Article Synopsis
- Lophomonas blattarum is a protozoan that primarily affects the lower respiratory tract, causing pulmonary lophomoniasis, but its radiologic findings had not been previously studied.
- A study involving 34 patients analyzed their demographic data and various radiological findings, noting that most findings occurred at frequencies below 50%.
- The most common findings were tree-in-bud nodules, alveolar consolidation, and bronchiectasis, predominantly in the right lung's middle and lower lobes, highlighting the need for awareness of this condition in differential diagnosis.
We report a 52-year-old patient with a history of breast cancer (BC) referred to the clinic of Afzalipour Hospital, in Kerman, eastern Iran, with a 1-week complaint of restless dyspnea. A chest computed tomography scan revealed consolidations in the upper lobes of both lungs. The patient had no history of smoking or underlying diseases that would predispose her to consolidation, including pneumonia.

There is some evidence suggests that bile acid micro-aspiration may contribute to the development of lung diseases. This study aimed to assess the prevalence of micro-aspiration of bile acids in patients with primary lung cancer.

Despite the importance of TBM, data on its prevalence and related factors are limited. In the current study, the prevalence and predictive factors of this illness were investigated.

There has been no study on the characteristics of the pleural fluid in anthracosis. The present study analyzed the biochemical characteristics of pleural effusion in patients with pulmonary anthracosis.

One of suggested risk factors for COPD is Gastroesophageal Reflux Disease (GERD). The aim of this study was investigation of the association between micro-aspiration of bile acid and pepsin with exacerbation attacks in COPD patients.

Methods: Fifty patients were randomly selected as 2 double-blinded sample groups (n=25).
Background: Lung cancer is one of the most common causes of death worldwide. Although smoking and environmental pollutants are the most important risk factors of lung cancer, the role of infectious causes should also be considered in the pathogenesis and progress of lung cancer.
Objectives: This study examined the relationship between and lung cancer through serology, real-time PCR, and urease tests.
