ABSTRACT

Ring avulsions continue to be a challenge in reconstructive surgery. We conducted a retrospective study and reviewed all Urbaniak-Kay type IV degloving injuries replanted at our institution between 2011 and 2018. A systematic review of the literature was also conducted to assess the survival rates, functional, and sensibility outcomes. The results of our systematic review outline a survival rate of 79.50% (101/127). With 1 artery being repaired, 79% of the fingers survived, a value that increased to 87.50% when 2 arteries were anastomosed (P = 0.484). Statistically significant differences (P < 0.001) were found when comparing the survival rates of the fingers with 2 or more veins repaired (87%) with those with only 1 vein anastomosed (51.90%). In terms of nerve reconstruction, there was a significant difference (P < 0.001) with the 2-point discrimination test in favor of the reconstructed group when nerve reparation was done (10.80 mm ± 2.95 mm) versus when digital nerves were not repaired (15.25 mm ± 0.50 mm). Fingers after secondary procedures did not obtain better mobility. The mean total active motion in nonreoperated fingers was 221 degrees (195-270 degrees), whereas the total active motion in the cases who received secondary surgeries was 152 degrees (110-195 degrees), with statistically significant differences (P = 0.02). Therefore, we recommend attempting replantation of degloved fingers. All efforts must be done to carry out 2 vein anastomoses, and our results strongly recommend attempting at least some kind of nerve reconstruction. Secondary surgeries should be reserved for selected cases only, because of the extensive scarring in this kind of injuries. Early mobilization protocols must be encouraged to achieve a good functional result.

ABSTRACT

Autologous flap breast reconstruction is an established technique that carries a risk of vascular failure. We evaluated the safety of salvaging impending venous congestion by using the cephalic vein for supercharging autologous abdominal flaps. Our main outcome measures were flap survival, triggering or impairing lymphedema as measured by the physician or reported by the patient, and scar severity as measured by the Vancouver scar scale. We were able to save 100% of the flaps, but could not find any statistical association with or without increased lymphedema before and after the procedure. One patient reported that lymphedema worsened. The patients accepted the scars (mean Vancouver scar scale score, 5.7). In sum, using the cephalic vein to improve venous drainage of autologous breast reconstruction was safe and did not trigger or impair lymphedema, but scarring in the upper arm was unavoidable.

ABSTRACT

The aim of this work is to compare disabilities of the upper limb before and after hand allograft transplantation (HAT), and to describe the side effects of immunosuppressive (IS) agents given to recipients of hand allografts. Clinical cases of HAT published between 1999 and 2011 in English, French, or German were reviewed systematically, with emphasis on comparing disabilities of the arm, shoulder and hand (DASH) scores before and after transplantation. Duration of ischemia, extent of amputation, and time since amputation were evaluated for their effect on intrinsic musculature function. Infectious, metabolic, and oncological complications because of IS therapy were recorded. Twenty-eight patients were reported in 56 clinical manuscripts. Among these patients, disabilities of the upper limb dropped by a mean of 27.6 (±19.04) points on the DASH score after HAT (P = 0.005). Lower DASH scores (P = 0.036) were recorded after secondary surgery on hand allografts. The presence of intrinsic muscle function was observed in 57% of the recipients. Duration of ischemia, extent of transplantation, and time since amputation were not associated statistically with the return of intrinsic musculature function. Three grafts were lost to follow-up because of noncompliance with immunosuppression, rejection, and arterial thrombosis, respectively. Fifty-two complications caused by IS agents were reported, and they were successfully managed medically or surgically. HAT recipients showed notable functional gains, but most complications resulted from the IS protocols.

ABSTRACT

Acute rejection (AR) of human hand allografts (HHAs) may carry a risk of graft loss and leads to the need for immunosuppressive treatment. The literature on HHAs was reviewed to determine and evaluate the factors that trigger AR of HHAs. Clinical case reports of hand allograft transplantation published between 1999 and 2011 in English, French, or German were reviewed systematically. The number of AR episodes was the main outcome measure. Sixty-eight episodes of AR were described in 28 recipients. Calcineurin inhibitor-based maintenance regimens were associated with significantly fewer AR episodes than non-calcineurin inhibitor-based regimens (mean 1.9 vs 3.2; P = 0.018). In recipients who experienced cytomegalovirus infection, the mean number of episodes of AR was 4, whereas in those who did not experience cytomegalovirus infection it was 2.25 (P = 0.024). The planning of hand allograft transplantation should take these factors into account to minimize the risk of AR.

