[Screening program for tuberculosis among international exchange students in the Department of Isère]. / Dépistage de la tuberculose chez les étudiants étrangers en échange international en Isère.

INTRODUCTION: France is a low-incidence country for tuberculosis (TB). Consequently screening is focused on high-risk populations, in particular migrants. The aim of this study was to evaluate the epidemiology of TB among international exchange students in the Department of Isère and the screening programs used. METHODS: We carried out an organizational audit based on interviews with physicians involved in the management of TB in Isère. We conducted a retrospective descriptive study based on a case series of foreign students treated for TB from 2003 to 2013 inclusively. RESULTS: Forty-six international exchange students were treated for active TB during this time, representing an average incidence of 284/100,000. Two thirds of our studied population were Africans, 72% were asymptomatic at the time of screening. A quarter of our cohort developed TB after the initial screening. Thirty-one cases were confirmed bacteriologically, mainly through bronchoscopy. Outcome (radiological and clinical) on quadruple therapy was satisfactory in all patients. Two patients relapsed, one of them with multi-drug resistant TB. CONCLUSION: Our work confirms that international exchange students are a population at high risk of TB and that screening of this population is essential. The significant number of active TB cases diagnosed after the initial screening stresses the importance of diagnosis and follow up of patients with latent TB infection.

[Tuberculosis control in France--evaluation of practice by a working group of the Société de Pneumologie de Langue Française]. / La lutte antituberculeuse en France: évaluation des pratiques par un groupe de travail de la SPLF auprès des services de lutte antituberculeuse.

INTRODUCTION: The management of tuberculosis has been the subject of renewed interest in France. Recently, the recommendations and the regulations concerning the disease have been updated. However, the resources that are actually available and the processes in place in different French departments are not clearly known. A national survey was thus carried out by a working group of the SPLF in charge of the recommendations concerning the medical, social and administrative management of the disease. METHODS: A questionnaire was sent to the 100 French departmental Antituberculous Services (SLAT). This explored the structures, activity, organisation involved, and difficulties encountered in Tuberculosis management. RESULTS: Ninety SLAT took part in the study. Their answers reveal: a discordance between a number of cases notified to the Department of Sanitation and Health (DDASS) and the number of cases known to the SLAT; a disparity between means involved in this study and the number of patients followed up as well as the choice of populations targeted for tracing); a willingness to deal with contact tracing although the investigations around individual cases and the definition of which subjects should be followed up were variable; a demand for protocols, networks and national recommendations. CONCLUSIONS: The SLAT are involved in the fight against tuberculosis with 20 years experience. The needs expressed in this survey point the way towards future prioritary actions to improve tuberculosis control nationally.

Sequential combination of 5-fluorouracil, cis-platinum and irradiation in unresectable non-small cell lung cancer.

Twenty patients with unresectable non-small cell lung carcinoma, 15 stage III and 5 stage IV (supraclavicular lymphadenopathy) were treated with a combination of three courses of chemotherapy and hypofractionated irradiation followed after 3 weeks by split-course radiotherapy. Each course was repeated every 3 weeks with the following sequence. Cis-platin (CDDP) (20 mg/m2) was given in a 20-min infusion, followed by a 2-h infusion of 5-fluorouracil (5-FU) (400 mg/m2) on days 1, 2, 5 and 6. Radiation with a dose of 3 Gy on the target volume was given on days 3 and 4, after a 2-h infusion of 5-FU (400 mg/m2). Split course of irradiation consisted of 16 Gy in 5 fractions repeated after 3 weeks interval. The objective response rate was 75%. Median follow-up was 24 months, the median survival was 14 months. The 1-year survival was 53% and the 2-year survival was 16%.

Primary pulmonary lymphomas. A clinical study of 70 cases in nonimmunocompromised patients.

We studied 70 patients with biopsy-proven pulmonary non-Hodgkin's lymphomas without extrathoracic involvement or mediastinal adenopathy to determine the clinical, imaging, and endoscopic features of this condition in a homogeneous series. In low-grade (LG) lymphomas, symptoms were cough, dyspnea, chest pain, hemoptysis. Imaging features consisted of localized alveolar opacities, infiltrative diffuse opacities, atelectasis, and pleural effusions. Inflammatory changes of the mucosa were present in some patients, leading to bronchial stenosis in 7; biopsies showed lymphomatous infiltration in 12. Prognosis of LG lymphomas was excellent, with 93.6 percent survival at five years. High-grade lymphomas differed from LG lymphomas principally by a more aggressive course and a worse survival. Inflammatory changes occurred in seven of nine cases leading to stenosis in two, and biopsies showed lymphomatous involvement in five. The profile of primary pulmonary lymphomas in this study could help clinicians consider this condition and prompt them to evaluate new diagnostic tools.

