Left untreated, it can lead to long-term neurosensory and psychoaffective consequences. In Cameroon, this subject has been scarcely explored, thus constituting an impediment to the management of care-induced pain. Objective: Assess procedural pain in neonates in Yaoundé. Material and Methods: We conducted a cross sectional study with prospective data collection over a period of eight months (October 2022 to May 2023) in three hospitals. We included neonates who were being cared for and were not crying prior to the onset of healthcare, whose parents consented to the study. Assessments were done using the DAN scale, which is specific to care-induced pain. Data was entered and analyzed using SPSS 23.0 software. Results: A total of 161 newborns were included. The hospital prevalence of care-induced pain in neonates was 85%. Neonatal sepsis was the main cause for admission (96.6%). The most common procedures were venous blood sampling (94.4%) and insertion of peripheral venous lines (93.8%). The pain intensity for these procedures was severe (83.9%). The most painful procedure was lumbar tap, followed by venous access procedures. Conclusion: Neonates in hospitals are subjected to many painful procedures. The pain experienced during these procedures is severe. The most nociceptive procedure is a lumbar puncture.展开更多

The aim of this study was to describe the epidemiology, the diagnostic, and the outcomes of neonatal respiratory distress. Methods: This was a cross-sectional study carried out in the pediatric wards of Lomé Teaching Hospitals (CHU Sylvanus Olympio and CHU Campus), including neonates treated for respiratory distress (dyspnea associated with the use of accessory muscles of respiration, noisy breathing and with or without cyanosis) from January 1, 2021 to December 31, 2021. Data were entered using Epi Data 3.1 and SPSS software version 12.0. Results: The total number of neonates hospitalized for respiratory distress was 353, with a frequency of 12.5% and a sex ratio of 1.5. The mean age was 0.82 ± 3.20 days;the 0 - 6-day age group accounted for 92.4% of cases. Neonates had been resuscitated at birth in 46.7% of cases. Dyspnea was tachypnea in 94% of cases and bradypnea in 6%. Dyspnea was associated with cyanosis in 21.5% of cases. The severity of the respiratory distress was moderate in 64.9% of cases. Perinatal asphyxia (49.1%), inhalation pneumonitis (17.1%) and neonatal bacterial infection (14.1%) were the main etiologies. The mortality rate was 20.4%. Age greater than or equal to seven days, no neonatal resuscitation were protective factors against death. Prematurity, no antenatal consultations follow up, neonatal resuscitation, severe respiratory distress were risk factors of death. Conclusion: Neonatal respiratory distress was common in the early neonatal period and its mortality was high.展开更多

Many studies have reported that the incidence of SOAEs in adults is less than 50%. Therefore, measurement of SOAEs may be of little value to clinical examinations. However, the incidence of SOAEs in infants and neonates is higher than in adults. OBJECTIVE: To analyze the basic characteristics of SOAEs in 2–4 day old neonates, and to demonstrate the difference in OHC function between sexes and ears. DESIGN, TIME AND SETTING: Neurophysiological contrast study, performed in the Department of Neonates, Beijing Chaoyang Hospital, Capital Medical University, between December 2007 and August 2008. PARTICIPANTS: A total of 112 newborns (224 ears) consisting of 59 females and 53 males were included in this study. METHODS: The probe was adapted and embedded in the neonate external auditory canal with a foam rubber earplug after checking and clearing up the outer ear canal. The presence of SOAEs was determined when the signal amplitude had a clear peak exceeding –30 dB, or was 3 dB above the noise floor. MAIN OUTCOME MEASURES: The incidence of SOAEs, the number of SOAE signal peaks, and the maximal tension of SOAEs. RESULTS: The incidence in females (79.7%) was higher than males (76.4%) (P 〉 0.05), and the incidence in right ears (86.6%) was higher than in left ears (69.6%) (P 〈 0.05). There were no significant difference in the number of SOAE peaks between females and males (4.49 vs. 4.28), or between right ears and left ears (4.62 vs. 4.12) (P 〉 0.05). The mean maximum SOAE level per ear in females (–3.29 ± 9.28) dB sound pressure level (SPL) was slightly higher than that in males (–3.91 ± 9.14) dB SPL (P 〉 0.05). Also, the mean maximum SOAE level in right ears (–2.03 ± 9.11) dB SPL was higher than in left ears (–5.50 ± 9.65) dB SPL (P 〈 0.05). The maximum SOAE level showed a positive correlation with maximum SOAE number in emitting ears (r = 0.55, P 〈 0.01). CONCLUSION: The incidence of SOAEs in neonates is high (78.1%) within 4 days of birth. The in-cidence of SOAEs and the maximum SOAE level exhibited a significant difference between right and left ears, but the difference between sexes was insignificant. Both the strongest SOAE signal peak and number of SOAEs per ear are representative of the function OHCs.展开更多

