BACKGROUND
Cutaneous vulval Crohn disease (VCD) is an under-recognised extra-intestinal manifestation of Crohn disease (CD) which is challenging to identify and treat. It causes significant oedema, painful deep fissures, and has potential to cause permanent disfiguring changes to vulval anatomy. There is no agreement on the best management for VCD.
OBJECTIVES
This systematic review evaluates the use of metronidazole for the treatment of VCD in women and children.
METHODS
We conducted a systematic review (PROSPERO CRD42021285033) of the use of metronidazole in clinically or histologically diagnosed non-contiguous VCD in patients of all ages and ethnicities. We recorded clinical improvement, reduction in flares, relapse and adverse events using a standardised form.
RESULTS
49 records (40 case reports and 9 case series) met inclusion criteria, comprising a total of 57 patients with an age range of 5-61 years. The most reported presenting features in VCD were: oedema, erythema, ulcers/fissures and induration/thickening. Gastrointestinal CD was present in 33/57 (58%). Vulval biopsies were undertaken in 47/57 (83%). Daily doses ranged from 250 to 1500 mg with treatment duration 8 days to 18 months. Improvement of any magnitude was observed in 40/57 (70%) cases. Relapse was described in 11/57 (19%) cases. No response/worsening was reported in 17/57 (30%) cases. Adverse events occurred in two patients.
CONCLUSION
Metronidazole appears to be useful in managing VCD, either as a primary treatment or adjunctive therapy. However, the evidence is insufficient for firm conclusions to be drawn. Further studies including randomised controlled trials are recommended.

Review
Hidradenitis suppurativa is a chronic inflammatory skin condition that affects the hair follicles in areas of the body with apocrine glands. The condition is characterized by recurrent, painful nodules, abscesses, and draining sinuses that can lead to scarring and disfigurement. In this present study, we provide a focused evaluation of recent developments in hidradenitis suppurativa research, including novel therapeutics and promising biomarkers that may facilitate clinical diagnosis and treatment. We conducted a systematic review of controlled trials, randomized controlled trials, meta-analyses, case reports, and Cochrane Review articles in accordance with the PRISMA guidelines. The Cochrane Library, PubMed, EMBASE, and Epistemonikos databases were queried via Title/Abstract screen. Eligibility criteria included the following: (1) has a primary focus on hidradenitis suppurativa, (2) includes measurable outcomes data with robust comparators, (3) details the sample population, (4) English language, and (5) archived as full-text journal articles. A total of 42 eligible articles were selected for review. Qualitative evaluation identified numerous developments in our understanding of the disease's multiple potential etiologies, pathophysiology, and treatment options. It is important for individuals with hidradenitis suppurativa to work closely with a healthcare provider to develop a comprehensive treatment plan that addresses their individual needs and goals. To meet this objective, providers must keep current with developments in the genetic, immunological, microbiological, and environmental factors contributing to the disease's development and progression.

