RESUMO
Introduction: Coronavirus disease 2019 is a global health threat often accompanied with coagulopathy. Despite use of thromboprophylaxis in this population, thrombotic event rates are high. Materials and methods: This was a multicenter, retrospective cohort study comparing the safety and effectiveness of thromboprophylaxis strategies at 2 institutions in hospitalized patients with coronavirus disease 2019. Regimen A utilized a higher-than-standard thromboprophylaxis dosage and Regimen B received full-dose anticoagulation for any D-dimer 3 mcg/mL or greater and prophylactic for less than 3 mcg/mL. The primary outcome compared the rate of thrombotic events between treatment groups. Secondary endpoints compared rates of major or clinically relevant non-major bleeding as well as the proportion of patients in each group experiencing thrombotic events within 30 days of discharge. Results: One-hundred fifty-three patients were included in the analysis, 64 receiving Regimen A and 89 receiving Regimen B. Seven (4.6%) thrombotic events occurred, 3 (4.7%) in patients receiving Regimen A, and 4 (4.5%) in Regimen B (P = 1.0). Twelve patients (13.5%) receiving Regimen B had a bleeding event versus 2 (3.1%) in Regimen A (P = .04), half of which were major in each group. All patients who bled in either treatment group were receiving mechanical ventilation, and 12 of 14 were receiving full-dose anticoagulation. One patient receiving Regimen A was readmitted with a pulmonary embolism. Conclusions: In this study, the thromboprophylactic regimen impacted bleeding, but no significant difference was seen with thrombotic outcomes. Almost all patients who experienced a bleed were mechanically ventilated and receiving full-dose anticoagulation. The use of full-dose anticoagulation should be cautioned in this population without an additional indication.
RESUMO
We present the case of a young woman transferred to our center with acute hypoxic respiratory failure due to an obstructing subcarinal mass. We review the management and rationale of this respiratory failure at different stages of her hospital course. We describe the approach and rationale in both the intensive care unit as well as the bronchoscopy suite. Finally, we discuss how the use of a novel hybrid Y stent effectively palliated her symptoms.
RESUMO
INTRODUCTION: We present two cases with symptoms of progressively worsening cough, dyspnea, decreased exercise tolerance and right-sided back pain in the first case and upper respiratory symptoms characterized by cough and a low grade fever in the second case. METHODS: Report of two cases. RESULTS: The initial chest X-ray in both the cases showed pleural effusion. Further imaging with computed tomography of the chest confirmed the effusion in both cases. Thoracentesis was done in both of them revealed an exudative effusion that did not reveal any infection or malignancy. Both cases underwent surgical biopsy and the diagnosis of primary pleural epithelioid hemangioendothelioma was made. CONCLUSIONS: Both the cases had progressive clinical deterioration despite chemotherapy with Taxol and Bevacizumab in one case and carboplatin, etoposide, and bevacizumab, in the second case. Both developed metastatic disease to lungs and died.

Bronchiectasis is characterized by permanent, abnormal dilation of the bronchi with chronic inflammation and infection. Bronchiectasis is either caused by or associated with several systemic disorders, and in a significant number of cases, the underlying etiology remains unidentified and is subsequently referred to as idiopathic. The clinical course is characterized by chronic cough with purulent sputum associated with acute exacerbations. Patients may develop progressive decline in pulmonary function due to ongoing infection, inflammation, and destruction of bronchi if a delay in diagnosis and therapy occurs. With high-resolution computed tomography, the confirmatory diagnosis of bronchiectasis can be made promptly and diagnostic work-up for etiology initiated. Identifying a specific etiology, when present, is critical for implementing appropriate treatment of the underlying cause. Whether a specific etiology can be identified or not, all cases of bronchiectasis require management that addresses infection, inflammation, and bronchial toilet.
