Abstract Spindle cell hemangioma (SCH) is a benign vascular tumour, first identified by Weiss and Enzinger in 1986. Habitually, the SCH affects almost exclusively the dermis and subcutaneous tissues of distal extremities. So far, only 2 cases have been described in the lung. We describe herein the third case of SCH occurring in the lung in a 47 year‐old woman. The patient was successfully treated by right lower lobectomy. The histopathological and immunohistochemistry examination of the excised tumour leads to the definitive diagnosis. Our case is instructive by its different clinical and radiological presentation compared to the previous two cases.

Pulmonary hydatic cyst, children, giant cyst ,Medicine - Abstract
Hydatid disease is still endemic in Tunisia. It is mostly seen in young people less than 40 years and children are affected in one third of cases. The lungs are the predominant location in children. Our study aims to define the particularities of children PHC's (pulmonary hydatic cyst) management, the characteristics of giant cyst and to study predictive factors of complications. We included retrospectively 105 children with PHC followed between 1999 and 2019. Patients were aged less than 16 years with surgically confirmed diagnosis of PHC. Two groups of cysts were defined: giant cysts which were 10 cm across or more, and no giant cysts.The sex-ratio was 1,38 with a mean age of 10.5±3 years. The symptomatology was dominated by cough (59%), thoracic pain (51%) and hemoptysis (46%). Giant cysts were observed in 24 (22.9%) patients. Dyspnea (29% vs 5% p0.05) and in giant cysts (41% vs 18% p0.05). In endemic regions, the diagnosis of PHC in children should be based on the combination of thoracic radiography and ultrasonography which are effective, not costly, safe and accessible. Complicated and giant PHC cause lung damage leading to extensive parenchymal resection. They are more associated with post-operative complications prolonging hospital stay and increasing expenses.

Background: Asthma is an immunological disorder in which T helper 2 (Th2)-type cells and inflammatory cytokines have a prominent role in its pathogenesis. B- and T-lymphocyte attenuator (BTLA), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed death 1 (PD-1) are co-inhibitory receptors that regulate T cell activation. Objective: In the present study of asthmatic patients we measured the soluble isoforms of BTLA (sBTLA), CTLA-4 (sCTLA-4) and PD-1 (sPD-1) in induced sputum fluid with the aim to evaluate their utility as responsible for exacerbation. Methods: Eighty patients with asthma and 30 healthy controls (HC) were included in the study. Sputum fluid concentrations of sBTLA, sCTLA-4 and sPD-1 were measured with ELISA. Comparisons were made with Mann-Whitney U test and correlations with IL-17, IL-26 levels and FEV1 (%) were assessed with Spearman’s Rank correlation test. Results: sBTLA levels were significantly higher in the severe and moderate asthmatic patients compared to healthy controls. Significant differences were observed between severe and moderate asthmatics (p < 0.0001). No significant differences were found between mild asthmatics and healthy controls (p = 0.799). Soluble PD-1 levels were higher in severe and moderate asthmatic patients compared to HC and no significant difference was observed between these two asthmatic groups (p = 0.124). Mild asthmatics and control subjects expressed similar sPD-1 levels (p = 0.856). Soluble CTLA-4 was exclusively expressed in certain severe asthmatic patients. IL-17 inflammatory cytokine was significantly correlated with BTLA and sPD-1. IL-17 and IL-26 cytokines were highly expressed in sputum asthmatic groups compared to sputum from HC. Severe asthmatic group was characterized by the highest levels of both IL-17 and IL-26 mediators. Soluble BTLA correlates positively with IL-17 (r = 0.817; p < 0.0001) and IL-26 (r = 0.805; p < 0.0001) inflammatory cytokines. IL-17 and IL-26 levels were associated with the asthma clinical severity from severe to mild asthma (p < 0.0001). The inflammatory cytokines IL-17 and IL-26 were positively correlated with the percentages of macrophages, PNN and FEV1 (%). Conclusion: Here, we provide the first report on the increased expression of sBTLA and sPD-1 in induced sputum of severe asthmatics. IL-26 and IL-17 appeared as a novel proinflammatory axis. Both sBTLA and sPD-1 might be involved in the pathogenesis of asthma and were associated with a poor prognosis.

Pulmonary hamartomas are the most common benign tumors of the lung in adults. They are usually asymptomatic because of their small size and their slow-growing character. We report the case of a 5-year-old child presenting with a giant lung mass causing recurrent right pneumonia. Surgical resection with middle lobectomy was performed. Final histology revealed pulmonary hamartoma with predominant adenofibromatous and lipomatous differentiation.

General Engineering - Abstract
_Background:_ Asthma is an airway disorder where inflammatory cytokines are partly responsible for exacerbating the disease. Interleukin (IL)-32, generally referred to as natural killer cell (NK4) transcript 4, is described as an immunoregulator involved in the stimulation of anti-/pro-inflammatory cytokines. The abnormal presence of IL-32 has been observed during inflammatory diseases, particularly in asthma. This study aims to characterize IL-32 in the inflammatory process in patients with severe asthma. _Methods:_ IL-32 and IL-1β levels in the supernatant of induced sputum obtained from 59 asthma patients (mild: 20 patients; moderate: 20 patients; severe: 19 patients) were measured using ELISA. Sputum IL-32 mRNA expression was measured by RT- PCR. _Results:_ Sputum IL-32 was significantly elevated at the protein (_p= 0.00019_) and mRNA expression (_p < 0.0001_) in asthmatics compared to non-asthmatic controls. IL-32 was elevated in severe asthmatic patients (_p < 0.0001_) compared to mild-moderate asthma. Severe asthmatics allergic to house dust mites expressed higher sputum IL-32 levels than severe asthmatics without allergy (_p = 0.0001_). A significant association was found between sputum IL-32 and IL-32 mRNA (r =0.531_; p = 0.0159_) in severe asthma. In the same way, sputum IL-1β and IL-32 were significantly correlated (r = 0.476; _p = 0.0337_). _Conclusion:_ The level of IL-32 in induced sputum may be associated with asthma severity.

