The taskforce comprises experts including preventive cardiologists, interventionists, and cardiovascular and plastic surgeons. The consensus focuses on addressing the challenges in diagnosing, treating, and managing complex wounds; incorporates the perfusion evaluation and the advanced vascular wound care team; and highlights the importance of cross-disciplinary teamwork. The aim of this joint consensus is to manage patients with advanced vascular wounds and encourage the adoption of these guidelines by healthcare professionals to improve patient care and outcomes. The guidelines encompass a range of topics, including the definition of advanced vascular wounds, increased awareness, team structure, epidemiology, clinical presentation, medical treatment, endovascular intervention, vascular surgery, infection control, advanced wound management, and evaluation of treatment results. It also outlines a detailed protocol for assessing patients with lower leg wounds, provides guidance on consultation and referral processes, and offers recommendations for various wound care devices, dressings, and products. The 2024 TSOC/TSPS consensus for the management of patients with advanced vascular wounds serves as a catalyst for international collaboration, promoting knowledge exchange and facilitating advancements in the field of advanced vascular wound management. By providing a comprehensive and evidence-based approach, this consensus aims to contribute to improved patient care and outcomes globally.
RESUMO
Recurrence of pressure ulcers following reconstructive surgery occurs frequently, causing a significant burden on the patient and the public health care system. We assessed risk factors for the recurrence of pressure ulcers based on the experience of a single surgeon at our medical centre. We retrospectively analysed patients admitted to our medical centre with stage III and IV pressure ulcers who underwent reconstructive surgery. The hospital database was searched for patients diagnosed with pressure ulcers who underwent reconstructive surgery. Patient characteristics analysed included age, sex, cause and location of defect, comorbidities, lesion size, wound reconstruction methods, operation time, debridement times, duration of hospital stay, and wound complications. Recurrence and mortality rates were retrospectively examined. One hundred and eighty-nine patients were enrolled, and 166 patients with 176 pressure ulcers met our inclusion criteria. All 14 recurrences (7.95%) were followed for at least 1 year. Logistic regression analysis indicated that recurrence was associated with albumin levels (P = 0.001) and wound size (P = 0.043); however, no association was found for body mass index, bacterial profile, comorbidities, localisation, previous surgery, operation time, or time to admission for reconstruction. In conclusion, higher albumin levels were associated with lower recurrence rates in patients who underwent reconstructive surgery.

BACKGROUND: Breast reconstruction is an integral part of breast cancer treatment, and implant-based breast reconstruction is the most commonly used method worldwide. However, there is still no technique that allows surgeons to predict the volume of the required implant. Although computed tomography and magnetic resonance imaging provide adequate representations of the breast, these procedures are time-consuming, expensive, and expose patients to radiation. Therefore, there is a need for safer, noninvasive alternatives for preoperative breast volume measurements. PATIENTS AND METHODS: This study is a prospective review of 12 patients with early-stage breast cancer who underwent nipple-sparing mastectomy and immediate breast reconstruction with implants. Preoperatively, the Artec Eva 3D scanner was used to acquire volumetric measurements of the breasts. Intraoperatively, the volume of the mastectomy specimen was measured using the water displacement method. Correlations among the preoperative breast, mastectomy specimen, and estimated and final implant volumes were analyzed through Pearson correlation coefficient. A correction prediction factor of 85% was applied where necessary. Patient and physician satisfaction were evaluated 3 months postoperatively. RESULTS: Our study found a statistically significant correlation between the preoperative breast volumes measured by the Artec Eva 3D scanner and intraoperative mastectomy specimen volumes (r = 0.6578). There was no correlation between the preoperative breast volumes and final implant volumes, mastectomy specimen volumes and final implant volumes, and estimated implant volumes and final implant volumes. CONCLUSIONS: Although the Artec Eva 3D scanner can offer relatively accurate measurement of breast volumes, multiple studies still need to be done to determine how these data can be applied to the mastectomy procedure and breast implant selection. It may be more applicable for preoperative planning in breast augmentation surgery. Future surgeons should also take into account that variabilities in natural breast size, tumor size, cancer stage, and in patient and physician preferences all influence the outcome of breast reconstruction surgery.