Double-lung transplantation using donor lungs with a right tracheal bronchus.

A 58-year-old man underwent sequential bilateral lung transplantation. On the donor heart-lung block, it was discovered that the right apical segment was supplied by a tracheal bronchus. After the separate implantation of both lungs, a right apical segmentectomy was performed and the postoperative course was uneventful. The management of this problem is discussed.

[Chemotherapy of small-cell lung cancer by a combination of teniposide, ifosfamide and carboplatin]. / Chimiothérapie du cancer bronchique à petites cellules par une association de téniposide, ifosfamide et carboplatine.

Thirty six SLC patients have been treated with a combination therapy of ifosfamide 2 g/m2, D1 and D2, carboplatin 300 mg/m2 D1 and teniposide 100 mg/m2 D1 to D3. All patients were younger than 70 years, 31 males, five females, ten limited diseases, 26 extended diseases (without brain metastasis) Performance status 0, 1 or 2, mean weight loss 3.7 kg. Thirty six patients were evaluable for response. We have noted three complete response and 28 partial response (objective response rate 86%). The main toxicity of this combination therapy was myelo-suppression (86% of grade 3 and 4). Twenty seven patients have relapsed, the median relapse free survival time is 310 days. The median survival of the 36 patients is 340 days, one patient is alive more than 30 months after the diagnosis. The ifosfamide-carboplatin-teniposide combination is an effective treatment in small cell lung cancer, its toxicity remains tolerable.

[First intention treatment with josamycin in primary acute pneumopathies of infectious origin in adults]. / Traitement de première intention par josamycine au cours des pneumopathies aiguës primitives d'origine infectieuse chez l'adulte.

In a prospective study 128 community acquired pneumoniae were treated with a macrolide (josamycin) by oral route. Patients improved in 94 p. 100 (113). Complications were as following: 2 deaths, 2 sequels, 3 failures. Authors discuss macrolides effectiveness in acute pneumoniae, particularly pneumococcal ones. They conclude macrolides are a good choice in first intention in acute pneumoniae of adults.

[Diffuse bronchomalacia after double lung transplantation. Thoughts apropos of a case]. / Bronchomalacie diffuse après greffe pulmonaire bilatérale. Réflexions à propos d'un cas.

A 40 year old woman suffered from respiratory insufficiency (arterial PaO2 = 47 mmHg) because of a chronic beryllium intoxication. On 6th June 1990, she underwent double lung transplantation with cardio-pulmonary bypass. Each lung was separately implanted via an extra-pericardial approach, and both bronchi were anastomosed at the hilum. On the seventh post operative day, a severe bilateral bronchial ischemia was noticed (black mucosa). Few weeks later, a diffuse bronchomalacia was noticed in the proximal and distal parts of both bronchial trees. To our knowledge, such a bronchial post-ischemic complication has never been reported. The explantation could be several added causes: imperfect preservation of the lung during harvesting, post operative pulmonary oedema, and operative use of an antifibrinolytic agent (aprotinin).

[Diagnosis of broncholithiasis. Role of high resolution tomodensitometry]. / Diagnostic de la broncholithiase. Rôle de la tomodensitométrie haute résolution.

PURPOSE: to evaluate high resolution computed tomography (HRCT) in the diagnosis of broncholithiasis. PATIENTS AND METHODS: 10 patients with broncholithiasis underwent chest X ray, fiberoptic bronchoscopy (FOB), CT and HRCT. RESULTS: in 9 cases, chest X rays were abnormal but the diagnosis of broncholithiasis can't never be affirmed. In 9 cases, FOB was abnormal: broncholith were identified in only 2 cases; the other diagnosis were tumor like stenosis (n = 3), inflammatory stenosis (n = 3), extrinsic compression (n = 1). On conventional CT scan, broncholithiasis was suspected in 8 patients but because of volume averaging the relationship between calcified lymph nodes and bronchial tree was difficult to determine exactly. Only HRCT sections, sometimes tilted in the axis of the middle lobar bronchus, can affirm the endobronchial or peribronchial location of calcified lymph nodes in all patients. CONCLUSION: conventional CT scan can suggest the presence of broncholithiasis but HRCT sections are need to affirm the diagnosis.

