[The Lady Windermere syndrome: clinical and bacteriological data and progress in seven cases]. / Le syndrome de Lady Windermere : données cliniques, bactériologiques et évolutives.

Described by Reich and Johnson in 1992 [2], the Lady Windermere syndrome occurs exclusively in non-smoking women over the age of 60 years, without significant pre-existing pulmonary disease. It comprises bronchial dilatation, typically in the middle lobe and lingula, together with secondary infection by atypical mycobacteria (Mycobacterium avium in the first cases). Among the 17 cases of atypical mycobacterial infection that we have seen in the past 14 years, there were seven cases of this syndrome. It was associated with cough, sputum, sometimes haemoptysis, febrile episodes and deterioration of general health. The diagnostic criteria and treatment were defined by the American Thoracic Society. The pathophysiological hypothesis proposed by Reich and Johnson was that voluntary suppression of the cough led to congestion of the bronchi and secondary infection with atypical mycobacteria. Currently it is thought more likely that the following factors are involved: progressive increase in dilatation of small bronchi, delayed diagnosis, morphological abnormalities of the thorax, hormonal factors, immune deficiency, genetic neutrophil dysfunction, and even heterozygous forms of cystic fibrosis.

Randomized follow-up study of resected NSCLC patients: conventional versus 18F-DG coincidence imaging.

The aim of this study was to compare the utility of gamma camera using a coincidence detection system imaging (CDET) with 18-fluorodeoxyglucose to conventional imaging techniques in the detection of recurrence of non-small cell lung cancer. Sixty-nine patients were randomized into two groups for follow-up after surgery from October 2000 to December 2002. Each patient was evaluated every 6 months by conventional technique imaging in group A (n=33) or CDET imaging in group B (n=36) over two years. The direct costs of each procedure were evaluated. The major endpoint was the number of recurrences or new tumours detected. The two groups were similar. A total of 25 recurrences was detected (9 in group A and 16 in group B). Overall survival was similar in the two groups. CDET imaging was more expensive. CDET imaging provides earlier detection of recurrence, but does not modify survival outcome. Further studies are necessary to demonstrate the impact, if any, of 18-FDG imaging.

[Age and management decisions in patients with primary lung cancer]. / Age et décision de prise en charge des patients atteints d'un cancer pulmonaire primitif.

INTRODUCTION: Therapeutic decisions are difficult in elderly patients because of the heterogeneity of this population. Our objective was to evaluate the role of age in the management of patients suffering from primary lung cancer seen in the department of respiratory diseases of the Limoges regional teaching hospital between 2002 and 2004. METHODS: A cross sectional study analysed the management of 363 patients suffering from primary lung cancer. The patients were divided into two groups according to their age (less than seventy or seventy and over). A comparison was made between the management of the two groups. RESULTS: The comparisons according to age produced evidence of reduced activity, greater dependence, an increased Charlson score, less frequently administered radiotherapy and chemotherapy, and more frequent symptomatic treatment in the elderly group (p<0.001). CONCLUSIONS: The geriatric assessment of patients suffering from primary lung cancer should make allowance for the physiological age of the patient and adapt the management to ensure the best quality of life.

Use of both CD63 up regulation and IgE down regulation for the flow cytometric analysis of allergen induced basophil activation. Definition of an activation index.

OBJECTIVE AND DESIGN: The aim of this study was to compare the use of a late (CD63) and an early (IgE) marker of basophil activation in the flow cytometric diagnosis of beta-lactam induced allergic hypersensitivity reactions. SUBJECTS: Twelve patients who had had a clear cut betalactam induced immediate reaction and 16 controls were selected, as well as 11 patients who had had an immediate reaction to bee or wasp stings. METHODS: Leukocyte suspensions were incubated with allergen dilutions as well as 2 positive controls (anti-IgE and NFormyl- Methionyl-Leucyl-Phenylalanine (fMLP)). Basophils were labelled with an anti-IgE FITC (fluorescein isothiocyanate) and an anti-CD63 PE (phycoerythrin). Results were expressed as percentage CD63 expression and index calculated according to a specific algorithm including the two activation markers. RESULTS: Significant CD63 expression (>5 %) was observed in 3/12 cases for the beta-lactam sensitized population, in 0/16 cases for the controls and in 11/11 cases for the venom sensitized population. A significant index (determined by a ROC analysis) was observed in 11/12 beta-lactam sensitized patients and in 0/16 controls. CONCLUSION: These results show that IgE (an early activation marker) is more sensitive than CD63 (a later activation marker) in the diagnosis of beta-lactam allergy.

Survival of Listeria monocytogenes and Enterococcus faecium in sludge evaluated by real-time PCR and culture methods.

AIMS: This study evaluates the behaviour in spiked sludge of a pathogenic bacteria, Listeria monocytogenes, by cultural and molecular techniques, and compares its survival with the one of a faecal indicator, Enterococcus faecium. METHODS AND RESULTS: Listeria monocytogenes strain Scott A and E. faecium(T) were followed for 17 days after inoculation in sludge. Kinetics of survival depended on the bacteria and on the technique used [most probable number method, direct plate count or real-time quantitative PCR (qPCR)]. The concentration of L. monocytogenes decreased rapidly regardless of the technique, but the decrease was much more dramatic with culture techniques than with qPCR. On the contrary, the concentrations of culturable E. faecium(T) were stable. CONCLUSIONS: The results suggest that the cells of L. monocytogenes strain Scott A might have entered a viable, but nonculturable (VBNC) status, whereas cells of the indicator bacteria, E. faecium(T), maintained themselves better and stayed culturable. SIGNIFICANCE AND IMPACT OF THE STUDY: The difference of survival kinetics in the sludge of a faecal indicator (E. faecium) and a pathogenic bacterium (L. monocytogenes) may be linked to the fact that they either enter or do not enter into a VBNC status.

