Background and Aims
Defensins are peptides capable of reactivating latent LGR6 stem cells in the basal layer. When applied topically, these peptides can reduce signs of skin aging and increase dermal thickness. This study investigates the effects of a topical defensin formulation on extremity skin composition.Methods
An open label, single arm clinical trial was conducted on participants with dry, photoaged, or dull skin. A defensin-containing hand and body cream was applied twice daily for 6 weeks to the hands, forearms, elbows, and knees. Photographs and objective measurements of skin hydration, viscoelasticity (VE), retraction time (RT), thickness, density/transepidermal water loss (TEWL), as well as self-evaluation of skin quality and characteristics were obtained pre- and post- intervention.Results
After the study period, RT decreased by 56% across all body sites (p < 0.001) and VE improved at the elbow (125%, p = 0.009) and knee (110%, p < 0.001). Skin density also increased in all 4 body sites (40%, p < 0.001), while skin thickness increased at the elbow (29%, p = 0.03) and knee (17%, p = 0.04). Skin hydration increased at the elbow, knee, and forearm by 99%, 28%, and 16%, respectively (p < 0.05), while TEWL improved at the elbow only (−39%, p = 0.02). Patients' self-evaluations showed improvements in overall skin quality and in the domains of dryness, ashiness, wrinkling, pigmentation, redness, roughness, and discomfort (p < 0.05).Conclusions
Following 6-week use of a defensin-containing cream, subjects reported significant improvement across many subjective skin domains. Similarly, objective measurements demonstrated significant improvement in skin architecture at select sites. 相似文献2.

Background
Alopecia areata (AA) is characterized by limited non-scarring patchy alopecia, which appears as round or oval patches and is prone to recurrence, causing severe psychological burdens to patients. No specific device has been approved by the FDA for the treatment of baldness, but new treatments are being investigated and treatments such as the excimer laser, He- Ne laser, and excimer lamp have been proposed. A growing number of studies have found that fractional lasers also have great potential in the treatment of AA.Methods
A literature search and meta-analysis using Review Manager 5.4 software to investigate the efficacy of fractional laser treatment for AA.Results
Fractional laser combined with minoxidil (RR 1.32, 95% CI 1.17–1.49, p < 0.00001) or cortisol (RR 1.39, 95% CI 1.15–1.67, p = 0.00006) was more effective than either drug alone in the treatment of AA. Of course, the fractional laser alone was also effective in the treatment of AA (RR 10.33, 95% CI 2.07–51.36, p = 0.004) and more effective than cortisol alone (RR 1.86, 95% CI 1.36–2.52, p < 0.00001), and there was no effect on the occurrence of adverse effects (p = 0.49 > 0.05). When compared to other physical treatments of a comparable kind, fractional laser therapy's effectiveness was not significantly different (p = 0.15 > 0.05).Conclusion
Our results show that the use of fractional lasers can effectively treat alopecia areata. 相似文献3.

Background
The risk of recurrence after successful repigmentation in vitiligo has attracted attention from both patients and clinicians.Objectives
The recurrence rate and risk factors in cured patients with vitiligo were analyzed to improve clinical prevention and treatment.Methods
Clinical records of 76 patients with vitiligo who demonstrated at least 80% repigmentation were analyzed retrospectively. Single-factor analysis of variance and binary logistic regression analysis was employed to screen the risk factors of vitiligo recurrence.Results
Among the 76 cured patients, 26 relapsed (total recurrence rate of 34.2%). Among these, 20 relapsed within one year (recurrence rate of 26.3%). Single-factor analysis of variance revealed significant differences (p < 0.05) with the age of onset (yr), distribution of onset, and oral traditional Chinese medicine (TCM) intake between the recurrence and nonrecurrence groups. Binary logistic regression analysis displayed that the age of onset (yr) (p = 0.015, OR = 1.051), distribution of onset (p = 0.046, OR = 0.194), and oral TCM (p = 0.018, OR = 4.360) are significant risk factors for vitiligo recurrence.Conclusion
A total relapse rate of 34.2% was observed in cured vitiligo patients. The age of onset (yr), distribution of onset, and oral TCM are risk factors for vitiligo recurrence. The necessary interventions should be considered on these factors for reducing the recurrence rate of vitiligo. 相似文献5.

