RESUMO
OBJECTIVE: This systematic review and meta-analysis aimed to explore rituximab (RTX) associated infectious complications in children with glomerular disease. METHODS: We performed an electronic search of PubMed, International Scientific Information (ISI), Scopus, and EMBASE between January 2010 and July 2021. Infection rates and total drug-related adverse events were the outcomes. Statistical heterogeneity was evaluated by using the I2 statistic. When there was statistical evidence of heterogeneity (I2 > 50%, p > 0.1), a random-effect model was adopted. Data analysis was performed with Stata17.0 software. RESULTS: A total of 7 studies with 668 patients (136 with lupus nephritis [LN] and 532 with nephrotic syndrome were included in the meta-analysis. The pooled risk ratio showed that the administration of RTX was significantly associated with lower risk of infectious complications in patients with LN and nephrotic syndrome (0.72 [95% CI 0.58, 0.85]) when compared with population data of patients without glomerular disease (p = 0.2). There was no significant difference between the LN and nephrotic syndrome groups in terms of total serious adverse events or the occurrence of infections. There was significant heterogeneity among the reported studies (Q = 42.39, p < 0.001, I2 = 81%). CONCLUSION: Administration of RTX in children with glomerular disease is associated with a lower rate of infections when compared with population data of patients without LN or nephrotic syndrome. Additional high-quality randomized controlled trials with long-term follow-up are needed to identify the long-term potential complications.

RESUMO
Angiotensin receptor blockers (ARBs) are commonly prescribed in pediatric hypertension because of the fundamental role of the renin-angiotensin-aldosterone system in the pathogenesis of hypertension. We, therefore, aimed to systematically review articles that investigated efficacy and safety of ARB agents in the pediatric population aged over six years. To do so, the databases of Web of Science, PubMed/MEDLINE, and Scopus were searched to conduct a systematic review by using the following keywords: ("angiotensin receptor blocker" OR "valsartan" OR "losartan") AND ("pediatric" OR "children" OR "child") AND ("high blood pressure" OR "hypertension"). Finally, 12 studies were included in our review, and we found that almost all of them supported the effectiveness and tolerability of different ARB agents. Candesartan cilexetil lowered blood pressure (BP), with a 9 mmHg decline in both systolic and diastolic BP, and proteinuria after four months of treatment. Valsartan and Losartan similarly were shown to be effective in lowering BP in a dose-dependent manner. Headache, dizziness, upper respiratory infection, and cough were the most reported side effects. However, almost all reviewed studies indicated that the safety profile was satisfactory. In conclusion, ARBs are beneficial and well-tolerated antihypertensive medications. DOI: 10.52547/ijkd.7228.

OBJECTIVE: To study the cardiac outcomes of patients with multisystem inflammatory syndrome in children (MIS-C) after 6-month of diagnosis. METHODS: This review of hospital records was conducted on MIS-C patients (aged <21 year) who completed a six-month follow up. The baseline demographic, clinical, laboratory, and treatment characteristics during the acute phase, and echocardiographic findings during follow-up were collected. RESULTS: 116 patients (61.2% male, median age 7 years) with MIS-C were included in the study. At the time of admission, cardiac abnormalities were present in 70.7% of MIS-C patients, and the most common cardiac abnormalities were valve failure (50.9%), followed by ventricular dysfunction (39.7%), and pericardial effusion (23.3%). Six month after diagnosis, cardiac abnormalities were found in 10.3% of patients, and patients had lower rates of ventricular dysfunction (P<0.001), valve failure (P<0.001), pericardial effusion (P<0.001), and coronary involvement (P<0.001) as composed to the baseline. Intravenous immunoglobulin (IVIG) and steroid treatment significantly reduced the odds of occurrence of ventricular dysfunction (P=0.002), valve failure (P=0.004), and low ejection fraction (P=0.002) in comparison to IVIG treatment. CONCLUSION: While most MIS-C patients had abnormal echocardiographic findings at admission, only 10.3% of patients had cardiac abnormalities during follow up.

