Clinical and Laboratory Characteristics Predicting the Severity of Carbon Monoxide Poisoning in Children: A Single-Center Retrospective Study.

OBJECTIVES: Carbon monoxide poisoning (COP) is extremely common throughout the world. The purpose of this study was to assess the demographic, clinical, and laboratory characteristics predicting the severity COP in children. METHODS: The study included 380 children diagnosed with COP between January 2017 and January 2021 and 380 healthy controls. Carbon monoxide poisoning was diagnosed based on the medical history and a carboxyhemoglobin (COHb) level of more than 5%. The patients were classified as mild (COHb 10%), moderate (COHb 10%-25%), or severely (COHb > 25%) poisoned. RESULTS: The mean age of the severe group was 8.60 ± 6.30, for the moderate group was 9.50 ± 5.81, for the mild group was 8.79 ± 5.94, and for the control group was 8.95 ± 5.98. The most common place of exposure was at home and all cases were affected accidentally. The coal stove was the most common source of exposure, followed by natural gas. The most common symptoms were nausea/vomiting, vertigo, and headache. Neurologic symptoms such as syncope, confusion, dyspnea, and seizures were more common in the severe group. A total of 91.3% of the children had hyperbaric oxygen therapy, 3.8% were intubated, and 3.8% were transferred to intensive care in the severe group, whereas no death or sequela was observed. Mean platelet volume and red cell distribution width had the highest area under the curve in the receiver operating characteristic analysis (0.659; 0.379). A positive and low statistically significant relationship was found between COHb levels and troponin and lactate levels in the severe group ( P < 0.05). CONCLUSIONS: Carbon monoxide poisoning progressed more severely in children presented with neurological symptoms and have elevated red cell distribution width and mean platelet volume. Even in severe COP cases, satisfactory results have been obtained with early and appropriate treatment.

A novel deletion involving exon 13 of factor VIII gene in a newborn with splenic hematoma.

Splenic hematoma is an exceptionally rare event in newborn period that usually occurs in concomitant birth trauma and bleeding disorder. This report presents a newborn case with severe hemophilia A, who had a splenic hematoma presented on the second day of life with severe anemia, abdominal distention, abdominal and scrotal ecchymosis. The patient was successfully treated medically with factor VIII concentrates without splenectomy. Molecular analysis of the factor VIII gene revealed a hemizygous deletion in exon 13.

Iodine deficiency: a probable cause of neural tube defect.

INTRODUCTION: Iodine deficiency is the most devastating event in developing brain in the fetus and neonate. Iodine is absolutely necessary on the myelination, neuronal differentiation, and formation of neural processes, synaptogenesis, and neuronal migration by thyroidal hormones throughout pregnancy and shortly after birth. Neural tube defects (NTD) form after third and fourth gestational weeks and their etiologies are multifactorial. CASE REPORT: We herein present a male newborn with iodine deficiency and thoracic neuroenteric cyst bound to a myelomeningocele via a pedinculi. We hypothesize that iodine deficiency may be a cause of NTD, and iodine supplementation in preconception and pregnancy may prevent NTD.

Asymmetric crying face in a newborn with isotretinoin embryopathy.

We report a newborn with asymmetric crying face and other anomalies whose mother had taken isotretinoin during the first month of pregnancy. We hypothesize that asymmetric crying face is a finding of retinoic acid embryopathy and results from the intrauterine effects of retinoic acid on the development of the depressor anguli oris muscle or the mandibular branch of the facial nerve.

Pediatricians` attitudes, practices, and perceived barriers to school readiness.

