Assessment of trace element contamination and effects on Paracentrotus lividus using several approaches: Pollution indices, accumulation factors and biochemical tools.

Among the most common contaminants in marine ecosystems, trace elements are recognized as serious pollutants. In Corsica (NW Mediterranean Sea), near the old asbestos mine at Canari, trace elements from the leaching of mine residues have been discharged into the sea for several decades. The aim of this study was to assess the levels of contamination in this area and the potential effects on Paracentrotus lividus (Lamarck, 1816) using pollution indices, accumulation factors and biochemical tools. For this purpose, the concentration of 24 trace elements was measured in sea urchins (gonads and gut content), macroalgae, seawater column and sediment collected at 12 stations nearby the old asbestos mine and at a reference site. The bioaccumulation of trace elements occurs as follows: macroalgae > gut > gonads. TEPI contribute to highlight contamination gradients which are mainly due to the dominant marine currents allowing the migration of mining waste along the coastline. This hypothesis was supported by TESVI, which identified characteristic trace elements in the southern area of the mine. High hydrogen peroxide content, associated with elevated catalase and glutathione-S-transferase enzyme activities, were also identified at these sites and at the reference site. Trace elements contamination as well as several abiotic factors could explain these results (e.g. microbiological contamination, hydrodynamic events, etc.). The results obtained in this study suggest that oxidative stress induced by contamination does not affect the health of Paracentrotus lividus. This work has provided a useful dataset allowing better use of sea urchins and various tools for assessing trace element contamination in coastal ecosystems.

Stress response to trace elements mixture of different embryo-larval stages of Paracentrotus lividus.

This study investigated for the first time the oxidative biomarkers responses in all larval stages of sea urchin. The contamination effects were reproduced by using contaminated seawater to concentrations measured in the area adjacent to an old asbestos mine at factors of 5 and 10. The results suggested that the concentrations were not sufficiently high to induce a major oxidative stress. The biometric differences make this method a more sensitive approach for assessing the effects on sea urchin larvae. Measurements of specific activities of antioxidant enzymes at each stage suggested a high capacity of the larvae to respond to oxidative stress. This normal activity of the organism must be considered in future research. This work also highlighted the importance of spawners provenance in ecotoxicological studies. These data are essential to better understand the stress responses of sea urchin larvae and provide baseline information for later environmental assessment research.

[Normal childbirth: physiologic labor support and medical procedures. Guidelines of the French National Authority for Health (HAS) with the collaboration of the French College of Gynaecologists and Obstetricians (CNGOF) and the French College of Midwives (CNSF) -- Text of the Guidelines (short text)]. / Accouchement normal : accompagnement de la physiologie et interventions médicales. Recommandations de la Haute Autorité de Santé (HAS) avec la collaboration du Collège National des Gynécologues Obstétriciens Français (CNGOF) et du Collège National des Sages-Femmes de France (CNSF) ­ Texte des recommandations (texte court).

