Randomized trial: treatment of genitourinary syndrome of menopause using radiofrequency.

OBJECTIVE: A randomized controlled study was conducted to evaluate the safety and efficacy of radiofrequency treatment in postmenopausal women not willing to use or presenting a contraindication for menopause hormone therapy (MHT) and suffering from genitourinary syndrome of menopause (GSM). METHODS: A prospective randomized open study evaluated the effect of radiofrequency treatment versus a gel (control group) in postmenopausal women suffering from GSM. Patients were assessed at baseline and after 10-12 weeks of treatment for severity of vulvovaginal atrophy, dyspareunia, pH, vaginal smear maturation index, Vaginal Health Index and Female Sexual Function Index. The difference at baseline and after 10-12 weeks of treatment and the difference in improvement were tested between groups by a two-sample t-test and the Mann-Whitney test. RESULTS: Due to the COVID-19 pandemic, we were only able to treat 48 patients (24 patients using radiofrequency and 24 patients using a gel). Globally, at the end of the study, there were no differences in changes of the measured outcomes between the group of women treated with radiofrequency and the control group. CONCLUSION: Radiofrequency treatment was found to be safe, but was not superior to a gel, although the study lacked power. The study was registered at ClinicalTrials.gov (NCT03857893).

[Rare complication of a late abortion: a case report]. / Complication rare d'une interruption volontaire de grossesse tardive.

We report the case of a young woman who presented with acute abdomen at our hospital. The control revealed the presence of fetal parts in extra-uterin and intra-abdominal place after a late abortion. The patient was succesfully operated by celioscopy.

Primary ovarian carcinoid tumor with luteinized stromal cells.

BACKGROUND: Primary ovarian carcinoid tumors are rare. Distinct histologic patterns have been described in the literature as insular, trabecular, mucinous and mixed types. CASE REPORT: We describe a case of 71-year-old woman diagnosed with a left ovarian tumor. Frozen section examination identified the mass as a sex-cord stromal tumor. The surgically resected tumor was diagnosed as an insular carcinoid tumor with unusual luteinized stromal cells. Histologic diagnosis complied with results acquired by immunohistochemical with positivity of tumor cells for neuroendocrine markers and positivity of luteinized stromal cells for alpha-inhibin, calretinin and Melan A. CONCLUSION: Ovarian carcinoid tumor can be extremely heterogeneous. The purpose of our report was to show that the ovarian carcinoid tumor can be associated with stromal luteinization, mimicking a sex-cord stromal tumor.

Assessment of proliferating activity in Paget's disease of the nipple by double stain immunohistochemistry.

Paget disease of the nipple is a rare disease characterized by the presence of malignant glandular cells within the squamous epithelium of the nipple. The most common hypothesis to explain the development of Paget's disease is an intraepithelial epidermotropic migration of malignant epithelial cells originating from an underlying intraductal carcinoma. Although the immunohistochemical properties of Paget cells in the nipple have been extensively studied, their proliferating characteristics remain paradoxically poorly studied. In the present study we have investigated the proliferating activity of Paget cells in the nipple by using double stain immunohistochemistry with both Ki-67 (a protein which is expressed in all active parts of the cell cycle) and cytokeratin 7 (a highly sensitive marker of Paget cells). Ten cases of Paget's disease and the associated intraductal carcinomas (n = 10) and/or invasive carcinomas (n = 4) were tested. The mean Ki-67 index was in Paget's disease (26% +/- 10), in intraductal carcinomas (23% +/- 8) and/or in invasive carcinomas (20% +/- 8) (p > 0.05). This is the first report to convincingly demonstrate by specific double stain immunohistochemistry that Paget's disease and underlying intraductal carcinomas share a close proliferating activity.

Glucocorticoid receptor expression in cervical intraepithelial neoplasia and invasive squamous cell carcinoma of the cervix.

