[Our experience with sirolimus for the treatment of complicated vascular anomalies]. / Nuestra experiencia con la utilización de sirolimus en el tratamiento de anomalías vasculares complejas.

AIM OF THE STUDY: mTOR inhibitors are being used to treat complex vascular anomalies (VA) without response to conventional treatments. We report our results in pediatric patients treated with sirolimus. METHODS: Retrospective review of patients treated with sirolimus between 2014 and 2017, analyzing vascular anomaly type, treatment response and complications. Treatment protocol included patients with complex vascular anomalies, after signing the informed consent. The initial dose was 0.8 mg/m2/12 h, verifying plasmatic levels. Favorable response was defined both in clinical and radiological terms. MAIN RESULTS: Sirolimus was employed in nine patients, median age 14 months old (1 month-14 years), 66% girls. Five complex micro-cystic lymphatic malformations (LM), one multifocal lynphangioendotheliomatosis with thrombocytopenia, one kaposiform lymphangiomatosis, one lymphatic-venous malformation and one kaposiform hemangioendothelioma (KHE) were treated. Median treatment was 4 months (IQR 2-18 months). Resolution or improvement was objectified in four patients (44%). KHE patient presented complete resolution after two months of treatment. Two patients with micro-cystic LM and the one with lymphatic-venous malformation improved after a median treatment of three months. Two patients presented rebound effect after discontinuing treatment. Three patients had hypertransaminasemia and hypercholesterolemia without requiring medical treatment. CONCLUSION: Sirolimus presented mild effects for treatment of complex VA in our study, but was highly resolutive at KHE.

OBJETIVOS: Los inhibidores mTOR se están utilizando para el tratamiento de anomalías vasculares (AV) complejas sin respuesta a tratamientos convencionales. Presentamos nuestros resultados en pacientes pediátricos tratados con sirolimus. METODOS: Análisis retrospectivo de pacientes tratados con Sirolimus, entre 2014 y 2017, describiendo el tipo de anomalía vascular, respuesta al tratamiento y complicaciones derivadas de su empleo. Se incluyeron pacientes con anomalías vasculares complejas, tras firma del consentimiento informado y con dosis inicial de 0,8 mg/m2/12 horas, monitorizando niveles plasmáticos. Se definió respuesta favorable tanto en términos clínicos como radiológicos. RESULTADOS: Recibieron sirolimus 9 pacientes, mediana de edad de 14 meses (RIQ: 1 mes-14 años). El 66% fueron niñas. Se trataron 5 malformaciones linfáticas (ML) microquísticas complejas (en algunas como coadyuvante a otros tratamientos), 1 linfangioendoteliomatosis multifocal con trombopenia, 1 linfangiomatosis kaposiforme, 1 malformación mixta veno-linfática, 1 hemangioendotelioma kaposiforme (HEK). Mediana de tratamiento: 4 meses (2-18 meses). En 6 pacientes (66%) se objetivó resolución o mejoría de las lesiones. El paciente con HEK mostró resolución completa tras 2 meses de tratamiento. En dos pacientes con ML microquística y en el paciente con malformación mixta, se apreció mejoría clínica y disminución del tamaño de las lesiones tras una mediana de tratamiento de 3 meses. Se apreció efecto rebote en dos ML al suspender el tratamiento. Tres pacientes presentaron hipertransaminasemia e hipercolesterolemia, sin precisar tratamiento médico. CONCLUSIONES: En nuestro estudio, objetivamos que el sirolimus tuvo una eficacia moderada en el tratamiento de AV complejas, pero fue resolutivo en el HEK.

[Laparoscopic repair of inguinal hernia and communicating hydrocele in children. Our experience in the last years]. / Reparación laparoscópica de la hernia inguinal e hidrocele en edad pediátrica. Nuestra experiencia en los últimos años.

INTRODUCTION: Laparoscopic inguinal hernia and hydrocele repair has become an alternative to the more frequently used inguinal approach. We describe our experience with the laparoscopic technique. MATERIAL AND METHODS: Retrospective study of laparoscopic inguinal hernia and hydrocele repair performed during the period between 2003-2016. We included patients < 14 years, with communicating hydrocele and/or indirect inguinal hernia diagnosis (N = 39). We have studied two cohorts; group A patients with indirect inguinal hernia (N = 31) and group B patients with communicating hydrocele (N = 8). We used intraperitoneal laparoscopic approach, performing herniorrhaphy of the internal inguinal orifice without resection of the hernial sac. The main outcome measurements were surgical indication and postoperative complications. RESULTS: The indication for laparoscopic repair was bilateral defects (46.2%), unilateral defects (28.2%), defects associated with umbilical hernia (23.1%) and associated with another pathology (2.6%). In group A the rate of complications that required new admission was 3.2% and the recurrence rate was 9.7%. In group B, was 12.5% ​​and 12.5% respectively. We have not observed a significant relationship with respect to patient age, laterality or suture used and the rate of complications in any of the groups. CONCLUSIONS: Despite the limitations of our study given the small sample size and retrospective nature, the complication rate (15%) is higher than that published in the literature. This makes us take a step back to reassess our indications and technique, and not forget that the laparoscopic approach is not a technique without risks and requires a learning curve.

OBJETIVOS: La reparación laparoscópica de la hernia inguinal e hidroceles en la edad pediátrica, se ha convertido en una alternativa a la herniorrafia inguinal clásica. Describimos nuestra experiencia en las intervenciones realizadas con dicha técnica. MATERIAL Y METODOS: Estudio retrospectivo de las reparaciones laparoscópicas de hernia inguinal e hidrocele realizadas en el periodo 2003-2016. Se han incluido pacientes <14 años, diagnosticados de hidrocele comunicante y/o de hernia inguinal indirecta (N=39), divididos en dos cohortes: grupo A pacientes con hernia inguinal indirecta y grupo B pacientes con hidrocele comunicante. Se ha empleado el abordaje laparoscópico intraperitoneal, y anillorrafia del orificio inguinal interno sin resección del saco herniario. Las variables principales estudiadas han sido la indicación quirúrgica y las complicaciones postquirúrgicas. RESULTADOS: Las indicaciones quirúrgicas han sido los defectos bilaterales (46,2%), defectos unilaterales (28,2%), defectos asociados a hernia umbilical (23,1%) y asociados a otra patología (2,6%). En el grupo A la tasa de complicaciones que precisaron de ingreso fue de 3,2% y la tasa de recurrencias fue de 9,7%; mientras que en el B han sido del 12,5% y del 12,5% respectivamente. No hay una relación significativa respecto a la edad, la lateralidad o la sutura utilizada y la tasa de complicaciones en ninguno de los grupos. CONCLUSIONES: A pesar de las limitaciones del estudio, el porcentaje total de complicaciones (15,3%) es más elevado que el publicado en la literatura. Esto nos hace reflexionar y no olvidar que el abordaje laparoscópico no es una técnica exenta de riesgos y requiere de una curva de aprendizaje.

[Long-term results of hypospadias surgery. Urinary and sexual function, and psychological impact]. / Resultados a largo plazo de la cirugía de hipospadias. Función urinaria, sexual e impacto psicológico.

