ABSTRACT
Background and Aims: Preterm infants are more prone to poor growth and neurodevelopment. The first few weeks of life play an important role in the growth and neurodevelopment of very-low-birth-weight (VLBW) infants. The Vermont Oxford Network, evaluating the postnatal growth of preterm newborns, considers growth failure as body weight <10th percentile for postmenstrual age. This study aims to assess the frequency of postnatal growth failure in VLBW infants in Southwest Iran. Methods: This descriptive analytical study was performed on VLBW infants in the neonatal intensive care unit (NICU) of Imam Khomeini Hospital (Ahvaz, Iran) from September 2019 to August 2020. Growth failure was confirmed when a newborn's weight at discharge was smaller than the 10th percentile corrected age (≤-1.28 Z-score), based on the Fenton growth chart as a standard. This study was performed on 353 infants. Intrauterine growth retardation was detected in 29% of female and 10.6% of male newborns, who were born at a gestational age of 32 and 31 weeks or higher respectively. Upon hospital discharge, postnatal growth failure was detected in all newborn girls, except for those born at 32 weeks of gestation, and all newborn boys, except for those born at a gestational age of 33-34 weeks. Conclusion: Postnatal growth retardation in VLBW infants born in our NICU was much higher than that of other centers. Overcrowding, short length of hospitalization, low nurse-to-patient ratio, and untrained nurses were among the reasons for poor postnatal growth in our center.
ABSTRACT
BACKGROUND: The most common cause of respiratory failure in premature infants is respiratory distress syndrome. Historically, respiratory distress syndrome has been treated by intratracheal surfactant injection followed by mechanical ventilation. In view of the risk of pulmonary injury associated with mechanical ventilation and subsequent chronic pulmonary lung disease, less invasive treatment modalities have been suggested to reduce pulmonary complications. METHODS: 148 neonates (with gestational age of 28 to 34 weeks) with respiratory distress syndrome admitted to Imam Khomeini Hospital in Ahwaz in 2018 were enrolled in this clinical trial study. 74 neonates were assigned to duo positive airway pressure (NDUOPAP) group and 74 neonates to nasal continuous positive airway pressure (NCPAP) group. The primary outcome in this study was failure of N-DUOPAP and NCPAP treatments within the first 72 h after birth and secondary outcomes included treatment complications. RESULTS: there was not significant difference between DUOPAP (4.1 %) and NCPAP (8.1 %) in treatment failure at the first 72 h of birth (p = 0.494), but non-invasive ventilation time was less in the DUOPAP group (p = 0.004). There were not significant differences in the frequency of patent ductus arteriosus (PDA), pneumothorax, intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia (BPD), apnea and mortality between the two groups. Need for repeated doses of surfactant (p = 0.042) in the NDUOPAP group was significantly lower than that of the NCPAP group. The duration of oxygen therapy in the NDUOPAP group was significantly lower than that of the NCPAP group (p = 0.034). Also, the duration of hospitalization in the NDUOPAP group was shorter than that of the NCPAP group (p = 0.002). CONCLUSIONS: In the present study, DUOPAP compared to NCPAP did not reduce the need for mechanical ventilation during the first 72 h of birth, but the duration of non-invasive ventilation and oxygen demand, the need for multiple doses of surfactant and length of stay in the DUOPAP group were less than those in the CPAP group.

Background: Respiratory distress syndrome (RDS) is one of the main causes of mortality in premature neonates. Treatment of these neonates with invasive mechanical ventilation has side effects such as chronic pulmonary diseases. Noninvasive ventilation, such as nasal continuous positive airway pressure (NCPAP) and nasal high-frequency oscillation ventilation (NHFOV), has shown to reduce the burden of chronic lung disease. NHFOV is a promising new mode of noninvasive ventilation and may reduce the need for mechanical ventilation and reduce possible complications. In this study, we hypothesized that early NHFOV would reduce the need for invasive respiratory support in comparison to NCPAP in preterm neonates with RDS.Methods: One hundred twenty-four neonates between 28 to 34 weeks of gestational age (GA) with RDS hospitalized at Imam Khomeini Hospital, Ahvaz in 2016 were included in this randomized controlled study. The primary outcomes were the failure of NHFOV and NCPAP within 72 h after birth. The secondary outcomes were the duration of invasive ventilation and possible side effects.Results: Out of 124 neonates in this study, 63 and 61 neonates were studied in the NHFOV and NCPAP groups, respectively. There were no significant differences between NHFOV (6.5%) and NCPAP (14.1%) groups in terms of rates of primary consequences (p = .13). However, the duration of noninvasive ventilation in NHFOV was significantly less than that of NCPAP group (p = .01).Conclusion: In our study group, preterm infants from 28 to 34 weeks of GA, NHFOV did not reduce the need for mechanical ventilation during the first 72 h after birth compared to NCPAP; however, the duration of noninvasive ventilation in the NHFOV group was significantly shorter.

