RESUMO

Fournier gangrene (FG) is a life-threatening necrotizing soft-tissue infection of the perineum and external genitalia, which primarily occurs in obese, diabetic males. The mainstay of treatment is source control via early aggressive surgical excision. Wide surgical excision can result in significant soft tissue defects that can be disfiguring and difficult to close. The most common method of closure is split-thickness skin grafting (STSG). Recently, autologous skin cell suspension (ASCS) technology has been used in addition to STSG to provide better wound healing and closure. This patient experienced excellent wound progression, following FG, through the application of ASCS with STSG, despite challenges related to the wounds, anatomical location, comorbidities, size, and the patient's medical history.

RESUMO

BACKGROUND: Platelets are critical in maintaining homeostasis and immune response in burn patients. The concentration of platelets decreases in burn patients, and any intervention that increases serum platelet concentration can prevent serious consequences and patient death. The present study aimed to assess the impact of skin graft surgery on burn patients' platelet counts. METHODS: In this non-randomized clinical trial, 200 burn patients were investigated. The patients were recruited from the surgical ward of Imam Khomeini Teaching Hospital during the first six months of 2021. After completing the checklist, patients underwent skin graft surgery. Blood was taken from the patients during surgery in the operating room and on the third and fifth day after the surgery to check platelets. Data analysis was conducted using SPSS software (ver. 22.0). RESULTS: Most patients (63.5%) were male, and 73 (36.5%) were female. One hundred eighty-one patients (90.5%) had deep burns, and 19 (9.5%) had superficial burns. The mean burns percentage in the patients was 19.3 ± 15.4%, the lowest was 2%, and the highest was 90%. The most common burns were caused by flame (42%) and boiling water (30.5%). The patients' outcomes revealed that 6% gained complete recovery, 86.5% partial recovery, 2.5% showed transplant rejection, and 5% died. Mean platelet levels in deceased patients had an upward trend. The mean platelet counts of patients were elevated during surgery (289,855 ± 165,378), decreased three days after surgery (282,778 ± 317,310), and elevated again five days after surgery (330,375 ± 208,571). However, no significant difference was found between the mean platelet counts during surgery, the third and fifth days after surgery in patients undergoing skin grafts (P = 0.057). CONCLUSIONS: This study suggests that skin graft positively increases the patient's platelets. Further studies are needed to confirm the findings and elucidate the mechanism.

RESUMO

Aplasia cutis congenita (ACC) is a rare congenital disease defined by the absence of skin, most commonly on the scalp. While the exact incidence remains uncertain, ACC presents a significant challenge in clinical management due to its variable presentation and associated complications. We present the case of a newborn male with a large scalp defect attributed to ACC, complicated by a life-threatening scalp hemorrhage. Despite challenges in management, including recurrent infections and failed skin grafts, the patient ultimately achieved satisfactory healing following a series of surgical interventions, including local transposition flap procedures. This case underscores the importance of a multidisciplinary approach to managing ACC, tailored to individual patient characteristics and associated risks. While discrete lesions of ACC typically have a favorable prognosis, extensive defects pose significant risks of morbidity and mortality, highlighting the need for careful consideration of treatment options and close clinical monitoring of affected individuals.

RESUMO

Loss of sensitivity in the operated area is common after some plastic surgery procedures and promotes accidental trauma on a daily basis. Several studies showed that a loss of sensitivity is constant after an abdominoplasty. We report here the cases of three 3rd degree burns by contact, at the subumbilical level, with a hot water bottle soon after an abdominoplasty, responsible for significant aesthetic sequelae.

RESUMO

This technical note addresses the complexities of reconstructive surgery for malignant skin lesions in the lower nasal aperture and pericolumellar region. Traditional solutions, such as free skin grafts, face challenges in maintaining attachment to the surgical site without adequate support. Nasal packing, a common approach, obstructs the nasal opening and compromises air passage, hindering ventilation. The use of a nasal trumpet has proven beneficial in maintaining nasal patency in various cases, but it falls short of addressing the specific challenges posed by reconstructive surgery. The proposed solution involves a novel device comprising a nasal cannula, surgical sponge, and fine mesh gauze with 3% bismuth tribromophenate. This combination serves a triple purpose: the nasal cannula facilitates air passage, the surgical sponge applies controlled pressure around the nasal opening to aid graft adhesion, and the gauze with bismuth tribromophenate promotes wound healing and prevents infection. The assembled device is inserted into the nostril, anchored to the patient's skin with silk stitches. This innovative approach offers a practical solution for maintaining nasal patency, promoting graft adherence, and supporting wound healing in reconstructive surgery.

