Could aspiration of the Graafian follicle cause luteal phase deficiency?

Luteal phase quality was evaluated in 32 patients wih nonstimulated cycles after laparoscopic oocyte recovery for in vitro fertilization. A luteal phase deficiency occurred in two cases (6.2%), the mean duration of the luteal phase was 13.5 +/- 1.3 days in 30 patients, and two patients developed amenorrhea of 23 and 43 days respectively after laparoscopy in spite of normal progesterone values 7 and 9 days after oocyte recovery. Six embryo transfers were performed after fertilization and regular cleavage of the obtained oocytes. No pregnancy resulted from the embryo transfers, although the patients had apparently normal luteal phases. In one patient there was a transient beta-subunit human chorionic gonadotropin (beta-hCG) elevation in serum. Luteal phase deficiency should not be main cause of a nonsuccessful embryo transfer. However, a prophylactic luteal phase support after oocyte recovery and embryo transfer in nonstimulated cycles is proposed.

[Ability to work following radical surgery for cervix carcinoma].

During follow-up examinations of 74 women after radical hysterectomy the time interval between the end of treatment and the start of the subsequent professional activity has been examined. 34.1% of the patients started to work after 3 months, 46.8% worked within 6 months, 72.3% within 12, and 87.2% within 18 months. 61.7% of the women worked in the same job as before their operation, 29.8% started in an new job. The results are in full agreement with the personal opinion of 73.1% of all women who consider a space of up to 6-7 months optimal for their rehabilitation, up to 3 months was ideal for not less than 44.7%. A sick leave of up to 6 months was considered essential and helpful by 51% of all women. In 74.5% of all cases the date for the start in their professional work was in agreement with the personal plan of the women. It is concluded from these results that 3 months after treatment the problem of professional work should be discussed with the patient, provided that she is free of recurrence. This time interval is optimal from the patient's standpoint.

[The clinical efficacy of the copper-containing intrauterine devices Nova T and Copper-T-200 Ag in a randomized study (author's transl)].

In a randomized study the clinical efficacy of the traditional intrauterine device. Copper-T-200 Ag was compared with the recently developed model Nova T. Altogether 93 women with regular menstrual cycles were examined; 45 women had a Nova T inserted and 48 the traditional Copper-T-200 Ag. The biosocial data of the women in the two groups did not differ from one another. No pregnancies occurred in either group within the first 12 months. Expulsion occurred in 2 women with Nova T and removal of the device had to be undertaken for bleeding and pain in 3 women with a Copper-T-200 Ag. At 12 months the two models did not differ in the number of recorded incidents. The reliability of randomized studies is discussed, as well as problems arising from the fact that the mode of insertion is not identical with both devices and requires practice in the case of the new model.

[Spontaneous pneumothorax and its treatment].

It is reported on 111 cases with 123 episodes of spontaneous pneumothorax. Pathological lung changes were found only in 47% of the cases. The percentage of acute lung tuberculosis is minimal. Adequate therapy is the early intercostal constant sucking drainage. Very early thoracotomy should be performed if results of drainage therapy is unsatisfactory or serious complications occur. Pneumothorax after Bülau-drainage recurs in about 16% of the cases. The secure method for prevention of recurrence is thoracotomy.

Results of laparoscopic recovery of preovulatory human oocytes from nonstimulated ovaries in an ongoing in vitro fertilization program.

The technique and results of 50 laparoscopies performed on sterility patients to obtain mature oocytes from Graafian follicles with a view to carrying out in vitro fertilization are described. In 32% of all laparoscopies and in 52% of all punctured follicles it proved possible to obtain a mature oocyte. Different diameters of puncture needles as well as different suction intensities are compared. As a result of increasing experience and improved technique, the exact time for the intervention was correctly determined in 92% of cases. The recovery rate for oocytes was also increased to 58% with respect to laparoscopies carried out.

Disseminated infection with mycobacterium chelonei in a haemodialysis patient.

M. chelonei ssp. chelonei was isolated over a period of 5 months from abscesses on various sites of hands and feet of a patient on maintenance dialysis. The organism was resistant in vitro to a greater number of antimicrobials and treatment in turn with gentamicin, vancomycin, erythromycin, doxycycline and co-trimoxazole had to be supplemented by surgical drainage of abscesses. Examination of the dialysis circuit revealed repeatedly the presence of M. chelonei and M. fortuitum in the water softener resin and other sites. The significance of this finding is discussed.

[The position of the IUD and intrauterine pregnancies].

In 59 women who became pregnant with an IUD the position of the device was controlled by ultrasound. Before the 9th week of pregnancy the device was located in 40 women (78.4%) in the cervix or in the isthmic region of the uterus. In 11 cases the IUD was in correct position. 8 women had a pregnancy of more than 9 weeks and were not included in the study as the gestational sac could have influenced the IUD position. The possibility of regular control of the IUD position by ultrasound is discussed in order to reduce the failure rate of this contraceptive method.

[Technique of obtaining mature oocytes via laparoscopy for in-vitro fertilisation (author's transl)].

Technique and results of 50 laparoscopies performed on sterility patients to obtain mature oocytes from Graafian follicles to carry out in vitro fertilisation, are reported. In 32% of all laparoscopies and in 52% of all punctured follicles a mature oocyte could be obtained. Different diameters of puncture needles as well as different suction intensities are compared. It is mentioned that through increasing experience and improved technique the exact time for the intervention has been correctly determined in 92%. The recovery-rate for oocytes also could be increased to 58%. A further improvement in this important initial step to a successful in vitro fertilisation program is feasible.

[Control of IUD-position (author's transl)].

The correct position of an IUD in the uterine cavity is essential for the effectiveness of the method. Ultrasound examination of the thickness of the anterior and posterior wall of the uterus were carried out and their relation to a correct position of the IUD calculated. It was found that the position of the IUD is correct, if the distance between fundus and the cranial end of the IUD does not exceed the thickness of the uterine wall by more than one-third; i. e. in all 4/3 of the thickness. The correlation between the ultrasound results of length, version and flexion of the uterus and complaints and side-effects like bleeding and pain are discussed, especially if the IUD is not in correct position.

[Human in vitro fertilisation and embryotransfer: first results at the 2nd department of obstetrics and gynaecology, university of vienna (author's transl)].

Methods and Results of human in vitro fertilisation at the 2nd Department of Obstetrics and Gynaecology, University of Vienna are reported. Applying preparations of media and culture techniques according to Edwards et al. no satisfactory results could be achieved: only 3 out of 11 preovulatory oocytes were fertilised, no cleavages occurred. Using modified Ham's F 10 medium according to Lopata et al. fertilisation could be observed in 60% as well as regular cleavages in 40%. 5 Embryotransfers have been performed in the 8 cell or in the 16 cell stage respectively. No implantation occurred in 4 of these, in one case evidence for a transient implantation could be proved by an increased activity of SP1 and HCG beta. In this case obviously postimplantation death occurred resulting in a bleeding 16 days after oocyte recovery. Possible reasons for failures in fertilisation and cleavage as well as possibilities for improving the rate of reimplantation are discussed.
