RESUMEN
Pulmonary metastases due to a pancreatic cancer are difficult to diagnose and demonstrate a wide range of radiological patterns. We report the case of a 37-year-old female patient, without past medical history, with multicystic lung disease in a context of chronic abdominal pain, fatigue and weight loss. After several months of diagnostic delay, pathological examination of surgical lung biopsies led to the diagnosis of secondary deposits of pancreatic cancer. The clinical and radiogical situation deteriorated quickly with the development of alveolar consolidation and Aspergillus superinfection was then diagnosed. This case illustrates the value of an early decision to undertake surgical lung biopsy in the work-up of multicystic lung disease when cancer is suspected. In addition, in the specific context of cancer, faced with clinical and/or radiological deterioration, it is essential to look for infection, particularly aspergillosis.

INTRODUCTION: Hypersensitivity pneumonitis (HP) are typically subacute in their presentation and the diagnosis may be difficult. METHOD: We report a case of a hypersensitivity pneumonitis in a 27-years-old woman, caused by exposure to mould in an insalubrious mobile home. The initial presentation was with acute respiratory distress syndrome complicating RSV pneumonia, treated with ribavirin and corticosteroids in winter 2013-2014. The diagnosis of hypersensitivity pneumonitis was based on clinical and radiological relapse occurring during winter 2014-2015 with confirmed exposure to antigen with fungal sampling at home, respiratory deterioration with antigen rechallenge and a compatible chest CT-scan. CONCLUSION: The diagnosis of hypersensitivity pneumonitis should be considered in similar cases. Treatment is based mainly on removing exposure to the causative antigen.

INTRODUCTION: Pancreatic cancer is often not diagnosed until at a metastatic stage at which point the prognosis is very poor. Pulmonary metastases are pleomorphic, often present at the time of diagnosis and can lead to the discovery of an asymptomatic primary disease. CASE REPORT: We describe two cases aged 60 and 74 years, where imaging identified what was thought to be an interstitial lung disease but which was actually metastasis from pancreatic cancer. In the first case, CT showed multiple excavated pulmonary nodules but the presentation with medullary compression led rapidly to pathological diagnosis on bone lesions. In the second patient, a history of rheumatoid arthritis and the lack of abdominal symptoms led to an initial search for disease related to the rheumatoid disease. Histopathology, from lung and bone biopsies, enabled a correct diagnosis to be achieved. CONCLUSION: Where atypical interstitial lung disease occurs, biopsy should be considered in order not to delay a diagnosis of cancer, especially pancreatic cancer.

Nocardiosis is an infectious disease with wide range of clinical features, which can eventually lead to death. The agent responsible belongs to the genus Nocardia that includes about fifty different species. Nocardiosis occurs mainly in immunocompromised hosts. We report here three cases of disseminated nocardiosis misdiagnosed initially as cerebral metastatic lung cancer. These patients, including two immunocompetent hosts, presented with both pulmonary and cerebral lesions. In all three patients, the diagnosis was based on magnetic resonance imaging with diffusion sequence, apparent diffusion coefficient reconstruction and neurosurgical cerebral biopsies. Treatment with an appropriate antibiotic regimen was prolonged for several months. Progress was favorable with full resolution of the neurological symptoms and the radiological abnormalities. These three cases emphasize the diagnostic challenge of nocardiosis, especially in disseminated disease.

INTRODUCTION: The AIRBAg study screens for bronchial obstruction in dairy farmers. We present the preliminary results after one year. METHODS: A prospective screening study based on questionnaires and electronic mini-spirometry (Néo-6(®)) that includes a representative sample of dairy farmers from the departments of Morbihan and Île-et-Vilaine in Brittany. The dairy farmers had an occupational medicine appointment and, if they demonstrated at least one marker of possible bronchial obstruction (chronic cough, chronic bronchitis, dyspnoea, wheezing, FEV1/FEV6<0.8), they were referred to a pulmonologist. The data we present here were extracted from the occupational medicine appointments because the pulmonologists' appointments are still running. RESULTS: Among the 277 dairy farmers included, 125 (45%) demonstrated "possible bronchial obstruction". The total score of the CAT questionnaire was higher in these farmers (9.1±6.2 versus 5.8±4.0; P<0.0001). In multivariate analysis markers of "possible bronchial obstruction" were eczema, manual foddering and duration of mechanical straw litter spreading. CONCLUSION: Occupational medicine appointments identified markers of "possible bronchial obstruction". We will have the complete results from AIRBAg study in 2015.

