Introduction: Urinary tract infection (UTI) is one of the most common bacterial infections in children that can be associated with renal parenchymal injuries and late scars. Dimercaptosuccinic acid (DMSA) renal scan is known as golden standard for detecting acute pyelonephritis (APN) that has a lot of difficulties and limitations. Objectives: we designed this study the accuracy of one inflammatory marker, serum procalcitonin (PCT) to identify as an early predictor of renal injuries. Patients and Methods: A prospective study was carried out in 95 patients who admitted in the hospital with the first febrile UTI. Serum PCT of all patients was measured; sensitivity, specificity, positive and negative predictive value (PPV and NPV) of this marker was analyzed compared to DMSA scan. P value <0.05 was taken as significant. Results: In total, 79 females and 16 males were investigated. There are 42 cases in group 1 with normal DMSA scan and 53 patients in group two with renal parenchymal injuries in their scans. Mann-Whitney test showed a meaningful relation between the two groups regarding PCT level (P<0.0001). Sensitivity, specificity, PPV and NPV of PCT reported in optimum cut off were 70%, 88.1%, 88.1% and 70%, respectively. The positive likelihood ratio (PLR) of PCT test was 5.8. Conclusion: In the current survey, PCT was the eligible inflammatory marker to predict renal parenchymal injuries in children with proper sensitivity, specificity, PPV and NPV that play also a pivotal role in the children aged less than 24 months, although, more studies should be undertaken to confirm.
Background: Enuresis is bedwetting that occurs during sleep in children over five years old. If left untreated, it can lead to social and psychological problems for children and their parents. The role of copeptin in patients with primary monosymptomatic nocturnal enuresis (PMNE) has been reported in several studies. Due to the favorable structural properties of copeptin and the reflection of arginine vasopressin (AVP) concentration, it can be used as an alternative marker for AVP secretion. Objectives: This study aims to compare the levels of copeptin in healthy and enuresis children aged 5 - 15 years. Methods: This case-control study was performed on 42 children with primary monosymptomatic enuresis and 42 children without enuresis who were referred to the clinic of Taleghani hospital in Gorgan in 2020. Copeptin levels were measured by the enzyme-linked immunosorbent assay (ELISA) method. Results: Out of 84 patients, an equal proportion of girls (21 patients) and boys (21 patients) participated in both the case and control groups. The age of the children was 8.05 ± 2.46 years, and there was no statistically significant difference between the two groups (P = 0.16). The mean level of copeptin in the case and control groups were 6.7 ± 4.27 and 6.87 ± 8.52 pg/mL, respectively, significantly lower in the case group (P = 0.03). There was a statistically significant difference in the level of copeptin between the boys in the two groups (P = 0.03). Although the mean level of copeptin in the girls in the patient group was lower than that in the control group, this difference was not statistically significant (P = 0.35). Conclusions: In this study, the mean level of copeptin in PMNE was significantly lower than that in the control group, which suggests it may be considered as a probable biomarker for the prediction of response to treatment with desmopressin, but further study is required to confirm this hypothesis.
Golestan province in the northeast of Iran is part of the Asian esophageal cancer belt and is known as a high-risk area for esophageal (EC) and gastric cancers (GC).Data on incident cases of EC and GC during 2004 to 2018 were obtained from the Golestan Population-based Cancer Registry (GPCR). The age-standardized incidence rates (ASRs) were calculated and presented per 100 000 person-years.The estimated annual percentage change (EAPC) with 95% confidence interval (95% CI) were calculated. We also fitted age-period-cohort (APC) models to assess nonlinear period and cohort effects as incidence rate ratios (IRRs). Overall, 3004 new cases of EC (ASR = 15.7) and 3553 cases of GC (ASR = 18.3) were registered in the GPCR. We found significant decreasing trends in incidence rates of EC (EAPC = À5.0; 95% CI: À7.8 to À2.2) and less marked nonsignificant trends for GC (EAPC = À1.4; 95% CI: À4.0 to 1.4) during 2004 to 2018. There was a strong cohort effect for EC with a consistent decrease in the IRR across successive birth cohorts, starting with the oldest birth cohort (1924; IRR = 1.9 vs the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
