RESUMO

OBJECTIVES: The aim of the present study was to evaluate the impact of obesity on reproductive and oncologic outcomes on the success of fertility-sparing management. METHODS: This retrospective multicenter cohort study included women treated conservatively for atypical hyperplasia (AH) and endometrial cancer (EC) to preserve fertility. Five inclusion criteria were defined: (i) the presence of AH or grade 1 EC confirmed by two pathologists; (ii) adequate radiological examination before conservative management; (iii) available body mass index (BMI) at the beginning of treatment; and (iv) a minimum follow-up time of six months. RESULTS: Forty patients fulfilled the inclusion criteria (17 had EC, and 23 had AH), mean age and BMI were 33 years and 29kg/m(2) respectively. Among the 15 obese patients, after medical treatment, 10 patients responded (67%) and three relapsed, whereas in the 25 non-obese patients, 19 responded (76%) and three relapsed (p=0.72). The overall pregnancy rate and follow-up time were 35% and 35 months respectively. Among the 15 obese patients, after medical treatment, two patients became pregnant, whereas in the 25 non-obese patients, 12 became pregnant (p=0.04). CONCLUSION: Despite similar response and recurrence rates, our results suggest that fertility-sparing management for AH and EC is associated with a lower probability of pregnancy in obese patients.

RESUMO

The aim of this study was to evaluate the advantages of the two-step embryo transfer (ET) strategy combining a day 2/3 ET with a day 5/6 blastocyst transfer. In an observational comparative study, 400 infertile women were enrolled from two assisted reproductive technology (ART) units according to inclusion criteria: age below 42 years and at least three embryos obtained on day 2 thus allowing an extended in vitro culture. Two groups were defined according to the ET strategy adopted: group 1 had a two-step ET; and group 2 had a day 2/3 ET with (subgroup 2a) or without (subgroup 2b) blastocysts cryopreserved on day 5/6. Live birth rate was significantly higher in group 1 than in subgroups 2a and 2b (36.5% versus 29.4% and 13.4%, respectively; p < 10(-3)). Multiple pregnancy rates were comparable between groups. After adjusting on major prognostic factors, the two-step ET strategy was still associated with a significantly higher live birth rate than the day 2/3 ET (OR = 2.23; 95% CI: 1.32-3.77). The two-step ET provides better live birth rates than the cleavage-stage ET. It does not increase multiple pregnancy rates if the number of embryos transferred is limited. It also prevents cycle loss when embryos fail to develop into blastocysts.

RESUMO

The utility of sperm DNA testing remains controversial. However, it may be helpful in couples with unexplained failures of multiple assisted reproductive techniques and/or recurrent abortions. This study analysed 10,400 spermatozoa of 26 patients for sperm-head morphology with high-magnification microscopy, DNA fragmentation and sperm chromatin decondensation. A significant negative correlation was demonstrated between sperm-parameters and abnormal sperm-head morphology as assessed by high magnification (score 0 according to this study's classification): concentration (r=-0.41; P=0.03), motility (r=-0.42; P=0.03), morphology (r=-0.63; P=0.0008). No correlation was found with DNA fragmentation. However, the sperm chromatin-decondensation rate of score-0 spermatozoa was twice as high as the controls (19.5% versus 10.1%; P<0.0001). This observation suggests that score-0 spermatozoa should not be selected for intracytoplasmic sperm injection.

RESUMO

The consequences of hepatitis B virus (HBV) infection for fertility are still unclear. Spermatozoa with decreased motility have been reported in HBV-infected patients. It has been demonstrated in vitro that HBV S protein has adverse effects on human sperm function with consequences for fertilization. In a case-control study design, 32 IVF cycles in couples with male HBV infection were compared with 64 cycles in non-infected couples, matched for age, time period, cycle rank and sperm parameters on the day of oocyte retrieval. Sperm motility before selection was significantly reduced in the HBV group (36.3 ± 11.6% versus 45.3 ± 14.4%,P = 0.003). A low fertilization rate (LFR) was more frequently observed in the HBV group (34.4% versus 15.6%, P = 0.036) and was associated with a decreased number of embryos available for transfer, although embryo quality on day 2 or 3 was not different.Implantation and pregnancy rates were comparable between groups. This study shows that HBV has a deleterious effect on sperm motility in vivo and that couples whose male partner is infected have a higher risk of LFR after IVF, a risk which is independent from the initial sperm motility.

