[Gynecological care among women reporting sexual violence: a qualitative study]. / Recours au soin gynécologique chez les femmes rapportant des violences sexuelles : étude qualitative.

INTRODUCTION: Sexual violence can be followed by different levels of gynecological care. Our objective was to characterise gynecological care and to identify the related factors among women who had reported sexual violence. METHODS: Twenty-five semi-structured interviews were conducted among adult women who reported sexual violence during childhood or as adults. Topics addressed included gynecological health, gynecological care and experienced violence, RESULTS: Interviewed women, aged 20-60, had a good professional integration and a high level of education. The violence had often been committed by a relative or acquaintance. For the women interviewed, the least use of gynecological care was motivated by a desire to avoid the gynecological examination. Among women who had regular check-ups, the desire to conform to the norm explained their need for gynecological check-ups, which was similar to that of women who had never been subjected to violence. Lastly, some care pathways were characterised by multiple recourse of gynecological care for complaints with identical motives. The women interviewed expected professionals to spontaneously identify the violence they had suffered and the gynecological consequences attributed to such violence. CONCLUSION: Individual and interpersonal differences in levels of gynecological care use were related to the characteristics of the violence and its perceived effects on gynecological health. It would be interesting to extend this research by examining the care pathways of women with other socioeconomic characteristics. A quantitative study would measure the association between violence and the use of gynecological care.

AC compensation of 3D magnetic diagnostic signals in DIII-D and National Spherical Torus Experiment-Upgrade (NSTX-U) for real-time application.

A time domain algorithm has been developed to remove the vacuum pickup generated by both coil current (DC) and induced vessel current (AC) in real time from three dimensional (3D) magnetic diagnostic signals in the National Spherical Torus Experiment-Upgrade (NSTX-U) and DIII-D tokamaks. The possibility of detecting 3D plasma perturbations in real time is essential in modern and future tokamaks to avoid and control MHD instabilities. The presence of vacuum field pickup, due to toroidally asymmetric (3D) coils or to misalignment between sensors and axisymmetric (2D) coils, pollutes the measured plasma 3D field, making the detection of the magnetic field produced by the plasma challenging. Although the DC coupling between coils and sensors can be easily calculated and removed, the AC part is more difficult. An algorithm based on a layered low-pass filter approach for the AC compensation and its application for DIII-D and NSTX-U data is presented, showing that this method reduces the vacuum pickup to the noise level. Comparison of plasma response measurements with and without vacuum compensation shows that accurate mode locking detection and plasma response identification require precise AC and DC compensations.

Orbital symmetries of charge density wave order in YBa2Cu3O6+x.

Charge density wave (CDW) order has been shown to compete and coexist with superconductivity in underdoped cuprates. Theoretical proposals for the CDW order include an unconventional d-symmetry form factor CDW, evidence for which has emerged from measurements, including resonant soft x-ray scattering (RSXS) in YBa2Cu3O6+x (YBCO). Here, we revisit RSXS measurements of the CDW symmetry in YBCO, using a variation in the measurement geometry to provide enhanced sensitivity to orbital symmetry. We show that the (0 0.31 L) CDW peak measured at the Cu L edge is dominated by an s form factor rather than a d form factor as was reported previously. In addition, by measuring both (0.31 0 L) and (0 0.31 L) peaks, we identify a pronounced difference in the orbital symmetry of the CDW order along the a and b axes, with the CDW along the a axis exhibiting orbital order in addition to charge order.

High-fidelity vibrokinetic stimulation induces sustained changes in intercortical coherence during a cinematic experience.