Background and Objectives. Lymph node status is the most important prognostic factor in cutaneous melanoma patients. Recent studies showed that indocyanine green (ICG) fluorescence lymphography helps locating sentinel nodes better. Sometimes, flap reconstruction is needed after wide excision of tumor. Indocyanine green fluorescence also simplifies the intraoperative design of flaps. This study investigates the use of ICG fluorescence in patients with cutaneous melanoma during operation. Methods. We performed a single-center, retrospective study of subjects with cutaneous melanoma using ICG lymphograhy and/or angiography during wide excision of tumor between 2015 and 2019. Patients received a dermal injection of ICG and patent blue (PB) dye. The positive node was excised. Indocyanine green angiography was utilized to visualize better skin paddle during flap reconstruction if needed. Results. A total of 37 sentinel lymph nodes (SLNs) were removed in 12 patients. Indocyanine green successful localization was found in 10 of the 12 patients (83%). Three patients were found with 6 metastatic nodes on final pathology. 100% of these 6 nodes were identified by ICG, while 83% (5/6) were positive PB. Three of the 12 patients received flap reconstruction after operation, and no major complications occurred. Conclusions. ICG dye lymphangiography is a good alternative for locating SLNs in patients with melanoma. It could also visualize well perfusion skin paddle during reconstruction. We reported a reproducible and simple method to utilize ICG fluorescence in cutaneous melanoma patients.

Diabetes-related lower extremity amputations are an enormous burden on global health care and social resources because of the rapid worldwide growth of the diabetic population. This research aimed to determine risk factors that predict major amputation and analyse the time interval from first hospitalisation to amputation by using standard management protocols and Kaplan-Meier survival curves. Data from 246 patients with diabetes mellitus and diabetic foot ulcers from the Division of Plastic and Reconstructive Surgery of the Department of Surgery at XXX Hospital between January 2016 and May 2020 were analysed. Univariate and multivariate analyses of 44 potential risk factors, including invasive ulcer depth and C-reactive protein levels, showed statistically significant differences for those at increased risk for major amputation. The median time from hospitalisation to lower extremity amputation was approximately 35 days. Most patients with abnormal C-reactive protein levels and approximately 70% of patients with ulcers invading the bone were at risk for lower extremity amputations within 35 days. Therefore, invasive ulcer depth and C-reactive protein levels are significant risk factors. Other potential risk factors for major amputation and the time intervals from first hospitalisation to amputation should be analysed to establish further prediction strategies.

This was the first study to analyse patients who sustained severe self-induced burns from this common Asian practice. There is a need to raise public awareness and physician attention about the consequences of preventable burn injuries and the importance of first aid in patients with diabetic neuropathy. Retrospective data on 16 consecutive patients who had diabetes and neuropathy admitted to the plastic surgery ward at the Tri-Service General Hospital from January 1, 2015, to February 2, 2021 with burn injuries because of heat applications were collected and analysed for this study. Age, gender, season, first aid adequacy, comorbidity, interventions, total body surface area (TBSA), degree of burn, aetiology, length of stay (LOS), and status at discharge were reviewed. The mean age of the 16 patients was 65.13 years. The most common burn aetiology was contact (50%), followed by scald (37.5%) and radiation burns (12.5%). TBSA burn averaged ± standard deviation 1.54 ± 1.22. Seven patients (44%) had wound infections, and three patients underwent amputations. The average LOS was 28.2 days. Asian practice of heat application is the common aetiology of severe and preventable burn injuries. Education about neuropathy and the consequences of a burn injury should be provided to patients with diabetes.