Objective Asthma inflammation is a complex pathway involving numerous mediators. Interleukin-26 (IL-26), a member of the IL-10 cytokine family, is abundant in human airways and induces the production of proinflammatory cytokines. Our aim was to investigate the possible role of IL-26 in severe asthma. We analysed the expression of IL-26 in severe asthma both in peripheral blood and induced sputum. Patients and methods A total of 50 adult women with severe asthma were recruited and compared to 30 healthy controls (HC). Serum and sputum fluid (SF) levels of IL-26 and IL-17 were defined by ELISA. IL-26 mRNA expression and IL-26 protein were analysed using RT-PCR and Western blot. In vitro, we studied the effect of recombinant IL-26 (rIL-26) and SF-IL-26 on cultured CD4+ T cells and monocytes, comparing patients and controls. Results Concentrations of IL-26 are higher in serum and induced sputum of asthmatic patients than in HC. Moreover, IL-26 protein and mRNA expression were significantly elevated in asthma sputum cells compared to PBMCs. We observed a positive correlation between body mass index (BMI) and sputum fluid IL-26, while the correlation between IL-26 and lung function tests (FEV1% and FEV1/FVC ratio) was negative. IL-17A was highly expressed in SF and correlated positively with IL-26. In patients' sputum IL-26 and IL-17A were significantly associated with neutrophils. Stimulation of cultured CD4+ T cells with monocytes by recombinant IL-26 promoted the generation of RORγt+ Th17+ cells inducing the production of IL-17A, IL-1β, IL-6 and TNF-α cytokines. IL-26 expressed in SF was biologically active and induced IL-17 secretion in the presence of IL-1β and IL-6 cytokines. Conclusion These findings show that IL-26 is highly produced in asthmatic sputum, induces pro-inflammatory cytokine secretion by monocytes/macrophages, and favours Th17 cell generation. IL-26 thereby appears as a novel pro-inflammatory cytokine, produced locally in the airways that may constitute a promising target to treat asthma inflammatory process.

Since the discovery of COVID-19 in December 2019, many key questions were raised on the potential relationship between eosinophil count and the course and severity of COVID-19. Evaluate the value of eosinophil count (EC) on admission as a predictive marker of severity, ICU transfer and death in Covid-19 patients Retrospective study conducted from March 2020 to January 2021 in the pulmonary department B of Abderrahmen Mami hospital on confirmed COVID-19 pneumonia. We compared the clinical data, lab findings, including inflammatory markers, radiological findings, course and severity (mortality, ICU admission, and need for mechanical ventilation) in 2 groups: patients with eosinophilia (G1) to those without eosinophilia (G2). One hundred ninety six cases of COVID-19 were included in our study, The median age was 61,32±2,5 years. The sexe-ratio was 1,8. The most common comorbidities were hypertension (46%),diabetes(40%) and obesity(32%). Laboratory tests revealed that 18.7 % had mild eosinophilia (500 Patients with eosinophilia had milder clinical course and better disease outcomes. This protective role of eosinophils needs to be validated by further prospective studies.

Background: Flexible bronchoscopy (FB) is mainly used to diagnose foreign body aspiration. Its use in a removal purpose is still controversial. Our study aimed to report our experience in airway foreign bodies (AFB) extraction via flexible bronchoscopy. Methods: We conducted a retrospective study that included medical records of children diagnosed with AFB in the pediatric department of Abderrahman Mami Hospital, between January 2014 and December 2019. Results: A total of 64 children were included (62%). The mean age was 29 months [9-108]. Clinical context was suggestive of foreign body inhalation in 46 infants (71%). AFB were found in the right bronchial tree on 36 occasions, in the left on 28 and beyond the upper bronchus in 36 children. AFB were inorganic in 13 cases (including 2 scarf pins).The flexible bronchoscopy was performed through the laryngeal mask airway in 44 infants and after intubation in the other cases. Removal was successful in 59 children (92%). Rigid bronchoscopy was required in 2 cases and surgery in 1 case. Two infants expectorated the AFB after the procedure. There were no complications except laryngeal edema with transient oxygen desaturation in two children (3%). Conclusion: When done by an experienced team, flexible bronchoscopy allows an efficient and safe interventional management of airway foreign body.

On 2 March 2020, Tunisia has reported the first confirmed case of COVID-19. Since then, the disease has affected about 700 persons in the country. The purpose of our study was to report epidemiological, clinical, radiological and therapeutic features of patients with 2019-nCoV infection admitted in the pneumology department.We extracted the data of the consequetive 20 patients managed in the department of pneumology B at Abderrahmen Mami hospital, from March, 26 to April, 8, 2020.The median age was 61 years old [41-85]. There were 9 men and 11 women. Underlying disorders were observed in 16 patients (80%). Five patients were health care workers. Three patients did not have any known exposure. Common symptoms included fever (100%), shortness of breath (70%) and cough (70%). Computed tomography scans showed bilateral ground glass opacities in 7/9 cases. Fifteen patients received both chloroquine and azithromycin. Fourteen patients (70%) were discharged before April, 8, 2020. Reported complications were: hypokalemia (3 cases), pulmonary embolism (2 cases) and QT prolongation (1 case). One patient died from acute cardiac injury.Knowing the different aspects of moderate and severe forms of the disease can contribute to advance in infection control strategies.

