[Is vaginal delivery possible for patients with myomectomy? Results of a monocentric study]. / Après myomectomie, les patientes ont-elles le droit d'accoucher par voie basse ? Résultats d'une étude monocentrique.

OBJECTIVE: To compare delivery outcomes according to the scar: myomectomy versus low-segment transverse cesarean. METHODS: A retrospective cohort study was performed in a university type 3 service between 1st January 2006 and 1st January 2012. We compared 18 women who gave birth after myomectomy (exposed group) to 72 women who gave birth after cesarean section (non-exposed group). Women younger than 43 years who underwent laparotomy or laparoscopic myomectomy were included. The primary endpoint was the rate of vaginal delivery. The route of delivery, the rate of uterine rupture, complications of delivery and neonatal outcome were studied. RESULTS: The acceptance rate of vaginal delivery was 55.6% after myomectomies versus 84.7% after cesarean section (P=0.005). The success of vaginal birth was 88.9% after myomectomy versus 73.9% after cesarean (NS). No uterine rupture has occurred after myomectomy against three sub-peritoneal rupture after cesarean. The occurrence of post-partum hemorrhage was not significantly different between the 2 groups (11.1% among exposed group versus 6.9% in the non-exposed group). The cesarean section rate was even higher than the number of hysterotomy was great (P=0.0047). CONCLUSION: This study seems to show that vaginal birth after myomectomy is possible with a success rate similar to vaginal birth after cesarean section.

[Risk of uterine synechiae following uterine compression sutures during postpartum haemorrhage]. / Risque de synéchie utérine après capitonnage utérin pour hémorragie du post-partum.

OBJECTIVES: Uterine compression sutures are highly successful conservative surgical techniques used to treat severe postpartum haemorrhage. These methods can induce subsequent uterine synechiae. To determine this risk of synechiae after conservative uterine compression sutures, which may induce further fertility problems. PATIENTS AND METHODS: We retrospectively reviewed the medical and pathological records of the patients who underwent uterine compression sutures for severe postpartum haemorrhage between January 2003 and March 2013 in a French University Hospital. The Cho's, the B-Lynch's and the Hayman's techniques have been used. The results of the hysteroscopies were detailed. RESULTS: Among the 25 patients included, the B-Lynch or the Hayman's techniques have been used in 13 cases (52%). The Cho's technique has been performed alone for 5 patients (20%) and both techniques have been practiced in 7 situations (28%). In 17 cases (68%), some vascular sutures have been associated and, for 7 patients (28%), a vascular embolisation had been performed before the uterine compressive sutures. Only 19 patients underwent a diagnostic hysteroscopy and among them 13 had a normal uterine cavity (68%), 3 of them had uterine synechiae (16%) and 3 had placental retention (16%). Synechiae and retention have all been successfully removed by operative hysteroscopy. DISCUSSION AND CONCLUSION: The compressive techniques can induce uterine synechiae, which may impair subsequent fertility.

[Surgical treatment for female stress urinary incontinence by transobturator tape (outside in). Study of 70 cases]. / Cure chirurgicale de l'incontinence urinaire d'effort de la femme par bandelette transobturatrice (de dehors en dedans). Etude de 70 cas.

OBJECTIVES: To evaluate the feasibility, the efficacy and the innocuousness of suburethral transobturator support using multifilament polypropylene transobturator tape (TOT) inside out for stress urinary incontinence in women. MATERIALS AND METHODS: The study concerns 70 patients representing our team's first experience of this technique. The inclusion criterion was persistent SUI despite perineal rehabilitation. There were no exclusion criteria. Among the 70 patients, 22 (31%) presented with associated genital prolapse. Mean parity was 2.6 (extremes ranging from 0 to 6). Thirty-five patients were menopaused (50%), of whom 12 (34%) were under hormone replacement therapy. We retained five judgement criteria to evaluate this surgical act: duration of surgery and hospitalisation, per- and postoperative complications and functional results on SUI (via a telephone questionnaire). RESULTS: The rate of positive results (healing or improvement) was 84% with a mean follow-up of 14.5 months. The rate of peroperative complications was very low: 1.4% (only one case of bladder injury). The mean duration of surgery was 23 minutes. The mean duration of hospitalisation in the case of isolated TOT was 1.25 days. CONCLUSION: The transobturator approach is a feasible, safe and efficient short-term surgical technique. Results inferior to those observed in the literature are probably due to the learning curve in a university hospital unit. None of the preoperative data (age, parity, body mass index, history of SUI treatment or hysterectomy, hormonal status, associated prolapse, mean urethral closure pressure, clinical vesical hyperactivity syndrome) appears to influence results; however, the study strength is poor due to the small study population.