BACKGROUND: School readiness (SR) has been adopted by the American Academy of Pediatrics (AAP) as a component of health supervision, but the medical community`s role is unknown. We evaluated the pediatricians` attitudes, practices, and perceived barriers to SR. METHODS: This multicenter, cross-sectional descriptive study was performed among 787 general pediatricians, pediatric residents, subspecialists, and subspecialty fellows. A 41-item survey was administered. RESULTS: Forty-nine point two percent of the pediatricians defined SR as a multidimensional issue, as outlined by the AAP, whereas 50.8% defined it as the child`s set of skills or passing the SR tests. Three-quarters of pediatricians believed that SR assessment tests are necessary before starting school, and children who do not appear ready should wait a year. To promote SR, the rates of usually fostering at least four of the five `Rs` (reading, rhyming, routines, rewarding, relationships) and integrating developmental surveillance into daily practice were 37.8% and 23.8%, respectively. Only 2.2% of pediatricians usually inquired about eight adverse childhood experiences (ACEs), and 68.9% did not usually ask about any. Usually fostering at least four of the five `Rs` was associated with usually integrating developmental surveillance (p < 0.001), usually inquiring about each ACE (p < 0.001), and being perceived as responsible for promoting SR (p < 0.01). Training on SR during pediatric residency was 2.7%. Time constraints and insufficient knowledge were the most common barriers. CONCLUSIONS: Pediatricians were not familiar with the concept of SR and had some misconceptions. There is a need for additional training regarding pediatricians` roles in promoting SR along with addressing multiple, modifiable barriers within the health system. < strong > Supplementary: < a href="https://www.turkishjournalpediatrics.org/uploads/2573-supplementary.pdf" target=`_blank` > Supplementary Appendix < /a > < /strong >.

Neonatal Resuscitation Practices in Turkey: A Survey of the Turkish Neonatal Society and the Union of European Neonatal and Perinatal Societies.

OBJECTIVE: Optimal care in the delivery room is important to decrease neonatal morbidity and mortality. We aimed to evaluate neonatal resuscitation practices in Turkish centers. MATERIALS AND METHODS: A cross-sectional survey consisted of a 91-item questionnaire focused on delivery room practices in neonatal resuscitation and was sent to 50 Turkish centers. Hospitals with <2500 and those with ≥2500 births/year were compared. RESULTS: In 2018, approximately 240 000 births occurred at participating hospitals with a median of 2630 births/year. Participating hospitals were able to provide nasal continuous-positiveairway-pressure/high-flow nasal cannula, mechanical ventilation, high-frequency oscillatory ventilation, inhaled nitric oxide, and therapeutic hypothermia similarly. Antenatal counseling was routinely performed on parents at 56% of all centers. A resuscitation team was present at 72% of deliveries. Umbilical cord management for both term and preterm infants was similar between centers. The rate of delayed cord clamping was approximately 60% in term and late preterm infants. Thermal management for preterm infants (<32 weeks) was similar. Hospitals had appropriate equipment with similar rates of interventions and management, except conti nuous-positive-airway-pressure and positive-end-expiratory-pressure levels (cmH2O) used in preterm infants (P = .021, and P = .032). Ethical and educational aspects were also similar. CONCLUSIONS: This survey provided information on neonatal resuscitation practices in a sample of hospitals from all regions of Turkey and allowed us to see weaknesses in some fields. Although adherence to the guidelines was high among centers, further implementations are required in the areas of antenatal counseling, cord management, and circulation assessment in the delivery room.

Cerebellar hemangioblastoma associated with diffuse neonatal hemangiomatosis in an infant.