OBJECTIVE: High-fidelity vibrokinetic (HFVK) technology is widely used to enhance the immersiveness of audiovisual (AV) entertainment experiences. However, despite evidence that HFVK technology does subjectively enhance AV immersion, the underlying mechanism has not been clarified. Neurophysiological studies could provide important evidence to illuminate this mechanism, thereby benefiting HFVK stimulus design, and facilitating expansion of HFVK technology. APPROACH: We conducted a between-subjects (VK, N = 11; Control, N = 9) exploratory study to measure the effect of HFVK stimulation through an HFVK seat on electroencephalographic cortical activity during an AV cinematic experience. Subjective appreciation of the experience was assessed and incorporated into statistical models exploring the effects of HFVK stimulation across cortical brain areas. We separately analyzed alpha-band (8-12 Hz) and theta-band (5-7 Hz) activities as indices of engagement and sensory processing, respectively. We also performed theta-band (5-7 Hz) coherence analyses using cortical seed areas identified from the theta activity analysis. MAIN RESULTS: The right fusiform gyrus, inferiotemporal gyrus, and supramarginal gyrus, known for emotion, AV-spatial, and vestibular processing, were identified as seeds from theta analyses. Coherence from these areas was uniformly enhanced in HFVK subjects in right motor areas, albeit predominantly in those who were appreciative. Meanwhile, compared to control subjects, HFVK subjects exhibited uniform interhemispheric decoherence with the left insula, which is important for self-processing. SIGNIFICANCE: The results collectively point to sustained decoherence between sensory and self-processing as a possible mechanism for how HFVK increases immersion, and that coordination of emotional, spatial, and vestibular processing hubs with the motor system may be required for appreciation of the HFVK-enhanced experience. Overall, this study offers the first ever demonstration that HFVK stimulation has a real and sustained effect on brain activity during a cinematic experience.

[Gastric and pancreatic cancers: Will neoadjuvant (chemo)radiotherapy replace adjuvant chemoradiotherapy?] / Cancers gastriques et pancréatiques : la (chimio)radiothérapie néoadjuvante remplacera-t-elle la chimioradiothérapie adjuvante ?

For many years, adjuvant chemoradiotherapy remained essential in the therapeutic management of gastric and pancreatic adenocarcinomas. For these tumours, surgical excision, the only hope of offering the patient prolonged survival, is only possible in 20% of cases. The median survival of operated patients is only 12 to 20 months due to the frequency of locoregional and/or metastatic recurrences. For stomach cancers, adjuvant chemoradiotherapy is justified by the results of the phase III trial Intergroup 0116 published by MacDonald et al. The gain in survival was at the cost of significant toxicity. This treatment was supplanted in the early 2000s by perioperative chemotherapy. Currently, neoadjuvant chemoradiotherapy clinical studies are ongoing with the aim of improving treatments observance and tolerance. For pancreatic cancers, the role of adjuvant chemoradiotherapy has long been discussed because of trials with contradictory results. Neoadjuvant radiotherapy has many advantages in terms of efficacy and tolerance. It increases the chances of subsequent complete tumour resection. Several prospective trials are currently ongoing to clarify its place in the therapeutic arsenal.

Compact steady-state tokamak performance dependence on magnet and core physics limits.

Compact tokamak fusion reactors using advanced high-temperature superconducting magnets for the toroidal field coils have received considerable recent attention due to the promise of more compact devices and more economical fusion energy development. Facilities with combined fusion nuclear science and Pilot Plant missions to provide both the nuclear environment needed to develop fusion materials and components while also potentially achieving sufficient fusion performance to generate modest net electrical power are considered. The performance of the tokamak fusion system is assessed using a range of core physics and toroidal field magnet performance constraints to better understand which parameters most strongly influence the achievable fusion performance. This article is part of a discussion meeting issue 'Fusion energy using tokamaks: can development be accelerated?'.

Short-Term Efficacy and Safety of Torasemide and Furosemide in 366 Dogs with Degenerative Mitral Valve Disease: The TEST Study.

