INTRODUCTION: Hydroxyurea is an antimetabolite drug used in the treatment of myeloproliferative disorders. Common adverse effects include haematological, gastrointestinal cutaneous manifestations, and fever. Hydroxyurea-induced pneumonitis is unusual. CASE REPORT: A female patient was treated with hydroxyurea for polycythemia vera. She was admitted 20 days after commencing treatment with a high fever, productive cough, clear sputum and nausea. A chest CT-scan showed diffuse ground-glass opacities. Microbiological investigations were negative. The symptoms disappeared a few days after discontinuation of the drug and rechallenge led to a relapse of symptoms. CONCLUSION: Our case and 15 earlier cases of hydroxyurea-induced pneumonitis are reviewed. Two patterns of this disease may exist: an acute febrile form occurring within 1 month of introduction of hydroxyurea and a subacute form without fever. Even if uncommon, one should be aware of this complication of hydroxyurea.

Résumé : International audience
STUDY OBJECTIVE: There is no consensus about the management of large spontaneous pneumothoraces. Guidelines recommend either needle aspiration or chest tube drainage and most patients are hospitalized. We assess the efficiency of ambulatory management of large spontaneous pneumothoraces with pigtail catheters. METHODS: From February 2007 to January 2011, all primary and secondary large spontaneous pneumothoraces from Lorient's hospital (France) were managed with pigtail catheters with a 1-way valve. The patients were discharged immediately and then evaluated every 2 days according to a specific algorithm. RESULTS: Of the 132 consecutive patients (110 primary, 22 secondary), 103 were exclusively managed as outpatients, with full resolution of the pneumothorax by day 2 or 4, which represents an ambulatory success rate of 78%. Mean time (SD) of drainage was 3.4 days (1.8). Seven patients were initially hospitalized but quickly discharged and had full resolution by day 2 or 4, leading to a total success rate of 83%. The use of analgesics was low. The 1-year recurrence rate was 26%. If successful, this outpatient management is potentially cost saving, with a mean cost of 926, assuming up to 2 outpatient visits and 1 chest radiograph, compared with 4,276 if a chest tube was placed and the patient was admitted to the hospital for 4 days. CONCLUSION: Ambulatory management with pigtail catheters with 1-way valves could be a reasonable first-line of treatment for large spontaneous pneumothoraces. Compared with that of other studies, our protocol does not require hospitalization and is cost saving.

Introduction Le cancer du pancréas est une néoplasie souvent diagnostiquée au stade métastatique et au pronostic sombre. Les lésions secondaires pulmonaires, pléiomorphes, sont souvent présentes au diagnostic et peuvent faire découvrir une maladie par ailleurs asymptomatique. Observations Nous rapportons une série rétrospective de trois patientes, âgées de 32 à 74 ans, qui présentaient des images de pneumopathie interstitielle diffuse (PID) ayant conduit au diagnostic de métastases pulmonaires de cancer du pancréas. Pour la première patiente, une sarcoïdose avait été évoquée devant son jeune âge et la négativité des prélèvements écho-endoscopiques digestifs répétés. La deuxième présentait de multiples nodules pulmonaires excavés et un tableau de compression médullaire a conduit à l’obtention rapide du diagnostic anatomopathologique sur les lésions osseuses. Pour la troisième, le terrain de polyarthrite rhumatoïde et l’absence de symptomatologie abdominale faisait rechercher une atteinte en rapport avec son rhumatisme inflammatoire. L’anatomopathologie, sur biopsies pulmonaires pour deux patientes a permis de redresser le diagnostic. Conclusion Devant une PID atypique le recours à des prélèvements invasifs doit être rapide afin de ne pas retarder un diagnostic de cancer, notamment pancréatique
