Examining men as victims of intimate partner violence in a French forensic department.

OBJECTIVE: Intimate partner violence (IPV) is a particular type of interpersonal violence, in which violence is performed between individuals involved in an intimate relationship. Johnson developed a typology in which he differentiates common couple violence (CCV) from intimate terrorism (IT). We led a descriptive review of the cases of men treated at the victimology unit of the forensic department of Nancy for IPV-related abuse. METHOD: We retrospectively investigated our database to extract every file of male patient treated at the victimology unit of the forensic department of Nancy (France) from 2014 to 2019 for IPV-related abuse. We studied several parameters relating to the protagonists and their relationship, the violence endured, and the statements made during the forensic consultation. An attempt to perform Johnson's typology was made. RESULTS: We had a total of 226 consultations. The age of the patients ranged from 18 to 88 years old. Almost all patients experienced physical violence. Psychological violence was noted in 138 files. Concerning Johnson's typology, we identified 92 cases consistent with the definition of CCV and 46 cases compatible with IT. CONCLUSION: Male victims of IPV are now backed by an ever-growing corpus of studies that sheds an opportune light upon this challenging topic. Sadly, too many remain discredited and unaccounted for. We believe that escaping a gender-opposing conception in favor of a global understanding of this phenomenon would be of benefit to both men and women.

Determinants of total incapacity to work duration among 231 victims of school violence in France.

INTRODUCTION: This study aimed to identify the factors that may influence the duration of the total incapacity to work (TIW) among victims of school violence from the perspective of clinical forensics practice. METHODS: It used a cross-sectional design to collect data from school violence victims examined at a French forensic unit following a judicial requisition. Logistic regression models were used to identify whether the victim's characteristics, the circumstances of the violence, or the evaluation itself could predict a TIW duration equal to or greater than 2 days. RESULTS: Among 231 victims of school violence, the presence of traumatic injuries such as sprains or broken bones (OR=19.8; 95% CI, 1.7-23.4, p = 0.018), bruises (OR=6.3; 95% CI, 1.5-26.8, p = 0.007), and muscle contractures (OR=7.3; 95% CI, 2.0-26.2, p = 0.007) were the main risk determinants for a longer TIW. Factors with a mild impact were the presence of ecchymosis (OR=3.8; 95% CI, 1.4-9.9, p = 0.007), anxiety (OR=3.4, 95% CI, 1.6-7.1, p = 0.001), female physician (OR=2.5, 95% CI, 1.2-5.1, p = 0.016), and the presence of a psychological follow-up for the victim or the need for a psychological consultation (OR=3.6, 95% CI, 1.2-10.7 and OR=4.7, 95% CI, 1.9-11.5, p = 0.001). CONCLUSION: These results highlight the importance of developing a more uniform model in determining TIW, whatever the physician's characteristics, through screening and reporting methods for both physical and psychological symptoms.

[Prospective forensic study on the characterization of genital examination in women with consented sexual activity]. / Étude médico-légale prospective sur la caractérisation de l'examen génital chez des femmes ayant une activité sexuelle consentie.

OBJECTIVE: The number of women victims of sexual assault remains high, despite prevention and information campaigns. These victims can be adolescent girls, women of childbearing age or postmenopausal women. As part of examinations of victims of sexual assault, the morpho-anatomical diversity of the female genitalia requires knowledge of the physiological variations existing by the practitioners caring for these victims. Our work aimed to describe and characterize the genital examination of women with consented sexual activity. METHOD: Our cohort consisted of 196 women aged 14 to 81, examined in the context of medical gynecology consultations in two French maternity hospitals. RESULTS: Recent genital traumatic injuries were found in 12.8% of women whose last sexual intercourse was less than 5days old. Intact hymens, free from traumatic tearing despite regular sexual activity, were present in 10.7% of these women. CONCLUSION: Thus, in many cases, genital examination alone cannot confirm or deny the existence of prior sexual intercourse, whether or not it was consented to. The development of work on data on female genital anatomy would make it possible to optimize the medico legal care of victims of sexual assault.

[Para-arortic lymhadenectomy and pelvic gynecological cancers: Extraperitoneal or transperitoneal laparoscopy?] / Curage lombo-aortique et cancers gynécologiques pelviens : cœlioscopie rétroperitonéale ou transpéritonéale ?