ABSTRACT

INTRODUCCIÓN Y OBJETIVO: El desbridamiento enzimático ha demostrado ser eficaz y rápido en su aplicación sobre quemaduras, a la vez que conservador con el tejido sano. Su uso sobre quemaduras inferiores al 15% ha mostrado reducir la cantidad de injertos, el sangrado y las escarotomías quirúrgicas. El objetivo de este estudio es comparar 2 grupos de pacientes grandes quemados, uno tratado mediante desbridamiento enzimático frente a otro tratado mediante tratamiento estándar, y su impacto en la estancia hospitalaria, necesidades de escarotomías, tiempo hasta desbridamiento, uso de hemoderivados y cantidad de cirugías durante el ingreso. MATERIAL Y MÉTODO: Estudio de cohortes retrospectivas con 197 pacientes (SCQ 20-50%), mayores de 18 años, tratados entre 2012 y 2017, con 2 grupos: 32 pacientes tratados con Nexobrid® para el desbridamiento enzimático, y 165 pacientes en el grupo control con desbridamiento tangencial convencional. Ambos homogéneos para SCQ, edad, sexo, mecanismo de lesión y comorbilidades. RESULTADOS: La edad media fue de 48.4 ± 19.4 años, con una SCQ media de 29.5 ± 9.4%. Observamos disminución del tiempo hasta el inicio del desbridamiento de la quemadura (5.1 ± 4.9 días en el grupo control frente a 0.8±0.9 en el grupo de desbridamiento enzimático, p < 0.05). El grupo de Nexobrid® presentó una reducción de la cantidad de tiempos quirúrgicos durante su ingreso, siendo de 1.9±2.0 frente a 2.6±2.1 en el grupo control. El uso de hemoderivados se redujo en un 95% durante el desbridamiento. La necesidad de escarotomías se redujo un 60%. Finalmente, el grupo de Nexobrid® tuvo un 36% menos de estancia en la Unidad de Quemados Críticos, con diferencias estadísticamente significativas. CONCLUSIONES: La aplicación precoz del desbridamiento enzimático en grandes quemados (20-50% SCQ), permite la escarectomía completa del paciente reduciendo la necesidad de hemoderivados, el número de tiempos quirúrgicos, las escarotomías y la estancia en la unidad de cuidados intensivos


BACKGROUND AND OBJECTIVE: Use of enzymatic debridement has demonstrated be fast and efficient after its application over burn wounds, being more delicate over healthy tissue. Its use in burns under 15% TBSA has shown less grafting procedures, bleeding and surgical escharotomies. The aim of this study was compare 2 groups of major burns; one treated by enzymatic debridement and other treated by standard of care. Length of stay, escharotomies, time until debridement, use of blood packs and number of surgeries during hospitalization were evaluated. METHODS: A retrospective cohort study was designed with 197 patients (TBSA 20-50%), older than 18 years old, treated between 2012 and 2017, and divided in 2 groups: 32 patients were debrided using Nexobrid®, and 165 patients were included in the control group. Both groups were homogeneous for TBSA, age, gender, mechanism and comorbidities index. RESULTS: Mean age was 48.4±19.4 years, with a 29.5±9.4% of TBSA. A reduction of the number of days until the burns debridement were found, with 5.1±4.9 in the control group and 0.8±0.9 days in the enzymatic debridement group (p < 0.05). The number of surgeries during the hospitalization were less in the Nexobrid® group, with a reduction of 2.6±2.1 surgeries to 1.9±2.0. The number of blood packs was a 95% lower in the enzymatic debridement, and a 60% less escharotomies were observed. Finally, a shorter length of stay in the intensive care unit were found in the Nexobrid® group, with 36% less days, this difference were statistically significant. CONCLUSIONS: Early application of enzymatic debridement in major burns (20-50% TBSA) allows a complete removal of eschar reducing the blood packs use, number of surgeries, escharotomies and length of stay in the intensive care unit

