Abstract
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.

Abstract
Biological diagnosis of whooping cough is increasingly necessary to confirm respiratory tract infection. Indeed, clinical symptoms are variable especially in adolescents and adults who contaminate newborns too young to be vaccinated. The PCR assay was proven highly sensitive for the diagnosis of pertussis. In this study, we reported the use of a new test (GenoQuick Bordetella [GQB], Hain Life Science, Germany) which permits the fast molecular genetic identification of Bordetella pertussis and parapertussis directly from patients specimens, i.e. swabs from nose or throat. The test was performed over a three months period on 40 specimens from patients (1 month to 65 years old), most of them were young children admitted in paediatric emergency with paroxysmal cough or prolonged cough.

Abstract
Classical collapse therapy with extrapleural Lucite balls placement used for tuberculosis sequelae is associated with long term complications, such as migration of the foreign body. We report a new modality of collapse therapy for tuberculosis cavitation which may avoid this complication and which uses percutaneous tissue expanders. Postoperative course was uneventful and mid term follow-up confirmed the functional improvement without recurrence of the infection. This new modality of post-tuberculosis collapse therapy may allow treatment with fewer physical and physiologic sequelae of the residual cavities, and should reduce long term complications such as migration.

Abstract
Evaporation of fluid at micro and nanometer scale may be used to self-assemble nanometre-sized particles in suspension. Evaporating process can be used to gently control flow in micro and nanofluidics, thus providing a potential mean to design a fine pattern onto a surface or to functionalize a nanoprobe tip. In this paper, we present an original experimental approach to explore this open and rather virgin domain. We use an oscillating tip at an air liquid interface with a controlled dipping depth of the tip within the range of the micrometer. Also, very small dipping depths of a few ten nanometers were achieved with multi walls carbon nanotubes glued at the tip apex. The liquid is an aqueous solution of functionalized nanoparticles diluted in water. Evaporation of water is the driving force determining the arrangement of nanoparticles on the tip. The results show various nanoparticles deposition patterns, from which the deposits can be classified in two categories. The type of deposit is shown to be strongly dependent on whether or not the triple line is pinned and of the peptide coating of the gold nanoparticle. In order to assess the classification, companion dynamical studies of nanomeniscus and related dissipation processes involved with thinning effects are presented.

Abstract
Whole-body positron emission tomography (PET) with radiolabeled [18F]-fluoro-2-deoxy-D-glucose (18FDG) plays an important role in the diagnosis, staging, and management of lung cancer. The preferential accumulation of FDG in malignant cells assists in the differentiation of benign and malignant tissue. However, PET alone does not allow an accurate anatomic localisation of FDG uptake. The combination of PET with CT images improves the spatial resolution, sensitivity and specificity of the test. PET/CT, as with PET alone, is indicated for the diagnosis of pulmonary nodules as well as the locoregional and extrathoracic staging of non-small-cell lung cancer (NSCLC). In many published studies, PET/CT has been shown to be superior to CT alone, to PET alone, or to both imaging techniques used separately to evaluate pulmonary nodules or for staging NSCLC. Now, PET/CT imaging is being investigated in the staging and management of small-cell lung cancer, in radiation treatment planning, in response prediction following treatment and in the detection of lung cancer recurrence in NSCLC. PET/CT is likely to have an important role in the management of lung cancer. New machines are in development and new radiopharmaceutical agents must be assessed.

Abstract
The dynamical behavior of a nanomeniscus is investigated with a oscillating nanoneedle recording information on the change of the shape and viscous contribution. At the air-glycerol interface, the dynamical properties exhibit a nonlinear behavior making the nanomeniscus evolution similar to a first-order phase transition. Also shown is the capability to record height images of the liquid interface with resolutions at nanometer scale. At the air-water interface, evaporation leads to more complex dynamical properties. The viscous damping first increases as a consequence of a thinning effect, then, when the contact angle reaches zero, the nanomeniscus is unable to sustain the dissipation.

Abstract
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.

Abstract
Nowadays acute limb ischemia (ALI) is still a tremendous complication that may compromise local or general prognosis. Every practician might be able to diagnose this situation in order to transfer in emergency the patient in a vascular unit. The main determinants of outcome of the leg are the severity of the ALI and a prompt treatment. The severity is evaluated according the SCV/ISCVS classification. Patients with a sensitive-motor neurologic deficit are at high risk; they require urgent therapy. The main causes are embolism and thrombosis. In case of classical presentation of embolism, immediate embolectomy will be done under local anesthetic. But this presentation is rare; often the picture is much more complex; the majority of ALI patients are elderly with atherosclerotic vessels. In such situation a team approach is mandatory to decide optimal management. The treatment may combine thrombolytic therapy or aspiration thrombectomy and percutaneous or surgical revascularisation. Finally, atrial fibrillation is now the most common cause of embolism, and appropriate anticoagulation would prevent this complication.

