In order to reduce the mortality and cerebral injury, the pathogenesis and early diagnosis of the neonatal brain edema(NBE) were explored. 583 cases with NBE were diagnosed by autopsy during 1962~1998 to study their pathogenesis. Symptomes and signs of 63 cases with NBE were analyzed with high risk factors such as asphyxia, abnormal labor, complications before and during partum, at 3~7th day after birth by cerebral CT scan during 1998~1999. Results showed 1. The pathogenesis of 583 cases were brain...

In order to reduce the mortality and cerebral injury, the pathogenesis and early diagnosis of the neonatal brain edema(NBE) were explored. 583 cases with NBE were diagnosed by autopsy during 1962~1998 to study their pathogenesis. Symptomes and signs of 63 cases with NBE were analyzed with high risk factors such as asphyxia, abnormal labor, complications before and during partum, at 3~7th day after birth by cerebral CT scan during 1998~1999. Results showed 1. The pathogenesis of 583 cases were brain 267 cases(45 8%), lungs 223 cases(38 3%), Infectious diseases 52 cases(8 9%), heart 35cases(6 0%),malformations 6 case (0 85%). 2. In 63 cases diagnosed by CT scan, there were SAH 60 cases, HIE 48 cases, IPH and hydrocephalus 2 cases each, Intracranial infarcts, SDH,IVH were 1 case each. 3.The clinical symptomes and signs of NBE included irritability or inhibition, cyanosis or gray, respiration irregular, hypo or hypertonia, and abnormal reflexes. We can conclude 1. Hypoxemia is the main cause of NBE. 2. Cerebral ultrasound and/or CT scan is valuable for the early dignose of NBE in high risk infants.

Objective To analyze the relationship between clinical characteristics and prognosis of neonatal cerebral infarction and to draw attention to the disease to improve the long term outcome through early diagnosis and intervention. Methods The clinical characteristics of 6 confirmed cases were summarized. Perinatal conditions and other factors were analyzed for possible causes of the disease. The survived patients were followed up for 6 8 months.Results The authors diagnosed 6 cases of neonatal cerebral infarction in one year, which accounted for 0 6% (6/969)of all the in patients in the same time period. Among them 3 cases were confirmed as cerebrovascular malformations by magnetic resonance angiography (MRA), In 1 case the infarction was due to severe bilateral intraventricular hemorrhage, and in another case the disease was related to comprehensive factors such as prematurity, maternal pregnancy induced hypertension and respiratory failure secondary to bronchopulmonary dysplasia (BPD), and in 1 case the cause was undetermined. Four out of the 6 patients presented with varied forms of convulsions, which became the second leading cause for all the neonatal convulsive events (20%). None of the patients had localized neurological signs in the early course except for abnormal muscular tone of some extent. Cerebral ultrasound scanning in 5 out of 6 cases showed positive results. The diffusion weighted magnetic resonance imaging (DW MRI) was highly valuable for early confirmative diagnosis. Only one case was found normal within one year of follow up and all the other 5 cases had unfavorable prognoses of varied severity.Conclusion Neonatal cerebral infarction is not a rare condition and should be considered as one of the important causes for neonatal convulsion. Imaging study is the main technique for diagnosis. The prognoses were poor for those cases for whom early diagnosis and treatment can not be made or those with widespread cerebral lesions.

目的 分析新生儿脑梗死的临床特征与预后的关系 ,并通过早期诊断和干预 ,以改善本病的远期预后。方法 总结 6例确诊病例的临床特征 ,进行围产期因素和其它可能病因分析 ,并对存活患儿进行 6~ 8个月的随访。结果  1年内发现 6例新生儿脑梗死 ,占同期住院患儿 0 6 % (6 /96 9)。6例中 3例经MRA确诊为脑血管畸形 ,1例为严重脑室内出血 ,1例与早产、母亲患重度妊娠高血压综合征及继发于支气管肺发育不良的呼吸衰竭等综合因素有关 ,1例原因不明。本组 4例 (4 /6 )出现各种形式惊厥 ,占同期新生儿惊厥的 2 0 % (4 /2 0 ) ,是引起新生儿惊厥的第二位原因 ;6例在早期均无定位体征 ,仅有部分患儿表现为肌张力异常。头颅B超示 6例中 5例有阳性发现 ;弥散加权核磁共振成像 (DW MRI)能够做到早期准确诊断。 1例随访至 1岁未发现异常 ,其余 5例均有不同程度不良预后。结论 新生儿脑梗死并不少见 ,而且是新生惊厥的重要原因之一 ,影像检查是本病主要确诊方法 ,未能早期诊治和累及范围较广者预后不良

Objective To study the effect of maternal diabetes during pregnancy on brain deve lopment of filial generation. Methods Cerebral gyri width of lobus frontals was measured in 79 infants of pregnant diabetic mother by ultrasound and the parameters were compared with 108 infants of non diabetic mother. We analyzed the relationship between the variation of cerebral gyri width and the diabetic control of the mothers. Brain development status in neonates with diabetic mothers was observed. Results Cerebral gyri width were significantly wider in the full term infants of diabetic mother (1.006±0.102)cm than that of the infants of non diabetic mother (0.859±0.087)cm. This was more obvious in the gyrus frontals superior and initial section[(1.167 ±0.197)cm vs (0.956 ± 0.123) cm]( P <0.01). The rate of infantile abnormal cerebral gyri width of un controlled maternal diabetes (47%) was higher than that of control groups (37%, P >0.05). Conclusions Maternal diabetes in pregnancy may result in filial generation brain immaturity. Cerebral ultrasound can be used to measure the cerebral gyri width.

目的 探讨母亲孕期糖尿病对子代脑发育的影响。 方法 通过颅脑超声测量 79例糖尿病母亲之新生儿额叶脑回宽度 ,与 10 8例同胎龄非糖尿病母亲的新生儿相比较 ,并分析母亲糖尿病控制情况与新生儿脑发育的关系及受母亲疾病影响的新生儿脑回宽度变化。 结果 糖尿病母亲之足月新生儿额上回宽度 (1.0 0 6± 0 .10 2 )cm及其起始段脑回宽度 (1.16 7± 0 .197)cm与非糖尿病母亲之新生儿 [额上回宽度 (0 .85 9± 0 .0 87)cm ,起始段脑回宽度 (0 .95 6± 0 .12 3)cm]比较 ,差异有显著性 (P <0 .0 1)。母亲孕期糖尿病未控制组新生儿额叶脑回宽度异常率 (47% )高于控制组 (37% ) ,但差异无显著性 (P >0 .0 5 )。受母亲糖尿病影响的新生儿脑发育过程中出现问题机会较高。 结论 母亲孕期患糖尿病有可能造成子代脑成熟障碍 ,可通过颅脑超声对新生儿脑回宽度测量予以评价。
