Review
Male-to-Female (MtF) breast cancer events have been reported since 1968 however, MtF patients' risk of breast cancer remain unclear. Following PRISMA guidelines, electronic databases and grey literature were searched April 2018 to identify breast cancer events in MtF transgender persons. Screening and data extraction were independently performed in duplicate by two reviewers. Study quality was assessed using a component-based system. Qualitative analysis was performed on study characteristics, patient demographics, breast cancer characteristics, and breast cancer presentation and management. Eighteen articles met inclusion criteria representing 22 breast cancer events. Median age at breast cancer diagnosis was 51.5 years. The most common breast cancer type was adenocarcinomas (59.1%) and half of the breast cancers were hormone sensitive, with estrogen receptor positive status in 10 of 19 tested and progesterone receptor positive status in 5 of 14 tested. The most common presentation was breast lump (n = 6, 42.9%), two patients had palpable lymph nodes at presentation (14.3%), and six patients eventually developed metastases (42.9%). Seven patients had a recorded positive breast cancer family history and one was BRCA2 positive. Breast cancers were treated with mastectomies (simple, modified radical, and radical), wide local excision, lumpectomy, or were unclear. Four patients received hormone therapy (23.5%), two received radiation (11.8%), and seven received chemotherapy (41.2%). Breast cancer is present in MtF patients and commonly presents at a younger age with a palpable mass. Major gaps in the literature include lack of transgender population data and long term follow-up. This work highlights the need for screening recommendations.

Review
PURPOSE
To sum all available evidence regarding mesh or mesh fixation material intestinal erosion following inguinal hernia repair and identify the parameters that lead to early (< 6 months) versus late (> 6 months) symptom presentation.
METHODS
A systematic literature search of the MEDLINE, Scopus and Google Scholar databases was undertaken to identify relevant studies published up to June 2020.
RESULTS
A total of 54 case reports or cases series, incorporating 57 intestinal erosions were identified. Overall, 13 patients (23%) experienced early intestinal erosions occurring during the first 6 postoperative months while the remaining 44 events (67%) occurred after 6 months. Patients presented most commonly with symptoms of acute obstruction (n = 18, 31.5%), followed by signs of a palpable inguinal mass in 15 patients (26.3%). The late presentation group exhibited significantly more cases of mesh erosion when compared to the early presentation group (100% versus 46.2%, respectively, p < 0.001). Conversely, early presenting cases were more often associated with mesh fixation material erosion (53.8% versus 6.8% in the late group, p < 0.001) and were more likely to develop symptoms of acute intestinal obstruction (61.5% versus 22.8%, p = 0.01). An open primary procedure was more common in late presenting cases (65.9% versus 7.7%, p < 0.001) while early presentation was linked to minimally invasive primary procedures (92.3% versus 34.2%, p < 0.001). Bowel resection was more frequently required in late presenting cases (84.1% versus 46.2%, p = 0.009).
CONCLUSIONS
Intestinal erosion from prosthetic material is a rare complication of hernia repair leading to considerable morbidity. Prompt operative repair is key in avoiding catastrophic consequences.

Review
Wire-guided localisation (WGL) has been the gold-standard for localising non-palpable breast lesions before excision. Due to its drawbacks, various wireless alternatives have been developed, including LOCalizer™, which is based on radio-frequency identification (RFID) technology. In this systematic review, we consulted EMBASE, Medline and PubMed databases using appropriate search terms regarding the use of RFID technology in the localisation of occult breast lesions. Retrospective and prospective studies were included if they quoted the number of patients, rate of successful placement, retrieval rate, margin positivity rate and the re-excision rate. In addition, studies comparing RFID to WGL were also included and analysed separately. Seven studies were included in this systematic review spanning 1151 patients and 1344 tags. The pooled deployment rate was 99.1% and retrieval rate was 100%. Re-excision rate was 13.9%. One complication was identified. Two studies compared RFID with WGL (128 vs. 282 patients respectively). For both techniques the re-excision rate was 15.6% (20/128 vs. 44/282 respectively, value is 0.995). Based on our review, LOCalizer™ is safe and non-inferior to WGL in terms of successful localisation and re-excision rates. However, further research is required to assess the cost effectiveness of this approach and its impact on the aesthetic outcome compared with WGL and other wire free technologies to better inform decision making in service planning and provision.

