General practitioners and palliative care practices: a better knowledge of specific services is still needed.

BACKGROUND: France allows deep sedation for pain relief, but not for euthanasia. In anticipation of an increase in home-based palliative care, the role of general practitioners is central to the design of outpatient palliative care services. This study aimed to describe the knowledge, attitudes, and practices of general practitioners in mainland France regarding palliative and end of life care. METHODS: This was a national descriptive cross-sectional study within the Sentinelles network. Self-report questionnaires were distributed to general practitioners between November 2020 and November 2021. A descriptive analysis was carried out. RESULTS: Out of the 123 participating general practitioners, 84% had received academic training in palliative care (n = 104). While a significant majority (69%) expressed comfort in pain management, only a quarter (25%) declared that they were competent at indicating deep and continuous sedation for pain relief. Awareness of outpatient palliative care facilities close to their place of practice such as hospitalization at home was over 97% (n = 117/120). Awareness of hospital facilities, including identified palliative care beds on hospital wards and palliative care units, was lower (75% (n = 59/79) and 86% (n = 86/100), respectively). CONCLUSIONS: Our results suggest that French general practitioners are reasonably aware of palliative care resources available. However, there is room for improvement, particularly in understanding hospital-based facilities. Furthermore, a quarter of the general practitioners expressed discomfort with deep and continuous sedation for pain relief, highlighting the need for increased training in this specific aspect of palliative and end of life care.

[Anaphylaxis: an update]. / Anaphylaxie : mise à jour.

Anaphylaxis is the most severe form of acute systemic allergic reaction and can be fatal in the absence of adequate treatment with adrenaline. We propose to review the different mechanisms underlying anaphylaxis, as well as the diagnostic criteria and its management regarding the 2020 guidelines of the World Allergy Organization (WAO).

L'anaphylaxie est la forme la plus sévère de réaction allergique aiguë systémique et peut être fatale en l'absence d'un traitement adéquat par adrénaline. Nous proposons de revoir les différents mécanismes sous-jacents à l'anaphylaxie, ses critères diagnostiques ainsi que sa prise en charge à la lumière des directives 2020 de la World Allergy Organization (WAO).

ScapuloThoracic Arthrodesis for Facio-Scapulo-Humeral Dystrophy: Outcomes at mean 7.3 years [3.5-13] follow-up. CT measurement of the fixation position of the arthrodesis and radioclinical correlations.

INTRODUCTION: Scapulothoracic arthrodesis may be proposed to patients having facio-scapulohumeral dystrophy to achieve gains in shoulder motion and pain relief. This study aimed to assess shoulder motion, pain and functional scores at last follow-up and to present a method of computed tomography measurements of the position of the scapulothoracic arthrodesis and study their correlations with shoulder motion. PATIENTS AND METHODS: Seven patients (11 arthrodesis) were included. Shoulder motion, pain, respiratory function and deltoid strength were compared with preoperative values and Constant, Brooke and Vignos scores were assessed at last follow-up. The elevation/depression and upward/downward position of the scapula were measured by performing postoperative 3D CT reconstruction. The protraction/retraction position was measured with 2D CT reconstructions on axial view. Correlations between these measurements and shoulder flexion and abduction were analysed. All complications were searched. RESULTS: We found a significant improvement in mean VAS (from 3±2 to 1±1, p=0,008) shoulder flexion (64°± 11 to 113°±20, p=0,003) and abduction (from 63°±9 to 92°±13°, p=0,004). Postoperative external rotation wasn't significantly different (from 49°±19 to 43°±10, p=0,112) and on internal rotation, the hand reached on average the 9th thoracic vertebra (S1-T2). Scapulothoracic arthrodesis was mainly positioned in regard to the 1st and the 6th rib. The mean protraction/retraction position was 38,5°±8° and the mean scapular upward/downward rotation position was 92°±15°. No correlations were found between the scapular position and shoulder flexion and abduction. CONCLUSIONS: Scapulothoracic arthrodesis for facioscapulohumeral dystrophy improved pain, shoulder flexion and abduction and provided good functional outcomes at 3,5 to 13 years of follow up. A method of CT assessment of the position of the arthrodesis is presented to analyse precisely the position of the scapula but no correlations with shoulder motions were found. Preoperative evaluation of deltoid function and scapular winging seemed to be the most important predictors of shoulder motions gains after this procedure.

[Feelings of cancer patients in exclusive palliative care: Towards a general practitioner, oncologist pairing?] / Ressenti des patients atteints de cancer en soins palliatifs exclusifs: vers un binôme médecin généraliste, cancérologue?

