ABSTRACT

Subcutaneous fat necrosis of the newborn is a rare lobular panniculitis. It is characteristic of term or post-term neonates with a history of perinatal compromise or maternal gestational pathology. The cutaneous manifestations consist of erythematous and indurated subcutaneous plaques and nodules located over the dorsal region and the shoulders. Diagnosis is clinical and pathological. Histopathological findings include lobular panniculitis with a lymphohistiocytic inflammatory infiltrate with few neutrophils, fatty necrosis, deposition of radial needle-shaped crystals in the adipocytes, and possible calcification and hemorrhage. The cutaneous ultrasound shows hyperechoic and avascular subcutaneous cellular tissue and acoustic shadows may appear corresponding to calcifications. The clinical differential diagnosis includes sclerema neonatorum and post-corticosteroid panniculitis. Histologically crystal-forming panniculitis conditions are in the differential diagnosis. The disease is usually self-limited but complications such as hypercalcemia, hypoglycemia, hypertriglyceridemia, thrombocytopenia, and anemia may occur. Complications should be ruled out and treated at diagnosis and during follow-up. The most important complication is hypercalcemia.La necrosis grasa subcutánea neonatal es una paniculitis lobulillar infrecuente. Es característica de neonatos a término o postérmino con antecedentes de sufrimiento perinatal o patología gestacional materna. Las manifestaciones cutáneas consisten en placas y nódulos subcutáneos eritematosos e indurados localizados preferentemente en la región dorsal y los hombros. El diagnóstico es clínicopatológico. Los hallazgos histopatológicos comprenden una paniculitis lobulillar con un infiltrado inflamatorio linfohistiocitario con escasos neutrófilos, necrosis grasa, depósito de cristales radiados en los adipocitos y posibles focos de calcificación y hemorragia. En la ecografía cutánea se observa hiperecogenicidad y avascularización del tejido celular subcutáneo y pueden aparecer sombras acústicas posteriores que se correspondencon calcificaciones. El diagnóstico diferencial clínico se debe realizar con el escleredema neonatorum y la paniculitis postesteroidea, e histológicamente con las paniculitis con formación de cristales. La enfermedad suele ser autolimitada pero pueden aparecer complicaciones como la hipercalcemia, la hipoglucemia, la hipertrigliceridemia, latrombocitopenia y la anemia. Las complicaciones deben ser descartadas y tratadas en el diagnóstico y durante el seguimiento. La complicación másimportante es la hipercalcemia.

ABSTRACT

Aplasia cutis congenita (ACC) associated with fetus papyraceus is a rare subtype of aplasia cutis categorized as type V in Frieden's classification. It is characterized by stellate lesions in a symmetrical distribution over the trunk and proximal extremities. Conservative treatment is recommended, but there is not a well-defined therapeutic protocol. We report the case of a type V ACC in a preterm male newborn with lesions on the trunk and scalp successfully treated with topical 1% silver sulfadiazine and petrolatum gauze with an excellent evolution. This case associates a severe affectation of the scalp which represents a rare variant of type V ACC.

ABSTRACT

Successful management of toxic epidermal necrolysis (TEN) with tumor necrosis factor-α inhibitors has been described in adults, but few cases have been reported in children. To date, only four pediatric cases of TEN treated with infliximab and one with etanercept have been published. We present the case of an 8-year-old boy diagnosed with TEN induced by levetiracetam, successfully treated with etanercept, systemic corticosteroids, and intravenous immunoglobulin.

ABSTRACT

Chronic wounds have a high prevalence and wound care, treatment, and prevention consume large quantities of resources. Chronic wounds are a growing challenge for clinicians. A prospective randomized pilot study was conducted to assess the effectiveness in terms of reduction in area and safety of the combined use of negative-pressure wound therapy and nanocrystalline silver dressings as compared to negative pressure wound therapy (NPWT) alone in the management of outpatients with chronic wounds. A total of 17 patients were included in the study, 10 were treated with the combined method and 7 with NPWT. Patients were followed for 6 weeks, with a final assessment at 3 months. Clinical improvement, microbiologic data, and toxicity of silver were evaluated. The antibacterial effects of ionic silver together with the development of granulation tissue promoted by NPWT reduced significantly the median extension of the wound between weeks 3 and 6 of treatment. The combination with silver also reduced bacterial colonization with Pseudomonas aeruginosa and the bacterial load on the surface of the wound. The silver levels correlated positively with the extension of the wound, although in none of the patients' toxic levels were reached. The combination of NPWT with nanocrystalline silver dressings was safe and as effective as NPWT alone.