INTRODUCTION: Para-aortic lymphadenectomy plays a fundamental role in the surgical management of pelvic gynecological cancers. Two laparoscopic approaches exist: the transperitoneal (TP) and the extraperitoneal (EP). The aim of this study was to compare these 2 approaches in terms of surgical outcomes, specially the number of removed lymph nodes according to the surgical technique, and morbidity. MATERIALS AND METHOD: A single-center retrospective study was carried out at the Lariboisiere University Hospital between January 2011 and March 2020 including all patients who underwent para-aortic lymphadenectomy for the management of a pelvic gynecological cancer (cervix, endometrium, ovary). Univariate and multivariate analysis (logistic regression) were performed to compare the TP and the EP groups. RESULTS: 143 patients were included: 74 in the TP group and 69 in the RP group. The total duration of surgery was 220.8minutes in the TP group and 166.4minutes in the EP group (P<0.001 in multivariate analysis). No significant difference between groups were found in the average total number of lymph nodes removed but there was a statistically significant difference in the average latero-aortic number of lymph nodes removed: 8.5 lymph nodes in the TP group and 11.3 lymph nodes in the group RP (P<0.001 in multivariate analysis). There was no difference between groups in peri and postoperative morbidity. CONCLUSION: EP para-aortic lymphadenectomy reduces duration of surgery and increases the average latero-aortic number of lymph nodes removed with same morbidity compared to TP para-aortic lymphadenectomy, this confirming its preferred indication in endometrial and in cervical cancers.

Vehicle-assisted ligature decapitation: A case report and a review of the literature.

Decapitation resulting by vehicle-assisted ligature strangulation is a suicide method rarely described in the literature. The lesions observed at autopsy have a common morphology with to those found in post-hanging decapitation. They depend on the force applied by the acceleration of the vehicle, the slope of the road and the characteristics of the link used. They can also mimic a stabbing homicide. We report the case of a 43-year-old man who used a long steel rope, attached between his neck and a streetlight, and started his vehicle, causing a complete decapitation. The results of the autopsy provided information on the morphology of the cervical lesions, but also on the causes of death. In spite of decapitation, the histological examination of the organs confirmed the presence of asphyxiation process by a mechanical origin that occurred before decapitation.

[First trends of change in mortality by suicide in Nord-Pas-de-Calais since VigilanS]. / « Premières analyses de mortalité par suicide en Nord-Pas-de-Calais depuis l'implantation de VigilanS ¼.

INTRODUCTION: In terms of suicide prevention, population-based prevention devices often struggle to demonstrate an effect in terms of reducing suicidal acts of suicide, often focusing on the evolution of the number of suicide attempts, on time too short to statistically interpret changes in mortality. The consolidated figures for mortality in France are provided by the CepiDC with a delay of approximately three years. We therefore had to try to work with an approximation of the phenomenon, and we tested the proxy value of the enumeration of corpses, body examinations and medico-legal autopsies for suicide by the forensic doctors of the Nord-Pas-de-Calais region in France. In parallel, we conducted a comprehensive mortality study for 2016 in the VigilanS cohort. METHOD: By measuring the evolution of the number of body lifts for suicide by the Department of Forensic Medicine of the region, for the 3 years before VigilanS (2012-2014) compared to the 3 years since VigilanS (2015-2017). The deaths of patients of the VigilanS cohort were identified by calling the city halls of birth and domicile of all patients integrating the device in 2016. The cause of death was then characterized by contact of the attending physician. RESULTS: We observe an average decrease in suicide mortality of 9.9% (-12% for men, +0.3% for women). The exhaustive analysis of suicide mortality in the VigilanS cohort in 2016 found 19 deaths, of which 14 by suicide, or 0.4% of patients. This observed mortality rate in the VigilanS cohort in 2016 is significantly below the expected threshold in the literature (1 to 2% in the year following TS). CONCLUSION: It seems possible to reach the 2020 target for a 10% decrease in suicidal behavior in industrialized countries by 2020. The VigilanS device could therefore be protective in terms of suicide mortality.

[Pulmonary crackles, what does the clinician hear?]. / Craquements pulmonaires: que perçoit le clinicien ?

