Abstract
107 patients have discontinued Hymenoptera venom immunotherapy between 1988 and 2000. 31 have been seen again with intradermal tests with IgEs, and 81 responded to a questionnaire. Intradermal reactions and IgEs decrease together significantly during immunotherapy and then persist at low level during three years. Beyond, the number of patients is insufficient. 32 patients were stung by the same Hymenoptera and not had any systemic reaction. However, five have beta blockers, three have IEC and half of the patients don't take precautions to avoid Hymenoptera.

Abstract
Pets must be considered allergy factors. They are not advised for atopic families. However some recent publications suggest a protective effect of cat and dog exposure in the first year of life. The origin of this protective effect is not known.

Abstract
Risperidone is an atypical neuroleptic which has been incriminated as a cause of respiratory symptoms. The purpose of this prospective study was to assess over a three-month period the respiratory status of patients free of allergic or respiratory disease treated with risperidone. Thirty-nine patients were enrolled. Twenty dropped out. One patient developed cough very likely related to risperidone but with no change in function. Bronchial hyperreactivity developed in two other patients who had no clinical symptom or sign of respiratory disorder. Despite the small number of patients in this study, risperidone would appear to have secondary respiratory effects. The high frequency of bronchial hyperreactivity observed in patients at inclusin and the nearly constant co-prescription of other psychiatric drugs suggests a potential combination effect (notably with selective seritonin reuptake inhibitors).

Abstract
BACKGROUND Although asthma is the most common pulmonary condition in pediatrics, the incidence of exercise-induced asthma (EIA) in school children is not well documented and few studies have been devoted to the condition. There are considerable variations in morbidity and mortality between countries. This study was designed to evaluate the prevalence of EIA in children in the 6th grade (11-14 year-olds) in one French department (Haute-Vienne) and to identify undiagnosed cases. METHODS The representative sample was obtained over a period of 28 days (February 2(nd) to April 10(th) 1998) by cluster sampling method, stratified by size of the schools. The number of subjects planned was 891. The selected children filled in a questionnaire on their asthma history and were subjected to an outdoor exercise test (6 minute run). Respiratory function was measured with a peak flow-meter. RESULTS Seven hundred and eighty two school children were included in this survey. Participation rate was 87.8%. The prevalence of asthma from the questionnaire was 10.7% (CI 95%: 8.7 - 12.8). After exercise, 68 school children presented exercise-induced bronchospasm: the prevalence of the EIA was 8.7% (CI 95%: 6.9 - 10.5). Among these 68 school children, 27 were known asthmatics and 41 were not. With the 10 treated asthmatics, the overall prevalence of EIA was therefore estimated at 9.9% (CI 95%: 8.2 - 11.7). CONCLUSION The prevalence of asthma and EIA was close to that found in other studies using a similar methodology. EIA remains under-diagnosed since 41 undeclared asthmatic school children were identified in our population. Nurses'information is necessary to initiate the use of systematically testing respiratory function (with a peak flow meter) at least once a year. Efficient management of the asthmatic child requires cooperation between the various professionals dealing with school children.

Abstract
Gemcitabine is used to treat solid tumours such as non small-cell lung cancer. In general, it is a well tolerated cytotoxic agent and myelosuppression is the major dose limiting side-effect. Pulmonary toxicity has been described and dyspnoea occurs in approximately 8% of patients in whom, for the majority, it is mild and reversible. But several cases of acute respiratory distress syndrome (ARDS) related to Gemcitabine treatment have been reported since 1997 and a few were fatal. We present a case of Gemcitabine toxicity in a patient treated for a lung cancer. He presented with a respiratory distress syndrome due to acute interstitial pneumonitis from which he promptly recovered with corticosteroid therapy.

