[Fetal lung maturity and skin maturity: 2 distinct concepts and the clinical significance of their differences].
The maturation of the fetal lungs, that is to say the adequate production of surfactant in the fetal alveoli, as it is well known reaches to its end about the 35.-36th week of gestation. Even more closely to the date of delivery, about the 37.-38th week of gestation, the maturation of the fetal skin takes place, so to say the detachment of the Vernix caseosa from the fetal skin into the amniotic fluid. The above mentioned means that the children with "mature skin" should have mature lungs too, so that those children have about nothing to fear from the RDS. That can be proved by the comparison of the values which were measured in 38 cases of the L/S Ratio (as a criterion of the lung-maturity), to those of the turbidity of the amniotic fluid and average quantities of the keratinocytes of the amniotic fluid cell population (as a criterion of the skin-maturity); that observation becomes stronger with the comparison of all those values to a Vernix-Score, which can be completed after delivery.

Ovarian hyperstimulation syndrome and heterotopic pregnancy after IVF.
We report a case of Severe OHSS combined with Heterotopic pregnancy. During the treatment of OHSS the patient underwent transvaginal paracentesis for the ascites but no sign of blood was noticed into the fluid. The ultrasound control in the 8th week had shown a normal intrauterine pregnancy without any suspicion for heterotopic pregnancy. The diagnosis for heterotopic pregnancy became possible at 10 Weeks of gestation by Ultrasound. Laparotomy with partial tubal resection was performed. The intrauterine pregnancy is still ongoing without complications.

Laparoscopic tubal surgery. A retrospective comparative study of open microsurgery versus laparoscopic surgery.
The aim of this study is to compare retrospectively the outcome of patients that underwent tubal surgery by laparotomy or laparoscopy by the same surgeon Thirty two women that presented with distal tubal obstruction were treated by laparoscopic tubal surgery and 38 by laparotomy and microsurgery. Patients were equally matched for age, duration of infertility and severity of disease. In all cases there were no injuries to adjacent groups and no additional surgery was needed. The duration of surgery was 35-60 min for laparoscopy and 70-120 min for laparotomy and mean duration of hospital stay was 2 and 7 days respectively. Of the 32 cases that underwent laparoscopic surgery 10 had intrauterine pregnancies (31.25%) and 2 ectopic (6.2%). Conversely 11 (28.9%) of the 38 cases with tubal microsurgery resulted in intrauterine pregnancy and 4 (10.5%) in ectopic. Our results suggest that laparoscopic tubal surgery is the method of choice for the treatment of distal tubal obstruction.

The echoguide embryo transfer maximizes the IVF results.
The performance of two different methods of embryo transfer for IVF has been evaluated in 132 consecutive embryo transfers. Thirty Eight pregnancies were achieved, corresponding to a pregnancy rate of 28.7% of all embryos transfers. The embryo transfer under ultrasound control was used in 61 cases of our study whereas 71 cases were performed with the "clinical feel" method without ultrasound control. The echoguide embryo transfer procedure yielded a significantly higher pregnancy rate than the blind method (36.06% versus 22.6%). The mean number of embryos transferred per attempt was similar in the two groups (3.1 +/- 0.1 and 3.0 +/- 0.1) as was the quality. The randomized comparative study will continue in order to get more data.
