[Smoking cessation in the pregnant woman: descriptive study in Limousin].

OBJECTIVE: Among obstetricians and midwives, estimate the percentage of smokers, appraise the proportion of medical professionals who mention the subject of nicotine addiction to their pregnant patients, and assess the quality of the information delivered to patients as well as their own experience in the field of tobacology. PATIENTS AND METHODS: Between February and March 2002, 188 postal questionnaires were sent to obstetricians and gynecologists, midwives and midwife students of public hospitals in Limousin and private clinics in Limoges. RESULTS: The response rate was 75,5% (142 answers) and the median age was 37 years old (20-59). 43,6% of the respondents were current smokers. Patients' smoking habits would be asked for and the risks of tobacco smoking would be explained by the majority of praticians and midwives. Minimal counsel to be given was known and given by 34,4% of gynecologists an 26,5% of midwives. Smoking cessation counselling was never proposed by 62% of gynecologists and 79% of midwives. Seventy per cent of them did not have any specific training in the field of tobacology during their studies. DISCUSSION AND CONCLUSION: There seems to be a deficiency in smoking cessation help for pregnant women in Limousin. Specifics programs and trainings for obstetricians, gynecologists, as well as midwives should be organized.

[Pleural metastases of sclerosing epithelioid fibrosarcoma].

Sclerosing epithelioid fibrosarcoma is a rare tumor recently described. The histological presentation can be confused with certain soft tissue benign tumors and certain sarcomas. Metastatic spread is usually late in the natural course of the disease. We report a case of recurrent sclerosing epithelioid fibrosarcoma with pleural metastases which developed ten years after surgical resection of the primary tumor. The tumor was formed by small uniform round epithelioid cells with a clear cytoplasm. The tumor cells were strongly positive for vimentin. This clinical case is discussed in light of other cases reported in the literature.

[Economic analysis of home based versus hospital outpatient chemotherapy in stage IV non small cell lung cancer].

BACKGROUND: French law and government decisions have induced new development for home base treatments. The objective was to compare cost of home base chemotherapy (HBC) versus outpatient infusions, for non small cell lung cancer (NSCLC). METHODS: 10 patients were selected in each category. D8 of their cycles was performed at home compared to outpatient infusion. Costs were based on national fees with cytostatic drugs as supplement. The real cost was also assessed through a specific questionnaire. RESULTS: 30 D8 infusions were carried out at hospital and 24 D8 infusions at home. Average cost by cycle was 2,829.51 euros [2 560.74-3 147.02] for hospital infusion, 2,372.50 euros [1 962.75-2 792.88] for HBC (-16.15%). Difference was -457.01 euros by cycle [-919.74; 26.82]. Real costs by injection for BHC was 484.42 euros [424.18; 540.32] versus a fee of 699.89 euros [643.64; 750.23]. There were no difference in terms of adverse events. CONCLUSION: HBC for NSCLC is feasible. Average costs by cycle is lower of 16% versus hospital infusion. The results of this non randomized study had to be confirm by further clinical trials.

[Feasibility of administering Tegeline at home. Retrospective study of efficacy, safety and tolerance].

OBJECTIVE: To demonstrate the feasibility of administration Tegeline at home from a point of view of efficacy, safety, tolerance, to validate the pertinence of the selection and the training of patients who could benefit from this type of administration and to assess the long term efficacy and safety. METHOD: This retrospective study was conducted in patients exhibiting primary immune deficiency and formerly treated with intravenous immunoglobulins at least six months in hospital settings, trained by the centre for the training of children in the home (Centre de formation au traitement à domicile de l'enfant--CFTDE) and having received at least one administration of Tegeline at home from January 1st 2000. Tegeline contains a mean of 97.6% of whole IgG (58.8% of IgG1, 34.1% of IgG2, 5.4% of IgG3 and 1.7% of IgG4). RESULTS: Two hundred and eighteen follow-up sheets were completed by 13 patients in whom all the eligibility criteria were fulfilled. The total number of infusions per patient ranged from 4 to 41. No difficulty in administration was reported in 10 patients, difficulties in placing the needle were encountered in 3 other patients and motivating their return to the hospital for treatment (after 6 and 10 months) in 2 cases. The infusion flow rate was usually of 2 to 3 ml/kg/h. During the follow-up period, no episode of infection was noted in 5 patients and 8 presented infections that were treated with antibiotics. Regarding safety, the security 'kits' (corticosteroids, adrenalin) that were supplied to each patient were never used. Over time, the median duration of the infusions at home was of 5 years and 6 months. CONCLUSION: In trained and selected patients, this study demonstrated the efficacy, safety and tolerance to the administration of Tegeline at home.

Assessment of 18F-fluorodeoxyglucose dual-head gamma camera in asbestos lung diseases.

The purpose of this study was to evaluate the performance of 18F-fluorodeoxyglucose (18FDG) imaging via coincidence detection emission tomography (CDET) in identifying malignant lesions in subjects exposed to asbestos. A total of 30 patients exposed to asbestos underwent 18FDG-CDET between January 2000 and June 2003. A CDET scan of the thorax and abdomen was performed 60 min after injection of 18FDG in fasting patients, and results were obtained in slices in three axes. The CDET results were compared to those from computed tomography (CT), and pleural or surgical biopsy in patients with positive 18FDG-CDET results. All primary malignant mesotheliomas accumulated 18FDG (n=6), and, in two patients, CDET findings were superior to those of CT, allowing early detection. In two cases, lung carcinomas with malignant pleural effusion were also detected. There were five false positive CDET results: three unilateral pleural thickening, one rounded atelectasis, and one benign lung nodule. All patients with pleural plaques showed no significant 18FDG uptake. Malignant diseases were detected by 18FDG-CDET imaging with a sensitivity of 89% and specificity of 71%. Coincidence detection emission tomography can identify malignant mesothelioma in selected subjects exposed to asbestos. Coincidence detection emission tomography appears to be a useful noninvasive method for the follow-up of subjects with exposure risk of asbestosis.

[Respiratory effects of risperidone? A prospective study].

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).

[Clinical and biological surveillance after the cessation of Hymenoptera venom desensitization].

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.

AAV2 vectors mediate efficient and sustained transduction of rat embryonic ventral mesencephalon.

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.

[Severe interstitial pneumonitis related to Gemcitabine].

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.

[Prevalence of exercise-induced asthma in school children].

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.

[Pseudoneoplastic forms of bronchiolitis obliterans with organizing pneumopathy (BOOP)].

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.

[Value of 18FDG-CDET in the evaluation of operable bronchial cancer].

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.

[Radon and domestic exposure].

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.