Abstract
The success of transplantation of human embryonic mesencephalic tissue to treat parkinsonian patients is limited by the poor survival of the transplant. We show that an AAV2 vector mediates efficient expression of the egfp reporter gene in organotypic cultures of freshly explanted solid fragments of rat embryonic ventral mesencephalon (VM). We observed early and sustained transgene expression (4 days to > or = 6 weeks). Furthermore, rAAV-infected rat embryonic VM transplanted in the adult striatum continued to express EGFP for > or = 3 months. More than 95% of the transduced cells were neurons. Dopaminergic neurons were transduced at low frequency at earlier time points. This method of gene delivery could prove useful to achieve local, continuous secretion of neurotrophic factors at physiologically relevant doses to treat Parkinson's disease.

Abstract
The purpose of this study was to investigate the utility of 18fluorodeoxyglucose (FDG) coincidence detection position emission tomography (CDET) in the evaluation of metastatic mediastinal lymph nodes in patients with potentially operable non-small-cell lung cancer (NSCLC). A prospective study was performed in thirty patients with newly suspected NSCLC. Thoracic computed tomography (CT), FDG CDET, and invasive surgical staging were performed in patients. Blinded prospective interpretation was performed for each test and compared to pathological staging obtained by mediastinoscopy and/or by thoracotomy. Patients were followed for six months to detect occult metastases. The sensitivity and specificity of CDET for the detection of mediaStinal lymph nodes were 75% and 94.4% respectively. The corresponding value for CT were 50% and 80.9%. Three patients with N1 disease were classified as N0 by CDET. With regard to definitive surgical node staging, CDET could identify nodal disease in 26 patients and CT only in 18 patients (n = 30). FDG full-ring positron emission tomography (PET) is the most accurate non-invasive method for the detection and staging of lung cancer. In addition, FDG CDET shows high accuracy for the detectability of pulmonary lesions with a diameter at least 2 cm and the evaluation of lymph node in NSCLC.

Abstract
Chronic obstructive bronchiolitis with organizing lung disease is an anatomoradioclinical entity characterized by nonspecific inflammation associated with recurrent migratory minimally dense alveolar opacities on the chest x-ray poorly responsive to corticosteroid therapy. Excepting this typical presentation, other clinical forms may occur. We report the cases of two patients with an exceptional localized presentation raising the differential diagnosis of lung cancer.

Abstract
Radon is a noble gas derived from the decay of radium, which itself is a decay product of uranium. The decay products of radon can collect electrostatically on dust particles in the air and, if these particles are inhaled and attach to bronchial epithelium, produce a high local radiation dose. Alpha particles can induce DNA double-strand breaks and the development of cancer. A causal relation between lung cancer and radon exposure and its progeny has been demonstrated in epidemiological studies of miners. Radon exposure became a public health issue almost 15 years ago. Most radon exposure occurs indoors, predominantly in the home. There is however, a wide range of radon concentration values in different countries. The highest level occurs in areas with granite and permeable soils. The risk for smoking, the leading cause of lung cancer, is far greater than for radon, the second leading cause. The estimates obtained from case-control studies of indoor radon are very contradictory. Scientific knowledge of effects of low levels of exposure to radon and the role of cigarette smoking, as a combined factor, must be studied. Smoking and radon probably interact in a multiplicative fashion.

Abstract
Renal metastasis from carcinoma of the lung is rarely a clinical problem. Autopsic series however prove that the kidney is a frequent metastatic organ (20%). We report the case of a 43-years-old male patient affected with a squamous cell carcinoma of the lung, with bilateral renal extension. These secondary localizations were detected through a left flank pain prior to a systemic inflammatory response syndrome. The absence of hematuria (even microscopic) contrasted with the importance of the lesions. The age, along with the poor general state of our patient and the absence of any CT specificity justified an exploratory lobotomy. The pathologic analysis of the renal biopsies confirmed the metastatic nature of the lesion.