INTRODUCTION: In palliative care, cancer patients' thoughts about support given by their general practitioner are poorly described in the literature. General practitioners are involved in the management of cancer patients in palliative care, but when contact with the oncologist become less frequent, the place of the patient's different doctors becomes difficult to define. The objective of our work is to analyze the patient's perception of the place and role of the general practitioner. METHODS: Qualitative study by individual semi-directed interviews, with voluntary patients with solid cancer in palliative care. Patients were selected by palliative care physicians. A thematic analysis was performed on the basis of the patients' verbatim transcripts. RESULTS: Seventeen patients were interviewed and four main themes were highlighted: a perception of abandonment, a resignation to call the general practitioner, an omnipresence of the oncologist who seems not to leave the place to the general practitioner and a search for global support. The general practitioner did not appear to be empathetic nor supportive enough and was not available enough. DISCUSSION: Patients are looking for empathy and for their doctors to listen. Our work shows a certain disappointment of the patients regarding the place and role of their general practitioner. This disappointment reflects the insufficient coordination between hospital and community care setting. While the early integration of palliative care is becoming a standard of care, the patients' testimony commits us to improve the articulation between the oncologist and the general practitioner.

Impact of introducing extremity cone-beam CT in an emergency radiology department: A population-based study.

BACKGROUND: Musculoskeletal cone-beam CT (CBCT) recently appeared on the market, with image quality comparable to that of high-resolution CT. It was previously implemented mainly in craniofacial surgery and in orthopedic limb surgery for weight-bearing imaging, but without large-scale assessment in emergency settings. We therefore conducted a retrospective comparative study in an emergency radiology department: 1) to assess whether introduction of CBCT dedicated to extremity traumatology reduced radiation dose delivered to the patient undergoing cross-sectional imaging, 2) to assess whether it increased turnover, and 3) to study the feasibility and practical consequences. Study hypothesis Introducing CBCT dedicated to traumatology in an emergency radiology department reduces radiation dose related to cross-sectional imaging in extremity trauma. PATIENTS AND METHODS: Two periods were distinguished: in May-November 2016, the only cross-sectional imaging available in our emergency radiology department was multi-detector CT (MDCT); in May-November 2017, both MDCT and CBCT were available. Thus, the population in period 1 (n=165) had undergone only MDCT extremity imaging, while patients in period 2 underwent either CBCT (n=139) or MDCT (n=85). Study parameters notably included dose-length product (DLP) and length of patient stay in the radiology department (turnover). RESULTS: Mean DLP was significantly reduced with the introduction of CBCT: 210.3±133.6 mGy.cm (range, 20-595) in period 1, versus 138.4±92.7 mGy.cm (range, 32-623) in period 2 (p<0.0001). Taking both periods together, mean DLP was 50.7% lower with CBCT (n=139) than MDCT (n=249): respectively, 101.6±14.9 mGy.cm (range, 50.6-126.9) versus 206.5±131.8 mGy.cm (range, 20-623) (p<0.0001). Turnover accelerated with the introduction of CBCT, with mean stay of 84.9minutes in period 1 versus 72.1minutes in period 2 (p=0.011). In period 2, turnover was 23.6% faster with CBCT than MDCT: respectively, 64.9minutes versus 85.0minutes (p=0.0004). DISCUSSION: Introducing CBCT dedicated to the extremities in an emergency radiology department was feasible. It reduced overall radiation dose and accelerated turnover. LEVEL OF EVIDENCE: III; comparative case-control study.

The advantages of cone-beam computerised tomography (CT) in pain management following total knee arthroplasty, in comparison with conventional multi-detector CT.

BACKGROUND: Revision of total knee arthroplasty (TKA) requires preoperative assessment to identify the causes of failure. Multidetector computerised tomography (MDCT) is a commonly used imaging technique, but is sensitive to certain artifacts, such as metal implants, limiting its use. Cone-beam CT (CBCT) is a new technique dedicated to musculoskeletal imaging that is less sensitive to artifacts and could be utilised in knee implantation surgery. CBCT has not yet been validated for this indication, and we therefore undertook a retrospective assessment of MDCT versus CBCT, comparing: 1) image quality; 2) reproducibility of angle measurements; 3) effectiveness in screening for periprosthetic radiolucency and implant loosening; and 4) radiation dose. HYPOTHESIS: This study hypothesised that CBCT provides better image quality, angle measurement reproducibility, and screening for radiolucency and implant loosening at lower doses of radiation than MDCT. PATIENTS AND METHOD: Between October 2017 and March 2018, 28 patients, with a mean age of 61±11.6 years [range, 45-85 years] underwent both MDCT and CBCT for pain following TKA. Two radiologists performed angle measurements on both devices: patellofemoral tilt (PFT), rotation angle of the femoral component (RAFC) and rotation angle of the tibial component (RATC). They also screened for pathological radiolucency and/or implant loosening, and assessed image quality at the various bone/implant interfaces. The mean CT dose index per examination was recorded. RESULTS: Intraclass correlation coefficients for angles and radiolucency screening on MDCT and on CBCT were respectively good (0.73) and excellent (0.82) for PFT, borderline (0.28) and moderate (0.44) for RAFC, excellent (0.82) and excellent (0.96) for RATC, and moderate (0.45) and excellent (0.84) for radiolucency screening. The inter-observer kappa correlation coefficients for diagnosis of implant loosening and image quality assessment for MDCT and CBCT were respectively moderate (0.45) and excellent (0.93) for tibial loosening and low (0.19) and borderline (0.38) for femoral loosening. The mean image quality at the various interfaces for MDCT and CBCT was respectively 2.2/3 and 2.75/3 at the tibia/tibial implant interface, 1/3 and 2.3/3 at the trochlear region/femoral implant interface, 0.9/3 and 2/3 at the femoral condyle/femoral implant interface, and 1.25/3 and 2.1/3 at the patella/patellar medallion interface. The mean CT dose index was significantly lower, by a factor of 1.24, on CBCT (4.138 mGy) than MDCT (5.125 mGy) (p<00396). CONCLUSION: The results of the present study revealed added value for CBCT in the etiological work-up for pain following a TKA. It was reliable and reproducible for the rotation measurement and diagnosis of implant loosening, due to enhanced image quality despite a lower radiation dose than conventional MDCT. LEVEL OF EVIDENCE: III; retrospective comparative study.

