In asphyxiated newborn infants, cholestasis often leads to extensive investigations and a cause can rarely be found. OBJECTIVE: To assess the frequency of transient neonatal cholestasis in an unselected group of asphyxiated newborn infants in a mother-child centre. METHOD: Charts of 181 asphyxiated newborn infants born with appropriate birth weight for gestational age (AGA) or small weight for gestational age (SGA) at Sainte-Justine Hospital, Montreal, Quebec between 1989 and 1993 were reviewed. RESULTS: Transient neonatal cholestasis was found in 8.5% of asphyxiated AGA and 33% of SGA newborn infants, compared with 3.94% cholestasis of any etiology in nonasphyxiated SGA infants. Asphyxiated neonates born before the age of 35 weeks had an increased risk for transient neonatal cholestasis (odds ratio 2.84, CI 1.0-8.1) CONCLUSION: Transient neonatal cholestasis is associated with several contributing factors related to the severity of the neonatal distress. Asphyxia is frequently accompanied by cholestasis in this group of newborns and without symptoms other than uncomplicated cholestasis. Investigations should be focussed on conditions requiring immediate therapy. 相似文献

S ummary . The factor VIII coagulant activity (FVIII :C), factor VIII related antigen (FVIII: RAG), and factor VIII ristocetin cofactor activity (FVIII :RCF) was determined in the cord blood samples of 30 healthy term newborns. Sodium citrate anticoagulant, cold, and a proteolytic inhibitor were used in sample processing. All three factor VIII activities were elevated in infants compared to adults; additionally, FVIII: RAG was significantly higher in vaginally compared with caesarean section delivered infants. Crossed immunoelectrophoresis of the term infant plasma showed a consistently normal factor VIII mobility. An additional group of 22 sick premature and term infants had determinations of factor VIII antigen and crossed immunoelectrophoresis. The FVIII: RAG of sick infants was approximately twice that of the well term infants. Infants with severe lung disease, asphyxia, thrombosis and sepsis had normal electrophoretic mobility despite marked elevations in FVIII: RAG. Abnormal, symmetrical, more anodal migrations were seen only in a group of severely ill newborns with dessiminated intravascular coagulation (DIC) or signs of activated fibrinolysis. These results suggest that the elevated FVIII activities seen in well infants and most sick newborns are the result of increased release of a normal form of the FVIII molecule. Those elevations seen in sick newborns with DIC result from increased release and the production of an altered, faster moving FVIII molecule. 相似文献

The objective of this study was to examine the change in incidence of chronic lung disease following neonatal ventilation in a geographically defined population. Prospective data were collected over two 1-year periods (1987–1988 and 1990–1991) in the Trent Health Region, England. All infants were ≤32 weeks gestation and/or ≤1500g birthweight, born to mothers normally resident in the Trent Health Region. The principal outcome measures were mortality rate, presence of chronic lung disease, days of ventilation, and oxygen used by each infant. The proportion of low gestation, low birthweight babies was 1.5% in each period, made up of 897 and 925 babies from 61,050 and 63,350 births, respectively. There was a significant fall in mortality in infants of 750–1500g birthweight. However, the incidence of chronic lung disease (using either of two definitions) rose significantly between the two periods, with a corresponding large rise in the amount of respiratory care required. The contribution of various antenatal factors previously thought to be related to the development of chronic lung disease was examined. Birthweight and gestation were shown to be of overwhelming significance. We concluded that improvements in neonatal care, including the introduction of surfactant therapy, improved survival for some infants at the expense of an increased incidence of chronic lung disease. Clearly the hoped-for cost saving following the introduction of surfactant therapy has not occurred. Pediatr Pulmonol. 1996; 21:24–27 . © 1996 Wiley-Liss, Inc. 相似文献