ABSTRACT

INTRODUCTION: The estimation of the caloric requirements of the burn patient is based on the measurement of his resting energy expenditure (REE) via indirect calorimetry, which is not available in all Burn Units, or its estimation by means of predictive equations. GOALS: we analyze the history and state of art of the use of REE predictive equations in burn patients, and determine their validity. METHODS: bibliographic review of the studies and reviews written in English and Spanish between 1989 and 2013. RESULTS: More than 190 equations have been designed to estimate energy expenditure. These equations can be imprecise because they are based on measurements with a heterogeneous methodology and in heterogeneous groups. We describe the different parameters that are used in the different equations (stress and activity factors, total burn surface area, post-burn day, lean body mass), the influence of age in the calculation of the caloric requirements, and the most commonly used equations nowadays. We also describe the articles that evaluate the accuracy of the predictive equations when compared to REE indirect calorimetry measurements. CONCLUSIONS: Predictive equations are not precise in general in the burn patient. Until more accurate predictive equations are developed, we recommend calculation of the nutritional requirements in burn patients based on the energy expenditure measurement via indirect calorimetry.


Introducción: La valoración de las necesidades calóricas del paciente quemado se ha basado en la medición del gasto energético en reposo (GER) mediante calorimetría indirecta, no siempre disponible en las unidades de quemados, o en su estimación mediante el uso de ecuaciones predictivas. Objetivos: analizar la historia y estado del arte del uso de las ecuaciones predictivas de GER en el paciente quemado crítico, y determinar su validez. Métodos: revisión bibliográfica de estudios y revisiones en español y en inglés entre 1989 y 2013. Resultados: Se han diseñado más de 190 ecuaciones para estimar el gasto energético que pueden ser imprecisas por estar basadas en mediciones con metodología heterogénea y en grupos heterogéneos. Describimos los distintos parámetros que aplican las distintas fórmulas predictivas (factores de estrés y de actividad, superficie corporal quemada, tiempo desde la lesión, masa corporal magra), la influencia de la edad en el cálculo de las necesidades calóricas y las fórmulas más utilizadas en el momento actual. También describimos los artículos que evalúan exactitud de las fórmulas cuando se comparan con mediciones mediante calorimetría indirecta. Conclusiones: Las ecuaciones predictivas son poco precisas en general en el paciente quemado. Hasta que se desarrollen ecuaciones predictivas más precisas, recomendamos calcular los requerimientos nutricionales de los pacientes quemados basándose en la medición del gasto energético por calorimetría indirecta.

ABSTRACT

Introducción y Objetivo: Los trasplantes de tejidos compuestos sufren rechazo crónico modulado entre otros factores por citoquinas. El quimerismo reverso o quimerismo del aloinjerto se define como la repoblación del tejido trasplantado por células circulantes del receptor. Plerixafor produce la movilización de células madre de médula ósea CD34+ hacia la sangre periférica. El objetivo del estudio fue conocer los mecanismos moleculares que intervienen en el rechazo crónico y el quimerismo reverso tras la administración de plerixafor. Material y Método: Realizamos 16 trasplantes osteomusculares heterotópicos de pata posterior entre ratas Brown-Norway hembra y Wistar Lewis macho bajo inmunosupresión subterapéutica con tacrólimus. Establecimos 2 grupos de estudio según la administración postoperatoria de plerixafor. Transcurridas 9 semanas estudiamos la expresión de citoquinas y el infiltrado leucocitario en distintas localizaciones musculares, así como el grado de rechazo crónico y porcentaje de quimerismo reverso en diferentes tejidos del aloinjerto. Resultados: Encontramos diferencias estadísticas en la expresión de factor estimulante de colonias granulocíticas e interleucina 12 a nivel de los tercios medio y distal del aloinjerto, y de interleucina 6 a nivel del tercio medio del aloinjerto. La intensidad del infiltrado leucocitario fue mayor en el grupo que no recibió plerixafor. Ambos grupos desarrollaron rechazo crónico y pudimos observar la aparición de quimerismo reverso. Sin embargo no observamos diferencias significativas en el infiltrado leucocitario, el rechazo crónico ni el quimerismo reverso. Conclusiones: La movilización de células madre de médula ósea CD34+ se asoció con una menor expresión de factor estimulante de colonias granulocíticas, interleucina 6 e interleucina 12. Estos hallazgos contribuyen a elucidar los mecanismos moleculares que podrían conducir a la creación de quimeras en el aloinjerto