Background: Asthma is an immunological disorder in which T helper 2 (Th2)-type cells and inflammatory cytokines have a prominent role in its pathogenesis. B- and T-lymphocyte attenuator (BTLA), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed death 1 (PD-1) are co-inhibitory receptors that regulate T cell activation. Objective: In the present study of asthmatic patients we measured the soluble isoforms of BTLA (sBTLA), CTLA-4 (sCTLA-4) and PD-1 (sPD-1) in induced sputum fluid with the aim to evaluate their utility as responsible for exacerbation. Methods: Eighty patients with asthma and 30 healthy controls (HC) were included in the study. Sputum fluid concentrations of sBTLA, sCTLA-4 and sPD-1 were measured with ELISA. Comparisons were made with Mann-Whitney U test and correlations with IL-17, IL-26 levels and FEV1 (%) were assessed with Spearman’s Rank correlation test. Results: sBTLA levels were significantly higher in the severe and moderate asthmatic patients compared to healthy controls. Significant differences were observed between severe and moderate asthmatics (p < 0.0001). No significant differences were found between mild asthmatics and healthy controls (p = 0.799). Soluble PD-1 levels were higher in severe and moderate asthmatic patients compared to HC and no significant difference was observed between these two asthmatic groups (p = 0.124). Mild asthmatics and control subjects expressed similar sPD-1 levels (p = 0.856). Soluble CTLA-4 was exclusively expressed in certain severe asthmatic patients. IL-17 inflammatory cytokine was significantly correlated with BTLA and sPD-1. IL-17 and IL-26 cytokines were highly expressed in sputum asthmatic groups compared to sputum from HC. Severe asthmatic group was characterized by the highest levels of both IL-17 and IL-26 mediators. Soluble BTLA correlates positively with IL-17 (r = 0.817; p < 0.0001) and IL-26 (r = 0.805; p < 0.0001) inflammatory cytokines. IL-17 and IL-26 levels were associated with the asthma clinical severity from severe to mild asthma (p < 0.0001). The inflammatory cytokines IL-17 and IL-26 were positively correlated with the percentages of macrophages, PNN and FEV1 (%). Conclusion: Here, we provide the first report on the increased expression of sBTLA and sPD-1 in induced sputum of severe asthmatics. IL-26 and IL-17 appeared as a novel proinflammatory axis. Both sBTLA and sPD-1 might be involved in the pathogenesis of asthma and were associated with a poor prognosis.

Poor control in patients with difficult-to-treat asthma might be due to several factors, including poor adherence and undertreated asthma co-morbidities. After an assessment addressing these issues, only few patients still need targeted therapy. We aimed to evaluate the effect of a multidimensional intervention in improvement asthma control in patients with difficult asthma. Fifty patients with difficult asthma were prospectively included in this study conducted in AbderrahmenMami hospital between March 2018 and September 2018. Clinical, biological and functional characteristics were collected. Then, coexisting conditions (poor adherence, allergens exposure, chronic rhinosinusitis, gastro-oesophageal reflux, obesity, obstructive sleep apnea syndrome, anxiety and depression)were identified and managed. Finally, asthma treatment was optimized. Patients were aged between 25 and 70 years with 54% of them being atopic and 78% reporting an adult onset of their asthma. Median asthma duration was 23years. Thirty-two patients had three or more comorbidities, with chronic rhinosinusitis(72%), anxiety(68%)and obesity(54%) being the most prevalent. Poor adherence to treatment was found in 8patients. Different treatments were prescribed:nasal corticosteroid therapy(66%), proton pump inhibitors(24%) and anti-depressants(8%). CPAP was indicated for 4 patientes with severe OSAS. Formoterol was added to 11patients, tiotropium to 8 and montelukast to 6. We observed a significant improvement in asthma control(mean ACTscore changed from 15,7to 20,2,p=0,0001). An increase in FEV1 of more than120ml was observed in54%of patients. A multidimensional intervention in a specialized center improves difficult asthma control.

Objective Asthma inflammation is a complex pathway involving numerous mediators. Interleukin-26 (IL-26), a member of the IL-10 cytokine family, is abundant in human airways and induces the production of proinflammatory cytokines. Our aim was to investigate the possible role of IL-26 in severe asthma. We analysed the expression of IL-26 in severe asthma both in peripheral blood and induced sputum. Patients and Methods A total of 50 adult women with severe asthma were recruited and compared to 30 healthy controls (HC). Serum and sputum fluid (SF) levels of IL-26 and IL-17 were defined by ELISA. IL-26 mRNA expression and IL-26 protein were analysed using RT-PCR and Western blot. In vitro, we studied the effect of recombinant IL-26 (rIL-26) and SF-IL-26 on cultured CD4+ T cells and monocytes, comparing patients and controls. Results Concentrations of IL-26 are higher in serum and induced sputum of asthmatic patients than in HC. Moreover, IL-26 protein and mRNA expression were significantly elevated in asthma sputum cells compared to PBMCs. We observed a positive correlation between body mass index (BMI) and sputum fluid IL-26, while the correlation between IL-26 and lung function tests (FEV1% and FEV1/FVC ratio) was negative. IL-17A was highly expressed in SF and correlated positively with IL-26. In patients’ sputum IL-26 and IL-17A were significantly associated with neutrophils. Stimulation of cultured CD4+ T cells with monocytes by recombinant IL-26 promoted the generation of RORγt+ Th17+ cells inducing the production of IL-17A, IL-1β, IL-6 and TNF-α cytokines. IL-26 expressed in SF was biologically active and induced IL-17 secretion in the presence of IL-1β and IL-6 cytokines. Conclusion These findings show that IL-26 is highly produced in asthmatic sputum, induces pro-inflammatory cytokine secretion by monocytes/macrophages, and favours Th17 cell generation. IL-26 thereby appears as a novel pro-inflammatory cytokine, produced locally in the airways that may constitute a promising target to treat asthma inflammatory process.