Free radicals have been implicated in the pathogenesis of neonatal asphyxia and its complications. This study measured a product of lipid peroxidation, malondialdehyde, and the nitrite/nitrate levels in the serum of 20 asphyxiated newborns before and after treatment with the antioxidant melatonin given within the first 6 hr of life. Ten asphyxiated newborns received a total of 80 mg of melatonin (8 doses of 10 mg each separated by 2-hr intervals) orally. One blood sample was collected before melatonin administration and two additional blood samples (at 12 and 24 hr) were collected after giving melatonin. A third group of healthy newborn children served as controls. Serum malondialdehyde and nitrite+nitrate concentrations in newborns with asphyxia before treatment were significantly higher than those in infants without asphyxia. In the asphyxiated newborns given melatonin, there were significant reductions in malondialdehyde and nitrite/nitrate levels at both 12 and 24 hr. Three of the 10 asphyxiated children not given melatonin died within 72 hr after birth; none of the 10 asphyxiated newborns given melatonin died. The results indicate that the melatonin may be beneficial in the treatment of newborn infants with asphyxia. The protective actions of melatonin in this study may relate to the antioxidant properties of the indole as well as to the ability of melatonin to increase the efficiency of mitochondrial electron transport. 相似文献

The EEG of the newborn consists of a mixed activity which varies from 1 to 22/s. Waves in the alpha band may occur, but they indicate cerebral dysfunction if they are seen in a rhythmic uninterrupted sequence. Eight newborns who showed rhythmic alpha activity in their EEG are included in our study. This activity occurred together with rhythmic theta waves or was followed by them as part of ongoing electrographic seizure activity. All newborns studied were very sick. Three suffered from severe perinatal asphyxia with persistent fetal circulation; in addition one of them had bacterial meningitis. Two infants suffered from herpes encephalitis. In those cases the rhythmic alpha activity temporarily showed a certain periodicity. This EEG pattern was also seen in a small for gestational age premature infant who had septicemia and subarachnoid hemorrhage and in two extremely premature babies with intraventricular hemorrhage. Four infants were curarized. All of the others also had clinically observed seizures. Rhythmic alpha-activity in the neonatal EEG represents an electrical seizure discharge. It may also occur in premature infants who suffer from intraventricular hemorrhage. Obviously it does not have a diagnostic value. The prognostic value depends upon the underlying disease and the grade of background suppression in the EEG. Anticonvulsant therapy should be administered early using a sufficient dosage. 相似文献

Neonates are easily prone for bacterial infection. Diagnosis of neonatal septicemia may be difficult as the early signs of
sepsis may be subtle and different at different gestational ages. The present study was undertaken to assess the significance
of the hematological scoring system (HSS) for early detection of neonatal sepsis. About 50 peripheral blood smears of all
newborns collected were analysed for neonatal sepsis using the HSS of Rodwell et al. (J Pediatr 112:761–767, 1988). Analysis
in our study found that an abnormal immature to total neutrophil ratio (I:T) followed by an abnormal immature to mature neutrophil
ratio (I:M) were the most sensitive indicators in identifying infants with sepsis. The HSS is a simple, quick, cost effective
tool which can be used as a screening test for early diagnosis of neonatal sepsis. 相似文献

Gastric ulcer bleeding in neonatal period, mainly in preterm newborn babies or in neonates treated in intensive care units, is relatively frequent, However the occurrence of significant gastric ulcer bleeding in healthy full term infants is unusual. We experienced a case of massive upper gastrointestinal (GI) bleeding in a 3-day-old healthy full term infant. Endoscopic examination confirmed the presence of gastric ulcerations. Treatment was initiated with transfusion and histamine 2 receptor antagonist, and the clinical signs resolved. Mother's serum antibody to Helicobacter pylori (H. pylori) was positive. We collected stool of the patient including other 17 infants in the intensive care unit. A highly sensitive semi-nested PCR for H. pylori DNA was performed, but all infants including the patient revealed negative. H. pylori infection is not related with upper GI bleeding in healthy full term infants. In conclusion, the diagnosis of upper GI bleeding in infant can be easily made by means of pediatric endoscopy, which is a simple and a well tolerated examination. 相似文献

