Individual trajectory-based care for COPD: getting closer, but not there yet. ERJ Open Res 2021; 7:00451-2021.

Abstract
Chronic obstructive pulmonary disease (COPD) is a main cause of death due to interplaying factors, including comorbidities that interfere with symptoms and response to therapy. It is now admitted that COPD management should be based on clinical symptoms and health status and should consider the heterogeneity of patients' phenotypes and treatable traits. This precision medicine approach involves a regular assessment of the patient's status and of the expected benefits and risks of therapy. The cornerstone of COPD pharmacological therapy is inhaled long-acting bronchodilation. In patients with persistent or worsened symptoms, factors likely to interfere with treatment efficacy include the patient's non-adherence to therapy, treatment preference, inhaler misuse and/or comorbidities, which should be systematically investigated before escalation is considered. Several comorbidities are known to impact symptoms, physical and social activity and lung function. The possible long-term side-effects of inhaled corticosteroids contrasting with their over-prescription in COPD patients justify the regular assessment of their benefits and risks, and de-escalation under close monitoring after a sufficient period of stability is to be considered. While commonly used in clinical trials, the relevance of routine blood eosinophil counts to guide therapy adjustment is not fully clear. Patients' characteristics, which define phenotypes and treatable traits and thus guide therapy, often change during life, forming the basis of the concept of clinical trajectory. The application of individual trajectory-based management of COPD in clinical practice therefore implies that the benefit:risk ratio is regularly reviewed according to the evolution of the patient's traits over time to allow optimised therapy adjustments.

Etiological Work-Up for Adults with Bronchiectasis: A Predictive Diagnostic Score for Primary Ciliary Dyskinesia and Cystic Fibrosis. J Clin Med 2021; 10:jcm10163478. [PMID: 34441774 PMCID: PMC8397090 DOI: 10.3390/jcm10163478] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 07/30/2021] [Accepted: 08/02/2021] [Indexed: 11/16/2022] Open
Abstract
Background: etiological investigations are not done for all adult patients with bronchiectasis because of the availability and interpretation of tests. The aim of the study was to elaborate a score to identify patients at high risk of having cystic fibrosis or primary ciliary dyskinesia (CF/PCD), which require appropriate management. Methods: diagnostic work-ups were carried out on a French monocenter cohort, and results were subjected to logistic-regression analyses to identify the independent factors associated with CF/PCD diagnosis and, thereby, elaborate a score to validate in a second cohort. Results: among 188 patients, 158 had no obvious diagnosis and were enrolled in the algorithm-construction group. In multivariate analyses, age at symptom onset (8.69 (2.10–35.99); p = 0.003), chronic ENT symptoms or diagnosed sinusitis (10.53 (1.26–87.57); p = 0.03), digestive symptoms or situs inversus (5.10 (1.23–21.14); p = 0.025), and Pseudomonas. aeruginosa and/or Staphylococcus aureus isolated from sputum (11.13 (1.34–92.21); p = 0.02) are associated with CF or PCD. Receiver operating characteristics curve analysis, using a validation group of 167 patients with bronchiectasis, confirmed the score’s performance with AUC 0.92 (95% CI: 0.84–0.98). Conclusions: a clinical score may help identify adult patients with bronchiectasis at higher risk of having CF or PCD.

Abstract
The Pneumo-Quest self-questionnaire was developed to standardize the practice of recollection when welcoming a new patient. It consists of 82 main questions and 34 subsidiary questions to be completed at home by the patients before their first visit to a pulmonologist. This evaluation was carried out on the basis of 137 returned questionnaires. The feasibility (main criterion) was good with 93±5% of the questions answered and an average completion time of 15.1±9.8minutes (mean±SD). The reliability of the responses (secondary criterion) was good with the agreement between the patient's response and the doctor's opinion being excellent or good for the majority of medical histories and treatments, as evidenced by the high values of the kappa coefficient (>0.90; <0.90; <0.75). Patient and physician perception of the questionnaire was good with 99% and 90% positive ratings, respectively. The use of the questionnaire was unhelpful in the course of the consultation in only 2% of cases. Doctors found the tool useful for obtaining a comprehensive history in 87% of cases and patients declared that it helped them "forgot nothing" in 93% of the cases. The questionnaire helped the doctor to identify the patient's problems rapidly in 71% of cases and saved time in 64%. These positive results encourage a wide dissemination of the questionnaire (www.pneumo-quest.com).