The interleukin-26 (IL-26), a member of the IL-10 family is one of the latest discovered cytokines which contributes in numerous chronic autoimmune and inflammatory disorders. In the current case-control study, we investigated the distribution of three IL-26 single nucleotide polymorphisms (SNPs) (rs7134599, rs2870946rs1558744) in 440 Tunisian adults via Taqman genotyping assay. The presence of rs7134599 and rs1558744 polymorphisms considerably reduced the risk of developing asthma while the rs7134599 AA [OR = 0.40, CI: 0.23-0.70] and AG [OR = 0.50, CI (0.32-0.76)] genotypes protected against the asthma risk. The rs7134599 A allele was correlated with a lower risk of developing severe asthma (p 0.001) while that of the rs2870946 CC genotype was associated with a higher risk of developing asthma in smoking patients (p 0.001). In addition, we measured the IL-26 levels in the serum by an Enzyme-linked-Immunosorbent Assay (ELISA). During the analysis, we found that IL-26 serum levels were incredibly increased in asthmatic patients compared to the healthy controls. Our study revealed a significant association of IL-26 gene polymorphisms with asthma for the first time which can serve as biomarkers for asthma in the Tunisian population. The significant increase of IL-26 serum protein levels in asthma patients suggested a major role of IL-26 in asthma phenotypes.

Background Lungs are the second most common site for hydatid disease after the liver. Giant hydatid cyst (GHC) of the lung is a special clinical entity in children and is related to higher lung tissue elasticity. Aim To compare clinical and imaging features, types of surgical interventions, and postoperative complications in pulmonary GHC and non-giant pulmonary hydatid cysts (NGHC) in children. Methods A retrospective study was undertaken. The data analyzed were taken from medical records of children with pulmonary hydatid cyst (PHC) hospitalized in a pulmonary department in Tunisia between January 2004 and February 2019. Cysts were divided according to their size into GHC ( ≥10 cm) and NGHC ( Results In the study period, 108 PHC were recorded in 84 children. GHC accounted for 21 (19.4%) and NGHC for 87 (80.6%). The median of age of the children was 11 years (IQR 1–9, IQR 3–14) and the mean age was 11.6 years (10.5 in GHC vs. 11.4 years in NGHC). Hemoptysis was found in 25% of the GHC group vs. 48.4% of the NGHC group (P = 0.27). Cysts were multiple in 23.8% of cases and predominated in the right in 64.3% of cases and in the inferior lobes in 71.4% of the cases. GHCs were less frequently complicated (60% vs. 78.1% in NGHC, P ≤ 0.11), although not significantly. Parenchymal resection was realized in 50% of GHC vs. 18.8% of NGHC (P = 0.006). No significant difference was found in postoperative complications between the two groups and there was no recurrence in either group. Conclusion GHC is a special clinical entity in children. It requires major surgery with parenchymal resection, and therefore early diagnostic and therapeutic management is warranted.

Iatrogenic tracheal stenosis is a severe late complication of tracheal intubation and tracheotomy. Its features have a strong impact on the therapeutic strategy. The records of 73 patients managed for iatrogenic tracheal stenosis in the department of thoracic surgery ofAbderrahmenMami hospital, between January 1995 and December 2015, were reviewed in order to study the clinical, radiological and therapeutic features of this disease. The mean age of the patients was 31years (10 to 64 years). All the patients reported a past history of intubation, associated with tracheotomy in 34%of the cases. Mean intubation time was 12days. The mean interval between extubation and the diagnosis was 106days. Fiberoptic bronchoscopywas performed in 67cases(92%). It showed a circumferentialstenosis in87.6% of the cases and a complex stenosis in12%. Chest CT scan or MRI was performed in95.5% of the cases. The mean distance between the stenosis and vocal cords was 3.17 cm[1-7.5cm]. The mean length of the stenosis was 2.2 cm. Thirteen patients(17.8%) underwent endoscopic treatment before surgery(dilatation 8cases, laser treatment 5 cases)with good immediate results in 53%of the cases. In our study, all the patients underwent tracheal resection and reconstruction. Postoperative complications were observed in 10.9%of cases. One patient died in the immediate postoperative period secondary to hemorrhage. The follow-up periods ranged from 2 to 69 months and showed a recurrence in one patient. Tracheal stenosis is a serious cause of morbidity and mortality in patients who underwent intubation, tracheotomy, or both. Its management is challenging and requires a multidisciplinary team. Its features have to be well analyzed in order to adopt the suitable therapeutic choice.

Introduction Les exacerbations d’asthme constituent une cause majeure de morbidite et d’elevation des couts des soins lies a cette pathologie. La determination des facteurs associes a ces exacerbations permet de prevenir leur survenu. L’objectif de notre travail etait d’identifier les caracteristiques cliniques, inflammatoires et fonctionnelles des patients exacerbateurs frequents chez des asthmatiques severes. Methodes Etude transversale ayant interesse 50 patientes suivies dans une consultation specialisee d’asthme severe au pavillon B de l’hopital Abderrahmen-Mami de l’Ariana entre mars et juin 2018. Nous avons compare le profil clinique, inflammatoire et fonctionnel des patientes ayant un nombre moyen d’exacerbations ≥ 3/an par rapport aux autres patientes. Resultats Parmi les 50 asthmatiques severes, 38 faisaient en moyenne 3 exacerbations/an ou plus(76 %). Il n’y avait pas de difference significative concernant l’âge moyen, l’atopie et le BMI moyen entre les deux groupes. La presence d’un reflux gastro-oesophagien, d’une rhino-sinusite chronique, d’un trouble anxieux ou d’un syndrome d’apnee obstructif du sommeil etaient liees a des exacerbations plus frequentes avec des p respectives egales a 0,0001, 0,007, 0,02 et 0,05. L’hypereosinophilie sanguine(PNE > 400/mm3)ainsi qu’un taux d’IgE > 100UI/L etaient plus frequents chez les patientes qui faisaient plus d’exacerbations(p = 0,04 et 0,03 respectivement). Il n’y avait pas de difference significative concernant le FeNO(p = 0,5)ni l’hypereosinophilie dans les expectorations induites(p = 0,9) dans les deux groupes. Il y avait plus d’obstruction reversible et de VEMS Discussion Les marqueurs inflammatoires(PNE,IgE)permettraient d’identifier les patients a risque d’exacerbation future. Les co-morbidites de l’asthme severe seraient responsables d’exacerbations plus frequentes. Leur controle pourrait prevenir ces exacerbations, surtout dans les pays ou les therapies ciblees ne sont pas disponibles.

