RESUMO
BACKGROUND: The association between arterial stiffness (AS) and stable coronary artery disease (CAD) has been previously demonstrated. Whether increased arterial stiffness is associated with severe CAD in patients with acute coronary syndrome (ACS) is less explored. AIM: We aim to investigate the relationship between AS parameters and the extent and severity of CAD in patients with ACS. METHODS: The study population consisted of 275 patients with ACS. We measured various AS parameters including pulse wave velocity (PWV), augmentation index (AIx), and central pulse pressure (cPP). CAD extent and severity was evaluated by the number of vessels with greater than 70% stenosis. RESULTS: The study population was predominantly men (77, 5%) with an average age of 56, 4±10, 6 years. One hundred and fifteen patients were diabetic and 97 were hypertensive. One hundred fifty patients were admitted for ST elevation myocardial infarction (54, 5%) and 37, 5% for non ST elevation myocardial infarction. Thirty six percent of patients had single vessel disease and 47, 6% of the study population had multivessel disease. At the multivariate analysis, a positive correlation was observed between the number of coronary vessels disease and PWV. PWV (OR=1,272; IC95% [1,090; 1,483]; p=0,002) and cPP (OR=1,071; IC95% [1,024; 1,121]; p=0,003) were also independent predictors of multivessel disease. CONCLUSION: In patient with ACS, PWV is correlated with the extent of coronary artery disease, as measured by the number of vessels disease. PWV and cPP were also independent predictors of multivessel disease.

INTRODUCTION: The pseudotumorous form of tuberculosis is a rare entity. Whatever its location, it can simulate neoplasia by its radiological and/or endoscopic appearances. We highlight the diagnostic difficulties associated with this type of presentation. METHODS: We performed a retrospective study of inpatient records from 2003 to 2016 in the pneumology department of La Rabta Hospital to identify cases of thoracic tuberculous pseudo-tumor. RESULTS: Seventeen patients were identified. The median age was 41 years and their symptomatology was dominated by cough and general debility. All had abnormal radiology with 10 cases of suspect lesions. Fibre-optic bronchoscopy revealed endobronchial abnormalities in 11 cases. The median overall diagnostic delay was 97 days. The diagnosis was confirmed bacteriologically in five cases, histologically in 14 cases and based on clinical presumption in one case. The progression was favourable: 13 patients have been declared cured and four patients are still undergoing treatment. CONCLUSION: Making a positive diagnosis of thoracic tuberculous pseudotumour can be difficult, as bacteriological samples are often negative. This can lead to a significant delay in diagnosis and treatment.

INTRODUCTION: The benefits of long-term non-invasive ventilation (NIV) in the management of chronic obstructive pulmonary disease (COPD) patients remain controversial. AIM: To analyze the characteristics of COPD patients under home NIV and to evaluate its impact among this population. METHODS: We carried out a retrospective study between January 2002 and April 2016 of COPD patients under long-term NIV at "la Rabta" and the Military Hospital. RESULTS: There were 27 patients with an average age of 64 and a sex ratio (M/F) of 0.92. Active smoking was reported in 96.3%. A persistent hypercapnia following an acute exacerbation of COPD with failure to wean the NIV was the main indication of long-term NIV. We noted a reduction in hospital admissions in the first year of 60% and in intensive care of 83.3% (P<10-3). There was no non-significant decrease of PaCO2 (4.5mmHg). There was no modification in FEV 1 and in FVC (P>0.05). The survival rate was 96.3% at 1 year, 83.3% at 2 years and a median survival of 24 months. CONCLUSIONS: Our study suggests that home NIV contributes to the stabilization of some COPD patients by reducing the hospitalizations rates for exacerbation. More prospective studies are needed to better assess the impact of NIV on survival and quality of life and to better define the COPD patients who require NIV.

