Review
Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), grouped together under the terminology of epidermal necrolysis (EN), are a spectrum of life-threatening dermatologic conditions. A lack of standardization and validation for existing endpoints has been identified as a key barrier to the comparison of these therapies and development of evidenced-based treatment. Following PRISMA guidelines, we conducted a systematic review of prospective studies involving systemic or topical treatments for EN, including dressing and ocular treatments. Outcomes were separated into mortality assessment, cutaneous outcomes, non-cutaneous clinical outcomes, and mucosal outcomes. The COSMIN Risk of Bias tool was used to assess the quality of studies on reliability and measurement error of outcome measurement instruments. Outcomes across studies assessing treatment in the acute phase of EN were varied. Most data came from prospective case reports and cohort studies representing the lack of available randomized clinical trial data available in EN. Our search did not reveal any EN-specific validated measures or scoring tools used to assess disease progression and outcomes. Less than half of included studies were considered "adequate" for COSMIN risk of bias in reliability and measurement error of outcome measurement instruments. With little consensus about management and treatment of EN, consistency and validation of measured outcomes is of the upmost importance for future studies to compare outcomes across treatments and identify the most effective means of combating the disease with the highest mortality managed by dermatologists.

Review
BACKGROUND
For patients looking for temporary results or who do not want surgery, nonsurgical rhinoplasty using filler injections has become increasingly popular. Filler materials and surgical techniques have improved in recent years, but serious complications remain. Therefore, the aim of this systematic review is to summarize the common types of fillers and injection techniques, complications, and treatment to help clinicians perform in a safer and more effective way.
METHODS
A systematic review was performed using keywords and Medical Subject Headings search terms. PubMed, Embase, and the Cochrane Library were searched using the appropriate search terms. Data collected from each study included injection materials, location, technique, patient satisfaction and complications, and treatment.
RESULTS
From the 1812 studies identified, 30 were included in the systematic review. A total of 9657 patients underwent nonsurgical rhinoplasty, most commonly with hyaluronic acid (HA) (96.76%), followed by calcium hydroxyapatite (CaHA) (1.22%). Overall satisfaction was 99.08%. The overall incidence of complications was 39.11%, with the highest incidence of erythema and swelling (27.95%). Most of the complications are mild, but there are still 0.27% of the patients who have undergone severe complication-an arterial occlusion.
CONCLUSIONS
Nonsurgical rhinoplasty is an effective and relatively safe option for improving the profile of the nose, with a short operative time and high patient satisfaction. Most of the complications were mild, but still serious vascular complications such as blindness, skin necrosis, and stroke were as high as 0.27%. A thorough understanding of the anatomy of the nasal vessels and a precise surgical technique is an important basis for prevention. A BULLET POINT LIST: (1) We summarize the common types of fillers and injection techniques, complications, and treatment of complications to guide physicians to perform nonsurgical rhinoplasty in a safer and more effective manner. (2) Out of 1812 studies through the search strategy, 30 articles were included in the systematic review. A total of 9657 patients underwent nonsurgical rhinoplasty. (3) Nonsurgical rhinoplasty is an effective and relatively safe option to improve the profile of the nose, with a short surgical time and high patient satisfaction. (4) Most of the complications were mild, but some severe complications due to the vascular factors such as blindness, skin necrosis, and cerebral infarction need to be vigilant.

Review
BACKGROUND AND OBJECTIVE
A 6-month interval between systemic isotretinoin (ISO) and the initiation of energy-based interventions has been recommended, due to concerns about keloid formation and delayed wound healing. While this postponement goes against the current trend of early intervention for acne scarring. This systematic review evaluates the efficacy, safety, and patient satisfaction of combinations of ISO with energy-based devices (EBD).
STUDY DESIGN/METHODS AND MATERIALS
PubMed, Embase, Web of Science, Cochrane Library, and Cochrane Central Register of Controlled Trials were comprehensively searched up to April 2023 according to PRISMA guidelines. Two independent reviewers screened the titles and abstracts to select articles. The quality of the literature was assessed for each study design.
RESULTS
A total of 16 studies addressing the efficacy and safety of energy-based modalities combined with ISO were identified, including six randomized controlled trials (RCTs), two case series, seven cohort studies, and one case report. ISO combinations with intense pulsed light (IPL), fractional ablative CO laser, pulsed dye laser (PDL), non-ablative fractional laser (NAFL) and fractional microneedle radiofrequency (FMRF) have been tested for improving acne severity, acne scarring and erythema.
CONCLUSION
The current evidence does not justify delaying the use of EBDs for patients who have recently undergone or are currently receiving ISO treatment. Evidence-based treatments such as PDL, NAFL, and FMRF etc. are suggested relatively safe and effective in treating acne and acne scarring.