OBJECTIVE: Current conventional formulas do not predict the expected changes in serum sodium after administration of various fluids to correct serum sodium abnormalities. The Adrogué-Madias formula is currently the preferred and widely used fluid prescription for adult patients with dysnatremias, but its therapeutic efficacy has not been validated in pediatric patients. METHODS: In this prospective study, we used the Adrogué-Madias formula for calculating the appropriate rate of various fluids administration to correct serum sodium abnormalities in 7 critically ill children with acute dysnatremias. RESULTS: After administration of various intravenous fluids using the Adrogué-Madias formula, the anticipated as well as the achieved sodium concentrations were almost similar. CONCLUSIONS: This study demonstrates that the use of the Adrogué-Madias quantitative formula allows to calculate the appropriate rate of administration of various fluids. The calculated fluid administration resulted in the subsequent actual laboratory values and clinical changes.

The newest Kidney Disease Improving Global Outcomes (KDIGO) guideline recommendations were investigated mainly for the care of adult kidney transplant recipients, but no guideline exists for the management of pediatric transplant recipients. This review provides update recommendations in the management of pediatric kidney transplantation. Four electronic databases, PubMed, EMBASE, Google Scholar, and Web of Science were searched systematically for the last two decades, using Mesh terms in English language. The Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach was used for grading the quality of the overall evidence and the strength of recommendations for each outcome across the studies. The overall quality of evidence categorized as high (A), moderate (B), low (C), or poor (D). The strength of a recommendation was determined as level 1 (recommended) or level 2 (suggested). The ungraded statements were determined on the basis of common sense to provide general advice. Of the 317 citations which were screened for the evidence review, 62 were included in data extraction. The included studies were randomized controlled trials, prospective cohorts and cross-sectional, descriptive, and review studies. Of the 115 statements, 56 (48.6%) were graded 1 (we recommend), 34 (29.5%) were graded 2 (we suggest), and 25 (21.7%) were ungraded statements. Altogether, only 22 (19.1%) of recommendations reached the "A" or "B" levels of quality of evidence. The pediatric kidney transplant recipients are different from adult recipients regarding the primary kidney diseases, surgical techniques, drug metabolism, adherence to medications, growth and neurocognitive development and immunization needs prior to transplantation.

