Positive Bacterial Cultures on Spinal Wound Closure Do Not Predict Postoperative Outcomes.

BACKGROUND: Complex surgical back wounds represent significant morbidity in patients who have undergone spinal procedures requiring closure or revision by plastic surgeons. This study aimed to assess the utility of bacterial wound culture data for predicting surgical outcomes of wound management. METHODS: This study is a single-institution retrospective review of consecutive patients who required plastic surgery intervention for wound infection following spinal procedures between the years 2010 and 2021 (n = 70). Statistical analysis was performed for demographics, comorbidities, perioperative laboratory studies, and treatment methods. The primary outcomes of interest were rate of postoperative complications after soft tissue reconstruction and reconstructive failure. The secondary outcome of interest was time to healing in number of days. RESULTS: The overall complication rate after wound closure was 31.4%, with wound infection in 12.9%, seroma in 10%, dehiscence in 12.9%, and hematoma in 1.4%. Increasing number of debridements before wound closure increased the likelihood of a surgical complication of any kind (odds ratio [OR], 1.772; 95% confidence interval [CI], 1.045-3.002). Positive wound cultures before reconstruction were associated with development of seroma only (OR, 0.265; 95% CI, 0.078-0.893). Use of incisional vacuum-assisted closure devices significantly decreased the odds of postoperative wound dehiscence (OR, 0.179; 95% CI, 0.034-0.904) and increased odds of healing (hazard ratio, 3.638; 95% CI, 1.547-8.613). CONCLUSIONS: Positive wound cultures were not significantly associated with negative outcomes after complex closure or reconstruction of infected spinal surgical wounds. This finding emphasizes the importance of clinical judgment with a multidisciplinary approach to complex surgical back wounds over culture data for wound closure timing.

Pregnancy Termination Policy and Cleft Lip and Palate.

BACKGROUND: Restrictive policies on termination of pregnancy (TOP) may lead to more infants with congenital abnormalities. This study aims to assess the association between state-wide enactment of TOP restriction and cleft lip and/or palate (CL/P) incidence and identify mediating demographic characteristics. METHODS: This study examines state-specific trends in CL/P incidence in infants before and after implementing laws restricting TOP in MI compared to NY, where no such laws were passed. The percent change of CL/P incidence per 1000 live births in post-policy years (2012-2015) compared to pre-policy years (2005-2011) was compared while adjusting for confounding factors in multivariate models. RESULTS: The incidence of CL/P changed significantly in MI (19.1%) versus NY (-7.31%). Adjusting for sex, race/ethnicity, median household income level, and expected payer revealed that the adjusted percent difference between MI and NY was 53.3% (p <0.001). Stratification by race/ethnicity and median household income demonstrated that changes were only significant amongst Black (139%, p<0.001) and Hispanic (125%, p=0.045) patients or of those from the lowest (50.3%, p<0.001) and second lowest (40.1%, p=0.01) income quartiles. CONCLUSIONS: Our research, combined with the recent Dobbs Supreme Court decision allowing states to place further restrictions on TOP, suggests that more infants in the future will be born in need of treatment for CL/P.

Parent American Sign Language skills correlate with child-but not toddler-ASL vocabulary size.

Most deaf children have hearing parents who do not know a sign language at birth, and are at risk of limited language input during early childhood. Studying these children as they learn a sign language has revealed that timing of first-language exposure critically shapes language outcomes. But the input deaf children receive in their first language is not only delayed, it is much more variable than most first language learners, as many learn their first language from parents who are themselves new sign language learners. Much of the research on deaf children learning a sign language has considered the role of parent input using broad strokes, categorizing hearing parents as non-native, poor signers, and deaf parents as native, strong signers. In this study, we deconstruct these categories, and examine how variation in sign language skills among hearing parents might affect children's vocabulary acquisition. This study included 44 deaf children between 8- and 60-months-old who were learning ASL and had hearing parents who were also learning ASL. We observed an interactive effect of parent ASL proficiency and age, such that parent ASL proficiency was a significant predictor of child ASL vocabulary size, but not among the infants and toddlers. The proficiency of language models can affect acquisition above and beyond age of acquisition, particularly as children grow. At the same time, the most skilled parents in this sample were not as fluent as "native" deaf signers, and yet their children reliably had age-expected ASL vocabularies.