OBJECTIVES: To determine the current status of the patients operated on for hypospadias in our region, in order to adapt the surgical technique to their real needs. MATERIAL AND METHODS: A descriptive and observational study. Interviews were conducted with hypospadias surgery patients in our hospital between 1976 and 1996, focusing on their urinary and sexual function and psychological impact. We performed a descriptive statistical analysis and comparisons between types of hypospadias (SPSSv19). RESULTS: 566 patients were operated on for hypospadias during the study period, interviewing 100 aged between 18 and 40 years. The 73% were distal and 27% proximal. Of all patients, 30% do not have an orthotopic meatus, 10% have fistula, 18% have some degree of stenosis and 52% have penile curvature. The 13% feel to have had disadvantages in their life. They consider they have a different penis in: size (19%), glans shape (17%), curvature (14%), scars (10%) and lowest hole (7%). Sexual satisfaction was valued at 8.9 on a scale of 1 to 10, with no differences between the types of hypospadias. Proximal hypospadias patients have more ejaculation problems: 42% versus 11% in distal hypospadias. The 68% of the proximal ones would like to improve compared to 20% of the distal in: appearance (17%), size (11%) and way to urinate (11%). CONCLUSIONS: Anatomic abnormalities are maintained but the aspects that values the adult patient differ from those persecuted by practiced surgeries. A significant percentage of patients would try to get another surgery. Keeping the size of the penis and natural appearance of the glans should be a priority in hypospadias surgery.

OBJETIVOS: Conocer el estado actual de los pacientes intervenidos por hipospadias en nuestra región, para adaptar la técnica quirúrgica a sus necesidades reales. MATERIAL Y METODOS: Estudio descriptivo y observacional. Se entrevistó a pacientes intervenidos de hipospadias en nuestro hospital entre 1976 y 1996, incidiendo en su función urinaria, sexual e impacto psicológico. Realizamos análisis estadístico descriptivo y comparaciones entre tipos de hipospadias (SPSSv19). RESULTADOS: 566 pacientes fueron intervenidos de hipospadias en el período estudiado, entrevistándose a 100, con edades entre 18 y 40 años. El 73% fueron distales y 27% proximales. En el 30% el meato no es ortotópico, 10% presenta fístula, 18% presenta algún grado de estenosis y 52% presenta curvatura. El 13% siente haber tenido desventajas en su vida. Consideran su pene diferente en: tamaño (19%), forma glande (17%), curvatura (14%), cicatrices (10%) y orificio más bajo (7%). La satisfacción sexual fue valorada en 8,9 en una escala del 1 al 10, sin diferencias entre los tipos de hipospadias. Los proximales presentan mayores problemas de eyaculación: 42% frente al 11% de los distales. El 68% de los proximales desearían mejorar frente al 20% de los distales, en apariencia (17%), tamaño (11%) y forma de orinar (11%). CONCLUSIONES: Se mantienen alteraciones anatómicas pero los aspectos que más valora el paciente adulto difieren de los perseguidos en las cirugías que se practicaban. Un porcentaje importante de pacientes se reoperaría de nuevo. Mantener el tamaño del pene y aspecto natural del glande debe ser un objetivo prioritario durante la cirugía de hipospadias.

[Prevention of the wound infection: little changes, huge results]. / Resultados de la modificación de la actitud ante la asepsia en cirugía neonatal: pequeños cambios, grandes resultados.

INTRODUCTION: Neonatal surgical wound infection occurs in almost 50% of neonatal procedures. It increases the rates of morbimortality in neonatal units. There is no guidelines about prevention of wound infection in neonatal surgery. We present our results after changing our behaviour in neonatal surgery. MATERIALS AND METHODS: Comparative study between 2 groups. In order to decrease wound infection at the end of the procedure gloves, covertures and surgical instruments were changed and saline and antiseptic solutions were used during laparotomy closing. Group P included procedures with these recommendations and Group NP without them. Age, weight, surgery, infection, length of stay, and mortality were analized between groups through a logistic regression model. RESULTS: Group P included 55 procedures in 32 patients, median weight 1,300 g (1,000-2,100), 19 median days of life (6-40), 5 postoperative wound problems (9%). Group NP included 26 procedures in 14 neonates, median weight 1,700 g (700-2,500), 20 median days of life (3-33), 14 wound problems (53.8%). We decrease the wound problems in our patients in 44.8% (p < 0.0001). Additionally, the protection provided by our recommendations was maintained after adjustment by weight, age and type of pathology (0.07) p= 0.000. CONCLUSIONS: Simple changes in during the procedures in neonatal surgery can reduce the appearance of wound infection and morbidity.

OBJETIVOS: La infección de herida quirúrgica neonatal tiene una incidencia de hasta el 50% y produce un aumento de morbimortalidad. No existen recomendaciones preventivas consensuadas en la literatura. Presentamos los resultados tras la implantación de un protocolo creado en nuestro Servicio para cierre de laparotomía en cirugía neonatal contaminada y sucia. MATERIAL Y METODOS: Estudio ambispectivo de las laparotomías neonatales realizadas durante 32 meses comparando los resultados con un grupo de pacientes intervenidos durante un período previo similar. El protocolo incluye cambio de guantes, de campo y material quirúrgico, lavado por planos con antiséptico y sutura antibacteriana en el cierre. Se analizan edad, peso, tipo de intervención, infección, estancia hospitalaria y mortalidad y se compara con un grupo similar de pacientes intervenidos de forma previa a la creación del protocolo (NP) y se analiza la influencia del protocolo en la aparición de infección mediante regresión logística. RESULTADOS: El grupo P incluye 55 laparotomías en 32 neonatos con mediana de peso 1.300 g (1.000-2.100), mediana de edad 19 días (6-40) con 3 infecciones de herida (2 cultivos positivos) y 2 dehiscencias leves (9%). El grupo NP incluyó 26 intervenciones en 14 neonatos, mediana de peso 1.700 g (700-2.500), mediana de edad 20 días (3-33), 14 infecciones (53,8%), 8 cultivos positivos y 2 muertes. Se redujo un 44,8% la aparición de infección (p < 0,0001) y el efecto protector del protocolo se mantuvo después del ajuste por peso, edad y tipo de patología (0,07) p= 0,000. CONCLUSIONES: La sencilla modificación de la asepsia y técnica de cierre ha contribuido a disminuir considerablemente la tasa de infección y morbimortalidad en nuestros pacientes y consideramos que es necesario hacer conciencia de ello.

[Use of ultrasound for placement of central venous catheters in pediatrics: results of a national survey]. / Uso de la ecografía en la colocación de catéteres venosos centrales en pediatría: resultados de una encuesta nacional.

OBJECTIVES: To study the variability of techniques used for vascular access of central venous devices, totally implanted and external tunneled, as well as polling the use of ultrasound by pediatric surgeons in Spain. MATERIAL AND METHODS: Descriptive study of a survey results, conducted by phone, email and online, about 20 items related to the placement of these devices in children and the use of ultrasound in this procedure. RESULTS: We analyzed 71 surveys from 31 national hospitals. The response rate was 54%. In 66% of the cases the pediatric surgeon is the one who carries out the vascular access. 75% of the respondents place less than 25 catheters/year. Only 28% have attended to an ultrasound-guided vascular puncture course. The vein used more often is the internal jugular (55%), followed by the subclavian (17.4%), with preference for the right side in most of the cases (87%). 64% perform the ultrasound-guided technique, 29% the venous cutdown and 7% the landmark approach. There is no significant association between the technique chosen (landmark vs ultrasound-guided) and the vein used (p= 0,062). The majority of the respondents does not modify the usual approach in case of coagulopathy. We describe the complications associated with the three techniques. CONCLUSIONS: The preferred via for the vascular access by pediatric surgeons is the internal jugular vein, being this access ultrasound-guided in most of the cases. 91.5% consider the use of ultrasound decreases the number of associated complications. Nevertheless, just a minority has attended to a training course.