The case of a woman who in two successive pregnancies produced premature infants affected by early-onset Streptococcus pneumoniae type 8 sepsis is described. Low maternal levels of pneumococcal IgG antibodies were demonstrated after the second delivery, and vaccination with 'Pneumovax' produced a rise in antibody levels. Attention is drawn to the similarity between early-onset pneumococcal neonatal sepsis and group B streptococcal sepsis. Mothers of infants affected by early-onset pneumococcal sepsis who have low pneumococcal antibody levels run the risk of subsequent babies being similarly affected and vaccination should be considered to prevent recurrence. 相似文献

Neonatal morbidity and mortality still poses a serious challenge in developing countries. Low level of obstetric care, unsupervised home deliveries and late referrals lead to poor outcome even in special care baby units (SCBU). To identify the common causes of neonatal morbidity and mortality among babies admitted to the SCBU in Aminu Kano Teaching Hospital (AKTH) the case-notes of all admitted neonates from January 1998 to December 2004 were retrospectively reviewed. A total of 2963 (98.3%) babies had complete records. There were 1455 (49.1%) in-born (delivered in AKTH) and 1508 (50.9%) out-born (delivered elsewhere) babies. The sex ratio was 1.25:1 in favour of males. A total of 1868 (63.0%) were of normal birth weight, while 951 (32.1%) and 134 (4.5%) were low birth weight and macrocosmic, respectively. The leading diagnoses were birth asphyxia (27%) (severe birth asphyxia 18.1%, moderate asphyxia 8.9%), neonatal sepsis (25.3%) and prematurity (16.0%). Out of the 2963 babies, 501 (16.9%) died. The risk of dying was significantly higher (20.5%) among out-born babies compared with those delivered in AKTH (6.4%) (odds ratio = 1.71, 95% confidence interval = 1.4-2.1). In conclusion, the causes of neonatal morbidity and mortality at this centre are similar to those reported from other units. They could be prevented through effective antenatal care, supervised delivery and appropriate care and early referral of sick neonates. 相似文献

Fetal echocardiography facilitates the prenatal diagnosis of infants with congenital heart disease (CHD) and through sequential examinations, allows assessment of fetal hemodynamics and cardiovascular status from the time of diagnosis to delivery. Fetal cardiologists have created diagnostic protocols aimed at risk stratifying severity and potential postnatal compromise in fetuses with CHD, and identifying those who may require special intervention at birth or within the first days of life. In this article, we review fetal cardiovascular physiology, the progression of CHD in utero and fetal echocardiographic findings used for risk stratification of newborns with CHD, as well as some of the basic principles of planning for the neonatal resuscitation and initial transitional care of these complex newborns. 相似文献

Insulin degludec is an extra‐long‐acting insulin analog that allows for enhanced efficacy and flexibility in the injection time. However, it is not approved for use during pregnancy. We report the pregnancy outcome and newborn conditions in two women with type 1 diabetes who continued preconception degludec treatment during embryogenesis. No pregnancy complication or congenital neonatal malformation was observed. Both babies presented with hypoglycemia and required neonatal intensive care unit admission. Degludec treatment did not cause adverse effects in the mothers or malformations in the newborns. The observed neonatal complications were probably independent of early pregnancy degludec treatment. 相似文献

The objective of this cross-sectional study was to evaluate the association between prenatal care visits and infant birthweight among ethnic minority mothers in the mountainous Bac Kan province.This was done by comparing the frequency and timing of first prenatal care visit of 32 mothers with low birthweight (LBW) infants and 32 mothers with normal birthweight (NBW) infants. During pregnancy, mothers of NBW infants underwent 3.4+/-1 (mean) prenatal care visits and mothers of LBW infants 2.8+/-0.9 (P = 0.02). Mothers of NBW infants underwent their first prenatal care visit at 13.1+/-5.7 weeks of gestation, one week earlier than mothers of LBW infants. The frequency of prenatal care visit are probably associated with a decreased risk of LBW among ethnic minority mothers in Bac Kan province. 相似文献

