Microsurgical treatment of tubal sterility using the CO2 laser: a reasonable alternative to IVF in cases of tubal sterility.

A retrospective analysis of women treated microsurgically using the CO2 laser in sterility treatment was performed. The aim of the study was to determine women's personal feeling about the procedure, prognostic factors, success rates, and complications. Included were 192 patients with tubal occlusions or pelvic adhesions treated by means of CO2 laser microsurgery between February 1984 and July 1992. A standardized questionnaire was used to evaluate women's procedure-related stress, extrauterine and intrauterine pregnancy rates, pregnancy complications, and postoperative complaints. In 75 cases, records and questionnaires contained sufficient data and were included for further analysis. Adhesiolysis alone, unilateral neosalpingostomy, bilateral neosalpingostomy, or new implantation was done in 7%, 52%, 33%, and 8%, respectively. In the range of 1-10, a medium degree procedure-related stress (mean 4.3, range 1-10) was expressed by the treated women. No surgery-related complications were observed. The overall pregnancy rate was 37.3%, and 10.7% were tubal pregnancies. In 26.7%, fertility surgery resulted in intrauterine pregnancies, and 21.3% of the treated women delivered living children. Three women had two consecutive pregnancies after surgery. Women with intrauterine pregnancy, extrauterine pregnancy, and no pregnancy had a mean age of 29.5 +/- 3.8, 27.3 +/- 5.3, and 32.3 +/- 4.2 years, respectively (p = NS). Mean duration of infertility before start of surgical treatment was 42.4 +/- 34.6, 41.6 +/- 25.8, and 48.8 +/- 33.2 months, respectively (p = NS). Intraabdominal instillation of streptokinase to prevent reformation of adhesions had no significant impact on tubal patency results or pregnancy rates.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of d-dimer as first marker of thrombophilia in women affected by sterility: implications in pathophysiology and diagnosis of thrombophilia induced sterility.

BACKGROUND: D-dimer is considered a marker of hypercoagulable state and of endogenous fibrinolysis, so increased d-dimer is detectable in patients affected by thrombosis. Yet, several studies showed that also infertility, in particular secondary infertility due to recurrent fetal losses, has been often related to thrombotic events, in particular in women carrying thrombotic risk factors such as inherited thrombophilia (MTHFRC677T, PTHRA20210G, Factor V Leiden polimorphisms and/or inhAfter this screening we selected 39erited protein C, protein S, AT III deficiency) or acquired thrombophilia (primary antiphospholipid syndrome, acquired protein C, protein S, AT III deficiency, drugs induced thrombophilia). However, because its high predictive negative value in case of suspected thrombosis, increased d-dimer has been often associated to subclinical thrombophilia. The aim of this study is to investigate the role of d-dimer as first marker of thrombophilia in women affected by unexplained infertility and subsequently to search the cause of increased d-dimer, such as inherited and/or acquired thrombophilia. PATIENTS AND METHODS: We selected 79 patients with unexplained primary or secondary infertility. We excluded 40 patients affected by hydrosalpinx, uterine fibroids, uterine malformations, endocrinological and immunological diseases, luteal insufficiency, cytogenetical alterations. All remaining 39 patients were tested for d-dimer and divided in two groups: the patients of group A (25 patients) showed increased plasma d-dimer, in group B were included 14 patients with normal plasma level of d-dimer. After this step all 39 patients were screened for MTHFRC677T, PTHRA20210G, Factor V Leiden polimorphisms, protein C, protein S, AT III, anticardiolipin IgM and IgG, lupus anticoagulant. In the control group were included 15 age matched women without sterility problems referred to our outpatient's section of vascular medicine for suspected deep venous thrombosis.Statistical analysis was based on chi2 test, differences were considered to be significant if p < 0.05. RESULTS: D-dimer was increased in 25/39 and 20/25 showed inherited/acquired thrombophilia while patients with normal d-dimer showed inherited/acquired thrombophilia in 7/14 (p: < 0.05, s). DISCUSSION: D-dimer is a well known marker of hypercoagulable state, in particular its high predictive negative value in case of suspected thrombosis has been recognised by several reports. Yet, increased d-dimer has been identified also for subclinical thrombophilia besides for vascular thrombosis. Our data, in fact, for the first time suggest an interesting role of d-dimer to identify women affected by unexplained primary or secondary infertility and thrombophilia. So, probably there is a role for d-dimer in these subjects for its predictive positive value. Of course, further data on large based population are needed to confirm our results, because these findings may speed up a diagnostic screening in these patients also for a good cost/effectiveness of this test.

Comparison of chloroplast DNA between photoperiod-sensitive genic male sterile (PGMS) rice Nongken58S and its derivative sterile lines.

The ORF100, ORF29-TrnC(GCA) spacer, rps16 gene intron and TrnT(UGU)-TrnL(UAA) spacer of chloroplast DNA (cpDNA) of 6 photoperiod-sensitive genic male sterile (PGMS) rice, Nongken58S and its 5 derivatives, were amplified and sequenced. According to the result of ORF100 and ORF29-TrnC(GCA) spacer analysis, the cpDNA of japonica PGMS line Nongken58S was Japonica, and among those PGMS lines derived from Nongken58S, cpDNA of japonica 7001S and 3 indica lines 1103S, Peiai64S and Guangzhan63S were that of japonica, which was in accordance with the cytoplasm pedigree provided by their breeders. But the cpDNA of indica PGMS line W6154S was that of indica, which disaccorded with the cytoplasm pedigree, so we conjectured that the breeders had used the PGMS line as the male parent. Basing on the result of sequence analysis, we found single nucleotide polymorphism in rps16 gene intron and TrnT(UGU)-TrnL(UAA) spacer of these 5 japonica PGMS lines.

[Analysis of motivation of sterilized women requesting sterilization reversal].

Within the framework of this exploratory study, 37 sterilised women wishing to be refertilised, were questioned thoroughly on what had indicated their sterilisation and why they wish to be refertilised. Assuming the existence of an interactive behaviour pattern, we concentrated on the psycho-social circumstances accompanying the definitive decision to be sterilised. Here, a critical situation in the relationship between the partners at the time of sterilisation could be established as a prognostically unfavourable factor. Accordingly, 20 of the 37 patients developed the wish to be refertilized because of a new partnership. Those who felt induced by their gynaecologist or partner to undergo sterilisation had significantly more problems in overcoming the psychological stress accompanying such an operation than those who, after repeated consultations, had enough time and possibilities to make their own decision concerning contraception. Furthermore, sterilisation due to medical indication could be suggested as another highly critical factor, especially where the gynaecologist failed to give sufficient explanation of its medical necessity. With regard to the time set for the sterilisation, the study revealed that the patient's psychological condition after the operation was significantly worse, when sterilisation was carried out immediately after a delivery or an abortion. The fact that in such cases sterilisation is often followed by an increase in psychosomatic trouble and depressive states, of mind is also confirmed by literature. The results of the study are a practical contribution towards improving preoperative consultation and coordinating the course of action to be taken where a patient has the wish to be sterilised.
