[Paradoxical interactions between pregnancy and breast cancer]. / Effets paradoxaux de la grossesse sur le cancer du sein.

Interactions between pregnancy and breast cancer are complex and paradoxical. Epidemiological data show that nulliparity and late full-term pregnancy increase breast cancer risk. By contrast, early full-term pregnancy and multiparity are thought to be the most effective means of decreasing lifetime breast cancer risk. Paradoxically, young women diagnosed with breast cancer during pregnancy have a higher risk of dying from their disease. Moreover, there is a transient increase in risk of breast cancer in the first three to four years after pregnancy. After breast cancer treatment, there is no evidence that pregnancy increases the risk of breast cancer recurrence. Thus, it is not contraindicated in women previously treated for breast cancer and free of recurrence. Various physio-pathological mechanisms are involved in the protective effect of pregnancy, like cellular differentiation of mammary cells, mammary gland involution, circulating anti-mucin antibody and excretion in the milk of breast carcinogens. In the past, unfavorable effects of pregnancy were mainly attributed to precancerous cell proliferation induced by pregnancy-associated hormonal changes. However, recent studies suggest that the remodeling of cellular microenvironment and extracellular matrix during pregnancy and involution may contribute to enhanced invasive and metastatic potential of breast carcinomas.

[Advantages of laparoscopic assisted vaginal hysterectomy in surgery of endometrial carcinoma]. / Avantages de la voie vaginale coelio-assistée dans la chirurgie des cancers de l'endomètre.

INTRODUCTION: In to respect the principles of oncological surgery and to reduce the operative morbidity, the authors of this study propose to find the proper place of the laparoscopic-assisted vaginal hysterectomy in the surgery of endometrial carcinomas. PATIENTS AND METHODS: Between the 1st of June 2002 and 31 of May 2005, we realize a retrospective and comparative study for 36 laparoscopic-assisted vaginal hysterectomy and 20 laparotomies concerning 56 patients. RESULTS: In primary stages (stages I and II of FIGO), laparoscopic assisted vaginal hysterectomy is as powerful as the laparotomy whereas in more advanced stages, laparotomy was more complete and effective (p=0,07). One conversion case was observed (2.8%) in a context of peritoneal carcinosis (stage IIIc). There was not statistically significant difference about the operatives complications (p = 0.51). On the other hand, the postoperative comfort was so far better in the laparoscopic-assisted vaginal hysterectomy group (p=0.0002). The average delay of followed without relapses was 22,3 months in the laparoscopic-assisted vaginal hysterectomy group versus 23 months in the laparotomy group (p=0.51). CONCLUSION: Considering these results, the authors retain that, in primary stages (I-II, FIGO), laparoscopic-assisted vaginal hysterectomy represents a real option in the surgery of endometrial carcinoma. On the other hand, the advanced stages should be reserved for laparotomy.

[Breast cancer in men: are there similarities with breast cancer in women?]. / Cancer du sein chez l'homme : existe-t-il une similitude avec le cancer du sein chez la femme?

Male breast cancer is an uncommon disease although its incidence has increased over the recent years. Like other orphan diseases, male breast cancer is understudied. This disease has a lot of similarities with female breast cancer. Some differences are yet noticeable. This article describes three cases of carcinoma of the breast in men with a review of the literature on risk factors and treatment. A database must be started with epidemiologic information to understand this disease and its correlation with breast cancer in women.

Peripartum bacteremias due to Leptotrichia amnionii and Sneathia sanguinegens, rare causes of fever during and after delivery.

We report three cases of delivery and postpartum bacteremia due to unusual anaerobic bacteria in healthy young women. Leptotrichia amnionii bacteremia occurred during delivery in two mothers and was associated with fetal distress during labor. Conversely, Sneathia sanguinegens bacteremia occurred postpartum, 2 days after delivery, without consequence for the neonate.

[Femoral neuropathy after transversal suspubic laparotomies. Etiopathological explanation on the basis of an anatomical study]. / Paralysie du nerf fémoral dans les suites des laparotomies transversales sus-pubiennes: étude anatomique et hypothèses étiopathogéniques.

OBJECTIVES: Based on a case of transient troncular femoral neuropathy after the surgical treatment of a genital prolapse in a 46-year-old woman, a study was designed to better understand the mechanism of this postoperative complication. METHODS: The consequences of different varieties of transversal laparotomies were investigated in human cadavers. RESULTS: On the basis of the data from the anatomical evaluation, the most probable etiopathogenic explanation for the complication we observed is the compression of the femoral nerve, inside the psoas muscle, by the retractor lower edge. CONCLUSION: In the reported case, the outcome was simple with full sensory and motor recovery in the lower limb. The different mechanisms potentially involved in this kind of postoperative femoral neuropathies are reviewed and discussed.

