Amniocentesis learning: Use of a home-made simulator.

BACKGROUND: Amniocentesis is the most performed invasive prenatal diagnostic procedure. Learning the procedure is difficult for the learner, the teacher and the patient because of the risks inherent to this technique and the anxiety generated by the procedure. The objective of this work was to evaluate a theoretical and practical amniocentesis training workshop using a simulator. METHODS: We were inspired by Pierre Jean's precepts for the planning of a medical training. We then carried out the pedagogical session with the gynecology residents of our Regional University Hospital, a type 3 maternity hospital in France. We evaluated the theoretical learning through a questionnaire before and after the training and then the practical session on a home-made simulator. The satisfaction of the participants was assessed by a questionnaire at the end of the session. RESULTS: Fifteen learners, from the first to the last semester of internship, participated in the training. The median score of the pre-training questionnaire ("pre-test" questionnaire) was 3.3 out of 10 (min = 1, max = 6) and that of the post-training questionnaire ("post-test" questionnaire) was 7.9 out of 10 (min = 6, max = 9). The post-training scores were significantly higher (p < 0.0007). The average score for the practical training was 30.5 out of 40 (24-36). 93 % of the learners were fully satisfied with the theoretical training and 100 % stated that they had improved their technical skills. CONCLUSION: The residents in our department expressed a need for training in this invasive procedure of antenatal diagnosis. The training proved to be beneficial following the evaluation of the learning but also following the feedback of the learners.

[Impact of a service protocol on the practice of vaginal delivery of breech presentations at term]. / Impact d'un protocole de service sur la pratique de l'accouchement voie basse des présentations du siège à terme.

OBJECTIVES: The delivery of breech presentations remains controversial. Our study analysed the impact of a service protocol on the proportion of planned vaginal delivery and its success. Immediate neonatal morbidity and factors that may influence the success of vaginal delivery were studied. METHODS: Retrospective study, between 2009 and 2020 at the CHRU of Limoges, type 3 maternity hospital, on patients with a breech foetus at term. The proportion of planned vaginal delivery and the rate of effective vaginal delivery were compared before/after 2015. Neonatal morbidity was compared for planned vaginal delivery and planned cesarean delivery groups. RESULTS: We included 923 patients. The rate of planned vaginal delivery was significantly higher after 2015 from 5.2% to 19% (P<0.001), with a success rate increasing from 60% to 82.1% (P=0.06). The rate of vaginal breech deliveries significantly increased from 3.8% to 17% (P<0.001). We found significantly more newborns with moderate acidosis when a vaginal delivery was attempted (P<0.001). The success of vaginal delivery was correlated to the Magnin index (P=0.044), to gestational age (P=0.037), and to multiparity (OR 3.78 95% CI [1.42-10.03] P=0.006). CONCLUSION: Our study demonstrates the benefits of setting up a service protocol for the practice of breech vaginal delivery.

[External validation of FullPIERS model for prediction of adverse outcomes among women with pre-eclampsia in French maternity of 2014 to 2018]. / Validation externe du modele FullPIERS dans la pré-éclampsie à partir d'une série française de 4 ans.

OBJECTIVES: FullPIERS score (Pre-eclampsia Integrated Estimate of RiSk) is built in order to predict maternal outcomes among women with preeclampsia. Our objective is to assess external validity of this score among a population of French women. METHODS: A retrospective study was conducted for all patients with pre-eclampsia (severe or not) admitted to a tertiary hospital center. A receiver operating characteristic (ROC) curve was constructed to determine accuracy of the model at 48 hours and 7 days after admittance and area under the curve (AUC) was calculated. RESULTS: In total, 276 patients meet inclusions criterion. Among them, 217 were included and 61 (28 %) had one or more complication. Only 8 patients had two complications at two different moments (one at 48 hours and one at 7 days). The FullPiers score predicted maternels events at 48 hours with an area under the curve at 0.80 (IC95 % [0.74-0.85]). At 4.2 cut off, the sensitivity was 71 % and specifity 88 %. At 7 days, the area under the curve was 0.74 (IC95 % [0.67-0.79]), admiting a cutoff point for FullPIERS probability of 3.4, sensitivity was 59 % and specificity 85 %. CONCLUSIONS: Our study show utility of FullPIERS score in french maternity. This model might be a useful tool for predicting complications in women with pre-eclampsia. Using of this score in clinical practice might help improving optimization of patient's care.

