Review
OBJECTIVE
The larynx is the most common site of localized head and neck amyloidosis. Our study aimed to review the clinical features, treatments, and outcomes associated with localized laryngeal amyloidosis (LA). We also compared these features between two different time periods to evaluate the evolution of LA management.
METHODS
A literature search using PubMed, CINAHL, Embase, and Cochrane Library identified cases of LA published between 1891 and 2021. Biopsy-proven cases of localized LA were included. Non-English studies, animal studies, and reviews were excluded.
RESULTS
282 patients (1891-1999: 142 patients, 2000-2021: 140 patients) from 129 studies were included. Results are reported as 1891-2000 vs. 2000-2021: Mean age was 48.5 years (range, 8-90 years) vs. 46.0 years (range, 9-84 years). The most common presenting symptoms were dysphonia (n = 30, 95 % vs. n = 127, 96 %) and difficulty breathing (n = 37, 27 % vs. n = 35, 27 %). A total of 62 (44 %) vs. 46 (33 %) lesions were found in the true vocal folds and 35 (25 %) vs. 59 (42 %) were found in the false vocal folds. 133 (94 %) vs. 137 (98 %) patients underwent surgical interventions to investigate and/or treat LA. Recurrent LA was reported in 27 (19 %) vs. 33 (24 %) patients with a mean time to recurrence of 25.4 months (range, 0.3-132 months) vs. 34.5 months (range, 0.8-144 months). Of cases reporting survival rate, 104 (97 %) vs. 107 (99 %) were alive at source study endpoints.
CONCLUSION
LA typically exhibits an indolent course; therefore, early intervention may address longstanding symptoms. Recurrent disease poses a clinical challenge in patients with LA.

Meta-Analysis Review
BACKGROUND
Melanoma is the most lethal skin cancer. Excision biopsy is generally recommended for clinically suspicious pigmented lesions; however, a proportion of cutaneous melanomas are diagnosed by shave biopsy. A systematic review was undertaken to investigate the impact of shave biopsy on tumor staging, treatment recommendations, and prognosis.
METHODOLOGY
The MEDLINE, Embase, and Cochrane Library databases were searched for relevant articles. Data on deep margin status on shave biopsy, tumor upstaging, and additional treatments on wide local excision (WLE), disease recurrence, and survival effect were analyzed across studies.
RESULTS
Fourteen articles from 2010 to 2020 were included. In total, 3713 patients had melanoma diagnosed on shave biopsy. Meta-analysis revealed a positive deep margin in 42.9% of shave biopsies. Following WLE, change in tumor stage was reported in 7.7% of patients. Additional treatment was recommended for 2.3% of patients in the form of either further WLE and/or sentinel lymph node biopsy. There was high heterogeneity across studies in all outcomes. Four studies reported survival, while no studies found any significant difference in disease-free or overall survival between shave biopsy and other biopsy modalities.
CONCLUSIONS
Just over 40% of melanomas diagnosed on shave biopsy report a positive deep margin; however, this translated into a change in tumor stage or treatment recommendations in relatively few patients (7.7% and 2.3%, respectively), with no impact on local recurrence or survival among the studies analyzed.

BACKGROUND
Burn injuries are the fourth most common traumatic injury, causing an estimated 180,000 deaths annually worldwide. Superficial burns can be managed with dressings alone, but deeper burns or those that fail to heal promptly are usually treated surgically. Acute burns surgery aims to debride burnt skin until healthy tissue is reached, at which point skin grafts or temporising dressings are applied. Conventional debridement is performed with an angled blade, tangentially shaving burned tissue until healthy tissue is encountered. Hydrosurgery, an alternative to conventional blade debridement, simultaneously debrides, irrigates, and removes tissue with the aim of minimising damage to uninjured tissue. Despite the increasing use of hydrosurgery, its efficacy and the risk of adverse events following surgery for burns is unclear.
OBJECTIVES
To assess the effects of hydrosurgical debridement and skin grafting versus conventional surgical debridement and skin grafting for the treatment of acute partial-thickness burns.
SEARCH METHODS
In December 2019 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that enrolled people of any age with acute partial-thickness burn injury and assessed the use of hydrosurgery.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, data extraction, 'Risk of bias' assessment, and GRADE assessment of the certainty of the evidence.
MAIN RESULTS
One RCT met the inclusion criteria of this review. The study sample size was 61 paediatric participants with acute partial-thickness burns of 3% to 4% total burn surface area. Participants were randomised to hydrosurgery or conventional debridement. There may be little or no difference in mean time to complete healing (mean difference (MD) 0.00 days, 95% confidence interval (CI) -6.25 to 6.25) or postoperative infection risk (risk ratio 1.33, 95% CI 0.57 to 3.11). These results are based on very low-certainty evidence, which was downgraded twice for risk of bias, once for indirectness, and once for imprecision. There may be little or no difference in operative time between hydrosurgery and conventional debridement (MD 0.2 minutes, 95% CI -12.2 to 12.6); again, the certainty of the evidence is very low, downgraded once for risk of bias, once for indirectness, and once for imprecision. There may be little or no difference in scar outcomes at six months. Health-related quality of life, resource use, and other adverse outcomes were not reported.
AUTHORS' CONCLUSIONS
This review contains one randomised trial of hydrosurgery versus conventional debridement in a paediatric population with low percentage of total body surface area burn injuries. Based on the available trial data, there may be little or no difference between hydrosurgery and conventional debridement in terms of time to complete healing, postoperative infection, operative time, and scar outcomes at six months. These results are based on very low-certainty evidence. Further research evaluating these outcomes as well as health-related quality of life, resource use, and other adverse event outcomes is required.