INTRODUCTION: Proper wound care along with the use of skin grafts over deep burn wounds has been the standard treatment. However, the goal in burn wound care has shifted from achieving a satisfactory survival rate to improving long-term form and function of the healed wound, which is sometimes hindered by scar contracture. This has prompted surgeons to find alternative ways to treat burn wounds without compromising function. Among burn cases, hand injuries are the most problematic when it comes to delicate function recovery. METHODS: This study presents the results of conjunctive use of a bilayer artificial dermis, negative pressure wound therapy, and split-thickness skin grafts for grafting over acute burn wounds and scar-releasing defects after severe hand burns. RESULTS: Three months after the operation, the scar was soft and pliable, the aesthetic outcome was good, and the patients gained much improvement in hand function and quality oflife. CONCLUSIONS: The combined technique achieved a good scar quality and aesthetic effect on burned hands as well as excellent functional outcome, which resulted in major improvements and an independent life for the patient.

ABSTRACT: Preserving both esthetic and functional outcome remains challenging in facial burn injuries. The major issue is the initial treatment of injury. In this study, we focused on patients with partial-thickness facial burns admitted to the burn unit of Tri-Service General Hospital, Taipei, from November 2016 to November 2018. In 21 included patients, customized mask-style, transparent hydrogel-based dressing was applied to the burns. The mean age of included patients was 37.4 years. The mean area of burn injury was 11.9% of total body surface area, and the mean area of second-degree facial burns was 162.3 cm2. Full reepithelialization took, on average, 10.86 days. Scarring was acceptable in terms of texture and color, and no hypertrophic or keloidal scarring was noted. The mean Vancouver Scar Scale score was 2.07. Use of the hydrogel-based dressing masks seems to be a promising means of reducing pain, providing uninterrupted wound healing, facilitating observation, and positively affecting scarring in patients with second-degree facial burns.

Various animal studies have shown beneficial effects of hypercapnia in lung injury. However, in patients with acute respiratory distress syndrome (ARDS), there is controversial information regarding the effect of hypercapnia on outcomes. The duration of carbon dioxide inhalation may be the key to the protective effect of hypercapnia. We investigated the effect of pre-treatment with inhaled carbon dioxide on lipopolysaccharide (LPS)-induced lung injury in mice. C57BL/6 mice were randomly divided into a control group or an LPS group. Each LPS group received intratracheal LPS (2 mg/kg); the LPS groups were exposed to hypercapnia (5% carbon dioxide) for 10 min or 60 min before LPS. Bronchoalveolar lavage fluid (BALF) and lung tissues were collected to evaluate the degree of lung injury. LPS significantly increased the ratio of lung weight to body weight; concentrations of BALF protein, tumor necrosis factor-α, and CXCL2; protein carbonyls; neutrophil infiltration; and lung injury score. LPS induced the degradation of the inhibitor of nuclear factor-κB-α (IκB-α) and nuclear translocation of NF-κB. LPS increased the surface protein expression of toll-like receptor 4 (TLR4). Pre-treatment with inhaled carbon dioxide for 10 min, but not for 60 min, inhibited LPS-induced pulmonary edema, inflammation, oxidative stress, lung injury, and TLR4 surface expression, and, accordingly, reduced NF-κB signaling. In summary, our data demonstrated that pre-treatment with 10-min carbon dioxide inhalation can ameliorate LPS-induced lung injury. The protective effect may be associated with down-regulation of the surface expression of TLR4 in the lungs.