[Pleural metastases of sclerosing epithelioid fibrosarcoma]. / Métastases pleurales d'un fibrosarcome épithélioïde sclérosant.

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]. / Analyse économique de l'administration d'une chimiothérapie en hospitalisation à domicile (HAD) comparée à l'hospitalisation de jour dans les cancers bronchopulmonaires non à petites cellules de stade IV.

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.

[Smoking cessation in the pregnant woman: descriptive study in Limousin]. / Sevrage tabagique chez la femme enceinte : étude descriptive en 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.

[Investigation of allergic reactions to platinum salts]. / Exploration d'une allergie aux sels de platine.

INTRODUCTION: We report two cases occurring in 2004 of patients being treated for pleural mesothelioma with a combination of cisplatin or carboplatin and pemetrexed. Investigation by skin tests and flow cytometry confirmed the clinical diagnosis in both cases. CASE REPORTS: Case 1: a man of 62 developed, after 12 courses of cisplatin-pemetrexed, an anaphylactic reaction 5 minutes after the infusion of cisplatin. Treatment was withdrawn permanently. Case 2: a man of 66 developed, after 7 courses of cisplatin-pemetrexed, an anaphylactic reaction within the first minute of the infusion of cisplatin. Subsequently, in March 2004, he received pemetrexed alone without any problems. In August 2004 he was prescribed carboplatin-pemetrexed. Within 5 minutes he developed urticaria, pruritus and abdominal pain. He was treated later with pemetrexed alone with no problems. CONCLUSION: Hypersensitivity to platinum salts usually occurs after several courses of treatment. Skin tests and flow cytometry are a simple, concordant, and reliable way of confirming the diagnosis.

Aspirin and non steroidal anti-inflammatory drugs hypersensitivity review (2002-2004).

According to physician, Aspirin and NSAIDS hypersensitivity are causing three major problems: how to make the diagnosis? Which treatment are to he given to these patients? What kind of anti-inflammatory drugs are to be prescribed? For these last three years, several articles regarding these matters were being published.

Decrease of enteric micro-organisms from rural sewage sludge during their composting in straw mixture.

AIMS: To study the decrease of enteric micro-organisms including viable nematode eggs, enteroviruses, faecal indicators (Escherichia coli and enterococci) and pathogenic bacteria (Listeria monocytogenes, Salmonella sp. and Clostridium perfringens) of a rural sewage sludge when it is composted for 7 months in mixture with straw. METHODS AND RESULTS: Numbers of the test organisms and the physico-chemical parameters were measured on a monthly basis on the mixture, on the compost after being turned, and on the pile in three positions representing the part by which air is incoming, the bottom of the pile and the part through which air is outgoing. The lowest temperature in the pile was observed at the bottom, where it did not exceed 50 degrees C against 66 degrees C in the two other areas. There were no significant differences between the three areas in terms of micro-organism survival. Infectious enteroviruses were inactivated rapidly and were not found after the first turning whereas some genomes were detected until after the third turning. Escherichia coli and enterococci presented a similar survival rate and their number decreased by 4 log(10) whereas Salmonella decayed at a greater rate than L. monocytogenes. The numbers of C. perfringens decreased gradually to reach a final concentration in the mature compost of about 10(2) CFU g(-1) dry matter (d.m.), which was similar to that of the faecal indicators. CONCLUSIONS: The hygienic effect of sludge composting in mixture with straw results in a significant reduction of enteric micro-organisms, the concentration of the faecal indicators in the final product being < 64 most probable number g(-1) d.m. The concentrations of Salmonella, enteroviruses and viable nematode eggs in the final product were not detectable which is in accordance with the French legislation. SIGNIFICANCE AND IMPACT OF THE STUDY: The results which pointed out the different behaviour of the test micro-organisms reflect the difficulty to propose a relevant indicator of hygienization. Otherwise, they show that composting is an efficient means for hygienization of sludge of rural wastewater treatment, where the straw is available close to their place of production.

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.

[Feasibility of administering Tegeline at home. Retrospective study of efficacy, safety and tolerance]. / Faisabilité de la substitution à domicile par Tégéline. Etude rétrospective sur des données d'efficacité de sécurité et de tolérance.

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.

[Respiratory effects of risperidone? A prospective study]. / Effets respiratoires de la rispéridone? Etude prospective.

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).

Occurrence of Listeria sp and L monocytogenes in sewage sludge used for land application: effect of dewatering, liming and storage in tank on survival of Listeria species.

The application of sewage sludge to agricultural land is widely used in France. To determine the impact of sludge treatments, concentrations of Listeria sp., Listeria monocytogenes and faecal indicators were monitored in five types of sludge from three sewage treatment plants in Angers (France) and its suburbs over a 1-year period. On the whole, bacteria were reduced in numbers through sludge treatments. Apart from liming, which leads to reduced levels of bacteria below detection limits, other sludge treatments did not eliminate Listeria sp. and faecal indicators. Listeria sp. and L. monocytogenes were found respectively in 87% and 73% of dewatered sludges and in 96% and 80% of sludges stored in tanks. Concentrations of L. monocytogenes, ranging from 0.15 to 20 MPN g(-1) dry matter in dewatered sludge and from 1 to 240 MPN g(-1) dry matter in sludge stored in tanks, did not show seasonal variations. Spreading of sanitised sludge onto agricultural land results in the addition of 10(6)-10(8) L. monocytogenes per hectare per year, which may contribute to the increase in the dissemination of this pathogenic species in the environment.