Computed...With improvements in care of at-risk neonates, more and more children survive. This makes it increasingly important to assess, soon after birth, the prognosis of children with hypoxic-ischemic encephalopathy. Computed tomography, ultrasound, and conventional magnetic resonance imaging are helpful to diagnose brain injury, but cannot quantify white matter damage. In this study, ten full-term infants without brain injury and twenty-two full-term neonates with hypoxic-ischemic encephalopathy (14 moderate cases and 8 severe cases) underwent diffusion tensor imaging to assess its feasibility in evaluating white matter damage in this condition. Results demonstrated that fractional anisotropy, voxel volume, and number of fiber bundles were different in some brain areas between infants with brain injury and those without brain injury. The correlation between fractional anisotropy values and neonatal behavioral neurological assessment scores was closest in the posterior limbs of the internal capsule. We conclude that diffusion tensor imaging can quantify white matter injury in neonates with hypoxic-ischemic encephalopathy.展开更多

A total of 168 neonates were divided into the hyperbilirubinemia group(case group, n=108) and healthy neonates group(control group, n=60). Their DNA was obtained through blood extraction. The gene exon mutation of UGT1A1 was detected by Sanger sequencing, which revealed the relationship between UGT1A1*28 and Gly71 Arg polymorphism with neonatal hyperbilirubinemia of neonates. The results showed that:(1) The frequency of UGT1A1*28 allele mutation in the case group and the control group was 9.3% and 10% respectively, with the difference being not significant between the two groups(P〉0.05).(2) The frequency of Gly71 Arg allele mutation in the case group and the control group was 35.1% and 21.7% respectively, with the difference being significant between the two groups(P〈0.01).(3) The serum bilirubin level of Gly71 Arg mutant homozygous and heterozygous subgroups(n=66) in the case group was 302.7±31.4 μmol/L, which was significantly higher than 267.3±28.5 μmol/L of the wild subgroup(n=42)(P〈0.01). It was suggested that the occurrence of neonatal hyperbilirubinemia of neonates in Wuhan was not associated with UGT1A1*28 gene polymorphism, but closely with the Gly71 Arg gene polymorphism. Meanwhile, the Arg allele mutation was related to the degree of jaundice.展开更多

CHB is defined as conjugated bilirubin(CB) fraction greater than 15% of total bilirubin and CB greater or equal to 25 μmol/L. ECHB is defined as CHB detected within 14 d of life. "Late-onset" CHB(LCHB) is detected at 15-28 d of life and served as the comparison group.RESULTS Total of 117 patients were recruited: 65 had ECHB, 52had LCHB. Neonates with ECHB were more likely to be clinically unwell(80.0% vs 42.3%, P < 0.001) and associated with non-hepatic causes(73.8% vs 44.2%, P = 0.001) compared to LCHB. Multifactorial liver injury(75.0%) and sepsis(17.3%) were the most common causes of ECHB in clinically unwell infants, majority(87.5%) had resolution of CHB with no progression to chronic liver disease. Inborn errors of metabolism were rare(5.8%) but associated with high mortality(100%) in our series. In the subgroup of clinically well infants(n = 13) with ECHB, biliary atresia(BA) was the most common diagnosis(61.5%), all presented initially with normal stools and decline in total bilirubin but with persistent CHB. CONCLUSION Secondary hepatic injury is the most common reason for ECHB. BA presents with ECHB in well infants without classical symptoms of pale stools and deep jaundice.展开更多

Neuropathologic studies have demonstrated brainstem involvement in severely asphyxiated infants as an indicator of poor outcome. Among survivors to HIE, the most frequent clinical complaints that may be predicted by brainstem lesions include feeding problems, speech, language and communication problems and visual impairments. Clinical series, including vascular and metabolic etiologies, have found selective involvement of the brainstem with the demonstration of symmetric bilateral columnar lesions of the tegmentum. The role of brainstem lesions in HIE is currently a matter of debate, especially when tegmental lesions are present in the absence of supratentorial lesions. Differential diagnosis of tegmental lesions in neonates and infants include congenital metabolic syndromes and drug-related processes. Brainstem injury with the presence of supratentorial lesions is a predictor of poor outcome and high rates of mortality and morbidity. Further investigation will be conducted to identify specific sites of the brainstem that are vulnerable to hypoxic-ischemic and toxic-metabolic insults.展开更多

The treatments consisted of indomethacin[0.2 mg/(kg$d), 3-day cycle], ibuprofen [10 mg/(kg$d) followed by 5 mg/(kg$d), 3-day cycle], and paracetamol(15 mg/kg every 6 h, 5-day cycle). The drugs were administered as an oral solution. The following variables were considered: gestational age,newborn weight at birth, Apgar score, diuresis, serum creatinine and urea levels, and serum electrolyte levels(sodium and potassium).Results: Treatment with indomethacin presented efficacy of 87.5% in closure of the ductus with a mean outcome period of 3.5 d. In premature neonates with CHRs and contraindications for indomethacin, the initial treatment with either ibuprofen or paracetamol failed to close the ductus. However, when this treatment was followed by indomethacin, closure occurred in 66.7% of the neonates, with an outcome period of9.66 d. The initial treatment with one cycle of ibuprofen followed by one or two cycles of paracetamol failed to close the ductus.Conclusions: Oral indomethacin was effective for closure of the PDA in premature neonates with severe CHRs. Oral paracetamol or ibuprofen for PDA closure in premature neonates with severe CHRs and contraindications for indomethacin was ineffective.However, results in clinical improvements of neonates allowed the subsequent use of indomethacin and successful closure of the ductus. A significant reduction of diuresis occurred in neonates who were treated with indomethacin, either as a first-line treatment or after the failure of ibuprofen or paracetamol.展开更多

