The Ideal Chinese Lip: Impact of Lip Contours and Proportions.

BACKGROUND: The lips are one crucial determinant of facial attractiveness. Current studies investigating lip attractiveness were mostly conducted in Caucasians, and the results could not directly apply to Asians. Aside from lip proportions, lip contours play an important role in attractiveness but it is unclear how people perceive different lip contours. The aim of this study was to investigate the aesthetic perception of various lip shapes by Chinese to identify the most attractive lip morphology for women and men, respectively. METHODS: 303 Chinese participants were invited to rate the attractiveness of identical lip images with different contours and proportions in a young female and a young male. Stratified analyses were performed to assess the effect of gender, age and occupation on the preference of lip shapes. RESULTS: The lips that were rated to be most attractive had a flat upper vermilion border, an M-shaped oral fissure and a U-shaped lower vermilion border in both genders. Most respondents considered an upper-to-lower vermilion proportion of 1:1 to be more attractive, regardless of the gender of the lip models, and the lip thickness-to-width proportions of 1:2 and 1:2.5 were perceived most attractive for female and male, respectively. CONCLUSIONS: This study adds to our understanding of how lip contours contribute to attractiveness and that Chinese have distinctive aesthetic preferences for lip morphology, which possibly stem from racial characteristics and cultural differences. With such knowledge, practitioners may better tailor the treatment strategy when performing lip rejuvenation procedures.

Optical Analysis Method for Turbid Media Based on Wedge-Shaped Cells at Different Angles.

The wedge-shaped sample cell, by offering a comprehensive representation of scattering information in turbid media, significantly enhances the informational content conveyed by spectral images compared to flat sample cells. To further refine the accuracy of turbid medium component detection utilizing wedge-shaped sample cells, this work undertakes modeling and analysis of the influence of different wedge angles on detection precision. In this study, employing a 5° gradient in the incident angle of light, we investigate the impact of incident angles ranging from 10 to 45° on the turbid medium component analysis. Validation experiments are performed by utilizing solutions of Indian ink and fat emulsion at varying ratios. Experimental findings demonstrate that under identical experimental conditions, the wedge-shaped sample cell model at an incident angle of 35° yields optimal analysis results. Utilizing partial least-squares regression (PLSR) for the corresponding optical parameters, the highest value of Rp reached 0.980, with an RMSEP of 0.002. When compared to the model with a 30° incident angle, Rp increased by 0.033, and RMSEP decreased by 0.008. In comparison to the flat sample cell model, Rp increased by 0.041, and RMSEP decreased by 0.004. This study, through continuous variation of wedge angles and PLSR modeling and prediction, further enhances the accuracy of turbid medium component detection, laying an experimental foundation for subsequent analysis of turbid medium components based on wedge-shaped sample cells.

Automated 3D Perioral Landmark Detection Using High-Resolution Network: Artificial Intelligence-Based Anthropometric Analysis.

BACKGROUND: 3D facial stereophotogrammetry, as a convenient, non-invasive and highly reliable evaluation tool, has shown great potential in pre-operative planning and treatment efficacy evaluation of plastic surgery in recent years. However, it requires manual identification of facial landmarks by trained evaluators to obtain anthropometric data, which consumes large amount of time and effort. Automatic 3D facial landmark localization may facilitate fast data acquisition and eliminate evaluator error. OBJECTIVES: In this paper, we propose a novel deep-learning method based on dimension-transformation and key-point detection for automated 3D perioral landmark annotation. METHODS: The 3D facial model is transformed into 2D images on which High-Resolution Network is implemented for key point detection. The 2D coordinates of key points are then mapped back to the 3D model using mathematical methods to obtain the 3D landmark coordinates. This program was trained with 120 facial models and validated in 50 facial models. RESULTS: Our approach achieved satisfactory accuracy of 1.30 ± 0.68 mm error in landmark detection with an average processing time of 5.2 ± 0.21 seconds per model. And subsequent analysis based on these landmarks showed an error of 0.87 ± 1.02 mm for linear measurements and 5.62 ± 6.61° for angular measurements. CONCLUSIONS: This automated 3D perioral landmarking method could serve as an effective tool that enables fast and accurate anthropometric analysis of lip morphology for plastic surgery and aesthetic procedures.

