Accidental ingestion of 3% hydrogen peroxide in the neonatal period.

Hydrogen peroxide (H2O2) is an oxidizing agent. High concentrations of H2O2 are used in the chemical industry, and 3% concentrations are used in household disinfectants. Severe H2O2 toxicity occurs with a 35% concentration. After poisoning with H2O2, corrosive damage occurs. We describe a 3-day-old male who ingested H2O2 accidentally and was treated with supportive care. Hydrogen peroxide intoxication usually occurs in adults accidentally. This is the first report of a newborn case of H2O2 ingestion.

Evaluation of Newborns Diagnosed with COVID-19: A Single-Center Experience.

OBJECTIVE: The causative agent of the severe acute respiratory syndrome is a new type of coronavirus infection called coronavirus disease-2019 (COVID-19) which has spread around the world. COVID-19 is thought to rarely affect infants, so pandemic planning focuses on adults. This study aimed to share our 1-year experience with COVID-19-positive newborns in a tertiary neonatal intensive care unit (NICU). STUDY DESIGN: Hospitalized newborns after a reverse transcription polymerase chain reaction (RT-PCR) for COVID-19 were evaluated in this retrospective, cohort study between March 2020 and March 2021. The clinical course, laboratory tests, imaging studies, and outcomes of affected newborns were collected from medical records. RESULTS: Eleven COVID-19-diagnosed newborns were analyzed in our study. Four (36.6%) patients had contact with a COVID-19-positive individual in their families. The main symptoms were fever (81.8%), hypoxemia (63.6%), and tachypnea (63.6%). Bacterial coinfection was identified in two newborns. Aortic coarctation was detected as an accompanied disease by a newborn who was referred to our hospital with a suspicion of congenital heart disease and two patients had a bacterial coinfection. We did not detect any cases of neonatal multisystem inflammatory syndrome. All patients were discharged in good health. None of the newborns had any complications and repeated infection with another variant during the first-year follow-up. CONCLUSION: Contrary to popular belief, newborns are a sensitive age group for COVID-19 and need a high rate of hospitalization. Congenital heart diseases and coinfections should not be overlooked in COVID-19-infected newborns. The acquired immunity due to COVID-19 infection protects newborns from recurrent COVID-19 infections in their first year of life. The absence of COVID-19-positive individual in the family in most cases suggests that PCR-negative adults may also play a role in the transmission of the disease. KEY POINTS: · COVID-19 is still a pandemic all over the world.. · COVID-19 is dangerous for newborns.. · PCR-negative adults may also play a role in the transmission of the disease to the newborn..

Efficiency of Lung Ultrasonography in the Diagnosis and Follow-up of Viral Pneumonia in Newborn.

OBJECTIVE: Lung ultrasonography (LUS) is a useful method for diagnosis of lung diseases such as respiratory distress syndrome, transient tachypnea of the newborn, pneumonia, and pneumothorax in the neonatal period. LUS has become an important tool in the diagnosis and follow-up of lung diseases. LUS is easy to apply at the bedside and is a practical and low-cost method for diagnosing pneumonia. STUDY DESIGN: This study was conducted in neonatal intensive care unit of Dr. Sami Ulus Obstetrics, Children's Health and Diseases Training and Research Hospital. From September 2019 to April 2020, 50 patients who were diagnosed with viral pneumonia were included in the study. Also, 24 patients with sepsis-related respiratory failure were included in the study as a control group. LUS was performed at the bedside three times, by a single expert, once each before treatment for diagnosis, on discharge, and after discharge in outpatient clinic control. RESULTS: Before treatment, LUS findings were lung consolidation with air bronchograms (50/50), pleural line abnormalities (35/50), B-pattern (25/50), disappearance of lung sliding (21/50), lung pulse (5/50), and pleural effusion (9/50). During discharge, we found significant changes: lung consolidation with air bronchograms (6/50), pleural line abnormalities (7/50), B-pattern (12/50), and pleural effusion (1/50) (p < 0.05). Outpatient clinic control LUS findings were lung consolidation with air bronchograms (0/50), pleural line abnormalities (0/50), B-pattern (0/50), disappearance of lung sliding (0/50), and pleural effusion (0/50) (p < 0.05). Also, B-pattern image, disappearance of lung sliding, and pleural line abnormalities were higher in control group (p < 0.05). CONCLUSION: Ultrasound gives no hazard, and the application of bedside ultrasonography is comfortable for the patients. Pneumonia is a serious infection in the neonatal period. Repeated chest radiography may be required depending on the clinical condition of the patient with pneumonia. This study focuses on adequacy of LUS in neonatal pneumonia. KEY POINTS: · Lung ultrasound is a practical and low-cost method in diagnosing pneumonia.. · Neonatal pneumonia is a very important cause of morbidity and mortality in NICU.. · We can evaluate neonatal pneumonia with combination of clinical presentations and LUS findings..