RESUMO

STUDY OBJECTIVE: This study was undertaken to ascertain whether the incidence of spontaneous pregnancy is increased in infertile women with deep and intraperitoneal endometriosis undergoing extensive surgery compared with those undergoing only intraperitoneal surgery. DESIGN: Retrospective case control study (Canadian Task Force classification II-1). SETTING: University teaching hospital. PATIENTS: Infertile women under the age of 40 years with deep and intraperitoneal endometriosis and no other associated major infertility factors. Only patients with at least 1 year of postoperative follow-up were included. INTERVENTIONS: Intraperitoneal surgery only (group 1) or extensive surgery (group 2) according to a shared decision-making approach. MEASUREMENTS AND MAIN RESULTS: Among the 34 women in group 1, 6 became pregnant, compared with 8 of the 41 women who had extensive surgery (12-month cumulative probabilities, 24.8% and 11.4%, respectively, and 24-month cumulative probabilities, 24.8% and 23.2%, respectively; p = .82). Perioperative surgical complication rate was higher in group 2 (6/41 versus 0/34; p = .02). CONCLUSION: Extensive surgery for intraperitoneal and deep endometriosis in infertile women does not modify global fertility outcome but is associated with a higher complication rate.

RESUMO

INTRODUCTION: According french legislation, sperm freezing/thawing procedures are used to prevent ART contaminations in couple with HIV-1 infected men. We determined sperm nuclear fragmentation rate before and after selection and freezing/thawing in HIV-1 14 patients. METHODS: Two groups of patients were studied: 20 control patients with normal sperm (group 1) and without viral infection and 20 fertile treated HIV-1 patients (group 2). DNA fragmentation was evaluated using terminal uridine nick end labeling, before and after gradient selection, and after cryopreservation and thawing procedures. RESULTS: DNA fragmentation rates in fresh semen were increased in HIV patients (6.38% vs 3.39%) (p < 0.05) compared with control patients. After sperm migration, fragmentation rates were significantly lower (p < 0.0001) in the two groups compared with fresh sperm rates. After freezing/thawing, values were similar to those of fresh semen with an increased rate (p < 0.01) for HIV-1 patients, with respectively 3.40% and 5.18% rates in control and infected patients. HIV-1-infected patients treated by antiretroviral therapy showed a significant increase in sperm DNA fragmentation in fresh sperm and also after freezing/thawing procedures, but these two fragmentation rates were not significantly different. CONCLUSION: So, freezing/thawing procedures do not seem to impair sperm DNA and preserve probability of conception for couples with HIV-1 infected men.

RESUMO

BACKGROUND: Pregnancy is associated with decreased hypnotic requirement, allegedly related to progesterone. However, the effects of pregnancy and progesterone on propofol requirement have not been thoroughly investigated. We conducted this study to determine whether propofol dose and predicted effect-site concentration for loss of consciousness (LOC) during induction of anesthesia, and eye opening during emergence from anesthesia, are decreased during early pregnancy. We also investigated whether blood progesterone was correlated with propofol dose and effect-site concentration for LOC. METHODS: We studied 57 ASA I-II women patients undergoing elective termination of pregnancy and 55 control patients undergoing transvaginal oocyte puncture for in vitro fertilization. Anesthesia was induced by administration of a 1% propofol infusion at 200 mL/min. Propofol dose and calculated effect-site concentration (Schnider model) were recorded at the time of LOC during induction. We also calculated effect-site concentration at the time of eye opening upon emergence from anesthesia. Blood progesterone was measured after surgery. RESULTS: Mean (+/-1 SD) propofol dose at LOC was significantly reduced in the pregnant patients compared with the nonpregnant control patients (108.57 +/- 20.04 vs 117.59 +/- 17.98 mg, respectively; P = 0.014). Similarly, the calculated propofol effect-site concentration at LOC was significantly lower in the pregnant patients than the nonpregnant control patients (4.59 +/- 0.72 vs 5.01 +/- 0.64 microg/mL, respectively; P = 0.0014). There was no difference in the calculated effect-site concentration on eye opening upon emergence. No significant relationship was observed between blood progesterone and propofol dose or calculated propofol effect-site concentration at LOC. CONCLUSION: Propofol dose and predicted propofol effect-site concentration at LOC are decreased during early pregnancy. Progesterone does not explain this result.