INTRODUCTION: Hemangioblastomas (HBLs) comprise approximately 2% of all primary central nervous system (CNS) tumors. Although histological features of this rare tumor are generally benign, its outcome is often unfavorable due to high risk of recurrence and multifocal localization. HBLs can be detected as sporadic or associated with Von Hippel-Lindau disease. Diffuse neonatal hemangiomatosis (DNH) presents with multiple, progressive, rapidly growing cutaneous hemangiomas associated with widespread visceral hemangiomas in the liver, lungs, gastrointestinal tract, brain, and meninges. DNH with predominant CNS involvement is rarely reported. Herein, we present a neonatal case of cerebellar HBL associated with DNH. CASE REPORT: A 5-day-old male baby was referred with complaints of multiple cutaneous lesions. Purple papules were noted on the trunk, extremities, and the head. Thoracic magnetic resonance imaging demonstrated multiple hyperintense lesions on the chest wall and apex of the right lung. On MRI, a 3×2-cm mass lesion in the right cerebellar hemisphere was detected. Total resection of the mass and ventriculoperitoneal shunting was performed. Histopathologic examination confirmed the diagnosis of HBL. Steroid therapy was administered for disseminated hemangiomatosis, and the lesions showed regression; the patient showed good clinical recovery. The parents refused further treatment, and he was out of our control when he was 9 months old. CONCLUSION: According to our knowledge, the presented newborn is the second case of cerebellar HBL associated with diffuse skin and visceral hemangiomas in the English medical literature. Clinicians must be vigilant about the predictive value of visceral and/or cutaneous hemangioma for an associated intracranial HBL.

Neonatal gastrointestinal mucormycosis in an asphyxiated premature newborn.

Mucormycosis of the intestine is a rare fungal infection of childhood and is mostly encountered in neonates. It is a potentially lethal opportunistic fungal infection with rapid progression and high mortality in immunocompromised patients. The number of reported cases with intestinal mucormycosis is 19 to date. We herein report an asphyxiated preterm infant with intestinal mucormycosis who was presented with an atypical necrotizing enterocolitis (NEC), with findings similar to an intraabdominal mass. The diagnosis was made in the postmortem examination of the surgically removed bowel segment. Prematurity and asphyxia are important risk factors for mucormycosis. We suggest that the diagnosis of gastrointestinal mucormycosis should be considered in the differential diagnosis of atypical NEC cases.

Transcutaneous Bilirubin Levels and Risk of Significant Hyperbilirubinemia in Early-Term and Term Newborns.

OBJECTIVE: To compare the course of the transcutaneous bilirubin (TcB) values of early-term newborns with those of term newborns in the first month of life and to investigate whether early-term newborns have an increased risk of significant hyperbilirubinemia requiring treatment. DESIGN: A prospective, controlled cohort analysis. SETTING: A tertiary level mother-child birth and health care center. PARTICIPANTS: Four hundred early-term (37 0/7 to 38 6/7 weeks) and 320 term (39 0/7 to 41 6/7 weeks) newborns born during a 27-month period. METHODS: A total of six TcB measurements in a longitudinal manner were made in early-term and term newborns: the first two at 6 and 48 hours after birth and the next four on routine examination days (Days 4, 7, 15, and 30). Demographic characteristics, values of daily TcB measurements, number of newborns with significant hyperbilirubinemia, and risk of jaundice requiring treatment were compared between the two groups. RESULTS: All six TcB values were significantly greater in the early-term group than in the term group (p < .001 for each). Early-term newborns had a statistically significant increased risk of jaundice requiring treatment compared to term newborns (risk ratio = 1.91; 95% confidence interval [1.23-2.96]; p = .0046). Results of the repeated-measures analysis of variance and post hoc adjusted multiple comparison analysis showed that TcB levels increased to and peaked at 96 hours after birth and then gradually decreased to baseline (first measurement) levels at 30 days after birth in each group. CONCLUSIONS: Early-term newborns should not be treated as full-term newborns because they have significantly higher TcB levels. These newborns should be closely monitored for pathologic jaundice because they have increased risk for significant hyperbilirubinemia requiring phototherapy.

