[Evolution of the USP and IPSS score after continuous positive airway pressure sleep apnea therapy at night]. / Évolution du score USP et IPSS après appareillage du syndrome d'apnées du sommeil par pression positive continue nocturne.

INTRODUCTION: To assess the impact of nocturnal continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) on lower urinary tract (LUTS) symptoms. MATERIALS AND METHODS: A prospective, monocentric study was conducted between June 2018 and August 2019. Patients with moderate to severe OSA with an indication for treatment with nocturnal CPAP in combination with SBAU were included. SBAUs and their impact were evaluated by completing two self-administered questionnaires (Urinary Symptom Profile (USP) and International Prostate Score Symptom (IPSS)) filled out during the night-time ventilatory polygraph or diagnostic polysomnography for OSA and after 4 months of CPAP treatment. RESULTS: In 79 patients, after four months of CPAP treatment, USP scores for stress urinary incontinence and overactive bladder were significantly improved, respectively 0.65±1.38 vs 1.13±2.10 ; p<0.0001 and 3.24±2.58 vs 5.43±3.66 ; p<0.0001, IPSS and IPSS-Qdv were significantly improved, respectively 5.20±3.78 vs. 7.44±5.05 ; p<0.0001 and 1.93±1.26 vs. 2.27±1.56 ; p=0.002 as well as IPSS score items on pollakiuria, urgency and nocturia. CONCLUSION: Treatment with CPAP significantly improved SBAU in four months. Testing urology patients for symptoms of OSA in urology patients seeking SBAU would allow referral of patients suspected of OSA to a specialist for diagnosis and management if necessary.

Work-related respiratory symptoms in Champagne vineyard workers.

BACKGROUND: Vineyard workers (VW) are exposed to various respiratory allergens. The aims of the study were to determine the prevalence of work related respiratory symptoms (WRS) in Champagne VW in France and to analyze the relationships between symptoms, occupational exposure and sensitization profile. METHODS: VW of Reims area were prospectively recruited between 2007 and 2010. Demographic and occupational characteristics were recorded. Respiratory symptoms were scored for each month of the past year. Results of respiratory functional tests and skin prick tests for common respiratory allergens, grape moulds and vine pollen were recorded. RESULTS: 307 subjects were included. The prevalence of WRS was 11%. Compared to subjects with symptoms unrelated to work, subjects with WRS were more frequently sensitized to gramineae (34% vs 18%, p = 0.05), described ocular itching (74% vs 37%, p < 0.001) and seasonal symptoms (88% vs 69%, p = 0.03) mainly during lifting and trellising (57% vs 17%, p < 0.001). CONCLUSION: WRS are frequent in Champagne WV and are associated with a sensitization to gramineae and with activities performed close to vine in late spring.

[Medicolegal litigation in cases of occupational lung disease: Some practical tips]. / Le contentieux médical en pathologie professionnelle respiratoire : conseils pratiques.

Recognition and compensation for occupational diseases (OD) is based on the principle of presumption of occupational origin, provided that the disease meets the medical and administrative condition detailed in an OD table appended to the French social security code. A complementary system calling upon a regional committee for recognition of respiratory diseases (CRRMP, in French) attends to cases in which the medical or administrative conditions pertaining to the disease are not fulfilled. Decisions of health insurance funds may be appealed, by employer and employee alike, within the statutory timelines. That said, recent reform of social security litigation and the law of modernization of the justice system have thoroughgoingly modified appeal and redress procedures. Challenge of a decision of non-recognition of the occupational nature of a disease is now addressed to the social pole of the judicial tribunal (JT), which can request the assistance of a CRRMP other than the one that issued the first opinion. As for technical challenges having to do with the date of consolidation (date of the injury) or the degree of partial permanent incapacity (PI), they are put forward in a mandatory preliminary settlement proposal addressed to an amicable settlement board (CRA, in French), whose decisions can be contested face to the social pole of the JT. All judgments regarding medical litigations of social security may be appealed. Information for patients on compensation procedures and available means of remedying decisions by social security is essential to the establishment of the initial medical certificate and to the sequencing of the different phases of expert appraisals, the objectives being to avoid administrative incoherence and inappropriate legal recourse.

Dyspnea assessment in myotonic dystrophy type 1.

