Further multivariate analysis confirmed a significant association between the presence of ATC and IMT-CCA, when adjusted for other factors (adjusted βATC = .010, 95% confidence interval: 0.0021-0.019). Anterior tragal crease is a potential clinical sign that can predict atherosclerosis. The sign is easily recognizable and may help health-care professionals to identify those at risk of atherosclerosis, especially in people with no clinical signs of the disease.

Abstract
Introduction: Despite its clinical features of multiple, confluent, small, whitish, smooth, and clear-demarcate papules on the neck and back, the pathogenesis of white fibrous papulosis of the neck (WFPN) is still unknown. The lesions increase progressively and do not regress over time. However, no effective treatment has yet been identified. Case Report: We reported the successful results of a female patient receiving efficacious treatment for her extensive lesions of WFPN with nonablative fractional photothermolysis laser (Fractionated 1550-Erbium Glass laser). Conclusion: This photothermolysis laser could then be suggestive as the therapeutic option for WFPN.

Abstract
Of all the cytokines or growth factors that have been postulated to play a role in hair follicle, insulin-like growth factor-1 (IGF-1) is known to be regulated by androgens. However, how IGF-1 is altered in the balding scalp has not yet been investigated. In this study, expressions of IGF-1 and its binding proteins by dermal papilla (DP) cells obtained from balding versus non-balding hair follicles were quantified using growth factor array. DP cells from balding scalp follicles were found to secrete significantly less IGF-1, IGFBP-2 and IGFBP-4 (P < 0.05) than their non-balding counterparts. Our data confirmed that the downregulation of IGF-1 may be one of the important mechanisms contributing to male pattern baldness.

Abstract
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
BACKGROUND Several growth factors and cytokines have been shown to be involved in normal hair cycling as well as in androgenetic alopecia (AGA). However, the molecular cascades in AGA downstream from androgen receptor activation are far from being fully elucidated. OBJECTIVES We sought to determine the difference in the protein expression of growth factors/cytokines in balding vs. nonbalding scalp specimens from the same individuals affected with AGA. METHODS Balding and nonbalding scalp specimens were collected from four men with pattern baldness. Dermal papilla (DP) cells were isolated and cultured. Quantifying the protein expression of growth factors and cytokines expressed by these cells was performed using Quantibody® Human Growth Factor Array-1 (RayBiotech, Inc., Norcross, GA, U.S.A.). RESULTS Brain-derived nerve factor (BDNF) protein expression was upregulated by approximately 12-fold in supernatants obtained from balding as compared with nonbalding DP cells (P < 0·001). Expression of neurotrophin-3 and of β-nerve growth factor was also upregulated. On the other hand, protein expression of insulin-like growth factor-1 and its binding proteins as well as of the vascular endothelial growth factor family were significantly downregulated in the balding scalp. CONCLUSIONS Neurotrophic factors, especially BDNF, may be important in mediating the effects of androgens on hair follicles, serving as a negative regulatory control signal. Further studies may lead to novel pharmacological interventions in AGA.
