[Systematic analysis of evaluations of Objective Structured Clinical Exam (OSCE) multiple circuits: Explanatory variables and inter-rater correlations]. / Analyse systématique des évaluations de circuits multiples d'examen clinique objectif structuré (ECOS) : variables explicatives et corrélations inter-évaluateurs.

INTRODUCTION: Objective Structured Clinical Examinations (OSCEs) assess professional performance in a simulated environment. Following their integration into the reform of the 2nd cycle of medical studies (R2C), this pedagogical modality was implemented in France. This study investigates the variability of students' OSCE scores, as well as their inter-rater reproducibility. METHODS: This single-center retrospective study covered several sessions of evaluative OSCE circuits conducted between January 2022 and June 2023. Variables collected were: baseline situation family, competency domain, presence of a standardized participant for stations; gender and professional status for evaluators; scores (global, clinical and communication skills), number of previously completed OSCE circuits and faculty scores for students. RESULTS: The variability of the overall score was explained mainly (79.7%, CI95% [77.4; 82.0]) by the station factor. The student factor and the circuit factor explained 7.5% [12.9; 20.2] and<0.01% [2.10-13; 2.10-9] respectively. The inter-rater intra-class correlation coefficient was 87.2% [86.4; 87.9] for the global score. Station characteristics (starting situation, domain) and evaluator characteristics (gender, status) were significantly associated with score variations. CONCLUSION: This first study on the variability of OSCE circuit scores in France shows good reproducibility with influence of station characteristics. In order to standardize circuits, variability linked to the domain competency should be considered as well.

Is it justified to search for cancer in patients with peripheral arterial disease?

BACKGROUND: Cancer is the leading cause of death in European countries, ahead of cardiovascular diseases. Cancer is also the most common co-morbidity among patients hospitalized for the management of cardiovascular diseases. Through an overview, we searched for the frequency and types of cancer associated with peripheral arterial disease (PAD) in order to address the relevance of cancer screening in patients with PAD. METHODS: We searched in PubMed database from 1996 to 2020 for retrospective and prospective cohort or cross-sectional or randomized studies evaluating the frequency of all types of cancer in patients with PAD excluding patients with aneurysmal disease. The keywords used were: peripheral arterial disease, arterial thrombosis, acute leg ischemia, critical leg ischemia, chronic leg ischemia, intermittent claudication, malignant tumor, cancer. RESULTS: Based on published studies, the frequency of cancer in patients with PAD varied widely from 3.8 to 30.4% depending on study design, population, method used to screen for cancer and study period. In medical records database and registers,cancer prevalence varied from 3,8% to 22,4% in 4 retrospective studies of patients with acute limb ischemia and from 10.5 to 30.4% in 3 prospective studies of patients with acute limb ischemia, critical ischemia or intermittent claudication. In 3 retrospective analyses from 2 population-based cohorts and health insurance claims data, incidence of cancer in patients with intermittent claudication, acute limb ischemia or peripheral arterial disease varied from 8% to 11.7%. The frequency of cancer in PAD patients appeared higher than in the general population. Tobacco-dependent cancers seemed to be the most common cancers in PAD. Cancers were also more frequent in case of anemia, amputation and iterative bypass thrombosis in few studies. CONCLUSION: Although there is no recommendation for cancer screening in patients with PAD, the high prevalence of cancer raises the question of screening patients at high risk such as those with acute or critical limb ischemia and especially in case of severe tobacco use, anemia, amputation and iterative bypass thrombosis. These results call for further studies with larger sample size and long term follow-up.

[Lower-limb peripheral arterial disease]. / Artériopathie oblitérante des membres inférieurs.

Peripheral arterial disease is a result of atheroma. This disease is frequent in subjects with vascular risk factors. This disease is also frequent in low income countries. The detection and the diagnosis of peripheral arterial disease is obtained by calculating the ankle brachial index. Patients with peripheral arterial disease are not always symptomatic thus explaining how this disease is under diagnosed. The symptoms can be absent, and especially in case of diabetes or in women. In case of peripheral arterial disease, atheroma often involves other arterial vascular networks especially the coronaries. An adapted treatment reduces the morbi-mortality linked to this disease. This treatment is based on the correction of the vascular risk factors and especially tobacco cessation, walking rehabilitation and drugs (antiplatelet agent, statin, renin angiotensin system blocker). In case of rest or critic ischemia, the first-line treatment is a revascularisation. In peripheral arterial disease, management of patients is often non optimal and therapeutic targets fairly often obtained.

