Outcomes of pediatric living donor kidney transplantation: A single-center experience.

Renal transplantation is the treatment of choice for children with ESRD offering advantages of improved survival, growth potential, cognitive development, and quality of life. The aim of our study was to compare the outcomes of LDKT vs DDKT performed in children at a single center. Retrospective chart review of pediatric patients who underwent kidney transplantation from 2005 to 2014 was performed. Ninety-one renal transplants were accomplished, and 31 cases (38.27%) were LDKT, and in 96.7% of the cases, the graft was obtained through laparoscopy. Thirty-four receptors weighted <25 kg. LDKT group had statistically significant lower cold ischemia times than DDKT one. Complication rate was 9.67% for LDKT and 18.33% for DDKT. eGFR was better in LDKT. Patient survival rate was 100% for LDKT and 98.3% for DDKT, and graft survival rate was 96.7% for LDKT and 88.33%-80% for DDKT at a year and 5 years. Our program of pediatric kidney transplantation has achieved optimal patient and graft survival rates with low rate of complications. Living donor pediatric kidney transplants have higher patient and better graft survival rates than deceased donor kidney transplants.

Analysis of the therapeutic evolution in the management of airway infantile hemangioma.

AIM: To analyze the evolution in the management of airway infantile hemangioma (AIH) and to report the results from 3 pediatric tertiary care institutions. METHODS: A retrospective study of patients with diagnosis of AIH and treated in 3 pediatric tertiary care institutions from 1996 to 2014 was performed. RESULTS: Twenty-three patients with diagnosis of AIH were identified. Mean age at diagnosis was 6 mo (range, 1-27). Single therapy was indicated in 16 patients and 7 patients received combined therapy. Two therapeutic groups were identified: Group A included 14 patients who were treated with steroids, interferon, laser therapy and/or surgery; group B included 9 patients treated with oral propranolol. In group A, oral corticosteroids were used in 9 patients with a good response in 3 cases (no requiring other therapeutic option), the other patients required additional treatment options. Cushing syndrome was observed in 3 patients. One patient died of a fulminant sepsis. Open surgical excision and endoscopic therapy were performed in 11 patients (in 5 of them as a single treatment) with a response rate of 54.5%. Stridor persisted in 2 cases, and one patient died during the clinical course of bronchial aspiration. In group B, oral propranolol was used in 9 patients (in 8 of them as a single treatment) with a response rate of 100%, with an mean treatment duration of 7 mo (range, 5-10); complications were not observed. CONCLUSION: Our experience and the medical literature support the use of propranolol as a first line of treatment in AIH.

[The efficacy of endoscopic treatment for secondary vesicoureteral reflux. Analysis of a series of 142 cases]. / Eficacia del tratamiento endoscópico del reflujo vesicoureteral secundario. Analisis de una serie de 142 casos.

OBJECTIVES: To evaluate the rate of secondary or complicated vesicoureteral reflux (VUR) among the total number of VUR cases treated in our institution. To determine the efficacy of the endoscopic treatment in secondary or complicated VUR depending on etiology and grade. METHOD: We review our experience with endoscopic treatment for VUR from 1992 to 2006. We have used three different materials: polytetrafluoroethylen (Teflon), polydimethyls iloxane (Macroplastique) and dextranomer/hyaluronic acid copolymer (Deflux). 479 ureters with VUR were treated in 402 patients; 124 patients and 142 ureters of them were secondary or complicated VUR cases. All patients were followed up with urinary tract ultrasound and radiological or isotopic voiding cystogram. Success is defined as VUR disappearance or improvement to grade I VUR without urinary infection after removing antibiotic prophylaxis. RESULTS: The success rate has been 71.13% after the first injection, 85.92% after the second injection and 90.14% after the third injection. Mean subureteral dose has been 0.65 ml. The complications rate has been 0%. CONCLUSIONS: The endoscopic treatment in secondary or complicated VUR is a minimally invasive procedure. It seems to be more difficult than in primary VUR cases, but its low morbidity and efficacy indicate this may be a proper first option in selected patients. In cases of VUR secondary to neurogenic bladder dysfunction it seems to be less successful, probably because of a worse control of the high bladder pressure.

Eficacia del tratamiento endoscópico del reflujo vesicoureteral secundario. Análisis de una serie de 142 casos / The efficacy of endoscopic treatment for secondary vesicoureteral reflux. Analysis of a series of 142 cases

Objetivo: Analizar la proporción de reflujos vesicoureterales secundarios o complicados del total de reflujos vesicoureterales tratados en nuestro centro. Determinar la eficacia del tratamiento endoscópico en dicho tipo de reflujo según la etiología que lo produce y según el grado. Método: Revisamos nuestra serie desde que iniciamos el tratamiento endoscópico del reflujo en el año 1992 hasta diciembre del 2006, empleando tres materiales distintos: pasta de politetrafluoroetileno (Teflon®), polidimetilsiloxano (Macroplastique®) y dextranómero-copolímero de ácido hialurónico (Deflux®). Hemos tratado a 402 pacientes y 479 unidades excretoras, de los que 124 pacientes y 142 unidades excretoras correspondían a una etiología secundaria. Se han seguido de forma sistemática mediante ecografía y CUMS o cistografía isotópica. Definimos el éxito del tratamiento como la desaparición del RVU o el descenso a grado I sin ITU tras retirar la profilaxis antibiótica. Resultados: Se resolvieron en el primer intento el 71,13% de los reflujos secundarios, mejorando al 85,92% en el segundo intento y al 90,14% en el tercero. El volumen medio inyectado ha sido de 0,65 ml. La tasa de complicaciones ha sido del 0%. Conclusiones: El tratamiento endoscópico del reflujo vesicoureteral secundario es un procedimiento minimamente invasivo, que puede realizarse en regimen ambulatorio, técnicamente algo más difícil que en los casos de reflujo vesicoureteral primario, pero con muy baja morbilidad y muy eficaz en casos seleccionados, por lo que pensamos que debe ser considerado la primera opción de tratamiento. La menor eficacia la hemos obtenido en los casos de reflujos secundarios a vejiga neurógena, probablemente en relación a un mal control de las altas presiones vesicales (AU)