ABSTRACT

Introducción. Las técnicas endovasculares se utilizan cada vez con mayor frecuencia en el tratamiento de los aneurismas de aorta abdominal (AAA), para lo que es necesario emplear mayores dosis de radiación en los pacientes, tanto en el diagnóstico como en el procedimiento y su seguimiento posterior, que en el tratamiento quirúrgico convencional. Es imprescindible delimitar los niveles de referencia de dosis de radiación necesarios para la ejecución del procedimiento. Objetivo. Cuantificar la dosis total que reciben los pacientes sometidos a esta modalidad de tratamiento. Pacientes y métodos. Se analiza de forma observacional-prospectiva a 46 pacientes con AAA tratados mediante abordaje endovascular en el año 2004, de los cuales 27 reciben un montaje aortomonoilíaco y 19 bifurcado. Resultados. Se obtiene una dosis de radiación total de 48,62 mSv el primer año; esta dosis no difiere entre los pacientes a los que se les coloca una endoprótesis aortomonoilíaca o una bifurcada. Conclusiones. La dosis obtenida no produce un efecto nocivo apreciable el primer año en lo que respecta a efectos deterministas de la dosis empleada. La mayor parte de la dosis recibida se debe a los estudios con tomografía axial computarizada. La resonancia magnética puede jugar un papel muy importante para la reducción de la dosis necesaria en el futuro


Introduction. It is becoming increasingly more frequent to treat abdominal aortic aneurysms (AAA) using endovascular techniques and as a result the doses of radiation patients receive, both in the diagnosis and intervention as well as in the ensuing follow-up, are higher than in conventional surgical treatment. It is essential to define the reference radiation dosage levels that are needed to perform the operation. Aim. To quantify the total dose received by patients submitted to this kind of treatment. Patients and methods. An observational-prospective study was conducted to analyse 46 patients with AAA who were treated using an endovascular approach in the year 2004; aortomonoiliac devices were utilised in 27 cases and 19 received bifurcated stents. Results. A total radiation dose of 48.62 mSv was obtained in the first year; patients received the same dose regardless of whether an aortomonoiliac or a bifurcated stent had been placed. Conclusions. The dose obtained does not give rise to any appreciable adverse effects in the first year as far as dosage-determined effects are concerned. The greater part of the dose received by patients is due to the computerised axial tomography scans that are carried out. Magnetic resonance imaging can play an important role in reducing the doses that are required in the future

ABSTRACT

Introducción. La fístula arteriovenosa (FAV) postraumática que afecta a los vasos poplíteos es una patología de incidencia escasa cuyo tratamiento hasta ahora ha sido quirúrgico; no obstante, también se puede lograr la oclusión de la fístula mediante la implantación de un stent recubierto intraarterial, con reducción extraordinaria tanto del tiempo quirúrgico como de la estancia hospitalaria del paciente. Caso clínico. Varón de 29 años con una FAV en la segunda porción de poplítea derecha, así como falso aneurisma de dos años de evolución provocados por traumatismo por arma blanca. Tras el estudio preoperatorio correspondiente que incluía eco-Doppler y arteriografía, se decidió tratamiento mediante técnica endovascular, que consistió en la implantación de un stent recubierto en la arteria poplítea, con lo que se consiguió al mismo tiempo la oclusión de la fístula y de la comunicación con el falso aneurisma. El tiempo quirúrgico fue de 60 minutos, no se requirió transfusión sanguínea y se dio de alta al paciente en el quinto día de postoperatorio. El eco-Doppler realizado a los 90 días de la intervención muestra la arteria y la vena poplíteas permeables con ausencia de comunicación entre ellas, así como trombosis del falso aneurisma. Conclusión. Las técnicas endovasculares constituyen una alternativa a la cirugía en casos de FAV postraumáticas que afectan a vasos de calibre grande y mediano


Introduction. Post-traumatic arteriovenous fistula (AVF) involving the popliteal vessels is a pathology with a poor incidence being open surgery its treatment of choice. Nowadays however the total occlusion of the fistula can also be achieved by means of the implantation of a covered stent-graft, which implies an important reduction of both surgical time and hospital stay. Case report. A 29-year old man who had a stab wound in the right popliteal fossa two years earlier was admitted with a popliteal AVF involving the middle popliteal segment along with a false aneurysm. After echo-Doppler examination and arteriography the patient was assessed for endovascular treatment that consisted in the implantation of a covered stent-graft thus achieving the occlusion of both the fistula and the false aneurysm. The procedure lasted 60 minutes, blood transfusion was not required and the patient was discharged on the 5th postoperative day. 90 days after operation an echo-Doppler examination was performed that showed patency of both artery and vein, absence of fistula and thrombosis of the false aneurysm. Conclusion. Endovascular techniques are an alternative to open surgery in the treatment of post-traumatic AVF involving large or middle size vessels

