Background: The aim of this study was to compare the use of pedicled local (PFs) versus random pattern flaps (RpFs) in foot and ankle reconstruction in patients with chronic, nonhealing wounds. Methods: A single-center, retrospective review of 204 patients with 118 PFs and 86 RpFs was performed. The primary outcome included rates of limb salvage. Results: PFs were used more often in the hindfoot (44.1% versus 30.2%, P = 0.045), lateral and medial surface (39.8% versus 18.6%, P = 0.001), and wounds containing exposed bone and hardware (78.8% versus 62.8%, P = 0.018). RpFs were used more for forefoot (19.8% versus 10.2%, P = 0.053) and plantar defects (58.1% versus 30.3%, P = 0.000). RpFs had a higher rate of immediate success (100% versus 95.8%, P = 0.053), with no significant differences in rate of long-term limb salvage (77.1% versus 69.8%, P = 0.237). PFs had higher rates of ischemia requiring intervention (11.0% versus 3.5%, P = 0.048). RpFs had a higher rate of minor amputations (15.12% versus 6.8%, P = 0.053) but similar rates of major amputation (15.1% versus 16.1%, P = 0.848). There were no significant differences in rates of mortality or ambulatory status. Conclusions: Both RpFs and PFs remain reliable options to reconstruct defects of the foot and ankle. Optimizing the use of each flap type should consider wound characteristics. RpFs are preferred for dorsal and plantar defects, whereas PFs are protective for minor infections and preferred for deeper wounds despite a higher rate of partial necrosis.

Background: In this systematic review, we assessed the therapeutic efficacy and safety of Clostridium histolyticum collagenase (CCH) and tissue subcision (TS) for treating cellulite, which ranges from subtle to pronounced lesions. Methods: A systematic review was performed following PRISMA guidelines for CCH and TS treatment to the thigh and gluteal regions. A proportion meta-analysis was then conducted using Stata statistical software. Results: A total of 14 studies were incorporated into the final analysis. Nine focused on TS and five on CCH injection, collectively reporting outcomes for 1254 patients. Of these, 465 received CCH injection and 789 underwent subcision. For bruising, rates were 89% [95% confidence interval (CI), 71%–96%] with CCH injection and 99% (95% CI, 85%–99%) for subcision; pain requiring analgesic was reported at 74% (95% CI, 55%–87%) for CCH and 60% (95% CI, 43%–76%) for subcision; both showed induration at 7% (95% CI, 5%–11% for CCH, 95% CI, 2%–25% for subcision), whereas skin discoloration was higher post-CCH injection at 16% (95% CI, 10%–26%) compared with 7% (95% CI, 5%–10%) postsubcision. Conclusions: Both CCH and TS seem effective treatments for cellulite. However, upon evaluating the adverse outcomes between the two modalities, subcision demonstrated a higher incidence of bruising, albeit similar rates of induration compared with CCH injection. Conversely, the CCH injection group manifested a higher propensity for pain requiring analgesia and notably exhibited increased instances of skin discoloration compared with their subcision patient group. Further standardized research is crucial for more informed cellulite treatment decisions and for comparing efficacy, safety, and cost-effectiveness between TS and CCH.

Background: Endometriosis is a common gynecological disorder described as the presence of functional endometrial tissue outside the uterus, which can also be found in extrapelvic locations. Although patients seeking treatment for endometriosis usually present to gynecologists, there are rare cases of endometriosis encountered by plastic surgeons in routine practice, either incidentally or as a concomitant finding. Methods: We present a rare case of a 36-year-old woman with symptoms of panniculitis desiring panniculectomy. During surgery, an abdominal mass was excised and confirmed by pathological analysis to be endometriosis. A comprehensive literature review was conducted using the PubMed search engine of the National Institutes of Health to identify cases of endometriosis in plastic surgery. Following screening of the results, 14 articles were included in this analysis that fit the criteria of our search. Results: Of the 14 articles reviewed, cutaneous endometriosis was the most common subtype found in plastic surgery. None of the studies described findings of endometriosis in routine panniculectomies. Several identified endometriosis discovered during cosmetic abdominoplasties. Conclusions: Endometriosis encountered in plastic surgery is a rare but clinically important occurrence, with the cutaneous subtype representing the majority of cases. Endometriosis should always be on the differential diagnosis when an abdominal mass is found in a patient with a history of abdominal surgery. Abdominal masses found during routine aesthetic or reconstructive surgery should be submitted for tissue analysis to guide possible secondary treatments.

