Positive effects of low intensity recorded maternal voice on physiologic reactions in premature infants.

OBJECTIVE: To evaluate the effect of low intensity recorded maternal voice on the physiologic reactions of healthy premature infants in the neonatal intensive care unit (NICU). METHODS: Physiologic responses of 20 healthy preterm infants in the NICU of Shariati Hospital, Tehran, were obtained during a 15min intervention including three 5min periods (no-sound control, audio recorded playback of mother's voice, no-sound post-voice). The intervention was presented three times a day for three consecutive days. During each intervention, oxygen saturation (%, OSPR), heart rate (HR), and respiratory rate (RR) were recorded at 1min intervals over the 15min and then averaged over each 5min period, resulting in 3 averages for each variable for each intervention. RESULTS: Repeated Measures Analysis of Variance were employed to examine each variable separately. Over the three days, comparison of oxygen saturation over each of the three periods (before, during voice, after) revealed an increase in oxygen saturation during the voice period, compared to the pre-voice period, which persisted over the post-voice period; there were no differences between the voice and post-voice periods. Analyses of the HR and RR data showed a decrease in both variables during the voice period compared to the pre-voice period which persisted over the post-voice period. Again, there were no differences between the voice and post-voice periods. CONCLUSION: Exposure to low intensity recorded maternal voice has positive effects on the preterm infants 'physiologic responses.

Is early breast milk fortification more effective in preterm infants?: a clinical trial.

OBJECTIVE: Breast feeding alone does not provide adequate nutrition for growth in preterm infants; therefore, fortifiers are added when over 70-80 cc/kg/day of breast milk is tolerated. As there are few studies comparing early and late breast milk fortification, the following study was conducted. STUDY DESIGN: This double-blind clinical trial was performed on 80 preterm infants (gestational age of 28-34 weeks, birth weight <2 kg). The newborns were randomly divided into two groups to receive either early or late fortification. The primary and secondary outcomes were the difference in growth indices and complications (including feeding intolerance, necrotizing enterocolitis (NEC), and septicemia) between the two groups, respectively. RESULTS: Both groups showed increases in growth indices; however, there was no statistically significant difference in increments of growth indices and complications between the two groups. CONCLUSION: Our findings suggest that early fortification from the first feeding in neonates with exclusive breast feeding did not improve growth in the first 4 weeks in preterm neonates in comparison with late fortification; so early fortification may not be cost effective.

External Otitis: An Unusual Presentation in Neonates.

Acute otitis externa (AOE) is an infection of the external auditory canal, the auricle, and the outer surface of the tympanic membrane. Although AOE is one of the most common otologic conditions encountered in pediatric population, it is known to primarily affect children older than 2 years. We report a case of AOE caused by Staphylococcus aureus in a 23-day-old neonate. A 23-day-old female infant presented to our neonatology clinic with irritability and discharge from the right ear. There were yellow otorrhea, mild erythema, and edema of right external ear canal. There was no sign of otitis media on otoscopy. The results of laboratory tests were insignificant. The discharge culture grew colonies of methicillin-sensitive Staphylococcus aureus. After 48 hours of treatment with intravenous cloxacillin, significant improvement was observed. The present case highlights an unusual presentation of staphylococcal infection in a neonate. This is the first case of methicillin-sensitive Staphylococcus aureus otitis externa in an immunocompetent newborn.

Severe neonatal hyperbilirubinemia leading to exchange transfusion.