Abstract
Vaccines have saved millions of lives and reduced the severity of many infections. A reduction in vaccination coverage is now reflected in the re-emergence of epidemics of mumps, pertussis, measles and chickenpox. Many people do not recognize the effectiveness of vaccination and fear the side effects. The main concern is the safety of vaccines. Lack of information weighs less than lack of trust in health authorities. The greater responsibility of the individual and the respect for his free will, may lead the authorities to a less vigourous promotion of the "vaccination duty" which is also a social duty. The attitude of individuals is guided by their health beliefs which are often supported by an erroneous perception of risk. In addition, insidious anti-vaccine lobbying plays on fears and uses biased reasoning that the media help to amplify. Thus the analysis of the brakes to vaccination both in the general population and among health professionals, the dismantling of the arguments developed by the anti-vaccine leagues and vigilance with regard to "fake news" should allow a concerted communication, transparent, clear and effective, in order to limit the occurrence of preventable deaths.

Abstract
Purposes Following a hospitalization for COPD, dual and triple therapies were compared in terms of persistence and relations with outcomes (exacerbations, health care resource use and costs). Methods This was a historical observational database study. All patients aged ≥45 hospitalized for COPD between 2007 and 2015 were identified in a 1/97th random sample of French claims data. Patients receiving dual therapy within 60 days after hospitalization were compared to patients receiving triple therapy, after propensity score matching on disease severity. Results Of the 3,089 patients hospitalized for COPD, 1,538 (49.8%) received either dual or triple therapy in the 2 months following inclusion, and 1,500 (48.6%) had at least 30 days of follow-up available; 846 (27.4%) received dual therapy, and 654 (21.2%) received triple therapy. After matching, the number of exacerbations was 2.4 per year in the dual vs 2.3 in the triple group (p=0.45). Among newly treated patients (n=206), persistence at 12 months was similar in the dual and triple groups (48% vs 41%, respectively, p=0.37). As compared to patients on dual therapy, more patients on triple therapy received oral corticosteroids (49.1 vs 40.4%, p=0.003) or were hospitalized for any reason (67% vs 55.8%, p=0.0001) or for COPD (35.3 vs 25.1%, p=0.0002) during follow-up. Cost of care was higher for patients on triple than for those on dual therapy (€11,877.1 vs €9,825.1, p=0.01). Conclusion Following hospitalizations for COPD, patients on dual and triple therapy experienced recurrent exacerbations, limited adherence to therapies and high cost of care. Patients on triple therapy appeared more severe than those on dual therapy, as reflected by exacerbations and health care resource use.

Are Systemic Manifestations Ascribable to COPD in Smokers? A Structural Equation Modeling Approach. Sci Rep 2018; 8:8569.

Abstract
Whether the systemic manifestations observed in Chronic Obstructive Pulmonary Disease (COPD) are ascribable to lung dysfunction or direct effects of smoking is in debate. Structural Equations Modeling (SEM), a causal-oriented statistical approach, could help unraveling the pathways involved, by enabling estimation of direct and indirect associations between variables. The objectives of the study was to investigate the relative impact of smoking and COPD on systemic manifestations, inflammation and telomere length. In 292 individuals (103 women; 97 smokers with COPD, 96 smokers without COPD, 99 non-smokers), we used SEM to explore the pathways between smoking (pack-years), lung disease (FEV1, KCO), and the following parameters: arterial stiffness (aortic pulse wave velocity, PWV), bone mineral density (BMD), appendicular skeletal muscle mass (ASMM), grip strength, insulin resistance (HOMA-IR), creatinine clearance (eGFR), blood leukocyte telomere length and inflammatory markers (Luminex assay). All models were adjusted on age and gender. Latent variables were created for systemic inflammation (inflammatory markers) and musculoskeletal parameters (ASMM, grip strength, BMD). SEM showed that most effects of smoking were indirectly mediated by lung dysfunction: e.g. via FEV1 on musculoskeletal factor, eGFR, HOMA-IR, PWV, telomere length, CRP, white blood cells count (WBC) and inflammation factor, and via KCO on musculoskeletal factor, eGFR and PWV. Direct effects of smoking were limited to CRP and WBC. Models had excellent fit. In conclusion, SEM highlighted the major role of COPD in the occurrence of systemic manifestations while smoking effects were mostly mediated by lung function.

