[Prenatal ultrasound measurement of the interorbital distance. Method of recognizing lesser degrees of holoprosencephaly].

The antenatal diagnosis of holoprosencephaly seems to need study of the interhemispheric fissure which may or not be complete in lesser degrees of that disease, but also measuring of interorbital distance (I.O.D.) and I.O.D./B.P.D. (biparietal diameter) ratio. The two last parameters show the constant hypotelorism. These measures may be useful in all fetal congenital deformities which include facial dysmorphy with modification of the interorbital distance.

[Incidence of birth injury in full term newborns in the last 5 years at Port Royal Maternity Hospital (author's transl)].

The incidence of birth injury in full term neonates during the last 5 years at Port Royal Maternity Hospital has been determined. Cerebral symptoms were classified in three grades; mild, moderate and severe. The study was concerned with gestational and obstetric causes of cerebral damage. Babies with malformations, metabolic disorders and infections were excluded. During the study the incidence of intra-partum deaths and still births was low, 2 to 2.5 per thousand births, and did not alter but there was a statistically significant reduction in the number of babies in the moderate and mildly affected groups. This may be due to improved obstetric practice. From 1974 to 1978 the incidence of fetal heart monitoring increased from 20 to 60 percent and since early 1977 amnioscopy has been performed in every woman admitted. The incidence of cerebral symptoms may be an important method of assessing the quality of obstetric care. Serious accidents are becoming rare and therefore the incidence of mild or moderate cerebral symptoms is likely to be a better indicator of good obstetric care. In full term infants perinatal factors are infrequently the cause of brain damage.

[A method of fetal surveillance in utero: active movements count (author's transl)].

The authors have investigated the method introduced by Sadovsky for analysing fetal activity in which the woman counted her fetal movements in accordance with a time schedule. The counts were performed for three periods of 30 minutes, each day, at 9 a.m., 5 p.m. and 9 p.m. Thirty minutes was the time chosen for each period because, after this time, most patients became tired and subsequent recordings became unreliable. After careful instruction, the patient was provided with a digital counter. The total number of movements counted was recorded on a special data form. This method was found to be useful for the assessment of chronic fetal distress in disturbances of the feto-placental unit, particularly in hypertension. Normal fetal movements in high-risk pregnancies are an indication of fetal well-being. Decreased fetal movements may be an indication of chronic fetal asphyxia. In this case, cardiotocography has to be undertaken. We intend to make a prospective study to elucidate the normal pattern of fetal activity throughout pregnancy, the factors which affect the fetal movements and the prognostic significance of their variations.

[Tubal repermeabilisation after sterilisation. Techniques and results (author's transl)].

Requests for repermeabilisation surgery, previously rare, are becoming more common. The indications for reparative surgery are analysed. Microsurgery is possible when the length of the remaining tube us adequate, more than 5 cm, and the ampulla undamaged. It is made difficult when the initial sterilisation procedure has destroyed too long a segment of the tube: electrocoagulation, resection of a long loop of tube. It is impossible when the ampulla and the adjacent portion of the tube have been damaged. Microsurgical techniques certainly improve the results of reparative surgery. After end-to-end anastomosis of the medial half of the tube, 60 to 75% of pregnancies going to term are obtained, and more than 90% secondary permeability. New methods for surgical sterilisation such as clips or rings should make it possible to achieve even better results in the future.