ABSTRACT

Introducción. El aumento del número de cateterismos cardíacos para el diagnóstico y el tratamiento de la patología cardíaca se ha acompañado de un incremento en la incidencia de complicaciones vasculares. Las fístulas arteriovenosas tras cateterismo tienen una incidencia escasa (1%). Caso clínico. Varón de 64 años con antecedentes de tabaquismo, dislipemia, hipertensión arterial, broncopatía crónica y cardiopatía isquémica crónica que precisó revascularización quirúrgica hace 18 años y angioplastia con implantación de dos stents hace un año. Fue remitido a nuestro servicio por claudicación intermitente a cortas distancias en el miembro inferior izquierdo de aparición brusca tras realización de cateterismo de control. El estudio arteriográfico demostró la presencia de una oclusión segmentaria de la arteria ilíaca externa izquierda y sendas fístulas arteriovenosas en ambos sectores femorales. El paciente fue intervenido de dichos hallazgos mediante técnica endovascular sin complicaciones perioperatorias. Conclusiones. Se distinguen tres tipos de factores de riesgo en el desarrollo de las fístulas arteriovenosas tras cateterismo: relacionados con el paciente, con el procedimiento y la anticoagulación en relación con éste. La reparación endovascular supone un procedimiento menos agresivo que la cirugía convencional en pacientes seleccionados, que ofrece excelentes resultados a corto y medio plazo


INTRODUCTION. The increasing number of cardiac catheterizations for diagnosis and/or treatment of coronary disease has raised the incidence of vascular complications. This incidence is not high in case of postcatheterization arteriovenous fistulae (1%). CASE REPORT. A 64 year-old man with the following clinical backgrounds: cigarette-smoker, dyslipemia, arterial hypertension, chronic bronchopathy and chronic ischemic cardiopathy, underwent coronary revascularisation 18 years ago; two coronary stent grafts were placed one year ago. He was referred to our department because of sudden onset of short distance intermittent claudication immediately after a diagnostic cardiac catheterization. Arteriography showed a left external iliac artery short occlusion and a bilateral femoral arteriovenous fistula. The patient underwent repair of these lesions by using endovascular techniques without complications. CONCLUSIONS. There are three risk factors for the development of postcatheterization arteriovenous fistulae: those related to the patient, the procedure and the anticoagulation. In selected patients, endovascular repair is less aggressive than open surgery and offers excellent short- and medium-term results

ABSTRACT

Introducción. La morbimortalidad perioperatoria asociada a la cirugía por la rotura de un aneurisma de la aorta abdominal (AAA) se ha venido manteniendo constante en las últimas décadas, alrededor del 50-70%. Con el desarrollo de las técnicas endovasculares disponemos de una alternativa terapéutica a la cirugía abierta que podría tener éxito para disminuir el número de complicaciones a corto plazo. Pacientes y métodos. Presentamos una serie de 16 pacientes intervenidos entre enero del 2001 y agosto del 2005 por rotura de un AAA. Se emplearon endoprótesis aortomonoilíacas y bifurcadas asociadas a diversos procedimientos como embolización del saco aneurismático o implantación de stents entre la hipogástrica y la ilíaca externa. Resultados. La mortalidad perioperatoria fue del 12,5%. Durante los primeros 30 días hubo cinco reintervenciones (31%), dos Friedrich, dos revisiones por sangrado inguinal y un bypass axilobifemoral. En el 37% de los casos se asoció la implantación de stents recubiertos entre la arteria ilíaca externa e hipogástrica. En el 31% de los casos se embolizó el saco aneurismático con Ethiblock®. En un caso hubo que realizar una interposición de un segmento de dacron en la arteria femoral común por desgarro durante la introducción de la endoprótesis. En los primeros 30 días postoperatorios se produjeron diez complicaciones sistémicas graves en cinco pacientes, incluidos un infarto agudo de miocardio, dos íleos prolongados, dos casos de insuficiencia respiratoria aguda, tres casos de insuficiencia renal aguda, y un caso de colitis isquémica que requirió una hemicolectomía. Conclusiones. El uso de técnicas endovasculares en el tratamiento de AAA rotos nos permite reducir la mortalidad a corto plazo a causa de éstos en pacientes seleccionados (AU)


INTRODUCTION. The rate of perioperative morbidity and mortality associated to surgery for rupture of an abdominal aortic aneurysm (AAA) has remained more or less constant over recent decades, with a value of around 50-70%. The development of endovascular techniques has provided us with an alternative to open surgery that could be successful in lowering the number of short-term complications. PATIENTS AND METHODS. We report on a series of 16 patients submitted to surgery between January 2001 and August 2005 to treat an AAA. Aortomonoiliac and bifurcated stents were employed in association with different procedures such aneurysmal sac embolisation or the placement of stents between the hypogastric and external iliac arteries. RESULTS. Perioperative mortality rate was 12.5%. During the first 30 days there were five reinterventions (31%), two Friedrich, two revisions due to inguinal bleeding and one axillobifemoral bypass. In 37% of cases placement of covered stent-grafts between the external iliac and hypogastric arteries was associated to the treatment. In 31% of cases the aneurysmal sac was embolised with Ethiblock®. In one case a segment of dacron had to be inserted in the common femoral artery due to a laceration that occurred during placement of the stent. In the first 30 days of the post-operative period ten severe systemic complications occurred in five patients. These included one acute myocardial infarction, two prolonged ileus, two cases of acute respiratory failure, three cases of acute renal failure, and one case of ischaemic colitis that required a hemicolectomy. CONCLUSIONS. The use of endovascular techniques in the treatment of ruptured AAA makes it possible to reduce the short-term mortality rates from this condition in selected patients (AU)