OBJECTIVE: The objective of these guidelines is to define for women at low obstetric risk modalities that respect the physiology of delivery and guarantee the quality and safety of maternal and newborn care. METHODS: These guidelines were made by a consensus of experts based on an analysis of the scientific literature and the French and international recommendations available on the subject. RESULTS: It is recommended to conduct a complete initial examination of the woman in labor at admission (consensus agreement). The labor will be monitored using a partogram that is a useful traceability tool (consensus agreement). A transvaginal examination may be offered every two to four hours during the first stage of labor and every hour during the second stage of labor or before if the patient requests it, or in case of a warning sign. It is recommended that if anesthesia is required, epidural or spinal anesthesia should be used to prevent bronchial inhalation (grade A). The consumption of clear fluids is permitted throughout labor in patients with a low risk of general anesthesia (grade B). It is recommended to carry out a "low dose" epidural analgesia that respects the experience of delivery (grade A). It is recommended to maintain the epidural analgesia through a woman's self-administration pump (grade A). It is recommended to give the woman the choice of continuous (by cardiotocography) or discontinuous (by cardiotocography or intermittent auscultation) monitoring if the conditions of maternity organization and the permanent availability of staff allow it and, after having informed the woman of the benefits and risks of each technique (consensus agreement). In the active phase of the first stage of labor, the dilation rate is considered abnormal if it is less than 1cm/4h between 5 and 7cm or less than 1cm/2h above 7cm (level of Evidence 2). It is then recommended to propose an amniotomy if the membranes are intact or an oxytocin administration if the membranes are already ruptured, and the uterine contractions considered insufficient (consensus agreement). It is recommended not to start expulsive efforts as soon as complete dilation is identified, but to let the presentation of the fetus drop (grade A). It is recommended to inform the gynecologist-obstetrician in case of nonprogression of the fetus after two hours of complete dilation with sufficient uterine dynamics (consensus agreement). It is recommended not to use abdominal expression (grade B). It is recommended to carry out preventive administration of oxytocin at 5 or 10 IU to prevent PPH after vaginal delivery (grade A). In the case of placental retention, it is recommended to perform a manual removal of the placenta (grade A). In the absence of bleeding, it should be performed 30minutes but not more than 60minutes after delivery (consensus agreement). It is recommended to assess at birth the breathing or screaming, and tone of the newborn to quickly determine if resuscitation is required (consensus agreement). If the parameters are satisfactory (breathing present, screaming frankly, and normal tonicity), it is recommended to propose to the mother that she immediately place the newborn skin-to-skin with her mother if she wishes, with a monitoring protocol (grade B). Delayed cord clamping is recommended beyond the first 30seconds in neonates, not requiring resuscitation (grade C). It is recommended that the first oral dose (2mg) of vitamin K (consensus agreement) be given systematically within two hours of birth. CONCLUSION: These guidelines allow women at low obstetric risk to benefit from a better quality of care and optimal safety conditions while respecting the physiology of delivery.

INTRODUCTION: These guidelines deal with the parturient wellbeing in terms of hydration and regional and systemic pain management during labour. METHOD: Guidelines were established based on literature analysis and experts consensus. RESULTS: Clear liquids consumption is permitted all along labor and postpartum, without volume limitation, in patients at low risk of general anesthesia (grade B). The consumption of solid foods is not recommended during the active stage of labor (consensus agreement). It is recommended to promote on regional analgesia to prevent inhalation (grade A). Pain relief using regional analgesia is a part of normal childbirth. It is recommended to provide regional analgesia to parturient who wish these technics. Regional analgesia is the safest and most effective analgesic method for the mother (grade A) and the child (grade B). It is recommended to inform women on the analgesic technics, to respect their choice and consider the right for a parturient to change her strategy in obstetrical circumstances or in cases of untractable pain (consensus agreement). It is recommended to perform a "low-dose" regional analgesia that respects the experience of childbirth (grade A) and maintain it with a patient controlled epidural analgesia technics (grade A). There is no minimum cervical dilation to allow epidural analgesia (grade A). In cases of rapid labor or after delivery for revision, spinal or combined spinal epidural can be used (grade C). Epidural has not to be ended before birth (consensus agreement). Blood pressure and fetal heart rate must be monitored every 3minutes after induction and/or each 10mL bolus then hourly (consensus agreement). Systematic and preventive fluid loading is not needed if only due to regional analgesia (grade B). Deambulation or postures are allowed in the absence of motor block and must be traced and do not alter the distribution of the regional analgesia (grade C). The postures of childbirth do not alter regional analgesia spread (NP2). There is no effect low dose regional analgesia on the duration of obstetric labor, nor the rate of instrumental births or caesarean section (NP1). Systematic use of oxytocin due to epidural analgesia is neither useful nor recommended (AE). Regional analgesia has no side effect on the fetus or newborn (NP1). If regional analgesia is contraindicated or during the waiting time, alternatives analgesic drugs (entonox, nalbuphine and tramadol or pudendal block) can be used but their analgesic efficiency remains mediocre to moderate and they are associated with adverse maternal and especially neonatal side effects (NP2). Remifentanil, ketamine and volatile anesthetics are excluded from these recommendations. CONCLUSION: The present guidelines were established to update wellbeing of normal parturient during normal labor: hydration is recommended and low dose patient-controlled regional (epidural and spinal) analgesia is the most effective and safest analgesic method.

Cortical abnormalities in bipolar disorder: an MRI analysis of 6503 individuals from the ENIGMA Bipolar Disorder Working Group.

