Dat...
[ 3 ] - Accuracy of Pediatric Emergency Care Applied Research Network Rules in Prediction of Clinically Important Head Injuries; A Systematic Review and Meta-Analysis
Objective: the present meta-analysis was designed to determine the value of Pediatric Emergency Care Applied Research Network (PECARN) rule in prediction of clinically important traumatic brain injury (ciTBI).Methods: Extensive search was conducted in the databases of Medline, Embase, Scopus, Web of Sciences, Cinahl up to the end of August 2017. The search records were screened and summarized b...
[ 4 ] - Efficacy of Neuromodulation in Fecal Incontinence in Children; A Systematic Review and Meta-Analysis
Background: The results of existing studies regarding the use of neuromodulation in fecal incontinence (FI) are contradictory and therefore, a definitive conclusion cannot be made in this regard. Therefore, the aim of the present study is to evaluate the effectiveness of neuromodulation in controlling FI in children through a systematic review.Methods: A decision was made to perform the search ...
[ 5 ] - Human Adipose-Derived Stem/Stromal Cells from Children or Adults?
Discovering a cell type with the highest efficiency and the least side-effects is one of the priorities of scientists active in this field. Of all the cells, mesenchymal stem cells have been and still are of interest to the researchers for use in pre-clinical and clinical studies due to being easily accessible, pluripotency, secretion of numerous growth factors, low risk of immunological reject...
[ 6 ] - Diagnostic Value of Technetium-99m-Dimercaptosuccinic Acid Scintigraphy in Prediction of Vesicoureteral Reflux in Children with First-time Febrile Urinary Tract Infection
Background: Imaging modalities such as voiding cystourethrography (VCUG), direct radionuclide cystography (DRNC), and renal cortical scintigraphy (RCS) with technetium-99m dimercaptosuccinic acid (Tc-99mDMSA), are helpful in detecting possible abnormalities of urinary tract such as vesicoureteral reflux (VUR). However, there are confounding data regarding the preference of these modalities. In ...
[ 7 ] - Prediction of Clinically Important Traumatic Brain Injury in Pediatric Minor Head Trauma; proposing Pediatric Traumatic Brain Injury (PTBI) Prognostic Rule
Background: The present study assesses independent predictors of clinically important traumatic brain injury (ciTBI) in order to design a prognostic rule for identification of high risk children with mild head injury. Materials and Methods: In a retrospective cross-sectional study, 3,199 children with mild traumatic brain injury (TBI) brought to emergency ward of three hospitals in Tehran, Iran...
[ 8 ] - Value of Plasma/Serum Neutrophil Gelatinase-Associated Lipocalin in Detection of Pediatric Acute Kidney Injury; a Systematic Review and Meta-Analysis
Background: Major attention has been drawn to the prognostic value of plasma/serum neutrophil gelatinase-associated lipocalin (NGAL) in detection of acute kidney injury (AKI) in children, but still no consensus has been reached. Accordingly, the present study aimed to assess the diagnostic value of this biomarker in detection of acute kidney injury in children through a systematic review and me...
[ 9 ] - Diagnostic Value of Urinary Neutrophil Gelatinase-Associated Lipocalin (NGAL) in Detection of Pediatric Acute Kidney Injury; a Systematic Review and Meta-Analysis
Background: Two questions about diagnostic value of urinary neutrophil gelatin associated lipocalin (uNGAL) in detection of acute kidney injury (AKI) in children have remained unanswered; first, which cut-off point of uNGAL has the highest value in detection of AKI; and second when is the best time for measuring this biomarker in a patient? Accordingly, the present study aimed to conduct a syst...
[ 10 ] - The Value of Serum Β-Subunit of Human Chorionic Gonadotropin Level in Prediction of Treatment Response to Methotrexate in Management of Ectopic Pregnancy; a Systematic Review and Meta-Analysis
Background: No consensus has been reached on prognostic value of serum concentration of β (beta) subunit of human chorionic gonadotropin (β-hCG) in treatment response to methotrexate in management of ectopic pregnancy. Therefore, the present study aimed to evaluate this subject through a systematic review and meta-analysis. Materials and Methods: An extensive literature search on online databas...
[ 11 ] - Etiology and Outcome of Chronic Kidney Disease in Iranian Children
Background Considering the significant geographical and ethnical differences in pattern of incidence, etiology and outcome of chronic kidney disease (CKD), the present study aimed to assess the etiology and outcome of CKD in Iranian children. Materials and Methods In a cross-sectional study etiology and outcome of 372 children aged 3 months to 18 years with CKD was studied during the period 199...
[ 12 ] - Blood Pressure Nomograms by Age and Weight for Iranian Children and Adolescents
Background: Normal standard references of blood pressure (BP) for children and adolescents have been suggested to be constructed based on anthropometric indices. Accordingly, we aimed to develop first BP reference percentiles by weight and age for Iranian children aged 3-18 years old. Materials and Methods: A total of 16,246 children and adolescents aged 3-18 years were included from 3 cross-se...
[ 13 ] - Body Mass Index Percentile Curves for 7 To 18 Year Old Children and Adolescents; are the Sample Populations from Tehran Nationally Representative?
Background: The children’s body composition status is an important indicator of health condition evaluated through their body mass index (BMI). We aimed to provide standardized percentile curves of BMI in a population of Iranian children and adolescents. We assessed the nationally representative of sample populations from Tehran. Materials and Methods: A total sample of 14,865 children aged 7-1...
[ 14 ] - Long-Term Survival of Peritoneal Dialysis in Children: A Cohort Study
