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. She has no history of endotracheal intubation or granulomatous disease. Flexible fiberoptic bronchoscopy and thoracic computed tomography revealed double tracheal stenosis. The patient had rigid bronchoscopy; the upper tracheal stenosis was dilated with insertion of a silicone airway stent at the level of the distal stenosis. The diagnosis of idiopathic stenoses was made according to the clinico-radiological features. Symptoms were completely relieved and no recurrence was observed after one year of follow-up. This case highlights the importance of clinical suspicion and early diagnosis of Idio-SS in patients with unexplained wheezing and dyspnea. It also illustrates the role of endoscopic procedures in this situation.

Assessment Tools for Pulmonary Involvement in Patients with Ankylosing Spondylitis: Is Diaphragmatic Ultrasonography Correlated to Spirometry?

Objective: Spondyloarthritis (SpA) is a chronic inflammatory rheumatic disease that can lead to spinal ankylosis and consequently, restrictive pulmonary dysfunction. Thus, the present study aimed to assess the accuracy of diaphragm ultrasound compared to spirometry in the screening of restrictive pulmonary disorders in radiographic SpA patients. Methods: We conducted a cross-sectional study of 50 patients with radiographic SpA, over six months. Sociodemographic data, clinical characteristics of the disease, as well as biological, radiological, and therapeutic data, were collected. Spirometry and diaphragm ultrasound were performed. Results: The mean age of the study participants (N= 50) was 42.7±11 years [range: 25-66] with male predominance (N= 41). Spirometry showed a restrictive disorder in 32% of cases. The mean chest expansion (CE) value was 3.9±1.81cm [range: 1-9] with a median of 4 cm. A pathological value (<5cm) was observed in 72% of cases. A significant positive correlation was found between the right inspiratory diaphragmatic thickness and forced vital capacity (FVC) (r= 0.36; p = 0.02) and the supine FVC (r=0.29; p = 0.04). The left inspiratory diaphragmatic thickness was correlated with the percentage of the FVC decrease (r= 0.35; p = 0.01) defined as the percentage of difference between FVC and supine FVC. The right expiratory diaphragmatic thickness was associated with the FVC (r=0.32; p = 0.02). A significant positive correlation was found between the CE and the presence of B lines (r=0.32; p = 0.02), but not between the CE and the FVC. Conclusion: The present study showed that diaphragm ultrasonography is correlated with spirometric findings in radiographic SpA patients. Further studies are required to assess its reliability, specificity, and sensitivity in this pathology.

Precision of pleural puncture sites using thoracic ultrasound.

INTRODUCTION: Lung ultrasound (LUS) has been recommended by the British Thoracic Society as a standard of care before performing pleural procedures since 2010. Indeed, the choice of the puncture site based only on physical examination and chest x-ray can lead to complications. The aim of this study was to compare the accuracy of pleural puncture sites using LUS as opposed to clinical examination. METHODS: An evaluative prospective study including 43 patients hospitalized in the pneumology department at the Military Hospital of Tunis was conducted between January and November 2021.Pleural puncture sites were proposed by two groups involving 'senior' and 'junior' physicians, classified according to their experience and grades, based on the clinical examination and the chest x-ray findings. The accuracy of the proposed sites was then verified by an ultrasound-qualified "expert" using LUS. RESULTS: The mean age was 60 ± 17 years. LUS revealed the presence of pleural effusion in 88% of the cases (n=38). Differential diagnosis was therefore excluded in 12% of the cases (n=5), including pleural thickening (5%, n=2) and atelectasis (7%, n=3). Compared to LUS, clinical examination and chest x-ray had lower sensitivities, estimated at 74% and 83%, respectively. The clinical identification error rate was significantly higher in junior (77%) compared to senior physicians (49%) (p<0.05). LUS prevented possible accidental organ puncture in 36% of the cases (n=31). The risk factors associated with inaccurate clinical site selection included right-sided effusion and minimal pleural effusion on chest radiography, with an estimated relative risk (RR) of 1.44 [CI95%:0.56-3.72] and 1.82 [CI95%:0.52-6.40], respectively. The experience of the senior physicians influenced the choice of the clinical sites with moderate agreement (Kappa index: 0.4-0.6). CONCLUSION: Compared to the ACPA- group, the ACPA+ one had more lung-hyperinflation and OVI, and comparative percentages of RVI, MVI, and NSVI. CONCLUSION: LUS significantly improves the accuracy of pleural puncture sites, thus minimizing the risk of complications regardless of the operator's level of clinical experience.