Background
COVID-19 pandemic has caused mask-related skin problems on health-care professions, yet very few studies have investigated the prevalence in oriental general population.Objective
To investigate the prevalence of mask-related adverse skin reactions in Orientals, to explore psychological influence, to identify risk factors for mask-related acne exacerbation.Methods
We performed a survey through social media. Participant demographics, skin condition before and after COVID-19, and the influence of adverse skin on social-psychological conditions were collected. We compared characteristics between individuals with or without acne exacerbation, and we performed a logistic regression to identify risk factors.Results
Six hundred and six participants (62.3%) responded the survey and 23.3% complained their facial acnes become exacerbated since COVID-19. The social-psychological impact of acnes is more prevalent in women. Risk factors for mask-related acne exacerbation were occupation as health-care workers (OR = 1.861, p = 0.027), prolonged wearing of N95 masks (OR = 3.167, p = 0.001), and touching of acnes (OR = 2.65, p = 0.002). Sex, pre-existed acnes, and prolonged wearing time per day are also associated with acne exacerbation.Conclusions
Mask-related adverse skin reactions are common in Orientals, and could lead to negative social-psychological effects. 相似文献6.

Background
Silver sulfadiazine is commonly used to treat local burn wounds. Aquacel-Ag is a hydrogen fiber dressing containing ionic silver that reduces burn wound infection and promotes antimicrobial activity. It is necessary to compare the efficacy of the two in the healing of burns.Aims
The aim of this study was to systematically evaluate the effect of Aquacel-Ag on burn wound healing.Methods
A computerized search of CNKI, VIP, Wanfang, SinoMed, PubMed, Cochrane Library, EMbase, Science Direct, Web of Science, Wiley Online Library, and Open Access Library databases was performed from January 1, 2000 to December 31, 2021 for randomized controlled clinical trials. The trials on Aquacel-Ag dressing and silver sulfadiazine in the treatment of burns were selected. Meta-analysis was performed using Review Manager 5.0 software.Results
Eleven articles were finally included, with 794 burn patients. Meta-analysis results showed that compared with patients treated with silver sulfadiazine, burn patients treated with Aquacel-Ag dressing had shorter wound healing time [MD = −2.49, 95% CI (−5.64–0.65), p = 0.12], significantly lower tumor necrosis factor-α (TNF-α) level [MD = −0.52, 95% CI (−0.82–0.22), p = 0.0008], higher wound healing rate [MD = 8.41, 95% CI (3.39–13.43), p = 0.001], fewer dressing changes [MD = −3.27, 95% CI (−4.90–1.63), p < 0.0001].Conclusion
Aquacel-Ag dressing can shorten wound healing time and effectively reduce inflammatory reactions in burn patients compared with silver sulfadiazine, but their safety still needs further exploration and analysis. 相似文献7.

Background
Acne has a high impact on patients being a chronic, common, and visible skin condition. Knowledge regarding treatment improves outcomes. The Cardiff Acne Disability Index (CADI) is commonly used in clinical practice for quality-of-life assessment. It has been validated in many languages, however, not in Romanian.Aims
To validate the Romanian adaptation of the CADI and educational materials for acne patients.Patients and Method
A 12-week prospective cross-sectional Web-based study, including 3rd- to 5th-year medical students attending our university was conducted. We obtained permission from the CADI copyright owner and performed the steps of the standardized translation process. The Romanian CADI adaptation was delivered online in a test–retest setup, during which participants were offered acne educational materials and completed a knowledge evaluation questionnaire.Results
A total of 95 complete answers were analyzed. The Romanian CADI adaptation showed good internal consistency, with Cronbach's α = 0.807 in the first application and Cronbach's α = 0.839 in the second. High test–retest reliability was observed, with interclass correlation coefficient ICC = 0.987 and Spearman's rank correlation coefficient rs = 0.970 for the overall CADI scores between the two administrations. The mean baseline score in the knowledge evaluation questionnaire was 15.52 points (±1.556), with a statistically significant improvement after exposure to the educational material (Z = −7.207, p < 0.001). This material was considered useful or very useful by 78(82.8%) participants.Conclusion
Romanian acne patients can benefit from CADI, a reliable and disease-specific tool for quality-of-life evaluation, together with validated, guideline-aligned educational material in their language. 相似文献8.