Review
BACKGROUND
Keloid scarring is one of the most common types of pathological scarring. Keloid scars that fail to heal can affect a person's physical and psychological function by causing pain, pruritus, contractures, and cosmetic disfigurement. Silicone gel sheeting (SGS) is made from medical-grade silicone reinforced with a silicone membrane backing and is one of the most commonly used treatments for keloid scars. However, there is no up-to-date systematic review assessing the effectiveness of SGS for keloid scars. A clear and rigorous review of current evidence is required to guide clinicians, healthcare managers and people with keloid scarring.
OBJECTIVES
To assess the effectiveness of silicone gel sheeting for the treatment of keloid scars compared with standard care or other therapies.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was December 2021.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that recruited people with any keloid scars and assessed the effectiveness of SGS.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, risk of bias assessment, data extraction and GRADE assessment of the certainty of evidence. We resolved initial disagreements by discussion, or by consulting a third review author when necessary.
MAIN RESULTS
Two studies met the inclusion criteria. Study sample sizes were 16 and 20 participants. The trials were clinically heterogeneous with differences in causes for scarring (e.g. surgery, infected wounds, and trauma), site (e.g. chest and back), and ages of scars. The duration of follow-up was three and four and a half months. The included studies reported three comparisons; SGS compared with no treatment, SGS compared with non-silicone gel sheeting (a dressing similar to SGS but which does not contain silicone), and SGS compared with intralesional injections of triamcinolone acetonide. One trial had a split-body design and one trial had an unclear design (resulting in a mix of paired and clustered data). The included studies reported limited outcome data for the primary review outcome of scar severity measured by health professionals and no data were reported for severity of scar measured by patients or adverse events. For secondary outcomes some data on pain were reported, but health-related quality of life and cost-effectiveness were not reported. Both trials had suboptimal outcome reporting, thus many domains in the risk of bias were assessed as unclear. All evidence was rated as being very low-certainty, mainly due to risk of bias, indirectness, and imprecision. SGS compared with no treatment Two studies with 33 participants (76 scars) reported the severity of scar assessed by health professionals, and we are uncertain about the effect of SGS on scar severity compared with no treatment (very low-certainty evidence, downgraded once for risk of bias, once for inconsistency, once for indirectness, and once for imprecision). We are uncertain about the effect of SGS on pain compared with no treatment (21 participants with 40 scars; very low-certainty evidence, downgraded once for risk of bias, once for inconsistency, once for indirectness, and once for imprecision). No data were reported for other outcomes including scar severity assessed by patients, adverse events, adherence to treatment, health-related quality of life and cost-effectiveness. SGS compared with non-SGS One study with 16 participants (25 scars) was included in this comparison. We are uncertain about the effect of SGS on scar severity assessed by health professionals compared with non-SGS (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and once for imprecision). We are also uncertain about the effect of SGS on pain compared with non-SGS (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and once for imprecision). No data were reported for other outcomes including scar severity assessed by patients, adverse events, adherence to treatment, health-related quality of life and cost-effectiveness. SGS compared with intralesional injections of triamcinolone acetonide One study with 17 participants (51 scars) reported scar severity assessed by health professionals, and we are uncertain about the effect of SGS on scar severity compared with intralesional injections of triamcinolone acetonide (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and once for imprecision). This study also reported pain assessed by health professionals among 5 participants (15 scars) and we are uncertain about the effect of SGS on pain compared with intralesional injections of triamcinolone acetonide (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and twice for imprecision). No data were reported for other outcomes including scar severity assessed by patients, adverse events, adherence to treatment, health-related quality of life and cost-effectiveness.
AUTHORS' CONCLUSIONS
There is currently a lack of RCT evidence about the clinical effectiveness of SGS in the treatment of keloid scars. From the two studies identified, there is insufficient evidence to demonstrate whether the use of SGS compared with no treatment, non-SGS, or intralesional injections of triamcinolone acetonide makes any difference in the treatment of keloid scars. Evidence from the included studies is of very low certainty, mainly driven by the risk of bias, indirectness, and imprecision due to small sample size. Further well-designed studies that have good reporting methodologies and address important clinical, quality of life and economic outcomes are required to reduce uncertainty around decision-making in the use of SGS to treat keloid scars.

Review
Infantile hemangioma (IH) is the most common vascular tumor in infancy. Although IHs can regress spontaneously, some problematic IHs still need treatment. However, either treated or untreated IHs may leave skin sequelae which can cause permanent disfigurement. Many studies evaluated the short-term efficacy of different kinds of treatment, but now, few studies are focusing on long-term skin sequelae. The objectives of our systemic review were to identify skin sequelae of IH thoroughly, determine specific factors associated with long-term IH sequelae, and learn how to improve these sequelae. We searched the following electronic databases: PubMed, EMBASE, Cochrane Library, and Clinicaltrials.gov. Three independent authors assessed the articles, and we reported this systemic review following PRISMA guidelines. Of 4448 articles initially identified, 62 underwent full-text review, and 17 met inclusion criteria. The overall rate of sequelae ranged from 5.3 to 93.5%. Factors associated with skin sequelae included patients' demographics, hemangioma characteristics, and treatment factors. What is Known: • Infantile hemangioma is the most common vascular tumor during infancy. • Infantile hemangiomas can regress spontaneously but either treated or untreated patients may leave permanent skin sequelae. What is New: • Skin sequelae in involuted Infantile hemangiomas are very common. • It is significant to prevent, recognize, and improve skin sequelae of infantile hemangiomas.

