Résumé. La luxation d’un doigt est une pathologie souvent rencontrée dans les centres d’urgence. L’exemple du cas suivant permet un rappel sur sa prise en charge et les situations dans lesquelles le patient doit être référé au spécialiste.

Contexte : Le raisonnement clinique est un processus complexe qui est au cœur de la pratique médicale. Les médecins généralistes qui suivent des patients souffrant de multimorbidité doivent allier plusieurs rôles dans ce type de suivi. Les métaphores sont un outil de langage qui donne potentiellement accès au raisonnement clinique sous-jacent à cette prise en charge. Objectif : Analyser les métaphores évoquées par les médecins généralistes pour mieux comprendre leur raisonnement clinique. Méthodes : Neuf médecins généralistes (5 femmes et 4 hommes) âgés entre 29 et 57 ans ont participé à l’étude. Des entretiens non directifs ont été menés, transcrits et analysés selon le cadre de l’analyse systématique des métaphores de Schmitt. Résultats : Sept thèmes métaphoriques récurrents ont émergé. Dans ces thèmes métaphoriques, les médecins généralistes décrivent leurs processus de raisonnement clinique face à la multimorbidité comme (1) une construction, (2) un sudoku ou un puzzle, (3) une Odyssée, (4) une histoire avec quelqu’un, (5) une course d’orientation, (6) regarder un tableau et (7) jouer une mélodie. Conclusion : Les métaphores peuvent faire ressortir la complexité du processus de raisonnement clinique des médecins généralistes dans la prise en charge au long cours de patients souffrant de multimorbidité et contribuer à mieux le comprendre et l’expliciter.

Background The so-called ‘mycobiome’ has progressively acquired interest and increased the complexity of our understanding of the human gut microbiota. Several questions are arising concerning the role of fungi (and in particular of Candida albicans), the so-called ‘mycobiome’, that has been neglected for a long time and only recently gained interest within the scientific community. There is no consensus on mycobiome normobiosis because of its instability and variability. This review aims to raise awareness about this interesting topic and provide a framework to guide physicians faced with such questions. Objectives To summarize current knowledge and discuss current and potential implications of the mycobiome in clinical practice. Sources We performed a review of the existing literature in Medline Pubmed. Content This review identifies several studies showing associations between specific mycobiome profiles and health. Fungi represent a significant biomass within the microbiota and several factors, such as diet, sex, age, co-morbidities, medications, immune status and inter-kingdom interactions, can influence its structure and population. The human gut mycobiota is indeed a key factor for several physiological processes (e.g. training of the immune system against infections) and pathological processes (e.g. immunological/inflammatory disorders, inflammatory bowel diseases, metabolic syndromes). Moreover, the mycobiome (and C. albicans in particular) could influence an even broader spectrum of conditions such as psychiatric diseases (depression, schizophrenia, bipolar disorder) or chronic viral infections (human immunodeficiency virus, hepatitis B virus); moreover, it could be implicated in tumorigenesis. Implications Candida albicans is a well-known opportunistic pathogen and a major component of the mycobiome but its role in the gastrointestinal tract is still poorly understood. From a potential screening biomarker to a key factor for several pathological processes, its presence could influence or even modify our clinical practice.

Caregiver-patient communication is a central element of the therapeutic relationship and a powerful placebo. While poorly adapted communication can have harmful effects, adequate communication offers many benefits for the patient and the caregiver. Therapeutic communication (TC), a set of strategies inspired by clinical hypnosis, is easy to learn and apply. In addition to reinforcing an empathetic attitude, TC appears to be effective in various clinical situations, particularly for its effects on pain and anxiety. In order to better understand the interest of CT in internal medicine, we have conducted a literature review on its efficacy during different medical procedures.La communication soignant-e/soigné-e est un élément central de la relation thérapeutique et un puissant placebo dont il serait dommage de se priver. Mal adaptée, elle peut avoir des effets néfastes, efficace, elle offre de nombreux bénéfices pour les patient-e-s et soignant-e-s. La communication thérapeutique (CT), un ensemble de stratégies inspirées de l’hypnose clinique, est facile à apprendre et à appliquer. En plus de renforcer une attitude empathique, la CT semble efficace dans diverses situations cliniques, notamment pour ses effets sur la douleur et l’anxiété. Dans le but de mieux comprendre l’intérêt de la CT en médecine interne, nous avons effectué une revue de littérature démontrant son utilisation lors de gestes techniques auxquels les patient-e-s sont fréquemment confronté-e-s.