Background: Steroid resistant nephrotic syndrome (SRNS) represents a significant renal disease burden in childhood and adolescence. In contrast to steroid sensitive nephrotic syndrome (SSNS), renal outcomes are significantly poorer in SRNS. Over the past decade, extensive genetic heterogeneity has become evident while disease-causing variants are still only identified in 30% of cases in previously reported studies with proportion and type of variants identified differing depending on the age of onset and ethnical background of probands. A genetic diagnosis however can have implications regarding clinical management, including kidney transplantation, extrarenal disease manifestations, and, in some cases, even causal therapy. Genetic diagnostics therefore play an important role for the clinical care of SRNS affected individuals. Methodology and results: Here, we performed NPHS2 Sanger sequencing and subsequent exome sequencing in 30 consanguineous Iranian families with a child affected by SRNS with a mean age of onset of 16 months. We identified disease-causing variants and one variant of uncertain significance in 22 families (73%), including variants in NPHS1 (30%), followed by NPHS2 (20%), WT1 (7%) as well as in NUP205, COQ6, ARHGDIA, SGPL1, and NPHP1 in single cases. Eight of these variants have not previously been reported as disease-causing, including four NPHS1 variants and one variant in NPHS2, ARHGDIA, SGPL1, and NPHP1 each. Conclusion: In line with previous studies in non-Iranian subjects, we most frequently identified disease-causing variants in NPHS1 and NPHS2. While Sanger sequencing of NPHS2 can be considered as first diagnostic step in non-congenital cases, the genetic heterogeneity underlying SRNS renders next-generation sequencing based diagnostics as the most efficient genetic screening method. In accordance with the mainly autosomal recessive inheritance pattern, diagnostic yield can be significantly higher in consanguineous than in outbred populations.
RESUMO
INTRODUCTION: Kidney biopsy is a procedure of choice for the diagnosis of many kidney diseases. In children it is performed with the use of sedatives. The aim of this study was to compare the combination of propofol/fentanyl with midazolam/ketamine for sedation in pediatric patients undergoing kidney biopsy. METHODS: In this double-blinded clinical trial, seventeen children, candidate of kidney biopsy were included and randomized into two groups. One group received Midazolam/Ketamine with doses of 30 to 50 µg/kg and 0.25 to 1 mg/kg, and the other group were sedated with propofol/fentanyl combination in doses of 0.5 to 1 mg/kg and 0.5 to 1 mg/kg, respectively. Administration time, medication doses, total procedure time, need for analgesic use after the procedure, and patient relaxation, with no agitation during and after the biopsy were recorded. RESULTS: Nine patients received midazolam/ketamine and eight received propofol/fentanyl. None of them experienced vomiting or itching after sedation. There were no meaningful differences in qualitative variables of the need for pain relief between two groups. Regarding the distribution of pain at the time of sedation, and 1, 3, 6, and 24 hours after sedation, there was no significant statistical difference between the two groups. There was also no significant statistical difference between the two groups, regarding patients' relaxation during, and 1, 3, 6, and 24 hours after biopsy. CONCLUSION: There was no statistically significant difference between the degree of sedation and the analgesic effect of the two regimens in the two groups. DOI: 10.52547/ijkd.6982.

BACKGROUND: Therapeutic apheresis has been used in treating hematological and non-hematological diseases. For a successful procedure, efficient vascular access is required. Presently, peripheral venous access (PVA), central venous catheterization (CVC), implantable ports, and arteriovenous fistulas (AVFs) are used. This review aims to evaluate different type of access and their pros and cons to help physicians determine the best venous access. METHODS: The electronic search included PubMed and Google Scholar up to November 2020. The Mesh terms were apheresis, peripheral catheterization, central catheterization, and arteriovenous fistula. RESULTS: A total of 228 studies were found through database searching. Two independent authors reviewed the articles using their titles and abstracts; 88 articles were selected and the full text was reviewed. Finally, 26 were included. The inclusion criteria were studies incorporating patients with any indication for apheresis. CONCLUSION: PVA has been promoted in recent years in many centers across the United States to lower the rate of complications associated with vascular access and to make this procedure more accessible. Several factors are involved in selecting appropriate venous access, such as the procedure's duration and frequency, patient's vascular anatomy, and staff's experience. In short-term procedures, temporary vascular access like PVA or CVC is preferred. Permanent vascular access such as AVF, tunneled cuffed central lines, and implantable ports are more beneficial in prolonged treatment period but each patient has to be evaluated individually by apheresis team for the most appropriate method.