OBJECTIVE: We aimed to examine birthweight, low birthweight (<2500 g), and intrauterine growth retardation in offspring of women with celiac disease in relation to their first hospitalization for the disease. METHODS: This was a historical cohort study based on The Danish Medical Birth Registry data of celiac women discharged from Danish hospitals from 1977-1992. The study included 211 newborns to 127 mothers with celiac disease, and 1260 control deliveries. RESULTS: Before celiac women were first hospitalized the mean birthweight of their newborns was 238 g (95% confidence interval [95% CI] = 150, 325 g) lower than that of the control women, after adjustment for potential confounders. After the first hospitalization the mean birthweight for newborns of diseased women was higher than that of controls, by 67 g (95% CI = -88, 223 g) after adjustment for potential confounders. Before celiac women were first hospitalized we found an increased risk of low birthweight (odds ratio [OR] = 2.6, 95% CI = 1.3-5.5) and intrauterine growth retardation (OR = 3.4, 95% CI = 1.6-7.2). After celiac women were first hospitalized we found no increased risk of low birthweight and no babies with intrauterine growth retardation. CONCLUSIONS: Offspring of mothers with celiac disease had lower birthweight than expected and more than a three-fold higher risk of intrauterine growth retardation when birth occurred before the first hospitalization for the disease. After the mother's first hospitalization the birthweight was similar to controls and no increased risk of low birthweight was seen. Our study indicates that treatment of celiac women is important in the prevention of fetal growth retardation. 相似文献

Summary The sixth newborn and second premature infant to have survived perforation of a gastric ulcer has been reported.Cold is implicated as an additional stress of possible significance in the formation of peptic ulcers. Hypothermic infants with other signs or symptoms of neonatal cold injury (lethargy, redness of skin, edema, sclerema) should be observed especially carefully for evidence of an ulcer.Refusal of feedings, even mild abdominal distention, or vomiting should alert one to the possible indication for abdominal films, as early surgical intervention is essential to the salvage of newborns with this condition.Presented at the Seventh Annual Symposium of Air Force Internists and Allied Specialists at the Wilford Hall USAF Hospital, Lackland AFB, Tex., on Feb. 7, 1964.The author wishes to express his appreciation for the editorial assistance of Dr. John H. Githens, Dr. John J. Boehm, and Dr. William E. Hathaway. 相似文献

Malassezia furfur and Candida albicans are fungal pathogens which have been recognized with increasing frequency as agents of mortality and serious morbidity in neonatal intensive care unit patients. A longitudinal study of oral, rectal and umbilical colonization by these organisms of newborns admitted to a neonatal intensive care unit within 24 h of birth was undertaken. Of 71 infants followed for a minimum of 10 days, 24 were colonized with M furfur and 12 with C albicans during the first 10 days of life. The lower gastrointestinal tract was found to be the most common colonization site for both organisms. Statistically significant (P<0.05) inverse associations were demonstrated between gestational age and risk of colonization with either organism at any site, and between birthweight or gestational age and risk of rectal colonization with either organism. Antibiotics were associated with a relative risk colonization of 4.06 (P=0.06) with either organism at any site. It is concluded that M furfur and C albicans are common colonizing organisms in a neonatal intensive care unit setting and are most frequently harboured in the lower gastrointestinal tract. M furfur, recently implicated as a systemic pathogen in this population, has not been previously recognized as a gastrointestinal commensal organism. The relationship between colonization and invasive fungal disease, and potential roles for preventive strategies, remain to be elucidated. 相似文献