However, the specific brain networks implicated in neonatal cases remain poorly understood. In this study, we recruited 14 termborn infants with mild hypoxic ischemic encephalopathy and 14 term-born infants with severe hypoxic ischemic encephalopathy from Changzhou Children's Hospital, China. Resting-state functional magnetic resonance imaging data showed efficient small-world organization in whole-brain networks in both the mild and severe hypoxic ischemic encephalopathy groups. However, compared with the mild hypoxic ischemic encephalopathy group, the severe hypoxic ischemic encephalopathy group exhibited decreased local efficiency and a low clustering coefficient. The distribution of hub regions in the functional networks had fewer nodes in the severe hypoxic ischemic encephalopathy group compared with the mild hypoxic ischemic encephalopathy group. Moreover, nodal efficiency was reduced in the left rolandic operculum, left supramarginal gyrus, bilateral superior temporal gyrus, and right middle temporal gyrus. These results suggest that the topological structure of the resting state functional network in children with severe hypoxic ischemic encephalopathy is clearly distinct from that in children with mild hypoxic ischemic encephalopathy, and may be associated with impaired language, motion, and cognition. These data indicate that it may be possible to make early predictions regarding brain development in children with severe hypoxic ischemic encephalopathy, enabling early interventions targeting brain function. This study was approved by the Regional Ethics Review Boards of the Changzhou Children's Hospital(approval No. 2013-001) on January 31, 2013. Informed consent was obtained from the family members of the children. The trial was registered with the Chinese Clinical Trial Registry(registration number: ChiCTR1800016409) and the protocol version is 1.0.展开更多

Methods: Secondary analysis of data from case reports published in scientific literature indexed in Medline, Scopus and LILACS databases, and starting from the year, full texts were registered until the year 2010. Results: Thirty-four species of fungi were isolated in 252 cases reported over a 40-year period. The distribution of fungal groups according to the development level of a case’s region of origin was very uneven (p Aspergillus sp.) in more developed countries. However, 73% of the chi-squared distribution corresponded to differences observed in the frequency of Candida sp. and non-albicans Candida. While the frequency of candidemia by C. albicans was progressively declining in the period from 1966 to 2010, reports of non-albicans candidemia and other non-Candida fungi became significantly (p albicans Candida or non-Candida fungi were isolated. Conclusion: fungi of the genera Candida and Aspergillus were the etiologic agents most frequently identified in published cases of neonatal fungemia;the outcome of death was more often related to cases where non-albicans Candida or non-Candida fungi were isolated.展开更多

