Symptoms of Long-COVID 1-Year after a COVID-19 outbreak among sailors on a French aircraft carrier.

OBJECTIVES: While persistent symptoms have been reported after the coronavirus disease-2019 (COVID-19), long-term data on outpatients with mild COVID-19 are lacking. The objective was to describe symptoms persisting for 12 months. METHODS: This prospective cohort study on 1767 sailors of an aircraft carrier in which a Covid-19 outbreak occurred during a mission in April 2020 described predefined self-reported symptoms of Long-COVID at 6, 9 and 12 months. Logistic-regression analyses were used to identify correlates for Long-COVID at months 6, 9 and 12. RESULTS: Among the 641 participants, 619 (35%) completed at least one follow-up questionnaire (413 COVID-positive and 206 COVID-negative). Symptoms of Long-COVID were reported by 53.7%, 55.2% and 54.3% of COVID-positive participants vs 31.2%, 23.3% and 40.0% in COVID-negative patients, at 6 (p <.002), 9 (p <.002) and 12 months (p =.13), respectively. The most frequent symptoms reported were concentration and memory difficulties, asthenia and sleep disorders. CONCLUSION: In this study more than half of COVID-positive outpatients reported persistent symptoms up to 12 months post-quarantine. These findings suggests that all patients, including those with mild disease, can be affected by Long-COVID. A lack of difference at 12 months with COVID-negative patienys prompts caution. The symptoms of Long-COVID are so non-specific that they may be viewed as the consequence of multiple intercurrent factors.

[The role of the pulmonologist in an armed conflict]. / Place du pneumologue en situation de conflit armé.

INTRODUCTION: Recent news points to the eventuality of an armed conflict on the national territory. STATE OF THE ART: In this situation, pulmonologists will in all likelihood have a major role to assume in caring for the injured, especially insofar as chest damage is a major cause of patient death. PERSPECTIVES: The main injuries that pulmonologists may be called upon to treat stem not only from explosions, but also from chemical, biological and nuclear hazards. In this article, relevant organizational and pedagogical aspects are addressed. Since exhaustiveness on this subject is unattainable, we are proposing training on specific subjects for interested practitioners. CONCLUSION: The resilience of the French health system in a situation of armed conflict depends on the active participation of all concerned parties. With this in mind, it is of prime importance that the pneumological community be sensitized to the potential predictable severity of war-related injuries.

[An unusual development following anti-tuberculous treatment: Obstructive inflammatory granuloma]. / Une séquelle peu fréquente après traitement antituberculeux : l'obstruction granulomateuse inflammatoire.

Tuberculosis is a disease that is still a too frequent. Its treatment depends on prolonged, multi-antibiotic, chemotherapy. Progress following treatment is generally good but there is the possibility of parenchymatous or pleural sequelae such as bronchial stenosis due to post tuberculous bronchial fibrosis or bronchiolithiasis. On the other hand, bronchial obstruction after treatment by an inflammatory granuloma is rare. It causes wheezing dyspnoea. In this case, relapse of the tuberculosis was feared, possibly with the development of multi-drug resistance. Treatment with corticosteroids allowed a rapid improvement.

First description of Mycobacterium tuberculosis and M. canettii concomitant infection: report of two cases.

We report the first two cases of tuberculous coinfection with Mycobacterium tuberculosis and M. canettii. Both patients were young Djiboutian females with pulmonary tuberculosis (TB). One had a miliary pattern with concomitant human immunodeficiency virus infection. Both recovered completely with a standard four-drug anti-tuberculosis treatment regimen. Due to the different natural reservoirs and routes of infection of these two strains, our study supports the common belief that multiple strains of infection in TB are related to superinfection rather than concomitant infection.

[Risk factors for thromboembolic disease in young women-the role of hormones]. / Facteurs de risque de maladie veineuse thromboembolique chez les jeunes femmes en contexte hormonal: Risque de survenue d'une maladie thromboembolique veineuse chez les membres de la famille au 1er degré de femmes ayant une maladie veineuse thromboembolique en contexte hormonal : étude « FIT ­ H ¼.

Hormonal exposure in young women increases the risk of venous thromboembolic disease (VTE). Thrombophilia testing is often proposed in women of childbearing age before the initiation of contraception. However, the presence of a familial history of VTE has the potential to be more accurate than the presence of inherited thrombophilia. OBJECTIVE: To demonstrate an association between the risk of VTE in young women with hormonal exposure (pregnancy or oral contraceptive use) and the presence of a previous episode of VTE in their first-degree relatives, according to whether or not a detectable inherited thrombophilia was present. METHODS: We will perform a multicenter case-control cross-sectional study. The main risk factor is defined by the presence of a symptomatic VTE in young women with hormonal exposure. The principle variable is the presence of an objectively diagnosed episode of VTE in first-degree relatives. We will need to include 2,200 family members in 440 cases. EXPECTED RESULTS: We expect to improve understanding of the thrombotic risk in first-degree relatives of patients in hormonal context with or without a past history of VTE.

