EBV-Positive Diffuse Large B-Cell Lymphoma in Association with Polyurethane Textured Breast Implants: Case Report and Literature Overview.

OBJECTIVE: Lymphomas associated with breast implants are mostly of the T-cell type which typically present as a late-onset seroma or palpable mass adjacent to the implant. Primary lymphomas of the breast, in the absence of breast implants, are mostly of the B-cell type. However, we present a case of an Epstein-Barr virus-positive diffuse large B-cell lymphoma in a patient with polyurethane textured implants. CASE: A 75-year-old woman presented with a sudden onset of swelling in her right breast. Her medical history revealed a unilateral mastectomy at the age of 48 for an invasive ductal adenocarcinoma in her left breast. Reconstruction was performed using bilateral McGhan style 150 implants. Nine years later, she was diagnosed with Baker IV capsular contracture and bilateral rupture, as seen on magnetic resonance imaging. A complete capsulectomy with implant change (Polytech, Replicon® SL HP) and mastopexy on the right was performed. Given her history and the sudden onset of swelling, the situation was concerning. Ultrasound showed a large mass in contact with the implant and an effusion around it. After mastectomy with explantation and capsulectomy, she was diagnosed with an Epstein-Barr virus-associated diffuse large B-cell lymphoma (DLBCL) of the capsule in association with textured breast implants. CONCLUSION: We report the first case of polyurethane textured implant association with the rare entity of EBV+ DLBCL. Our aim is to renew awareness of the clinical significance of late periprosthetic seroma and highlight the need for documenting all cases to advance our understanding of breast implant-associated lymphoma.

Helpful hints in deciding what and when to operate after enzymatic debridement.

INTRODUCTION: In recent years, it has become clear that the burn eschar in deep burns can be selectively removed using the enzymatically debriding agent NexoBrid® (EDNX). In deep partial-thickness burns, such selective debridement preserves all non-injured dermis, which is sometimes sufficient for spontaneous re-epithelization. Nevertheless, it can be extremely challenging to determine exactly what and when to operate after an EDNX procedure. In this manuscript, we sought to investigate the clinical aspect of the enzymatically debrided wound bed of laser Doppler imaging (LDI)-confirmed deep dermal and full-thickness burns after NexoBrid® application. This to evaluate the residual wound healing capacity and implement specific indications for surgical therapy after enzymatic debridement. MATERIAL AND METHODS: Mainly LDI-blue areas, determined between 48 h and 5d after burn and afterwards treated with EDNX were selected. Six practical and three expert EDNX users evaluated the high-quality digital images of the wound beds immediately post NexoBrid® removal and after a 2 h wet-to-dry (WTD) dressing period. RESULTS: One hundred and two mainly LDI-blue areas in 32 patients were analyzed. Regarding the early decision-making, there were no significant differences in the wound bed evaluations, wound healing assessment and treatment decision of all 9 EDNX users post EDNX removal versus post WTD. Moreover, there was a good to excellent consensus between the practical and expert EDNX users in the individual wound bed evaluations. Even in the evaluation of a newly developed wound bed color code, with 7 different colors/patterns to choose from, the consensus was 80%. There was also an 84% consensus on the decision whether or not to operate. All mainly LDI-blue areas with incomplete enzymatic debridement, determined during clinical investigation by expert EDNX users, required surgery. Additionally, the expert investigators demonstrated that the following wound bed characteristics were independent predictors of the need for surgical treatment: visible fat lobules (p = 0.028), translucent fat lobules (p < 0.001), dermal step-off in the wound bed (p < 0.001), visible blood vessels (p < 0.001) and coagulated blood vessels (p = 0.023). Also, higher color code ranges on our own developed wound bed classification were significantly related to a surgical intervention (p = 0.006). When including the LDI flux values, the perfusion units were significantly different (p < 0.001) between the exclusively LDI-blue areas treated conservatively (mean 145.7) and the areas ultimately treated with autografts (mean 119.5). CONCLUSION: To the best of our knowledge, this study is the first to address the clinical wound bed evaluation of LDI-confirmed deep burns after NexoBrid® application. Based on our results, it is recommended to evaluate the wound bed twice: immediately after removing NexoBrid® to assess the viability of the wound bed and after the WTD period to reach a more complete decision. During these evaluations, wound bed characteristics such as incomplete debridement, visible and/or translucent fat lobules, visible and/or coagulated blood vessels and a dermal step-off in the wound bed combined with a higher range (4-5) in the newly developed wound bed color code should lead to an early and reliable decision for skin grafting. For burn centers using LDI, mean flux values below 119.5PU - in addition to the above-mentioned wound bed evaluation - are a clear indicator for surgical therapy.