Vitamin D Deficiency Prevalence in Late Neonatal Hypocalcemia: A Multicenter Study

Objective: Late neonatal hypocalcemia (LNH) is a common metabolic problem associated with hypoparathyroidism, high phosphate intake and vitamin D deficiency, often presenting with seizures. In this cross-sectional study, we aimed to evaluate the role of vitamin D deficiency in LNH in Turkey and to describe the characteristics of affected newborns. Methods: Conducted with a cross-sectional design and with the participation of 61 neonatal centers from December 2015 to December 2016, the study included term neonates with LNH (n=96) and their mothers (n=93). Data were registered on the FAVOR Web Registry System. Serum samples of newborns and mothers were analyzed for calcium, phosphate, magnesium, albumin, alkaline phosphatase, intact parathyroid hormone (iPTH) and 25 hydroxyvitamin D [25(OH)D] levels. Results: The median (range) onset time of hypocalcemia was 5.0 (4.0-8.0) days of age, with a male preponderance (60.4%). The median (range) serum 25(OH)D levels of the neonates and their mothers were 6.3 (4.1-9.05) and 5.2 (4.7-8.8) ng/mL, respectively. The prevalence of vitamin D deficiency (<12 ng/mL) was high in both the neonates (86.5%) and mothers (93%). Serum 25(OH)D levels of the infants and mothers showed a strong correlation (p<0.001). While the majority (93.7%) of the neonates had normal/high phosphorus levels, iPTH levels were low or inappropriately normal in 54.2% of the patients. Conclusion: Vitamin D deficiency prevalence was found to be high in LNH. Efforts to provide vitamin D supplementation during pregnancy should be encouraged. Evaluation of vitamin D status should be included in the workup of LNH.

Investigation of the relationship between cord clamping time and risk of hyperbilirubinemia.

BACKGROUND: Although the relationship between umbilical cord clamping time and various parameters such as hemoglobin (Hb) levels, iron deficiency, and risk of neonatal jaundice has previously been studied, to the best of our knowleadge there have been no studies investigating the relationship between cord clamping time and the risk of significant hyperbilirubinemia. We aimed to investigate the relationship between the time of umbilical cord clamping and transcutaneous bilirubin (TcB) measurements made on various postnatal hours, Hb and serum total bilirubin (STB) levels measured on postnatal 4th day, and the risk of development of significant hyperbilirubinemia requiring phototherapy treatment. METHODS: Eligible newborns were divided into two groups on the basis of the time of cord clamping: those clamped late (60 seconds or more; Group I) and those clamped early (less than 60 seconds; Group II). Groups were compared with respect to the parameters of cord Hb, postnatal TcB measurements at 6th, 48th, 96th and 168th hours, and 96th hour Hb, STB and direct bilirubin levels. RESULTS: TcB levels at the 96th and 168th hour were significantly higher in Group I when compared to Group II (p < 0.001 and p < 0.001, respectively). The 96th hour STB level was significantly higher in Group I when compared to Group II (p < 0.001). The need of phototherapy requirement was higher in Group I when compared to Group II (p=0.001). Increase in cord blood Hb for each 1 gr/dl caused a 3.94-fold increased risk in the requirement of phototherapy treatment. Cord clamping time showed statistically significant positive correlations with both cord blood and 96th hour venous Hb levels, with both 96th hour and 168th hour TcB levels, and with 96th hour STB levels. CONCLUSIONS: Newborns whose cords are clamped late should be followed up closely with respect to high postnatal bilirubin levels and other risks associated with significant hyperbilirubinemia requiring phototherapy treatment.

Association Between Early Idiopathic Neonatal Jaundice and Urinary Tract Infections.

BACKGROUND AND PURPOSE: Etiologic role, incidence, demographic, and response-to-treatment characteristics of urinary tract infection (UTI) among neonates, its relationship with significant neonatal hyperbilirubinemia, and abnormalities of the urinary system were studied in a prospective investigation in early (⩽10 days) idiopathic neonatal jaundice in which all other etiologic factors of neonatal hyperbilirubinemia were ruled out. PATIENTS AND METHODS: Urine samples for microscopic and bacteriologic examination were obtained with bladder catheterization from 155 newborns with early neonatal jaundice. Newborns with a negative urine culture and with a positive urine culture were defined as group I and group II, respectively, and the 2 groups were compared with each other. RESULTS: The incidence of UTI in whole of the study group was 16.7%. Serum total and direct bilirubin levels were statistically significantly higher in group II when compared with group I (P = .005 and P = .001, respectively). Decrease in serum total bilirubin level at the 24th hour of phototherapy was statistically significantly higher in group I compared with group II (P = .022). CONCLUSIONS: Urinary tract infection should be investigated in the etiologic evaluation of newborns with significant hyperbilirubinemia. The possibility of UTI should be considered in jaundiced newborns who do not respond to phototherapy well or have a prolonged duration of phototherapy treatment.