Pulmonary and Respiratory Medicine - Abstract
Introduction Le tableau clinicoradiologique peut etre atypique au cours de la sarcoidose, ce qui implique une rigueur accrue dans les explorations afin d’eliminer les diagnostics differentiels surtout neoplasiques. Le recours a la mediastinoscopie aide souvent a mettre en evidence le granulome tuberculoide dans les adenopathies mediastinales. L’objectif de notre etude etait de definir le profil des patients chez qui le diagnostic de sarcoidose pulmonaire a ete retenu apres mediastinoscopie. Methodes Il s’agit d’une etude retrospective portant sur 66 patients suivis pour sarcoidose mediastino-pulmonaire entre janvier 2000 et decembre 2017 au service de pneumologie Ibn Nafiss de l’hopital Abderrahmene Mami de l’Ariana. Nous avons compare les donnees des patients qui ont eu une mediastinoscopie (groupe 1) a celles du reste des patients (groupe 2). Resultats Le diagnostic de sarcoidose a ete retenu apres mediastinoscopie chez 14 des 66 patients inclus (21,2 %). L’âge moyen dans ce groupe etait de 46 ans et le sex-ratio de 0,27. Il n’y avait pas de difference significative concernant la presence des signes fonctionnels respiratoires dans les deux groupes, mais il y avait plus de signes generaux dans le groupe qui a eu une mediastinoscopie (p = 0,006). L’atteinte radiologique de type II etait predominante dans les deux groupes (48 % versus 64 %, p = 0,28). Une lymphocytose au lavage bronchioloalveolaire etait moins frequente chez les patients du groupe 1 (55 % versus 75 %, p = 0,22). Les localisations extrathoraciques etaient plus retrouvees chez les patients qui n’ont pas eu de mediastinoscopie (32 % versus 21 %, p = 0,41). Les biopsies par mediastinoscopie avaient montre une lymphadenite tuberculoide sans necrose caseeuse dans tous les cas. Le diagnostic histologique de sarcoidose a ete retenu chez les patients du groupe 2 par : biopsie bronchique (28,7 %), biopsie labiale (12 %), biopsie d’une adenopathie peripherique (6 %), biopsie cutanee (3 %), biopsie hepatique (3 %) et biopsie pulmonaire transparietale (1,5 %). La tuberculose pulmonaire etait eliminee par la negativite des cultures de BK chez les patients des deux groupes. Conclusion La mediastinoscopie garde une place dans la prise en charge diagnostique de la sarcoidose, notamment dans les formes atypiques suggerant une tuberculose ou une etiologie tumorale.

Introduction Les accidents thromboemboliques sont plus frequents au cours des maladies cancereuses et constituent une des principales causes de deces chez ces patients. Le but de notre travail etait d’etudier la survenue d’evenements thromboemboliques chez nos patients suivis pour cancer bronchique. Methodes Nous avons realise une etude retrospective portant sur des dossiers de patients suivis au service de pneumologie Ibn Nafiss pour un cancer du poumon et qui ont presente une thrombose veineuse profonde (TVP) ou une embolie pulmonaire (EP) au cours de la periode allant de janvier 2004 a decembre 2017. Resultats Soixante-dix patients ont ete inclus avec une predominance masculine (64 hommes). L’âge moyen etait de 61 ans [36–83]. Le type histologique le plus frequent etait l’adenocarcinome (42,8 %) suivi du carcinome epidermoide (21,4 %). Le cancer bronchique etait metastase dans 82,8 % des cas. L’accident thromboembolique etait revelateur du cancer chez 16 patients (22,8 %). Vingt-huit patients etaient sous chimiotherapie au moment de la survenue de la thrombose (40 %). Dans 4 % des cas, il s’agissait d’une EP associee a une TVP, dans 53,2 % des cas d’une TVP seule et dans 42,8 % d’une EP seule. La decouverte de l’evenement thromboembolique etait fortuite chez 28 patients (40 %). L’evaluation du score de Geneve modifie a montre que 7 % des patients avaient un risque faible d’accident thromboembolique, 67,3 % un risque intermediaire et 25,7 % un risque fort. Tous les patients ont ete mis sous traitement anti-coagulant. Treize patients avaient presente des complications hemorragiques (18,5 %). La survie globale des patients a deux ans etait de 7 %. Conclusion Le type histologique, le stade et la chimiotherapie du cancer influencent le risque de survenue d’un evenement thromboembolique. Cette complication doit etre depistee et traitee afin d’ameliorer le pronostic a court terme.

