ABSTRACT

OBJECTIVE: Integra Dermal Regeneration Template (IDRT) (Integra LifeSciences, US) is a bioengineered dermal matrix that has been widely used in burn reconstruction since its first description. However, little is reported on its use in oncologic dermatological defects. Our objective was to evaluate reconstruction using IDRT on cutaneous tumour defects. METHOD: We conducted a two-year retrospective review of patients with skin tumours who had an excision surgery, followed by reconstruction with IDRT, as a mid-step towards a final autograft procedure: a split-thickness skin graft. The records of all patients at a single academic institution were queried from the electronic medical record using data obtained from the operating surgeon. RESULTS: We identified 13 patients with different tumour types and locations. The mean defect size was 105.92cm². The matrix take rate was 92.3% and average postoperative day for definite autograft was 20 days. Patients were followed for a period of up to 12 months. Of the patients, one had exposed bone without periosteum; another patient showed recurrence six months after matrix placement, requiring a new second two-stage IDRT-autograft procedure before radiation therapy. Patients reported complete satisfaction with the cosmetic, functional and oncological results. No cases of infection were encountered. CONCLUSION: IDRT is a valid option for the reconstruction of oncologic surgical defects of the skin and can be used in different anatomical locations. Specifically, it is an alternative to the reconstructive ladder when grafts and local flaps are not possible in those patients, and an option for patients who will eventually need adjuvant radiotherapy.

ABSTRACT

Introducción y objetivo: Considerando que las úlceras crónicas de miembros inferiores son de evolución tórpida y de difícil tratamiento, con la presencia de biofilm en el lecho de la herida asociado a un proceso de inflamación crónica que interrumpe el desarrollo de la cicatrización normal, proponemos un tratamiento con sustitutos cutáneos (piel cadavérica y piel artificial) para adecuar el lecho de la herida y prepararlo para la reconstrucción definitiva con autoinjerto.Maaterial y método.Cohorte retrospectiva de 22 pacientes sometidos a cirugía reconstructiva de úlceras crónicas de origen vascular o postraumático en miembros inferiores en el Hospital Alemán de Buenos Aires (Argentina) en el período de febrero de 2017 a diciembre de 2019.En la primera etapa quirúrgica se realizó desbridamiento de lesiones con cobertura inmediata de piel cadavérica (aloinjerto) en toda la superficie de la herida y en un segundo tiempo quirúrgico, retirada del aloinjerto y reconstrucción con autoinjerto de piel de espesor parcial o piel artificial Integra® (Lifesciences Corp., Plainsboro, NJ, EE.UU.) y autoinjerto delgado de piel.Resultados.Analizamos 22 pacientes de los que 15 fueron mujeres (68.18%), con edad promedio de 72.5 años. La media de la superficie de las úlceras crónicas fue de 111.76 cm2. La etiología fue vascular en 12 pacientes (54.54%) y en 10 de origen postraumático (45.45%). El prendimiento de la piel cadavérica se logró en 20 pacientes (90.90%), de los que en 18 fue del 100% y en 2 del 50%. El aloinjerto actuó como sustituto cutáneo transitorio para la preparación del lecho receptor. Todos los pacientes evidenciaron disminución del proceso inflamatorio, exudado y dolor.Conclusiones.En nuestra experiencia, el injerto de piel cadavérica es una opción válida en la preparación del lecho para el tratamiento de úlceras crónicas rebeldes al tratamiento no quirúrgico.

Background and objective: Considering that chronic ulcers of the lower limbs are of torpid evolution and difficult to treat, with the presence of biofilm in the wound bed associated with a process of chronic inflammation that interrupts the development of normal healing, we propose a treatment with skin substitutes (cadaveric skin and artificial skin) to adapt the wound bed and prepare it for the definitive reconstruction with autograft.Methods.Retrospective cohort of 22 patients who underwent reconstructive surgery for vascular or post-traumatic chronic ulcers in the lower limbs at the Hospital Alemán in Buenos Aires (Argentina) from February 2017 to December 2019. In the first surgical stage, the ulcers were debrided with immediate coverage of cadaveric skin (allograft) and in a second surgical stage, removal of the allograft and reconstruction with a split-thickness skin graft (STSG) or Integra® (Lifesciences Corp., Plainsboro, NJ, USA) and STSG.Results.A total of 22 patients were analyzed, 15 of them women (68.18%) with an average age of 72.5 years. The average surface area of the chronic ulcers was 111.76 cm2. The etiology of the ulcers was vascular in 12 patients (54.54%) and post-traumatic in 10 patients (45.45%). In 20 patients (90.9%) the acceptance of the cadaveric skin graft was achieved; in 18 cases the graft was taken 100% and in 2 cases 50%. The allograft was applied as a temporary skin substitute for the preparation of the receptor bed. All patients showed a decrease in the inflammatory process, exudate and pain.Conclusions.In our experience, cadaveric skin graft is a valid option for the treatment of chronic ulcers resistant to non-surgical treatment.