[Laparoscopic management of pelvic mass in pregnancy]. / Prise en charge coelioscopique des masses latéro-utérines pendant la grossesse.

OBJECTIVES: To determine the feasibility, safety and limiting factors of laparoscopic management of pelvic mass in pregnancy. MATERIAL: and methods. During a 10-year period, 21 laparoscopic procedures were performed in patients with pelvic masses in pregnancy after exclusion of appendicitis and ectopic pregnancy. Laparoscopic surgery was done during the first trimester of pregnancy in 8 cases, the second trimester in 12 cases and the third trimester in one case. All the procedures were performed with general anesthesia and the laparoscopic cystectomies were performed with the intraperitoneal technique. RESULTS: The indications were: persistent or sonographically abnormal ovarian cyst (12 cases), torsion of ovarian cyst (5 cases), and symptomatic pelvic mass (4 cases: 2 painful cysts and 2 infarction of fibroma). One borderline tumor were discovered. The laparoscopic procedure could not be performed in two cases due to difficulty of access to the lesion. No patient encountered complications during the intra- and post-operative periods. The mean hospital stay was 4.5 days. The outcome of the pregnancy was normal in all cases. CONCLUSION: Laparoscopic management of pelvic masses in pregnancy by an experienced team, is a safe and effective procedure.

[Multiple Ebola virus haemorrhagic fever outbreaks in Gabon, from October 2001 to April 2002]. / Plusieurs epidémies de fièvre hémorragique due au virus Ebola au Gabon, d'octobre 2001 a avril 2002.

Outbreaks of Ebola virus haemorrhagic fever have been reported from 1994 to 1996 in the province of Ogooué Ivindo, a forest zone situated in the Northeast of Gabon. Each time, the great primates had been identified as the initial source of human infection. End of November 2001 a new alert came from this province, rapidly confirmed as a EVHV outbreak. The response was given by the Ministry of Health with the help of an international team under the aegis of WHO. An active monitoring system was implemented in the three districts hit by the epidemic (Zadié, Ivindo and Mpassa) to organize the detection of cases and their follow-up. A case definition has been set up, the suspected cases were isolated at hospital, at home or in lazarets and serological tests were performed. These tests consisted of the detection of antigen or specific IgG and the RT-PCR. A classification of cases was made according to the results of biological tests, clinical and epidemiological data. The contact subjects were kept watch over for 21 days. 65 cases were recorded among which 53 deaths. The first human case, a hunter died on the 28th of October 2001. The epidemic spreads over through family transmission and nosocomial contamination. Four distinct primary foci have been identified together with an isolated case situated in the South East of Gabon, 580 km away from the epicenter. Deaths happened within a delay of 6 days. The last death has been recorded on the 22nd of March 2002 and the end of the outbreak was declared on the 6th of May 2002. The epidemic spreads over the Gabon just next. Unexplained deaths of animals had been mentionned in the nearby forests as soon as August 2001: great primates and cephalophus. Samples taken from their carcasses confirmed a concomitant animal epidemic.

[Advantages of the in vivo HRT2 corneal confocal microscope for investigation of the ocular surface epithelia]. / Intérêt du microscope confocal cornéen in vivo HRT2 pour l'étude de l'épithélium cornéo-conjonctival.

PURPOSE: To show the advantages of the in vivo HRT2 confocal microscope corneal module for studying the superficial and peripheral corneal and conjunctival epithelia. MATERIAL AND METHODS: We examined 15 patients whose superficial cornea was healthy and ten patients with keratoconjunctivitis sicca and/or rosacea. Some conjunctival imprints where taken on patients with superficial ocular disease and examined by immunofluorescence. RESULTS: We found superficial corneal epithelial cells, corneoconjunctival Langerhans and dendritic cells, goblet cells, limbic epithelial junction, new blood vessels, as well as deeper corneal structures such as Bowman's membrane, keratocytes, corneal nerves, and endothelium. We also observed pathological corneal epithelium in keratoconjunctivitis sicca and substantial inflammatory and vascular changes in rosacea. In two cases of stem cell deficiency associated with rosacea, we observed goblet cells in the corneal epithelium. An interesting anatomical-clinical parallelism between in vivo confocal microscopy images and those obtained by ex vivo immunofluorescence was observed. DISCUSSION: Central corneal pictures after explorations by in vivo HRT2 confocal microscopy are similar to those obtained with standard confocal microscopy. But conjunctiva, peripheral cornea and limbus are better examined at the surface and at medium depth with the HRT2. Diagnosis and therapy of superficial corneoconjunctival and limbal diseases are therefore made easier in vivo.