In myotonic mystrophy type 1 (DM1), combining respiratory symptom screening and respiratory function testing, is crucial to identify the appropriate time for ventilatory support initiation. Dyspnea has been little investigated in DM1. To provide a multidimensional description of dyspnea, questionnaires assessing dyspnea were administered to 34 consecutive adult patients with DM1 (median (25th-75th centile) age of 36 (28-49), Vital Capacity (VC) of 74 (64-87)% of predicted value). Dyspnea scores were low whatever the questionnaire used: Multidimensional Dyspnea Profile score of 2(0-4.7)/50 for dyspnea sensory descriptor and of 0 (0-4.7)/60 for the emotional descriptor, Visual Analogue Scale score of 0 (0-0)/10 in sitting and supine position and Borg score after six-minute walk test (6MWT) of 2.2 (1.8-4.2)/10. Eleven patients (32%) reported disabling dyspnea in daily living (modified Medical Research Council (mMRC) score ≥ 2). In comparison with patients with mMRC score < 2, patients with mMRC score ≥ 2 had a more severe motor handicap (Muscular Impairment Rating score of 4.0 (4.0-4.0) vs 3.0 (2.0-3.5), p<0.01), a lower 6MWT distance (373 (260-424) vs 436 (346-499)m, p = 0.03) and a lower VC (64 (48-74)% vs 75 (69-89)%, p = 0.02). These data suggest that the mMRC scale might be an easy-to-use and useful tool to assess dyspnea in daily living in DM1 patients. However, the interest of integrating the mMRC dyspnea scale in clinical practice to guide therapeutic management of DM1 patients remains to be assessed in further studies.

[Treatment of GERD in asthma]. / Traitement du reflux gastro-œsophagien dans l'asthme.

Gastro-oesophageal reflux disease (GORD) is one of the most frequent conditions associated with asthma. GORD has an impact on asthma control and quality of life of asthmatic patients. Its treatment relies on lifestyle modifications, anti-acidic treatment with proton pump inhibitors (PPI) and/or surgical management by fundoplication in some situations. The impact of lifestyle modifications has not been analysed on asthma outcomes alone. Several randomised controlled trials assessed the efficacy of PPI on asthma control, peak expiratory flow and/or quality of life. The impact of fundoplication in asthma has mainly been analysed in retrospective or prospective observational studies. This review highlights the limited impact of GORD treatment on asthma control. Current guidelines are to restrict GORD treatment in asthma to asthmatic patients with actual symptomatic GORD. Given the lack of controlled studies, the place of surgical management of GORD in asthma is currently not defined.

[A case of multifocal cavernous haemangiomas of the lung, spleen and bone]. / Hémangiomatose multifocale bronchique, ganglionnaire, splénique et osseuse.

INTRODUCTION: Haemangiomas are vascular malformations, frequently cutaneous, hepatic and splenic. Respiratory involvement and multiple localisations are uncommon. CASE REPORT: We present a rare case of multiple cavernous haemangiomas in a 35 year old woman presenting with repeated haemoptysis. Thoracic CT scanning showed a mass in the left lower lobe associated with lymph node enlargement above and below the diaphragm, heterogeneous splenomegaly and a single spinal lesion without hypermetabolism on PET scanning. Enbronchial ultrasound-guided trans-bronchial needle aspiration was not contributory. Histopathological diagnostic was made firstly by splenectomy with lumbar-aortic curettage and then by lobectomy for haemostasis. A final diagnosis of multiple cavernous haemangiomas involving lung, lymph nodes, spleen and bone was made. CONCLUSIONS: Bronchopulmonary cavernous haemangiomas associated with extra-thoracic lesions are exceptionally rare and their presentation, suggesting, a malignant cause, often leads to surgical resection for diagnostic and, eventually, therapeutic management. We report an original case of cavernous haemangiomas involving lung, lymph nodes, spleen and bone.

[Obesity and asthma: Mechanisms and therapeutic options]. / Asthme et obésité : mécanismes et pistes thérapeutiques.

Asthma and obesity are both common conditions, which lead to a substantial public health burden. The obese-asthma phenotype is characterized by poor asthma control, impaired lung function and decreased efficacy of inhaled treatment. However, this phenotype is highly heterogeneous and involves numerous mechanisms, including systemic inflammation and adipokines. A role for microbiota modifications and genetics has been suggested. Obese-asthma patient management currently consists in weight loss and usual anti-asthmatic treatment. New therapeutic options are being evaluated.

[Systemic lupus erythematosus presenting as severe alveolar hypoventilation and the shrinking lung syndrome]. / Hypoventilation alvéolaire sévère révélant un shrinking lung syndrome lupique.