文摘Background:The optimal surgical timing and clinical outcomes of ventricular septal defect(VSD)closure in neo-nates remain unclear.We aimed to evaluate the clinical outcomes of VSD closure in neonates(age≤30 days).Methods:We retrospectively reviewed 50 consecutive neonates who underwent VSD closure for isolated VSDs between August 2003 and June 2021.Indications for the procedure included congestive heart failure/failure to thrive and pulmonary hypertension.Major adverse events(MAEs)were defined as the composite of all-cause mortality,reoperation,persistent atrioventricular block,and significant(≥grade 2)valvular dysfunction.Results:The median age and body weight at operation were 26.0 days(interquartile range[IQR],18.8–28.3)and 3.7 kg(IQR,3.3–4.2),respectively.The median follow-up duration was 110.4 months(IQR,56.8–165.0).Seven patients required preoperative respiratory support,andfive had significant(≥grade 2)preoperative valvular dysfunction.One early mortality occurred due to irreversible cardiogenic shock;no late mortality was observed.One reopera-tion was due to hemodynamically significant residual VSD at 103.8 months postoperatively.The overall survival,freedom from reoperation,and freedom from MAE at 15-years were 98.0%,96.3%,and 94.4%,respectively.Pre-operative mechanical ventilation was associated with a longer duration of postoperative mechanical ventilation(p<0.001)and a longer length of intensive care unit stay(p<0.001).Conclusions:VSD closure with favorable outcomes without morbidities is feasible even in neonates.However,neonates requiring preoperative respiratory support may require careful postoperative management considering the long-term postoperative risks.Overall,surgical VSD closure might be indicated earlier in neonates with respiratory compromise.
文摘Objective:To evaluate the impact of the severe COVID-19 pandemic on neonates and develop strategies to improve their outcomes.Methods:We conducted an observational cross-sectional study at Children's Hospital 1(CH1)from July 25,2021,to May 31,2022.All neonates who had fever or respiratory symptoms or were born from mothers with COVID-19 and had a positive RT-PCR SARS-CoV-2 result would be included.We classified neonates with COVID-19 into 2 groups:mild/moderate and severe for analysis.Differences between groups were analyzed using Fisher's exact test/Chi-square test for categorical variables and Student's t-test/Wilcoxon Rank Sum test for continuous variables.Results:This study included 88 newborns who had positive RT-PCR SARS-CoV-2 results.The severity COVID-19 rate among neonatal cases was found to be 13.6%(12/88),with a corresponding mortality rate of 1.1%(1/88).All severe cases showed lung abnormalities as evident on chest X-ray images.In addition to respiratory symptoms,a higher incidence of gastrointestinal manifestations,such as vomiting and diarrhea,was observed in the severe group,indicating a compelling association.The administration of anticoagulant and anti-inflammatory drugs in the study group resulted in a satisfactory outcome with no significant complications.Conclusions:The COVID-19 pandemic has had a substantial impact on the well-being of neonates.The management of COVID-19 in this population presents significant challenges.
文摘AIM:To explore the relationship between retinal exudative changes in neonates and perinatal toxoplasmosis,others,rubella,cytomegalovirus,and herpes simplex virus(TORCH)infections,as well as the characteristics of TORCH infection in neonates with retinal exudative changes.METHODS:Retrospective study.A total of 612 neonates with retinal exudative changes detected during ophthalmic screening in our hospital from May 2019 to March 2023 were selected.TORCH tests were performed on these neonates,and the results were subjected to statistical analysis to determine the infection characteristics.The neonates with retinal exudative changes were grouped by sex and age,the characteristics of TORCH infection were analyzed,and the positive rates were compared.RESULTS:Among the 612 neonates with retinal exudative changes,the highest positive rate was observed for cytomegalovirus(CMV-IgG)(96.7%),followed by rubella virus(RV-IgG)(73.9%).Mixed infections with two or three viruses were also observed,with the highest positive rate for mixed infection of RV-IgG and CMV-IgG reaching 71.2%.There was no statistically significant difference in TORCH infection among neonates of different sex(P>0.05).However,there were statistically significant differences in RV-IgG and CMV-IgM infections with retinal exudative changes among neonates of different age groups(P<0.05).CONCLUSION:Perinatal TORCH infection may be an important factor causing retinal exudative changes in neonates.The differences in various infections are not related to sex but are related to different age groups.
文摘Introduction: Acute pain associated with caregiving is a major cause of pain among neonates. Left untreated, it can lead to long-term neurosensory and psychoaffective consequences. In Cameroon, this subject has been scarcely explored, thus constituting an impediment to the management of care-induced pain. Objective: Assess procedural pain in neonates in Yaoundé. Material and Methods: We conducted a cross sectional study with prospective data collection over a period of eight months (October 2022 to May 2023) in three hospitals. We included neonates who were being cared for and were not crying prior to the onset of healthcare, whose parents consented to the study. Assessments were done using the DAN scale, which is specific to care-induced pain. Data was entered and analyzed using SPSS 23.0 software. Results: A total of 161 newborns were included. The hospital prevalence of care-induced pain in neonates was 85%. Neonatal sepsis was the main cause for admission (96.6%). The most common procedures were venous blood sampling (94.4%) and insertion of peripheral venous lines (93.8%). The pain intensity for these procedures was severe (83.9%). The most painful procedure was lumbar tap, followed by venous access procedures. Conclusion: Neonates in hospitals are subjected to many painful procedures. The pain experienced during these procedures is severe. The most nociceptive procedure is a lumbar puncture.
