RESUMEN

PURPOSE: Clinical reasoning and treatment challenges within the scope of general practice led to the development of an internal medicine assistance line provided by Nantes University Hospital. The primary outcome of this study was to describe callers' profile, their requests and answers provided. METHODS: A prospective, cross-sectional, observational, descriptive study was undertaken. For each call were identified the calling physician, her/his specialty and work setting, the call's object and adequacy, the answer provided, the time needed to connect with the assistance line, the time devoted by the internal medicine physician to provide an answer to the request, and whether the assistance line prevented a visit to the emergency room. Each calling physician was then called back to obtain demographic and professional characteristics, and data relating to the call and to the assistance line. RESULTS: Sixty-three days were analyzed and 276 calls identified. The 237 identified calling physicians were mainly females (54%, n=93), with a mean age of 46 years, graduated from Nantes University (65%, n=86), practicing ambulatory general medicine (69%, n=164) in Loire-Atlantique department area (82%, n=176) for a mean duration of 15 years. Calls were mostly associated with diagnostic challenges (61%, n=166) concerning clinical issues (57%, n=155). A sole telephone advice was the main type of answer provided (56%, n=147) and a visit to the emergency room was prevented for 17% of calls. CONCLUSION: The assistance line activity is adequate with its missions and seems to facilitate patients' healthcare delivery advocating for the development of similar structures in other units. Improvements relating to the information, availability and physicians' training should be considered.

RESUMEN

AIM: The physiopathology of Raynaud's phenomenon (RP) is not currently fully resolved. The cold seems to be not only an important factor triggering attacks, but also inducing RP. The aims of this study were to assess the prevalence of RP in Nantes urban district, and study the relationship between RP prevalence and cold climate. METHODS: Patients aged between 10 and 80 years old, consulting in five Nantes General Practices, from June 2011 and March 2012, were included. Patients presenting RP underwent a full clinical examination. Subjects not meeting Allen and Brown criteria benefited from at least a dosage of Anti-Nuclear Antibodies and a naifold Capillaroscopy. Climate data provided by French national weather agency allowed establishing an average of observed temperatures during the past five years and correlating them to the observed prevalence. RESULTS: Of 954 patients included, 78 had a RP, for an overall prevalence estimated at 8.2%. The prevalence among women (8.9%) was slightly higher than men (7.3%). Secondary form represented 5.1% of RP. In the RP group, 13 patients were active smokers, mean BMI was 22.3±3.2 kg/m², and only 4 patients were treated by vasoconstrictor therapy. According to French national weather agency, between 2007 and 2011, mean temperature of January in Nantes area was 5.8 °C. CONCLUSION: We confirmed that the lower winter temperatures a region experiences, the higher the prevalence of RP, thus raising the question of the physiopathological role of the cold in the induction or in the revelation of RP.

RESUMEN

BACKGROUND: The goal of this study was to examine the impact of subjective and physiological stress responses on medical students' diagnostic reasoning and communication skills. METHOD: A prospective randomized quantitative study was undertaken, looking at ambulatory consultations in internal medicine. On the first day (baseline day), volunteer year 6 students (n = 41) participated in a simulated ambulatory consultation with standardized patients (SPs). On the second day (study day), one week later, they were randomly assigned to two groups: a low stress (n = 20) and a high stress (n = 21) simulated ambulatory consultation. Stress was measured using validated questionnaires and salivary cortisol. The SPs assessed the students' reasoning and communication. The students completed assessments of their clinical reasoning after the consultations. RESULTS: Although stress measures were all significantly higher in the high-stress condition (all p < 0.05), no differences were found in diagnostic accuracy and justification scores. However, correlational analyses revealed a negative correlation between multiple-stress measures and the students' ability to generate arguments for differential diagnoses. CONCLUSION: Stress was associated with impairments in clinical reasoning, of a nature typically suggestive of premature closure.

RESUMEN

Superior vena cava syndrome is a rare disease, most often found to result from a malignant process, which causes extrinsic compression of the superior vena cava. In recent years, there has been an increase of superior vena cava syndrome related to medical devices (implantable site, pacemaker [PM], central venous line for parenteral nutrition...). We report the case of a 37-year-old patient who developed a superior vena cava syndrome 12 years after implantation of a PM. The diagnosis was established on venography after two negative venous-CT focused on the superior vena cava. The superior vena cava syndrome improved immediately after angioplasty and stenting covering the PM probes at the superior vena cava/brachiocephalic venous trunk junction.