Introduction GP’s clinical reasoning processes in the context of patients suffering from multimorbidity are often a process which remains implicit. Therefore, the goal of this case study analysis is to gain a better understanding of the processes at play in the management of patients suffering from multimorbidity. Methods A case study analysis, using a qualitative thematic analysis was conducted. This case follows a 54-year-old woman who has been under the care of her GP for almost 10 years and suffers from a number of chronic conditions. The clinical reasoning of an experienced GP who can explicitly unfold his processes was chosen for this case analysis. Results Four main themes emerged from this case analysis: The different roles that GPs have to manage; the GP’s cognitive flexibility and continual adaptation of their clinical reasoning processes, the patient’s empowerment, and the challenges related to the collaboration with specialists and healthcare professionals. Conclusion This could help GPs gain a clearer understanding of their clinical reasoning processes and motivate them to communicate their findings with others during clinical supervision or teaching. Furthermore, this may emphasize the importance of valuing the role of the primary care physician in the management of multimorbid patients.

Persistent symptoms of SARS-CoV-2 are prevalent weeks to months following the infection. To date, it is difficult to disentangle the direct from the indirect effects of SARS-CoV-2, including lockdown, social, and economic factors.The study aims to characterize the prevalence of symptoms, functional capacity, and quality of life at 12 months in outpatient symptomatic individuals tested positive for SARS-CoV-2 compared to individuals tested negative.From 23 April to 27 July 2021, outpatient symptomatic individuals tested for SARS-CoV-2 at the Geneva University Hospitals were followed up 12 months after their test date.At 12 months, out of the 1447 participants (mean age 45.2 years, 61.2% women), 33.4% reported residual mild to moderate symptoms following SARS-CoV-2 infection compared to 6.5% in the control group. Symptoms included fatigue (16% vs. 3.1%), dyspnea (8.9% vs. 1.1%), headache (9.8% vs. 1.7%), insomnia (8.9% vs. 2.7%), and difficulty concentrating (7.4% vs. 2.5%). When compared to the control group, 30.5% of SARS-CoV-2 positive individuals reported functional impairment at 12 months versus 6.6%. SARS-CoV-2 infection was associated with the persistence of symptoms (adjusted odds ratio [aOR] 4.1; 2.60-6.83) and functional impairment (aOR 3.54; 2.16-5.80) overall, and in subgroups of women, men, individuals younger than 40 years, those between 40-59 years, and in individuals with no past medical or psychiatric history.SARS-CoV-2 infection leads to persistent symptoms over several months, including in young healthy individuals, in addition to the pandemic effects, and potentially more than other common respiratory infections. Symptoms impact functional capacity up to 12 months post infection.

Neuropsychological deficits and brain damage following SARS-CoV-2 infection are not well understood. 110 patients, with either severe, moderate or mild disease in the acute phase underwent neuropsychological and olfactory tests, as well as completed psychiatric and respiratory questionnaires at 223 ± 42 days post-infection. Additionally, a subgroup of 50 patients underwent functional magnetic resonance imaging. Patients in the severe group displayed poorer verbal episodic memory performances, and moderate patients had reduced mental flexibility. Neuroimaging revealed patterns of hypo and hyper functional connectivity in severe patients, while only hyperconnectivity patterns were observed for moderate. The default mode, somatosensory, dorsal attention and cerebellar networks were implicated. Partial least squares correlations analysis confirmed specific association between memory performances and brain functional connectivity. The severity of the infection in the acute phase is a predictor of neuropsychological post-COVID syndrome. SARS-CoV-2 infection causes long-term memory and executive dysfunctions, related to largescale functional brain connectivity alterations.

ObjectivesThe aim of this study was to determine the prevalence and forms of gender discrimination and sexual harassment experienced by medical students and physicians in French-speaking part of Switzerland.Design and settingWe conducted an online survey using a questionnaire of 9 multiple-choice and 2 open questions between 24 January 2019 and 24 February 2019. Our target population was medical students and physicians working at hospitals and general practitioners from the French-speaking part of Switzerland. The online survey was sent via social media platforms and direct emails. We compared answers between male-determined and female-determined respondents using either χ2 or Fisher’s exact tests.ResultsAmong 1071 responders, a total of 893 were included (625 females, 264 males, 4 non-binary and 1 non-binary and male). 178 were excluded because they did not mention their working place or were working only outside Switzerland. Because of the small number of non-binary participants, they were not contemplated in further statistical analysis. Of 889 participants left, 199 (31.8%) women and 18 (6.8%) men reported having personally experienced gender discrimination, in terms of sexism, difficulties in career development and psychological pressure. Among women, senior attendings were the most affected (55.2%), followed by residents (44.1%) and junior attendings (41.1%). Sexual harassment was equally observed among women (19.0%) and men (16.7%). Compared with men (47.0%), women (61.4%) expressed the need to promote equality and inclusivity in medicine more frequently (pConclusionsGender discrimination in medicine in French-speaking Switzerland affects one-third of women, in particular, those working in hospital settings and senior positions.

