The Characteristics and Inheriting Pattern of Skin Aging in Chinese Women: An Intergenerational Study of Mothers and Daughters.

Introduction: The aging of the skin, which is affected by both external and internal causes, can reflect the external age and the internal health status. While the aging characteristics differ across ethnic groups, the specific changes in skin aging within the Chinese population have been underexplored. Moreover, investigating the similarity of aging skin characteristics between parent-offspring pairs remains uncharted territory. This study aims to fill these gaps by examining the skin aging features of Chinese women and assessing the similarity in aging skin characteristics between mother-daughter pairs. Methods: A total of 40 mother-daughter pairs were recruited and analyzed. The perceived ages of the participants were evaluated, and their aging skin traits were systematically graded. Statistical methods were employed to discern the trends of the aging skin characteristics. By introducing a novel similarity parameter, we compared whether various skin aging characteristics have similar patterns between mothers and daughters. Results: Our findings indicate that age 50 represents a pivotal point in skin aging. Beyond this age, the increase in rhytides and laxity scores accelerated noticeably, whereas the escalation in dyschromia scores became less marked. By introducing similar parameters between mother-daughter pairs and the radar map, we discovered that the skin aging characteristics are remarkably consistent between mother-daughter pairs. Conclusion: Understanding the main aging skin characteristics of different age groups can allow caregivers to devise treatments for preventing skin aging in women of various ages. The mother's skin aging trend is also significant for the daughter's skin aging prevention.

Skin aging, a complex process influenced by both internal and external factors, exhibits distinct patterns across ethnic groups. Despite this, the specific aging characteristics within the Chinese population and the hereditary similarities between parents and offspring have not been thoroughly investigated. To address this gap, our study focused on the skin aging features of Chinese women and explored the resemblance in these features between mother-daughter pairs. Eighty-seven women from the same community, including 40 mother-daughter pairs, participated in our study. We assessed how old each participant appeared to be and methodically evaluated their skin aging signs by a modified scale. With the introduction of a new similarity parameter, we further examined the extent to which skin aging traits showed parallel trends between mothers and their daughters. Our findings pinpoint age 50 as a pivotal moment in the skin aging trajectory, where the increase in wrinkles and skin laxity becomes more pronounced, contrasting with a deceleration in skin discoloration. Remarkably, a consistent pattern of aging characteristics was observed between mother-daughter pairs, suggesting a potential genetic influence. This study not only sheds light on the specific skin aging patterns among Chinese women but also underscores the significance of genetic factors in shaping these patterns. The insights gained pave the way for developing targeted interventions for skin aging prevention and treatment, emphasizing the importance of considering familial aging trends.

Clinical and pathological evaluation of cladribine treatment response in a case series of patients with xanthoma disseminatum.

BACKGROUND: Xanthoma disseminatum (XD) is a rare form of non-Langerhans histiocytosis with extensive cutaneous involvement. There is a paucity of evidence-based recommendations for treatment decision-making. Previous case reports have established purine analogues, especially cladribine, as a hopeful first-line treatment option, but characterization of the clinical and pathological responses is lacking. OBJECTIVES: To characterize the clinical and pathological responses to cladribine monotherapy based on serial examinations in XD patients. MATERIALS & METHODS: We retrospectively studied the clinical, pathological and laboratory data in a cohort of five XD patients who received intravenous cladribine monotherapy with serial examinations in our hospital. Compared with baseline characteristics, changes in clinical features and pathological patterns were identified and analysed. We also conducted a literature review of reported cases of cladribine treatment in XD patients. RESULTS: Four male and one female patient were involved in the study. All patients demonstrated satisfactory clinical responses to cladribine monotherapy after 5 to 10 cycles. We observed a pathological shift in pattern from classic xanthogranuloma to transitional fibrohistiocytic infiltration during the treatment, and pathological responses heralded persistent clinical improvement. Other than afebrile neutropenia, no prominent adverse events were identified. Sustainable lesion clearance was achieved in all five patients during the follow-up period, ranging from 19 to 66 months. CONCLUSION: Cladribine monotherapy is an effective and well-tolerated therapeutic option for XD patients. Pathological transformation is a signature of the clinical response and possibly unveils the underlying histiocyte biology of diseases in the xanthogranuloma family.

The Association between Sugar-Sweetened Beverages and Male Pattern Hair Loss in Young Men.

We performed this study to investigate the association between sugar-sweetened beverage (SSB) consumption and male pattern hair loss (MPHL) in young men. We conducted this cross-sectional study from January to April 2022 in mainland China. Young people aged 18-45 years (n = 1951) were recruited from 31 provinces in China. We used a self-reported online survey for data collection. We explored the associations between the amount/frequency of SSB consumption and MPHL by using a binary logistic regression model, with adjustments for sociodemographic, hair status, dietary intake, lifestyle, and psychological factors. Among the 1028 participants (27.8 ± 7.2 years) in the final analysis, we found that high SSB consumption is associated with a higher risk of MPHL. We recommend more support to decrease SSB consumption among young people to minimize negative health outcomes.

A proposed scoring system for facial port-wine stain evaluation: Facial port-wine stain area and severity index.