Despite decades of research, the pathophysiology of bipolar disorder (BD) is still not well understood. Structural brain differences have been associated with BD, but results from neuroimaging studies have been inconsistent. To address this, we performed the largest study to date of cortical gray matter thickness and surface area measures from brain magnetic resonance imaging scans of 6503 individuals including 1837 unrelated adults with BD and 2582 unrelated healthy controls for group differences while also examining the effects of commonly prescribed medications, age of illness onset, history of psychosis, mood state, age and sex differences on cortical regions. In BD, cortical gray matter was thinner in frontal, temporal and parietal regions of both brain hemispheres. BD had the strongest effects on left pars opercularis (Cohen's d=-0.293; P=1.71 × 10-21), left fusiform gyrus (d=-0.288; P=8.25 × 10-21) and left rostral middle frontal cortex (d=-0.276; P=2.99 × 10-19). Longer duration of illness (after accounting for age at the time of scanning) was associated with reduced cortical thickness in frontal, medial parietal and occipital regions. We found that several commonly prescribed medications, including lithium, antiepileptic and antipsychotic treatment showed significant associations with cortical thickness and surface area, even after accounting for patients who received multiple medications. We found evidence of reduced cortical surface area associated with a history of psychosis but no associations with mood state at the time of scanning. Our analysis revealed previously undetected associations and provides an extensive analysis of potential confounding variables in neuroimaging studies of BD.

Hemoperitoneum in peripartum: A case-series.

Hemorrhages are the first cause of perinatal deaths in French women. Thirteen percent of these deaths are not linked to obstetrical problems but rather to hemoperitoneum. These incidents are under-diagnosed and as a result, treatment is delayed and fetal and maternal mortality increases. We report three cases of patients, all White female in their last trimester of a non-problematic pregnancy presenting with hemoperitoneum and resulting in different outcomes. The analysis of published materials and of our cases leads us to infer that a diagnosis of hemoperitoneum must be considered in pregnant women when abdominal pain, symptoms of shock and a decrease in hemoglobin are associated. An immediate response and intensive care followed by hemostatic surgery give these patients the best chance to survive.

External rotation of the femoral component increases asymmetry of the posterior condyles.

AIMS: The morphometry of the distal femur was largely studied to improve bone-implant fit in total knee arthroplasty (TKA), but little is known about the asymmetry of the posterior condyles. This study aimed to investigate the dimensions of the posterior condyles and the influence of externally rotating the femoral component on potential prosthetic overhang or under-coverage. PATIENTS AND METHODS: We analysed the shape of 110 arthritic knees at the time of primary TKA using pre-operative CT scans. The height and width of each condyle were measured at the posterior femoral cut in neutral position, and in 3º and 5º of external rotation, using both central and medial referencing systems. We compared the morphological characteristics with those of 14 TKA models. RESULTS: In the neutral position, the dimensions of the condyles were nearly equal. Externally rotating the femoral cut by 3º and 5º with 'central referencing' induced width asymmetry > 3 mm in 23 (21%) and 33 (30%) knees respectively, while with 'medial referencing' it induced width asymmetry > 3 mm in 43 (39%) and 75 (68%) knees respectively. The asymmetries induced by rotations were not associated with gender, aetiology or varus-valgus alignment. CONCLUSION: External rotation may amplify the asymmetry between the medial and lateral condyles, and exacerbate prosthetic overhang, particularly in the superolateral zone. 'Central referencing' guides result in less potential prosthetic overhang than 'medial referencing' guides. Cite this article: Bone Joint J 2017;99-B:894-903.

IVIVC approach based on carbamazepine bioequivalence studies combination.

The aim of the present study was to explore the feasibility of obtaining an IVIVC by combination of data from two bioequivalence (BE) studies of carbamazepine (CBZ) in order to assess if the previously published dissolution media and conditions could be applicable to any other oral immediate release (IR) CBZ products with conventional excipients. Twenty-four healthy male subjects from two BE study received one IR dose of the test (test 1 or 2) or the reference formulation (Tegretol, 400 mg). Dissolution studies of the IR CBZ tablets were performed in two different laboratories. In order to develop IVIVC, individual or average data analysis were considered. A level C, level B and level A correlation have been successfully developed by combining data from different BE studies of CBZ immediate release drug products. A level A IVIVC was developed with all four datasets with a good R2 for all the combinations of in vivo and in vitro data. A dissolution medium containing 1% SLS has demonstrated its suitability as the universal biopredictive dissolution medium, even if different batches and in vivo/in vitro studies were combined.

Impact of a learning curve on the survivorship of 4802 cementless total hip arthroplasties.