The CrMYB33 transcription factor positively coordinate the regulation of both carotenoid accumulation and chlorophyll degradation in the peel of citrus fruit.

Citrus, cultivated extensively across the globe, possesses considerable economic importance and nutritional value. With the degradation of chlorophyll and accumulation of carotenoids, mature citrus fruits develop an orange-yellow peel, enhancing fruit value and consumer preference. MYB transcription factors (TFs) exert a significant role in diverse plant developmental processes and investigating their involvement in fruit coloration is crucial for developing new cultivars. This work aimed to characterize a citrus TF, CrMYB33, whose expression was found to be positively correlated with carotenoid biosynthesis during fruit ripening. The interference of CrMYB33 expression in citrus fruit resulted in inhibition of carotenoid accumulation, down-regulation of carotenoid biosynthetic genes, and a slower rate of chlorophyll degradation. Conversely, overexpression of CrMYB33 in tomato (Solanum lycopersicum) enhanced chlorophyll degradation and carotenoid biosynthesis, resulting in a deeper red coloration of the fruits. Furthermore, the transcription of associated genes was upregulated in CrMYB33-overexpressing tomato fruits. Additional assays reveal that CrMYB33 exhibits direct links and activation of the promoters of lycopene ß-cyclase 2 (CrLCYb2), and ß-carotene hydroxylases 2 (CrBCH2), both crucial genes in the carotenoid biosynthetic pathway. Additionally, it was found to inhibit chlorophyllase (CrCLH), a gene essential in chlorophyll degradation. These findings provide insight into the observed changes in LCYb2, BCH2, and CLH expression in the transgenic lines under investigation. In conclusion, our study revealed that CrMYB33 modulates carotenoid accumulation and chlorophyll degradation in citrus fruits through transcriptionally activating genes involved in metabolic pathways.

The role of the skin microbiome in wound healing.

The efficient management of skin wounds for rapid and scarless healing represents a major clinical unmet need. Nonhealing skin wounds and undesired scar formation impair quality of life and result in high healthcare expenditure worldwide. The skin-colonizing microbiota contributes to maintaining an intact skin barrier in homeostasis, but it also participates in the pathogenesis of many skin disorders, including aberrant wound healing, in many respects. This review focuses on the composition of the skin microbiome in cutaneous wounds of different types (i.e. acute and chronic) and with different outcomes (i.e. nonhealing and hypertrophic scarring), mainly based on next-generation sequencing analyses; furthermore, we discuss the mechanistic insights into host-microbe and microbe-microbe interactions during wound healing. Finally, we highlight potential therapeutic strategies that target the skin microbiome to improve healing outcomes.

Deciphering Depressor Anguli Oris for Lower Face Rejuvenation: A Prospective Ultrasound-Based Investigation.

BACKGROUND: The depressor anguli oris muscle (DAO) is a pivotal treatment target in creation of harmonic jawline. However, evidence of its live morphology remains scarce. OBJECTIVES: This study aimed to reevaluate DAO by a facile ultrasound analysis and hereby guide safer and more effective botulinum toxin type A (BTX-A) injection. METHODS: A prospective ultrasound assessment was conducted in 41 patients. Morphology of DAO and its relative position with neighboring structures were appraised at the ubiquitous facial landmark, labiomandibular fold (LMF). Three-dimensional images were captured before and after receiving BTX-A injection based on sonographic evidence. RESULTS: The skin-to-muscle depths of DAO on average (measured from the medial to lateral border) were 5.26, 5.61, and 8.42 mm. DAO becomes thinner and wider from zone 1 to 3 (p < 0.001). Overlapping lengths between DAO and DLI increased from zone 1 to 3: 4.74, 9.68, 14.54 mm (p < 0.001). The medial border of DAO was located at 4.33, 6.12, 8.90 mm medial to LMF (zone 1-3), and no muscle fibers of DAO was observed at zone 1 and 2 in near one-third of patients. Mouth corner downturn angle improvement upon receiving BTX-A injection at zone 2 and 3 were 88.3%, 32.3%, and 14.7% for the neutral, maximum smile, and down-pulling mouth corner expressions. CONCLUSIONS: This work established an informative ultrasound portrait of the DAO and structures in the perioral region, which suggests LMF as a convenient landmark to locate DAO. Injections at the middle and lower thirds of LMF at a 4-5 mm depth is recommended.