RESUMO

BACKGROUND: Multiple trichoepitheliomas are rare benign adnexal tumours that present a unique challenge both to the patient and the managing physician. The multiple nature of the lesion and face being a common location often causes cosmetic concern and psychosocial challenges. Physicians on the other hand face the challenge of providing an ideal treatment with a satisfactory outcome. Dermabrasion and laser therapy have been used to treat this lesion successfully, though they require multiple sessions, and recurrence is common. These options are however either not available or unaffordable in low-resource countries such as Nigeria. Surgical excision though an option, has rarely been advocated due to scarring, leading some experts to offer no treatment at all in developing nations. We report a challenging case of sporadic multiple trichoepitheliomas successfully treated with surgical excision and full-thickness skin graft. METHOD: Following diagnosis, the patient was counselled on the procedure, the risks and benefits. She had en-bloc excision of the lesion, and full-thickness skin graft harvested from the right groin was transplanted and anchored with Monocryl 5-0. All wounds were dressed, and the graft site was reviewed on day 10. She was discharged for outpatient follow-up. RESULT: Graft take was 95%. Epidermolysis which was seen on postoperative day 10 resolved. Hypertrophic scar on the ala nasi is softening on scar massage, and the patient is very satisfied with the outcome. CONCLUSION: Surgical excision can be a valuable tool in low-resource settings for the management of multiple trichoepitheliomas.


CONTEXTE: Les trichoépithéliomes multiples sont des tumeurs annexielles bénignes rares qui présentent un défi unique à la fois pour le patient et le médecin traitant. La nature multiple de la lésion et le visage étant un site commun entraînent souvent des préoccupations esthétiques et des défis psychosociaux. Les médecins, de leur côté, sont confrontés au défi de fournir un traitement idéal avec un résultat satisfaisant. La dermabrasion et la thérapie au laser ont été utilisées avec succès pour traiter cette lésion, bien qu'elles nécessitent plusieurs séances et que la récidive soit fréquente. Ces options ne sont cependant pas disponibles ou abordables dans les pays à faibles ressources tel que le Nigeria. L'exérèse chirurgicale, bien qu'une option, a rarement été préconisée en raison des cicatrices, conduisant certains experts à ne proposer aucun traitement du tout dans les pays en dével oppement . Nous rappor tons un cas difficile de trichoépithéliomes multiples sporadiques traités avec succès par exérèse chirurgicale et greffe de peau totale. MÉTHODE: Après le diagnostic, la patiente a été informée de la procédure, des risques et des avantages. Elle a subi une exérèse en bloc de la lésion, et une greffe de peau totale prélevée dans l'aine droite a été transplantée et fixée avec du Monocryl 5-0. Toutes les plaies ont été habillées, et le site de la greffe a été examiné le 10e jour. Elle a été renvoyée pour un suivi en consultation externe. RÉSULTAT: La prise de greffe était de 95 %. L'épidermolyse observée le 10e jour postopératoire a disparu. La cicatrice hypertrophique sur l'aile du nez s'assouplit avec le massage de la cicatrice, et la patiente est très satisfaite du résultat. CONCLUSION: L'exérèse chirurgicale peut être un outil précieux dans les contextes à faibles ressources pour la prise en charge des trichoépithéliomes multiples. MOTS-CLÉS: Trichoépithéliomes multiples, Thérapie au laser, Électrocautérisation, Exérèse chirurgicale, Greffe de peau totale.

RESUMO

Degloving injuries of the upper limbs, common in industrial settings, pose significant reconstructive challenges. The injury's severity dictates the approach, from primary closure and skin grafting to complex free tissue transfer. Proper preparation of both the wound bed and degloved tissue is crucial, as the degloved tissue can serve as an effective biological dressing. Furthermore, salvaging this tissue and preparing it as a full-thickness skin graft can lead to good graft take-up and healing. This case report presents a 23-year-old male who sustained a severe crush and degloving injury to his right hand from heavy machinery. Using meticulous debridement and careful preparation of the degloved tissue, we achieved optimal wound management and coverage. This case highlights the critical role of preparation technique in achieving successful outcomes and underscores the potential benefits of using the degloved tissue prior to complex reconstructive scenarios, offering valuable insights for clinical practice.

RESUMO

Severe burns on the forehead are rare; well-conducted initial surgical treatment also limits the occurrence of sequelae. Therefore, indications for repairing the forehead arise from complex burns often extending to adjacent units. Repair techniques depend on the location and size of the lesions, associated nearby damage, and the patient's ability to withstand the burden of treatment. Management at the acute stage determines the sequelae; excision-grafting is the standard treatment, but it yields good results only if the fundamental principles of repair are respected: intervention within the 10th and 15th days post-burn, graft harvesting from the cephalic extremity or the upper part of the thorax and arms, and respect for the frontal unit. Sequelae management follows the same imperatives and typically requires skin expansion: front expansion for skin flaps if enough frontal skin is still available, upper thorax expansion for full thickness skin grafts if the frontal scar is too extensive. However, the excellent results obtained should not conceal the significant constraints associated with skin expansion.

