Calcified fibrous pseudotumor with Castleman disease

Simultaneous calcified fibrous pseudotumor (CFT) and Castleman disease (CD) is an extremely rare association. CD is an uncommon lymphoproliferative disease that can arise in various sites of the body, while CFT is a rare type of benign fibrous lesion that frequently affects children and young adults, occurring as solitary or multiple lesions throughout the human body. Both entities are rare and exhibit typical and diverse histomorphological features. We report the case of a 15-year-old female patient, who, at the age of 13 had a biopsy performed at an external medical center; however, after 4 months the lesion had regrown. This lesion was removed with a surgical operation; however, it regrew 2 years later and was removed a third time. The results of the latter two biopsies were the same: CFT accompanying CD. The histologic examination of the excised lymph node and the surrounding tissue showed hyalinized fibrous tissue containing dystrophic and psammomatous calcification. In this case, the hyaline vascular type of CD was found to be intertwined with a CFT, which hampered the differentiation of whether both entities emerged within the lymph node or if the CFT developed from the soft tissue and then involved the lymph node. Future studies involving larger case series will provide a more precise insight, which should serve to resolve the current uncertainty.

Asociación entre el reflujo vesicoureteral y la nefroesclerosis en las infecciones urinarias / Association of vesicoureteral reflux and renal scarring in urinary tract infections

Introducción. El objetivo del estudio fue investigar la relación entre reflujo vesicoureteral (RVU) y daño renal en pacientes con infección urinaria (IU) sin fiebre, primera IU febril e IU recurrente. El objetivo secundario, determinar si la proteína C-reactiva (PCR) actuaría como predictor de nefroesclerosis en las IU febriles. Población y métodos. Estudio prospectivo; pacientes pediátricos con IU sin fiebre, primera IU febril e IU recurrente. Los análisis de laboratorio de rutina incluyeron hemograma completo, urea, creatinina, análisis de orina completamente automatizado, urocultivo y PCR. Se realizó ecografía urológica luego del diagnóstico de IU, cistouretrografía miccional tras seis semanas y gammagrafía renal estática con ácido dimercaptosuccínico marcado con 99mTc tras seis meses a todos los participantes. Resultados. Participaron 47 niños con IU sin fiebre, 48 con primera IU febril y 61 con IU recurrente. Hubo una diferencia estadísticamente significativa entre los grupos respecto de RVU y nefroesclerosis (p= 0,001 y p= 0,011, respectivamente). También hubo una diferencia estadísticamente significativa respecto de nefroesclerosis entre los pacientes con y sin RVU (p= 0,001). Además, se estableció una diferencia estadísticamente significativa respecto de nefroesclerosis (p < 0,05) en los pacientes con PCR cinco veces mayor o menor que el valor de corte aceptado (5 mg/dl). Conclusión. La proporción de nefroesclerosis fue paralela a la frecuencia de RVU. Cuanto mayor era el grado de RVU, mayor era el daño renal. Se determinó una correlación positiva entre PCR elevada y nefroesclerosis, lo que señala esclerosis durante el diagnóstico de pielonefritis.

Introduction. The aim was to investigate the relationship between vesicoureteral reflux (VUR) and renal damage in non-febrile, febrile for the first time and recurrent urinary tract infection (UTI) patients. The secondary aim was to determine whether C-reactive protein (CRP) in febrile UTIs could be a predictor of renal scarring. Population and methods. This prospective study included non-febrile, febrile for the first time and recurrent pediatric UTI cases. The routine lab analyses comprised a complete blood count, urea, creatinine, fully automated urinalysis, urine culture and CRP analyses. All the participants were examined using urine ultrasonography subsequent to their UTI diagnosis, voiding cystourethrography (VCUG) after six weeks and Tc-99m dimercaptosuccinic acid (DMSA) static renal scintigraphy after six months. Results. There were included 47 children with non-febrile UTIs, 48 with first febrile UTIs and 61 with recurrent UTIs. A statistically significant difference was found among the groups in terms of VUR and renal scarring (p= 0.001 and p= 0.011, respectively). A statistically significant difference was also found in terms of renal scarring between patients with and without VUR (p= 0.001). Moreover, a statistically significant difference was also present in relation to renal scarring (p <0.05) in patients with five-fold lower or higher CRP values than the accepted cut-off value (5mg/dl). Conclusion. The ratio of renal scars detected was found to be parallel to the VUR frequency. The higher the VUR grade, the more renal damage was found. A positive correlation between elevated CRP and renal scarring was determined, indicating the presence of scarring during the diagnosis of pyelonephritis.

Hemorragia masiva: una complicación tardía del reemplazo de la gastrostomía endoscópica percutánea. A propósito de un caso / Massive hemorrhage: a late complication of replacement percutaneous endoscopic gastrostomy: case report

La gastrostomía endoscópica percutánea (GEP) se utiliza como alternativa de la alimentación enteral/nasoenteral en situaciones en las que la alimentación por vía oral a largo plazo no es eficaz o no se tolera. Se prefiere principalmente en pacientes con afecciones neurológicas y, además, como apoyo de la nutrición en pacientes con enfermedades cardíacas congénitas, fibrosis quística, enfermedad intestinal inflamatoria y diversas enfermedades orofaríngeas. Si bien la colocación es sencilla en comparación con muchos procedimientos invasivos, presenta complicaciones, que incluyen desde la infección de la herida hasta la muerte. La GEP exige personal médico experimentado, antibióticos profilácticos adecuados e información exhaustiva para los pacientes o sus familias sobre el procedimiento y los cuidados posteriores. Presentamos una complicación rara, aunque importante, que surgió durante el reemplazo de la sonda de gastrostomía después del método de "corte y empuje". El tope, que debe llegar hasta el extremo distal del estómago, se desplazó hacia arriba, hasta el esófago proximal, y causó una úlcera profunda en la mucosa esofágica y una hemorragia masiva.

Percutaneous endoscopic gastrostomy (PEG) is used as an alternative to enteral/nasoenteral feeding in situations where long-term oral feeding is ineffective or not tolerated. It is mostly preferred in patients with neurological conditions and also to support nutrition in patients with congenital heart diseases, cystic fibrosis, inflammatory bowel disease, and various oropharyngeal diseases. Although it is easily applicable compared to many invasive procedures, it has complications ranging from wound infection to death. PEG requires experienced medical personnel, appropriate prophylactic antibiotics and exhaustive information to the patients or their families about the procedure and subsequent care. We present a rare but important complication during the replacement of the gastrostomy tube subsequent to the "cut and push" method. The bumper portions, which should move to the distal end of the stomach, moved upwards to the proximal esophagus, caused a deep ulcer in the esophageal mucosa and a massive hemorrhage.