BACKGROUND: Severe neonatal hyperbilirubinemia is associated with significant morbidity and mortality. This study was conducted to investigate the causes of severe hyperbilirubinemia leading to Exchange Transfusion (ET) from March 2009 to March 2011 in Bahrami children hospital, Tehran, Iran in order to establish guidelines to prevent profound jaundice & ET. METHODS: 94 neonates underwent ET for severe hyperbilirubinemia data for demographic data, and onset of jaundice, history of severe hyperbilirubinemia in siblings, blood group of both mother and neonate, G6PD activity, hemoglobin, hematocrite, reticulocyte count, peripheral blood smear, total and direct bilirubin before and after ET, direct and indirect Coombs, times of transfusion and the cause of hyperbilirubinemia were all recorded for analysis. RESULTS: Ninety four neonates (56.4% boys and 43.6% girls) underwent ET with a mean birth weight of 1950±40 g and a mean gestational age of 35.2±1.4 weeks. Premature labor, breastfeeding jaundice, ABO incompatibility and G6PDD with the frequency of 59(63%), 33(35%), 25(24/5%) and 12(12.8%) were of major causes of ET. CONCLUSIONS: Predisposing factors for severe hyperbilirubinemia in this study were premature labor, breastfeeding jaundice, ABO incompatibility and G6PDD. The authors recommend prevention of premature labor, reevaluation of successful breastfeeding education for mothers and screening infants for blood group and G6PD In the first of life. Arranging earlier and continuous visits in neonates with these risk factors during the first four days of life is also recommended.

Frequency and Susceptibility of Bacteria Caused Urinary Tract Infection in Neonates: Eight-Year Study at Neonatal Division of Bahrami Children's Hospital, Tehran Iran.

BACKGROUND: Susceptibility pattern of organisms causing urinary tract infection (UTI) in neonate would potentially improve the clinical management by enabling clinicians to choose most reasonable first line empirical antibiotics. This study aimed to this end by studying isolated organisms from neonates with UTI in an inpatient setting. METHODS: Current retrospective study has recruited all cases of neonatal UTI diagnosed through a suprapubic/catheterized sample, admitted to Neonatal Division of Bahrami Children's Hospital, Tehran, Iran, from June 2004 to June 2012. RESULTS: Escherichia coli was the dominant (64.4%) bacteria among a total of 73 cases (69.9% boys and 30.1% girls; aged 14.14 ± 7.68 days; birth weight of 3055.85 ± 623.00 g) and Enterobacter (19.2%), Klebsiella (12.3%), and Staphylococcus epidermdisis (4.1%) were less frequent isolated bacteria. E. coli was mostly resistant to ampicillin (93.6%), cefixime (85.7%) and cephalexin (77.3%), and sensitive to cefotaxime (63.6%). Enterobacter found to be most resistant to amikacin (100%), ampicillin (92.85%), and most sensitive to ceftizoxime (71.4%). CONCLUSION: A high ratio (> 92.85%) of resistance toward ampicillin was observed among common neonatal UTI bacterial agents. Having this finding along with previous reports of emerging resistance of neonatal uropathogensto ampicillin could be a notion that a combination of a third generation cephalosporin and an aminoglycoside would be a more reasonable first choice than ampicillin plus an aminoglycoside.

Neonatal urinary tract infection: clinical response to empirical therapy versus in vitro susceptibility at Bahrami Children's Hospital- Neonatal Ward: 2001-2010.

Urinary tract infection (UTI) is a neonatal life threatening infection which is usually treated with ampicillin plus an aminoglycoside or a third-generation cephalosporin. Recently, growing number of Escherchia coli species resistant to ampicillin and aminoglycosides have raised concerns regarding the necessity to change the empirical therapy. This motivates us to determine neonatal UTI clinical response to the used empirical antibiotics. This study was designed as a Case Series. All neonates admitted to Bahrami Children Hospital, Tehran, Iran, during 2001- 2010 with a diagnosis of UTI surveyed by simple non-random sampling. Totally, 97 cases (including 83 (85.6%) term, 8 (8.2%) post-term and 6 (6.2%) preterm neonates) with a mean age of 15.85 ± 7.05 days at admission ,average weight of 3195.57 ± 553g at birth and 3276.29 ± 599.182 g at admission were studied. Ampicillin resistance in 93 cases (95.9%), gentamicin resistance in 51 cases (52.6%) and trimethoprim- sulfamethoxazole resistance in 44 cases (45.4%) were the leading resistances in this study. Escherichia coli was the dominant organism in 76.3% (74 patients) of study population which was resistant to ampicillin in 95.9% (71 cases). Despite the observed resistant to initial empirical regimen antibiotics (especially ampicillin), 81.4% of patients responded to empirical therapy. However, we believe till conductance of more detailed studies regarding the relationship between empirical therapy and antibiogram concordance, physicians take ampicillin-resistant E coli infection issue into accounts from the first steps of management of critically ill neonates.