[Mediastinal lymph node extension in primary bronchial cancer: correlation of x-ray computed tomography, magnetic resonance imaging and mediastinoscopy. Apropos of 50 cases]. / L'extension ganglionnaire médiastinale dans le cancer primitif des bronches: corrélations entre la tomodensitométrie, l'imagerie par résonance magnétique et la médiastinoscopie. A propos de 50 observations.

Based on a homogeneous series of 50 cases investigated within less than a week by CT scan and NMR imaging with mediastinoscopic correlation, and in 32 of theses cases with correlation with operative findings, a critical study was carried out of modern imaging methods for detection of mediastinal gland invasion from primary bronchial cancer. Axial mediastinoscopy presented absolute specificity and very high sensitivity (93%) markedly superior to those of CT scan and NMR imaging. The two latter examinations were practically of equal efficacy: sensitivity of NMR (80%) was somewhat higher than that of CT scan (70%) whereas specificity of CT scan was 83% as against 70% for NMR. Lack of efficacy of axial mediastinoscopy was in cases with extra-axial lymphatic extension (anterior mediastinal chains) from primary cancer. These results suggest that, in view of current inconveniences of NMR imaging, the best means for local and regional exploration of primary bronchial cancer preoperatively is combined CT scan and mediastinoscopy. The diagnosis of glandular enlargement of anterior mediastinal lymphatic chains should lead to performance of an anterolateral mediastinoscopy.

[Bilateral chylothorax]. / Un chylothorax bilatéral.

We report a case of spontaneous bilateral chylothorax appearing in a woman suffering from kyphoscoliosis. A cure was obtained after one pleural tap and three weeks of rest with a special alimentary diet. We discussed as a possible cause the tearing of the thoracic duct secondary to movements resulting from the hyperextension of the vertebral column.

[Bronchial adenocarcinoma in tuberculosis scars]. / Adénocarcinome bronchique sur cicatrices tuberculeuses.

The relation between bronchial cancer and fibrous scars still remains controversial. We report, with regard to a typical case, the histological arguments for this hypothesis in the knowledge that only a clinical history and above all a radiographic progress will evoke the carcinomatous transformation. We report on the diagnostic peculiarities, the evolution, the therapeutic approach and histogenetics of bronchial cancers developing on a scar. This association and the interest of pursuing these investigations in the presence of evocative clinical or radiographic anomalies enable a better understanding of the natural history of bronchial cancer.

[Tracheo-bronchial granular cell tumors. Apropos of 4 cases]. / Les tumerus trachéo-bronchiques à cellules granuleuses. A propos de quatre observations.

We have seen four cases of granular cell tumor (Abrikossoff's tumour) and it is recalled that these tumours are most often discovered fortuitously by bronchoscopy in the tracheo-bronchial region because they have a non specific clinical presentation. The cytological and histological characteristics enable an accurate diagnosis but there are problems posed as to the histogenesis of these tumours. With a tumour with a slow progression regular surveillance with regular biopsies seems preferable as in certain cases the tumour regresses spontaneously or disappears after ablation with the forceps. A good alternative approach is destruction of the tumours with a laser in certain complicated forms which enables one to avoid surgical excision.

[A specific etiology of radiologic cannon balls: sarcoidosis. Apropos of a case]. / Une étiologie particulière du lâcher de ballons radiologique: la sarcoïdose. A propos d'une observation.

A distinctive form of sarcoidosis is reported. A young woman, without any past medical history, presented with a cannon-ball radiographic appearance and a fever, suggesting an infection or underlying neoplasm. A lung biopsy gave the diagnosis of sarcoidosis after negative fibreoptic bronchoscopy, bronchial lavage and needle biopsy. This macronodular form of sarcoidosis is known but rarely described. There was a favourable clinical and radiological outcome, which occurred spontaneously.

[Diffuse infiltrative lung diseases: histological support of elementary lesions observed on tomodensitometry]. / Pneumopathies infiltratives diffuses: support histologique des lésions élémentaires observées en tomodensitométrie.