Background and Objective: Vascularized composite allotransplantation suffer chronic rejection modulated by cytokines. Reverse chimerism or allograft chimerism is defined as the repopulation of the transplanted tissue by circulating cells of the recipient. Plerixafor mobilizes CD34+ bone marrow stem cells to the peripheral blood. The aim of the study was to know the molecular mechanisms involved in chronic rejection and reverse chimerism after plerixafor administration. Methods: Sixteen heterotopic osteomuscular hindlimb transplants were performed between female Brown-Norway rats as donors and male Wistar Lewis rats as recipients under subtherapeutic immunosuppression with tacrolimus. Two groups were established according to the postoperative administration of plerixafor. After 9 weeks, expression of cytokines and leukocyte infiltration were studied in different muscle locations, as well as the degree of chronic rejection and percentage of reverse chimerism in different tissues of the allograft. Results: Statistical differences were found in granulocyte colony stimulating factor and interleukin 12 expression at middle and distal allograft thirds, and interleukin 6 expression at middle allograft third. The intensity of leukocyte infiltration was greater in the group that did not receive plerixafor. Both groups developed chronic rejection and the appearance of reverse chimerism could be observed. However, no significant differences were observed in leukocyte infiltration, chronic rejection or reverse chimerism. Conclusions: The mobilization of CD34+ bone marrow stem cells was associated with a lower expression of granulocytic colony stimulating factor, interleukin 6 and interleukin 12. These findings contribute to elucidate the molecular mechanisms that could lead to the creation of chimeras in the allograft

ABSTRACT

Introducción y Objetivo: El desbridamiento enzimático con Nexo-brid(R), concentrado de enzimas proteolíticas enriquecidas en bromelaína, supone un avance terapéutico importante. El objetivo de este trabajo es realizar un análisis económico del tratamiento de quemaduras térmicas con Nexobrid(R), investigando los determinantes del coste. Material y Método: Analizamos retrospectivamente los recursos utilizados en el tratamiento mediante desbridamiento enzimático con Nexobrid(R) de las heridas por quemadura térmica de espesor parcial superficial/profundo y completo, de los pacientes adultos ingresados consecutivamente en nuestro hospital entre 2014 y 2016. Investigamos la participación de cada recurso en el coste total para algunos subgrupos de pacientes. Resultados: Estudiamos a 71 pacientes con edad media de 45.4 años; el 73.2% varones. Las lesiones fueron en un 64.8% por llama el 77.5% fueron quemaduras dérmicas profundas y la superficie corporal total afectada fue ≤10% en el 70.4%. El coste medio estimado por paciente fue de 20.844€ (rango: 2.192€ - 145.198€), correspondiendo el 68,1% a la estancia en la Unidad de Quemados Críticos y en hospitalización convencional y el 13.9% al uso de Nexobrid(R). El coste medio de las quemaduras subdérmicas fue significativamente superior al de las dérmicas profundas (p=0.0004) y dérmicas superficiales (p=0.013). El porcentaje de superficie corporal total quemada marcó una diferencia significativa del coste (p<0.0001), observando una correlación importante (R2 = 0.77) con la estancia hospitalaria total. Conclusiones: La estancia hospitalaria en Unidad de Quemados Críticos y en hospitalización convencional constituye el principal determinante del coste del tratamiento de las quemaduras térmicas de espesor parcial superficial/profundo y completo mediante desbridamiento enzimático (48,7% y 19,4% del total, respectivamente); Nexobrid(R)contribuye sólo con un 13,9% del total. Asimismo, el porcentaje de superficie corporal total quemada muestra una fuerte correlación con la estancia hospitalaria