Is there an interest in repeating the vaginal administration of dinoprostone (Propess®), to promote induction of labor of pregnant women at term? (RE-DINO): study protocol for a randomized controlled trial.

BACKGROUND: Labor is induced in over 20% of women in France. Prostaglandins, especially intravaginal dinoprostone (Propess®), are widely used to initiate cervical ripening. If labor does not start within 24 h, there is uncertainty about whether to administer a second dinoprostone pessary or to use oxytocin to induce labor in order to achieve a vaginal delivery. METHODS: RE-DINO is a prospective, open-label, multicenter, randomized superiority trial with two parallel arms running in six French hospitals. A total of 360 patients ≥ 18 years of age at > 37 weeks of gestation who exhibit unfavorable cervical conditions (Bishop score < 6) 24 h after placement of the first Propess®, with fetuses in cephalic presentation, will be included. Patients with premature membrane rupture, uterine scars, or multiple pregnancies will be excluded. Our principal objective is to determine whether placement of a second Propess® (followed by oxytocin [Syntocinon®], if necessary) in women for whom the first Propess® failed to induce cervical ripening increases the vaginal delivery rate compared to direct oxytocin injection. The vaginal delivery rate is therefore the primary outcome. The secondary outcomes are the induction failure rates and maternofetal morbidity and mortality. DISCUSSION: This study may help in determining the optimal way to induce labor after failure of a first Propess®, an unresolved problem to date. This trial explores the effectiveness and safety of placing a second Propess® and may contribute to development of an obstetric consensus. TRIAL REGISTRATION: Registered on 2 September 2016 at clinicaltrials.gov (identification number NCT02888041).

Fetal supraventricular tachycardia and cystic fibrosis: Coincidence or association? Two case reports.

Prenatal diagnosis of cystic fibrosis (CF) is difficult and is mainly considered upon identification of digestive sonographic signs. Although such an association has never been described until now to our knowledge, we report two cases of fetal arrhythmia associated with cystic fibrosis. This association may be explained by the physiopathology of heart in the context of CF, but nevertheless needs to be confirmed by other reports. The prenatal diagnosis of CF is important in order to implement early appropriate care, with better prognosis. The finding of possibly new associated prenatal signs may then improve the global management of the disease.

[Cervical ripening after previous cesarean section with dinoprostone vaginal insert]. / Déclenchement par dinoprostone et utérus cicatriciel.

OBJECTIVES: Because, to date in France, 20 % of pregnant women had a scared uterus and because the best mean of cervical ripening is unknown and controversial, we want to evaluate efficacy and safety of dinoprostone for cervical ripening in women with previous cesarean. MATERIALS AND METHODS: We conducted a retrospective unicentric study, from 2010 to 2014, at Limoges regional university hospitals. Two hundred and sixty nine patients, with medical indication for induction of labor and scared uterus, were included and ripened with dinoprostone (Propess® and/or Prostine®). Women had unfavorable cervix with Bishop score inferior to 6. RESULTS: Overall rate of vaginal delivery was 62 %. Patients have had more of one prostaglandin in 19 % of cases; the cesarean rate was significantly higher in this case (cesarean: 55.6 % vs. vaginal delivery: 44.4 %; P=0.0043). Overall, there were respectively 4 % and 0.7 % of post-partum hemorrhage and uterine rupture. One percent of newborns had a severe acidosis (pH<7 in umbilical artery) and 1 % was admitted to the Intensive Neonatal Care Unit. CONCLUSION: Dinoprostone is an effective procedure in patients with previous cesarean section requiring labor induction, with a morbidity comparable to other methods of induction of labor.

Diagnosis and surgical treatment of dysplasia epiphysealis hemimelica. A report of nine cases.

BACKGROUND: Dysplasia epiphysealis hemimelica (DEH) is a rare developmental bone disorder with hemimelic involvement of one or more epiphysis. We report on nine new cases and discuss the clinical manifestations, the value of MRI, and the results of complete and early surgical resection of these lesions. MATERIALS AND METHODS: In this retrospective study, nine patients with a diagnosis of DEH were evaluated. Age at presentation ranged from 1 year to 12 years. The main complaint at diagnosis was a swelling bony mass. Angular deformities were recorded in two patients. All patients were surgically treated and followed up clinically and by imaging. Eight patients underwent excision only. RESULTS: The average follow-up was 5.6 years (range, 2-10.5 years). All patients had a good outcome without related symptoms. No epiphysiodesis, angular deformity or recurrence was observed. One patient with femoral lesion involving the distal medial part of the epiphysis developed, four months after surgical excision, a calcification outside the area of total excision. This calcification did not increase in size at two years follow-up. Another patient with lateral involvement of the proximal tibial epiphysis presented a postoperative nervous complication. Spontaneous nervous recovery occurred three months after surgery. DISCUSSION: MRI was useful to find a potential plane of cleavage between the epiphysis and the pathological tissue. We recommend early removing ossifications when a cleavage plane is identified. Waiting a possible complication or increasing of size does not seem logical. Of course, the treatment will be not the same if no cleavage plane is found on MRI. LEVEL OF EVIDENCE: IV.

