Resume Les etiologies des syndromes cavitaires pulmonaires sont multiples, notamment neoplasiques, infectieuses ou inflammatoires. Une etiologie particuliere est celle d’infarctus pulmonaires multiples secondaires a des embolies pulmonaires. Ce diagnostic peut etre suspecte devant la localisation sous-pleurale des lesions et l’association avec un thrombus arteriel pulmonaire. Nous rapportons le cas d’une patiente atteinte d’une hypertension pulmonaire post-embolique (HTP PE) chronique associee a une thrombophilie familiale revelee par des infarctus pulmonaires excaves. L’HTP PE chronique est parfois diagnostiquee lors d’une recidive embolique sur des lesions anciennes passees inapercues. Parmi les conditions medicales associees au developpement d’une HTP PE, figurent certaines thrombophilies telles que l’elevation isolee du facteur VIII.

Mycobacterium chelonae (M. chelonae) is rarely responsible for respiratory infection. This report concerns the case of an 81-year-old man with previously asymptomatic bronchiectasis, colonised by M. chelonae for 3 years. He was hospitalised for acute dyspnoea and fever due to a right hydro-pneumothorax with cavitated alveolar opacities of the right lung. Pleural fluid and bronchial aspiration were positive for M. chelonae and no other microorganisms were detected. The effusion was drained and the patient treated with clarythromycin and amikacin. The radiological abnormalities improved but the patient's general condition remained poor. Treatment was continued for 11 months. Because of the absence of any other bacteria, clinical deterioration following broad-spectrum antibiotics and stabilisation of the lesions after anti-mycobacterial treatment, our diagnosis was severe M. chelonae pleuro-pneumonia in an immunocompetent patient.

L’omalizumab (OMZ) a une AMM depuis 2005 dans l’asthme severe allergique avec un allergene perannuel retrouve. Ce travail a pour objectif d’evaluer l’adequation de la prescription de l’OMZ et son efficacite en utilisation courante dans un centre de pneumologie. Patient et methodes Etude retrospective monocentrique. Tous les pts (n = 55) ayant recu de l’OMZ entre 2003 et 2014 ont ete inclus. Les criteres de severite, l’adequation de la prescription par rapport aux recommandations de l’AMM et l’efficacite du traitement ont ete analyses. Resultats Tous les pts avaient un asthme severe (VEMS moyen 61 %, ACT moyen 11,6, Nombre moyen d’EA : 5,44/an). Cinquante-quatre pour cent des patients recevaient une corticotherapie orale, tous avaient des doses elevees de CSI (> 1000 mcg/j). Quatre-vingt-cinq pour cent avaient un allergene perannuel. 10 pts avaient des taux d’IgE ou un poids hors des tables d’AMM : IgE 1500 : n = 3, IgE > 30 et Conclusion La prescription d’OMZ n’etait pas conforme aux recommandations dans 15 % des cas du fait de l’absence d’allergene perannuel identifie et dans 18 % des cas car ils etaient hors des tables de dosage recommande. L’efficacite de 66 % est proche de la litterature, mais 18 % ont presente un EI imposant l’arret du traitement.

In the past few years some new inhaled drugs and inhalation devices have been proposed for the treatment of cystic fibrosis. Breath-controlled nebulizers allow increased pulmonary deposition, with a lower variability and a shorter delivery time. The new dry powder formulations of tobramycin, colistine and mannitol require a change in the inhalation technique which must be slow and deep. In the field of the inhaled mucolytic drugs, hypertonic saline and mannitol have an indication in some patients. With regard to antibiotics, dry-powder tobramycin and colistine can be substituted for the same drug delivered by nebulization. Nebulized aztreonam needs more studies to determine its place. These new treatments represent a definite advance for cystic fibrosis patients and need to be known by all practitioners. Their position in our therapeutic arsenal remains to be accurately defined.

Several etiologies are involved in the pathogenesis of cavitating pulmonary disease including neoplastic, infectious or inflammatory processes. Another is pulmonary infarction associated with venous thromboembolism. The lung cavities tend to be located peripherally and are the result of pulmonary embolism. We report the case of a woman with chronic thromboembolic pulmonary hypertension (CTEPH), associated with familial thrombophilia, revealed by cavitating pulmonary infarcts. CTEPH is sometimes diagnosed during an episode of recurrent pulmonary embolism following previously unnoticed lesions. Thrombophilias such as isolated elevated factor VIII are risk factors for CTEPH.

We report two cases of malignant lymphoma of B phenotype occurring after therapeutic pneumothorax for tuberculosis. In both cases, outcome was fatal without time for specific treatment. Mainly reported in Japan, this pathology seems to be less frequent in western countries. As for B phenotype lymphoma associated with immunodeficiency, association with Epstein Barr virus is reported. Definite diagnosis is difficult and requires surgical biopsy. Prognosis remains poor with a survival ranging from 3 to 6 month.
