Primary pulmonary synovial sarcoma (SS) is a rare neoplasm. Its clinicoradiologic attributes are not yet well defined. We report the observation of a patient followed for primary pulmonary synovial sarcoma. we report the radio-clinical features of this rare tumor.

The COVID-19 disease is a multisystem disease due in part to the vascular endothelium injury. Lasting effects and long-term sequelae could persist after the infection and may be due to persistent endothelial dysfunction. Our study focused on the evaluation of endothelial quality index (EQI) by finger thermal monitoring with E4 diagnosis Polymath in a large cohort of long COVID-19 patients to determine whether long-covid 19 symptoms are associated with endothelial dysfunction. This is a cross-sectional multicenter observational study with prospective recruitment of patients. A total of 798 patients were included in this study. A total of 618 patients (77.4%) had long COVID-19 symptoms. The mean EQI was 2.02 ± 0.99 IC95% [1.95–2.08]. A total of 397 (49.7%) patients had impaired EQI. Fatigue, chest pain, and neuro-cognitive difficulties were significantly associated with endothelium dysfunction with an EQI

The onset of a spontaneous hemothorax may represent a life threatening emergency. Several etiologies may be involved, mainly vascular abnormalities. Pulmonary Arterio Venous Malformation (PAVM) is a rare etiology, and it is often associated with Hereditary Hemorrhagic Telangiectasia HHT. We report the case of a young women who was presented to the emergency department with left basal chest pain and mild dyspnea. Hemodynamic and respiratory states were maintained. Vesicular murmuring was abolished on the left side. The chest roentgenogram showed a left pleural effusion with mild deviation of the mediastinum to the opposite side. Thoracocentesis found a serohematic liquid. While the patient was undergoing exploration by computed chest tomography, she represented a cardio respiratory arrest. Resuscitation was successful after few minutes. The chest CT showed a PAVM located on the upper lobe that was very enhanced after injection of the contrast product, with a feeding artery coming from the pulmonary artery. The patient underwent an emergent left upper lobectomy thorough a posterolateral thoracotomy. The PAVM was peripheral, large with a diameter of 5 cm, and ruptured on the pleural cavity. Elective controlling the hemorrhage was very difficult, so a total hilar clamping was done with a Satinsky clamp. The postoperative course was complicated with pulmonary embolism managed by anticoagulation treatment. The definitive histological management concluded to a PAVM. Retrospectively, there was no personal or familial sign of HHT, neither any anomaly of blood hemostasis. Isolated PAVM is a rare cause of spontaneous hemothorax. Rapid worsening of an initially maintained state makes the situation more critical. Rapid control of a massive bleeding is mandatory to better explore and plan surgical resection. For stable patient, endovascular treatment may represent an effective option.

Background: Obstructive sleep apnea hypopnea syndrome (OSAHS) has been shown to be associated with many serious health conditions. The impact on occupational health is still unclear as it was scarcely studied. Purpose: The aim of this study was to assess the association of work performance with OSAHS and daytime sleepiness. Methods: A cross-transversal study was conducted including Tunisian active adult subjects referred for suspected sleep disordered breathing. All subjects completed the Epworth Sleepiness Scale (ESS), the Work Productivity and Activity Impairment Questionnaire (WPAI), and the Patient Health Questionnaire 9 (PHQ9). They all underwent polygraph testing level 3. Result: One hundred thirty-nine subjects completed the survey, including 107 (77%) blue-collar workers, and 32 (23%) white-collar workers. Participants were classified as following: 50 patients with apnea hypopnea index (AHI) ≥ 30 and 89 with AHI