Abstract
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.

Abstract
OBJECTIVES We assessed the usefulness of fast-track neck sonography with a new-generation hand-held ultrasound scanner in the detection of > or =60% carotid stenosis. DESIGN Patients with a past history of atherosclerotic disease or presence of risk factors were enrolled. All had fast-track carotid screening with a hand-held ultrasound scanner. METHODS Initial assessment was performed with our quick imaging protocol. A second examiner performed a conventional complete carotid duplex as gold-standard. RESULTS We enrolled 197 consecutive patients with a mean age of 67 years (range 35-94). A carotid stenosis >60% was detected in 13 cases (6%). The sensitivity, specificity, positive and negative predictive value of fast-track sonography was 100%, 64%, 17% and 100%, respectively. Concomitant power Doppler imaging during the fast-track method did not improve accuracy. CONCLUSIONS The use of a fast-track method with a hand-held ultrasound device can reduce the number of unnecessary carotid Duplex and enhance the screening efficiency without missing significant carotid stenoses.

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
This report describes the case of a 37-year-old man who fell from 6 m height and presented an isolated rupture of the right pulmonary vein. The patient had a low blood pressure without any sign of intrathoracic injury. An echocardiogram revealed a tamponade with hemodynamic intolerance. The repair was made using cardiopulmonary bypass which made the inspection and total repair of the lesions easier. This case is unusual because of the isolated lesion and the few articles about similar reports founded in an extended literature review. Mechanisms and generation of blunt chest trauma lesions are discussed.

Abstract
Platelet-activating factor (PAF) is a lipid mediator that stimulates the in vitro growth of various human tumour cell lines and that enhances the effect of vascular endothelial growth factor that plays a key role during angiogenesis of human cancer. In this study, we assessed the levels of PAF and of the acetylhydrolase activity (AHA, the PAF degrading enzyme) in patients with lung cancer. Results indicated no significant differences between blood PAF amounts of lung cancer patients (91+/-33 pg/ml, n=31) and a control group of patients with chronic obstructive pulmonary disease (COPD) induced by habitual smoking (117+/-28 pg/ml, n=10). Similarly, their serum AHA levels were not different (67.9+/-3.0 nmol/min/ml as compared to 68.3+/-5.2 nmol/min/ml for lung cancer patients and controls, respectively). In contrast, PAF amounts were markedly (P=0.01, t-test for paired data) reduced in the lung tumour tissues (77+/-29 pg/g, n=10) as compared to the non-tumour tissues (208+/-67 pg/g, n=10). These low levels of PAF were not related to a lower amounts of the lyso-PAF precursor but to an elevated (P=0.01, t-test for paired data) AHA in the tumour tissues (37.0+/-4.9 nmol/min/g, n=10) as compared to the non-tumour tissues (24.6+/-2.6 nmol/min/ml, n=10). Reverse transcriptase polymerase chain reaction experiments showed the presence of the PAF receptor (PAF-R) transcript 1 but not transcript 2 in blood mononuclear cells of lung cancer patients and COPD patients. Flow cytometry experiments did not highlight differences in the number and the distribution of PAF-R on their circulating leukocytes. In conclusion, this clinical study highlights no evidence for a potential important role of PAF during human lung cancer.

Abstract
Many studies have shown that the risk of experiencing a myocardial infarction (MI) is increased during the first hours of the morning. Sleep apnea syndrome (SAS) is associated with an enhanced adrenergic activity, prolonged a few hours after awakening. We aimed at assessing whether sleep breathing disorders could be a culprit for the morning excess rate of MI. We studied 40 middle-aged men admitted for an acute MI. An overnight polysomnographic study was performed 37.4 +/- 9.4 days after the MI. The prevalence of SAS was high (30%). The prevalence of SAS was significantly higher in patients with the MI onset during the morning. The circadian pattern was significantly different in patients with or without SAS: those with SAS presented an important peak of MI onset during the period between 06.00 and 11.59 h. None of them had their MI during the period between 24.00 and 05.59 h. This different nyctohemeral pattern underlines the potential role of sleep breathing disorders as a trigger of MI.
