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.

The platelet indices in pediatric patients with acute appendicitis.

Background: The diagnosis of Acute Appendicitis (AA) remains a problem in pediatric population. It has been suggested that Mean Platelet Volume (MPV) is lower in the patients with AA. The purpose of this study was to investigate the diagnostic value of platelet indices in pediatric AA cases. Methods: A retrospective case-controlled study was designed: 224 subjects were included in this study. All patients had been operated on in division of pediatric surgery at the Kars Government Hospital with the preliminary diagnosis of AA. 204 and 20 of these patients were pathologically diagnosed as AA (group 1) and normal appendix vermiformis (group 2), respectively. Platelet indices had been studied in the biochemistry laboratory of the hospital, before the surgery. Results: In group 1, platelet count, mean platelet volume, plateletcrit and platelet distribution width were 305 ± 94x103/μL; 7.37 ± 0.90 fL; 0,220 ± 0.057 % and 16.3 ± 0.5%, respectively. In group 2, platelet count, mean platelet volume, plateletcrit and platelet distribution width were 283 ± 85 103/μL; 7.60 ± 1.24 fL; 0.208 ± 0.045 % and 16.4 ± 0.7%, respectively. There was no statistically significant difference between the groups studied with regard to platelet indices (P>0.05). Conclusions: Our study showed that platelet indices have no diagnostic value in the diagnosis of AA at pediatric age group.

Assessment of effects of pre- and post-training programme for healthcare professionals about breastfeeding.

This retrospective study assessed the effects of pre- and post-training programme for healthcare professionals about breastfeeding. The study included 3,114 mothers who had children aged 1-72 month(s). Their knowledge and behaviours relating to breastfeeding were evaluated. The mothers were randomly divided into two groups: the 'before' group included 2,000 women who were not informed about breastfeeding, and the 'after' group comprised 1,114 women who had been informed about breastfeeding. 56.2% and 66.1% of the mothers started breastfeeding within 30 minutes after delivery, respectively, in the before and the after group (chi2 = 29.31, p < 0.001). 16.7% and 36.5% gave exclusive breastfeeding for six months (chi2 = 72.85, p < 0.001), and 28.5% and 23.7% stopped breastfeeding within the first five months (chi2 = 17.20, p = 0.002). Ninety-four percent delivered in a hospital or in a primary healthcare centre. Therefore, prenatal and postnatal breastfeeding education and support courses may improve a woman's chance of starting and continuing to breastfeed her baby. In terms of the number of antenatal check-ups, since the differences between the two groups were significant (chi2 = 390.67, p = 0.000), the importance of the training programme about breastfeeding was highlighted. Follow-up interventions after training are suggested.