Comprehensive aesthetic corrections of gynecomastia using the reproducible safe and minimally invasive surgical strategy.

BACKGROUND: Minimally invasive access and fast recovery are trends of gynecomastia surgery. We placed great importance on liposuction and modified original pull-through technique. The purpose of this study was to present a refined surgical strategy for gynecomastia in grade I and II. METHODS: The refined strategy embraced enhanced liposuction to remove the intraglandular fat sufficiently, followed by open resection of gland using the pull-through and bottom-up technique with adjuvant liposuction in the end. Surgical data were recorded and satisfactory questionnaires with 5-point scales were administered during follow-up. RESULTS: Between January 2017 and May 2022, 165 patients underwent enhanced liposuction combined with the pull-through and bottom-up technique for gland excision. Age ranged from 12 to 56 years. The median length of surgery was 100 min. A median of 300 ml of fat was aspirated and a median of 20.8 g of gland was excised. Seventy-seven patients (46.7%) responded the questionnaires at least 6 months postoperatively, and the average overall satisfaction was 4.68 ± 0.52 points. Thirteen sides of breasts developed complications with a rate of 4.0%. CONCLUSION: Enhanced liposuction combined with pull-through and bottom-up technique proved effective to treat grade I and II gynecomastia with minimal scarring and high satisfaction. The refined strategy was simple and safe, and would obtain optimal outcomes even for inexperienced surgeons.

Protocol Establishment and Reliability Verification of Three-Dimensional Digital Stereophotogrammetry in Lower Eyelid Anthropometry.

BACKGROUND: Three-dimensional (3D) stereophotogrammetry has been widely used in anthropometry for both medical and esthetic purposes. However, no studies have assessed its reliability on measuring the lower eyelid by 3D imaging. This study aimed to establish a standardized 3D anthropometric protocol for lower eyelid region and validate its reliability. METHODS: Fifty-eight participants (116 eyes) were recruited with mean age of 39.14 ± 11.25 years. Two sets of VECTRA 3D images were taken for each subject, and each set of images was individually measured twice by two raters. Twenty-seven landmarks were identified in the lower eyelid region, and then 19 linear, 4 curvilinear, 7 angular and 2 areal metrics were assessed for intrarater, interrater and intramethod reliability. RESULTS: High reliability was found in this 3D imaging-based lower eyelid anthropometry. The mean absolute difference within 2 intrarater measurement were 0.22 and 0.08 units, the technical errors measurement were 0.31 and 0.15 units, the relative errors of measurement were 0.90% and 0.31%, the relative technical errors of measurement were 1.53% and 0.64%, and the intra-group correlation coefficient was 0.99 and 0.99. The results for interrater measurement were 0.53 units, 0.59 units, 2.94%, 3.41% and 0.96, and for intramethod measurement were 0.71 units, 0.77 units, 4.12%, 4.05% and 0.95 units, respectively. CONCLUSION: 3D stereophotogrammetry is reliable for lower eyelid anthropometry. The standardized protocol can be further applied for many purposes such as lower eyelid aging evaluation, surgical related assessment and periocular rejuvenation plan.

RUNDC1 inhibits autolysosome formation and survival of zebrafish via clasping ATG14-STX17-SNAP29 complex.