OBJECTIVES: Glucocorticoids (GCs) are used in cancer treatment to cause programmed cell death in transformed cells of the hematopoietic system and to lessen side-effects as nausea, vomiting, edema formation and allergies to specific chemotherapeutic agents. GCs act also as cofactor with human papillomaviruses in the etiology of cervical cancer. Moreover, recently GCs were described as inhibitors of some chemotherapy or radiation-induced apoptosis. The presence or not of a glucocorticoid receptor (GR) in normal and abnormal exocervices is thus interesting. METHODS: To clarify the issue, we tested by immunohistochemistry the expression status of GR in normal cervix epithelium (n = 30), in low-grade cervical intraepithelial neoplasia (LSIL) (n = 30), in high-grade cervical intraepithelial neoplasia (HSIL) (n = 30) and in invasive squamous cell carcinoma (ISCC) (n = 30). All the patients with these lesions have a corresponding liquid-based cytology and were proved to be HPV-positive by using hybrid capture 2 methodology with probes against high-risk oncogenic HPVs. The evaluation of GR expression was performed by using the H-score system and an H-score > 50 was considered positive. RESULT: GR expression was observed in normal epithelium, LSIL, HSIL and ISCC. No statistically significant difference concerning this expression was observed. CONCLUSION: Because GCs could play a positive role in the progression of cancer, our demonstration of GR persistence in cervix cancer cells raises concern about the widespread combined use of GCs with antineoplastic drugs or agents in the clinical management of cervix cancer in women.

Pl6 expression in Paget's disease of the breast.

BACKGROUND: Paget's disease of the nipple is generally associated with an underlying invasive cancer or an underlying ductal carcinoma in situ. Epidermotropic theory maintains that Paget's cells are derived from an underlying mammary in situ adenocarcinoma. Because p16 protein plays a major role in cell-cycle control and in tumoral cell mobility, we analyzed p16 expression in Paget's disease of the nipple and in associated underlying ductal carcinoma in situ. METHODS: The expression of p16 protein was analyzed by immunohistochemistry in eight cases of Paget's disease of the nipple with associated underlying ductal carcinoma in situ. The Student's t-test (2-tailed) was used to establish the equality of means. RESULTS: The expression of p16 protein was observed in 87.5% (7/8 cases) both in the nipple disease and in the associated underlying ductal carcinoma in situ. The difference between the two populations was not statistically significant. In normal breast tissue, no expression of the protein was observed. CONCLUSION: The positive p16 expression in Paget's disease of the nipple and the underlined ductal carcinoma in situ and its role in cell motility lead us to propose a role of p16 in the spread of this disease.

Does preoperative magnetic resonance imaging modify breast cancer surgery?

AIMS: To determine the impact of preoperative use of breast magnetic resonance imaging (MRI) in therapeutic surgical approach in women with breast cancer. MATERIALS AND METHODS: Preoperative contrast-enhanced MRI of the breast was performed in 105 patients with suspected breast carcinomas. MRI findings were correlated with mammography (MMG) and ultrasonography (US). RESULTS: Histopathologic analysis revealed 144 breast carcinomas. The results of the MRI lead to a change in 17.1% of the planned surgical procedure. MRI imaging alone revealed 16 multifocal or multicentric tumors and four contralateral carcinomas. CONCLUSION: Breast MRI could be recommended as a pre-surgical diagnostic procedure in patients allocated to breast conservation surgery. Nevertheless, further studies are needed to determine if preoperative breast MRI leads to a decrease in tumor recurrence and in overall survival.

Pyocolpos in an elderly woman.

BACKGROUND: Pyocolpos, an uncommon accumulation of pus in the vagina, has not been previously reported in an elderly woman. CASE: A 76-year-old woman was hospitalised with post-menopausal bleeding and fever. Pelvic examination revealed an obstructed vagina. A gadolinium MRI showed pyocolpos. After surgical drainage, the patient rapidly recovered. CONCLUSION: Pyocolpos in elderly woman may appear spontaneously without any history of gynaecologic cancer or trauma.

[Anti-HPV vaccination against cervical cancer]. / La vaccination anti-HPV contre le cancer du col utérin.

