    Chronic eosinophilic pneumonia. Report of one case
    (SOC MEDICA SANTIAGO, 2016) Fernandez Bussy, Sebastian; Campos, Felipe; Ogueta, Isabel; Labarca, Gonzalo; Cabello, Hernan
    Chronic eosinophilic pneumonia (CEP) is uncommon and predominantly seen in women. More than 6% of eosinophils in peripheral blood and more than 25% in bronchoalveolar lavage are diagnostic criteria. Secondary causes of hypereosinophilic pneumonia must be ruled out. We report a 72-year-old non-smoker man presenting in the emergency room with a history of cough, fever, and moderate dyspnea. He was not taking any medication. A chest-X ray showed a left lower lobe (LLL) consolidation, and was started on broad-spectrum antibiotics with a presumptive diagnosis of pneumonia. There was no improvement after therapy. A chest CT scan showed increased LLL consolidation and new left upper lobe ground glass opacities as well as a moderate left pleural effusion. Flexible bronchoscopy was performed and bronchoalveolar lavage showed 95% eosinophils, and had negative cultures. No parasites were identified. Transbronchial biopsies demonstrated eosinophil accumulation in alveoli and interstitium and pleural fluid was composed by 85% eosinophils. With the diagnosis of CEP, systemic corticosteroids were used with favorable clinical and radiological response.

    Treatment failure in community-adquired pneumonia: coccidioidomycosis in a traveler patient
    (SOC CHILENA INFECTOLOGIA, 2013) Cabello, Hernan; Labarca, Gonzalo; Fernandez Bussy, Sebastian; Cabello, Francisca; Pires, Yumay; Soto, Rodrigo; Thompson, Luis
    Treatment failure in community-acquired pneumonia is defined as a clinical condition with inadequate response to antimicrobial therapy. Resistant and unusual microorganisms and noninfectious causes are responsible for treatment failure. Coccidioides immitis is a fungus that causes pneumonia in the northern hemisphere, especially in the United States and northern Mexico. We report a case of pulmonary coccidioidomycosis imported from Mexico to Chile. After a comprehensive study, histopathology was able to establish Coccidiodes immitis as the causative agent, achieving clinical and radiological improvement with antifungal therapy.