Introduction L’asthme associe au syndrome de Widal est souvent considere comme un phenotype de debut tardif dont l’inflammation serait de type TH2. L’objectif de notre travail etait d’etudier les caracteristiques cliniques, inflammatoires et fonctionnelles de ces patients. Methodes Il s’agit d’une etude transversale incluant des patientes suivies pour asthme severe defini selon les recommandations de l’ATS/ERS 2014. La triade de Widal a ete retenue si l’asthme etait associe a une intolerance a l’aspirine et a la presence d’une polypose nasale. Les patientes ont eu une analyse des expectorations induites et une spirometrie avec un test de reversibilite. Resultats Le syndrome de Widal etait retenu chez 11 patientes. L’âge moyen etait de 55 ans [27–70 ans]. L’asthme etait a debut tardif chez toutes les patientes. La duree d’evolution moyenne de la maladie etait de 21 ans. Dix patientes avaient un antecedent d’asthme aigu grave, qui etait secondaire a la prise d’aspirine dans cinq cas. L’analyse des expectorations induites avaient montre une eosinophilie chez trois patientes (27,4 %) et une neutrophile chez une patiente (9 %). Le reste des patientes avait une expectoration paucicellulaire (63,6 %). L’asthme etait allergique chez les patientes eosinophiliques et chez une patiente paucicellulaire. La spirometrie etait normale chez deux patientes dont les expectorations etaient paucicellulaires. Ailleurs, elle avait montre un trouble ventilatoire obstructif reversible chez les patientes eosinophiliques et chez une patiente paucicellulaire, et une obstruction fixee chez la patiente neutrophilique et chez quatre patientes paucicellulaires. L’ACT moyen etait egal a 17. Conclusion L’asthme associe au syndrome de Widal est souvent difficile a controler malgre les fortes doses de corticotherapie inhalee et le recours frequent a la corticotherapie orale au long cours. Ceci pourrait etre explique par l’heterogeneite et le chevauchement des phenotypes chez ces patients.

Introduction La pneumopathie aigue communautaire (PAC) reste un motif frequent de consultation en pneumologie et constitue une cause majeure de morbidite et de mortalite. Le but de notre travail est d’etudier l’epidemiologie, les caracteristiques cliniques, paracliniques, microbiologiques, therapeutiques et evolutives des PAC admises dans notre service. Methodes Il s’agit d’une etude retrospective, descriptive dans laquelle nous avons analyse les dossiers de 113 patients hospitalises pour PAC bacterienne dans notre service sur une periode de 4 ans. Resultats Les taux d’hospitalisation les plus eleves etaient observes en hiver et au printemps avec un taux respectif de 27 % et de 33 %. Le score le plus utilise pour indiquer l’hospitalisation etait le CURB-65. L’age moyen de nos patients etait de 59,6 ans. Le sex-ratio etait egal a 2,2. Le motif de consultation le plus frequent etait la toux avec douleurs thoraciques dans 44 % des cas. La notion de prise d’antibiotiques avant l’hospitalisation etait constatee dans 49 % des cas. L’hypoxie etait le principal motif d’admission (32,7 % des cas). Tous nos patients avaient beneficie d’un bilan biologique inflammatoire et d’une radiographie thoracique de face. L’aspect radiologique le plus frequent etait une opacite alveolaire non systematisee. Cent-six cas avaient beneficie d’une recherche microbiologique (soit 93 % des cas), un germe etait isole dans 10 % des cas. L’antibiotherapie etait probabiliste dans la majorite des cas. Une monotherapie a base de betalactamines etait prescrite dans 67 % des cas. La duree moyenne de l’antibiotherapie etait de 17 ± 10 jours. L’evolution etait favorable dans la majorite des cas. Un transfert en reanimation medicale etait indique chez 3 patients. Nous avons deplore un deces. Conclusion Les PAC sont responsables d’une lourde morbi-mortalite. Le traitement antibiotique probabiliste doit etre instaure le plus rapidement et doit etre reevalue dans 48–72 heures afin de depister les complications a temps.

Pulmonary and Respiratory Medicine - Abstract
Introduction La dilatation des bronches (DDB) est une maladie chronique, d’etiologies variees. Son pronostic depend de l’etendue des lesions, de la precocite de prise en charge et du terrain. Methodes Etude retrospective incluant 142 patients suivis pour DDB, colliges sur une periode de 10 ans [janvier 2007 a decembre 2016]. Resultats La moyenne d’âge des patients etait de 52 ans [15–88 ans]. Le sex-ratio etait de 1,14. L’âge moyen de debut des symptomes etait de 48,4 ± 18 ans. Le delai moyen de consultation etait de 37 jours [2–180]. Les circonstances de decouverte etaient dominees par la toux (79 %), la dyspnee (63 %), la bronchorrhee (56,6 %) et l’hemoptysie (30,6 %). Les DDB etaient diffuses dans 71 % des cas. Le bilan etiologique a montre un antecedent de tuberculose pulmonaire dans 18,5 % des cas, un reflux gastro-œsophagien dans 8,5 % des cas, une maladie de systeme dans 6,5 % des cas et une dyskinesie ciliaire dans 4 % des cas. Tous les patients ont eu une kinesitherapie de drainage bronchique. Une antibiotherapie adaptee etait prescrite au cours des episodes de surinfection bronchique. Le traitement chirurgical etait indique dans 7,3 % des cas. L’evolution etait favorable chez 18,5 % des patients. Les complications les plus frequentes etaient les surinfections bronchiques (75,8 %) et l’hemoptysie (30,6 %). Vingt-quatre patients avaient developpe une insuffisance respiratoire chronique au cours du suivi (19,3 %). Conclusion La prise en charge des DDB necessite un bilan etiologique precis. Le traitement est chronique et base sur une antibiotherapie ciblee associee a une kinesitherapie respiratoire. La chirurgie doit etre discutee dans les cas localises.