The aim of this review is to present a new light about the HPV infections, their spontaneous evolutions, and their consequences on the transformation of the target tissues. It enlightens the need for vaccination both as a preventive tool and therapeutic agent and the progresses reached so far. HPV infection is often transient and spontaneously reversible. HR HPV persistence is the major cause of cancerous transformation of several tissues. Preventive vaccination has already demonstrated a remarkable efficiency against the development of risk HPV ano-genital infections. Therapeutic vaccination is now also developed to cure the pre existing lesions. Some new screening protocol can be derived from these experiments. Both preventive and therapeutic HPV vaccinations will probably change within the next few years our approach for the screening and therapy of HPV related diseases. Mass vaccination of adolescent female should lower the frequency of these very frequently lethal affections.

Bilateral extensive vascular calcification of the breast associated with coagulative necrosis: a calciphylaxis-like syndrome.

A case of asynchronous bilateral breast necrosis in a 40-year-old woman with untreated chronic hypercholesteraemia is described. Mastectomies were performed, and histological examination revealed bilateral breast calciphylaxis characterized by extensive vascular calcification with coagulative necrosis. Breast calciphylaxis is a rare disease clinically characterized by progressive tissular necrosis with secondary cutaneous ulceration and by vascular calcification and thrombosis. However, the nature of the vascular calcification has remained poorly understood up to now, owing to the absence of any precise mineralogical examination. In this case the mineral deposits were analysed for the first time: only hydroxyapatite was found. The etiology is discussed, and the high cholesterol rate of the patient is implicated.

Adenoid cystic carcinoma of Bartholin's gland: what is the optimal approach?

AIMS AND METHODS: We report the case of a locally advanced adenoid cystic carcinoma of Bartholin's gland which required posterior pelvic exenteration, radical vulvectomy and ablation of the ischiorectal fossa in order to obtain tumour clearance with negative margins. Including this case, only three pelvectomies have been performed for this disease. This is the first reported case in which a controlateral unsuspected intravulvar metastasis was found on histology. RESULTS AND CONCLUSIONS: No consensus exists on the adequate surgical management of this particular disease. Nevertheless, a review of the literature and this reported case suggest that radical vulvectomy with negative margins should be preferred to wide local excision as the primary surgical procedure. It also suggests that inguinofemoral lymph-node dissection should only be performed when suspect lymph nodes are found at clinical examination.

Cervical response to vaccination against HPV16 E7 in case of severe dysplasia.

OBJECTIVE: To evaluate the tolerance to vaccination against human papillomavirus (HPV)16 E7 (in SB adjuvant ASO2B) and its histological and immunohistological effects on HPV16 associated high-grade cervical dysplasias associated with HPV16. STUDY DESIGN: Five patients with histologically demonstrated severe cervical dysplasia (CIN3) HPV16 positive were injected three times before conization was performed 2 months after the first injection. We studied cytological, histological, proliferative pattern and immune profile before and after vaccination. The slides were compared with those obtained from non-injected patients. RESULTS: The injections were well tolerated and the specimens displayed a limited regression of the lesions. Nevertheless, massive CD4 and CD8 T cell lymphocytic infiltration was noticed after vaccination. DISCUSSION: We conclude that the vaccination we used provides an obvious immune histological reaction in the HPV infected cervix and that the 2 months delay before the final step (conization) is done is probably too short.

A first case of Streptococcus bovis bacteremia and peritonitis from endometrial cancer origin.

BACKGROUND: The most important clinical infections caused by Streptococcus Bovis are bacteremia and endocarditis. Usually, Streptococcus Bovis bacteremia has been described in association with bowel pathology. CASE REPORT: A 67-year-old woman with an history of endometrial cancer Ic was admitted with the suspicion of peritonitis at examination. At exploratory laparotomy, a total hysterectomy was performed and the abdomen was drained. Histology revealed an uterine adenocarcinoma staged IIIa with intramyometrial cocci accumulation. Streptococcus Bovis was isolated from the peritoneal fluid cultures and three haemocultures. CONCLUSION: Because we excluded bowel pathology and endocarditis, this is the first case of Streptococcus Bovis bacteremia from endometrial cancer origin.

