RESUMO

INTRODUCTION: Burn neck contractures pose a great challenge for reconstructive surgeons. A paucity of literature exist regarding long-term outcomes based on different surgical management strategies. The aim of this study was to evaluate the long-term outcomes of the treatment of neck burn scar contractures and evaluate surgical strategies according to their long-term effectiveness and associated complications. METHODS: A retrospective cohort study was conducted to review outcomes of neck contractures release after burn injury. All patients operated on between January 2009 and February 2023 at a single institution were included. RESULTS: A total of 20 patients developed neck burn scar contracture and were included in this study. The mean age was 32.9 ± 20.3 years. The burn injuries were most commonly thermal (n = 19, 95%). All burn injuries were full-thickness burns, with an average neck defect size of 130.5 ± 106.0 cm2. Overall, 45 surgical scar release procedures were performed on the 20 patients who developed a neck contracture. Patients underwent 1.65 ± 1.04 surgeries on average to address neck contracture. Although 25% of patients only received 1 surgery to treat neck contracture, some patients underwent as many as 8 surgeries. Contracture recurrence (CR) was the most common complication and occurred in 28.9% of the cases. The mean percentage total body surface area did not significantly differ in CR patients (26.7% ± 14.9%) and no-CR patients (44.5% ± 30.2%). However, there was a significant difference (P = 0.01) in the average neck defect size between CR patients (198.5 ± 108.3 cm2) and no-CR patients (81.1 ± 75.1 cm2). CONCLUSIONS: This study showed that risk factors for initial burn scar contractures may differ from those associated with CR, highlighting the importance of neck defect size as a predictor. The study also examines various surgical approaches, with Z-plasty showing promise for managing CR. However, the absence of data on neck range of motion is a limitation. This research underscores the complexity of managing CR and emphasizes the need for ongoing postoperative monitoring.

RESUMO

BACKGROUND: Loss of vision and other ocular defects are a concern with eyelid burn sequelae. This most commonly progresses from eyelid contracture to cicatricial ectropion and lagophthalmos. When left untreated, these may lead to exposure keratitis, ulceration, infection, perforation, and loss of vision. In the case of full-thickness eyelid burns, release and grafting are required. However, there is a paucity of studies on outcomes in eyelid burn surgery treatment, despite concern for permanent ocular damage or loss of vision. The aim of the study is to describe the complication rates in burn eyelid reconstruction at a single center for 14 years. METHODS: A retrospective cohort study was performed of all patients who had sustained eyelid burns and required reconstruction between April 2009 and February 2023. Medical records were obtained from patients' charts. Collected data include demographics, medical history, type of injury, indication for surgery, procedure performed, and complications. RESULTS: A total of 14 patients and 25 eyelids underwent eyelid reconstruction of the 901 total patients with burn-related injuries requiring plastic surgery reconstruction. These patients underwent 54 eyelid surgeries with a mean follow-up time of 13.1 ± 17.1 months. Patients were 71% men and 29% women, with a mean age of 45.1 ± 15.6 years. In 53.7% (n = 29) of the cases, the simultaneous reconstruction of both the upper and lower eyelids was necessary. The reconstruction of the upper and lower eyelid alone represented a smaller percentage (25.9% and 20.4%, respectively). On average, the patients received 3.9 ± 3.5 eyelid surgeries. The overall complication rate was 53.7% (n = 29). The most common complication was ectropion (42.6%, n = 23). Other complications included eye injury (25.9%, n = 14), lagophthalmos (24.1%, n = 13), local infection (7.4%, n = 4), and graft loss (5.6%, n = 3). CONCLUSION: Periorbital burns represent a major challenge that may require complex surgical intervention. Full-thickness skin graft remains the standard of care for patients with eyelid burns. However, there is a high incidence of ectropion that may require reoperation. Further studies examining the conditions of successful eyelid burn procedures may provide guidance on when patients may benefit from eyelid reconstruction during their burn treatment.

RESUMO

ABSTRACT: A 10 year cohort of patients admitted to a verified burn unit were analyzed to assess the role of plastic surgeons in the operative management of those patients. All 3843patients were admitted during this study period. Of these, 1509 of those patients underwent surgical procedures. Plastic surgeons performed 658 operations on these patients, including acute and delayed reconstruction of hand and facial burn injuries. In this population, plastic surgeons played a critical role in acute and reconstructive burn injuries in anatomically complex areas. This series illustrates the need for plastic surgery training in burn care.

RESUMO

Skin grafting is the mainstay treatment in burn patients. However, in the scenario of soft tissue deficit along with exposure of critical structures, free flap is the only reconstructive option to provide adequate coverage. The aim of the study is to review indications and surgical outcomes of burn patients requiring free tissue transfer. A retrospective cohort study was conducted to review all patients who underwent free tissue transfer for burn-related injuries between March 2012 and June 2023. A total of 13 patients required a free flap for their reconstruction. Eleven flaps were performed during the acute care and 2 were performed for delayed reconstruction. Patients were 69% males and 31% females, with a mean age of 45.5 ± 16 years and a mean BMI of 25.4 ± 6.5. The mean follow-up was 13.5 ± 13.9 months. Indications for free tissue transfer were bone exposure (92%) and severe neck burn contracture (8%). Overall complications rate was 54%. Complications included free flap loss (15%), hematoma (15%), vein thrombosis of the anastomosis (15%), infection (8%), amputation (8%), and wound healing issues (23%). Overall, 38% of the patients required re-operations including venous anastomosis revision, hematoma evacuation, debridement, skin grafting, and debulking. Although sometimes free flap remains the only reconstructive option in severe burn-related injuries, it is only rarely used. However, they carry a high risk of complications and should be considered only as the last resort for limb or life-threatening situations.

