ABSTRACT
BACKGROUND: Hyaluronidase is used as a reversal agent for hyaluronic acid fillers and to increase the diffusion of other medications after infiltration. Cases of hyaluronidase allergy have been described in the literature since 1984. However, it is still frequently misdiagnosed. This review aims to summarize the current literature to describe the clinical picture of hyaluronidase allergy and identify any risk factors associated with its development, as well as provide recommendations for management in plastic surgery. METHODS: A digital search of PubMed, Scopus, and Embase databases was performed by two reviewers following the PRISMA guidelines. This search identified 247 articles. RESULTS: Two hundred forty-seven articles were identified, and 37 of them met the eligibility criteria. One hundred six patients with a mean age of 54.2 years were included in these studies. History of allergy to other substances (timothy grass, egg white, horse serum, penicillin, insect bites, wasp venom, thimerosal, potassium, histamine, phenylmercuric acetate, and nickel) and allergic diseases (asthma, dermatitis, atopy, rhinitis) was reported. A large portion of the patients with a history of repeated exposure (2-4) experienced the symptoms with their second injection. Nonetheless, there was no significant association between time to allergy development and the number of exposures (P = 0.3). Treatment with steroids +/- antihistamines resulted in the rapid and predominantly complete reversal of the symptoms. CONCLUSIONS: Prior injections or sensitization by insect/wasp venom might be the primary factor associated with hyaluronidase allergy development. The time between the repeated injections is not a likely contributor to the presentation. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Photodamage is caused by chronic sun exposure and ultraviolet radiation and presents as wrinkles, sagging, and pigmented spots. An increase in the ultraviolet index can increase a person's perceived age by worsening skin photodamage. However, since the ultraviolet index varies considerably between geographical regions, perceived age might vary substantially among them. This review aims to describe the differences in chronological and perceived age in regions of the world with different ultraviolet indexes. A literature search of three databases was conducted for studies analyzing perceived age and its relationship to sun exposure. Ultraviolet indexes from the included studies were retrieved from the National Weather Service and the Tropospheric Emission Monitoring Internet Service. Out of 104 studies, seven fulfilled the inclusion criteria. Overall, 3,352 patients were evaluated for perceived age. All studies found that patients with the highest daily sun exposures had the highest perceived ages for their chronological age ( p < 0.05). People with high sun exposure behaviors living in regions with high ultraviolet indexes will look significantly older than same-aged peers living in lower ultraviolet index regions.
ABSTRACT
ABSTRACT: In patients with breast hypertrophy, excessive breast weight applies pressure on the thorax, which may disrupt the normal breathing. The purpose of this study is to evaluate the impact of the breast hypertrophy and reduction mammoplasty on respiratory function. A comprehensive search of 3 databases, PubMed, Ovid, and Scopus databases, was performed. "Mammoplasty" and "respiration or pulmonary function tests" were the keywords used to search for relevant articles. Ten studies involving 280 patients with breast hypertrophy were included in the final review. Seven articles demonstrated an increase in at least 1 pulmonary function test value after the surgery. This systematic review revealed that, preoperatively, pulmonary function test values of the patients are usually in the normal range. Nonetheless, reduction mammoplasty still improves lung function parameters. Additionally, patients with respiratory complaints felt improvement in their symptoms after the surgery. However, future studies are needed, as heterogeneity among studies was observed.

BACKGROUND: In recent years, magnetic resonance imaging lymphangiography (MRL) has emerged as a way to predict if patients are candidates for lymphedema surgery, particularly lymphovenous anastomosis (LVA). Our goal was to conduct a systematic review of the literature on the use of MRL for preoperative planning in lymphedema surgery. We hypothesized that MRL could add valuable information to the standard preoperative evaluation of lymphedema patients. METHODS: On February 17, 2020, we conducted a systematic review of the PubMed/MEDLINE, Cochrane Clinical Answers, and Embase databases, without time frame or language limitations, to identify articles on the use of MRL for preoperative planning of lymphedema surgery. We excluded studies that investigated other applications of magnetic resonance imaging, such as lymphedema diagnosis and treatment evaluation. The primary outcome was the examination capacity to identify lymphatic anatomy and the secondary outcome was the presence of adverse effects. RESULTS: Of 372 potential articles identified with the search, nine studies fulfilled the eligibility criteria. A total of 334 lymphedema patients were enrolled in these studies. Two studies compared MRL findings with those of other standard examinations (indocyanine green lymphography [ICG-L] or lymphoscintigraphy). No adverse effects due to MRL were reported. A study shown that MRL had higher sensitivity to detect lymphatic vessel abnormalities compared with lymphoscintigraphy and a statistically higher chance of successful LVA was observed when the results of MRL agreed with those of ICG-L (p < .001). CONCLUSIONS: MRL could be useful for preoperative planning in lymphedema surgery. The scientific evidence has been limited, so further studies with greater numbers of patients and cost analysis are necessary to justify the addition of MRL to current preoperative protocols.