Injuries associated with electronic nicotine delivery systems: A systematic review.

BACKGROUND: Since its introduction on the market in 2007, the number of reports on injuries caused by the overheating, ignition, or explosion of electronic nicotine delivery systems (ENDSs) has increased significantly. These injuries appear to have different causes, the most important one being lithium-ion battery overheating to the point of ignition or explosion. METHODS: A literature search for all relevant studies concerning ENDS-related traumatic injuries of all kinds was conducted, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses protocol. The search started with the first introduction of ENDSs in 2007 and ended February 2020. Articles included were reports on patients who sustained flame, chemical, or traumatic injuries of the skin, soft tissue, and/or bone, related to the use of ENDSs. RESULTS: This systematic review includes 180 patients from 41 case series and reports, published between 2016 and 2020. The mean age was 30.8 years (range, 17-59 years) with an overall male predominance (168 of 180 patients, 93%). In most injuries, multiple anatomical sites were affected, with the thigh/lower limb being the most commonly injured area (77%) followed by the upper limb/hand (43%). Eighty-two patients (51%) required a surgical treatment, 70 patients (43%) were managed conservatively with dressings or ointments, and 9 patients (6%) underwent enzymatic debridement. Thirty-five percent of all patients underwent skin grafting. CONCLUSION: Injuries from overheating, ignition, or explosion of ENDSs are an emerging, underreported, and underresearched issue. There is a need for increased regulation of ENDSs and improved surveillance of related injuries. Both health care providers and consumers should be made aware of the risks and be advised about how to safely handle these devices. In contrast to other articles, this systematic review includes all types of injuries related to ENDS overheating, ignition, and explosion. To our knowledge, this is the most extensive systematic review performed to date. LEVEL OF EVIDENCE: Review article, level III.

Enzymatic debridement as an effective treatment for combined flame and chemical burns caused by e-cigarettes.

Since its introduction on the market in 2007, the number of reports on injuries caused by the ignition or explosion of electronic nicotine delivery systems (ENDS) has increased significantly. Two male patients have been treated at our burn center, the for ENDS-related injuries. Their batteries came into contact with metal objects stored in their pants pockets, resulting in a short circuit and finally ignition. In both patients, the combined flame and chemical burn wounds were initially irrigated with water upon arrival at the emergency department, leading to increased levels of pain. In our burn center, the wounds were extensively cleansed which led to a subsequent drop in NRS-scores. Laser Doppler Imaging showed a clear indication for surgery as both patients suffered a partial-thickness burn, with one patient having a patch of full-thickness burn as well. We swiftly performed an enzymatic debridement in both patients, followed by conservative wound management. Although enzymatic debridement is not generally recommended in the treatment of chemical burns, we successfully made use of this treatment option. Different authors advocate the use of mineral oils to irrigate or cover alkali burns, as contact between the chemical compounds and water can set off an exothermic reaction, leading to further injury. We believe that a hypertonic rinsing solution could be recommended as well in an emergency setting and we want to stress the importance of rapid removal of the chemical compounds in suspected chemical burns as well as swift debridement.

Male-to-female gender affirmation surgery: breast reconstruction with Ergonomix round prostheses.

