[Persistent hyperbilirubinemia after intrauterine intraperitoneal transfusions in 4 newborn infants. Role of intraperitoneal red cells present at birth].

Four neonates who had undergone intra-uterine peritoneal blood transfusions for Rhesus disease and hydrops fetalis presented, during the first days of life, with intractable hyperbilirubinemia in spite of multiple exchange transfusions. The hyperbilirubinemia was due to delayed absorption and hemolysis of peritoneal red cells. This unusual complication can be successfully managed with peritoneal lavage which should be performed when the antenatal history is contributive for low absorption of transfused blood.

Transvaginal sonographically controlled follicle puncture for oocyte retrieval.

Transvaginal sonographically guided follicle aspiration under local anesthesia was performed on more than 100 patients and compared favorably with the other techniques that have been proposed to retrieve oocytes for in vitro fertilization. Sonography employs a sector scanner placed on the abdomen, and the needle is introduced through the posterior fornix of the vagina into the cul-de-sac and the ovary. In case of a high ovary, a transvaginal-transvesical variation may be used. The method is not painful and is easy to learn and perform. The sole adverse incidents have involved inadvertent venous puncture with no sequelae. The number and quality of recovered oocytes are good, and five normal children conceived after this method of retrieval were recently born. The technique permits substantial simplification of egg recovery for in vitro fertilization, which can now be performed in an outpatient setting without the risk and expense of laparoscopy and general anesthesia or the discomfort of transabdominal-transvesical ultrasound-guided aspiration.

[Scleroderma and pregnancy. New case and review of the literature].

A new case of the rare association of scleroderma and pregnancy is reported. The pregnancy was complicated by renal failure in the last month of gestation which was initially well controlled by anti-hypertensive therapy but then suddenly progressed to pre eclampsia with signs of foetal distress necessitating emergency caesarian section. A moderately hypotrophic child was delivered. The mother progressively recovered; diuresis and blood pressure returned to normal and the proteinuria disappeared. In the light of previously reported cases and of recent advances in our knowledge of scleroderma, especially scleroderma renal disease, the authors discuss their attitude to the management of women with scleroderma wishing to become pregnant. They review the role and place of renal biopsy in the detection of subclinical renal lesions due to the scleroderma, the presence of which would be a decisive factor in assessing the risks of pregnancy. Scleroderma renal disease is, in fact, a major contraindication to pregnancy because of the very poor foetal prognosis and the risk of maternal death due to a lethal progression of renal failure.

Intrapericardial teratoma in a newborn infant: use of fetal echocardiography.

The case of an infant with intrapericardial benign teratoma, which was suspected in utero after fetal echocardiography, is reported. This new approach permitted very early diagnosis and surgical treatment before cardipulmonary distress appeared. The tumor was excised completely, and the patient was asymptomatic three months postoperatively.

[Haemodynamic investigation in pre-eclampsia or eclampsia. Consequences of therapy (author's transl)].

Haemodynamic function was assessed in twenty patients with severe pre-eclampsia or eclampsia. In front of the earlier well-known data hypercinetic circulatory status was found with vascular resistance almost unchanged. As some investigators found two levels placental blood flow, haemodynamic status may be different in some cases. Consequences on therapy are discussed especially beta-bloquers and potential deleterious effects of anti-hypertensive treatments.

Direct fetal chromosome studies from chorionic villi.

An easy and reproducible technique for direct fetal chromosome analysis after chorionic biopsy is described. Very high colchicine concentration and rehydratation of the fixed villi are the two original points of this method.

[Fetal heart. Present investigative means].

Non invasive exploration of the fetal heart has been greatly facilitated by utilisation of high resolution echography using pulsed Doppler combined with B-scan. Investigation of the fetal heart in human medicine opens three important fields of interest. Better knowledge of fetal hemodynamics. Measurement of fetal heart function. Recognition of congenital heart disease. Acquisition of some fundamental knowledge is required for an ultrasonic approach to fetal echocardiography. Embryogenetic data lead to an understanding of the periods of vulnerability for each cardiac segment, whereas an understanding of physiology of the fetal circulation helps to explain the consequences of fetal congenital heart diseases and the methods used to evaluate fetal cardiac function. One section is devoted to the etiology of congenital heart disease. The most important cardiopathies encountered in cases of chromosomal anomalies and genetic disease as well as those due to environmental causes are presented so that the echographist may relate the examination to the clinical picture. In most instances the diagnosis of congenital heart disease is made by routine morphologic scanning of the fetal heart. Indications are given for the best orientation of the scans. All echographists should have precise knowledge of the echographic semeiology of the normal heart. When a cardiopathy or an anomaly of cardiac rhythm are recognized or suspected, the examination should be repeated with help of a cardiopediatrician so as to make an exact diagnosis and take the right decision. Study of fetal heart function is the most recent field for progress and covers in addition to the evaluation of congenital heart disease the development of new parameters allowing recognition of fetal jeopardy. Pulsed Doppler has already allowed the acquisition of interesting facts and certainly is one of the most exciting new inroads for progress in the field of fetal cardiology.