Abstract
A Phase I trial of carboplatin therapy was performed on patients with locally advanced non-small cell lung cancer who had been previously treated with cisplatin, mitomycin and a vinca aklaloïd. This was administered as a daily bolus infusion or as a continuous infusion for 6 weeks with concurrent daily thoracic radiation. All patients had to be objective responders or to show no change after chemotherapy. The carboplatin was started at 10 mg/m2 per day, and increased to 15 mg/m2 per day and 20 mg/m2 per day, if treatment was feasible in successive cohorts of at least six patients. The radiation therapy consisted of 62-66 Gray on the tumor and the ipsilateral mediastinal nodes, 50 Gray on the mediastinum and 40-45 Gray on the supraclavicular lymph nodes. Twenty-nine patients took part in this study. Thrombocytopenia was the principal dose-limiting toxicity, with 15 mg/m2 per day of bolus or continuous infusion. Other toxicities included a fall in haemoglobin level, a fall in white-blood cell count, nausea and vomiting. The median survival time was 12 months, but the response rate cannot be determined among patients selected on the basis of response to chemotherapy. The recommended Phase II dose for patients previously treated with cisplatin containing chemotherapy, is 10 mg/m2 per day of either a bolus or continuous infusion.

Abstract
The aim of this study was to assess the percentage of respiratory disorders and airway obstruction in patients with rheumatoid arthritis by comparing lung function test results between patients with rheumatoid arthritis and control subjects with other rheumatological conditions. A prospective case-control study of respiratory symptoms and lung function abnormalities was performed in a series of 100 patients with rheumatoid arthritis. Eighty eight patients with other rheumatological diseases served as controls. Diagnosis of respiratory disorders was based on clinical, radiological and spirometric findings. Airway obstruction was determined from predicted values. The results were compared using Student's t-test and Chi-squared tests. An explanatory analysis was carried out by linear regression. The number of symptoms, respiratory disorders (including bronchiectasis) and lung function abnormalities was higher in patients with rheumatoid arthritis than in controls. After exclusion of smokers, the proportion of airway obstruction in patients with rheumatoid arthritis was 16% (versus 0% in controls), although the patients with rheumatoid arthritis still had more symptoms and respiratory disorders. The Chi-squared test did not identify any relationship between airway obstruction, duration of rheumatoid arthritis and type of treatment and occurrence of Sjögren's syndrome. In the nonsmokers, different explanatory models for the patients with and without a history of cardiac and respiratory disease emerged from multivariate analysis of indices of obstruction. These models included variables characterizing the severity and course of the rheumatoid arthritis. Respiratory disorders (including bronchiectasis) and airway obstruction are more frequent among patients with rheumatoid arthritis than in rheumatological controls. Although the exact pathophysiology of the link between bronchial obstruction and rheumatoid arthritis is still a matter of debate, explanatory factors for obstruction included variables characterizing the rheumatoid arthritis.

Abstract
Glutathione (GSH) is one of the key components of the lung antioxidant defenses. Chronic smokers have higher GSH concentrations in their epithelial lining fluid than do nonsmokers. The aim of this study was to compare antioxidant concentrations in epithelial lining fluid (ELF) from nonsmokers, smokers with, and smokers without non-small-cell lung cancer. The study found that GSH in ELF from patients with lung cancer was significantly greater than in ELF from smokers and nonsmokers, at 1,485.5 +/- 208, 544 +/- 97.6 microM, and 339.3 +/- 112 microM, respectively (p < 0.05). In contrast, superoxide dismutase (SOD) was lower in ELF from patients with lung cancer than in that from smokers and nonsmokers, at 3.52 +/- 0.99, 30.82 +/- 8.2, and 43.91 +/- 10.1 U/ml, respectively (p < 0.05). Spontaneous superoxide anion release by adherent alveolar macrophages (AM) showed no difference between smokers with and without lung cancer. These data indicate that patients with lung cancer have marked modifications in their ELF antioxidant defenses by comparison with those of smokers. It is difficult to distinguish whether changed antioxidant status is a primary disturbance involved in the cancer process or whether it is a consequence of the neoplastic changes in malignancy.

