Smart Use of Skin Biopsy Punch in Treating Keloids: A Single-Center Retrospective Study.

BACKGROUND: Treatment of scarring has long been a problem due to high incidence and recurrence. Despite many existing treatment therapies, the efficacy remains unstable. OBJECTIVES: To determine the efficacy and safety of skin biopsy punch in combination with corticosteroid injection (BPCI) in treating keloids. APPROACH: This was a retrospective study. In total, 16 patients with keloids received BPCI. Changes in scar appearance, accompanied symptoms, and Vancouver Scar Scale (VSS) were analyzed. Patient satisfaction, VAS scores, and adverse effects were also evaluated. RESULTS: Scar appearance, accompanied symptoms, and VSS scores improved significantly after the treatment. The total effective rate was 93.75% at an 18-month follow-up on average. The mean reduction rate of VSS score was 58.44% (p < 0.0001), especially in height and pliability (84.44% and 78.19%, p < 0.0001). The recurrence rate in this study was 12.5% (n = 2) at an 18-month follow-up on average. Mild adverse effects of pain, pruritus, hypopigmentation, and telangiectasia were recorded. CONCLUSIONS: This study demonstrated BPCI might be an effective and safe therapy in keloids with a low long-time recurrence rate and well tolerance for patients.

An Open-Label, Uncontrolled, Single-Arm Clinical Trial of Tofacitinib, an Oral JAK1 and JAK3 Kinase Inhibitor, in Chinese Patients with Keloid.

BACKGROUND: The keloid treatment is still a thorny and complicated clinical problem, especially in multiple keloids induced by wound, severe burn, ethnic background or cultural behaviors, or unexplained skin healing. Mainstream treatments have limited efficacy in treating multiple keloids. As no oral treatment with painlessness and convenience is available, oral treatment strategies should be formulated. OBJECTIVES: This study aimed to investigate the efficacy and therapeutic mechanism of oral tofacitinib in keloid patients. METHODS: We recruited the 7 patients with keloid scars and prescribed 5 mg of tofacitinib twice a day orally with a maximum follow-up of 12 weeks. The Patient and Observer Scar Assessment Scale (POSAS), the Vancouver scar scale (VSS), ANTERA 3D camera, and the DUB Skin Scanner 75 were used to assess the characteristics of the lesion. Immunohistochemistry was performed to evaluate collagen synthesis, proliferation, and relative molecular pathways. Moreover, the effects of tofacitinib were assessed on keloid fibroblast in vitro. RESULTS: After 12 weeks of oral tofacitinib, significant improvement in POSAS, VSS, and Dermatology Life Quality Index (DLQI) scores was observed (p < 0.05). The volume, lesion height, and dermis thickness of the keloid decreased (p < 0.05). Moreover, significant decreases in the expression of collagen I, Ki67, p-STAT 3, and p-SMAD2 were observed after 12 weeks of administration. In vitro experiments suggested that tofacitinib treatment inhibits fibroblast proliferation and collagen I synthesis via suppression of STAT3 and SMAD2 pathway. CONCLUSION: Tofacitinib, a new candidate oral drug for keloid, could reduce keloid lesion volume by inhibiting collagen synthesis and inhibiting fibroblast proliferation, and alleviate itch and pain to obtain a better life quality.

Dermabrasion combined with photodynamic therapy: a new option for the treatment of non-melanoma skin cancer.

Non-melanoma skin cancer (NMSC) is the most common malignancy. Photodynamic therapy (PDT) is effective for the treatment of certain NMSCs. However, the clinical response rates of some NMSCs to single PDT are still far from ideal. The reason may be that PDT has shown limited efficacy in managing thicker NMSCs. To explore the efficacy and safety of dermabrasion combined with PDT (D-PDT) for the treatment of NMSCs. This was a retrospective, single-arm, multi-centre study. In total, 172 tumours from 40 patients were treated with D-PDT during the study period. The mean follow-up period was 40 months (range 15-110 months). D-PDT was performed with 633-nm red light at 80 m W/cm2 after lesion dermabrasion and 4 h of photosensitizer exposure. Six nodular basal cell carcinomas (nBCCs) from 6 patients, 9 squamous cell carcinomas (SCCs) from 9 patients, 17 Bowen diseases (BDs) from 10 patients and 140 actinic keratoses (AKs) from 15 patients treated with D-PDT were examined in this study. Only two patients with three AKs experienced recurrence over 12 months. The mean final follow-up periods of patients with AKs, BDs, nBCCs and SCCs were 30, 33, 45 and 60 months, respectively. Thirty-four of the 40 patients treated with D-PDT reported excellent or good cosmetic results. The mean Dermatology Life Quality Index (DLQI) scores of the patients improved significantly after treatment (estimated MD 9.72 [95% CI 8.69 to 10.75]; p < 0.001). D-PDT is a safe, cosmetic and effective treatment that could be a new candidate therapeutic for NMSC.