BACKGROUND: Adequate fluid titration during the initial resuscitation period of major burn patients is crucial. This study aimed to evaluate the feasibility and efficacy of a goal-directed fluid resuscitation protocol that used hourly urine output plus the arterial waveform analysis FloTrac (Edwards LifeSciences, Irvine, Calif) system for major burns to avoid fluid overload. METHODS: We conducted a retrospective cohort study of 43 major burn patients at the Tri-Service General Hospital after the Formosa Fun Coast Dust Explosion on June 27, 2015. Because of the limited capacity of intensive care units (ICUs), 23 intubated patients were transferred from the burn wards or emergency department to the ICU within 24 hours. Fluid administration was adjusted to achieve a urine output of 30 to 50 mL/h, cardiac index greater than 2.5 L/min/m, and stroke volume variation (SVV) less than 12%. The hourly crystalloid fluid infusion rate was titrated based on SVV and hourly urine output. RESULTS: Of the 23 critically burned patients admitted to the ICU, 13 patients who followed the goal-directed fluid resuscitation protocol within 12 hours postburn were included in the analysis. The mean age (years) was 21.8, and the mean total body surface area (TBSA) burned (%) was 68.0. The mean Revised Baux score was 106.8. All patients sustained inhalation injury. The fluid volumes administered to patients in the first 24 hours and the second 24 hours (mL/kg/% total body surface area) were 3.62 ± 1.23 and 2.89 ± 0.79, respectively. The urine outputs in the first 24 hours and the second 24 hours (mL/kg/h) were 1.13 ± 0.66 and 1.53 ± 0.87, respectively. All patients achieved the established goals within 32 hours postburn. In-hospital mortality rate was 0%. CONCLUSIONS: The SVV-based goal-directed fluid resuscitation protocol leads to less unnecessary fluid administration during the early resuscitation phase. Clinicians can efficaciously manage the dynamic body fluid changes in major burn patients under the guidance of the protocol.

INTRODUCTION: Nipple-sparing mastectomy (NSM) and immediate breast reconstruction with gel implants have grown in popularity because of superior aesthetic outcomes. One risk of this procedure is overexcision of the flap leading to inadequate circulation in the breast envelope. METHODS: We investigated 17 cases of NSM and gel implant breast reconstruction. Patients were divided into an infra-areolar incision group and a supra-areolar incision group. Nipple-areolar complex perfusion was evaluated using the SPY imaging system after NSM and gel implant breast reconstruction. We aimed to discover any relationships between the incision method and nipple-areolar complex (NAC) circulation in NSM and gel implant breast reconstruction. RESULTS: For successful breast surgery, awareness of the blood supply to the breast, especially the NAC, is very important. In our study, with the indocyanine green SPY imaging system, most ingress (arterial inflow) and egress (venous outflow) rates in the infra-areolar incision group were better than those in the supra-areolar incision group (P < 0.005). CONCLUSIONS: We have shown that an infra-areolar incision provides better blood flow following NSM and gel implant breast reconstruction. In our experience, in order to prevent the possible ischemia of NAC, we used the smaller gel implants, which is approximately 10 to 20 mL smaller than the original implant size measured by the sizer, if the egress rate of NAC is lower than 0.2. These findings have implications in the clinical setting as surgeons have a choice to provide a better outcome for patients.

INTRODUCTION: Plantar hyperkeratosis, such as corns and calluses, is common in older people and associated with pain, mobility impairment, and functional limitations. It usually develops on the palms, knees, or soles of feet, especially under the heels or balls. There are several treatment methods for plantar hyperkeratosis, such as salicylic acid plaster and scalpel debridement, and conservative modalities, such as using a shoe insert and properly fitting shoes. METHODS: We present an effective method of reconstructing the wound after corn excision using a split-thickness sole skin graft (STSSG). We harvested the skin graft from the arch of the sole using the dermatome with a skin thickness of 14/1000th inches. RESULTS: Because the split-thickness skin graft, harvested from the sole arch near the distal sole, is much thicker than the split-thickness skin graft from the thigh, it is more resistant to weight and friction. The healed wound with STSSG coverage over the distal sole was intact, and the donor site over the sole arch had healed without complication during the outpatient follow-up, 3 months after surgery. CONCLUSIONS: The recovery time of STSSG for corn excision is shorter than that with traditional treatment. Therefore, STSSG can be a reliable alternative treatment for recurrent palmoplantar hyperkeratosis.