BACKGROUND
Autologous fat transfer (AFT) is a minimally invasive technique that employs a patient's own fat to correct disfiguring sequelae for breast reconstruction in postoperative breast cancer patients. However, the results of studies on this topic were controversial. In order to explore the effect of AFT on breast reconstruction after breast cancer surgery, we included cohort studies and conducted a meta-analysis.
METHODS
A literature search was conducted using PubMed, Embase, Cochrane Library, and Web of Science databases for relevant studies published up to September 14, 2020. We identified the eligible studies based on the PICOS principles, populations (patients diagnosed with breast cancer), interventions (patients undergoing AFT after breast cancer surgery), controls (patients who did not receive AFT after breast cancer surgery), outcomes [local recurrence (LR) rate, regional recurrence (RRR) rate, locoregional recurrence (LRR) rate, distant metastasis rate, systemic recurrence (SR) rate, and total death rate], study design (cohort studies). The I statistic was conducted to estimate heterogeneity. Relative risks (RRs) with 95% confidence intervals (CIs) were presented to evaluate whether AFT compromises oncological safety in breast reconstruction. Funnel plots and Egger's test were adopted to assess publication bias. Quality assessment for the included studies using the Newcastle-Ottawa Scale (NOS).
RESULTS
Twenty-two cohort studies involving 9,971 postoperative patients with breast cancer were identified, with 3,622 receiving AFT being the experimental group, and 6,349 not receiving AFT in the control group. The overall quality of the included studies was rated as high. No significant differences in the rate of LR (RR: 0.916, 95% CI: 0.704-1.192), RRR (RR: 1.175, 95% CI: 0.773-1.787), LRR (RR: 0.788, 95% CI: 0.617-1.006), distant metastasis (RR: 1.133, 95% CI: 0.906-1.417), and total deaths (RR: 0.753, 95% CI: 0.539-1.051) were observed between the experimental group and control group (P>0.05). However, the AFT group had a lower rate of SR (RR: 0.671, 95% CI: 0.491-0.915, P=0.012).
CONCLUSIONS
The AFT group did not increase the rate of LR, RRR, LRR, distant metastasis, and total deaths in postoperative patients, which may indicate that AFT can be performed safely in breast reconstruction after excision of breast tumor.

Vascularized composite allotransplantation of the face is an exceedingly complex procedure, requiring extensive planning and surgical precision in order to successfully manage patients with facial disfigurements. This review aims to present an overview of the salient anatomic considerations in facial transplantation, as well as give attention to unique patient populations and special considerations.A literature review was performed in search of articles pertaining to considerations in facial transplantation using the databases PubMed, Web of Science, and Cochrane. Articles selected for further review included full-text articles with an emphasis on specific anatomic defects and how they were addressed in the transplant process, as well as management of special patient populations undergoing facial transplantation. In total, 19 articles were deemed appropriate for inclusion.The use of computer-assisted technologies for the planning portion of the procedure, as well as intraoperative efficiency, has yielded favorable results and can be considered as part of the operative plan. The ultimate outcome is dependent upon the synchronization of subunits of the allograft and the desired functional outcomes, including osseous, ocular, oral, and otologic considerations. Management of specific pathology and subgroups of patients are critical aspects. Although pediatric face transplantation has not yet been performed, it is a likely a future step in the evolution of this procedure.When performing a face transplantation, many components must be considered pre-, intra-, and post-operatively. This systematic review presents specific anatomic considerations, as well as information about special patient populations within this crosssection of multidisciplinary microsurgery, psychiatry, and transplant immunology.