Abstract
We report two cases of perindopril-associated pneumonitis with typical drug-induced clinical features. In the first case, biopsies showed granulomatous sarcoid-like lesions; in the second, bronchial wall eosinophil infiltratf2p4was reported with increased blood eosinophil count. In these two cases, improvement was obtained by withdrawal of the drug and was completed with steroids. All other causes were ruled out. Angiotensin-converting enzyme inhibitor (ACEI)-induced pneumonitis is still rare but has to be recognized as a real side-effect.

Abstract
The reappearance of tuberculosis in France, in Europe and throughout the world has rekindled interest not only in curative treatment of the disease but also in its prevention. Since its appearance in 1921, the BCG vaccine has been the subject of debate; however, recent studies have fully demonstrated its interest, particularly in countries where tuberculosis is most endemic. The technical aspects of the treatment have changed little and are essentially based on intrademic administration, but the impact of BCG, especially for individual protection, are discussed. Its role in protection of the general population and in prevention of tuberculosis requires careful analysis. Study of iatrogenic effects of the vaccine shows that its side effects are minor when recommendations for use are followed. With the development of molecular biology techniques and mycobacteria genetics, the future use of the BCG vaccine seems promising.

Abstract
BACKGROUND Utilization of diagnosis related groups (DRGs) for hospital comparison, based on length of stay (LOS). OBJECTIVES Inside a DRG (Pneumonia and pleurisy > 69 and/or associated comorbidities), to point out the explicative factors of LOS and the variables which could be recorded for a better description of these patients. SETTING Pneumologic unit of Limoges' teaching hospital. METHODS From 01-01-94 to 31-12-94, the DRG 129 was studied through the medical unit summary, the performance status at entrance, the social complexity, the characteristics of pneumonia (symptoms, temperature, arterial pressure...), the severity by American Thoracic Society (ATS) criteria, the procedures (chest X-ray, biology, fibroscopy...), the antibiotic treatments (intravenous and oral). Statistical tests associated univariate analysis, linear and logistic regressions. RESULTS LOS was 15.53 d +/- 8.57 (m +/- SD). The mathematical model explains 69% of the variance of LOS logarithm. The logistic regression found 5 variables with a significant odds-ratio (OR) for an increased LOS: a high ATS score, repeated laboratory tests, a complex social situation, an increase length of antibiotic treatment (intravenous and oral). CONCLUSION A better description of LOS, inside a DRG, needs supplementary variables. For pneumonia admitted in Limoges' hospital, the severity of the disease, the number of laboratory tests, the antibiotic treatment, the social complexity are the more significant indicators.

Abstract
OBJECTIVE To assess the prevalence of distal airway obstruction and its risk factors in agricultural areas. METHODS A cross sectional study of respiratory symptoms and lung function was performed among French farmers and their spouses (1122 subjects) who came for preventive medicine examinations. They answered a respiratory questionnaire and performed pulmonary function tests on a portable spirometer. Diagnoses of chronic bronchitis were made on the basis of reported chronic respiratory symptoms. Airway obstruction was determined from predicted values. Odds ratio (OR) and linear regression coefficients were calculated after stratification by smoking and history of cardiac and other respiratory diseases. RESULTS Of respiratory symptoms prevalence of chronic cough was 8.47%, and chronic bronchitis 7.66%. Prevalence of distal airway obstruction was 11.4%, and overall airflow obstruction 3.2%. Smokers were 20.2% men, and 5.7% women. Linear regressions showed high association between pack-years in smokers or exsmokers and forced expiratory volume in one second/forced vital capacity (FEV1/VC) and forced expiratory flow between 25% and 75% of vital capacity (FEF25-75). In non-smokers without any history of cardiac or respiratory diseases, age and the size of farms had the highest correlations with these variables. OR for distal airway obstruction was 2.1 in subjects > 50 years old v the younger ones and 3.02 in the smaller farms v the larger ones. CONCLUSION After stratification by smoking and history of cardiac and respiratory diseases, distal airway obstruction is present in agricultural areas. The age, and the size of farm are the highest respiratory risk factors in non-smokers.