RESUMO

OBJECTIVE: To investigate the relationship between serum P levels on the day of hCG administration and pregnancy outcomes in patients undergoing IVF. DESIGN: Retrospective study. SETTING: Teaching hospital. PATIENTS: A total of 1022 IVF-ICSI cycles, frozen embryo transfer excluded. INTERVENTION(S): Patients-all types of responder - underwent IVF with agonist or antagonist protocols. Clinical outcomes of IVF were analyzed according to plasma P levels. MAIN OUTCOME MEASURE(S): Ongoing pregnancy rates. RESULTS: We proposed a serum P level of 1.57ng/ml on day of hCG as a threshold for all types of responders and all protocols combined. Ongoing implantation rates were not affected by elevated progesterone. Live birth rate was inversely associated with serum P levels on day of hCG and more miscarriages were associated with P>1.57ng/ml. We have not found the progesterone>1.57ng/ml on the day of hCG as a prognostic factor for pregnancy. CONCLUSION(S): Elevated P level on the day of hCG administration negatively influence live birth rate and is correlated to an increase of miscarriage. The detrimental effect of P elevation on pregnancy seems not to be related substantially to endometrium receptivity. Thus, despite a comparable clinical pregnancy rate and an initial implantation rate, we demonstrate more spontaneous abortion and it would seem that the effect of progesterone is later.

RESUMO

Evidence is cumulating on the adverse health effects of environmental exposures on health of the fetus and the childbearing mothers. Among mother's conditions, gestational diabetes mellitus has been considered rarely in spite of its importance for both mother and child. We determined the role of maternal exposure to lead (Pb), cadmium (Cd) and manganese (Mn) to gestational diabetes mellitus (GDM) on diagnosed GDM and impaired glucose tolerance (IGT) in diabetes-free mothers from the French EDEN mother-child cohort. 623 pregnant women without pre-existing diabetes were included in the study. GDM and IGT were diagnosed by a gynecologist during consultations after blood analysis. Pb, Cd and Mn were measured in second-trimester blood samples. Associations between ln-transformed concentrations of metals and GDM and IGT respectively were examined using multiple logistic regression analysis adjusted for potential confounders. The prevalences of GDM and IGT were 7.1% and 10.1% respectively. After adjustment for confounders, Cd was statistically related to having had a diagnosis of GDM or IGT (Adjusted Odds-Ratio (AOR): 1.61, 1.05-2.48), and Pb to GDM at borderline significance (AOR: 1.65, 0.82-3.34). Our findings add to the growing evidence supporting the role of maternal exposure to heavy toxic metals that persist longtime in the environment as a risk factor for GDM.

RESUMO

OBJECTIVE: To evaluate the feasibility and the complication rate of vaginal hysterectomy in benign uterine pathology (except for uterine prolapse) among patients without previous vaginal delivery. METHODS: A review of the medical records in patients without previous vaginal delivery who underwent hysterectomies between January 1995 and June 2004 was carried out. Patients were divided into two different groups: group 1 included patients with first-intention abdominal hysterectomy; group 2 included patients with vaginal approach further stratified into 2a without and 2b with laparoscopic assistance. RESULTS: Three hundred patients without previous vaginal delivery underwent hysterectomy during this period. Vaginal hysterectomy was planned in 75.7% of cases. Success rate for planned vaginal hysterectomies was 92.1%. The mean weight of uteri extracted by vaginal and abdominal approaches were 326 g and 1,047 g, respectively (P<.001). The mean operative time was significantly longer in the laparoscopic-assisted approach (160 minutes) than in the abdominal approach (120 minutes), and significantly shorter in exclusively vaginal (75 minutes) than in other procedures (P<.001). The use of the laparoscopic assistance in hysterectomy decreased significantly over the period of the study (P<.001). The mean duration of hospital stay was significantly shorter in group 2 than in group 1 (3.8 days compared with 6.2 days, P<.001), but no differences were noted between subgroups 2a and 2b. CONCLUSION: Vaginal hysterectomy should not be contraindicated in patients lacking previous vaginal delivery. In these particular patients, most of the procedures can be performed by vaginal approach, with the benefit of limiting the costs and the duration of hospital stay.