BACKGROUND: Children undergoing hemodialysis (HD) via arteriovenous fistula (AVF) experience approximately 300 painful punctures per year which may lead to non-compliance with HD. This study was conducted to show the effect of local anesthetics on pain perception in AVF cannulation. METHODS: This randomized clinical trial included 20 children under HD via AVF in Sheikh Children's Hospital Hemodialysis Center in February 2014. The first intervention was conducted as the baseline pain assessment (control), then every patient randomly received all three other interventions: Lidocaine gel, lidocaine spray, and needle plate, before venipuncture. Pain perception was expressed and recorded by patients using the visual analogue scale (VAS). VAS scores were compared, and a P value of <0.05 was considered significant. RESULTS: The VAS mean in lidocaine spray state, lidocaine gel state, and needle plate state was respectively 47.87, 51.31, and 49.43, which were significantly less than the control state with the VAS mean of 60.06 (lidocaine spray vs. control P value = 0.001, lidocaine gel vs. control P value = 0.001, and needle plate vs. control P value = 0.003). CONCLUSION: Our study showed that the use of needle plate, lidocaine spray, and lidocaine gel are all equally effective ways in controlling the degree of pain in AVF needling in children undergoing HD.
RESUMO
INTRODUCTION: There are some randomized trials which have already evaluated different calcineurin inhibitors (CNIs), especially comparing Tacrolimus and Cyclosporine, as immunosuppressant agents in children. However, their findings have been occasionally conflicting and thus debatable. Therefore, the evidence on safety and efficacy of immunosuppressive therapy after kidney transplantation in children has been inconclusive and argued to date. This study was aimed to compare the benefits and disadvantages of tacrolimus versus cyclosporine as the primary immunosuppression after renal transplantation in children. METHODS: A systematic review and meta-analysis was done. An electronic literature review was conducted to identify appropriate studies. The outcomes were presented as relative risk, with 95% confidence intervals. RESULTS: Five qualified randomized controlled trials were included in this systematic review. Tacrolimus was insignificantly superior to cyclosporine considering the total effect size of graft loss (RR = 0.67, 95% CI: 0.40 - 1.11; P > .05) and acute rejection (RR = 0.79, 95% CI: 0.59 - 1.05; P > .05). On the contrary, cyclosporine seemed to be insignificantly superior to tacrolimus regarding mortality rate (RR = 1.06, 95% CI: 0.59 - 1.90; P > .05). CONCLUSION: Admitting the study limitations mainly because of the nature and case study size of the included trials, it can be concluded from our systematic review results that Tacrolimus seems insignificantly superior to Cyclosporine respecting graft loss and acute rejection. However, Cyclosporine was shown to be insignificantly superior regarding mortality rate. However additional studies with a larger sample size are highly recommended.

INTRODUCTION: Nocturnal enuresis is a condition, which can affectthe quality of life in children. The present study was designed toinvestigate the efficacy of low-dose imipramine combined withdesmopressin on treatment of patients with primary nocturnalenuresis who were defined as desmopressin non-responders. METHODS: A randomized clinical trial was carried out on patientswith primary nocturnal enuresis. Forty children with enuresisranging from 5 to 12 years old were randomly divided into theintervention (n = 20) and control groups (n = 20). The subjects inthe intervention group were treated with desmopressin combinedwith 5 mg imipramine at bedtime, and those in the control groupwere given desmopressin alone. The patients were followed upweekly for one month. The number of wet nights was recorded. RESULTS: Two individuals in the intervention and three individualsin the control group were excluded from the study. Our findingsindicated that the age and gender showed no significant difference.Furthermore, a significant better recovery in the enuresis wasobserved in 18 of 20 patients who were treated with combinationtherapy after 1 month (P < .05). In addition, the frequency ofrecovery was significantly higher (83.3%) in the intervention group,compared with the control group (29.4%). CONCLUSION: The analysis showed that low-dose imipramine is welltolerated in clinical practice and may represent a good short-termtreatment option in combination therapy where desmopressinalone is not efficient enough.