Bone and joint complications in patients with hereditary hemochromatosis: a cross-sectional study of 93 patients.

BACKGROUND: The aim of this study was to determine the frequency and characteristics of bone and joint complications, specifically bone fragility, joint replacement surgery, and arthropathy, in hereditary hemochromatosis (HH) and related factors. METHODS: This study was a cross-sectional observational study of 93 patients with HH. Radiographs of the hands, wrists, knees, and ankles were scored for joint space narrowing, erosions and cysts, osteophytes, and chondrocalcinosis. Prevalent (vertebral and non-vertebral) fragility fractures were recorded and bone mineral density (BMD) was systematically evaluated by dual energy X-ray absorptiometry. Bone fragility was defined as (i) a T-score ⩽ -2.5 at any site with or without a prevalent fragility fracture, or (ii) a T-score between -1.0 and -2.5 at any site and a prevalent fragility fracture. RESULTS: The mean age of the patients was 60.0 (11.2) years, and 58.0% of them were men. The frequency of radiographic MCP2-3 arthropathy was 37.6% (95% CI 0.28-0.48). Radiographic MCP2-3 arthropathy was independently associated with older age [OR 1.17 (1.09-1.26) per year, p < 0.0001], male sex [OR 3.89 (1.17-12.97), p = 0.027] and C282Y+/+ genotype [OR 4.78 (1.46-15.68), p = 0.010]. The frequency of joint replacement surgery was 12.9% (95% CI 0.07-0.21). The frequency of bone fragility was 20.4% (95% CI 0.13-0.30). Bone fragility was independently associated with hepatic cirrhosis [OR 8.20 (1.74-38.68), p = 0.008]. DISCUSSION: Radiographic MCP2-3 arthropathy was found to occur in 37.6% of patients with HH. The association observed between this form of arthropathy and C282Y homozygosity, male sex, and older age suggests that demographic characteristics and genetic background are likely to be major determinants of this joint disorder and play a more important role than severity of iron overload. Bone fragility was observed in a fifth of the patients with HH, independently of genetic background and severity of iron overload, and was strongly associated with hepatic cirrhosis. CONCLUSION: Future investigations should focus on pathogenesis and early identification of patients at risk of developing bone and joint complications secondary to HH.

Quality of web-based information on bipolar disorder.

OBJECTIVE: To evaluate web-based information on bipolar disorder and to assess particular content quality indicators. METHODS: Two keywords, "bipolar disorder" and "manic depressive illness" were entered into popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability and content quality. "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. RESULTS: Of the 80 websites identified, 34 were included. Based on outcome measures, the content quality of the sites turned-out to be good. Content quality of web sites dealing with bipolar disorder is significantly explained by readability, accountability and interactivity as well as a global score. CONCLUSIONS: The overall content quality of the studied bipolar disorder websites is good.

Bronchoscopy with the Vision Sciences BF100 disposable-sheath device: French experience after 328 procedures.

BACKGROUND: In spite of adhesion to recommended disinfection procedures, the transmission of infections by bronchoscopes is a permanent problem. OBJECTIVE: The new device may prevent nosocomial infections because it consists of two parts: a specific bronchoscope Vision Sciences BF100 and a single-use protective sheath for each procedure. The aim of this paper is to report our practice and the difficulties encountered when using this system. METHODS: We report our experience from 1997 to 2002 after 328 elective and emergency endoscopic procedures with the BF100 device. In a retrospective study, we describe the population and the incidents during procedure. We discuss the impact of the use of BF100 on the cost of bronchoscopies. RESULTS: The major constraint is the care required in assembling the optical device and disposable sheath. The intrinsic qualities of the optics are confirmed; any sample may be taken although image quality and suction capacity are inferior to videoscopes. Maneuverability is inferior to videoscopes, but improves with a short experience. In addition, this device is expensive. CONCLUSIONS: The technical performances of the BF100 device are inferior to those of videoscopes but the concept of sterile single-use sheaths is able to prevent the nosocomial infections related to bronchoscopes. Because of the cost, examination with the BF100 should be reserved to patients with proved or suspected infection (multiresistant bacteria, tuberculosis, hepatitis C and B virus, HIV, prions) and immunosuppression (hematologic diseases).