[Asbestos in the National Navy: Employment-exposure matrix]. / L'Amiante dans la Marine nationale : matrice emploi-exposition.

INTRODUCTION: The odd risk ratio for an asbestos-related disease is 6.9 for National Defense personnel and 94% of the victims who are compensated belong to the French Navy. While employment-exposure matrices exist for the civilian environment, none are available to the military. Our work consists of the creation of the first employment-exposure matrix in the French Navy, in order to optimize post-occupational medical surveillance. METHOD: We conducted a bibliographic search for asbestos in naval repair, naval embarking and foreign navies. From databases such as Medline, Pubmed, we used the following keywords "Navy", "Asbestos", "Shypyard" and "Military" and we have extended ourselves to the registers of existing theses on the subject. RESULTS: Epidemiological and bibliographic data confirm the increased risk in the French Navy. Three variables are important in the proposal of this employment-exposure matrix: employment, year of arming the ship and duration of embarkation. There is a major risk for personnel whose work is in direct contact with asbestos, in particular machine personnel, irrespective of their duration of exposure. For embarked personnel who do not have direct contact with asbestos in their jobs, the increase in risk depends essentially on the ship's year of arming and the presence of asbestos, whether or not on board, as well as the duration of exposure of seafarers. CONCLUSION: These results allow us to recommend a classification of the risk in accordance with the recommendations of the French Health Authority and to propose an adequate post-professional follow-up for the personnel of the Navy.

[Cannabis "bong": A frequent, original and dangerous way of consumption]. / Le « bang ¼ de cannabis, un mode de consommation original, fréquent et dangereux.

The bong is a water pipe craft, used to smoke tobacco or cannabis. The benefit of consuming cannabis as a "bang" is based on the intensity and speed of the effect. The cannabis intoxication can then be associated with disorders of sensory functions, the type of distortion of perceptions or hallucinations, often accompanied by intense anxiety. Bong cannabis consumption appears to be responsible for specific side effects (especially hemoptysis), possibly related to the importance of inhalation of products of combustion of cannabis and combustion of plastic parts used in its manufacture.

[Diagnosis of a systolic murmur among young asymptomatic patient: An assessment of professional practices for the expertise in military medicine]. / Diagnostic d'un souffle systolique cardiaque chez un jeune patient asymptomatique : une évaluation des pratiques professionnelles en médecine militaire d'expertise.

UNLABELLED: The finding of a systolic heart murmur is common in medical military practice. Albeit often benign among young healthy adults, it can reveal a valvular or a cardiac disease, which could worsen during workout or expose to risk of a sudden death. This study aims to evaluate the diagnostic efficiency of the military general practitioner when discovering a systolic murmur among young asymptomatic patients. MATERIALS AND METHODS: During one year, this study involved all the general practitioners of the medical military centres of Brittany and the cardiologists of the military hospital in Brest. It prospectively enrolled a cohort of all military asymptomatic patients under 40, without any underlying known heart condition. Military general practitioners listed, thanks to an anonymous form, the main features of the systolic murmur and of the ECG and proposed an auscultatory diagnosis: innocent or organic murmur. Then cardiologists did the same and finally performed a transthoracic echocardiography giving the diagnosis. RESULTS: Fifty-eight patients were referred, 5 not meeting the inclusion criteria. Of the 53 patients included, military general practitioners found 46 innocent murmurs and 7 organic ones. Cardiologists found 51 innocent murmurs and 2 organic. Transthoracic echocardiography just took on one organic murmur (linked with a bicuspid aortic valve), spotted by the specialist, though judged innocent by the general practitioner. DISCUSSION: Most of innocent murmurs diagnosed by general practitioners (45/46) were confirmed. Regarding the seven organic murmurs, the main selected criteria (intensity over 3, orthostatic persistence, diffuse irradiation) are mostly in accordance with the literature, proving right medical instincts. Authors propose a practical management of systolic murmurs among asymptomatic young patients. CONCLUSION: Military general practitioners seem to master symptoms of organic murmur. This assessment argues for a promotion of a holistic clinical examination, which will help not only to rationalize the use of transthoracic echocardiography in economic terms but also to value the medical expertise.

[Echographic diagnosis of systolic murmur among 280 young French militaries. Implications for the expertise in military medicine]. / Diagnostic échographique d'un souffle cardiaque systolique au sein d'une population de 280 jeunes militaires français. Implications en médecine d'expertise militaire.