OBJETIVOS: Estudiar la variabilidad de técnicas en el acceso vascular de catéteres intravenosos centrales totalmente implantados y tunelizados externos, así como indagar sobre la utilización de la ecografía por parte de los cirujanos pediátricos en España. MATERIAL Y METODOS: Estudio descriptivo de los resultados de una encuesta realizada por vía telefónica, correo electrónico y on-line, acerca de 20 ítems relacionados con la colocación de estos dispositivos en niños y el uso de la ecografía. RESULTADOS: Se analizaron 71 encuestas de 31 hospitales españoles. La tasa de respuesta fue del 54%. En el 66% de los casos es el cirujano el que realiza el acceso vascular. El 75% de los encuestados coloca menos de 25 catéteres/año. Solo el 28% realizó algún curso de punción ecoguiada. La vena más utilizada es la yugular interna (55%), seguida de la subclavia (17,4%), prefiriendo la mayoría el lado derecho (87%). Un 64% realiza punción ecoguiada, un 29% venotomía y un 7% punción por referencias anatómicas, sin asociación significativa entre la técnica de punción elegida (referencias anatómicas vs ecoguiada) y la vena utilizada (p= 0,062). La mayoría no modifica la técnica habitual ante la presencia de coagulopatía. Se describen las complicaciones asociadas a las tres técnicas. CONCLUSIONES: La vía preferida por los cirujanos pediátricos encuestados para el acceso vascular es la vena yugular interna, siendo ecoguiado en la mayoría de los casos. Un 91,5% opina que la ecografía disminuye el número de complicaciones asociadas, sin embargo solo una minoría ha realizado algún curso de formación.

[Management protocol in gastroschisis]. / Protocolo de manejo en las gastrosquisis.

AIM: There are two classical managements in gastroschisis: primary or delayed closure. From 2007 on, a multidisciplinary approach protocol based in preterm caesarean delivery at 34-35th gestational age (in order to minimize peel injury) plus primary closure is followed in our institution. Prior to this, term delivery, either by caesarean section or not, was the rule. METHODS: Retrospective study of gastroschisis's patients before (1978-2006) and after (2007-2016) protocol approval. Complex gastroschisis frequency, peel's presence, primary or delayed closure, complications, re-interventions, neonatal intensive care unit (NICU) length of stay, age at onset of enteral nutrition, total parenteral nutrition's length and length of stay were compared. MAIN RESULTS: Study groups: before (12 patients) and after (13 newborns) the protocol implantation (pre/post). Nine complex gastroschisis were observed in the pre-protocol period, compared to one in the post-protocol era (p= 0.001). The re-interventions also decreased: 58.33% in the pre-protocol vs. 15.38% in the post-protocol group (p= 0.025). Complications rate were 66.67% before protocol vs. 23.07% after protocol (p= 0.028). NICU length of stay decreased from 40 ± 32 to 17 ± 12 days (p= 0.025). Parenteral total nutrition length was 61 ± 36 in the pre-protocol vs. 15 ± 6 in the port-protocol eras, respectively (p= 0.043). The age at onset of enteral nutrition was 34 ± 26 vs. 9 ± 5 days (p= 0.004) and hospitalization length was 98 ± 81 days pre vs. 35 ± 15 days post protocol implantation (p= 0.011). CONCLUSIONS: The protocol implantation has allowed primary closure, decreased hospitalization; reduced complications and mortality rate as well.

OBJETIVOS: Clásicamente existen dos manejos de las gastrosquisis: cierre directo o diferido. Nosotros apostamos por el cierre directo aplicando un protocolo de actuación en el que se programa cesárea a las 34-35 semanas de gestación para minimizar el "peel". MATERIAL Y METODO: Estudio retrospectivo de los pacientes con gastrosquisis en los períodos pre (1978-2006) y post (2007-2016) implantación del protocolo, comparando frecuencia de gastrosquisis complejas, la presencia o ausencia de peel, cierre directo o diferido, complicaciones, reintervenciones, días de ingreso en unidad de cuidados intensivos, edad al inicio de nutrición enteral, nutrición parenteral total y días de hospitalización. RESULTADOS: Grupo de estudio: previo (12) y posterior (13) al protocolo (previo/post). La frecuencia de gastrosquisis complejas en el período previo fue de 9 neonatos, en el período post solo 1 (p= 0,001). El número de reintervenciones fue de 58,33% previo vs. 15,38% post (p= 0,025). Las complicaciones postoperatorias fueron 66,67% previo frente a 23,07% post (p= 0,028) y existió una disminución de los días de estancia en la unidad de cuidados intensivos de 40 ± 32 vs. 17 ± 12 (p= 0,025) y de los días de nutrición parenteral (61 ± 36 frente a 15 ± 6; p= 0,043). La edad al inicio de la nutrición enteral fue de 34 ± 26 vs. 9 ± 5 días (p= 0,004) y los días de hospitalización fueron de 98 ± 81 días previo frente a 35 ± 15 días post protocolo (p= 0,011). CONCLUSIONES: La implantación del protocolo ha permitido el cierre directo, la disminución de la estancia hospitalaria, de las complicaciones y de la mortalidad.

[Animated biofeedback for the dysfunctional voiding syndrome]. / Biofeedback animado para el tratamiento de la micción disfuncional.

OBJECTIVES: To analyze clinical and electromyographic treatment outcome of dysfunctional voiding (DV) with animated Biofeedback (Bfb). Clinical or electromyographic variables associated with higher success rate were checked. PATIENTS AND METHODS: Cross-sectional study of patients with DV, that in 2010- 2015 followed animated Bfb program. Efficacy was measured with Uroflowmetry, Electromyography (EMG) and validated clinical questionnaire. Inclusion criteria: no myelodysplasia, no anatomical malformations and a minumin of 3 Bfb sessions. Clinical variables: age, number of sessions, daytime leaks, nocturnal enuresis, constipation, UTI, VUR. Flow measurement variables: morphology of curves, electromyogram, flows, and elevated post void residual (PVR). RESULTS: Of 37 patients who received Bfb, 27 girls who met inclusion criteria were selected. Mean age: 7.8 years (2.5). Twelve (44%) had detrusor overactivity on urodynamics concomitantly. Globally, all clinical and flowmetry parameters improved. Clinically 33.5% had complete resolution of symptoms, 37% improved (> 50% of symptoms according to criteria ICCS) and 29% had no improvement. In EMG, 74% achieved normal perineal relaxation. Constipation at baseline is associated with lower rates of success (cure: 13 vs. 58%, p = 0.019; cure + improvement: 60% vs. 83% p> 0.05). The absence of RPM at the end of the study was associated with clinical improvement (cure: 66.7% vs. 0%, p = 0.012; cure + improvement: 89% vs. 60%, p> 0.05). CONCLUSIONS: Bfb in DV provides cure or improvement and electromyographic resolution are 69 and 74% respectively. The absence of constipation is associated with higher success rates. The High RPM correlates with persistence of clinics.