PURPOSE
Cavity shaving (CS) is a surgical technique used in the treatment of breast cancer (BC). It may reduce margin positivity in histologic assessment and consequently reduces re- excision rates in breast conserving surgery (BCS). The evidence for this assumption is described in the present review.
METHODS
A systematic review of relevant literature in English from January 1999 to April 2019 was conducted. The analysis included studies on CS and its effects on re-excision rates and margin positivity. We searched PubMed databases for relevant publications. In total, 22 studies were included in the present review.
RESULTS
The benefit from CS on re-excision rates and histologic margin positivity was variable. Out of 22 studies, 17 reported a reduction in both re-excision rates and histologic margin positivity in margin shaved patients. Four studies could not find a significant reduction of second surgeries and residual tumor rates. One study suggested that CS after BCS was superior to single BCS only in subgroup analysis in IDC tumors.
CONCLUSION
CS is a surgical technique that was shown to reduce re-excision and margin positivity rates in most of the studies. Furthermore, it can be a useful tool to assess specimen margins and detect multifocality.

Meta-Analysis
OBJECTIVE
The recurrence rate after colorectal surgery for endometriosis is up to 50% at 5 years. The aim of the current review and meta-analysis was to assess recurrence associated with shaving, disc excision, and segmental resection for endometriosis with colorectal involvement.
DATA SOURCES
A systematic review was performed by searching the PubMed, ClinicalTrials.gov, EMBASE, Cochrane Library, and Web of Science databases for publications before February 28, 2019, using the terms "colorectal endometriosis" and "recurrence" in English. The outcome measure was histologically proven recurrence 1 year after the index surgery.
METHODS OF STUDY SELECTION
Studies rated as good or fair by a study quality assessment tool were included. Two reviewers independently assessed the quality of the studies; discrepancies were discussed, and if a consensus was not reached, a third reviewer was consulted.
TABULATION, INTEGRATION, AND RESULTS
Of 156 relevant published trials, 41 were systematically reviewed and 4 were included in the meta-analysis. The risk of recurrence was higher after rectal shaving than after both segmental resection (odds ratio [OR], 5.53; 95% confidence interval [CI], 2.33-13.12; I = 0%; p = .001) and disc excision for histologically proven recurrence (OR, 3.83; 95% CI, 1.33-11.05; I = 0%; p = .01). This difference was not significant when comparing disc excision with segmental resection (OR, 2.63; 95% CI, 0.8-8.65; I = 0%; p = .11).
CONCLUSION
The current analysis shows that the risk of recurrence is lower when segmental resection or disc excision is performed than when rectal shaving is performed. This finding is important when deciding the most appropriate surgical management.

The objective of this study is to identify the incidence and characteristics of cases with positive margins on wide local excision for cutaneous melanoma of the head and neck (CMHN) and therefore provide a potential basis for selectively delaying reconstruction pending final histological clearance of melanoma. A systematic review of English language articles was performed on studies retrieved from PubMed and Web of Science. Original investigations published between July 1999 and June 2018 reporting on margin status of CMHN wide local excision specimens were included in the review. The incidence of positive margins after definitive resection for cutaneous melanoma in the literature ranges from 6 to 20.9%. The incidence is higher in cases of advanced patient age, diagnosis by shave biopsy, lentigo maligna melanoma subtype, desmoplastic subtype, tumor thickness, and ulceration. Delayed reconstruction remains the most oncologically sound decision, allowing for interpretation of margin status on paraffin-embedded tissue sections. However, resection and the resultant defect closure in a single stage is more expedient and potentially a more efficient use of resources. The risk-benefit ratio of immediate versus delayed reconstruction must be considered for each case. The incidence of positive margins is higher in cases of advanced patient age, diagnosis by shave biopsy, lentigo maligna melanoma subtype, desmoplastic subtype, increasing tumor thickness, and the presence of ulceration; delayed reconstruction should be strongly considered in these cases.

Meta-Analysis
AIMS
To evaluate comparative outcomes of breast-conserving surgery (BCS) of breast cancer with and without cavity shaving.
METHODS
A systematic search of multiple electronic data sources was conducted, and all randomised controlled trials (RCTs) comparing BCS with or without cavity shaving for breast cancer were included. Positive margin rate, second operation rate, operative time, post-operative haematoma, cosmetic appearance and budget cost were the evaluated outcome parameters for the meta-analysis.
RESULTS
Six RCTs reporting a total number of 971 patients; 495 of these underwent BCS plus shaving (BCS + S), and 473 underwent BCS alone were included. BCS + S showed significantly lower positive margin rate (Risk Ratio [RR] 0.40, P = 0.00001) and second operation rate (RR 0.38, P = 0.00001). BCS + S demonstrated longer operative time than BCS (79 ± 4 min vs 67 ± 3 min, Mean Difference 12.14, P = 0.002), and there was no significant difference in the risk of post-operative haematoma (RR 0.33, P = 0.20).
CONCLUSION
BCS + S is superior to BCS in terms of positive margins rate and second operation rate. Operative time is longer when cavity shaving is performed.
