Six and twelve-month respiratory outcomes in a cohort of severe and critical COVID-19 survivors: A prospective monocentric study in Latin America.

Introduction: Severe COVID-19 can result in long-term sequelae known as "chronic COVID," characterized by a wide range of persistent physical and mental symptoms. Chest imaging and pulmonary function test alterations have been observed in recovered patients. Most studies focus on up to a 3-month follow-up after symptom onset or hospital discharge, with few reports on long-term follow-up and limited evidence regarding disease progression in Latin America.

Pulmonary Alveolar Microlithiasis in a Young Man Undergoing Lung Transplantation: A Case Report.

Pulmonary alveolar microlithiasis is a rare disease characterized by the deposition of microliths in the alveoli, attributed to mutations in the solute carrier family 34 member 2 () gene. Diagnosis is often incidental to chest imaging, most frequently occurring between the second and fourth decades of life. The disease follows a progressive course and manifests with a clinical-radiological dissociation.

Severe cryptogenic bronchiolitis: Case report.

Bronchiolitis obliterans (BO) is a progressive fibrotic process that predominantly affects the small airways and is identified as constrictive bronchiolitis by pathologists. It is commonly associated with allogeneic hematopoietic stem cell transplant (HSCT), lung transplant, exposure to inhaled toxins, post-infectious processes, autoimmune diseases, and sometimes, no known cause. In the latter case, it is referred to as cryptogenic bronchiolitis obliterans.

Invasive Aspergillosis in a Patient With Diabetes Mellitus as the Only Risk Factor: Case Report and Literature Review.

Infection by covers a broad clinical spectrum, including invasive pulmonary aspergillosis (IPA) and its disseminated extrapulmonary form, invasive aspergillosis (IA). It typically occurs in severely immunocompromised hosts, but it sometimes affects the immunocompetent population, especially patients with acute diseases being treated at the intensive care unit (ICU) and less often those with chronic conditions. In this article, we report the case of a 50-year-old male, with diabetes mellitus (DM) as the only risk factor, treated for IPA and IA with cardiac and central nervous system (CNS) involvement at a high complexity institution in Cali-Colombia.

Introduction: Non-cystic fibrosis bronchiectasis (NCFBE) is a chronic and progressive disease characterized by the permanent destruction of small and mid-sized airways. Many patients are chronically colonized by Pseudomona aueruginosa, for which oral antibiotics are given. Evidence to support the use of inhaled antibiotics is contradictory.

Sternal cavernous hemangioma and reconstruction of the anterior chest wall: a case report.

Background: The sternum is considered an unusual tumor site, corresponding to 15% of all thoracic wall tumors. Primary sternal tumors are even rarer and most commonly malignant. We present the case of a young man who consulted with a painful sternal mass, which after its resection is confirmed to be a cavernous hemangioma.

Immune Thrombocytopenic Purpura, a rare manifestation of active tuberculosis: Case report.

Tuberculosis is currently considered a public health issue worldwide. Although a large number of hematological disorders related to tuberculosis have been described, immune thrombocytopenic purpura in patients with active tuberculosis is very rare but must be considered in a patient with no other evident cause.

Use of monoclonal antibodies for allergic bronchopulmonary aspergillosis in patients with asthma and cystic fibrosis: literature review.

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction (HR) mediated by antigens to . It is estimated that 2-15% of patients with cystic fibrosis (CF) and between 1% and 5% of asthmatics develop ABPA, affecting approximately 4.8 million people worldwide.

Endobronchial ultrasound-guided Transbronchial needle aspiration (EBUS-TBNA) in simulator lesions of pulmonary pathology: a case report of pulmonary Myospherulosis.

Background: Myospherulosis develops as the result of a reaction between exogenous lipids and red blood cells (RBC) of the patient, being the latter injured when perceived as a foreign body by the immune system, triggering an intense inflammatory response.

Case Presentation: A 63-year-old man with a history of dyslipidemia, Barret's esophagus, and coronary disease, who was taken to thoracoscopy and left inferior lobectomy due to the presence of a pulmonary mass. A primary pulmonary adenocarcinoma was diagnosed.

Thoracic Computed Tomography Scan and Bronchoscopy Appearance of Mounier-Kuhn Syndrome: A Case Report.

Mounier-Kuhn syndrome (MKS) is a rare congenital disease with an autosomal recessive inheritance pattern, characterized by an enlargement of the trachea and bronchi. MKS is secondary to a thinning of the muscular mucosa and atrophy of the longitudinal muscle and elastic fibers of the tracheobronchial tree. As a consequence, tracheal diverticulosis and dilatations in the posterior membranous wall appear, along with bronchiectasis that tend to be cystic in appearance.

Unsuspected foreign-body aspiration in adult patient with status asthmaticus: Case report.

Introduction: Accidental foreign body aspiration can cause severe damage to the airway and threaten the patient's life. This situation requires multidisciplinary and systematic approach from the medical and surgical team, in order to achieve complete resolution maintaining airway permeability.