OBJETTIVOS: Se pretende analizar resultado clínico y electromiográfico del tratamiento de la micción disfuncional (MD) con Biofeedback (Bfb) animado. Además, se estudia si existen variables clínicas o electromiográficas asociadas a mayor tasa de éxito. PACIENTES Y METODOS: Se realizó corte transversal de pacientes con MD, que en 2010- 2015 siguieron programa de Bfb animado. El control post-tratamiento se realizó con Uroflujometría más Electromiografía y cuestionario validado. Se excluyeron los pacientes con mielodisplasia, malformaciones anatómicas, y a los que recibieron menos de 3 sesiones. Las variables clínicas estudiadas fueron: edad, número de sesiones, fugas diurnas, enuresis nocturna, estreñimiento, ITU, RVU. Las flujométricas fueron: morfología de curvas, electromiograma, flujos, y residuo postmiccional (RPM) elevado. RESULTADOS: De 37 pacientes que recibieron Bfb, se seleccionaron 27 niñas que cumplieron criterios de inclusión. Edad media: 7,8 años (DE: 2,5). Doce (44%) presentaron hiperactividad del detrusor asociado a la MD. De manera global, todos los parámetros clínicos y flujométricos mejoraron. Clínicamente 33,5% presentó resolución completa de síntomas y el 37% mejoraron (desaparecieron más del 50% de los síntomas según criterios ICCS). El 29% no presentó mejoría. Electromiográficamente el 74% logró flujometrías normales. El estreñimiento al inicio del estudio se asocia a tasas menores de éxito (curación: 13 vs. 58%, p= 0,019; curación + mejoría: 60% vs. 83% p > 0,05). La ausencia de RPM al final del estudio se relacionó con la mejoría clínica (curación: 66,7% vs. 0%, p= 0,012; curación + mejoría: 89% vs. 60%, p > 0,05). CONCLUSIONES: El Bfb en la micción disfuncional proporciona tasas de curación/mejoría clínica y de resolución electromiográfica del 69 y 74%, respectivamente. La ausencia de estreñimiento se asocia a mayores tasas de éxito. La persistencia de clínica se relaciona con RPM elevado post-tratamiento.

[Testicular and paratesticular tumors in prepubertal children]. / Tumores testiculares y paratesticulares en la etapa prepuberal.

OBJECTIVES: To describe our experience in testicular and paratesticular tumors during the prepubertal stage, focusing especially on its character of benignity/malignancy and surgical treatment used. MATERIAL AND METHODS: Retrospective review of all testicular tumors in children under 12 years diagnosed and treated in our clinical setting from 1998-2015. Data on their presentation, study and management were collected. RESULTS: 17 children with prepubertal testicular tumors were identified. The clinical presentation as palpable testicular mass occurred in 12 cases (70.5%). Levels of tumor markers (alpha-fetoprotein and ßhCG) were only increased alpha-fetoprotein in two cases. In the histopathological study, 64.7% of the tumors were benign (five mature teratomas, four Leydig cells tumors, one immature teratoma and one sexual cords-stromal tumor). Malignant tumors were three rhabdomyosarcoma (17.6%), two yolk-sac tumors (11.8%) and one Burkitt lymphoma (5.9%). The mean age of benign was 5.9 years old and malignant 2.9 years old (p=0.68). From neoplastic lesions nine were non-germline (53%) and eight germline (47%). In the management testis-sparing surgery was performed in six benign tumors, and orchiectomy in five benign tumors and in all malignant tumors except lymphoma which received chemotherapy. CONCLUSIONS: Benign primary testicular and paratesticular tumors are more frequent in prepubertals and testis-sparing surgery is indicated by inguinal approach.

OBJETIVOS: Describir nuestra experiencia en tumores testiculares y paratesticulares en la etapa prepuberal, incidiendo sobre todo en su carácter de benignidad/malignidad y el tratamiento quirúrgico empleado. MATERIAL Y METODOS: Revisión retrospectiva de todos los tumores testiculares en menores de 12 años, diagnosticados y tratados en nuestro ámbito clínico desde 1998 hasta 2015. Se recogieron datos sobre su forma de presentación, estudio y manejo. RESULTADOS: 17 niños con tumores testiculares prepuberales fueron identificados. La presentación clínica como masa palpable testicular se dio en 12 casos (70,5%). De los niveles de marcadores tumorales (alfa-fetoproteína y ßhCG), solo estuvo aumentada la alfa-fetoproteína en dos casos. En el estudio anatomopatológico, el 64,7% de los tumores fueron benignos (cinco teratomas maduros, cuatro tumores de células de Leydig, un teratoma inmaduro y un tumor de los cordones sexuales-estromal). Los tumores malignos fueron tres rabdomiosarcomas (17,6%), dos tumores del saco vitelino (11,8%) y un linfoma de Burkitt (5,9%). La edad media de los benignos fue 5,9 años y de los malignos 2,9 años, (p=0,68). De las lesiones neoplásicas nueve fueron de estirpe no germinal (53%) y ocho germinales (47%). En el manejo quirúrgico se realizó tumorectomía en seis tumores benignos, orquidectomía en cinco tumores benignos y en todos los tumores malignos salvo el linfoma que sólo recibió quimioterapia. CONCLUSIONES: Los tumores testiculares y paratesticulares primarios benignos son más frecuentes en la etapa prepuberal y en su tratamiento se acepta indicar cirugía conservadora por vía inguinal.

[Pediatric Extracorporeal Shock Wave Lithotripsy]. / Litotricia extracorpórea en pacientes pediátricos.

INTRODUCTION: Extracorporeal Shock Wave lithotripsy (ESWL) is the cornerstone of pediatric urolitiasis management. We evaluated its efficacy and complications in a series of children. MATERIAL AND METHODS: Children who were managed with ESWL between 2003 and 2012 were retrospectively reviewed. We studied etiology, clinical presentation, stonefree ratio and relevant complications. SPSS 17.0 software was used. RESULTS: 90 children aged 0 to 10 years (median 2.9 years) were included in the study; that accounted for 122 stones and 162 ESWL sessions. Mean follow up was 20 months. Mean stone diameter was 12.2 mm. (range 4-25). Most prevalent clinical sign was urinary infection (55.6%, 50 patients). 75.4% of the lithiasis were found in renal pelvis or calices. A mean of 1.42 ESWL sessions per stone was performed. Stonefree status was reached in 80.3% (98) of the lithiasis. This rate was higher in patients below 5 years of age (86.1% vs., 69.8%, p=0.03), and worse in staghorn calculi (66% vs. 87.2%) and cystine ones (30% vs. 84.8%, p<0.001). We observed 17 complications (10.4% among 162 sessions), 6 UTIs, 6 episodes of fever and 6 episodes of UTI associated with steinstrasse. Almost all complications were associated with bigger size, staghorn calculi and struvite. DISCUSSION: Best results are found in younger patients and small calculi. ESWL is a safe and efficient procedure in pediatric patients.