RESUMO

We aimed to describe 3D scapular kinematics and scapulohumeral rhythm (SHR) in glenohumeral (GH) osteoarthritis shoulders compared to unaffected shoulders and to compare the abnormal scapular kinematic schema for GH osteoarthritis with that for frozen shoulder. Thirty-two patients with stiff shoulder (16 with GH osteoarthritis and 16 with frozen shoulder) performed maximal arm elevation in two planes, sagittal and frontal. Scapular rotations and humeral elevation of the affected and unaffected shoulders were measured by the Polhemus Fastrak electromagnetic system. Patients with GH osteoarthritis were older, had longer disease duration (p<0.001) and less restricted humeral elevation in the frontal plane (p=0.01). Protraction was significantly lower for the affected shoulders except for arm elevation in the frontal plane in the GH osteoarthritis group. Furthermore, protraction was lower with frozen shoulder than GH osteoarthritis during arm elevation in the frontal plane. Scapular lateral rotation and SHR were significantly higher for the affected shoulders in both groups whatever the plane of elevation. SHR showed a fair to moderate negative correlation with maximal humeral elevation in both groups and appears to be higher with frozen shoulder than GH osteoarthritis. In addition, SHR of the affected shoulder showed a fair to moderate correlation with disease duration only with GH osteoarthritis. Scapular tilt did not differ between affected and unaffected sides and was not influenced by type of disease. In conclusion, the increased scapular lateral rotation described in frozen shoulder is also observed in GH osteoarthritis. SHR of the affected shoulder is inversely related to severity of limitation of shoulder range of motion, which suggests a compensatory pattern.

RESUMO

UNLABELLED: Manganese (Mn) is widely distributed in the biosphere but occurs in only trace amounts in animal tissues. Although Mn deficiency and toxicity both have pathological consequences, the underlying biochemical lesions have not been well defined. In vitro studies suggest that transport proteins are affected by Mn, lead (Pb), and selenium (Se). Among these transport proteins, the calmodulin-regulated calcium pump (Ca(2+)Mg(2+)ATPase) could be inhibited by Mn. In order to understand Mn biochemical pathways, we examined the relationships between Mn blood levels and red blood cell Ca-pump activity among 248 mothers and newborns, environmentally exposed to Mn, Pb, and Se. POPULATION AND METHODS: 248 mother-newborn pairs were recruited at Robert Debré University Hospital (Paris). Blood Mn and Pb concentrations were measured by absorption spectrophotometry. Se was measured by fluorometric method. Red blood cell membrane suspensions were obtained for Ca-pump activity measurements. Linear and quadratic regression models and Pearson correlation were performed. RESULTS: A non-linear parabolic relationship between maternal Mn blood levels and newborn Ca-pump activity was discovered from the analysis of the observed data. The peak level of maternal Mn that corresponded to a maximal activity of the newborn Ca-pump was estimated at 23.9 microg/l with a 95% confidence interval of 17.6 to 32.4 microg/l. An inhibition of this enzyme was observed at low and high levels of maternal Mn. The relationships between the newborn Ca-pump activity and maternal Se and Pb levels became non-significant after adjustment on all the co-factors included in the final model. CONCLUSION: Maternal environmental exposure to Mn, as reflected by maternal blood levels of this metal, is associated with a reduced activity of newborn erythrocyte Ca-pump in a non-linear pattern. Mn levels between 17.6 and 32.4 microg/l in maternal blood probably correspond to the optimal physiological concentration for the metabolism of this enzyme in newborns.