文摘Introduction: Respiratory distress in neonates is a neonatal emergency that can lead to serious complications if not treated appropriately. The aim of this study was to describe the epidemiology, the diagnostic, and the outcomes of neonatal respiratory distress. Methods: This was a cross-sectional study carried out in the pediatric wards of Lomé Teaching Hospitals (CHU Sylvanus Olympio and CHU Campus), including neonates treated for respiratory distress (dyspnea associated with the use of accessory muscles of respiration, noisy breathing and with or without cyanosis) from January 1, 2021 to December 31, 2021. Data were entered using Epi Data 3.1 and SPSS software version 12.0. Results: The total number of neonates hospitalized for respiratory distress was 353, with a frequency of 12.5% and a sex ratio of 1.5. The mean age was 0.82 ± 3.20 days;the 0 - 6-day age group accounted for 92.4% of cases. Neonates had been resuscitated at birth in 46.7% of cases. Dyspnea was tachypnea in 94% of cases and bradypnea in 6%. Dyspnea was associated with cyanosis in 21.5% of cases. The severity of the respiratory distress was moderate in 64.9% of cases. Perinatal asphyxia (49.1%), inhalation pneumonitis (17.1%) and neonatal bacterial infection (14.1%) were the main etiologies. The mortality rate was 20.4%. Age greater than or equal to seven days, no neonatal resuscitation were protective factors against death. Prematurity, no antenatal consultations follow up, neonatal resuscitation, severe respiratory distress were risk factors of death. Conclusion: Neonatal respiratory distress was common in the early neonatal period and its mortality was high.
文摘Neonates,especially admitted to neonatal intensive care unit,frequently need various medical interventions in their early days.A common procedure is the heel prick for blood sampling.Although necessary for diagnosis,this procedure can be stressful for neonates,causing pain,extended crying,and discomfort.Reducing distress in neonates during such procedures is important for the well‐being of neonates and the satisfaction of caregivers and healthcare providers.Therefore,this review aims to identify and compare the efficacy of 25%dextrose and breast milk on pain and duration of cry among neonates during heel-lance.As part of its review process,the article examined widely used databases,including PubMed,EMBASE,Cochrane,Academia,and Google Scholar.For the meta-analysis,the authors utilized RevMan 5.4.All eligible trials were analyzed using the Cochrane Risk of Bias Tool to assess the quality of the included studies and evaluate the risk of bias.Out of 131 studies reviewed,seven studies were included in meta-analysis of pain,and four studies were included in duration of cry.The results show that 25%dextrose is more effective to reduce pain among neonates during minor invasive procedure like heel prick(P<0.00001),whereas both interventions are effective in the reduction of crying duration.This review highlights that dextrose is more effective in reducing pain in comparison to breast milk.However,additional well-designed studies with larger sample sizes and extended follow-up periods are needed to validate and build upon the current findings.Hence,this review underscores the importance of utilizing effective pain management strategies,such as 25%dextrose,to enhance neonatal care and improve the overall well-being of newborns during invasive procedures.
文摘Objective:To investigate the clinical profile and risk factors of symptomatic and asymptomatic hypoglycemia in neonates admitted to a neonatal intensive care unit in a tertiary care center.Methods:The prospective observational study was conducted in a tertiary care center in the Specialty Department of Pediatric.196 Newborn babies with blood glucose levels<45 mg/dL were examined with a simple random sampling method between December 2019 and November 2021.Maternal and neonatal risk factors and clinical signs were recorded and compared between symptomatic and asymptomatic cases.Results:The proportion of symptomatic hypoglycemia neonates born to gestational diabetes mellitus mothers was significantly higher(23.4%vs.8.4%)(P<0.05).Small for gestational age,low birth weight,respiratory distress syndrome,hypothermia,and endocrine disorders were risk factors.The death rate in asymptomatic hypoglycemia neonates was significantly higher(58%vs.39%)(P<0.05).Conclusions:The study indicates that maternal gestational diabetes mellitus is associated with symptomatic hypoglycemia and asymptomatic hypoglycemia is associated with neonatal mortality.It is important to take vigilance and timely interventions to address associated symptoms,particularly poor feeding,in the management of neonatal hypoglycemia.
文摘BACKGROUND Neonatal respiratory distress syndrome(NRDS)is one of the most common diseases in neonatal intensive care units,with an incidence rate of about 7%among infants.Additionally,it is a leading cause of neonatal death in hospitals in China.The main mechanism of the disease is hypoxemia and hypercapnia caused by lack of surfactant AIM To explore the effect of pulmonary surfactant(PS)combined with noninvasive positive pressure ventilation on keratin-14(KRT-14)and endothelin-1(ET-1)levels in peripheral blood and the effectiveness in treating NRDS.METHODS Altogether 137 neonates with respiratory distress syndrome treated in our hospital from April 2019 to July 2021 were included.Of these,64 control cases were treated with noninvasive positive pressure ventilation and 73 observation cases were treated with PS combined with noninvasive positive pressure ventilation.The expression of KRT-14 and ET-1 in the two groups was compared.The deaths,complications,and PaO_(2),PaCO_(2),and PaO_(2)/FiO_(2)blood gas indexes in the two groups were compared.Receiver operating characteristic curve(ROC)analysis was used to determine the diagnostic value of KRT-14 and ET-1 in the treatment of NRDS.RESULTS The observation group had a significantly higher effectiveness rate than the control group.There was no significant difference between the two groups in terms of neonatal mortality and adverse reactions,such as bronchial dysplasia,cyanosis,and shortness of breath.After treatment,the levels of PaO_(2)and PaO_(2)/FiO_(2)in both groups were significantly higher than before treatment,while the level of PaCO_(2)was significantly lower.After treatment,the observation group had significantly higher levels of PaO_(2)and PaO_(2)/FiO_(2)than the control group,while PaCO_(2)was notably lower in the observation group.After treatment,the KRT-14 and ET-1 levels in both groups were significantly decreased compared with the pre-treatment levels.The observation group had a reduction of KRT-14 and ET-1 levels than the control group.ROC curve analysis showed that the area under the curve(AUC)of KRT-14 was 0.791,and the AUC of ET-1 was 0.816.CONCLUSION Combining PS with noninvasive positive pressure ventilation significantly improved the effectiveness of NRDS therapy.KRT-14 and ET-1 levels may have potential as therapeutic and diagnostic indicators.