Background and Objective: Enzymatic debridement with Nexo-brid(R), a concentrate of proteolytic enzymes enriched in bromelain, represents an important therapeutic breakthrough. Our aim is to carry out an economic analysis of the treatment of thermal burns with Nexobrid(R), researching the cost determinants. Methods: We analyzed retrospectively the resources used in the treatment by enzymatic debridement with Nexobrid(R) of wounds by thermal burn of superficial/deep partial and full-thickness, of the adult patients admitted consecutively in our hospital (2014-2016). Participation of each resource in total cost was analyzed for some patient subgroups. Results: Seventy one patients were analyzed: age: 45.4 years; men: 73.2%; flame wound: 64.8%; full-thickness burn: 77.5%; Total Body Surface Area ≤10%: 70.4%. Average cost per patient was estimated in €20.844 (range: €2.192-€145.198); 68.1% was associated to length of Critical Burn Unit and conventional hospital stay. Cost of full-thickness burns was significantly higher than that of the superficial (p=0.013) and deep partial ones (p=0.0004). Total Body Surface Area leaded a significant cost difference (p<0.0001), showing a high correlation (R2=0.77) with the total hospital length of stay. Conclusions: Hospital length of stay (Critical Burn Unit and conventional hospital) is the main cost determinant of the treatment of thermal burns of superficial/deep partial and full-thickness with enzymatic debridement (48.7% and 19.4%, respectively); Nexobrid(R) contributes only with 13.9% of total cost. Likewise, total body surface area shows a strong correlation with length of stay

ABSTRACT

Introducción y Objetivo. En los últimos años se han publicado resultados que demuestran un desbridamiento enzimático rápido, eficaz y específico de tejidos quemados con el uso de Nexobrid(R) (Mediwound, Alemania), producto compuesto por un concentrado de enzimas proteolíticas enriquecidas con bromelaína. En este estudio comparamos el uso de Nexobrid(R) como desbridante enzimático frente a un Grupo Control con tratamiento estándar, con el objetivo de evaluar; en función de la superficie corporal quemada (SCQ), la cantidad de intervenciones quirúrgicas realizadas, la colonización del lecho quirúrgico, la necesidad de escarotomías, así como los requerimientos transfusionales de los pacientes tratados. Material y Método. Estudio retrospectivo con 65 pacientes, edad media de 46.87 años, tratados con Nexobrid(R) entre septiembre de 2015 y diciembre de 2016. Comparamos con un grupo control de 177 pacientes, edad media de 48.24 años, intervenidos mediante desbridamiento tangencial desde enero a diciembre de 2014. El Grupo Control presenta unas características homogéneas a las del Grupo Nexobrid(R). Ambos grupos fueron estratificados en función de su SCQ mayor o menor del 15%. Resultados. Encontramos diferencias estadísticamente significativas (p <0.01) con un menor número de días desde la quemadura y el ingreso hasta la cirugía para el Grupo Nexobrid(R) independientemente de la SCQ. Obtuvimos diferencias estadísticamente significativas para la cantidad de cirugías (p <0.01) en el subgrupo de SCQ <15%. Evaluamos la colonización sin obtener diferencias estadísticamente significativas entre los grupos. El número de escarotomías en el Grupo Nexobrid(R) fue significativamente menor que en el Grupo Control para las poblaciones con SCQ ≥15%. Los requerimientos transfusionales fueron menores en el Grupo Nexobrid(R) frente al Grupo Control en los pacientes con SCQ ≥ 15% (p <0.05). Conclusiones. Nexobrid(R) permite reducir el número de cirugías y el tiempo hasta el primer desbridamiento sin aumentar la tasa de colonización respecto al Grupo Control. El desbridamiento enzimático precoz reduce la necesidad de escarotomías en pacientes con SCQ ≥15%. Finalmente, reduce la necesidad de transfusión sanguínea en pacientes con SCQ mayor del 15% (AU)


