RESUMO
We report a case of prenatal diagnosis of thrombosis of the torcular Herophili. Detection at 22 weeks' gestation by ultrasound scan of an anechoic mass located immediately above the tentorium led to magnetic resonance imaging (MRI) being performed at 28 weeks which established the diagnosis of an isolated thrombosis of the torcular Herophili. MRI remained stable throughout pregnancy, and postnatal MRI confirmed the diagnosis at 2.5 months of age. The child is now 16 months old and developing normally.

We report three pregnancies where enlarged nuchal translucency was discovered at the first trimester transvaginal ultrasound examination; congenital heart disease developed later. Two cases of hypoplastic left heart were diagnosed prenatally at the mid-trimester sonographic examination. The pregnancies were terminated. In the third case, a supravalvular pulmonary stenosis was discovered on the second day of life. Further investigations demonstrated a mutation on the elastin locus, thus confirming the diagnosis of Williams-Beuren syndrome. The role of nuchal translucency as a risk marker for congenital heart disease is discussed.

The authors analysed 100 sperm samples from asymptomatic patients and compared them with a control series of sperm donors who had been considered fertile by CECOS of Marseille or from men whose partners had conceived. They found Chlamydia trachomatis in 29% of the cases studied (P less than 0.0001). They found an abnormal movement of the sperm which they called the "Jerk Phenomenon" and which was found in 76% of cases (P less than 0.0001), where the culture for Chlamydia trachomatis was positive. This correlation does not change in association with other germs. Micro-cinematographic studies confirm the asthenospermic character of this movement. Since the sperm movements become normal after treatment with tetracycline one must consider that Chlamydia trachomatis can be an etiological agent for infertility in men.

The study was carried out in two different hospital centres on a series of 55 women who had ectopic pregnancies compared with 2 control groups. The study concerned taking samples from cells in the pelvis to culture for Chlamydia trachomatis and to estimate the levels of anti-Chlamydia antibodies. The cultures were positive in 30% of the cases and the serology was positive in 52% of the cases. This difference is significant when compared with the control groups (p less than 0.001). There was no significant statistical difference as far as positive cultures were concerned between the groups of women who had or had not had previous tubal infertility or a history of salpingitis. It seems that Chlamydia trachomatis can itself therefore be a direct cause for the development of an ectopic pregnancy.