UNLABELLED: Clinically discovering a systolic murmur is frequent among the young military population. When this murmur does not sound benign, a transthoracic echocardiography (TTE) is made to detect any cardiopathy, which could cause sudden cardiac death. The aim of this study was to evaluate the interest of systematic TTE in the assessment of any cardiac systolic murmur (CSM) among militaries. METHODS: We ran a retrospective monocentric study in the "Clermont-Tonnerre" military hospital in Brest. We included all patients sent for TEE, aged 15 to 30 years old, from the 1st January 2010 until the 31st July 2013. RESULTS: Two hundred and eighty TTES assessing CSM were performed. We found 28/280 (10%) echocardiographic abnormalities: 13 were bicuspid aortic valves (4.6%), 6 were ventricular septal defects (2.15%), 3 were atrial septal defects (1.07%), 4 were mild mitral regurgitations (1.43%), one mild pulmonary stenosis (0.35%) and one aortic stenosis (0.35%). No hypertrophic cardiomyopathy was found. Concerning military expertise, 11 (3.92%) patients among these 28 with abnormal TEE were considered unfit for work or "fit for work with limitations". CONCLUSION: Assessing a cardiac systolic murmur with TEE lead to the diagnosis of a cardiomyopathy in 10% of the case. This study enhances the importance of systematic TEE when a CSM is detected in the young military, in order to determine if those soldiers can still fulfill their military duty.

[Practical conduct for patients with a lonely hypoxemia at rest or during exercise]. / Démarche diagnostique d'une hypoxémie « nue ¼ de l'adulte.

INTRODUCTION: Hypoxemia is a decrease in blood oxygen partial pressure. This work aims at presenting a practical conduct for patients with a lonely hypoxemia at rest or during exercise, defined by the absence of dyspnea at rest, obvious clinical or radiographic abnormality. STATE OF THE ART: Diagnostic tools available to the clinician are clinical examination, CT scan, echocardiography, hyperoxia test, trans cranial ultrasound and lung scintigraphy. This work proposes a practical diagnostic approach, with a main role of chest CT. PERSPECTIVES: Work is underway to determine more precisely the place of echocardiography for the diagnosis of intra or extra cardiac shunts. CONCLUSIONS: The finding of a lonely hypoxemia requires careful diagnostic approach to quickly rule out potentially serious causes and not to disregard the rare causes.

[Systematic implementation of transthoracic echocardiography, transesophageal echocardiography and 24-hour Holter ECG for the detection of cardiac sources of embolism in patients with stroke or transient ischemic attack. A retrospective study of 220 patients]. / Rentabilité diagnostique de l'échographie cardiaque transthoracique, transœsophagienne et du Holter ECG réalisés à titre systématique lors du bilan étiologique d'un premier accident vasculaire cérébral ischémique. Étude rétrospective de 220 patients.

INTRODUCTION: Embolism of cardiac origin accounts for around 20% of ischemic strokes. ECG and transthoracic echocardiography (TTE) are commonly obtained during the evaluation of patient of ischemic stroke but specific indications for the transesophageal (TEE) echocardiography and 24-hour Holter ECG (Holter) remain uncertain. OBJECTIVES: The aim of this study is to report the contribution of TTE, TEE and Holter performed as a routine during the evaluation of patients with ischemic stroke (IS) or transient ischemic attack (TIA). METHODS: This is a retrospective single-center study of 220 patients hospitalized between 1st January 2007 and 31st December 2010 for a first IS or TIA. RESULTS: One hundred and forty-three IS and 77 TIA are identified. The average age of patients was 66 years (18-88 years). TTE/TEE/24-hour Holter allowed the diagnosis of cardiac sources of embolism in 135 patents (61.3%). TTE/TEE identified potential source of cardiogenic embolism in 126 patients (52.2%). Twenty four-hour Holter ECG tracked supraventricular arrhythmia in 15 patients (6.7%), 9 (4%) which had non-contributory ultrasound assessment. CONCLUSION: The systematic implementation of TTE/TEE/Holter is useful for identifying potential sources of cardiogenic embolism. The performance of TEE remains above the TTE. Holter should be recommended because it is a cost effective and non-invasive tool.

[Evaluation of preoperative non-invasive ventilation in thoracic surgery for lung cancer: the preOVNI study GFPC 12-01]. / Évaluation de la ventilation non invasive préopératoire avant chirurgie de résection pulmonaire. Étude préOVNI GFPC 12-01.

