The authors report a case of chickenpox exposure during the first three months of pregnancy. Ultrasonographic monitoring of the fetus revealed signs of fetal infection starting from 32 weeks of amenorrhea (hepatomegaly, ascites, pleural effusion) but clinical examination of the child at birth showed nothing abnormal. The diagnosis was confirmed by the development of herpes zoster in the child after birth. The difficulty of determining a fetal prognosis during pregnancy is emphasised.

The choice of method of contraception in cardiac patients is often peremptory, as combined oestrogen-progesterone preparations and intra uterine devices are often contraindicated. A pure progesterone mini-pill, lynoestrenol (500 microgram) has been used in our department for several years, and would appear to be a possible solution. Its daily, uninterrupted administration for 6 to 30 months in 40 cardiac patients, many considered to be high risk cases (28 cases), has confirmed its contraceptive action: totally effective, excellent reversibility and satisfactory acceptability despite definite menstrual changes. Above all, it was almost totally innocuous, an essential factor in cardiac patients. No haemodynamic, hypersensitive or thromboembolic side effects were observed in any pateint. No changes were observed in glucose or lipid metabolism, hepatic function or blood coagulation after 3 to 6 months, in 6 to 14 patients at high risk. Platelet aggregation, factors II, V, VII and X, fibrinogen and anti thrombin II were normal. Although this is a small series of patients, the use of microdosage lynoestrenol seems an acceptable method of oral contraception for cardiac patients, providing they collaborate and are closely followed up from the cardiac point of view.

Pelvic actinomycosis is uncommon and usually represents a complication of an intrauterine device (IUD). This organism is very difficult to culture, and most actinomyces is actually identified by histologic features in pathologic specimens or by cytologic features on Papanicolaou smears. A specific fluorescent antibody stain is also available. Tubo ovarian abscess is usually polymicrobial with a preponderance of anaerobic organisms and the exact role of actinomyces in abscess formation remains unclear.