The number of applications for facial recognition technology is increasing due to the improvement in image quality, artificial intelligence, and computer processing power that has occurred during the last decades. Algorithms can be used to convert facial anthropometric landmarks into a computer representation, which can be used to help identify nonverbal information about an individual's health status. This article discusses the potential ways a facial recognition tool can perform a health assessment. Because facial attributes may be considered biometric data, clinicians should be informed about the clinical, ethical, and legal issues associated with its use.

Pyoderma gangrenosum is a neutrophilic dermatosis characterized by immune dysfunction and pathergy. Thus, it is frequently seen in patients with underlying systemic illnesses or postoperatively. For the performance of the debridement or closure of the resultant defect, plastic surgeons are often involved in the care of pyoderma patients. However, both procedures may exacerbate the injury. Therefore, plastic surgeons must be familiar with the presentation of postsurgical pyoderma to avoid further damage and safely repair related soft tissue defects. A systematic search of the PubMed/Medline database was performed using the following keywords: "pyoderma gangrenosum" and "surgery." This online database search has identified 656 studies published between 1958 and 2022. Only reconstructed cases of postsurgical pyoderma gangrenosum were selected. Twenty-eight patients who developed pyoderma after dermatologic, plastic, orthopedic, cardiovascular, general, or obstetric surgery were included in this study. The average time to the PG presentation and diagnosis was 5.5 and 17 days, respectively. Diagnostic scoring tools were not used, and the diagnosis was primarily based on histopathology after repeated treatment failures. The patients received split- or full-thickness skin grafts, local, pedicled, and free flaps. An estimated 82.1% underwent skin grafting, whereas 42.9% underwent flap reconstruction. In addition, 21.4% got both the graft and flap. Accurate diagnosis of PSPG, prevention of further surgical injury, and timely medical management are vital for improving patient outcomes. Reconstruction can be performed, if required. However, despite the availability of different reconstructive techniques, there is no standard approach to the management of the PSPG.
ABSTRACT
Necrotizing fasciitis is a severe, life-threatening soft tissue infection that presents as a surgical emergency. It is characterized by a rapid progression of inflammation leading to extensive tissue necrosis and destruction. Nonetheless, the diagnosis might be missed or delayed due to variable and nonspecific clinical presentation, contributing to high mortality rates. Therefore, early diagnosis and prompt, aggressive medical and surgical treatment are paramount. In this review, we highlight the defining characteristics, pathophysiology, diagnostic modalities, current principles of treatment, and evolving management strategies of necrotizing fasciitis.
ABSTRACT
Background: For patients with transfemoral amputations and difficulty tolerating conventional socket-based prostheses, osseointegrated (OI) implants have enabled increased prosthetic use, improved patient satisfaction, and shown promising functional outcomes1,2. Although the use of OI implants effectively eliminates the soft-tissue-related challenges that have plagued socket-based prostheses, the presence of a permanent, percutaneous implant imparts a host of new soft-tissue challenges that have yet to be fully defined. In patients undergoing OI surgery who have redundant soft tissue, we perform a thighplasty to globally reduce excess skin and fat, tighten the soft-tissue envelope, and improve the contour of the residual limb. Description: First, the orthopaedic surgical team prepares the residual femur for implantation of the OI device. After the implant is inserted, the residual hamstrings and quadriceps musculature are closed over the end of the femur, and the subcutaneous tissue and skin are closed in a layered fashion. Although the anatomic location and amount of excess soft tissue are patient-dependent, we perform a standard pinch test to determine the amount of soft tissue that can be safely removed for the thighplasty. Once the proposed area of resection is marked, we proceed with longitudinal, sharp dissection down to the level of the muscular fascia. At this point, we use another pinch test to confirm the amount of soft-tissue resection that will allow for adequate resection without undue tension3. Excess subcutaneous fat and skin are carefully removed along the previously marked incisions, typically overlying the medial compartment of the thigh in the setting of patients with transfemoral amputations. The thighplasty incision is closed in a layered fashion over 1 or 2 Jackson-Pratt drains, depending on the amount of resection. Alternatives: Depending on the amount of redundant soft tissue, thighplasty may not be necessary at the time of OI surgery; however, in our experience, excess soft tissue surrounding the transcutaneous aperture can predispose the patient to increased shear forces at the aperture, increased drainage, and increased risk of infection4. Rationale: Although superficial infectious complications are most common following OI surgery, the need for soft-tissue refashioning and excision is one of the most common reasons for reoperation1,5. Our group has been more aggressive than most in our use of a vertical thighplasty procedure to globally reduce soft-tissue motion in the residual limb to avoid reoperation. Expected Outcomes: Although much of the OI literature has focused on infectious complications, recent studies have demonstrated reoperation rates of 18% to 36% for redundant soft tissue following OI surgery1,5. We believe that thighplasty at the time of OI not only reduces the likelihood of reoperation but may also decrease infectious complications by reducing relative motion and inflammation at the skin-implant interface4,6. Important Tips: The thighplasty procedure is ideally performed as part of the first stage of the OPRA (Osseointegrated Prosthesis for the Rehabilitation of Amputees) procedure to limit the likelihood of problematic ischemia-related complications.We utilize a confirmatory pinch test both before and throughout the thighplasty procedure to ensure adequate resection without undue tension.The thighplasty excision pattern utilizes a long vertical limb designed to decrease the circumferential laxity of the residual limb. Maximal tension is borne on the vertical limb and not on the transverse extensions, as these are prone to scar widening and distortion of surrounding tissues.Closed-suction drainage is utilized liberally to decrease the likelihood of a symptomatic seroma.

