Methods: Preterm infants with gestational age (GA) of <37 weeks who had ingui nal herniorrhaphy before the age of 6 months were enrolled. Early repair was defined as undergoing herniorrhaphy before discharge from the neonatal intensive care unit (NICU), and late repair was defined as undergoing herniorrhaphy as an outpatient after discharge from the NICU. Results: The incidence rates of preoperative incarceration and recurrence were not significantly different between the two groups. Postoperative apnea and mechanical ventilation were more frequent in the early-repair group than in the late-repair group. Postoperative apnea was more frequent in the early-repair group after adjustments for GA and birth weight. However, no significant difference in postoperative mechanical ventilation was found between the two groups after adjustments for GA and birth weight. The incidence of postoperative apnea was associated with small weight at repair, early repair, general anesthesia, younger GA, small weight at birth, and bronchopul monary dysplasia. Contralateral metachronous hernia was most frequent in infants with small weight at repair, early repair, very low birth weight (VLBW), male sex, and right-sided hernia. Conclusion: Late repair was safe and did not increase the risk of incarceration or recurrence, but decreased the risks of postoperative apnea and metachronous hernia. Regional anesthesia could reduce the risk of postoperative apnea. Male infants born with VLBWs and right-sided hernia should be followed up carefully for metachronous hernia.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"118-125"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48246019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to evaluate mortality and morbidities according to the time of PDA closure. Methods: For this study, 117 preterm infants with gestational age (GA) of <30 weeks who had PDA were enrolled and allocated to two groups according to the time of PDA closure as follows: early closed group (n=40, PDA closure in <14 days after birth) and delayed closed group (n=77, PDA closure in ≥14 days after birth). Results: GA was higher in the early closed group than in the delayed closed group (27.2±1.6 weeks vs. 26.3±1.7 weeks, P=0.005). Other demographic factors, such as birth weight, Apgar score, and maternal status were not significantly different between the two groups. The incidence rates of surfactant redosing, retinopathy of prematurity (stage ≥II), necrotizing enterocolitis (stage ≥II), moderate to severe bronchopulmo nary dysplasia, and mortality were similar between the two groups. The total durations of mechanical ventilation, invasive ventilation, and hospital stay were longer in the delayed closed group than in the early closed group. However, these became similar after adjustment for GA. The incidence rate of intraventricular hemorrhage (grade ≥III) was significantly higher in the early closed group than in the delayed closed group after adjustment for GA (25.0% vs. 13.0%, adjusted P for GA=0.021). Conclusion: In this study, delayed PDA closure was safe, as it did not increase mortality and morbidity rates.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"111-117"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42209001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We reviewed the medical records of 22 preterm infants who were born <30 weeks of gestational age with birth weight <1,500 g, diagnosed with early PH, and treated with iNO within the first 72 hours after birth. Responders were defined by a reduction in FiO2 >20% and/or oxygenation index (OI) >20% from the baseline values at 1 hour after beginning iNO therapy. Cardiorespiratory support indices including OI, oxygen saturation index, and vasoactive-inotropic score (VIS) were serially obtained for 96 hours following iNO therapy. Results: The mean gestational age of the patients was 26.1±2.0 weeks and the mean birth weight was 842±298 g. The mean OI at the start of iNO was 63.8±61.0. Improvement in oxygenation indicated by prompt decrease in FiO2 and OI from the baseline values were observed 1 hour after beginning iNO therapy and lasted up to 96 hours. After iNO therapy, VIS increased until 24 hours and decreased thereafter. At 1 hour after iNO, 16 patients (73%) were classified as responders and six (27%) as nonresponders. Compared with nonresponders, responders did not demonstrate the beneficial effect of iNO in terms of short-term survival and neonatal complications. The 1-year mortality rate did not differ between responders (56%) and nonresponders (67%). Conclusion: Although iNO treatment immediately improved oxygenation in most VLBW infants with early severe PH, the long-term mortality rate was high. A largescale study is needed to determine whether the initial response to iNO can predict patients’ survival.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"133-140"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48203569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This disorder is a genodermatosis with characteristic cutaneous lesions and manifestations affecting the eyes, teeth, hair, and central nervous system. Genodermatosis is a hereditary disease caused by mutations in the nuclear factor-kappa B essential modulator gene mapped to chromosome Xq28. This gene encodes a variety of cytokines and chemokine regulators and is indispensable for protecting cells from tumor necrosis factor-induced apoptosis. Here we describe a case of male newborn with vesiculobullous cutaneous lesions over the left thigh and leg. We first considered the cutaneous lesions a skin infection, as they improved with intravenous antibiotics. However, recurrence and the need for repeated hospitalizations made us consider the differential diagnosis of IP, for which we performed a skin biopsy and chromosome analysis. The histology results were compatible with IP, that is, eosinophilic infiltration in the dermis and epidermis, and individual cell dyskeratinization. The chromosome analysis result was a normal 46, XY karyotype. Here we report the case of a male newborn with IP that manifested as multiple vesiculobullous skin lesions and was initially misdiagnosed as a recurrent skin infection.