The aim of this study was to assess the predisposing factors and frequency of ptx among the low birth weight (LBW) premature infants, under mechanical ventilation. <br/>Methods: <br/>This cross sectional study was performed in 121 LBW intubated premature infants at neonatal intensive care unit of a children hospital in Rasht, Iran during 18 months. Birth weight, gestational age(GA), sex, mode of delivery, initial diagnosis, respirator settings, history of surfactant therapy or ptx, 5th minute apgar score were recorded in neonates with or without ptx. Univariate and multivariate regression analysis were done. <br/>Finding: <br/>A total of 42 (34.7%) of infants developed ptx. Mean GA of neonates with ptx (case group) was 30±2.42 W and in neonates without ptx (control group) was 30.17±2.95 W. Mean birth weight in case and control groups were 1330 ± 386gr and 1482 ± 507gr respectively. In case group 69% and in control group 50% were delivered by cesarean section. 54.8% of cases and 53.2% of control group were male. No mentioned items reached statistical significance. Respiratory distress syndrome was the most common lung pathology in both groups. The rate of ptx was higher in cases with low apgar score at 5th minute (P=0.006). Surfactant therapy decreased the incidence of ptx (P=0.023). After multivariate logistic regression analysis only low apgar score at 5th minute significantly increased the risk of ptx. <br/>Conclusion: <br/> The incidence of ptx in this study was slightly higher than other reports and this may be due to assessment of only LBW premature intubated neonates. After multivariate logistic regression analysis only low apgar score at 5<sup>th</sup> minute increased the risk of ptx significantly.Mashhad University of Medical SciencesIranian Journal of Neonatology2251-75104320131001Comparison of side effect of survanta and curosurf in decreasing mortality due to respiratory distress syndrome (RDS) in premature infants admitted in NICU of Ghaem Hospital On 2006-2008712174710.22038/ijn.2013.1747ENReza SaeediDepartment of pediatrics, School of Medicine, Mashhad university of medical sciences, Mashhad, Iran0000-0002-0075-5732Abdolkarim HamediDepartment of pediatrics, School of Medicine, Mashhad university of medical sciences, Mashhad, Iran0000-0002-1564-8972Ali JavadiDepartment of pediatrics, School of Medicine, Mashhad university of medical sciences, Mashhad, IranMahbobeh Gholami RobatsangiDepartment of Nursing, faculty member of neyshabur university of medical sciences, Neyshabur, IranShima Kaka DinparvarDepartment of pediatrics, School of Medicine, Mashhad university of medical sciences, Mashhad, IranJournal Article20131004Background: Using of natural and synthetic surfactant is a rescue treatment for respiratory distress syndrome. In Iran, Survanta and Curosurf are the most frequent used natural surfactant preparations. We compared the clinical response and safety of two surfactants poractant alpha (Curosurf) and beractant (Survanta) for treatment of respiratory distress syndrome (RDS) in preterm infants. <br/>Method:This study was a clinical trial study that performed during a 2-year period in Ghaem Center's neonatal care unit.Sample size was calculated with 95% confidence and power 80. 104 premature infants were treated with surfactant, 74 in survanta group and 30 in Curosurf group,. The differences between the two groups were assessed by ANOVA or the calculation of relative risks. <br/>Results: There were no statistically significant differences between infants treated with S and C in mean gestational age (30.58 vs. 29.00 weeks) and birth weight (1388 vs.1330 g).

It can progress to kernicterus in severe forms, unless an intervention is initiated. The objective of this study was to compare the efficacy of Clofibrate with Phenobarbital in full-term neonates with nonhemolytic jaundice. <br/>Methods: this double blind clinical trial study was performed on 60 neonate who were divided randomly in two groups of full-term jaundiced neonates: the clofibrate-treated group (n = 30) and the Phenobarbital group (n = 30). Infants in the clofibrate group received a single oral dose of 100 mg/kg clofibrate while the neonates in the Phenobarbital group received a single oral dose of 5 mg/kg Phenobarbital; both groups received phototherapy. Total serum and direct bilirubin levels were measured at the beginning, 12 and 24 hours after the initiation of treatment. <br/>Results: The mean ± SD total serum bilirubin level of the Phenobarbital group and clofibrate groups at enrollment was 17.84 ± 1.017 and 18.04 ±0.852 mg/dL, respectively. The mean ± SD total serum bilirubin in Phenobarbital group and clofibrate groups after 24 hours was 11.11 ± 1.273 and 12.55 ± 1.008 mg/dL, respectively (<em>P </em>= 0.000). After 72 hours of intervention, 25 (83%) neonates of the Phenobarbital group and 23 (76%) of the clofibrate group were discharged with a total serum bilirubin of P = 0.000). No side-effect was observed on serial examination during hospitalization, and on the first and seventh day after discharge. <br/>Conclusion: Phenobarbital in the compared with clofibrate results in a faster decline in total serum bilirubin, shorter duration of hospitalization and had no side effects in jaundiced full-term neonates.Mashhad University of Medical SciencesIranian Journal of Neonatology2251-75104320131001Effect of clofibrate on serum triglyceride and cholesterol after intravenous lipid in very low birth weight neonates2025174910.22038/ijn.2013.1749ENA MohammadzadehNeonatal Research Center, Imam Reza Hospital, Faculty of Medicine, Mashhad University of Medical Sciences, Mashad, Iran0000-0001-2345-6789AS FarhatNeonatal Research Center, Imam Reza Hospital, Faculty of Medicine, Mashhad University of Medical Sciences, Mashad, IranH EsmaeliBiostatistics PH.D.

