Severe leukemoid reaction in a preterm infant with congenital cytomegalovirus infection.

Leukemoid reaction, defined as a total leukocyte count of >50,000/mm, is most commonly related to antenatal administration of steroids, infections, and transient myeloproliferative disorder of Down syndrome in newborns. Atypical presentations of viral infections can be a diagnostic challenge in the newborn period. Cytomegalovirus (CMV) infection causes a multisystem disease, and symptomatic infants generally present with intrauterine growth restriction, hepatosplenomegaly, cholestasis, rash, thrombocytopenia, and microcephaly. We present a case of a preterm infant with severe myeloid leukemoid reaction (leukocyte count >100,000/mm) at birth who was diagnosed with congenital CMV infection on the basis of CMV polymerase chain reaction results after the appearance of cholestasis, blueberry muffin rash, and hepatosplenomegaly.

Congenital megalourethra presenting with large cystic mass in the inguinal area.

Congenital megalourethra is a rare urogenital malformation characterized by severe dilatation and elongation of the penile urethra. It causes functional obstruction of the lower urinary system. Herein, we present a newborn with congenital megalourethra with single umbilical artery.

Retinopathy of Prematurity in Triplets.

OBJECTIVES: To investigate the incidence, severity and risk factors of retinopathy of prematurity (ROP) in triplets. MATERIALS AND METHODS: The medical records of consecutive premature triplets who had been screened for ROP in a single maternity hospital were analyzed and presence and severity of ROP; birth weight, gender, gestational age of the infant; route of delivery and the mode of conception were recorded. RESULTS: A total of 54 triplets (40 males, 14 females) who were screened for ROP between March 2010 and February 2013 were recruited for the study. All triplets were delivered by Caesarean section and 36 (66.7%) were born following an assisted conception. During follow-up, seven (13%) of the infants developed ROP of any stage and two (3.7%) required laser photocoagulation. The mean gestational age of triplets with ROP was 27.6±1.5 (27-31) weeks whereas it was 32.0±1.5 (30-34) weeks in those without ROP (p=0.002). The mean birth weights of triplets with and without ROP were 1290.0±295.2 (970-1600) g and 1667.5±222.2 (1130-1960) g, respectively (p<0.001). The presence of ROP was not associated with gender (p=0.358) or mode of conception (p=0.674). CONCLUSION: ROP in triplets seems to be mainly related to low gestational age and low birth weight. Further prospective randomized studies are necessary to demonstrate risk factors of ROP in triplets and to determine if and how gemelarity plays a role in the development of ROP.

Hypertrophic Cardiomyopathy After a Single Dose of Dexamethasone in a Preterm Infant.

Dexamethasone is widely used in preterm infants with severe pulmonary disease. Hypertrophic cardiomyopathy (HCM) is a transient side effect observed after multiple doses of dexamethasone. We report a preterm infant with myocardial hypertrophy after a single dose of dexamethasone (0.5 mg/kg) used to treat laryngeal edema secondary to prolonged intubation. A benign course was observed without left ventricular outflow tract obstruction and with recovery within 4 weeks. Myocardial effects of dexamethasone may be independent of dose and duration of treatment. The risk/benefit ratio must be carefully considered before using even a single dose of dexamethasone in preterm infants.

Type VI Aplasia Cutis Congenita: Bart's Syndrome.

Bart's syndrome is characterized by aplasia cutis congenita and epidermolysis bullosa. We present the case of a newborn male who developed blisters on the mucous membranes and the skin following congenital localized absence of skin. Bart's syndrome (BS) is diagnosed clinically based on the disorder's unique signs and symptoms but histologic evaluation of the skin can help to confirm the final diagnosis. The patient was managed conservatively with topical antibacterial ointment and wet gauze dressing. Periodic follow-up examinations showed complete healing. We emphasized that it is important to use relatively simple methods for optimal healing without the need for complex surgical interventions.

Early-term delivery and adverse neonatal outcomes at a tertiary center in Turkey.