Review
BACKGROUND
Autologous fat grafting (AFG) is a versatile technique in reconstructive and cosmetic surgery. Graft processing is a key source of variability resulting in unreliable clinical outcomes, with no consensus on the optimal methodology. This systematic review identifies the evidence base supporting different processing paradigms.
METHODS
A systematic literature search was conducted using the PubMed, Scopus and The Cochrane Foundation databases. Studies comparing AFG processing methods and reporting long-term patient outcomes were identified.
RESULTS
Twenty-four studies (2413 patients) were identified. Processing techniques evaluated included centrifugation, decantation, washing, filtration, gauze rolling, as well as commercial devices and adipose-derived stem/stromal cell (ASC) enrichment methods. Objective volumetric and subjective patient-reported outcomes were discussed. There was a variable reporting of complications and volume retention rates. Complications were infrequent; palpable cysts (0-20%), surgical-site infections (0-8%) and fat necrosis (0-58.4%) were the most reported. No significant differences in long-term volume retention between techniques were found in AFG in the breast. In head and neck patients, greater volume retention was documented in ASC enrichment (64.8-95%) and commercial devices (41.2%) compared to centrifugation (31.8-76%).
CONCLUSIONS
Graft processing through washing and filtration, including when incorporated into commercial devices, results in superior long-term outcomes compared to centrifugation and decantation methods. ASC enrichment methods and commercial devices seem to have superior long-term volume retention in facial fat grafting.

Meta-Analysis
Identifying patients at risk of difficult intravenous access (DIVA) and increasing the success rates of peripheral intravenous catheterization (PIVC), preferably on the first catheterization attempt, is of clinical importance. The aim of this study was to compare the use of dynamic ultrasound guidance for PIVC with the traditional technique of visualization and palpation in patients with predicted DIVA. A systematic review and meta-analysis comparing ultrasound-guided PIVC with the traditional technique was performed. Data were systematically collected through MEDLINE and EMBASE databases from inception to March 2021. Eligibility criteria included randomized controlled trials performed on patients meeting criteria for difficult catheterization comprising either (a) no palpable or visible veins, (b) previous history of difficult venous catheterization, (c) patient age less than 4 years, (d) suspicion of difficult catheterization by operator, or (e) two or more unsuccessful attempts using the traditional technique before enrollment were included. For all outcomes, a random-effects meta-analysis using the DerSimonian and Laird method was performed. The primary outcome was the first-attempt success rate, and the secondary outcomes were the overall success rate and the number of attempts for successful intravenous catheterization. Bias was assessed using the Revised Cochrane Risk of Bias tool. Seven studies with a total of 994 patients were included. Patients comprised both children and adults and settings included operating rooms, emergency departments, and intensive care units. Ultrasound guidance was associated with a higher first-attempt success rate (OR, 3.07; 95% CI, 1.66-5.65; P < 0.001). For the secondary outcomes, ultrasound guidance was associated with a higher overall success rate (OR, 3.02; 95% CI, 1.04-8.79; P = 0.04); however, this finding did not meet statistical significance in a sensitivity analysis (OR, 2.90; 95% CI, 0.71-11.93; P = 0.14). Ultrasound was not associated with a significantly different number of attempts compared with the traditional technique (difference in means, 0.14; 95% CI, -0.32 to 0.05; P = 0.15). The use of ultrasound guidance resulted in a three-fold increase in odds for the first-attempt success rate in patients with predicted DIVA compared with the traditional technique of PIVC.

Meta-Analysis
The preoperative localisation of non-palpable lesions guided by breast imaging is an important and required procedure for breast-conserving surgery. We conducted a systematic review and meta-analysis of the literature on the comparative impact of different techniques for guided surgical excision of non-palpable breast lesions from reports of clinical or patient-reported outcomes and costs. A literature search of PubMed, ISI, SCOPUS and Cochrane databases was conducted for relevant publications and their references, along with public documents, national and international guidelines, conference proceedings and presentations. From 5720 retrieved articles screened through title and abstract, 5346 were excluded and 374 assessed for full-text eligibility. For data extraction and quality assessment, 49 studies were included. Results of this review demonstrate that Radioactive Seed Localisation (RSL) and Radioactive Occult Lesion Localisation (ROLL) outperform Wire in terms of involved margins and reoperations. Between RSL and ROLL, there is a tendency to favour RSL. Similarly, Clip-guided localisation seems preferred when compared to ROLL, however further studies are needed. In summary, there seems to exist evidence that RSL and ROLL are better than Wire, representing potential alternatives, with a quick learning curve, better scheduling and management issues. Although, for recent techniques, more research is needed in order to achieve the same level of evidence.