Abstract
The Société de Pneumologie de Langue Française proposes a decision algorithm on long-term pharmacological COPD treatment. A working group reviewed the literature published between January 2009 and May 2016. This document lays out proposals and not guidelines. It only focuses on pharmacological treatments except vaccinations, smoking cessation treatments and oxygen therapy. Any COPD diagnosis, based on pulmonary function tests, should lead to recommend smoking cessation, vaccinations, physical activity, pulmonary rehabilitation in case of activity limitation, and short-acting bronchodilators. Symptoms like dyspnea and exacerbations determine the therapeutic choices. In case of daily dyspnea and/or exacerbations, a long-acting bronchodilator should be suggested (beta-2 agonist, LABA or anticholinergics, LAMA). A clinical and lung function reevaluation is suggested 1 to 3 months after any treatment modification and every 3-12 months according to the severity of the disease. In case of persisting dyspnea, a fixed dose LABA+LAMA combination improves pulmonary function (FEV1), quality of life, dyspnea and decreases exacerbations without increasing side effects. In case of frequent exacerbations and a FEV1≤70%, a fixed dose long-acting bronchodilator combination or a LABA+ inhaled corticosteroids (ICS) combination can be proposed. A triple combination (LABA+LAMA+ICS) is indicated when exacerbations persist despite one of these combinations. Dyspnea in spite of a bronchodilator combination or exacerbations in spite of a triple combination should lead to consider other pharmacological treatments (theophylline if dyspnea, macrolides if exacerbations, low-dose opioids if refractory dyspnea).

Abstract
INTRODUCTION Primary ciliary dyskinesia (PCD) is a genetic disease characterised by abnormalities in ciliary function, responsible for chronic pulmonary and sinonasal diseases. Adult clinical features and outcome are poorly described. OBJECTIVES To assess the clinical characteristics and disease progression in adults with PCD. METHODS Bicentric retrospective study, focusing on adults (≥18 years) with an asserted diagnosis of PCD based on the presence of bronchiectasis with typical ultrastructural defect of cilia and/or situs inversus (SI). Clinical symptoms, respiratory function, extent of bronchiectasis, microbiology and molecular analysis were assessed. Results are expressed as median (25th; 75th centile). RESULTS 78 patients were included with a median follow-up of 8.1 years. 91% of patients had respiratory symptoms and 95% had chronic rhinosinusitis. Half of ultrastructural defects concerned dynein arms. Respiratory function was significantly lower in women (FEV1=60% predicted (50; 76), vs 77% (62; 95), p=0.009) and in patients with chronic airway Pseudomonas aeruginosa (PA, n=21) infection (FEV1=60% (48; 71) vs 75% (55; 89), p=0.04). FEV1 was associated with gender (regression coefficient for men =13.8, p=0.009), chest CT score (r=-0.42, p<0.001) but not with age at diagnosis, SI or body mass index. FEV1 decline was -13.4 mL/year (-42.8; +11.9) and was greater in women (-29.3 mL/year, (-59.7; -11.9), vs -2.0 mL/year (-26.9; +25.4), p=0.002). Three patients had severe respiratory failure. CONCLUSIONS Alteration of respiratory function in adults with PCD is heterogeneous and usually moderate but appears more severe in women and in patients with chronic PA infection. Only 4% of patients develop chronic respiratory failure.

