How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

Non-ablative fractionated laser skin resurfacing for the treatment of aged neck skin

Abstract Background: Aging of the neck skin includes poikiloderma of Civatte, skin laxity and wrinkles. While the vascular alterations of poikiloderma of Civatte can be effectively treated with lasers or intense pulsed light, a successful treatment of dyschromia, skin laxity and wrinkles is still difficult to achieve. Objective: To evaluate the safety and efficacy of non-ablative fractional 1540 erbium glass laser for the treatment of aged neck skin, also by means of in vivo reflectance confocal microscopy (RCM). Methods: A prospective study for neck resurfacing in 18 women with aged neck skin. Six laser treatments were performed in 4-week intervals with a 1540-nm erbium-glass fiber laser. Results: By using a 6-point grading scale, the mean score (±SD; range) at baseline was 3.6 (±1.5; 1-6) for skin dyschromia, 2.9 (±1.4; 1-6) for laxity and 3.3 (±1.3; 1-5) for wrinkles. Three months after the last laser session, we found a significant clinical improvement of dyschromia (p = 0.0002; Wilcoxon test), and wrinkles (p = 0.0004; Wilcoxon test), with a mean (±SD) reduction of 2.5 (±1.0) and 1.9 (±1.1) points in the 6-point grading scale, respectively. No change was observed in laxity. These results were also supported by structural changes documented by RCM. Conclusion: Non-ablative fractional 1540 erbium glass laser was both safe and effective for the treatment of dyschromia and wrinkles, but not effective for the laxity of the neck skin

Photodynamic therapy for actinic keratosis in vegan and omnivore patients: the role of diet on skin healing

Background: Photodynamic therapy (PDT) is an approved and effective treatment for actinic keratosis (AK). The time of complete skin healing is estimated to range between 5 and 10 days, but the role of nutrition in influencing it has never been evaluated. Objective: The aim of this study was to compare the time of skin healing and side effects in omnivores and vegans treated with PDT for AK. Materials and methods: Thirty omnivore and thirty vegan patients, treated with PDT for AK, were enrolled. Side effects, according to local skin response (LSR) score, were compared after 3, 7, and 30 days; the time of complete skin healing was recorded. Results: At day 3, day 7, and day 30 post treatment, vegan group showed higher total LSR score (p = .008, p < .001, p < .001, respectively), highlighting higher edema and vesiculation at day 3 (p < .001, p = .002, respectively), erythema, desquamation, edema, and vesiculation at day 7 (p < .001, p < .001, p < .001, p < .001, respectively) and erythema and desquamation after 30 days (p < .001, p < .001, respectively). The difference of complete skin healing was statistically significant (p < .001). Conclusions: The present study suggests that diet may have a prognostic and predictive role on PDT outcomes in term of side effects and time of skin repair

Combination of fractional erbium-glass laser and topical therapy in melasma resistant to triple-combination cream

Melasma is a common melanosis often difficult to treat

Melasma and low-energy Q-switched laser: Treatment assessment by means of in vivo confocal microscopy

Melasma is an acquired disorder of pigmentation for which several therapeutical options are currently available. Among them, low-energy Q-switched Nd:YAG laser (1,064 nm) has been successfully applied in case series although its long-term efficacy has yet to be proven. In vivo confocal microscopy is a novel imaging technique that permits to explore the skin tissue at a nearly histologic resolution. The aim of our study was to evaluate the laser treatment efficacy by means of confocal microscopy at different time points to elucidate the mechanism of action of the laser and its possible drawbacks. Eight women who presented with melasma on the face were subjected to low-energy Q-switched Nd:YAG laser treatment and then analyzed by means of confocal microscopy. An overall improvement of melasma was noticed clinically and microscopically by means of confocal microscopy. Four cases revealed the presence of dendritic-shaped cells upon confocal microscopy and those patients were the ones presenting with a relapse of the disease. The interpretation of these cells is that they could represent reasonably activated melanocytes. This opens the question whether laser treatment should be modulated to avoid side-effects associated with its use. Confocal microscopy has emerged as an excellent tool for a better understanding of the changes occurring during laser treatment

