Microbiology and prognosis assessment of hospitalized patients with aspiration pneumonia: a single-center prospective cohort study.

Aspiration pneumonia has a high incidence in hospitalized patients with community-acquired pneumonia and results in high mortality rates. We aimed to evaluate microbiology and assess prognostic factors of aspiration pneumonia in the setting of a tertiary hospital pulmonology department. Community-acquired (CAAP) and healthcare-associated aspiration pneumonia (HCAAP) cases hospitalized over a period of a year were prospectively followed.

Unilateral pulmonary hypoplasia in an adult patient.

Pulmonary hypoplasia (PH) is a developmental anomaly of the lung parenchyma, characterized by a decrease in the number and size of airways, alveoli and vessels. We present a case of a 31-year-old patient with a history of chronic productive cough and frequent respiratory infections, who was referred for investigation of abnormal chest x-ray. The combination of chest computed tomography (CT) and bronchoscopy set the diagnosis of left pulmonary hypoplasia and the patient was treated surgically with a left pneumonectomy.

25-hydroxyvitamin D in malignant pleural disease: a prospective cohort study.

Introduction: Growing evidence suggests a role of vitamin D in various cancers but the significance of vitamin D in malignant pleural disease remains unexplored. We sought to investigate the concentration and diagnostic role of 25-hydroxyvitamin D (25(OH)D) in malignant pleural effusions.

Materials And Methods: Prospective study of consecutive treatment-naïve patients with a new diagnosis of pleural effusion.

Cryptogenic and secondary organizing pneumonia: clinical presentation, radiographic findings, treatment response, and prognosis.

Background: Organizing pneumonia (OP) is a distinct clinical and pathologic entity. This condition can be cryptogenic (COP) or secondary to other known causes (secondary OP). In the present study, we reviewed the features associated with COP and secondary OP in patients from two teaching hospitals.

Malignant conversion of a solitary papilloma in the distal trachea: report of a case.

A solitary papilloma versus the usual multiple lesions of papillomatosis is extremely rare. Even more infrequent is a solitary papilloma of the trachea in an adult patient. In the present report, a case of a solitary papilloma in the distal trachea is presented.
