[Prognostic factors in idiopathic pulmonary fibrosis in a tunisian cohort]. / Facteurs pronostiques au cours de la fibrose pulmonaire idiopathique : étude d'une cohorte tunisienne.

We present data on prognostic factors in a Tunisian cohort of people with Idiopathic pulmonary fibrosis. INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) has a poor prognosis, with a median survival in patients with the condition of only 3 to 5 years. Previous studies have identified a number of prognostic factors in this chronic pulmonary disease. METHODS: We conducted a retrospective study, including patients with idiopathic pulmonary fibrosis (IPF) who were diagnosed at the Pneumology Department of the University Hospital Fattouma-Bourguiba, Monastir, between 1991 and 2014. The aim of this study was to compare clinical, radiological, pulmonary functional predictors of survival in IPF in a Tunisian cohort with those of previous studies. RESULTS: This study included 126 patients. Their mean age was 66 years, with a male predominance (68.3%). Respiratory function tests revealed a restrictive ventilatory deficit in 72.6% of cases. The median survival of our study population was 22.5 months [6.7-49.5]. In univariate analysis, factors associated with a poor prognosis were: lower baseline values of TLC, FCV and DLco, level of dyspnea assessed by mMRC scale, hypoxemia at diagnosis, the degree of desaturation during exercise, a higher annual decline of FVC and DLco, acute respiratory distress and also the GAP score. In multivariate analysis, independent prognostic factors were: baseline DLco, level of dyspnea, desaturation at exertion and the annual decline of the DLco. CONCLUSION: Lower baseline DLco, the level of dyspnea, desaturation on exercise, and annual decline in DLco are all associated with a poor prognosis in IPF.

[Fight against tuberculosis in the world]. / La lutte antituberculeuse dans le monde.

Tuberculosis (TB) in a major health problem in the world. WHO and its partners especially, the stop TB partnership launched numerous strategies against TB especially in the 1990. Strategy DOTS (directly observed therapy short course) was launched in 1995. One main key was the direct supervision of drug intake by patients. Progress was achieved but it was insufficient. A new strategy called "Stop TB Strategy 2006-2015" was launched in 2006 in the context of Millennium Development Goals (MDG) elaborated by United Nations. The common goals were to halt and start to reverse the incidence of TB, reduce the prevalence and death rate by 50% compared to their level in 1990 by 2015 to eliminate TB as a public health problem by 2050. The end of 2010 marks the mid-point of the Global Plan and is an obvious time to update it and take into account actual progress with a focus on the 2015 to reach goals. So an updated Global Plan to stop TB 2011-2015, was launched. Expected progress and targets were defined for 2015, in diagnosis and treatment, in co-infection TB/HIV, in drug-resistant TB and achievements expected in new tests for diagnosis, new medications, new vaccines and new regimens with shorter duration of treatment. WHO and partners have started discussions to define the new post 2015 strategy to TB control and elimination. Risk factors (diabetes, malnutrition, tobacco smoke…) and socioeconomic factors, which are associated with TB, should be included in the new strategy to eliminate TB in 2050.

[Epidural emphysema complicating bronchial asthma]. / Emphysème épidural compliquant un asthme bronchique.

Epidural emphysema is an exceptional complication of bronchial asthma, revealed by an incidental finding in chest tomography. We report a case of a 21-year-old man admitted with asthma attack complicated by subcutaneous and mediastinal emphysema. Chest tomography confirmed the mediastinal emphysema and also revealed the epidural emphysema within the vertebral canal. Neurological examination was negative. The patient showed complete recovery 10days after the onset of symptoms. The epidural emphysema is a rare complication during asthma attacks. The benignity of this complication should not require a systematic chest tomography.

[Spontaneous pneumothorax associated with ankylosing spondylitis]. / Pneumothorax spontané au cours de la spondylarthrite ankylosante.

Ankylosing spondylitis (AS) is a chronic inflammatory disease that affects the axial skeleton and more frequently the sacro-iliac joints. Pleuropulmonary involvement is an uncommon event. Apical fibrosis, interstitial infiltrates, and pleural thickening are thought to be the main patterns. Rare cases of spontaneous pneumothorax were reported in the literature. A 62-year-old man, who had a diagnosis of AS since May 1994, was admitted for exertional dyspnea. The diagnosis of apical fibrosis related to AS was essentially based on radiological arguments. The patient was again hospitalized in 2011 for thoracic pain. Computed tomography of the chest revealed a right partial pneumothorax. The evolution was marked by the total regression of the pneumothorax under oxygen and strict rest.

[Choroid metastases revealing pulmonary adenocarcioma resolved with chemotherapy]. / Métastases choroïdiennes révélatrices d'un adénocarcinome bronchique et involuant sous chimiothérapie.

Lung cancer is the leading cause of choroidal metastasis in men, but choroidal metastasis is rarely inaugural. With the advent of new generations of chemotherapy molecules non-small-cell lung cancer (NSCLC) has become more chemosensitive. Choroidal metastasis may respond to chemotherapy. We report a case of a 52-year-old men who developed choroidal metastasis revealing pulmonary adenocarcinoma confirmed by the bronchial biopsy. Systemic chemotherapy using gemcitabine-cisplatin led to total involution of the choroidal metastasis with improvement of the visual acuity in one eye and stabilization in the other. Systematic search for lung cancer is required in patients presenting choroidal metastasis. If compatible with the patient's general status, histologically-adapted chemotherapy must be instituted. This approach can avoid the use of radiotherapy and therefore deterioration of visual acuity after radiation.