Transfemoral versus Transapical Aortic Implantation for Aortic Stenosis Based on No Significant Difference in Logistic EuroSCORE: A Meta-Analysis.

Background Transcatheter aortic valve implantation (TAVI) has gained increasing acceptance for patients with severe aortic stenosis (AS). The present meta-analysis was performed to assess if the transapical (TA) approach has any benefit in reduction of mortality and complications relative to the transfemoral (TF) approach for patients with AS. Methods All relevant studies comparing TF-TAVI and TA-TAVI from January 2002 to November 2013 were retrieved from Medline and Embase databases. The relative risk (RR) and 95% confidence interval (CI) were used to evaluate the difference between two groups. Heterogeneity assumption was assessed by an I (2) test. The random-effect model or fixed-effect model was used to estimate summary effect based on I (2) test. Results Nine studies conformed to the predefined criteria, including 666 patients in the TF-TAVI group and 457 patients in the TA-TAVI group. No difference was found in all-cause mortality at 30 days and beyond 1 year between the two groups (30 days: 9.2% versus 11.4%; RR, 0.72; 95% CI, 0.47 to 1.11; p = 0.14 and beyond 1 year: RR, 0.96; 95% CI, 0.59 to 1.56; p = 0.86). There was a trend toward increased incidence of stroke in patients in the TF-TAVI group (4.7% versus 2.6%; RR, 1.64; 95% CI, 0.75 to 3.58; p = 0.21), and the incidence of vascular complication and postoperative heart block were significantly increased in patients having TF-TAVI (vascular complications: 14.7% versus 7.1%; RR, 2.04; 95% CI, 1.15 to 3.61; p = 0.01 and heart block: 13.4% versus 4.6%; RR, 2.53; 95% CI, 1.10 to 5.83; p = 0.03). Additionally, more patients in the TF-TAVI group required permanent pacemaker relative to the TA-TAVI group (10.8% versus 3.4%; RR, 2.74; 95% CI, 1.41 to 5.32; p = 0.003). Conclusions Among patients with AS with no significant difference in logistic EuroSCORE, TA-TAVI has a lower risk of vascular complication and postoperative heart block but a similar incidence of stroke and mortality compared with TF-TAVI. Accordingly, TA approach is a promising and feasible option for the patients with severe AS.

Comprehensive Treatment of a Rare Case of Complete Primary Pachydermoperiostosis with Large Facial Keloid Scars: A Case Report and Literature Review.

Introduction: Pachydermoperiostosis (PDP), or primary hypertrophic osteoarthropathy, is a rare autosomal dominant disease with primary clinical features of pachydermia (thickening of skin) and periostosis (new bone formation). Keloid scar formation is also rather obscure, and some scientists have claimed that keloid scars contain an excessive amount of fibroblasts compared with normal skin as well as a dense mass of irregularly deposited connective tissues. Case Presentation: A 25-year-old man exhibited extensive skin folding on his face, a gyrus-like scalp, depressed nasolabial folds, and keloids. Symptoms began at 18 years of age, progressing insidiously. Additionally, he experienced clubbing of fingers and toes, joint pain, muscle soreness, and hyperhidrosis. Radiographic examinations revealed thickened bone and cystic regions. Diagnosed with complete primary PDP and facial keloid scars, he underwent skin dermabrasion, biopsies, and a comprehensive treatment involving, botulinum toxin injections, 5-fluorouracil, and a carbon dioxide lattice laser. Conclusion: PDP presents challenges due to its unclear etiology but stabilizes over time in most cases. Comprehensive treatment strategies, including dermabrasion and a combination of intralesional therapies, are effective in managing keloids in PDP patients. This case contributes to the understanding of managing rare diseases and underscores the importance of personalized approaches to improve therapeutic outcomes in patients with complete primary PDP and concurrent keloids.

Impact of anesthesia on postoperative breast cancer prognosis: A narrative review.

The incidence of breast cancer has exhibited an annually increasing trend, and the disease has become the most common malignant tumour worldwide. Currently, the primary treatment for breast cancer is surgical resection. However, metastatic recurrence is the main cause of cancer-related death in this patient population. Various factors are associated with breast cancer prognosis, and anaesthesia-induced changes in the tumour microenvironment have attracted increasing attention. To date, however, it remains unclear whether anaesthetic drugs have a positive or negative impact on cancer outcomes after surgery. The present article reviews the effects of different anaesthetics on the postoperative prognosis of breast cancer surgery to guide the choice of anaesthetic technique(s) and agents for such patients.