Supraventricular tachycardia after respiratory syncytial virus infection in a newborn.

Respiratory syncytial virus (RSV) is a common cause of lower respiratory tract infections in newborn infants. RSV can cause cardiac arrhythmias. We present a case of a term newborn with supraventricular tachycardia that developed during RSV infection and was successfully treated with amiodarone. RSV infection increases the risk of cardiac arrhythmia due to its course and the agents used in the treatment; therefore, close cardiac monitoring is required.

Role of systemic immune-inflammatory index in early diagnosis of sepsis in newborns with CHD.

OBJECTIVE: Congenital heart diseases (CHD) are the most common causes of birth defects that have increased the risk of infections. Neonatal sepsis is a life-threatening condition and early diagnosis can be life-saving. We aimed to evaluate the potential role of the systemic immune-inflammatory index in the early diagnosis of neonatal sepsis. METHODS: A retrospective cohort study was conducted on 166 newborns with a diagnosis of neonatal sepsis who were admitted to our hospital with CHD between January 2017 and June 2021. Haematological indices including neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and systemic immune-inflammatory index were calculated for all patients at the time of diagnosis of neonatal sepsis (sepsis). The sepsis values of these indices were compared with the admission values (pre-sepsis) of the patients. RESULTS: The mean gestational age and birth weight of the patients were 38.36 ± 1.42 weeks and 3057.75 ± 484.68 g. It was found that absolute neutrophil count, systemic immune-inflammatory index, neutrophil/lymphocyte ratio, but not platelet/lymphocyte ratio were significantly increased at the time of sepsis. The receiver operating characteristic curve showed that systemic immune-inflammatory index, neutrophil/lymphocyte ratio, and absolute neutrophil count have predictive ability to define neonatal sepsis among newborns with CHD. The systemic immune-inflammatory index produced an area under the curve receiver operating characteristic curve of 0.76 (70% sensitivity, 70.5% specificity). To discriminate neonatal sepsis, the cut-off values of systemic immune-inflammatory index, neutrophil/lymphocyte ratio, and absolute neutrophil count were 517.19, 2.62, and 9210/mm3, respectively. CONCLUSION: As an easily accessible and reliable indicator, systemic immune-inflammatory index may be used in combination with the other parameters in the early diagnosis of neonatal sepsis.

Lactobacillus rhamnosus Sepsis Associated with Probiotic Therapy in a Term Infant with Congenital Heart Disease.

BACKGROUND: Congenital heart diseases (CHD) are the most common birth defects. Necrotizing enterocolitis (NEC) is an important cause of morbidity and mortality in premature infants, and probiotics can be used to protect NEC. CASE REPORT: We present a term infant with aortic coarctation who developed sepsis with Lactobacillus rhamnosus GG after probiotic use, successfully treated with ampicillin. The baby unfortunately died of acute cardiac arrest on the 90th day of life. CONCLUSION: Probiotic-associated sepsis may develop in infants with various risk factors such as central catheterization, long-term mechanical ventilation and in those at risk for NEC.

The Serum Levels of Asymmetric Dimethylarginine, Vascular Endothelial Growth Factor, and Insulin-Like Growth Factor-1 in Preterms with Retinopathy of Prematurity.

Objective:To determine the serum levels of asymmetric dimethylarginine (ADMA), vascular endothelial growth factor (VEGF), and insulin-like growth factor-1 (IGF-1) in preterms with retinopathy of prematurity (ROP). Materials and Methods: We included 37 preterm infants. The first blood samples were obtained within the first 5 days of life and repeated at the time of the first ophthalmologic examination for ROP. The levels of ADMA, IGF-1, and VEGF were measured in all samples. Results: ROP was detected in 12 of the subjects (32.4%). We categorized the subjects as non-ROP (Group 1; n = 25), untreated ROP (Group 2; n = 7), and treated ROP (Group 3; n = 5) according to the eye findings. There were no significant differences among the groups for serum levels of ADMA, VEGF, and IGF-1 at the first sampling. Conclusion: We did not find any differences in terms of serum ADMA, IGF-1, and VEGF levels in preterm infants with or without ROP.

