Correlation of spirometry findings and post-six-minute walk test oxygen desaturation in chronic simple silicosis patients with age, duration of silica exposure, smoking pack years, occupation and mean pulmonary artery pressure.

Silicosis is associated with preventable but irreversible lung damage. Early quantifiable assessment of silicosis workers would promote early interventional steps to reduce health deterioration. The objectives of this study were to correlate spirometry findings and post-six-minute walk test oxygen desaturation (post-6MWT OD) in chronic simple silicosis with age, duration of silica exposure (DSE), smoking pack years (SPY), occupation, and mean pulmonary artery pressure.

Prevalence of pulmonary hypertension in chronic simple silicosis patients and its correlation with smoking history, occupation type, age and duration of silica exposure.

Silicosis is a preventable occupational health hazard with potential for permanent physical disability and increased socio-economic burden. Pulmonary hypertension (PH) secondary to chronic respiratory diseases signifies poorer prognosis and transthoracic echocardiography (TTE) has proven its usefulness as a screening tool for PH diagnosis. The objectives were to determine PH prevalence in chronic simple silicosis patients through TTE screening and correlate PH prevalence with smoking status, occupation type, age and duration of silica exposure (DSE).

Diagnostic accuracy of semirigid thoracoscopy in exudative pleural effusions and relationship of thoracoscopic findings with probability of malignant diagnosis.

Semirigid thoracoscopy is increasingly becoming the procedure of choice for evaluation of undiagnosed exudative pleural effusions. Few studies have reported relationship of thoracoscopic appearances of pleural abnormalities and etiological diagnoses. We aimed our study to assess the diagnostic utility and safety of semirigid thoracoscopy for evaluation of patients with undiagnosed exudative pleural effusion.

Benign Endobronchial Inflammatory Polyp with Cystic Degeneration: A Case Report.

Endobronchial lesions causing luminal obstruction are mostly found in bronchogenic carcinoma. Inflammatory polyps originating from the tracheobronchial tree are rarely found. Here we report a case of an elderly male presenting with prolonged cough who was found to have an endobronchial inflammatory polyp.

Spontaneous Partial Regression of a Carcinoid Tumor: Radiology May Not Capture the Real Picture.

A partial or complete resolution of the neoplastic lesion, either spontaneously or in the presence of therapy that is considered inadequate to exert significant influence on the growth of the neoplastic lesion, is considered a spontaneous regression. This phenomenon is extremely rare in lung neoplasms. A close follow up with imaging along with bronchoscopy and a biopsy of the lesion is essential, as they may have potential for distant spread even during radiological regression.

Comparison of Diagnostic Potential of Narrow Band Imaging Bronchoscopy Over White Light Bronchoscopy in Lung Cancer.

Background: Worldwide, lung cancer is the largest contributor to new cancer diagnoses and to death from cancer. Narrow band imaging (NBI) is a novel bronchoscopic technique which enables detailed examination of submucosal microcapillary grid and showed great potential in early detection of malignant lesions of the bronchial mucosa. The aim of this study was to compare diagnostic potential of NBI bronchoscopy over white light (WL) bronchoscopy in lung cancer.
