Ductus diverticulum is either a remnant of the ductus arteriosus or the right dorsal aortic root. The most common diagnosis is the differentiation of an aortic isthmus pseudoaneurysm from a type III ductal diverticulum. Both aortic entities occur at roughly the same anatomical location often leading to diagnostic confusion. Aortic dissection should be considered if it is Takayasu's disease. We are reporting the case of a 31-year-old woman with chest pain and muscle weakness, functional impotence of the left upper limb with intermittent palpitations. Thoraco-abdominal CT angiography was in favor of inflammatory arteritis of the thoraco-abdominal aorta, common carotids and the left subclavian artery. Sub-occlusive stenosis of the left axillary artery was noted, in favor of Takayasu disease. There was an aspect of aortic ductus diverticulum type III, 24mm from the emergence of the subclavian artery simulating aortic dissection or ulceration of the aortic isthmus. An electrocardiogram revealed Wolff Parkinson White syndrome with left lateral Kent. There was good clinical outcome after immunosuppressive drugs and antiarrhythmic therapy.

Background Lung cancer is a major cause of death worldwide. However, few data on incidence, histologic types and mortality rates of lung cancer were available for Algeria. Methods LuCaReAl is an ongoing descriptive, non-interventional, national, multicenter, prospective and longitudinal study conducted in Algeria, among oncologists and pulmonologists in public community and university hospitals. Median and interquartile ranges are displayed. Results Between July 2016 and July 2017, 897 patients were included. Overall incidence of lung cancer was 3.4 [3.2;3.6] cases per 100,000 inhabitants; overall incidence by sex was 5.8 [5.4;6.2] for males and 1.0 [0.8;1.1] for females. Adenocarcinoma was the most common histologic type of cancer. Most tumors were diagnosed at Stage IV. Conclusion The first results from the LuCaReAl study in Algeria showed that most patients are diagnosed with lung cancer at an advanced stage. The ongoing follow-up will next provide data on the survival and mortality rates.

Several studies suggest that frequent exacerbations (≥2 exacerbations / year) are associated with severity of COPD and poor quality of life in subjects with COPD. Our objective was to identify features associated with frequent exacerbations of COPD. Methods: A cross-sectional analysis of data obtained from Algerian patients prospectively recruited in a specialized consultation. The cohort included 142 subjects with COPD (67 ± 10 years, FEV1, 53 ± 19 % of the predicted value). Subjects with frequent exacerbations defined by 2 or more exacerbations in the last year (n= 52) and subjects with less than 2 exacerbations last year (n= 90), were compared. Results: No difference was observed between groups for age, smoking status, anxiety, depression score (anxiety depression scale questionnaire), MCS score (MOS SF-36), and comorbidities. The subjects with frequent exacerbations were more symptomatic (mMRC score 1.82±0.78 vs 1.48± 0.67) p.0.008, their airflow limitation was more severe (43.71±19.1 vs 59.77±16.44 % of the predicted value) p ˂0.001, distance traveled at the 6-minute walk test, PCS score (MOS SF-36), and BMI were significantly lower than others,(332.69±116 m vs 375.52±109 m) p0.03,(36.92±9.34 vs 42.69± 8.75) p0.001, (22.49±3.81vs 24.49±5.21) p0.01 respectively. Chronic cough and sputum production was more common in subjects with frequent exacerbations, 48% vs 26% p0.01. Chronic cough, sputum production and severity of airflow limitation were the only variables associated with frequent exacerbations p.0.007 and p0.001 respectively (logistic regression). frequent exacerbation is associated with severity of airflow limitation and chronic cough, sputum production.

Anemia is a common consequence of cancerous disease. In lung cancer its prevalence is 37.6%, and its incidence after chemotherapy treatment is 80%. It is a prognostic factor for survival and may affect the efficacy and safety of chemotherapy and radiation therapy. Objective: To estimate the prevalence and incidence of anemia in patients with lung cancer. Methods: retrospective study including all patients treated for lung cancer who had at least one anemic episode during 3 years. Results: The analysis included 264 lung cancer patients with hemoglobin less than 80% of normal, anemia was found in 33.7% of patients before any treatment, and in 66.3% of those treated with chemotherapy. The median age was 62 years ( Conclusion: Both the prevalence and incidence of anemia in lung cancer should be taken into consideration because of the strong correlation between anemia and quality of life and the prognosis of patients with.

