Can Coronavirus Disease 2019 Induce Sarcoidosis: A Case Report.

Since the emergence of coronavirus disease 2019, a large spectrum of clinical manifestations following this acute viral infection has been reported especially autoimmune manifestations and inflammatory disorders. However, a causal link has not yet been established. Herein, we reported a case of pulmonary mediastinal sarcoidosis following coronavirus disease 2019 infection.

Tracheal Lobular Capillary Hemangioma: A Rare Localization.

Background: Lobular capillary hemangioma is a benign vascular tumor commonly found within the skin and upper respiratory mucosa and has rarely been reported within the trachea. The first case was reported by Irani et al. in 2003 and since then, less than 20 cases have been described.

Idiopathic double tracheal stenosis mimicking asthma: a case report.

Idiopathic tracheal stenosis (Idio-SS) is an extremely rare disease. Its diagnosis is of exclusion and could be misdiagnosed as asthma. Herein, we report the case of a 39-year-old woman who had been treated for asthma for several months.

Brain metastases of non-small cell lung cancer: prognostic factors and management.

Background: The prognosis of patients with non-small cell lung cancer (NSCLC) with brain metastasis (BM) is dark. The aim of our study was to analyze the prognostic factors after the onset of BM and to evaluate the current management of BM.

Methods: We conducted a retrospective study that included 100 patients diagnosed with primary NSCLC with BM.

Chronic arthritis revealing sarcoidosis in a patient exposed to silica.

Sarcoidosis is a systematic, granulomatous disease of unknown cause which can affect any organ in the body. Pulmonary involvement is the most common. Musculoskeletal manifestations of sarcoidosis are less common affecting 10-25% of patients and chronic arthritis occurs rarely.

Impact of malnutrition in advanced non-small cell lung cancer.

Background: Malnutrition is so commonly associated with cancer disease. Our work aims to highlight the impact of malnutrition on the survival and toxicity of chemotherapy in patients with advanced stages of non-small cell lung cancer (NSCLC).

Methods: A retrospective study including 60 patients followed for NSCLC stage IIIB and IV, between January 2007 and December 2013.

Unicentric Castleman's disease: an uncommon cause of chronic cough.

Castleman disease (CD) or angiofollicular lymph node hyperplasia is a rare lymphoproliferative disorder characterized by lymph node hyperplasia of uncertain etiology. CD is divided clinically into unicentric (localized to one region of the body) considered as a benign disease and multicentric with less favourable prognosis. We describe a case of intrathoracic unicentric CD revealed by a chronic non-productive cough in a 50-year-old non-smoker female.

Combined C-reactive protein and Neutrophil to Lymphocyte ratio use predict survival innon-small-cell lung cancer.

Background: Inflammation markers have been shown to predict prognosis during cancer including non-small cell lung cancer (NSCLC). In particular, C-reactive protein (CRP) and Neutrophil to Lymphocyte Ratio (NLR) have been investigated. The aim of our work is to study the combination of these two markers in optimizing prognostication in advanced NSCLC.

Particularities of community- acquired pneumonia in the elderly.

Background: Acute community-acquiredpneumonia in olderadults has averysevereprognosiswith a mortality rate whichcanreach 10%. Knowing the clinical, etiological, therapeutic and progressive features of thisdiseasecan help to establish management rulesthatcanimprove the prognosis. The aim of ourstudywas to compare the community-acquiredpneumonia profile in olderadults and youngerthem.

Advanced Lung Cancer Inflammation index: a prognostic score in patients with metastatic non-small cell lung cancer.

Introduction: Recent studies have identified that inflammation had a significant association with cancer development and progression.

Aim: To explore the relationship between ALI score and prognosis of metastatic non-small cell lung cancer (NSCLC).

Methods: we conducted a retrospective study of 41 patients with metastatic NSCLC diagnosed between January2010 and January2012.

Prognostic factors for second-line chemotherapy of metastatic non-small-cell lung cancer.

Background: Few studies have been conduct¬ed to determine prognostic factors of second-line chemotherapy. The aim of this study was to determine the prognostic factors for survival in patients receiving second-line treatment for advanced NSCLC.

Methods: We retrospectively reviewed the records of 71 patients with metastatic NSCLC who received second-line chemotherapy from January 2006 to January 2013.

Primary sarcomatoid lung cancer: clinical and evolutive features: about five cases.

Background: Primary sarcomatoid carcinoma of the lung are rare non small cell lung cancers (NSCLC) recently individualized by the World Health Organization. Their clinical, radiological and evolutive features are not well known but they seem to have bad prognosis with rapid progression and early metastases. Although they are felt to be chemo-refractory they must be treated as the other subtypes of NSCLC.

Pulmonary embolism and tuberculosis.

Tuberculosis has a high prevalence in Tunisia, but pulmonary embolism is rarely reported in Mycobacterium tuberculosis infection. We describe 3 cases of pulmonary embolism associated with severe pulmonary tuberculosis. Pulmonary embolism occurred within 2 to 13 days of pulmonary tuberculosis diagnosis.
