Prenatal diagnosis of fetal corpus callosum agenesis by ultrasonography and magnetic resonance imaging

Corpus callosum agenesis (CCA) was evaluated by ultrasound examination and magnetic resonance imaging (MRI) in 14 cases. Ultrasonography was able to suspect CCA by indirect signs but a definitive diagnosis of CCA was achieved in only four cases. MRI was able to diagnose complete CCA in 13 cases and showed absence of the posterior portion of the corpus callosum in one case. Additional neurological abnormalities including heterotopia, gyration anomaly, asymmetry of the cerebral hemispheres, and Dandy‐Walker variant were documented in five cases, as well as an ocular anomaly which was present in one case, by MRI examination. Prenatal counselling for fetal agenesis of the corpus callosum is difficult as the prognosis is uncertain. The association with other cerebral abnormalities increases the likelihood of a poor outcome and ultrasonographic assessment of the fetal brain is limited. We found MRI to be a safe and useful additional procedure to complement ultrasonographic diagnosis or suspicion of CCA.

Hysteroscopic metroplasty for septate uterus and repetitive abortions : reproductive outcome

OBJECTIVES The aim of this study is to assess fertility outcome and obstetrical prognosis of 63 patients after hysteroscopic section of uterine septa. MATERIALS AND METHODS This is a retrospective study about 63 patients consulting for septate uterus and repeated pregnancy loss or abnormal fetal presentation between January 1988 and December 1996 in La Conception hospital in Marseille. Septal lysis was performed with microscissors or resectoscope. Statistical analysis was performed using the CHI2-test. RESULTS The anatomical result was considered satisfactory in 57.1% of cases. Forty-five pregnancies were obtained, two after an IVF-program in 56 patients. Twenty-eight living children were born: twenty-six at term. Twenty patients delivered normally. Two women are still pregnant. Obstetrical prognosis of these patients is statistically improved by the treatment (P=0.001). CONCLUSION Obstetrical prognosis of patients presenting repeated pregnancy loss and septate uterus is statistically improved by hysteroscopic metroplasty.

Hysteroscopic resection of endometrial polyps: a study of 195 cases

OBJECTIVE To ascertain the therapeutic efficiency of hysteroscopic resection for the treatment of endometrial polyps in women with abnormal uterine bleeding and postmenopausal metrorrhagia. SETTING University hospital. DESIGN Retrospective consecutive patient follow-up. MATERIAL AND METHODS From 1987 to 1997, 195 patients with haemorrhagic endometrial polyps were treated with hysteroscopic resection in our department. RESULTS Five complications occurred, but no major complications were noted. A total of 89.2% of the patients remained in contact after hospitalization. After long term follow-up (5.2 years), successful results were obtained in 80% of the patients with polyp resection without associated endometrial ablation. Further surgery (hysterectomy) was required in only five women. CONCLUSION Transcervical resection is the gold standard for treatment of endometrial polyps.

Hysteroscopic management of uterine synechiae: A series of 102 observations

This retrospective study concerns 102 cases of intra-uterine adhesions treated by exclusive hysteroscopic approach. Fifty-two patients (51%) presented with reproductive problems, 44 patients (43%) with menstrual problems and 6 were asymptomatic. Seventy-eight patients (76.5%) had an antecedent endometrial trauma on a gravid uterus. One hundred and forty-eight operative hysteroscopies were performed to treat 102 patients; 70 patients were treated in one endoscopic session (68.6%), 23 in two sessions (22.6%), 4 in three sessions (3.9%) and 5 in four sessions (4.9%). We report no infectious, hemorragic or metabolic complication but 6 perforations (5.8%). The mean follow-up is 24.4 months (from 6 to 46 months). Ten patients did not keep contact during follow-up. A good anatomical result was obtained in 88 patients (86.2%) after one or two hysteroscopic sessions. A good result on menstrual problems was obtained in 75% of the cases, especially in amenorrhea (90.5% success rate). The reproductive outcome is more disappointing. We obtained 34 pregnancies in 28 patients (10 abortions, 24 live born children). Twenty-two patients achieved no pregnancy (44%), but 13 of these patients presented with additional infertility factors.

Prenatal diagnosis of fetal cerebral abnormalities by ultrasonography and magnetic resonance imaging

We found magnetic resonance imaging (MRI) of the fetal brain to be effective in confirming or denying diagnosis of fetal cerebral defects when ultrasonography was inconclusive or incomplete. In this paper we describe 31 cases in which ultrasonographic evidence of fetal brain defects was verified by MRI. MRI was performed after curarization of the fetus. In 21 cases, ultrasonographic evidence was confirmed by histological study of the fetus or postnatal radiological examination. In 10 cases, ultrasonographic diagnosis was denied by MRI and healthy infants were born. In one case of cerebral toxoplasmosis, ultrasonography detected periventricular calcifications but MRI was normal. In 20 cases MRI ascertained or further documented the ultrasonographic findings. However in 4 of these 20 cases autopsy of the fetus was required to determine the exact nature of the lesion.