Autophagy serves as a pro-survival mechanism for a cell or a whole organism to cope with nutrient stress. Our understanding of the molecular regulation of this fusion event remains incomplete. Here, we identified RUNDC1 as a novel ATG14-interacting protein, which is highly conserved across vertebrates, including zebrafish and humans. By gain and loss of function studies, we demonstrate that RUNDC1 negatively modulates autophagy by blocking fusion between autophagosomes and lysosomes via inhibiting the assembly of the STX17-SNAP29-VAMP8 complex both in human cells and the zebrafish model. Moreover, RUNDC1 clasps the ATG14-STX17-SNAP29 complex via stimulating ATG14 homo-oligomerization to inhibit ATG14 dissociation. This also prevents VAMP8 from binding to STX17-SNAP29. We further identified that phosphorylation of RUNDC1 Ser379 is crucial to inhibit the assembly of the STX17-SNAP29-VAMP8 complex via promoting ATG14 homo-oligomerization. In line with our findings, RunDC1 is crucial for zebrafish in their response to nutrient-deficient conditions. Taken together, our findings demonstrate that RUNDC1 is a negative regulator of autophagy that restricts autophagosome fusion with lysosomes by clasping the ATG14-STX17-SNAP29 complex to hinder VAMP8 binding.

Heart failure in erythrodermic psoriasis: a retrospective study of 225 patients.

Purpose: Erythrodermic psoriasis (EP) is a severe form of psoriasis that affects multiple organs, including the cardiovascular system. However, few studies have focused on this condition.This study is aimed to assess the prevalence and factors associated with heart failure in EP patient, and to the measure the serum concentrations of fibroblast growth factor 23 (FGF23), a potential predictor of chronic heart failure. Methods: We retrospectively studied patients with EP hospitalized at Peking Union Medical College Hospital between January 2005 to October 2021. The prevalence of heart failure and associated factors was measured. In addition, peripheral blood samples were collected from 17 patients and matched with samples from eight healthy controls, and their serum concentrations of FGF23 were measured by ELISA. Results: We studied 225 patients with EP, with a male: female ratio of 2.7:1 and a mean age of 47.6 ± 16.7 years. Twenty-five (11.1%) participants were diagnosed with heart failure during their hospital stay. The patients with EP and heart failure were older (58.2 years vs. 46.2 years, p = 0.001); had a higher prevalence of a history of coronary heart disease (32.0% vs. 21.5%, p < 0.001), fever (48.0% vs. 23.0%, p = 0.007), infection (56.0% vs. 35.5%, p = 0.046); higher hsCRP concentration (43.2 mg/L vs. 8.2 mg/L, p = 0.005); and higher prevalence of anemia (60.0% vs. 22.0%, p < 0.001), hypoalbuminemia (64.0% vs. 42.0%, p = 0.037), and hyperlipidemia (40.0% vs. 20.0%, p = 0.023) than those without heart failure. The serum FGF23 concentration was significantly higher in patients with EP than controls (493.1 pg/ml vs. 277.8 pg/ml, p = 0.027), and was significantly lower after treatment (395.7 pg/ml vs. 463.1 pg/ml, p = 0.022). Conclusions: Clinicians should be aware of the risk of heart failure in patients with EP, and especially those of advanced age and with a history of coronary heart disease, severe systemic symptoms, high concentrations of inflammatory biomarkers, and poor nutritional status.

Gender- and Age-Related Characterization of Lip Morphology: A Three-Dimensional Analysis in a Chinese Population.

BACKGROUND: Establishing facial anthropometric reference values is essential for diagnosis of deformity, assessment of aging, and planning for aesthetic and reconstructive treatment. OBJECTIVES: This study aimed to provide detailed perioral anthropometric data in relation to sex and age in Chinese persons with a standardized 3-dimensional protocol. METHODS: Three-dimensional facial photographs were obtained of 60 male and 64 female healthy Chinese participants ages 20 to 35 and 50 to 65 years old, as well as 2 acromegaly patients, with the VECTRA 3D camera. A standardized evaluation was performed to locate 37 perioral landmarks and generate corresponding measurements, including 26 linear distances, 5 ratios, 2 curvatures, 4 areas, and 9 angles. Measurements of different age groups and of different genders were compared, as were measurements of healthy individuals with those of acromegaly patients. RESULTS: Sex discrepancy was noted in philtrum length, width, and area, lip width, and vermilion and cutaneous upper lip area; these were larger in Chinese males than females. However, vermilion heights were similar in both genders. With age, philtrum and cutaneous upper lip height and area, lip width, and angles related to cupid's bow significantly increased, whereas vermilion height and mouth corner angles decreased, and philtrum width, vermilion areas, and lip protrusion remained unchanged. Compared to healthy Chinese patients, acromegaly patients had a larger value for most measurements. Perioral rejuvenation based on detailed 3-dimensional anthropometry showed good results. CONCLUSIONS: Chinese males have wider but not thicker lips than females, and aging features thin, flattened, and wide vermilions with a lengthened philtrum in both genders. These data can serve as a reference standard for disease diagnosis, aesthetic procedures, and reconstructive lip surgeries.

