Objective: To assess the ability of TREC and KREC counts to identify patients with combined T and B cell immunodeficiency in a pilot study in Israel.

Methods: We studied seven children born in Israel during the years 2010–2011 and later diagnosed with SCID, and an additional patient with pure B cell immunodeficiency. TREC and KREC in peripheral blood upon diagnosis and in their neonatal Guthrie cards were analyzed using real-time quantitative polymerase chain reaction, as were Guthrie cards with dried blood spots from healthy newborns and from normal and SCID-like controls.

Results: The first features suggestive of SCID presented at age 3.1 ± 2.4 months in all patients. Yet, the diagnosis was made 4.1 ± 2.9 months later. Their TREC were undetectable or significantly low at their clinical diagnosis and in their originally stored Guthrie cards, irrespective of the amount of their circulating T cells. KREC were undetectable in six SCID patients who displayed B cell lymphopenia in addition to T cell lymphopenia. KREC were also undetectable in one patient with pure B cell immunodeficiency.

Conclusions: TREC and KREC quantification are useful screening tests for severe T and B cell immunodeficiency. Implementation of these tests is highly important especially in countries such as Israel where a high frequency of consanguinity is known to exist. 

Background: Music therapy has been recommended as an adjuvant therapy for both preterm infants and mothers during their stay in the neonatal intensive care unit (NICU), and has been shown to have beneficial effects.

Objectives: To study the usefulness of combining live harp music therapy and kangaroo care (KC) on short-term physiological and behavioral parameters of preterm infants and their mothers in the NICU setting.

Methods: Included in this study were stable infants born between 32 and 37 weeks of gestation, with normal hearing .Mother-infant dyads were randomly assigned to KC and live harp music therapy or to KC alone. Using repeated measures, neonatal and maternal heart rate, oxygen saturation and respiratory rate were recorded along with neonatal behavioral state and maternal anxiety state. Maternal age, ethnicity, education, and love of music were documented.

Results: Fifty-two mother-infant dyads were tested. Compared with KC alone, KC and live harp music therapy had a significantly beneficial effect on maternal anxiety score (46.8 ± 10 vs. 27.7 ± 7.1, respectively, P < 0.01). Infants’ physiological responses and behavior did not differ significantly. No correlation was found between mothers’ age, ethnicity, years of education and affinity for music, and anxiety scores (P = 0.2 to 0.5 for all four variables).

Conclusions: KC combined with live harp music therapy is more beneficial in reducing maternal anxiety than KC alone. This combined therapy had no apparent effect on the tested infants’ physiological responses or behavioral state.
 

Background: Fractures of the humerus in neonates can pose a diagnostic challenge, especially when the fracture occurs in the proximal or distal epiphysis.

Objectives: To review our experience in the diagnosis and treatment of birth-related humeral fractures.

Methods: Between the years 2001 and 2009, seven newborn patients and two patients treated in the neonatal intensive care unit sustained a fracture of the humerus. Four of the fractures occurred in the humeral shaft, three in the proximal epiphysis and two in the distal epiphysis. In all the newborn patients the diagnosis was made on the first day of life using radiography and ultrasonography. The fractures of the shaft and of the distal epiphysis were treated by gentle manipulation and casting, and the fractures of the proximal epiphysis were treated by swaddling.

Results: All of the patients demonstrated fracture union within 2 weeks, and radiographs at the age of 6 months demonstrated complete remodeling of the fracture.

Conclusions: Ultrasonography is a simple, readily available and inexpensive modality for the diagnosis of birth-related fractures of the humerus, especially in the yet unossified epiphyses.

Background: Hyperbilirubinemia of the newborn is common. Rarely is an underlying disease other than physiologic hyperbilirubinemia considered the cause of high bilirubin levels. Some of the laboratory tests recommended by the American Academy of Pediatrics are expensive and do not always lead to diagnosis.

Objective: To evaluate the efficacy of standard laboratory tests performed on newborn infants requiring phototherapy for hyperbilirubinaemia.

Methods: We conducted a retrospective chart review that included neonates born during a 6 month period with birth weight > 2500 g treated with phototherapy for hyperbilirubinemia (n=282) according to published guidelines. The main outcome measures were primary and maximal bilirubin values (mg/dl), time to jaundice (in days), the number of bilirubin tests undertaken and whether the patient showed abnormal functioning, and the number of days in follow-up.

Results: Thirty-three neonates (11.7%) were positive in at least one laboratory test (defined as "Abnormal" in our study), 45.5% of whom met the criteria for phototherapy during the first 48 hours of life. Among the newborns who were negative for all laboratory tests (defined as "Normal"), only 6.8% met phototherapy criteria within their first 48 hours of life (P < 0.001). In the Normal group there was a consistent decrease in total serum bilirubin values shortly after phototherapy was begun, while the Abnormal group presented an increase in serum bilirubin values during the first 12 hours of phototherapy. None of the infants had conjugated (direct) hyperbilirubinemia during the study period.

Conclusions: Most neonates presenting with a laboratory identifiable etiology for hyperbilirubinemia (i.e., hemolysis) can be distinguished from those who test negative, mainly based on the timing of presentation and response to phototherapy. A more meticulous selection of patients and reduction in the magnitude of routine laboratory testing can safely reduce discomfort to infants with hyperbilirubinemia as well as costs.

Background: Early-onset neonatal sepsis is a major cause of morbidity and mortality among newborn infants.

Objectives: To determine the incidence, type of pathogens and resistance to antibiotics among newborns with early-onset neonatal sepsis, and to identify the risk factors predisposing infants to resistant pathogens in order to reevaluate antibiotic regimens appropriate for resistant bacteria in these high risk neonates.