Review
To provide an overview of existing prediction models for successful ECV, and to assess their quality, development and performance. We searched MEDLINE, EMBASE and the Cochrane Library to identify all articles reporting on prediction models for successful ECV published from inception to January 2015. We extracted information on study design, sample size, model-building strategies and validation. We evaluated the phases of model development and summarized their performance in terms of discrimination, calibration and clinical usefulness. We collected different predictor variables together with their defined significance, in order to identify important predictor variables for successful ECV. We identified eight articles reporting on seven prediction models. All models were subjected to internal validation. Only one model was also validated in an external cohort. Two prediction models had a low overall risk of bias, of which only one showed promising predictive performance at internal validation. This model also completed the phase of external validation. For none of the models their impact on clinical practice was evaluated. The most important predictor variables for successful ECV described in the selected articles were parity, placental location, breech engagement and the fetal head being palpable. One model was assessed using discrimination and calibration using internal (AUC 0.71) and external validation (AUC 0.64), while two other models were assessed with discrimination and calibration, respectively. We found one prediction model for breech presentation that was validated in an external cohort and had acceptable predictive performance. This model should be used to council women considering ECV.

Review
UNLABELLED
The occurrence of blistering eruptions in childhood Henoch-Schönlein syndrome has been so far addressed exclusively in individual case reports. To describe epidemiology, clinical presentation, and therapeutic options in Henoch-Schönlein patients ≤18 years of age with blistering eruptions, we completed a systematic literature search. For the final analysis, we retained 39 reports. Ten children with blisters were found in 7 (1.5%) case series containing a total of 666 unselected pediatric Henoch-Schönlein cases. We also found 41 individually documented cases of Henoch-Schönlein syndrome with blistering eruptions. Blistering eruptions and purpura were distributed very similarly, blisters developed concomitantly with palpable purpura or with a latency of ≤14 days, and 80% of the cases remitted within 4 weeks with a similar course in children managed expectantly and in those managed with steroids.
CONCLUSION
Blistering eruptions are rare in Henoch-Schönlein syndrome. They can be a source of diagnostic dilemma but do not have any prognostic value since they almost always spontaneously subside within 4 weeks. What is known: • Textbooks and reviews marginally refer to the occurrence of blistering eruptions in children with Henoch-Schönlein syndrome. What is new • Blistering eruptions occur in <2% of cases. • Blisters and purpura are distributed similarly, blisters develop concomitantly with purpura or with a latency of ≤14 days. • Almost all cases remit within 4 weeks with a similar course in children managed expectantly and in those managed with systemic steroids.

PURPOSE
Classically, wire-guided localization (WGL) is used for the localization of non palpable breast lesions. On the other hand, many studies report a newer technique called radioactive seed localization (RSL). The purpose of our study was a systematic review and meta analysis of the two techniques regarding the rate of positive margins and the quantity of excised tissue.
METHODS
Our study searched publications up to March 24th 2018 in Medline, Embase and Cochrane Library regarding studies comparing the two techniques of localization of subclinical lesions with WGL or RSL using technetium 99m as radioactive agent. The primary target was the rate of positive margins and the second was the rate of second surgery for reexcision. Revman5.3 and STATE12.0 were used for the statistics.
RESULTS
Five randomized controlled trials (RCTs) and 13 cohort studies comprising 3879 breast cancer patients were included. RSL was significantly superior than WGL both in better margin status (RR=0.72, 95% CI 0.56-0.92, p=0.01) and reduced reoperation rate (RR=0.68, 95% CI 0.52-0.88, p=0.004). Subgroup analysis of RCTs showed no different ability of both techniques in terms of free margin status (RR=0.85, 95% CI 0.55-1.31, p=0.46) and reoperation rate (RR=0.80, 95% CI 0.48-1.32, p=0.38). Further subgroup analysis excluding three studies with different ductal carcinoma in situ (DCIS) proportion exhibited same efficacy in margin negativity (RR=0.83, 95% CI 0.69-1.01, p=0.07) and further operation rate (RR=0.85, 95% CI 0.71-1.01, p=0.07).