BACKGROUND: Port-wine stain (PWS) is a congenital capillary malformation that often occurs on the face. Feasible and quantitative evaluation of facial port-wine stain (FPWS) can significantly impact its clinical management and aid in future research. AIM: To develop and validate an easy-to-use scoring system for FPWS evaluation. METHODS: A facial port-wine stain area and severity index (FSASI) scoring system was proposed. To determine the FSASI score, the face was divided into four regions: forehead, right malar, left malar, and perioral. The severity of FPWS in each region was evaluated by three factors: percentage of the area affected, lesion color, and thickness. To evaluate the intra- and inter-rater reliability of FSASI, two separate FSASI assessments on 111 clinical pictures were conducted by each rater in a one-week interval, and the results from 6 independent raters at different time points were compared. Validity of the FSASI scores was assessed by comparing it with physician global assessment (PGA) and traditional classification data. Validity of the area and color elements of FSASI was also determined. The changes in FSASI scores after vascular-targeted photodynamic therapy (V-PDT) were analyzed to evaluate the treatment effect. RESULTS: The FSASI scoring system showed good intra- and inter-rater reliability (ICC >0.75, p < 0.001) and was found to be comparable to PGA scores (Spearman's r = 0.752-0.907, p < 0.001) and traditional classification data (Spearman's r = 0.426-0.662, p < 0.001). Efficacy analysis indicated that FSASI scores decreased after V-PDT treatment. CONCLUSION: The results of this study demonstrated the reliability and validity of FSASI, which may be applied to assess the severity of FPWS and to evaluate treatment effects in clinical practice and research.

A Comparison of Efficacy and Safety of Fractional Carbon Dioxide Laser and Fractional Er:YAG Laser for the Treatment of Xanthelasma Palpebrarum: A Two-Center Randomized Split-Face Controlled Trial.

Background: Xanthelasma palpebrarum (XP) is a form of cutaneous xanthoma that presents as collections of yellowish papules or plaques around the eyelids or canthus, affecting patients cosmetically. Objective: This study aimed to compare the efficacy and safety of fractional carbon dioxide (CO2) laser to that of fractional Er:YAG laser for the treatment of XP. Methods: Two centers recruited patients diagnosed with XP of bilaterally symmetrical lesions. The lesion on one side was randomly assigned to be treated with fractional CO2 laser while the lesion on the other side was treated with fractional Er:YAG laser. All subjects received up to five treatments, with a 4-week interval between each treatment. Results: Thirty-nine patients completed the study and a total of 82 lesions were available for final assessment. The percentage of "Excellent Improvement" on third and fourth visit was 60.98% versus 39.02% and 90.24% versus 63.41%, respectively, p < 0.05. In a follow-up for 12 to 25 months, the number of lesions recurred on the side treated with fractional CO2 laser and fractional Er:YAG laser are 9 (22%) and 10 (24%), respectively. Conclusions: In this study, fractional CO2 laser therapy appears superior since a fewer treatments are required for patients to show significant clinical improvement.

Epidermoid cyst removal with CO2 laser fenestration: A retrospective cohort study.

BACKGROUND: Epidermoid cyst (EC) is a common and benign tumor, which can occur anywhere on the skin. Surgical excision is usually considered as the first-line treatment. However, linear scars arising after excision for EC remain a cosmetic problem. OBJECTIVE: To evaluate the efficacy and safety of EC removal assisted with CO2 laser fenestration. METHODS: All patients diagnosed with EC and treated with CO2 laser fenestration, content extrusion, and removal of the cyst wall between January 1, 2016, and December 31, 2018, were included in this study. After a follow-up period ranging from 6 to 27 months, scarring, recurrence, complications, and satisfaction were assessed and analyzed. RESULTS: Forty-three of the 47 patients have been cured by a single operation. The recurrence rate was 8.5%, which was not significantly correlated with tumor sizes or locations. 46.8% of the patients had no obvious scar after treatment. No infections or complications were observed in any of these cases. 89.4% of the patients were satisfied with the effectiveness of the treatment, while 95.7% and 87.2% were satisfied with the comfort and the cosmetic results, respectively. CONCLUSIONS: CO2 laser fenestration-assisted removal procedure is effective for the treatment of ECs with good aesthetic outcome.

Quality of life of adult vitiligo patients using camouflage: A survey in a Chinese vitiligo community.

BACKGROUND: Vitiligo is an acquired depigmented skin disease resulting in white macules, which may significantly impair the quality of life (QoL) of the patients. OBJECTIVE: To estimate the QoL in Chinese vitiligo patients using camouflage with a more detailed description, and to identify the possible risk factors related to poor QoL. METHODS: An online survey was conducted in vitiligo patients using camouflage from a vitiligo community. Survey questions included demographic, clinical information, dermatology- and vitiligo-specific QoL questionnaires. Multivariate logistic analysis was performed to identify risk factors that related to poor QoL. RESULTS: In total, 884 respondents were included in the analyses, of which 413 (46.7%) were male. The score of DLQI was 5.83±5.75 (mean± SD). Age, gender, marriage status, occupational status, anogenital involvement, patient-perceived severity (presented by VAS score), symptoms as itching, pain, sunburn and koebner phenomenon, total cost of treatment and degree of satisfaction in camouflage therapy were independently associated with DLQI score (p<0.05). CONCLUSION: Vitiligo has considerable impact on QoL of affected patients in Chinese population even when they were using camouflage. Camouflage might be helpful to improve QoL of the patients.