Infantile hemangiomas (IH) are the most common benign tumors of childhood. Timely diagnosis and management of higher-risk IH is key in avoiding permanent disfigurement, visual impairment, and life-threatening airway compromise. Here, we identify and critically appraise existing clinical practice guidelines (CPGs) for IH diagnosis and management. A systematic search of MEDLINE, SCOPUS, and EMBASE was conducted until August 2021. Four independent reviewers assessed each CPG utilizing the Appraisal of Guidelines for Research and Evaluation, 2 edition (AGREE II). An scaled domain score of ≥60% demonstrated adequacy in a given domain. Intraclass correlation coefficients (ICC) assessed agreement and scoring consistency between the reviewers. Eight CPGs were eligible and included for critical appraisal. Only one CPG was classified as 'high quality', with the remaining seven guidelines being 'average' ( = 3) or 'low' ( = 4) quality. Six guidelines (75.0%) were conducted via nonsystematic literature searches. The 'Applicability' (40.4%±14.0) and 'Rigor of development' (46.9%±17.3) domains achieved the lowest scores, while the highest average scores were in 'Scope and purpose' (76.7%±11.3) and 'Editorial independence' (90.8%±13.0). We found high consistency between the four independent reviewers, with 'very good' ( = 5) or 'good' ( = 1) interrater reliability in all six AGREE II domains. Based on the AGREE II instrument, there is only one available high-quality consensus statement on the diagnosis and management of IH. Low scores in 'Rigor of development' and 'Applicability' suggest notable weaknesses in the development process and reporting quality of existing IH CPGs. Future guidelines should be backed by systematic literature searches and focus on guideline clinical translation.

Review
Autoimmune bullous dermatoses (ABDs), such as pemphigus and bullous pemphigoid (BP), cause cutaneous lesions that are painful and disfiguring. These conditions affect a patient's ability to perform everyday tasks, and individual lesions can take years to heal. Multiple small studies have examined how these conditions affect a patient's lifestyle. We systematically reviewed the trials that have evaluated the mental health of patients with bullous dermatoses. Of the 13 studies assessed, 2 domains of interest were primarily evaluated: quality of life (QOL) and psychological state. Quality of life predominantly was analyzed using the Dermatology Life Quality Index (DLQI). To evaluate psychological state, the General Health Questionnaire (GHQ) primarily was utilized. This review informs providers and summarizes the various ways that ABDs affect mental health.

Meta-Analysis Review
Melasma is a highly prevalent and cosmetically disfiguring pigmented skin disease. The post-treatment results are often unsatisfactory. A large number of clinical trials have tried to prove the effectiveness of the combination therapy involving laser therapy, but the results have been indeterminate. This study aimed to evaluate the effectiveness of laser treatment for melasma via a systematic review and meta-analysis. We respectively searched 4 databases and clinicaltrials.gov as of June 8, 2021. Two researchers independently searched for literature and extracted data. Study outcomes were computed by weighted mean differences (WMD). All statistical analyses were performed by the Review Manager version 5.3, STATA version 14 software at 95% confidence interval. We obtained 22 eligible studies which involved a total of 694 patients. After the heterogeneity test and sensitivity analysis, we took a subgroup meta-analysis on the before and after treatment of different laser types. We found that most lasers and laser-based combinations were associated with reduced melasma area and severity index (MASI), such as low-fluence Q-switch 1,064-nm Nd: YAG laser (QSNYL) (WMD: - 2.76; 95% CI: - 3.53 to - 1.99), fractional ablative CO2 laser (WMD: - 9.36; 95% CI: - 12.51 to - 6.21), and fractional ablative 2940-nm Er: YAG laser (WMD: - 2,72; 95% CI: - 3.94 to - 1.49). Significant decrease was seen in neither MASI score of non-ablative 1550-nm fractional laser (WMD: - 1.29; 95% CI: - 2.80 to 0.21) and picosecond laser (WMD: - 0.58; 95% CI: - 1.43 to 0.27), nor melanin index (MI) of low-fluence QSNYL treatment (WMD: 10.17; 95% CI: - 4.11 to 24.46). When using laser to treat melasma, various adverse reactions may occur, most of which will resolve quickly without subsequent treatment, such as edema, erythema, scaling, and burning sensation after treatment. However, for patients with darker skin, there are risks of postinflammatory hyperpigmentation and hypopigmentation. The laser and laser-based combination treatment for melasma could significantly reduce the MASI score, which was showed by our systematic review and meta-analysis.