ABSTRACT

In the surgical suture, the implanted thread can be a source of microbial contamination. Implanted materials are frequently described as being substrates prone for biofilm development provoking surgical site infections. Treatment of postsurgical wounds with different topical antimicrobial agents is a current practice applied to every patient. However, to date, there is little evidence on the efficacy of different antiseptic treatments on suture materials in preventing environmental or skin bacterial adhesion and further infection. Here, the authors compared the ability of an aerosol formulation of silver sulfadiazine, vitamin A, and lidocaine (AF-SSD) and of two of the most frequently used topical treatments, povidone-iodine and ethanol, in eradicating or controlling the microbial contamination of suture threads in patients who have undergone clean surgeries. Postsurgical suture threads treated with AF-SSD showed a significantly reduced proportion of contaminated samples containing viable microbial cells compared with those treated with povidone-iodine or ethanol. Furthermore, those samples that were positive for bacterial growth showed a lesser number of viable cells in AF-SSD-treated sutures than those treated with povidone-iodine or ethanol. Confocal laser scanning microscopy showed that AF-SSD-treated postsurgical sutures presented significantly less attached microbial cells than povidone-iodine and ethanol, with scarce observable microbial cells on the surface of the suture. Taken together, the results suggest that treatment with AF-SSD is more effective than the other two antiseptics, and there is a potential for improvement in reducing the microbial burden of implanted materials such as the suture thread.

ABSTRACT

Introducción y Objetivo. La cicatrización es un proceso complejo que involucra diferentes tipos celulares y fases de inflamación, proliferación, remodelación y reparación. Cada una está caracterizada por eventos bioquímicos específicos y células características, conduciendo a la regeneración del epitelio dañado. El presente estudio compara y evalúa 2 tratamientos de uso tópico en 2 cicatrices de un mismo paciente al que se le practicó cirugía estética con la finalidad de determinar si existen diferencias en cuanto a las características de las mismas. Particularmente, en la Cirugía Estética, se busca que el nuevo tejido producto del proceso cicatricial no se destaque de la piel circundante. Material y Método. Uno de los tratamientos utilizados fue la aplicación tópica de crema con sulfadiazina de plata, vitamina A y lidocaína, y el otro de una crema hidratante sin ningún principio activo añadido. Empleamos como indicadores para la evaluación los parámetros de medición de la superficie, calidad de la misma (Escala de Vancouver para cicatrices) y percepción del paciente (Escala de Evaluación Objetiva de Paciente y Observador). Resultados. Indican que la utilización de un tratamiento tópico con sulfadiazina de plata, vitamina A y lidocaína acelera la reducción del tamaño de la herida, mejora la calidad de la cicatriz y favorece la percepción positiva por parte del paciente en comparación con aquellas cicatrices tratadas tópicamente con una crema hidratante sin principios activos. Conclusiones. El uso tópico de crema con sulfadiazina de plata, vitamina A y lidocaína constituye una opción terapéutica que mejora el resultado final tanto estético como funcional de las cicatrices postquirúrgicas en Cirugía Estética (AU)


Background and Objective. Healing is a complex process that involves different cell types and phases of inflammation, proliferation, remodeling and repair. Each one is characterized by specific biochemical events and characteristic cell leading to the regeneration of damaged epithelium. This study compares and evaluates 2 treatments, applied topically in 2 post-reconstructive aesthetic surgery scars of the same patient with the purpose of determining if there are differences in the characteristics of the same. Particularly in Aesthetic Surgery, it is sought that the new tissue does not stand out from the surrounding skin. Methods. One of the treatments consisted in applying topically a cream with silver sulfadiazine, vitamin A and lidocaine, and the other a moisturizer without any active ingredient. Linear and superficial scar measurement, scar severity (Vancouver Scar Scale) and patient perception (Patient and Observer Scar Assessment Scale) were used as parameters to evaluate the results. Results. They show that the use of a topical treatment with a cream containing silver sulfadiazine, vitamin A and lidocaine decreases the wound size faster, improves scar quality and increases patients positive perception in comparison with those scars treated topically with a cream without active ingredients. Conclusions. The topical use of a cream containing silver sulfadiazine, vitamin A and lidocaine is a therapeutic option that improves the final aesthetic and functional result of post-surgical scars (AU)