Evaluation of aortic intima-media thickness in newborns with Down syndrome.

BACKGROUND: Health care programs for children with Down syndrome (DS) help improve the overall outcome and quality of life of these children. It is therefore very important to focus on the most common and serious problems of these patients, such as congenital heart defects and cardiac problems, and to keep medical guidelines updated with regard to these problems. OBJECTIVES: The aim of this study was to evaluate aortic intima-media thickness (aIMT), lipid profiles and blood pressure in DS patients in comparison with a control group of ageand gender-matched neonates without DS. MATERIAL AND METHODS: Serum concentrations of lipids (total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglyceride), blood pressure and abdominal aIMT were measured in newborns with DS, and compared with the measurements from ageand gender-matched newborns without DS. RESULTS: No statistically significant differences between the 2 groups of newborns were detected with respect to aIMT, lipid levels or blood pressure. CONCLUSIONS: This study represents the first investigation of aIMT - one of the most important indicators of atherosclerosis - in DS patients, but neither a significantly increased aIMT, nor any significant changes in lipid profiles or blood pressure were detected in this group of patients. Whether aIMT differs according to the type of congenital heart defect (such as atrial septal defect, ventricular septal defect, patent ductus arteriosus, and atrioventricular septal defect) among DS patients remains to be determined in future studies.

Quantitative assessment of hepatic blood flow in the diagnosis and management of necrotizing enterocolitis.

BACKGROUND: Necrotizing enterocolitis (NEC) is the most important gastrointestinal emergency in the neonatal period and early detection is very important for its management. Bowel ischemia-hypoperfusion is one of the main etiological factors. In the literature, a few studies have focused on arterial Doppler ultrasonography (DUS) features of splanchnic arteries; however, their clinical implications are not clear. OBJECTIVE: In this study, we aimed to quantitatively evaluate the blood flow features in the hepatic portal vein (PV) and hepatic veins (HVs) by using DUS in newborns with NEC. Patient-Method: Enrolled subjects were divided into two groups as patient (suspected/confirmed NEC, n = 24), and control group (n = 25). Daily serial DUS examinations were performed after the onset of the suspicion of NEC and continued until the initial day of the enteral feeding. Portal blood flow (PBF) and "hepatic blood flow ratio" (RHBF) were calculated manually by using DUS findings. Two groups were compared with respect to their PBF and RoHBF values. RESULTS: PBF and RHBF levels were significantly lower in patient group than those in control group. Clinical improvement in patients with NEC was associated with improvement in the PBF and RHBF. Cut-off level of the RHBF for the diagnosis of NEC was 0.66. CONCLUSION: DUS seems to be useful for the diagnosis and follow-up of NEC by providing quantitative information on liver blood flow. Daily measurements of the PBF and RoHBF in newborns with NEC may be beneficial to make the decision of starting enteral feeding.

Coexistence of Anal Atresia, Anophthalmia and Intestinal Neuronal Dysplasia Type-A in a Newborn.

We report a patient with anal atresia, anophthalmia and intestinal neuronal dysplasia type A.

Investigation on malondialdehyde, S100B, and advanced oxidation protein product levels in significant hyperbilirubinemia and the effect of intensive phototherapy on these parameters.

