Early cleavage: an additional predictor of high implantation rate following elective single embryo transfer.

The value of early cleavage (EC) assessment is still being debated. The aim of this prospective study was to examine the predictive value of EC assessment performed exactly 26 h after insemination by IVF or intracytoplasmic sperm injection (ICSI) in a programme of elective single embryo transfer (SET) performed at day 2. If day 2 scoring demonstrated several embryos with high implantation potential, an EC embryo was transferred preferentially. EC was assessed only during normal laboratory hours so that there were two groups: EC assessed, and EC not assessed, the latter being the control. A total of 277 elective SET were performed in women under 37 years undergoing their first IVF or ICSI cycle (mean age 30.5 years, range 21-37). The overall clinical and ongoing pregnancy rates were 40.1% (111/277) and 32.9% (91/277) respectively. Significantly higher overall clinical and ongoing pregnancy rates were obtained after transfer of an EC embryo than a non-EC embryo: 49.4 versus 33.3% (P < 0.05) and 42.4 versus 25.9% (P < 0.02) respectively. However there was no significant difference between the EC assessed and control groups: 40.4 versus 39.3% and 33.2 versus 32.1 respectively. These findings confirm the value of EC assessment for selection of embryos with high implantation potential.

[Elective single embryo transfer: a justified policy for selected patients].

OBJECTIVE: Prevention of twin pregnancies using elective Single Embryo Transfer (e-SET) is now considered by many Assisted Reproductive Techniques teams as a necessity. The aim of this study was to assess the efficacy of e-SET in a prospective manner in a selective population of patients using Take Home Baby Rate per couple as principal parameter. PATIENTS AND METHODS: This prospective study was conducted from January 2003 to December 2004. Elective Single Embryo was proposed to women above 37 years in their first IVF or ICSI attempt. It was then performed only in cases when at least one embryo with high implantation potential (score-4 embryo in our embryo scoring) was obtained for transfer and one more (score-3 or score-4 embryo) was available for freezing. RESULTS: e-SET was proposed and accepted in 225 couples (25% of eligible couples and 7.8% of total population) and was possible in 96 of these). Two embryos were transferred in all other eligible patients (Double Embryo Transfer group=DET). Cumulative delivery rate after fresh embryo transfers and, if necessary, after frozen-thawed embryo transfers were 39.5% per couple e-SET group and 41.7% in DET group (NS). On the other hand, the percentage of twin pregnancies was significantly different between the two groups (2.6% vs 26.6% respectively; P<0.01). DISCUSSION AND CONCLUSION: In women younger than 37 years in their first IVF/ICSI attempt, the elective transfer of only one embryo with high implantation potential strongly allowed to avoid twin pregnancies without any significant delivery rate decrease. This transfer policy is particularly efficient in laboratories displaying good results in their embryo freezing program.

Crude cumulative delivery rate following ICSI using intentionally frozen-thawed testicular spermatozoa in 51 men with non-obstructive azoospermia.

This prospective study evaluated the crude cumulative delivery rate following delayed intracytoplasmic sperm injection (ICSI) using spermatozoa recovered by testicular extraction (TESE) and intentionally frozen in men with non-obstructive azoospermia (NOA). This procedure can be termed 'cryoTESE-ICSI'. This study involved a series of 118 patients who underwent testicular biopsy for diagnosis of NOA in the period from January 1998 to December 2002. Testicular histology confirmed the diagnosis of NOA. Testicular parenchyma was obtained surgically from both testicles under general anaesthesia. Cryopreservation of spermatozoa was performed in 51 of 118 patients (43%). Ninety-nine delayed ICSI procedures were performed. Frozen-thawed suspensions were used in all cycles. Application of pentoxifylline was required to stimulate spermatozoa in 52% of cases. Fertilization, embryo transfer, and ongoing pregnancy rates were 60, 98 and 29% respectively. The crude cumulative delivery rate was 49% after two cycles and 57% after four cycles. A total of 39 healthy children were born in 29 deliveries. Thus, cryoTESE-ICSI is an effective procedure for routine use in patients with NOA. The main advantages of cryoTESE-ICSI are to (i) avoid repeated surgical biopsy, (ii) ensure the availability of spermatozoa when the ovarian stimulation cycle is begun, and (iii) allow programmed biopsy and therefore dissociate it from ICSI.