"Comparison of Outcomes After Autologous Breast Reconstruction: Latissimus Dorsi with Immediate Fat Transfer vs. Abdominally Based Free Flaps".

BACKGROUND: Autologous breast reconstruction confers favorable patient reports of satisfaction and quality of life compared to implant-based reconstruction over a lifetime. The latissimus dorsi with immediate fat transfer (LIFT) is an alternative approach to abdominally based free flaps (Ab-FF), which expands fully autologous reconstruction to non-microsurgeons. This study aims to compare the two procedures concerning their clinical and patient-reported outcomes one year postoperatively. METHODS: We conducted a retrospective review of LIFTs and Ab-FFs performed between March 2017 and August 2022. The primary outcomes were postoperative complications, reoperations, and longitudinal BREAST-Q scores. BREAST-Q modules included Satisfaction with Breasts, Abdomen, Back, Psychosocial Well-being, Physical Well-being: Chest, Abdomen, Back, and Sexual Well-being. RESULTS: Of the 281 included patients (408 breasts), 211 received Ab-FF, and 70 received LIFT. One-year follow-up (median [IQR]: 12 [12] months) demonstrated that Ab-FF independently predicted dehiscence, reoperation procedures, and revisional surgery. LIFT independently increased the odds of seroma. In addition, obesity predicted dehiscence, while bilateral reconstructions predicted revisional fat grafting. BREAST-Q scores fluctuated over time but were similar across all measured domains by one year postoperatively. CONCLUSIONS: Although Ab-FF is the gold-standard approach for fully autologous reconstruction, LIFT procedures may be associated with a less complicated postoperative course while eliciting similar patient-reported outcomes. LIFT may subsequently be preferred to limit postoperative complications, particularly in patients with obesity. LIFT can also be utilized by more plastic surgeons who are either not microsurgically trained or do not have an environment that fosters Ab-FF.

The Effect of Obesity on Vaginoplasty Outcomes.

BACKGROUND: Some surgeons use body mass index criteria within the patient selection processes before vaginoplasty, thereby limiting access to select obese patients. We sought to better characterize the effect of obesity on postoperative outcomes across multiple vaginoplasty techniques. METHODS: A single-center retrospective review of all transfeminine patients undergoing primary vaginoplasty procedures from December 2018 to July 2022 was conducted. Patients were stratified into cohorts according to the World Health Organization Obesity Class criteria. Data regarding demographics, comorbidities, operative details, postoperative complications, and all-cause revision were collected. RESULTS: A total of 237 patients met the inclusion criteria. Average follow-up duration was 9.1 ± 4.7 months. Multivariate regression revealed that patients with class I and class II/III obesity were associated with higher odds of developing vaginal stenosis (class I: odds ratio [OR], 7.1 [ P = 0.003]; class II/III: OR, 3.4 [ P = 0.018]) and all-cause revision (class I: OR, 3.7 [ P = 0.021]; class II/III: OR, 4.8 [ P = 0.027]). Undergoing either robotic peritoneal or robotic intestinal vaginoplasty was associated with lower odds of delayed wound healing (peritoneal: OR, 0.2 [ P < 0.001]; intestinal: OR, 0.2 [ P = 0.011]). Lastly, adherence to dilation regimen was negatively associated with development of vaginal stenosis (OR, 0.04; P < 0.001). CONCLUSIONS: Patients with obesity may be at a higher risk of developing vaginal stenosis after vaginoplasty, which may ultimately necessitate operative revision. Although patients with obesity may remain surgical candidates, proper preoperative counseling and adherence to postoperative vaginal dilation regimens are critical to optimizing outcomes.

A case of necrotizing fasciitis of the breast following lumpectomy and oncoplastic closure.