RESUMO

The effects of the novel synthetic peptide, A7-1, on wound healing and skin grafts were evaluated in a C57BL/6 mouse model. Two 15-mm wide circular skin excisions were made on the backs of mice and to each excision, 100 µM A7-1 or normal saline was applied daily. The treatments were applied and sutured for skin graft analysis. Digital photos were acquired on days 4, 7, 11, and 14 and fluorescein angiography was conducted. Wound sizes were verified using stereoscopic microscopy. Histological analysis was performed via hematoxylin and eosin staining and Masson's trichrome staining. Western blotting was performed using vascular endothelial growth factor. Using a stereoscopic microscope, significantly faster wound healing (17.3%) and skin graft healing (16.5%) were observed in the A7-1 treatment group in comparison to that of the control. The angiogenesis was significantly faster in fluorescein angiography examination in wound healing (11%) and skin grafts (15%). However, the average completion of epithelization (overall time for wound healing), did not show any significant differences. In comparison to the control, the new protein, A7-1, led to significantly faster wound healing in the initial angiogenesis.

RESUMO

Penile strangulation secondary to utilization of a constrictive ring is a rare urologic emergency that requires urgent decompression to prevent prolonged vascular obstruction resulting in necrosis and gangrene. Current literature is mainly comprised of case presentations that focus on management in the acute setting via removal of the ring. Herein, we describe surgical management of a patient who presents in delayed fashion after self-removal of the constrictive ring. We discuss our penectomy-sparing technique of debridement and split thickness skin graft.

RESUMO

Full-thickness skin graft (FTSG) reconstructions of lower limbs are especially prone to wound complications. Negative pressure wound therapy (NPWT) enhances wound healing, but no broad evidence exists if it promotes graft take of lower leg FTSGs. In this investigator-initiated, prospective, randomised and controlled trial, 20 patients with ambulatory FTSG reconstruction for lower limb skin cancers were randomised for postoperative treatment with either NPWT, or conventional dressings. As outcomes, adherence of the skin graft 1 week postoperatively, any wound complications within 3 months, including ≥3 weeks delayed wound healing, and the number of additional postoperative visits were compared. In both groups, grafts adhered equally well (p = 0.47); 80% of NPWT-treated and 100% of control group grafts adhered >90%. There was no significant difference in the number of postoperative complications/delayed wound healing (p = 0.65); 70% of patients in the NPWT and 50% in the control group developed a wound complication. Both groups had an equal number of patients with at least three additional control visits (p = 1.0). The study was discontinued after 20 patients were recruited, as no benefit from NPWT was seen. To conclude, the study showed no benefit from NPWT for lower limb FTSGs.

RESUMO

Objective: To investigate the feasibility of leg wound closure and reconstruction of maxillofacial soft defect by a fusiform-designed skin paddle in fibula free flap (FFF). Methods: Fifty patients who underwent FFF for reconstruction of maxillofacial soft defect were divided into two groups. The fusiform group (20 patients) was treated using a fusiform-designed skin paddle in FFF (skin paddle width less than 2 cm), and leg wound was closed using primary suturing. Reconstruction of the maxillofacial soft defect or filling of dead space was achieved by folding the fusiform skin paddle. The conventional group (30 patients) was treated using the conventional-designed skin paddle (skin paddle width no less than 2.5 cm). The leg wound was closed using mattress suturing or skin graft, while reconstruction of the maxillofacial soft defect or filling of dead space by conventional way. The average postoperative length of hospital stay, healing time of leg wound, and post-surgical complications were recorded at least 6 months after the surgery. Results: Compared with traditional method, the fusiform-designed skin paddle reduced the average healing time of the leg wound (fusiform group: 11.05 days, conventional group: 14.77 days, P < 0.05). The average length-to-width ratio in fusiform group was significantly greater than that of in conventional group (fusiform group: 5.85, conventional group: 2.93, P < 0.05), and no difference was observed on the graft size of skin paddle between two groups (fusiform group: 23.13, conventional group: 27.13, P > 0.05). The post-surgical early complications of the leg wound in the conventional group were higher than that of in the fusiform group (fusiform group: 0%, conventional group: 6.67%), while the post-surgical late complication of the donor site between the two groups showed no case. Healing disorders of maxillofacial soft reconstruction in the conventional group were higher than that of in the fusiform group (fusiform group: 5.26%, conventional group: 20.69%). Conclusions: Fusiform-designed skin paddle for closure of the leg wound and maxillofacial soft defect is a feasible alternative to the conventional- designed skin paddle. The fusiform- designed skin paddle resulted in the less postoperative length of hospital stay, shorter healing time of leg wound and less complication.