RESUMEN

Clinical reasoning is a highly complex system with multiple inter-dependent mental activities. Gaining a better understanding of those cognitive processes has two practical implications: for physicians, being able to analyse their own reasoning method may prove to be helpful in diagnostic dead end; for medical teachers, identifying problem-solving strategies used by medical students may foster an appropriate individual feed-back aiming at improving their clinical reasoning skills. On the basis of a detailed literature review, the main diagnostic strategies and their related pattern of mental processes are described and illustrated with a concrete example, going from the patient's complaint to the chosen solution. Inductive, abductive and deductive diagnostic approaches are detailed. Different strategies for collecting data (exhaustive or oriented) and for problem-building are described. The place of problem solving strategies such as pattern-recognition, scheme inductive process, using of clinical script, syndrome grouping and mental hypotheses test is considered. This work aims at breaking up mental activities in process within clinical reasoning reminding that expert reasoning is characterised by the ability to use and structure the whole of these activities in a coherent system, using combined strategies in order to guarantee a better accuracy of their diagnosis.

RESUMEN

Antithrombin (AT) is a natural anticoagulant and serine protease inhibitor. Hereditary AT deficiencies are uncommon and are associated with a higher risk of venous thrombo-embolism (VTE) compared to other thrombophilias. They are either quantitative (type I) or qualitative (type II) and various mutations have been reported. The II HBS deficiency is caused by a defect in the heparin-binding region (HBS) of AT. This homozygous deficiency increases the risk of VTE. The association with arterial thrombosis is weak but a few cases have been reported. We report a 20-year-old female with recurring arterial thrombosis associated with an AT type II HBS deficiency, due to a homozygous mutation Leu99Phe. In young patients, with recurrent and unexplained arterial thrombosis, a biologic thrombophilia has to be comprehensively searched.

RESUMEN

INTRODUCTION: The face is frequently involved in systemic sclerosis. The main stomatologic manifestations include limited mouth opening, xerostomia, skin atrophy, trigeminal neuralgia. The objective of this study was to describe oral and facial manifestations observed in scleroderma patients from our cohort. METHODS: Between March and October 2006, a stomatologic consultation was included in the follow-up of scleroderma patients seen during consultation or daily hospital in internal medicine or dermatology units. Demographic, clinical and biological data were collected. Stomatologic examination comprised measure of the mouth opening, sugar's and Schirmer's tests, orthopantomogram analysis, and evaluation of the repercussion of symptoms on quality of life using a visual analogical scale (VAS between 0 and 10). RESULTS: This study included 30 patients (women 87 %, mean age 58.6 + or - 13.6 years). Mean duration of systemic sclerosis (n=20 limited cutaneous form, n=10 diffuse form) was eight years. Stomatologic manifestations were: skin atrophy (n=28), peribuccal rhagades (n=25), telangiectasia (n=21), decreased mouth opening (n=20), xerostomia (n=20), xerophtalmia (n=16), periodontal ligament space widening (n=10), bone resorptions (n=2), trigeminal neuralgia (n=1). Xerostomia was considered more discomforting (mean VAS=3.8) than decreased mouth opening (mean VAS=2.6). Xerostomia was the second more discomforting sign of scleroderma and was significantly associated to the limited cutaneous form (p=0.045) and to anticentromeres antibodies expression (p=0.002). Decreased mouth opening was correlated to oesophageal involvement (p=0.025). CONCLUSION: Oral and facial manifestations are frequently observed in scleroderma patients. These manifestations lead to major functional discomfort, mainly due to decreased mouth opening that seems to be frequently associated to oesophageal involvement. Xerostomia is also frequent and is commonly observed in anticentromere antibodies positive cutaneous limited forms of systemic sclerosis. Evolution of radiographic abnormalities like periodontal ligament space widening (33 % of cases), or osteolytic lesions (7 %) is poorly known.