Mental health status of healthcare workers at a third line Tunisian hospital during COVID-19 pandemic.

INTRODUCTION: During the COVID-19(coronavirus-19 disease) pandemic, health care workers (HCWs) faced the risk of infection and distressing work to meet health requirements. The aim of the present stud ywas to evaluate perceptions of HCWs of their security at work in COVID-19 units and their coping strategies, at the military hospital of Tunis, during the second wave of COVID-19. METHODS: A cross-sectional study was conducted via an auto-questionnaire on February 2021.HCWs of the military hospital of Tunis were included. Participants were asked about their perceived security at work in COVID-19 units and their coping behaviors. Mental disorders were assessed, via qualitative questionnaires. RESULTS: A total of 110 HCWs' responses were collected. Fifty-eight participants (52.7%) were females. The mean age was 33.7 years (SD 9.3). They were doctors at 45.5% and nurses at 39.1%. HCWs declared having worked in COVID-19 units in 81.8% of cases. The participants reported their fears about being infected in 58.2% and infecting family members in 85.5% of cases. Protective factors included information about the disease (80%), availability of personal protective equipment (PPE) (80.9%), support from colleagues(72.7%)or superiors at work (50.9%), and ability to communicate with others (63.6%). Depression, anxiety, and insomnia were found in respectively 25.5%, 30%, and 41.8% of HCWs. In multivariate analysis, suffering from a traumatic distress was significantly associated with anxiety and depression (p (p<0.01 and, p<0.05 respectively). In addition, insomnia severity was linked to age (p=0.05) and having colleagues infected with COVID-19 (p<0.05). CONCLUSION: In the present study, HCWs of the military hospital of Tunis stated having high levels of insomnia, anxiety, and depression since the early outbreak of the COVID-19 pandemic. These mental disorders may have a negative impact on the quality of life of HCWs and should be enhanced by psychological support and preventive measures.

Spontaneous Resolution of a Pulmonary Cystic Amyloidosis Mass.

Introduction: Amyloidosis is a rare illness characterized by the deposition in organs of amyloid, which can be detected by histological staining. Amyloidosis restricted to the lower respiratory tract is unusual. Results: We reported the case of a 68-year-old woman with no history of chronic diseasewho presented with dyspnoea on exertion, cough and fatigue. The physical examination was unremarkable. A CT scan showed a cystic mass with a thickened wall in the apical segment of the left lower lobe. A biopsy of the mass was performed, and histological and immunohistochemical study confirmed the diagnosis of AL amyloidosis. The patient's clinical and radiological symptoms spontaneously improved without treatment after 3 years. Conclusion: Amyloid-related cystic lung disease is a rare presentation of amyloidosis in the thorax. More case reports are required to determine if such masses can resolve without treatment and whether amyloid-associated cystic lung disease actually exists. LEARNING POINTS: Dyspnoea and cough are a rare atypical presentation that can reveal pulmonary amyloidosis.A cystic lung mass should raise suspicion for pulmonary amyloidosis.Clinical symptoms and radiological findings of a cystic mass spontaneously resolved without treatment after 3 years in this patient with pulmonary amyloidosis.

Evaluation of left ventricular systolic function in children with sickle cell anemia: contribution of 2D strain.

BACKGROUND: Cardiovascular involvement is not well studied in children with sickle cell disease. The aim of this study was to evaluate the echocardiographic parameters and to investigate speckle tracking echocardiography (STE) interest in detecting subclinical myocardial impairment of children with sickle cell disease. METHODS: The study was directed in the echocardiographic laboratory in the military hospital of Tunis between July 2018 and December 2018. 30 patients with sickle cell anemia (SCA) and 30 controls were compared. The echocardiographic measurements were indexed according to body surface. Cardiac output, left ventricular ejection fraction, wall thickness, as well as LV 2-D longitudinal systolic strain were assessed. RESULTS: The SCA Group included 30 patients (11.8 ± 2yrs, sex ratio: 1.31) with homozygous SCA and the C Group included 30 healthy controls (12.7 ± 1,2yrs, sex ratio: 1.27). According to the findings, SCA Group showed significantly larger LV diameter (36.2±2.5mm/m2 vs 29.3±1.3mm/m2, p=0.005). SCA Group also showed lower LV ejection fraction (62%±0.5 vs 65%±5, p=0.001). No significant difference was observed for cardiac output (p=0.4). Otherwise, two-dimensional longitudinal strain of LV was higher in SCA group (-21%±3.07 vs -25%±2.98; p<0.01). CONCLUSIONS: Our study highlights several cardiac abnormalities in children with SCA, which could represent a marker of disease severity and point out the importance of the cardiologic screening of these patients.