BACKGROUND: NF is a life-threatening soft tissue infection that most commonly occurs in the lower extremity. While presenting symptoms such as erythema, severe pain, sepsis, and wound crepitation are well documented, diagnosis of NF of the breast often is obscured by a low clinical index of suspicion due to its relative rarity as well as by the breast parenchyma that physically separates the underlying fascia and overlying skin. Several risk factors have previously been identified, such as underlying infection, diabetes, advanced age, and immunosuppression. However, the gross morbidity and high mortality associated with NF warrant continued surveillance of contributing factors across any anatomic location. Fifteen cases in the literature document the development of NF following breast surgery. CASE REPORT: The authors of this case report aim to expand on the current literature through the presentation of a unique case of NF of the breast following right breast lumpectomy and oncoplastic closure with left reduction mammaplasty in an immunocompromised patient found to have concurrent perforated sigmoid diverticulitis. CONCLUSION: This case exemplifies how frequent postoperative surveillance, a low threshold for intervention, and efficient coordination of care are vital to minimizing the morbidity and mortality risks associated with NF of the breast.

Surgical techniques and outcomes of thyroid chondroplasty in transfeminine individuals: A systematic review.

Thyroid chondroplasty (TC) in facial gender-affirming surgery (FGAS) is aimed at modifying the thyroid cartilage to achieve a more feminine laryngeal appearance. This study evaluated open versus endoscopic techniques to TC and associated outcomes and complications. A systematic review (SR) of articles pertaining to TC was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twelve articles representing 368 patients were included for analysis. Nine articles described open approaches, and three articles described endoscopic techniques. The rate of total complications was 4.3% (n = 12) in the open approach compared to 15% (n = 13) in the endoscopic approach. Positive esthetic results were reported in 92% of cases performed with the open approach and 90% with the endoscopic approach. In the open approach, seven (2.5%) patients requested additional removal of cartilage, and three (1.1%) requested scar revision. In the endoscopic approach, three (3.7%) patients requested additional cartilage removal. In addition, data of individuals who underwent "cervical tracheoplasty" for gender dysphoria from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was reviewed, and there was no incidence of wound or major complications among patients who underwent tracheoplasty alone. Although the advantage of the endoscopic approach is a scarless neck incision, the rate of complications is higher with the open approach. Endoscopic approaches are still not widely used, and continued investigations are warranted to improve familiarity with this approach and reduce postoperative complications.

Age is just a number: The role of advanced age in predicting complications following ventral hernia repair with component separation.

BACKGROUND: While advanced age is often considered a risk factor for complications following abdominal surgery, its impact on outcomes after complex open ventral hernia repair (VHR) with component separation technique (CST) remains unclear. METHODS: A single-center retrospective review of patients who VHR with CST from November 2008 to January 2022 was performed and cohorts were stratified by presence of advanced age (≥60 years). RESULTS: Of 219 patients who underwent VHR with CST, 114 patients (52.1 â€‹%) were aged ≥60 years. Multivariate analysis demonstrated BMI to be an independent predictor for any complication (OR 1.1, p â€‹= â€‹0.002) and COPD was positively associated with seroma development (OR 20.1, p â€‹= â€‹0.012). Advanced age did not independently predict postoperative outcomes, including hernia recurrence (OR 0.8, p â€‹= â€‹0.766). CONCLUSIONS: VHR with CST is generally safe to perform in patients of advanced age. Every patient's comorbidity profile should be thoroughly assessed preoperatively for risk stratification regardless of age.

Free Tissue Transfer to the Lower Extremity in the Setting of Thrombocytosis and the Role of Antiplatelet Therapy: A Propensity Score-Matched Analysis.

BACKGROUND: Free tissue transfer (FTT) provides a versatile method to achieve successful lower limb salvage. Thrombocytosis in patients undergoing lower extremity (LE) FTT is associated with increased risk of complications. The aims of this study were to assess the feasibility of performing LE FTT in patients with preoperative thrombocytosis, and whether antiplatelet (AP) therapy on the day of surgery (DOS) affects outcomes. METHODS: A retrospective review of thrombocytotic patients who underwent LE FTT between 2011 and 2022 was performed. Patients were stratified into groups based on the receipt of AP therapy on the DOS. Patients were propensity score matched for comorbidity burden and postoperative risk stratification. Outcomes of interest included perioperative transfusion requirements, postoperative flap-related complications, rates of flap success, limb salvage, and ambulatory status. RESULTS: Of the 279 patients who underwent LE FTT, 65 (23.3%) were found to have preoperative thrombocytosis. Fifty-three patients remained following propensity score matching; of which, 32 (60.4%) received AP therapy on the DOS and 21 (39.6%) did not. Overall flap success rate was 96.2% (n = 51). The likelihoods of thrombosis and hematoma development were similar between cohorts (p = 0.949 and 0.574, respectively). Receipt of DOS AP therapy was associated an additional 2.77 units and 990.10 mL of transfused blood (p = 0.020 and 0.018, respectively). At a mean follow-up of 20.7 months, overall limb salvage and ambulatory rates were 81.1% (n = 43) and 79.2% (n = 42), respectively, with no differences between cohorts. CONCLUSION: Preoperative thrombocytosis is not an absolute contraindication to LE FTT. DOS AP therapy may be protective in comorbid patients with elevated platelet counts but must be weighed against possible short-term bleeding as suggested by significant increases in postoperative transfusion requirements.