RESUMEN

BACKGROUND: The thrombogenic burden of immobilization remains unknown especially in the medical setting. Most of epidemiological studies estimating the link between risk factors and venous thromboembolism (VTE) have not been designed to evaluate immobilization. The aim of this work was to estimate the risk of VTE in medical bedridden patients by a systematic review and a meta-analysis. METHODS: A research on PUBMED and EMBASE was carried out to retrieve case-control and cohort studies showing the proportion of bedridden patients with or without VTE. Included studies were assigned in six groups according to the following criteria: 1) their design (cohort or case-control), 2) the targeted population (with or without suspicion of VTE) and 3) the medical setting (ambulatory or hospital). Odd-Ratios and Relative Risk for case-control and cohort studies were calculated using a random effect method. Heterogeneity and publication bias were statistically assessed by the I(2) statistics and funnel plots with Egger's tests. RESULTS: 43 studies were included (24181 patients). The pooled RR ranged from 1.46 to 2.77 in the subgroups of cohort studies (n=36) with an overall RR of 1.86 (1.61-2.14; P<0.001). The pooled OR were 2.79 and 2.47 in the two subgroups of case-control studies (n=7), both statistically significant (overall OR: 2.52; 1.70-3.74; P<0.001). Heterogeneity through studies was demonstrated in four subgroups. Publication bias was only observed in one subgroup. CONCLUSIONS: Among medical patients, immobilization increases the risk of VTE. Nevertheless, a specific role of underlying conditions can not be excluded.

RESUMEN

Antiangiogenic agents are an innovative oral chemotherapy prescribed in metastatic renal cancer and gastrointestinal stromal tumors (GIST). These molecules have several side effects. A woman, with moderate hypertension and severe Thevenard's ulceromutilating acropathy, presented renal cancer with lung metastasis. She was treated by antiangiogenic therapy (sunitinib). Under this treatment, she presented some large, extensive, severe and necrotizing ulcerations of both hands and feet, exacerbated with a sepsis. Sunitinib was stopped and antibiotics were combined with surgical trimming leading to clinical remission and complete healing. Sunitinib inhibits both tumor angiogenesis and tumor cell proliferation, but also the preexisting microcirculation. In our case, severe neuropathy caused neurovascular dysregulation which, together with hypertensive microangiopathy, led to a severe hand-foot skin reaction. This microangiopathy worsened under anti-VEGF therapy. The clinical severity was linked to the severity of the neuropathy. To avoid having serious cutaneous consequences, neuropathy and microangiopathy have to be diagnosed before introducing antiangiogenic therapy.

RESUMEN

Leiomyosarcomas are rare malignant mesenchymal tumors. We report the case of a 55-year-old man with a lung metastasis from an iliofemoral leiomyosarcoma mimicking a deep venous thrombosis (DVT). Vascular leiomyosarcoma occurs in the wall of large vessels, and usually presents as unexplained DVT. To date, few cases of peripheral leiomyosarcomas have been described in the literature. This observation demonstrates the usefulness of Positron Emission Tomography (PET), beyond oncologic staging, in such indications as the workup of an unexplained DVT. In this report, PET prevented a misdiagnosis of DVT by showing a peculiar cockade appearance of the vessel. Compared with conventional imaging, PET can provide complementary information. The specificity of such information still needs to be assessed.

RESUMEN

OBJECTIVES: Whereas administration of erythropoietin (EPO) acutely after myocardial infarction (MI) reduces infarct size and chronic EPO therapy attenuates post-MI remodeling, the safety of chronic EPO therapy following MI is unknown. Therefore, we examined the thrombogenic effects of a chronic EPO therapy after MI. METHODS: Rats underwent coronary occlusion followed by reperfusion. They were assigned to one of the following groups: EPO-A, single injection of EPO 5,000 U/kg at the time of reperfusion; EPO-C, injection of EPO 5,000 U/kg at the time of reperfusion followed by 300 U/kg/week; PBS-C, injection of vehicle only. After eight weeks of treatment they were exposed to a validated prethrombotic test based on partial stenosis of the inferior vena cava. RESULTS: As compared to the rats receiving vehicle only, the rats treated with EPO exhibited a significant reduction in MI size (28.7 +/- 2.1% and 25.8 +/- 1.9 vs. 39.8 +/- 3.0% in EPO-A, EPO-C and PBS-C, respectively; p < 0.05). Whereas the hematocrit was significantly increased in EPO-C (59.7 +/- 2.0% vs. 44.7 +/- 0.9% in EPO-A, p < 0.001), the proportion of rats in which a thrombus occurred was similar in all groups (p = 0.52). CONCLUSION: Chronic EPO therapy added to the single high dose of EPO injected acutely did not induce venous pro-thrombotic effect in rats.