Introduction: Among the extra pulmonary tuberculosis, the tuberculous pleurisy takes the second place after peripheral tuberculous lymphadenitis in our country. The diagnosis is usually difficult, due to the low sensitivity of conventional methods. The new immunological tests have been used to improve the diagnostic sensitivity of tuberculous pleurisy and overcome the inadequacies of conventional methods. Interferon gamma (IFN-γ) is one of these tests. Objective: Assess the performance and clinical interest of QuantiFERON-TB Gold In-Tube (QFT-GIT) in the tuberculous pleurisy diagnosis. Methods: The QuantiFERON TB-Gold In Tube (QFT-GIT) test was analysed in blood and pleural fluid from 158 immunocompetent patients (84 patients for the tuberculous group and 74 patients for the non-tuberculous group) Results: The QFT-GIT in pleural fluid was positive in 82 (97.6.5%) patients and indeterminate in 2 (2, 4%) patients in the tuberculous pleurisy group which was also confirmed by the conventional methods. There was not a single patient with a negative test result in this group. In blood, the QFT-GIT was positive in 68(81%), negative in 11 (13%) and indeterminate in 5 (6%). The sensitivity, specificity, positive predictive value and negative predictive value of QFT-GIT in pleural fluid for tuberculous pleurisy were 95.1%, 67, 7%, 66, 1% and 95, 5%; and of QFT-GIT in blood the results were 86, 1%, 84, 5%, 86, 1% and 84, 5% respectively. In conclusion: QFT-GIT in the blood and in the pleura appears to be a useful test in our study for the diagnosis of tuberculous pleurisy despite the fact that its specificity is low in the pleura.

In Algeria, the emergency hospital is the main pillar of primary care medicine. Study objective Description medical characteristics, and management of patients consulting for respiratory emergencies. Prospective: study of persons presenting to the emergency department of Bab El Oued hospital, as part of an unscheduled consultations for respiratory symptoms during the period of the investigation. The collection is made from November 1, 2014 to January 20, 2015. Data collection was done by doctors in their care at the emergency center using a questionnaire. Results: During the survey period, 123 patients were collected. The largest recourse levels concerned the over 70 years (40 cases). 47% of patients had consulted the emergency department for the current episode at 2.8 times on average, and 21 patients were in exploration with an average time between the last consultation and reliance on emergency 10 days. In 30% of cases, the situation that led to consult dated from the same day but in 70% of cases, she dated back or several days. Half of the patients had at least one associated comorbidity. The reasons for consultation were: dyspnea, cough and fever. In 43 % of cases, it was a simple consultation with no associated therapeutic procedure and the most prescribed treatment to patient discharge were antibiotics. Diagnoses made at the end of treatment were dominated by acute respiratory infections followed by COPD exacerbations. The majority of patients returning home after their passage to emergencies, but 21 were hospitalized. The average length of stay in the emergency center was 2.3 days. Conclusion: The majority of emergencies received during the investigation period was not considered real emergencies.

Introduction: nitric oxide (NO), produced by the inducible nitric oxide synthase (iNOS), is important in host defence against Mycobacterium tuberculosis in animal models. But the presence of high output NO production in human tuberculosis has been controversial. Objective: To investigate nitric oxide expression (NO) in pleural tuberculosis Methods: The serum and pleural fluid NO in the patients with exsudative pleural effusion were analyzed. Results: Of total 151 patients, there were 77 males and average age of patients was 47, 28 ± 19, 5 years. The final diagnosis was tuberculous pleurisy in 84 cases and malignant pleural effusion in 67. The pleural fluid NO level was 68, 46 ± 57, 88 μmol in the tuberculous pleurisy patients and 62, 39 ± 51, 45 μmol in the malignant pleural effusion patients (p Conclusion: NO is not a suitable marker for tuberculous pleuritis because, because it is produced in other pathologies such as neoplasic and inflammatory diseases.

The aim of our study was to determine the frequency and reasons for emergency room visits of patients with lung cancer and the procedures and results of their treatment. Patients and methods: Retrospective study on all patients with lung cancer monitoring within the hospital of Bab El Oued pulmonology department from January 2008 to November 2014 and has submitted an acute symptoms requiring emergency consultation. Results: Among the 858 patients with lung cancer followed in the pulmonology department during this period, 718 had emergency consultation, primarily for poor general condition 37.7%, respiratory complaints 40.6%, pain 19%, convulsion 12% or severe infectious syndrome 2%. The reason for consultation was mainly due to toxicity of treatment in 35% of cases and tumor progression in 29.8% of cases. The main diagnoses were superior vena cava syndrome 5.4%, brain metastases 15.6%, spinal cord compression 5.9%, pleural and pericardial effusions 10.2%, infection severe 2%, respiratory distress 2.8%, thromboembolic disease 13.3%, grade 3/4 anemia 23.6%, grade 3-4 neutropenia 8%, thrombocytopenia grade 3-4 4%, hyponatremia 3.1% and hypocalcemia 0.8%. The main treatments given included a decompressive radiation therapy in 21.7% of patients, anticoagulants in 13.3% of cases, a blood transfusion in 23.6% of cases and corticosteroids 23.8%, antibiotics 13, 3%. In the short term, mortality was 3.4%. Conclusion: Lung cancer patients frequently consult the emergency department for complications related to cancer or its treatment this underlines the importance of early use of supportive care alongside the oncological treatment.