ABSTRACT
Background: This study aimed to evaluate the epidemiology of septic shock (SS) associated with intraabdominal infections (IAI) as well as associated mortality and efficacy of early source control in a tertiary-care educational hospital. Methods: Patients who had SS with IAI and consulted by Infectious Diseases consultants between December 2013 and October 2022 during night shifts in our centre were analyzed retrospectively. Results: A total number of 390 patients were included. Overall, 30-day mortality was 42.5% on day 3, while day 14 and 30 mortality rates were 63.3% and 71.3%, respectively. Source control by surgical or percutaneous operation was performed in 123 of 390 cases (31.5%), and the mortality rate was significantly lower in cases that were performed source control at any time during SS (65/123-52.8% vs 213/267-79.8%, p<0.001). In 44 of 123 cases (35.7%), source control was performed during the first 12 hours, and mortality was significantly lower in this group versus others (24/44-54.5% vs 254/346-73.4%, p=0.009). On the other hand, female gender (p<0.001, odds ratio(OR)= 2.943, 95%CI=1.714-5.054), diabetes mellitus (p= 0.014, OR=2.284, 95%CI=1.179-4.424), carbapenem-resistant Gram-negative etiology (p=0.011, OR=4.386, 95%CI=1.398-13.759), SOFA≥10 (p<0.001, OR=3.036, 95%CI=1.802-5.114), lactate >3 mg/dl (p<0.001, OR=2.764, 95%CI=1.562-4.891) and lack of source control (p=0.001, OR=2.796, 95%CI=1.523-5.133) were significantly associated with 30-day mortality in logistic regression analysis. Conclusion: Source control has a vital importance in terms of mortality rates for IAI-related septic shock patients. Our study underscores the need for additional research, as the present analysis indicates that early source control does not manifest as a protective factor in logistic regression.
ABSTRACT
Multiple techniques have been proposed for columellar reconstruction. However, in our patients with philtrum scars, none of them were promising a satisfactory outcome in one stage. Therefore, to achieve the best results in a single-stage surgery, we used a modification of the philtrum flap to repair the columella, named the Kalender (fasciocutaneous philtrum island) flap. Nine patients were operated on using this technique. The male-to-female ratio was 2:1, with a mean age of 22. The mean follow-up period was 12 months. Patient satisfaction and postoperative complications were assessed postoperatively and at all follow-ups using a five-point Likert scale. In addition, patients were satisfied with the aesthetic outcome with a mean score of 4.4. We did not observe any complications. Our experience shows that this method is a safe and technically simple alternative for columellar reconstruction in a select group of patients with philtrum scars.
ABSTRACT
PURPOSE: Breast cancer-related lymphedema (BCRL) has been widely reported in the medical literature. Various patient characteristics, including age, have been investigated as possible risk factors for this disease entity, but the existence and direction of the cause-and-effect relationship are still unclear. In this review, we aimed to evaluate the effect of age on development of BRCL. METHODS: PubMed, Scopus, and Ovid MEDLINE were searched for relevant articles, which were found to be published between 1974 and 2020. RESULTS: Twenty-six studies involving 19,396 patients were selected. The average age of patients was 54.9. 26 studies were included in the final analysis, and 13 articles reported no association between age and BCRL development. CONCLUSIONS: Though studies presented different findings, the majority did not identify age as a risk factor for development of lymphedema. However, the level of evidence of individual studies was low. In this article, we call attention to the need for uniform design of lymphedema studies and diagnosis. IMPLICATIONS FOR CANCER SURVIVORS: All patients should be informed and screened regularly for lymphedema during and after the treatment independent of their age.