BACKGROUND: Transient tachypnea of the newborn (TTN) is a self-limiting disease that results from a reduction in the rate of lung fluid clearance in neonates. A delay in lung fluid absorption in neonates disrupts the transition from intrauterine to extrauterine life. Use of beta-adrenergic antagonists, such as salbutamol, accelerates lung fluid clearance. The current study aimed to evaluate the effect of inhaled salbutamol on the clinical progression of TTN treatment. METHODS: In the current triple-blind clinical trial, a total of 148 inpatients diagnosed with TTN were randomly divided into 2 groups. The treatment group (n = 74) received inhaled salbutamol and the placebo group (n = 74) received inhaled normal saline. The drug administration was started 6 h after birth and continued in the case of continued respiratory distress and the need for oxygen as adjuvant therapy for up to 72 h maximum after the initiation of treatment. To evaluate the response to treatment with inhaled salbutamol, we assessed the respiratory rate (RR), heart rate (HR), fraction of inspired oxygen (FIO2) level, and O2 saturation at intervals of 30 min as well as 1 h and 4 h after drug administration. The results were compared between the groups. RESULTS: The results of the current study indicated a significant difference between the treatment and placebo groups in the treatment duration, hospitalization duration, need for continuous positive airway pressure therapy (CPAP), and time of oral feeding initiation. In addition, no complication was observed during the treatment. It is noteworthy that, following the improvement of disease symptoms and reduction of hospitalization. This reduction may decrease the treatment costs and anxiety of parents, which was associated with proper mental and economic outcomes. CONCLUSION: Although, in the current study, drug administration was continued for 72 h maximum, the prescription of at most 4 doses of salbutamol may have had maximum efficiency in the remediation process. To evaluate the therapeutic role of inhaled salbutamol, further studies are recommended.

BACKGROUND: The muscle-sparing thoracotomy (MST) has not yet been thoroughly studied and assessed in comparison to the traditional thoracotomy method in newborns. AIM: To compare the outcomes of MST and standard posterolateral thoracotomy (PLT) in newborns. METHODS: Randomized, controlled, double-blind trial on 40 neonates with esophageal atresia, comparing the time of beginning a surgery until seeing the pleura, the duration of hospitalization in the neonatal intensive care unit, the time in ventilator, the time of returning the shoulder function, the time of returning the Moro reflex, and the mortality between the two techniques. RESULTS: The data showed no differences between the two groups in basic information (weight, height, gender, numbers of prematurity neonates and caesarean). The results on the size of the scar in the MST group was significantly lower than in the PLT group. Also, the time of returning the shoulder function in MST group was earlier than in PLT group. There were no significant differences in the duration since the beginning the surgery to see the pleura, the time of being hospitalized in intensive unit, the time that the infant required ventilator, returning time of the Moro reflex in 1st and 3rd months after the operation, and the mortality rates between MST and PLT groups. CONCLUSION: It seems that the advantages of using MST over PLT procedure in neonates include the earlier shoulder function recovery and also superior cosmetic results.

INTRODUCTION: The pathogenesis of congenital diaphragmatic hernia (CDH) is not clear. Risk factors including environmental factors have been implicated in the pathogenesis of few congenital anomalies. We aimed to assess the effect of season on the incidence of CDH and mortality rate in the southwest of Iran. MATERIAL AND METHODS: In this retrospective study, the records of 60 patients with CDH who were admitted at Neonatal Intensive Care Unit (NICU) of Imam Khomeini Hospital of Ahvaz, Iran were evaluated. RESULTS: Assuming that all the neonates born with CDH in the region reach this hospital, overall CDH prevalence rate was 1.09 per 10 000 total births. Conceptions in spring and summer in this region had statistically significantly higher incidence of CDH. Survival rate in the series was 41.6%. CONCLUSION: Seasonal variation has impact on the incidence of CDH. Mortality rate in neonates with CDH is still very high.