Background: Nephropathic Cystinosis, the most common cause of renal Fanconi syndrome, is a lysosomal transport disorder with an autosomal recessive inheritance pattern. A large number of mutations in CTNS have been identified as causative to date. A 57 kb deletion encompassing parts of CTNS is most commonly identified in Caucasians but this allele has not been identified in individuals of Eastern Mediterranean, Middle Eastern, Persian, or Arab origin to date. Methods and Results: Implementing whole exome sequencing (WES) in a consanguineous Iranian family, we identified this large deletion affecting CTNS in a patient initially presenting with hypokalemic metabolic alkalosis symptoms and considerable proteinuria. Conclusion: We show WES is a cost and time efficient genetic diagnostics modality to identify the underlying molecular pathology in Cystinosis individuals and provide a summary of all previously reported CTNS alleles in the Middle east population. Our work also highlights the importance to consider the 57-kb deletion as underlying genetic cause in non-European populations, including the Middle East. Limited diagnostic modalities for Cystinosis in developing countries could account for the lack of previously reported cases in these populations carrying this allele. Further, our findings emphasize the utility of WES to define genetic causes in clinically poorly defined phenotypes and demonstrate the requirement of Copy number variation (CNV) analysis of WES data.
RESUMO
BACKGROUND: Bartter Syndrome is a rare, genetically heterogeneous, mainly autosomal recessively inherited condition characterized by hypochloremic hypokalemic metabolic alkalosis. Mutations in several genes encoding for ion channels localizing to the renal tubules including SLC12A1, KCNJ1, BSND, CLCNKA, CLCNKB, MAGED2 and CASR have been identified as underlying molecular cause. No genetically defined cases have been described in the Iranian population to date. Like for other rare genetic disorders, implementation of Next Generation Sequencing (NGS) technologies has greatly facilitated genetic diagnostics and counseling over the last years. In this study, we describe the clinical, biochemical and genetic characteristics of patients from 15 Iranian families with a clinical diagnosis of Bartter Syndrome. RESULTS: Age range of patients included in this study was 3 months to 6 years and all patients showed hypokalemic metabolic alkalosis. 3 patients additionally displayed hypercalciuria, with evidence of nephrocalcinosis in one case. Screening by Whole Exome Sequencing (WES) and long range PCR revealed that 12/17 patients (70%) had a deletion of the entire CLCNKB gene that was previously identified as the most common cause of Bartter Syndrome in other populations. 4/17 individuals (approximately 25% of cases) were found to suffer in fact from pseudo-Bartter syndrome resulting from congenital chloride diarrhea due to a novel homozygous mutation in the SLC26A3 gene, Pendred syndrome due to a known homozygous mutation in SLC26A4, Cystic Fibrosis (CF) due to a novel mutation in CFTR and apparent mineralocorticoid excess syndrome due to a novel homozygous loss of function mutation in HSD11B2 gene. 1 case (5%) remained unsolved. CONCLUSIONS: Our findings demonstrate deletion of CLCNKB is the most common cause of Bartter syndrome in Iranian patients and we show that age of onset of clinical symptoms as well as clinical features amongst those patients are variable. Further, using WES we were able to prove that nearly 1/4 patients in fact suffered from Pseudo-Bartter Syndrome, reversing the initial clinical diagnosis with important impact on the subsequent treatment and clinical follow up pathway. Finally, we propose an algorithm for clinical differential diagnosis of Bartter Syndrome.

OBJECTIVE: The associations between Gly71Arg polymorphism in the coding region of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) gene and the risk of neonatal hyperbilirubinemia remained controversial. Therefore, a meta-analysis of observational studies has been conducted to assess the relationship between UGT1A1 gene polymorphism of Gly71Arg and neonatal hyperbilirubinemia susceptibility. METHODS: An electronic literature search from online databases, such as PubMed, Embase, Cochrane, and Scopus was conducted to identify eligible studies. The effect summary odds ratio (OR) with 95% confidence interval (CI) was used to estimate the strength of association in the fixed or random effects model, based on the absence or presence of heterogeneity. RESULTS: A total of 32 eligible studies involving 2634 cases of neonatal hyperbilirubinemia and 4996 controls were enrolled in this meta-analysis. The combined results showed that UGT1A1 Gly71Arg polymorphism was associated with an increased risk of neonatal hyperbilirubinemia in all genetic models (homozygote model: OR = 6.12, 95% CI = 4.42-8.46; heterozygote model: OR = 2.06, 95% CI = 1.82-2.33; dominant model: OR = 2.44, 95% CI = 2.03-2.93; recessive model: OR = 4.79, 95% CI = 3.48-6.59, and allelic model: OR = 2.37, 95% CI = 1.98-2.82). Subgroup analysis by ethnicity strongly validated this correlation in Asians but slightly in Caucasian population. CONCLUSIONS: This meta-analysis confirms that UGT1A1 Gly71Arg polymorphism significantly increases the risk of neonatal hyperbilirubinemia in Asian population, but results from the Caucasians were conflicting and further well-designed epidemiological studies are, therefore, required to more adequately assess this correlation.