RESUMO

Environmental exposures are a major risk factor for developing colorectal cancer, and the gut microbiome may serve as an integrator of such environmental risk. To study the microbiome associated with premalignant colon lesions, such as tubular adenomas (TAs) and sessile serrated adenomas (SSAs), we profiled stool samples from 971 participants undergoing colonoscopy and paired these data with dietary and medication history. The microbial signatures associated with either SSA or TA are distinct. SSA associates with multiple microbial antioxidant defense systems, whereas TA associates with a depletion of microbial methanogenesis and mevalonate metabolism. Environmental factors, such as diet and medications, link with the majority of identified microbial species. Mediation analyses found that Flavonifractor plautii and Bacteroides stercoris transmit the protective or carcinogenic effects of these factors to early carcinogenesis. Our findings suggest that the unique dependencies of each premalignant lesion may be exploited therapeutically or through dietary intervention.

RESUMO

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a variant of anaplastic large cell lymphoma (ALCL) associated with textured-surface silicone breast implants. Since first being described in 1997, over 1100 cases have been currently reported worldwide. A causal relationship between BIA-ALCL and textured implants has been established in epidemiological studies, but a multifactorial process is likely to be involved in the pathogenesis of BIA-ALCL. However, pathophysiologic mechanisms remain unclear. One of the hypotheses that could explain the link between textured implants and BIA-ALCL consists in the greater tendency of bacterial biofilm in colonizing the surface of textured implants compared to smooth implants, and the resulting chronic inflammation which, in predisposed individuals, may lead to tumorigenesis. This review summarizes the existing evidence on the role of micro-organisms and rough surface implants in the development of BIA-ALCL. It also provides insights into the most updated clinical practice knowledge about BIA-ALCL, from clinical presentation and investigation to treatment and outcomes.

RESUMO

BACKGROUND AND AIMS: Familial adenomatous polyposis (FAP) is characterized by high risks of colonic and extracolonic tumors. Recent studies have suggested a rising risk for gastric cancer (GC). We sought to define the spectrum of premalignant gastric polyps in FAP, focusing on high-grade dysplasia (HGD). METHODS: The gastric phenotypes of 118 patients diagnosed with FAP or attenuated FAP in our Hereditary Gastrointestinal Cancer Registry were retrospectively reviewed. To analyze the clinical features associated with the diagnosis of HGD, we established an age- and sex-matched control group of FAP patients from our cohort without gastric HGD in a 4:1 ratio. RESULTS: The spectrum and frequency of gastric polyps in individuals with FAP included fundic gland polyps (67.9%), hyperplastic polyps/foveolar hyperplasia (19.6%), tubular adenomas (15.2%), foveolar adenomas (10.7%), and pyloric gland adenomas (6.3%). Ten patients (8.9%) exhibited gastric HGD at a mean age of 55 ± 13 years, and HGD was seen in all polyp types. When compared with control subjects, HGD was associated with a high diversity of gastric polyp histology, prior low-grade dysplasia, severe gastric polyposis, and prior Whipple surgery (P = 2.0E-5, .003, .024, and .04, respectively). Two patients (1.7%) with HGD were diagnosed with GC. However, the remaining 8 patients with HGD have been under surveillance for an average of 5.8 ± 4.5 years without progression to GC. CONCLUSIONS: Gastric HGD in FAP may be more common than previously appreciated. The natural history of HGD is variable, and most patients with HGD do not appear to progress to GC.

RESUMO

BACKGROUND/OBJECTIVES: Patient education is important to families' ability to manage and cope with pediatric atopic dermatitis (AD). We evaluated whether an educational handbook could improve AD symptoms, caregiver confidence in AD management skills, and AD-related quality of life. METHODS: Caregivers of children with AD ages 1 month to 16 years were randomly assigned to the intervention arm (handbook in addition to standard AD management) or the control arm (standard management alone). Caregivers completed self-report outcome questionnaires prior to a clinical visit for AD and at 3-month follow-up. RESULTS: 175 caregivers completed questionnaires at baseline and follow-up. AD symptoms measured by the Patient-Oriented Eczema Measure (POEM) improved in both the handbook and control arms. However, the decrease in the mean POEM score in the handbook arm (-4.4, 95% CI [-5.8, -3.0]) did not differ from that in the control arm (-3.4, 95% CI [-4.8, -2.03]; P = .343). Change in quality of life did not differ between study arms. Among caregivers attending a new patient visit for AD, mean confidence scores (measured from 0 to 100) increased more in the handbook arm (67 [95% CI {60, 74}] to 83 [95% CI {77, 88}]) relative to the control arm (74 [95% CI {65, 82}] to 75 [95% CI {67, 83}]; P = .012). The majority of caregivers rated the handbook as helpful in managing the child's AD. CONCLUSIONS: Despite an adequate sample size, the handbook did not improve AD symptoms more than standard management alone. The handbook improved confidence in management skills for families attending new patient visits for AD.
