[In vitro fertilization and smoking: use of urinary cotinine and expired air carbon monoxide measurements].

OBJECTIVE: To study the correlation between expired air carbon (EACO) and urinary cotinine, and to determine the impact of tobacco smoking on in vitro fertilization (IVF) results. PATIENTS AND METHODS: We studied prospectively 221 patients in our ART center from October 2002 to October 2004: 51 active smokers, 85 passive smokers, and 85 non-smokers. Patients were classified into active, passive smokers, or non-smokers, based on a questionnaire. We measured urinary cotinine and EACO on the embryo transfer day and we recorded the IVF parameters. RESULTS: Two hundred and twenty-one patients were included. We observed a 17.2% reduction of estradiolemy (P=0.05), a 1.5% reduction of pregnancies (NS), a 7.8% reduction of infants born alive (NS), a 28.5% reduction of twin pregnancies (P=0.06), as well as a 10% increase of miscarriages (NS) in the active smokers in comparison with non-smokers (the same trends were observed between active and passive smokers). EACO and urinary cotinine were well correlated. There was a negative correlation between estradiolemy and urinary cotinine (R=-0.15, P=0.02). DISCUSSION AND CONCLUSION: Tobacco smoking intensity may be dilatory on IVF results. There is a high correlation between EACO and urinary cotinine. Other larger studies would probably obtain results more statistically significant.

[Multislice helical CT: principles, applications].

The real innovation of multislice helical CT is its technology of detectors. These detectors may be isotropic, anisotropic or hybrid according to the manufacturers. Whatever the concept in terms of geometric resolution or evolutivity, all of them provide similar implementations and image quality. Data transfer and computer performances are as much as eight times higher than those of single slice CTs. Large pitches are routinely available. The speed of workstation softwares has been dramatically increased. Acquisition times have also been reduced like on new single-detector CTs. According to the machine, a 360 degrees rotation of the tube is obtained in 0.5 to 0.8 sec. Evolution more than revolution, there is need for further clinical expertise to know whether this new technology is able to substitute for other imaging modalities. In the meantime, what is sure is that it will generate new clinical applications.

[Sub-capsular hematoma of the liver during pregnancy: a case report].

A sub-capsular haematoma of the liver is a rare but very serious complication of pregnancy. We report a case of a primipara whose pregnancy was first complicated by hypertension, then by a haematoma of the liver at the 28th week of amenorrhoea. It was diagnosed because of the clinical symptoms associated with the hypertension and a pain in the right hypochondrium and nausea. The diagnosis of haematoma of the liver was made before rupture and confirmed by ultrasound of the liver and by tomodensitometry made it possible to avoid operating on the liver during the laparotomy that was carried out to terminate the pregnancy. Regular X-ray follow-ups showed that the lesion had regressed in six months. MRI investigation of the parenchyma of the liver showed no cause of the lesions. If there is even the slightest suspicion of a haematoma of the liver in pregnancy, ultrasound nowadays should be carried out because it is indispensable to make the diagnosis.