Pressure sores remain a common health problem, particularly among the physically limited or bedridden elderly, and can cause significant morbidity and mortality. This study aimed to present our surgical treatment and strategy for patients with multiple pressure sores. Between January 2010 and December 2016, 18 patients were enrolled. After adequate debridement, pressure sores were managed based on our treatment protocol. Patients' age, aetiology, defect size and location, flap reconstruction, outcome, and follow-up period were reviewed. A total of 10 men and 8 women (average age, 82.3 years) with a mean follow-up period of 28.3 months (6-72 months) were included. The mean defect area was 63.7 cm2 . The most common aetiology of the bedridden state was cerebrovascular accident (38.89%), and the most frequent sores were trochanteric pressure sores (53.57%). The average operative time and blood loss were 105.5 minutes and 100.8 mL, respectively. No haemodynamic variation or blood transfusion was noted during the surgery. The complication rate for each sore was 10.7%, including late recurrence. In conclusion, treating pressure ulcers requires careful patient education, intensive multidisciplinary optimisation, and meticulous wound care, and our treatment protocol ensures a shorter surgery time, less bleeding, and low complication rate.

The basic principle of donor site selection is to take skin from areas that will heal with minimal scarring while balancing the needs of the recipient site. For skin loss from the lower legs and feet, the most common harvest site for split-thickness skin grafts is the anterior or posterior thigh; grafts from the plantar areas have been mostly used to cover the volar aspect of digits and palms. Between September 2015 and September 2017, 42 patients with areas of skin loss on the legs or feet were treated with plantar skin grafts because of their cosmetic benefits and the convenience of the surgical procedure and postoperative wound care. Our technique of harvesting a single layer of split-thickness skin graft (0.014 in. thick) from a non-weight-bearing area of the foot of the injured leg is simple and provided good functional and cosmetic outcomes at both the donor and recipient sites. All patients were very satisfied with the recovery progress and final results. Therefore, in the management of skin defects in the lower legs or feet that comprise less than 1.5% of the total body surface area, our surgical method is a reliable alternative to anterior or posterior thigh skin grafting.

BACKGROUND: The use of implants is still the most common procedure for breast reconstruction because they are easy, less painful than tissue transplants, and do not need a donor site. However, it is challenging to find a suitable implant for patients with small breasts, and some women fear foreign bodies and possible complications or reoperations. Autologous breast reconstruction using the pedicled latissimus dorsi (LD) myocutaneous flap without an implant provides a good option for Asian women with small breasts. MATERIALS AND METHODS: Between June 1992 and December 2015, 31 patients underwent breast reconstruction with 33 LD flaps (29 unilateral and 2 bilateral). The skin paddle of the flap was designed with an oblique or transverse pattern depending on the mastectomy defect and the elasticity of skin. The thoracodorsal nerve was divided during flap harvesting to prevent a "twitching breast" postoperatively. Patients refused to have contralateral breast augmentation except for 2 with bilateral simultaneous augmentation after mastectomy bilaterally. Outcome measures were flap survival, shape and contour, symmetry of breast, complication of flap and donor site, patient satisfaction, and any local tumor recurrence or metastasis. RESULTS: The mean patient age was 46.7 years (range, 27-72), and the mean body mass index was 22.5 kg/m (range, 18.6-30). The mean size of the harvested skin paddle was 11.9 × 5.0 cm (range, 10 × 3 cm to 15 × 9 cm). Mean operative times were 200.8 minutes (range, 112-230 minutes) and 305 minutes (range, 300-310 minutes) for unilateral and bilateral reconstructions, respectively. Pathology reports showed a negative safety margin in all cases. Most cases were of invasive duct carcinoma (58%). All LD flaps survived, and the wounds healed satisfactorily over a mean follow-up of 49.9 months (range, 3-161 months). Donor sites were closed primarily with a hidden linear scar under the dorsal bra strap. Donor site morbidities were mainly seromas (15%), which were treated conservatively in most patients. CONCLUSIONS: The LD flap produced good autologous tissue for reconstruction, and no implants were needed for Asian women with small breasts. The reconstructed breasts showed good shape, contour, and symmetry. The results of donor site were acceptable and no significant functional loss. There were no major complications, and patient satisfaction was high.