Cognitive biases are systematic cognitive distortions, which can affect clinical reasoning. The aim of this study was to unravel the most common cognitive biases encountered in in the peculiar context of the COVID-19 pandemic. Case study research design. Primary care. Single centre (Division of General Internal Medicine, University Hospitals of Geneva, Geneva, Switzerland). A short survey was sent to all primary care providers (N = 169) taking care of hospitalised adult patients with COVID-19. Participants were asked to describe cases in which they felt that their clinical reasoning was “disrupted” because of the pandemic context. Seven case were sufficiently complete to be analysed. A qualitative analysis of the clinical cases was performed and a bias grid encompassing 17 well-known biases created. The clinical cases were analyzed to assess for the likelihood (highly likely, plausible, not likely) of the different biases for each case. The most common biases were: “anchoring bias”, “confirmation bias”, “availability bias”, and “cognitive dissonance”. The pandemic context is a breeding ground for the emergence of cognitive biases, which can influence clinical reasoning and lead to errors. Awareness of these cognitive mechanisms could potentially reduce biases and improve clinical reasoning. Moreover, the analysis of cognitive biases can offer an insight on the functioning of the clinical reasoning process in the midst of the pandemic crisis.

Lack of awareness of cognitive impairment (i.e. anosognosia) could be a key factor for distinguishing between neuropsychological post-COVID-19 condition phenotypes. In this context, the 2-fold aim of the present study was to (i) establish the prevalence of anosognosia for memory impairment, according to the severity of the infection in the acute phase and (ii) determine whether anosognosic patients with post-COVID syndrome have a different cognitive and psychiatric profile from nosognosic patients, with associated differences in brain functional connectivity. A battery of neuropsychological, psychiatric, olfactory, dyspnoea, fatigue and quality-of-life tests was administered 227.07 ± 42.69 days post-SARS-CoV-2 infection to 102 patients (mean age: 56.35 years, 65 men, no history of neurological, psychiatric, neuro-oncological or neurodevelopmental disorder prior to infection) who had experienced either a mild (not hospitalized; n = 45), moderate (conventional hospitalization; n = 34) or severe (hospitalization with intensive care unit stay and mechanical ventilation; n = 23) presentation in the acute phase. Patients were first divided into two groups according to the presence or absence of anosognosia for memory deficits (26 anosognosic patients and 76 nosognosic patients). Of these, 49 patients underwent an MRI. Structural images were visually analysed, and statistical intergroup analyses were then performed on behavioural and functional connectivity measures. Only 15.6% of patients who presented mild disease displayed anosognosia for memory dysfunction, compared with 32.4% of patients with moderate presentation and 34.8% of patients with severe disease. Compared with nosognosic patients, those with anosognosia for memory dysfunction performed significantly more poorly on objective cognitive and olfactory measures. By contrast, they gave significantly more positive subjective assessments of their quality of life, psychiatric status and fatigue. Interestingly, the proportion of patients exhibiting a lack of consciousness of olfactory deficits was significantly higher in the anosognosic group. Functional connectivity analyses revealed a significant decrease in connectivity, in the anosognosic group as compared with the nosognosic group, within and between the following networks: the left default mode, the bilateral somatosensory motor, the right executive control, the right salient ventral attention and the bilateral dorsal attention networks, as well as the right Lobules IV and V of the cerebellum. Lack of awareness of cognitive disorders and, to a broader extent, impairment of the self-monitoring brain system, may be a key factor for distinguishing between the clinical phenotypes of post-COVID syndrome with neuropsychological deficits.