Background and Objective. During the last years, results have been published demonstrating fast, efficient and specific enzymatic debridement of burned tissues with the use of a concentrate of proteolytic enzymes enriched with bromelain (Nexobrid(R), Mediwound, Germany). In this study we compare the use of Nexobrid(R) against a Control Group with standard treatment, in order to evaluate; the number of surgical procedures performed, the colonization of the surgical bed, the need for scarotomies, as well as the number of transfusions of the treated patients according to the total burned surface area (TBSA). Methods. We conduct a retrospective study evaluating 65 patients (mean age 46.87 years) treated with Nexobrid(R) between September 2015 and December 2016. We compare this population with a control group of 177 patients (mean age 48.24 years) treated with tangential excision from January to December 2014. The Control Group was homogeneous to Nexobrid(R) Group. Both groups were stratified according to their TBSA in 2 groups: more or less than 15%. Results. We found lesser number of days from burn and hospital admission to the first debridement for the Nexobrid(R) Group regardless of the burned body surface. Statistically significant differences were obtained for the number of surgeries (p <0.01) in the subgroup with <15% TBSA. We evaluated the colonization without obtaining statistically significant differences between the groups. The number of scarotomies carried out in the Nexobrid(R) Group was significantly lower than in the Control Group when comparing the populations with ≥15% TSBA. The transfusion requirements were lower in the Nexobrid(R) Group compared to the Control Group in patients with ≥15% TBSA (p <0.05). Conclusions. The use of Nexobrid(R) allows reducing the number of surgeries and the time elapsed to first debridement without increasing the rate of colonization when compared to the Control Group. Early enzymatic debridement reduces the need for scarotomies in ≥15% TBSA patients. The use of Nexobrid (R) reduces the need for blood transfusion in patients with ≥15% TBSA (AU)

ABSTRACT

El reimplante de pabellón auricular tras una avulsión traumática permite restaurar el segmento amputado con buenos resultados. El procedimiento es técnicamente demandante debido al pequeño calibre de los vasos a anastomosar y a la lesión por avulsión que suele presentar la íntima, no siendo posible restablecer el drenaje venoso en todos los pacientes. La congestión venosa postoperatoria es la complicación más frecuente de los reimplantes auriculares. Existen diversos protocolos postoperatorios de anticoagulación/antiagregación, sin que haya evidencia a favor de la superioridad de ninguno de ellos. Ante la congestión venosa del segmento reimplantado, las medidas de rescate incluyen el empleo de hirudo medicinalis y los sangrados pautados tras el rascado de una zona cruenta. Cuando las cifras de hemoglobina tras las medidas de rescate descienden fuera del rango normal suele ser necesaria la transfusión de concentrados de hematíes, una medida habitual en este tipo de procedimiento. Presentamos un caso de reimplante auricular donde no pudo restablecerse el drenaje venoso intraoperatoriamente, así como el protocolo de sangrado utilizado tras la congestión venosa del mismo. Además discutimos las diferentes medidas que suplen el drenaje venoso en los reimplantes de pabellón auricular (AU)


Ear replantation after traumatic avulsion amputation restores the amputee segment with good results. This demanding procedure presents a significant challenge due to the small vessels size and the avulsion injury that the amputated pinna frequently presents, not being possible to restore venous outflow in all patients. Postoperative venous congestion is the most common complication of ear replantation. Regardless the various anticoagulation/antiagregation therapeutic options, there is no evidence that demonstrates the superiority of neither of them. In case of venous congestion an alternative mean of drainage is mandatory, including medicinal leech therapy and blood drainage through small incisions. In these cases, blood transfusions are a common measure in this kind of procedures, usually necessary to maintain hemoglobin levels within normal. We present a case of ear replantation in which venous drainage could not be restored, its postoperative course and the bleeding drainage protocol used after venous congestion. In addition, we discuss the various measures that supplement venous drainage in pinna replantation (AU)