BACKGROUND: Although autogenous tissue-based breast reconstruction has been widely used in the past decade, implant-based breast reconstruction is more often used in Taiwan because Asian women are generally slender with small breasts. For patients with very small breasts, it is hard to achieve the goal of reconstructing a similar breast to the contralateral one, even with the smallest size implant available commercially. Therefore, these patients need not only breast reconstruction but also contralateral breast augmentation. Here we report the surgical outcomes and cosmetic results of breast reconstruction using cohesive gel implants combined with simultaneous contralateral breast augmentation. MATERIALS AND METHODS: A retrospective chart review was conducted to identify all patients with AA-sized to B-sized breast cups undergoing expander-implant reconstruction combined with contralateral breast augmentation between 2002 and 2015. Thirty patients were included. For each patient, patient profile (age, body mass index, and initial breast size), type and stage of breast cancer, surgical information (including implant sizes and the type of reconstruction and augmentation), and postoperative subjective pain scales were recorded. Outcomes were analyzed by identifying complications, the need for surgical revision, the presence of local or distant metastases, and patient satisfaction ratings. RESULTS: At a mean 2.3-year follow-up (range, 4 months to 12 years), problems occurred in 7 of the 30 patients, with 9 complications in 8 reconstructed breasts and in 1 augmented breast. Complications were mostly capsule contracture. Aesthetic satisfaction was rated as "excellent" or "good" by most of the patients, and only 1 commented "poor" on both overall and reconstructed results because of postoperative radiotherapy-associated skin necrosis. The total mean subjective pain scale was 1.9/10; a higher mean pain scale of 3.08 was noted in those patients undergoing augmentation with no extra incision. CONCLUSIONS: This is the first report of implant-based breast reconstruction with simultaneous contralateral augmentation in Taiwan, showing its efficacy, safety, and good cosmetic outcomes with relatively low complication and revision rates.

Mutilated hand injuries are a profound challenge to the plastic surgeon, and such injuries often lead to limb loss and severe functional impairment. Hyperbaric oxygen therapy (HBOT) appears to counteract tissue hypoxia and stimulate acute wound healing. This study was performed to evaluate the efficacy of HBOT as an adjunctive therapy in patients with a mutilated hand injury. Between January 2006 and December 2014, 45 patients with a mutilated hand injury were enrolled. After reconstruction or revascularisation, patients underwent 120 minutes of HBOT with oxygen at 2·5 atmospheres absolute while breathing 100% oxygen. Outcomes such as amputee survival and surgery-related complications were recorded. The patients were 38 men and 7 women with average age of 37·2 years (range 18-62). The mean defect area was 131·5 cm2 (range 40-300). Most patients experienced a pure crush injury (53%). The average number of operations from the initial debridement to the first reconstruction was 3·8 (range 1-6). A total of 33 patients (73%) underwent replantation during the initial reconstruction. For flap coverage, most patients received a free flap using an anterolateral thigh flap (18 patients) or local flap using an abdomen/groin flap (nine patients). The average time from the first reconstruction or revascularisation to the first HBOT was 6·5 hours (range 2-12). The average number of HBOT sessions was 9·1 (range 6-14 sessions). The survival rate of the replanted fingers was 81%, and the survival rate of the palms was 100%. Most complications in the initial reconstruction involved partial loss of an avulsed flap, and most complications in the chronic stage (≥3 months) involved scar contracture. When combined with delicate microsurgery, early intervention using adjunctive HBOT was effective in preserving partially viable tissue and restoring hand function in patients with a mutilated hand injury.