[Which contraception in 2004?]. / Quelle contraception en 2004?

The part of the hormonal contraception in Belgium is important. The mode of administration has diversified during these last years. Indeed, in order to prevent spotting and breakthrough bleeding sometimes associated with low dosage pill, trans mucosa as well as trans cutaneous hormone administrations are interesting developments. The use of these "non oral" administrations also aim at reducing the risk of forgetting the contraceptive pill which is, together with the leave of the method for intolerance the major cause of unplanned pregnancies in young women.

[Treatment of urinary incontinence in women and the role of physiotherapy]. / Le traitement de l'incontinence urinaire chez la femme et la place de la kinésithérapie.

Physiotherapy including pelvic floor muscle exercises, vaginal cones, biofeedback or electrical stimulation can be recommended as first step therapy for genuine stress incontinence. However physiotherapy has its limitations: 30% of women do not improve at all and only 10 to 20% of women are totally dry after treatment. In case of failure or insufficient response, surgery must be considered. Until recently, the gold standard for the treatment of urinary incontinence was the "Burch" procedure. However the surgical approach has been considerably modified since the introduction by Ulmsten in 1995 of the tension-free vaginal tape (TVT) and more recently of the "Uratape". Short and mid-term results of the TVT are very encouraging with about 85% "dry patients" at five years follow-up. This technique can also be used with good results in patients with a low urethral pressure (< 20 cm H2O). Of course the superiority of TVT over other "classical techniques" must be confirmed by randomized comparative studies.

[A new approach in techniques to treat urinary incontinence: TVT (tension free vaginal tape)]. / Une nouvelle approche dans les techniques de cure d'incontinence urinaire: le TVT (tension free vaginal tape).

The indications and the surgical technique of a newly developed operation for the correction of female urinary incontinence (the Tension free Vaginal Tape) are described. This technique is based on a new etiological concept of urinary incontinence and ensures the patient a reduced morbidity (local or regional anaesthesia) and hospital stay (theoretically adapted for a one day clinic). Mid-term results (84% success rate after a median follow up of 3 years) are promising but must be confirmed at the long term. We relate our experience of 30 cases with a success rate of 93% but entached with a high rate of postoperatory urinary urgency. This leads us to emphasise a strict adherence to the indications and an absolute respect of the technique as originally described.

[The gynecology-obstetrics department]. / Le Service de Gynécologie-Obstétrique.

The scientific and clinical activities of the Department of Obstetrics and Gynaecology have involved the three main subdivisions: the gynecological surgery, the obstetrics and fetal medicine, the endocrinology and the reproductive medicine. Minimal invasive surgery including laser assisted laparoscopy or robotic assisted surgery has been particularly developed. Endometriosis, a frequent and sometimes particularly invasive disease, and oncologic surgeries have been developed in collaboration with the digestive surgery department. The department has also contributed to the comprehension and treatment of prenatal pathologies such as premature labor and deliveries or the gestational diabetes. The department has supported the development of techniques to study the fetal well-being in utero: the prenatal echography, the chorionic villous sampling, the amniotic puncture or the cordocentesis for prenatal genetic diagnosis or fetal infectious contaminations, the CMV transmission more specifically. In endocrinology and reproductive medicine, the department has mainly developed the in vitro fertilization techniques. The prolonged embryo culture, the study of preimplantation embryo metabolism, the preimplantation genetic diagnosis and the cryopreservation of ovarian fragments to preserve fertility in women undergoing oncologic treatments represent the more recent developed topics. Finally, the security of viral transmission in assisted procreation and the treatment of these patients with chronic viral diseases (Hepatitis C or HIV) are another domain with important scientific activity.

Laminin-5 gamma 2 chain expression in cervical intraepithelial neoplasia and invasive cervical carcinoma.