Early-term infants incur higher risks for neonatal morbidities compared to full-term infants. In this study, we investigated the neonatal morbidities in early-term infants admitted to a neonatal intensive care unit (NICU). Early-term (37 0/7 and 38 6/7 weeks of gestation) and full-term (39 0/7 and 41 6/7 weeks of gestation) infants born between January 2013 and December 2014 were enrolled in this study. Early-term deliveries accounted for 8,026 (25.7%) of all live births (n = 31,170). The admission rate of early-term infants to the NICU was 7.5%. The most common diagnoses were jaundice (44.2%) and respiratory distress (37.8%). The cesarean section and small-for-gestational-age rates were significantly higher in early-term infants (p < 0.001), as were the mean duration of hospital stay, prolonged hospitalization (> 5 days), and readmission rates (p< 0.05). Morbidities, including NICU admission, respiratory distress, jaundice, hypoglycemia, feeding difficulty, and dehydration, were also more common in early-term infants (p< 0.05). This is the first Turkish study to report on the association of early-term delivery with poor neonatal outcomes. These results should be evaluated by obstetricians when considering the timing of labor induction or planned cesarean delivery. They should also be considered by neonatologists, who need to be aware of the higher risk of neonatal morbidities.

Body temperature changes of newborns under fluorescent versus LED phototherapy.

OBJECTIVE: To determine changes in body temperature (BT) of hyperbilirubinemic newborns under conventional phototherapy with fluorescent lamps and light emitting diodes (LED) at different irradiances. METHODS: Otherwise healthy newborn infants >34 wk gestational age (GA) hospitalized for indirect hyperbilirubinemia, requiring phototherapy in the first 10 d of life were enrolled. Infants who received conventional phototherapy with fluorescent lamps (10-15 µW/cm(2)/nm irradiance) were defined as group 1, LED phototherapy of 26-60 µW/cm(2)/nm irradiance as group 2, and LED phototherapy of 60-120 µW/cm(2)/nm irradiance as group 3. Primary outcome measure was mean BT which was defined as arithmetical mean of axillary BT measured at 2 h intervals during the first day of phototherapy. RESULTS: Thirty patients were enroled in each group. Mean birth weight and GA of the total cohort was 2800 ± 530 g and 36.6 ± 2 wk, respectively. Baseline demographic variables and serum total bilirubin levels were similar among groups. Mean BT was 36.7 ± 0.1 °C in group 1, 36.6 ± 0.2 °C in group 2, 37.7 ± 0.2 °C in group 3. Mean BT was higher in group 3 compared to group 1 (p < 0.001) and group 2 (p < 0.001). Group 1 and group 2 had similar mean BT measurements (p = 0.09). During phototherapy all the patients in group 3 had at least one BT measurement ≥ 37.5 °C and 77 % had BT ≥ 38 °C. Only one patient in group 2 had BT ≥ 37.5 °C which was also ≥ 38 °C. During phototherapy all BT measurements were <37.5 °C in group 1. CONCLUSIONS: LED phototherapy of ≥ 60 µW/cm(2)/nm intensity significantly increases BT in hyperbilirubinemic newborns.

Effects of phototherapy using different light sources on oxidant and antioxidant status of neonates with jaundice.

BACKGROUND/AIM: Neonates have limited antioxidant protective capacity. It has recently been demonstrated that phototherapy used for treatment of neonatal jaundice produces oxidative stress. Various phototherapy devices using different light sources are available for phototherapy. We aimed to investigate the effects of phototherapy applied with different light sources on the global oxidant/antioxidant status in neonates. METHODS: Term and late-preterm (≥35 weeks) newborn infants hospitalized to receive phototherapy for non-hemolytic jaundice in the 2-9 days of life were enrolled. Infants who received conventional phototherapy with fluorescent lamps were defined as group 1, intensive light emitting diode (LED) phototherapy as group 2, and fiberoptic phototherapy as group 3. The serum total antioxidant capacity (TAC) and total oxidant status (TOS) were measured before and 24 h after phototherapy. Oxidative stress index (OSI) was calculated. RESULTS: Twenty nine patients were included in each group. At the beginning of phototherapy serum TAC, TOS and OSI levels were similar in all groups. After phototherapy serum TAC decreased significantly in all three groups (p < 0.001). Total oxidant status increased significantly in group 1 (p < 0.001) and group 2 (p = 0.001) whereas a statistically insignificant increase was observed in group 3 (p = 0.057). After phototherapy OSI increased significantly in group 1 (p < 0.001), group 2 (p = 0.001), and group 3 (p = 0.038). CONCLUSION: As indicated by increased OSI, oxidant/antioxidant balance is disturbed in favor of oxidants after blue fluorescent light, LED and fiberoptic phototherapy.