INTRODUCTION: Asthma takes up a great importance in occupational diseases but remains underestimated as it is insufficiently diagnosed. OBJECTIVE: We aimed to access the clinical and professional profile of the Tunisian asthmatic worker. MATERIALS AND METHODS: It was a retrospective descriptive study in a professional pathology unit in a university hospital. All patients referred by their doctor for symptoms suggestive of occupational asthma, during a period from 2000 to 2008, were included. RESULTS: Forty-eight patients were selected from 172. The mean age was 40 years, with a male predominance (56 %). In 2/3 of the cases, it was the textile workers, food and chemical industry. The etiological agents incriminated were textile dust in 18.8 % of cases followed by isocyanates and flour. Typical episodes of wheezing dyspnea were present in 52 % and atopy in 54.2 % of workers. In 2 % of cases, symptoms disappeared and worsened in 18.8 %. CONCLUSIONS: The prognosis of OA depends on early end accurate diagnosis. The physician's role is to initiate the appropriate diagnostic approach, which must comply with the Tunisian conditions.

The apnoea-hypopnoea index (AHI) is the primary measurement used to characterize the obstructive sleep apnoea-hypopnoea syndrome (OSAHS). Despite its popularity, there are limiting factors to its application such as night-to-night variability. AIM: To evaluate the variability of AHI in the OSAHS. PATIENTS AND METHODS: A prospective study was designed in our university hospital's sleep unit. Adults with clinical suspicion of OSAHS underwent 2 consecutive nights of polysomnographic recording. The population was divided in two groups according to an AHI>or<10. Patients with psychiatric disorders or professions that might result in sleep deprivation or an altered sleep/wake cycle were excluded. RESULTS: Twenty patients were enrolled. The mean age was 50.6±9.3 years. OSAHS was mild in 4 cases, moderate in 6 cases and severe in 8 cases. AHI was less than 5 in two cases. AHI values were not significantly altered throughout both recording nights (33.2 vs. 31.8 events/h). A significant positive correlation was found between AHI measured on the first and the second night. However, a significant individual variability was noted. Comparison between both patient's groups showed a correlation between AHI and the body mass index. CONCLUSION: This study demonstrates that the AHI in OSAHS patients is well correlated between two consecutive nights. However, a significant individual variability should be taken into consideration, especially when AHI is used in the classification of OSAHS or as a criterion of therapeutic success.

Tuberculosis is a major public health problem worldwide. Indeed, a third of the world population is infected with Mycobacterium tuberculosis and more than 8 million new cases of tuberculosis each year. Pulmonary tuberculosis is the most common location. Its diagnosis is difficult and often established with a delay causing a spread of infection. The diagnosis of tuberculosis infection is mainly based on immunological tests represented by the tuberculin skin test and detection of gamma interferon, while the diagnosis of pulmonary tuberculosis is suspected on epidemiological context, lasting general and respiratory symptoms, contrasting usually with normal lung examination, and a chest radiography showing suggestive lesions. The radioclinical feature may be atypical in patients with extreme ages and in case of immunodeficiency. Confirmation of tuberculosis is bacteriological. Conventional bacteriological methods remain the reference. Innovative tests using the technique of molecular biology have improved the diagnosis of tuberculosis in terms of sensitivity and especially speed. However, those techniques are of limited use.

Tuberculosis is a contagious disease caused by Mycobacterium tuberculosis. It represents, according to World Health Organization (WHO), one of the most leading causes of death worldwide. With nearly 8 million new cases each year and more than 1 million deaths per year, tuberculosis is still a public health problem. Despite of the decrease in incidence, morbidity and mortality remain important partially due to co-infection with human immunodeficiency virus and emergence of resistant bacilli. All WHO regions are not uniformly affected by TB. Africa's region has the highest rates of morbidity and mortality. The epidemiological situation is also worrying in Eastern European countries where the proportion of drug-resistant tuberculosis is increasing. These regional disparities emphasize to develop screening, diagnosis and monitoring to the most vulnerable populations. In this context, the Stop TB program, developed by the WHO and its partner's, aims to reduce the burden of disease in accordance with the global targets set for 2015.