ABSTRACT

Los tumores glómicos malignos son neoplasias poco frecuentes del cuerpo glómico mioarterial. Presentamos un caso de tumor glómico maligno en mano derecha en mujer de 72 años. La resonancia magnética identificó tumoración de partes blandas de predominio subcutáneo, en el segundo dedo de la mano, con áreas más profundas que contactaban con los tendones flexores del dedo, el músculo primer interóseo dorsal y los huesos subyacentes. El estudio de extensión no evidenció enfermedad macroscópica maligna. Histológicamente el tumor tenía arquitectura plexiforme. Las células tumorales estaban en íntima relación con vasos de pequeño calibre, en ocasiones con tinción PAS positiva, con morfología fusiforme y focalmente epitelioide, atipia moderada y tasa mitótica de 4 mitosis en 10 campos de gran aumento, sin identificarse mitosis atípicas ni necrosis tumoral. Con técnicas de inmunohistoquímica se observó positividad difusa para actina de músculo liso y vimentina, con marcaje célula a célula de colágeno tipo IV y negatividad para CD34, caldesmon, desmina, queratinas y S100. Realizamos escisión quirúrgica amplia con márgenes negativos y se administró radioterapia adyuvante sobre la mano, sin evidencia de recidiva tumoral tras 9 meses de seguimiento. Presentamos también una revisión de la literatura sobre tumores glómicos malignos en miembro superior, así como el diagnóstico diferencial de este tipo de lesiones cuando se localizan en la piel y el tejido celular subcutáneo (AU)


Malignant glomus tumors are rare malignancies of the mioarterial glomus body. We report a case of a malignant glomus tumor located in the right hand of a 72 years old patient. Magnetic resonance imaging identified a soft tissue tumor of the second finger, with deeper areas in contact with the flexor tendons, the first dorsal interosseous muscle and underlying bones. The extension study showed no macroscopic malignant disease. Histologically the tumor had a plexiform architecture. Tumor cells were in close relationship with small vessels, sometimes with positive PAS staining, had a fusiform and focally epithelioid morphology with moderate atypia and a mitotic rate of 4 mitosis in 10 high magnification fields, without a typical mitosis and tumor necrosis. Diffuse positivity staining for vimentin and actins mooth muscle was observed immunohistochemically, with cell-to-cell labelty for IV collagen and negative for CD34, caldesmon, desmin, keratins and S100. Wide excision with negative margins was performed and adjuvant radiotherapy was administered on hand, with no evidence of tumor recurrence after 9 months follow up. Additionally, a review of the literature of malignant glomus tumors located in the upper limb, and the differential diagnosis of this type of tumors located in the skin and subcutaneous tissue were presented (AU)

ABSTRACT

Introducción y Objetivo. El tratamiento clásico de las quemaduras se basa en la eliminación precoz de la escara; sin embargo, el desbridamiento tangencial de las quemaduras mixtas y profundas retira tejidos dérmicos viables, obligando a la cobertura con autoinjertos. El desbridamiento enzimático con enzimas proteolíticos enriquecidos con Bromelaína (Nexobrid®) mantiene restos dérmicos que pueden permitir la reepitelización por sí misma de la quemadura. Evaluamos el uso en nuestra unidad de Nexobrid® (MediWound Ltd., Israel) en quemaduras mixtas y dérmicas profundas, valorando la capacidad de reepitelización tras su uso, la tasa de injerto en los pacientes tratados, y la aparición de cicatrización hipertrófica. Pacientes y Método. Evaluamos retrospectivamente 36 pacientes tratados con Nexobrid® entre enero de 2015 y febrero de 2016, 11 mujeres y 25 varones con una media de edad de 42.89 años. La superficie corporal quemada media fue del 7.47% y la diagnosticada como profunda del 6.42%.Todos los pacientes presentaron quemaduras profundas con necesidad de cirugía para su desbridamiento y cobertura con injertos. Resultados. Tras el desbridamiento enzimático solo el 36.1% de los pacientes (13 de 36) requirió cobertura con injertos (p < 0.001).La superficie injertada fue tan solo del 2.67% frente al 4.98% que fue desbridada enzimáticamente (p < 0.001). A pesar de que el tiempo hasta la epitelización total de las quemaduras se alargó hasta los 25.69 días, tan solo un 11.1% de los pacientes desarrolló cicatriz hipertrófica. Conclusiones. Nexobrid® permite el desbridamiento completo de las quemaduras mixtas y dérmicas profundas disminuyendo el porcentaje de pacientes que requieren autoinjertos y la superficie injertada, con bajas tasas de cicatrización hipertrófica (AU)