Postoperative Glycemic Response in High-Risk Type II Diabetics Receiving Below-Knee Amputation: Does Intraoperative Dexamethasone Make an Impact?

Despite known risks of hyperglycemia on postoperative complications, the influence of intraoperative dexamethasone on blood glucose has yet to be evaluated within the diabetic limb salvage population. This study aimed to assess the effect of intraoperative dexamethasone on postoperative blood glucose in diabetic patients undergoing atraumatic major lower extremity amputations. A single-center retrospective review of diabetic patients undergoing below-knee amputation between January 2017 and December 2022 was performed. Blood glucose levels for the 5 days before and after amputation were recorded and compared with the primary endpoints of postoperative hyperglycemia (>200 mg/dL) and glucose variability (>200 mg/dL). Cohorts were divided by patients who did and did not receive intraoperative administration of dexamethasone. Three hundred eighty-one were screened for eligibility with 180 patients included. Of these, 50 patients received dexamethasone intraoperatively (38.5%). Average pre- and postoperative blood glucose, rate of pre- and postoperative hyperglycemia, perioperative glucose variability, and postoperative dehiscence and infection were comparable between cohorts. On multivariate analysis, intraoperative administration of dexamethasone was not associated with postoperative hyperglycemia (p = .104) or perioperative blood glucose variability > 200 mg/dL (p = .334). Perioperative blood glucose variability > 200 mg/dL was associated with higher odds of surgical site infection (SSI) (odds ratio 5.12, p = .003). Administration of intravenous dexamethasone to diabetic patients undergoing below-knee amputation is not associated with postoperative hyperglycemia or complications. This study confirms previous findings that high glucose is a predictor of SSI. Concerted effort by a multidisciplinary team to attain tight glycemic control is critical to optimizing healing.

Seeing things the same way: perspectives and lessons learned from research-design collaborations.

Information visualizations are increasingly being developed by informatics researchers to communicate health information to lay audiences. For high-quality results, it is advisable to collaborate with creative professionals such as graphic designers, illustrators, or user interface/user experience designers. However, such collaborations are often a novel experience for both parties, each of which may be unfamiliar with the needs and processes of the other. We have coalesced our experiences from both the research and design perspectives to offer practical guidance in hopes of promoting the success of future collaborations. We offer suggestions for determining design needs, communicating with design professionals, and carrying out the design process. We assert that successful collaborations are predicated on careful and intentional planning at the outset of a project, a thorough understanding of each party's scope expertise, clear communication, and ample time for the design process to unfold.

To Mesh or Not to Mesh: What Is the Ideal Meshing Ratio for Split Thickness Skin Grafting of the Lower Extremity?