INTRODUCTION: The overall duration of a pulmonary crackle is usually less than 20-30 ms but psychoacoustics demonstrates that an acoustical event with a duration of less than 20-40 ms cannot be estimated in terms of pitch and duration. We pose the hypothesis that the main resonant information is contained into the breath sounds following the crackle. METHODS: Eight patients with COPD, viral pneumonia, bronchiectasis, congestive heart failure, hypoproteinemia and fibrosing alveolitis were recruited for this study. Thirty-six crackles were analyzed in time and frequency domains; 12 in each category of low, medium and high frequencies. The acoustic features of the crackles, their segments (initial deflection width, first cycle duration, two cycles duration, decay segment) and the breath sounds following the crackles were compared. RESULTS: The study confirms the differences between the three crackles categories in time and frequency domains. No statistical differences were found between the decay segments and breath sounds in each category. CONCLUSIONS: Breath sounds modified by lung tissue density could be the main resonators determining the fundamental transmission frequencies of crackle signals. Combined acoustic analysis of crackles and breath sounds could replace single analysis of isolated crackles.

Cyclodextrin curcumin formulation improves outcome in a preclinical pig model of marginal kidney transplantation.

Decreasing organ quality is prompting research toward new methods to alleviate ischemia reperfusion injury (IRI). Oxidative stress and nuclear factor kappa beta (NF-κB) activation are well-described elements of IRI. We added cyclodextrin-complexed curcumin (CDC), a potent antioxidant and NF-κB inhibitor, to University of Wisconsin (UW) solution (Belzer's Solution, Viaspan), one of the most effective clinically approved preservative solutions. The effects of CDC were evaluated on pig endothelial cells and in an autologous donation after circulatory death (DCD) kidney transplantation model in large white pigs. CDC allowed rapid and lasting uptake of curcumin into cells. In vitro, CDC decreased mitochondrial loss of function, improved viability and lowered endothelial activation. In vivo, CDC improved function recovery, lowered histological injury and doubled animal survival (83.3% vs. 41.7%). At 3 months, immunohistochemical staining for epithelial-to-mesenchymal transition (EMT) and fibrosis markers was intense in UW grafts while it remained limited in the UW + CDC group. Transcriptional analysis showed that CDC treatment protected against up-regulation of several pathophysiological pathways leading to inflammation, EMT and fibrosis. Thus, use of CDC in a preclinical transplantation model with stringent IRI rescued kidney grafts from an unfavorable prognosis. As curcumin has proved well tolerated and nontoxic, this strategy shows promise for translation to the clinic.

Autochthonous case of dengue in France, October 2013.

In October 2013, autochthonous dengue fever was diagnosed in a laboratory technician in Bouches-du-Rhone, southern France, a department colonised by Aedes albopictus since 2010. After ruling out occupational contamination, we identified the likely chain of local vector-borne transmission from which the autochthonous case arose. Though limited, this second occurrence of autochthonous dengue transmission in France highlights that efforts should be continued to rapidly detect dengue virus introduction and prevent its further dissemination in France.

Evaluation and impact of residual disease in locally advanced cervical cancer after concurrent chemoradiation therapy: results of a multicenter study.

BACKGROUND: The aim of this study was to evaluate the diagnosis and impact of residual disease (RD) after concurrent chemoradiation therapy (CRT) in locally advanced cervical cancer (FIGO IB2-IVA). METHODS: This retrospective multicenter study included 159 patients who were treated with completion surgery after CRT between 2006 and 2012. Magnetic resonance imaging (MRI) was performed 4-6 weeks after CRT and compared to pathological evidence of residual disease. Kaplan-Meier survival curves were plotted and univariate/multivariate analyses were performed to assess the association between RD and the outcome. RESULTS: Residual disease was present in 45.3% of the patients and detected by MRI in 57.1%. The MRI had a 29.2% false positive rate and an 11.1% false negative rate. The overall survival (OS) rates at 3 and 5 years were 78.6% (CI 95% [71%-86.9%]) and 76.5% (CI 95% [68.2%-85.7%]), respectively. The disease free survival (DFS) rates at 3 and 5 years were 73.4% (CI 95% [65.6%-82%]) and 71.1% (CI 95% [62.7%-80.1%]), respectively. RD greater than 10 mm decreased DFS (HR = 4.84, p = 0.03), whereas RD between 1 and 10 mm (HR = 0.31, p = 0.58) and less than 1 mm (HR = 0.37, p = 0.54) had no impact on DFS. The OS was not changed by RD. DISCUSSION: The MRI accuracy value is not sufficient to select patients who might benefit from completion surgery. Residual disease over 10 mm decreased DFS but did not impact OS.