BACKGROUND: Furosemide is the only loop diuretic recommended by the ACVIM consensus guidelines for treatment of congestive heart failure (CHF) in dogs related to degenerative mitral valve disease (DMVD). Torasemide is another potent loop diuretic with a longer half-life and a higher bioavailability. OBJECTIVES: (1) To demonstrate that torasemide given once a day (q24h) is noninferior to furosemide given twice a day (q12h) for treating dogs with CHF; (2) and to compare the effect of the 2 drugs on the time to reach a composite cardiac endpoint "spontaneous cardiac death, euthanasia due to heart failure or CHF class worsening." ANIMALS: A total of 366 dogs with CHF attributable to DMVD. METHODS: Analysis of 2 prospective randomized single-blinded reference-controlled trials was performed. Dogs orally received either torasemide q24h (n = 180) or furosemide q12h (n = 186) in addition to standard CHF therapy over 3 months. The primary efficacy criterion was the percentage of dogs with treatment success assessed in each study. The time to reach the composite cardiac endpoint was used as secondary criterion in the overall population. RESULTS: Torasemide was noninferior to furosemide (Ptorasemide  - Pfurosemide  = +7%; 95% CI [-8%; +22%] and Ptorasemide  - Pfurosemide  = +1%; 95% CI [-12%; +14%], respectively, in Study 1 and Study 2). Torasemide (median dose = 0.24 mg/kg/d q24h; range = 0.10-0.69 mg/kg/d) was associated with a 2-fold reduction in the risk of reaching the composite cardiac endpoint (adjusted HR = 0.47; 95% CI = 0.27-0.82; P = 0.0077) as compared with furosemide (median dose = 1.39 mg/kg q12h; range = 0.70-6.30 mg/kg q12h). CONCLUSIONS AND CLINICAL IMPORTANCE: Torasemide q24h is an effective oral diuretic in dogs with CHF.

Higher-order mode suppression in twisted single-ring hollow-core photonic crystal fibers.

A hollow-core single-ring photonic crystal fiber (SR-PCF) consists of a ring of capillaries arranged around a central hollow core. Spinning the preform during drawing introduces a continuous helical twist, offering a novel means of controlling the modal properties of hollow-core SR-PCF. For example, twisting geometrically increases the effective axial propagation constant of the LP01-like modes of the capillaries, providing a means of optimizing the suppression of HOMs, which occurs when the LP11-like core mode phase-matches to the LP01-like modes of the surrounding capillaries. (In a straight fiber, optimum suppression occurs for a capillary-to-core diameter ratio d/D=0.682.) Twisting also introduces circular birefringence (to be studied in a future Letter) and has a remarkable effect on the transverse intensity profiles of the higher-order core modes, forcing the two-lobed LP11-like mode in the untwisted fiber to become three-fold symmetric in the twisted case. These phenomena are explored by means of extensive numerical modeling, an analytical model, and a series of experiments. Prism-assisted side-coupling is used to measure the losses, refractive indices, and near-field patterns of individual fiber modes in both the straight and twisted cases.

[Prevalence of carotid artery stenosis in nonagenarians: Survey in a primary care hospital]. / Prévalence d'une sténose carotidienne chez le nonagénaire : résultats d'une enquête hospitalière.

AIM: Carotid artery stenosis increases with age and may cause brain ischemia if arterial hypotension occurs. We performed a monocentric pilot study to investigate its prevalence in the very elderly and to assess its potential influence on blood pressure (BP) goals during antihypertensive treatment. METHODS: All patients≥90 years of a primary care medical ward were prospectively included over 15 months. Ultrasound exams of the precerebral arteries were offered to all elderly patients for routine evaluation of their cardiovascular risk. Frequencies of stenosed common, internal and external carotid arteries (CCA, ICA, ECA) were analyzed together with clinical BP and antihypertensive therapy. Patients with circulatory shock and readmissions were excluded. RESULTS: Sixty-three patients aged 92±3 years (78% female) hospitalized for a median of 11 days were included. On admission, 76% were on antihypertensive drugs vs. 86% at discharge. Mean admission BP was 149/77 vs. 129/72mmHg at discharge; systolic BP<140mmHg 36% vs 64% (P<0.05). Mean intima-media thickness (ACC, right/left) was 8.7/9.4mm. Prevalence of plaque or stenosis<60% was: CCA 19.0%, ICA 19.0%, ECA 31.7%, bulb 74.6%; of stenosis≥60%: CCA 0%, ICA 7.9%, ECA 19.0%, ICA bilateral 1.6% (unilateral occlusion 3.1%, no bilateral). Coincidence of systolic BP<120mmHg and ACI stenosis≥60% had a probability of 1-2%. CONCLUSION: Concerning the risk of brain ischemia due to carotid artery stenosis, a BP goal<140mmHg should be safe for most nonagenarians. If individual BP goals are lower, searching for significant stenosis by ultrasound may be useful.

