Routine CMV screening during pregnancy.

Cytomegalovirus (CMV) screening during pregnancy has been widely discussed for several years, but still no consensus has been agreed. With a number of live births of 750,000 per year in France, we would expect 7500 infected infants at birth per year (rate of congenital infection of 1%). Among infected infants at birth, the number of severely infected foetuses would be approximately 75, the number of infants with severe sequelae would be 480, 675 approximately would present with hearing loss and the number of asymptomatic infants would be 6270. Five different preventive methods for congenital CMV infection are possible: (1) Routine CMV screening at the beginning of pregnancy for primary prevention. (2) Secondary prevention by antenatal diagnosis of congenital CMV infection complications. (3) Tertiary prevention by serological testing during pregnancy. (4) Tertiary prevention by serological screening at birth. (5) Tertiary prevention: Hearing loss screening at birth. The aims of this review are to define the advantages and disadvantages of these different methods of CMV screening during pregnancy and to determine if the current available information would make systematic testing acceptable.

[Histological diagnosis after Pap smears detecting cancer or high-grade lesion of the cervix].

OBJECTIVE: The aim of the study is to analyze the histological-cytological correlations for Pap smears having detected cancer or high-grade squamous intra-epithelial lesion (HSIL) of the cervix. PATIENTS AND METHOD: The study about 311 women is retrospective. The average age is 36.4 years. Group 1 (histological diagnosis of high-grade or invasive lesion) includes 244 women (77.5%). Group 2 (histological diagnosis other than high-grade or invasive lesion) includes 37 women (11.9%) with a presumed diagnosis of HSIL. Group 3 (absence of histological follow-up) includes 30 women (9.6%) with a presumed diagnosis of HSIL. RESULTS: In group 1, the presumed cytological diagnosis is HSIL in 229 cases, squamous carcinoma in 11 cases and adenocarcinoma in two cases. In this group, the average delay between the Pap smear and the first histology is equal to two months. It is longer than 6 months in seven cases. The diagnosis of cancer or high-grade lesion is confirmed histologically on a first biopsy of the cervix in 196 cases, a second or a third biopsy in 10 cases, an endocervical curettage in six cases and a surgical specimen in 32 cases. In the group 2, the histological diagnosis is normal-benign in 14 cases (presumed cytological false positives) and condyloma-CIN 1 in 23 cases (presumed overevaluations). DISCUSSION AND CONCLUSION: Results highlight benefits of interactive exchanges between clinicians and pathologists, and the necessity of review of discordant cases by several pathologists in due time, with written comments and coding of the conclusions of the review. Histological follow-up is late or not done in some women.

[Previous caesarean section is an operative risk factor in vaginal hysterectomy].

OBJECTIVE: We describe the intra and postoperative frequency of complications in vaginal hysterectomies for benign disorders in patients with a history of caesarean section. PATIENTS AND METHODS: Since 1996, 963 hysterectomies have been performed in our institution. 76.94% were performed exclusively by vaginal route (n = 741), 10.1% (n = 98) were by laparoscopic-assisted vaginal route and 12.9%, by pure abdominal route. We compared two groups of patients who underwent vaginal hysterectomy, with or without history of caesarean section. In each group we recorded the characteristics of the population and compared the intra and postoperative data, such as bladder or digestive tract wounds and haemorrhages. We used analysis of variance tests to compare means, chi2-tests and Fisher's exact tests for comparisons of numbers. A probability of P < 0.05 was adopted as the limit of significance. RESULTS: The frequency of haemorrhages was significantly higher in the patients with a history of caesareans. Bladder and intestine injury rates are significantly higher in the previous caesarean section group, but not significant for the bowel injuries. We compared the cumulative frequency of complications between the two groups. In the group with previous caesarean section, we recorded 18.3% of intra operative complications. In the group without history of caesarean section, we recorded 3.58% of complications. There is a significant difference between the cumulative frequency of complications in the two populations of patients in favour of the sub group without a history of caesarean scar (P < 0.0001). DISCUSSION AND CONCLUSION: A history of single or multiple previous caesarean section increases the intra operative risk in vaginal hysterectomies. The surgeon must take into account the history of caesarean section and be attentive to the previous operating time of the bladder and uterine region especially at the time of opening the anterior peritoneal cul-de-sac. Nevertheless, uterine scarring as a sequel to caesareans must not be a contraindication to the vaginal route.

[Management of type III female genital mutilation].