BACKGROUND: Surgical resection is the best treatment for stage I and II non-small cell lung cancer. Despite an improvement in the perioperative management of cancer patients and specialization of surgical teams, morbidity and mortality remains significant. Non-invasive ventilation (NIV) is an effective therapeutic option in hypercapnic respiratory failure. It also improves functional and gasometric parameters when undertaken before surgery. The objective of the preOVNI study is to demonstrate that preoperative non-invasive ventilation for 7 days, at home, reduces the postoperative respiratory and cardiovascular complications of lung resection surgery, in a high-risk population. METHODS: A prospective, randomized, controlled open-labelled multicentric French study, under the supervision of the Groupe Français de Pneumocancérologie (GFPC), comparing 7 days of preoperative non-invasive ventilation with standard treatment. Inclusion criteria are: patients suitable for lobectomy or segmentectomy for primary bronchial carcinoma and presenting with obstructive or restrictive lung disease, obesity or chronic cardiac insufficiency. The primary criterion is a composite one, including all respiratory and cardiac complications. The number of patients is 150 in each treatment arm, 300 in total. EXPECTED RESULTS: We think that preoperative NIV will be able to reduce the rate of postoperative complications. If this objective is achieved, the management of these patients could be changed.

[EGFR activating mutation in lung adenocarcinoma: risk factor of thromboembolic event?]. / Mutation EGFR dans les adénocarcinomes broncho-pulmonaires: facteur de risque de MVTE ?

Cancer is a known risk factor for the development of venous thromboembolism (VTE) and in particular, adenocarcinoma of the lung is known to be associated with a higher risk of thromboembolic event. EGFR activating mutations are more frequently found in this histological subtype than in other lung cancers. We report three cases of VTE in patients with adenocarcinoma of the lung and EGFR activating mutation. Our reported case series is atypical because the VTE event occurred early in the adenocarcinoma history: either leading to the diagnosis of cancer, or appearing very early in the management of the neoplasm.

[Discovery of a yellow nail syndrome with major hypothyroidism]. / Découverte d'un syndrome des ongles jaunes lors d'une insuffisance thyroïdienne majeure.

The yellow nail syndrome is rare. It associates the triad: yellow nails, lymphedema and thoracic events. We report two cases of this syndrome with major hypothyroidism. These observations suggest an association between these two diseases.

[Septic pulmonary embolism after removal of a venous access device for septic thrombophlebitis]. / Emboles pulmonaires septiques après ablation d'une chambre implantable pour thrombophlébite septique.

Septic thrombophlebitis on a central venous access device (CVAD) is a rare and serious complication. According to current guidelines, the device should be removed and antibiotics be given. The risk of septic thrombophlebitis is related to the migration of septic emboli to the lung, a potentially fatal event, particularly in frail patients with lung cancer. We report a case observed in a 66-year-old man with multiple metastatic lung cancer who had a CVAD and who developed septic thrombophlebitis leading to coagulase-negative staphylococcal bacteriemia. After removal of the CVAD, the thrombophlebitis was complicated by pulmonary embolism affecting the entire network of the right lung.

[Pulmonary sarcomatoid carcinoma: Clinical and prognostic characteristics, a case report]. / Particularités cliniques et évolutives des carcinomes sarcomatoïdes du poumon: à propos d'un cas.

Sarcomatoid carcinoma is a rare malignancy in the family of non-small-cell lung cancer. They belong to a mixed group of poorly differenciated neoplasia, including sarcomatous cells or sarcomatoid-like cells with giant or spindle cells. We report the case of a 69-year-old man with sarcomatoid carcinoma. We describe the main characteristics of these tumors. Diagnosis is frequently delayed and lesions are locally advanced. The prognostic is poorer than other non-small-cell lung cancer. Chemotherapy is often not efficient.

[Acute chest syndrome of adults suffering from sickle cell disease]. / Le syndrome thoracique aigu de l'adulte drépanocytaire.

UNLABELLED: Sickle cell disease is a common but often poorly understood by chest physicians. The acute chest syndrome represents its main respiratory complication. STATE OF ART: Sickle cell disease is an autosomal recessive disorder inducing, in certain circumstances, sickling of red cells. Natives from western or central Africa and from the Caribbean islands are mainly affected. Acute chest syndrome is defined by the association of chest pain or fever and recent radiographic infiltrates, in patients suffering from sickle cell disease. Determination of etiology, infection, fat embolism or hypoventilation, is difficult, as a self-perpetuating vicious circle is ongoing. Support, largely undervalued, is based on etiological treatment and measures to avoid worsening linked to complications, especially microcirculatory disease. CONCLUSIONS: Acute chest syndrome is a severe respiratory complication of sickle cell disease. Therapeutic measures are simple but undervalued.