Background and Objective. Early burn scar removal is the standard of care for burn patients; excisional debridement, however, often leads to excision of dermal remnants, making autografting unavoidable. Enzymatic debridement with proteolytic enzymes enriched in Bromelain (Nexobrid®) leaves these dermal remnants to allow spontaneous healing of partial thickness burns. This study evaluates if Nexobrid® (MediWound Ltd., Israel) reduces the need for surgery and autografting in intermediate and deepdermal burns, the reduction in the excised and grafted area, and the development of hypertrophic scarring. Patients and Methods. We conduct a prospective study between January 2015 and February 2016 evaluating 36 patients (11 females, 25 males) whose mean age was 42.89, with burns covering a mean of 7.47% of their total body surface area (6.42% deep burns). All patients would need excision and autografting as their previous standard of care. Results. After enzymatic debridement, only 13 patients (36.1%) needed surgery (p < 0.001). The area of burns excised and grafted was reduced (2.67% vs. 4.98% p < 0.001). Since wound closure was delayed until 25.69 days, only 11.1% of the patients developed hypertrophic scars. Conclusions. Nexobrid® allows scar removal in deep-dermal and intermediate burns, reducing the need of surgery and the grafted body surface area, while achieving good scars (AU)

ABSTRACT

Introducción: La valoración de las necesidades calóricas del paciente quemado se ha basado en la medición del gasto energético en reposo (GER) mediante calorimetría indirecta, no siempre disponible en las unidades de quemados, o en su estimación mediante el uso de ecuaciones predictivas. Objetivos: analizar la historia y estado del arte del uso de las ecuaciones predictivas de GER en el paciente quemado crítico, y determinar su validez. Métodos: revisión bibliográfica de estudios y revisiones en español y en inglés entre 1989 y 2013. Resultados: Se han diseñado más de 190 ecuaciones para estimar el gasto energético que pueden ser imprecisas por estar basadas en mediciones con metodología heterogénea y en grupos heterogéneos. Describimos los distintos parámetros que aplican las distintas fórmulas predictivas (factores de estrés y de actividad, superficie corporal quemada, tiempo desde la lesión, masa corporal magra), la influencia de la edad en el cálculo de las necesidades caló- ricas y las fórmulas más utilizadas en el momento actual. También describimos los artículos que evalúan exactitud de las fórmulas cuando se comparan con mediciones mediante calorimetría indirecta. Conclusiones: Las ecuaciones predictivas son poco precisas en general en el paciente quemado. Hasta que se desarrollen ecuaciones predictivas más precisas, recomendamos calcular los requerimientos nutricionales de los pacientes quemados basándose en la medición del gasto energético por calorimetría indirecta (AU)


Introduction: The estimation of the caloric requirements of the burn patient is based on the measurement of his resting energy expenditure (REE) via indirect calorimetry, which is not available in all Burn Units, or its estimation by means of predictive equations. Goals: we analyze the history and state of art of the use of REE predictive equations in burn patients, and determine their validity. Methods: bibliographic review of the studies and reviews written in English and Spanish between 1989 and 2013. Results: More than 190 equations have been designed to estimate energy expenditure. These equations can be imprecise because they are based on measurements with a heterogeneous methodology and in heterogeneous groups. We describe the different parameters that are used in the different equations (stress and activity factors, total burn surface area, post-burn day, lean body mass), the influence of age in the calculation of the caloric requirements, and the most commonly used equations nowadays. We also describe the articles that evaluate the accuracy of the predictive equations when compared to REE indirect calorimetry measurements. Conclusions: Predictive equations are not precise in general in the burn patient. Until more accurate predictive equations are developed, we recommend calculation of the nutritional requirements in burn patients based on the energy expenditure measurement via indirect calorimetry (AU)