BACKGROUND: To analyze the expression of laminin-5 gamma 2 chain, a protein which plays a major role in keratinocyte migration, in cervical intraepithelial neoplasia (CIN), and invasive cervical carcinoma associated with high-risk oncogenic human papillomaviruses (HR-HPVs). MATERIAL AND METHODS: The expression of laminin-5 gamma 2 chain protein has been analyzed by immunohistochemistry in 17 cases of low-grade squamous intraepithelial lesions (LSIL-CIN1), 35 high-grade squamous intraepithelial lesions (HSIL-CIN2/3), 18 microinvasive or invasive carcinomas, and three metastatic lymph nodes. All these lesions have been proved to contain HR-HPVs and were also positive for p16 protein which classically is overexpressed at all stages of cervical neoplasia and dysplasia linked with HR-HPVs. 20 cases of normal cervix served as controls. RESULTS: The expression of laminin-5 gamma 2 chain protein was observed in 100% of invasive or microinvasive carcinoma and in their related lymph node metastasis with an immunoreactivity located preferentially at the invasive front of the lesions. All the HSILs (100%) associated with invasive carcinoma were also positive. In contrast, in HSILs without associated invasive component, the expression of the protein has been found in only 34% of cases. In positive HSILs, laminin-5 gamma 2 protein was expressed in basal layers. In LSILs and normal epithelium, no expression of the protein was noted. CONCLUSIONS: We conclude the following: (i) the expression of laminin-5 gamma 2 is a late event in cervical carcinogenesis increasing with the grade of dysplastic lesions; (ii) laminin-5 gamma 2 expression facilitates the identification of invasive and microinvasive lesions which could be difficult to diagnose on the basis of routine stains; (iii) laminin-5 gamma 2 expression in HSILs could potentially identify those lesions with a more increased risk of tumor progression.

Impact of surgical resection of rectovaginal pouch of douglas endometriotic nodules on pelvic pain and some elements of patients' sex life.

STUDY OBJECTIVE: To assess the impact of laparoscopic resection of endometriotic nodules in the rectovaginal pouch of Douglas on women's pain symptoms, analgesic intake, work absenteeism, work difficulties, and some elements of sex life. DESIGN: Observational study (Canadian Task Force classification II-2). SETTING: Gynecology department at a university hospital. PATIENTS: Twenty-six women with rectovaginal pouch of Douglas endometriotic nodules and no evidence of other potential cause of pain at physical examination, laparoscopy, and transvaginal ultrasonography. INTERVENTION: Laparoscopic resection of endometriotic nodules with the CO2 laser until no residual induration was felt in surrounding tissues. MEASUREMENTS AND MAIN RESULTS: Significant statistical differences were found between preoperative and postoperative pain scores, percentages of women absent from work, percentages taking analgesics or nonsteroidal antiinflammatory drugs, and percentages having work difficulties due to pain. A significant difference also was found in frequencies of sexual desire and coitus. CONCLUSION: Endometriotic nodules in the rectovaginal pouch of Douglas may be responsible for major pelvic pain and also for sexual dysfunction (lack of sexual desire, dyspareunia). Laparoscopic resection of the nodules significantly improves these conditions. (J Am Assoc Gynecol Laparosc 8(1):55-60, 2001)

Ki-67 immunostaining activity is higher in positive axillary lymph nodes than in the primary breast tumor.

BACKGROUND: The monoclonal antibody Ki-67 allows to investigate the proliferative activity of tumor and is a clinically useful marker to characterize breast cancer. In this study, we have compared Ki-67 activity in 38 primary breast tumors and in their respective positive axillary lymph nodes (ALNs). METHODS: Immunohistochemistry with the monoclonal antibody against Ki-67 was performed in 38 nodes positive breast carcinomas and in their respective positive ALNs. Statistical analysis was performed with the Student's t-test (2-tailed) for equality of means. RESULTS: The proliferation index measured by Ki-67 expression was significatively higher (p < 0.02) in ALN than in the primary tumor (29.8% v.s. 21.8%). CONCLUSION: These results strongly suggest a higher proliferation and perhaps aggressivity of metastatic neoplastic cells when compared with their respective primary tumor. Perhaps, in the future, these differences in proliferation behavior might be taken into account when considering the choice of the adjuvant therapy.