INTRODUCCION: La Litotricia Extracorpórea por Ondas de Choque (LEOC) constituye el pilar fundamental de la urolitiasis infantil. En este trabajo pretendemos objetivar la tasa de fragmentación y expulsión de cálculos mediante LEOC. MATERIAL Y METODOS: Revisión retrospectiva de procedimientos de LEOC pediátricos, analizando etiología, clínica, tasa de éxito, factores asociados al mismo y complicaciones. Análisis: SPSS 17.0. RESULTADOS: Se revisaron 90 niños (edad: 8 meses-10 años -mediana 2,9 años) que habían presentado 122 litiasis y precisaron 162 procedimientos de LEOC entre 2003 y 2012. Mediana de seguimiento: 20 meses. Diámetro medio del cálculo: 12,2 mm (rango 4-25 mm). La clínica más habitual fue Infección del Tracto Urinario (ITU) (55,6%, 50 niños). El 3,3% de los cálculos se localizaron en vejiga, el 21,3% en uréteres y el 75,4% en riñón. Se realizó una media de 1,41 LEOC por episodio litiásico. Se consiguió fragmentación y expulsión en el 80,3% (98) de los cálculos. Esta tasa fue mayor en niños menores de 5 años (86,1% vs. 69,8%, p=0,03) y en cálculos asociados a prematuridad y estancia prolongada en UCI (100% vs. 78,4%, p=0,19); y peor en cálculos coraliformes (66% vs. 87,2%, p=0,021), y en los de cistina (30% vs. 84,8%, p<0,001). Entre los 162 procedimientos, hubo 17 complicaciones (10,4%): (6 ITUs ­3,7%­, y 5 ITUs asociadas a calle litiásica ­3%­), todas relacionadas con cálculos grandes, coraliformes y/o de estruvita. CONCLUSION: Los mejores resultados en LEOC se objetivan en los pacientes de menor edad. La LEOC pediátrica es eficaz y segura.

[Ultrasound markers in the follow up of pyeloplasty]. / Evolución de los parámetros ecográficos tras pieloplastia en la población infantil.

INTRODUCTION: There are few studies on the long term follow up of pyeloplasty. Is there a residual pelvis dilatation in all successful procedures? How is the long term evolution of the ecographic parameters and measures postoperatively (PO)? PATIENTS AND METHODS: We reviewed all successful Anderson-Hynes pyeloplasties performed on obstructed renal pelvis with an anterio-posterior diameter >15 mm during 2001-2010. Ultrasound controls were made at 3 and 6 months postoperatively and then yearly afterwards. We aimed to describe time course of hydronephrotic changes following unilateral pyeloplasties, using three parameters: pelvic anterior-posterior diameter (APD), pelvis/córtex ratio (P/C R) and the percentage of improvement in APD (PI-APD). RESULTS: 41 patientswereincluded. Age at intervention ranged from 2 months to 10.3 years (mean 13 months, 83% were operated in the first year of life). Median of follow up was 4 years (range 1-12 years). Mean APD preoperatively was 25 mm (range 16-54). At the third month PO, PI-APD was 28%. At the sixth month control, it was 51%, and remained stable during the next consecutive yearly controls, without statistically significant variations (50%, 57%, 60%, 51%, 39%, 46%, 38%, 42%). P/C R diminished significantly already in the third month control (4.6 vs. 1.8, p=0.03). We observed complete disappearance of hidronephrosis in 8 patients (19.5%). DISCUSSION: Although early postoperative ultrasound changes occur, the ultrasound parameters remain often stable during long term follow up. We documented the complete normalization of renal pelvis (no hydronephrosis) in one of every five patients.

INTRODUCCION: Hay pocos estudios sobre la evolución postquirúrgica a largo plazo de la estenosis de la unión pieloureteral (EUPU). ¿Existe una dilatación residual en todos los pacientes que presentan resultados satisfactorios tras la cirugía? ¿Cuál es la evolución en los parámetros ecográficos? PACIENTES Y METODOS: Revisión retrospectiva de pacientes con EUPU intrínseca, con diámetro anteroposterior (AP) de la pelvis >15 mm (e hidronefrosis grado III o superior), y seguidos tras pieloplastia de Anderson-Hynes en el periodo 2001-2010 (10 años), no reintervenidos, asintomáticos y con función renal normal. Los controles ecográficos se hicieron a los 3 y 6 meses postoperatorio (PO) y posteriormente anuales. Se midieron tres parámetros: diámetro AP, ratio pelvis/córtex (R P/C) y porcentaje de mejoría (PM). RESULTADOS: Se seleccionaron 41 pacientes, intervenidos entre 2 meses y 10,3 años (media 13 meses, 83% en primer año de vida), mediana de seguimiento: 4 años (rango: 1-12). El diámetro AP de la pelvis renal medio pre-quirúrgico fue de 25 mm (rango 16-54). A los 3 meses la disminución media del diámetro AP (o PM) fue del 28% (respecto a diámetro prequirúrgico). A los 6 meses PO, fue del 51%, permaneciendo estable durante los siguientes años: 50%, 57%, 60%, 51%, 39%, 46%, 38%, 42% (controles anuales durante los primeros 8 años). La relación pelvis/córtex disminuyó de manera significativa ya en las ecografías al tercer mes (4,6 vs. 1,8; p= 0,03). En 8 pacientes (19,5%) se pudo objetivar ausencia de dilatación piélica en la evolución. CONCLUSIONES: Aunque los cambios ecográficos tras la pieloplastia se pudieron objetivar desde los controles precoces, permanecieron a menudo sin cambios durante los controles posteriores. Sin embargo, en uno de cada cinco pacientes se objetivó la desaparición de la dilatación piélica.

[Neonatal use of propranolol for segmental facial hemangiomas]. / Uso neonatal del propranolol en hemangiomas segmentarios faciales.

INTRODUCTION: Segmental cervico facial hemangiomas are defined as those longer than 5 cm, affecting a specific facial area. These lesions can be eventually associated with the PHACE syndrome. Our aim is to propose neonatal treatment with propranolol, showing its efficacy/safety, given the scarce evidence on its neonatal use. CLINICAL OBSERVATION: After written informed consent, four patients with segmental facial hemangioma were treated with propranolol in the neonatal period. Adverse effects were registered during initial admission. Three of the four patients had PHACE syndrome. Propranolol was effective in 100% of patients, showing hemangioma´s involution without any adverse effect. COMMENTS: In our series, propranolol was effective and showed no side effects in the neonatal period. If propranolol benefits are greater than its risks, administration of the lowest effective dose is recommended, under hospital surveillance, starting shortly after diagnosis, in order to achieve improved efficacy.

INTRODUCCION: Los hemangiomas cérvico-faciales son considerados segmentarios cuando afectan a un área específica de la cara y miden más de 5 cm y, en ocasiones, forman parte del síndrome de PHACE. Nuestro objetivo es proponer el tratamiento de dichos hemangiomas con propranolol en etapa neonatal, mostrando su eficacia/seguridad dado que existe poca evidencia al respecto. OBSERVACION CLINICA: Revisamos 4 pacientes diagnosticados de hemangioma segmentario facial. Los neonatos fueron tratados de forma hospitalaria inicial con propranolol, tras firma de consentimiento informado, y fueron ingresados para control de aparición de complicaciones. Tres de los cuatro casos clínicos fueron diagnosticados de síndrome de PHACE. El propranolol fue efectivo en el 100% de los pacientes, demostrando involución de los hemangiomas. COMENTARIOS: En nuestra serie el propranolol fue eficaz sin evidenciar complicaciones en el período neonatal. Si los beneficios del propranolol sobrepasan los riesgos, se recomienda administrar la menor dosis eficaz, de forma hospitalaria y precoz para obtener mejores resultados.

[Neonatal surgical site infection: multicentric survey on prophylactic measures]. / Infección de herida quirúrgica neonatal: encuesta multicéntrica sobre medidas profilácticas.