A Quantitative Three-Dimensional Tear Trough Deformity Assessment and Its Application in Orbital Septum Fat Transposition.

BACKGROUND: Existing evaluation tools of tear trough deformity are based on subjective impression of clinicians. More accurate quantitative assessment methods are needed. This study aimed to propose a quantitative three-dimensional assessment method for the tear trough deformity in comparison with the Barton's grading system and apply it to the efficacy evaluation of orbital septum fat transposition. METHODS: 117 healthy Chinese adults (234 eyes) were enrolled and divided into four groups according to the Barton's grading system. Three-dimensional facial images were captured using Vectra H1 handheld camera. 6 anthropometric landmarks were identified on each eye and 8 linear measurements were generated accordingly. Intra-observer reliability was determined and measurements were compared between groups. Pre- and post-operative three-dimensional measurements were compared in 19 patients who received lower blepharoplasty with orbital septum fat transposition. RESULTS: The severity of tear trough was positively correlated with age (P < 0.001) but not BMI (P = 0.145) or gender (P = 0.280). Intra-rater reliability of the 8 linear measurements was excellent except for the vertical distance between the palpebrale inferioris margin and the tear trough below the pupillary center. Intergroup comparison showed that the horizontal distance between the lateral end of tear trough (P < 0.001) and medial canthus and the sagittal vector from tear trough point toward eyelid bag point (P = 0.009) increased with grade, while the vertical distance from mid-pupil to palpebrale inferioris margin decreased gradually (P = 0.001). Orbital septum fat transposition significantly improved the tear trough deformity as assessed by these three-dimensional measurements. CONCLUSIONS: We demonstrated a novel quantitative evaluation method of the tear trough deformity using three-dimensional stereophotogrammetry and proved it to be valid and reliable. It showed good value of clinical application and might help with periorbital rejuvenation planning and outcome assessment.

Development and Validation of a Comprehensive Perioral Evaluation Method Using Three-Dimensional Stereophotogrammetry.

BACKGROUND: The non-invasive three-dimensional (3D) stereophotogrammetry is widely used in anthropometry for medical purpose. Yet, few studies have assessed its reliability on measuring the perioral region. OBJECTIVES: This study aimed to provide a standardized 3D anthropometric protocol for the perioral region. METHODS: 38 female and 12 male Asians were recruited (mean age 31.6 ± 9.6 years). Two sets of 3D images using the VECTRA 3D imaging system were acquired for each subject, and two measurement sessions for each image were performed independently by two raters. 25 landmarks were identified, and 28 linear, 2 curvilinear, 9 angular and 4 areal measurements were evaluated for intrarater, interrater, and intramethod reliability. RESULTS: Our results showed high reliability of 3D imaging-based perioral anthropometry by mean absolute difference (0.57 and 0.57 unit), technical error measurement (0.51 and 0.55 unit), relative error of measurement (2.18% and 2.44%), relative technical error of measurement (2.02% and 2.34%), and intraclass correlation coefficient (0.98 and 0.98) for intrarater 1 and intrarater 2 reliability; respectively 0.78 unit, 0.74 unit, 3.26%, 3.06% and 0.97 for interrater reliability; and respectively 1.01 unit, 0.97 unit, 4.74%, 4.57% and 0.95 for intramethod reliability. CONCLUSIONS: This standardized protocol utilizing 3D surface imaging technologies are feasible and highly reliable in perioral assessment. It could be further applied for diagnostic purpose, surgical planning and therapeutic effect evaluation in clinical practice in relation to perioral morphologies.

Direct bilirubin: A predictor of hematoma expansion after intracerebral hemorrhage.

