RESUMEN

Introducción: La mayoría de las guías recomiendan realizar una cistografía miccional (CUMS) temprana tras el tratamiento endoscópico del reflujo vesicoureteral (RVU), pero no hay consenso sobre cómo hacer el seguimiento a largo plazo en este grupo de pacientes. El objetivo de este estudio es analizar si es necesaria la realización de una CUMS tardía en aquellos pacientes tratados con éxito. Material y método: Hemos revisado las historias clínicas de aquellos pacientes tratados de RVU con el copolímero de dextranómero/ácido hialurónico (Dx/AH) desde 2006 a 2010. Se han seleccionado aquellos pacientes que estaban curados tras el tratamiento con más de 3 años de seguimiento y control cistográfico tardío. Hemos analizado los hallazgos clínicos y radiológicos a largo plazo. Resultados: Ciento sesenta niños con 228 uréteres refluyentes recibieron tratamiento con Dx/AH con un seguimiento medio de 52,13 meses. A 215 se les realizó CUMS de forma temprana, siendo la tasa de éxito del 84,1%. El grupo de estudio fueron 94/215 uréteres refluyentes que tuvieron un seguimiento clínico y cistográfico tardío mayor de 3 años. En el 79,8% la CUMS mostró ausencia de RVU, siendo la tasa de éxito tardío clínico del 91,7%. La incidencia de infección del tracto urinario febril entre aquellos que estaban curados desde el punto de vista radiológico frente a aquellos en los que recidivó el RVU fue del 8 y 15%, respectivamente. Solo existieron diferencias significativas en la recidiva del RVU entre aquellos uréteres que se habían tratado de forma inicial con una punción o con 2 punciones de Dx/AH. Conclusión: Si el objetivo del tratamiento del RVU es disminuir las infecciones del tracto urinario febril, no es necesario realizar una CUMS tardía tras un tratamiento exitoso inicial con Dx/AH, a pesar de que la tasa de éxito radiológico es menor que la del clínico

Introduction: Some guidelines recommend an early voiding cystourethrography (VCUG) after endoscopic treatment of vesicoureteral reflux (VUR), but there's no consensus if it's necessary a long-term follow-up in these patients. The aim of our study is analyze if it's necessary a delayed VCUG after initial successful treatment with Dx/HA. Material and method: We have reviewed all medical charts of patients that underwent Dx/HA treatment from 2006 to 2010. We have selected patients with initial successful treatment and more than 3 years of radiological and clinical follow-up. We have analyzed late clinical and radiological outcomes. Results: One hundred and sixty children with 228 refluxing ureters underwent Dx/HA endoscopic treatment with a mean follow-up of 52.13 months. Early VCUG was performed in 215 ureters with an initial successful rate of 84.1%. The group of study was 94/215 ureters with more than 3 years of follow-up with a delayed VCUG. VUR was still resolved in 79,8% of the ureters. Clinical success rate was 91.7%. The incidence of febrile urinary tract infection in those patients with cured VUR and those with a relapsed VUR was 8 and 15%, respectively; but there were no significant differences. We have not found any variable related with relapsed VUR except those ureters that initially received 2 injections (P < .05). Conclusion: If our objective in the treatment of VUR is to reduce the incidence of febrile urinary tract infection it is not necessary to perform a delayed VCUG even though the long-term radiological outcomes is worse than clinical outcome

RESUMEN

Subcutaneous fat necrosis (SCFN) is a rare entity that occurs generally in term or post-term newborns exposed to perinatal stressing factors. These cutaneous lesions appear during the first weeks of life and their potential complications, such as hypercalcemia, determine the prognosis. We present a full-term newborn with SCFN lesions that appeared at the age of 12 days and who, 1 week later, developed moderate hypercalcemia. In our patient, the standard treatment was not enough to normalize calcemia and, in order to prevent secondary effects, etidronate therapy was initiated and it successfully normalized calcium levels. When SCFN is diagnosed, it is important to detect early hypercalcemia and treat it aggressively. This case provides further evidence of etidronate as an alternative and effective treatment for moderate-severe hypercalcemia.

RESUMEN

Introducción: Se ha descrito una asociación entre neumonía y glomerulonefritis aguda iniciándose ambos procesos de forma simultánea. Pacientes y métodos: Estudio retrospectivo de 6 pacientes ingresados en nuestro centro entre los años 2001 y 2010 con glomerulonefritis aguda asociada a neumonía concomitante, con frotis y cultivo amigdalar negativos y en ausencia de infección cutánea o episodio de neumonía anterior. Resultados: La media de edad de los pacientes al ingreso fue de 5,9 años sin diferencia de sexos. El diagnóstico de neumonía se realizó en el momento del ingreso, coincidiendo con la sintomatología nefrológica. Los síntomas más frecuentes fueron fiebre y hematuria macroscópica. Todos tuvieron un C3 (fracción C3 del complemento) bajo. En 5 de ellos se encontró una elevación significativa en la cifra de antiestreptolisinas (ASLO). En la mayoría de los casos la afectación renal fue leve a excepción de un caso de insuficiencia renal aguda con creatinina inicial de 2,77 mg/dl y filtrado glomerular de 27 ml/min/1,73m2 y 2 casos con proteinuria en rango nefrótico. Todos evolucionaron hacia la curación sin tratamiento o con mínimo tratamiento diurético o hipotensor, además de tratamiento antibiótico adecuado para su proceso neumónico, con resolución de la clínica entre 7—10 días y normalización del C3 en un período inferior a los 4 meses. Conclusiones: Aunque descrita con mucho menos frecuencia, existe asociación entre glomerulonefritis aguda y presencia concomitante de neumonía. Las ASLO, en nuestra serie, no son específicas de infección por Streptococcus pyogenes. El pronóstico respiratorio y renal fue favorable en todos los casos (AU)