Disease-modifying anti-osteoarthritic drugs: current therapies and new prospects around protease inhibition.

Although osteoarthritis is commonly found in the elderly, the pathophysiological mechanisms of this degenerative disease are still poorly understood. Among the many factors leading to cartilage degradation, the proteolytic activity of a panel of enzymes seems to play a major role, leading to the cleavage of collagen and proteoglycans, the two main components of cartilagenous matrix. Aspartic, cysteine, serine and metalloproteases have been detected in or around the osteoarthritic articulation and their enzymatic activity is reviewed here. The cartilage-sparing properties of the respective inhibitors are listed, giving rise to the hypothesis that some of these compounds could be developed as chondroprotective agents.

A national survey of human Mycobacterium bovis infection in France. Network of Microbiology Laboratories in France.

OBJECTIVE: To evaluate the role of Mycobacterium bovis in the epidemiology of human tuberculosis in France. DESIGN: A national survey in France in 1995 using a questionnaire mailed to all French microbiological laboratories performing mycobacteria cultures. RESULTS: M. bovis was isolated in 38 out of 7075 cases of bacteriologically confirmed tuberculosis (0.5%) notified to the National Reference Centre (CNR) in 1995, resulting in an incidence of 0.07 per 100,000 population. Incidence rates increased with age, and were the highest among patients of 75 years or more (range 0.02-0.33/100,000). Two cases of tuberculosis due to M. bovis were reported in foreign-born children who had come to France for treatment of their disease. No cases were reported among French-born children. The site of tuberculosis was pulmonary in 17 cases, extra-pulmonary in 14, both pulmonary and extra-pulmonary in one, and unknown in six. Extra-pulmonary sites were more frequent in older patients, and pulmonary sites more frequent in younger patients. Two patients were coinfected with the human immunodeficiency virus. Occupational exposure was identified in 13 cases and ingestion of non pasteurised milk in three. In addition, 11 patients had a possible risk of exposure related to their country of birth, family contact or occupation. CONCLUSION: In France, the 0.5% proportion of human tuberculosis due to M. bovis is similar to that of other developed countries. The higher incidence of the disease among older people is likely to reflect the efficacy of the control measures for tuberculosis in cattle.

Role of nitric oxide in the regulation of the mechanical properties of peripheral conduit arteries in humans.

Whether nitric oxide (NO) contributes to the regulation of the mechanical properties of large arteries in humans is not known. We measured the effect of local administration of the inhibitor of NO synthesis N(G)-monomethyl-L-arginine (L-NMMA; 1 and 4 micromol x L[-1] x min[-1] for 5 minutes) and acetylcholine (3 and 30 nmol x L[-1] x min[-1] for 3 minutes) on radial artery diameter and wall thickness in 11 healthy volunteers using an echo-tracking system coupled to a measurement of radial blood flow (Doppler) and arterial pressure. At the highest dose, L-NMMA reduced radial blood flow but surprisingly decreased incremental elastic modulus (from 1.36+/-0.22 to 1.00+/-0.22 kPa x 10[3]; P<.05) and increased arterial compliance (from 3.20+/-0.46 to 4.07+/-0.45 m2 x kPa x 10(-8), P<.05), without affecting radial artery internal diameter, wall thickness or midwall stress, thus reflecting a decrease in vascular tone. Acetylcholine decreased incremental elastic modulus (from 1.27+/-0.08 to 0.88+/-0.07 kPa x 10[3]; P<.05) and increased arterial diameter, radial blood flow, and compliance (from 2.82+/-0.16 to 5.30+/-0.62m2 x kPa x 10[-8]; P<.05). These results demonstrate in vivo that NO is involved in the regulation of the mechanical properties of large arteries in humans. However, the effects of L-NMMA, ie, a decrease in arterial wall rigidity and an increase in arterial compliance, which occur in the absence of any changes in blood pressure or arterial geometry, suggest that inhibition of NO synthesis is associated in humans with a paradoxical isometric smooth muscle relaxation. This effect could be due to the development of compensatory vasodilating mechanisms after NO synthesis inhibition.