INTRODUCTION: There are no French guidelines for the management of complicated parapneumonic effusions. A national observational study was carried out to assess the main features of current clinical practice for this condition. MATERIAL AND METHODS: A questionnaire was sent by email to the 1500 members of the Société de Pneumologie de Langue Française (SPLF) between 15th November and 15th December 2012. RESULTS: There were 92 responders, i.e. a response rate of 6%. Of these, 87 physicians mentioned that they were involved in the management of patients with complicated parapneumonic effusions with a median number of cases of 10 per year (IQR: 5-20). Chest tube drainage was the main approach used for pleural fluid aspiration (n=51/87), followed by repeated thoracentesis (n=29/87) and early surgery (1/87). Five physicians answered both chest tube drainage or repeated thoracentesis and one physician either chest tube drainage or early surgery. Pleural fibrinolytics were never used by 20% of physicians, only in case of loculations by 70% and by 10% of respondents in all cases. Only 3 physicians combined fibrinolytics with DNAse. A double antibiotic dose was used by one third of physicians. All the physicians used respiratory physiotherapy during hospitalization and to aid recovery. Follow-up practices were heterogeneous. CONCLUSIONS: The management of complicated parapneumonic effusions varies significantly in France. National guidelines may be helpful to define best practice and aid in its implementation.

Parapneumonic pleural effusions represent the main cause of pleural infections. Their incidence is constantly increasing. Although by definition they are considered to be a "parapneumonic" phenomenon, the microbial epidemiology of these effusions differs from pneumonia with a higher prevalence of anaerobic bacteria. The first thoracentesis is the most important diagnostic stage because it allows for a distinction between complicated and non-complicated parapneumonic effusions. Only complicated parapneumonic effusions need to be drained. Therapeutic evacuation modalities include repeated therapeutic thoracentesis, chest tube drainage or thoracic surgery. The choice of the first-line evacuation treatment is still controversial and there are few prospective controlled studies. The effectiveness of fibrinolytic agents is not established except when they are combined with DNase. Antibiotics are mandatory; they should be initiated as quickly as possible and should be active against anaerobic bacteria except for in the context of pneumococcal infections. There are few data on the use of chest physiotherapy, which remains widely used. Mortality is still high and is influenced by underlying comorbidities.

Alveolar proteinosis (AP) is a rare disease characterized by alveolar accumulation of surfactant components, which impairs gas exchange. AP is classified into three groups: auto-immune AP defined by the presence of plasma autoantibodies anti-GM-CSF, the most frequent form (90% of all AP); secondary AP, mainly occurring as a consequence of haematological diseases, or following on from toxic inhalation or infections, and genetic AP, which affects almost exclusively children. AP diagnosis is suspected where chest CT-scan demonstrates interstitial lung disease with a crazy paving aspect; and confirmed by bronchoalveolar lavage, which has a milky appearance and contains periodic acid Schiff positive proteinaceous alveolar deposits. The use of surgical lung biopsy to confirm AP is less frequent nowadays. In this context, positive antibodies against GM-CSF indicates an auto-immune etiology of the AP. Concerning management, whole lung lavage is the gold standard therapy. In refractory AP, new treatments are available such as subcutaneous or inhaled GM-CSF supplementation, or rituximab infusions. The clinical course is unpredictable. Spontaneous improvement or even cure can occur, and the 5-year actuarial survival is 95%. The most frequent complications are infectious etiology.

BACKGROUND: Thymic epithelial tumors (TET), including thymomas and thymic carcinomas, are rare and characterized by very different evolutionary patterns depending on histology and invasion stage. The therapeutic management is not well defined but is a subject of increasing interest. The descriptive and analytic objectives of this retrospective monocentric study were to analyze the clinical characteristics of patients with TET, and to assess the management of these tumors in our centre. METHODS: Adult patients with TET managed in the Rennes university hospital in the period 2000-2011 were selected via the pathology department. Their clinical and pathological features and survival were analyzed retrospectively. RESULTS: Fifty TET were retrieved (46 thymomas and 4 thymic carcinomas). Their clinical and histological features and their invasion stages were concordant with published studies. Their diagnostic and therapeutic managements were also in accordance with current guidelines. In univariate analysis, myasthenia and surgery were associated with better survival rates. CONCLUSION: Management of TET in Rennes university hospital is in accordance with guidelines.