Simultaneous feedback control of plasma rotation and stored energy on NSTX-U using neoclassical toroidal viscosity and neutral beam injection.

A model-based feedback system is presented enabling the simultaneous control of the stored energy through ßn and the toroidal rotation profile of the plasma in National Spherical Torus eXperiment Upgrade device. Actuation is obtained using the momentum from six injected neutral beams and the neoclassical toroidal viscosity generated by applying three-dimensional magnetic fields. Based on a model of the momentum diffusion and torque balance, a feedback controller is designed and tested in closed-loop simulations using TRANSP, a time dependent transport analysis code, in predictive mode. Promising results for the ongoing experimental implementation of controllers are obtained.

l-Lysine Acts as a Serotonin Type 4 Receptor Antagonist to Counteract In Vitro and In Vivo the Stimulatory Effect of Serotonergic Agents on Aldosterone Secretion in Man.

In the normal human adrenal gland, serotonin (5-HT) stimulates aldosterone secretion through the 5-HT4 receptor (5-HT4R). However, the physiological role of the serotonergic control of adrenocortical function is not known. In the present study, we have investigated the ability of l-Lysine, which has been shown to act as a 5-HT4 receptor antagonist, to counteract in vitro and in vivo the stimulatory effect of 5-HT4R agonists on aldosterone production. l-Lysine was found to inhibit aldosterone production induced by 5-HT and the 5-HT4R agonists BIMU8 from cultured human adrenocortical cells. The action of l-Lysine (4.95 g/day orally) on the adrenal cortex was also evaluated in 20 healthy volunteers in a double blind, cross-over, placebo controlled study. l-Lysine had no significant influence on basal plasma aldosterone levels and the aldosterone responses to upright posture, tetracosactide, and low sodium diet (10 mmol/day for 3 days). Conversely, l-Lysine significantly reduced the surge of plasma aldosterone induced by metoclopramide indicating that l-Lysine is able to efficiently antagonize the adrenal 5-HT4 receptors in vivo. These results suggest that l-Lysine supplementation may represent a new treatment of primary adrenal diseases in which corticosteroid hypersecretion is driven by overexpressed 5-HT4 receptors.

Lactose malabsorption in systemic sclerosis.

BACKGROUND: There are no studies on systemic sclerosis (SSc) assessing the relationship between food intake, especially lactose, and gastrointestinal dysfunction. AIM: To determine the prevalence of lactose malabsorption, using lactose breath test, in patients with SSc. To evaluate the correlation between lactose malabsorption and gastrointestinal involvement. To predict which SSc patients exhibit lactose malabsorption. METHODS: Seventy-seven consecutive Caucasian patients with SSc and 20 control subjects underwent lactose breath test. All patients also completed a questionnaire on digestive symptoms, and a global symptom score (GSS) was calculated. RESULTS: The prevalence of lactose malabsorption was higher in SSc patients than in controls (44.3% vs. 10%; P = 0.004). We observed a marked correlation between the presence of lactose malabsorption and: higher values of GSS (P < 0.0001); severe oesophageal (P = 0.018) and small intestinal (P = 0.04) motor disorders; and joint involvement (P = 0.019). Furthermore, in SSc patients with symptomatic lactose malabsorption, the median value of GSS of digestive symptoms was lower after initiation of lactose-free diet (P < 0.0001). CONCLUSIONS: Our study underscores the fact that lactose malabsorption often occurs in patients with systemic sclerosis. Furthermore, our findings highlight the fact that lactose breath test is a helpful, noninvasive method, by identifying the group of patients with systemic sclerosis with symptomatic lactose malabsorption that may benefit from a reduction in lactose intake.

Remission from substance use disorders: A systematic review and meta-analysis.