Introduction
Melasma is a human melanogenesis dysfunction that results in localized, chronic acquired hypermelanosis of the skin difficult to treat.Methods
This prospective, randomized, single-blind, study aimed to compare the efficacy and tolerability of a liposomal emulsion based on Politranexamide® (SAMPLE A) with that of a competitor based on acetylglucosamine, ethyl linoleate and phenyl ethyl resorcinol (SAMPLE B) in patients affected by facial melasma on 26 patients. Disease severity was assessed by the Melasma Area Severity Index (MASI) at baseline and after 6 and 12 weeks of therapy. All patients were subjected to photo documentation using DermaView camera and Antera 3D camera.Results
The mean MASI score at baseline was 10.93 ± 7 in the group A and 9.34 ± 6.29 in the group B, respectively. A significant decrease in MASI score from baseline was noted in both treatment groups as early as 6 weeks of follow-up (p = 0.00096 for SAMPLE A and p = 0.0049 for SAMPLE B) and was confirmed at the end of the treatment (p = 0.0006 for SAMPLE A and p = 0.00039 for SAMPLE B). Intergroup comparison revealed a greater improvement of melasma among patients in group A compared to those in group B that was quite statistically significant at weeks 6 (p = 0.055009) and significant after 12 weeks of follow-up (p = 0.032942). Both treatment groups experienced an improvement in Antera average level of melanin.Conclusion
Our results suggested Politranexamide® to be a useful and safe therapeutic option in treating melasma, more effective than competitor used in this study. 相似文献9.

Background
Melasma is a hyperpigmentary disorder causing cosmetic disfigurement. We aimed to compare the efficacy and safety of tranexamic acid (TXA) microinjections with TXA mesoneedling for facial melasma.Methods
This randomized assessor-blind split-face controlled trial included patients with symmetric facial melasma. One side of the face received TXA (100 mg/ml) mesoneedling and the other side intradermal TXA microinjections. The interventions were repeated three times with 4-week intervals (weeks 0, 4, and 8). The primary outcome was improvement in modified Melasma Area and Severity Index (mMASI) 4 weeks after the final treatment session. Secondary outcomes were complications and patient satisfaction with the treatments evaluated by a visual analog scale (VAS).Results
All 27 patients included in the study were female (mean age: 44.22 ± 8.39 years). Both groups were comparable in terms of mMASI scores before and after treatment (standardized mean difference [SMD] = 0.32, 95% confidence interval [CI] −0.22; 0.85, p = 0.248 and SMD = −0.13, 95% CI −0.66; 0.40, p = 0.633, respectively). The mMASI score change from baseline was not different (SMD = −0.39, 95% CI −0.93; 0.15, p = 0.157). However, patient satisfaction was significantly higher with TXA mesoneedling (SMD = 0.77, 95% CI 0.21; 1.32, p = 0.007). Post-inflammatory hyperpigmentation occurred in one patient in the TXA mesoneedling group. Erythema, scaling, and edema were significantly higher with TXA mesoneedling (p < 0.001).Conclusions
TXA mesoneedling was comparable with TXA microinjection in the treatment of facial melasma, while patient satisfaction was significantly higher with TXA mesoneedling; however, the high frequency of complications occurring with this treatment should be taken into account. 相似文献10.