Methods: We retrospectively studied maternal and neonatal variables of 73 term and near-term infants and 30 preterm infants, born over a period of 10.5 years and exhibiting early-onset neonatal sepsis (positive blood cultures in the first 72 hours of life).

Results: Predominant pathogens in term and near-term infants were gram-positive compared with gram-negative organisms (mostly Escherichia coli) in preterm infants. Mothers of infants with antibiotic-resistant organisms were more likely to have prolonged rupture of membranes and prolonged hospitalization before delivery and to be treated with antibiotics. No trends towards more resistant strains of pathogens were recorded over the 10.5 years of the study period.

Conclusions: Early-onset neonatal sepsis in term infants differs in bacterial species from that in preterm infants, with predominantly gram-positive organisms in term and near-term infants and gram-negative organisms in preterms. Rates of bacterial resistance to the combination of ampicillin and gentamicin, though higher among infants born to mothers with prolonged hospitalization who had been treated with antibiotics, still remained very low in our department. Thus, it seems that our classic antibiotic regimen is still appropriate for both term and preterm newborns.
 

Background: Over the last two decades, the epidemiology, treatment strategy and mortality rate for congenital diaphragmatic hernia have changed.

Objectives: To retrospectively analyze our experience with CDH[1] of the last 22 years.

Methods: We reviewed the charts of all infants suffering from CDH between 1985 and 2007. Prenatal and maternal as well as perinatal and neonatal data were collected, including outcome parameters. The 71 infants that we identified were divided them into two historical groups: from 1985 to 1995 (group 1, 123 patients) and from 1996 to 2007 (group 2, 45 patients).

Results: We found an increase in the incidence of prenatal diagnosis and a subsequent significant decrease in gestational age at diagnosis in group 2 (25 weeks gestation, compared with 30 weeks gestation in group 1, P = 0.018). In addition, we noted a trend toward a reduced number of infants with right-sided hernia and associated cardiac anomalies. The timing to post-delivery surgery was significantly longer in group 2 (20 hours in group 1 vs. 53 hours in group 2, P < 0.001). A significant reduction in postoperative mortality was demonstrated in group 2 compared with group 1 (13.5% vs. 38.7% respectively, P = 0.04),

Conclusion: Our data suggest a higher survival rate for operated infants in group 1 during the last decade, probably due to changes in preoperative methods of treatment as well as later surgery timing compared to group 1. We speculate that today’s cases of congenital diaphragmatic hernia are probably milder than in the past due to earlier and more detailed prenatal diagnosis and subsequent termination of pregnancies for the more severe forms of the disorder. 

Background: Intrapartum risk is based mainly on obstetric history, which is lacking in primiparous women.

Objectives: To ascertain whether the traditional known risk of primiparity is an independent variable for both maternal and neonatal outcome.

Methods: All women admitted to labor during March-April 2002 were canvassed for eligibility for participation in the study based on an obstetric risk scoring system developed and validated for our population. During the study period, 1473 women presented for delivery. Of these, 298 women (20%) were eligible according to the exclusion criteria as "low risk" parturients: 135 (45%) were primiparous and 163 (55%) were multiparous (2–5 births).

Results: After correction for significant confounding factors, primiparity was revealed as an independent significant risk factor for instrumental delivery (odds ratio 15.5, 95%confidence interval 1.88–125) and for early postpartum hemorrhage (OR[1] 5.6, 95%CI[2] 1.9–16.6).

Conclusions: This study highlights early postpartum hemorrhage as a significant risk for primiparous women, independent of mode of delivery, and also confirms previous reports of maternal complications requiring transfer from birth centers/home deliveries to tertiary centers.

Background: A substantial number of premature deliveries occur in hospitals lacking neonatal intensive care facilities. We previously demonstrated a comparable outcome of very low birth weight infants delivered in a level II nursery to that of inborn infants delivered in our tertiary care center, but a similar comparison of extremely low birth weight infants has not been done.

Objectives: To compare the neonatal outcome (mortality, severe intraventricular hemorrhage/periventricular leukomalacia, bronchopulmonary dysplasia and intact survival) of inborn and outborn ELBW[1] infants, accounting for sociodemographic, obstetric and perinatal variables.

Methods: We compared 97 ELBW infants (birth weight ≤ 1000 g.) delivered between the years 2000 and 2004 in a hospital providing neonatal intensive care to 53 ELBW babies delivered in a referring hospital. A univariate model was first applied to examine the associations of the individual independent variables with the outcome variable, followed by a logistic stepwise regression analysis for each of the outcome variables. The odds ratios for each predictor were reported as well as their P values and 95% confidence intervals.

Results: In the stepwise logistic regression analysis, accounting for a possible confounding effect of the independent variables, ‘hospital of birth’ remained a statistically significant predictor in the final step only for mortality, with odds ratio (inborns relative to outborns) of 3.32 (95%CI[2] 1.19–9.28, P = 0.022). No statistically significant associations with the other outcome variables were found (severe IVH[3]/PVL[4] odds ratio = 1.99, 95%CI = 0.77–5.14, P = 0.155; BPD[5] odds ratio = 0.60, 95%CI = 0.19–1.91, P = 0.384; intact survival OR[6] = 0.56, 95%CI = 0.23–1.35, P = 0.195).

Neonatal lupus erythematosus is an uncommon transplacentally Acquired Autoimmune Disorder. The most common clinical manifestations are skin rash, congenital atrioventricular block, thrombocytopenia, leucopenia, anemia, and hepatosplenomegaly. Usually, the skin rash resembles subacute cutaneous lupus, but different forms of rash have been reported in Neonatal lupus erythematosus and some are rare forms. NLE should be suspected in babies with atypical skin lesions, even if present at birth.