INTRODUCTION: Hydroxyurea is an antimetabolite drug used in the treatment of myeloproliferative disorders. Common adverse effects include haematological, gastrointestinal cutaneous manifestations, and fever. Hydroxyurea-induced pneumonitis is unusual. CASE REPORT: A female patient was treated with hydroxyurea for polycythemia vera. She was admitted 20 days after commencing treatment with a high fever, productive cough, clear sputum and nausea. A chest CT-scan showed diffuse ground-glass opacities. Microbiological investigations were negative. The symptoms disappeared a few days after discontinuation of the drug and rechallenge led to a relapse of symptoms. CONCLUSION: Our case and 15 earlier cases of hydroxyurea-induced pneumonitis are reviewed. Two patterns of this disease may exist: an acute febrile form occurring within 1 month of introduction of hydroxyurea and a subacute form without fever. Even if uncommon, one should be aware of this complication of hydroxyurea.

INTRODUCTION: Light chain deposition disease is a rare clinical entity characterized by deposition of monoclonal immunoglobulin light chains in organs. The kidneys are almost always affected, while the lung manifestations that have been reported, including nodular or diffuse disease, especially cystic lesions, are unusual. CASE REPORT: We report the case of a 60-year-old man with a diffuse infiltrative lung disease characterized by numerous apical cysts. The diagnosis of light chain deposition cystic lung disease was obtained by surgical lung biopsy. Light chain deposits in the salivary glands were the only extrapulmonary manifestation. Despite 12 chemotherapy cycles, the patient's lung function and radiological appearances worsened. CONCLUSION: This is the fourth case describing a cystic lung disease due to light chain deposition in the literature. It highlights the need for comprehensive investigations so as not to miss this rare cause of cystic lung disease, which appears to be related to a primary pulmonary lymphoproliferative disorder. The only treatment that appears to be effective is lung transplantation.

The incidence of lung cancer during pregnancy is very low, but it is becoming more frequent in industrialized countries both because of the increase in smoking in young women and because women are becoming pregnant later in life. Usually, the cancer has a poor prognosis due to the presence of metastatic disease at the time of diagnosis. Diagnosis and management are delicate, and should deal with the gestational age, the maternal prognosis, the fetal toxicity of treatments, but also with the worsening of maternal prognosis and the risk of neoplastic cells being transmitted to the fetus in case of delayed treatment. Psychological and ethical considerations complicate the decision process. We present a review of the epidemiology, clinical characteristics, management, and prognosis concerning lung cancer during pregnancy. Finally, it is important to remember that young women with lung cancer should be advised to use a reliable form of contraception.

Bronchoalveolar lavage (BAL) is a major diagnostic tool in lung diseases, including viral respiratory infections. We aimed to better define the situations where viral tests should be performed on BAL fluid (BALF). We retrospectively studied all cases where viral tests [immunofluorescence, immunocytochemistry, viral culture, and/or polymerase chain reaction (PCR)] were performed on BALF during a period of 1 year (2008) in our institution. We compared the characteristics of patients with virus-positive versus virus-negative BALF. Of the 636 BALF samples sent to the microbiology laboratory, 232 underwent viral tests. Of these, 70 (30 %) were positive and identified 85 viruses: herpes simplex virus (HSV)-1 (n = 27), cytomegalovirus (CMV, n = 23), Epstein-Barr virus (EBV, n = 18), human herpesvirus (HHV)-6 (n = 12), respiratory syncytial virus (RSV, n = 3), rhinovirus (n = 1), and adenovirus (n = 1). The variables associated with positive viral tests on univariate analysis were immunosuppression [human immunodeficiency virus (HIV), corticosteroids >10 mg/day for ≥3 weeks, or other immunosuppressive therapy], ground-glass attenuations on computed tomography (CT) scanning, late-onset ventilator-associated pneumonia (VAP), and durations of (i) hospital stay, (ii) intensive care unit (ICU) stay, and (iii) mechanical ventilation before BAL (p < 0.01 for each comparison). On multivariate analysis, only immunosuppression [odds ratio (OR) 6.4, 95 % confidence interval (CI) [2.8-14.3], p < 0.0001] and ground-glass attenuations (OR 3.7, 95 % CI [1.8-7.7], p = 0.0004) remained associated with virus-positive BAL. None of the viral tests performed on BALF for the initial assessment of diffuse infiltrative lung disease (n = 15) was positive. PCR improved the diagnostic yield of viral tests on BALF by 50 %. Testing for viruses on BALF should be mostly restricted to immunocompromised patients with acute respiratory diseases and/or patients with unexplained ground-glass attenuations on CT scanning.

Airway-centered interstitial fibrosis (ACIF) is a distinct type of lung interstitial fibrosis characterized by lesions centered on the airways. Several cases reported in the literature showed little to no effect of corticosteroids and a high mortality rate in the absence of lung transplantation. No other efficient approach is described for the treatment of this type of fibrosis. We report for the first time the case of a 44-year-old patient diagnosed with ACIF on surgical lung biopsy and stabilized with clarithromycin after failure of systemic corticosteroids. We need to confirm this benefit in other patients to ascertain the anti-inflammatory effect of macrolides, which are far less harmful compared to corticosteroids or immunosuppressant drugs.