Glutathione S-transferase M1 gene polymorphism and susceptibility to endometriosis in a French population.

Endometriosis is a multifactorial disease with possible genetic predisposition and involvement of environmental factors in its pathogenesis. The genetic polymorphism of glutathione S-transferase M1 (GSTM1) gene, which codes for glutathione S-transferase 1, class mu foreign compound conjugating enzyme of phase II detoxification system, was studied by polymerase chain reaction from the blood spots in patients with different stages of endometriosis (n = 50) and in controls (n = 72) of French origin. A total of 86.0% of patients appeared to lack GSTM1 enzyme activity due to the presence of an extended deletion (GSTM1 0/0 genotype), compared with 45.8% in a control group (P < 0.0001), which was consistent with the frequency of GSTM1 deletion in French population. Moreover, the distribution of GSTM1-active genotypes was significantly different in patients and controls (P < 0.0001), as no patient with GSTM1A/B genotype, which is correlated with the highest activity of GSTM1 enzyme, has been found so far (18.1% in a control group). The unusually high frequency of homozygotes for the GSTM1 gene deletion among patients with endometriosis suggests a possible contribution of environmental toxins in the pathogenesis of this disease due to the absence or low activity of GSTM1 enzyme.

Mother-to-child transmission of human T-cell lymphotropic virus types I and II (HTLV-I/II) in Gabon: a prospective follow-up of 4 years.

SUMMARY: For 4 years. we determined the mode and risk of mother-to-child transmission of HTLV-I in a prospective cohort of 34 children born to seropositive mothers in Franceville, Gabon. We also determined the prevalence of antibodies to HTLV-I/II in siblings born to seropositive mothers. Antibodies to HTLV-I/II were detected by Western blot, and the proviral DNA was detected by the polymerase chain reaction (PCR). The risk of seroconversion to anti-HTLV-I for the 4 years of follow-up was 17.5 percent. Anti-HTLV-I/II and proviral DNA were only detected after age 18 months. We observed a seroprevalence rate of 15 percent among the siblings born to HTLV-I/II seropositive mothers. Furthermore, we report a case of mother-to-child transmission of HTLV-II infection in a population of HTLV-II-infected pregnant women that is emerging in Gabon. The lack of detection of HTLV-I/II proviral DNA in cord blood and amniotic fluid and, furthermore, the late seroconversion observed in the children indirectly indicate that mother-to-child transmission occurred postnatally, probably through breast milk.

Laparoscopic management of adnexal abscesses: consequences for fertility.

OBJECTIVE: To study fertility of patients with adnexal abscesses treated by laparoscopy, antibiotic therapy, and second-look laparoscopy. DESIGN: A retrospective clinical study. SETTING: Department of Obstetrics Gynecology and Reproductive Medicine, University of Auvergne, University Hospital of Clermont Ferrand, France. PATIENT(S): Thirty-nine patients treated for adnexal abscesses between January 1983 and December 1992. INTERVENTION(S): Laparoscopic drainage of adnexal abscesses was performed in all patients; 35 patients underwent a second laparoscopy 3 to 6 months later. MAIN OUTCOME MEASURE(S): Immediate and long-term clinical results, anatomical data obtained at second-look laparoscopy, spontaneous fertility. RESULT(S): No immediate reoperation was necessary within the first 2 months after the initial laparoscopic surgery. At second-look laparoscopy, an adhesiolysis was necessary in all cases. A distal tuboplasty was performed in 17 patients and 6 patients were referred to IVF-ET. Subsequently, 12 of 19 patients not using any contraception obtained a spontaneous intrauterine pregnancy (63%). CONCLUSION(S): This study confirms that laparoscopic surgery is a safe and efficient technique for treating adnexal abscesses. Anatomical results observed at second-look laparoscopy suggest that this second surgical step is essential for patients desiring future pregnancy.

Future endoscopic trends in gynecological oncology.