The role of thiol-disulfide homeostasis in neonatal sepsis.

BACKGROUND AND AIM: The thiol-disulfide homeostasis is essential for the body to maintain effective antioxidant defense mechanisms. We aimed to show the relationship between sepsis and thiol-disulfide homeostasis in newborns. MATERIALS AND METHODS: In this prospective study, 66 newborns with sepsis (group 1) and 51 healthy controls (group 2) were included. In group 1, 53 newborns were diagnosed as clinical sepsis (group 1a) and 13 as definite sepsis (group 1b). The study has two time points; the day of diagnosis (step 1) and three days after the treatment (step 2). At step 1, group 1 and group 2 were compared for thiol-disulfide homeostasis as well as inflammatory markers. At step 2, the same laboratory tests were repeated only in group 1. RESULTS: At step 1, the levels of C-reactive protein (CRP) and interleukin-6 (IL-6) were higher, while native thiol and total thiol levels were lower in group 1 compared to controls. Serum disulfide/total thiol ratio was also significantly higher in group 1. When analyzed for subgroups of group 1, demonstration of microorganism did not affect the serum thiol levels. Within group 1, at step 2, although CRP and IL-6 levels were significantly lowered compared to step 1, we did not observe significant changes in thiol-disulfide parameters. CONCLUSIONS: The thiol-disulfide homeostasis may have a role in the pathogenesis of sepsis in newborns. The related parameters might be new markers for the diagnosis of sepsis in newborn patients. Further studies are needed to define the role of thiol-disulfide homeostasis in the course of neonatal sepsis.

Comparison of three natural surfactants according to lung ultrasonography scores in newborns with respiratory distress syndrome.

INTRODUCTION: Lung ultrasonography (LUS) is a noninvasive bed-side test and increasingly used by clinicians in the management and follow-up of respiratory distress syndrome (RDS) in premature infants. OBJECTIVE: To compare the results of three natural surfactants according to LUS scores in premature infants with RDS. METHODS: This was a prospective study on 62 preterm infants (25-34 weeks) with RDS and receiving surfactant according to 2016 European guidelines. All patients underwent a clinical evaluation and chest X-ray at three study points; at the first hours of life (presurfactant), and at 6-12th hour (early postsurfactant) and 24th hour (late postsurfactant) of surfactant. Simultaneously fractional inspired oxygen (FiO2) need, arterial PaO2 values, Downes and LUS scores were noted. The patients were randomized into three groups; Group 1 (n = 23), poractant alpha; Group 2 (n = 20), beractant; and Group 3 (n = 19), calfactant. The groups were compared according to clinical, laboratory and radiological variables as well as LUS scores. RESULTS: Gestational age (p = .05), birthweight (p = .07), and SNAPPE-II scores (p = .57) were similar in three groups. Repeated dose need was the highest in Group 3 (p = .04). FiO2 need (p = .04) was the highest and PaO2 values (p = .03) were the lowest at late postsurfactant point in the same group. LUS scores were also the highest in Group 3 at this period (p = .02). Downes scores were similar in groups at all points (p > .05). NICU stay were similar in groups (p = .53). The durations of total oxygen supplementation, mechanical ventilation, and hospital stay were the same in groups (p > .05). CONCLUSIONS: In newborns with RDS, poractant alpha and beractant have similarly reduced oxygen need in accordance to the LUS findings. However, they seem to be superior compared to calfactant.

Preventative and therapeutic effects of fennel (Foeniculum vulgare) seed extracts against necrotizing enterocolitis.

We aimed to understand the efficacy of fennel (Foeniculum vulgare: FV) extract in an experimental necrotizing enterocolitis (NEC) model. Forty-two rat pups were divided into three groups as NEC, NEC treated with fennel extract, and control. At the end of the experiment, tissue samples were taken from the proximal colon and ileum for biochemical and immuno-histological studies including hematoxylin-eosin and Caspase-3-8-9 immunohistochemical staining. Bowel damage and apoptosis were found to be less in the NEC + FV group. Oxidant stress, caspase 3, TNF-α, and IL-6 levels were considerably decreased in the NEC + FV group. Antioxidants were significantly higher in the NEC + FV group more than in the NEC group. Moreover, protein, DNA damage, and lipid peroxidation were found to be decreased in the NEC + FV group compared to the NEC group. PRACTICAL APPLICATIONS: Intense inflammation, oxidant stress, apoptosis, and infection are important in the development of NEC. Fennel has anti-oxidant, anti-inflammatory, antibacterial, antifungal, antiviral, immunomodulatory effects. Fennel extract might be a novel option in the treatment of NEC through its anti-oxidant, anti-inflammatory, anti-apoptotic, and cytoprotective features.