RESUMEN

PURPOSE: The increased risk of thromboembolism in acute medical illnesses (AMI) is difficult to assess because of the diversity of medical conditions. The first part of this review of the literature was dedicated to methods of risk analysis based on our current pathophysiological knowledge. This second part describes more specifically the risk of venous thrombosis linked to AMI in hospital, ambulatory and internal medicine settings. CURRENT KNOWLEDGE AND KEY POINTS: The incidence of venous thromboembolism is higher in hospital than in ambulatory setting, albeit the latter remains significant. Stroke and affections leading to intensive care management represent conditions at great risk. Several mechanisms leading to a prothrombotic state have been identified, explaining the increased risk observed during relapses of pathologies specifically treated in internal medicine such as lupus erythematosus, Wegener granulomatosis, inflammatory bowel diseases and Behcet's disease. FUTURE PROSPECTS AND PROJECTS: Next to the pathophysiological understanding of venous thrombosis, the assessment of the specific thrombogenic burden of an AMI is an additive tool to screen medical patients at high risk. This systematic review of the literature shows uncertainties towards some risk factors as bedrest or acute inflammatory response. Taking into account the methodological difficulties inherent to prospective and epidemiological studies, a meta-analysis focusing on these factors would be useful to refine prevention guidelines for venous thromboembolism in medical setting.

RESUMEN

PURPOSE: Some acute medical illnesses are associated with an increased risk of venous thromboembolism. This risk is difficult to assess in medical patients on account of the multiplicity of their pathologies, leading to potential interactions between numerous risk factors. CURRENT KNOWLEDGE AND KEY POINTS: A rational analysis of the risk of venous thrombosis in acute medical setting may be derived from pathogenic models and be based on elementary risk factors for venous thromboembolism classified as transient, permanent, major and intermediate factors. The systematic study of pathophysiological mechanisms in process, in each medical patient could guide the physician attitude toward still non-evaluated situations. FUTURE PROSPECTS AND PROJECTS: A synthesis of the last epidemiological and pathophysiological data is developed in the first part of this literature review, whereas the risk linked to specific situations in ambulatory, hospital or internal medicine settings will be described in the second part.

RESUMEN

BACKGROUND: Inflammatory involvement of extracranial large-sized arteries occurs in 10-20% of patients with giant cell (temporal) arteritis. Aortic involvement may reveal giant cell arteritis or occur as a late-onset complication, and represents one of the most serious manifestation of the disease with the risk of aortic dissection and/or aneurysm rupture. The thoracic aorta is more frequently involved but abdominal aortitis may also occur in giant cell arteritis. To date, few data are available about abdominal aorta changes at the initial stage of giant cell arteritis. PATIENTS AND METHODS: This prospective monocentric study was conducted between May 1998 and May 2002, and included 30 consecutive patients with biopsy-proven giant cell arteritis. Standard clinical and biological data were collected. Each patient underwent an abdominal aortic Doppler-sonography that looked for aneurysm, ectasia, thickening of the vascular wall, and hypoechoic halo around the aorta. RESULTS: Among the 30 patients of this study (25 women, 5 men, mean age 68.5 years), 4 (13%) had an abdominal aortic aneurysm, with a low diameter (23 to 27 mm), measuring 2 to 5.5 cm in length. A vascular wall thickening superior or equal to 3 mm was noted in 17 patients (68%). A 4 to 8 mm periaortic hypoechoic halo was found in 10 patients (33%). This halo was present in 3 out of the 4 patients with aneurysm. CONCLUSION: Aortic involvement is a potentially serious complication of giant cell arteritis. The question of a systematic screening of this complication remains open to discussion. Our study shows that Doppler sonography may detect morphological abnormalities on the abdominal aorta at the initial stage of giant cell arteritis. These abnormalities comprise mild aneurysms, thickening of the vascular wall and periaortic halo, which could correspond to inflammatory locations of the disease. Complementary studies are needed to assess their specificity and their seriousness.

RESUMEN

PURPOSE: Few data are available on the prevalence and causes of hyponatremia in medical setting and to our knowledge, no recent descriptive study has been performed about hyponatremias in the French Departments of internal medicine. METHOD: A "one day" descriptive multicentric study was performed in the medicine departments of the France West area. A questionnaire was mailed to physicians who had to take part in a annual regional meeting about "hyponatremias", one month later. Hyponatremia was defined by a blood sodium level under the normal value of the local laboratory. Each internist had to precise for all hyponatremias in course at the study day, the exact value, the discovery circumstances, the mechanisms and etiologies, the associated diseases, the course and treatments. RESULTS: Seventy-four hyponatremias were identified. The overall prevalence was 12,1%. The prevalence of severe hyponatremias (under 120 mmol/l) was 1,1%. These latter represented 9,4% of the whole hyponatremias (7/74). Associated symptoms and diseases, the mechanisms, the suspected etiologies, the course and treatments are described in detail. CONCLUSION: This multicentric study reports for the first time the prevalence, the clinical and etiological characteristics of hyponatremias coming from Internal Medecine Departments of the West area from France. The overall prevalence is lower in comparison with values usually reported in hospitalized patients, but the frequency of severe and moderate hyponatremias, the mechanisms and the suspected etiologies are identical to those reported in others countries.