文摘Neonatal hypoxic-ischemic encephalopathy(HIE)is a significant cause of disability in children.Improving brain function and accelerating neurological recovery may require a combination of neuroprotective and pro-regenerative treatments at different stages of HIE.While the first hours after the neonatal insult are the most critical period for neuroprotection,the existence of secondary and tertiary mechanisms of brain injury offers the possibility of preventing delayed neurodegeneration in the subsequent days,weeks,or months(Levison et al.,2022).

文摘Moderate to severe perinatal hypoxic-ischemic encephalopathy occurs in~1 to 3/1000 live births in high-income countries and is associated with a significant risk of death or neurodevelopmental disability.Detailed assessment is important to help identify highrisk infants,to help families,and to support appropriate interventions.A wide range of monitoring tools is available to assess changes over time,including urine and blood biomarkers,neurological examination,and electroencephalography.At present,magnetic resonance imaging is unique as although it is expensive and not suited to monitoring the early evolution of hypoxic-ischemic encephalopathy by a week of life it can provide direct insight into the anatomical changes in the brain after hypoxic-ischemic encephalopathy and so offers strong prognostic information on the long-term outcome after hypoxic-ischemic encephalopathy.This review investigated the temporal dynamics of neonatal hypoxic-ischemic encephalopathy injuries,with a particular emphasis on exploring the correlation between the prognostic implications of magnetic resonance imaging scans in the first week of life and their relationship to long-term outcome prediction,particularly for infants treated with therapeutic hypothermia.A comprehensive literature search,from 2016 to 2024,identified 20 pertinent articles.This review highlights that while the optimal timing of magnetic resonance imaging scans is not clear,overall,it suggests that magnetic resonance imaging within the first week of life provides strong prognostic accuracy.Many challenges limit the timing consistency,particularly the need for intensive care and clinical monitoring.Conversely,although most reports examined the prognostic value of scans taken between 4 and 10 days after birth,there is evidence from small numbers of cases that,at times,brain injury may continue to evolve for weeks after birth.This suggests that in the future it will be important to explore a wider range of times after hypoxic-ischemic encephalopathy to fully understand the optimal timing for predicting long-term outcomes.

文摘BACKGROUND: Spontaneous otoacoustic emissions (SOAEs) are regarded as a valuable audio- metric parameter that objectively reflects the function of outer hair cells (OHCs). Many studies have reported that the incidence of SOAEs in adults is less than 50%. Therefore, measurement of SOAEs may be of little value to clinical examinations. However, the incidence of SOAEs in infants and neonates is higher than in adults. OBJECTIVE: To analyze the basic characteristics of SOAEs in 2–4 day old neonates, and to demonstrate the difference in OHC function between sexes and ears. DESIGN, TIME AND SETTING: Neurophysiological contrast study, performed in the Department of Neonates, Beijing Chaoyang Hospital, Capital Medical University, between December 2007 and August 2008. PARTICIPANTS: A total of 112 newborns (224 ears) consisting of 59 females and 53 males were included in this study. METHODS: The probe was adapted and embedded in the neonate external auditory canal with a foam rubber earplug after checking and clearing up the outer ear canal. The presence of SOAEs was determined when the signal amplitude had a clear peak exceeding –30 dB, or was 3 dB above the noise floor. MAIN OUTCOME MEASURES: The incidence of SOAEs, the number of SOAE signal peaks, and the maximal tension of SOAEs. RESULTS: The incidence in females (79.7%) was higher than males (76.4%) (P 〉 0.05), and the incidence in right ears (86.6%) was higher than in left ears (69.6%) (P 〈 0.05). There were no significant difference in the number of SOAE peaks between females and males (4.49 vs. 4.28), or between right ears and left ears (4.62 vs. 4.12) (P 〉 0.05). The mean maximum SOAE level per ear in females (–3.29 ± 9.28) dB sound pressure level (SPL) was slightly higher than that in males (–3.91 ± 9.14) dB SPL (P 〉 0.05). Also, the mean maximum SOAE level in right ears (–2.03 ± 9.11) dB SPL was higher than in left ears (–5.50 ± 9.65) dB SPL (P 〈 0.05). The maximum SOAE level showed a positive correlation with maximum SOAE number in emitting ears (r = 0.55, P 〈 0.01). CONCLUSION: The incidence of SOAEs in neonates is high (78.1%) within 4 days of birth. The in-cidence of SOAEs and the maximum SOAE level exhibited a significant difference between right and left ears, but the difference between sexes was insignificant. Both the strongest SOAE signal peak and number of SOAEs per ear are representative of the function OHCs.

文摘With improvements in care of at-risk neonates, more and more children survive. This makes it increasingly important to assess, soon after birth, the prognosis of children with hypoxic-ischemic encephalopathy. Computed tomography, ultrasound, and conventional magnetic resonance imaging are helpful to diagnose brain injury, but cannot quantify white matter damage. In this study, ten full-term infants without brain injury and twenty-two full-term neonates with hypoxic-ischemic encephalopathy (14 moderate cases and 8 severe cases) underwent diffusion tensor imaging to assess its feasibility in evaluating white matter damage in this condition. Results demonstrated that fractional anisotropy, voxel volume, and number of fiber bundles were different in some brain areas between infants with brain injury and those without brain injury. The correlation between fractional anisotropy values and neonatal behavioral neurological assessment scores was closest in the posterior limbs of the internal capsule. We conclude that diffusion tensor imaging can quantify white matter injury in neonates with hypoxic-ischemic encephalopathy.