[Prenatal diagnosis and evolution of patent urachus]. / Diagnostic et évolution prénatale de l'ouraque perméable: à propos d'un cas.

Prenatal ultrasonographic features of patent urachus consist in anechoic proximal cord cyst communicating with the bladder associated with large umbilicus. Distinction should be made with omphalocele and bladder extrophy. Spontaneous evolution leads to rupture during mid-trimester and bladder protrusion. Karyotyping is not mandatory in isolated typical cases. Early postnatal surgery is usually required.

Induced-membrane femur reconstruction after resection of bone malignancies: three cases of massive graft resorption in children.

Bone reconstruction after surgical resection of bone malignancies in children remains a difficult challenge. Induced-membrane reconstruction as described by Masquelet et al. was originally reported in traumatic or septic bone defects and is now adapted to this field. We report here three cases of massive femoral graft resorption requiring surgical revision in two boys aged 3 and 6 years and a 9-year-old girl. Hypotheses include the long delay between the two stages, nature of the bone graft, high varus loads specific to this location, and lack of stability of the fixation. This technique has recently provided promising preliminary results when applied to the field of bone tumours. However, reconstruction of the femur seems to be specifically associated with a risk of graft resorption. Identification of the origin of this major complication is needed to amend the technique or its indications.

[Knee arthroscopy in children]. / Arthroscopie du genou de l'enfant.

PURPOSE OF THE STUDY: Between 1990 and 1998, 110 knee arthroscopies were performed in children. We analyzed the epidemiology and diagnostic data and studied the correlation between clinical and radiographic findings and the final diagnosis after arthroscopy in order to establish a consensus on use of knee arthroscopy in children. MATERIAL AND METHODS: We made a retrospective analysis of 110 knee arthroscopies performed in children, classing the patients in three age groups: 0-5 years, 5-10 years, 10-17 years. Clinical and radiological findings were compared with the arthroscopy findings. RESULTS: One or more arthroscopies were performed in 56 boys and 48 girls. Mean age at the time of the procedure was 12 years 4 months. There were 11 children aged 0-5 years, 14 aged 5-10 years and 85 aged 10-17 years. The main pathology was arthritis in the 0-5 year and 5-10 year age groups. Trauma was more frequent in the older children. Knee arthroscopy was found to be normal in 19 cases. DISCUSSION: For most surgery teams, arthroscopy is indicated for arthritis of the knee. Arthroscopy may also be needed for hemarthrosis. In these contexts, arthroscopy is both a diagnostic and therapeutic procedure. Our analysis demonstrates that emergency arthroscopy is only warranted for free floating osteochondral fractures and fractures of the tibial articular surfaces, with the exception of the tibial spines. Arthroscopy may be performed later in other cases after careful physical examination and radiographic series. We had 19 normal arthroscopies and 10 that showed femoropatellar chondropathies and plicas that could explain knee pain. We recommend arthrography before arthroscopy to avoid unnecessary procedures. CONCLUSION: Arthritis of the knee is an excellent indication for arthroscopy. Painful and acute hemarthrosis requires attentive physical exams and x-rays before making the decision for surgery.

[Fractures of the intercondylar eminence of the tibia in children. Apropos of 25 cases with a 1-20 year follow up]. / Fractures de l'éminence intercondylaire du tibia de l'enfant. A propos de 25 cas avec un recul de 1 à 20 ans.