Female genital mutilation (FGM) consists in a non-therapeutic removal of part or all of the external genitalia and /or injury to the external genitalia. This practice in common in a few African countries and in Middle East. Mass immigration of African women to Europe in the past decade has brought the problems of FGM to these countries. There are four types of FGM. Many early (hemorrhage, infectious) and/or late (uro-gynecologic and obstetric) complications can be associated. The dermoid clitoridia cyst is the most frequently complication. Rigorous obstetrical labor monitoring is not possible. Therefore labor is longer and there are many delivery complications. The treatment is based on Gabbar's deinfibulation surgery which can be proposed when there are uro-gynecologic complications, or during pregnancy and labor. This method can lead to spontaneous vaginal delivery without perineal trauma. The aim of this article was to share our experience and inform obstetrician-gynecologists about FGM.

[Fluorescence imaging technique: diagnostic and therapeutic interest in gynecology].

Fluorescence techniques are presently used by several medical and surgical disciplines (dermatology, pneumology, urology, gastrointestinal surgery) for the diagnosis of pre-cancerous and cancerous lesions. The technique is based on the application of 5-aminolevulinic acid (5-ALA) which induces the production of an endogen photosensitizer: protoporphyrin IX (PpIX). Fluorescence detection of the infraclinical dysplasia lesion is based on the contrast between fluorescent pathological tissue and non-fluorescent healthy tissue. Moreover, there is a correlation between the degree of tissue dysplasia and fluorescence intensity. Fluorescence imaging could allow easier detection of infraclinical lesions enabling more well-targeted treatment. In gynecology, many experimental and clinical studies have been conducted on the detection and treatment of cervical dysplasia and the diagnosis and treatment of vaginal and vulvar diseases as well as the diagnosis of peritoneal micrometastasis from ovarian cancer, the diagnosis and treatment of endometrial alterations, and the treatment of locoregional recurrent skin breast cancer. The aim of this work is to present the fundamental principles of fluorescence imaging technical and to expose the diagnostic and therapeutic prospects in gynecology.

Value of human papillomavirus testing after conization by loop electrosurgical excision for high-grade squamous intraepithelial lesions.

OBJECTIVE: The aim of the study was to evaluate human papillomavirus (HPV) testing during the follow-up of patients after conization by loop electrosurgical excision for high-grade squamous intraepithelial lesion. METHODS: A prospective study was conducted on 205 patients who underwent conization for high-grade squamous intraepithelial lesion (CIN 2 or 3). Loop electrosurgical excision procedure (LEEP) was used in all cases. High-risk HPV testing was realized by the Hybrid Capture II system before and 3 months after conization. RESULTS: Of the 205 patients, 193 (94.1%) were positive for the HPV test before conization. Seventy-one were HPV positive after conization (34.6%). The margins were positive in 36.1%. Residual disease was observed in 27 cases (13.2%). Four patients (2%) developed a recurrence after a mean follow-up of 18.1 months (+/-12). There was no correlation between pretreatment HPV testing and the residual disease or recurrence. Patients with positive margins were significantly more likely to have residual disease than those with negative margins (P < 0.0001). Residual disease was more likely to occur when the posttreatment HPV test was positive (P < 10(-7)). All recurrences were observed in patients with a positive posttreatment HPV test (P < 0.05). Residual disease and recurrence were correctly predicted with a sensitivity of 81 and 100%, respectively, and a negative predictive value of 96 and 100%. CONCLUSION: Posttreatment HPV testing could be useful in the follow-up of patients after conization. In case of negative posttreatment HPV testing, the frequency of follow-up could be reduced, particularly in those patients with free margins.

Successful treatment of extremely severe fetal anemia due to Kell alloimmunization.

BACKGROUND: Repeated plasmapheresis was used to prevent fetal death from severe anti-Kell alloimmunization until intrauterine transfusions were feasible. CASE: Repeated maternal plasma exchanges (N = 40) beginning at 7 weeks' gestation were used to treat severe anti-Kell alloimmunization. Ultrasound examination at 19 weeks' gestation revealed diffuse hydrops in this fetus (umbilical venous hemoglobin, 1.2 g/dL), which then required nine intrauterine transfusions through 34 weeks. A healthy 3840-g girl was delivered by cesarean delivery at 36 weeks. Despite aplastic anemia during the first 3 months of life, she is healthy and has no observable abnormalities at age 8. CONCLUSION: A highly aggressive course of plasmapheresis and intrauterine transfusions can successfully treat fetal anemia caused by anti-Kell alloimmunization even when fetal hemoglobin is extremely low.

Management of female genital mutilation in Djibouti: the Peltier General hospital experience.