[Peripartum dilated cardiomyopathies: is there a correlation with sexually transmitted diseases?]. / Cardiomyopathies dilatées du péripartum: existe-t-il une corrélation avec les maladies sexuellement transmissibles?

A revue of litérature about peripartum cardiomyopathy; a disease of unknown pathogenesis. Some retrospective studies suggest a relation with sexually transmitted diseases. Other risk factors were observed. Diuretics and digoxin are used in the treatment. Cardiac transplantation is the final solution but the affection could appear again. A database must be started with epidemiologic information to understand this disorder and its correlation with sexually transmitted diseases.

[Multidisciplinary management of aortic dissection complicating pregnancy]. / Prise en charge multidisciplinaire d'une grossesse compliquée de dissection aortique.

BACKGROUND: Most cases of aortic dissection observed in women under 40 years of age occur as a complication of pregnancy in patients with other risk factors. Case report. We report a case of dissection of the ascending aorta in a young primigravida at 35 weeks gestation. The risk factor was aortic regurgitation. Multidisciplinary management enabled fetal extraction followed by repair of the aorta. Outcome was favorable for both mother and child. DISCUSSION: A review of the literature shows a variety of etiological factors leading to this disease. Emergency diagnosis and management is mandatory. Obstetricians should be aware that pregnancy can be a triggering factor in patients with a predisposition, e.g. connective tissue disease. A complete cardiovascular evaluation should be conducted before conception and a suitable surveillance planned for the entire pregnancy. The aim of this careful follow-up it to avoid surgery in an emergency setting that could compromise prognosis for both mother and child.

[Laparoscopic surgery and "massive" obesity]. / Coeliochirurgie et obésité "massive".

OBJECTIVE: Massive obesity is an important risk factor in gynecology surgery. The traumatic effect of traditional laparotomy on the parietal wall is responsible for important per and postoperative morbidity. We evaluated the feasibility and advantages of the laparoscopic approach in these patients, both in terms of surgical procedure and anesthesia. METHODS: To evaluate the technique, we reviewed four patients with massive obesity (BMI > or =40 kg/m(2)) who underwent laparoscopic surgery in our department. For each patient, we studied the cardiovascular risk factors, indications for operation, surgical technique, anesthesia conditions and follow-up. RESULTS: From the surgical point of view, certain technical difficulties were noted such as the problem of exposure and coagulation difficulties for the vascular pedicles enveloped in a layer of fatty tissue. No conversion to laparotomy was necessary. From the anesthesiology point of view, unlike what was previously feared, there was a reduction in the high operative risk due to obesity, especially due to postoperative benefits. Follow-up in these four patients was uneventful. CONCLUSION: Patients who suffer massive obesity are in a high risk category for surgery and anesthesia. This high risk group can benefit most from the advantages of laparoscopic surgery compared with open surgery.

[Buprenorphine and pregnancy. Analysis of 24 cases]. / Grossesse et buprénorphine. A propos de 24 cas.

BACKGROUND: Maintenance therapy of drug-addict mothers with medical and psychosocial support may reduce complications (prematurity, growth retardation, fetal distress and fetal death). Methadone has been widely used during pregnancy with beneficial effects. Buprenorphine (BUP) is used more and more and shows the same beneficial effects. PATIENTS AND METHOD: Twenty-four pregnant women received BUP and their infants were enrolled in the study. Thirteen retrospective (GI) and 11 prospective (GII) cases were studied. In the GII, the women were treated and followed up in an interdisciplinary manner. RESULTS: Complications in GII were less frequent than in GI: 9 vs 30% of prematurity, 9 vs 46% of fetal growth retardation and 0 vs 23% of acute fetal distress. However, the frequency of withdrawal syndrome was the same in both groups, 63 vs 69%, though improvements came more rapidly in GII. CONCLUSION: This study shows that the use of BUP during pregnancy, combined with medical and psychosocial support, may reduce addiction complications. This support has to be maintained after the birth.

[Subareolar injection of 99m-Tc sulfur colloid for sentinel nodes identification in multifocal invasive breast cancer]. / Injection sous-aréolaire de sulfocolloïdes technétiés pour l'identification des ganglions sentinelles dans les cancers du sein invasifs à foyers multiples.