文摘This study attempts to discuss the correlation between UGT1A1*28 as uridine diphosphate glucuronosyltransferase gene promoter and coding region Gly71 Arg gene polymorphism with neonatal hyperbilirubinemia of neonates in Wuhan. A total of 168 neonates were divided into the hyperbilirubinemia group(case group, n=108) and healthy neonates group(control group, n=60). Their DNA was obtained through blood extraction. The gene exon mutation of UGT1A1 was detected by Sanger sequencing, which revealed the relationship between UGT1A1*28 and Gly71 Arg polymorphism with neonatal hyperbilirubinemia of neonates. The results showed that:(1) The frequency of UGT1A1*28 allele mutation in the case group and the control group was 9.3% and 10% respectively, with the difference being not significant between the two groups(P〉0.05).(2) The frequency of Gly71 Arg allele mutation in the case group and the control group was 35.1% and 21.7% respectively, with the difference being significant between the two groups(P〈0.01).(3) The serum bilirubin level of Gly71 Arg mutant homozygous and heterozygous subgroups(n=66) in the case group was 302.7±31.4 μmol/L, which was significantly higher than 267.3±28.5 μmol/L of the wild subgroup(n=42)(P〈0.01). It was suggested that the occurrence of neonatal hyperbilirubinemia of neonates in Wuhan was not associated with UGT1A1*28 gene polymorphism, but closely with the Gly71 Arg gene polymorphism. Meanwhile, the Arg allele mutation was related to the degree of jaundice.
文摘AIM To describe the etiology and characteristics of earlyonset conjugated hyperbilirubinemia(ECHB) presenting within 14 d of life in term neonates.METHODS Retrospective review was performed of term infants up to 28-d-old who presented with conjugated hyperbilirubinemia(CHB) at a tertiary center over a 5-year period from January 2010 to December 2014. CHB is defined as conjugated bilirubin(CB) fraction greater than 15% of total bilirubin and CB greater or equal to 25 μmol/L. ECHB is defined as CHB detected within 14 d of life. "Late-onset" CHB(LCHB) is detected at 15-28 d of life and served as the comparison group.RESULTS Total of 117 patients were recruited: 65 had ECHB, 52had LCHB. Neonates with ECHB were more likely to be clinically unwell(80.0% vs 42.3%, P < 0.001) and associated with non-hepatic causes(73.8% vs 44.2%, P = 0.001) compared to LCHB. Multifactorial liver injury(75.0%) and sepsis(17.3%) were the most common causes of ECHB in clinically unwell infants, majority(87.5%) had resolution of CHB with no progression to chronic liver disease. Inborn errors of metabolism were rare(5.8%) but associated with high mortality(100%) in our series. In the subgroup of clinically well infants(n = 13) with ECHB, biliary atresia(BA) was the most common diagnosis(61.5%), all presented initially with normal stools and decline in total bilirubin but with persistent CHB. CONCLUSION Secondary hepatic injury is the most common reason for ECHB. BA presents with ECHB in well infants without classical symptoms of pale stools and deep jaundice.
文摘Lesions of the brainstem have been reported in the clinical scenarios of hypoxic-ischemic encephalopathy(HIE), although the prevalence of these lesions is probably underestimated. Neuropathologic studies have demonstrated brainstem involvement in severely asphyxiated infants as an indicator of poor outcome. Among survivors to HIE, the most frequent clinical complaints that may be predicted by brainstem lesions include feeding problems, speech, language and communication problems and visual impairments. Clinical series, including vascular and metabolic etiologies, have found selective involvement of the brainstem with the demonstration of symmetric bilateral columnar lesions of the tegmentum. The role of brainstem lesions in HIE is currently a matter of debate, especially when tegmental lesions are present in the absence of supratentorial lesions. Differential diagnosis of tegmental lesions in neonates and infants include congenital metabolic syndromes and drug-related processes. Brainstem injury with the presence of supratentorial lesions is a predictor of poor outcome and high rates of mortality and morbidity. Further investigation will be conducted to identify specific sites of the brainstem that are vulnerable to hypoxic-ischemic and toxic-metabolic insults.