OBJECTIVE: This paper presents a systematic review and meta-analysis of available evidence on remission rates for substance use disorders (SUDs), providing weighted mean estimates of SUD remission rates. The review also explores study-level characteristics that may explain variations in remission rates across studies. METHODS: A comprehensive search strategy identified studies published between 2000 and 2015 with follow-up periods of at least three years or reported lifetime remission outcomes for potential inclusion in the review. Remission was defined as not meeting diagnostic criteria for abuse or dependence for a minimum period of six months, as of final follow-up. A single-group summary meta-analysis was performed. Pooled estimated annual remission rates (PEARRs) were calculated. Meta-regression techniques and subgroup analyses were used to explore the association between study remission rates and key selected variables. RESULTS: Of 8855 studies identified, 21 met the eligibility criteria. The results suggested that 35.0% to 54.4% of individuals with SUDs achieved remission, and this occurred after a mean follow-up period of 17 years. The PEARRs projected few cases of SUD remission, between 6.8% and 9.1% in any given year. Studies that reported higher remission rates had longer follow-up periods, and lower sample retention rates. CONCLUSIONS: Results support the contention that SUDs are more likely to be "chronic" or long term disorders than acute disorders for a substantial number of individuals. However, more longitudinal research is required. Treatment geared to chronicity, such as assertive community treatment and intensive case management, needs to be more readily available for SUD populations.

Incremental Value (Bayesian Framework) of Thoracic Ultrasonography over Thoracic Auscultation for Diagnosis of Bronchopneumonia in Preweaned Dairy Calves.

BACKGROUND: Thoracic ultrasonography (TUS) is a specific and relatively sensitive method to diagnose bronchopneumonia (BP) in dairy calves. Unfortunately, as it requires specific training and equipment, veterinarians typically base their diagnosis on thoracic auscultation (AUSC), which is rapid and easy to perform. HYPOTHESIS/OBJECTIVES: We hypothesized that the use of TUS, in addition to AUSC, can significantly increase accuracy of BP diagnosis. Therefore, the objectives were to (i) determine the incremental value of TUS over AUSC for diagnosis of BP in preweaned dairy calves and (ii) assess diagnostic accuracy of AUSC. ANIMALS: Two hundred and nine dairy calves (<1 month of age) were enrolled in this cross-sectional study. METHODS: Prospective cross-sectional study. All calves from a veal calves unit were examined (independent operators) using the Wisconsin Calf Respiratory Scoring Criteria (CRSC), AUSC, and TUS. A Bayesian latent class approach was used to estimate the incremental value of AUSC over TUS (integrated discrimination improvement [IDI]) and the diagnostic accuracy of AUSC. RESULTS: Abnormal CRSC, AUSC, and TUS were recorded in 3.3, 53.1, and 23.9% of calves, respectively. AUSC was sensitive (72.9%; 95% Bayesian credible interval [BCI]: 50.1-96.4%), but not specific (53.3%; 95% BCI: 43.3-64.0%) to diagnose BP. Compared to AUSC, TUS was more specific (92.9%; 95% BCI: 86.5-97.1%), but had similar sensitivity (76.5%; 95% BCI: 60.2-88.8%). The incremental value of TUS over AUSC was high (IDI = 43.7%; 5% BCI: 22.0-63.0%) significantly improving proportions of sick and healthy calves appropriately classified. CONCLUSIONS AND CLINICAL IMPORTANCE: The use of TUS over AUSC significantly improved accuracy of BP diagnosis in dairy calves.

Hypoxia regulates global membrane protein endocytosis through caveolin-1 in cancer cells.

Hypoxia promotes tumour aggressiveness and resistance of cancers to oncological treatment. The identification of cancer cell internalizing antigens for drug targeting to the hypoxic tumour niche remains a challenge of high clinical relevance. Here we show that hypoxia down-regulates the surface proteome at the global level and, more specifically, membrane proteome internalization. We find that hypoxic down-regulation of constitutive endocytosis is HIF-independent, and involves caveolin-1-mediated inhibition of dynamin-dependent, membrane raft endocytosis. Caveolin-1 overexpression inhibits protein internalization, suggesting a general negative regulatory role of caveolin-1 in endocytosis. In contrast to this global inhibitory effect, we identify several proteins that can override caveolin-1 negative regulation, exhibiting increased internalization at hypoxia. We demonstrate antibody-mediated cytotoxin delivery and killing specifically of hypoxic cells through one of these proteins, carbonic anhydrase IX. Our data reveal that caveolin-1 modulates cell-surface proteome turnover at hypoxia with potential implications for specific targeting of the hypoxic tumour microenvironment.

