Four observations of intraventricular hemorrhage in full term neonates without perinatal asphyxia are reported. The clinical pictures were remarkably similar in the four infants: neurological symptoms developed several days after birth with sunsetting and eye deviation and symptoms of cranial hypertension. Ultrasonography and CT scan showed a thalamic hemorrhage.
Premature newborns suffering from respiratory distress and asphyxiated term newborns may present transient symptomatic neonatal hyperammonemia associated with reversible neonatal coma. As they survive they may develop normally; however the authors emphasize the importance of concomitant hemodynamic disorders and the extreme frequency of brain hemorrhage and ischemia. Ultrasonography or tomodensitometry are necessary for prognosis.
Cerebral abscess is considered as a rare lesion with severe prognosis in neonates. The present means of cerebral imaging allow for a better estimation of its frequency, a more precise diagnosis of the evolutive stage and the estimation of the efficacy of the treatments. Incision-drainage associated with antibiotic treatment was successful in children. Two cases of neonatal cerebral abscesses treated and cured according to this protocol are reported.

A case is reported of a term newborn with intra uterine growth retardation and numerous malformations such as complex heart disease, abnormalities of distal limbs, cleft palate. Death occurred after two days. The diagnosis of rubella embryopathy was confirmed by the following criteria: a high level of rubella antibodies in mother and newborn (1/1000) an isolation of rubella virus from the infant's urine. Diagnosis of rubella after reinfection was documented by a high level of antibodies in the mother three years before this pregnancy. Other observations reported in literature confirm the extreme rarity of congenital rubella after reinfection.
Variations of lactose and oligosaccharides in human milk were studied over a 3-month lactation period by dialysis, chromatography on Bio-gel P-2 column, paper chromatography, colorimetric analysis and gas chromatography. Milk samples were collected from donors of various blood and secretor types. An increase in the concentration of lactose was noted: 59.25 +/- 1.61 to 72.17 +/- 1.35 g/l for the group of secretor A secretor Lea Leb individuals, and from 62.25 +/- 1.35 to 73.15 +/- 3.45 g/l for the group of secretor H secretor Lea Leb individuals. A decrease in the concentration of oligosaccharides was also found: from 16.71 +/- 0.99 to 7.90 +/- 1.29 g/l and from 18.51 +/- 0.74 to 7.33 +/- 0.65 g/l, respectively, for these same groups. In secretor H nonsecretor Lewis individuals, the concentration of lactose increased from 67.97 +/- 3.09 to 77.42 +/- 1.88 g/l, and the concentration of oligosaccharides decreased from 13.27 +/- 0.40 to 3.47 +/- 0.33 g/l. Analysis of oligosaccharide composition by chromatography showed that variations are in relation to the secretor Lewis type. All oligosaccharides decreased equally throughout the lactation period, regardless of the blood group. The decrease was more rapid, however, in the nonsecretor Lewis individuals. In these individuals, the absence of certain oligosaccharides is not compensated by an overproduction of the other oligosaccharides present or by biosynthesis of structurally different oligosaccharides. The origin of these oligosaccharides is discussed.
Case-report of neonatal Marfan Syndrome with at birth the following observations: arachnodactyly, excessive length of arm, cardiac anomalies with hemodynamic troubles leading to death within 4 days. Anatomical data of the postmortem examination and histologic anomalies of the aorta confirm the diagnosis. No case of Marfan syndrome are to be found among forebearers. These characteristics underline the rarity, the gravity of the pronostic and the often sporadic appearance of the Marfan syndrome when revelated in the neonatal period.
A case of neonatal giant lobar emphysema secondary to a complex cardiac anomaly with pulmonary valvular agenesis is presented. Clinic and radiologic findings are sufficient to suggest diagnosis. Right heart catheterization is required to demonstrate the pulmonary valvular agenesis. Such an investigation should be recorded when observed a giant neonatal emphysema. Is failure occurs in the neonatal period the prognosis of this association is poor.
The authors report a case of post natal hernia with group B beta hemolytic streptococcus infection. The frequency of such an association compared to the rarity of delayed onset congenital diaphragmatic hernia may constitute a reflexion subject. The literature is reviewed and a concept of pathogenesis is discussed.
This paper relates two cases of a complex syndrome with unusual facies, restricted articular movements and accelerated skeletal maturation (already present at birth) in two siblings (brother and sister). These infants died in early age: one was ten days, the other six weeks old. Clinical and radiological findings of these newborns are part of both the Marshall-Smith and the Weaver syndrome, suggesting that these syndromes are one entity. The observation of affected siblings from unaffected parents favors autosomal recessive inheritance.
In a six weeks old infant an hepatic abscess with several affected areas is diagnosed by ultrasonography confirmed by scintillation scanning. Closed percutaneous needle aspiration and antibiotherapy permitted a good outcome avoiding surgical drainage or excision.
A case of bacterial endocarditis in a newborn without any congenital heart disease is reported. The clinical diagnosis was suspected on evolutive heart failure by mitral dysfunction with sepsis. T.M. mode echocardiography could detect only the valvular defects. Correlations between anatomic and echocardiographic findings allowed to discuss the limits of the method. Neonatal bacterial endocarditis is a rare event. Its diagnosis is difficult and its prognosis very poor. This affection must be prevented.
The post-prandial pattern of total serum bile acids was studied in 47 newborns: 12 prematures (less than 36 weeks), 17 term low-birth-weight infants (less than the 3rd percentile), 18 term normals. The study was made at the end of the first month. Blood was collected in a peripheral vein using a microcatheter. Samples were taken at fasting time and 30, 60, 120, 180 min after a test meal intake (40 ml/kg of "humanized" milk based formula). Bile acids were assayed using an original enzymatic micromethod which needed only 50 microliter of serum and showed a sensitivity of 0.3 pmol in 200 microliter of reaction medium. The response of serum bile acids after the test meal was very similar in normal term newborns and in adults. Prematures exhibited bile acid levels slightly higher than normals, but this difference was significant only at 0 and 180 min. Low-birth-weight infants showed very high values of serum bile acids at all times during the test, compared to normal and premature infants. Serum levels of total bilirubin and alkaline phosphatase were similar in all 3 groups. These results are not consistent with cholestasis but rather indicate a specific dysfunction in bile acid metabolism in low-birth-weight infants.
A double-blind trial was carried out in 62 depressed patients to compare the clinical efficacy and acceptability of amineptine and clomipramine. Patients were allocated at random to one or other of two treatment groups and received daily doses of amineptine ranging from 100 to 300 mg (mean 180 mg) or of clomipramine ranging from 50 to 150 mg (mean 84 mg) over a period of 6 weeks. Global assessment of response to treatment and Hamilton Rating Scale scores, assessed before and after 1,3 and 6 weeks of treatment, indicated that the two drugs appeared to be equally effective and no differences between them could be demonstrated in the analysis of the individual items or grouped items of the scale used. Measurements of ocular tone showed that there was significantly less risk of amineptine producing an increase in tone, and blood pressure and electrocardiographic investigations also underlined the greater cardiovascular tolerance of amineptine. Five (16%) of the 32 patients in the clomipramine group were withdrawn from the study because of adverse effects.
In a 15 day-old infant who presented with heart failure on the 4th day of life, the discovery of a continuous murmur at the level of the cranium led to suspicion of an aneurysm of the vein of Galien. Chest and neck profile X-rays showed an enlargement of the great vessels at the base of the heart and a thickening of the retropharyngeal soft tissues. Cerebral echotomography through the fontanelle showed an anechoic round area located in the posterior part of thalamus. Cerebral angiography confirmed the diagnosis.