Female genital mutilation (FGM) is still performed on 98% of Djiboutian women. Infibulation (FGM type 3) is the most widely used method of FGM in Djibouti. Even though this operation is mutilating, illegal and sometimes results in death, it is still practiced at approximately the same rate as in the past. Mass immigration of African women to Europe, Canada, Australia and the United States in the past decade has brought the problems of FGM to these countries. Female genital mutilation is a problem unfamiliar to most Western obstetrician-gynecologists. A tight infibulation can be a high risk for the mother and fetus if not handled by a skilled operator. It can lead to an unnecessary cesarean section as a result of the fear of handling infibulated women. Therefore, Western physicians need to be informed. The aim of this article was to share our experience of FGM. It will focus on FGM in Djibouti, its types, epidemiology and health consequences. It will present the management of obstetric and gynecologic complications and discuss medico-legal and health service measures to combat these dangerous and unnecessary practices

The vaginal patch plastron for vaginal cure of cystocele. Preliminary results for 47 patients.

OBJECTIVE: We describe a new surgical technique (the vaginal plastron) for the treatment of cystocele by the vaginal route. The technique is based on bladder support by a vaginal strip (6-8cm in length and 4cm in width), isolated from the anterior colpocele, left attached to the bladder, associated with a suspension of this strip by its fixation to the tendinous arch of the pelvic fascia by six lateral sutures (three on each side of the plastron). The vaginal plastron is then covered by tucking it under the anterior colporraphy. STUDY DESIGN: We evaluated the short-term functional and anatomical results of the first 47 patients to have undergone this treatment between October 1997 and June 1998. The average age of the patients was 69 years. Cystoceles were associated with urinary stress incontinence in 38.3% of cases, with hysterocele or prolapse of the vaginal dome in 87.2% of cases, with an elytrocele in 19.1% of cases and a rectocele in 70.2% of cases. Of the 45 patients having had a hysterectomy combined with the vaginal plastron or in their past history, 44 (99.77%) had a Richter sacro-spino-fixation and 17 (38%) had a Campbell procedure combined with the vaginal plastron. All patients underwent a posterior perineorraphy with myorraphy of the elevators. RESULTS: Average follow-up was 16.4 months with extremes of 6-26 months and concerned 46 patients (one patient was unavailable). Ninety-three percent of the cystoceles were considered treated. One case of imperfect anatomical outcome was noted (persistence of stage 1 cystocele in one patient) together with two other cases of failure of the treatment of cystocele (relapse to stage 2 cystocele). CONCLUSION: Proposed as a curative treatment of cystocele and combined with the Richter fixation, the plastron provides a surgical solution to the problem of cystocele relapse arising after vaginal treatment of prolapse by sacro-spino-fixation alone (10-20% according to Richter). Short-term results are encouraging, however, medium- to long-term results (36-60 months) are necessary in order confirm the usefulness of this surgical technique.

[Cure of cystocele with vaginal patch].

OBJECTIVE: To describe an original technique for transvaginal cystocele repair and to report the anatomical and functional results of the first 47 patients operated by this technique. The operation combines suspension, by six sutures to the tendinous arches of the pelvic fascia, of a vaginal patch measuring 6 to 8 cm long by about 4 cm wide left in contact with the cystocele. The vaginal patch is then buried under the anterior colporraphy suture. Spinal fixation, hysterectomy, levator myorrhaphy or urinary incontinence repair are also performed as necessary. METHODS: Descriptive retrospective study of 47 patients undergoing transvaginal repair of prolapse between October 1997 and June 1998. All patients presented external prolapse with grade III cystocele, associated with urinary incontinence in 38.3% of cases and hysterocele or vaginal prolapse in 87% of cases. The mean age of the patients was 69 years. The uterus was preserved in two cases, but hysterectomy was performed in the other 45 patients, together with Richter spinal fixation in 44 cases An associated levator myorrhaphy was performed in every case. RESULTS: The mean follow-up was 16.4 months (range: 6 to 26 months) in 46 patients. The cystocele was considered to be cured in 93% of patients, one patient had an asymptomatic grade I cystocele and surgery was unsuccessful in two patients who developed recurrent grade II cystocele. CONCLUSION: The technique presented here is a curative treatment for grade III cystocele in menopaused women associated with Richter spinal fixation, and prevents the risk of cystocele described after transvaginal treatment of prolapse by spinal fixation alone (10 to 20%). The short-term results are encouraging, but they need to be confirmed by a follow-up of at least 5 years.

[Tumor markers and ovarian cysts].

A practical review of tumor markers, particularly CA125 is proposed. The questions are: what is the role of CA125 assay in cancer screening programs, can preoperative CA125 level predict the benign or malignant nature of an adnexal anomaly, can postoperative CA125 predict the quality of surgical resection of cancer of the ovary?

Neuroendocrine tumors of the uterine cervix. Clinicopathologic study of five patients.