Split-thickness skin grafts can provide effective autologous wound closure in patients with dysvascular comorbidities. Meshing the graft allows for reduced donor site morbidity and expanded coverage. This study directly compares outcomes across varying meshing ratios used to treat chronic lower extremity wounds. Patients who received split-thickness skin grafts to their lower extremity for chronic ulcers from December 2014 to December 2019 at a single center were retrospectively reviewed. Patients were stratified by meshing ratios: nonmeshed (including pie crusting), 1.5:1, and 3:1. The primary outcome was clinical "healing" as determined by surgeon discretion at 30 days, 60 days, and the latest follow-up. Secondary outcomes included postoperative complications, graft loss, ulcer recurrence, progression to amputation, and mortality. A total of 321 patients were identified. Wound sizes and location differed significantly, with 3:1 meshing applied to the largest wounds (187.8 ± 157.6 cm2; 1.5:1 meshed, 110.4 ± 103.9 cm2; nonmeshed 38.7 ± 55.5 cm2; p < .0001) mostly of the lower leg (n = 18, 75%; 1.5:1 meshed, n = 23, 43.4%; nonmeshed n = 62, 25.7%; p < .0001). Meshed grafts displayed a significantly higher proportion of healing at 30 and 60 days, but no differences persisted by the final follow-up (16.5 ± 20.5 months). Longitudinally, nonmeshed STSG was associated with most graft loss (46, 19.1%; p = .011) and ulcer recurrence (44, 18.3%; p = .011). Of the 3 meshing ratios, 3:1 exhibited the lowest rates of complications. Our results suggest that 3:1 meshing is a safe option for coverage of large lower extremity wounds to minimize donor site morbidity.

Lymphovenous Coupler-Assisted Bypass for Immediate Lymphatic Reconstruction.

BACKGROUND: Breast cancer-related lymphedema is the most common cause of lymphedema in the United States and occurs in up to 50% of individuals receiving axillary lymph node dissection (ALND). Lymphovenous bypass (LVB) at the time of ALND may prevent lymphedema, but long-term results and anastomotic patency are unclear. This study evaluates the feasibility and outcomes of performing immediate lymphatic reconstruction via coupler-assisted bypass (CAB). METHODS: This is a retrospective review of all patients undergoing prophylactic LVB following ALND at two tertiary care centers between 2018 and 2022. Patients were divided into cohorts based on whether they received the "standard" end-to-end (E-E) suturing or CAB technique. The primary outcome of interest was development of lymphedema. Quantitative and qualitative assessments for lymphedema were performed preoperatively and at 3, 6, 12, and 24 months postoperatively. RESULTS: Overall, 63 LVBs were performed, of which 24 lymphatics underwent immediate reconstruction via "CAB" and 39 lymphatics via "standard" end-to-end suture. Patient characteristics, including body mass index, and treatment characteristics, including radiation therapy, did not significantly differ between groups. CAB was associated with a greater mean number of lymphatics bypassed per vein (standard 1.7 vs. CAB 2.6, p = 0.0001) and bypass to larger veins (standard 1.2 vs. CAB 2.2 mm, p < 0.0001). At a median follow-up of 14.7 months, 9.1% (1/11) of individuals receiving CAB developed lymphedema. These rates were similar to those seen following standard bypass at 4.8% (1/21), although within a significantly shorter follow-up duration (standard 7.8 vs. CAB 14.7 months, p = 0.0170). CONCLUSION: The CAB technique is a viable, effective technical alternative to the standard LVB technique. This comparative study of techniques in prophylactic LVB suggests that CABs maintain long-term patency, possibly due to the ease of anastomosing several lymphatics to single large caliber veins while reducing the technical demands of the procedure.

Muscle versus Fascia Free Tissue Transfer for Treatment of Chronic Osteomyelitis in the Comorbid Population.