Pityriasis rubra pilaris (PRP) is a rare and chronic inflammatory dermatologic condition characterized by hyperkeratotic salmon-colored plaques and palmoplantar keratoderma. Traditional therapeutic modalities have shown limited efficacy and often entail potential adverse effects, highlighting the need for alternative treatment options. Our review aims to summarize the current evidence on the off-label use of IL-23 inhibitors, risankizumab and guselkumab, in the treatment of PRP. These biologic agents have been approved for psoriasis, and their potential role in managing PRP has recently garnered interest. We conducted a comprehensive literature search on PubMed and Scopus databases, identifying relevant studies published in English up to June 2023 following PRISMA guidelines. A total of 10 studies were selected for data extraction and review. Results from the selected studies demonstrated encouraging outcomes with both risankizumab and guselkumab in managing PRP. Among 11 patients treated with risankizumab, 10 showed notable improvements in various disease manifestations, including pruritus, erythema, and affected body surface area. DLQI scores and BSA percentages reported a significant improvement before and after risankizumab treatment (p = 0.0322; p = 0.0216). However, two cases also reported symptom aggravation or even disease worsening. Patients treated with guselkumab exhibited ultimate improvement in all five cases, with complete clearance in three out of five cases. DLQI and BSA percentages also reported significant improvement with treatment with guselkumab (p = 0.0172; p < 0.0001). While most cases demonstrated positive outcomes, there were isolated instances of worsening symptoms, emphasizing the need for caution and further investigation. Further research with larger sample sizes and longer follow-up periods is necessary to establish the efficacy, optimal dosing, and long-term safety of risankizumab and guselkumab in treating PRP. Overall, we provide valuable insights into the potential use of IL-23 inhibitors, risankizumab, and guselkumab, as promising treatment options for PRP. These biologics have shown efficacy in improving symptoms in treatment-resistant cases, offering new avenues for clinicians to explore in the treatment of PRP.

Review
Stevens Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions characterised by keratinocyte apoptosis, necroptosis and epidermal detachment. Several cytokines and cytotoxic proteins have been shown to be elevated in the blood and skin of SJS/TEN sufferers and biologics such as intravenous immune globulin and tumour necrosis factor (TNF)-alpha inhibitors have demonstrated good therapeutic potential. The exact pathogenic model of SJS/TEN however remains elusive. This systematic review aimed to evaluate the case-control studies of cytokines and cytotoxic proteins in the blister fluid and skin of adults with Stevens Johnson syndrome and/or toxic epidermal necrolysis. This review was registered with INPLASY and conducted in accordance with the PRISMA reporting guidelines. Potential bias was assessed using the NIH criteria. Eleven articles describing results from 96 cases and 170 controls were included. Fas, Fas ligand, Interleukin (IL)-8 and B-cell lymphoma (Bcl)-2 were elevated in SJS/TEN blister fluid and skin tissue, compared with healthy controls. IL-2, IL-6, TNF-alpha, tumour necrosis factor-related apoptosis-inducing ligand (TRAIL), interferon-gamma and matrix metalloproteinase-2 were elevated in SJS/TEN blister fluid compared with fluid sampled from lesional controls. Granulysin, IL-33, TGF-beta-1 and IL-13 were elevated in SJS/TEN skin tissue compared with lesional lichen planus tissue, as was IL-13, IFN-gamma, IL-2 and IL-5, when compared with erythema multiforme tissue. A wide array of cytokines and cytotoxic proteins are present at higher concentrations in the blister fluid and skin tissue of SJS/TEN patients compared with healthy and lesional controls. Our findings suggest that these proteins may be pathogenic, as well as possibly markers for diagnosis, disease severity and course. They may also prove to be useful therapeutic targets. More research is needed.