Continuous positive airway pressure (CPAP) and Nasal Continuous positive airway pressure (NCPAP) are the methods of respiratory support especially for using in RDS of neonates. In other method surfactant is administered to babies via tracheal instillation. The aim of study was comparing nasal continuous positive airway pressure (NCPAP) with and without prophylactic surfactant therapy in preterm neonates’ RDS. <br/> Patients and methods: This is a randomized clinical trial study that performed on eighty newborns (28-34 weeks) who were born in Ali-Ebne-Abitaleb Hospital of Zahedan University of Medical Sciences from October 2008 to September 2010. Subjects were randomly classified in two groups whom received nasal CPAP alone or with surfactant (40 patients in each group).The Including criteria for entrance to research were approved suggested RDS, gestational age less than 34 weeks and neonates 72 hours after delivery . The data collected through direct observation and questionnaire contained fourteen items. Groups received either surfactant (Curosurf, Parma, Italy) with NCPAP or NCPAP alone. The data analyzed were conducted through SPSS 17.00 version and followed by Crosstab (Pearson Chi-square). <br/>Results: Results revealed that six neonates who received only NCPAP and four patients who received NCAPA plus surfactant required to MACHANICAL VENTILATION (MV) therapy. After a week, 33 neonates who received only NCPAP and 36 patients who received CPAP plus prophylactic surfactant remained alive. There was no significant difference between the groups regarding adverse outcomes (P=0.518). <br/>Conclusions: According to the results of this study, NCPAP is affordable as a safe protocol for RDS in preterm neonates. Further research especially with control or placebo groups is required to clarify and validate our findings.Mashhad University of Medical SciencesIranian Journal of Neonatology2251-75104320131001Could mean platelet volume predict developing of bronchopulmonary dysplasia in preterm infants with respiratory distress syndrome?3541175210.22038/ijn.2013.1752ENShamsollah NourripoorDepartment of Pediatrics, Amir-al-momenin Hospital, Semnan university of Medical Sciences , Semnan.

IranNooshin MasoudianDepartment of Neurology, Imam Reza Hospital, Tabriz University of Medical Sciences , Tabriz, IranJournal Article20131004Introduction: some studies have suggested correlation between MPV index and inflammatory diseases such as rheumatoid arthritis in adults. Though bronchopulmonary dysplasia is also an inflammatory disease which develops in preterm neonates with Respiratory distress syndrome, we decided to study the possible correlation between the mean platelet volume (MPV) and the occurrence of bronchopulmonary dysplasia (BPD) <br/>Subject & Methods: We reviewed the medical records of 280 infant with the diagnosis of RDS admitted to the neonatal intensive care unit of the Mahdieh obstetrics and gynecology Hospital of Tehran and Amir general Hospital of semnan from April 2008 to April 2012. Infants who have been expired before first month of life were excluded. Enrolled infants were divided into BPD and no-BPD groups (30 with and 250 without BPD). MPV was determined during first three days of life in all cases. <br/>Results: MPV measured during first three days of life was significantly( p=0.017) higher in the BPD than in the no-BPD group (10.8-0.96 versus 9.65-0.91 fL)but Platelet count at the same time were similar in the BPD and no-BPD groups, and MPV increment was associated with BPD development risk( (OR=1.6, 95%CI: 2.38-1.08, p=0.019) . <br/> Conclusion: We concluded that higher MPV in the first three days of life is a probable risk factor for the development of BPD in preterm infants with RDS. This might be attributed to the fact that high MPV could prone the neonate to inflammatory and oxidative lung damage.