The objective were to study the relevance of the subareolar injection for sentinel node [SN] detection in multiple foci breast cancer. Seventy-nine patients with infiltrative breast carcinoma (diagnosed pre-operatively by core biopsy) and a mean age of 55 (31-78) years were enrolled. All patients were free of previous homolateral surgery, chemotherapy, locoregional radiotherapy or prevalent axillary lymph node. Using four 0.1 ml injections of 1.8 MBq, the technetium-99m 100 nm filtered sulfur colloid was injected by subareolar way (group I) in 16 cases of radiologically cancer with multiple invasive foci and 31 cases of radiologically unifocal cancer, and by peritumoral way (group II) in 32 cases of radiologically unifocal cancer. Scintigrams were obtained 2 to 4 hours after the injections and radioactive nodes were detected peroperatively 18 hours after the injection by intraoperative detection probe. Individual removal of all radioactive nodes was followed by axillary dissection at levels I and II of Berg including Rotter area control. All sentinel nodes were submitted to standard histopathological analysis on serial sections at 500 mu intervals completed by immunohistochemistry for cytokeratin on negative SN. SN were detected by scintigrams in 85% and 88% of the cases of group I and group II respectively, but in 98% and 97% of the cases of respectively both groups by intraoperative probe. Group I was composed of 69% ductal, 22% lobular and 9% tubular carcinomas, and group II of 87% ductal, 10% lobular and 3% tubular carcinomas. Seven and 5 radiologically unifocal tumors were in fact with multiple invasive foci at histology in groups I and II respectively. The complete scintigraphic procedure permitted the detection of a mean number of 2.7 (1-7) SN in group I and 2.3 (1-4) in group II (NS). In group I, the SN were metastatic in 22 patients (48%), 15 of them with the metastases being restricted to the SN, whereas in group II, the SN were metastatic in 9 patients (28%), 5 of them with the positivity restricted to the SN. No false negative result (SN negative and other axillary nodes positive) was observed in group I and only one false negative result in group II which was related to a cancer with histological multiple invasive foci. Sensitivities were 100% and 90%, and negative predictive values were 100% and 95%, for groups I and II respectively. Subareolar injection of radiocolloid allows identification of SN in cases of unifocal and multiple cancer. The mean number of SN detected by the subareolar method is not significantly different, although higher, to that detected by peritumoral injection.

[Breast cancer: epidemiology, risk factors, screening]. / Cancer du sein: épidémiologie, facteurs de risque, dépistage.

Breast cancer is the most frequent cancer in women: more than 8 to 9% of women will develop a breast cancer during their life and the incidence rate is regularly increasing. Despite therapeutic improvements, breast cancer mortality still remains important and varying according to regions (five years survival: 62 to 80% for the last years). The risks factors analysis shows that a primary prevention of the major risks factors is not yet possible (genetic or endogenous hormonal risk). The chemoprevention is still is discussion and under investigation. For the moment, secondary prevention using screening is the only way to improve survival. The lead-time induced by the screening allows an earlier detection of breast cancers. The randomized trials have demonstrated a significant benefit on mortality and morbidity from breast cancer in women aged 50 to 69. So many countries started regional, pilot or national breast cancer screening programmes using mammography with a 2-year interval and specialized centers.

[Urinary complications during laparoscopy: a urachal diverticula injury]. / Complications urinaires de la coelioscopie: à propos d'une plaie d'un diverticule ouraquien.

The authors report a bladder injury during laparoscopic procedure. A laparotomy is performed immediately and shows an urachal anomaly with the bladder reaching the umbilic. One of the accessory trocars perforates the bladder in its unusual position. Surgical repair is made and the patient discharged without sequelae 12 days later. Rate of bladder injury increases with development of advanced laparoscopy as Burch and hysterectomy. Careful drainage with folley catheter during all laparoscopic procedures present greater than morbidity. Previous laparotomy may change the usual position of the bladder. Care must be taken in case of wall anomalies as in our observation. Per-operative suspicion of bladder injury (hematuria, presence of gas in the urinary catheter collection bag) can be proved with the injection of methylene blue in the folley catheter. Laparoscopic repair is possible for an experienced surgeon, associated with 10 days continuous urinary drainage and quinolone antibiotherapy. Morbidity of unknown bladder injury is great with some death-case reports. All diagnosis technique possible must be used to light these clinical situations, urinary peritonitis symptomatology is often non specific.

[Polycystic ovary and diazoxide. In vivo study]. / Ovaires polykystiques et diazoxide. Etude in vivo.

The suppression of hyperinsulinism with diazoxide (300 mg/d during 30 days) in a young woman with PCOS and hirsutism, hyperinsulinism and insulinoresistance was followed by a modification of plasma androgens. Testosterone (T) and free testosterone (fT) were reduced after ten days and then increased but always remained below the baseline level. DHEAS had increased 200% by day 10, and 3 alpha-adiol G to three times its basal value by day 20. These modifications were constant during the treatment. fT decrease was secondary to reduction of hyperinsulinism which was followed by an increase of TeBG and a modest and transient reduction of androgen theca cells production. DHEAS increase was due to hyperinsulinism suppression which stimulated adrenal 17-20 lyase activity. 3 alpha-adiol G increase was concomittant, and can be considered as an index of adrenal androgen secretion.