Summary: Mucoceles can often present as a complication after prior sinus surgery or maxillofacial trauma when mucosal drainage is obstructed. Their presence in the orbit following orbital wall fracture and subsequent repair represent an exceedingly rare complication whose occurrence is limited to a few reported cases in the literature. In these patients, continuous cyst expansion and subsequent mass effect may lead to ophthalmic symptoms, including orbital pain, proptosis, diplopia, and globe dystopia. We report the discovery of an orbital mucocele after orbital floor fracture repair and its possible association with the nonporous reconstruction plate utilized for fixation. When a patient with history of orbital wall reconstruction presents with new-onset ocular symptoms, an orbital mucocele should be considered as a potential diagnosis.

Background: Topical nitrates have demonstrated efficacy in improving flap perfusion. However, evidence for nontopical nitrates in modulation of flap perfusion dynamics has yet to be consolidated. Here, we review evidence regarding the use of intravascular, sublingual, and oral nitrates in modulating flap perfusion. Methods: We performed a review of the literature for evidence linking nontopical nitrates and flap perfusion, and included clinical studies, animal studies, and in vitro studies. Results: Evidence suggests that intravascular, sublingual, and oral nitrates exert vasodilatory properties, which may be harnessed for identification of perforators and improved flap perfusion. We also found evidence suggesting nitrates may facilitate ischemic preconditioning while reducing ischemia–reperfusion injury. Conclusions: Nitrates delivered intravascularly, sublingually, or orally may increase flap perfusion and serve as a method for ischemic preconditioning, particularly in the intraoperative setting.

Background: Secondary lymphedema (SL) affects 120 million people globally, posing a lifelong burden for up to 37% of cancer survivors. Chronic inflammation and progressive fibrosis are key drivers of SL, yet detailed characterization of immune cell subpopulations across lymphedema stages is lacking. This study aimed to investigate the immunologic profile of lymphedematous skin and its association with extracellular matrix changes, which could serve as clinical biomarkers or therapeutic targets. Methods: This case-control study analyzed the skin from 36 patients with and without SL, using immunofluorescence to quantify T cells, B cells, macrophages, and their subpopulations. Collagen quantity and composition were examined using picrosirius red staining, and mast cell infiltration was assessed with toluidine blue staining. Early and late SL stages were compared to identify histomorphological and immunologic correlates of stage progression. Results: We found a predominance of CD4+ T cells and mast cells in SL skin (1.4/mm² versus 1.0/mm², P < 0.01; 1.2/mm² versus 0.2/mm², P < 0.0001) and a higher ratio of collagen III to collagen I fibers (51.6% versus 75.0%, P < 0.001). M2 macrophages were more abundant in late-stage than in early-stage lymphedema (1.7/mm² versus 1.0/mm², P = 0.02). Conclusions: This study demonstrated a shift toward CD4+ T cell and mast cell infiltration in SL skin, correlating with extracellular matrix disorganization and an altered collagen III/I ratio. These findings enhance our understanding of the cellular and morphological changes in SL, potentially guiding future diagnostic and therapeutic strategies.
背景：继发性淋巴水肿（SL）影响着全球 1.2 亿人，对多达 37% 的癌症幸存者造成终身负担。慢性炎症和进行性纤维化是继发性淋巴水肿的主要驱动因素，但目前还缺乏对淋巴水肿各阶段免疫细胞亚群的详细描述。本研究旨在调查淋巴水肿皮肤的免疫学特征及其与细胞外基质变化的关系，这些变化可作为临床生物标志物或治疗靶点。研究方法这项病例对照研究分析了 36 名淋巴水肿患者和非淋巴水肿患者的皮肤，使用免疫荧光定量检测了 T 细胞、B 细胞、巨噬细胞及其亚群。使用吡啶红染色法检测胶原蛋白的数量和组成，使用甲苯胺蓝染色法评估肥大细胞浸润情况。对早期和晚期 SL 阶段进行比较，以确定阶段进展的组织形态学和免疫学相关因素。结果我们发现在 SL 期皮肤中 CD4+ T 细胞和肥大细胞占优势（1.4/mm² 对 1.0/mm²，P < 0.01；1.2/mm² 对 0.2/mm²，P < 0.0001），胶原 III 纤维对胶原 I 纤维的比例更高（51.6% 对 75.0%，P < 0.001）。晚期淋巴水肿患者的 M2 巨噬细胞比早期淋巴水肿患者更丰富（1.7/mm² 对 1.0/mm²，P = 0.02）。结论本研究表明，淋巴水肿皮肤向 CD4+ T 细胞和肥大细胞浸润转变，这与细胞外基质紊乱和胶原 III/I 比值改变有关。这些发现加深了我们对 SL 细胞和形态学变化的理解，有可能指导未来的诊断和治疗策略。