PURPOSE OF THE STUDY: This study tries to clarify the diagnostic strategy in intercondylar eminence fractures of the tibia and aids the deduction of therapeutic options based on the analysis of the long-term morbidity of anterior laxity. MATERIAL AND METHODS: This retrospective, monocentric study of 25 children with a mean age of 11.8 years (7-15 years) was performed with an average follow-up of 7.2 years (1-20 years). Fractures are itemized with Meyers-McKeever modified by Zaricznyj and Zifko-Gaudernak classifications. Conservative treatment (16 patients) consisted of hemarthrosis aspiration, ligament examination, manipulation into extension and cast immobilization under general anesthesia. Surgical treatment (9 patients) consisted of wire suture fixation (4 times), wire suture fixation held by a screw (3 times) and direct screw fixation (2 times). Four patients were lost to follow-up. Patients were evaluated with the Lysholm (21 patients) and IKDC (15 patients) scores systems. Anterior laxity was checked with a KT-1000 arthrometer. Antero-posterior and lateral X-rays were performed. The statistical analysis was carried out with Mann-Whitney and Fischer tests. RESULTS: There are 18 good or very good results and only 3 medium with the Lysholm score and 5 knees graded A, 9 graded B and 1 graded C with the IKDC score. Mean anterior laxity is 1.86 mm (0 to 4 mm) after conservative treatment and 1.5 mm (-1 to 4 mm) after operative treatment. 5 patients have an anterior laxity and only 2 an anterior instability. No arthritic lesions, 1 nonunion, and 11 malunions have been observed, mainly after conservative treatment. DISCUSSION: Ligament examination under general anesthesia is useless for displaced fractures and dangerous for those were not displaced. Diagnostic arthroscopy is not yet allowed. Magnetic Resonance Imaging is useful to explore osteochondral fractures and symptomatic meniscal lesions. Laxity is the consequence of anterior cruciate ligament elongation. CONCLUSION: The diagnosis of these fractures rests on a simple radio-clinical examination to determinate the exact position, the displacement and the size of the osteochondral fragment in order to choose the best treatment. Conservative treatment will be chosen preferentially because of a poor long-term morbidity. Treatment will be surgical, preferably arthroscopic, in the others cases.

Orthopaedic treatment and passive motion machine: consequences for the surgical treatment of clubfoot.

The efficacy of orthopaedic treatment and its influence on clubfoot surgery has never been truly demonstrated. In the unsorted mass of clubfeet treated, it is difficult to determine exactly how effective orthopaedic treatment is for severely affected feet. If properly performed, perfectly synchronized, and supported by a Kinetec machine, such treatment can noticeably reduce the rate of operation and, when operation is still required, reduce its extent. In grade II soft > stiff feet with scores of 5-10, Kinetec-supported orthopaedic treatment is extremely effective. Operation is required in 32% of cases only, and posterior surgery is often sufficient. Lateral release, in this category, is never required. In grade III stiff > soft feet, with scores of 10-15, the efficacy of orthopaedic treatment associated with the Kinetec machine is far from negligible and operation most often includes posterior and medial release (PMR), variably associated with plantar release. Lateral release is exceptional (15%), and operation is necessary in 75% of cases. In grade IV stiff = stiff feet, with scores of 15-20, orthopaedic treatment with the Kinetec machine has a true, though limited, effect. In this category, operation is necessary in 90% of cases. Lateral release is performed in 50%. In the postoperative period, orthopaedic treatment combined with use of the Kinetic machine must be continued. Orthopaedic treatment coordinated with use of the machine has considerably shortened the duration of plaster cast immobilization; 2 months when operation included posterolateral-medial (PLMR) release or PMR, and only 1 month when operation was posterior release (PR). The machine has noticeably changed the results and has indisputably influenced operation on the whole.

Classification of clubfoot.

Clubfeet must be classified according to severity to obtain reference points, assess the efficacy of orthopaedic treatment, and analyze the operative results objectively. A scale of 0-20 was established on the basis of four essential parameters: equinus in the sagittal plane, varus deviation in the frontal plane and derotation around the talus of the calcaneo-forefoot (CFF) block and adduction of forefoot on hindfoot in the horizontal plane. Four grades of clubfeet can be individualized: (a) Benign feet so-called "soft-soft feet," grade I, similar to postural feet, with a score of 5 to 1 (these mild feet must be excluded from any statistics as they tend to increase good results); (b) moderate feet, so-called "soft > stiff feet," grade II (reducible but partly resistant, with a score of 5-10); (c) severe feet, so-called "stiff > soft feet," grade III (resistant but partly reducible, with a score of 10-15); and (d) very severe, pseudoarthrogryposic feet, so-called "stiff-stiff feet," grade IV (score of 15-20 points). To avoid risks of errors, our method is based on a very complete checklist and on diagrams. Our training material inculdes an audiovisual package.