Four main clinicopathologic features of neuroendocrine tumors (NETs) of the cervix may be stressed: primary diagnosis at an advanced stage, early nodal metastasis even for low disease, early failure of appropriate local treatment (surgery and/or radiation therapy) and aggressive clinical treatment. Five patients with NET of the uterine cervix (small cell carcinoma type) are reported (one stage I, two stages II, one stage III and one stage IV). One patient was treated by surgery combined with radiation therapy, one by surgery combined with chemotherapy and one by surgery with radiation therapy and chemotherapy. Two patients received radiation therapy alone. Three early stage patients are alive with no evidence of disease 8, 26 and 41 months after diagnosis. The two patients with advanced stage died of disease, 3 and 12 months respectively, after diagnosis. Combination chemotherapy (cisplatin and etoposide) is warranted in disseminated NETs. Neoadjuvant or adjuvant chemotherapy should be combined with radiation therapy and surgery even in early stages.

[Gene therapy and ovarian cancer: update of clinical trials].

Ovarian cancer is the first leading cause of death from gynecologic cancer. Advances in therapy are needed to obtain complete response after surgery and/or chemotherapy. Gene therapy is a new alternative therapeutic approach. 380 gene therapy clinical trials (3173 patients) are going to be assessed. 63% of these trials concern therapy of cancer. 16 gene therapy clinical trails are applied to ovarian cancer. These 16 clinical trials assess different treatment strategies: Mutation compensation by replacement of an altered tumor suppressor gene (p53, BRCA1); Molecular chemotherapy by transfer of a suicide gene (HSV-tk gene); Antitumoral immunotherapy by cytokine gene transfer (IL2, IL12); Oncogene inhibition (erb-B2 gene); Multi Drug Resistance gene transfer. A knowledge of basis concepts of gene transfer strategies, is needed to understand these different treatment strategies. Thus, the goals of this review are, first, to provide the basis concepts of gene transfer strategies to the obstetrician-gynecologist and second, to submit recent gene therapy clinical trials about ovarian cancer.

Villoglandular papillary adenocarcinoma of the uterine cervix.

Villoglandular papillary adenocarcinoma of the uterine cervix was recently (1989) described by three main histological features: exophytic proliferation, papillary architecture and mild to moderate cellular atypicality. The authors report a case of villoglandular papillary adenocarcinoma, clinical stage IB, which was peculiar because of its association with a co-existing and simultaneously discovered invasive squamous cell carcinoma. These two patterns were juxtaposed and not intermingled. The patient was treated with radical hysterectomy followed by vaginal radiation therapy. She remains without evidence of recurrence after 12 months of follow-up. Five main clinicopathological features of the villoglandular papillary adenocarcinoma could be stressed: rare histological variant (72 described cases), young age of patients (25-45 years old), superficial stromal invasion, usual association with other tumoral patterns (in situ or invasive adenocarcinoma as well as in situ or invasive squamous cell carcinoma) and excellent prognosis. For selected cases, a conservative surgical approach (cervical conization) was possible.

[Mechanical resistance of pelvic ligaments used for incontinence or prolapse surgery].

OBJECTIVE: Underline the objective strength of the pelvic ligaments. PATIENTS AND METHODS: Twenty nine human female pelvis cadavers, whose storage conditions differed, were used in our study. In each cadaver we dissected all the ligaments used in pelvic surgery. A subjective clinical evaluation of the ligament properties was performed by visual observation as well as by finger palpation. Ligaments were classified into three groups in terms of thickness and apparent strength following finger palpation, high, doubtful and low apparent quality ligaments. Then a suture taking the entire ligament switched the ligaments and a force was applied on the vagina axis until tearing. The device used for strength measurement during traction was a Samson type force gauge, which was developed for the purpose of our study. Results were given in Newtons. RESULTS: We found a great variability in the values obtained at tearing with maximal values at 200 newtons and minimal at 22. Individually measured, ligament strength varied between individuals, and for a same patient between the type of ligaments and the side. The pre-vertebral ligament was on average the strongest. For bilateral ligaments, there was no difference between the left and right side. The iliopectineal ligament was statistically significantly stronger than sacrospinous and arcus tendineus of pelvic fascia. There was a correlation between subjective evaluation and objective strength measurements. DISCUSSION AND CONCLUSION: We performed the only study of the strength of pelvic ligaments at tearing. These are, however, routinely used in the cure of prolapse and urinary incontinence. Our results show that there is a great variability in strength between individuals, and for a same patient between the types of ligaments and side. These observations could explain some of the surgical intervention failures and demonstrate the importance of per-operative strength evaluation. Per-operative subjective evaluation on strength is related to objective measurements and could be used to determine the type of ligaments to be used for surgical assembly suspension.