RESUMEN

INTRODUCTION: Endobronchial stenoses are rare in the course of Wegener's granulomatosis, and they occur even more rarely than subglottic stenoses. EXEGESIS: We report seven cases of endobronchial stenoses in the setting of Wegener granulomatosis. Neither the pulmonary symptoms nor the systemic manifestations of vasculitis were specific. However 6/7 patients presented a wheezing or an hemoptysis. Bronchial endoscopy has permitted the diagnosis in all cases. Local evolution was cicatricial and symptomatic stenosis in 3 cases (42,8%). CONCLUSION: Thus these lesions must be research in any case of pulmonary abnormality in the course of Wegener's granulomatosis, because they may lead to a pejorative prognosis. Moreover general and local treatment must be given early (at the inflammatory stage). After this stage, the local treatments are difficult and not efficient.

RESUMEN

The pathophysiology of primary Raynaud's phenomenon (Raynaud's disease) remains uncertain but the transmission of this primary microcirculatory dysregulation seems strongly influenced by genetic factors. For a long time, physicians have found that the hereditary factor plays an important role in the genesis of Raynaud's disease. Familial analysis and twin studies have confirmed the role of an hereditary factor. It seems heterogeneous but pedigree analysis indicates the possibility of an autosomal dominant transmission influenced by sex, in some families, allowing an approach called "reverse genetic" based on linkage analysis. Such an approach has focused on few loci but sequencing of candidate genes for genetic mutations remains negative. Given the supposed heterogeneity of the genetic transmission of Raynaud's disease, diversification of strategies in molecular genetics is suitable with reference to techniques applied to multifactorial heredity.

RESUMEN

PURPOSES: Ten to fifteen percent of granulomatous hepatitis are idiopathic. If symptoms like prolonged fever are present, empirical treatment is discussed. The goal of this study is to describe the empirical treatment proposed in this situation by French specialists of internal medicine. METHODS: We conducted a practice investigation among the French national society of internal medicine (SNFMI), using an anonymous questionnaire that related a case of idiopathic granulomatous hepatitis. This questionnaire was proposed to all French internists present at the SNFMI congress in June and December 2004. French specialists of internal medicine had to answer if they would prescribe an empirical treatment and if so, to specify this treatment. RESULTS: Thirty-six French specialists of internal medicine answered to the questionnaire. In the proposed situation, 89% of them initiate an empirical treatment. In 18/36 cases (50%), a first-line anti-tuberculosis empirical treatment is proposed (quadritherapy in 11 cases). In 7 cases (19%), an empirical treatment with prednisone, 0.4 mg/kg/d (N=1) and 1 mg/kg/d (N=6), would be prescribed. Seven internists (19%) would prescribe an empirical treatment with cyclins at the dose of 100 to 400 mg/d. Median duration of the empirical treatment would be 28 days (range: 8-252d). The evaluation parameters mentionned are: fever (69%), weight (59%), seric level of C-reactive protein (59%), and liver biology (53%). In case of failure of first-line empirical treatments, 69% of all questionned internists prescribe a second-line treatments: prednisone at the dose of 0.4 to 2 mg/kg/d (72%), anti-tuberculosis treatments (16%), cyclins 200 mg/d (12%), with a median duration of 28 days. Seven internists (19%) propose to combine two empirical treatments. DISCUSSION: Faced with a problem of idiopathic granulomatous hepatitis, French internists questionned propose four therapeutics options: no treatment, anti-tuberculosis treatment, cyclins or steroids treatment. First-line anti-tuberculosis treatment is a coherent proposition regarding to the high prevalence of tuberculosis. There are only few data available concerning empirical treatment with steroids or cyclins. Specific proposition of such empirical treatments should be defined. CONCLUSIONS: The management of idiopathic granulomatous hepatitis is difficult. Our study shows that therapeutics practices of French internists are heterogenous. The main proposition consists in a first-line anti-tuberculosis empirical treatment, that has to be evaluated after four weeks, and switched with steroids (prednisone, 1 mg/Kg/d) in case of failure. This study is not an expert proposition but contributes to suggest clinical practice guidelines for a rare, complex, heterogenous, and typically internist situation.