Using technological progress, laparoscopic lymphadenectomy is becoming the standard for staging of pelvic cancer. In the same way more extensive procedures such as para-aortic lymph nodes dissection and radical hysterectomy have been demonstrated to be feasible by laparoscopy. This new approach appears very promising. In the future, because of its well known advantages, laparoscopic surgery may appear as a way to decrease the consequences of oncologic treatments in patients with low risks tumors and to propose more aggressive treatments of patients with bad prognosis tumors.

[Treatment of endometrial clinical stage I adenocarcinoma by laparoscopic surgery. Seventeen cases].

AIM: Study and follow-up of laparoscopic surgical treatment of endometrial cancer, clinical stage I. METHOD AND MATERIALS: This retrospective study covering the period 01 February 1990 to 31 January 1994 on 17 patients presenting with endometrial cancer, clinical stage I, that is, 35.4% of endometrial cancers operated in our department during that period, and for which laparoscopy was the first step in surgical treatment. RESULTS: Of the 17 cancers assessed by laparoscopy, 12 were also operated by laparoscopy. Conversion to laparotomy concerned 5 cases (29.4%): one case of postoperative adhesions, 2 cases of laparoscopic complications (cardiac rhythm problems, sub cutaneous emphysema), 2 cases of peritoneal granulations giving rise to suspicious of stage III. The mean age of the patients operated via laparoscopy was 59.9 years (extremes: 34-74). Their weight varied from 52 to 94 kg with a mean of 68.1 kg. Two endoscopic surgical complications arose (one bladder injury and one cervico-vaginal bleeding), but did not require conversion to laparotomy. No postoperative complications were noted. The average follow-up for these patients treated by endoscopy is 22.3 months. There was regrettably one early recurrence of the disease 7 months postoperatively. CONCLUSION: Laparoscopic surgery can be used to treat clinical stage I cases of endometrial cancer. This surgical approach must be used only for favourable cases and is reserved for teams trained in endoscopic and cancer surgery.

[Laparoscopic treatment of adnexal abscesses. A series of 39 patients].

OBJECTIVE: Evaluate short- and long-term follow-up of patients treated by laparoscopy and antibiotherapy for tubo-ovarian abscess. METHODS: We report a retrospective study of 39 patients treated from January 1983 to December 1992. Clinical files were examined and a questionnaire was mailed to patients. RESULTS: None of the patients needed to be reoperated for failure of the first laparoscopic treatment. A laparoscopic control after 3 month was done in 35 cases, which allowed complete adhesiolysis in every patients. We performed distal tubal surgery in 17 patients at that time and oriented 6 patients directly towards IVF. Subsequent fertility, in 19 patients followed without contraception, demonstrated a rate of spontaneous intra-uterine pregnancy of 63%. CONCLUSION: This study confirms that laparoscopy remains the technique of choice in initial management of adnexal abscesses.

[Ploidy analysis in a case of ovarian small cell carcinoma with hypercalcemia].

The authors studied DNA content in a case of small cell carcinoma with hypercalcemia. This tumor exhibited typical clinical, histological, immuno-histochemical, ultrastructural and biological patterns. DNA content was measured both by flow and image cytometry performed on unfixed tumoral samples. The proliferation index was 10%. These results are similar to those of the literature obtained retrospectively from 10% formalin fixed tissues. The DNA content is a clue to distinguish this entity from other small cell carcinomas of the ovary because immunohistochemical findings are not always informative. The diagnosis of small cell carcinoma of hypercalcemic type should be questioned if DNA content is abnormal.

Introduction of gynecologic endoscopic surgery in an African setting.

The new operative endoscopic techniques have been fully tried in the industrialized world and have spread to all surgical specialities. These new technologies present an obvious advantage for certain gynecologic pathologies which are particularly common in Africa. For pelvic inflammatory diseases, ectopic pregnancies and tubal sterility, laparoscopic surgery enables an initial assessment of disease, a less traumatic treatment and therefore a better long-term prognosis for fertility and reduced postoperative morbidity. Recently, an operative endoscopic unit performing laparoscopic surgery and endoscopic resections was created at the Centre Hospitalo-Universitaire de Yaoundé in Cameroon. This facility is the result of close collaboration between the University of Yaoundé and the University Hospital of Clermont-Ferrand. This operative endoscopic unit has been functioning since April 1992. The authors discuss the difficulties involved in such projects, such as initial investment, maintenance of equipment and in particular training of the surgical team.