ABSTRACT

Introducción. La inyección de silicona líquida y sus complicaciones a largo plazo fueron descriptas por Winer en 1964. Los siliconomas representan la reacción infl amatoria mediada por el organismo en respuesta a la inyección de un cuerpo extraño, produciendo complicaciones tales como deformidad, dolor y celulitis. Material y método. Se presenta el caso de un paciente de sexo masculino de 64 años de edad con antecedente de inyección de silicona líquida en región glútea en el año 2000. Evolucionó con deformidad en glúteos y ambas regiones trocantéricas asociadas a dolor en posición supina y sedestación. Se trató mediante dermolipectomía de las regiones comprometidas asociado a lipotransferencia glútea en el plano profundo del tejido celular subcutáneo en dos tiempos quirúrgicos. Resultados. La remisión del dolor fue del 100% a los 7 días con escaso requerimiento de analgésicos vía oral. Se observó mejoría de la calidad de la piel y menor congestión tisular. Además, se observó una recuperación del contorno corporal con atenuación de la celulitis y deformidad lateral. A los 8 meses posoperatorios los resultados estéticos fueron satisfactorios. Conclusión. El tratamiento quirúrgico resectivo de las regiones comprometidas por la disgregación de silicona líquida más lipotransferencia corregiría las complicaciones tanto estéticas (deformidad anatómica, celulitis) y funcionales disminuyendo el dolor vinculado a la presencia de estos cuerpos extraños, con mejoría en la calidad de los tejidos lesionados.


Background. Silicone injection and its further complications were fi rst reported by Winner in the 1960s. Siliconomas represent the chronic infl ammatory reaction of the organism in response to the presence of a foreign body. The latter complications such as deformity, cellulitis and pain are often seen and very diffi cult to treat. Material and method. A case of a 64 year-old male with medical history of silicone injection in gluteal region in year 2000. At physical examination, he had deformity of the gluteal and trochanteric regions associated with pain. The surgical strategy consisted in dermolipectomy of the thights and buttocks associating mechanical liposuction of the damaged region with posterior lipofi llingin the deep cellular tissue in both gluteal zones. The fat grafting was done in to separated sessions. Results. Pain decreased in 100% at 7 days postoperative with a low consume of analgesics. There was an improvement in skin quality with less local tissue congestion. Cellulitis and lateral deformity of tights were well-treated with surgery. With a follow-up of 8 months, cosmetic and functional results were satisfactory. Conclusion. The association of dermolipectomy with mechanical liposuction and lipofi lling may be a good surgical strategy in the correction of silicone injection sequelae improving not only the aesthetic results but also the remission of pain providing a better quality of life in these patients.

ABSTRACT

La reconstrucción de la región periolécranon es compleja, ya que requiere tejidos que tengan suficiente elasticidad y resistencia y que permitan una rápida recuperación. Cuando la etiología es tumoral, se debe tener en cuenta la exéresis completa de la lesión, la conservación de la funcionalidad del miembro y el aspecto estético, respetando ese orden. Presentamos la evolución de una paciente con un sarcoma de partes blandas en la región del codo que, tras su extirpación en bloque, se reconstruyó con un colgajo pediculado braquial lateral de flujo inverso, y que posteriormente, para mejorar su aspecto estético, se realizó lipoaspiración del colgajo y relleno graso de la zona dadora


The reconstruction of the peri-olecranon region is complex, requiring tissues with enough elasticity and strength, to ensure a rapid recovery. When the etiology is tumoral, complete excision of the lesion, the mobility of the limb, and the aesthetics should be taken into account, in that order. We present the evolution of a patient with soft tissue sarcoma in the elbow region, which was removed, and the elbow was reconstructed with a lateral brachial pedicle flap withreverse flow. Afterwards, to improve their aesthetic appearance, liposuction of the flap was performed, filling the donor site with fat.

ABSTRACT

A prospective observational study of central venous catheters (CVC) was carried out in order to determine if a CVC inserted near an open burn wound increases catheter infection risk in burned patients. The study was carried out during a 12-month period (1998-1999) at the Benaim Foundation's Burn Unit in Buenos Aires (C.E.P.A.Q.). Eighty-three CVCs were inserted in 20 burned patients during the study period. Twenty-six catheters were inserted near an open wound (NOW) and 57 far from an open wound (FOW). NOW CVCs were considered when 25 cm2 surrounding the catheter's insertion site overlapped the wound. Colonization rates were 84% (22/26 CVCs) in those inserted NOW and 47% (27/57 CVCs) in FOW (P = 0.001). Colonization relative risk of NOW-CVCs was 1.79 (95% confidence interval, 1.3-2.46). Bacteremia rates were 27% (7/26 CVCs) in CVCs inserted NOW and 6% (3/57 CVCs) in FOW (P = 0.004). Bacteremic risk of NOW-CVCs was 5.12 (95% confidence interval, 1.44-18.22). Colonization rates were higher and sooner in NOW-CVCs than in FOW-CVCs. We suggest that insertion of catheters near an open burn wound should be avoided and, if inevitable, should not be left in place for period exceeding 3 days.