Long term outcome of patients with low level of cryoglobulin (<0.05g/L).

OBJECTIVES: To date, no studies have yet assessed the characteristics of non-HCV patients with low level of cryoglobulin (≤0.05 g/L). The aims of the current study were thus to: 1) determine the prevalence of cryoglobulin ≤0.05 g/L in patients with non-HCV cryoglobulin; and 2) compare clinical features and long term outcome, including organ complications and mortality rate, between non-HCV patients with cryoglobulin level ≤0.05 g/L and those exhibiting cryoglobulin level >0.05 g/L. METHODS: Among 6379 cryoglobulin testing, cryoglobulin was detected in 618 patients (9.69% of cases); of these 618 patients, 453 non-HCV patients were included in the study. The medical records of these patients were reviewed. RESULTS: Of the 453 non-HCV cryoglobulin-positive patients, 265 (58.6%) exhibited cryoglobulin level ≤0.05 g/L. We showed that patients with cryoglobulin level ≤0.05 g/L had: 1) less commonly: palpable purpura (p<0.001), digital ulcers (p=0.006), peripheral neurologic involvement (p=0.03) and renal impairment (p=0.03); and 2) lower median values of ESR (p<0.001) and C-reactive protein (p=0.001). The patients with cryoglobulin level ≤0.05 g/L less often experienced infections (p=0.04) and hematological malignancies (p=0.01); both groups did not differ regarding prevalence of connective tissue diseases and solid tumors. Mortality rate was as high as 13.6% in patients with cryoglobulin level ≤0.05 g/L; death was mainly due to: solid tumors (16.6%), cardiovascular complications (13.8%), hematological malignancies (11.1%), infections (8.3%), pulmonary/renal complications of cryoglobulin (8.3%) and connective tissue diseases (8.3%). CONCLUSION: Our study shows a high prevalence of cryoglobulin level ≤0.05 g/L in clinical practice. Our findings further underscore that non-HCV cryoglobulin level ≤0.05 g/L may be responsible for severe renal and neurological complications, leading to high morbidity and mortality in these patients. Thus, our data suggest that both appropriate therapy and close follow-up may be required to improve such patients' outcome.

Do endoflip assessments of anal sphincter distensibility provide more information on patients with fecal incontinence than high-resolution anal manometry?

BACKGROUND: Anal manometry is the standard technique for evaluating anal sphincter function. However, the functional lumen imaging probe (EndoFLIP(®) ) can be used to measure sphincter distensibility during volume-controlled distensions. Our aims were (i) to assess anal distensibility in patients with fecal incontinence (FI) and in healthy subjects using the EndoFLIP(®) and (ii) to compare the results with anal pressures measured by 3D high-resolution manometry (3D-HRM) to determine whether the EndoFLIP(®) was more sensitive and specific for diagnosing FI than 3D-HRM. METHODS: EndoFLIP(®) and 3D-HRM assessments of 34 female FI patients and 40 healthy female subjects were performed. Anal distensibility was measured as the median cross-sectional area at the narrowest point divided by the corresponding intra-bag pressure at rest and during peak voluntary contraction and was expressed in mm(2) /mmHg. KEY RESULTS: A 40-mL anal distensibility index was selected for further comparisons as it provided the best discrimination between the FI patients and the healthy subjects. The index was significantly higher in the FI patients than in the healthy subjects at rest (p = 1.10(-4) ) and during voluntary contraction (p = 1.10(-4) ). The index at rest and during voluntary contraction appeared to be more appropriate than anal pressures for discriminating between FI patients and healthy subjects. CONCLUSIONS & INFERENCES: The present study confirmed that FI is associated with an abnormally high distensibility index at rest and during voluntary contraction. The ability of the distensibility index to discriminate between FI patients and healthy subjects was significantly better than anal pressure.