AIMS: Our aim was to report survivorship data and lessons learned with the Corail/Pinnacle cementless total hip arthroplasty (THA) system. PATIENTS AND METHODS: Between August 2005 and March 2015, a total of 4802 primary cementless Corail/Pinnacle THAs were performed in 4309 patients. In March 2016, we reviewed these hips from a prospectively maintained database. RESULTS: A total of 80 hips (1.67%) have been revised which is equivalent to a cumulative risk of revision of 2.5% at ten years. The rate of revision was not significantly higher in patients aged ≥ 70 years (p = 0.93). The leading indications for revision were instability (n = 22, 0.46%), infection (n = 20, 0.42%), aseptic femoral loosening (n = 15, 0.31%) and femoral fracture (n = 6, 0.12%). There were changes in the surgical technique with respect to the Corail femoral component during the ten-year period involving a change to collared components and a trend towards larger size. These resulted in a decrease in the rate of iatrogenic femoral fracture and a decrease in the rate of aseptic loosening. CONCLUSION: The rate of revision in this series is comparable with the best performing THAs in registry data. Most revisions were not directly related to the implants. Despite extensive previous experience with cemented femoral components, the senior author noted a learning curve requiring increased focus on primary stability. The number of revisions related to the femoral component is reducing. Any new technology has a learning curve that may be independent of surgical experience.

Morphometric analysis of the distal femur in total knee arthroplasty and native knees.

AIMS: Analysis of the morphology of the distal femur, and by extension of the femoral components in total knee arthroplasty (TKA), has largely been related to the aspect ratio, which represents the width of the femur. Little is known about variations in trapezoidicity (i.e. whether the femur is more rectangular or more trapezoidal). This study aimed to quantify additional morphological characteristics of the distal femur and identify anatomical features associated with higher risks of over- or under-sizing of components in TKA. METHODS: We analysed the shape of 114 arthritic knees at the time of primary TKA using the pre-operative CT scans. The aspect ratio and trapezoidicity ratio were quantified, and the post-operative prosthetic overhang was calculated. We compared the morphological characteristics with those of 12 TKA models. RESULTS: There was significant variation in both the aspect ratio and trapezoidicity ratio between individuals. Femoral trapezoidicity was mostly due to an inward curve of the medial cortex. Overhang was correlated with the aspect ratio (with a greater chance of overhang in narrow femurs), trapezoidicity ratio (with a greater chance in trapezoidal femurs), and the tibio-femoral angle (with a greater chance in valgus knees). DISCUSSION: This study shows that rectangular/trapezoidal variability of the distal femur cannot be ignored. Most of the femoral components which were tested appeared to be excessively rectangular when compared with the bony contours of the distal femur. These findings suggest that the design of TKA should be more concerned with matching the trapezoidal/rectangular shape of the native femur. TAKE HOME MESSAGE: The distal femur is considerably more trapezoidal than most femoral components, and therefore, care must be taken to avoid anterior prosthetic overhang in TKA

Extensor tendon ruptures after total knee arthroplasty.

Extensor tendon rupture is a rare but serious complication after total knee arthroplasty (TKA) that impairs active knee extension, thereby severely affecting knee function. Surgery is usually required. Surgical options range from simple suturing to allograft reconstruction of the entire extensor mechanism and include intermediate methods such as reconstruction using neighbouring tendons or muscles, synthetic ligament implantation, and partial allograft repair. Simple suturing carries a high failure rate and should therefore be routinely combined with tissue augmentation using a neighbouring tendon or a synthetic ligament. After allograft reconstruction, outcomes are variable and long-term complications common. Salvage procedures for managing the most severe cases after allograft failure involve reconstruction using gastrocnemius or vastus flaps. Regardless of the technique used, suturing must be performed under tension, with the knee fully extended, and rehabilitation must be conducted with great caution. Weaknesses of available case-series studies include small sample sizes, heterogeneity, and inadequate follow-up duration. All treatment options are associated with substantial failure rates. The patient should be informed of this fact and plans made for a salvage option. Here, the main techniques and their outcomes are discussed, and a therapeutic strategy is suggested.

Increased incidence of femoral fractures in small femurs and women undergoing uncemented total hip arthroplasty - why?