BACKGROUND: Previous evidence demonstrated that several biomarkers involved in the pathological process of coagulation/hemostasis dysfunction, impairment of brain vascular integrity and inflammation are associated with hematoma expansion (HE) after intracerebral hemorrhage (ICH). We aimed to explore whether there were unreported laboratory biomarkers associated with HE that were readily and commonly available in clinical practice. METHODS: We retrospectively analyzed consecutive acute ICH patients from 2012 to 2020 with admission laboratory tests and baseline and follow-up computed tomography (CT) scans. Univariate and multivariate regression analyses were used to evaluate associations between conventional laboratory indicators and HE. The results were verified in a prospective validation cohort. The relationship of candidate biomarker and 3-month outcomes was also investigated and mediation analysis was undertaken to determine causal associations among candidate biomarker, HE and outcome. RESULTS: Of 734 ICH patients, 163 (22.2%) presented HE. Among the included laboratory indicators, higher direct bilirubin (DBil) was associated with HE (adjusted odds ratio [OR] of per 1.0 µmol/L change 1.082; 95% confidence interval [CI] 1.011-1.158). DBil >5.65 µmol/L was a predictor of HE in validation cohort. Higher DBil was also associated with poor 3-month outcomes. The mediation analysis indicated that the association of higher DBil and poor outcomes was partially mediated by HE. CONCLUSIONS: DBil is a predictor of HE and poor 3-month outcomes after ICH. DBil's metabolic process and involvement in the pathological mechanism of HE are likely to contribute to the association between DBil and HE. Interventions targeting DBil to improve post-ICH prognosis may be meaningful and worthy of further exploration.

Systemic monotherapy with acitretin for erythrodermic psoriasis: results of a retrospective study of 81 patients.

Background: Erythrodermic psoriasis (EP) remains challenging to manage because it is rare and has complex complications. Although acitretin is recommended as an appropriate choice for EP, there is a lack of large-scale evidence. Objectives: This study aims to assess the efficacy and safety of acitretin as systemic monotherapy in EP patients. Design: We retrospectively analyzed data from patients with EP who received at least 3 months of acitretin as systemic monotherapy during hospitalization and out-patient follow-up from January 2005 to May 2021 at the Peking Union Medical College Hospital, China. Methods: The efficacy was clinically evaluated after 1, 2, 4, and 12 weeks of treatment, which was classified as a good response (>75% of lesions cleared), partial response (50%-75% cleared), moderate response (25-50% cleared), or no response (<25% cleared). Safety was assessed on the basis of physical examination results and significant changes in laboratory examination results after 12 weeks of treatment. Results: Overall, 81 patients (79.0% men; mean age, 47.9 years) were included. The acitretin dose ranged from 20 to 60 mg/day (0.3 to 0.8 mg/kg/day). The rates of good, partial, and moderate responses were 0.0%, 2.5%, and 42.0% at 1 week; 3.7%, 34.6%, and 61.7% at 2 weeks; 29.6%, 58.0%, and 12.4% at 4 weeks; and 85.2%, 13.6%, and 1.2% at 12 weeks after treatment initiation, respectively. EP patients transformed from psoriasis vulgaris showed a higher good/partial response rate compared with that of EP patients that developed from pustular or articular psoriasis (44.6% vs. 14.3%, p = 0.035). Patients with concurrent infection showed a lower rate of good/partial response compared with that of those without concurrent infection (16.7% vs. 44.4%, p = 0.049). Adverse effects were seen in 45 (55.6%) patients in 12 weeks, and dyslipidemia (n = 31; 38.3%), xerosis (n = 24; 29.6%), and elevated liver enzymes (n = 6; 7.4%) were most commonly reported. Twenty-three patients were followed up for over 3 years, and six (26.1%) patients had EP recurrence. Conclusions: Acitretin as a systemic monotherapy showed satisfactory effectiveness for EP, especially in patients developed from psoriasis vulgaris and without infection.

Efficacy and safety of the combined use of ipilimumab and nivolumab for melanoma patients with brain metastases: a systematic review and meta-analysis.