Management of cancer-related thrombosis in the era of direct oral anticoagulants: A comprehensive review of the 2019 ITAC-CME clinical practice guidelines. On behalf of the Groupe Francophone Thrombose et Cancer (GFTC).

Venous thromboembolism (VTE) is a common disease complication in cancer patients and the second cause of death after cancer progression. VTE management and prophylaxis are critical in cancer patients, but effective therapy can be challenging because these patients are at higher risk of VTE recurrence and bleeding under anticoagulant treatment. Numerous published studies report inconsistent implementation of existing evidence-based clinical practice guidelines (CPG), including underutilization of thromboprophylaxis, and wide variability in clinical practice patterns across different countries and various practitioners. This review aims to summarize the 2019 ITAC-CME evidence-based CPGs for treatment and prophylaxis of cancer-related VTE, which include recommendations on the use of direct oral anticoagulants specifically in cancer patients. The guidelines underscore the gravity of developing VTE in cancer and recommend the best approaches for treating and preventing cancer-associated VTE, while minimizing unnecessary or over-treatment. Greater adherence to the 2019 ITAC guidelines could substantially decrease the burden of VTE and improve survival of cancer patients.

[Thrombophilias and peripheral arterial occlusive disease]. / Thrombophilies et artériopathie oblitérante des membres inférieurs.

Peripheral arterial occlusive disease is a frequent disease due to the classical vascular risk factors such as smoking, diabetes mellitus, dyslipidemia, and hypertension. Despite these risk factors, many thrombophilias (physiological inhibitors defects, Factor V Leiden and 20210A prothrombin gene variant, antiphospholipid antibodies, mild hyperhomocysteinemia 15-30micromol/l) can be evoked in some clinical forms of peripheral arterial occlusive disease. This paper provides a synthesis of the published data about this topic. Screening for these thrombophilias is justified in patients with venous thromboembolic disease, or signs of antiphospholipid syndrome and possibly in different situations such as premature atheroma of lower limbs, chronic ischaemia, evolutive disease despite adapted treatment and revascularisation failures without evident technical explanation. Except for the antiphospholipid syndrome, there is currently no consensus for systematic screening of thrombophilia and treatment in patients with peripheral arterial occlusive disease.

Performance analysis of walking of 10,000 regular users of a connected activity tracker.

BACKGROUND: According to the World Health Organization, individuals should walk 10,000 per day. Our aim was to determine the factors influencing this objective by using connected activity trackers. METHODS: Anonymized data of 10,000 regular users of the Withings pulse Ox over a 3-month period. RESULTS: Ratio men/women was 2.2, mean age 44.9±10.6 years, mean BMI 27.0±5.3kg/m2, proportion of individuals living in big towns 21.4%, proportion of physical activity<2 METs 66%. The frequency of achieving 10,000 daily steps was similar for work days, weekends and whole weeks. Mean number of daily steps, mean daily covered distances and slopes were higher during work days (P<0.0001); mean speed was higher during the weekends (P<0.0001). According to a quartile-repartition (percentages of use-days with 10,000 steps), the goal was more often achieved during work days (P<0.0001), if BMI<25kg/m2 (P<0.001), in individuals living in big towns (P<0.001) or having≥2 acquaintances to take up challenges (P<0.001). CONCLUSION: Connected activity trackers represent a valuable tool for evaluating the number of daily steps and for providing feedback to promote walking.

[College of the French Vascular Medicine Teachers (CEMV) statement: Arterial Doppler waveforms analysis (simplified Saint-Bonnet classification)]. / Recommandations du Collège des enseignants de médecine vasculaire (CEMV) : analyse des flux artériels Doppler (classification de Saint-Bonnet simplifiée).

Lower extremity peripheral artery disease is a frequent disease. Arterial Doppler waveforms analysis is a key element in vascular medicine, especially to diagnose lower peripheral artery disease. Although Doppler waveforms are often used, descriptions are highly heterogeneous. This review presents the simplified Saint-Bonnet classification that is tought to vascular medicine residents in order to homogenize arterial flow description.

[Prevalence of macrovascular arterial involvement of the 4 limbs in systemic sclerosis: About a case series of 14 patients]. / Prévalence de l'atteinte artérielle macrovasculaire des 4 membres dans la sclérodermie systémique : à propos de 14 patients.