INTRODUCTION: The shrinking lung syndrome (SLS) is a rare complication of systemic lupus erythematosus. CASE REPORT: A 69-year-old man presented with exertional dyspnoea, muscle weakness, and weight loss of 15kg in 6months. Pulmonary function tests revealed a restrictive lung disorder, with a dramatic decrease in maximal inspiratory pressure (17% of theoretical value), and alveolar hypoventilation (pH 7.43; PaCO2 55mmHg). A thoracic CT-scan showed bilateral diaphragmatic elevation. The creatinine phophokinase level was increased at 280U/L. Progress was marked by a rapidly increasing respiratory acidosis (pH 7.24, PaCO2 109mmHg) requiring invasive ventilation. Auto-immune studies revealed positive anti-nuclear antibodies (1/800) and positive anti-native DNA antibody at 45U/L. Treatment with systemic corticosteroids led to an initial improvement but it was not possible to discontinue mechanical ventilation. The outcome was fatal. Autopsy did not reveal any other cause and a diagnosis of the SLS associated with lupus was confirmed. CONCLUSION: The interesting features of this case report consist of: 1) the presentation of the SLS as an alveolar hypoventilation with a fatal outcome, 2) the presentation of systemic lupus as SLS.

[Eosinophilic pleuritic: An unusual complication of treatment with an angiotensin converting enzyme inhibitor]. / Pleurésie à éosinophiles: une complication rare d'un traitement par inhibiteur de l'enzyme de conversion de l'angiotensine.

BACKGROUND: Eosinophilic pleural effusions are defined by an eosinophil count ≥10% in pleural fluid and represent approximately 10% of exudative pleural effusions. OBSERVATION: We report the first case of eosinophilic pleural effusion occurring due to lisinopril treatment. Improvement after drug discontinuation and recurrence after reintroduction indicated that lisinopril was responsible for the effusion. CONCLUSION: The main causes of eosinophilic pleural effusions are infections including tuberculosis, and malignancies. Drug-induced eosinophilic pleural effusions have only rarely been described, mainly caused by cardiovascular or neuropsychiatric medicines.

[The Proteus syndrome: a rare cause of pulmonary emphysema]. / Le syndrome de Protée : une cause exceptionnelle d'emphysème pulmonaire.

INTRODUCTION: The Proteus syndrome is a rare genetic disease which is characterized by the overgrowth of tissues, especially bone, connective and adipose tissue. This condition is related to a somatic mosaic activating mutation in the AKT1 oncogene. CASE REPORT: We report the case of a 25-year-old man, diagnosed with the Proteus syndrome at the age of 6 months. He exhibited an asymmetric overgrowth of the extremities leading to bilateral amputation of the legs at the age of 10 years. He was hospitalized for acute respiratory failure due to a bronchopulmonary infection. Severe bullous pulmonary emphysema, predominantly on the left, with mediastinal deviation, was diagnosed. The patient recovered with antibiotics. An assessment 2 months later revealed mild hypoxaemia (PaO2=75 mmHg) and severe airflow limitation (FEV1=1260 mL [28% th.], FEV1/V C=69%) with hyperinflation (TLC=7840 mL [107% th.], RV=6010 mL [253% th.]). CONCLUSION: The Proteus syndrome is a very rare cause of pulmonary emphysema. The pathophysiology of emphysema in this syndrome is unknown. It can be hypothesized that the development of pulmonary cysts leading to emphysema may share the same AKT1 activation pathway with lymphangioleiomyomatosis.

[The ceramic-tooth margin in ceramometal prosthesis. A comparative study of three fabrication procedures]. / Le joint céramique-dent en prothèse céramo-métallique. Etude comparative de trois procédés d'élaboration.

This study of the ceramicbutt joint in metal-ceramic prosthesis permits to compare three different laboratory procedures. With the results obtained with two reading processes (numerical measurement and direct measurement of image replicas of S.E.M. to evaluate the marginal gap, it is possible to confirm that: the gold foil method gives the thinnest gap (between 32.7 and 44.7 micrometers) with presence of overcontoured margins. The ceramicbutt joint made by duplicate method, in refractory material, proves to be larger (between 57 and 67.8 micrometers) with overhanging margins, and damaged by sandblasting. The direct elaboration method, on a plaster model, proves to be less precise (gap between 74.6 and 80.4 micrometers) with a round but glossy ceramic margins.