COPD awareness survey: do Belgian pulmonary physicians comply with the GOLD guidelines 2010?

Chronic Obstructive Pulmonary Disease (COPD) is underestimated, underdiagnosed and often under-treated in the general population. A survey of 17 structured questions, delivered to all Belgian pulmonary physicians (PPs) (116 responses), evaluated diagnosis and treatment strategies in accordance with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines 2010 and assessed opinions about the importance of diurnal variation of COPD symptoms. All COPD diagnoses (37% new cases) were spirometry confirmed. Main diagnostic parameters were symptoms (99%), external risk factors (99%), clinical examination (97%), exacerbations (96%) and patient mobility (96%). FEV1 (forced expiratory volume in 1s) (97%) or FEV1/FVC (ratio of FEV1 to forced vital capacity) (93%) were used most to assess diagnosis and severity. The 3 most important therapeutic objectives were symptom relief, preventing exacerbations, and improving quality of life; if these were not reached, the preferred strategy (60% of PPs) was adding another medication. Treatment strategies varied with COPD stage: short-acting beta2-agonists (90%) and short-acting anti-cholinergics (59%) were used for GOLD I disease, whereas for higher stages long-acting beta2-agonists (36-48%) and long-acting anti-cholinergics (79%) were given with inhaled corticosteroids (21-67%). Symptoms were perceived to vary throughout the day, affecting quality of life (97%) and mobility (89%). In particular, respiratory symptoms were more severe in the morning (51-92%), leading PPs to adapt treatment (69%). This survey demonstrated that management of COPD by PPs in Belgium is generally in line with the GOLD guidelines 2010 and that they perceive morning symptoms as being frequent and having an impact on patient's life.

Clinical, virological and epidemiological assessment of 2009 influenza A (H1N1) pandemic in a Belgian university hospital.

BACKGROUND: Recommendations were applied before and during the Belgian pandemic (2009) H1N1 influenza wave at a university hospital (420 beds), for optimizing isolation processes and therapeutic management of possible and confirmed infected cases. METHODS: All patients presenting to the Emergency Department (ED) between August 1st and December 31st 2009 were screened for ILI symptoms, and were isolated for clinical assessment in case of positive screening. Patients categorized as possible influenza cases and who required hospitalization were isolated in dedicated wards. Specific diagnostic algorithms were implemented. Medical charts were retrospectively reviewed and matched with results of the microbiology laboratory. Patient's characteristics were analyzed, the contribution of laboratory diagnosis on therapy and lengh of stay (LOS) in isolation was also assessed. RESULTS: 310 patients out of 6068 had a positive screening for ILI, of these, 265 were retained as possible influenza cases and 139 required hospitalization. Twenty-eight children (8 requiring hospitalization) and 20 hospitalized adult patients had confirmed influenza infection. Five adult patients were admitted to the intensive care unit (ICU), 3 requiring extracorporeal membrane oxygenation (ECMO). There was no death related to the new influenza strain. The majority of confirmed patients were diagnosed during the Belgian epidemic wave, with a sensitivity of antigen detection of 50% in children and 35% in adults comparatively to real-time PCR (RT-PCR). CONCLUSIONS: The impact of (2009) H1N1 pandemic influenza remained limited, except for ICU patients requiring ECMO. Implementation of screening, isolation, and virological diagnosis processes led to significant improvement of patient management.

Treatment planning and delivery evaluation of volumetric modulated arc therapy for stereotactic body radiotherapy of spinal tumours: impact of arc discretization in planning system.