Lung ultrasonography (LUS) is an accurate method of estimating lung congestion but there is ongoing debate on the optimal number of scanning points. The aim of the present study was to compare the reproducibility (i.e. interobserver agreement) and the feasibility (i.e. time consumption) of the two most practiced protocols in patients hospitalized for acute heart failure (AHF). This prospective trial compared 8- and 28-point LUS protocols. Both were performed by an expert–novice pair of sonographers at admission and after 4 to 6 days on patients admitted for AHF. A structured bio-clinical evaluation was simultaneously carried out by the treating physician. The primary outcome was expert-novice interobserver agreement estimated by kappa statistics. Secondary outcomes included time spent on image acquisition and interpretation. During the study period, 43 patients underwent a total of 319 LUS exams. Expert–novice interobserver agreement was moderate at admission and substantial at follow-up for 8-point protocol (weighted kappa of 0.54 and 0.62, respectively) with no significant difference for 28-point protocol (weighted kappa of 0.51 and 0.41; P value for comparison 0.74 at admission and 0.13 at follow-up). The 8-point protocol required significantly less time for image acquisition at admission (mean time difference − 3.6 min for experts, − 5.1 min for novices) and interpretation (− 6.0 min for experts and − 6.3 min for novices; P value

Background Leptospirosis is an underdiagnosed bacterial infection with nonspecific symptoms, hence, a diagnostic challenge. Identifying a case of leptospirosis in Switzerland is uncommon. Although kidney complications are frequent in severe forms, including tubular dysfunction, observing this complication is rare in our country. We report the case of a patient with leptospirosis and kidney dysfunction, which was notable for proximal tubulopathy. This case report describes the diagnosis and management of this patient’s tubular dysfunction. Case presentation A 34-year-old Caucasian male known for alcohol and drug abuse presented to our emergency department suffering from severe pain in the lower limbs, jaundice, and fever with flu-like symptoms. Physical examination was not contributory. Blood tests showed cytopenia, elevated inflammatory markers, acute kidney injury, and altered liver function tests with predominant cholestasis. Urinalysis showed proteinuria and significant glycosuria without concomitant hyperglycemia. Leptospirosis was suspected and confirmed by both positive serum polymerase chain reaction and elevated immunoglobulin M for Leptospira interrogans. The patient was treated with intravenous amoxicillin–clavulanate and doxycycline for 7 days. After antibiotic treatment, symptoms disappeared, and kidney dysfunction completely resolved. Conclusion Our case focuses on the description of leptospirosis-related acute kidney injury with proximal tubular dysfunction, which is a rare finding in Switzerland.

The biopsychosocial complexity of chronic pain requires a multimodal approach of which hypnosis is one. Its effectiveness is increasingly proven by studies using functional neuroimaging, as well as clinical studies in various etiologies of chronic pain. The goal of hypnosis is to restore the patient to an active role where, during the sessions, he will discover his creative capacities allowing him to temporarily modify or even significantly reduce painful sensations. Regular practice of self-hypnosis amplifies and anchors these changes. Gradually, hypnosis allows patients to regain both physical and mental mobility.La complexité biopsychosociale des douleurs chroniques impose une approche multimodale dont l’hypnose fait partie. Son efficacité est de plus en plus prouvée par des études utilisant la neuro-imagerie fonctionnelle, ainsi que des études cliniques dans diverses étiologies de douleurs chroniques. Le but de l’hypnose est de redonner au patient un rôle actif où, au cours des séances, il découvrira ses capacités créatrices lui permettant de modifier, voire de nettement réduire temporairement les sensations douloureuses. La pratique régulière de l’autohypnose amplifie et ancre ces modifications. Progressivement, l’hypnose permet aux patients de retrouver une mobilité tant physique que psychique.

Despite progress in primary and secondary prevention, pharmacological and device-based therapies, cardiovascular disease remains a leading cause of morbidity and mortality worldwide. The specifics of cardiac disorders being in the spotlight, less attention has been given to psychological health and its interdependent relation to cardiovascular disease. Psychological health issues can contribute to increase cardiovascular disease risk, and cardiovascular disease itself can promote development of mental health issues. Psychological health in patients with cardiovascular disease represents an underexplored opportunity for intervention, an endeavour that could be designed as behavioural cardiology, which would be synergistic with efforts aimed at primary and secondary prevention.Malgré les progrès réalisés en prévention primaire et secondaire ainsi qu’en termes de traitements pharmacologiques et de dispositifs médicaux, les pathologies cardiovasculaires restent la cause principale de morbidité et de mortalité à travers le monde. L’attention médicale portant particulièrement sur les pathologies cardiaques elles-mêmes, la santé mentale du patient peut être l’objet d’une attention insuffisante. Les souffrances psychiques contribuent à une augmentation du risque de pathologie cardiovasculaire et, réciproquement, une pathologie cardiovasculaire rend vulnérable et peut favoriser l’apparition d’un trouble psychique. La prise en charge globale du sujet cardiopathe, en particulier de son vécu intrapsychique, représente une opportunité d’intervention largement sous-exploitée. Cette discipline, nommons-la

