Case ReportsPulmonary alveolar microlithiasis and probe-based confocal laser endomicroscopy.
Pulmonary alveolar microlithiasis (PAM) is a rare disease in which calcium-phosphate microliths accumulate within the alveolar space. We report cases of 2 siblings with PAM, presenting differently as regards the distribution and clinical severity. Immune cytologic analysis of bronchoalveolar lavage showed a CD4 alveolitis in the radiologically most affected patient, whereas the least affected had a normal bronchoalveolar lavage analysis, demonstrating the low specificity of immune cytologic lavage analysis in diagnosing familial PAM. For the first time, we describe the endoscopic findings using a probe-based confocal laser endomicroscopy.

Diagnostic yield of EBUS-TBNA for the evaluation of centrally located peribronchial pulmonary lesions.
The purpose of this study was to evaluate the diagnostic yield of endobronchial ultrasound with real-time-guided transbronchial needle aspiration (EBUS-TBNA), endobronchial forceps biopsy (EBBx), and 2D fluoroscopic-guided transbronchial forceps biopsy (TBLBx) for centrally located peribronchial lung lesions. ⋯ Where available, EBUS-TBNA of centrally located peribronchial lung lesions should be given a strong consideration given its high diagnostic yield.

ReviewLinear EBUS in staging non-small cell lung cancer and diagnosing benign diseases.
As an evolving technique, linear endobronchial ultrasound is becoming the first choice and standard of care not only to diagnose the malignant and benign mediastinal lesions but also to stage non-small cell lung cancer. Lung cancer is the leading cause of cancer-related mortality in both men and women. The disease causes more death compared with colorectal, breast, and prostate cancers combined in the United States. ⋯ Determining the cell type and its molecular characteristics allow targeted treatments in adenocarcinoma. The diagnosis of indeterminate mediastinal lymph nodes or masses and staging lung cancer might be challenging. This article will review the principles and clinical utility of endobronchial ultrasound in mediastinal lesions.

Case ReportsTreatment of severe advanced emphysema with volume reduction using lung sealant: a case report of 2 patients.
Emphysema is a progressive and irreversible disease for which there is no cure to date. The patients experience debilitating shortness of breath with repetitive exacerbations and poor quality of daily life. At present, patients with severe emphysema have limited treatment options. Endoscopic lung-volume reduction with valve implantation or using lung sealant is a treatment option for patients with severe emphysema. By our patients, we detected collateral channels, which allow airflow into the target lobe and prevent atelectasis and significant lung-volume reduction. Thus, we decided to treat the advanced emphysema of our patients with endoscopic volume reduction using lung sealant (AeriSeal). Lung-volume reduction surgery reduces hyperinflation and improves lung function by removal of emphysematous lung tissue. However, lung-volume reduction surgery is also associated with significant short-term morbidity and mortality. Results from recently published Endobronchial Valve for Emphysema Palliation Trail (VENT) and Exhale Airway Stents for Emphysema (EASE) trial showed that treatment was substantially less effective and did not consistently reduce hyperinflation or improve lung function mostly likely due to collateral ventilation present in majority of patients. There is a volume reduction therapy in case of detection of collateral flow; use of a lung sealant is a possible alternative. ⋯ Correlation and comparisons between changes in primary and secondary outcome measures in the lung function parameters and 6-minute walking test before and after the application of AeriSealant revealed significant reduction of hyperinflation and improvement both in the flow rates and physical capacity of our patients.

Case ReportsEndobronchial ultrasound diagnosis of pulmonary embolism.
A 68-year-old woman presented for mediastinal lymph node sampling while undergoing work up for a solitary pulmonary nodule. During endobronchial ultrasound examination of the airways, an echogenic abnormality was noted within the right pulmonary artery. The patient underwent computed tomography angiography of the chest, and diagnosis of pulmonary embolism was confirmed. We describe endobronchial ultrasound evaluation of a pulmonary embolus.