ABSTRACT
OBJECTIVES: The objectives were to evaluate the relation between fetal anthropometric parameters and cord blood concentration of adiponectin and high sensitivity C-reactive protein (hs-CRP). Subjects and methods: A total of 104 pregnant women (52 with gestational diabetes mellitus [GDM], 52 with normal glucose tolerance (NGT) participated. Venous cord blood samples were obtained at delivery, centrifuged and the plasma was stored at -20°C. The samples were assessed for adiponectin and hs-CRP using the ELISA method. Statistical analysis was done using SPSS software. RESULTS: The adiponectin concentration was higher in the GDM group than in the NGT group (11.05 ± 4.1 µg/mL in GDM vs. 5.34 ± 2.63 µg/mL in NGT, p < 0.001). GDM was also higher in neonates delivered at later gestational ages (p < 0.001, Pearson correlation = 0.59). There was a positive correlation between cord blood adiponectin and birth weight in the GDM group (p < 0.001, Pearson correlation = 0.619) but not in the NGT group. There was no significant correlation between adiponectin and infant length or head circumference. There was also no significant difference in cord blood hs-CRP concentration between groups. No relation was found between hs-CRP and newborn anthropometric parameters. CONCLUSION: In the GDM group, adiponectin concentration was considerably higher and had a positive correlation with the ponderal index and birth weight which was not found in the NGT group.

BACKGROUND: This study aimed to evaluate the radiation dose received by premature neonates using diagnostic radiographies. METHODS: This cross-sectional study was conducted on 116 premature neonates with gestational age from 25 to 37 weeks; with the diagnosis of neonatal respiratory distress syndrome (NRDS) and tachypnea, they were admitted to a neonatal intensive care unit (NICU) at Ahvaz Imam Khomeini Hospital in 2015. For assessing the dose received, the model GR-200 thermoluminescent dosimeter (TLD) was used. For each premature neonate under radiation, three TLDs separately (one for each) were placed on surfaces of Ch1, T1, and G1 (chest, thyroid, and gonad of first newborn, respectively). Moreover, for the adjacent neonate at a distance of 60 - 100 cm, two TLDs were laid in the surfaces of T2 and G2 (thyroid and gonad of second newborn, respectively). The dose received by TLDs for any baby and the adjacent neonate under the entrance surface dose (ESD) was estimated. RESULTS: The mean of neonates' weight under study was 1,950.78 ± 484.9 g. During the hospitalization period, minimum one and maximum three radiographies were done for any premature neonate. The doses received in the premature neonates to Ch1, T1 and G1 were 0.08 ± 0.01, 0.06 ± 0.01, and 0.05 ± 0.01 mSv, respectively and for adjacent infants for T2 and G2 were 0.003 ± 0.001 and 0.002 ± 0.0009 mSv, respectively. CONCLUSIONS: In the study, radiation dose received by organs at risk of premature neonates was lower than the international criteria and standards, therefore, also due to the lack of radiation damage threshold, to limit collimator, and the use of the proper filtration, kilovoltage and time during radiography of premature neonates are recommended.
ABSTRACT
Adams-Oliver syndrome (AOS) is characterized by the combination of congenital scalp defects (aplasia cutis congenita) and terminal transverse limb defects of variable severity. It is believed that Adams-Oliver syndrome without major organ abnormalities does not necessarily alter the normal lifespan. We present a case without detectable major organ abnormality contrary to life but with poor weight gain. A male infant with scalp and skin cutis aplasia, generalized cutis aplasia, dilated veins over scalp and trunk, hypoplastic toes and nails of feet, glaucoma, poor feeding and poor weight gain. This report shows a case of AOS without major multiple organ abnormalities but with poor feeding and abnormal weight gain that may be alter the normal lifespan.