The aim of this study was to investigate the relationship between the geometry of the proximal femur and the incidence of intra-operative fracture during uncemented total hip arthroplasty (THA). We studied the pre-operative CT scans of 100 patients undergoing THA with an uncemented femoral component. We measured the anteroposterior and mediolateral dimensions at the level of division of the femoral neck to calculate the aspect ratio of the femur. Wide variations in the shape of the femur were observed, from round, to very narrow elliptic. The femurs of women were narrower than those of men (p < 0.0001) and small femurs were also narrower than large ones. Patients with an intra-operative fracture of the calcar had smaller and narrower femurs than those without a fracture (p < 0.05) and the implanted Corail stems were smaller in those with a fracture (mean size 9 vs 12, p < 0.0001). The variability of the shape of the femoral neck at the level of division contributes to the understanding of the causation of intra-operative fractures in uncemented THA.

[Anticoagulation and peripartum management]. / Influence des anticoagulants sur la prise en charge péri-partum.

OBJECTIVE: To compare peripartum management of anticoagulated patients concerning locoregional analgesia, post-partum hemorrhage and thrombotic events according to planified interruption or not of antithrombotic therapy. PATIENTS AND METHODS: We conducted a single tertiary care center retrospective study of all deliveries associated with antithrombotic therapy from January 2005 to September 2011. RESULTS: We identified 120 cases with prophylactic (71%) or curative (29%) anticoagulation. Two thrombotic events occurred. In case of curative therapy, the use of locoregional analgesia was lower (P<0.0001) and post-partum hemorrhage occurred more frequently (P=0.07) compared to prophylactic therapy. According to planified interruption or not of antithrombotic therapy, we observed a more prolonged duration of therapeutic interruption before delivery (55.6h±63.3 vs 26.4 h±11.6, P<0.0001), higher use of locoregional analgesia (83% vs 71%, P=0.02) but no difference concerning cesarean rate (35% vs 39%, P=0.8) or post-partum hemorrhage (13% vs 14%, P=0.9). CONCLUSION: In case of curative anticoagulation, plannified interruption favours the use of perimedullar analgesia after 24hour delay. In case of preventive anticoagulation, plannified interruption appears unnecessary as the 12hour delay is easier to reach.

[Antenatal management for patients with increased risk of post-partum hemorrhage (excluding abnormal placentation)]. / Prise en charge anténatale des patientes à risque d'hémorragie du post-partum (hors anomalies de l'insertion placentaire).

OBJECTIVES: To describe management and screening for high-risk patients concerning post-partum hemorrhage (PPH) and antenatal management for severe anemia, thrombopenia, bleeding disorders and anticoagulant therapy. METHODS: Bibliographic search restricted to French and English languages using Medline database and recommendations of medical societies. RESULTS: The appropriate place for delivery should be chosen after multidisciplinary concertation based on level of risk (especially past-history of severe PPH and bleeding disorder) and easy access to blood products (Professional Consensus). Prevention for severe anemia is mainly based on oral iron supplementation (grade B). Explorations are required in case of thrombopenia<100Giga/L (grade C). Patients with bleeding disorder require the assistance of a physician skilled in hemostasis for perinatal management (grade C). Preventive anticoagulant therapy has no impact on PPH risk and perimedullar analgesia is usually authorized 12hours after last injection (grade C). Curative anticoagulant therapy slightly increases PPH risk and perimedullar analgesia is authorized only after 24hours since last injection (Professional Consensus). CONCLUSION: Prenatal identification of high-risk patients concerning PPH implies multidisciplinary concertation to determine the most appropriate birthplace where technical and human resources are available.

Epidural injection of hydroxyethyl starch in the management of postdural puncture headache.

Epidural blood patch is the standard treatment for postdural puncture headache when symptomatic therapy is ineffective. We report the cases of two patients who received an epidural injection of hydroxyethyl starch when an epidural blood patch was contraindicated; one due to Streptococcus agalactiae bacteraemia and one due to acute leukaemia. Relief of headache was achieved in both patients with no adverse effects. The use of an epidural hydroxyethyl starch injection may be a suitable alternative for treatment of postdural puncture headache if epidural blood patch is contraindicated.

[Analysis of fetal heart rate abnormalities occurring within one hour after laying of epidural analgesia]. / Analyse des anomalies du rythme cardiaque fœtal survenant dans l'heure suivant la pose d'une analgésie péridurale.