[Nurse delivery of oral contraception following an initial prescription for minors and uninsured patients in family planning centers of the Val-de-Marne]. / Délivrance par l'infirmière de la contraception orale suite à une prescription médicale initiale aux mineurs et aux non-assurés sociaux dans les centres de planification et d'éducation familiale du Val-de-Marne.

BACKGROUND: Since 2012 in France, nurses are allowed to renew the medical prescription of oral contraceptives (OC). To support this plan, a service protocol in family planning centers allows nurse delivery of OC. MATERIALS AND METHODS: This is a pilot feasibility study. After a medical prescription of OC, the nurse is authorized to deliver OC for 3months after a nursing interview. The duration of the nursing follow-up is determined by the physician. RESULTS: A total of 244 nurses interviews of 170 women were conducted between January 2012 and July 2013. All women have benefited from a delivery of contraceptives by the nurse. Analysis shows that 40 interviews (16%) had one or more abnormal criteria. Of these, more than a quarter found poor tolerance of contraception and/or the appearance of gynecological symptoms (27%) or unprotected sex with a new partner (25%). In these cases, an orientation to the physician was more frequent (85% versus 62%, P=0.005) and faster (median 33days versus 90days, P<0.001) than if the nurse interview was normal. CONCLUSION: Our study shows the feasibility of delivery protocol of oral contraception by nurses following an initial prescription by the physician.

Is coracoclavicular stabilisation alone sufficient for the endoscopic treatment of severe acromioclavicular joint dislocation (Rockwood types III, IV, and V)?

BACKGROUND: The primary objective was to evaluate correlations linking anatomical to functional outcomes after endoscopically assisted repair of acute acromioclavicular joint dislocation (ACJD). HYPOTHESIS: Combined acromioclavicular and coracoclavicular stabilisation improves radiological outcomes compared to coracoclavicular stabilisation alone. MATERIAL AND METHODS: A prospective multicentre study was performed. Clinical outcome measures were pain intensity on a visual analogue scale (VAS), subjective functional impairment (QuickDASH score), and Constant's score. Anatomical outcomes were assessed on standard radiographs (anteroposterior view of the acromioclavicular girdle and bilateral axillary views) obtained preoperatively and postoperatively and on postoperative dynamic radiographs taken as described by Tauber et al. RESULTS: Of 116 patients with acute ACJD included in the study, 48% had type III, 30% type IV, and 22% type V ACJD according to the Rockwood classification. Coracoclavicular stabilisation was achieved using a double endobutton in 93% of patients, and concomitant acromioclavicular stabilisation was performed in 50% of patients. The objective functional outcome was good, with an unweighted Constant's score ≥ 85/100 and a subjective QuickDASH functional disability score ≤ 10 in 75% of patients. The radiographic analysis showed significant improvements from the preoperative to the 1-year postoperative values in the vertical plane (decrease in the coracoclavicular ratio from 214 to 128%, p=10(-6)) and in the horizontal plane (decrease in posterior displacement from 4 to 0mm, p=5×10(-5)). The anatomical outcome correlated significantly with the functional outcome (absolute R value=0.19 and p=0.045). We found no statistically significant differences across the various types of constructs used. Intra-operative control of the acromioclavicular joint did not improve the result. Implantation of a biological graft significantly improved both the anatomical outcome in the vertical plane (p=0.04) and acromioclavicular stabilisation in the horizontal plane (p=0.02). The coracoclavicular ratio on the anteroposterior radiograph was adversely affected by a longer time from injury to surgery (p=0.02) and by a higher body mass index (BMI) (p=0.006). High BMI also had a negative effect on the difference in the distance separating the anterior edge of the acromion from the anterior edge of the clavicle between the injured and uninjured sides, as assessed on the axillary views (p=0.009). CONCLUSION: This study demonstrates that acute ACJD requires stabilisation in both planes, i.e., at the coracoclavicular junction and at the acromioclavicular joint. Coracoclavicular stabilisation alone is not sufficient, regardless of the type of implant used. Implantation of a biological graft should be considered when the time from injury to surgery is longer than 10days. The weight of the upper limb should be taken into account, with 6weeks of immobilisation to unload the construct in patients who have high BMI values. LEVEL OF EVIDENCE: II, prospective non-randomised comparative study.