Kidney transplantation is usually followed by immunosuppressive therapy to prevent early rejection and prolong graft survival. The calcineurin inhibitors (CNIs) represent the most commonly used agents. However, available evidence suggests the poor outcome over the long term, maybe be due to the potential nephrotoxicity associated with CNIs. Several randomized trials have compared tacrolimus (TAC) with cyclosporine, to find the optimal agent for renal transplantation; however, studies have shown conflicting results. The aim of this study was to systematically review and update the evidence for the benefits and harm of TAC versus cyclosporine as the primary immunosuppression after renal transplantation. The study was a systematic review and meta-analysis. An electronic literature search was conducted to identify appropriated trial studies. The outcomes were presented as relative risk (RR), with 95% confidence intervals (CI). Statistical analysis used was meta-analysis. Twenty-one eligible randomized controlled trials were included in this systematic review. TAC was significantly superior to cyclosporine considering the total effect size of graft loss (RR 0.089; 95% CI0.057-0.122, P <0.001), acute rejection (RR 0.638; 95% CI 0.571-0.713, P <0.001) and hypercholeste-rolemia (RR 0.634; 95% CI, 0.539-0.746, P <0.001). On the contrary, cyclosporine seemed to be significantly superior to TAC with regard to diabetes (RR 1.891; 95% CI 1.522-2.350, P <0.001). However, no significant differences between the two CNIs were found with regard to mortality, infection, and hypertension. The review indicates that TAC is significantly superior to cyclosporine regarding graft loss, acute rejection, and hypercholesterolemia, but cyclosporine seems to be significantly superior to TAC regarding diabetes. However, further large randomized trials are suggested.

OBJECTIVE: The aim of the present study was to determine the accuracy of pediatric residents in diagnosis of dehydration in children with gastroenteritis. METHODS: This was a cross-sectional study in Dr. Sheikh Hospital, affiliated with Mashhad University of Medical Sciences (Mashhad, Iran), in 2016. One hundred fifteen children aged 1 month to 14 years with gastroenteritis were included according to easy sampling. All patients were weighed. Dehydration was scored as mild, moderate and severe by pediatric residents according to Nelson standard table including pulse rate, blood pressure, blood skin supplement, skin turgor, fontanel, mucus membrane, tear respiration and urine output criteria. Patients were rehydrated and reweighed consequently. Percent loss of body weight (PLBW) was calculated and compared with dehydration score. Statistical analysis was performed using SPSS windows program version 19 (SPSS Institute, Inc., Chicago, IL, USA). RESULTS: Of the115 children, 65 patients were male (56.5%) with the median age of 14.5 months. The Kendall's tau-b and Spearman correlation coefficient for residents' estimation and PLBW were 0.18 and 0.23 respectively (p=0.01 and 0.12 respectively). The ICC between estimated dehydration and PLBW was 0.47. According to residents' estimation and gold standard, PLBW was 6.76% and 1.33%, respectively. The serum level of sodium, potassium, urea and creatinine were 141.8 mEq/L, 4.6 mEq/L, 34.45 mg/dL and 0.6 mg/dL, respectively. CONCLUSION: There is positive but weak correlation between residents' estimation and PLBW in patients with dehydration. It is necessary to enhance the educational level of pediatric residents to increase the accuracy of physical examination and decrease medical errors.