INTRODUCTION: Trophic disorders of the extremities are a common complication of systemic sclerosis (SSc), mainly related to microvascular damage. However, SSc seems to be a risk factor for premature athero-thrombotic disease that can affect the peripheral arteries, participate in the occurrence of trophic disorders and promote the occurrence of infectious complications. The objective of this study was to assess the prevalence of arterial disease of the limbs in SSc patients. METHODS: Consecutive inclusions in the context of a multidisciplinary consultation centered on disability of the hand with collection of clinical data [cardiovascular risk factors (CVRF), history of trophic disorders of ischemic origin, peripheral pulse palpation, Allen maneuver the upper (UL) and lower limbs (LL)], and hemodynamic data (flow recorded by Doppler in radial, ulnar, anterior and posterior tibial arteries, and measurement of systolic indices ankles). RESULTS: Fourteen patients were included (11 right-handers, 2 left-handers, 1 ambidextrous). The sex-ratio male/female was 0.27 and the average age of 58.1±10.4 years. The main CVRF were age and smoking. In the UL, 42.8% of patients had a history of trophic disorders, Allen maneuver was abnormal for 35.7% of the superficial palmar arch, 42.9% of ulnar pulse were not perceived and there was no recordable flow in 25% of ulnar artery. In the LL, 14.3% of patients had already presented trophic disorders toes, Allen maneuver was abnormal for 15.4% of the posterior tibial artery, 25.6% of posterior tibial pulse were not perceived and flow of 15.4% of posterior tibial arteries was pathological. CONCLUSION: The distal macrovascular disease preferentially affecting the ulnar and posterior tibial arteries with a high frequency to the UL and two times less at LL. The pathophysiology is unclear but it could be a proper manifestation of SSc. It seems necessary that SSc patients have a strict balance of their CVRF and a screening of macrovascular arterial lesions. There is also the question of the place of an anti-atherosclerotic therapy in these patients.

Symptomatic lower-limb giant-cell arteritis: Characteristics, management and long-term outcome.

OBJECTIVE: To describe characteristics and long-term outcomes of the rare symptomatic lower-limb giant-cell arteritis (LL-GCA). METHODS: Retrospective analysis of 8 patients (6 women; mean±SD age, 63.6±10.9 years; follow-up, 137.3±57.3 months). RESULTS: Four patients satisfied≥3 American College of Rheumatology (ACR) GCA-classification criteria; 4 had<3 criteria and histological LL-GCA proof or associated typical upper-limb involvement. Patients had 2.1±1.1 vascular risk factors. Bilateral and rapidly progressive arterial claudication was the first LL sign; 2 had rest ischemia. Imaging-visualized most-to-least frequent inflammatory lesion localizations were: superficial femoral, popliteal, tibiofibular trunk, posterior tibial arteries. All received corticosteroids for 132±76.2 months; 2 required immunosuppressive agent adjunction. Only 3 required 1-6 revascularizations: twice during the first month post-diagnosis and twice later. Thromboendarterectomy and endovascular procedures did not work while bypasses were successful. LL-claudication regressed for 7 (10.5±12.1 months) and disappeared for 5 (16.8±9.8 months). Three patients stopped corticosteroids (26-90 months), 1 restarted 45 months later. Every patient relapsed once (23.9±26.7 months, mean corticosteroid dose: 0.28±0.30mg/kg/day). LL-GCA caused only 1 of the 4 deaths. CONCLUSION: Symptomatic LL-GCA attributable long-term mortality seems to be low despite frequent relapses and corticosteroid-dependence.

[Does antiaggregant therapy have a place in type II heparin-induced thrombocytopenia?]. / L'antiagrégation a-t-elle une place en cas de thrombopénie tardive induite par l'héparine?

We report a case of type II heparin-induced thrombocytopenia, which occurred after heart surgery in a 71-year-old female patient with several cardiovascular risk factors. The diagnosis of heparin-induced thrombopenia was suspected because association of multifocal arterial and venous thrombosis and detection of antiplatelet-factor 4 antibodies with a drop of more than 50% in the platelet count. Until diagnostic of heparin-induced thrombocytopenia was made, clopidogrel was introduced because of well-documented ischemia in middle-cerebral artery territory. The platelets subsequently increased by near 30%. The diagnosis of heparin-induced thrombocytopenia was finally confirmed a few days later by detection of antiplatelet-factor 4 antibodies associated with a positive platelet aggregation test for unfractionated heparin. Heparin was replaced by sodium danaparoid. These measures did not change the unfavorable outcome and death of the patient. The increase in the platelet count after fortuitous clopidogrel introduction raises the question of the role of antiaggregant agents in association with anticoagulants for the treatment of type II heparin-induced thrombocytopenia.

[Analysis of the anatomical sites of 172 lower-limb venous thromboses occurring in a hormonal context in 996 young women; impact of the duplex-Doppler exploration]. / Analyse de la distribution anatomique de 172 thromboses veineuses des membres inférieurs chez 996 jeunes femmes en contexte hormonal. Impact sur l'exploration écho-Doppler.