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"141-146"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48067094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We analyzed the medical records of 352 preterm infants born at 23 to 32 weeks’ gestational age (GA) who underwent both automated auditory brainstem response (aABR) and confirmatory ABR (cABR). Results: Mean GA, mean birth weight, the incidence of small for GA and cesarean section birth were significantly different between the pass and refer groups on aABR and the normal and abnormal groups of cABR. On univariate analysis, bronchopul monary dysplasia (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.00 to 7.48), intraventricular hemorrhage (OR, 7.02; 95% CI, 1.59 to 31.05), and use of furosemide (OR, 3.84; 95% CI, 1.38 to 10.73) were the factors related to refer results on aABR. Peri ventricular leukomalacia (PVL; OR, 4.00; 95% CI, 1.39 to 11.52) and use of vancomycin (OR, 2.86; 95% CI, 1.22 to 6.73) were associated with abnormal cABR. Twentyfive (7.9%) infants had discrepant aABR and cABR results, particularly males and those in whom vancomycin was used. Conclusion: PVL and use of vancomycin were confirmed as independent risk factors for hearing loss in infants born at less than 32 weeks’ GA. Also, discrepancies between the screening and confirmatory test may occur, especially among male infants and those in whom vancomycin was used. The hearing of infants must be assessed more carefully in such groups regardless of NHS results.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"126-132"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48871864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One protocol used chloral hydrate (CH) with monitoring conducted by non-anesthesiologists, and the other used a continuous infusion of propofol (PF) with monitoring by anesthesiologists. Methods: A total of 250 preterm infants born between January 2011 and December 2015 who received brain MRI during hospitalization in our neonatal intensive care unit (NICU) were included in this retrospective study. In period 1, sedation for brain MRI was done using a single dose or multiple doses of CH with monitoring conducted by NICU medical staff. In period 2, an anesthesiologist prescribed a continuous infu sion of PF and titrated the dosage for minimal and adequate sedation. Data on the adverse events, including desaturation and bradycardia, were collected and compared between periods 1 and 2. Results: Despite similar gestational ages of the patients in periods 1 and 2, the infants in period 1 showed a higher risk of developing bradycardia after sedation compared to those in period 2 (30.2% vs. 14.8%; an adjusted odds ratio of 2.35; 95% confidence interval of 1.12 to 4.91). Infants who had an adverse event after sedation had a lower gestational age and corrected age at the time of MRI (26.8 weeks vs. 27.9 weeks, P=0.004; 37.3 weeks vs. 38.3 weeks, P=0.023). The duration of MRI was significantly longer in infants that had an adverse event than those that did not (70.9 minutes vs. 64.3 minutes). After adju sting for various clinical factors, lower gestational age, lower corrected age at the time of MRI, and period 1 increased the risk of developing adverse events after sedation for MRI. Conclusion: The use of a continuous PF infusion with dose titration and monitoring by an anesthesiologist is safe and feasible as a sedation protocol for brain MRI in prematurely born infants.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"105-110"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48972442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We performed a retrospective medical chart review for 75 premature in fants who were born at a gestational age (GA) of ≤34 weeks (between January 2017 and December 2019) and developed RDS after birth. Data on the demographic and outcome variables, including respiratory outcomes, were collected and compared between the infants who received LISA and those who received INSURE as a rescue therapy for RDS. Results: No signifcant differences in GA, birth weight, and other demographic characteristics were found between the LISA and INSURE groups (GA: 28.7 weeks vs. 28.8 weeks, P=0.449; birth weight: 1,236 g vs. 1,124 g, P=0.714). At the delivery room, although the infants showed no significant difference in positive pressure ventilation rate after birth, the LISA group showed a higher rate of continuous positive airway pressure application than the INSURE group. The infants in the LISA group presented a higher risk of requiring multiple doses of surfactant for RDS than the infants in the INSURE group (57% vs. 17.5%, P=0.001). However, the duration of invasive and/ or noninvasive respiratory support and incidence of bronchopulmonary dysplasia showed no signifciant difference between the two groups. Conclusion: In the present study, no significant differences in the incidence of in hospital respiratory outcomes such as bronchopulmonary dysplasia were found between the LISA and INSURE groups. These results suggest that LISA can be an alternative therapeutic option for treating RDS to avoid intubation and mechanical ventilation in premature infants.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"27 1","pages":"99-104"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45982276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