Review
Keloids are benign, fibroproliferative dermal tumours, often arising after trauma, that are more common in darker skin types. Numerous therapeutic options have been employed for the treatment of keloids; however, there is no one gold standard approach. Five-fluorouracil, a potent chemotherapeutic agent, has emerged as a promising therapeutic option. Therefore, this systematic review, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, focused on providing a broad overview of the use of 5-fluorouracil for the management of keloids. Forty studies (2325 patients) met inclusion criteria and investigated 5-fluorouracil for keloid management, with 19 studies (1043 patients) including a 5-fluorouracil monotherapy group. Five-fluorouracil monotherapy demonstrated consistent keloid improvement with >254 keloids injected across various anatomical regions. Five-fluorouracil monotherapy was most often compared to intralesional triamcinolone acetonide, utilizing the Patient and Observer Scar Assessment Scale and the Vancouver Scar Scale. The most common keloid parameters assessed were height, size, volume, width, length, induration, pruritus, and erythema. Five-fluorouracil monotherapy exhibited substantial improvements, with weight averages of 73% of patients experiencing >25% improvement and 67% achieving >50% improvement. Relapse rate was 16% at 27 weeks after 5-fluorouracil monotherapy treatment. Limitations included potential selection bias, language restrictions, and heterogenous data analysis among studies. Overall, our findings underscore the potential effectiveness of 5-fluorouracil monotherapy in the management of keloids, with an encouraging safety profile. Larger prospective trials are needed to determine optimal therapy or combination therapy for the management of keloids. This detailed compilation of treatment protocols, outcomes, and relapse rates stand as a valuable resource for further research and clinical applications.

Review
Serpentine supravenous hyperpigmentation (SSH) describes increased skin pigmentation that develops in the area immediately overlying the vessels through which chemotherapeutic drugs are administered. While SSH can be cosmetically distressing and there are no definitive management options, the literature is severely limited and the variations in clinical presentation, risk factors, and histopathology of SSH across patients are not well understood. We aimed to systematically summarize characteristics from current available data, and thus improve SSH awareness and management. A literature search was conducted in PubMed using specific eligibility criteria through the end of December 2022. Included articles focused on patients who experienced SSH after chemotherapy infusion. Study quality was assessed using a modified Oxford Centre for Evidence-Based Medicine quality rating scheme. Of the 41 articles identified by literature search, 24 met eligibility criteria. Two additional articles were identified through the reference sections of retrieved articles, for 26 articles total. All articles were case reports, representing 28 patients total. Locations of SSH were mostly in the forearm near the site of injection (85%), and the most common associated symptom was erythema. Histopathologic analysis was available for half of cases, the majority of which were inflammatory in nature. The most common inflammatory pattern observed was a vacuolar/lichenoid interface dermatitis. Duration of SSH ranged from days to > 1 year after the chemotherapy was stopped. Six (21%) patients were managed with topical steroids and oral vasodilators, six (21%) patients switched to central venous infusion rather than peripheral infusion, five (18%) patients received only supportive care, three (11%) patients received venous washing with chemotherapy, three (11%) patients stopped chemotherapy, and one (4%) patient reduced the chemotherapy dosage. Ten (36%) patients attained complete resolution, seven (25%) had SSH that was near resolution/fading, and three (11%) had persistent hyperpigmentation. Although SSH often spontaneously resolves once the chemotherapeutic agent is stopped, it can persist in some patients and cause significant distress. As the literature is severely limited and there are no definitive treatments, additional research using more standardized definitions and methods of assessments is necessary to improve characterization of SSH and evaluate potential interventions.

Meta-Analysis Review
OBJECTIVES
Hidradenitis suppurativa (HS) is a chronic inflammatory condition characterized by painful nodules, draining tunnels, and fibrotic scarring in intertriginous, hair-bearing areas. The pathogenesis involves follicular occlusion and subsequent rupture, leading to uncontrolled inflammation. Treatment options for HS are limited and lack universal effectiveness. Laser hair removal (LHR) has been explored as a potential treatment; however, the efficacy and appropriate laser modalities remain unclear. This systematic review examined the efficacy and adverse effects of LHR in HS.
METHODS
A comprehensive literature search was conducted from inception to September 2023 in Ovid MEDLINE, Ovid Embase, and The Cochrane Library (Wiley) with predefined inclusion and exclusion criteria, and a meta-analysis was conducted.
RESULTS
Ten studies were selected (n = 227 total patients) and included six randomized controlled trials, two nonrandomized experimental studies, and two case series. Various laser modalities, including long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) (n = 115), intense pulsed light (n = 18), Alexandrite (n = 54), intralesional 1064 nm diode (n = 20), and combined fractional CO and long-pulsed Nd:YAG laser (n = 20), consistently demonstrated significant improvement in HS disease severity, irrespective of the disease scoring method used. Minimal adverse effects (primarily mild pain and erythema) were reported. A meta-analysis of three studies utilizing long-pulsed Nd:YAG laser demonstrated a standardized mean difference in disease severity of -1.68 (95% confidence interval: -2.99; -0.37), favoring treatment with LHR for HS.
CONCLUSIONS
Hair follicles are key in HS pathogenesis and all included studies showed a significant improvement in HS disease severity after LHR regardless of the laser device used, likely related to hair follicle unit destruction. HS is a complex and heterogenous condition, and multiple disease scoring methods complicate outcome comparisons across studies. However, LHR, utilizing various techniques, is an effective treatment option for HS with minimal adverse effects.