AIM: To analyze localizations of duplex ultrasonography-diagnosed lower-limb venous thrombosis in young women in hormonal periods in order to optimize the ultrasound exploration. PATIENTS AND METHODS: From 42,018 standardized ultrasonography report forms, incremented in a database (January 2001 - July 2013), those performed for a first diagnosis of venous thrombosis in women ≤ 45 years were selected (n = 996). Among those, diagnosed venous thrombosis (n = 172) were classified into three groups: oral contraception (n = 74), pregnancy (n = 39) and post-partum period (n = 59). Clinical symptoms and thrombosis distribution were analyzed. RESULTS: In the contraception group, pulmonary symptoms at presentation were much more frequent than in the obstetrical group: 69% vs 20% (P < 0.001). The thrombosis was limited to the iliac veins in 31% (23/74) and to the left internal iliac vein in six patients. During pregnancy, the thrombosis was limited to the iliac veins in 28% (11/39), and to the left internal iliac vein in two patients. In the post-partum period, superficial venous thromboses were found more frequently (37/59). Among the 22 deep venous thromboses, nine were limited to the proximal segment, including four in the vena cava coming from a right ovarian vein thrombosis. CONCLUSION: Duplex ultrasonography in young women taking oral contraception, as during pregnancy, must target iliac venous segments, especially on the left side, otherwise one thrombosis out of three may be missed; in the post-partum period, the inferior vena cava and superficial veins are to be explored too.

[Antiphospholipid syndrome and pregnancy: Obstetrical prognosis according to the type of APS]. / Syndrome des anticorps antiphospholipides et grossesse : pronostic obstétrical selon le type de SAPL.

OBJECTIVE: The objective of our study was to compare treatment-based obstetrical outcomes in women with either thrombotic or obstetrical antiphospholipid syndrome (APS). MATERIALS AND METHODS: This was a historical cohort study conducted between 1998 and 2009 in 23 patients who had a total of 83 pregnancies. The syndrome was diagnosed using the 2006 Sapporo criteria. RESULTS: Thirty-one of these 83 pregnancies were valid before the diagnosis was made. A live infant was born in 22% of them, the infant being small for gestational age in 26% of cases. The fetus died in utero in a further 26% of cases. Pregnancies were subdivided into 2 groups depending on whether the initial event leading to APS diagnosis was obstetrical or thrombotic. Treatment (aspirin and low molecular weight heparin) was based on this classification: the latter was given in a curative dose for thrombotic events, in a preventive dose for obstetrical events. No fetal loss was observed when treatment was administered according to the protocol. Nevertheless, 20% of the pregnancies with obstetrical APS were complicated by smallness for gestational age and only 38% of the infants were live births. More than 87% of the thrombotic forms treated were free of complications and led to birth of a living child. CONCLUSION: Appropriate treatment appears to improve the prognosis for pregnancies in patients with APS. These patients are nevertheless at increased risk of an obstetrical event and require close monitoring, especially in obstetrical manifestations, which appear to have a poorer prognosis. Multidisciplinary follow-up by an experienced team is essential.

Macrophagic myofasciitis associated with inclusion body myositis: a report of three cases.

We describe three patients with macrophagic myofasciitis and inclusion body myositis. All patients fulfilled diagnostic criteria for inclusion body myositis and myopathologic criteria for macrophagic myofasciitis. In the three cases macrophagic myofasciitis complicated the evolution of a known and painless inclusion body myositis and was diagnosed in a repeated deltoid biopsy because of the appearance of myalgia during the course of inclusion body myositis in all cases. The unexpected appearance of myalgia during the course of painless inclusion body myositis must arouse the suspicion of an association of another inflammatory muscle disease, macrophagic myofasciitis.

Necrotizing granulomata of the aortic valve in Wegener's disease.

Wegener's disease is an inflammatory disease of unknown etiology, characterized by a granulomatous-necrotizing general vasculitis. Cardiac involvement in the form of aortic pathology is not frequent. We report a case of Wegener's granulomatosis which required prosthetic aortic valve replacement for aortic valve insufficiency. Microscopic examination of the valve demonstrated histopathology typical of Wegener's disease.

[Orthotopic liver transplantation for metastases of bronchial carcinoid tumor]. / Transplantation orthotopique hépatique pour métastases d'une tumeur carcinoïde bronchique.

We report the case of a 42 year old man in whom orthotopic liver transplantation was performed successfully for unresectable hepatic metastases of a bronchial carcinoid tumor. Prior to transplantation, somatostatin therapy, pulmonary lobectomy, and systemic chemotherapy (streptozotocin and fluorouracil) were performed. After 9 months there were no signs of clinical or biological recurrence. Orthotopic liver transplantation might be indicated for unresectable and limited liver metastases of neuroendocrine tumor.