OBJECTIVES: Surgical site infection (SSI) has a considerable impact on neonatal morbidity. There are known risk factors such type of surgery (clean/contaminated), prematurity, surgical length, hypoalbuminemia, previous infection, prolonged mechanical ventilation, and so on. Many perioperative factors have not been studied, opposite to adults. We have developed a survey on intraoperative attitudes and measures, as surgical wound management in Neonates among pediatric surgeons, to seek for a wider consense. METHODS: Multi-response survey with 22 items, based on the Surgical Infection Society NIH 2008 clinical guideline. Each item poses a question on perioperative attitudes, surgical aspects and wound management. Each question is subdivided in two categories, depending on urgency and type of surgery (clean/contaminated). RESULTS: 159 surveys were sent. Among those, we received back 51 (32%). 69% of the interviewed surgeons use clorhexidin to prepare surgical field, 25% use Iodine solutions. 69% never use diathermy to incise skin. There was no agreement on the use of sterile plastic adhesive drapes, intra-cavity lavage, changing surgical gloves/material, or wound irrigation during closure. 82% never use cyanocrilate dressing. Intracuticular skin suture and simple stitches were used indistinctly. Wound management and dressings were not uniform and depended on each pediatric unit. CONCLUSIONS: The survey reflects the lack of consensus regarding prophylactic measures and wound management among pediatric surgeons who care after surgical neonates.

OBJETIVOS: La infección de herida quirúrgica (IHQ) es una causa frecuente de morbimortalidad en Neonatología. Existen factores de riesgo conocidos: tipo de cirugía (sucia/contaminada/limpia), prematuridad, duración de intervención, hipoalbuminemia, infección previa, ventilación mecánica prolongada y contaminación de vía central. Otros factores perioperatorios no han sido estudiados en neonatos, sí en adultos. Desarrollamos una encuesta sobre las actitudes y las medidas, intraoperatorias y de manejo de herida. Pretendemos dilucidar si existe consenso sobre la profilaxis de IHQ neonatal. METODOS: Encuesta con 22 ítems, basada en la guía de prevención de la IHQ en adultos (Surgical Infection Society, 2008). Cada ítem cuestiona temas sobre hábitos perioperatorios, intra y postoperatorios, relacionados con el manejo de la herida quirúrgica en el neonato, y consta de dos preguntas, según sea cirugía sucia/urgente o limpia/contaminada. Las opciones de respuesta son 4: siempre, con frecuencia, raramente y nunca. Enviamos la encuesta a cirujanos pediátricos españoles mediante correo electrónico en el primer trimestre del 2012. RESULTADOS: Se enviaron 159 encuestas. 51 (32%) respondieron. 69% emplean clorhexidina para preparar campo, 25% usan povidona iodada. Solo el 51% refirió dejar actuar siempre un minuto el antiséptico. 69% nunca usan bisturí eléctrico en piel para ampliar herida. No hubo respuestas unánimes en cuanto al uso de paños adhesivos protectores del campo, la irrigación de planos con suero o antisépticos durante el cierre, el empleo de drenajes, cambio de guantes y/o material al iniciar el cierre (cirugía sucia). El 72% y el 82% nunca emplean cianocrilato como cierre o apósito en neonatos, respectivamente. En cirugía sucia, 43% suturan piel con intradérmica y 49% con puntos sueltos. CONCLUSIONES: La distribución de respuestas refleja la falta de consenso sobre los aspectos de la técnica quirúrgica y el manejo perioperatorio que podrían estar relacionados con la profilaxis de IHQ neonatal.

[Study of bacteriology and resistances in pediatric appendicitis]. / Estudio de la flora patógena y resistencias en apendicitis pediátricas.

UNLABELLED: There is controversy about the convenience of performing a bacteriological peritoneal culture in pediatric appendicitis. We performed a sero-epidemiological survey of the bacteria found in peritoneal swabs from pediatric appendicitis operated in our hospital. METHODS: Ambispective study. Retrospective revision of the bacteriological results from peritoneal swabs performed in pediatric appendicitis from january 2009 to december 2010 (2 years) and prospective study of peritoneal swabs collected between january 2011 and december 2011 (one year). RESULTS: We found 728 pediatric patients (mean age 7.1, range: 2-11 years). Among these, 108 were < 5 years. Cultures were performed in 328 (45.1%). A positive result was found in 155 swabs, (47.3%). Positive cultures were more frequent in patients < 5 years (69.2% vs 40.4%, p < 0.001). The most frequent pathogens were E. coli: 122 specimens, Streptococcus spp (50 swabs), P. aeruginosa: (45) and B.fragilis: (35) Younger age was strongly associated with P. aeruginosa: (30.8% vs 8.4%, p < 0.001. OR: 4.8. IC 95%: 2.3-9.8). So was the detection of E. coli (50% vs 33.2% p = 0.01). 21.3% (26 swabs) of E. coli were resistant to amoxicillin-clavulanic acid. There were 15 (12.3%) multiresistant (ESBL) E. coli. Among the Streptococcus, 32% (16 out of 50) were resistant to clindamicin, and so were 28.6% of the B. fragilis (10 out of 35). DISCUSSION: . The most frequent pathogens were E. coli, Streptococcus spp and P. aeruginosa. P. aeruginosa is five times more frequent in patients < 5 years. Resistance of E. coli to amoxiclavulanate was high: 21.3% of the specimens. We found that 12.3% of the E. coli produced ESBL.

[Quality of life and long term results in Hirschsprung's disease]. / Calidad de vida y resultados a largo plazo en pacientes con enfermedad de Hirschsprung.

INTRODUCTION: The most frequent long term side effects of Hirschsprung's disease (HD) surgery are obstructive problems and fecal incontinence. In this study, we analyse long term functional results of the two most used surgical techniques (Duhamel-D- and De la Torre-dlT-) from the patient's point of view, through quality of life and functionality questionnaires. METHODS: We selected short segment HD patients ≥ 4 years) that were operated in our unit from 1996 until 2011. We employed two validated questionnaires: Bowel Function Score (BFS) and Gastrointestinal Quality of Life Index (GIQLI). Both questionnaires were also tested in two control age matched groups, each for every arm (controlD or control dlT). RESULTS: Among 28 preselected patients, 22 (78.6%) answered both questionnaires. Group D (10 patients) showed more constipation: 60% vs. 16.7% ( p = 0.01). Patients in group dlT (12 patients) showed more leaks: 58.3 vs. 10% (p = 0.03). Results of both questionnaires were higher (better) in Group D: 16 vs. 12.8 points (BFS, p = 0.007) and 74.1 vs. 69.8 (GIQLI, p = 0.17). The control group showed an overall better scores than HD patients: 17.2 vs. 14.3 (BFS p = 0.001) and 75.9 vs. 71.8 (GIQLI, p = 0.04). Separately, both groups of patients showed worse scores when compared with each control group. DISCUSSION: Our results are similar to other studies, where global scores of functional results and quality of life are worse in operated HD patients than in age matched controls. Fecal incontinence has more impact on social scores than constipation. Due to the fact that our dlT patients have more frequently fecal leaks, their scores are worse than in the D group. Nevertheless, patients in dlT group are younger and may improve their results as they get older, as it is often the case in operated HD patients.