Predictive Value of Vasoactive-inotropic Score for Mortality in Newborns Undergoing Cardiac Surgery.

OBJECTIVE: Vasoactive-inotropic Score (VIS) was developed to quantify the amount of inotropic support provided in the postoperative period. We investigated the predictive value of (VIS) for mortality in neonates with congenital heart disease (CHD). STUDY DESIGN: Prospective cohort. PATIENTS: 119 newborns who underwent cardiac surgery. SETTING: Tertiary NICU-CHD center of Ankara from November 2016 to January 2019. INTERVENTION/MEASUREMENT: VIS values were calculated by a standard formula for the first 72 postoperative hours, and the maximum score was recorded. PRIMARY OUTCOMES: Duration of mechanical ventilation, NICU length of stay, and mortality. RESULTS: At surgery, the median (IQR) age was 15 d (9-31). The patients were divided into two groups according to mortality; Group 1 (Non-survivors) (n=36) and Group 2 (Survivors) (n=83). Higher VIS score was correlated to longer duration of mechanical ventilation (P=0.009, r=0.33), and was higher among patients who died (P=0.003). Area under the curve (AUC) was 0,83 (P<0.001, CI: 95% 0.7-0.9) for VIS to identify mortality. At a cut-off value of 15.5, sensitivity and negative predictive values of VIS for mortality were 73.6% and 85.3%, respectively. The higher VIS (>15.5) was independently associated with increased odds for mortality (OR: 8.1, 95% CI: 1.8-35.7, P=0.005). CONCLUSIONS: In newborns with CHD, a higher VIS within 72 hours after cardiac surgery is associated with increased duration of mechanical ventilation, and mortality. VIS may be useful for prediction of mortality at early postoperative period.

Central Diabetes Insipidus in an Infant with Pneumococcal Meningitis.

BACKGROUND: Central diabetes is an infrequent complication reported in the neonatal period. CASE REPORT: CDI as a complication of Streptococcus pneumoniae (S. pneumoniae) sepsis and meningitis in a 9-day-old boy is presented. The CDI developed on day 3 after admission and was controlled with nasal vasopressin on the 20th day of admission. Despite antibiotic support, the child died from Acinetobacter sepsis at 4 months of age, but the CDI was well controlled. CONCLUSION: Newborns with bacterial meningitis can develop CDI as a sequalae. Treatment of the CDI with nasal vasopressin can be successful in this period. To our knowledge, this is the first newborn of CDI associated with S. pneumoniae meningitis.

Tai Chi vs. combined exercise prescription: A comparison of their effects on factors related to falls.

BACKGROUND: Regular exercise training is one of the core components of multifactorial fall-prevention programs. OBJECTIVE: To compare the effect of Tai Chi and combined exercise prescription that consists of three main components of an exercise prescription on static balance, dynamic balance, fear of falling and mood. METHODS: Sixty older adults aged 55-76 were randomly assigned to Group 1 (Tai Chi exercise) or Group 2 (combined exercise prescription). Exercise was performed three times a week over a period of 12 weeks. Single Leg-Stance-Eyes Open (SLS-EO), Single Leg-Stance Eyes Closed (SLS-EC), computerized balance measurements, the Timed Up and Go (TUG) test, Berg Balance Scale (BBS), the Survey of Activities and Fear of Falling in the elderly (SAFFE), the Geriatric Depression Scale (GDS), and the Beck Depression Scale (BDS) were assessed before and after the final training session. RESULTS: Both exercise groups yielded better results in dynamic balance assessments (TUG and BBS) at the 12th week (p< 0.05). Group 1 also showed significant improvements in the measurements of SLS-EO, SLS-EC, SAFFE, GDS, and BDS during the post-intervention period (all p< 0.05). When the groups were compared, a significant difference was found between groups in favor of Group 1 in terms of the SLS-EO and SAFFE (p< 0.05). CONCLUSIONS: It can be concluded that Tai Chi may be a more successful exercise intervention for factors-related to falls in older people.