Abstract
AbstractBackground:Bordetella pertussisis highly contagious, and because immunity wanes after vaccination, it continues to be a cause of cough among adults.Objective:To describe the healthcare services used and productivity losses accrued by healthcare workers (HCWs) missing work due to pertussis.Methods:After 3 pertussis cases were confirmed among HCWs, all hospital employees and patients with a cough were screened between November 2000 and March 2001. Each potential case underwent diagnostic tests and received antibiotics (spiramycin or azithromycin) when appropriate. Symptomatic employees were not allowed to return to work until they received an antibiotic for at least 5 days. Services used (physician visits and calls, antibiotics, diagnostic tests, hospitalization, and treatment provided to their contacts) were combined with cost estimates (in 2002 euros) for these services in France.Results:Ninety-one potential cases were identified (77 HCWs, 12 patients, and 2 family members). Of them, 89% received antibiotics and 22% had at least one contact who was also treated. Approximately half (55%) of the HCWs who were cases missed 5 days of work. Four patients were admitted to the hospital as a result of the infection. The average medical cost was 297 euros per potential case: diagnostic tests accounted for 32% and hospitalization for 31%. Total cost (medical and productivity) was 46,661 euros for 91 cases, 42% from productivity losses. An investigation to identify these potential cases also accrued additional costs.Conclusion:Serious adverse health and economic consequences arose from transmission of pertussis among HCWs, their families, and patients.

Abstract
BACKGROUND Early identification of acute exacerbations of COPD facilitates better care. This study was designed to validate a short questionnaire (Exascore) developed to help patients, relatives and carers to diagnose acute exacerbations. METHOD We first addressed content validity that allowed the elaboration of two questionnaires, one assessing the current status and the other stable status (transition). The second step tested their construction validity, reproducibility and concomitant validity among 126 COPD patients aged 64.4±9.9 years. They included 56 presenting with an exacerbation and 70 in stable state, of whom 57 completed the questionnaire a second time after 7 days. The diagnosis of exacerbation and assessment of severity (gold standard) were established by the treating respiratory physician and confirmed by two independent experts. RESULTS Factorial analyses established a "current status" questionnaire comprising 8 items and 2 dimensions. Cronbach's alpha coefficients were satisfactory, 0.867 for "respiratory impact", 0.886 for "psychosocial impact" and 0.886 for the total score. Concomitant validity and reproducibility were also adequate. The transition questionnaire did not obtain convincing psychometric results. CONCLUSIONS The "current status" Exascore questionnaire satisfies psychometric quality criteria while being usable in clinical practice. It helps in diagnosing acute exacerbations and assessing their intensity. Further studies will need to test the adequacy of proposed thresholds, the factorial structure of the score in healthcare professionals and patients' relatives, and its predictive power.

Abstract
Rationale Chronic obstructive pulmonary disease (COPD) is often associated with age-related systemic abnormalities that adversely affect the prognosis. Whether these manifestations are linked to the lung alterations or are independent complications of smoking remains unclear. Objectives To look for aging-related systemic manifestations and telomere shortening in COPD patients and smokers with minor lung destruction responsible for a decline in the diffusing capacity for carbon monoxide (DLCO) corrected for alveolar volume (KCO). Methods Cross-sectional study in 301 individuals (100 with COPD, 100 smokers without COPD, and 101 nonsmokers without COPD). Measurements and Main Results Compared to control smokers, patients with COPD had higher aortic pulse-wave velocity (PWV), lower bone mineral density (BMD) and appendicular skeletal muscle mass index (ASMMI), and shorter telomere length (TL). Insulin resistance (HOMA-IR) and glomerular filtration rate (GFR) were similar between control smokers and COPD patients. Smokers did not differ from nonsmokers for any of these parameters. However, smokers with normal spirometry but low KCO had lower ASMMI values compared to those with normal KCO. Moreover, female smokers with low KCO, had lower BMD and shorter TL compared to those with normal KCO. Conclusions Aging-related abnormalities in patients with COPD are also found in smokers with minor lung dysfunction manifesting as a KCO decrease. Decreased KCO might be useful, particularly among women, for identifying smokers at high risk for aging-related systemic manifestations and telomere shortening.

