OSA in military veterans suffering from PTSD presents more often with insomnia than obesity or increased daytime sleepiness. These findings are different from those typically seen in non-PTSD veterans with OSA.
Several studies have estimated breast cancer risk in patients with systemic lupus erythematosus (SLE) relative to the general population. However, the results have been inconclusive. Therefore, we conducted a meta-analysis to ascertain a more comprehensive conclusion. A systematic literature search of electronic databases including PubMed, Web of Science, Embase, Cochrane Library, and Scopus was conducted to identify eligible studies using multiple search strategies. Based on the degree of heterogeneity, a random-effect model was chosen to calculate the pooled standardized incidence rate (SIR) with 95% confidence interval (CI), to estimate the strength of association between SLE and breast cancer incidence risk. A total of 18 eligible studies including 110,720 patients with SLE were enrolled in this meta-analysis. The combined results showed no significant association between SLE and breast cancer incidence (SIRs = 1.012 (95% CI, 0.797-1.284)). Subgroup analysis by study type, ethnicity, follow-up years, sample size, and SLE diagnostic criteria also showed no altered risk for breast cancer incidence (the summary risk estimate of each subgroup ranged from 0.82 to 1.40 with no statistical significance). This meta-analysis suggests no direct association between SLE and risk of breast cancer incidence.
Management of children with acute gastroenteritis is based upon dehydration estimation. There is no clinical or paraclinical tool which exactly estimates the dehydration degree. Recently ultrasonographic parameters as inferior vena cava (IVC) diameter and aorta (AO) have been used in some studies for this purpose. This study aims to evaluate the efficacy of ultrasound in detecting mild and moderate degrees of dehydration in children. The study was performed in the emergency department of Dr. Sheikh’s Children Hospital, Mashhad, Iran. Children with mild to moderate degrees of dehydration according to World health Organization (WHO) clinical scale were enrolled. Their inferior vena cava diameters, aorta and IVC/AO ratio were measured before and after fluid therapy using ultrasound. Ultrasound was performed by two pediatric sonographers. 36 patients (mean age of 16.94±11.02 months) entered the study. 11 patients had mild and 25 moderate dehydration according to WHO clinical scale. All 11 patients with mild dehydration received oral rehydration. 13 patients in the moderate dehydration group received intravenous rehydration because of oral intolerance to fluids and recurrent vomiting. IVC diameter and IVC/AO ratio after fluid therapy in children with both mild and moderate dehydration degrees was significantly greater (P<0.001). However, we did not observe any significant difference in aorta diameter before and after fluid therapy. Using Receiver Operating Characteristic (ROC) curve, the proper cut-off point of IVC/AO ratio to differentiate patients with moderate dehydration from mild dehydration is equal to 0.782 with sensitivity and specificity equal to 88% and 45.45% respectively. Further, the area under the ROC curve for this cut-off is equal to 0.569. In conclusion, ultrasonography cannot differentiate between mild and moderate dehydration degrees, but studies with larger population of patients should be performed.
SUMMARYObjectivesThe objective of this study is to evaluate the effect of rapid intravenous rehydration to resolve vomiting in children with acute gastroenteritis.MethodsThis randomized control trial was conducted in the pediatric emergency department in a tertiary care center in Tabriz, North-West of Iran. The study participants' were 150 children with acute gastroenteritis and vomiting who were moderately dehydrated, had not responded to oral rehydration therapy and without any electrolyte abnormalities. 20–30 cc/kg of a crystalloid solution was given intravenously over 2 hours and the control group was admitted in the emergency department (ED) for a standard 24 hour hydration. Effectiveness of rapid intravenous rehydration in the resolution of vomiting in children with acute gastroenteritis was evaluated.ResultsIn 63 children of the intervention group (out of 75) vomiting was resolved after rapid IV rehydration and they were discharged. Among them, 12 that did not tolerate oral fluids were admitted. In the control group, 62 patients' vomiting was resolved in the first 4 hours after admission, and there was no significant difference between the two groups regarding resolution of vomiting.ConclusionsRapid intravenous rehydration in children with moderate dehydration and vomiting due to gastroenteritis is effective in reducing admission rates in the ED.
BackgroundThe 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.ObjectiveTo determine the challenges of the OSCE National Board Exam in Iran.MethodsThis 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.ResultsFourteen 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.ConclusionSome 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.
Desmopressin and oxybutynin combination therapy is more effective than desmopressin monotherapy for treating children with enuresis.Please cite this paper as: Ravanshad Y, Azarfar A, Ghalegolab-Behbahan A, Mortazavi F, Ahmadzadeh S, Ghorat F, et al.Comparing the efficacy of desmopressin and oxybutynin combination therapy and desmopressin monotherapy in children with primary nocturnal enuresis; a randomized clinical trial.
Background:Voiding Cystourethrography (VCUG) is the gold standard of detecting and grading the vesicoureteral reflux. Moreover, VCUG is a part of the standard review for infants and children with a urinary tract infection and urinary dysfunction.Objectives:The purpose of our study was to compare using oral midazolam in contrast to prescribing no sedative medication for voiding dysfunction in children undergoing VCUG.Patients and Methods:In a clinical trial, we studied 84 children referred for VCUG. Children were allocated randomly into two equal groups. The intervention group received 0.5 mg/kg midazolam orally half an hour before the VCUG procedure. Then both groups were compared using statistical methods.Results:Then both groups were compared using statistical methods. In more than half of the patients, the main cause of performing VCUG was urinary tract infection. Dysuria was evaluated immediately after VCUG and was more frequent in girls than in boys (P = 0.006). After one week, the urinary irritation and restlessness in the intervention group was significantly lower than the control group.Conclusion:The use of midazolam 0.5 mg/kg reduced children's stress and increased their cooperation during the procedure.