Background
Despite a high frequency of dermatological general practice and emergency department presentations, including serious and potentially fatal skin conditions, evidence suggests that undergraduate dermatological education remains sparse. Given this, there exists a need to gauge dermatology-relevant knowledge and skill in our new doctors.Methods
An online survey was completed by final-phase medical students and junior doctors from Australian medical schools. The survey appraised self-perceived confidence of dermatology knowledge and skills, in addition to 5 knowledge-based multiple-choice questions.Results
Nine hundred and forty-two eligible responses were completed. Respondents reported low confidence in identifying dermatological conditions in people with skin of colour (μ = 1.69), handing over to dermatology colleagues (μ = 2.00) and in diagnosing and managing acute/emergency dermatology conditions (μ = 1.84). In contrast, participants felt most confident in counselling sun-protective behaviours (μ = 3.95) and suturing small wounds (μ = 3.43). 76.4% of respondents had not undertaken any dermatology placement, and 70.9% had never been formally assessed in dermatology. Those who received dermatology placement had a significantly higher aggregated self-reported confidence (p < 0.0001) and answered significantly more MCQs correctly (p = 0.0419). Those who had been formally assessed had a significantly higher self-reported confidence (p < 0.001) and answered significantly more MCQs correctly (p = 0.007).Conclusion
Final-phase medical students and junior doctors exhibit low confidence across many dermatology competencies. Participants believed they need more dermatology education, and seldom feel prepared when exposed to dermatologic pathologies. Introduction of a standardised curriculum, formal assessments and increased clinical exposure are possible solutions. 相似文献11.

Introduction
Palmar hyperhidrosis or excessive palmar sweating can reduce one's quality of life as it is associated with significant physical and occupational disabilities. We compared the gel and nanoemulgel of oxybutynin in treating these patients.Materials and Methods
This pilot study was performed as a double-blind controlled randomized clinical trial at Shahid Faghihi Hospital, Shiraz, Iran. In two randomly allocated groups of 15, patients diagnosed with primary palmar hyperhidrosis by an attending dermatologist applied half a fingertip (roughly 0.25 g) of 1% oxybutynin topical gel or 1% oxybutynin nanoemulgel to both palms every 12 h for one month. The Hyperhidrosis Disease Severity Scale (HDSS), Visual Analog Scale (VAS), and Dermatology Life Quality Index (DLQI) were used to assess the patients at the beginning and end of the study. Statistical analysis was performed using SPSS version 25.Results
The groups were similar in terms of age (p = 0.800), sex (p = 0.096), and baseline HDSS, VAS, and DLQI scores. The mean HDSS scores decreased significantly (p = 0.001) over time in patients receiving the gel (3.00 ± 1.00 vs. 2.33 ± 0.61) or nanoemulgel (2.92 ± 0.82 vs. 2.14 ± 0.53), without a significant difference between the groups. The same was true for the VAS and DLQI scores. Three patients in each group experienced transient, self-limited anticholinergic side effects (p = 0.983).Conclusion
Oxybutynin gel and nanoemulgel offer equal safety and similar efficacy in reducing the disease severity and increasing the quality of life of patients with palmar hyperhidrosis. 相似文献12.