Nocturia is an independent predictive factor of prevalent hypertension in obstructive sleep apnea patients. Sleep Med 2015; 16:652-8. [PMID: 25862119 DOI: 10.1016/j.sleep.2014.10.019] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2014] [Revised: 10/14/2014] [Accepted: 10/25/2014] [Indexed: 10/24/2022]
Abstract
OBJECTIVE The aim of this study was to determine whether nocturia is an independent predictor for prevalent hypertension in obstructive sleep apnea (OSA). METHODS We analyzed data from a national prospective clinical cohort of OSA patients participating in the French national prospective registry. Anthropometric data, comorbidities, OSA severity, and number of voids/night were included in multivariate analyses to determine the independent variables associated with prevalent hypertension. RESULTS A total of 22,674 OSA patients were included, of which 11,332 were hypertensive. The prevalence of hypertension among OSA patients was about 1.3 times higher in patients suffering from nocturia at 61.45% versus 46.52% in hypertensive and non-hypertensive OSA patients (p <0.001). There was a significant positive relationship between hypertension and the severity of nocturia beyond two voids/night: two voids/night versus none: odds ratio (OR) = 1.270 (95% confidence interval (CI) = 1.175; 1.372), three voids/night versus none: OR = 1.422 (95% CI = 1.293; 1.565), and four voids/night versus none: OR = 1.575 (95% CI = 1.394; 1.781). The strength of the association was enhanced in patients over 64 years of age. CONCLUSIONS Nocturia is a strong independent predictor of prevalent hypertension in OSA. This association exhibited a "dose-response" relationship beyond two voids/night. The resolution of nocturia after continuous positive airway pressure (CPAP) treatment might be an important outcome to consider for the response of hypertension to CPAP.

Abstract
INTRODUCTION The aim of this study was to identify, from an hospital point of view, the care pathways of patients with chronic obstructive pulmonary disease (COPD) between the ambulatory and in-hospital settings in two regions to the East of Paris (Val-de-Marne and Seine-et-Marne). METHODS A qualitative multisite case study was conducted from January to October 2012 with hospital doctors managing patients with COPD. Semi-structured individual interviews were carried out with 46 hospital practitioners from the 25 main hospitals of this area. RESULTS A marked variability in care pathways was observed between the 25sites studied, but no typology could be established. The care pathways depended on the configuration of the available local medical facilities. The main finding of this study was the global lack of coordination between ambulatory care and in-hospital care of patients before and after hospitalization. DISCUSSION The care pathways identified concerned the probably most severely ill patients who frequently attend hospital emergency rooms. The lack of pre-hospital coordination for the management of acute exacerbations resulted in a very high hospitalization rate. However, international studies have showed that a better management in an ambulatory care setting reduced significantly the hospitalization rates. The problem ofcoordination between ambulatory and in-hospital carefor optimizing of the care pathways remains unsolved in the territories studied here. This example of COPD care shows that a better management of patients with chronic diseases requires a restructuring of the local health care systems in France.

Abstract
INTRODUCTION Catheter-related infection by non-tuberculous mycobacteria is rare but difficult to diagnose and the treatment is not standardized. CASE REPORT A 64-year-old woman treated for lung cancer with intravenous chemotherapy developed an infection of her totally implanted perfusion device with Mycobacterium chelonae. The infection was cured after surgical removal of the device and treatment with oral clarithromycin. CONCLUSION Mycobacteria may infect vascular access devices. Rapid diagnosis of such infections allows early treatment.

Abstract
Pulmonary fibrosis (PF) is an uncommon manifestation observed in patients with antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV), particularly microscopic polyangiitis (MPA). While patients with PF associated with AAV seem to have a worse prognosis, these patients have been described only in case reports or small retrospective case series. In this retrospective multicenter study, we report the main features and long-term outcomes of patients with PF associated with AAV, fulfilling the American College of Rheumatology criteria and/or Chapel Hill definitions. Forty-nine patients (30 men [61%]; median age at diagnosis of AAV, 68 [interquartile range, 58-73] years) with PF associated with AAV were identified. Forty (81.6%) patients had MPA and 9 (18.4%) had granulomatosis with polyangiitis. The diagnosis of PF preceded the onset of vasculitis in 22 (45%) patients. Usual interstitial pneumonia was the main radiologic pattern (n = 18, 43%). ANCA were mostly of antimyeloperoxidase specificity (88%). All patients were treated with glucocorticoids as induction therapy, combined with cyclophosphamide (CYC) (n = 36, 73.5%) or rituximab (RTX) (n = 1, 2%). Factors associated with mortality included occurrence of chronic respiratory insufficiency (hazard ratio [HR], 7.44; 95% confidence interval [CI], 1.6-34.5; p = 0.003), induction therapy with glucocorticoids alone (HR, 2.94; CI, 1.05-8.33; p = 0.04), and initial weigh loss (HR, 2.83; CI, 1.05-7.65; p = 0.041). The 3-year survival rate in patients treated with glucocorticoids alone or combined with an immunosuppressant (CYC or RTX) as induction therapy was 64% (95% CI, 41-99) and 94% (95% CI, 86-100), respectively (p = 0.03). After a median follow-up of 48 months [interquartile range, 14-88 mo], 18 (37%) patients died, including 11 related to respiratory insufficiency. PF is a rare manifestation of AAV with a very poor prognosis. Induction therapy with CYC might improve the outcome.