Acute encephalopathy is one of the most frequent neurological complication in patients hospitalized for COVID-19. Electrolyte imbalance, drugs, and hypoxemia can all affect brain homeostasis, leading to acute cognitive dysfunction and direct implications of the SARS-CoV-2 are not completely understood. Neurological complications of SARS-CoV-2 infection are poorly understood: an inflammatory insult to the endothelium affecting the blood-brain barrier may explain the clinical presentation, but other hypotheses including direct viral damage or an immune-mediated reaction are also suggested. Among these various potential mechanisms, often combined, the controversy remains.L’encéphalopathie aiguë est l’une des principales complications neurologiques des patients hospitalisés pour un Covid-19. Si les complications électrolytiques, les différents traitements et l’hypoxémie ont un effet sur l’homéostasie cérébrale entraînant une perturbation de la cognition, les conséquences cérébrales directes ou indirectes du SARS-CoV-2 ne sont pas complètement élucidées. L’implication du virus entraînant une atteinte endothéliale des vaisseaux cérébraux pourrait participer à cette encéphalopathie, via une fragilisation de la barrière hémato-encéphalique et un passage facilité des cytokines pro-inflammatoires. L’atteinte virale directe ou la réaction autoimmune secondaire ont également été invoquées. Face aux multiples mécanismes physiopathologiques possibles pouvant expliquer cette encéphalopathie, le débat est ouvert.

ImportanceSerological assays detecting specific IgG antibodies generated against the Spike protein following Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection are being widely deployed in research studies and clinical practice. However, the duration and the effectiveness of the protection conferred by the immune response against future infection remains to be assessed in a large population.ObjectiveTo estimate the incidence of newly acquired SARS-CoV-2 infections in seropositive individuals from a population-based sample as compared to seronegative controls.DesignRetrospective longitudinal propensity-score matched cohort study.SettingA seroprevalence survey including a population-based representative sample of the population from the canton of Geneva (Switzerland) was conducted between April and June 2020, immediately after the first pandemic wave. Each individual included in the seroprevalence survey was linked to a state centralized registry compiling virologically confirmed SARS-CoV-2 infections since the beginning of the pandemic.ParticipantsParticipants aged twelve years old and over, who developed anti-spike IgG antibodies were matched one-to-two to seronegative controls, using a propensity-score including age, gender, immunodeficiency, body mass index, smoking status and education level.ExposureSARS-CoV-2 seropositivity.Main outcomes and measuresOur primary outcome was virologically confirmed SARS-CoV-2 infections which occurred from serological status assessment in April-June 2020 to the end of the second pandemic wave (January 2021). Additionally, incidence of infections, rate of testing and proportion of positive tests were analysed.ResultsAmong 8344 serosurvey participants, 498 seropositive individuals were selected and matched with 996 seronegative controls. After a mean follow-up of 35.6 (Standard Deviation, SD: 3.2) weeks, 7 out of 498 (1.4%) seropositive subjects had a positive SARS-CoV-2 test, of which 5 (1.0%) were considered as reinfections. By contrast, infection rate was significantly higher in seronegative individuals (15.5%, 154/996) during a similar mean follow-up of 34.7 (SD 3.2) weeks, corresponding to a 94% (95%CI 86% to 98%,PConclusions and relevanceSeroconversion after SARS-CoV-2 infection confers protection to successive viral contamination lasting at least 8 months. These findings could help global health authorities establishing priority for vaccine allocation.Key pointsQuestionDo SARS-CoV-2 antibodies confer protection against future infection?FindingsIn this retrospective matched cohort study nested in a representative sample of the general population of Geneva, Switzerland, we observed a 94% reduction in the hazard of being infected among participants with antibodies against SARS-CoV-2, when compared to seronegative controls, >8 months after initial serology assessment.MeaningSeroconversion to SARS-CoV-2 is associated with a large and sustained protection against reinfection.

BackgroundThere is growing awareness that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can include long-term neuropsychological deficits, even in its mild or moderate respiratory forms.MethodsStandardized neuropsychological, psychiatric, neurological and olfactory tests were administered to 45 patients (categorized according to the severity of their respiratory symptoms during the acute phase) 236.51 ± 22.54 days post-discharge following SARS-CoV-2 infection.ResultsDeficits were found in all the domains of cognition and the prevalence of psychiatric symptoms was also high in the three groups. The severe performed more poorly on long-term episodic memory and exhibited greater anosognosia. The moderate had poorer emotion recognition, which was positively correlated with persistent olfactory dysfunction. The mild were more stressed, anxious and depressed.ConclusionThe data support the hypothesis that the virus targets the central nervous system (and notably the limbic system), and support the notion of different neuropsychological phenotypes.