[Preliminary results of a multidisciplinary approach to gastroschisis]. / Resultados iniciales de un protocolo de manejo terapéutico de la gastrosquisis.

INTRODUCTION: In gastroschisis, premature birth may avoid the development of intestinal peel and favour the primary closure. We present the preliminary results obtained after following a multidisciplinary approach to gastroschisis. After prenatal ultrasound diagnosis, preterm caesarean delivery at 34-35 weeks of gestation is programmed. METHODS: Prospective design of a study, where we included all prenatal diagnosed gastrosquisis neonates, from July 2007 to January 2012. RESULTS: We followed 9 infants (3 male). Average weight at birth: 1,927 gr. (+/- 370). Primary closure was successfully accomplished in the first 3 hours of life all cases. We found two cases of slight peel. We found no associated intestinal malformations, except for one small bowel stenosis. No significant neonatal distress respiratory syndrome developed. Mean parenteral nutrition time was 13.9 days (+/- 3.8). 4 neonates developed central line associated infection. No surgical site infection developed. Enteral nutrition was started at day 8th (+/- 2.8). Enteral requirements were fulfilled at day 15th (+/- 3.6). Mean hospital stay was 31 days (+/- 10). Mean follow-up was 30 months. 4 cases developed a small (< 5 mm) umbilical hernia CONCLUSION: Programming premature cesarean section delivery at 34 weeks of gestation was beneficial to the neonates with gastroschisis, yet it avoided peel development, and rendered primary closure without serious difficulties possible. This diminishes hypoperistalsis time and allows rapid instauration of enteral feeding, so hospital stays may be shorter.

[Uroflowmetry values among asymptomatic children who underwent tubularized incised plate urethroplasty]. / Flujometría en varones asintomáticos intervenidos mediante la técnica de Snodgrass.

PURPOSE: Tubularized incised plate uretroplasty (TIPU) technique for hypospadias repair or Snodgrass procedure has become increasingly popular since its description in 1994. The elasticity of the neouretra is reduced and several studies have pointed out that flow parameters of the patients operated on this procedure show some grade of asymptomatic functional obstruction, although there are reports on the improvement of these parameters on the mid term. We evaluated the functional outcome in the form of urinary flow in asymptomatic children following uncomplicated TIPU. PATIENTS AND METHODS: We reviewed the urine flow rate of asymptomatic toilet trained children who underwent TIPU at our institution between 2005 and 2012. Uroflowmetries were performed in a serial fashion, during the follow up visits at the first months after the repair and yearly afterwards. Unfavourable values were plateau or interrupted curves and peak flow below the 5th percentile of a validated Nomogram for children (Gutiérrez-Segura). Statistical work up: SPSS 15.0. RESULTS: 85 patients were eligible. The mean age at surgery was 2.7 years. Median follow up was 29 months (6-82 months). Hypospadias was distal penile in 76 (89.5%) and mid penile in 9 (10.6%). We obtained 131 uroflowmetries (1.54 per patient) at a mean age of 5.1 years (2.5-8). 66.7% of the peak flow values and 55% of the average flow values were below the 5th percentile of the Nomogram. Flow curve was normal (bell- shaped) in 35 charts (26.5%), irregular in 38 (28.8%) and plateau in 56 (42.4%). Peak flow values improved in the second year after surgery (compared to the first year values): 7 ml/sgvs 8.09 ml/sg (p=0.07). The difference was significative in low volumes (<100 ml) (6.3 vs 7.8 ml/sg, p=0.04). Bell-shaped curve rate also grew: 21% (6/29) vs 28% (29/74), p> 0.05. We constructed a specific Nomogram for this population. CONCLUSIONS: Our data confirm that many asymptomatic patients who undergo TIPU repair present altered flow patterns. Spontaneous partial improvement is the norm after the first year of surgery.

[Functional results of Hirschsprung's disease patients after Duhamel and De la Torre procedures]. / Resultados funcionales en pacientes con enfermedad de Hirschsprung intervenidos mediante las técnicas de Duhamel y De la Torre.

INTRODUCTION: Long term results of different surgical techniques in Hirschsprung's Disease (HD) are contradictory. There are still no long term large or multicentric reports about functional results of De la Torre technique. We have studied the mid term functional results of the patients operated on Duhamel (D) and De la Torre (dlT) pull-through procedures. PATIENTS AND METHODS: We collected data from medical records and telephone interviews of the HD patients operated in our unit in the last 16 years. RESULTS: 38 patients were found. Ages ranged from 1.5 to 21 years. Mean age was 7.7 years. Median follow up was 5.9 years. 33 (86.8%) had rectosigmoid disease and 5 (13.2%) had long segment disease. D procedure was performed in 17 (44.7%), Soave in 1 (2.6%), Duhamel-Lester-Martin in 4 (10.5%) and dlT pull-through in 16(42%). In the last visit record, 12 (31.6%), had constipation, and fecal leaks were noted in 11 (33.3%) of the 33 patients > or = 4 years old.. 10 patients (29.4% of the > or = 4 years old group) referred encopresis along the follow-up. Patients from the D group referred higher rates of constipation than those in the dlT group (53.3% vs 20% p=0.048). dlT patients referred more frequency of leaks (46,1% vs 13,3%, p=0,05) Children with very short resections (< or = 10 cm) were more prone to constipation than children with longer resections (66,6% vs 17.4% p=0.007), and less prone to present leaks (12.5% vs 47.3% p=0.08). Encopresis was similar in all groups. DISCUSSION: Both techniques show similar functional results in the mid term, although children in the D group were more prone to constipation and those in the dlT group presented more fecal leaks. All patients with EH need long follow-ups.

[Birth defects in a cohort of uninfected children born to HIV-infected women]. / Malformaciones congénitas en una cohorte de niños no infectados, hijos de madres infectadas por el virus de la inmunodeficiencia humana.

INTRODUCTION: Mother-to-Child HIV transmission is now just 1% in western countries, due to prevention measures. Antiretroviral Treatment (ART) drugs do have adverse effects, anaemia and myelosupression caused by cidovudina being the most commonly observed effects. In the present study, we have analysed the proportion and characteristics of congenital malformations (CM) or birth defects (BD) in a cohort of uninfected children born to HIV-infected women. METHODS: A total of 623 uninfected children belonging to the FIPSE cohort were followed up according to standardised protocols. This cohort includes 8 public hospitals from Madrid and follows up HIV-infected pregnant women and their children. Children were classified according to prematurity, ethnic origin, birth weight, withdrawal syndrome, in-utero treatment. Birth defects were described and defined according to the EUROCAT, the European registry for BD. Mild errors of morphogenesis were excluded from the analysis. Categorical variables were compared with the X(2) or the Fisher test. RESULTS: A total of 78% (486) of the mothers were of Caucasian origin; 18.8% (117) used some illicit drug (heroine, cocaine or methadone) during gestation; 51 mothers (8.1%) received no ART, 10 (1.6%) received monotherapy and 469 (75.3%) received HAART. BD were seen in 52 children, with the most frequent being genitourinary and cardiological. Anaemia in the first trimester was an associated risk for BD (17.9% vs. 8.1%, P = 0,04). Similarly, mothers who used any illicit drug (plus methadone), had a slightly higher risk for BD in their offspring (13.8% vs. 7.6%, P = 0,04) There was no increased risk for BD significantly associated with any of the in-utero used antiretrovirals, although Nevirapine use in-utero showed a protective effect. Children born to mothers who received ART in the first trimester had the same rate of BD (7.4%) as those whose mothers started ART in the second trimester (8.8%), P = 0,67. CONCLUSIONS: The proportion of BD that we have observed seems higher than those shown in other European teratogenicity studies and also higher than those shown in cohorts with HIV and antiretroviral exposed infants. This may be due to the fact that our series show the results of an active surveillance system (that includes ultrasound), where BD classically appear in a higher proportion. Immunovirological characteristics of the mother did not influence the proportion of BD, but anaemia in the fist trimester and the use of illicit drugs (or methadone) did. No specific antiretroviral drug was associated with an increase in BD, although Nevirapine showed a possible protective effect in the statistical analysis. Mothers who started antiretrovirals in the first trimester do not have more BD in their offspring than mothers who started on antiretrovirals later on.