Review
BACKGROUND
Laser therapy has emerged as a promising treatment modality for improving the appearance and symptoms associated with hypertrophic and keloid scars. In this network meta-analysis, we aimed to evaluate the efficacy of different laser types in treating hypertrophic and keloid scars.
METHODS
A comprehensive search of four databases was conducted to identify relevant studies published up until July 2023. Data were extracted from eligible studies and pooled as mean difference (MD) for continuous outcomes and risk ratio (RR) for dichotomous data in a network meta-analysis (NMA) model, using R software.
RESULTS
A total of 18 studies, comprising 550 patients, were included in the analysis. Pooling our data showed that fractional carbon dioxide (FCO2) plus 5-fluorouracil (5-FU) was superior to control in terms of Vancouver Scar Scale (VSS), pliability score, and thickness; [MD = - 5.97; 95% CI (- 7.30; - 4.65)], [MD = - 2.68; 95% CI (- 4.03; - 1.33)], [MD = - 2.22; 95% CI (- 3.13; - 1.31)], respectively. However, insignificant difference was observed among FCO2 plus 5-FU compared to control group in terms of erythema, vascularity, redness and perfusion, and pigmentation [MD = - 0.71; 95% CI (- 2.72; 1.30)], [MD = - 0.44; 95% CI (- 1.26; 0.38)], respectively.
CONCLUSION
Our NMA found that the FCO2 plus 5-FU was the most effective intervention in decreasing the VSS and thickness, while FCO2 plus CO2 was the most effective intervention in decreasing the pliability score. Further research is needed to determine the optimal laser parameters and long-term efficacy of laser therapy in hypertrophic and keloid scars.

BACKGROUND AND AIM
Extraintestinal manifestations (EIMs) pose a significant threat in inflammatory bowel disease (IBD) patients. Vedolizumab (VDZ) primarily affects the gastrointestinal tract. However, its impact on EIMs remains uncertain. Therefore, we conducted this meta-analysis to examine the effects of VDZ on EIMs during treatment.
METHODS
Relevant studies were identified by conducting thorough searches across electronic databases, including PubMed, Ovid Embase, Medline, and Cochrane CENTRAL. Primary outcomes focused on the proportion of patients with resolution for pre-existing EIMs in IBD patients receiving VDZ. Secondary outcomes included the proportion of patients with EIM exacerbations and new onset EIMs during VDZ treatment.
RESULTS
Our meta-analysis encompassed 21 studies. The proportion of patients with resolution of pre-existing EIMs in VDZ-treated IBD patients was 39% (150/386; 95% confidence interval [CI] 0.31-0.48). The proportion of patients with EIM exacerbations occurred at a rate of 28% (113/376; 95% CI 0.05-0.50), while new onset EIMs had a rate of 15% (397/2541; 95% CI 0.10-0.20). Subgroup analysis revealed a 40% (136/337) proportion of patients with resolution for articular-related EIMs and a 50% (9/18) rate for erythema nodosum. Exacerbation rates for arthritis/arthralgia, erythema nodosum/pyoderma gangrenosum, and aphthous stomatitis during VDZ use were 28% (102/328), 18% (7/38), and 11% (3/28), respectively. The incidence rate of newly developed EIMs during treatment was 11% (564/4839) for articular-related EIMs, with other EIMs below 2%.
CONCLUSION
VDZ demonstrates efficacy in skin-related EIMs like erythema nodosum and joint-related EIMs including arthritis, arthralgia, spondyloarthritis, and peripheral joint diseases. Some joint and skin-related EIMs may experience exacerbation during VDZ therapy.