BACKGROUND: In patients with chronic lower extremity (LE) wounds, chronic osteomyelitis confers additional complexity to achieving adequate treatment. Previous reviews demonstrate increased rates of osteomyelitis recurrence in patients who receive muscle flaps compared with fasciocutaneous flaps for LE limb salvage; however, these studies were not limited to atraumatic populations who receive exclusively free flaps. Thus, this study compared rates of recurrence in chronic osteomyelitis patients undergoing LE reconstruction with fasciocutaneous versus muscle free flaps. METHODS: Patients undergoing free tissue transfer (FTT) between July 2011 and July 2021 were retrospectively reviewed. Patients were stratified into fasciocutaneous and muscle free flap groups. Primary outcomes included osteomyelitis recurrence, flap complications, limb salvage, and ambulatory status. RESULTS: Forty-eight patients with pathologic diagnosis of chronic osteomyelitis of the wound bed were identified, of which 58.3% received fasciocutaneous (n = 28) and 41.7% received muscle flaps (n = 20). The most common comorbidities included diabetes mellitus (n = 29, 60.4%), peripheral neuropathy (n = 27, 56.3%) and peripheral vascular disease (n = 24, 50.0%). Methicillin-resistant or methicillin -sensitive Staphylococcus aureus were the most common pathogen in 18.7% (n = 9) of procedures. The majority of patients underwent a median of three debridements followed by negative pressure wound therapy prior to receiving FTT. At a median follow-up of 16.6 months, the limb salvage and ambulatory rates were 79.2 (n = 38) and 83.3% (n = 40), respectively. The overall rate of microsurgical flap success was 93.8% (n = 45). Osteomyelitis recurred in 25% of patients (n = 12) at a median duration of 4.0 months. There were no significant differences in rates of osteomyelitis recurrence, flap complications, limb salvage, ambulation, and mortality. On multivariate analysis, flap composition remained a nonsignificant predictor of osteomyelitis recurrence (odds ratio: 0.975, p = 0.973). CONCLUSION: This study demonstrates that flap composition may not influence recurrence of osteomyelitis following free flap reconstruction of chronic LE wounds, suggesting that optimal flap selection should be based on wound characteristics and patient goals.

Surgical management of pain or infection secondary to calciphylaxis: a wound center's experience and algorithmic multidisciplinary approach.

BACKGROUND: The role of surgical management of calciphylaxis remains understudied. OBJECTIVE: This article reports a case series and algorithmic approach to the multidisciplinary management of calciphylaxis. METHODS: A single-center retrospective review of all adult patients with calciphylaxis treated surgically between January 2010 and November 2022 was performed. RESULTS: Eleven patients met inclusion criteria. The average age was 50.9 years ± 15.8 SD, and most patients were female (n = 7 [63.6%]). Surgery was indicated for infection (n = 6 [54.5%]) and/or intractable pain (n = 11 [100%]). Patients underwent an average of 2.9 excisional debridements during their hospital course. Following the final excision, wounds were left open in 5 cases (29.4%), closed primarily in 4 (23.5%), and local flaps were used in 3 (27.3%). Postoperatively, the mean time to healing was 57.4 days ± 12.6. Complications included dehiscence (n = 1 [9.1%]), progression to cellulitis (n = 2 [18.2%]), osteomyelitis (n = 1 [9.1%]), and lower extremity amputation (n = 2 [18.2%]). Of the 6 patients alive at the time of healing, 5 (83.3%) were no longer taking narcotic medications. At an average follow-up of 26.4 months ± 34.1, 7 patients (63.6%) were deceased, with an average time to mortality of 4.8 months ± 6.7. Of the 4 remaining patients, 3 (75.0%) were ambulatory by their most recent follow-up visit. CONCLUSION: While the morbidity and mortality associated with calciphylaxis are substantial, surgical excision is effective in reducing pain and improving quality of life in patients with this end-stage disease. Wound care centers are uniquely equipped with a variety of medical and surgical specialists with experience in treating chronic wounds and thus facilitate an efficient multidisciplinary model.

Implications of Single-Vessel Runoff on Long-Term Outcomes of Free Tissue Transfer for Lower Extremity Reconstruction.

BACKGROUND: Patients with complex lower extremity (LE) wounds and single-vessel LE runoff (1-VRO) are often considered for amputation. While more challenging, free tissue transfer (FTT) is a means for limb salvage. This study aims to demonstrate the feasibility of limb salvage with FTT in patients with 1-VRO. METHODS: Patients undergoing FTT by a single surgeon between 2011 and 2021 were retrospectively reviewed. Data collected included demographics, wound characteristics, vascular status, and operative details. Patients were divided into cohorts based on 1- versus 3-VRO of tibial vessel inflow. Outcomes of interest included postoperative complications such as flap necrosis, flap success, limb salvage, and ambulatory status. RESULTS: A total of 188 patients underwent FTT to LE, with 25 patients (13.3%) having 1-VRO. Patients with 1-VRO had a comparable prevalence of diabetes (56.0% vs. 50.0%, p = 0.569) and end-stage renal disease (8.0% vs. 3.7%, p = 0.319). Osteomyelitis was more common in the 1-VRO group (80.0% vs. 60.1%, p = 0.056). FTT donor sites and flap composition were similar between cohorts. At mean follow-up of 21.2 months (interquartile range 24.5:5.6, 30.1 months), limb salvage rates were similar between cohorts (84.0% vs. 91.4%, p = 0.241), with no significant differences in ambulatory status or mortality. Higher complication rates occurred in the 1-VRO cohort (48.0% vs. 21.5%, p = 0.004), of which partial flap necrosis was more prevalent in the 1-VRO group (8.0% vs. 1.2%, p = 0.029). There was no difference in flap success rates between groups (p = 0.805). More postflap angiograms were performed in the 1-VRO group (32.0% vs. 9.2%, p = 0.001), but there was no difference in need for repeat percutaneous endovascular intervention between groups. CONCLUSION: This study demonstrates that FTT reconstruction to the LE remains a reliable reconstruction option for limb salvage in patients with single-vessel supply to the LE. Reliance on advanced perioperative management and patient optimization is effective at reducing negative outcomes.