Relevance of HPV mRNA detection in a population of ASCUS plus women using the NucliSENS EasyQ® HPV assay

BACKGROUND DNA- and mRNA-based assays are the main tools used for detecting human papillomavirus (HPV) nucleic acid in clinical samples. A recent tool, NucliSENS EasyQ HPV, uses a new concept to directly detect the expression of HPV oncogenic factors (E6 and E7) from the most prevalent HPV genotypes in cervical cancer (16, 18, 31, 33 and 45). OBJECTIVES The primary aim of the study is to assess the accuracy of NucliSENS EasyQ HPV in detecting high-risk (HR) HPV in a population of atypical cells of undetermined significance/low-grade squamous intraepithelial lesion/high-grade squamous lesion (ASCUS/LSIL/HSIL) patients using a clinical cut-off of a cervical dysplasia (CIN2+) histology. The secondary aim is to compare this mRNA-based assay with the DNA-based hybrid capture II (HCII) assay. STUDY DESIGN The study population comprised 140 women referred for colposcopy and histology. NucliSENS EasyQ HPV test, hybrid capture II (HCII) test and linear array (LA) test were assessed on all samples. All the tests were performed on the samples collected in PreservCyt liquid media for liquid-based cytology (ThinPrep Pap test). RESULTS The clinical specificity of the NucliSENS EasyQ HPV was 63% for the detection of CIN2+ or HSIL patients, significantly higher than the specificity of HCII and LA (49% and 45%, respectively, p<0.05). Agreement between HCII and NucliSENS EasyQ HPV was fair (k=0.49) and was good between HCII and LA (k=0.88). HPV 16 was the most-detected type (49% with NucliSENS EasyQ HPV and 56% with LA), and HPV 31 was the second most-detected HPV type (31% with NucliSENS EasyQ HPV and 29% with LA). CONCLUSIONS The NucliSENS EasyQ HPV assay has interesting clinical sensitivity and specificity for the detection of HPV types in CIN2+ patients and shows comparable diagnostic values with the HCII DNA assay. This assay allows simultaneous detection of HPV mRNA and determination of the type of the main prevalent oncogenic virus.

Postoperative infection and surgical hysteroscopy

OBJECTIVE To evaluate the risk of infection after surgical hysteroscopy. DESIGN Prospective observational study. SETTING University hospital. PATIENT(S) One thousand nine hundred fifty-two patients requiring operative hysteroscopy during a 10-year period from January 1990 to January 2000. INTERVENTION(S) Two thousand one hundred sixteen operative hysteroscopies were performed: 782 fibroma resections, 422 polyp resections, 623 endometrectomies, 90 uterine septa sections, and 199 lyses of synechiae. MAIN OUTCOME MEASURE(S) Postoperative infectious complications. RESULT(S) Thirty (1.42%) infections occurred. There were 18 (0.85%) cases of endometritis and 12 urinary tract infections. No other severe infectious complications were reported. The risk for early-onset endometritis was higher after lysis of synechiae compared with endometrectomy, fibroma, or polyp resections. However, the risk for early-onset endometritis was similar for endometrectomy, septa, fibroma, or polyp resections. CONCLUSION(S) Infectious risk following surgical hysteroscopy is low. No major infectious complications occurred. Risk for early-onset endometritis was higher after lysis of synechiae compared with other procedures.

Laparoscopic management of malignant ovarian cysts: a 78-case national survey. Part 1: pre-operative and laparoscopic evaluation

This paper reports a retrospective multi-institutional French survey carried out in 1992 to determine the incidence of laparoscopic management of malignant ovarian cysts. Of 5307 ovarian lesions treated endoscopically, 78 were malignant (1.47%) including 60 borderline tumors and 18 ovarian cancers. In 33% of cases preoperative diagnosis indicated that the tumor was benign. Preoperative findings were suspicious in 59%. Laparoscopic treatment was puncture in 23% of cases, partial exeresis in 51% and total removal in 26%.

Risk of Uterine Perforation during Hysteroscopic Surgery

STUDY OBJECTIVE To evaluate the rate of uterine perforation during different operative hysteroscopy procedures. DESIGN Observational study (Canadian Task Force classification II-2). SETTING Department of Obstetrics and Gynecology, La Conception Hospital, Marseille, France. PATIENTS One thousand nine hundred fifty-two women. INTERVENTION Of 2116 operative hysteroscopies performed, there were 623 endometrectomies, 782 myoma resections, 422 polyp resections, 199 adhesiolyses, and 90 uterine septa sections. MEASUREMENTS AND MAIN RESULTS Risk of perforation was evaluated according to hysteroscopic procedure. Severity of complications were also noted. In case of perforation, a management protocol was applied to prevent metabolic disorders and pelvic infections. Thirty-four perforations (1.61%) were reported. In 33 cases (97%) it was realized during the procedure and no complications occurred during follow-up. One perforation with hemorrhage was misdiagnosed during the intervention and required laparotomy. Perforation risk was higher during hysteroscopic adhesiolysis than during other procedures [endometrial ablation RR 9.39 (3.46-25.52), p <0.0001; uterine septa section RR 6.78 (0.91-50.6), p = 0.026; polyp RR 8.52 (2.60-30.80), p <0.0001 or myoma resection RR 7 (2.83-17.62), p <0.0001]. Perforation risk was comparable during endometrial ablation, uterine septa section, and polyp or myoma resection (p = 0.93). CONCLUSION Perforation risk is higher during synechiolysis than in other indications for hysteroscopy. Severe complications are rare but may be avoided if precautions are taken.