Alginate is a natural rich anionic polysaccharide (APS), commonly available as calcium alginate (CAPS). It can maintain a physiologically moist microenvironment, which minimises bacterial infection and facilitates wound healing at a wound site. Patients with burn injuries suffer from pain and an inflammatory response. In this study, we evaluated the CAPS dressing and traditional dressing containing carboxymethyl cellulose (CMC) for wound healing and scar tissue formation in a burn model of rat and swine. In our pilot study of a burn rat model to evaluate inflammatory response and wound healing, we found that the monocyte chemoattractant protein (MCP)-1 and transforming growth factor (TGF)-ß were up-regulated in the CAPS treatment group. Next, the burn swine models tested positive for MCP-1 in a Gram-positive bacterial infection, and there was overproduction of TGF-ß during the burn wound healing process. Rats were monitored daily for 1 week for cytokine assay and sacrificed on day 28 post-burn injury. The swine were monitored over 6 weeks. We further examined the pain and related factors and inflammatory cytokine expression in a rodent burns model monitored everyday for 7 days post-burn. Our results revealed that the efficacy of the dressing containing CAPS for wound repair post-burn was better than the CMC dressing with respect to natural wound healing and scar formation. The polysaccharide-enriched dressing exerted an antimicrobial effect on burn wounds, regulated the inflammatory response and stimulated anti-inflammatory cytokine release. However, one pain assessment method showed no significant difference in the reduction in levels of adenosine triphosphate in serum of rats after wound dressing in either the CAPS or CMC group. In conclusion, a polysaccharide-enriched dressing outperformed a traditional dressing in reducing wound size, minimising hypertrophic scar formation, regulating cytokines and maximising antimicrobial effects.

Pressure sores are often observed in patients who are bedridden. They can be a severe problem not only for patients and their caregivers but also for plastic surgeons. Here, we describe a new method of superior gluteal artery perforator flap harvesting and anchoring with the assistance of intraoperative indocyanine green fluorescent angiography. In this report, we describe the procedure and outcomes for 19 patients with grades III and IV sacral pressure sores who underwent the operation between September 2015 and November 2016. All flaps survived, and two experienced wound-edge partial dehiscence. With the assistance of this imaging device, we were able to acquire a reliable superior gluteal artery perforator flap and perform modified operations with it that are safe, easy to learn and associated with fewer complications than are traditional.

BACKGROUND: Evidence reveals that hypercapnic acidosis (HCA) modulates immune responses. However, the effect of HCA on allogenic skin graft rejection is unknown. We examined whether HCA might improve skin graft survival in a mouse model of skin transplantation. METHODS: A major histocompatibility-complex-incompatible BALB/c to C57BL/6 mouse skin transplantation model was used. Animals were divided into sham control, air, and HCA groups. Mice in the HCA group were exposed daily to 5% CO2 in air for 1 h. Skin grafts were harvested for histologic analyses. Nuclear factor (NF)-κB activation was determined in harvested draining lymph nodes. Spleen weights and serum levels of tumor necrosis factor-α and chemokine (C-X-C motif) ligand 2 were serially assessed after skin transplantation. RESULTS: Skin allografts survived significantly longer in the HCA group of mice than those in the air group. Allografted mice in the air group underwent a 2.1-fold increase in spleen weight compared with a 1.1-fold increase in the mice with HCA on day 3. There were increased inflammatory cell infiltration, folliculitis, focal dermal-epidermal separation, and areas of epidermal necrosis in the air group that were reduced with HCA treatment. In the HCA group, CD8(+) T cell infiltration at day 7 decreased significantly but not CD4(+) T cell infiltration. In addition, HCA significantly suppressed serum tumor necrosis factor-α on days 1 and 3 and chemokine (C-X-C motif) ligand 2 on days 1 and 10. Furthermore, the HCA group had remarkably suppressed NF-κB activity in draining lymph nodes. CONCLUSIONS: HCA significantly prolonged the survival of incompatible skin allografts in mice by reducing proinflammatory cytokine production, immune cell infiltration, and NF-κB activation.