RESUMO

OBJECTIVE: To compare the efficacy of assisted reproductive technology (ART) in women infected with human immunodeficiency virus type 1 (HIV-1) versus HIV-negative controls. DESIGN: Retrospective case-control study. SETTING: University hospital ART unit. PATIENT(S): Eighty-two women infected with HIV-1 and 82 women as seronegative controls. INTERVENTION(S): Ovarian stimulation, oocytes retrieval, standard in vitro fertilization (IVF) or intracytoplasmic sperm injection, embryo transfer. MAIN OUTCOME MEASURE(S): Clinical pregnancies and live-birth rates. RESULT(S): After oocyte retrieval, all women infected with HIV-1 infected were matched 1:1 to HIV-negative controls according to the following criteria: date of ART attempt, age, parity, main cause of infertility, ART technique, and rank of attempt. Only the first IVF cycle during the study period was considered for each couple. We found no statistically significant differences between the two groups for ovarian stimulation data, fertilization rate, or average number of embryos transferred. The clinical pregnancy rate per transfer was statistically significantly lower for the cases compared with the controls (12% vs. 32%), as were the implantation rate (10% vs. 21%) and the live-birth rate (7% vs. 19%). CONCLUSION(S): In one of the largest studies to pair six factors that influence the results of ART, HIV infection in women was associated with poorer outcomes after ART. These results suggest that women with controlled HIV-1-infection should be counseled not to delay ART in cases of self-insemination failure or other causes of infertility. Fertility preservation by vitrification of oocytes in women whose pregnancy should be delayed may be an important future consideration.

RESUMO

Following boron intake, multiple effects have been observed in animal experiments. However, human data is lacking, and no data is available on the ability of boron to accumulate in fetal tissues. Positive responses in animal species suggest that developmental toxicity may be an area of concern in humans, following exposure to boron. Two hypotheses have seemed to account for the multiple effects described in scientific findings. One hypothesis is that boron is a negative regulator that influences a number of metabolic pathways by competitively inhibiting some key enzyme reactions. The other hypothesis is that boron has a role in ionic membrane transport regulations. To better understand boron potential toxicity, the present study examined the relationship between boron exposure and some key enzymes, well-known for their affinity for mineral elements, such as delta-aminolevulinic acid dehydratase (ALA-D), and two fundamental enzymes having a role in ionic membrane transport regulations (Ca-pump and Na(+)K(+)-ATPase). We investigated the potential effects of an environmental boron exposure on the activity of these enzymes in an urban population of 197 "normal" newborns. Environmental boron exposure was assessed in placental tissue. Because of the well-known inhibiting effect of lead on these enzymes, cord blood and placental lead were also analyzed. After adjustment for potential confounders, including lead, placental boron levels were negatively significantly correlated to ALA-D activity while Ca-pump and Na(+)K(+)-ATPase activities did not seem to be affected by the level of boron exposure. Given boron's ability, as a Lewis acid, to complex with hydroxyl groups, we suggest that such a mechanism would explain the inhibiting effect of boron on ALA-D.

RESUMO

Multiple gestations have a significantly increased incidence of preterm labor and preterm rupture of membranes. In this case, a 32-year-old woman had a car accident with preterm labor at 19 weeks' gestation. A vaginal delivery of the presenting triplet followed. After conservative management, the second and third triplets were delivered by cesarean section after a 70-day delay. A review of the literature was done.

RESUMO

OBJECTIVE: Evaluation of the efficacy and the safety of the TVT as a surgical treatment for the female stress incontinence. MATERIAL AND METHODS: Prospective non-randomized study undertaken between January 1999 and December 2000 concerning 40 women admitted to the Hotel-Dieu de France Hospital, with specific inclusion criteria. The surgical procedure used is the TVT as described by Ulmsten. Patients' evaluation is made through valid criteria shown in the literature. RESULTS: The mean follow-up is 12 months. The mean operation time is 37 minutes. The mean duration of hospitalization is 2.6 days. Postoperative complications were transient urinary retention in 17.5% of cases, and lower urinary tract infection in 10% of patients. One case of bladder perforation was noted. The mean difference between the numbers of protections used daily before and after TVT is 2.03 +/- 1.89 (p < 10(-4)). 87.5% of patients were totally and objectively continent. The mean post-voiding residue is 85 +/- 91 ml. Bladder instability symptoms were significantly reduced (RR = 0.37). 97.5% of patients are cured or improved by the operation. CONCLUSION: The TVT is an effective procedure and easy to perform. The results obtained so far are promising. The failure rate is about 2.5%. A standardization of the indications is preferred for future studies.