Evaluation of the determinants of flow-mediated radial artery vasodilatation in humans.

The relative importance of the early peak response during hyperaemia and of the duration of the hyperaemic phase (t1/2: blood flow velocity half time and AUCt1/2: area under the curve of flow velocity at t1/2) in the magnitude of the flow-dependent vasodilatation of the radial artery was determined in humans. Radial artery diameter was measured continuously in 18 healthy volunteers using an echo-tracking system coupled to a Doppler device for the measurement of the radial blood flow. In 9 subjects, arterial parameters were measured at baseline and during 3 hyperaemic tests performed after 2, 5 or 10 minutes of ischaemia. Reproducibility of the measured parameters was studied in 9 other subjects. Radial artery diameter, AUCt1/2 and t1/2 increased proportionally with the duration of ischaemia. In contrast, the peak flow response was already maximal after 5 minutes of ischaemia. The regression analysis showed that the best fit model after stepwise analysis only included t1/2 (r = 0.85, p < 0.001). There was no correlation between the peak flow values and the duration of hyperaemia (r = 0.29, p = 0.14). These results demonstrate that conduit arteries postischaemic flow-dependent vasodilatation in humans is both determined by the peak value and by the duration of the hyperaemic phase and suggest that these two components must be considered when comparing this index of NO release between different groups of subjects.

New prolyl endopeptidase inhibitors: in vitro and in vivo activities of azabicyclo[2.2.2]octane, azabicyclo[2.2.1]heptane, and perhydroindole derivatives.

A series of potent and selective prolylendopeptidase (PEP) inhibitors of the alpha-keto heterocyclic type has been obtained by replacing the classical central proline of 1-[1-(4-phenylbutanoyl)-L-prolyl]pyrrolidine (SUAM 1221,3) by non-natural amino acids PHI, ABO, and ABH. These 4-phenylbutanoyl side-chain-containing inhibitors exhibited potent in vitro inhibitory potencies with IC50 around 30 nM (compounds 24 and 25). Modulation of the side chain by replacement of the terminal phenyl ring by the dicyclopropyl moiety afforded derivatives 30 and 32 with improved potencies (IC50 between 10 and 20 nM). Furthermore, replacing the linear 4-phenylbutanoyl side chain by the (2-phenylcyclopropyl)carbonyl entity provided potent inhibitors with IC50 culminating at 0.9 nM on a rat cortex enzymatic preparation (compound 70). The configuration of the cyclopropyl ring had to be R,R in order to obtain not only a strong PEP inhibition in vitro but also a good activity in vivo, exemplified by inhibitor 68, which gave ID50 ip and po of 0.3 and 1 mg/kg, respectively. Finally, demonstration of the cognition-enhancing properties of compound 54 was given in the passive avoidance test using scopolamine-induced amnesia in the rat, where it dose dependently inhibited the scopolamine-induced decrease in avoidance response.

Measles epidemic in the urban community of Niamey: transmission patterns, vaccine efficacy and immunization strategies, Niger, 1990 to 1991.

From October 1, 1990, until April 28, 1991, 13,578 cases of measles were reported in the urban community of Niamey, Niger. Vaccine coverages (one dose of Schwarz vaccine given after 9 months) in urban community of Niamey were, respectively, 63% at the age of 12 months and 73% at 24 months before the epidemic. Incidence rates were the highest among children ages 6 to 8 months and 9 to 11 months and 22% of the cases were less than 1 year old. Vaccine efficacy estimates ranged from 86 to 94% according to age groups and the method used (screening method, case control study, retrospective cohort study). The risk of transmission of illness increased with the intensity of contact with a case. Contact with a health facility 7 to 22 days before onset of rash was not a risk factor. Seasonal migrants in Niamey were more likely to develop measles. Recommendations included implementation of an early two dose schedule of measles immunization during the outbreak, vaccination offered at each contact with a health facility, radio and television advertising for measles immunization and distribution of vitamin A to all measles cases.