People with gender dysphoria are becoming more prevalent and more universally accepted. Social, hormonal, and surgical gender transition are able to substantially improve their quality of life. Various gender affirmation surgery (GAS) options are available to address gender dysphoria in the male-to-female (MtF) population, including facial and chest feminization, body contouring,  and genital surgery. While hormone replacement therapy may result in some degree of breast development, it is often insufficient to effectively result in an adequate female-like breast contour. The creation of a female chest is generally the first surgical step in the transition. The primary aim of this manuscript is to describe the surgical technique with ergonomix round prostheses used at our high-volume GAS center and to point out how anatomical differences between trans-female and cis-female patients impact surgery. Furthermore, we provide an overview of the demographic data and postoperative outcomes.

Free Bipedicled Radial Forearm and Posterior Interosseous Artery Perforator Flap Phalloplasty.

INTRODUCTION: The free radial forearm (FRFA) flap is universally still considered as the gold standard technique in penile reconstruction. Typically, a considerably large flap is required, often involving almost the entire circumference of the forearm. Partial necrosis may occur at the distal-most (dorsoradial) part of the flap as a result of insufficient perfusion. AIM: To describe a new technique using the posterior interosseous artery (PIOA) to supercharge FRFA phalloplasty. METHODS: In a 12-month period, all patients having FRFA flap phalloplasty were enrolled. Perioperative, after complete flap dissection, an indocyanine green perfusion scan was performed. In case of insufficient perfusion at the distalmost part of the flap, a supramicrosurgical anastomosis was performed between the FRFA pedicle and the PIOA (artery only). MAIN OUTCOME MEASURES: Studied outcomes included the rate of marginal necrosis, surgical time, postoperative posterior interosseous nerve damage and urethral complications (fistula, stenosis or necrosis). RESULTS: A total of 27 FRFA flap phalloplasties was performed. Anastomosis of the PIOA was needed in 15 cases. No marginal necrosis was observed in these cases. There were no cases of postoperative posterior interosseous nerve damage. There were no significant differences in urethral complications (fistula, stenosis or necrosis) between the 2 groups. CLINICAL IMPLICATIONS: In selected cases where insufficient perfusion of the dorsoradial part of the flap is present, patients may benefit from arterial supercharging to prevent postoperative marginal necrosis. STRENGTH & LIMITATIONS: Strengths include a single surgeon, thus lending continuity of skill and technique, a consecutive series, and 100% short-term follow-up. Limitations include single institution series and a limited number of patients. CONCLUSION: Arterial supercharging is effective in improving perfusion of large FRFA flaps used in phalloplasty when dorsoradial hypoperfusion is detected on an indocyanine green perfusion scan. It is a technically challenging addition to the standard technique because of the small size of the vessels, the close relationship between the PIOA and the posterior interosseous nerve, and the vulnerability of the newly constructed intra-flap anastomosis.

Free flaps for lower limb soft tissue reconstruction in children: Systematic review.

BACKGROUND: Since the first reports on microsurgery in children, there has been an evolution in the reconstruction of soft tissue defects as evidenced by a shift to free flaps as the first-line treatment. METHODS: The primary objective of this systematic review was to compare the complication rate of free perforator/fasciocutaneous flaps with free muscular/myocutaneous flaps in pediatric lower limb soft tissue reconstructions. The secondary objective was to evaluate the frequency and severity of complications for both reconstructive options. A search was performed in the databases PubMed, Web of Science, Embase, Scopus, and Cochrane Library depending on predefined inclusion criteria. RESULTS: The evolution to perforator flaps from muscular and myocutaneous flaps is reflected in this systematic review as demonstrated by the anterolateral thigh (ALT) flap, which is the most common reconstructive option with a very low complication rate (11.3%) and flap loss. The latissimus dorsi (LD) flap was the second most frequently reported reconstruction with a complication rate comparable with that of the thoracodorsal artery perforator (TDAP) flap (32% vs. 39%, respectively), but the former suffers few failures. The radial forearm (RFA) fasciocutaneous flap can be considered a good alternative for ALT and TDAP flaps with a very low complication rate (16%) and no flap loss. CONCLUSIONS: The ALT flap is considered the best reconstructive method for pediatric lower limb soft tissue defects. More adequate prospective studies specifically concerning free flap reconstructions for lower limb defects in children are necessary in the future to provide guidelines for treatment and optimize outcomes in the long term.