RESUMO

OBJECTIVE: To evaluate the success rate of laparoscopic neosalpingostomy and the factors affecting the results in terms of intrauterine pregnancy (IUP), delivery (DEL), and ectopic pregnancy (EP). DESIGN: Retrospective analysis of prospectively recorded data. SETTING: Private practice. PATIENT(S): A total of 434 consecutive infertile patients from 21 to 42 years old with a follow-up of more than 10 years. INTERVENTION(S): Laparoscopic neosalpingostomy. MAIN OUTCOME MEASURE(S): Intrauterine pregnancy, delivery, and EP rates obtained without requiring IVF. Statistical analysis includes univariate and multivariate analysis and crude and actuarial success rates. RESULT(S): Just over one-quarter (28.8%) of the patients presented an IUP, 24.4% delivered, and 9% presented with an EP. The 5-year actuarial rate of delivery was 37%. This rate was largely dependent on the tubal stage (stage 1: 53.1%; stage 2: 43.1%; stage 3: 24.0%; stage 4: 23.1%). Forty-three percent of the expected IUPs started in the first year, and 75% started in the first two years. Multivariate analysis found some poor-prognosis patterns for tubal stage 3 (odds ratio [OR] 0.24), tubal stage 4 (OR 0.28), repeated neosalpingostomy (OR 0.168), previous EP (OR 0.202), severe adhesion stage (OR 0.211), and positive chlamydial serology (OR 0.515). Eversion with sutures provides nonsignificantly better results (OR 1.63) compared with eversion with coagulation. CONCLUSION(S): Neosalpingostomy must not be proposed in selected cases according to the tubal stage, adhesion stage, and chlamydial serology. When neosalpingostomy is performed, fimbrial eversion with sutures provides slightly better results.

RESUMO

INTRODUCTION: Colouterine fistula is a very rare condition; most cases described in the literature are secondary to complications of diverticulitis in elderly patients. CASE PRESENTATION: We report the case of a 34-year-old African woman who presented with a colouterine fistula secondary to polymyomectomy, which was diagnosed in the setting of severe endometritis. She had a Hartmann procedure and abundant irrigation of her abdominal and uterine cavities followed by placement of a double drainage in order to preserve fertility. This is the first case of a conservative management of the uterus in such conditions. CONCLUSION: Conservative surgery in colouterine fistula should be discussed as an alternative to hysterectomy in young infertile women.

RESUMO

BACKGROUND: Hepatitis delta virus (HDV) is a satellite of HBV and needs this latter's envelope for its morphogenesis and propagation. An estimated 5-20% of HBV-infected patients are also infected with HDV. No studies have ever been performed to determine the presence of HDV in follicular fluid (FF) and semen of HDV-infected patients. OBJECTIVES: To investigate the presence of HDV markers in the FF or in the semen of two HDV-infected patients. DESIGN: Two unrelated HDV-infected patients, a woman and a man pursuing in vitro fertilization (IVF), participated in this study. FF was collected after analysis of oocyte retrieval. The supernatant of seminal plasma (SP) and the final pellet (FP) were fractionated from freshly ejaculated semen. Serological and molecular markers of HDV infection were searched for in these different samples. RESULTS: The woman was infected with an HDV-7 genotype strain and her HDV plasma viral load (VL) was 6 log copies/mL. HDV antibodies and RNA were also detected in the FF, however the RNA VL value there was lower by more than 4 log. The man was infected with an HDV-1 strain and his plasma VL was 6.7 log copies/mL. Total anti-HDV antibodies were positive in the serum, in the SP and in the FP, while IgM were detected only in the serum. However, HDV RNA was negative in the SP and in the FP. CONCLUSION: HDV markers can be found in the follicular fluid or in the semen of infected patients.