Background
The risk of gout amid patients with acne keloidalis nuchae (AKN) has not been investigated in the past.Objective
To assess the risk of developing gout among patients with AKN relative to control subjects.Methods
A population-based retrospective study followed patients with AKN (n = 2677) and age-, sex-, and ethnicity-matched control subjects (n = 13 190). The incidence of new-onset gout was compared between the two groups. Hazard ratio (HR) for the risk of gout was obtained using a multivariate Cox regression model.Results
The incidence rate of gout was 1.12 (95% CI, 0.68–1.76) and 0.48 (95% CI, 0.34–0.66) per 1000 person-years among patients with AKN and controls, respectively. The crude risk of developing gout was significantly higher in patients with AKN (HR, 2.27; 95% CI, 1.26–4.10; p = 0.007). After controlling for age, sex, and ethnicity, AKN emerged as an independent risk factor of gout (adjusted HR, 2.34; 95% CI, 1.29–4.22; p = 0.005). When adjusting for other confounders such as body mass index, diabetes mellitus, hypertension, and dyslipidemia, the risk of gout in AKN fell out of significance (adjusted HR, 1.39; 95% CI, 0.73–2.65; p = 0.311),Conclusion
Patients with AKN experience an increased risk of gout. The risk is not independent and is mainly mediated through the metabolic comorbidities typifying AKN. We recommend screening for gout in patients with suggestive complaints. 相似文献13.
Background
Vitamin D receptor (VDR) polymorphisms may play an important role in the vitiligo susceptibility. There have been many studies looking at the associations between VDR polymorphisms and vitiligo risk, but the conclusions are still up for debate.Aim
This study aimed to determine whether polymorphisms in the VDR are associated to the susceptibility to vitiligo.Methods
Vitamin D receptor polymorphisms in vitiligo patients and controls were identified using PubMed/Medline and Embase databases. The relationships between the VDR ApaI, TaqI, BsmI, and TaqI polymorphisms and vitiligo were investigated using meta-analyses of all participants and Asian, Arab, European, and Latin American groups.Results
This meta-analysis included 13 papers with 2034 patients and 2771 controls. In all individuals, there was no link between vitiligo and the VDR ApaI A allele (OR = 0.889, 95% CI = 0.713–1.109, p = 0.298). However, in Asians (OR = 0.721, 95% CI = 0.553–0.940, p = 0.016) but not in Europeans or Arabs, there was a link between the VDR ApaI A allele and vitiligo. Utilizing recessive, dominant, and homozygote contrast models, a link between vitiligo and the VDR ApaI polymorphism was discovered in Asians. Meta-analysis of the VDR BsmI polymorphism showed a significant association between vitiligo and the B allele (OR = 0.812, 95% CI = 0.686–0.961, p = 0.015). In contrast, no connection between vitiligo and VDR polymorphisms was identified for TaqI and FokI polymorphisms.Conclusion
In the Asian population, ApaI and BsmI polymorphisms in VDR have been correlated to vitiligo susceptibility. However, TaqI and FokI polymorphisms in VDR are not associated with vitiligo susceptibility in European, Asian, Arab, and Latin American populations. 相似文献14.

Objectives
A microneedling pen has been cleared by the US Food and Drug Administration, indicated for improving the appearance of adult facial acne scars. The objective of this study was to assess the device's effectiveness for treating wrinkles of the face area.Materials and Methods
Healthy adults seeking to improve the appearance of face wrinkles were enrolled (N = 35), receiving four monthly microneedling procedures by a trained aesthetician who treated the face skin per manufacturer instructions. Wrinkle assessments were performed by two trained blinded raters by comparing baseline images of each subject with images obtained at 90 days post-procedure. Subsequently, the two raters were unblinded for the Clinician's Global Aesthetic Improvement Scale (CGAIS) assessment. Subjects completed the Subject's Global Aesthetic Improvement Scale (SGAIS) and a Satisfaction Questionnaire at 30 and 90 days post-treatment.Results
The study was completed by 32 subjects with a mean (SD) age of 56.3 (5.0) years. Wrinkle assessments demonstrated significant improvement in the face areas (p < 0.001). The SGAIS scores showed significant improvements after 30 and 90 days post-treatment (for each, p < 0.001). The CGAIS scores also showed significant improvements at 90 days post-treatment (p < 0.001). Most subjects reported some level of improvement in their appearance at 30 days (73.3%) and 90 days (68.8%) post-treatment. The satisfaction questionnaire showed high levels of improvement in wrinkles (93.8%), satisfaction with the treatment procedure (87.5%) and would recommend microneedling to friends and family members (80.6%) on the face and neck.Conclusion
Microneedling is a viable, minimally invasive option for treating wrinkles of the face. ClinicalTrials.gov Identifier: NCT03803059. 相似文献15.