Biphasic co-detection of melanoma aneuploid tumor cells and tumor endothelial cells in guidance of specifying the field cancerized surgical excision margin and administering immunotherapy.

An optimum safety excision margin (EM) delineated by precise demarcation of field cancerization along with reliable biomarkers that enable predicting and timely evaluating patients' response to immunotherapy significantly impact effective management of melanoma. In this study, optimized biphasic "immunofluorescence staining integrated with fluorescence insitu hybridization" (iFISH) was conducted along the diagnosis-metastasis-treatment-cellular MRD axis to longitudinally co-detect a full spectrum of intact CD31- aneuploid tumor cells (TCs), CD31+ aneuploid tumor endothelial cells (TECs), viable and necrotic circulating TCs (CTCs) and circulating TECs (CTECs) expressing PD-L1, Ki67, p16 and Vimentin in unsliced specimens of the resected primary tumor, EM, dissected sentinel lymph nodes (SLNs) and peripheral blood in an early-stage melanoma patient. Numerous PD-L1+ aneuploid TCs and TECs were detected at the conventional safety EM (2 cm), quantitatively indicating the existence of a field cancerized EM for the first time. Contrary to highly heterogeneous PD-L1 expression and degrees of Chr8 aneuploidy in TCs and TECs in the primary lesions as well as CTCs and CTECs in peripheral blood, almost all TCs and TECs in SLNs and EM were homogeneously PD-L1+ haploid cells. Dynamic monitoring and cellular MRD assessment revealed that, in contrast to PD-L1+ CTCs being responsive to the immune checkpoint inhibitor (ICI-anti-PD-1), multiploid (≥pentasomy 8) PD-L1+ and Ki67+ CTECs were respectively resistant to ICI-sensitized T cells. In therapeutically stressed lymphatic and hematogenous metastatic cascades, stratified phenotypic and karyotypic profiling of iFISH tissue and liquid biopsied TCs, TECs, CTCs and CTECs in future large-cohort studies will enable appropriate re-specification of the optimal safety EM and distribution mapping of in-depth characterized, subcategorized target cells to help illustrate their metastatic relevance, ultimately improving risk stratification and clinical intervention of tumor progression, metastases, therapy resistance and cancer relapse.

Association of Controlling Nutritional Status Score With Adverse Outcomes in Patients With Coronary Artery Disease: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis sought to examine the association between the controlling nutritional status (CONUT) score and adverse outcomes in patients with coronary artery disease (CAD). PubMed and Embase databases were searched for eligible studies from their inceptions to December 12, 2021 to identify studies investigating the association of the CONUT score with major adverse cardiovascular events (MACEs) and all-cause mortality in CAD patients. Twelve studies (36,198 CAD) patients satisfied the criteria. Comparison of the high with low CONUT score, the pooled multivariate adjusted risk ratios (RR) was 1.78 (95% confidence intervals [CI] 1.36-2.32) for MACEs and 1.45 (95% CI 1.27-1.66) for all-cause mortality, respectively. When compared with patients with normal nutrition, malnourished (defined by the CONUT score ≥2) patients conferred a 52% increased risk of MACEs. Additionally, per point CONUT score increment was associated with 15% and 11% higher risk of MACEs and all-cause mortality, respectively. Higher CONUT score independently predicts the MACEs all-cause mortality in CAD patients. Estimation of nutritional status using the CONUT score could be helpful for improving risk classification of CAD.

The utility of high-frequency 18 MHz ultrasonography for preoperative evaluation of acral melanoma thickness in Chinese patients.

Background: Despite the increasing use of preoperative ultrasound evaluation for melanoma, there is limited research on the use of this technique for Acral Melanoma (AM). Methods: This retrospective study analyzed the electronic medical records of patients who underwent preoperative evaluation for cutaneous melanoma maximum thickness using an 18 MHz probe and histopathological examination between December 2017 and March 2021 at the Department of Dermatology in Xiangya Hospital, Central South University. Results: A total of 105 patients were included in the study. The mean tumor thickness was 3.9 mm (s.d., 2.3), with 63% of the specimens showing ulceration and 44 patients showing lymph node metastasis. The results showed a good correlation between the high-frequency ultrasonography (HFUS) and histopathological thickness measurements, with a Spearman's correlation coefficient of 0.83 [(95% CI 0.73-0.90) (P < 0.001)]. The positive predictive value (PPV) of sonography in identifying tumor thickness was also found to be high. Conclusion: Our study suggests that high-frequency 18 MHz ultrasonography is an effective tool for the preoperative evaluation of AM thickness. The HFUS measurements correlated well with the histopathological thickness measurements, making it a valuable and reliable method for clinicians to assess the thickness of melanoma lesions preoperatively.