BACKGROUND: The parameters of oxidative stress [advanced oxidation protein products (AOPPs), malondialdehyde (MDA), and S100B] and the effect of intensive phototherapy (PT) on these parameters have not been studied extensively in newborns with significant hyperbilirubinemia (SH). We aimed to measure the levels of MDA, S100B, and AOPPs in newborns with SH, and to compare newborns with healthy control newborns without hyperbilirubinemia on the basis of these parameters of oxidative stress. In addition, we investigated the effect of intensive PT on these parameters during the treatment of SH and report our findings for the first time in the literature. METHODS: The study was performed in newborns (n = 62) who underwent intensive PT because of SH. Newborns without jaundice constituted the control group (n = 30). Both groups were compared with respect to demographic characteristics and biochemical (laboratory) parameters including MDA, AOPPs, and S100B. MDA, AOPPs, and S100B were also compared before and after intensive PT in the PT group. In the study group, a correlation analysis of demographic characteristics; MDA, AOPP, and S100B values; and changes occurring in MDA, AOPPs, and S100B values due to the effect of intensive PT was performed. RESULTS: Serum total bilirubin, S100B, and MDA levels in the PT group before performing PT were significantly higher than those in the control group. In newborns receiving PT serum total bilirubin, MDA and AOPP levels decreased significantly after intensive PT. In correlation analysis, a statistically significant negative correlation was found only between the amount of bilirubin decrease with PT and AOPP levels after PT in the study group. CONCLUSION: Whether the significant decrease in MDA levels, which was higher prior to PT, is due to the decrease in serum bilirubin levels or due to the effect of intensive PT itself remains to be determined in further studies. The decrease in AOPP levels after PT implies that intensive PT has protective effects on oxidative stress.

A Neonate with CLOVES Syndrome.

Congenital lipomatous overgrowth, vascular malformations, and epidermal nevi (CLOVE) syndrome is a recently delineated disorder that comprises vascular malformations (typically truncal), dysregulated adipose tissue, scoliosis, enlarged bony structures (typically of the legs) without progression, or distorting bony overgrowth. The name CLOVE was subsequently extended to CLOVES to emphasize the association with scoliosis/skeletal and spinal anomalies and seizures/central nervous system malformations. We herein report a very rare case of CLOVES syndrome with the findings of lipomatous overgrowth in the cheek (facial asymmetry), vascular malformation (hemangiomas), epidermal nevi (large port wine stains), and skeletal abnormalities (widened first interdigital space, dystrophia in the nail of the first digit of the right foot, and bilateral hypertrophy of the first digits of the feet).

Endocrine abnormalities of patients with cleft lip and/or cleft palate during the neonatal period.

BACKGROUND/AIM: There are close interactions among the developing oral cavity, pituitary gland, and central nervous system (CNS) in early embryonic life. In this study we aimed to screen endocrine abnormalities in patients with orofacial clefts in the neonatal period. MATERIALS AND METHODS: Thirty-one patients with isolated orofacial median clefts wereincluded in the study. Pituitary, thyroid, and adrenal hormones were measured at the first week and remeasured in the third or fourth weeks. Imaging studies were done for detection of CNS anomalies in all patients. RESULTS: Endocrine abnormality was detected in 22 (70.9%) patients. The number of patients with single and multiple endocrine abnormalities were 13 (41.9%) and 9 (29%), respectively. Thyroid hormone-related disorders were detected in 10 (32.3%) patients. Growth hormone deficiency was detected in 4 (12.9%) patients. Adrenocorticotrophic hormone and/or glucocorticoid deficiency was detected in 5 (16.1%) patients. Neonatal hypoglycemia due to endocrinological abnormalities was detected in 6 (19.4%) patients. Defected mini-puberty was seen in 2 (15.4%) patients. There was no relationship between the types of orofacial cleft and endocrine abnormalities. CONCLUSION: Endocrinological evaluation of the patients with orofacial clefts in the neonatal period is a worthwhile endeavor to detect hormone deficiencies regardless of the type of the cleft.