Women are less likely to be senior authors, invited to write in scientific journals, and to be cited in high impact journals. The aim of this study was to investigate trends in authorship and gender differences in peer-reviewed burn literature over 13 years. We performed a retrospective analysis of original research articles published from January 2009 to September 2021 in three burn journals. A gender determination application was used to categorize the gender of the first and senior author. Of the 3908 articles analyzed, 42.5% had a woman first author and 27.6% had a woman senior author. We identified 2029 unique senior authors, 29.0% of whom were women. Woman senior authorship was associated with increased odds of woman first authorship [OR = 2.31 (95% CI: 2.00, 2.67); P < .001]. The percentage of papers with a woman senior author increased from 17.8% in 2009 to 35.7% in 2021. If this 1.0% (95% CI: 0.50-1.51%) linear trend increase per year in woman senior authorship continues, we will expect to see equal proportions of woman and man senior authors in the included journals starting in 2037. The field of burn care is far from reaching gender parity with respect to authorship of peer-reviewed publications. Supporting and encouraging gender-concordant and discordant first:last authorship dyads in mentorship as well as redistributing obligations that may detract from authorship opportunities are potential ways to improve parity in authorship and academia.

BACKGROUND: Wearable devices and sensor technology provide objective, unbiased range of motion measurements that help health care professionals overcome the hindrances of protractor-based goniometry. This review aims to analyze the accuracy of existing wearable sensor technologies for hand range of motion measurement and identify the most accurate one. METHODS: We performed a systematic review by searching PubMed, CINAHL, and Embase for studies evaluating wearable sensor technology in hand range of motion assessment. Keywords used for the inquiry were related to wearable devices and hand goniometry. RESULTS: Of the 71 studies, 11 met the inclusion criteria. Ten studies evaluated gloves and 1 evaluated a wristband. The most common types of sensors used were bend sensors, followed by inertial sensors, Hall effect sensors, and magnetometers. Most studies compared wearable devices with manual goniometry, achieving optimal accuracy. Although most of the devices reached adequate levels of measurement error, accuracy evaluation in the reviewed studies might be subject to bias owing to the use of poorly reliable measurement techniques for comparison of the devices. CONCLUSION: Gloves using inertial sensors were the most accurate. Future studies should use different comparison techniques, such as infrared camera-based goniometry or virtual motion tracking, to evaluate the performance of wearable devices.