Nonablative fractional photothermolysis for acne scars: clinical and in vivo microscopic documentation of treatment efficacy

Fractional photothermolysis has been shown to improve various types of scarring, including atrophic acne scars. The aim of the present authors was to assess the efficacy and safety of the nonablative fractional photothermolysis in the treatment of moderate and severe acne scars. Eighty-seven patients with moderate or severe acne scarring were treated with six sessions with a 1540-nm Erbium glass fiber laser at 3-week intervals. Six months after the final session, 7/87 (8%) patients showed a moderate improvement, whereas 80/87 (92%) patients had a marked improvement. In a subset of patients, the present authors also applied in vivo reflectance confocal microscopy to highlight the relevant microscopic changes. Hence, early and late posttreatment findings, most importantly the replacement of a coarser collagen with a new one, similar to the collagen seen in healthy skin, were observed. In accordance to previous studies, the present authors conclude that nonablative fractional photothermolysis is a safe and effective treatment for moderate or severe acne scarring

Biophysical and Biological Tools to Better Characterize the Stability, Safety and Efficacy of a Cosmeceutical for Acne-Prone Skin

(1) Background: Acne is a widespread skin disease, especially among adolescents. Following the COVID-19 pandemic and the use of masks, the problem has been affecting a greater number of people, and the attention of the skin care beauty routine cosmetics has been focused on the &ldquo;Maskne&rdquo;, caused by the sebum excretion rate (SER) that stimulates microbial proliferation. (2) Methods: the present study was focused on the rheological characterization and quality assurance of the preservative system of an anti-acne serum. The biological effectiveness (cytotoxicity&mdash;skin and eye irritation&mdash;antimicrobial, biofilm eradication and anti-inflammatory activity) was evaluated in a monolayer cell line of keratinocytes (HaCaT) and on 3D models (reconstructed human epidermis, RHE and human reconstructed corneal epithelium, HCE). The Cutibacterium acnes, as the most relevant acne-inducing bacterium, is chosen as a pro-inflammatory stimulus and to evaluate the antimicrobial activity of the serum. (3) Results and Conclusions: Rheology allows to simulate serum behavior at rest, extrusion and application, so the serum could be defined as having a solid-like behavior and being pseudoplastic. The preservative system is in compliance with the criteria of the reference standard. Biological effectiveness evaluation shows non-cytotoxic and irritant behavior with a good antimicrobial and anti-inflammatory activity of the formulation, supporting the effectiveness of the serum for acne-prone skin treatment

A Practical Approach for the In Vitro Safety and Efficacy Assessment of an Anti-Ageing Cosmetic Cream Enriched with Functional Compounds

(1) Background: Cosmeceuticals are topical products applied to human skin to prevent skin ageing and maintain a healthy skin appearance. Their effectiveness is closely linked to the compounds present in a final formulation. In this article, we propose a panel of in vitro tests to support the efficacy assessment of an anti-ageing cream enriched with functional compounds. (2) Methods: biocompatibility and the irritant effect were evaluated on reconstructed human epidermis (RHE) and corneal epithelium (HCE) 3D models. After a preliminary MTT assay, normal human dermal fibroblasts (NHDF) and keratinocytes (HaCaT) were used to evaluate the extracellular matrix (ECM) protein synthesis, and interleukin-6 (IL-6) and metalloproteinase-1 (MMP-1) production. (3) Results: data collected showed good biocompatibility and demonstrated the absence of the irritant effect in both 3D models. Therefore, we demonstrated a statistical increase in collagen and elastin productions in NHDF cells. In HaCaT cells, we highlighted an anti-inflammatory effect through a reduction in IL-6 levels in inflammatory stimulated conditions. Moreover, the reduction of MMP-1 production after UV-B radiation was demonstrated, showing significant photo-protection. (4) Conclusion: a multiple in vitro assays approach is proposed for the valid and practical assessment of the anti-ageing protection, anti-inflammatory and biocompatible claims that can be assigned to a cosmetic product containing functional compounds