ABSTRACT
BACKGROUND: In addition to surfactant deficiency, increase of lung fluid content and secretion of fluid derived from the blood participate in the pathogenesis of RDS in newborns. We hypothesized that the administration of salbutamol (ß-agonist) to increase lung fluid absorption would decrease the INSURE failure rate in newborns with respiratory distress syndrome (RDS) treated with intratracheal surfactant. METHODS: Design Blinded, randomized clinical trial study. Setting/population Level III NICU, premature infants with RDS requiring intratracheal Surfactant. Forty Eight newborns with RDS treated with intratracheal Surfactant were randomized into two groups as Group A, Normal saline (as control group) and Group B (intervention group), Salbutamol were administered intratracheally in addition to Surfactant. Intubation-Surfactant administration- Rapid Extubation (INSURE) failure rate as primary outcome and secondary outcome as follow: duration of the need to NCPAP, mechanical ventilation and oxygen therapy; complications (patent ductus arteriosus, pneumothorax); mortality (respiratory or prematurity related complication) and the duration of hospitalization were assessed. RESULTS: Twenty Four patients in each group were studied. INSURE failure was seen in16 (66.7 %) and 10 (41.7 %) of normal saline and salbutamol groups respectively (p = 0.082). The duration of NCPAP in control group was 69.5 ± 54.9 h while in Salbutamol group was 51.6 ± 48.7 h (p = 0.316). All of deaths were related to respiratory failure. No differences in mortality or complications of RDS were observed. The duration of hospitalization was longer in control group than interventional group, 28.3 ± 18.1 and 18.6 ± 8.6 days, respectively. (p = 0.047). CONCLUSION: Salbutamol may improve the clinical course of newborns with RDS requiring Surfactant. TRIAL REGISTRATION NUMBER: IRCT2014072714215N1.

OBJECTIVE: The incidence of Transient Tachypnea of Newborn (TTN) is higher in infants born by cesarean section than with vaginal delivery. Treatment of transient tachypnea of newborn is supportive. The purpose of this study was to assess the effect of restricted fluid volume intake on the course of respiratory distress in patients with TTN. METHODS: This is a quasi-experimental clinical trial of 83 neonates diagnosed with TTN admitted to a neonatal intensive care unit in south west Iran. In this study the effect of restriction of maintenance fluid volume in the course of respiratory distress in newborns with transient tachypnea was assessed. FINDINGS: In the standard fluid volume intake group 18 (42.8%) cases needed nasal continuous positive airway pressure (NCPAP) and one (2.38%) case mechanical ventilation, and in restricted fluid volume intake group 13 (32.5%) cases needed NCPAP and two (5%) cases mechanical ventilation. 54.82% of cases were supported with oxyhood in the standard fluid volume and 62.5% in the restricted fluid volume intake group. Differences in duration of the needed NCPAP and oxygen hood between the two groups were significant. Fluid restriction had no adverse effect on the urine specific gravity or weight loss of the studied newborns. CONCLUSION: Limited fluid administered to newborns with transient tachypnea of newborn is safe and resulted in shorter duration of respiratory support.
ABSTRACT
BACKGROUND/AIM: This study was conducted to provide sonographic measurements of the abdominal esophagus length in neonates and infants with and without gastroesophageal reflux disease (GERD) and to investigate its diagnostic value. GERD severity was also evaluated and correlated with esophageal length. It is a prospective case-control study. MATERIALS AND METHODS: This prospective case-control study comprised 235 neonates and infants (120 without reflux and 115 with reflux). There were 40 children without reflux in each of three age categories: less than 1 month, 1-6 months, and 6-12 months. Of the children with reflux, 40 were less than 1 month old; 37, 1-6 months; and 38, 6-12 months. The abdominal esophagus was measured from its entrance into the diaphragm to the base of gastric folds in fed infants. GERD was sonographically diagnosed and confirmed by a barium meal. The number of refluxes during a 10-min period were recorded. RESULTS: Neonates and infants with reflux had a significantly shorter abdominal esophagus than subjects without reflux: the mean difference in neonates, 4.65 mm; 1-6 months, 4.57 mm; 6-12 months, 3.61 mm. CONCLUSIONS: Children with severe reflux had a shorter esophagus compared with those with mild and moderate reflux only in the neonate group. Therefore, thinking of GERD and carefully looking for its symptoms is necessary to avoid unnecessary utilization of healthcare resources in children with severe reflux.