Creation of Clitoral Hood and Labia Minora in Penile Inversion Vaginoplasty in Circumcised and Uncircumcised Transwomen.

Gender dysphoria, the incongruence between anatomical sex and gender identity, is estimated to affect 1 percent of the population. Creation of a feminine vulva with labia minora remains a technical challenge for surgeons, especially in circumcised patients. The authors present the technique developed by the senior author (S.M.) that uses prepuce skin in uncircumcised patients or distal shaft skin in circumcised patients for creation of both clitoral hood and labia minora. A retrospective case review was conducted of all penile inversion vaginoplasties performed by the senior author between 2014 and 2016. Patient characteristics, history of circumcision, and revision surgery were recorded. Surgical technique to create and inset the neoclitoris and labia minora in a single-stage penile inversion vaginoplasty is described in detail. A total of 161 penile inversion vaginoplasty operations were performed. Creation of labia minora and clitoral hood was achieved in all patients, with 4.3 percent undergoing an early intervention for bleeding or dehiscence and 5.6 percent requiring late revision surgery for diverted urinary stream. Average length of follow-up was 29 months. Age, hormonal therapy time, body mass index, smoking, and diabetes were the investigated risk factors for postoperative complications, but no significant correlations were found. All patients met the standards of care set forth by the World Professional Association for Transgender Health. Creation of the clitoral hood and labia minora during penile inversion vaginoplasty is achievable in both circumcised and uncircumcised patients, with good aesthetic results and a low revision surgery rate. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

A New Technique for Coronaplasty in Penile Reconstruction.

BACKGROUND: The coronaplasty is an important step of the phalloplasty procedure as it creates a prominent coronal ridge and a constricted coronal sulcus, resulting in the transformation of a regular skin flap into a flap resembling a circumcised penis. AIM: The aim of this article is to describe our new coronaplasty technique that exploits opposing contracting forces of 2 different skin grafts to hold the shape of a thick, distally based skin flap, resulting in a natural looking neo-phallus. METHODS: A distally based flap is raised at the junction of the middle and distal thirds of the neo-phallus. The dissection continues until adequate mobilization is obtained, so the flap can stand almost perpendicular to the axis of the shaft. 2 separate full-thickness skin grafts are harvested and placed: the first at the raw undersurface of the flap, the second at the flap's donor site. To make the sulcus deeper and to define the ridge, the lower part of the graft placed on the undersurface of the distal flap is sutured with tacking sutures. Depending on the type of flap used this procedure can be done during the phalloplasty procedure itself (axial flaps) or at least 1 week later (perforator flaps). OUTCOMES: The new technique that we developed shows a more distinct coronal sulcus and coronal ridge, long-lasting results, and a more aesthetically pleasing and natural-appearing glans penis. RESULTS: The harvested distal flap is progressively thicker and not folded, resulting in a more naturally looking ridge. The donor site is deeper than other techniques, creating a well-defined sulcus. By using 2 skin grafts the opposing force vectors increase the projection of the ridge and the deepness of the sulcus. CLINICAL TRANSLATION: This technique results in a more prominent glans penis and is an important step in creating an almost naturally looking neo-phallus. CONCLUSIONS: This procedure can be applied to all different kind of flaps used for phalloplasty, both in an immediate or delayed fashion. As grafts are used, partial or complete graft lost can appear. Furthermore, attention must be paid not to incise the distal flap too deep so vascularity to the distal part of the flap will not be impaired. A continuous search to optimize the aesthetic outcome of the phalloplasty procedure is necessary and with this new coronaplasty technique we hope to raise attention and take another step toward creating "the real thing."
