Background: Respiratory distress syndrome (RDS) or hyaline membrane disease (HMD) is the most common cause of neonatal morbidity and mortality in preterm infants. We aimed to determine the frequency of RDS among 3 groups of preterm infants and the value of some related factors. Methods: A cross-sectional, descriptive analytical investigation was carried out in the NICU ward of Akbarabadi Hospital (Tehran-Iran) during spring 2011. Newborns' data were collected and assessed by using their hospital medical records. Seventy-three preterm infants with gestational age < 34 weeks were hospitalized in the NICU. All participants were divided into 3 groups: extremely preterm (<28 weeks), very preterm (28 to <32 weeks) and moderate preterm (32 to 34 weeks). Frequency of RDS and some related factors were compared among 3 groups. Results: RDS was observed in 65.6% of all participants; however frequency of RDS was not different between three groups. An inversely correlation was found between gestational age and mortality rate (p = 0.05). In regard to Betamethasone administration prior to birth, this interval was significantly longer in alive neonates in comparison to infants who died (p < 0.05). Conclusion: RDS was frequent in preterm neonates with gestational age < 32 weeks. Time of Betamethasone administration prior to birth can significantly influence on neonatal mortality rate.
Asphyxia is a common cause of mortality and morbidity among neonates. Following severe asphyxia and ischemia, reperfusion occurs which damages vital organs like the kidneys. This study was conducted to determine the prevalence of AKI based on the definition of a serum creatinine level higher than 1.5 mg/dL, in neonates with asphyxia. Materials and Methods: This retrospective study was performed in Ali-Asghar and Shahid-Akbar-Abadi Hospitals, Tehran, Iran in a period of one year. The medical documents of all newborns diagnosed with asphyxia were studied. The asphyxia grade was determined according to the asphyxia Sarnat criteria. The kidney function was evaluated based on the serum creatinine level. Results: Thirty-eight cases met the inclusion criteria. There were 13 Sarnat grade-1 cases (34.2%), 19 grade 2 cases (50%), and 6 grade 3 patients (17.6%). Three (7.8%) patients (2 patients in grade 3 and one patient in grade 2 of the Sarnat grading scale) developed AKI. AKI was detected in 33% of the patients in grade 3 and 5.2% of the patients in grade 2 of the Sarnat grading scale. Nine patients (23%) died, of whom 83% were in grade 3 and 16.9% in grade 2 of asphyxia. Conclusions: AKI developed in 7.8% of the cases, of whom 33% were in grade 3 and 5.2% were in grade 2 of the Sarnat grading scale. The low rate of AKI development in our study might be duo to the small sample size and patient mortality in the first 3 days of life.
Background: Asphyxia is one the most important causes of neonatal mortality and morbidity. It is suggested that magnesium may have a protective role against cellular damage during hypoxic brain insult, or change effect post-asphyxia consequences. Our study was performed for comparison of serum magnesium in neonates with and without asphyxia. Methods: This study was done in Neonatal Ward of Ali-Asghar hospital, from January 2010 to 2011 in Tehran, Iran. Serum magnesium levels of seventy-six cases with a diagnosis of asphyxia grade 2 were compared with 76 normal newborns. Collected data including gestational age, sex, birth weight and serum magnesium levels were analyzed by SPSS software. Results: Of 152 neonates, 81 (53.3%) were male. Mean gestational age was 37.9 ± 1.07 weeks. Mean birth weights were 3172.9± 411.20 grams. Mean serum magnesium levels were compared in asphyxiated and normal neonates and between two groups significant difference was found (p=0.01). The odds ratio was 2.188 (with lower1.826, upper 2.626 and confidence interval 95 percent) which suggested a significant correlation between asphyxia and hypomagnesemia. Conclusion: This study showed that serum magnesium levels in neonates with asphyxia was significantly lower than normal neonates and asphyxia can lead to hypomagnesemia.
Introduction. Vitamin D status is a key determinant of bone health and growth during childhood and adolescence. Therefore, we design a study to find out the association between the levels of serum vitamin D and need to consumption of vitamin D supplement.Method and materials. In this cross sectional study infants under 20 months referred to Ali Asghar Children's Hospital were included. Infants with maternal diseases and congenital malformations were excluded. All infants used vitamin D3 supplementation 400 IU per day from day fifth of birth. The level of 25-hydroxy vitamin D at the age of 1 years (month 12) were measured. Level of 25-hydroxy vitamin D in mothers were checked, too. Furthermore, we defined sufficient level of 25-hydroxy vitamin D ≥30ng/ml.Results. In this study, 68 infants under 20 months were examined. Half of them were boy. Mean age of infants was 16±3 months and mothers was 33±3 years old. In addition, the mean level of serum 25-hydroxy vitamin D in the infants were 40.99±13.86 ng/ml and in mothers were 31.39±13.14 ng/ml. 62.1% of mothers were in sufficient group and also 83% of infants had sufficient vitamin D level (25-hydroxy vitamin D ≥ 30ng/ml). There was not any significant correlation between vitamin D level in infants and mothers (P value=0.965). The mean level of serum vitamin D3 in boys was 39.55±3.79 ng/ml (12-51) and girls was 35.32±3.67 ng/ml (13.4-50). Similarly, significant relationship was not shown between gender and vitamin D of infants (P value = 0.437). Level of vitamin D in second children was significantly higher than first children (P value=0.011). The correlation between gestational age and vitamin D3 deficiency was also insignificant (P value=0.087). Head circumference (r= -0.404, P value=0.014) and age of mothers (r= 0.344, P value=0.04) correlated with vitamin D.Conclusion. In summary, we demonstrated most of the infants had sufficient vitamin D level at the age of 1 year. So it is recommended to continue vitamin D3 supplementation consumption.