Pulmonary and Respiratory Medicine - Abstract
Introduction La realisation d’un test d’effort n’est pas recommandee dans l’asthme. L’evaluation respiratoire se restreint a la spirometrie. Neanmoins, la dyspnee aux activites quotidiennes est un symptome frequemment rapporte chez les asthmatiques severes. L’objectif de notre etude etait de verifier si le test de marche de six minutes etait un bon indicateur dans l’evaluation de la dyspnee aux efforts quotidiens chez des asthmatiques severes. Methodes Il s’agit d’une etude transversale ayant inclus 42 patientes suivies pour asthme severe au pavillon B de l’hopital Abderrahmen Mami. Deux groupes ont ete identifies : les patientes ayant une dyspnee aux efforts quotidiens et celles qui ne rapportaient pas ce symptome. Toutes les patientes ont eu une spirometrie avec test de reversibilite et un test de marche de six minutes. Resultats Une dyspnee d’effort etait rapportee par 27 patientes a l’interrogatoire (64 %). L’âge moyen etait comparable dans les deux groupes (54 et 52 ans). Un IMC superieur a 30 kg/m2 etait present chez 70 % des patientes ayant une dyspnee aux efforts quotidiens versus 33 % dans le groupe sans dyspnee (p = 0,02). Le controle de l’asthme etait meilleur chez les patientes ne presentant pas une dyspnee d’effort (66 % versus 25 %, p = 0,007). La distance de marche parcourue moyenne etait de 473 metres (soit 81,7 % de la distance theorique). Une desaturation a ete trouvee chez 5 patientes (11,6 %). L’indice de Borg etait superieur a 3 a la fin du test chez 57 % des patientes. Il n’y avait pas de difference significative entre le groupe symptomatique de dyspnee d’effort et le reste des patientes concernant la distance moyenne parcourue (479 m versus 460 m), la desaturation (29 % versus 20 %, p = 0,49) et l’augmentation du score de Borg a la fin du test (62 % versus 60 %, p = 0,81). Le VEMS moyen etait de 64 % chez les patientes dont la distance de marche etait inferieure a 80 % de la valeur theorique et de 77 % chez les autres patientes (p = 0,26). Conclusion Le test de marche de six minutes permet de mettre en evidence un retentissement sur les capacites d’effort chez les asthmatiques severes, dependante de l’importance de l’obstruction. Cependant, la gene ressentie par les patients n’est pas correlee aux donnees du test de marche, mais associee a l’obesite.

Pulmonary and Respiratory Medicine - Abstract
Introduction Le diagnostic de la sarcoidose repose sur le tableau radio-clinique compatible, la mise en evidence de granulomes non caseeux et l’exclusion des autres causes de granulomatose. Methodes Afin d’evaluer notre demarche dans le diagnostic positif de la sarcoidose, nous avons mene une etude retrospective sur dossiers de patients suivis pour sarcoidose mediastino-pulmonaire au service de pneumologie Ibn Nafiss de l’hopital Abderrahmene Mami de l’Ariana, au cours de la periode allant de janvier 2000 jusqu’a decembre 2017. Resultats On a collige 66 patients (14 hommes et 52 femmes). L’âge moyen etait de 49,4 ans [21–76 ans]. Le delai moyen de consultation etait de 270 jours. La decouverte etait fortuite chez trois patients. La symptomatologie etait dominee par une toux chronique (60,6 %), une dyspnee d’effort (58,4 %), des douleurs thoraciques (30,7 %) et des signes generaux (21,8 %). La radiographie thoracique avait montre une atteinte de type 0 (0,03 % des cas), de type I (22,7 % des cas), de type II (51,5 %), de type III (10,6 %) et de type IV (12,12 %). Le scanner thoracique a montre des adenopathies mediastinales dans 87 % des cas. L’atteinte parenchymateuse la plus frequente etait des micronodules a distribution peribronchovasculaire (67 %des cas). Le lavage bronchioloalveolaire, fait dans 71,2 % des cas, avait montre une lymphocytose chez 43 % des patients. Le rapport CD4/CD8 etait superieur a 3,5 dans 21 % des cas. Tous les patients avaient des cultures de BK negatives dans les crachats et dans le liquide bronchique. Deux patients presentaient un syndrome de Lofgren (3 %). Un granulome tuberculoide etait trouve chez 73,8 % des patients. Le diagnostic histologique a ete fait par : biopsie bronchique (28,7 %), biopsie labiale (12 %), biopsie d’une adenopathie peripherique (6 %), biopsie cutanee (3 %), biopsie hepatique (3 %) et biopsie pulmonaire transparietale (1,5 %). Quatorze patients ont eu des biopsies chirurgicales sous mediastinoscopie (21,2 %). Le delai moyen de diagnostic positif etait de 64 jours. Conclusion La difficulte diagnostique de la sarcoidose reside dans le fait qu’il n’existe pas de tests diagnostiques specifiques. Ainsi, l’approche diagnostique est basee initialement sur des arguments cliniques, radiologiques et biologiques. Le granulome tuberculoide doit etre recherche par les biopsies des organes atteints et accessibles surtout dans les formes atypiques.