Review
BACKGROUND
Oral cavity and oropharyngeal cancers are the most common cancers arising in the head and neck. Treatment of oral cavity cancer is generally surgery followed by radiotherapy, whereas oropharyngeal cancers, which are more likely to be advanced at the time of diagnosis, are managed with radiotherapy or chemoradiation. Surgery for oral cancers can be disfiguring and both surgery and radiotherapy have significant functional side effects. The development of new chemotherapy agents, new combinations of agents and changes in the relative timing of surgery, radiotherapy, and chemotherapy treatments may potentially bring about increases in both survival and quality of life for this group of patients. This review updates one last published in 2011.
OBJECTIVES
To determine whether chemotherapy, in addition to radiotherapy and/or surgery for oral cavity and oropharyngeal squamous cell carcinoma results in improved overall survival, improved disease-free survival and/or improved locoregional control, when incorporated as either induction therapy given prior to locoregional treatment (i.e. radiotherapy or surgery), concurrent with radiotherapy or in the adjuvant (i.e. after locoregional treatment with radiotherapy or surgery) setting.
SEARCH METHODS
An information specialist searched 4 bibliographic databases up to 15 September 2021 and used additional search methods to identify published, unpublished and ongoing studies.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) where more than 50% of participants had primary tumours in the oral cavity or oropharynx, and that evaluated the addition of chemotherapy to other treatments such as radiotherapy and/or surgery, or compared two or more chemotherapy regimens or modes of administration.
DATA COLLECTION AND ANALYSIS
For this update, we assessed the new included trials for their risk of bias and at least two authors extracted data from them. Our primary outcome was overall survival (time to death from any cause). Secondary outcomes were disease-free survival (time to disease recurrence or death from any cause) and locoregional control (response to primary treatment). We contacted trial authors for additional information or clarification when necessary.
MAIN RESULTS
We included 100 studies with 18,813 participants. None of the included trials were at low risk of bias. For induction chemotherapy, we reported the results for contemporary regimens that will be of interest to clinicians and people being treated for oral cavity and oropharyngeal cancers. Overall, there is insufficient evidence to clearly demonstrate a survival benefit from induction chemotherapy with platinum plus 5-fluorouracil prior to radiotherapy (hazard ratio (HR) for death 0.85, 95% confidence interval (CI) 0.70 to 1.04, P = 0.11; 7427 participants, 5 studies; moderate-certainty evidence), prior to surgery (HR for death 1.06, 95% CI 0.71 to 1.60, P = 0.77; 198 participants, 1 study; low-certainty evidence) or prior to concurrent chemoradiation (CRT) with cisplatin (HR for death 0.71, 95% CI 0.37 to 1.35, P = 0.30; 389 participants, 2 studies; low-certainty evidence). There is insufficient evidence to support the use of an induction chemotherapy regimen with cisplatin plus 5-fluorouracil plus docetaxel prior to CRT with cisplatin (HR for death 1.08, 95% CI 0.80 to 1.44, P = 0.63; 760 participants, 3 studies; low-certainty evidence). There is insufficient evidence to support the use of adjuvant chemotherapy over observation only following surgery (HR for death 0.95, 95% CI 0.73 to 1.22, P = 0.67; 353 participants, 5 studies; moderate-certainty evidence). Among studies that compared post-surgical adjuvant CRT, as compared to post-surgical RT, adjuvant CRT showed a survival benefit (HR 0.84, 95% CI 0.72 to 0.98, P = 0.03; 1097 participants, 4 studies; moderate-certainty evidence). Primary treatment with CRT, as compared to radiotherapy alone, was associated with a reduction in the risk of death (HR for death 0.74, 95% CI 0.67 to 0.83, P < 0.00001; 2852 participants, 24 studies; moderate-certainty evidence). AUTHORS' CONCLUSIONS: The results of this review demonstrate that chemotherapy in the curative-intent treatment of oral cavity and oropharyngeal cancers only seems to be of benefit when used in specific circumstances together with locoregional treatment. The evidence does not show a clear survival benefit from the use of induction chemotherapy prior to radiotherapy, surgery or CRT. Adjuvant CRT reduces the risk of death by 16%, as compared to radiotherapy alone. Concurrent chemoradiation as compared to radiation alone is associated with a greater than 20% improvement in overall survival; however, additional research is required to inform how the specific chemotherapy regimen may influence this benefit.