CONTEXT: Immune checkpoint inhibitors have advanced immunotherapy for melanoma patients.Objective: This study evaluates efficacy and safety of ipilimumab and nivolumab combination (IN) for melanoma brain metastases (MBM) patients. MATERIALS AND METHODS: Literature search was conducted in electronic databases and studies were included if they reported efficacy and safety of IN in MBM patients or prognostic information related to brain metastases. Outcomes evaluated were objective response rate (ORR), complete remission/stable disease/progressive disease rates, progression-free survival (PFS), overall survival (OS), incidence rates of adverse events, and hazard ratios of disease progression or mortality between IN-treated patients with and without brain metastasis. RESULTS: Intracranial ORR was higher in IN-treated MBM patients than with control therapies (nivolumab or ipilimumab plus fotemustine). IN treatment led to longer PFS and OS in than control treatments. Five-year OS of IN-treated MBM patients was up to 51% compared to 34% for nivolumab. Outcomes were better for treatment naïve and asymptomatic patients. Whereas many studies reported significantly higher mortality or progression risk with IN treatment in MBM patients compared to non-MBM melanoma patients, many others did not find this risk significant. Incidence of grade 3/4 adverse events in IN-treated MBM patients was: diarrhea or colitis (16%), hepatitis (15%), rash (8%), increased alanine transaminase (8%), increased aspartate aminotransferase (7%), increased lipase (6%), increased amylase (4%), fatigue (3%), hypophysitis (2%), pneumonitis (2%), headache (2%), nausea or vomiting (1%), and neutropenia (1%). CONCLUSION: IN is an efficacious and safer treatment option for MBM patients, especially for asymptomatic and treatment naïve patients.

Labiaplasty in Adolescents: Indications and Treatment Protocol.

BACKGROUND: Adolescents constitute a unique group of labia minora hypertrophy patients, but the necessity and benefits of labiaplasty for adolescents remain controversial. OBJECTIVES: The purpose of this study was to summarize the surgical indications, the details of the treatment procedure, postoperative complications, and therapeutic outcomes of labiaplasty in the adolescent population. METHODS: A retrospective chart review was performed of adolescent patients aged <18 years old who underwent labiaplasty between January 2016 and May 2022. Patient characteristics, surgical method, concomitant procedures, procedure side, operative time, complications, and follow-up data were recorded. RESULTS: A total of 12 patients aged <18 years were included in this study. All procedures were performed for functional reasons. The mean [standard deviation] operative time was 61.75 [20.77] minutes (range, 38-114 minutes). Unilateral labia minora hematoma within 24 hours occurred in 2 of the 12 patients (16.7%) and surgical evacuations were performed immediately. All patients were followed up electronically at 42.33 [16.88] months (range, 14-67 months). Notably, 83.33% (10/12) of patients reported being very satisfied, and 16.67% (2/12) of patients were satisfied. There was no patient dissatisfaction. Preoperative discomfort was completely resolved in 9 patients (75.00%) and significantly improved in 3 patients (25.00%). Furthermore, no patients indicated that symptoms were not improved or made worse. CONCLUSIONS: In the adolescent population, severe hypertrophy of the labia minora and the clitoral hood will cause discomfort, affecting the quality of life and mental health. Therefore, labiaplasty is a safe and effective procedure in adolescents to improve genital appearance and quality of life.

Associations between bullous pemphigoid and hematological diseases: Literature review on mechanistic connections and possible treatments.

Bullous pemphigoid is an autoimmune blistering disorder that primarily occurs in elderly patients. Reports indicate that BP coexists with various hematological diseases, including acquired hemophilia A, hypereosinophilic syndrome, aplastic anemia, autoimmune thrombocytopenia, and hematological malignancies. Early identification of these comorbidities contributes to a better control and reduced mortality. This article details the atypical clinical manifestations of BP when associated with hematological diseases, specific diagnostic strategies, underlying mechanistic connections, and possible treatments. Cross-reactivity between autoantibodies and exposed abnormal epitopes, shared cytokines and immune cells, together with genetic susceptibility are the most common connections between BP and hematological diseases. Patients were most often successfully treated with oral steroids combined with medications specifically targeting the hematological disorders. However, the individual comorbidities require specific considerations.