OBJECTIVES: The objective of this study is to classify abnormalities of fetal heart rate (FHR) occurring in the first hour after performing the epidural analgesia, and to assess the impact of these abnormalities on delivery and on after-birth neonatal state. PATIENTS AND METHODS: Retrospective study of 6676 patients continuously from 1 January 2007 to 31 December 2010 who benefited, during the labor, of epidural analgesia. Seven hundred and sixty (14,1%) presented anomalies of FHR in the hour following the laying of epidural (group 1), and 5916 showed no abnormalities of the RCF (group 2). RESULTS: Among the 760 anomalies of the FHR in the hour following the laying of epidural, 319 (42%) showed prolonged decelerations, 169 (22.2%) variable decelerations, 122 (16.1%) early decelerations, 110 (14.5%) late decelerations and 40 bradycardia (5.3%). In the group 1, incidence of caesarean delivery was 21.4% (163 patients); in group 2, it was 9.63% (P<0.002). In group 1, the umbilical artery pH was less than 7.20 in 13,6% of patients, whereas in group 2, the prevalence was only 6,5% (P<0.002). There is no statistically significant differences on Apgar score between the two groups. CONCLUSION: This study helped to characterize anomalies in the FHR following epidural. There is an increase of obstetric interventions. There is no impact on neonatal clinical state. The administration of systematic ephedrine shall be investigated to reduce these interventions.

[Antimicrobial prophylaxis for caesarean delivery: changes in practice and administration before incision, feasibility study to paediatricians in Auvergne]. / Antibioprophylaxie pour césarienne: modification des pratiques et administration avant incision, enquête de faisabilité auprès des pédiatres du réseau de santé périnatale d'Auvergne (RSPA).

OBJECTIVE: To describe the knowledge of paediatricians regarding the practice of antimicrobial prophylaxis for caesarean section in reference to the Consensus Conference of the French Society of Anesthesia and Intensive Care (SFAR) and assess the feasibility of a change in attitude (injection of the antibiotic prior to incision) among paediatricians Perinatal Health Network of Auvergne (RSPA) working in maternity. STUDY DESIGN: Cross sectional study by survey. METHODS: First questionnaire was sent to 46 RSPA paediatricians working in maternity. Almost one-third of paediatricians who returned the questionnaire said they were not concerned. A second questionnaire was developed with two paediatricians of the CHU and sent to the same 46 paediatricians. The statistical part involved percentages. RESULTS: Response rates were respectively 61% and 67%. For the first questionnaire, only 25% of the paediatricians knew the antibiotic and the time for injection. For the second questionnaire, 87% were in favour of an administration before incision and 42% thought it will not affect the care of the newborn. For 35% of respondents, it could lead to a change in the duration of antibiotic therapy in cases of perinatal infection and for 13% only a delay in the implementation of antibiotic therapy in children. CONCLUSION: The RSPA paediatricians did not know the practices of antibiotic prophylaxis for caesarean section. However, they did not appear opposed to an administration before cord clamping as it would not delay the implementation of any antibiotics in the newborn.

Techniques and pitfalls with the Salto prosthesis: our experience of the first 15 years.

The Salto total ankle replacement system has shown to be a viable alternative in the treatment of symptomatic arthritis. However, although outcomes after total ankle replacement are promising, an exact analysis of surgical technique could help to improve them. Based on a 15 years experience with the Salto Total Ankle replacement system, the uthors discuss the surgical technique and its pitfalls, its inications and limitations in current practice.

Management of HSV-1 encephalitis due to reactivation of HSV-1 during late pregnancy.

A previously healthy 31-year-old G4P2 woman at 33 weeks of gestation was admitted as an emergency with a pyrexia of 39°C, vomiting, headache and neck stiffness associated with photophobia, phonophobia and visual and auditory symptoms. There were no heraldic signs of eclampsia. Polymerase chain reaction and testing for herpes simplex virus in the cerebrospinal fluid diagnosed herpes simplex-1 meningoencephalitis. Following acyclovir, the clinical course improved. Spontaneous vaginal delivery occurred at 39 weeks of gestation with epidural analgesia using ropivacaine. Mother and child were neurologically normal and healthy 15 months later. Early administration of acyclovir is essential to reduce the risk of neurological complications. After treatment and a negative polymerase chain reaction for herpes simplex virus in the cerebrospinal fluid, epidural analgesia with local anesthetic and sufentanil is possible.