RESUMO

INTRODUCTION AND IMPORTANCE: The use of radiation therapy for infantile hemangiomas 30 years ago has led to severe consequences in adulthood. CASE PRESENTATION: This article shares the experience of using multiple reconstructive procedures to treat radiation-induced hemifacial sequelae for capillary malformations. Based on the damaged anatomical surgical units, appropriate reconstructive materials are used for the surgery. Thin antero-lateral thigh (ALT) flaps cover lesions on the forehead and cheeks, while a skin expander covers the temporal scalp lesion. Autologous grafting covers damage in both eyelids. CLINICAL DISCUSSION: Choosing a suitable reconstructive material will provide aesthetic outcomes such as facial symmetry, skin color compatibility, and textural similarity in the constructive areas for the patient. The patients were highly satisfied with the surgical results. CONCLUSION: Using appropriate surgical techniques and materials, along with meticulous attention to facial integrity, can achieve optimal aesthetic and functional outcomes in patients with severe facial disfigurement from radiation therapy. A thorough understanding of pathophysiology and anatomy, along with skillful execution, can result in a successful outcome and improved quality of life.

RESUMO

Tissue-engineered products (TEPs) are at the forefront of developmental medicines, precisely where monoclonal antibodies and recombinant cytokines were 30 years ago. TEPs development for treating skin wounds has become a fast-growing field as it offers the potential to find novel therapeutic approaches for treating pathologies that currently have limited or no effective alternatives. This review aims to provide the reader with the process of translating an idea from the laboratory bench to clinical practice, specifically in the context of TEPs designing for skin wound healing. It encompasses historical perspectives, approved therapies, and offers a distinctive insight into the regulatory framework in Brazil. We explore the essential guidelines for quality testing, and nonclinical proof-of-concept considering the Brazilian Network of Experts in Advanced Therapies (RENETA) and International Standards and Guidelines (ICH e ISO). Adopting a multifaceted approach, our discussion incorporates scientific and industrial perspectives, addressing quality, biosafety, non-clinical viability, clinical trial and real-word data for pharmacovigilance demands. This comprehensive analysis presents a panoramic view of the development of skin TEPs, offering insights into the evolving landscape of this dynamic and promising field.

RESUMO

Introduction: Skin grafting is a routinely employed technique to cover the skin defect. Though the skin grafts are technically effortless, they are tiresome because of the prolonged duration of hospital stay, labor-intensive, demanding repeated dressings, and also create a second wound. Platelet-rich plasma (PRP) is one that has a higher concentration of platelets than the blood. Alpha granules of the platelets are rich in growth factors. Aims and Objectives: To assess the effect of PRP on split-thickness skin graft uptake and donor site healing. Materials and Methods: In a single-center-based prospective study done from August 2018 to June 2020, 60 patients with acute and chronic wounds were divided into two equal groups. Autologous PRP was applied on the recipient wound bed and donor site in PRP group, and conventional methods like staples/sutures were used to anchor the skin grafts and standard of care of the donor site in a control group. Results: Instantaneous graft adhesion was observed in all patients of PRP group. The first graft inspection was delayed. Seroma, hematoma, total number of dressings, and duration of stay in hospital were significantly reduced in the PRP group. Donor site pain in the postoperative period was notably reduced in PRP group. PRP also remarkably hastened the donor site healing. Conclusion: The application of PRP promotes graft take, minimizes complications, enhances donor site wound healing, mitigates donor site pain, and has immense economic benefits due to the reduced number of dressing changes and shorter hospital stay.

RESUMO

OBJECTIVE: In this experimental study, we aimed to determine whether platelet-rich plasma (PRP) is a suitable preservative for dermo-epidermal grafts. An additional objective was to investigate how long grafts can be stored without biological degradation. METHODS: We compared pig skin graft preservation using PRP versus saline solution and crystalloid Custodiol®, which is used for hypothermic preservation of organs for transplantation. Grafts (10 × 10 mm) were placed on gauze impregnated with one of the tested solutions, and stored for 3, 7, 11, and 15 days at a constant temperature of 4°C. We evaluated a total of 240 pig skin samples: 120 by histopathology and 120 by fluorescence optical microscopy. RESULTS: Overall, Custodiol® solution appeared to be the best medium for preservation of dermo-epidermal grafts, with beneficial properties manifested on days 7 and 11. Although we expected PRP to be a better preservative than saline, this was not confirmed by our results, as we found no significant difference between these two media. In fact, by day 3, the histopathological results were better with standard saline solution than with PRP. On day 15, with each tested solution, some samples showed histological changes that are incompatible with graft viability. CONCLUSION: Overall, Custodiol® appears to be the best medium for dermo-epidermal graft preservation. Moreover, the present findings suggest a maximum graft storage time of 11 days in all of the tested solutions. We do not recommend using grafts stored for 15 days, due to isolated signs of graft biodegradation with all solutions.
