[Early myoclonic encephalopathy. Delimitation of the syndrome in view of genetic counseling].

Early myoclonic encephalopathy is a rare neurologic disease of unknown etiology whose course is always quickly unfavorable. Clinical features include lack of mental development and myoclonic jerks which appear during the neonatal period. There are no biological abnormalities but EEG shows a pattern of suppression-burst. In the spectrum of neonatal epileptic encephalopathic syndromes, it is important to distinguish this syndrome from non-ketotic hyperglycinemia and Ohtahara' syndrome. Two new familial cases authors to emphasize on the difficulty of nosological delineation of these syndromes. However it is necessary to delimit this disease for a genetic purpose.

Maturation of peripheral nerves in preterm infants. Motor and proprioceptive nerve conduction.

The peripheral nerve maturation (proprioceptive and motor nerve conduction velocities (PNCV and MNCV] was studied in 3 groups of newborn babies. Two groups of premature babies (PT), studied when they reached the expected date of birth (group I, gestational age (GA) at birth 27-31 weeks, n = 13, group II, GA at birth 32-35 weeks, n = 9), were compared to 10 normal full-term newborns (FT). The MNCV of PT babies was similar to that of FT babies: group I 22.8 +/- 3.3 m/sec (X +/- S.D.), group II 24.9 +/- 4.3 m/sec, FT 25.7 +/- 3.9 m/sec. PNCV was significantly lower in group I (18.1 +/- 5.9 m/sec) than in group II (28.3 +/- 6.4 m/sec) and in FT babies (32.0 +/- 7.4 m/sec) (P less than 0.001). Such a delay in maturation could be partly responsible for the neurological impairment often observed in PT babies.

[Hemorrhagic colitis in newborn infants. Apropos of 32 cases].

The authors report 32 cases of neonatal hemorrhagic colitis observed during a 19-mth period in the neonatal unit of the University Medical Center of Caen. Neonatal hemorrhagic colitis is characterized by rectal bleeding alone occurring mostly in premature infants. There are no accompanying clinical, biological or radiological signs of necrotizing enterocolitis. The evolution is always benign without any particular therapy. Prematurity and cesarean section appear to be the most important etiological factors. The pathogenesis is probably multifactorial. The differential diagnosis with necrotizing enterocolitis is difficult in the beginning.

Maturation of peripheral nerves in preterm infants: proprioceptive and motor nerve conductions of tibial nerve.

Premature birth induces a profound change in the environmental factors affecting nerve maturation. The proprioceptive sensory and motor nerve conduction velocities (NCV) of the posterior tibial nerve, which reflect peripheral nerve maturation, have been measured in 3 groups of newborns. Two groups of premature (PT) babies, studied when they reached the expected date of birth (group I, gestational age (GA) at birth, 28-31 weeks, n = 8; group II, GA at birth, 32-35 weeks, n = 6) were compared to 9 normal full-term (FT) newborns. As previously shown, the motor NCV of PT babies at a post-conceptional age close to term is similar to that of FT newborns: group I, 22.70 +/- 2.95 m/s (mean +/- SD); group II, 25.90 +/- 4.61 m/s; FT, 25.48 +/- 4.09 m/s. The proprioceptive sensory NCV was significantly lower in group I (21.59 +/- 4.39 m/s) than in group II (31.89 +/- 4.15 m/s) and FT newborns (32.22 +/- 6.56 m/s) (p less than 0.01). Such a delay in maturation could be responsible for the subtle clinical dysfunctions often observed in PT babies.

[Nutritional management of neonates and infants with cystic fibrosis of the pancreas detected at birth].

From a systematic neonatal screening for cystic fibrosis in the Basse-Normandie area and to prevent disorders of the intestinal transit related to malabsorption, neonates then infants were given a semi-elemental hypercaloric diet, with supplements in nitrogen, MCT, minerals, vitamins and low in LCT. Diets were adjusted every month during a consultation using clinical and biological parameters. Results in the first 14 children showed that clinically as well as biologically, these children may remain within the normal range, avoiding the previously reported growth retardation and mineral or vitamin deficiencies. This procedure should allow an improvement in the quality of life and prognosis of such children, by maintaining adequate nutritional status.

[Di George's syndrome complicated by graft versus host reaction].

On the occasion of a case of Di George syndrome, complicated by a post-transfusion lethal graft versus host reaction, the authors review its main clinical and biologic criteria. This case also shows that immune deficiencies should be diagnosed early in order to adopt preventive measures before transferring the patient in a specialized unit, where immunorestitution will be discussed.

[Cardiac tumors with neonatal disclosure. Apropos of a case with spontaneously favorable development].

The authors report the case of a cardiac tumour documented by 2 D echocardiography, presenting in the newborn with cardiac arrest. The echocardiographic features of multiple nodules disseminated in the ventricular walls suggested a diagnosis of rhabdomyoma. The initial course was complicated by poorly tolerated attacks of tachycardia which were rapidly brought under control with amiodarone. The long term outcome was clinically favourable with a rapid regression of the number and size of the tumours on echocardiography, and a tendency to normalisation of the electrocardiogramme. The possibility of regression, which has already been reported by many investigators, suggests that these cardiac tumours may have a better prognosis than previously thought.

[Refractory hypoxemia in the newborn. Treatment with tolazoline].

Persiting pulmonary arterial hypertension, whether secondary to known lung disease or apparently idiopathic, may induce refractory hypoxaemia in the newborn. Tolazoline, pulmonary vasodilator of choice here, was used to treat this syndrome in 13 newborns. Therapeutic indications, precautions and possible side-effects are discussed.

[Fast and accurate method for theophylline analysis in preterm babies using gas chromatography and nitrogen selective detector (NFID) (author's transl)].

The combined utilization of (a) a weak polar OV-1 phase, (b) an on-column methylation using a methylating agent commercially available, (c) a nitrogen selective detector (NFID) and (d) a small volume of sample, allows the development of a fast (less than 20 min) and accurate method for theophylline analysis in preterm babies. With 50 microliter of capillary whole blood sample, its limit of sensitivity was 0.5 microgram/ml of theophylline. This method is most desirable for theophylline monitoring in treating apnea of premature infants.

Echohysterosalpingography: new diagnostic possibilities with S HU 450 Echovist.

The use of a new sonography contrast medium (Echovist Shering SH U 450) is evaluated in this paper. This new method offers the possibility of investigating both the uterine cavity and the tubes representing an easy screening method for infertility and other gynecological problems. The possibility of examining the patient using ultrasound gives us the possibility of avoiding X-ray exposure (necessary for HSG) or general anaesthesia (required for laparoscopy). Our data is still insufficient in order to make a definite conclusion on the absolute replacement of HSG and, sometime, of laparoscopy with this method.