Laparoscopic Management of Suspicious Adnexal Masses

After our initial experience with 757 patients, we have extended our indications for laparoscopy to suspicious adnexal masses. Twenty of 29 ovarian cancers surgically treated since December 1991 were first evaluated by laparoscopy. In all, 321 patients were evaluated by laparoscopy in 1992 and 1993, including 145 women with an ultrasonographically suspicious mass (45.7%). At laparoscopy, 52 masses were diagnosed as suspicious, including 20 cases of malignant ovarian tumors. Sixteen patients were treated by laparotomy (5%), including 11 women with cancer, 2 with teratomas diagnosed as suspicious, and 3 with benign masses that could not be treated endoscopically (0.9%). In cancer treated by laparotomy, staging, including the assessment of the upper abdomen, was begun laparoscopically. When a cancer was managed laparoscopically, an early second look laparoscopy was performed routinely. Since many laparotomies may be avoided, laparoscopic surgery is promising in the management of suspicious adnexal masses. However, from two cases of tumor dissemination, we conclude that this management should follow strict guidelines and needs to be further evaluated.

Incidence of ectopic pregnancy. First results of a population-based register in France.

A population-based register of ectopic pregnancy was established in 1992 for two French departments, with the primary aim of monitoring the trend in ectopic pregnancy over a prolonged period. In this paper, data collected during the first year of registration (1992) are analysed. The rate of ectopic pregnancy was 20.2 per 1000 live births, 15.8 per 1000 reported pregnancies and 9.5 per 10,000 women aged 15-44 years. The ectopic pregnancy rate per 1000 live births increased steeply after the age of 30 years and especially after the age of 35 years, whereas rates per 10,000 women of reproductive age steadily increased until the age of 35 years and decreased thereafter. The rates of ectopic pregnancy were lower in spring and summer than autumn and winter. These results are discussed and comparisons with similar studies conducted in the USA and Scandinavia are attempted.

[Failure factors in endometrial resection. 196 cases].

OBJECTIVE: Study of factors affecting risk of failure after hysteroscopic endometrial resection. METHODOLOGY: A retrospective study of 196 patients treated by hysteroscopic endometrial resection for abnormal uterine bleeding from January 1989 to December 1990. A survey was conducted in February 1993 to study the results of these interventions with a particular attention paid to the failure cases. RESULTS: The survey revealed a satisfaction rate of 82%. Persistence of abnormal bleeding after resection was the most common problem reported, although in 32% of these cases the bleeding began after a period of at least 2 years in remission. A more complete clinical and pathological study was performed in 22 cases of hysterectomy for failure after resection. Enlarged uterine size and presence of adenomyosis increase significantly the failure rates. CONCLUSION: After 2 or 4 years of follow-up, the results are satisfactory but the existence of late recurrences showed that it will be necessary to have long term reviews. Two major risk factors are enlarged uterine size and the presence of adenomyosis.

[Ovarian abscess. A case of a dermoid cyst with a secondary infection].

The authors report a case of an ovarian abscess presenting as acute sciatica with pyrexia in a 36-years-old woman with an intrauterine contraceptive device. Imaging (plain X-ray of abdomen and CT scan) was clear-cut, showing an air pocket as a result of abscess formation and dental calcifications which enabled a preoperative diagnosis of dermoid cyst. The outcome was successful following appropriate surgical treatment and unilateral tubo-oophorectomy.

[The benefits and risks of laparoscopic surgery].

The advantages of laparoscopic surgery in comparison to those of conventional surgery are mainly due to the very low rates of postoperative infections and adhesions and due to the aesthetic nature of this type of surgery. Endoscopy enables a thorough search of lesions which can then be treated in a more conservative manner. The short hospital stay and rapid postoperative recovery are two key advantages of endoscopic surgery. Complications at endoscopic surgery mainly occur if the safety measures are not strictly followed, due to improper choice and use of instruments (eg. old instruments), an antecedent laparotomy and also depend upon the type of surgery performed. It should be noted that the introduction of the trocar is not a simple affair, that non-recognition of complications is not infrequent and that the incidence of complications is directly proportional to the experience of the operator.
