[Neonatal pneumococcal septicemia].

We report two cases of neonatal pneumococcal septicemia, including one fatal case in a 32-week-gestational-age premature infant. Neonatal pneumococcal septicemias account for less than 1% of all neonatal infections. Diagnosis is provided by simple and rapid methods for identifying pneumococci. Clinical features have little specificity (respiratory distress) and resemble those found in B streptococcus infections. The mother rarely exhibits symptoms at delivery. The severity of the prognosis is not related to resistance to the antimicrobial agents currently used in neonatal infections but to the infectivity of the organism itself and to the specific immunologic characteristics of premature neonates. The current use of amoxicillin and aminoglycosides in neonatal infections does not therefore need to be revised.

[Metabolic and cardiovascular effects of beta-blockers taken by the mother in newborn infants].

The effects of beta-blockers administered to mothers with arterial hypertension were investigated in 38 neonates of varying gestational age and weight. During the first 48 hours of extra-uterine life, heart rate was continuously monitored and blood pressure and glycaemia were measured every 3 hours. Left ventricular function was studied by echocardiography on the first day post-partum, once again between the 5th and 10th days. Hypoglycaemia was observed in 42% of the neonates; 47% had one or several episodes of bradycardia and 2 had arterial hypotension. Most important, a significant improvement of left ventricular function was observed between the first and the 5th-10th days. This time-related change was not found in a control group. The cardiac dysfunction was more pronounced in neonates who had an episode of bradycardia, and although it is usually asymptomatic, it probably accounts for the fortunately rare cardiovascular collapses observed in some newborn babies.

[Value of continuous Doppler velocimetry for the diagnosis of patent ductus arteriosus].

A study of the curve of wave Doppler ultrasonography of 3 arterial axes (carotid, subclavian and femoral) was performed in 32 children in whom the diagnosis of patent ductus arteriosus was suspected. A continuous 8 MHz wave directional ultrasonic Doppler apparatus was used. At the level of subclavian and femoral arteries, patent ductus arteriosus is associated with a negative holodiastolic wave on the curve. At the carotid level, disappearance of the physiologic diastolic elevation may be the only change observed. Three groups were studied (1) 15 premature neonates with isolated murmur, (2) 15 premature neonates with respiratory distress and (3) 2 older children. In group 2, diagnosis of patent ductus arteriosus relies on clinical signs. A good correlation between Doppler and clinical data and/or TM ultrasonography was observed in 93% of cases.

[Case of giant intra-petrous and intra-cavernous internal carotid aneurysm in a child].

The authors report the case of an eight-year-old girl hospitalised for severe headache with paroxysmal left otalgia, vomiting, aprexia, paralysis of the left 6 th cranial nerve and slight left facial weakness. Left carotid arteriography revealed a very large aneurysm of the internal carotid, involving its entire intra-petrous and intra-cavernous course. Treatment consisted of ligation of the internal carotid in the neck. Postoperative angiographic studies showed complete exclusion of the aneurysm, and it was unecessary to carry out "trapping" by ligation of the supra-cavernous carotid, as had initially been envisaged. The postoperative course was uneventful : immediate disappearance of otalgia, secondary complete recovery of the oculo-motor involvement and facial paresis. The absence of any infections or traumatic past history, together with the young age of the patient, represent arguments in favour of the congenital origin of this intra-petrous carotid aneurysm.