INTRODUCTION: The yellow nail syndrome is a rare disorder described for the first time in 1964. The pathophysiology remains unclear. Its definition is based on a clinical triad of yellow nails, lymphoedema and chronic respiratory disorders including pleural effusions and bronchiectasis. CASES REPORTS: We describe a retrospective series of five patients diagnosed with the yellow nail syndrome. All the patients were male, aged from 52 to 71 years (median=56). Three patients were diagnosed with the classic triad, whereas the other two had only yellow nails and bronchiectasis. Yellow nails and chronic sinusitis were present in all five patients. We also report atypical manifestations such as a transudative pleural effusion and facial oedema. The yellow nail syndrome was associated with cancer in two cases. CONCLUSION: More common alternative diagnoses must be excluded. The association with cancer should be explored. The treatment is only symptomatic.

Swallowing disorders (or dysphagia) are common in the elderly and their prevalence is often underestimated. They may result in serious complications including dehydration, malnutrition, airway obstruction, aspiration pneumonia (infectious process) or pneumonitis (chemical injury caused by the inhalation of sterile gastric contents). Moreover the repercussions of dysphagia are not only physical but also emotional and social, leading to depression, altered quality of life, and social isolation. While some changes in swallowing may be a natural result of aging, dysphagia in the elderly is mainly due to central nervous system diseases such as stroke, parkinsonism, dementia, medications, local oral and oesophageal factors. To be effective, management requires a multidisciplinary team approach and a careful assessment of the patient's oropharyngeal anatomy and physiology, medical and nutritional status, cognition, language and behaviour. Clinical evaluation can be completed by a videofluoroscopic study which enables observation of bolus movement and movements of the oral cavity, pharynx and larynx throughout the swallow. The treatment depends on the underlying cause, extent of dysphagia and prognosis. Various categories of treatment are available, including compensatory strategies (postural changes and dietary modification), direct or indirect therapy techniques (swallow manoeuvres, medication and surgical procedures).

INTRODUCTION: TNF blockers are widely used to treat inflammatory rheumatic diseases and also in the treatment of extrapulmonary sarcoidosis. TNFα plays a major role in the development and persistence of sarcoid granulomata. However, recent studies have reported the involvement of anti-TNF therapies in the development of granulomatosis associated with the clinical and radiological features of sarcoidosis. CASE REPORT: A 54-years-old man with ankylosing spondylitis was treated with etanercept for two years. He was admitted with symptoms of bronchitis associated with radiological evidence of bilateral pulmonary nodules and a right upper lobe infiltrate. Anti-TNF therapy was stopped even though the patient had received 3 months of prophylactic treatment with rifampicin and isoniazid before starting etanercept. Bronchoalveolar lavage excluded infection, particularly tuberculosis. The chest CT-scan showed bilateral pulmonary nodules with peribronchovascular micronodules and enlarged mediastinal lymph nodes. Surgical lung biopsy was performed and revealed non-caseating granulomata. All the data were consistent with a diagnosis of pulmonary sarcoidosis. The patient remained symptomatic despite discontinuation of etanercept for ten months. Corticosteroids were then introduced, leading to a clinical, functional and radiological improvement. CONCLUSION: This case report underlines the importance of studying the pulmonary complications of TNF blockers. The first priority is to exclude tuberculosis but a diagnosis of sarcoid-like granulomatosis has to be considered. Twenty-three cases have been described in the literature to date.

INTRODUCTION: The macrophage activation syndrome (MAS), also known as haemophagacytosis, is a non-specific clinical syndrome, which includes, among other things general debility, fever and hepatospleneomegaly. The most frequent pathological abnormalities are pancytopenia, hypertryglyceraemia, and hyperferrititinaemia. These clinical and biological criteria, which determine the severity of MAS, must be associated with a histological criterion - haemophagocytosis (with histiocytosis), which is usually medullary but can more rarely be splenic, hepatic or ganglionic. MAS can be primary or secondary. In the latter case, it is frequently associated with an infection of which tuberculosis is the most common. OBSERVATION: We describe the case of a young immunocompetent patient who had disseminated tuberculosis complicated by MAS. CONCLUSION: It is important to be aware of MAS, because its occurrence is associated with a poor prognosis and its optimal treatment, which requires a multidisciplinary approach, has not been fully defined. The optimum strategy in relation to specific aetiologies remains to be clarified.