文摘Although hypothermia therapy is effective to treat neonatal hypoxic-ischemic encephalopathy,many neonatal patients die or suffer from severe neurological dysfunction.Erythropoietin is considered one of the most promising neuroprotective agents.We hypothesized that erythropoietin combined with hypothermia will improve efficacy of neonatal hypoxic-ischemic encephalopathy treatment.In this study,41 neonates with moderate/severe hypoxic-ischemic encephalopathy were randomly divided into a control group(hypothermia alone for 72 hours,n = 20) and erythropoietin group(hypothermia + erythropoietin 200 IU/kg for 10 days,n = 21).Our results show that compared with the control group,serum tau protein levels were lower and neonatal behavioral neurological assessment scores higher in the erythropoietin group at 8 and 12 days.However,neurodevelopmental outcome was similar between the two groups at 9 months of age.These findings suggest that erythropoietin combined with hypothermia reduces serum tau protein levels and improves neonatal behavioral neurology outcome but does not affect long-term neurodevelopmental outcome.
文摘Objective: To evaluate the efficacy of oral indomethacin, ibuprofen, and paracetamol in oral dosage form on patent ductus arteriosus(PDA) in premature neonates with significant clinical and hemodynamic repercussions(CHRs) and to determine the effect of these respective treatments on renal function.Methods: A retrospective study of cases of PDA in premature neonates in the Neonatal Intensive Care Unit was conducted. The treatments consisted of indomethacin[0.2 mg/(kg$d), 3-day cycle], ibuprofen [10 mg/(kg$d) followed by 5 mg/(kg$d), 3-day cycle], and paracetamol(15 mg/kg every 6 h, 5-day cycle). The drugs were administered as an oral solution. The following variables were considered: gestational age,newborn weight at birth, Apgar score, diuresis, serum creatinine and urea levels, and serum electrolyte levels(sodium and potassium).Results: Treatment with indomethacin presented efficacy of 87.5% in closure of the ductus with a mean outcome period of 3.5 d. In premature neonates with CHRs and contraindications for indomethacin, the initial treatment with either ibuprofen or paracetamol failed to close the ductus. However, when this treatment was followed by indomethacin, closure occurred in 66.7% of the neonates, with an outcome period of9.66 d. The initial treatment with one cycle of ibuprofen followed by one or two cycles of paracetamol failed to close the ductus.Conclusions: Oral indomethacin was effective for closure of the PDA in premature neonates with severe CHRs. Oral paracetamol or ibuprofen for PDA closure in premature neonates with severe CHRs and contraindications for indomethacin was ineffective.However, results in clinical improvements of neonates allowed the subsequent use of indomethacin and successful closure of the ductus. A significant reduction of diuresis occurred in neonates who were treated with indomethacin, either as a first-line treatment or after the failure of ibuprofen or paracetamol.

文摘Resting-state functional magnetic resonance imaging has revealed disrupted brain network connectivity in adults and teenagers with cerebral palsy. However, the specific brain networks implicated in neonatal cases remain poorly understood. In this study, we recruited 14 termborn infants with mild hypoxic ischemic encephalopathy and 14 term-born infants with severe hypoxic ischemic encephalopathy from Changzhou Children's Hospital, China. Resting-state functional magnetic resonance imaging data showed efficient small-world organization in whole-brain networks in both the mild and severe hypoxic ischemic encephalopathy groups. However, compared with the mild hypoxic ischemic encephalopathy group, the severe hypoxic ischemic encephalopathy group exhibited decreased local efficiency and a low clustering coefficient. The distribution of hub regions in the functional networks had fewer nodes in the severe hypoxic ischemic encephalopathy group compared with the mild hypoxic ischemic encephalopathy group. Moreover, nodal efficiency was reduced in the left rolandic operculum, left supramarginal gyrus, bilateral superior temporal gyrus, and right middle temporal gyrus. These results suggest that the topological structure of the resting state functional network in children with severe hypoxic ischemic encephalopathy is clearly distinct from that in children with mild hypoxic ischemic encephalopathy, and may be associated with impaired language, motion, and cognition. These data indicate that it may be possible to make early predictions regarding brain development in children with severe hypoxic ischemic encephalopathy, enabling early interventions targeting brain function. This study was approved by the Regional Ethics Review Boards of the Changzhou Children's Hospital(approval No. 2013-001) on January 31, 2013. Informed consent was obtained from the family members of the children. The trial was registered with the Chinese Clinical Trial Registry(registration number: ChiCTR1800016409) and the protocol version is 1.0.
文摘Objectives: To compare groups of etiologic agents for neonatal fungemia based on previously published case reports with regard to case outcomes. Methods: Secondary analysis of data from case reports published in scientific literature indexed in Medline, Scopus and LILACS databases, and starting from the year, full texts were registered until the year 2010. Results: Thirty-four species of fungi were isolated in 252 cases reported over a 40-year period. The distribution of fungal groups according to the development level of a case’s region of origin was very uneven (p Aspergillus sp.) in more developed countries. However, 73% of the chi-squared distribution corresponded to differences observed in the frequency of Candida sp. and non-albicans Candida. While the frequency of candidemia by C. albicans was progressively declining in the period from 1966 to 2010, reports of non-albicans candidemia and other non-Candida fungi became significantly (p albicans Candida or non-Candida fungi were isolated. Conclusion: fungi of the genera Candida and Aspergillus were the etiologic agents most frequently identified in published cases of neonatal fungemia;the outcome of death was more often related to cases where non-albicans Candida or non-Candida fungi were isolated.