Parsonage-Turner syndrome of the brachial plexus secondary to COVID-19 vaccine: A case report.

Parsonage-Turner syndrome (PTS) is a peripheral inflammatory neuropathy of unknown etiology. We present a rare case of a 50-year-old male patient with PTS post-COVID-19 BNT162b2 mRNA vaccine. Symptoms occurred 15 days after the second dose. He was treated with corticosteroids, analgesics, and physical rehabilitation with a partial recovery.

Massive Haemoptysis Treated with Bronchial Artery Embolisation in COVID-19 Infection.

Background: Massive haemoptysis is a rare symptom ofcoronavirus disease 2019 (COVID-19). Management can be very challenging due to the lack of clear recommendations. Case description: We report a case of massive recurrent haemoptysis in a young patient who tested positive for COVID-19 with successful management using endovascular embolization. Discussion: Life-threatening massive haemoptysis has rarely been reported as the only manifestation of COVID-19. Embolisation was the therapeutic option chosen to manage this emergency. LEARNING POINTS: Haemoptysis is a rare atypical presentation that can reveal COVID-19, highlighting the complexity of its pathogenesis.Atypical manifestations should raise suspicion for COVID-19.In this patient with COVID-19, life-threatening massive haemoptysis was successfully treated with endovascular embolisation.

A recurrent side-changing febrile pleural effusion revealing familial Mediterranean fever: a case report.

Familial Mediterranean Fever (FMF), characterized by recurrent polyserositis, is an autosomal recessive disease involving essentially Mediterranean populations. We report the case of a 30-year-old Tunisian military patient complaining of fever and chest pain recurring on board a Navy military vessel, due to side-changing pleural effusion. On landing, a marked improvement of symptoms was noticed. Gene testing was performed when the diagnostic survey ruled out common etiologies, revealing a homozygous mutation of the FMF gene type M680l/M680l. The prescription of colchicine and the exemption from boarding led to the resolution of the symptoms with no recurrence of pleural effusion. Therefore, the diagnosis of FMF should be considered in a context of a recurrent pleural effusion in the youth, with a negative etiological assessment, notably in an ethnic group at risk. Thus, early diagnosis and adequate treatment may prevent the development of secondary amyloidosis, a serious complication of FMF.

Does incarceration change the profile of pulmonary tuberculosis in Tunisia?

INTRODUCTION: Tuberculosis of the prisoner remains unknown in Tunisia. The aim of our study was to establish the clinical, radiological, bacteriological and prognostic features of pulmonary tuberculosis in patients with a history of incarceration. METHODS: Case-control study conducted between 2010 and 2016 in two pulmonology departments of Abderrahmane Mami Hospital. The cases were male patients, hospitalized for pulmonary tuberculosis with a history of incarceration. Three controls for one case were randomly selected from the list of male patients hospitalized for pulmonary tuberculosis in the same departments as the cases but with no history of incarceration. RESULTS: The study included 58 cases and 174 controls. The average age of cases was lower than in controls (36,5 years vs 43,4 years; p <0.001). The cases had a significantly worse socioeconomic conditions and educational level with no more frequent social coverage of the disease. Risk factors for TB (smoking, alcoholism, substance abuse, unprotected sex, tuberculosis contagion, viral hepatitis C) were significantly higher among cases. Weight loss and night sweats were significantly more common in both cases, as was undernutrition. Positive bacilloscopies prevailed in the cases (36,5 vs 43,4;p = 0.047). In controls, the institution delay was longer (4.38 days vs 10.24 days; p= 0.004) and the total duration of treatment was lower (7.16 mounths vs 6.55 mounths; p = 0.048). CONCLUSION: Pulmonary TB in prisoner predominates in young people with poor socio-economic status and poor educational attainment. It is associated with several risk factors for TB and malnutrition. Health education in prisons is needed to combat this condition.