Clinical Efficacy of Topical Vitamin C on the Appearance of Wrinkles: A Systematic Literature Review.

PURPOSE: A rise in market demand for anti-aging skin care products has resulted in a proliferation of cosmeceuticals, including products that contain vitamin C. Many topicals containing vitamin C claim to reduce the appearance of wrinkles. However, these claims have not been systematically evaluated. METHODS: A systematic review of literature published between January 2015 and September 2022 was performed per PRISMA guidelines. Scopus, Web of Science, and PubMed were queried for records relevant using the following Medical Subject Heading (MeSH) terms: “Topical Vitamin C OR Ascorbic acid”, “Vitamin C efficacy”, “dermatology”, “cosmetology”, and “skin anti-aging”. Variables of interest included: study type, study location, study duration, sample size, patient description, type and ingredients of the topical formulation, outcome measurement, results, and adverse events. RESULTS: After deduplication, consideration of inclusion and exclusion criteria, and title/abstract screening, 5,428 initial records were reduced to 7 articles, including 4 meeting Level IB criteria, one meeting Level IIA criteria, and 2 meeting Level IIB criteria. Methods for assessing clinical improvements included global photodamage score, skin topography assessment, reflectance confocal microscopy (RCM) skin analysis, Dynamical Atlas, and participant self-assessment.  Conclusions: While 4 of the 7 studies met Level IB evidence, further high-quality, prospective, and comparative studies are indicated to better elucidate the role of topical vitamin C in wrinkle reduction. All the studies used vitamin C in combination with other ingredients or therapeutic mechanisms, thereby complicating any specific conclusions regarding the efficacy of vitamin C. Citation: Sanabria B, Berger LE, Mohd H, et al. Clinical efficacy of topical vitamin C on the appearance of wrinkles: a systematic literature review. J Drugs Dermatol. 2023;22(9):898-904. doi:10.36849/JDD.7332.

Retrospective review of complications and outcomes in COVID-19-positive patients with comorbidities undergoing limb salvage procedures in a tertiary care wound center.

INTRODUCTION: COVID-19 illness is associated with increased operative risks, ranging from delayed wound healing and coagulopathy to increased risk of mortality. OBJECTIVE: This article describes the authors' recent experience of the implications of COVID-19 on limb salvage procedures. MATERIALS AND METHODS: Patients who underwent LE limb salvage procedures within 30 days of a positive COVID-19 diagnosis were retrospectively reviewed. Patient demographics, comorbidities, surgical factors, postoperative complications, and management were collected. RESULTS: Of 597 patients screened from February 2020 to March 2022, a total of 67 (11.2%) were diagnosed with COVID-19, of which 17 received the diagnosis within 30 days of surgery and were thus included. Average follow-up was 43 ± 3.2 months, at which point 6 (35.3%) were fully healed. The mortality rate at the most recent follow-up visit was 29.4% of patients (n = 5). Two patients required admission to the SICU following index procedure, and 1 necessitated a return to the operating room. CONCLUSION: COVID-19 may negatively affect the wound healing process while increasing the mortality rate amongst patients with multiple or severe comorbidities undergoing limb salvage procedures. Medical providers need to be aware of the complexity of these patients and apply a multi-disciplinary protocol to obtain successful outcomes.