Background
Pediatric allergic contact dermatitis (ACD) is increasingly prevalent. Patch testing is the gold-standard diagnostic method.Aims
Our study aimed to identify common contact-sensitizing allergens in Turkish children.Patients/Methods
We retrospectively analyzed the patch test results and characteristics of 191 pediatric patients [114 (59.7%) females, 77 (40.3%) males], who received the diagnosis of allergic contact dermatitis between 2015 and 2019.Results
The mean age of the patients was 12.2 years (range 4–18 years). Thirty-six (18.8%) of the patients in the study group had positive patch test outcomes with 56 positive allergens. Girls had a significantly higher rate of total positive patch test results than boys (75%/25%; p = 0.003, p < 0.05). The most frequent four allergens were nickel sulfate (n = 20, 10.4%), cobalt chloride (n = 6, 3.14%), p-phenylenediamine (n = 5, 2.61%), Methylchloroisothiazolinone/methylisothiazolinone (n = 5, 2.61%), respectively.Conclusions
In our study, we discovered that in addition to the frequently encountered metal allergens such as nickel and cobalt, p-phenylenediamine and Methylchloroisothiazolinone/methylisothiazolinone sensitivities were frequent in the Turkish population. p-phenylenediamine sensitization can cause serious systemic dermatitis during the lifetime of children. We suggest that in Turkey personal care and hygiene products containing Methylchloroisothiazolinone/methylisothiazolinone should be legally regulated. Since childhood contact dermatitis may have an impact on the quality of life by influencing family and social life, suspected allergens should be detected as early as possible. 相似文献16.

Background
Metabolic syndrome and insulin resistance may accompany rosacea. Zinc-alpha-2 glycoprotein (ZAG) is an adipokine involved in lipid, glucose, and insulin metabolism and might be associated with metabolic syndrome and insulin resistance.Aims
To investigate the serum ZAG levels, presence of metabolic syndrome, insulin resistance, and the correlation between ZAG levels, rosacea severity, and metabolic syndrome in patients with rosacea.Patients/Methods
Seventy-nine patients with rosacea and 80 healthy volunteers were included. Anthropometric and demographic features, personal and family histories, clinical data, the subtype, severity, and duration of rosacea were recorded. Metabolic syndrome, insulin resistance, and dyslipidemia were evaluated in both groups. Fasting blood sugar, lipid panel, C-reactive protein, sedimentation rate, insulin, and serum ZAG levels were investigated.Results
Frequency of metabolic syndrome, systolic and diastolic blood pressures, and C-reactive protein levels were significantly higher in the rosacea group (p < 0.001 and p = 0.001, respectively). Frequency of dyslipidemia and insulin resistance did not significantly differ between the groups (p = 0.175 and 0.694, respectively). The mean serum ZAG levels were lower in the rosacea group, but no significant difference was evident. In rosacea patients with metabolic syndrome, serum ZAG levels were significantly lower (p = 0.043); however, serum ZAG levels, insulin, and the homeostasis model assessment-estimated insulin resistance values were significantly higher (p = 0.168, 0.013 and 0.001, respectively).Conclusion
Metabolic syndrome, high blood pressure, and high C-reactive protein levels were associated with rosacea indicating chronic systemic inflammation. ZAG levels were associated with metabolic syndrome in patients with rosacea but not associated with rosacea subtype and disease severity. 相似文献17.

Background
Pain is considered the main limiting factor in carboxytherapy. Electroanalgesia has gained recognition in the field of dermatology and to date, only transcutaneous electrical nerve stimulation (TENS) has proved to be effective at reducing pain associated with carboxytherapy; however, the effect of medium frequency currents has yet to be investigated.Aims
Compare the effects of TENS, interferential current (IFC), and Aussie current on pain intensity associated with carboxytherapy and sensory comfort in the treatment of cellulite.Patients/Methods
Seventy-five women aged 18–49 years with moderate and/or severe gluteal cellulite were randomized into three groups: TENS (n = 25), IFC (n = 25), and Aussie current (n = 25), which underwent three sessions of carboxytherapy associated with an electrical current. Current amplitude was adjusted after each puncture, according to the maximum tolerance reported by participants, below the motor threshold. Pain intensity was measured using a numeric rating scale (0–10) and sensory comfort with the visual analogue scale (0–10).Results
There was no significant intergroup difference in pain intensity (p > 0.05) and sensory comfort (p = 0.502) during the application of carboxytherapy throughout the three treatment sessions.Conclusion
TENS, IFC, and Aussie currents showed no difference in pain intensity reduction and no current was found to be more comfortable. 相似文献18.