Abstract
BACKGROUND In Europe, administration of an inhaled corticosteroid (ICS) combined with a long-acting β2 agonist is approved in chronic obstructive pulmonary disease (COPD) patients with a pre-bronchodilator FEV1 < 60% predicted normal, a history of repeated exacerbations, and who have significant symptoms despite regular bronchodilator therapy. Minimal data are available on the use of the fluticasone propionate/salmeterol xinafoate combination (FSC) in the real-life COPD setting and prescription compliance with the licensed specifications. METHODS A French observational study was performed to describe the COPD population prescribed with FSC, prescription modalities, and the coherence of prescription practices with the market authorized population. Data were collected for patients initiating FSC treatment (500 μg fluticasone propionate, 50 μg salmeterol, dry powder inhaler) prescribed by a general practitioner (GP) or a pulmonologist, using physician and patient questionnaires. RESULTS A total of 710 patients were included, 352 by GPs and 358 by pulmonologists. Mean age was over 60 years, and 70% of patients were male. More than half were retired, and overweight or obese. Approximately half were current smokers and one-third had cardiovascular comorbidities. According to both physician evaluation and GOLD 2006 classification, the majority of patients (>75%) had moderate to very severe COPD. Strict compliance by prescribing physicians with the market-approved population for dry powder inhaler SFC in COPD was low, notably in ICS-naïve patients; all three conditions were fulfilled in less than a quarter of patients with prior ICS and less than 7% of ICS-naïve patients. CONCLUSIONS Prescription of dry powder inhaler SFC by GPs and pulmonologists has very low conformity with the three conditions defining the licensed COPD population. Prescription practices need to be improved and systematic FEV1 evaluation for COPD diagnosis and treatment management should be emphasized.

Loss-of-function mutations in RSPH1 cause primary ciliary dyskinesia with central-complex and radial-spoke defects. Am J Hum Genet 2013; 93:561-70.

Abstract
Primary ciliary dyskinesia (PCD) is a rare autosomal-recessive respiratory disorder resulting from defects of motile cilia. Various axonemal ultrastructural phenotypes have been observed, including one with so-called central-complex (CC) defects, whose molecular basis remains unexplained in most cases. To identify genes involved in this phenotype, whose diagnosis can be particularly difficult to establish, we combined homozygosity mapping and whole-exome sequencing in a consanguineous individual with CC defects. This identified a nonsense mutation in RSPH1, a gene whose ortholog in Chlamydomonas reinhardtii encodes a radial-spoke (RS)-head protein and is mainly expressed in respiratory and testis cells. Subsequent analyses of RSPH1 identified biallelic mutations in 10 of 48 independent families affected by CC defects. These mutations include splicing defects, as demonstrated by the study of RSPH1 transcripts obtained from airway cells of affected individuals. Wild-type RSPH1 localizes within cilia of airway cells, but we were unable to detect it in an individual with RSPH1 loss-of-function mutations. High-speed-videomicroscopy analyses revealed the coexistence of different ciliary beating patterns-cilia with a normal beat frequency but abnormal motion alongside immotile cilia or cilia with a slowed beat frequency-in each individual. This study shows that this gene is mutated in 20.8% of individuals with CC defects, whose diagnosis could now be improved by molecular screening. RSPH1 mutations thus appear as a major etiology for this PCD phenotype, which in fact includes RS defects, thereby unveiling the importance of RSPH1 in the proper building of CCs and RSs in humans.