RESUMO
INTRODUCTION: Uremic pruritus is characterized by an uncomfortable and unlimited sensation which leads to scratch, which strongly reduces the quality of life. Pruritus is a common symptom in patients with end-stage renal disease. Various clinical trial studies have examined the effects of acupuncture and acupressure on treatment of uremic pruritus. This systematic review meta-analysis aimed to evaluate the effectiveness based on published studies. MATERIALS AND METHODS: An electronic literature search was conducted to identify appropriate trial studies. The results for continuous outcomes were presented as weighted mean difference, with 95% confidence intervals. RESULTS: A total of 5 articles, including 6 trials, were enrolled in this systematic review. Only 3 of the six trial studies used a visual analogue scale score for assessing pruritus and acupressure for intervention regime, which were considered for meta-analysis. The combined results showed that acupuncture or acupressure was effective in treatment of uremic pruritus (pooled mean difference, -1.994; 95% confidence interval, -2.544 to -1.445). CONCLUSIONS: This study confirms that using acupuncture and acupressure is effective in treatment of uremic pruritus. However, further vigorous studies are needed to verify these findings.

BACKGROUND: The national board exam for residents in Iran is held in two parts: Multiple-choice and Objective Structured Clinical Examination (OSCE). The OSCE is a suitable method for evaluation of residents' clinical qualifications. However, it requires experienced human resources, accurate planning, facilities and reliable evaluation tools. OBJECTIVE: To determine the challenges of the OSCE National Board Exam in Iran. METHODS: This cross-sectional study was conducted on all the final-year pediatrics and gynecology residents of Mashhad University of Medical Science, who participated in the board exam in September 2014. A questionnaire was designed to evaluate the residents' opinion on challenges of the OSCE. Data was analyzed with SPSS16. We used U Mann-Whitney test independent t-test, and Pearson correlation coefficient. RESULTS: Fourteen pediatrics and eleven gynecology residents participated. In the gynecology group, there was no significant statistical correlation between the individual marks and questionnaire scores. However, in the pediatrics group, there was a significant correlation (p=0.046, r=-0.763). Based on pediatrics residents' perspective, the main challenge of the OSCE part of the exam was the imbalance and disproportion between the allowed time and the task load in each exam stage. In other words, they believed that the tasks could not be fulfilled in the given time. In the gynecology group, the main challenge reported was the delay in announcing the exam results. In the pediatrics group, the main complaint was the disproportion of the allowed time and the task load in the exam stages. CONCLUSION: Some of the challenges of the board exam were associated with the examiners and the exam environment, and some of them were related to the home university where the candidates had studied. To solve the problems, both aspects should be considered.
RESUMO
BACKGROUND: Imaging of the kidneys and urinary tract has a significant and critical role for diagnosis of genitourinary system diseases. Although technological progress goes toward less invasive approaches, some of the current methods are still invasive and annoying. Voiding cystourethrography (VCUG) is the best and most accurate method for diagnosis and grading of vesicoureteral reflux. VCUG is a distressful procedure that gives serious anxiety and pain in a large proportion of children and fear for parents; therefore, using effective sedative drugs with the least side effects is necessary and should be considered. MATERIALS AND METHODS: In this review article, importance and efficacy of different drugs before catheterization VCUG be compared in the base of literature survey on EMBASE, PubMed, and Cochrane source. RESULTS: We found that the treatment should be based on nonpharmacological and pharmacological methods; nonpharmacological treatment includes the psychological preparation before procedures as a safety precaution with little or no risk modality, as well as reassuring support. The presence of parents during painful procedures cannot alleviate children distress. Pharmacological methods include oral midazolam (0.5 mg/kg) and intranasal use (0.2 mg/kg) that had been used 10 min before the procedure can effect on anterograde amnesia and sedation without considerable effect on accuracy and grade of reflux. Nitric oxide has a shorter recovery time versus midazolam but has a potential risk for deep sedation and may interfere with the child's voiding phase. CONCLUSION: In summary, oral midazolam of 0.5-0.6 mg/kg or 0.2 mg/kg intranasal is acceptable drug that can be used before VCUG.