Tuberculosis (TB) is still being endemic in our country. Time until management determines both evolution and prognosis of this condition. The aim of this work is to evaluate the delay in diagnosis of TB in a respiratory unit from a university hospital series. The authors conducted a cross-sectional study including patients with pulmonary TBC and/or pleural. An evaluation of time management was conducted from the beginning of symptoms and various consultations with reference to the date of hospitalization and treatment set up. One hundred patients were included (pulmonary TB: 68 cases, pleural TB 23 cases, miliary pulmonary TB: 4 cases, pulmonary TB associated with other extrathoracic locations: 5 cases). The mean time of patient delay and total delay institution were respectively 43.6, 25.7 and 69.3 days. Variables responsible for long delays were: number of consultations more than 3 before hospitalization, empirical antibiotic therapy, of a regional hospital first consultation and the presence of extra-respiratory impairment. The patient delay was considered long. A reorganization of the TB control program, in particular by partial decentralization of care and health education is imperative in order to improve the quality of tuberculosis management in our country.

Allergic rhinitis (AR) and asthma represent global health problems for all age groups. Asthma and rhinitis frequently coexist in the same subjects. Allergic Rhinitis and its Impact on Asthma (ARIA) was initiated during a World Health Organization workshop in 1999 (published in 2001). ARIA has reclassified AR as mild/moderate-severe and intermittent/persistent. This classification closely reflects patients' needs and underlines the close relationship between rhinitis and asthma. Patients, clinicians, and other health care professionals are confronted with various treatment choices for the management of AR. This contributes to considerable variation in clinical practice, and worldwide, patients, clinicians, and other health care professionals are faced with uncertainty about the relative merits and downsides of the various treatment options. In its 2010 Revision, ARIA developed clinical practice guidelines for the management of AR and asthma comorbidities based on the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) system. ARIA is disseminated and implemented in more than 50 countries of the world. Ten years after the publication of the ARIA World Health Organization workshop report, it is important to make a summary of its achievements and identify the still unmet clinical, research, and implementation needs to strengthen the 2011 European Union Priority on allergy and asthma in children.

OBJECTIVE: To report an atypical case of orbital inflammatory pseudotumor associated with optic neuritis revealing Behçet's disease. CASE REPORT: A 37-year-old man was worked up for headache and progressive decreased bilateral visual acuity most profound in the left eye. Initial ophthalmologic exam was without abnormal findings. Orbital CT scan and MRI appeared consistent with orbital inflammatory pseudotumor involving the left lateral rectus muscle (orbital myositis). The patient was treated with oral corticosteroids, but clinical response was incomplete. Follow-up ophthalmologic exam revealed acute inflammatory right optic neuritis (visual acuity: 5/10, papillitis on fundus exam and papillary edema on fluorescein angiography) and persistence of left orbital myositis. The diagnosis of Behçet's disease with ocular complications was made on the basis of recurrent oral ulcers, scars from genital ulcerations and pseudofolliculitis. It was decided to treat the patient with a bolus of IV methylprednisolone for 3 consecutive days, followed by oral prednisolone and cochicine, leading to stabilization of the ocular manifestations. CONCLUSION: To our knowledge, this is the first report of such an association leading to a diagnosis of Behçet's disease. The coexistence of these two manifestations as well as the contralateral nature of the involvement speaks to the pathogenic mechanism of these complications (systemic vasculitis).

Concepts of disease severity, activity, control and responsiveness to treatment are linked but different. Severity refers to the loss of function of the organs induced by the disease process or to the occurrence of severe acute exacerbations. Severity may vary over time and needs regular follow-up. Control is the degree to which therapy goals are currently met. These concepts have evolved over time for asthma in guidelines, task forces or consensus meetings. The aim of this paper is to generalize the approach of the uniform definition of severe asthma presented to WHO for chronic allergic and associated diseases (rhinitis, chronic rhinosinusitis, chronic urticaria and atopic dermatitis) in order to have a uniform definition of severity, control and risk, usable in most situations. It is based on the appropriate diagnosis, availability and accessibility of treatments, treatment responsiveness and associated factors such as comorbidities and risk factors. This uniform definition will allow a better definition of the phenotypes of severe allergic (and related) diseases for clinical practice, research (including epidemiology), public health purposes, education and the discovery of novel therapies.