High resolution computed tomography (TDM-HR) is now the technique of choice in the diagnosis and management of diffuse infiltrative lung disease (PID). After a brief review of the technique the authors describe the normal appearance; anatomical observations and the in vivo findings have shown that TDM-HR allow for the exploration of details of structure down to the second pulmonary lobule. Thus, through the alterations that are transmitted in the lobular area, and from its contents and its limits, PID has led to the elaboration of a new semeiology. The authors review the basic computed tomographic images and correlate these in each case with the histological evidence. The spatial distribution and the time sequence of the elementary images are the two other terms in the diagnostic equation of PID. The spatial distribution of several elementary images presents in TDM-HR a superior aetiological pointer to that which is furnished by thoracic radiographs; and the time sequence may furnish a useful indication as to the progress of the treated disease. Sarcoidosis, histiocytosis X, idiopathic interstitial fibrosis and lymphangitis carcinomatosis would serve as examples. Nevertheless, the authors point out that it would be dangerous during the period of evaluation to prematurely extend to all cases of PID conclusions which are only possible to make at present in a restricted number of disorders.

[Comparative study of magnetic resonance imaging and tomodensitometry in the diagnosis of locoregional extension in 61 patients with bronchial cancers]. / Etude comparative de l'imagerie par résonance magnétique et de la tomodensitométrie dans le diagnostic d'extension locorégionale de 61 patients porteurs de cancers bronchiques.

In order to assess the value of nuclear magnetic imagery NMR in the diagnosis of the extent of bronchial cancers, 61 patients with operable bronchial carcinoma had both a CT scan and an NMR scan pre-operatively. Fifty one mediastinoscopies were performed. Twelve times there were mediastinal glandular enlargement. Ten times the thoracotomy was performed straight away. After pathological studies of the biopsy, 24 patients were N2, 25 N1, 12 N0; the sensibility of NMR to foresee lymph node invasions was 83% (specificity 70%), for CT scanning 75% (specificity 81%). Thirteen patients presented with a direct mediastinal or parietal invasion. The sensibility of detecting these invasions was only 38% for NMR (specificity 94.5%) and for CT scanning 54% (specificity 94.5%). There is little difference in the results and no statistical difference. This leads us to conclude that at present, NMR does not give more information than TDM in the diagnosis of operability in bronchial cancers.

[Value of computed tomography in the diagnosis of the intrathoracic extension of bronchial cancer]. / Intérêt de la tomodensitométrie (TDM) pour le diagnostic d'extension intrathoracique du cancer bronchique.

In 76 patients the diagnosis of the mediastinal extension of a bronchial cancer, assessed by computed tomography (CT), was compared to histological specimens obtained by mediastinoscopy and surgery (58/76). The extension to mediastinal nodes was present in 26 subjects (34.2%) and yet was not recognised 15 times on CT. There were 15 false negatives (FN) and 3 false positives (FP). Sensitivity 43%, specificity 94%, predictive value for positives (VPP) 70%, predictive value for negatives (VPN) 75%. Extension was present in 18 patients. These were recognised 14 times by CT. There were no false positives. (Sensitivity 70%, specificity 100%, VPP 100%, VPN 94%). We conclude That CT is useful for diagnosing direct mediastinal extension and allows the juxta-hilar extension of the cancer to be assessed. CT has no place in the diagnosis of mediastinal gland involvement. Mediastinoscopy (5.2% FN; no FP) is better than TDM for the diagnosis of extension to the mediastinal nodes both for peripheral and central cancers.

[Primary pulmonary malignant fibrohistiocytoma. Apropos of a case]. / Fibrohistiocytome malin pulmonaire primitif. A propos d'un cas.

A case of primary malignant fibrous histiocytoma of the lung is reported. The clinical course was divided into 2 periods: slow tumoral growth followed by rapid aggravation. The pathological aspects of the first localization and of the relapse are analyzed and discussed. Data from the literature are reviewed, with special attention to diagnostic and prognostic problems.

[Primary alveolar hypoventilation. Clinical aspects and diagnostic problems. Apropos of a case]. / Hypoventilation alvéolaire primitive. Aspects cliniques et problèmes diagnostiques. A propos d'une observation.

Primary alveolar hypoventilation is a rare syndrome of unknown origin, characterized by a dysfunction of the automatic respiratory pattern in spite of normal lungs and in the absence of mechanical ventilatory defects. A reduction of the ventilatory response to CO2 is regularly found, and cardiac failure is common. The differential diagnosis mainly concerns the sleep apnoea syndrome. The usual treatments have little effectiveness.

[Rheumatic pelvispondylitis and non-tuberculous sclerotic lesions of the pulmonary apex]. / Pelvispondylite rhumatismale et lésions scléreuses non tuberculeuses des sommets.

Two new cases of rheumatic pelvispondylitis associated with bilateral fibrosis of the pulmonary apex are reported and published data are reviewed. The clinical, radiological, evolutive and diagnostic features of this probable pulmonary manifestation of rheumatic spondylitis are described, and the pathogenesis is discussed.