Unnecessary ED visits and transfers to hand clinics raise treatment costs and patient burden at trauma centers. In the present COVID-19 pandemic, needless transfers can increase patients' risk of viral exposure. Therefore, this review analyzes different aspects of the remote diagnosis and triage of traumatic hand injuries. The most common file was photography, with the most common devices being cell phone cameras. Treatment, triage, diagnosis, cost, and time outcomes were assessed, showing concordance between teleconsultation and face-to-face patient evaluations. We conclude that photography and video consultations are feasible surrogates for ED visits in patients with traumatic hand injuries. These technologies should be leveraged to decrease treatment costs and potentially decrease the time to definitive treatment after initial evaluation.
ABSTRACT
INTRODUCTION: With the increasing number of breast cancer survivors and reconstruction operations, persistent pain following breast cancer surgery (PPBCT) and its management is becoming a challenge for plastic surgeons. To date, most studies compared the difference in the level of PPBCT in reconstruction versus nonreconstruction groups. We systematically reviewed the literature to assess the impact of implant-based reconstruction on PPBCT levels. MATERIALS AND METHODS: PubMed, Embase, CINAHL, and Scopus databases were searched for relevant articles. We used five search strategies: (persistent pain after breast cancer surgery AND reconstruction), (chronic postsurgical pain AND breast reconstruction), (Breast Implantation [MeSH Terms] AND "Chronic Pain" [MeSH Terms]), (breast reconstruction AND chronic pain), and (postmastectomy pain syndrome AND breast reconstruction). RESULTS: A total of 2281 articles were detected. After scanning for the title and abstract, full-text articles were reviewed to identify the eligible articles. Eleven articles were included in the final review, with seven of these reporting no increased chance of PPBCT following reconstruction with implants, whereas two articles described lower chances of PPBCT following implant-based reconstruction. CONCLUSION: We discovered that implant-based reconstruction does not increase the risk of PPBCT in comparison to other surgical techniques or mastectomy alone. This relationship may facilitate doctors and their patients in the decision-making of the appropriate reconstruction technique to use. In addition, our results should prompt plastic surgeons to prescribe the same dosage and frequency of analgesics to patients undergoing implant reconstruction as they would to their patients not undergoing reconstruction.

BACKGROUND: Extensive composite extremity defects remain a challenge in plastic and reconstructive surgery. To preserve the extremity, we used combined transfer composed of the vascularized fibula flap and a perforator flap from various body parts to reconstruct extensive composite extremity defects. PATIENTS AND METHODS: From January 2004 to December 2018, 14 male patients aged 9 to 55 years with extensive composite extremity defects (large soft-tissue and long bone defect) underwent reconstructive surgery in our institution. The combined transfer surgery consisted of the vascularized fibula bone flap and a perforator flap, such as anterolateral thigh flap, deep inferior epigastric perforator flap, or thoracodorsal artery perforator flap. RESULTS: All fourteen patients were treated successfully using the combined transfer method. The dimensions of the different perforator flaps ranged from 13 × 6 cm2 to 26 × 11 cm2, and the size of the skin paddle of the fibular osteocutaneous flap ranged from 9 × 3 cm2 to 21 × 7 cm2. The median length of the fibular graft was 15 cm. No serious donor site complications were observed. Only one patient developed venous congestion and was salvaged. Another patient had hematoma at the recipient site and underwent debridement. Though all patients achieved bone union (median time of 8 months), two developed a stress fracture of the transferred free fibula. CONCLUSION: We were able to minimize donor site morbidity and avoid amputation in these patients using the combined transfer technique Our results show that the combined transfer of perforator flap and vascularized fibula flap with or without a skin paddle is a feasible reconstruction option for the treatment of the extensive composite extremity defects.

Background: Transverse and oblique deep inferior epigastric artery perforator (DIEP) flaps are widely used in breast, lower extremity, urogenital, head and neck reconstruction. In this report, we present our experience with selecting perforator vessels for transverse and oblique DIEP flaps based on an anatomical study and clinical cases. Materials and methods: A detailed anatomical study of the DIEP flap was carried out using a standardized injection of lead oxide in 10 fresh cadavers. Additionally, 35 male pediatric patients (age 5-12 years) underwent lower extremity reconstruction with a DIEP flap. A transverse DIEP flap was used when the defect template did not exceed zone IV, while an oblique DIEP flap was used when the defect template exceeded zone IV. Results: Perforators located below the umbilicus in zones I and II were rich in transverse anastomoses across the midline of the abdominal wall, which is the basis for the transverse DIEP flap. Perforators lateral to the umbilicus in zone I had true anastomoses with the musculophrenic artery, the morphological basis for the oblique DIEP flap. The DIEP flap design was transverse in 20 patients and oblique in 15. Flap sizes ranged from 8 × 4.5 cm2 to 24 × 9 cm2. One oblique DIEP flap was necrosed totally, and it was repaired by a latissimus dorsi musculocutaneous flap. Conclusion: The transverse DIEP flap design based on the perforator located below the umbilicus in zone I is recommended for small skin and soft tissue defects. We recommend the use of the oblique DIEP flap design based on the perforator lateral to the umbilicus in zone I as an extended flap to reconstruct large tissue defects.