Background: The maxilla comprises horizontal and vertical buttresses, each with specific functions, supporting various organs, such as the eyes, nose, and oral cavity. Notably, they combine to form a three-dimensional structure, which enables the buttresses to provide their inherent support strength. However, reconstructing the maxilla after maxillectomy by assembling new buttresses is challenging. We successfully reconstructed all the buttresses crucial for facial appearance and dental rehabilitation using a vascularized fibular flap. Methods: Four patients underwent maxillary buttress reconstruction with a fibular flap after total or subtotal maxillectomy. We used computer-aided design/computer-aided manufacturing digital technology to osteotomize the fibula into multiple segments and assemble them to reconstruct the maxillary buttresses. Each buttress was assembled based on a preoperative simulation. Results: All patients underwent immediate one-stage maxillary reconstruction. They had good maxillary buttress alignment and acquired good facial appearance, eye position, nasal airway, and prosthetically suitable maxillary alveolus ridge. Conclusions: The combination of computer-aided design/computer-aided manufacturing digital technology and surgical techniques has enabled novel maxillary reconstruction, providing great hope to patients experiencing facial disfigurement and loss of function after maxillectomy.

Background: Immunotherapy has transformed breast cancer management. However, it can be challenging to remain familiar with the adverse events, contraindications, and perioperative recommendations for each agent. Methods: We used FDALabel to identify all Food and Drug Administration–approved immunotherapies indicated for the treatment of breast cancer. We extracted details regarding warnings and precautions, indications, and adverse events from each package insert. Results: We identified nine immunotherapies belonging to three classes: anti-human epidermal growth factor receptor 2 (HER2) agents, anti-programmed cell death protein 1 (PD-1) agents, and anti-trophoblast cell-surface antigen 2 (TROP-2) agents. Cardiotoxicity, including heart failure and cardiomyopathy, was common among those receiving anti-HER2 agents, and hypothyroidism was common among patients receiving the anti-PD-1 agent. The anti-TROP-2 agent was associated with diarrhea and neutropenia. Given the adverse event profile for each drug, we recommend preoperative evaluation components, including transthoracic echocardiography, liver function tests, and thyroid panels. We also indicate here which immunotherapies raise concern for venous thromboembolism, hematoma, and infection. Conclusions: Using data from clinical trials, we recommend a preoperative evaluation tailored to the immunotherapeutic regimen of individual patients.

However, it can be challenging to remain familiar with the adverse events, contraindications, and perioperative recommendations for each agent. Methods: We used FDALabel to identify all Food and Drug Administration–approved immunotherapies indicated for the treatment of breast cancer. We extracted details regarding warnings and precautions, indications, and adverse events from each package insert. Results: We identified nine immunotherapies belonging to three classes: anti-human epidermal growth factor receptor 2 (HER2) agents, anti-programmed cell death protein 1 (PD-1) agents, and anti-trophoblast cell-surface antigen 2 (TROP-2) agents. Cardiotoxicity, including heart failure and cardiomyopathy, was common among those receiving anti-HER2 agents, and hypothyroidism was common among patients receiving the anti-PD-1 agent. The anti-TROP-2 agent was associated with diarrhea and neutropenia. Given the adverse event profile for each drug, we recommend preoperative evaluation components, including transthoracic echocardiography, liver function tests, and thyroid panels. We also indicate here which immunotherapies raise concern for venous thromboembolism, hematoma, and infection. Conclusions: Using data from clinical trials, we recommend a preoperative evaluation tailored to the immunotherapeutic regimen of individual patients.","PeriodicalId":516238,"journal":{"name":"Plastic & Reconstructive Surgery-Global Open","volume":"16 6","pages":"e5915"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141409627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Summary: Lymphedema following oncologic intervention can cause significant lifelong morbidity for patients in whom conservative management fails. The associated swelling, discomfort, pain, and recurrent cellulitis greatly diminish quality of life. Surgical procedures, including suction-assisted lipectomy, lymphovenous anastomosis (LVA), and vascularized lymph node transfers, show effectiveness in both volume reduction in affected extremities and symptom relief. However, the success of procedures like LVA is dependent on effective preoperative lymphatic mapping to identify suitable vessels for anastomosis. Traditional superficial lymphatic mapping uses near infrared fluorescence indocyanine green (ICG) imaging. Moreover, recent advances in contrast-enhanced ultrasound (CEUS) lymphography increased lymphovenous bypass target identification for LVA in the extremities.7 CEUS lymphography uses microbubbles as a contrast-enhancing agent injected intradermally into the affected extremity with subsequent identification of superficial collecting lymphatic vessels using ultrasound. Although a recent report noted an uptick in severe and critical adverse drug reactions to an ultrasound contrast agent injected intravenously in stress echocardiography, adverse drug reactions associated with ultrasound contrast-enhancing agents in body ultrasound are rare. The safety profile and potential complications from CEUS lymphography in the lymphedema population have yet to be fully characterized. In this case report, the authors present the first cutaneous adverse drug event following a secondary exposure to the contrast used for CEUS imaging. Mechanisms and justifications for an immune-mediated process are explored, and a review of similar manifestations in other related contrast applications is discussed.
