Obstructive fibrinous tracheal pseudomembrane.

Obstructive fibrinous tracheal pseudomembrane is a rare but potentially fatal complication associated with endotracheal intubation. Little is known about the mechanisms that play a role in the development of tracheal pseudomembrane, but it requires early diagnosis and treatment to prevent its major consequences. In this report, we present a case of obstructive fibrinous tracheal pseudomembrane, which developed a day after extubation in a patient who was intubated for 2 days. Therapeutic bronchoscopy was highly successful in removing the lesion and improving the clinical course.

Evaluation of dynamic thiol/disulfide redox state in community-acquired pneumonia

Objectives To compare dynamic thiol/disulfide homeostasis between patients with community-acquired pneumonia (CAP) and healthy controls. Methods This prospective, case-control study was conducted in the Department of Pulmonary Diseases, Ankara Ataturk Training and Research Hospital, Yildirim Beyazit University, Ankara, Turkey, between August 2016 and August 2017. In total, 50 hospitalized patients with CAP and 35 healthy individuals were enrolled. Patients with comorbidities and smokers were excluded. The thiol/disulfide state was evaluated in each group. Thiol levels (native/total) and % polymorhonuclear leukocytes and C-reactive protein levels association were evaluated in patients with CAP. Results There was no significant difference between the CAP and control groups in age or gender (both, p>0.05). The disulfide (SS) levels were similar between the 2 groups (p=0.148). The total thiol (TT) and native thiol (SH) levels were significantly lower (all, p=0.001) and the SS/TT levels were significantly higher (p=0.019) in the CAP group compared with the controls. Conclusions This study showed that the oxidant/antioxidant ratio was shifted to the oxidative side in CAP patients. An abnormal thiol/disulfide state may be an important factor in the pathogenesis and monitoring the treatment response. The thiol resources may use for treatment in CAP and may positively affect the prognosis.

A case of pulmonary artery hydatid cyst observed on endobronchial ultrasound.

Hydatid cyst (HC) is a parasitic disease that may involve many organs, especially the lung and the liver. Pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. We report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. Thoracic computed tomography showed filling defects in the pulmonary arteries. Endobronchial ultrasound was performed for differential diagnosis and it showed a cystic lesion. Hydatid cyst-specific IgE and hem agglutination test results were positive. In the literature, cases like this in which the diagnosis of pulmonary hydatid cyst is made by endobronchial ultrasound are not usually seen. Although many imaging modalities such as plain chest radiography, cross-sectional imaging (MDCT and MRI), echocardiography and conventional pulmonary angiography have been used in the diagnostic approach, we recommend endobronchial ultrasound for the differential diagnosis of cases with cystic formation.

A Case of Legionella Pneumonia with Pleuropericardial Effusion

efüzyon, letarji, renal tübüler disfonksiyon ABSTRACT Multi-organ involvement is common in Legionella infections. In this paper, a 72-year-old female patient with pleuropericardial involvement, renal tubular dysfunction and impaired mental status, diagnosed as Legionella infection with the positive urinary Legionella antigen is presented since pericardial involment of Legionella is rarely seen.