Abstract
Background Primary ciliary dyskinesia (PCD) is a rare congenital respiratory disorder characterized by abnormal ciliary motility leading to chronic airway infections. Qualitative evaluation of ciliary beat pattern based on digital high-speed videomicroscopy analysis has been proposed in the diagnosis process of PCD. Although this evaluation is easy in typical cases, it becomes difficult when ciliary beating is partially maintained. We postulated that a quantitative analysis of beat pattern would improve PCD diagnosis. We compared quantitative parameters with the qualitative evaluation of ciliary beat pattern in patients in whom the diagnosis of PCD was confirmed or excluded. Methods Nasal nitric oxide measurement, nasal brushings and biopsies were performed prospectively in 34 patients with suspected PCD. In combination with qualitative analysis, 12 quantitative parameters of ciliary beat pattern were determined on high-speed videomicroscopy recordings of beating ciliated edges. The combination of ciliary ultrastructural abnormalities on transmission electron microscopy analysis with low nasal nitric oxide levels was the “gold standard” used to establish the diagnosis of PCD. Results This “gold standard” excluded PCD in 15 patients (non-PCD patients), confirmed PCD in 10 patients (PCD patients) and was inconclusive in 9 patients. Among the 12 parameters, the distance traveled by the cilium tip weighted by the percentage of beating ciliated edges presented 96% sensitivity and 95% specificity. Qualitative evaluation and quantitative analysis were concordant in non-PCD patients. In 9/10 PCD patients, quantitative analysis was concordant with the “gold standard”, while the qualitative evaluation was discordant with the “gold standard” in 3/10 cases. Among the patients with an inconclusive “gold standard”, the use of quantitative parameters supported PCD diagnosis in 4/9 patients (confirmed by the identification of disease-causing mutations in one patient) and PCD exclusion in 2/9 patients. Conclusions When the beat pattern is normal or virtually immotile, the qualitative evaluation is adequate to study ciliary beating in patients suspected for PCD. However, when cilia are still beating but with moderate alterations (more than 40% of patients suspected for PCD), quantitative analysis is required to precise the diagnosis and can be proposed to select patients eligible for TEM.

Abstract
OBJECTIVES The hypothesis that asbestos exposure may have more specific associations with particular histological types of lung cancer remains controversial. The aim of this study was to analyze the relationships between asbestos exposure and pulmonary carcinoid tumors. METHODS A retrospective case-control study was conducted in 28 cases undergoing surgery for pulmonary carcinoid tumors and aged >40 years and in 56 controls with lung cancer of a different histological type, matched for gender and age, from 1994 to 1999, recruited in two hospitals in the region of Paris. Asbestos exposure was assessed via expertise of a standardized occupational questionnaire and mineralogical analysis of lung tissue, with quantification of asbestos bodies (AB). RESULTS Definite asbestos exposure was identified in 25% of cases and 14% of controls (ns). Cumulative asbestos exposure was significantly higher in cases than in controls (P < 0.05), and results of the quantification of AB tended to be higher in cases than in controls (24 and 9% had >1000 AB per gram dry lung tissue, respectively, P = 0.09). Mean cumulative smoking was lower in cases than in controls (P < 0.05). CONCLUSIONS This study argues in favor of a relationship between asbestos exposure and certain pulmonary carcinoid tumors.

Abstract
Several etiologies are involved in the pathogenesis of cavitating pulmonary disease including neoplastic, infectious or inflammatory processes. Another is pulmonary infarction associated with venous thromboembolism. The lung cavities tend to be located peripherally and are the result of pulmonary embolism. We report the case of a woman with chronic thromboembolic pulmonary hypertension (CTEPH), associated with familial thrombophilia, revealed by cavitating pulmonary infarcts. CTEPH is sometimes diagnosed during an episode of recurrent pulmonary embolism following previously unnoticed lesions. Thrombophilias such as isolated elevated factor VIII are risk factors for CTEPH.