Pulmonary and Respiratory Medicine - Abstract
Introduction Le poumon represente, chez l’adulte, la deuxieme localisation la plus frequente de l’hydatidose. Le traitement de reference reste la chirurgie. La prophylaxie tient un role majeur en permettant d’interrompre le cycle parasitaire. Methodes une etude retrospective d’une serie de 50 cas d’hydatidose pulmonaire colliges durant une periode allant de janvier 2006 a decembre 2016. Resultats L’âge moyen de nos patients etait de 39 ans [20–39 ans]. La decouverte etait fortuite chez 4 patients. La symptomatologie pulmonaire etait revelatrice dans 92 % des cas dominee par la douleur thoracique (66 %) et la toux (58 %). La radiographie thoracique a objective un kyste unique dans 68 % des cas et multiple bilaterale dans 14 % des cas. L’association hydatique hepato-pulmonaire a ete retrouvee dans 18 % des cas. La chirurgie conventionnelle etait indiquee dans 92 % des cas et la chirurgie video-assistee dans 8 % des cas. Le traitement conservateur (kystectomie) etait adopte dans 98 % cas. Les kystes hydatiques multiples bilateraux ont ete operes en deux temps operatoires avec un intervalle de 1 a 2 mois. Le traitement de l’hydatidose abdominale associee a ete realise en deuxieme temps operatoire apres cure du kyste hydatique pulmonaire. Un seul geste chirurgical radical a ete note dans notre etude. On ne deplore aucun deces et on rapporte un seul cas de recidive. Dans notre etude, Le traitement antiparasitaire a base d’albendazole a ete instaure dans cinq cas : 3 patients ayant une hydatidose pulmonaire multiple, un patient inoperable en raison de son âge avance et de son etat respiratoire altere et 1 cas de rupture dans la plevre. Conclusion Dans l’hydatidose pulmonaire, le traitement chirurgical reste a ce jour le seul efficace. Le traitement medical est indique dans la forme multiple et bilaterale. Par ailleurs, la prophylaxie tient un role majeur en permettant d’interrompre le cycle parasitaire.

Pulmonary and Respiratory Medicine - Abstract
Introduction L’hydatidose thoracique est la deuxieme localisation apres le foie chez l’adulte, avec une atteinte le plus souvent pulmonaire. Cette pathologie constitue encore un probleme majeur de sante publique en Tunisie. Methodes Etude retrospective incluant 80 dossiers d’hydatidose pulmonaire sur une periode de 10 ans (2006–2016). Resultats Il y avait 60 hommes et 20 femmes avec un âge moyen de 30 ans. La notion de contage hydatique a ete trouvee dans 60 % des cas. La decouverte etait fortuite dans 30 % des cas. La radiographie thoracique a montre une opacite ronde bien circonscrite dans 70 % des cas, un niveau hydro-aerique avec un aspect de membrane flottante dans 20 % des cas et un lâcher de ballon dans 10 %. La TDM thoracique a confirme la densite hydrique dans 80 % des cas, a permis une meilleure etude de la paroi et le niveau hydro-aerique, a objective d’autres kystes et a etudie le parenchyme pulmonaire sous-jacent. La localisation hepatique a ete trouvee dans 20 % des cas. La bronchoscopie souple a visualise un aspect typique de membrane hydatique dans 20 % des cas. La serologie hydatique etait positive dans 80 % des cas. Le traitement a ete chirurgical dans 90 des cas. En cas de multiples kystes hydatiques, les patients ont ete mis sous traitement medical (albendazole). L’evolution etait favorable. La recidive etait notee dans 10 % des cas. Conclusion La maladie hydatique est une maladie parasitaire cosmopolite encore frequente dans notre contexte. Elle represente un probleme de sante publique. La chirurgie est le meilleur traitement. Des mesures preventives sont toujours necessaires.

Pulmonary and Respiratory Medicine - Abstract
Introduction L’inhalation de corps etrangers (CE) chez l’enfant est un accident grave qui reste frequent dans notre pays. Sa prise en charge est le plus souvent endoscopique, mais pour certains enfants l’extraction est chirurgicale les exposant a une morbidite non negligeable. Le but de notre travail est de rapporter notre experience entre 2002 et 2016 et de comparer l’evolution de la prise en charge entre deux periodes (2002 a 2011 et 2011 a 2016). Methodes Pour cela nous avons realise un travail retrospectif ayant interesse146 enfants ayant inhale des CE hospitalises au Pavillon B de l’hopital Abderrahmen-Mami de l’Ariana. Resultats L’âge moyen etait de 30,5 mois (6–192) avec un sexe ratio de 1,97. Les motifs de consultation etaient representes par les infections respiratoires basses recidivantes ou trainantes dans 30,9 % des cas, une dyspnee sifflante dans 20,1 % des cas, un syndrome de penetration est rapporte dans. Le delai du etait superieur a 30 jours dans 22,4 % des cas. L’extraction a ete faite par fibroscopie chez 36 enfants (24,6 %). L’extraction chirurgicale etait necessaire chez 16 enfants avec une pneumonectomie (3 enfants) ou une lobectomie (7 enfants) faites devant la destruction parenchymateuse. En comparant les deux periodes entre 2002 a 2011 et 2011 a 2016, nous avons constate que le nombre des enfants pris en charge a evolue allant de 76 en10 ans vs. 70 en 6 ans. Les CE les plus frequents etaient les glibettes alors que durant les 6 dernieres annees il y avait plus d’amandes. L’extraction par fibroscope est devenue plus frequente grâce a l’utilisation d’une nouvelle methode qui est l’utilisation d’un masque larynge permettant l’utilisation de fibroscope adulte, et ainsi, de pinces de plus gros calibre. L’extraction par le fibroscope etait faite chez 11 enfants durant la premiere periode et chez 25 enfants durant les 6 dernieres annees dont10 par masque larynge. Le nombre d’extractions chirurgicales est passe de12 en10 ans a 4 en 6 ans. Par ailleurs, les delais du diagnostic n’ont pas change. Un delai de plus de 30 jours a ete note dans 23,8 % des cas durant la premiere periode et dans 21 % des cas durant les 6 dernieres annees. Conclusion L’amelioration des techniques d’anesthesie et d’endoscopie dans la prise en charge des CE intrabronchiques chez l’enfant permet d’eviter le recours a la chirurgie. Toutefois, le manque de sensibilisation des parents ainsi que des medecins de premiere ligne est a l’origine du retard de prise en charge de ces accidents.