AIMS: To assess pregnancy outcomes, in particular birthweight, in a large population-based cohort of women in Scotland with pre-gestational insulin-treated diabetes mellitus. METHODS: Data about diabetes from the Diabetes UK cohort were linked to data on births from the Scottish Hospital In-Patient Record System. This identified 1112 eligible singleton deliveries during 1979-95 to 706 insulin-treated women. RESULTS: One thousand and eighty-four (97.5%) deliveries resulted in a live-born infant and 28 (2.5%) in a stillbirth. There were 13 (1.2%) neonatal deaths. The mean birthweight of the live-born infants was 3421 g, 1.06 standard deviations greater than that of infants in the Scottish general population after correcting for sex and gestational age. Forty-three per cent of live-born babies in the study were large (> Scottish 90th percentile) and 4% small (< 10th percentile) for their sex and gestational age. Macrosomia, defined as birthweight > or = 4000 g, occurred in 23% live-born babies and its prevalence was significantly inversely related to duration of maternal diabetes. However, the mean birthweight of infants born to mothers with diabetes for 20 or more years was still 0.90 standard deviations greater than in the general population. Prevalence of macrosomia increased with increasing number of previous pregnancies, but was not associated with maternal height or smoking habits. Stillbirth and neonatal death rates were, respectively, 4.7 (95% confidence interval = 3.3, 6.8) and 2.4 (1.4, 4.1), times higher than those in the general population. CONCLUSIONS: The frequency of adverse pregnancy outcomes in women with pre-existing insulin-treated diabetes was much higher than in the Scottish general population, and changed little during the study period. A detailed quantification of the independent effect of duration of mother's diabetes on birthweight revealed a continuous inverse correlation between these two variables. 相似文献

Thrombocytopenia is one of the common hematological problems encountered in the neonatal period particularly in the sick newborns, premature babies and neonates admitted in neonatal intensive care units and usually indicate an underlying pathologic process. Thrombocytopenia is reported in neonates with bacterial, fungal, rickettsial, protozoal and viral infection. Some patients with bacterial septicemia may develop coagulopathy associated with DIC. The presence of thrombocytopenia is seen frequently in early sepsis with or without laboratory evidence of overt DIC. This study was conducted on 85 neonates admitted in NICU with clinical diagnosis of septicemia and 50 age and weight matched neonates served as control. Thrombocytopenia was seen in 83.5% cases where as bacterial culture was positive in only 41.1% cases. Further it was noted that, in gram negative (Gm −ve) septicemia, thrombocytopenia was more severe as compared to gram positive (Gm +ve) septicemia. It is concluded that thrombocytopenia is early predictor of septicemia but other causes of neonatal thrombocytopenia should also be ruled out.

The objective of this study was to compare the incidence of chronic lung disease following neonatal ventilation in two geographically defined populations. Prospective data collection was carried out over a 1 year period from March 11, 1990 to February 28, 1991 in the Trent Health Region (England) and in British Columbia, Canada. All infants ≤32 weeks gestation and/or ≤1500 g birthweight born to mothers normally resident in either the Trent Health Region or British Columbia were included. The main outcome measures were mortality rate, presence of chronic lung disease, days of ventilation, and oxygen used by each infant. The proportion of shortened gestation, low birthweight babies was 1.5% in Trent and 1.2% in British Columbia (957 of 63,350 births in Trent and 526 of 45,333 births in British Columbia). There were no significant differences in mean birthweight or gestation between the two cohorts, but there was a trend towards lower mortality for infants 750–1500 g birthweight in British Columbia. The incidence of chronic lung disease (using either of two definitions) was significantly higher in British Columbia, with a corresponding greater amount of respiratory care required. This occurred despite higher use of antenatal steroids and surfactant therapy in the British Columbia group. We conclude that there are important clinical and resource implications resulting from the number of ventilator and oxygen days used by the preterm population in terms of planning of neonatal services. The role of individual treatment modalities in producing differences in the incidence of chronic lung disease warrants further study in the setting of a geographically defined population.

The relationship between the serum level of maternal transferrin in late pregnancy and the birthweight of the infant was investigated. Mothers with low levels of serum transferrin may give birth to low-birthweight babies, but this was not a general phenomenon. In very-low-birthweight infants, the birthweight correlated with the level of maternal transferrin. It is concluded that the maternal serum transferrin level does not reflect the maturity of the fetus or the birthweight of term neonates. 相似文献