[Coronary revascularization provides confirmation of coronary and aortic giant-cell vasculitis]. / Revascularisation coronarienne apportant la confirmation d'une vascularite giganto-cellulaire coronarienne et aortique.

The present report describes a 58-year-old woman who had unstable angina pectoris 28 months after the end of corticosteroid treatment prescribed for biopsy-proven temporal arteritis. Coronary angiogram disclosed critical left main coronary artery stenosis. Despite a 3-week corticosteroid regimen no improvement was obtained and an aortocoronary bypass was performed. Histological examination of the affected artery showed vasculitis. Corticosteroid treatment was continued. Six months later, symptoms had not recurred and the coronary bypass graft was permeable. The stress test was negative fifteen months after surgery and the patient remained clinically well thirty months later. For any patient with current or previous temporal arteritis, any cardiovascular manifestation might be a new episode of giant-cell arteritis.

[Prevalence of duplex ultrasonography detectable venous thrombosis in patients with suspected or acute pulmonary embolism]. / Prévalence de la thrombose veineuse diagnostiquée par échographie-doppler des membres inférieurs dans la suspicion d'embolie pulmonaire et dans l'embolie pulmonaire confirmée.

OBJECTIVES: Duplex ultrasonography performance in detecting embolic foci has not been proven satisfactory compared with phlebography or autopsic findings. In case of suspected pulmonary embolism, the embolic focus is only discovered in 11 to 18% of the cases compared with more than 30% with phlebography. For overt acute pulmonary embolism, the discovery rate is in the 30 to 45% range versus 70 to 80% with phlebography or autopsy findings. This discrepancy might result from the fact that duplex ultrasonographic explorations are generally limited to the deep collectors at the cruropopliteal level. The purpose of this study was to assess the prevalence of duplex ultrasonography detected venous thrombosis in patients with suspected or acute pulmonary embolism when the exploration includes the entire venous system from the inferior vena cava to the ankles and examines not only the deep collectors but also the muscle and superficial networks. MATERIAL AND METHODS: This study included all patients with suspected pulmonary embolism referred to the emergency unit from January 1, 1995 through December 31, 1998. The patients' hospital files were used to determine the suspected pulmonary embolism population. The acute pulmonary embolism population was defined as the patients whose files contained documented proof of pulmonary embolism (highly probable ventilation/perfusion pulmonary scintigraphy, positive pulmonary angiography, positive proximal angioscan). Thrombosis of the deep venous collectors with or without associated superficial or muscular localization was classed as "deep venous thrombi" and superficial or muscular thrombosis without involvement of the deep collectors was classed as "other venous thrombi". Subpopliteal thrombosis was classed as distal and popliteal or suprapopliteal thrombosis as proximal. RESULTS: The suspected pulmonary embolism group included 352 patients, 118 men and 234 women aged 67.6 +/- 15.4 and 70.8 +/- 20.0 years respectively (m +/- SD). The acute pulmonary embolism group included 60 patients, 17 men and 43 women aged 66.2 +/- 12.5 and 69.7 +/- 16.6 years respectively. Overall prevalence of duplex-ultrasound detected venous thrombosis was 30.4% (107/352) (95%CI: 25.6-35.2) in the suspected pulmonary embolism group and 80% (48/60) (95%CI: 69.9-90.1) in the acute pulmonary embolism group. Deep venous thrombi reaching the collectors and proximal thrombi predominated. Prevalence of "other venous thrombi" and distal venous thrombi were 6.5% (23/352) and 11.4% (40/352) respectively in the suspected pulmonary embolism group and 15.0% (9/60) and 26.7% (16/60) in the acute pulmonary embolism group. The frequency of asymptomatic venous thrombosis of the lower limbs, irrespective of the localization, was 42.1% (45/107) in the suspected pulmonary embolism group and 52.1% (25/48) in the acute pulmonary embolism group. CONCLUSIONS: The prevalence of duplex-ultrasonography detected venous thrombosis in patients with suspected or proven pulmonary embolism found in this series was equivalent to the rates reported in phlebography and autopsy series. The prevalence was higher than usually reported for duplex-ultrasonography studies limited to the cruro-popliteal level. The difference came from the "other venous thrombi" and "distal deep venous thrombi" discovered by exploring the superficial and muscular networks and the calves. This study demonstrates the contribution of duplex-ultrasonography to the diagnostic strategy for pulmonary embolism.