Background
Vitiligo is a skin disease characterized by a complex etiopathogenesis. Keratinocyte apoptosis may play a role in vitiligo pathogenesis. Aquaporin-3 (AQP-3) is an aqua-glyceroporin that controls keratinocyte proliferation and differentiation.Aim
To assess the immunohistochemical expression of AQP-3 in lesional and perilesional skin of vitiligo patients compared to healthy control skin.Methods
A total of 20 patients with generalized non-segmental vitiligo and 20 age- and sex-matched healthy controls were included. Lesional and perilesional skin of vitiligo patients, as well as normal skin of control subjects, were biopsied. The immunohistochemical expression of AQP3 in the epidermis was examined.Results
Compared to control skin, both lesional and perilesional skin showed a significant reduction in the intensity of membranous staining of AQP-3 (p < 0.001, p = 0.002, respectively). Moreover, the membrano-cytoplasmic pattern of AQP-3 staining was significantly detected in 80% of lesions and 85% of perilesional biopsies, while it was absent in control skin (p < 0.001). Additionally, nuclear AQP-3 expression was significantly detected in 35% of lesions and 55% of perilesional biopsies, while it was not detected in control skin (p = 0.012, p < 0.001, respectively). No statistically significant difference was detected between lesional and perilesional skin.Conclusions
To our knowledge, this is the first immunohistochemical research to show a significant abnormal nuclear expression of AQP-3 in lesional and perilesional skin of vitiligo patients. This abnormality may reflect impaired functions of AQP-3, leading to keratinocyte apoptosis with subsequent melanocyte death and development of vitiligo. 相似文献19.

Background
Knowledge of normal facial vascular variations could prevent catastrophic complications of cosmetic procedures as well as providing a guide for surgical planning. Color Doppler ultrasound is a safe and noninvasive method for real time vascular evaluation.Objective
The aim of this study was to evaluate the normal variations of the facial, angular, transverse facial, supratrochlear and supraorbital arteries in a sample of normal individuals.Methods
Normal individuals referred for dermal filler injection to the tertiary dermatologic center, were selected. Patients who were smoker or had a history of facial filler injection, facial surgery, or trauma were excluded from the study. Facial artery at three levels as well as angular, supratrochlear, supraorbital, and transverse facial arteries were evaluated by an 18 MHz ultrasound linear probe regarding their distance from facial reference lines and landmarks, and also their depths in various regions of face.Results
A total number of 43 individuals were evaluated in this study. Thirty-one (72.1%) were women. The number of absent facial artery was zero in level one, three (3.48%) in level two, and nine (10.46%) in level three. The angular artery was absent in 10 (11.62%) participants. The transverse facial artery was absent in 27 (31.39%) assessed individuals. Distance from reference lines at level 2 and 3 of facial artery and its depth at level 2 were significantly different between left and right side (p-values: <0.001, 0.01, and 0.03, respectively). No significant difference was seen between depth and distance of two sides for angular and transverse facial arteries. The comparison of the depths and distances from the reference lines of the assessed arteries between two sexes revealed only a significantly greater value of facial artery distance in level 1 in males (p-value: 0.001). BMI was also significantly correlated with the depth of facial artery in level 2 (Pearson correlation coefficient = 0.471, p-value = 0.002) and level 3 (Pearson correlation coefficient = 0.357, p-value = 0.03) and the distance of the facial artery in level 1 (Pearson correlation coefficient = 0.333, p-value = 0.029).Conclusions
Color Doppler ultrasound could be used to map the arteries of face to prevent vascular complications and safely guide cosmetic procedures. 相似文献20.