The purpose of this study was to compare single arc volumetric modulated arc therapy (VMAT) to intensity modulated radiotherapy (IMRT) for spine SBRT in terms of target coverage, organ at risk (OAR) sparing and delivery performance. VMAT plans with 91 control points (VMAT-91CP) were generated for 15 spine metastases patients previously treated with a nine-field IMRT technique. VMAT and IMRT plans were compared based on target coverage, maximum spinal cord dose, maximum plan dose and volume of normal tissue receiving 20% to 80% of the prescribed dose. Treatment delivery time and monitor units (MU) were measured to determine delivery efficiency. To assess the impact of arc discretization in the treatment planning system (TPS), the VMAT-91CP plans were modified by almost doubling the number of CPs (VMAT-181CP). Planned-to-delivered dose agreement for both techniques was assessed using two types of 3D detector arrays.VMAT-91CP target coverage was equivalent to IMRT while maintaining or improving spinal cord sparing. This was achieved without increasing the volume of normal tissue receiving low or intermediate dose levels. Planned-to-delivered dose agreement equivalent to IMRT was achieved with VMAT, but required decreasing the CP angular spacing from 4° to 2° (VMAT-181CP plans). On average, VMAT-181CP plans reduced delivery time by 53% compared to IMRT. Single-arc VMAT for spine SBRT improved delivery efficiency while maintaining target coverage and OAR sparing compared to IMRT. VMAT plans generated with a CP gantry angular spacing of 2° is recommended to avoid a discretization effect in the TPS and ensure acceptable planned-to-delivered dose agreement.

[Evaluation of the COPD Assessment Test in patients with stable COPD]. / Évaluation du COPD Assessment Test (CAT) chez des patients BPCO en état stable.

INTRODUCTION: The COPD Assessment Test (CAT) is a new simple tool developed for assessing health-related quality of life in patients with COPD. The characteristics of the score derived from the CAT as a function of various parameters of evaluation of the severity of COPD remain to be described. METHODS: The CAT was submitted prospectively to 213 consecutive stable ambulatory COPD patients assessed in a tertiary care hospital. The discriminative value of the CAT was analysed as well as its association with various parameters of interest. RESULTS: The progressive increase in the CAT score with the severity of the disease as assessed by the GOLD stages and the BODE index, as well as the level of dyspnoea, demonstrates the discriminative capacity of the CAT. In multivariate analysis, only the RV/TLC (residual volume/total lung capacity) and the 6-minute walk distance were significantly associated with the CAT score, explaining only 27 % of its variability. The inclusion of dyspnoea in the model explained 42 % of the CAT score variability, only dyspnoea and the RV/TLC ratio being significantly associated. CONCLUSION: The CAT has good discriminative characteristics that are similar to more complex tools designed to assess health-related quality of life in patients with COPD.

[Tours experience of endovascular treatment in superior vena cava syndrome]. / Traitement curatif endovasculaire du syndrome de la veine cave supérieure, étude de cas de l'expérience tourangelle.

Superior vena cava syndrome is a clinical entity including symptoms arising from an obstruction of return flow in the superior vena cava. It can be life threatening. In the context of lung cancer, by far the most prominent etiology (nine of ten cases in our series), the condition is particularly serious, with only 20% survival at one year. Medical treatment may be insufficient, requiring surgical salvage. Palliative procedures are rapidly effective and well tolerated. We perform a first intention transluminal angioplasty under local anesthesia via the right femoral vein. This ultrasound-guided procedure enables insertion of a non-coated nitinol stent. The success rate in our hands has been 90%. Clinical improvement is constant and immediate with long-term efficacy. The early and late post-operative period is uneventful.

A performance evaluation of three membrane bioreactor systems: aerobic, anaerobic, and attached-growth.

Water sustainability is essential for meeting human needs for drinking water and sanitation in both developing and developed countries. Reuse, decentralization, and low energy consumption are key objectives to achieve sustainability in wastewater treatment. Consideration of these objectives has led to the development of new and tailored technologies in order to balance societal needs with the protection of natural systems. Membrane bioreactors (MBRs) are one such technology. In this investigation, a comparison of MBR performance is presented. Laboratory-scale submerged aerobic MBR (AMBR), anaerobic MBR (AnMBR), and attached-growth aerobic MBR (AtMBR) systems were evaluated for treating domestic wastewater under the same operating conditions. Long-term chemical oxygen demand (COD) and total organic carbon (TOC) monitoring showed greater than 80% removal in the three systems. The AnMBR system required three months of acclimation prior to steady operation, compared to one month for the aerobic systems. The AnMBR system exhibited a constant mixed liquor suspended solids concentration at an infinite solids retention time (i.e. no solids wasting), while the aerobic MBR systems produced approximately 0.25 g of biomass per gram of COD removed. This suggests a more economical solids management associated with the AnMBR system. Critical flux experiments were performed to evaluate fouling potential of the MBR systems. Results showed similar critical flux values between the AMBR and the AnMBR systems, while the AtMBR system showed relatively higher critical flux value. This result suggests a positive role of the attached-growth media in controlling membrane fouling in MBR systems.