Introduction: There is an association between pneumonia and acute glomerulonephritis. Both processes start simultaneously. Patients and methods: A retrospective study of 6 patients admitted to our centre between 2001 and 2010 with acute glomeruolonephritis associated with pneumonia. The result of the smear and tonsil culture was negative and there was an absence of cutaneous infection. Results: The average age of the patients on admission was 5.9 years with no differences in sex. The diagnosis for pneumonia was made at the time of admission, coinciding with the glomerular symptoms. The most frequent symptoms were fever and macrohaematuria. All had low levels of C3. A significant increase in ASLO was found in 5 cases. The majority of the cases had mild symptoms with the exception of one case of acute renal failure with an initial creatinine of 2.77 mg/dL and glomerular filtration rate of 27 ml/min/1.73m2, and two cases with proteinuria in the nephrotic range. All of them progressed satisfactorily without treatment or with minimum diuretic or hypotensive treatment in addition to the appropriate antibiotic treatment with clinical resolution in 7 to 10 days, and C3 returning to normal within a period of less than 4months. Conclusions: There is an association between acute glomerulonephritis and pneumonia, although it is very uncommon. The ASLOs in our series are not specific for Streptoccocus. Pyogenes infection. The respiratory and renal prognosis was favourable in all cases (AU)

RESUMEN

Objetivos: Presentar nuestra experiencia sobre biopsias renales percutáneas guiadas ecográficamente en pacientes en edad pediátrica desde que se instauró dicha técnica en nuestro hospital, y valorar la correlación clínica/anatomopatológica y las complicaciones de la misma. Pacientes y métodos: Estudio retrospectivo de 180 biopsias renales percutáneas guiadas ecográficamente realizadas a un total de 164 pacientes (de 6 meses-18 años de edad) durante un periodo de 15 años. El protocolo de la biopsia incluye su realización en el quirófano mediante sedación y una ecografía a las 24 horas. Resultados: El motivo más frecuente de su realización fue la presencia de un síndrome nefrótico cortico dependiente/resistente (29,4%), seguido de la proteinuria de diverso rango con presencia de hematuria. El diagnóstico anatomopatológico más habitual fue la glomérulo nefritis mesangial por IgA (26,1%), seguido de cambios glomerulares mínimos, confirmándose en la mayoría de los casos la sospecha clínica. Únicamente se detectó una complicación grave (hematoma renal/hipotensión arterial)en un paciente de riesgo. Conclusiones: En nuestra experiencia, la biopsia renal percutánea es un método diagnóstico fiable y seguro, independientemente de la edad (AU)

Objectives: We present our experience on ultrasound guided percutaneous renal biopsies in pediatric patients from the beginning that this technique was established in our hospital, to value the clinical/anatomo pathologic correlation as well as the complications of the technique. Patients and methods: Retrospective study of 180 ultrasound guided percutaneous renal biopsies over a total of 164 patients (aged from 6 months to 18 years) in a period of 15 years. The protocol biopsy includes its carrying out in the operating room by means of sedation and also the realization of an ultrasound after 24 hours. Results: The most frequent reason for doing the biopsy was the presence of a corticoid dependent/resistant nephrotic syndrome (29.4%) followed by different levels of. The most frequent anatomopathological diagnostic was glomerulonephritis with Ig A mesangial deposits (26.1%) followed by minimal glomerular changes, confirming in the majority of the cases the initial clinical suspicion. Only in one case a severe complication was detected (renal hematoma/arterial hypotension) in a high-risk patient. Conclusions: In our experience, the percutaneous renal biopsies are a reliable and a safe diagnostic method regardless of age (AU)

RESUMEN

Posttransplant diabetes mellitus (PTDM) occurs in approximately 15% to 20% of renal transplant patients. It has important clinical implications for graft function and survival. Anticalcineurin drugs are associated with an increased risk of developing PTDM. There is a little evidence that conversion from tacrolimus to cyclosporine (CsA)-based immunosuppression improves glucose metabolism and reverses diabetes. This prospective study included nine renal transplant patients (mean age of 34 +/- 20) with PTDM under immunosuppression with tacrolimus. Five were switched directly to CsA and the other four (glycemia > 250 mg/dL) required insulin and were simultaneously switched to CsA. Basal blood levels of tacrolimus were 7.9 +/- 1.9 ng/dL. Conversion was associated with an early, significant improvement of glycemia and HbA1c blood levels (P < .01). At the end of the follow-up, the glycemia (105 +/- 20 mg/dL) and Hb1Ac (5.1 +/- 0.4 mg/dL) were normal. Insulin was discontinued between 3 and 6 months in all patients who required it at the beginning. Cholesterol did not change significantly and triglycerides decreased significantly (basal 210 +/- 85 mg/dL, at 12 months 125 +/- 29, P < .01). Graft function was stable with a mean serum creatinine of 1.7 +/- 0.2 mg/dL. CsA blood levels remained stable during all follow-up periods (P = NS). There were neither episodes of acute rejection nor secondary effects related to the medication. In summary, renal transplant patients receiving tacrolimus who develop PTDM may display better control of hyperglycemia by a switch to CsA.