[Growth of uninfected infants exposed to antiretrovirals born to HIV-infected woman]. / Exposición a antirretrovirales y crecimiento en una cohorte de niños no infectados, hijos de madre con VIH positivo.

INTRODUCTION: Recent reports show that Antiretroviral Treatment (ART) during pregnancy does not affect somatic growth of children born to HIV-infected mothers, are reassuring. The aim of this study is to perform an anthropometric analysis of the uninfected children followed in the Spanish FIPSE cohort during their first 18 months of life, and to describe the possible risk factors during pregnancy that may influence low birth weight. METHODS: The FIPSE cohort includes 8 public hospitals in Madrid, and prospectively follows children born to HIV-infected women at these hospitals. We collected data on 601 uninfected children, following standardised protocols, during their first 2 years of life. A P value<0.05 was considered statistically significant. Data from the Pablo Orbegozo Foundation were used to compare the means of our population with the standard weight, longitude an occipitofrontal circumference (OFC) of the Spanish population during the first 18 months of life. RESULTS: The mean weight was 2766g (+/-590), and 2967g (+/-427) when premature neonates were excluded. The proportion of Intrauterine Growth Restriction among non- premature neonates was 19.8% (95% CI: 16.3-23.8). Children born to mothers that used illicit drugs weighed less: 2752g (+/-325) vs. 3002g (+/ 435), P<0.001, as did children born to mothers who smoked during pregnancy: 2842g (+/-363) vs. 3018g (+/-444), P>0.001. Maternal anaemia did not influence the low birth weight of the children when premature neonates were excluded. We found no statistically significant differences depending on the ART received during pregnancy. Children born to mothers who had CD4 > 500 cell /mm were heavier (2834g +/-503) than those whose mothers had CD4 of less than 200 cell/mm (2565g +/-702), P=0.008. These differences disappeared when premature neonates were excluded. Children born to mothers with undetectable viral load were heavier (2866g +/-532 vs. 2704g +/-588, P=0.005), but these differences also disappeared when the prematures were excluded from the analysis. Mean weight, length, and OFC of our population at birth (excluding premature neonates) were lower than the Spanish standards. (z for weight=-0.83; z for length =-1.02; z for OFC=-1.00), but these differences are not statistically significant and disappear at 18 months of age (z for weight=-0.08; z for height=-0.32; z for OFC=-0.31). The type of ART did not have any significant influence. DISCUSSION: There is a very significant difference between the weight of the children born to mothers addicted to illicit drugs and the rest of the children. Similarly, the weight of the children born to smoking mothers is significantly lower. There was no association between maternal anaemia and the type of ART. The children of our population have lower weights, length and OFC at birth, but this may due to the high number of scheduled caesarean births, practised at 38 weeks of pregnancy (54.5%). Our children catch-up with anthropometric measurements during the first and second year of life, and these are similar to Spanish standards at 18 months old.

[Transanal irrigations in patients with constipation and fecal incontinence: results, indications and follow up in our center]. / Irrigación transanal en pacientes con estreñimiento e incontinencia orgánica refractaria. Resultados, indicaciones y seguimiento en nuestro centro.

AIM OF THE STUDY: To present our results with transanal irrigation (TAI) for management of fecal incontinence and fecal constipation without response to other treatments. METHODS: Retrospective study of patients with fecal constipation and/or fecal incontinence treated with TAI between 2013 and 2017. A Rintala questionnaire(1) was carried out comparing pre and post-treatment results. This study was approved by the ethical committee. MAIN RESULTS: Twenty-five patients were included with a median age of 13 years old (range 6-44 years). Nineteen patients had spinal pathology (76%), four colorectal surgery (16%) and two functional constipation (8%). They presented fecal incontinence in 20% of cases, 12% of fecal constipation and 68% both conditions. After a mean follow-up of 1.5 years (1 month-4 years), 52% of the patients abandoned the treatment. The mean Rintala score was 6.8±4 before treatment, and after, resulted to 11.42±2.75 (p=0.001). The main complications throughout the treatment were pain (68%) and balloon leaks (28%). The patients declared as cause of treatment cessation: reduced mobility (15%), fear or misinformation (32%) and pain (76%). All patients with reduced mobility (n=3) left treatment, versus 45% (n=12) of the patients that had full mobility (p=0.17, OR 8.3 [IC95% 0.3-38]). Complementary treatments such as laxatives, enemas or digital extraction were abandoned in 55% of the patients. CONCLUSIONS: Using TAI seems to improve quality of life in patients with fecal constipation and fecal incontinence refractory compared to other treatments. Our abandonment rate was higher than expected, so we believe it is necessary to create a support group to improve follow-ups.

OBJETIVOS: Presentar nuestros resultados con el uso del irrigador transanal (IT) en el manejo intestinal de pacientes con incontinencia fecal o estreñimiento sin respuesta a otros tratamientos. METODOS: Estudio retrospectivo de pacientes con estreñimiento y/o incontinencia fecal refractaria tratados con IT (2013-2017) con el sistema Peristeen® (Coloplast). Se realizó cuestionario Rintala(1), comparando resultados pre y postratamiento. La realización del estudio fue aprobada por el comité de investigación clínica. RESULTADOS: Fueron incluidos en el estudio veinticinco pacientes, mediana de edad 13 años (6-44 años), cuatro no localizables. Diecinueve presentaban patología medular (76%), cuatro cirugías colorrectales (16%) y dos estreñimiento funcional (8%). El 20% aquejaba incontinencia, 12% estreñimiento y 68% ambas condiciones. Tras una mediana de seguimiento de 1,5 años (1 mes-4 años), el 52% abandonó el tratamiento. La puntuación media pretratamiento fue 6,8±4, frente a 11,42±2,75 tras su empleo (p=0,001), disminuyendo el número de escapes con repercusión positiva en actividades diarias. Las complicaciones principales fueron dolor (68%) y expulsión del balón (28%). Refirieron como causa de abandono: dificultad de uso por movilidad reducida (15%), miedo o desinformación (32%) y dolor (76%). El 100% de pacientes con movilidad reducida (n=3) abandonó el tratamiento, frente al 45% (n=12) en el resto (p=0,17, OR 8.3 [IC95% 0,3-38]). El 55% de los pacientes dejaron de utilizar laxantes, enemas o extracción digital. CONCLUSIONES: El uso de IT parece mejorar la calidad de vida en pacientes con estreñimiento e incontinencia de causa orgánica refractaria. La tasa de abandono fue mayor de la esperada, por lo que creemos necesaria la creación de un grupo de apoyo que mejore el seguimiento.
